Administration of Intravenous Vitamin C in Novel Coronavirus Infection (COVID-19) and Decreased Oxygenation (AVoCaDO)

Previous research has shown that high dose intravenous vitamin C (HDIVC) may benefit patients with sepsis, acute lung injury (ALI), and the acute respiratory distress syndrome (ARDS). However, it is not known if early administration of HDIVC could prevent progression to ARDS. We hypothesize that HDIVC is safe and tolerable in COVID-19 subjects given early or late in the disease course and may reduce the risk of respiratory failure requiring mechanical ventilation and development of ARDS along with reductions in supplemental oxygen demand and inflammatory markers.

The death of George Floyd and other African Americans spurred the Association of Black Cardiologists, the American Heart Association, and the American College of Cardiology to join forces and issue an urgent letter denouncing recent and ongoing events.

Starting off by acknowledging that these are “difficult and disturbing times,” the presidents of the three societies tied the violence into the bigger public health picture. “Like cardiovascular disease, acts of violence and racism are core causes of psychosocial stress that promote poor well-being and cardiovascular health, especially for communities of color.”

“It’s not just one quick solution, one quick letter. It’s more of an ongoing project to raise awareness and have really defined projects. We want to have goals, tactics, and measurable outcomes. We want to make sure it’s not just a banner on the wall,” Athena Poppas, MD, president of the American College of Cardiology and one of three physicians signing the letter, said in an interview.

The Association of Black Cardiologists drafted the statement and asked the AHA and ACC if they wanted to sign on. “It felt important to join them and follow their lead,” she said. “There is a clear link between psychosocial stress and discrimination and health equity in the communities.”

Interestingly, the ABC and ACC have an existing partnership, one that included creating a “Campaign for the Future” a little more than a year ago. One of the focuses is on reducing health disparities and starting a diversity and inclusion task force that later became a committee. The groups held a joint board of trustees meeting at Morehouse University, Atlanta, in January 2020. Thinking about that time, Dr. Poppas added, “who knew what was about to transpire over the next few months?”

The letter is only one component of an ongoing effort to “find concrete ways to make change, both within the college and within our profession,” added Dr. Poppas, chief of cardiology and professor of medicine at Brown University, Providence, R.I., and director of the Lifespan Cardiovascular Institute of Rhode Island, Miriam Hospitals, and Newport Hospitals. “Thereby, there is good data that you affect health equity in the population as well.”

“We DENOUNCE incidents of racism and violence that continue to ravage our communities,” the society leaders wrote in the letter. “Given that heart disease and stroke are the leading causes of death for communities of color, particularly African Americans who have the lowest life expectancy of all racial/ethnic groups living in the United States, we are extremely disturbed by violent acts that cut to the core of the lives of our community.”

Other societies released similar statements. For example, the American College of Physicians expressed “grave concern” about recent events and the American Medical Association released a statement entitled “Police brutality must stop.”

A cardiologist speaks out

“Thank you to my organizations, the Association of Black Cardiologists and the American College of Cardiology, for taking a stand,” Travis C. Batts, MD, said in a video statement posted to YouTube on June 2, 2020.

“As an African American male who has sons, brothers, and friends who are also African American, I oftentimes have angst, particularly with my sons. Despite what I do to create an environment that cultivates education and puts them in the right position, there are some people who would stop just at how they look when they approach them,” Dr. Batts said.

“I always have that fear as a father that at some point they may engage with law enforcement – and it may not turn out the way we want it to,” said Dr. Batts, chairman of medical sub-specialties and medical director of the cardiology clinic at Wilford Hall Ambulatory Surgical Center at Lackland Air Force Base, Tex. He also is an associate professor of cardiovascular medicine for the Uniformed Services University of the Health Sciences, Bethesda, Md., and is an adjunct assistant professor at Texas A&M University. He went on in the video to describe how a personal encounter with police years ago changed his life.

The urgent letter from the cardiology societies speaks to health care disparities, Dr. Batts said, “but it doesn’t stop there. It talks about their goals to balance these issues that we see as a pervasive problem in our community.”

The societies point out that George Floyd’s death is not an isolated incident. “Mr. Floyd’s death comes on the heels of other recent incidents caught on camera. In another 2020 incident, Ahmaud Arbery was shot and killed while jogging in his hometown of Brunswick, Ga. Christian Cooper is fortunately alive and well to speak to the Memorial Day incident in New York’s Central Park where he was accused of threatening the life of a woman while bird watching.” They added that “another senseless death involves officers entering the Louisville, Kent., home of emergency medical technician Breonna Taylor.”

Dr. Batts said this portion of the statement was particularly poignant: “We stand and link arms in solidarity with efforts to dismantle systems that maintain excess morbidity and mortality, especially among vulnerable populations and those historically oppressed. Indeed, our collective vast membership, many of whom are at the front lines of clinical health care, has taken an oath to decisively and with kindness, compassion and grace act to relieve suffering related to ‘I can’t breathe’ in order to preserve life.”

A Positive Response

The response to the urgent letter has been “overwhelmingly positive,” Dr. Poppas said. “This isn’t political, per se. This is really about justice, about health equity, and about being moral and conscious human beings. People I hadn’t heard from in years said, ‘thank you for doing this.’ ” The comments on social media were “almost uniformly positive,” she added. “There is always one or two people who feel this isn’t what cardiology is about.”

“Although making a statement is important, so is doing the hard work to make change,” Dr. Poppas said. The goal involves “rolling up our sleeves and spending the time, the money and the energy to make changes – so 5-10 years from now, it looks different.”

In addition to Dr. Poppas, Michelle A. Albert, MD, MPH, president of the Association of Black Cardiologists and Robert A. Harrington, MD, president of the American Heart Association, signed the letter. Dr. Pappas and Dr. Batts had no relevant disclosures.

Thinking about that time, Dr. Poppas added, “who knew what was about to transpire over the next few months?”

The letter is only one component of an ongoing effort to “find concrete ways to make change, both within the college and within our profession,” added Dr. Poppas, chief of cardiology and professor of medicine at Brown University, Providence, R.I., and director of the Lifespan Cardiovascular Institute of Rhode Island, Miriam Hospitals, and Newport Hospitals. “Thereby, there is good data that you affect health equity in the population as well.”

“We DENOUNCE incidents of racism and violence that continue to ravage our communities,” the society leaders wrote in the letter. “Given that heart disease and stroke are the leading causes of death for communities of color, particularly African Americans who have the lowest life expectancy of all racial/ethnic groups living in the United States, we are extremely disturbed by violent acts that cut to the core of the lives of our community.”

Other societies released similar statements. For example, the American College of Physicians expressed “grave concern” about recent events and the American Medical Association released a statement entitled “Police brutality must stop.”

A cardiologist speaks out

“Thank you to my organizations, the Association of Black Cardiologists and the American College of Cardiology, for taking a stand,” Travis C. Batts, MD, said in a video statement posted to YouTube on June 2, 2020.

“As an African American male who has sons, brothers, and friends who are also African American, I oftentimes have angst, particularly with my sons. Despite what I do to create an environment that cultivates education and puts them in the right position, there are some people who would stop just at how they look when they approach them,” Dr. Batts said.

“I always have that fear as a father that at some point they may engage with law enforcement – and it may not turn out the way we want it to,” said Dr. Batts, chairman of medical sub-specialties and medical director of the cardiology clinic at Wilford Hall Ambulatory Surgical Center at Lackland Air Force Base, Tex. He also is an associate professor of cardiovascular medicine for the Uniformed Services University of the Health Sciences, Bethesda, Md., and is an adjunct assistant professor at Texas A&M University. He went on in the video to describe how a personal encounter with police years ago changed his life.

The urgent letter from the cardiology societies speaks to health care disparities, Dr. Batts said, “but it doesn’t stop there. It talks about their goals to balance these issues that we see as a pervasive problem in our community.”

The societies point out that George Floyd’s death is not an isolated incident. “Mr. Floyd’s death comes on the heels of other recent incidents caught on camera. In another 2020 incident, Ahmaud Arbery was shot and killed while jogging in his hometown of Brunswick, Ga. Christian Cooper is fortunately alive and well to speak to the Memorial Day incident in New York’s Central Park where he was accused of threatening the life of a woman while bird watching.” They added that “another senseless death involves officers entering the Louisville, Kent., home of emergency medical technician Breonna Taylor.”

Dr. Batts said this portion of the statement was particularly poignant: “We stand and link arms in solidarity with efforts to dismantle systems that maintain excess morbidity and mortality, especially among vulnerable populations and those historically oppressed. Indeed, our collective vast membership, many of whom are at the front lines of clinical health care, has taken an oath to decisively and with kindness, compassion and grace act to relieve suffering related to ‘I can’t breathe’ in order to preserve life.”

A Positive Response

The response to the urgent letter has been “overwhelmingly positive,” Dr. Poppas said. “This isn’t political, per se. This is really about justice, about health equity, and about being moral and conscious human beings. People I hadn’t heard from in years said, ‘thank you for doing this.’ ” The comments on social media were “almost uniformly positive,” she added. “There is always one or two people who feel this isn’t what cardiology is about.”

“Although making a statement is important, so is doing the hard work to make change,” Dr. Poppas said. The goal involves “rolling up our sleeves and spending the time, the money and the energy to make changes – so 5-10 years from now, it looks different.”

In addition to Dr. Poppas, Michelle A. Albert, MD, MPH, president of the Association of Black Cardiologists and Robert A. Harrington, MD, president of the American Heart Association, signed the letter. Dr. Pappas and Dr. Batts had no relevant disclosures.

To the Editor: COVID-19 is a pandemic caused by the virus SARS-CoV-2. Serious complications of COVID-19 are characterized by acute respiratory distress syndrome (ARDS), pneumonia and rapidly progressing to multiorgan dysfunction syndrome (MODS).

The pathophysiology of COVID-19 is not fully understood yet and neither vaccine nor clearly effective antiviral treatment is available at this time. Based on the endothelial pathogenesis of viral sepsis, which includes ARDS as seen in severe acute respiratory syndrome (SARS) due to SARS-CoV and Middle East respiratory syndrome due to MERS-CoV,^1,2 we believe COVID-19-associated ARDS is also caused by endotheliopathy-associated vascular microthrombotic disease (EA-VMTD), which also involves multiorgan dysfunction syndrome (MODS) that has been reported as the cause of death.³ We suspect these complications are secondary to disequilibrium state (for various reasons^4,5) between insufficient ADAMTS13 and excessive exocytosis of ultra large von Willebrand factor multimers (ULVWF) from Weibel-Palade bodies present in endothelial cells due to COVID-19-induced endotheliopathy.

Endothelial-derived ULVWF multimers anchored to the endothelial surface of the vascular wall recruit platelets and initiate microthrombogenesis within the microvasculature, leading to large microthrombi strings composed of platelet and eULVWF complexes like “beads-on-a-string structures”⁶ where platelets firmly adhere to eULVWF, instead of roll on eULVWF strings.⁴ Platelets, once adhered to eULVWF strings, are rapidly activated causing platelet aggregation and also recruit leukocytes in a P-selectin dependent manner.⁴ These aggregates grow until they become sufficiently large and can no longer be held onto the eULVWF strings against the force of blood flow and released from endothelial cells into the circulation.⁴ It appears to us that in COVID-19 microthrombotic disease, large amounts of circulating complexes of endothelial-derived ULVWF decorated-platelet microthrombi strings are filtered in the microvasculature (embolism) or develops in the microvasculature in situ causing microthrombotic occlusion. During our data search, we have come across several articles published by Chang, including on endotheliopathy causing vascular microthrombotic disease based on a novel concept of “TTP-like syndrome”⁷

The genesis of EA-VMTD in TTP like syndrome is suspected to be triggered by complement activation and terminal complement complex (C5b-9, membrane attack complex, MAC) may play a key role in producing endotheliopathy.⁷ Magro and colleagues reported that COVID-19 patients have demonstrated generalized thrombotic microvascular injury involving the lungs and skin showing intense complement activation and C5b-9 deposition in the tissue.⁸ Also, recent pathology reports of COVID-19 diseased lungs showed extensive platelet-rich clotting with adherent mononuclear cells and extensive fibrin clotting,⁹ which appear consistent with involvement of NETosis.¹⁰ In another case report from Switzerland, a patient with severe COVID-19 had massive elevation of VWF antigen and activity (555% and 520%, respectively) and increased Factor VIII clotting activity (369%).¹¹ These findings support vascular endotheliopathy causing exocytosis of ULVWF and associated increase in Factor VIII causing microthrombotic disease/embolism.

COVID-19 clinical syndrome appears very much consistent with EA-VMTD presenting with ARDS and MODS as well as micro-macro-thrombotic complications, including peripheral ischemia/gangrene involving fingers and toes and skin necrosis.^8,12

We believe that an appropriate therapy may not be anticoagulation but should include antimicrothrombotic therapy targeting endotheliopathy and primary hemostasis in the early stages of the disease (platelet adhesion, activation, and aggregation; especially eULVWF) like recombinant CD59 (membrane attack complex inhibition factor [MACIF]), recombinant ADAMTS13, glycoprotein IIb/IIIa receptor blocker, therapeutic plasma exchange, and perhaps anticomplement therapy (in selected cases) and others; these need to be validated in clinical trials prior to clinical application.

Of note, ADAMTS13 is a zinc containing protease. We noted that zinc and calcium concentrations play a significant role (in vitro) in ADAMTS13 activity in citrated plasma and recombinant ADAMTS13 activity with no added chelators (recombinant ADAMTS13 activity can enhance up to 200-fold); whereas in high zinc concentrations, ADAMTS13 gets deactivated.¹³ We suggest this finding merits an urgent clinical trial since it appears to us as the best possible cost-effective treatment for COVID-19 microthrombotic complications.

In this view of clinical pathophysiology of sepsis in COVID-19, we would like to enlighten the relationship between endothelial pathogenesis of coronaviral sepsis and vascular microthrombotic disease and would urge the medical community to immediately explore appropriate therapeutic options.

For health care professionals, especially those in the epicenters of the pandemic, among the most distressing aspects of this first wave of COVID-19 has been the absence of any drug to treat the virus. The practitioners on the frontlines have confronted repeated surges of critically ill and dying patients without any effective treatment to offer, resulting in feelings of hopelessness, guilt, moral distress, depression, and in some tragic cases, suicide.²

On May 12th, the Centers of Disease Control and Prevention (CDC) released additional guidance on the antiviral medications that are the subject of this essay. The CDC may have updated its treatment guidelines in part to try and bring a measure of clinical reasoning and scientific order into the impassioned and politicized chaos that surrounded hydrocloroquine and remdesivir in the media.³

In this fourth installment of my series on pandemic ethics, we examine the desperate race for hope in the form of drug treatments for COVID-19. The race has been run faster than any in history thanks to biotechnology, genetic engineering, and artificial intelligence, although many experts believe it will still be a marathon rather than a sprint to a vaccine.⁴

The first editorial in this series provided a primer of the key differences between public health ethics and clinical ethics. Another crucial distinction is the far more pervasive and powerful influence of nonmedical factors in decision making, including political agendas, economic motives, journalistic hyperbole, and cultural biases and orientations. These competing interests make it even more challenging for scientists of integrity and health care institutions that are trying to uphold core values to make principled judgments about what is best for critically ill patients and the demoralized staff caring for them. In the remainder of this column, I will trace the dynamics of these forces as they impact the use of 2 drugs in federal practice: hydroxychloroquine and remdesivir.

The trajectory of hydroxychloroquine has been a political and medical roller-coaster since the pandemic hit, as is evident in its US Department of Veterans Affairs (VA) ride. Various media outlets have reported that beginning about March 26, 2020, VA placed orders for up to $400,000 of the antimalarial drug hydroxychloroquine to be given to veterans hospitalized with COVID-19.⁵ The same day the VA Office of Inspector General (OIG) issued a report critical of VA pandemic readiness and its availability of hydroxychloroquine.⁶

The VA strongly refuted the report, objecting to the premise of the OIG investigation, which was to determine whether VA facilities had on hand a 14-day supply of chloroquine or hydroxychloroquine. “This is both inaccurate and irresponsible.” Noting that the drugs were still under investigation, the VA insisted that “No conclusions have been made on their effectiveness. To insist that a 14 days’ supply of these drugs is appropriate or not appropriate displays this dangerous lack of expertise on COVID-19 and Pandemic response.”⁶

In April, National Institutes of Health-sponsored researchers released data that hydroxychloroquine actually increased mortality among VA patients with COVID-19,⁷ leading veterans’ groups and the Senate minority leader to demand that VA cease to use hydroxychloroquine for COVID-19.⁸ As recently as May 15, the Associated Press reported that top VA officials have defended their use of the medication and stated they will not stop administering the medication for this indication.⁹ And VA is not alone, many other health care institutions are still prescribing hydroxychloroquine even amid scientific controversy about its putative benefits. In response to the growing awareness of the potential harms of the drug, the World Health Organization on May 25 announced it was halting all hydroxychloroquine trials.¹⁰ Why then do some physicians and health care providers continue to prescribe it? Because when nothing else stands between the patient and certain death even if there are known risks and uncertain benefits, some in health care feel morally obliged to use their best clinical judgment to help a patient.

Remdesivir’s fortunes both scientific and monetary also rose and fell on the tide of mixed results from studies. Military Times reported on March 10, 2020, that the US Army Medical Research and Development Command had made an agreement with Gilead Sciences, the manufacturer of remdesivir, to provide the medication to COVID-19-positive service members.¹¹ The antiviral had failed against Ebola and hepatitis but showed some efficacy for Middle East respiratory syndrome (MERS) and severe acute respiratory syndrome (SARS). On April 15, the Secretary of the Army announced that 2 COVID-19-positive soldiers had recovered after being given remdesivir.¹² In late April, the National Institute of Allergy and Infectious Diseases reported that in the scientific gold standard randomized placebo-controlled trial, remdesivir did speed the recovery of patients with advanced COVID-19. With the publication of the study in the prestigious New England Journal of Medicine on May 22, 2020, clearly the Army had bet on the right horse.¹³

This column has not been about quack cures and patent medicines that greed and ignorance breed in almost every American public health crisis—although these are by no means absent in this pandemic. This is about the serious endeavor of the top scientists and physicians in the country and, indeed, the world to discover a new medication or to repurpose an older pharmaceutical that is effective in the battle against COVID-19. The pressure on scientists and physicians to find a magic bullet in the battle against such an implacable enemy is unprecedented and unimaginable and can easily lead to sloppy science and ethical erosion.

In a utopia, pharmaceutical and vaccine research would be a matter of the discoveries of basic science trialed in the proof of concept of clinical care on a methodical, deliberate, and exacting timetable that balanced burdens and benefits.

In our current dystopia, science and medicine are only one of the many considerations affecting drug and vaccine development. As scientists and health care practitioners, we all experience a therapeutic imperative that we must heed with both caution and courage. Without caution we risk causing more harm than the disease we are fighting. Without courage we lose hope, the most potent antidote of all.

In our current dystopia, science and medicine are only one of the many considerations affecting drug and vaccine development. As scientists and health care practitioners, we all experience a therapeutic imperative that we must heed with both caution and courage. Without caution we risk causing more harm than the disease we are fighting. Without courage we lose hope, the most potent antidote of all.

The Lancet announced today that it has retracted a highly cited study that suggested hydroxychloroquine may cause more harm than benefit in patients with COVID-19. Hours later, the New England Journal of Medicine announced that it had retracted a second article by some of the same authors, also on heart disease and COVID-19.

The Lancet article, titled “Hydroxychloroquine or chloroquine with or without a macrolide for treatment of COVID-19: A multinational registry analysis” was originally published online May 22. The NEJM article, “Cardiovascular Disease, Drug Therapy, and Mortality in Covid-19” was initially published May 1.

Three authors of the Lancet article, Mandeep R. Mehra, MD, Frank Ruschitzka, MD, and Amit N. Patel, MD, wrote in a letter that the action came after concerns were raised about the integrity of the data, and about how the analysis was conducted by Chicago-based Surgisphere Corp and study coauthor Sapan Desai, MD, Surgisphere’s founder and CEO.

The authors asked for an independent third-party review of Surgisphere to evaluate the integrity of the trial elements and to replicate the analyses in the article.

“Our independent peer reviewers informed us that Surgisphere would not transfer the full dataset, client contracts, and the full ISO audit report to their servers for analysis, as such transfer would violate client agreements and confidentiality requirements,” the authors wrote.

Therefore, reviewers were not able to conduct the review and notified the authors they would withdraw from the peer-review process.

The Lancet said in a statement: “The Lancet takes issues of scientific integrity extremely seriously, and there are many outstanding questions about Surgisphere and the data that were allegedly included in this study. Following guidelines from the Committee on Publication Ethics and International Committee of Medical Journal Editors, institutional reviews of Surgisphere’s research collaborations are urgently needed.”

The authors wrote, “We can never forget the responsibility we have as researchers to scrupulously ensure that we rely on data sources that adhere to our high standards. Based on this development, we can no longer vouch for the veracity of the primary data sources. Due to this unfortunate development, the authors request that the paper be retracted.

“We all entered this collaboration to contribute in good faith and at a time of great need during the COVID-19 pandemic. We deeply apologize to you, the editors, and the journal readership for any embarrassment or inconvenience that this may have caused.”

In a similar, if briefer, note, the authors requested that the New England Journal of Medicine retract the earlier article as well. The retraction notice on the website reads: “Because all the authors were not granted access to the raw data and the raw data could not be made available to a third-party auditor, we are unable to validate the primary data sources underlying our article, ‘Cardiovascular Disease, Drug Therapy, and Mortality in Covid-19.’ We therefore request that the article be retracted. We apologize to the editors and to readers of the Journal for the difficulties that this has caused.”

Both journals had already published “Expression of Concern” notices about the articles. The expression of concern followed an open letter, endorsed by more than 200 scientists, ethicists, and clinicians and posted on May 28, questioning the data and ethics of the study.

Background: A small proportion of patients accounts for a large proportion of hospital use and readmissions. As hospitals and hospitalists focus efforts to improve transitions of care, there is a paucity of data that incorporates patients’ perspectives into the design of these programs.

A research coordinator conducted one-on-one semistructured interviews. Each interview was recorded, transcribed, and then coded using a team-based approach; 26 patients completed the interview process. From the analysis, four major themes emerged: Major medical problems were universal but high hospital use onset varied; participants noted that fluctuations in their course were often related to social, economic, and psychological stressors; onset and progression of episodes seemed uncontrollable and unpredictable; participants preferred to avoid hospitalization and sought care when attempts at self-management failed. The major limitation of this study was the small sample size located at one medical center, creating a data pool that is potentially not generalizable to other medical centers. These findings, however, are an important reminder to focus our interventions with patients’ needs and perceptions in mind.

Bottom line: Frequently hospitalized patients have insights into factors contributing to their high hospital use. Engaging patients in this discussion can enable us to create sustainable patient-centered programs that avoid rehospitalization.

COVID-19 infection is associated with a high risk for mortality in heart transplant (HT) recipients, a new case series suggests.

Investigators looked at data on 28 patients with a confirmed diagnosis of COVID-19 who received a HT between March 1, 2020, and April 24, 2020 and found a case-fatality rate of 25%.

“The high case fatality in our case series should alert physicians to the vulnerability of heart transplant recipients during the COVID-19 pandemic,” senior author Nir Uriel, MD, MSc, professor of medicine at Columbia University, New York, said in an interview.

“These patients require extra precautions to prevent the development of infection,” said Dr. Uriel, who is also a cardiologist at New York Presbyterian/Columbia University Irving Medical Center.

The study was published online May 13 in JAMA Cardiology.
 

Similar presentation

HT recipients can have several comorbidities after the procedure, including hypertension, diabetes, cardiac allograft vasculopathy, and ongoing immunosuppression, all of which can place them at risk for infection and adverse outcomes with COVID-19 infection, the authors wrote.

The researchers therefore embarked on a case series looking at 28 HT recipients with COVID-19 infection (median age, 64.0 years; interquartile range, 53.5-70.5; 79% male) to “describe the outcomes of recipients of HT who are chronically immunosuppressed and develop COVID-19 and raise important questions about the role of the immune system in the process.”

The median time from HT to study period was 8.6 (IQR, 4.2-14.5) years. Most patients had numerous comorbidities.

Medscape.com

No protective effect

Twenty-two patients (79%) required admission to the hospital, seven of whom (25%) required admission to the ICU and mechanical ventilation.

Despite the presence of immunosuppressive therapy, all patients had significant elevation of inflammatory biomarkers (median peak high-sensitivity C-reactive protein [hs-CRP], 11.83 mg/dL; IQR, 7.44-19.26; median peak interleukin [IL]-6, 105 pg/mL; IQR, 38-296).

Three-quarters had myocardial injury, with a median high-sensitivity troponin T of 0.055 (0.0205 - 0.1345) ng/mL.

Treatments of COVID-19 included hydroxychloroquine (18 patients; 78%), high-dose corticosteroids (eight patients; 47%), and IL-6 receptor antagonists (six patients; 26%).

Moreover, during hospitalization, mycophenolate mofetil was discontinued in most (70%) patients, and one-quarter had a reduction in their calcineurin inhibitor dose.

“Heart transplant recipients generally require more intense immunosuppressive therapy than most other solid organ transplant recipients, and this high baseline immunosuppression increases their propensity to develop infections and their likelihood of experiencing severe manifestations of infections,” Dr. Uriel commented.

“With COVID-19, in which the body’s inflammatory reaction appears to play a role in disease severity, there has been a question of whether immunosuppression may offer a protective effect,” he continued.

“This case series suggests that this is not the case, although this would need to be confirmed in larger studies,” he said.
 

Low threshold

Among the 22 patients who were admitted to the hospital, half were discharged home and four (18%) were still hospitalized at the end of the study.

Of the seven patients who died, two died at the study center, and five died in an outside institution.

“In the HT population, social distancing (or isolation), strict use of masks when in public, proper handwashing, and sanitization of surfaces are of paramount importance in the prevention of COVID-19 infection,” Dr. Uriel stated.

“In addition, we have restricted these patients’ contact with the hospital as much as possible during the pandemic,” he said.

However, “there should be a low threshold to hospitalize heart transplant patients who develop infection with COVID-19. Furthermore, in our series, outcomes were better for patients hospitalized at the transplant center; therefore, strong consideration should be given to transferring HT patients when hospitalized at another hospital,” he added.

The authors emphasized that COVID-19 patients “will require ongoing monitoring in the recovery phase, as an immunosuppression regimen is reintroduced and the consequences to the allograft itself become apparent.”
 

Vulnerable population

Commenting on the study, Mandeep R. Mehra, MD, MSc, William Harvey Distinguished Chair in Advanced Cardiovascular Medicine at Brigham and Women’s Hospital, Boston, suggested that “in epidemiological terms, [the findings] might not look as bad as the way they are reflected in the paper.”

Given that Columbia is “one of the larger heart transplant centers in the U.S., following probably 1,000 patients, having only 22 out of perhaps thousands whom they transplanted or are actively following would actually represent a low serious infection rate,” said Dr. Mehra, who is also the executive director of the Center for Advanced Heart Disease at Brigham and Women’s Hospital and a professor of medicine at Harvard Medical School, also in Boston.

“We must not forget to emphasize that, when assessing these case fatality rates, we must look at the entire population at risk, not only the handful that we were able to observe,” explained Dr. Mehra, who was not involved with the study.

Moreover, the patients were “older and had comorbidities, with poor underlying kidney function and other complications, and underlying coronary artery disease in the transplanted heart,” so “it would not surprise me that they had such a high fatality rate, since they had a high degree of vulnerability,” he said.

Dr. Mehra, who is also the editor-in-chief of the Journal of Heart and Lung Transplantation, said that the journal has received manuscripts still in the review process that suggest different fatality rates than those found in the current case series.

However, he acknowledged that, because these are patients with serious vulnerability due to underlying heart disease, “you can’t be lackadaisical and need to do everything to decrease this vulnerability.”

The authors noted that, although their study did not show a protective effect from immunosuppression against COVID-19, further studies are needed to assess each individual immunosuppressive agent and provide a definitive answer.

The study was supported by a grant to one of the investigators from the National Heart, Lung, and Blood Institute. Dr. Uriel reports no relevant financial relationships. The other authors’ disclosures are listed in the publication. Dr. Mehra reports no relevant financial relationships.

Here are the stories our MDedge editors across specialties think you need to know about today:

Could COVID-19 worsen gambling problems?

Take isolation, add excess available time and anxiety about illness or finances and you get the potential to increase problem gambling behaviors during the COVID-19 pandemic. A call to action, recently published in the Journal of Addiction Medicine, says it’s essential to gather data and supply guidance on this issue. “People are likely to be experiencing stress at levels they haven’t experienced previously,” said coauthor Marc N. Potenza, MD, PhD, of Yale University, New Haven, Conn. While multiple factors can contribute to addictive behaviors, “with respect to the pandemic, one concern is that so-called negative reinforcement motivations – engaging in an addictive behavior to escape from depressed or negative mood states – may be a driving motivation for a significant number of people during this time,” he said.

Food allergies in children are less frequent than expected

Food allergies appear to be less common than previously reported among 6- to 10-year-olds in Europe, according to a recent study. Prevalance ranged from a low of 1.4% to a high of 3.8%, both of which are “considerably lower” than the 16% rate based on parental reports of symptoms such as rash, itching, or diarrhea, Linus Grabenhenrich, MD, MPH, and colleagues reported in Allergy. The most commonly reported allergies were to peanuts and hazelnuts, with a prevalence of just over 5% for both.

William G. Wilkoff, MD, grew up in a family that didn’t embrace hugging, but as a small-town pediatrician he warmed up to the concept so much that he would frequently hug a passing acquaintance at the grocery store. That’s something he misses in the current environment and that he doesn’t expect will return. “[N]early every week I encounter one or two people with whom I have a long and sometimes emotionally charged relationship,” Dr. Wilkoff wrote in a column on MDedge. “Nurses with whom I sweated over difficult delivery room resuscitations. Parents for whom their anxiety was getting in the way of their ability to parent. Parents and caregivers of complex multiply disabled children who are now adults. Peers who have lost a spouse or a child. I’m sure you have your own list of people who send off that we-need-to-hug spark.” Read more.

Identifying structural lesions of axial spondyloarthritis

What constitutes a structural lesion of the sacroiliac joints on MRI that’s indicative of axial spondyloarthritis (axSpA) has long been a matter of conjecture, but the Assessment of SpondyloArthritis International Society (ASAS) MRI Working Group has developed new definitions that show a high degree of specificity in identifying such lesions in the disease. “Previous studies have described structural lesions in different ways, precluding meaningful comparisons between studies,” Walter P. Maksymowych, MD, said at the annual European Congress of Rheumatology, held online this year due to COVID-19. “The ASAS MRI group has generated updated consensus lesion definitions that describe each of the MRI lesions in the sacroiliac joint. These definitions have been validated by seven expert readers from the ASAS MRI group on MRI images from the ASAS classification cohort.” Read more.

Could COVID-19 worsen gambling problems?

Take isolation, add excess available time and anxiety about illness or finances and you get the potential to increase problem gambling behaviors during the COVID-19 pandemic. A call to action, recently published in the Journal of Addiction Medicine, says it’s essential to gather data and supply guidance on this issue. “People are likely to be experiencing stress at levels they haven’t experienced previously,” said coauthor Marc N. Potenza, MD, PhD, of Yale University, New Haven, Conn. While multiple factors can contribute to addictive behaviors, “with respect to the pandemic, one concern is that so-called negative reinforcement motivations – engaging in an addictive behavior to escape from depressed or negative mood states – may be a driving motivation for a significant number of people during this time,” he said.

The World Health Organization defines malnutrition as deficiencies, excesses, or imbalances in an individual’s intake of energy and/or nutrients.¹ This review will focus on undernutrition, which may result from macronutrient or micronutrient deficiencies. Undernutrition in the hospitalized patient is a common yet underrecognized phenomenon, with an estimated prevalence of 20% to 50% worldwide.² Malnutrition is an independent risk factor for patient morbidity and mortality and has been associated with increased health care costs.³ Nutritional deficiencies may arise from inadequate nutrient intake, abnormal nutrient absorption, or improper nutrient utilization.⁴ Unfortunately, no standardized algorithm for screening and diagnosing patients with malnutrition exists, making early physical examination findings of utmost importance. Herein, we present a review of acquired nutritional deficiency dermatoses in the inpatient setting.

Protein-Energy Malnutrition

Protein-energy malnutrition (PEM) refers to a set of related disorders that include marasmus, kwashiorkor (KW), and marasmic KW. These conditions frequently are seen in developing countries but also have been reported in developed nations.⁵ Marasmus occurs from a chronic deficiency of protein and calories. Decreased insulin production and unopposed catabolism result in sarcopenia and loss of bone and subcutaneous fat.⁶ Affected patients include children who are less than 60% ideal body weight (IBW) without edema or hypoproteinemia.⁷ Kwashiorkor is the edematous form of PEM that develops from isolated protein deficiency, resulting in edema, diarrhea, and immunosuppression.⁶ Micronutrient deficiencies, oxidative stress, slow protein catabolism, and excess antidiuretic hormone have been proposed as potential drivers of KW.⁸ Kwashiorkor affects children between 60% and 80% IBW. Marasmic KW has features of both diseases, including children who are less than 60% IBW but with associated edema and/or hypoproteinemia.⁹

Although PEM is uncommon in adults, hospitalized patients carry many predisposing risk factors, including infections, malabsorptive conditions, psychiatric disease, and chronic illness (eTable). Patients with chronic infections present with findings consistent with marasmic KW due to lean body mass loss.

Zinc Deficiency

Zinc is an essential trace element that provides regulatory, structural, and catalytic functions across multiple biochemical pathways⁶ and serves as an enzymatic cofactor and key component for numerous transcription factors.¹⁷ Zinc is derived from food sources, and its concentration correlates with protein content.¹⁸ Zinc is found in both animal and plant-based proteins, albeit with a lower oral bioavailability in the latter. Zinc deficiency may be inherited or acquired. Primary acrodermatitis enteropathica is an autosomal-recessive disorder of the solute carrier family 39 member 4 gene, SLC39A4 (encodes zinc transporter ZIP4 on enterocytes); the result is abnormal zinc absorption from the small intestine.¹⁸

Acquired zinc deficiency occurs from decreased dietary zinc intake, impaired intestinal zinc absorption, excessive zinc elimination, or systemic states of high catabolism or low albumin (eTable). Total parenteral nutrition–associated deficiency has arisen when nutritional formulations did not contain trace elements during national shortages or when prolonged TPN was not anticipated and trace elements were removed.¹⁹ Zinc levels may already be low in patients with chronic illness or inflammation, so even a short period on TPN can precipitate deficiency.^18,19 Diets high in phytate may result in zinc deficiency, as phytate impairs intestinal zinc absorption.²⁰ Approximately 15% of patients with inflammatory bowel disease experienced zinc deficiency worldwide.²¹ In Crohn disease, zinc deficiency has been associated with active intestinal inflammation, increased risk for hospitalization, surgeries, and disease-related complications.^22,23

Medications such as antiepileptics, antimetabolites, or penicillamine may induce zinc deficiency, highlighting the importance of medication review for hospitalized patients (eTable). Catabolic states, frequently encountered in hospitalized patients, increase the risk for zinc deficiency.²⁴ Patients with necrolytic migratory erythema (associated with pancreatic glucagonomas) often experience low serum zinc levels.²⁵

The skin is the third most zinc-abundant tissue in the human body. Within keratinocytes, zinc is critical to normal proliferation and suppression of inflammation.¹⁷ Zinc also plays an important role in cutaneous immune function.²⁶ Zinc deficiency presents with sharply demarcated, flaccid pustules and bullae that erode into scaly, pink, eczematous or psoriasiform plaques. Lesions are found preferentially in acral and periorificial sites, often with crusting and exudate. The groin and flexural surfaces may be affected. Erosions often become secondarily impetiginized. Other cutaneous findings include angular cheilitis, stomatitis, glossitis, paronychia, onychodystrophy, generalized alopecia, and delayed wound healing.²⁶ Histopathology of skin lesions is characterized by granular layer loss, epidermal pallor, confluent parakeratosis, spongiosis, dyskeratosis, and psoriasiform hyperplasia.²⁷ Acquired bullous acrodermatitis enteropathica has been reported as a histologic mimicker of pemphigus foliaceous in patients on TPN.²⁸

Diagnosis of zinc deficiency is made by measuring plasma zinc levels. Fasting levels should be drawn in the morning, as they can fluctuate based on the time of day, stress levels, or inflammation.⁶ Sample hemolysis and anticoagulants high in zinc may falsely elevate plasma zinc. A normal zinc level is greater than 70 µg/dL; however, normal levels do not rule out deficiency.¹⁸ Measurement of zinc-dependent enzymes, such as alkaline phosphatase, can be a quick way to assess zinc status. Serum albumin also should be measured; because zinc is carried by albumin in the blood, hypoalbuminemia may result in secondary zinc deficiency.¹⁸

Zinc replacement therapy is largely through oral supplementation and should start at 0.5 to 2.0 mg/kg/d in adults with acquired disease.^29,30 Zinc sulfate is the most affordable and is the supplement of choice, with 50 mg of elemental zinc per 220 mg of zinc sulfate (~23% elemental zinc).³¹ Alternative zinc salts, such as zinc gluconate (13% elemental zinc), may be used. Patients with malabsorptive disorders often require parenteral supplementation.³² Clinical symptoms often will resolve within 1 to 2 weeks of supplementation.²⁹ In patients with primary acrodermatitis enteropathica, lifelong supplementation with 3 mg/kg/d elemental zinc should occur.⁶ Calcium and folate may reduce zinc absorption, while zinc supplementation can interfere with copper and iron absorption.³³

Iron Deficiency

Iron is an essential component of the hemoglobin molecule. Iron homeostasis and metabolism are tightly regulated processes that drive erythropoiesis. Only 5% to 10% of dietary iron is absorbed through nutrition, while the remainder is recycled from red cell breakdown. Both normal iron levels and iron deficiency (ID) are defined by age and gender.³⁴ Iron-deficiency anemia (IDA) is one of the most common cause-specific anemias worldwide.³⁵

Fatigue is the most common and earliest symptom of ID. In a single study, pallor was predictive of anemia in hospitalized patients; however, absence of pallor did not rule out anemia.³⁴ Dyspnea on exertion, tachycardia, dysphagia, and pica also may be reported. Cutaneous manifestations include koilonychia (Figure 2), glossitis, pruritus, angular cheilitis, and telogen effluvium. Plummer-Vinson syndrome is characterized by microcytic anemia, glossitis, and dysphagia.

Iron deficiency can be present despite a normal hemoglobin level. Serum ferritin and percentage transferrin saturation are key to early identification of IDA.³⁵ Ferritin levels lower than 30 µg/L confirm the diagnosis. Decreased transferrin saturation and increased total iron binding capacity aid in the diagnosis of IDA. Serum ferritin is an acute-phase reactant, and levels may be falsely elevated in the setting of inflammation or infection.

Essential Fatty Acid Deficiency

Essential fatty acids (EFAs) including linoleic and α-linolenic acid cannot be synthesized by the human body and must be obtained through diet (mostly plant oils). Essential fatty acids have various functions, including maintaining phospholipid membrane integrity, forming prostaglandins and leukotrienes, and storing energy.⁴⁰ Essential fatty acids are important in the structure and function of the stratum corneum and are crucial in maintaining epidermal barrier function.⁴¹ Increased epidermal permeability and transepidermal water loss may be the first signs of EFA deficiency (EFAD).⁴²

The cutaneous manifestations of EFAD include xerosis, weeping eczematous plaques, and erosions in intertriginous sites. The lesions may progress to widespread desquamation and erythema. With time, the skin can become thick and leathery. Alopecia may occur, and hair may depigment.⁷ Additional findings include poor wound healing and increased susceptibility to infections.^43,44

Essential fatty acid deficiency may occur when dietary fat intake is severely restricted or in malabsorptive states.^45,46 It develops in patients on prolonged TPN, typically when receiving fat-restricted nutrition,^47,48 as occurs in hypertriglyceridemia.⁴⁷ Essential fatty acid deficiency has developed in patients on TPN containing EFAs,⁴⁷ as the introduction of novel intravenous lipid emulsions has resulted in varying proportions of EFA.⁴⁰ Premature neonates are particularly at risk for EFAD.⁴⁹

The diagnosis of EFAD involves the measurement of the triene to tetraene ratio. A ratio of more than 0.2 suggests EFAD, but the clinical signs are not seen until the ratio is over 0.4.⁴⁰ Low plasma levels of linoleic, linolenic, and arachidonic acids also are seen. Elevated liver function tests are supportive of the diagnosis. Biochemical findings typically are seen before cutaneous manifestations.⁴⁰

Treatment of EFAD includes topical, oral, or intravenous replacement of EFAs. Improvement of EFAD with the application of topical linoleic acid to the skin has been reported.⁵⁰ Patients receiving TPN should undergo assessment of parenteral lipid emulsion to ensure adequate fatty acid composition.

Vitamin A Deficiency

Vitamin A (retinol) is a fat-soluble vitamin that plays a critical role in keratinization, epithelial proliferation, and cellular differentiation.⁶ Vitamin A is found in animal products as retinyl esters and in plants as beta-carotene. Vitamin A has 2 clinically important forms: all-trans retinoic acid and 11-cis-retinal. All-trans retinoic acid is involved in cellular differentiation and regulating gene transcription, while 11-cis-retinal is key to rhodopsin generation required for vision. Vitamin A deficiency presents with early ophthalmologic findings, specifically nyctalopia, or delayed adaptation to the dark.⁵¹ Xerophthalmia, abnormal conjunctival keratinization, and Bitot spots subsequently develop and may progress to corneal ulceration and blindness.⁶

Vitamin A deficiency manifests in the skin as follicular hyperkeratosis, or phrynoderma. Notably, numerous other micronutrient deficiencies may result in phrynoderma. Clinically, multiple pigmented keratotic papules of various sizes, many with a central keratinous plug, are distributed symmetrically on the extensor elbows, knees, shoulders, buttocks, and extremities. The skin surrounding these lesions may be scaly and hyperpigmented.⁵² Generalized xerosis without preceding nyctalopia has been reported.⁵³ Accompanying pityriasis alba may develop.⁵² Lesions on the face may mimic acne, while lesions on the extremities may simulate a perforating disorder. Histopathology of phrynoderma reveals epidermal hyperkeratosis, follicular hyperkeratosis, and follicular plugging.⁵²

Vitamin A deficiency can be diagnosed by measuring serum retinol levels, with levels lower than 20 µg/dL being diagnostic of deficiency.⁵⁶ Decreased serum retinol in patients hospitalized with flaring irritable bowel disorder has been repeatedly reported.^57-59 Notably, serum retinol concentration does not decline until liver reserves of vitamin A are nearing exhaustion.³³

The US Food and Drug Administration requires manufacturers to list retinol activity equivalents on labels. One international unit of retinol is equivalent to 0.3 µg of retinol activity equivalents.⁶⁰ The treatment of vitamin A deficiency involves high-dose oral supplementation when possible.⁶¹ Although dependent on age, the treatment dose for most adults with vitamin A deficiency is 3000 µg (10,000 IU) once daily.

Phrynoderma has been specifically treated with salicylic acid ointment 3% and intramuscular vitamin A.⁶² Topical urea cream also may treat phrynoderma.⁶³

Vitamin B₂

Vitamin B₂ (riboflavin) is absorbed in the small intestine and converted into 2 biologically active forms—flavin adenine dinucleotide and flavin mononucleotide—which serve as cofactors in metabolic and oxidation-reduction reactions. Malabsorptive disorders and bowel resection can lead to riboflavin deficiency.⁶⁴ Other at-risk populations include those with restrictive diets,⁶⁵ psychiatric illness, or systemic illness (eTable). Riboflavin can be degraded by light (deficiency has been reported after phototherapy for neonatal jaundice⁶⁶) and following boric acid ingestion.⁶⁷ Medications, including long-term treatment with antiepileptics, may lead to riboflavin deficiency.⁶⁸

Riboflavin is critical to maintaining collagen production. Riboflavin deficiency may manifest clinically with extensive seborrheiclike dermatitis,⁴⁴ intertrigolike dermatitis,⁶⁹ or oral-ocular-genital syndrome.⁷⁰ Angular cheilitis may accompany an atrophic tongue that is deep red in color. The scrotum is characteristically involved in men, with confluent dermatitis extending onto the thighs and sparing the midline. Red papules and painful fissures may develop. Balanitis and phimosis have been reported. Testing for riboflavin deficiency should be considered in patients with refractory seborrheic dermatitis.

Riboflavin stores are assessed by the erythrocyte glutathione reductase activity coefficient.⁴⁴ A level of 1.4 or higher is consistent with deficiency. Serum riboflavin levels, performed after a 12-hour fast, may support the diagnosis but are less sensitive. Patients with glucose-6-phosphate deficiency cannot be assessed via the erythrocyte glutathione reductase activity coefficient and may instead require evaluation of 24-hour urine riboflavin level.⁴⁴

Vitamin B₃

Vitamin B₃ (niacin, nicotinamide, nicotinic acid) is found in plant and animal products or can be derived from its amino acid precursor tryptophan. Niacin deficiency results in pellagra, characterized by dermatitis, dementia, and diarrhea.⁷¹ The most prominent feature is a symmetrically distributed photosensitive dermatitis of the face, neck (called Casal necklace)(Figure 3), chest, dorsal hands, and extensor arms. The eruption may begin with erythema, vesicles, or bullae (wet pellagra) and evolve into thick, hyperpigmented, scaling plaques.⁷¹ The skin may take on a copper tone and become atrophic.⁷² Dull erythema with overlying yellow powdery scale (called sulfur flakes) at follicular orifices has been described on the nasal bridge.⁷³

Causes of niacin deficiency include malabsorptive conditions, malignancy (including carcinoid tumors), parenteral nutrition, psychiatric disease,^74,75 and restrictive diets (eTable).⁷⁶ Carcinoid tumors divert tryptophan to serotonin resulting in niacin deficiency.⁷⁷

The diagnosis of niacin deficiency is based on clinical findings and response to supplementation.⁷⁵ Low niacin urinary metabolites (N-methylnicotinamide and 2-pyridone) may aid in diagnosis.⁶ Treatment generally includes oral nicotinamide 100 mg every 6 hours; the dose can then be tapered to 50 mg every 8 to 12 hours until symptoms resolve. Severe deficiency may require parenteral nicotinamide 1 g 3 to 4 times daily.⁷⁵

Vitamin B₆

Vitamin B₆ (pyridoxine, pyridoxamine, pyridoxal) is found in whole grains and plant and animal products. Vitamin B₆ functions as a coenzyme in many metabolic pathways and is involved in the conversion of tryptophan to niacin.⁴⁴ Absorption requires hydrolysis by intestinal phosphates and transport to the liver for rephosphorylation prior to release in active form.⁶

Cutaneous findings associated with vitamin B₆ deficiency include periorificial and perineal seborrheic dermatitis,⁷⁸ angular stomatitis, and cheilitis, with associated burning, redness, and tongue edema.⁶ Vitamin B₆ deficiency is a rarely reported cause of burning mouth syndrome.⁷⁹ Because vitamin B₆ is involved in the conversion of tryptophan to niacin, deficiency also may present with pellagralike findings.⁷⁰ Other clinical symptoms are outlined in the eTable.^80,81

Conditions that increase risk for vitamin B₆ deficiency are highlighted in the eTable and include malabsorptive disorders; psychiatric illness⁸²; and chronic disease, especially end-stage renal disease.⁸³ Vitamin B₆ deficiency associated with chronic alcohol use is due to both inadequate vitamin B₆ intake as well as reduced hepatic storage.⁷⁸ Medications such as isoniazid, hydralazine, and oral contraceptives may decrease vitamin B₆ levels (eTable).⁸²

Vitamin B₆ can be measured in the plasma as pyridoxal 5′-phosphate. Plasma concentrations of less than 20 nmol/L are suggestive of deficiency.⁸² Indirect tests include tryptophan and methionine loading.⁶ The treatment of vitamin B₆ deficiency is determined by symptom severity. Recommendations for oral supplementation range from 25 to 600 mg daily.⁸² Symptoms typically improve on 100 mg daily.⁶

Vitamins B₉ and B₁₂

Deficiencies of vitamins B₉ (folic acid, folate) and B₁₂ (cobalamin) have similar clinical presentations. Folate is essential in the metabolism of amino acids, purines, and pyrimidines.⁶ Cobalamin, found in animal products, is a cofactor for methionine synthase and methylmalonyl-CoA mutase.⁸⁴ Megaloblastic anemia is the main finding in folate or cobalamin deficiency. Neurologic findings only accompany cobalamin deficiency. Risk factors for folate deficiency include malabsorptive conditions,⁶ chronic alcohol use,⁸⁵ and antifolate medication use (eTable).⁶

Cobalamin absorption requires gastric acid and intrinsic factor binding in the duodenum. Deficiency may occur from strict diets, psychiatric illness, old age,⁸⁶ decreased gastric acid secretion,⁸⁷ abnormal intrinsic factor function, or intestinal infections.⁶

Generalized cutaneous hyperpigmentation may be the first manifestation of vitamins B₉ and B₁₂ deficiency.⁸⁸ Typically accentuated in acral creases and the oral cavity, pigmentation may mimic Addison disease. Hair depigmentation and linear streaking of the nails are reported.⁸⁴ The tongue becomes painful and red with atrophy of the filiform papillae (Hunter glossitis).⁷⁸ Linear lesions on the tongue and hard palate may serve as an early sign of cobalamin deficiency.⁸⁹

Folate deficiency is diagnosed by measuring the plasma folate level; coincidental cobalamin deficiency should be excluded. Deficiency is managed with oral supplementation (when possible) with 1 to 5 mg of folate daily.⁶ Cobalamin deficiency is based on low serum levels (<150 pg/mL is diagnostic).⁸⁶ Cobalamin deficiency may take years to develop, as vitamin B₁₂ exists in large body stores.⁶ Serum methylmalonic acid may be elevated in patients with clinical features but normal-low serum vitamin B₁₂ level.⁸⁶ Treatment of vitamin B₁₂ deficiency is with oral (2 mg once daily) or parenteral (1 mg every 4 weeks then maintained at once monthly) cyanocobalamin. For patients with neurologic symptoms, intramuscular injection should be given.⁸⁶ The underlying cause of deficiency must be elucidated and treated.

Vitamin C Deficiency

Vitamin C (ascorbic acid) is an essential cofactor for the hydroxylation of proline and lysine residues in collagen synthesis. Plant-based foods are the main dietary source of vitamin C, and deficiency presents clinically as scurvy. Cutaneous findings include follicular hyperkeratosis, perifollicular petechiae, and curled hair shafts (corkscrew hairs)(Figure 4). Ecchymoses of the lower extremities, forearms, and abdomen may be seen. Nodules representing intramuscular and subcutaneous hemorrhage can be present.⁹⁰ Woody edema may mimic cellulitis, while lower extremity hemorrhage may mimic vasculitis. Gingival hyperplasia, hemorrhage, and edema may occur,⁹⁰ along with linear splinter hemorrhages.⁹¹

Hypovitaminosis C has been routinely demonstrated in hospitalized patients.⁹² Scurvy may occur in patients on strict diets,⁹³ chronic alcohol use,⁹⁴ psychiatric illness,⁹⁵ or gastrointestinal tract disease (eTable).^96-99 Those with low socioeconomic status⁷⁰ or dementia¹⁰⁰ as well as the elderly also are at risk.¹⁰¹ Scurvy has developed in patients with iron overload and those who are on hemodialysis⁴⁴ as well as in association with nilotinib use.¹⁰² Patients with chronic mucous membrane graft-vs-host disease may exhibit vitamin C deficiency.¹⁰³

Scurvy is a clinical diagnosis. Vitamin C levels normalize quickly with supplementation. Cutaneous biopsy will exhibit follicular hyperkeratosis, perifollicular hemorrhage, and fibrosis.⁹¹

Oral ascorbic acid supplementation should be initiated at 500 to 1000 mg daily in adults.¹⁰⁴ The cause of deficiency should be identified, and further supplementation should be decided based on patient risk factors. Lifestyle modifications, such as cessation of smoking and chronic alcohol use, is recommended. The diagnosis of scurvy should prompt workup for additional nutrient deficiencies.

Final Thoughts

Dermatologists play an important role in the early recognition of nutritional deficiencies, as cutaneous manifestations often are the first clue to diagnosis. Nutritional deficiencies are common yet underrecognized in the hospitalized patient and serve as an independent risk factor for patient morbidity and mortality.³ Awareness of the cutaneous manifestations of undernutrition as well as the risk factors for nutritional deficiency may expedite diagnosis and supplementation, thereby improving outcomes for hospitalized patients.

The World Health Organization defines malnutrition as deficiencies, excesses, or imbalances in an individual’s intake of energy and/or nutrients.¹ This review will focus on undernutrition, which may result from macronutrient or micronutrient deficiencies. Undernutrition in the hospitalized patient is a common yet underrecognized phenomenon, with an estimated prevalence of 20% to 50% worldwide.² Malnutrition is an independent risk factor for patient morbidity and mortality and has been associated with increased health care costs.³ Nutritional deficiencies may arise from inadequate nutrient intake, abnormal nutrient absorption, or improper nutrient utilization.⁴ Unfortunately, no standardized algorithm for screening and diagnosing patients with malnutrition exists, making early physical examination findings of utmost importance. Herein, we present a review of acquired nutritional deficiency dermatoses in the inpatient setting.

Protein-Energy Malnutrition

Protein-energy malnutrition (PEM) refers to a set of related disorders that include marasmus, kwashiorkor (KW), and marasmic KW. These conditions frequently are seen in developing countries but also have been reported in developed nations.⁵ Marasmus occurs from a chronic deficiency of protein and calories. Decreased insulin production and unopposed catabolism result in sarcopenia and loss of bone and subcutaneous fat.⁶ Affected patients include children who are less than 60% ideal body weight (IBW) without edema or hypoproteinemia.⁷ Kwashiorkor is the edematous form of PEM that develops from isolated protein deficiency, resulting in edema, diarrhea, and immunosuppression.⁶ Micronutrient deficiencies, oxidative stress, slow protein catabolism, and excess antidiuretic hormone have been proposed as potential drivers of KW.⁸ Kwashiorkor affects children between 60% and 80% IBW. Marasmic KW has features of both diseases, including children who are less than 60% IBW but with associated edema and/or hypoproteinemia.⁹

Although PEM is uncommon in adults, hospitalized patients carry many predisposing risk factors, including infections, malabsorptive conditions, psychiatric disease, and chronic illness (eTable). Patients with chronic infections present with findings consistent with marasmic KW due to lean body mass loss.

Zinc Deficiency

Zinc is an essential trace element that provides regulatory, structural, and catalytic functions across multiple biochemical pathways⁶ and serves as an enzymatic cofactor and key component for numerous transcription factors.¹⁷ Zinc is derived from food sources, and its concentration correlates with protein content.¹⁸ Zinc is found in both animal and plant-based proteins, albeit with a lower oral bioavailability in the latter. Zinc deficiency may be inherited or acquired. Primary acrodermatitis enteropathica is an autosomal-recessive disorder of the solute carrier family 39 member 4 gene, SLC39A4 (encodes zinc transporter ZIP4 on enterocytes); the result is abnormal zinc absorption from the small intestine.¹⁸

Acquired zinc deficiency occurs from decreased dietary zinc intake, impaired intestinal zinc absorption, excessive zinc elimination, or systemic states of high catabolism or low albumin (eTable). Total parenteral nutrition–associated deficiency has arisen when nutritional formulations did not contain trace elements during national shortages or when prolonged TPN was not anticipated and trace elements were removed.¹⁹ Zinc levels may already be low in patients with chronic illness or inflammation, so even a short period on TPN can precipitate deficiency.^18,19 Diets high in phytate may result in zinc deficiency, as phytate impairs intestinal zinc absorption.²⁰ Approximately 15% of patients with inflammatory bowel disease experienced zinc deficiency worldwide.²¹ In Crohn disease, zinc deficiency has been associated with active intestinal inflammation, increased risk for hospitalization, surgeries, and disease-related complications.^22,23

Medications such as antiepileptics, antimetabolites, or penicillamine may induce zinc deficiency, highlighting the importance of medication review for hospitalized patients (eTable). Catabolic states, frequently encountered in hospitalized patients, increase the risk for zinc deficiency.²⁴ Patients with necrolytic migratory erythema (associated with pancreatic glucagonomas) often experience low serum zinc levels.²⁵

The skin is the third most zinc-abundant tissue in the human body. Within keratinocytes, zinc is critical to normal proliferation and suppression of inflammation.¹⁷ Zinc also plays an important role in cutaneous immune function.²⁶ Zinc deficiency presents with sharply demarcated, flaccid pustules and bullae that erode into scaly, pink, eczematous or psoriasiform plaques. Lesions are found preferentially in acral and periorificial sites, often with crusting and exudate. The groin and flexural surfaces may be affected. Erosions often become secondarily impetiginized. Other cutaneous findings include angular cheilitis, stomatitis, glossitis, paronychia, onychodystrophy, generalized alopecia, and delayed wound healing.²⁶ Histopathology of skin lesions is characterized by granular layer loss, epidermal pallor, confluent parakeratosis, spongiosis, dyskeratosis, and psoriasiform hyperplasia.²⁷ Acquired bullous acrodermatitis enteropathica has been reported as a histologic mimicker of pemphigus foliaceous in patients on TPN.²⁸

Diagnosis of zinc deficiency is made by measuring plasma zinc levels. Fasting levels should be drawn in the morning, as they can fluctuate based on the time of day, stress levels, or inflammation.⁶ Sample hemolysis and anticoagulants high in zinc may falsely elevate plasma zinc. A normal zinc level is greater than 70 µg/dL; however, normal levels do not rule out deficiency.¹⁸ Measurement of zinc-dependent enzymes, such as alkaline phosphatase, can be a quick way to assess zinc status. Serum albumin also should be measured; because zinc is carried by albumin in the blood, hypoalbuminemia may result in secondary zinc deficiency.¹⁸

Zinc replacement therapy is largely through oral supplementation and should start at 0.5 to 2.0 mg/kg/d in adults with acquired disease.^29,30 Zinc sulfate is the most affordable and is the supplement of choice, with 50 mg of elemental zinc per 220 mg of zinc sulfate (~23% elemental zinc).³¹ Alternative zinc salts, such as zinc gluconate (13% elemental zinc), may be used. Patients with malabsorptive disorders often require parenteral supplementation.³² Clinical symptoms often will resolve within 1 to 2 weeks of supplementation.²⁹ In patients with primary acrodermatitis enteropathica, lifelong supplementation with 3 mg/kg/d elemental zinc should occur.⁶ Calcium and folate may reduce zinc absorption, while zinc supplementation can interfere with copper and iron absorption.³³

Iron Deficiency

Iron is an essential component of the hemoglobin molecule. Iron homeostasis and metabolism are tightly regulated processes that drive erythropoiesis. Only 5% to 10% of dietary iron is absorbed through nutrition, while the remainder is recycled from red cell breakdown. Both normal iron levels and iron deficiency (ID) are defined by age and gender.³⁴ Iron-deficiency anemia (IDA) is one of the most common cause-specific anemias worldwide.³⁵

Fatigue is the most common and earliest symptom of ID. In a single study, pallor was predictive of anemia in hospitalized patients; however, absence of pallor did not rule out anemia.³⁴ Dyspnea on exertion, tachycardia, dysphagia, and pica also may be reported. Cutaneous manifestations include koilonychia (Figure 2), glossitis, pruritus, angular cheilitis, and telogen effluvium. Plummer-Vinson syndrome is characterized by microcytic anemia, glossitis, and dysphagia.

Iron deficiency can be present despite a normal hemoglobin level. Serum ferritin and percentage transferrin saturation are key to early identification of IDA.³⁵ Ferritin levels lower than 30 µg/L confirm the diagnosis. Decreased transferrin saturation and increased total iron binding capacity aid in the diagnosis of IDA. Serum ferritin is an acute-phase reactant, and levels may be falsely elevated in the setting of inflammation or infection.

Essential Fatty Acid Deficiency

Essential fatty acids (EFAs) including linoleic and α-linolenic acid cannot be synthesized by the human body and must be obtained through diet (mostly plant oils). Essential fatty acids have various functions, including maintaining phospholipid membrane integrity, forming prostaglandins and leukotrienes, and storing energy.⁴⁰ Essential fatty acids are important in the structure and function of the stratum corneum and are crucial in maintaining epidermal barrier function.⁴¹ Increased epidermal permeability and transepidermal water loss may be the first signs of EFA deficiency (EFAD).⁴²

The cutaneous manifestations of EFAD include xerosis, weeping eczematous plaques, and erosions in intertriginous sites. The lesions may progress to widespread desquamation and erythema. With time, the skin can become thick and leathery. Alopecia may occur, and hair may depigment.⁷ Additional findings include poor wound healing and increased susceptibility to infections.^43,44

Essential fatty acid deficiency may occur when dietary fat intake is severely restricted or in malabsorptive states.^45,46 It develops in patients on prolonged TPN, typically when receiving fat-restricted nutrition,^47,48 as occurs in hypertriglyceridemia.⁴⁷ Essential fatty acid deficiency has developed in patients on TPN containing EFAs,⁴⁷ as the introduction of novel intravenous lipid emulsions has resulted in varying proportions of EFA.⁴⁰ Premature neonates are particularly at risk for EFAD.⁴⁹

The diagnosis of EFAD involves the measurement of the triene to tetraene ratio. A ratio of more than 0.2 suggests EFAD, but the clinical signs are not seen until the ratio is over 0.4.⁴⁰ Low plasma levels of linoleic, linolenic, and arachidonic acids also are seen. Elevated liver function tests are supportive of the diagnosis. Biochemical findings typically are seen before cutaneous manifestations.⁴⁰

Treatment of EFAD includes topical, oral, or intravenous replacement of EFAs. Improvement of EFAD with the application of topical linoleic acid to the skin has been reported.⁵⁰ Patients receiving TPN should undergo assessment of parenteral lipid emulsion to ensure adequate fatty acid composition.

Vitamin A Deficiency

Vitamin A (retinol) is a fat-soluble vitamin that plays a critical role in keratinization, epithelial proliferation, and cellular differentiation.⁶ Vitamin A is found in animal products as retinyl esters and in plants as beta-carotene. Vitamin A has 2 clinically important forms: all-trans retinoic acid and 11-cis-retinal. All-trans retinoic acid is involved in cellular differentiation and regulating gene transcription, while 11-cis-retinal is key to rhodopsin generation required for vision. Vitamin A deficiency presents with early ophthalmologic findings, specifically nyctalopia, or delayed adaptation to the dark.⁵¹ Xerophthalmia, abnormal conjunctival keratinization, and Bitot spots subsequently develop and may progress to corneal ulceration and blindness.⁶

Vitamin A deficiency manifests in the skin as follicular hyperkeratosis, or phrynoderma. Notably, numerous other micronutrient deficiencies may result in phrynoderma. Clinically, multiple pigmented keratotic papules of various sizes, many with a central keratinous plug, are distributed symmetrically on the extensor elbows, knees, shoulders, buttocks, and extremities. The skin surrounding these lesions may be scaly and hyperpigmented.⁵² Generalized xerosis without preceding nyctalopia has been reported.⁵³ Accompanying pityriasis alba may develop.⁵² Lesions on the face may mimic acne, while lesions on the extremities may simulate a perforating disorder. Histopathology of phrynoderma reveals epidermal hyperkeratosis, follicular hyperkeratosis, and follicular plugging.⁵²

Vitamin A deficiency can be diagnosed by measuring serum retinol levels, with levels lower than 20 µg/dL being diagnostic of deficiency.⁵⁶ Decreased serum retinol in patients hospitalized with flaring irritable bowel disorder has been repeatedly reported.^57-59 Notably, serum retinol concentration does not decline until liver reserves of vitamin A are nearing exhaustion.³³

The US Food and Drug Administration requires manufacturers to list retinol activity equivalents on labels. One international unit of retinol is equivalent to 0.3 µg of retinol activity equivalents.⁶⁰ The treatment of vitamin A deficiency involves high-dose oral supplementation when possible.⁶¹ Although dependent on age, the treatment dose for most adults with vitamin A deficiency is 3000 µg (10,000 IU) once daily.

Phrynoderma has been specifically treated with salicylic acid ointment 3% and intramuscular vitamin A.⁶² Topical urea cream also may treat phrynoderma.⁶³

Vitamin B₂

Vitamin B₂ (riboflavin) is absorbed in the small intestine and converted into 2 biologically active forms—flavin adenine dinucleotide and flavin mononucleotide—which serve as cofactors in metabolic and oxidation-reduction reactions. Malabsorptive disorders and bowel resection can lead to riboflavin deficiency.⁶⁴ Other at-risk populations include those with restrictive diets,⁶⁵ psychiatric illness, or systemic illness (eTable). Riboflavin can be degraded by light (deficiency has been reported after phototherapy for neonatal jaundice⁶⁶) and following boric acid ingestion.⁶⁷ Medications, including long-term treatment with antiepileptics, may lead to riboflavin deficiency.⁶⁸

Riboflavin is critical to maintaining collagen production. Riboflavin deficiency may manifest clinically with extensive seborrheiclike dermatitis,⁴⁴ intertrigolike dermatitis,⁶⁹ or oral-ocular-genital syndrome.⁷⁰ Angular cheilitis may accompany an atrophic tongue that is deep red in color. The scrotum is characteristically involved in men, with confluent dermatitis extending onto the thighs and sparing the midline. Red papules and painful fissures may develop. Balanitis and phimosis have been reported. Testing for riboflavin deficiency should be considered in patients with refractory seborrheic dermatitis.

Riboflavin stores are assessed by the erythrocyte glutathione reductase activity coefficient.⁴⁴ A level of 1.4 or higher is consistent with deficiency. Serum riboflavin levels, performed after a 12-hour fast, may support the diagnosis but are less sensitive. Patients with glucose-6-phosphate deficiency cannot be assessed via the erythrocyte glutathione reductase activity coefficient and may instead require evaluation of 24-hour urine riboflavin level.⁴⁴

Vitamin B₃

Vitamin B₃ (niacin, nicotinamide, nicotinic acid) is found in plant and animal products or can be derived from its amino acid precursor tryptophan. Niacin deficiency results in pellagra, characterized by dermatitis, dementia, and diarrhea.⁷¹ The most prominent feature is a symmetrically distributed photosensitive dermatitis of the face, neck (called Casal necklace)(Figure 3), chest, dorsal hands, and extensor arms. The eruption may begin with erythema, vesicles, or bullae (wet pellagra) and evolve into thick, hyperpigmented, scaling plaques.⁷¹ The skin may take on a copper tone and become atrophic.⁷² Dull erythema with overlying yellow powdery scale (called sulfur flakes) at follicular orifices has been described on the nasal bridge.⁷³

Causes of niacin deficiency include malabsorptive conditions, malignancy (including carcinoid tumors), parenteral nutrition, psychiatric disease,^74,75 and restrictive diets (eTable).⁷⁶ Carcinoid tumors divert tryptophan to serotonin resulting in niacin deficiency.⁷⁷

The diagnosis of niacin deficiency is based on clinical findings and response to supplementation.⁷⁵ Low niacin urinary metabolites (N-methylnicotinamide and 2-pyridone) may aid in diagnosis.⁶ Treatment generally includes oral nicotinamide 100 mg every 6 hours; the dose can then be tapered to 50 mg every 8 to 12 hours until symptoms resolve. Severe deficiency may require parenteral nicotinamide 1 g 3 to 4 times daily.⁷⁵

Vitamin B₆

Vitamin B₆ (pyridoxine, pyridoxamine, pyridoxal) is found in whole grains and plant and animal products. Vitamin B₆ functions as a coenzyme in many metabolic pathways and is involved in the conversion of tryptophan to niacin.⁴⁴ Absorption requires hydrolysis by intestinal phosphates and transport to the liver for rephosphorylation prior to release in active form.⁶

Cutaneous findings associated with vitamin B₆ deficiency include periorificial and perineal seborrheic dermatitis,⁷⁸ angular stomatitis, and cheilitis, with associated burning, redness, and tongue edema.⁶ Vitamin B₆ deficiency is a rarely reported cause of burning mouth syndrome.⁷⁹ Because vitamin B₆ is involved in the conversion of tryptophan to niacin, deficiency also may present with pellagralike findings.⁷⁰ Other clinical symptoms are outlined in the eTable.^80,81

Conditions that increase risk for vitamin B₆ deficiency are highlighted in the eTable and include malabsorptive disorders; psychiatric illness⁸²; and chronic disease, especially end-stage renal disease.⁸³ Vitamin B₆ deficiency associated with chronic alcohol use is due to both inadequate vitamin B₆ intake as well as reduced hepatic storage.⁷⁸ Medications such as isoniazid, hydralazine, and oral contraceptives may decrease vitamin B₆ levels (eTable).⁸²

Vitamin B₆ can be measured in the plasma as pyridoxal 5′-phosphate. Plasma concentrations of less than 20 nmol/L are suggestive of deficiency.⁸² Indirect tests include tryptophan and methionine loading.⁶ The treatment of vitamin B₆ deficiency is determined by symptom severity. Recommendations for oral supplementation range from 25 to 600 mg daily.⁸² Symptoms typically improve on 100 mg daily.⁶

Vitamins B₉ and B₁₂

Deficiencies of vitamins B₉ (folic acid, folate) and B₁₂ (cobalamin) have similar clinical presentations. Folate is essential in the metabolism of amino acids, purines, and pyrimidines.⁶ Cobalamin, found in animal products, is a cofactor for methionine synthase and methylmalonyl-CoA mutase.⁸⁴ Megaloblastic anemia is the main finding in folate or cobalamin deficiency. Neurologic findings only accompany cobalamin deficiency. Risk factors for folate deficiency include malabsorptive conditions,⁶ chronic alcohol use,⁸⁵ and antifolate medication use (eTable).⁶

Cobalamin absorption requires gastric acid and intrinsic factor binding in the duodenum. Deficiency may occur from strict diets, psychiatric illness, old age,⁸⁶ decreased gastric acid secretion,⁸⁷ abnormal intrinsic factor function, or intestinal infections.⁶

Generalized cutaneous hyperpigmentation may be the first manifestation of vitamins B₉ and B₁₂ deficiency.⁸⁸ Typically accentuated in acral creases and the oral cavity, pigmentation may mimic Addison disease. Hair depigmentation and linear streaking of the nails are reported.⁸⁴ The tongue becomes painful and red with atrophy of the filiform papillae (Hunter glossitis).⁷⁸ Linear lesions on the tongue and hard palate may serve as an early sign of cobalamin deficiency.⁸⁹

Folate deficiency is diagnosed by measuring the plasma folate level; coincidental cobalamin deficiency should be excluded. Deficiency is managed with oral supplementation (when possible) with 1 to 5 mg of folate daily.⁶ Cobalamin deficiency is based on low serum levels (<150 pg/mL is diagnostic).⁸⁶ Cobalamin deficiency may take years to develop, as vitamin B₁₂ exists in large body stores.⁶ Serum methylmalonic acid may be elevated in patients with clinical features but normal-low serum vitamin B₁₂ level.⁸⁶ Treatment of vitamin B₁₂ deficiency is with oral (2 mg once daily) or parenteral (1 mg every 4 weeks then maintained at once monthly) cyanocobalamin. For patients with neurologic symptoms, intramuscular injection should be given.⁸⁶ The underlying cause of deficiency must be elucidated and treated.

Vitamin C Deficiency

Vitamin C (ascorbic acid) is an essential cofactor for the hydroxylation of proline and lysine residues in collagen synthesis. Plant-based foods are the main dietary source of vitamin C, and deficiency presents clinically as scurvy. Cutaneous findings include follicular hyperkeratosis, perifollicular petechiae, and curled hair shafts (corkscrew hairs)(Figure 4). Ecchymoses of the lower extremities, forearms, and abdomen may be seen. Nodules representing intramuscular and subcutaneous hemorrhage can be present.⁹⁰ Woody edema may mimic cellulitis, while lower extremity hemorrhage may mimic vasculitis. Gingival hyperplasia, hemorrhage, and edema may occur,⁹⁰ along with linear splinter hemorrhages.⁹¹

Hypovitaminosis C has been routinely demonstrated in hospitalized patients.⁹² Scurvy may occur in patients on strict diets,⁹³ chronic alcohol use,⁹⁴ psychiatric illness,⁹⁵ or gastrointestinal tract disease (eTable).^96-99 Those with low socioeconomic status⁷⁰ or dementia¹⁰⁰ as well as the elderly also are at risk.¹⁰¹ Scurvy has developed in patients with iron overload and those who are on hemodialysis⁴⁴ as well as in association with nilotinib use.¹⁰² Patients with chronic mucous membrane graft-vs-host disease may exhibit vitamin C deficiency.¹⁰³

Scurvy is a clinical diagnosis. Vitamin C levels normalize quickly with supplementation. Cutaneous biopsy will exhibit follicular hyperkeratosis, perifollicular hemorrhage, and fibrosis.⁹¹

Oral ascorbic acid supplementation should be initiated at 500 to 1000 mg daily in adults.¹⁰⁴ The cause of deficiency should be identified, and further supplementation should be decided based on patient risk factors. Lifestyle modifications, such as cessation of smoking and chronic alcohol use, is recommended. The diagnosis of scurvy should prompt workup for additional nutrient deficiencies.

Final Thoughts

Dermatologists play an important role in the early recognition of nutritional deficiencies, as cutaneous manifestations often are the first clue to diagnosis. Nutritional deficiencies are common yet underrecognized in the hospitalized patient and serve as an independent risk factor for patient morbidity and mortality.³ Awareness of the cutaneous manifestations of undernutrition as well as the risk factors for nutritional deficiency may expedite diagnosis and supplementation, thereby improving outcomes for hospitalized patients.

The World Health Organization defines malnutrition as deficiencies, excesses, or imbalances in an individual’s intake of energy and/or nutrients.¹ This review will focus on undernutrition, which may result from macronutrient or micronutrient deficiencies. Undernutrition in the hospitalized patient is a common yet underrecognized phenomenon, with an estimated prevalence of 20% to 50% worldwide.² Malnutrition is an independent risk factor for patient morbidity and mortality and has been associated with increased health care costs.³ Nutritional deficiencies may arise from inadequate nutrient intake, abnormal nutrient absorption, or improper nutrient utilization.⁴ Unfortunately, no standardized algorithm for screening and diagnosing patients with malnutrition exists, making early physical examination findings of utmost importance. Herein, we present a review of acquired nutritional deficiency dermatoses in the inpatient setting.

Protein-Energy Malnutrition

Protein-energy malnutrition (PEM) refers to a set of related disorders that include marasmus, kwashiorkor (KW), and marasmic KW. These conditions frequently are seen in developing countries but also have been reported in developed nations.⁵ Marasmus occurs from a chronic deficiency of protein and calories. Decreased insulin production and unopposed catabolism result in sarcopenia and loss of bone and subcutaneous fat.⁶ Affected patients include children who are less than 60% ideal body weight (IBW) without edema or hypoproteinemia.⁷ Kwashiorkor is the edematous form of PEM that develops from isolated protein deficiency, resulting in edema, diarrhea, and immunosuppression.⁶ Micronutrient deficiencies, oxidative stress, slow protein catabolism, and excess antidiuretic hormone have been proposed as potential drivers of KW.⁸ Kwashiorkor affects children between 60% and 80% IBW. Marasmic KW has features of both diseases, including children who are less than 60% IBW but with associated edema and/or hypoproteinemia.⁹

Although PEM is uncommon in adults, hospitalized patients carry many predisposing risk factors, including infections, malabsorptive conditions, psychiatric disease, and chronic illness (eTable). Patients with chronic infections present with findings consistent with marasmic KW due to lean body mass loss.

Zinc Deficiency

Zinc is an essential trace element that provides regulatory, structural, and catalytic functions across multiple biochemical pathways⁶ and serves as an enzymatic cofactor and key component for numerous transcription factors.¹⁷ Zinc is derived from food sources, and its concentration correlates with protein content.¹⁸ Zinc is found in both animal and plant-based proteins, albeit with a lower oral bioavailability in the latter. Zinc deficiency may be inherited or acquired. Primary acrodermatitis enteropathica is an autosomal-recessive disorder of the solute carrier family 39 member 4 gene, SLC39A4 (encodes zinc transporter ZIP4 on enterocytes); the result is abnormal zinc absorption from the small intestine.¹⁸

Acquired zinc deficiency occurs from decreased dietary zinc intake, impaired intestinal zinc absorption, excessive zinc elimination, or systemic states of high catabolism or low albumin (eTable). Total parenteral nutrition–associated deficiency has arisen when nutritional formulations did not contain trace elements during national shortages or when prolonged TPN was not anticipated and trace elements were removed.¹⁹ Zinc levels may already be low in patients with chronic illness or inflammation, so even a short period on TPN can precipitate deficiency.^18,19 Diets high in phytate may result in zinc deficiency, as phytate impairs intestinal zinc absorption.²⁰ Approximately 15% of patients with inflammatory bowel disease experienced zinc deficiency worldwide.²¹ In Crohn disease, zinc deficiency has been associated with active intestinal inflammation, increased risk for hospitalization, surgeries, and disease-related complications.^22,23

Medications such as antiepileptics, antimetabolites, or penicillamine may induce zinc deficiency, highlighting the importance of medication review for hospitalized patients (eTable). Catabolic states, frequently encountered in hospitalized patients, increase the risk for zinc deficiency.²⁴ Patients with necrolytic migratory erythema (associated with pancreatic glucagonomas) often experience low serum zinc levels.²⁵

The skin is the third most zinc-abundant tissue in the human body. Within keratinocytes, zinc is critical to normal proliferation and suppression of inflammation.¹⁷ Zinc also plays an important role in cutaneous immune function.²⁶ Zinc deficiency presents with sharply demarcated, flaccid pustules and bullae that erode into scaly, pink, eczematous or psoriasiform plaques. Lesions are found preferentially in acral and periorificial sites, often with crusting and exudate. The groin and flexural surfaces may be affected. Erosions often become secondarily impetiginized. Other cutaneous findings include angular cheilitis, stomatitis, glossitis, paronychia, onychodystrophy, generalized alopecia, and delayed wound healing.²⁶ Histopathology of skin lesions is characterized by granular layer loss, epidermal pallor, confluent parakeratosis, spongiosis, dyskeratosis, and psoriasiform hyperplasia.²⁷ Acquired bullous acrodermatitis enteropathica has been reported as a histologic mimicker of pemphigus foliaceous in patients on TPN.²⁸

Diagnosis of zinc deficiency is made by measuring plasma zinc levels. Fasting levels should be drawn in the morning, as they can fluctuate based on the time of day, stress levels, or inflammation.⁶ Sample hemolysis and anticoagulants high in zinc may falsely elevate plasma zinc. A normal zinc level is greater than 70 µg/dL; however, normal levels do not rule out deficiency.¹⁸ Measurement of zinc-dependent enzymes, such as alkaline phosphatase, can be a quick way to assess zinc status. Serum albumin also should be measured; because zinc is carried by albumin in the blood, hypoalbuminemia may result in secondary zinc deficiency.¹⁸

Zinc replacement therapy is largely through oral supplementation and should start at 0.5 to 2.0 mg/kg/d in adults with acquired disease.^29,30 Zinc sulfate is the most affordable and is the supplement of choice, with 50 mg of elemental zinc per 220 mg of zinc sulfate (~23% elemental zinc).³¹ Alternative zinc salts, such as zinc gluconate (13% elemental zinc), may be used. Patients with malabsorptive disorders often require parenteral supplementation.³² Clinical symptoms often will resolve within 1 to 2 weeks of supplementation.²⁹ In patients with primary acrodermatitis enteropathica, lifelong supplementation with 3 mg/kg/d elemental zinc should occur.⁶ Calcium and folate may reduce zinc absorption, while zinc supplementation can interfere with copper and iron absorption.³³

Iron Deficiency

Iron is an essential component of the hemoglobin molecule. Iron homeostasis and metabolism are tightly regulated processes that drive erythropoiesis. Only 5% to 10% of dietary iron is absorbed through nutrition, while the remainder is recycled from red cell breakdown. Both normal iron levels and iron deficiency (ID) are defined by age and gender.³⁴ Iron-deficiency anemia (IDA) is one of the most common cause-specific anemias worldwide.³⁵

Fatigue is the most common and earliest symptom of ID. In a single study, pallor was predictive of anemia in hospitalized patients; however, absence of pallor did not rule out anemia.³⁴ Dyspnea on exertion, tachycardia, dysphagia, and pica also may be reported. Cutaneous manifestations include koilonychia (Figure 2), glossitis, pruritus, angular cheilitis, and telogen effluvium. Plummer-Vinson syndrome is characterized by microcytic anemia, glossitis, and dysphagia.

Iron deficiency can be present despite a normal hemoglobin level. Serum ferritin and percentage transferrin saturation are key to early identification of IDA.³⁵ Ferritin levels lower than 30 µg/L confirm the diagnosis. Decreased transferrin saturation and increased total iron binding capacity aid in the diagnosis of IDA. Serum ferritin is an acute-phase reactant, and levels may be falsely elevated in the setting of inflammation or infection.

Essential Fatty Acid Deficiency

Essential fatty acids (EFAs) including linoleic and α-linolenic acid cannot be synthesized by the human body and must be obtained through diet (mostly plant oils). Essential fatty acids have various functions, including maintaining phospholipid membrane integrity, forming prostaglandins and leukotrienes, and storing energy.⁴⁰ Essential fatty acids are important in the structure and function of the stratum corneum and are crucial in maintaining epidermal barrier function.⁴¹ Increased epidermal permeability and transepidermal water loss may be the first signs of EFA deficiency (EFAD).⁴²

The cutaneous manifestations of EFAD include xerosis, weeping eczematous plaques, and erosions in intertriginous sites. The lesions may progress to widespread desquamation and erythema. With time, the skin can become thick and leathery. Alopecia may occur, and hair may depigment.⁷ Additional findings include poor wound healing and increased susceptibility to infections.^43,44

Essential fatty acid deficiency may occur when dietary fat intake is severely restricted or in malabsorptive states.^45,46 It develops in patients on prolonged TPN, typically when receiving fat-restricted nutrition,^47,48 as occurs in hypertriglyceridemia.⁴⁷ Essential fatty acid deficiency has developed in patients on TPN containing EFAs,⁴⁷ as the introduction of novel intravenous lipid emulsions has resulted in varying proportions of EFA.⁴⁰ Premature neonates are particularly at risk for EFAD.⁴⁹

The diagnosis of EFAD involves the measurement of the triene to tetraene ratio. A ratio of more than 0.2 suggests EFAD, but the clinical signs are not seen until the ratio is over 0.4.⁴⁰ Low plasma levels of linoleic, linolenic, and arachidonic acids also are seen. Elevated liver function tests are supportive of the diagnosis. Biochemical findings typically are seen before cutaneous manifestations.⁴⁰

Treatment of EFAD includes topical, oral, or intravenous replacement of EFAs. Improvement of EFAD with the application of topical linoleic acid to the skin has been reported.⁵⁰ Patients receiving TPN should undergo assessment of parenteral lipid emulsion to ensure adequate fatty acid composition.

Vitamin A Deficiency

Vitamin A (retinol) is a fat-soluble vitamin that plays a critical role in keratinization, epithelial proliferation, and cellular differentiation.⁶ Vitamin A is found in animal products as retinyl esters and in plants as beta-carotene. Vitamin A has 2 clinically important forms: all-trans retinoic acid and 11-cis-retinal. All-trans retinoic acid is involved in cellular differentiation and regulating gene transcription, while 11-cis-retinal is key to rhodopsin generation required for vision. Vitamin A deficiency presents with early ophthalmologic findings, specifically nyctalopia, or delayed adaptation to the dark.⁵¹ Xerophthalmia, abnormal conjunctival keratinization, and Bitot spots subsequently develop and may progress to corneal ulceration and blindness.⁶

Vitamin A deficiency manifests in the skin as follicular hyperkeratosis, or phrynoderma. Notably, numerous other micronutrient deficiencies may result in phrynoderma. Clinically, multiple pigmented keratotic papules of various sizes, many with a central keratinous plug, are distributed symmetrically on the extensor elbows, knees, shoulders, buttocks, and extremities. The skin surrounding these lesions may be scaly and hyperpigmented.⁵² Generalized xerosis without preceding nyctalopia has been reported.⁵³ Accompanying pityriasis alba may develop.⁵² Lesions on the face may mimic acne, while lesions on the extremities may simulate a perforating disorder. Histopathology of phrynoderma reveals epidermal hyperkeratosis, follicular hyperkeratosis, and follicular plugging.⁵²

Vitamin A deficiency can be diagnosed by measuring serum retinol levels, with levels lower than 20 µg/dL being diagnostic of deficiency.⁵⁶ Decreased serum retinol in patients hospitalized with flaring irritable bowel disorder has been repeatedly reported.^57-59 Notably, serum retinol concentration does not decline until liver reserves of vitamin A are nearing exhaustion.³³

The US Food and Drug Administration requires manufacturers to list retinol activity equivalents on labels. One international unit of retinol is equivalent to 0.3 µg of retinol activity equivalents.⁶⁰ The treatment of vitamin A deficiency involves high-dose oral supplementation when possible.⁶¹ Although dependent on age, the treatment dose for most adults with vitamin A deficiency is 3000 µg (10,000 IU) once daily.

Phrynoderma has been specifically treated with salicylic acid ointment 3% and intramuscular vitamin A.⁶² Topical urea cream also may treat phrynoderma.⁶³

Vitamin B₂

Vitamin B₂ (riboflavin) is absorbed in the small intestine and converted into 2 biologically active forms—flavin adenine dinucleotide and flavin mononucleotide—which serve as cofactors in metabolic and oxidation-reduction reactions. Malabsorptive disorders and bowel resection can lead to riboflavin deficiency.⁶⁴ Other at-risk populations include those with restrictive diets,⁶⁵ psychiatric illness, or systemic illness (eTable). Riboflavin can be degraded by light (deficiency has been reported after phototherapy for neonatal jaundice⁶⁶) and following boric acid ingestion.⁶⁷ Medications, including long-term treatment with antiepileptics, may lead to riboflavin deficiency.⁶⁸

Riboflavin is critical to maintaining collagen production. Riboflavin deficiency may manifest clinically with extensive seborrheiclike dermatitis,⁴⁴ intertrigolike dermatitis,⁶⁹ or oral-ocular-genital syndrome.⁷⁰ Angular cheilitis may accompany an atrophic tongue that is deep red in color. The scrotum is characteristically involved in men, with confluent dermatitis extending onto the thighs and sparing the midline. Red papules and painful fissures may develop. Balanitis and phimosis have been reported. Testing for riboflavin deficiency should be considered in patients with refractory seborrheic dermatitis.

Riboflavin stores are assessed by the erythrocyte glutathione reductase activity coefficient.⁴⁴ A level of 1.4 or higher is consistent with deficiency. Serum riboflavin levels, performed after a 12-hour fast, may support the diagnosis but are less sensitive. Patients with glucose-6-phosphate deficiency cannot be assessed via the erythrocyte glutathione reductase activity coefficient and may instead require evaluation of 24-hour urine riboflavin level.⁴⁴

Vitamin B₃

Vitamin B₃ (niacin, nicotinamide, nicotinic acid) is found in plant and animal products or can be derived from its amino acid precursor tryptophan. Niacin deficiency results in pellagra, characterized by dermatitis, dementia, and diarrhea.⁷¹ The most prominent feature is a symmetrically distributed photosensitive dermatitis of the face, neck (called Casal necklace)(Figure 3), chest, dorsal hands, and extensor arms. The eruption may begin with erythema, vesicles, or bullae (wet pellagra) and evolve into thick, hyperpigmented, scaling plaques.⁷¹ The skin may take on a copper tone and become atrophic.⁷² Dull erythema with overlying yellow powdery scale (called sulfur flakes) at follicular orifices has been described on the nasal bridge.⁷³

Causes of niacin deficiency include malabsorptive conditions, malignancy (including carcinoid tumors), parenteral nutrition, psychiatric disease,^74,75 and restrictive diets (eTable).⁷⁶ Carcinoid tumors divert tryptophan to serotonin resulting in niacin deficiency.⁷⁷

The diagnosis of niacin deficiency is based on clinical findings and response to supplementation.⁷⁵ Low niacin urinary metabolites (N-methylnicotinamide and 2-pyridone) may aid in diagnosis.⁶ Treatment generally includes oral nicotinamide 100 mg every 6 hours; the dose can then be tapered to 50 mg every 8 to 12 hours until symptoms resolve. Severe deficiency may require parenteral nicotinamide 1 g 3 to 4 times daily.⁷⁵

Vitamin B₆

Vitamin B₆ (pyridoxine, pyridoxamine, pyridoxal) is found in whole grains and plant and animal products. Vitamin B₆ functions as a coenzyme in many metabolic pathways and is involved in the conversion of tryptophan to niacin.⁴⁴ Absorption requires hydrolysis by intestinal phosphates and transport to the liver for rephosphorylation prior to release in active form.⁶

Cutaneous findings associated with vitamin B₆ deficiency include periorificial and perineal seborrheic dermatitis,⁷⁸ angular stomatitis, and cheilitis, with associated burning, redness, and tongue edema.⁶ Vitamin B₆ deficiency is a rarely reported cause of burning mouth syndrome.⁷⁹ Because vitamin B₆ is involved in the conversion of tryptophan to niacin, deficiency also may present with pellagralike findings.⁷⁰ Other clinical symptoms are outlined in the eTable.^80,81

Conditions that increase risk for vitamin B₆ deficiency are highlighted in the eTable and include malabsorptive disorders; psychiatric illness⁸²; and chronic disease, especially end-stage renal disease.⁸³ Vitamin B₆ deficiency associated with chronic alcohol use is due to both inadequate vitamin B₆ intake as well as reduced hepatic storage.⁷⁸ Medications such as isoniazid, hydralazine, and oral contraceptives may decrease vitamin B₆ levels (eTable).⁸²

Vitamin B₆ can be measured in the plasma as pyridoxal 5′-phosphate. Plasma concentrations of less than 20 nmol/L are suggestive of deficiency.⁸² Indirect tests include tryptophan and methionine loading.⁶ The treatment of vitamin B₆ deficiency is determined by symptom severity. Recommendations for oral supplementation range from 25 to 600 mg daily.⁸² Symptoms typically improve on 100 mg daily.⁶

Vitamins B₉ and B₁₂

Deficiencies of vitamins B₉ (folic acid, folate) and B₁₂ (cobalamin) have similar clinical presentations. Folate is essential in the metabolism of amino acids, purines, and pyrimidines.⁶ Cobalamin, found in animal products, is a cofactor for methionine synthase and methylmalonyl-CoA mutase.⁸⁴ Megaloblastic anemia is the main finding in folate or cobalamin deficiency. Neurologic findings only accompany cobalamin deficiency. Risk factors for folate deficiency include malabsorptive conditions,⁶ chronic alcohol use,⁸⁵ and antifolate medication use (eTable).⁶

Cobalamin absorption requires gastric acid and intrinsic factor binding in the duodenum. Deficiency may occur from strict diets, psychiatric illness, old age,⁸⁶ decreased gastric acid secretion,⁸⁷ abnormal intrinsic factor function, or intestinal infections.⁶

Generalized cutaneous hyperpigmentation may be the first manifestation of vitamins B₉ and B₁₂ deficiency.⁸⁸ Typically accentuated in acral creases and the oral cavity, pigmentation may mimic Addison disease. Hair depigmentation and linear streaking of the nails are reported.⁸⁴ The tongue becomes painful and red with atrophy of the filiform papillae (Hunter glossitis).⁷⁸ Linear lesions on the tongue and hard palate may serve as an early sign of cobalamin deficiency.⁸⁹

Folate deficiency is diagnosed by measuring the plasma folate level; coincidental cobalamin deficiency should be excluded. Deficiency is managed with oral supplementation (when possible) with 1 to 5 mg of folate daily.⁶ Cobalamin deficiency is based on low serum levels (<150 pg/mL is diagnostic).⁸⁶ Cobalamin deficiency may take years to develop, as vitamin B₁₂ exists in large body stores.⁶ Serum methylmalonic acid may be elevated in patients with clinical features but normal-low serum vitamin B₁₂ level.⁸⁶ Treatment of vitamin B₁₂ deficiency is with oral (2 mg once daily) or parenteral (1 mg every 4 weeks then maintained at once monthly) cyanocobalamin. For patients with neurologic symptoms, intramuscular injection should be given.⁸⁶ The underlying cause of deficiency must be elucidated and treated.

Vitamin C Deficiency

Vitamin C (ascorbic acid) is an essential cofactor for the hydroxylation of proline and lysine residues in collagen synthesis. Plant-based foods are the main dietary source of vitamin C, and deficiency presents clinically as scurvy. Cutaneous findings include follicular hyperkeratosis, perifollicular petechiae, and curled hair shafts (corkscrew hairs)(Figure 4). Ecchymoses of the lower extremities, forearms, and abdomen may be seen. Nodules representing intramuscular and subcutaneous hemorrhage can be present.⁹⁰ Woody edema may mimic cellulitis, while lower extremity hemorrhage may mimic vasculitis. Gingival hyperplasia, hemorrhage, and edema may occur,⁹⁰ along with linear splinter hemorrhages.⁹¹

Hypovitaminosis C has been routinely demonstrated in hospitalized patients.⁹² Scurvy may occur in patients on strict diets,⁹³ chronic alcohol use,⁹⁴ psychiatric illness,⁹⁵ or gastrointestinal tract disease (eTable).^96-99 Those with low socioeconomic status⁷⁰ or dementia¹⁰⁰ as well as the elderly also are at risk.¹⁰¹ Scurvy has developed in patients with iron overload and those who are on hemodialysis⁴⁴ as well as in association with nilotinib use.¹⁰² Patients with chronic mucous membrane graft-vs-host disease may exhibit vitamin C deficiency.¹⁰³

Scurvy is a clinical diagnosis. Vitamin C levels normalize quickly with supplementation. Cutaneous biopsy will exhibit follicular hyperkeratosis, perifollicular hemorrhage, and fibrosis.⁹¹

Oral ascorbic acid supplementation should be initiated at 500 to 1000 mg daily in adults.¹⁰⁴ The cause of deficiency should be identified, and further supplementation should be decided based on patient risk factors. Lifestyle modifications, such as cessation of smoking and chronic alcohol use, is recommended. The diagnosis of scurvy should prompt workup for additional nutrient deficiencies.

Final Thoughts

Dermatologists play an important role in the early recognition of nutritional deficiencies, as cutaneous manifestations often are the first clue to diagnosis. Nutritional deficiencies are common yet underrecognized in the hospitalized patient and serve as an independent risk factor for patient morbidity and mortality.³ Awareness of the cutaneous manifestations of undernutrition as well as the risk factors for nutritional deficiency may expedite diagnosis and supplementation, thereby improving outcomes for hospitalized patients.

Compounding is a way of mixing or combining medications in formulations that are not widely available. Because dermatology is a field that includes a variety of topical treatments, compounding topicals is a way to create unique and customized treatment options for patients.

Advantages

Custom compounding topical medications has many benefits in comparison to traditional topical formulations. Compounding is a way of personalizing prescriptions to best suit the individual needs of each patient. Multiple ingredients with different mechanisms of action can be combined in a single medication for patients to use, which ultimately can simplify their treatment regimen.¹ For rare conditions with uncommon treatments, compounding pharmacies can provide medications that are not widely available in retail pharmacies. Compounding topical medications also can be an efficient way of prescribing medications without dealing with the uncertainty of prior authorizations or how much the co-pay will be.

Disadvantages

One of the major disadvantages of compounding topical medications is the lack of safety data. Although most active drugs have been tested independently, there is little data on the safety of compounding 2 or more active drugs. Furthermore, the vehicle used may change the permeability of the topical formulation, and systemic absorption may be possible. Two deaths were reported with the application of compounded topical lidocaine and tetracaine gel due to systemic absorption. In these cases, the gel was used before laser hair removal, and it was applied under occlusion to greater than 50% of the body surface area, leading to fatal systemic absorption.^1,2

One of the hypothetical benefits of compounding topicals is being able to avoid side effects of systemic medications. However, depending on the skin intactness and the strength of the medication used, systemic adverse effects have been reported.¹ In a case series of 2 patients detailing the use of amitriptyline cream 5% and 10% for neuropathic pain, the patient using 10% cream experienced systemic effects of drowsiness and discontinued treatment.³

Another major disadvantage of compounding topicals is a lack of published data about the efficacy, especially given the unique nature of what is being compounded. When combining multiple medications, there are little to no published data about the efficacy of these formulations and how they compare to monotherapy. Although there may be data about the efficacy of an oral agent, it does not translate to the topical form being safe and efficacious. Much of the published data of topical formulations is limited to case reports and case series.

Finally, many compounded medications are not covered by insurance, and the out-of-pocket cost may be prohibitive for some patients. Compounding pharmacies typically will give patients a price estimate before the prescription is filled. When compounding topicals for patient use, it is important to counsel patients about the following:the unknown safety profile; lack of data regarding efficacy; and cost, as the medication likely will not be covered by insurance.

Pharmaceutical Regulations

After a contaminated product at a compounding pharmacy in New England led to an outbreak of fungal meningitis, there has been increased regulation by the US Food and Drug Administration.⁴ To meet safety regulations, compounding pharmacies must adhere to the standards set by the US Pharmacopeia. The US Food and Drug Administration says that physicians are not to prescribe compounded medications that are “unapproved, adulterated, or misbranded drugs,” which has been interpreted to mean that compounded medications should not mimic a branded medication but should instead be a unique formulation or strength.^4,5 Thus, while compounding topicals may provide an alternative when a specific medication is not covered by insurance, it cannot be the same as a branded medication.

Pharmaceutical Options

Most major cities have custom compounding pharmacies or apothecaries. One of the benefits of using a local compounding pharmacy is that you typically can speak directly with the pharmacist about your patient’s diagnosis and his/her specific needs. The pharmacist can guide you through which formulations to compound, which strength to choose, and the best vehicle to use as a base. This expertise is invaluable in the compounding process. There also are online compounding pharmacies available.

Options for Bases

Dermatologists can request for their medications to be compounded in traditional over-the-counter emollients or petrolatum-based products, which work by passively diffusing through the stratum corneum into the superficial epidermis to treat skin conditions.¹ For a topical drug to be absorbed effectively through the skin and into the general circulation, the vehicle needs to have affinity for both lipid and aqueous environments. Lipophilic drugs will absorb better through the stratum corneum, while hydrophilic drugs will absorb better through the aqueous layer of the epidermis. For a topical formulation to be both hydrophobic and hydrophilic, components such as viscosity enhancers and permeation enhancers can be added.¹ Many compounding pharmacies also have proprietary bases that can be used.

Final Thoughts

Compounding topical medications in dermatology provides dermatologists with the ability to provide unique formulations to best suit their patients’ individual needs. However, dermatologists must keep in mind the limitations of compounding topicals, including a lack of data on efficacy and safety.
