The Centers for Disease Control and Prevention is alerting clinicians to be on the lookout for a severe antifungal-resistant form of tinea, as it was recently detected in two patients in New York.

Tinea, or ringworm, one of the most common fungal infections, is responsible for almost 5 million outpatient visits and 690 hospitalizations annually, according to the CDC.

Over the past 10 years, severe, antifungal-resistant tinea has spread in South Asia, in part because of the rise of a new dermatophyte species known as Trichophyton indotineae, wrote the authors of a report on the two patients with the drug-resistant strain. This epidemic “has likely been driven by misuse and overuse of topical antifungals and corticosteroids,” added the authors, in Morbidity and Mortality Weekly Report.

The cases were detected by a New York City dermatologist. In the first case, a 28-year-old woman developed a widespread pruritic eruption in the summer of 2021. She did not consult a dermatologist until December, when she was in the third trimester of pregnancy. She had large, annular, scaly, pruritic plaques on her neck, abdomen, pubic region, and buttocks, but had no underlying medical conditions, no known exposures to someone with a similar rash, and no recent international travel history.

After she gave birth in January, she started oral terbinafine therapy but had no improvement after 2 weeks. Clinicians administered a 4-week course of itraconazole, which resolved the infection.

The second patient, a 47-year-old woman with no medical conditions, developed a rash while in Bangladesh in the summer of 2022. Other family members had a similar rash. She was treated with topical antifungal and steroid combination creams but had no resolution. Back in the United States, she was prescribed hydrocortisone 2.5% ointment and diphenhydramine, clotrimazole cream, and terbinafine cream in three successive emergency department visits. In December 2022, dermatologists, observing widespread, discrete, scaly, annular, pruritic plaques on the thighs and buttocks, prescribed a 4-week course of oral terbinafine. When the rash did not resolve, she was given 4 weeks of griseofulvin. The rash persisted, although there was 80% improvement. Clinicians are now considering itraconazole. The woman’s son and husband are also being evaluated, as they have similar rashes.

In both cases, skin culture isolates were initially identified as Trichophyton mentagrophytes. Further analysis at the New York State Department of Health’s lab, using Sanger sequencing of the internal transcribed spacer region of the ribosomal gene, followed by phylogenetic analysis, identified the isolates as T. indotineae.

The authors note that culture-based techniques used by most clinical laboratories typically misidentify T. indotineae as T. mentagrophytes or T. interdigitale. Genomic sequencing must be used to properly identify T. indotineae, they wrote.

Clinicians should consider T. indotineae in patients with widespread ringworm, especially if they do not improve with topical antifungals or oral terbinafine, said the authors. If T. indotineae is suspected, state or local public health departments can direct clinicians to testing.

The authors report no relevant financial relationships.

In this patient, bacterial and viral cultures were taken and varicella zoster virus (VZV) was isolated. Additionally, Orthopox DNA by PCR and Monkeypox (mpox) virus DNA by PCR were detected. Herpes simplex virus and bacterial viral cultures were negative. Valacyclovir was started at the time of presentation and the patient’s lesions resolved without sequelae.

Mpox is a zoonotic double-stranded DNA virus that is part of the Orthopoxvirus family, including the West African and Central African variants. This disease presents similarly to smallpox, so most mpox research was conducted around the time smallpox was eradicated. It was not until 1970, when the disease was isolated from a patient with suspected smallpox in the Democratic Republic of the Congo (DRC), that human mpox was considered a distinct disease. An epidemic outbreak in the United States occurred in 2003 related to infected prairie dogs, and travel-related outbreaks have been more recently reported up until May 2022, in which mpox was reported in nonendemic areas including North America, Europe, and Australia. Most cases in this outbreak occurred in men who have sex with men (MSM), but this is not always the case, and mpox is not necessarily considered a sexually transmitted infection. Mpox presents similarly to smallpox and VZV, so using laboratory tests is important in diagnosing and tracking this disease.

Although it is not easily transmitted, the disease can spread through bodily secretions both directly and indirectly. Mpox typically begins with a prodrome that includes fever, headache, myalgia, and fatigue. This is followed by lymphadenopathy that precedes and coincides with rash development. The lymph nodes are firm, tender, may be painful, and are a defining factor in presentation that differs from smallpox and varicella. The rash typically starts on the face, then presents on the body in a centrifugal distribution. However, cases related to sexual transmission present with anogenital lesions. The lesions are characterized by a progression from maculopapular to vesiculopustular, and can vary widely in quantity.

Notably, individuals are contagious from the onset of the prodrome until the lesions have scabbed over and fallen off. The eruptive nature of the later lesions poses a threat of secondary infection, and is often accompanied by a second febrile period that signifies deterioration of the patient’s condition. Other signs of secondary infection are variable and include pulmonary symptoms, vomiting, diarrhea, ocular infections, and in rare cases, encephalitis. These sequelae are more common in unvaccinated and immunocompromised individuals. Long-term complications of mpox include pitted scarring from cutaneous lesions with children being more susceptible to severe disease. The mortality rate for the disease is very low. (As of May 10, 2023, there have been 30,395 mpox cases reported in the United States, and 42 deaths, according to the Centers for Disease Control and Prevention.)

There are a variety of diagnostic tests that can aid in mpox identification, but they are most strongly supported when combined with clinical and epidemiological data. The best, least invasive method includes collection of lesion exudate or crust on a swab, and viral DNA is best preserved by keeping the specimen in a cool, dry, and dark environment. PCR is considered the standard, and electron microscopy and immunohistochemistry are valid tests, but all modalities require sophisticated technicians with the proper laboratory equipment. This is limiting because many cases present in underserved areas that lack the facilities for proper, real-time analysis. Antigen and antibody-based tests can be used, but cross-reactivity of other orthopoxviridae limits confirmation of mpox infection. Vaccination status, history and location must be considered.

Vaccination is the chief form of prevention for mpox, although it is not considered entirely protective. Smallpox vaccination provides protection, but widespread administration of the vaccine is no longer practiced, and an estimated 70% of the global population is no longer vaccinated. Vaccination is recommended for anyone at risk of exposure, but as this is a live, attenuated vaccine, the immune status of the patient is important to keep in mind. Tecovirimat and other antiviral medications including cidofovir and brincidofovir may be considered in severe cases.

This case is unique as our patient, who had no known risk factors for mpox, presented with mpox and VZV, simultaneously. Although clinical presentation and epidemiological patterns between these diseases differ, there have been a limited number of cases of coinfection reported in the literature, mainly in the DRC where mpox is endemic. Diagnosis must be made by separate laboratory tests and there are differences in presentation between independent and coinfection for these viruses. Notably, patients with mpox/VZV coinfection may be less likely to present with lesions on the face, thorax, arms, palms, and soles than those with only mpox but experience a higher lesion burden than those afflicted by only VZV. Coinfection may be related to reactivation of dormant VZV, or increased susceptibility to secondary infection when infected with one virus.

Overweight boy, infertile man?

When it comes to causes of infertility, history and science have generally focused on women. A lot of the research overlooks men, but some previous studies have suggested that male infertility contributes to about half of the cases of couple infertility. The reason for much of that male infertility, however, has been a mystery. Until now.

A group of Italian investigators looked at the declining trend in sperm counts over the past 40 years and the increase of childhood obesity. Is there a correlation? The researchers think so. Childhood obesity can be linked to multiple causes, but the researchers zeroed in on the effect that obesity has on metabolic rates and, therefore, testicular growth.

Collecting data on testicular volume, body mass index (BMI), and insulin resistance from 268 boys aged 2-18 years, the researchers discovered that those with normal weight and normal insulin levels had testicular volumes 1.5 times higher than their overweight counterparts and 1.5-2 times higher than those with hyperinsulinemia, building a case for obesity being a factor for infertility later in life.

Since low testicular volume is associated with lower sperm count and production as an adult, putting two and two together makes a compelling argument for childhood obesity being a major male infertility culprit. It also creates even more urgency for the health care industry and community decision makers to focus on childhood obesity.

It sure would be nice to be able to take one of the many risk factors for future human survival off the table. Maybe by taking something, like cake, off the table.

Fecal transplantation moves to the kitchen

Fecal microbiota transplantation is an effective way to treat Clostridioides difficile infection, but, in the end, it’s still a transplantation procedure involving a nasogastric or colorectal tube or rather large oral capsules with a demanding (30-40 capsules over 2 days) dosage. Please, Science, tell us there’s a better way.

Science, in the form of investigators at the University of Geneva and Lausanne University Hospital in Switzerland, has spoken, and there may be a better way. Presenting fecal beads: All the bacterial goodness of donor stool without the tubal insertions or massive quantities of giant capsules.

We know you’re scoffing out there, but it’s true. All you need is a little alginate, which is a “biocompatible polysaccharide isolated from brown algae” of the Phaeophyceae family. The donor feces is microencapsulated by mixing it with the alginate, dropping that mixture into water containing calcium chloride, turning it into a gel, and then freeze-drying the gel into small (just 2 mm), solid beads.

Sounds plausible enough, but what do you do with them? “These brownish beads can be easily dispersed in a liquid or food that is pleasant to eat. They also have no taste,” senior author Eric Allémann, PhD, said in a statement released by the University of Geneva.

Pleasant to eat? No taste? So which is it? If you really want to know, watch fecal beads week on the new season of “The Great British Baking Show,” when Paul and Prue judge poop baked into crumpets, crepes, and crostatas. Yum.
 

We’re on the low-oxygen diet

Nine out of ten doctors agree: Oxygen is more important to your continued well-being than food. After all, a human can go weeks without food, but just minutes without oxygen. However, ten out of ten doctors agree that the United States has an obesity problem. They all also agree that previous research has shown soldiers who train at high altitudes lose more weight than those training at lower altitudes.

PBRC

So, on the one hand, we have a country full of overweight people, and on the other, we have low oxygen levels causing weight loss. The solution, then, is obvious: Stop breathing.

More specifically (and somewhat less facetiously), researchers from Louisiana have launched the Low Oxygen and Weight Status trial and are currently recruiting individuals with BMIs of 30-40 to, uh, suffocate themselves. No, no, it’s okay, it’s just when they’re sleeping.

Fine, straight face. Participants in the LOWS trial will undergo an 8-week period when they will consume a controlled weight-loss diet and spend their nights in a hypoxic sealed tent, where they will sleep in an environment with an oxygen level equivalent to 8,500 feet above sea level (roughly equivalent to Aspen, Colo.). They will be compared with people on the same diet who sleep in a normal, sea-level oxygen environment.

The study’s goal is to determine whether or not spending time in a low-oxygen environment will suppress appetite, increase energy expenditure, and improve weight loss and insulin sensitivity. Excessive weight loss in high-altitude environments isn’t a good thing for soldiers – they kind of need their muscles and body weight to do the whole soldiering thing – but it could be great for people struggling to lose those last few pounds. And it also may prove LOTME’s previous thesis: Air is not good.

So, on the one hand, we have a country full of overweight people, and on the other, we have low oxygen levels causing weight loss. The solution, then, is obvious: Stop breathing.

More specifically (and somewhat less facetiously), researchers from Louisiana have launched the Low Oxygen and Weight Status trial and are currently recruiting individuals with BMIs of 30-40 to, uh, suffocate themselves. No, no, it’s okay, it’s just when they’re sleeping.

Fine, straight face. Participants in the LOWS trial will undergo an 8-week period when they will consume a controlled weight-loss diet and spend their nights in a hypoxic sealed tent, where they will sleep in an environment with an oxygen level equivalent to 8,500 feet above sea level (roughly equivalent to Aspen, Colo.). They will be compared with people on the same diet who sleep in a normal, sea-level oxygen environment.

The study’s goal is to determine whether or not spending time in a low-oxygen environment will suppress appetite, increase energy expenditure, and improve weight loss and insulin sensitivity. Excessive weight loss in high-altitude environments isn’t a good thing for soldiers – they kind of need their muscles and body weight to do the whole soldiering thing – but it could be great for people struggling to lose those last few pounds. And it also may prove LOTME’s previous thesis: Air is not good.

Overweight boy, infertile man?

When it comes to causes of infertility, history and science have generally focused on women. A lot of the research overlooks men, but some previous studies have suggested that male infertility contributes to about half of the cases of couple infertility. The reason for much of that male infertility, however, has been a mystery. Until now.

A group of Italian investigators looked at the declining trend in sperm counts over the past 40 years and the increase of childhood obesity. Is there a correlation? The researchers think so. Childhood obesity can be linked to multiple causes, but the researchers zeroed in on the effect that obesity has on metabolic rates and, therefore, testicular growth.

Collecting data on testicular volume, body mass index (BMI), and insulin resistance from 268 boys aged 2-18 years, the researchers discovered that those with normal weight and normal insulin levels had testicular volumes 1.5 times higher than their overweight counterparts and 1.5-2 times higher than those with hyperinsulinemia, building a case for obesity being a factor for infertility later in life.

Since low testicular volume is associated with lower sperm count and production as an adult, putting two and two together makes a compelling argument for childhood obesity being a major male infertility culprit. It also creates even more urgency for the health care industry and community decision makers to focus on childhood obesity.

It sure would be nice to be able to take one of the many risk factors for future human survival off the table. Maybe by taking something, like cake, off the table.

Fecal transplantation moves to the kitchen

Fecal microbiota transplantation is an effective way to treat Clostridioides difficile infection, but, in the end, it’s still a transplantation procedure involving a nasogastric or colorectal tube or rather large oral capsules with a demanding (30-40 capsules over 2 days) dosage. Please, Science, tell us there’s a better way.

Science, in the form of investigators at the University of Geneva and Lausanne University Hospital in Switzerland, has spoken, and there may be a better way. Presenting fecal beads: All the bacterial goodness of donor stool without the tubal insertions or massive quantities of giant capsules.

We know you’re scoffing out there, but it’s true. All you need is a little alginate, which is a “biocompatible polysaccharide isolated from brown algae” of the Phaeophyceae family. The donor feces is microencapsulated by mixing it with the alginate, dropping that mixture into water containing calcium chloride, turning it into a gel, and then freeze-drying the gel into small (just 2 mm), solid beads.

Sounds plausible enough, but what do you do with them? “These brownish beads can be easily dispersed in a liquid or food that is pleasant to eat. They also have no taste,” senior author Eric Allémann, PhD, said in a statement released by the University of Geneva.

Pleasant to eat? No taste? So which is it? If you really want to know, watch fecal beads week on the new season of “The Great British Baking Show,” when Paul and Prue judge poop baked into crumpets, crepes, and crostatas. Yum.
 

We’re on the low-oxygen diet

Nine out of ten doctors agree: Oxygen is more important to your continued well-being than food. After all, a human can go weeks without food, but just minutes without oxygen. However, ten out of ten doctors agree that the United States has an obesity problem. They all also agree that previous research has shown soldiers who train at high altitudes lose more weight than those training at lower altitudes.

Infectious diseases are the most common reason for rehospitalization among patients with spinal cord injuries (SCI), regardless of the number of years postinjury.¹ The appropriate use and selection of antibiotics for properly diagnosed infectious diseases is especially important for this population. This principle helps to avoid the development of drug-resistant organisms and reduces the risk of recurrent infections, aligning with antibiotic stewardship.

Antibiotics are the most common class of drug allergies in the general population, and penicillin is the most frequently reported allergen (up to 10%).² Prescription drug–induced anaphylaxis is severe and life threatening with a reported frequency of 1.1%. Penicillin and sulfonamide (46 and 15 per 10,000 patients, respectively) are the most common allergens.³ Although there is a significant difference between an adverse drug reaction (ADR) and true hypersensitivity, once documented in the electronic health record (EHR) as an allergy, this information deters use of the listed drugs.

Genitourinary, skin, and respiratory diseases are the leading causes for rehospitalization in patients with SCI.¹ A large proportion of these are infectious in etiology and require antibiotic treatment. In fact, persons with SCI are at high risk for antibiotic overuse and hospital-acquired infection due to chronic bacteriuria, frequent health care exposure, implanted medical devices, and other factors.⁴ Concurrently, there is a crisis of antibiotic-resistant bacteria proliferation, described asa threat to patient safety and public health.^5,6 Its severity is illustrated by the report that 38% of the cultures from patients with spinal cord injury are multidrug resistant gram-negative organisms.⁷

The SCI center at James A. Haley Veterans’ Hospital (JAHVH) in Tampa, Florida, serves a high concentration of active-duty military members and veterans with SCI. A study that reviews the exact frequency of antibiotic drug allergies listed on the EHR would be a key first step to identify the magnitude of this issue. The results could guide investigation into differentiating true allergies from ADRs, thereby widening the options for potentially life-saving antibiotic treatment.

Methods

We performed a retrospective chart review of patients included in the local SCI registry between October 1, 2015, and September 30, 2017. We collected data on patient demographics (age, sex, race and ethnicity) and a description of patients’ injuries (International Standards for Neurological Classification of Spinal Cord Injury [ISNCSCI] and etiology of injury [traumatic vs atraumatic]). The outcomes included antibiotic allergy and ADRs.

In the EHR, allergies can be listed toward an antibiotic class or a specific antibiotic. An allergy to each specific antibiotic would be recorded separately; however, overlap among antibiotic classes was not duplicated. For example, if a subject has a listed antibiotic allergy to ceftriaxone and cefepime with listed reactions, we would record allergies to each of these antibiotics but would only report a single allergy to the cephalosporin subclass.

Since we did not differentiate hypersensitivity reactions (HSRs) from other ADRs, the reported reactions were grouped by signs and symptoms. There is a variety of terms used to report similar reactions, and best efforts were made to record the data as accurately as possible. Patient-reported history for risk stratification is a tool we used to group these historical reactions into high- vs low-risk for severe reactions. High-risk signs are those listed as anaphylaxis; anaphylactic reactions; angioedema presenting as swelling of mouth, eyes, lips, or tongue; blisters or ulcers involving the lips, mouth, eyes, urethra, vagina, or peeling skin; respiratory changes; shortness of breath; dyspnea; hypotension; or organ involvement (kidneys, lungs, liver).⁶

Inclusion criteria were all veterans who were diagnosed with tetraplegia or paraplegia and received annual evaluation between October 1, 2015, and September 30, 2017. We chose this period because it was the beginning of a financial year at the JAHVH SCI department using the SCI registry. The SCI annual evaluation is a routine practitioner encounter with the veteran, along with appropriate laboratory testing and imaging to follow up potential chronic health issues specific to patients with SCI. Annual evaluations provide an opportunity to maintain routine health screening and preventive care. Patients who had significant portions of data missing or missing elements of primary outcomes were excluded from analysis. The study was reviewed and approved by the University of South Florida Institutional Review Board (VA IRBNet #1573370-4 on September 9, 2019).

Results

Of 1866 patients reviewed, 207 (11.1%) were excluded due to missing data, resulting in 1659 records that were analyzed. Mean age was 64 years, and male to female ratio was about 10 to 1. Most of the SCI or diseases were classified as incomplete (n = 1249) per ISNCSCI (absence of sensory and motor function in the lowest sacral segments) compared with 373 classified as complete.

Of the 1659 patients, 494 (29.8%) had a recorded allergy to antibiotics. The most frequently recorded were 217 penicillin (13.1%), 159 sulfa drugs (9.6%), 75 fluoroquinolone (4.5%), 66 cephalosporin (4.0%), and 44 vancomycin (2.7%) allergies.

Discussion

In this study, we evaluated the frequency and characteristics of antibiotic allergies at a single SCI center to better identify potential areas for quality improvement when recording drug allergies. A study in the general population used self-reported methods to collect such information found about a 15% prevalence of antibiotic allergy, which was lower than the 29.8% prevalence noted in our study.⁸

Regarding the most common antibiotic allergies, one study reported allergy to penicillin in the EHR in 12.8% of patients at a major US regional health care system, while 13.1% of patients with SCI had documented allergy to penicillin in our study.⁹ Regarding the other antibiotic classes, the percentage of allergies were higher than those reported in the general population: sulfonamide (9.6% vs 7.4%), fluoroquinolones (4.5% vs 1.3%), and cephalosporins (4.0% vs 1.7%).¹⁰ The EHR appears to capture a much higher rate of antibiotic allergies than that in self-reported studies, such as a study of self-reported allergy in the general adult population in Portugal, where only 4.5% of patients reported allergy to any β-lactam medications.¹⁰

The prevalence of an antibiotic allergy could be affected by the health care setting and sex distribution. For example, the Zhou and colleagues’ study conducted in the Greater Boston area showed higher reported antibiotic rates than those in a study from a Southern California medical group. The higher proportion of tertiary referral patients in that specific network was suggested to be the cause of the difference.^8,9 Our results in the SCI population are more comparable to that in a tertiary setting. This is consistent with the fact that persons with SCI generally have more exposure to antibiotics and consequently a higher reported rate of allergic reactions to antibiotics.

Similarly, the same study in Southern California noted that female patients use more antibiotics than do male patients, thus potentially contributing to higher rates of reported allergy toward all classes of antibiotics.⁸ Our study did not investigate antibiotic allergy by sex; however, the significantly higher proportion of male sex among the veteran population would have impacted these results.

Limitations

Our study was limited as a single-center retrospective study. However, our center is one of the major SCI specialty hubs, and the results should be somewhat reflective of those in the veterans with SCI population. Veterans under the US Department of Veterans Affairs (VA) medical care have the option to seek care or procedures in non-VA facilities. If allergies to antibiotics occurred outside of the VA system, there is no mechanism to automatically merge with the VA EHR allergy list, unless they are later recorded and added to the VA EHR. Thus, there is potential for underreporting.

Drug anaphylaxis incidence was noted to change over time.^4,8,9 For example, a downtrend of reported antibiotic allergy was reported between 1990 and 2013.¹⁰ Our study only reflects an overall prevalence of a single cohort, without demonstration of relationship to time.

Lastly, this study did not aim to differentiate HSRs from other ADRs. This is exactly the point of the study, which investigated the frequency of EHR-recorded antibiotic allergies in our SCI population and reflects the issue with indiscriminate recording of ADRs and HSRs under the umbrella of allergy in the EHR. Further diagnosing true allergies should be considered in the SCI population after weighing the risks and benefits of assessment, aligning with the wishes of the veteran, obtaining informed consent, and addressing the cost-effectiveness of specific tests. We suggest that primary care practitioners work closely with allergy specialists to formulate a mechanism to diagnose various antibiotic allergic reactions, including serum tryptase, epicutaneous skin testing, intradermal skin testing, patch testing, delayed intradermal testing, and drug challenge as appropriate. It is also possible that in cases where very mild reactions/adverse effects of antibiotics were recorded in the EHR, the clinicians and veterans may discuss reintroducing the same antibiotics or proceeding with further testing if necessary. In contrast, the 12% of those with a high risk of severe allergic reactions to penicillin in our study would benefit from allergist evaluation and access to epinephrine auto-injectors at all times. Differentiating true allergy is the only clear way to deter unnecessary avoidance of first-line therapies for antibiotic treatment and avoid promotion of antibiotic resistance.

Future studies can analyze antibiotic allergy based on demographics, including sex and age difference, as well as exploring outpatient vs inpatient settings. Aside from prevalence, we hope to demonstrate antibiotic allergy over time, especially after integration of diagnostic allergy testing, to evaluate the impact to EHR-recorded allergies.

Conclusions

Almost 30% of patients with SCI had a recorded allergy to at least 1 antibiotic. The most common allergy was to penicillin, which is similar to what has previously been reported for the general adult US population. However, only 12% of those with a penicillin allergy were considered high risk of true allergic reactions. Consequently, there are opportunities to examine whether approaches to confirm true reactions (such as skin testing) would help to mitigate unnecessary avoidance of certain antibiotic classes due to mild ADRs, rather than a true allergy, in persons with SCI. This would be an important effort to combat both individual safety concerns and the public health crisis of antibiotic resistance. Given the available evidence, it is reasonable for SCI health care practitioners to discuss the potential risks and benefits of allergy testing with patients with SCI; this maintains a patient-centered approach that can ensure judicious use of antibiotics when necessary.

This is exactly the point of the study, which investigated the frequency of EHR-recorded antibiotic allergies in our SCI population and reflects the issue with indiscriminate recording of ADRs and HSRs under the umbrella of allergy in the EHR. Further diagnosing true allergies should be considered in the SCI population after weighing the risks and benefits of assessment, aligning with the wishes of the veteran, obtaining informed consent, and addressing the cost-effectiveness of specific tests. We suggest that primary care practitioners work closely with allergy specialists to formulate a mechanism to diagnose various antibiotic allergic reactions, including serum tryptase, epicutaneous skin testing, intradermal skin testing, patch testing, delayed intradermal testing, and drug challenge as appropriate. It is also possible that in cases where very mild reactions/adverse effects of antibiotics were recorded in the EHR, the clinicians and veterans may discuss reintroducing the same antibiotics or proceeding with further testing if necessary. In contrast, the 12% of those with a high risk of severe allergic reactions to penicillin in our study would benefit from allergist evaluation and access to epinephrine auto-injectors at all times. Differentiating true allergy is the only clear way to deter unnecessary avoidance of first-line therapies for antibiotic treatment and avoid promotion of antibiotic resistance.

Future studies can analyze antibiotic allergy based on demographics, including sex and age difference, as well as exploring outpatient vs inpatient settings. Aside from prevalence, we hope to demonstrate antibiotic allergy over time, especially after integration of diagnostic allergy testing, to evaluate the impact to EHR-recorded allergies.

Conclusions

Almost 30% of patients with SCI had a recorded allergy to at least 1 antibiotic. The most common allergy was to penicillin, which is similar to what has previously been reported for the general adult US population. However, only 12% of those with a penicillin allergy were considered high risk of true allergic reactions. Consequently, there are opportunities to examine whether approaches to confirm true reactions (such as skin testing) would help to mitigate unnecessary avoidance of certain antibiotic classes due to mild ADRs, rather than a true allergy, in persons with SCI. This would be an important effort to combat both individual safety concerns and the public health crisis of antibiotic resistance. Given the available evidence, it is reasonable for SCI health care practitioners to discuss the potential risks and benefits of allergy testing with patients with SCI; this maintains a patient-centered approach that can ensure judicious use of antibiotics when necessary.

A health system serving three Midwest states must pay millions to the parents of a now 10-year-old boy whose meningitis was misdiagnosed at birth, according to a report in the Star Tribune, among other news outlets.

The story of the jury verdict begins in 2013, when the boy, Johnny Galligan, was just 8 days old.

Alarmed by the newborn’s crying, lack of appetite, and fever, his parents, Alina and Steve Galligan, brought him to Essentia-Health-Ashland Clinic, located in Memorial Medical Center, Ashland, Wisc. There, the baby was seen by Andrew D. Snider, MD, a family physician. Dr. Snider noted the baby’s extreme fussiness and irritability and was concerned that he was being overfed. Without ordering additional tests, the family physician sent the baby home but arranged for the Galligans to be visited by a county nurse the following day.

Her visit raised concerns, as court documents make clear. She contacted Dr. Snider’s office and explained that the baby needed to be seen immediately. After writing a script for reflux and constipation, Dr. Snider arranged for the baby to be taken to his office later that day.

Events proceeded rapidly from this point.

Following an x-ray, Johnny appeared lethargic and in respiratory distress. He was then taken down the hall to Memorial’s emergency department, where doctors suspected a critical bowel obstruction. Arrangements were made for him to be transported by helicopter to Essentia Health, Duluth, Minn. There, doctors saw that Johnny was acidotic and in respiratory failure. Once again, he was rerouted, this time to Children’s Hospital, Minneapolis, where physicians finally arrived at a definitive diagnosis: meningitis.

In 2020, the Galligans filed a medical malpractice claim against several parties, including Dr. Snider, Duluth Clinic (doing business as Essentia Health and Essentia Health–Ashland Clinic), and Memorial Hospital. In their suit, Johnny’s parents alleged that the collective failure to diagnose their son’s severe infection led directly to his permanent brain damage.

But a Bayfield County, Wisconsin, jury didn’t quite see things that way. After deliberating, it dismissed the claim against Dr. Snider and the other named defendants and found the staff of Duluth Clinic to be solely responsible for injuries to Johnny Galligan.

Duluth must pay $19 million to the Galligan family, of which the largest amount ($7,500,00) is to be directed to Johnny’s “future medical expenses and care needs.”

These expenses and costs are likely to be significant. Currently, at 10 years of age, Johnny can’t walk and is confined to a wheelchair. He has serious neurologic problems and is almost completely deaf and blind.

“He’s doing fairly well, which I attribute to his family providing care for him,” says the attorney who represented the Galligans. “They care for him 24/7. They take him swimming and on four-wheeler rides. He’s not bedridden. He has the best possible quality of life he could have, in my opinion.”

In a statement following the verdict, Essentia Health said that, while it felt “compassion for the family,” it stood by the care it had provided in 2013: “We are exploring our options regarding next steps and remain committed to delivering high-quality care to the patients and communities we are privileged to serve.”
 

ED physician found not liable for embolism, jury finds

A Missouri doctor accused of incorrectly treating a woman’s embolism has been found not liable for her death, reports a story in Missouri Lawyers Media.

The woman went to her local hospital’s ED complaining of pain and swelling in her leg. At the ED, an emergency physician examined her and discovered an extensive, visible thrombosis. No other symptoms were noted.

In the past, such a finding would have prompted immediate hospital admission. But the standard of care has evolved. Now, many doctors first prescribe enoxaparin sodium (Lovenox), an anticoagulant used to treat deep-vein thrombosis. This was the option chosen by the Missouri emergency physician to treat his patient. After administering a first dose of the drug, he wrote a script for additional doses; consulted with his patient’s primary care physician; and arranged for the patient to be seen by him, the ED physician, the following day.

At the drugstore, though, the woman became ill, and an emergency medical services crew was alerted. Despite its quick response, the woman died en route to the hospital. No autopsy was later performed, and it was generally presumed that she had died of a pulmonary embolism.

Following the woman’s death, her family sued the emergency physician, alleging that his failure to admit the woman to the hospital most likely delayed treatment that could have saved her life.

The defense pushed back, arguing that the ED physician had followed the standard of care. “Even if she [had] come into the ER with full-blown [pulmonary embolism],” says the attorney representing the emergency physician, “the first thing you do is give Lovenox. It is just one of those rare circumstances where you can do everything right, but the patient can still die.”

The trial jury agreed. After deliberating for more than an hour, it found that the emergency physician was not responsible for the patient’s death.

At press time, there was no word on whether the plaintiffs planned to appeal.

New research is shedding light on how an infection with COVID-19 may reactivate, or even cause, psoriasis. 

 Psoriasis has several well-established triggers, including stress, skin injury, cold or warm air, and allergies. Illnesses like strep throat can also cause a psoriasis flare in some people – and it appears COVID may also do so. “Psoriasis flares have long been associated with bacterial and viral infections, particularly a form of psoriasis called guttate, which is characterized by tons of tiny red scaly bumps all over the body,” said Joel M. Gelfand, MD, a professor of dermatology and epidemiology at the University of Pennsylvania, Philadelphia. “Infection with COVID-19 has been associated with flares of guttate and pustular psoriasis, and even psoriasis that affects 100% of the skin ... in many published case reports.”

Israeli researchers recently found that psoriasis patients have a slightly higher risk of getting COVID,  although they are not at higher risk of hospitalization or death, which could be related to treatment with immune-modulating therapy, which can increase their risk of infections.
 

How could COVID cause psoriasis to flare? 

Psoriasis is an autoimmune condition, and inflammation can cause symptoms.

Investigators for a study from Albany (N.Y.) Medical College and Weirton (Pa.) Medical Center found that people in the study who were already diagnosed with the skin condition had an unexpected flare within a week to a month after testing positive for COVID. New psoriasis after a COVID infection was also found. The researchers think this could be because COVID causes inflammation in the body, which negatively affects previously well-controlled psoriasis. They also think it’s possible that COVID-related inflammation could trigger a genetic tendency to have psoriasis, which may explain why it can appear for the first time after a positive test.

“A viral infection like COVID-19 can signal the release of proinflammatory factors that can appear as rashes, such as with psoriasis.” said Robert O. Carpenter, MD, director of wellness at Texas A&M University in Bryan.
 

What are the symptoms of COVID-related psoriasis?

The signs are the same as those of any form of psoriasis.
 

For a patient with psoriasis, will COVID automatically make it worse?

Not necessarily.

“Psoriasis is a common condition, so people should be aware that new psoriasis that develops may not be related to COVID-19,” said Esther Freeman MD, PhD, director of global health dermatology at Massachusetts General Hospital in Boston.

As with every aspect of COVID, doctors and scientists are still learning about how serious and widespread a problem psoriasis after COVID-19 may be. “We have seen case reports that psoriasis can flare after COVID-19,” said Dr. Freeman, who is also an associate professor of dermatology at Harvard Medical School. “I will say, this has not been a tidal wave – more like sporadic cases here and there. So I do not think psoriasis flares are a major post-COVID finding, nor do they necessarily mean you have long COVID. That being said, we know that many different infections can cause psoriasis flares, and so, in that respect, it’s not that surprising that SARS-CoV-2, like other infections, could trigger a psoriasis flare.”

Could getting COVID more than once cause psoriasis to flare? It’s possible.

“Your body can change after having COVID-19,” said Dr. Carpenter. “We don’t know the long-term implications, but having COVID-19 repeatedly can increase the risk of long COVID, which can cause many systemic changes in your body.” 

Another important point: For patients who take biologics for treating psoriasis, getting vaccinated and boosted for COVID is an important step to take to help protect themselves.
 

Is psoriasis itself a potential symptom of COVID? 

“Yes, but we don’t know the frequency at which this may occur, and a causal relationship is difficult to establish from just case reports,” said Dr. Gelfand, who’s also medical director of the clinical studies unit in the department of dermatology at his university. “Typically, if a patient presents with a flare of psoriasis, particularly guttate, pustular, or erythrodermic forms, an infectious trigger should be considered, and testing for strep and possibly COVID-19 may be appropriate.”

The U.S. Food and Drug Administration (FDA) has approved the first vaccine for respiratory syncytial virus (RSV) in the United States, the agency announced May 3. Arexvy, manufactured by GSK, is the world’s first RSV vaccine for adults aged 60 years and older,the company said in an announcement.

Every year, RSV is responsible for 60,000–120,000 hospitalizations and 6,000–10,000 deaths among U.S. adults older than age, according to the FDA. Older adults with underlying health conditions — such as diabetes, a weakened immune system, or lung or heart disease — are at high risk for severe disease. "Today’s approval of the first RSV vaccine is an important public health achievement to prevent a disease which can be life-threatening and reflects the FDA’s continued commitment to facilitating the development of safe and effective vaccines for use in the United States," said Peter Marks, MD, PhD, director of the FDA’s Center for Biologics Evaluation and Research, in a statement.

The FDA approval of Arexvy was based on a clinical study of approximately 25,000 patients. Half of these patients received Arexvy, while the other half received a placebo. Researchers found that the RSV vaccine reduced RSV-associated lower respiratory tract disease (LRTD) by nearly 83% and reduced the risk of developing severe RSV-associated LRTD by 94%. The most commonly reported side effects were injection site pain, fatigue, muscle pain, headache, and joint stiffness/pain. Ten patients who received Arexvy and four patients who received placebo experienced atrial fibrillation within 30 days of vaccination. The company is planning to assess risk for atrial fibrillation in postmarking studies, the FDA said. The European Medicine Agency’s Committee for Medicinal Products for Human Use recommended approval of Arexvy on April 25, 2023, on the basis of data from the same clinical trial.

GSK said that the U.S. launch of Arexvy will occur sometime in the fall before the 2023/2024 RSV season, but the company did not provide exact dates. "Today marks a turning point in our effort to reduce the significant burden of RSV," said GSK’s chief scientific officer, Tony Wood, PhD, in a company statement. "Our focus now is to ensure eligible older adults in the U.S. can access the vaccine as quickly as possible and to progress regulatory review in other countries."

The company is planning to assess risk for atrial fibrillation in postmarking studies, the FDA said. The European Medicine Agency’s Committee for Medicinal Products for Human Use recommended approval of Arexvy on April 25, 2023, on the basis of data from the same clinical trial.

GSK said that the U.S. launch of Arexvy will occur sometime in the fall before the 2023/2024 RSV season, but the company did not provide exact dates. "Today marks a turning point in our effort to reduce the significant burden of RSV," said GSK’s chief scientific officer, Tony Wood, PhD, in a company statement. "Our focus now is to ensure eligible older adults in the U.S. can access the vaccine as quickly as possible and to progress regulatory review in other countries."

The U.S. Food and Drug Administration (FDA) has approved the first vaccine for respiratory syncytial virus (RSV) in the United States, the agency announced May 3. Arexvy, manufactured by GSK, is the world’s first RSV vaccine for adults aged 60 years and older,the company said in an announcement.

Every year, RSV is responsible for 60,000–120,000 hospitalizations and 6,000–10,000 deaths among U.S. adults older than age, according to the FDA. Older adults with underlying health conditions — such as diabetes, a weakened immune system, or lung or heart disease — are at high risk for severe disease. "Today’s approval of the first RSV vaccine is an important public health achievement to prevent a disease which can be life-threatening and reflects the FDA’s continued commitment to facilitating the development of safe and effective vaccines for use in the United States," said Peter Marks, MD, PhD, director of the FDA’s Center for Biologics Evaluation and Research, in a statement.

The FDA approval of Arexvy was based on a clinical study of approximately 25,000 patients. Half of these patients received Arexvy, while the other half received a placebo. Researchers found that the RSV vaccine reduced RSV-associated lower respiratory tract disease (LRTD) by nearly 83% and reduced the risk of developing severe RSV-associated LRTD by 94%. The most commonly reported side effects were injection site pain, fatigue, muscle pain, headache, and joint stiffness/pain. Ten patients who received Arexvy and four patients who received placebo experienced atrial fibrillation within 30 days of vaccination.

What do green monkeys, fruit bats, and python caves all have in common? All have been implicated in outbreaks as transmission sources of the rare but deadly Marburg virus. Marburg virus is in the same Filoviridae family of highly pathogenic RNA viruses as Ebola virus, and similarly can cause a rapidly progressive and fatal viral hemorrhagic fever.

In the first reported Marburg outbreak in 1967, laboratory workers in Marburg and Frankfurt, Germany, and in Belgrade, Yugoslavia, developed severe febrile illnesses with massive hemorrhage and multiorgan system dysfunction after contact with infected African green monkeys imported from Uganda. Since the first discovery of Marburg virus, there have been over 14 Marburg virus disease (MVD) outbreaks worldwide with nearly 600 cases and case fatality rates of 23%-90%.

The majority of MVD outbreaks have occurred in sub-Saharan Africa, and primarily in three African countries: Angola, the Democratic Republic of Congo, and Uganda. In sub-Saharan Africa, these sporadic outbreaks have had high case fatality rates (up to 80%-90%) and been linked to human exposure to the oral secretions or urinary/fecal droppings of Egyptian fruit bats (Rousettus aegyptiacus), the animal reservoir for Marburg virus. These exposures have primarily occurred among miners or tourists frequenting bat-infested mines or caves, including Uganda’s python cave, where Centers for Disease Control and Prevention investigators have conducted ecological studies on Marburg-infected bats. Person-to-person transmission occurs from direct contact with the blood or bodily fluids of an infected person or contact with a contaminated object (for example, unsterilized needles and syringes in a large nosocomial outbreak in Angola).

On April 6, 2023, the CDC issued a Health Advisory for U.S. clinicians and public health departments regarding two separate MVD outbreaks in Equatorial Guinea and Tanzania. These first-ever MVD outbreaks in both West and East African countries appear to be epidemiologically unrelated. As of March 24, 2023, in Equatorial Guinea, a total of 15 confirmed cases, including 11 deaths, and 23 probable cases, all deceased, have been identified in multiple districts since the outbreak declaration in February 2023. In Tanzania, a total of eight cases, including five deaths, have been reported among villagers in a northwest region since the outbreak declaration in March 2023. While so far cases in the Tanzania MVD outbreak have been epidemiologically linked, in Equatorial Guinea some cases have no identified epidemiological links, raising concern for ongoing community spread.

To date, no cases in these outbreaks have been reported in the United States or outside the affected countries. Overall, the risk of MVD in nonendemic countries, like the United States, is low but there is still a risk of importation. As of May 2, 2023, CDC has issued a Level 2 travel alert (practice enhanced precautions) for Marburg in Equatorial Guinea and a Level 1 travel watch (practice usual precautions) for Marburg in Tanzania. Travelers to these countries are advised to avoid nonessential travel to areas with active outbreaks and practice preventative measures, including avoiding contact with sick people, blood and bodily fluids, dead bodies, fruit bats, and nonhuman primates. International travelers returning to the United States from these countries are advised to self-monitor for Marburg symptoms during travel and for 21 days after country departure. Travelers who develop signs or symptoms of MVD should immediately self-isolate and contact their local health department or clinician.

So, how should clinicians manage such return travelers? In the setting of these new MVD outbreaks in sub-Saharan Africa, what do U.S. clinicians need to know? Clinicians should consider MVD in the differential diagnosis of ill patients with a compatible exposure history and clinical presentation. A detailed exposure history should be obtained to determine if patients have been to an area with an active MVD outbreak during their incubation period (in the past 21 days), had concerning epidemiologic risk factors (for example, presence at funerals, health care facilities, in mines/caves) while in the affected area, and/or had contact with a suspected or confirmed MVD case.

Clinical diagnosis of MVD is challenging as the initial dry symptoms of infection are nonspecific (fever, influenza-like illness, malaise, anorexia, etc.) and can resemble other febrile infectious illnesses. Similarly, presenting alternative or concurrent infections, particularly in febrile return travelers, include malaria, Lassa fever, typhoid, and measles. From these nonspecific symptoms, patients with MVD can then progress to the more severe wet symptoms (for example, vomiting, diarrhea, and bleeding). Common clinical features of MVD have been described based on the clinical presentation and course of cases in MVD outbreaks. Notably, in the original Marburg outbreak, maculopapular rash and conjunctival injection were early patient symptoms and most patient deaths occurred during the second week of illness progression.

Supportive care, including aggressive fluid replacement, is the mainstay of therapy for MVD. Currently, there are no Food and Drug Administration–approved antiviral treatments or vaccines for Marburg virus. Despite their viral similarities, vaccines against Ebola virus have not been shown to be protective against Marburg virus. Marburg virus vaccine development is ongoing, with a few promising candidate vaccines in early phase 1 and 2 clinical trials. In 2022, in response to MVD outbreaks in Ghana and Guinea, the World Health Organization convened an international Marburg virus vaccine consortium which is working to promote global research collaboration for more rapid vaccine development.

In the absence of definitive therapies, early identification of patients with suspected MVD is critical for preventing the spread of infection to close contacts. Like Ebola virus–infected patients, only symptomatic MVD patients are infectious and all patients with suspected MVD should be isolated in a private room and cared for in accordance with infection control procedures. As MVD is a nationally notifiable disease, suspected cases should be reported to local or state health departments as per jurisdictional requirements. Clinicians should also consult with their local or state health department and CDC for guidance on testing patients with suspected MVD and consider prompt evaluation for other infectious etiologies in the patient’s differential diagnosis. Comprehensive guidance for clinicians on screening and diagnosing patients with MVD is available on the CDC website at https://www.cdc.gov/vhf/marburg/index.html.

The U.S. government plans to no longer require federal workers or international air travelers to be vaccinated for COVID-19, the Biden administration has announced. 

The move means vaccines will no longer be required for workers who are federal employees, federal contractors, Head Start early education employees, workers at Medicare-certified health care facilities, and those who work at U.S. borders. International air travelers will no longer be required to prove their vaccination status. The requirement will be lifted at the end of the day on May 11, which is also when the federal public health emergency declaration ends.

“While vaccination remains one of the most important tools in advancing the health and safety of employees and promoting the efficiency of workplaces, we are now in a different phase of our response when these measures are no longer necessary,” an announcement from the White House stated.

White House officials credited vaccine requirements with saving millions of lives, noting that the rules ensured “the safety of workers in critical workforces including those in the healthcare and education sectors, protecting themselves and the populations they serve, and strengthening their ability to provide services without disruptions to operations.”

More than 100 million people were subject to the vaccine requirement, The Associated Press reported. All but 2% of those covered by the mandate had received at least one dose or had a pending or approved exception on file by January 2022, the Biden administration said, noting that COVID deaths have dropped 95% since January 2021 and hospitalizations are down nearly 91%.

In January, vaccine requirements were lifted for U.S. military members.

On the government-run website Safer Federal Workforce, which helped affected organizations put federal COVID rules into place, agencies were told to “take no action to implement or enforce the COVID-19 vaccination requirement” at this time.

WASHINGTON – Approximately 70% of children with febrile urinary tract infections receive guideline-adherent follow-up imaging from primary care, based on data from 118 individuals.

“Timely imaging is recommended after febrile UTI (fUTI) in young children to identify treatable urologic conditions,” wrote Jonathan Hatoun, MD, of Boston Children’s Hospital, and colleagues in a poster presented at the Pediatric Academic Societies annual meeting.

The American Academy of Pediatrics (AAP) currently recommends renal-bladder ultrasound (RBUS) after fUTI with voiding cystourethrogram (VCUG) after abnormal RBUS or second fUTI, but data on clinician adherence to these recommendations are limited, the researchers said.

To characterize practice patterns regarding fUTI, the researchers reviewed data from children younger than 24 months of age with fUTI who were treated at a primary care network in Massachusetts in 2019. The definition of fUTI was temperature of 38° C or higher, positive urinalysis, and more than 50,000 CFU on urine culture. The median age of the patients was 9 months; 84% were female.

In a multivariate analysis, post-UTI imaging followed the AAP guidelines in 82 cases (69.5%). The main reasons for nonadherence were lack of RBUS in 21 patients, VCUG despite normal RBUS in 9 patients, no VCUG after abnormal RBUS in 4 patients, and no VCUG after a second fUTI in 2 patients.

Overall, nonadherence was a result of not ordering a recommended study in 23% of cases (errors of omission) and ordering an unnecessary study in 8% of cases (errors of commission).

Commercial insurance, larger number of providers in practice, and younger provider age were significant independent predictors of adherence (odds ratios 2.82, 1.38, and 0.96, respectively).

The findings were limited by the use of data from a single center; however, the results suggest that targeted training may improve guideline adherence, the researchers wrote. Additional research and quality improvement studies are needed to understand and address the impact of insurance on guideline adherence for imaging after febrile UTIs, they noted.
 

Provider education is essential to continued quality of care

When it comes to febrile UTIs, “it is important to stay focused on the quality of care being provided, as opposed to the usual benchmark of quantity of care,” Tim Joos, MD, a Seattle-based clinician with a combination internal medicine/pediatrics practice, said in an interview.

“This is a very simple but interesting study on provider compliance with practice guidelines,” said Dr. Joos, who was not involved in the study. “I was surprised that the providers did so well in ordering the correct imaging in 70% of the cases,” he said.

 Of particular interest, Dr. Joos noted, was that “the authors also showed that older providers and those working in smaller practices are less likely to comply with this particular imaging guideline. This can be summed up as the ‘I didn’t know the guideline’ effect.”

To improve quality of care, “more research and effort should be directed at updating providers when strong new evidence changes previous practices and guidelines,” Dr. Joos told this news organization.

The study received no outside funding. The researchers and Dr. Joos had no financial conflicts to disclose.

The definition of fUTI was temperature of 38° C or higher, positive urinalysis, and more than 50,000 CFU on urine culture. The median age of the patients was 9 months; 84% were female.

In a multivariate analysis, post-UTI imaging followed the AAP guidelines in 82 cases (69.5%). The main reasons for nonadherence were lack of RBUS in 21 patients, VCUG despite normal RBUS in 9 patients, no VCUG after abnormal RBUS in 4 patients, and no VCUG after a second fUTI in 2 patients.

Overall, nonadherence was a result of not ordering a recommended study in 23% of cases (errors of omission) and ordering an unnecessary study in 8% of cases (errors of commission).

Commercial insurance, larger number of providers in practice, and younger provider age were significant independent predictors of adherence (odds ratios 2.82, 1.38, and 0.96, respectively).

The findings were limited by the use of data from a single center; however, the results suggest that targeted training may improve guideline adherence, the researchers wrote. Additional research and quality improvement studies are needed to understand and address the impact of insurance on guideline adherence for imaging after febrile UTIs, they noted.
 

Provider education is essential to continued quality of care

When it comes to febrile UTIs, “it is important to stay focused on the quality of care being provided, as opposed to the usual benchmark of quantity of care,” Tim Joos, MD, a Seattle-based clinician with a combination internal medicine/pediatrics practice, said in an interview.

“This is a very simple but interesting study on provider compliance with practice guidelines,” said Dr. Joos, who was not involved in the study. “I was surprised that the providers did so well in ordering the correct imaging in 70% of the cases,” he said.

 Of particular interest, Dr. Joos noted, was that “the authors also showed that older providers and those working in smaller practices are less likely to comply with this particular imaging guideline. This can be summed up as the ‘I didn’t know the guideline’ effect.”

To improve quality of care, “more research and effort should be directed at updating providers when strong new evidence changes previous practices and guidelines,” Dr. Joos told this news organization.

The study received no outside funding. The researchers and Dr. Joos had no financial conflicts to disclose.
