Psychiatric disorders often impair antiretroviral adherence in perinatally HIV-infected teens
DURBAN, SOUTH AFRICA – Adolescents who were perinatally infected with HIV have a high prevalence of selected psychiatric disorders that impede their adherence to antiretroviral therapy, Claude Ann Mellins, PhD, reported at the 21st International AIDS Conference.
Those psychiatric diagnoses were predictive of viremia over the ensuing 2-3 years in a new analysis from the ongoing Child and Adolescent Self-Awareness and Health (CASAH) study, according to Dr. Mellins, professor of medical psychology at Columbia University, New York, and codirector of CASAH.
The clinical implications of the CASAH findings are clear, she added. “Assessing and treating specific categories of psychiatric and substance abuse problems may enhance efforts to improve adherence and prevent poor health outcomes in these adolescents and young adults, who are especially vulnerable due to their very challenging circumstances,” Dr. Mellins said.
CASAH is a longitudinal study of perinatally HIV-infected and perinatally HIV-exposed but uninfected New York City youth. They were enrolled during 2003-2008, when they were 9-16 years old. They and their caregivers undergo detailed psychosocial interviews every 12-18 months. The goal is to identify risk factors as well as protective factors influencing their behavioral health outcomes, the clinical psychologist explained.
She reported on 179 perinatally infected adolescents who were at least 13 years old at the first of their three interviews conducted over a 2.7-year period. Of note, 53% of them met Diagnostic Interview Schedule for Children (DISC-IV) criteria for one or more psychiatric diagnoses at all three time points. The pattern of psychopathology was somewhat different from that previously described in adults with HIV, who have been studied much more extensively than perinatally infected teens.
“Much of the literature on adults has focused on depression and mood disorders as predictors of poor health outcomes. Our data suggest that among youth, disruptive behavioral disorders – things like [attention-deficit/hyperactivity disorder], conduct disorder, or oppositional defiant disorder – may be just as important, if not more so. Substance abuse was also a critical factor,” Dr. Mellins said.
In a cross-sectional multivariate logistic regression analysis, a behavior disorder diagnosed at the first interview was associated with a 2.57-fold increased likelihood of contemporaneous viremia as evidenced by a plasma HIV RNA viral load greater than 1,000 copies/mL, and with a threefold increased likelihood of self-reported missed doses of antiretroviral medications during the previous week.
Anxiety disorder was the most common psychiatric diagnosis at the initial interview, followed by disruptive behavior disorder and substance use disorder. A diagnosis of any psychiatric disorder at the time of the first interview was associated with a significantly increased risk of viremia across the next 2.7 years. Forty-seven percent of subjects had viremia at 2.7 years of follow-up, reflective of chronic suboptimal medication adherence.
She noted that the pattern of psychiatric disorders in perinatally infected patients shifts between adolescence and young adulthood.
“By the time perinatally infected adolescents become young adults, I will say that anxiety and mood disorders become much more prevalent. But the number of psychiatric problems actually goes down by young adulthood,” according to Dr. Mellins.
Indeed, in another CASAH analysis she presented at AIDS 2016, this one involving 136 perinatally infected young adults and 86 perinatally exposed but uninfected controls, the vast majority living in impoverished communities, there was no difference between the two groups in rates of psychiatric or substance use disorders, although the 27% prevalence of substance use disorders is higher than that found in the age-matched general population.
Eighty-four percent of the perinatally infected 18- to 28-year-olds had graduated from high school, 94% were in a stable housing situation, 59% were currently working or in school, 54% were paying rent, and 95% reported ever being in a romantic relationship. Rates were similar in the perinatally exposed but uninfected group with the exception that these individuals were less likely to be paying rent.
“In spite of substantive risks, there is a relatively large portion of both groups with positive behavioral health outcomes, achieving normative young adult transition milestones. We need to understand why. Identification of protective factors conferring resilience can inform evidence-based prevention efforts, which are critical given the staggering numbers of children and young adolescents worldwide affected by HIV who will be transitioning to adulthood,” she said.
Dr. Mellins said the CASAH findings constitute a persuasive argument in favor of integrating mental health as a component of HIV care.
“Young people don’t always go to mental health appointments that are separate from medical care, so integrating mental health as a component of HIV care might be one of the most effective ways to identify and treat mental health problems in infected youth while simultaneously improving medication adherence and health outcomes,” Dr. Mellins said.
The ongoing CASAH study is funded by the National Institute of Mental Health. Dr. Mellins reported having no relevant financial conflicts.

A few 20-shot sessions might be enough for deoxycholic acid
NEWPORT BEACH, CALIF. – It’s unclear how well deoxycholic acid (Kybella) will work in the clinic because doctors and patients are generally opting for fewer injections and fewer treatment sessions than were evaluated in phase III studies, according to Lawrence Bass, MD.
The fat cytolytic was approved in 2015 for shrinking double chins, with up to six 50-injection sessions. In trials, patients tended to get more than 40 shots in their first two sessions and more than 30 in subsequent sessions. At that dosing, 40.5% of patients in one trial and 46% in another lost at least 10% of their submental volume on MRI, according to Food and Drug Administration review documents.
However, at the Summit in Aesthetic Medicine, Dr. Bass, a plastic surgeon in New York City, said that, in clinical practice, patients are typically being treated with 20 injections for two or three sessions – partly because of cost. “This product costs $300 for each 2 mL vial, which means in a typical 20-injection treatment, you use $600 of material,” he noted. An average treatment session in Manhattan costs patients about $1,500. In other parts of the country, sessions are probably around $1,200 each, he added.
Also, the necks of patients enrolled in trials “had to be pretty big, but the necks we are probably going to treat with this are the smaller and medium ones. The big ones are just going to do liposuction or something else,” he said. Given all the variables, “we don’t know how well the study experience is going to match clinical experience.”
Dr. Bass treated his first postapproval patient, a 52-year-old woman, with two 20-injection treatment sessions 2 months apart. “The fat definitely cleaned out” and her skin looked a bit tighter, but it’s tough to know if her skin truly tightened or simply draped flatter, he said.
FDA labeling notes that “the safe and effective use of Kybella for the treatment of subcutaneous fat outside the submental region has not been established and is not recommended,” but this advice is unlikely to keep doctors from trying it in off-label areas.
One issue is that “almost every other area is a whole lot bigger” than a double chin, Dr. Bass said. Treating a tummy with 50 injections six to eight times, for example, would cost patients $12,000-$15,000, which is “a whole lot more than lipo,” he added.
Also, administering more than 50 injections at a time for a larger area is not possible because of toxicity. Trying to get around that limit and cut costs by diluting deoxycholic acid or spacing the injections farther apart doesn’t seem to be an option, since phase II testing showed a loss of efficacy with that approach.
Dr. Bass tried deoxycholic acid on a woman with leftover tummy bulges following liposuction. After two 40-injection sessions, “there was still a little shape there, so I don’t think I’ll be doing that again,” he said at the meeting, which is held by Global Academy for Medical Education. Global Academy and this news organization are owned the same company.
Gynecomastia, meanwhile, would probably require too many shots, and the jowl, another potential target, is too close to the marginal mandibular branch of the facial nerve, “so you are not supposed to inject there,” Dr. Bass said. Diluted deoxycholic acid might be an option for bulging periorbital fat, “but I am going to let somebody who is braver than me try that for a while before I go there.”
Dr. Bass is an investigator and speaker for Cynosure, an investigator for Endo Pharmaceuticals and Neothetics, and an advisor to Merz. He participated in phase III testing of deoxycholic acid.
The indication approved for deoxycholic acid is “for improvement in the appearance of moderate to severe convexity or fullness associated with submental fat in adults.”

EXPERT ANALYSIS FROM THE SUMMIT IN AESTHETIC MEDICINE
Veteran Homelessness Drops 47% Since 2010
In the latest Department of Housing and Urban Development annual Point-in-Time (PIT) estimate of America’s homeless population, President Barak Obama revealed that since 2010 the rate of homelessness among veterans has dropped 47%. The January count found 13,000 homeless veterans, although the count fell well short of the President’s pledge to completely eliminate homelessness by 2016. “We will not stop until every veteran who fought for America has a home in America,” President Obama told the national Disabled American Veterans (DAV) convention on August 1. “This is something we’ve got to get done.”
“The dramatic decline in veteran homelessness is the result of the Obama administration’s investments in permanent supportive housing solutions, such as HUD-VASH [Housing and Urban Development-VA Supportive Housing] and Supportive Services for Veteran Families programs, extensive community partnerships, coordinated data and outreach, and other proven strategies that put Veterans first,” said VA Secretary Robert A. McDonald in a release. According to the VA, Virginia, Connecticut and 27 cities and towns across the country have “effectively ended” veteran homelessness.
In the DAV speech, President Obama also touted a number of VA health care programs, ranging from rural telehealth initiatives to increased funding for prosthetics and access to women’s health providers at all VA clinics. Pointing out that VA funding has increased during his administration, the President noted that “We’ve made VA benefits available to more than 2 million veterans who didn’t have them before.” The President also pointed out that veterans can apply for VA health care “…from any device, including your smartphone—simple, easy, in as little as 20 minutes.”
The White House also announced that the Million Veteran Program (MVP) had reached a new milestone with 500,000 veterans enrolled. About 62% of MVP enrollees reported a current or past diagnosis of high blood pressure and about one-third reported tinnitus. Also, nearly one-third, or 32%, of veterans present with a history or current diagnosis of cancer. “We believe MVP will accelerate our understanding of disease detection, progression, prevention and treatment by combining this rich clinical, environmental and genomic data,” said VA Under Secretary for Health David J. Shulkin, MD, in a statement. “VA has a deep history of innovation and research. The MVP will allow the nation’s top researchers to perform the most cutting-edge science to treat some of the nation’s most troubling diseases.”
“What this does is it gives us a better understanding of genetics, which will allow us to improve treatments for things like traumatic brain injury and posttraumatic stress, and diabetes, and cancer,” President Obama told the DAV audience. “And that won’t just help veterans. It will help all Americans. And it’s just one more example of how our veterans keep serving our country even after they come home.”
While Acknowledging the VA’s challenges to meet the needs of veterans, President Obama was insistent that VA care was essential for veterans. “Study after study shows that in many areas, like mental health, the quality of care at the VA is often better than in private care,” he told the DAV members. “So let’s listen to our veterans, who are telling us: Don’t destroy VA health care. Fix it and make it work, but don’t break our covenant with our veterans.”

Also, nearly one-third, or 32%, of veterans present with a history or current diagnosis of cancer. “We believe MVP will accelerate our understanding of disease detection, progression, prevention and treatment by combining this rich clinical, environmental and genomic data,” said VA Under Secretary for Health David J. Shulkin, MD, in a statement. “VA has a deep history of innovation and research. The MVP will allow the nation’s top researchers to perform the most cutting-edge science to treat some of the nation’s most troubling diseases.”
“What this does is it gives us a better understanding of genetics, which will allow us to improve treatments for things like traumatic brain injury and posttraumatic stress, and diabetes, and cancer,” President Obama told the DAV audience. “And that won’t just help veterans. It will help all Americans. And it’s just one more example of how our veterans keep serving our country even after they come home.”
While Acknowledging the VA’s challenges to meet the needs of veterans, President Obama was insistent that VA care was essential for veterans. “Study after study shows that in many areas, like mental health, the quality of care at the VA is often better than in private care,” he told the DAV members. “So let’s listen to our veterans, who are telling us: Don’t destroy VA health care. Fix it and make it work, but don’t break our covenant with our veterans.”

Gene therapy reduces need for FIX prophylaxis

ORLANDO—The gene therapy AMT-060 can reduce the need for factor IX (FIX) prophylaxis in patients with severe hemophilia B, results of a phase 1/2 study suggest.
All of the patients treated in the low-dose cohort of this study have had sustained improvements in their disease phenotype and continue to maintain durable levels of FIX gene activity for up to 39 weeks post-treatment.
Four of the 5 patients were able to discontinue prophylactic FIX infusions.
In addition, AMT-060 was considered well-tolerated. There were 2 serious adverse events, but both were temporary. And none of the patients developed FIX inhibitors.
These data were presented at the World Federation of Hemophilia 2016 World Congress.* The research is sponsored by uniQure.
“I am very encouraged by the stability of increased FIX activity of AMT-060 and the significant reduction in required infusions of factor replacement,” said study investigator Wolfgang Miesbach, MD, of the University of Frankfurt in Germany.
“This effect is particularly important because it is seen in severe patients with established joint disease who experienced a high frequency of joint bleeds despite intense use of prophylactic FIX prior to study entry.”
Patients and treatment
AMT-060 consists of a codon-optimized wild-type FIX gene cassette, the LP1 liver promoter, and an AAV5 viral vector manufactured by uniQure using its proprietary insect cell-based technology platform.
In this phase 1/2 trial, Dr Miesbach and his colleagues are testing AMT-060 in 10 patients. All patients had severe or moderately severe hemophilia at baseline, including documented FIX levels less than 1% to 2% of normal, and required chronic infusions of prophylactic or on-demand FIX therapy at the time of enrollment.
Each patient received a 1-time, 30-minute, intravenous dose of AMT-060, without the use of corticosteroids. Five patients received AMT-060 at 5x1012 gc/kg, and 5 received AMT-060 at 2x1013 gc/kg.
Dr Miesbach presented results observed in the low-dose cohort. Patients in the high-dose cohort are still in the early stages of follow-up.
Most patients in the low-dose cohort were older than 50 years of age (range, 35-72). Four patients had severe hemophilia B, and 4 had advanced joint disease. All of the patients had frequent bleeding episodes, despite receiving once- or twice-weekly FIX prophylaxis.
Efficacy
For all 5 patients in the low-dose cohort, the mean annualized total FIX usage declined 75% after treatment with AMT-060.
“The majority of patients in this low-dose cohort of AMT-060 are showing FIX activity in the range of 5% of normal, and clinical experience has shown that patients in this range generally do not require prophylactic factor replacement and have a very low frequency of spontaneous joint bleeding episodes,” Dr Miesbach said.
Four patients discontinued prophylactic therapy. The 1 patient who remained on prophylactic therapy has sustained an improved disease phenotype and also required materially less FIX concentrate after treatment with AMT-060.
Through up to 9 months of follow-up, the mean steady-state FIX activity for the 4 patients who discontinued prophylactic FIX therapy was 5.4% of normal, with a range from 3.1% to 6.7% of normal. These patients had a mean reduction in annualized total FIX usage of 82%.
Safety and immunogenicity
Two patients experienced serious adverse events. One patient had self-limiting fever in the first 24 hours after receiving AMT-060.
The other patient had a transient elevation of alanine aminotransferase (ALT) that was responsive to tapering prednisolone (60 mg/day start dose) without loss of FIX activity. At baseline, this patient’s ALT was 26 IU/L. It hit a peak of 61 IU/L at week 10, but values returned to baseline levels within 2 weeks of treatment.
As expected, all of the patients developed anti-AAV5 antibodies after week 1. None of the patients developed inhibitory antibodies against FIX.
There was no evidence of sustained AAV5 capsid-specific T-cell activation, although 1 patient had transient T-cell activation slightly above the positive threshold at 1 time point. This patient did not have ALT elevation.

Microneedle system could replace blood draws, team says

Sahan Ranamukhaarachchi
A new microneedle drug monitoring system could one day replace invasive blood draws, according to researchers.
The system consists of a small, thin patch that is pressed against a patient’s arm during medical treatment and measures drugs in the bloodstream painlessly without drawing any blood.
The tiny projections on this patch resemble hollow cones and don’t pierce the skin like a standard hypodermic needle.
The researchers described this system in Scientific Reports.
“Many groups are researching microneedle technology for painless vaccines and drug delivery,” said study author Sahan Ranamukhaarachchi, a PhD student at the University of British Columbia (UBC) in Vancouver, British Columbia, Canada. “Using them to painlessly monitor drugs is a newer idea.”
The microneedle system Ranamukhaarachchi and his colleagues created was developed to monitor the antibiotic vancomycin. Patients taking vancomycin must be closely monitored because the drug can cause life-threatening side effects, so the patients undergo 3 to 4 blood draws per day.
The researchers discovered they could use fluid found just below the outer layer of skin, instead of blood, to monitor levels of vancomycin in the bloodstream.
The microneedle patch collects a tiny amount of the fluid, less than 1 nL, and a reaction occurs on the inside of the microneedles that can be detected using an optical sensor. This allows the user to quickly determine the concentration of vancomycin.
“This is probably one of the smallest probe volumes ever recorded for a medically relevant analysis,” said study author Urs Häfeli, PhD, of UBC.
This microneedle drug monitoring system was developed out of a research collaboration between Dr Häfeli and Boris Stoeber, PhD, also of UBC. The system is being commercialized by the UBC spin-off Microdermics Inc.

HDAC inhibitor granted breakthrough designation
Image by Eric Smith
The US Food and Drug Administration (FDA) has granted breakthrough therapy designation for the histone deacetylase (HDAC) inhibitor pracinostat to be used in combination with azacitidine to treat newly diagnosed acute myeloid leukemia (AML) patients who are 75 and older or unfit for intensive chemotherapy.
The FDA’s breakthrough designation is intended to expedite the development and review of new therapies for serious or life-threatening conditions.
To earn the designation, a treatment must show encouraging early clinical results demonstrating substantial improvement over available therapies with regard to a clinically significant endpoint, or it must fulfill an unmet need.
The breakthrough therapy designation for pracinostat is supported by data from a phase 2 study of the HDAC inhibitor in combination with azacitidine in elderly patients with newly diagnosed AML who were not candidates for induction chemotherapy.
Detailed results from this trial were presented at the 20th Congress of the European Hematology Association last year. The research was sponsored by MEI Pharma, the company developing pracinostat.
The study included 50 AML patients who had a median age of 75 (range, 66-84).
The patients received pracinostat at 60 mg orally on days 1, 3, and 5 of each week for 21 days of each 28-day cycle. They received azacitidine subcutaneously or intravenously on days 1-7 or days 1-5 and 8-9 (per site preference) of each 28-day cycle.
According to updated data from MEI Pharma, the complete response rate was 42% (n=21), and the median overall survival was 19.1 months.
The company said these data compare favorably to a phase 3 study of azacitidine (AZA-AML-0011), which showed a median overall survival of 10.4 months with azacitidine alone and a complete response rate of 19.5% in a similar patient population.
The combination of pracinostat and azacitidine was thought to be well tolerated overall, with no unexpected toxicities. The most common grade 3-4 treatment-emergent adverse events included febrile neutropenia, thrombocytopenia, anemia, and fatigue.

A 65‐year‐old immunocompetent man with a history of obesity, diabetes, and chronic lower extremity edema presents to the emergency room with a 1‐day history of right lower extremity pain and increased swelling. He reports no antecedent trauma and states he just noticed the symptoms that morning. On examination, he appears generally well.

BACKGROUND
The term skin and soft tissue infection (SSTI) includes a heterogeneous group of infections including cellulitis, cutaneous abscess, diabetic foot infections, surgical site infections, and necrotizing soft tissue infections. As a group, SSTIs are the second most common type of infection in hospitalized adults in the United States behind pneumonia and result in more than 600,000 admissions per year.[1] The current guideline on SSTIs by the Infectious Disease Society of America (IDSA) makes the distinction between purulent and nonpurulent soft tissue infections based on the presence or absence of purulent drainage or abscess and between mild, moderate, and severe infections based on the presence and severity of systemic signs of infection.[2] Figure 1 provides an overview of the IDSA recommendations.
THE PROBLEM: OVERUSE OF BROAD‐SPECTRUM ANTIBIOTICS
Studies over the past decade have shown that the majority of patients hospitalized with SSTI receive broad‐spectrum antibiotics, usually with combinations of antibiotics active against gram‐positive (including methicillin‐resistant Staphylococcus aureus [MRSA]), gram‐negative (often including Pseudomonas aeruginosa), and anaerobic organisms. Broad‐spectrum treatment occurs despite guidelines from the IDSA, which state that the most common pathogens for nonpurulent cellulitis are ‐hemolytic streptococci, which remain susceptible to penicillin.[2, 3] One multicenter study of hospitalized adults with nonpurulent cellulitis, for example, reported that 85% of patients received therapy effective against MRSA (primarily vancomycin), 61% received broad gram‐negative coverage (primarily ‐lactam with ‐lactamase inhibitor), and 74% received anaerobic coverage.[4] Another multicenter study reported that the most common antibiotics given for cellulitis (excluding cases associated with cutaneous abscess) were vancomycin (60%), ‐lactam/‐lactamase combinations (32%), and clindamycin (19%). Only 13% of patients with cellulitis were treated with cefazolin, and only 1.1% of patients were treated with nafcillin or oxacillin.[5] According to the Centers for Disease Control and Prevention, unnecessary antibiotic use is associated with increased cost, development of antibiotic resistance, and increased rates of Clostridium difficile.[6]
The current use of broad‐spectrum antibiotics for nonpurulent cellulitis is likely due to several factors, including the emergence of community‐associated (CA)‐MRSA, confusion due to the heterogeneity of SSTI, and the limited data regarding the microbiology of nonpurulent cellulitis. The resulting uncertainty about cellulitis has been termed an existential crisis for the treating physician and is likely the single biggest factor behind the out‐of‐control prescribing.[7]
The Emergence of CA‐MRSA
Over the past decade, numerous studies have reported the increasing frequency of CA‐MRSA soft tissue infections, predominantly with the pulsed‐field gel electrophoresis type USA‐300. Originally, MRSA infections were limited to nosocomial infections. Subsequent multicenter studies from the United States have shown that CA‐MRSA is the most frequent pathogen isolated from purulent soft tissue infections presenting to emergency rooms[8] and the most frequent pathogen isolated from SSTI specimens in labs.[9] Many authors have therefore concluded that empiric antibiotics for SSTI should include coverage for MRSA.[8, 9]
Heterogeneity of SSTI
As already discussed, the term SSTI is an umbrella term that encompasses several types of clinically distinct infections. The only commonality between the SSTI is that that they all involve the skin and soft tissues in some way. Diabetic foot infections, cutaneous abscesses, surgical site infections, and nonpurulent cellulitis have different hosts, pathophysiology, clinical presentations, and microbiology. At one end of the spectrum is the cutaneous abscess, which is readily culturable through incision and drainage. At the other end of the spectrum is cellulitis, which is typically nonculturable. Unfortunately, studies of SSTI tend to lump all of these entities together when reporting microbiology. The landmark study by Moran et al., for example, described the microbiology of purulent soft tissue infections presenting to a network of emergency rooms across the county. Although all patients had by definition purulent infections, and 81% were abscesses, the authors made broad conclusions about skin and soft tissue infections in general and recommended antimicrobials effective against MRSA for empiric coverage for SSTIs.[8]
Uncertainty About the Microbiology of Nonpurulent Cellulitis
What then is the microbiology of nonpurulent cellulitis? As stated in the 2005 and 2014 IDSA guidelines, traditional teaching remains that nonpurulent cellulitis is primarily due to ‐hemolytic streptococci.[2, 3] Studies using needle aspiration have yielded conflicting results, although a systematic review of these studies concluded that S aureus was the most common pathogen.[10] On the other hand, a systematic review of positive blood cultures of patients identified as having cellulitis found that 61% were due to ‐hemolytic streptococci, and only 15% were due to S aureus.[11] Both reviews, however, comment on the limited quality of the included studies. Ultimately, because nonpurulent soft tissue infections are basically nonculturable, their true microbiologic etiology remains uncertain. Given this uncertainty, as well as the impressive evidence for CA‐MRSA causing cutaneous abscesses, along with the confusion about types of SSTI, it is not surprising that front‐line clinicians have resorted to prescribing broad‐spectrum antibiotics.
THE SOLUTION: NARROW‐SPECTRUM ANTIBIOTICS FOR MOST
Although studies of the microbiology of cellulitis remain inconclusive, several recent clinical trials have indicated that treatment with antimicrobials limited to ‐hemolytic streptococci and methicillin‐susceptible S aureus (MSSA) are as effective as antimicrobials against MRSA. A prospective study from 2010 of consecutive hospitalized adults with nonpurulent cellulitis found that 73% had serologic evidence for streptococcal infection, and overall 95.8% responded to cefazolin monotherapy.[12] More recently, a study of emergency room patients with nonpurulent cellulitis randomized patients to cephalexin alone or cephalexin plus trimethoprim‐sulfamethoxazole. These authors found no difference in response rates and concluded that the addition of anti‐MRSA therapy (trimethoprim‐sulfamethoxazole, in this study) for uncomplicated cellulitis was unnecessary.[13] This later study is the only randomized controlled study to assess the need for MRSA coverage for cellulitis, and the answer for outpatients, at least, is that MRSA coverage is unnecessary. Both of these studies are cited by the IDSA guideline from 2014, which recommends antibiotics for mild‐moderate cellulitis to be limited to antimicrobials effective against ‐hemolytic streptococci and MSSA. The guideline specifically does not recommend routinely treating for MRSA, gram‐negative, or anaerobic organisms citing lack of benefit as well as risks of antibiotic resistance and C difficile infection. A recent study from the University of Utah reported the development of a cellulitis order set, which included a pathway for nonpurulent cellulitis based on the use of cefazolin. These authors reported that the use of the pathway was associated with a 59% decrease in the use of broad‐spectrum antibiotics, a 23% decrease in pharmacy costs, a 13% decrease in total facility cost, with no change in hospital length of stay or readmission rate.[14] One important caveat to the use of clinical pathways is that they are often underused. In the study from the University of Utah, for example, only 55% of eligible patients had the clinical pathway ordered.
WHEN BROAD‐SPECTRUM ANTIBIOTICS ARE RECOMMENDED
The IDSA does recommend empiric broad‐spectrum antibiotics with combination gram‐positive and gram‐negative coverage in several situations, including severe infections in which necrotizing soft tissue infection is suspected, animal bites, immersion injuries, as well as for severely immunocompromised patients or those who have failed limited spectrum antibiotics. Additionally, the IDSA recommends antimicrobials effective against MRSA for purulent infections with systemic signs of inflammation as well as severe nonpurulent infections or those associated with penetrating trauma, injection drug use, and nasal colonization with MRSA (Figure 1).
RECOMMENDATIONS
Our patient has no associated purulence and no abscess and therefore has nonpurulent cellulitis. Based on his mild tachycardia and leukocytosis but intact immune system and lack of suspicion for necrotizing soft tissue infection, he would be classified as moderate‐severity cellulitis by the IDSA. In patients hospitalized with nonpurulent cellulitis who are not severely immunocompromised or severely ill and for whom necrotizing soft tissue infection is not suspected:
- Antibiotics should be directed at ‐hemolytic streptococci and MSSA, with 1 of the suggested antibiotics by the IDSA including penicillin, ceftriaxone, cefazolin, or clindamycin.
- Antibiotics effective against MRSA should be limited to situations described by the IDSA.
- If the cellulitis has not improved within 48 hours, then consider broader‐spectrum antibiotics.
- Hospitals should strongly consider implementation of a cellulitis pathway based on the IDSA recommendations to improve antibiotic stewardship as well as costs.
