Frailty, Not Just Advanced Age, Affects ANCA Vasculitis Outcomes
TOPLINE:
Older adults with antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis face a higher risk for end-stage renal disease or mortality and severe infections. However, frailty, more than age, predicts severe infections within 2 years of diagnosis.
METHODOLOGY:
- Researchers conducted a retrospective cohort study using data from the Mass General Brigham ANCA-associated vasculitis cohort in the United States.
- They included 234 individuals (median age, 75 years) with incident ANCA-associated vasculitis who were treated from January 2002 to December 2019.
- Baseline frailty was measured using a claims-based frailty index, with data collected in the year before treatment initiation; individuals were categorized as those who were nonfrail, prefrail, mildly frail, and moderately to severely frail.
- Frailty, either mild or moderate to severe, was noted in 44 of 118 individuals aged ≥ 75 years and in 25 of 116 individuals aged 65-74 years.
- The outcomes of interest were the incidences of end-stage renal disease or death and severe infections within 2 years of diagnosis. The association of age and frailty with clinical outcomes was assessed in those aged 65-74 years and ≥ 75 years.
TAKEAWAY:
- Frailty was a significant predictor of severe infections within 2 years of ANCA-associated vasculitis diagnosis (adjusted hazard ratio [aHR], 8.46; 95% CI, 3.95-18.14), showing a stronger association than seen for chronological age ≥ 75 years (aHR, 2.52; 95% CI, 1.26-5.04).
- The incidence of severe infections was higher in those with vs without frailty in the age groups 65-74 years (38.9 vs 0.8 cases per 100 person-years) and ≥ 75 years (61.9 vs 12.3 cases per 100 person-years).
- Older age (≥ 75 years) was associated with an increased risk for end-stage renal disease or death (aHR, 4.50; 95% CI, 1.83-11.09); however, frailty was not.
- The effect of frailty on end-stage renal disease or death varied by age, with a larger difference observed in individuals aged 65-74 years (frail vs nonfrail, 7.5 vs 2.0 cases per 100 person-years) than in those aged ≥ 75 years (13.5 vs 16.0 cases per 100 person-years).
IN PRACTICE:
“Our results highlight the fact that assessment of frailty in the care of older adults with ANCA-associated vasculitis can distinguish a group of patients at increased risk of severe infections who might benefit from interventions to minimize infection risk and optimize outcomes,” the authors wrote.
“Incorporating frailty screening into the management of ANCA-associated vasculitis provides an opportunity to offer personalized, evidence-based care to frail older adults,” Alexandra Legge, MD, Dalhousie University, Halifax, Nova Scotia, Canada, wrote in an associated comment published online in The Lancet Rheumatology.

LIMITATIONS:
The study’s observational design and single-center setting limited the generalizability of the findings. Residual confounding may have been possible despite adjustments for relevant baseline factors. The requirement of at least one healthcare encounter before baseline may have underrepresented individuals without frailty. Differences in treatment patterns after the baseline period were not controlled for.

The Biology of ‘Precancer’: Stopping Cancer Before It Starts
Some breast cancer types are more likely than others to recur. Researchers have known this for more than a decade.
But they have long wondered why.
“How did those tumor types arise?” said Christina Curtis, PhD, a professor of medicine, genetics and biomedical data science at Stanford University in California. “They’re all breast cancers. They’re all estrogen receptor positive. But these groups are different. When did they become different, and how is that determined?”
Dr. Curtis and colleagues are finally starting to answer these questions. They recently broke new ground in a study linking differences in cancer-related genes to disease subtype and aggressiveness.
DNA inherited from our parents is known as the germline genome. It affects whether the immune system attacks or retreats when confronted with variations that may lead to breast cancer.
“It turns out, the germline genome sculpts tumor evolution,” said Dr. Curtis.
The study is part of a growing effort to understand “precancer” — the critical period after cells have started to grow abnormally but before they’ve developed into cancer — a research trend that could trigger a decisive shift in how cancer treatments are realized. Therapeutics could be designed on the basis of the biology of these precancerous cells.
While biotech start-ups push new tests to catch cancer early, researchers like Dr. Curtis hope to stop cancer before it even starts.
“This is a really exciting area of research,” said Susan Domchek, MD, executive director of the Basser Center for BRCA at the University of Pennsylvania, Philadelphia, who was not involved in the study. “What we hope for is that, over time, we’re going to have more and more biologically driven interception.”
‘We’re Basically Unearthing the Dark Matter of the Human Genome’
Of course, we already have mechanical ways of heading off cancer, like having a precancerous polyp removed. But for the Stanford researchers, biologic interception is the goal. They hope to figure out how to use the immune system to stop the cancer.
In their study, they looked at DNA variabilities known as somatic aberrations or single-nucleotide protein sequences (SNPs). The HER2 gene, for example, can contain SNPs — possibly affecting how the HER2 protein regulates breast cell growth and division.
“There’s been a huge effort through genomewide association studies to link SNPs to cancer outcomes and risk,” Dr. Curtis said.
Focusing on people with a genetic predisposition for breast cancer, Dr. Curtis used machine learning to show that these variabilities can occur in specific epitopes (protein features that can trigger an immune response).
They also found that heightened variability can show up in a region of the genome called the human leukocyte antigen (HLA). Each HLA molecule can contain many epitopes.
“We developed a whole new algorithm to compute this ‘germline epitope burden,’ ” Dr. Curtis said. “We’re basically unearthing the dark matter of the human genome to ask about the interplay between SNPs and HLA class one presentation.”
These aberration-rich regions can grab the immune system’s attention. Sometimes the immune system identifies and eradicates those epitopes.
In that case: “I have immunosurveillance. I’ve cured my cancer,” said Nora Disis, PhD, director of the Cancer Vaccine Institute and a professor of medicine at the University of Washington, Seattle. Dr. Disis was not involved in the study.
But other times, the immune system finds a way around the high “epitope burden,” and the tumors become more aggressive and immunosuppressive. That’s when cancer forms.
This suggests a “critical juncture between preinvasive and invasive disease,” Dr. Curtis said.
And that “critical juncture” may very well be the optimal time for intervention.
The Precancer Push
Stanford’s findings add information to prior biomarkers and may provide a way to identify “bad-acting tumors” from a simple blood draw measuring germline epitope burden, Dr. Curtis said. Looking further ahead, “this also reveals a new source of epitopes that might be immunogenic and might be informative for the development of vaccines.”
Many labs are trying to understand the biology of precancer and exploring possible vaccines.
The National Cancer Institute’s Human Tumor Atlas Network is building three-dimensional models of the evolution from precancerous to advanced disease. And researchers at the Cancer Vaccine Institute at the University of Washington are developing a vaccine for a precancerous lesion linked to many ovarian cancers.
Dr. Domchek’s research explores whether breast cancers caused by mutations in the BRCA 1 and 2 genes can be intercepted at very early stages. In a clinical trial of healthy people with those mutations, Dr. Domchek and colleagues are attempting to “rev up the immune system to tackle telomerase,” an enzyme that’s over-expressed in 95% of cancers. The hope is for this experimental vaccine to lower their risk of developing cancer.
At the Fred Hutch Cancer Center, Seattle, Ming Yu, PhD, is studying how senescent cells affect immune cells in precancer. As cells age and stop dividing, she said, they can accumulate and create a “tumor-promoting microenvironment” in older people.
Dr. Yu has found that the antiaging drug rapamycin can eliminate those “zombie cells” in mice. She’s studying whether the “cleanup” can help prevent cancer and expects results in a few months.
In the years and decades to come, all of this could lead to a new era in cancer treatment.
“Most drug development starts with people with advanced cancer and then goes into the earlier and earlier spaces,” said Dr. Domchek. “But it may be that we’re thinking about it all wrong and that you really have to understand the unique biology of early lesions to go after them.”

Are Targeted Drugs the Future in Colorectal Cancer?
This transcript has been edited for clarity.
Welcome back, everybody, from the European Society for Medical Oncology (ESMO) Congress in the wonderful city of Barcelona in Spain. I was coming from ESMO drenched in huge amounts of new data.
They looked at molecularly targeted drugs, some early-stage and a later-stage study in which there’s some evidence of promise.
She talked a little about the preliminary results from three trials suggesting some benefits, pretty marginal, of cetuximab plus irinotecan in patients who’d already had epidermal growth factor receptor (EGFR) receptor inhibitory treatment.
Amivantamab plus FOLFOX or FOLFIRI was also discussed. This is a bispecific antibody against EGFR and MET. Again, very early, but there are some potential marginal benefits coming through. She also discussed the results of a larger phase 3 randomized trial with an old friend, ramucirumab, the anti-angiogenic agent, in which the ramucirumab in combination with trifluridine-tipiracil failed to meet its primary endpoint of improving overall survival.
There were some interesting post hoc subgroup analyses showing potential benefits for women, left-sided tumors, and so on. She made an excellent presentation, which she summarized by saying that the future of colorectal cancer treatment lies in further defining molecularly targeted treatment.
Nobody would disagree with that. What is interesting, though, is that, if I were to use the analogy of mining, the more deeply we mine, perhaps the lower marginal the benefits are becoming. There’s no doubt that we’re understanding better the exquisite machinery of cell signaling. We understand that there’s redundancy, there’s repeatability, and the possibility of emergence of resistance can come quite quickly.
Although we can develop ever more precise molecularly targeted drugs, it does seem as if the clinical benefits of these, in some cases, are marginally small. I’d like to suggest that, in addition to Sara’s call for more molecularly targeted drugs, we should think about cellular targets.
We did a large amount of work (as have many others, of course) looking at the immune tumor microenvironment and trying to, in a way, separate and understand the contribution of the individual component cells — of which there are many, including cancer-associated fibroblasts, natural killer (NK) cells, whole hosts of different types of T-cell subsets, B cells, tumor-associated neutrophils, and so on — and how these interact together and of interact with the epithelial colorectal cancer cells.
We are collaborating with Patrick Soon-Shiong, a clever chap, who believes in combination immunotherapy, dissecting and understanding the individual role of these different cells, and coming up with cellular therapies or targeted therapies that either inhibit or stimulate some of the different cell components to be the way ahead for an immunologically cold tumor such as microsatellite-stable colorectal cancer.
For example, we’re looking at combinations of our histone deacetylase (HDAC) inhibitor, which switches on the machinery of antigen presentation, up-regulating major histocompatibility complex (MHC) class 1 and class 2, and some other of the molecules involved in antigen chopping and presentation; it’s like turning a microsatellite-stable immunologically cold tumor hot; an interleukin-15 superagonist that stimulates NK cells; and we’ve found a way to manipulate and reduce the number of Treg cells.
We have various approaches to reducing the microenvironment transforming growth factor beta and some of the downstream elements from that. We can look at combinatorial immunotherapy, but thinking at a cellular level and developing anticancer agents that either activate or inhibit these different cell components. I’d bring the two together.
Of course, the future has got to be better molecularly targeted drugs, but let’s think at a macro level as to how we can look at the different cellular interactions within the tumor microenvironment, and perhaps through that, come up with synergistic immunotherapeutic combinations.
Dr. Kerr is Professor, Nuffield Department of Clinical Laboratory Science, University of Oxford, and Professor of Cancer Medicine, Oxford Cancer Centre, both in England. He reported conflicts of interest with Celleron Therapeutics, Oxford Cancer Biomarkers, Afrox, GlaxoSmithKline, Genomic Health, and Merck Serono.

We did a large amount of work (as have many others, of course) looking at the immune tumor microenvironment and trying to, in a way, separate and understand the contribution of the individual component cells — of which there are many, including cancer-associated fibroblasts, natural killer (NK) cells, whole hosts of different types of T-cell subsets, B cells, tumor-associated neutrophils, and so on — and how these interact together and of interact with the epithelial colorectal cancer cells.
We are collaborating with Patrick Soon-Shiong, a clever chap, who believes in combination immunotherapy, dissecting and understanding the individual role of these different cells, and coming up with cellular therapies or targeted therapies that either inhibit or stimulate some of the different cell components to be the way ahead for an immunologically cold tumor such as microsatellite-stable colorectal cancer.
For example, we’re looking at combinations of our histone deacetylase (HDAC) inhibitor, which switches on the machinery of antigen presentation, up-regulating major histocompatibility complex (MHC) class 1 and class 2, and some other of the molecules involved in antigen chopping and presentation; it’s like turning a microsatellite-stable immunologically cold tumor hot; an interleukin-15 superagonist that stimulates NK cells; and we’ve found a way to manipulate and reduce the number of Treg cells.
We have various approaches to reducing the microenvironment transforming growth factor beta and some of the downstream elements from that. We can look at combinatorial immunotherapy, but thinking at a cellular level and developing anticancer agents that either activate or inhibit these different cell components. I’d bring the two together.
Of course, the future has got to be better molecularly targeted drugs, but let’s think at a macro level as to how we can look at the different cellular interactions within the tumor microenvironment, and perhaps through that, come up with synergistic immunotherapeutic combinations.

Welcome back, everybody, from the European Society for Medical Oncology (ESMO) Congress in the wonderful city of Barcelona in Spain. I was coming from ESMO drenched in huge amounts of new data.
They looked at molecularly targeted drugs, some early-stage and a later-stage study in which there’s some evidence of promise.
She talked a little about the preliminary results from three trials suggesting some benefits, pretty marginal, of cetuximab plus irinotecan in patients who’d already had epidermal growth factor receptor (EGFR) receptor inhibitory treatment.
Amivantamab plus FOLFOX or FOLFIRI was also discussed. This is a bispecific antibody against EGFR and MET. Again, very early, but there are some potential marginal benefits coming through. She also discussed the results of a larger phase 3 randomized trial with an old friend, ramucirumab, the anti-angiogenic agent, in which the ramucirumab in combination with trifluridine-tipiracil failed to meet its primary endpoint of improving overall survival.
There were some interesting post hoc subgroup analyses showing potential benefits for women, left-sided tumors, and so on. She made an excellent presentation, which she summarized by saying that the future of colorectal cancer treatment lies in further defining molecularly targeted treatment.
Nobody would disagree with that. What is interesting, though, is that, if I were to use the analogy of mining, the more deeply we mine, perhaps the lower marginal the benefits are becoming. There’s no doubt that we’re understanding better the exquisite machinery of cell signaling. We understand that there’s redundancy, there’s repeatability, and the possibility of emergence of resistance can come quite quickly.
Although we can develop ever more precise molecularly targeted drugs, it does seem as if the clinical benefits of these, in some cases, are marginally small. I’d like to suggest that, in addition to Sara’s call for more molecularly targeted drugs, we should think about cellular targets.

Adding Short-term ADT to High-Dose Radiotherapy Benefits Some Prostate Cancers
according to results of the phase 3 GETUG 14 trial.
The 5-year disease-free survival rate was 84% in patients who received short-term ADT plus radiotherapy, compared with 76% in those who received radiotherapy alone.
In addition, short-term ADT with high-dose radiotherapy didn’t increase genitourinary or gastrointestinal toxicities, said Nicolas Demogeot, MD, with the Cancer Institute of Lorraine, Vandœuvre-lès-Nancy, France, who presented the results at the annual meeting of the American Society for Radiation Oncology (ASTRO).
Adding short-term ADT to standard-dose radiotherapy has been shown to improve all clinical outcomes, Dr. Demogeot noted, but few trials have tested it with high-dose radiotherapy. GETUG 14 was designed to do just that.
The multicenter, randomized, phase 3 trial enrolled 376 patients with intermediate- or high-risk localized prostate cancer who had PSA levels under 30 ng/mL and no clinical involvement of the seminal vesicles.
Patients were randomly allocated to high-dose radiotherapy (80 Gy) alone or high-dose radiotherapy plus monthly triptorelin and daily flutamide for a total duration of 4 months, starting 2 months prior to radiotherapy.
Disease-free survival was the primary endpoint. Secondary endpoints were overall survival, biochemical failure, metastasis failure, toxicity, and quality of life.
The modified intention-to-treat cohort included 191 patients in the radiotherapy-only group and 179 in the short-term ADT plus radiotherapy group. The two groups were well balanced. In both, patients ranged in age from 64 to 73 years; about two thirds had intermediate-risk disease; 70% received three-dimensional conformal radiotherapy, and 30% received intensity-modulated radiotherapy.
Overall, adding short-term ADT to high-dose radiotherapy was associated with a 36% relative improvement in 5-year disease-free survival (84% vs 76% with radiotherapy alone, hazard ratio [HR], 0.64; P = .02).
In subgroup analyses, intermediate-risk patients who received short-term ADT with high-dose radiotherapy demonstrated a significant improvement in disease-free survival (87% vs 74% with radiotherapy alone; HR, 0.55; P = .02). However, there was no significant disease-free survival benefit with short-term ADT with high-dose radiotherapy in high-risk patients (79% vs 75%; HR, 0.76; P = .40).
On multivariable analysis, short-term ADT with high-dose radiotherapy was associated with significant disease-free survival benefits (HR, 0.66; P = .038).
Patients who received short-term ADT with high-dose radiotherapy were significantly less likely to experience biochemical failure (10% vs 21%; HR, 0.45; P = .001), but there was no significant difference in metastasis failure (HR, 0.5; P = .09) or overall survival (HR, 1.22; P = .54).
As for adverse events, the two groups did not demonstrate significant differences in the proportions of early or late grade 2 or higher gastrointestinal or genitourinary toxicities.
Patients in the short-term ADT with high-dose radiotherapy group did experience a greater frequency of early grade 2 or higher erectile dysfunction (31% vs 6%; P < .001), but not late grade 2 or higher erectile dysfunction (63% vs 61%; P = .89).
Limitations of the study include a low power to detect differences between intermediate- and high-risk patients and the short follow-up period.
The GETUG 14 trial “confirms that short-term ADT improves disease-free survival when combined with dose-escalated radiation therapy for intermediate-risk prostate cancer,” Mark A. Hallman, MD, PhD, with Fox Chase Cancer Center, Philadelphia, Pennsylvania, who was not involved in the study, said in an interview. “However, there was not a similar benefit among the smaller subpopulation with high-risk disease.”
Outside expert Amar Kishan, MD, radiation oncologist, UCLA Jonsson Comprehensive Cancer Center, agreed, adding that “it is also reassuring to see no increase in genitourinary or gastrointestinal toxicity and no longer-term impact on erectile dysfunction.”
The GETUG-14 trial was supported by the French Ministry of Health and Ipsen. Dr. Demogeot has disclosed relationships with Ipsen, Janssen, Accord Healthcare, Astellas, and Bayer. Dr. Hallman had no relevant disclosures. Dr. Kishan has disclosed relationships with Boston Scientific, Janssen, Varian Medical Systems, ViewRay, and POINT Biopharma.

FDA Antidepressant Warnings Tied to Increase in Suicidality
, a new analysis suggests.
Investigators said the totality of evidence supports “reevaluation and possible replacement” of the US Food and Drug Administration (FDA) black box warning with routine warnings in product labeling.
“The sudden, simultaneous, and sweeping effects of these warnings — the reduction in depression treatment and increase in suicide — are documented across 14 years of strong research. The consistency in observed harms and absence of observed benefits after the black box warnings indicate this is not a coincidence,” lead author Stephen Soumerai, ScD, professor of population medicine, Harvard Medical School at Harvard Pilgrim Health Care Institute, Boston, said in a news release.
The study was published online in Health Affairs.
How Did We Get Here?
In October 2003, the FDA warned that antidepressants may be associated with suicidality among people younger than age 18 years soon after starting treatment. In January 2005, the FDA required a permanent black box warning of this risk on product labels and in television and print advertising for all antidepressant drugs.
In May 2007, the FDA expanded the 2005 black box warning to include young adults through age 24, and this broader warning remains in effect today.
Dr. Soumerai and colleagues evaluated the intended and unintended outcomes of the youth antidepressant warnings through a systematic review of “the most credible evidence in the field,” Dr. Soumerai said.
Through an exhaustive literature search, the researchers identified 34 studies of depression and suicide-related outcomes published in peer-reviewed journals after the warnings were issued.
Eleven of these studies measured abrupt changes in outcome trends following the warnings and were included in their analyses. These outcomes included monitoring for suicidality, physician visits for depression, depression diagnoses, psychotherapy visits, antidepressant treatment and use and psychotropic drug poisonings (a proxy for suicide attempts), and suicide deaths.
More Harms Than Benefits
Four studies, with more than 12 million patients, found “consistent evidence of sudden and substantial” long-term declines in doctor visits for depression and depression diagnoses after the FDA warnings, the study team noted.
These studies showed increases in physician visits for depression and depression diagnoses in the years before the warnings and abrupt, sustained declines, ranging from 20% to 45%, in visits and diagnoses after the warnings. “Some spillover occurred in comparison groups of adults, who were not targeted by the FDA warnings,” the study team said.
Seven studies revealed evidence that the FDA warnings were followed by abrupt reductions in antidepressant treatment and use, ranging from 20% to 50%. Most of these studies showed increasing use of antidepressants in the years before the FDA warnings, followed by abrupt and sustained reductions in use afterward.
Three studies found evidence of declining or flat trends in psychotropic drug poisonings and suicide deaths among pediatric patients before the warnings, followed by abrupt increases in these trends after the warnings were issued.
The intent of the warnings was to increase physician monitoring of suicidality of patients treated with antidepressants, but the data suggest that this did not occur.
Less than 5% of pediatric patients were monitored in accordance with FDA’s recommended contact schedule recommendations after the warnings were issued. This low rate was unchanged from the rate before the warnings.
No study documented improvements in mental health care or declines in suicide attempts or suicides after the warnings went into effect.
“The overwhelming evidence suggests that the ongoing use of these warnings may result in more harms than benefits,” the authors wrote.
Concerning Data
The results are “very concerning and provide reason to pause, rethink, and possibly recalibrate boxed warning recommendations as it relates to antidepressants in younger populations,” said Roger McIntyre, MD, professor of psychiatry and pharmacology, University of Toronto, Canada, and head of the Mood Disorders Psychopharmacology Unit.
Dr. McIntyre, who wasn’t involved in the study, said the data “unfortunately” provide evidence suggesting that the boxed warning had the “unintended consequence of increasing the likelihood that persons would not receive adequate healthcare for their mental disorder, consequently resulting in unfavorable outcomes, including suicidality.”
He added, “Two decades have now passed with additional information available, which not only appears to recalibrate the initial risk assessment but provides an opportunity for us to reduce the externality of decreasing access to healthcare for people living with mental illness during their youth years.”
A spokesperson for the FDA said that “generally, the FDA does not comment on specific studies, but evaluates them as part of the body of evidence to further our understanding about a particular issue and assist in our mission to protect public health.”
The study had no commercial funding. Disclosures for the authors are listed with the original article. Dr. McIntyre has received speaker/consultation fees from Lundbeck, Janssen, Alkermes, Neumora Therapeutics, Boehringer Ingelheim, Sage, Biogen, Mitsubishi Tanabe, Purdue, Pfizer, Otsuka, Takeda, and Neurocrine.

Mycosis Fungoides: Measured Approach Key to Treatment
HUNTINGTON BEACH, CALIFORNIA — When patients of Aaron Mangold, MD, first learn they have mycosis fungoides (MF), the most common form of primary cutaneous T-cell lymphoma (CTCL), some are concerned about whether the diagnosis means a shortened life expectancy.
Dr. Mangold, codirector of the multidisciplinary cutaneous lymphoma clinic at Mayo Clinic, Scottsdale, Arizona, said at the annual meeting of the Pacific Dermatologic Association. “For early-stage disease, I think of it more like diabetes; this is really a chronic disease” that unlikely will be fatal but may be associated with increased morbidity as the disease progresses, and “the overall goal of therapy should be disease control to increase quality of life.”
Patient- and lymphoma-specific factors drive the choice of therapy. The focus for patients with early-stage disease, Dr. Mangold said, is to treat comorbidities and symptoms, such as itch or skin pain, maximize their quality of life, and consider the potential for associated toxicities of therapy as the disease progresses. Start with the least toxic, targeted, nonimmunosuppressive therapy, “then work toward more toxic immunosuppressive therapies,” he advised. “Use toxic agents just long enough to control the disease, then transition to a maintenance regimen with less toxic immunosuppressive agents.”
When Close Follow-Up Is Advised
According to unpublished data from PROCLIPI (the Prospective Cutaneous Lymphoma International Prognostic Index) study presented at the fifth World Congress of Cutaneous Lymphomas earlier in 2024, the following factors warrant consideration for close follow-up and more aggressive treatment: Nodal enlargement greater than 15 mm, age over 60 years, presence of plaques, and large-cell transformation in skin. “These are some of the stigmata in early disease that might guide you toward referring” a patient to a CTCL expert, Dr. Mangold said. (Consensus-based recommendations on the management of MF in children were published in August of 2024.)
According to Dr. Mangold, topical/skin-directed therapies are best for early-stage disease or in combination with systemic therapies in advanced disease. For early-stage disease, one of his preferred options is daily application of a skin moisturizer plus a topical corticosteroid such as clobetasol, halobetasol, or augmented betamethasone, then evaluating the response at 3 months. “This is a cheap option, and we see response rates as high as 90%,” he said. “I don’t often see steroid atrophy when treating patients with active MF. There’s a tendency to think, ‘I don’t want to overtreat.’ I think you can be aggressive. If you look in the literature, people typically pulse twice daily for a couple of weeks with a 1-week break.”
Mechlorethamine, a topical alkylating gel approved in 2013 for the treatment of early-stage MF, is an option when patients fail to respond to topical steroids, prefer to avoid steroids, or have thick, plaque-like disease. With mechlorethamine, it is important to “start slow and be patient,” Dr. Mangold said. “Real-world data shows that it takes 12-18 months to get a good response. Counsel patients that they are likely to get a rash, and that the risk of rash is dose dependent.”
Other treatment options to consider include imiquimod, which can be used for single refractory spots. He typically recommends application 5 days per week with titration up to daily if tolerated for up to 3 months. “Treat until you get a brisk immune response,” he said. “We’ve seen patients with durable, long-term responses.”
UVB Phototherapy Effective
For patients with stage IB disease, topical therapies are less practical and may be focused on refractory areas of disease. Narrow-band UVB phototherapy is the most practical and cost-effective treatment, Dr. Mangold said. Earlier-stage patch disease responds to phototherapy in up to 80% of cases, while plaque-stage disease responds in up to half of cases. “More frequent use of phototherapy may decrease time to clearance, but overall response is similar.”
Dr. Mangold recommends phototherapy 2-3 days per week, titrating up to a maximal response dose, and maintaining that dose for about 3 months. Maintenance involves tapering the phototherapy dose to a minimal dose with continued response. “The goal is to prevent relapse,” he said.
For patients with MF of stage IIB and higher, he considers total skin electron beam therapy, an oral retinoid with phototherapy, systemic agents, and focal radiation with systemic treatment. One of his go-to systemic options is bexarotene, which he uses for early-stage disease refractory to treatment or for less aggressive advanced disease. “We typically use a low dose ... and about half of patients respond,” Dr. Mangold said. The time to response is about 6 months. Bexarotene causes elevated lipids and low thyroid function, so he initiates patients on fenofibrate and levothyroxine at baseline.
Another systemic option is brentuximab vedotin, a monoclonal antibody that targets cells with CD30 expression, which is typically administered in a specialty center every 3 weeks for up to 16 cycles. “In practice, we often use six to eight cycles to avoid neuropathy,” he said. “It’s a good debulking agent, the time to response is 6-9 weeks, and it has a sustained response of 60%.” Neuropathy can occur with treatment, but improves over time.
Other systemic options for MF include romidepsin, mogamulizumab, and extracorporeal photopheresis used in erythrodermic disease.
Radiation An Option in Some Cases
Dr. Mangold noted that low doses of radiation therapy can effectively treat MF lesions in as little as one dose. “We can use it as a cure for a single spot or to temporarily treat the disease while other therapies are being started,” he said. Long-term side effects need to be considered when using radiation. “The more radiation, the more side effects.”
Dr. Mangold disclosed that he is an investigator for Sun Pharmaceutical, Solagenix, Elorac, miRagen, Kyowa Kirin, the National Clinical Trials Network, and CRISPR Therapeutics. He has also received consulting fees/honoraria from Kirin and Solagenix.

Facial Angioedema, Rash, and “Mastitis” in a 31-Year-Old Female
A previously healthy 31-year-old female active-duty Navy sailor working as a calibration technician developed a painful, erythematous, pruritic, indurated plaque on her left breast. The sailor was not lactating and had no known family history of malignancy. Initially, she was treated by her primary care practitioner for presumed mastitis with oral cephalexin and then with oral clindamycin with no symptom improvement. About 2 weeks after the completion of both antibiotic courses, she developed angioedema and periorbital edema (Figure 1), requiring highdose corticosteroids and antihistamines with a corticosteroid course of prednisone 40 mg daily tapered to 10 mg daily over 12 days and diphenhydramine 25 mg to use up to 4 times daily. Workup for both was acquired and hereditary angioedema was unremarkable. Two months later, the patient developed patches of alopecia, oral ulcerations, and hypopigmented plaques with a peripheral hyperpigmented rim on the central face and bilateral conchal bowls (Figure 2). She also developed hypopigmented papules with peripheral hyperpigmentation on the bilateral dorsal hands overlying the metacarpal and proximal interphalangeal joints, which eventually ulcerated (Figure 3). Laboratory evaluation, including tests for creatine kinase, aldolase, transaminases, lactate dehydrogenase, and autoantibodies (antiJo-1, anti-Mi-2, anti-MDA-5, anti-TIF-1, anti-NXP-2, and anti-SAEP), were unremarkable. A punch biopsy from a papule on the right dorsal hand showed superficial perivascular lymphohistiocytic inflammation with a subtle focal increase in dermal mucin, highlighted by the colloidal iron stain. Further evaluation of the left breast plaque revealed ER/PR+ HER2- stage IIIB inflammatory breast cancer.
DISCUSSION
Based on the clinical presentation and diagnosis of inflammatory breast cancer, the patient was diagnosed with paraneoplastic clinically amyopathic dermatomyositis (CADM). She was treated for her breast cancer with an initial chemotherapy regimen consisting of dose-dense cyclophosphamide and doxorubicin followed by paclitaxel. The patient underwent a mastectomy, axillary lymph node dissection, and 25 sessions of radiation therapy, and is currently continuing therapy with anastrozole 1 mg daily and ovarian suppression with leuprorelin 11.25 mg every 3 months. For the severe angioedema and dermatomyositis-like cutaneous findings, the patient was continued on high-dose corticosteroids at prednisone 60 mg daily with a prolonged taper to prednisone 10 mg daily. After about 10 months, she transitioned from prednisone 10 mg daily to hydrocortisone 30 mg daily and is currently tapering her hydrocortisone dosing. She was additionally started on monthly intravenous immunoglobulin, hydroxychloroquine 300 mg daily, and amlodipine 5 mg daily. The ulcerated papules on her hands were treated with topical clobetasol 0.05% ointment applied daily, topical tacrolimus 0.1% ointment applied daily, and multiple intralesional triamcinolone 5 mg/mL injections. With this regimen, the patient experienced significant improvement in her cutaneous symptoms.
CADM is a rare autoimmune inflammatory disease featuring classic dermatomyositis-like cutaneous findings such as a heliotrope rash and Gottron papules. Ulcerative Gottron papules are less common than the typical erythematous papules and are associated more strongly with amyopathic disease.1 Paraneoplastic myositis poses a diagnostic challenge because it presents like an idiopathic dermatomyositis and often has a heterogeneous clinical presentation with additional manifestations, including periorbital edema, myalgias, dysphagia, and shortness of breath. If clinically suspected, laboratory tests (eg, creatine kinase, aldolase, transaminases, and lactate dehydrogenase) can assist in diagnosing paraneoplastic myositis. Additionally, serologic testing for autoantibodies such as anti-CADM-140, anti-Jo-1, anti-Mi-2, antiMDA-5, anti-TIF-1, anti-NXP-2, and antiSAE can assist the diagnosis and predict disease phenotype.1,2
Malignancy can precede, occur during, or develop after the diagnosis of CADM.3 Malignancies most often associated with CADM include ovarian, breast, and lung cancers.4 Despite the strong correlation with malignancy, there are currently no screening guidelines for malignancy upon inflammatory myositis diagnosis. Therefore, it is important to consider the entirety of a patient’s clinical presentation in establishing further evaluation in the initial diagnostic workup.
There are numerous systemic complications associated with inflammatory myositis and imaging modalities can help to rule out some of these conditions. CADM is strongly associated with the development of interstitial lung disease, so chest radiography and pulmonary function testing are often checked.1 Though cardiac and esophageal involvement are more commonly associated with classic dermatomyositis, it may be useful to obtain an electrocardiogram to rule out conduction abnormalities from myocardial involvement, along with esophageal manometry to evaluate for esophageal dysmotility.1,5
In the management of paraneoplastic CADM, the underlying malignancy should be treated first.6 If symptoms persist after the cancer is in remission, then CADM is treated with immunosuppressive medications such as methotrexate, mycophenolate mofetil, or azathioprine. Physical therapy can also provide further symptom relief for those suffering from proximal weakness.
CONCLUSIONS
Presumed mastitis, angioedema, and eczematous lesions for this patient were dermatologic manifestations of an underlying inflammatory breast cancer. This case highlights the importance of early recognition, the diagnosis of CADM and awareness of its association with underlying malignancy, especially within the primary care setting where most skin concerns are addressed. Early clinical suspicion and a swift diagnostic workup can further optimize multidisciplinary management, which is often required to treat malignancies.

Ulcerative Gottron papules are less common than the typical erythematous papules and are associated more strongly with amyopathic disease.1 Paraneoplastic myositis poses a diagnostic challenge because it presents like an idiopathic dermatomyositis and often has a heterogeneous clinical presentation with additional manifestations, including periorbital edema, myalgias, dysphagia, and shortness of breath. If clinically suspected, laboratory tests (eg, creatine kinase, aldolase, transaminases, and lactate dehydrogenase) can assist in diagnosing paraneoplastic myositis. Additionally, serologic testing for autoantibodies such as anti-CADM-140, anti-Jo-1, anti-Mi-2, antiMDA-5, anti-TIF-1, anti-NXP-2, and antiSAE can assist the diagnosis and predict disease phenotype.1,2
Malignancy can precede, occur during, or develop after the diagnosis of CADM.3 Malignancies most often associated with CADM include ovarian, breast, and lung cancers.4 Despite the strong correlation with malignancy, there are currently no screening guidelines for malignancy upon inflammatory myositis diagnosis. Therefore, it is important to consider the entirety of a patient’s clinical presentation in establishing further evaluation in the initial diagnostic workup.
There are numerous systemic complications associated with inflammatory myositis and imaging modalities can help to rule out some of these conditions. CADM is strongly associated with the development of interstitial lung disease, so chest radiography and pulmonary function testing are often checked.1 Though cardiac and esophageal involvement are more commonly associated with classic dermatomyositis, it may be useful to obtain an electrocardiogram to rule out conduction abnormalities from myocardial involvement, along with esophageal manometry to evaluate for esophageal dysmotility.1,5
In the management of paraneoplastic CADM, the underlying malignancy should be treated first.6 If symptoms persist after the cancer is in remission, then CADM is treated with immunosuppressive medications such as methotrexate, mycophenolate mofetil, or azathioprine. Physical therapy can also provide further symptom relief for those suffering from proximal weakness.
CONCLUSIONS
Presumed mastitis, angioedema, and eczematous lesions for this patient were dermatologic manifestations of an underlying inflammatory breast cancer. This case highlights the importance of early recognition, the diagnosis of CADM and awareness of its association with underlying malignancy, especially within the primary care setting where most skin concerns are addressed. Early clinical suspicion and a swift diagnostic workup can further optimize multidisciplinary management, which is often required to treat malignancies.

Ghost Fat: The Unseen Consequences of Weight Loss
Many people who lose weight, whether through diet and lifestyle changes, medication, or bariatric surgery, recognize their body has changed. While they also experience improvements in quality of life and psychosocial areas, that’s not true for everyone. Some patients don’t “see” they’ve lost weight — a phenomenon referred to as “phantom fat,” “ghost fat,” or “vestigial body image.”
“Most people are happy with their appearance, or at least their body shape, after weight loss — although some are unhappy with the loose, sagging skin that can follow weight loss and seek plastic surgery to remedy that,” David B. Sarwer, PhD, director of the Center for Obesity Research and Education and professor of social and behavioral sciences, Temple University College of Public Health, Philadelphia, told this news organization. “There’s a subset of people who remain dissatisfied with their body image, including their shape.”
This body dissatisfaction of people who lose weight may be long-standing, predating the weight loss, or may be new because weight loss has catalyzed a host of previously unaddressed psychosocial issues. Some may show up at assessments on treatment onset, while others may be detected by monitoring changes during or after weight loss. “Mental health counseling after bariatric surgery is greatly underutilized,” Dr. Sarwer observed.
Ghost Fat
Research has corroborated the lingering self-perception of being “obese” vs “ex-obese.” In one study, patients who had undergone bariatric surgery reported being unable to see the difference in their size and shape 18-30 months following their procedure, despite substantial weight loss.
Some research suggests that rapid weight loss (eg, through bariatric surgery) is more likely to generate the perception of “phantom fat,” but additional research is needed to investigate whether the mode and speed of weight loss affect subsequent body image.
Being habituated to one’s former appearance may play a role, Dr. Sarwer suggested. “We see this not only with weight loss but with other body-altering procedures. It takes the brain time to catch up to the new appearance. In rhinoplasty, for example, it may take patients a while before they become accustomed to looking at their new face in the mirror after decades of looking at a more prominent nose.”
Years of Social Stigma
It may also take time for people to overcome years of enduring the stigma of obesity.
There are “pervasive” negative attitudes implying that individuals who are overweight and/or obese are “lazy, weak-willed, lacking in self-discipline and willpower” — a problem compounded by social media and media in general, which present unrealistic, glorified body images and disparaging messages about those with weight problems.
“Body image is a construct, rather than what you see in the mirror,” Sheethal Reddy, PhD, a psychologist at the Emory Bariatric Center, Emory University Hospital Midtown, Atlanta, told this news organization. “It’s the mental construct of our physical selves.”
According to Dr. Reddy, body image develops “within a broader societal context and is influenced by the person’s ethnic, racial, and cultural heritage.”
Adolescents are particularly vulnerable to body dissatisfaction. This is compounded in those with obesity, who often experience weight-based victimization and internalized weight-based stigma, compared with adolescents with lower weights. Weight stigma often takes the form of teasing and bullying.
“Appearance-related bullying and teasing during childhood and adolescence can reverberate into adulthood and persist throughout the lifespan,” Dr. Sarwer said. “When we see these patients and ask if they’ve ever been teased or bullied, not only do many say yes but it takes them back to those moments, to that origin story, and they remember someone saying something mean, cruel, and hurtful.”
Stigmatizing experiences can affect subjective body image, even after the weight has been lost and the person’s body is objectively thinner. Research comparing individuals who were overweight and lost weight to individuals who are currently overweight and haven’t lost weight and individuals who were never overweight suggests that “vestigial” body disparagement may persist following weight loss — especially in those with early-onset obesity.
The Role of Genetics
Genetics may contribute to people’s self-perception and body dissatisfaction, both before and after weight loss. A study of 827 community-based adolescents examined the association between polygenic risk scores (PRS) for body mass index (BMI) and type 2 diabetes and symptoms of body dissatisfaction and depression.
“Given the significant genetic role in BMI, we wanted to explore whether genetic risk for BMI might also predict body dissatisfaction,” lead author Krista Ekberg, MS, a doctoral candidate in clinical psychology, Rosalind Franklin University of Medicine and Science, North Chicago, Illinois, told this news organization.
Genetic influences on BMI, as measured by PRS, were significantly associated with both phenotypic BMI and body dissatisfaction. “The association between PRS and body dissatisfaction was largely explained by BMI, suggesting that BMI itself accounts for much of the link between genetic risk and body dissatisfaction.”
Psychiatric History and Trauma
Adverse experiences, particularly sexual or physical abuse, may also account for body dissatisfaction after weight loss. “When some people with a history of this type of abuse lose a large amount of weight — typically after bariatric surgery — they often go through a period of emotional turbulence,” Dr. Sarwer said.
Childhood maltreatment can also be associated with body image disturbances in adulthood, according to a meta-analysis of 12 studies, encompassing 15,481 participants. Sexual abuse is “surprisingly common” among patients with obesity, according to Dr. Sarwer. A chart review of 131 patients revealed that 60% of those who reported a history of rape or sexual molestation were ≥ 50 pounds overweight vs only 28% of age- and sex-matched controls without a history of abuse. Other studies have corroborated these findings.
Excess weight can serve an “adaptive function,” Dr. Sarwer noted. It can be a self-protective mechanism that “insulates” them from sexual advances by potential romantic partners or abusers. Some may find that, after weight loss, repressed memories of a sexual assault surface as a result of the newer, more “attractive” appearance. Feeling vulnerable in their thinner bodies, they may need to regard themselves as overweight to maintain that feeling of “protection.” Weight loss may also trigger memories, flashbacks, or nightmares, as people return to a weight at which they were abused.
Dissociation is another mechanism linking trauma with post–weight loss body dysmorphia, Supatra Tovar, PsyD, RD, a clinical psychologist and registered dietitian with a practice in California, told this news organization. Dissociation from the body is often a coping mechanism for dealing with an overwhelming traumatic experience.
Individuals with a history of depression, anxiety, or posttraumatic stress disorder have higher levels of body dysmorphia, both before and after weight loss. One study found that patients undergoing bariatric surgery who had some type of psychopathology and other psychological risk factors were significantly more likely to report body image concerns 3 months after the surgery. Body image concerns were also more common in patients with preoperative depression, current psychotropic medication use, and a history of outpatient therapy or psychotropic medication use.
“Depression, anxiety, and trauma play a role in how you see yourself and how you carry yourself,” Dr. Reddy said. “This is wrapped up in any type of psychopathology. Being depressed is like looking at yourself through a cloud. It’s the opposite of ‘rose-colored glasses’ and instead, looking at yourself through a negative lens.”
Diagnosis and Interventions
Some helpful tools to assess the presence and extent of weight dissatisfaction and body dysmorphia include the Eating Disorder Inventory — Body Dissatisfaction Subscale and the Body Shape Questionnaire. It’s also important to take into account “the extent to which people are invested in their appearance psychologically,” Dr. Sarwer advised. The AO subscale of the Multidimensional Body-Self Relations Questionnaire generally assesses this. The Body Image Quality of Life Inventory assesses how and to what extent the perceived body image affects the person’s quality of life.
Experts recommend cognitive behavioral therapy (CBT) as an evidence-based intervention for body image issues, including those following weight loss.
“There’s an extensive CBT body image therapy program specifically tailored to the needs of overweight and obese individuals,” Dr. Sarwer said. “We don’t ignore historical variables that may have contributed to the problem, like early bullying, but we encourage people to think about what’s going on in their day-to-day life today. We drill down not only into the maladaptive behaviors but also the cognition and beliefs that may be erroneous but underlie these behaviors.”
The aim of CBT is to “modify irrational and dysfunctional thoughts, emotions, and behaviors through techniques such as self-monitoring, cognitive structuring, psychoeducation, desensitization, and exposure and response prevention.” The program laid out in Cash’s body image workbook includes eight steps. (Figure).
Weight Loss Doesn’t Automatically Equate With Happiness
Another realistic expectation runs counter to a common misperception that becoming thin will automatically translate into becoming happier. That’s not always the case, according to Dr. Tovar.
“If you haven’t worked deeply on addressing self-compassion and understanding that who you are at the core has nothing to do with your physical appearance, you can have an empty feeling once you’ve reached this point,” she said. “You still don’t know who you are and what you’re contributing to the world [because] you’ve been so focused on losing weight.”
Weight loss can also “unmask” questions about self-worth, even when receiving compliments about one’s “improved” appearance. “Praise and compliments after weight loss can be a double-edged sword,” Dr. Tovar observed. “You might think, ‘I wasn’t accepted or praised when I was overweight. The only way to be acceptable or validated is by losing weight, so I have to continue losing weight.’ ” This fuels fear of regaining the weight and can lead to continuing to see oneself as overweight, perhaps as a way to stay motivated to continue with weight loss. “Feeling that one’s value depends on remaining thin hampers body satisfaction,” she said.
Dr. Tovar, author of the book Deprogram Diet Culture: Rethink Your Relationship with Food, Heal Your Mind, and Live a Diet-Free Life, encourages people to shift the emphasis from weight loss to a holistic focus on self-worth and to explore obstacles to those feelings both before and after weight loss.
Endocrinologists and other medical professionals can help by not engaging in “weight and body shaming,” Dr. Tovar said.
She recommends physicians “encourage patients to tune in to their own bodies, helping them become more aware of how different foods affect their physical and emotional well-being.”
Set realistic expectations through “open, nonjudgmental conversations about the complexities of metabolism, weight, and health.”
Dr. Tovar advises rather than focusing on weight loss as the primary goal, physicians should focus on health markers such as blood glucose, energy levels, mental well-being, and physical fitness.
Prioritize “listening over lecturing.” Begin with empathy, asking questions such as “How do you feel about your health right now? What changes have you noticed in your body lately?” Doing this “creates space for the patient to express their concerns without feeling judged or shamed.”
Refer patients to a mental health professional when a patient exhibits signs of disordered eating or poor body image or when emotional factors are playing a significant role in the relationship with food and weight. “If a patient is caught in a cycle of dieting and weight gain, struggles with binge eating, or displays symptoms of depression or anxiety related to body, then psychological help is crucial.”
Ultimately, the goal of treatment “should be to provide a safe, supportive environment where patients can heal — not just physically but also emotionally and mentally,” Dr. Tovar added.
Dr. Tovar, Ms. Ekberg, and Dr. Reddy reported no relevant financial relationships. Dr. Sarwer received grant funding from the National Institute of Dental and Craniofacial Research and National Institute of Diabetes and Digestive and Kidney Diseases. He has consulting relationships with Novo Nordisk and Twenty30 Health. He is an associate editor for Obesity Surgery and editor in chief of Obesity Science & Practice.

Endocrinologists and other medical professionals can help by not engaging in “weight and body shaming,” Dr. Tovar said.
She recommends physicians “encourage patients to tune in to their own bodies, helping them become more aware of how different foods affect their physical and emotional well-being.”
Set realistic expectations through “open, nonjudgmental conversations about the complexities of metabolism, weight, and health.”
Dr. Tovar advises rather than focusing on weight loss as the primary goal, physicians should focus on health markers such as blood glucose, energy levels, mental well-being, and physical fitness.
Prioritize “listening over lecturing.” Begin with empathy, asking questions such as “How do you feel about your health right now? What changes have you noticed in your body lately?” Doing this “creates space for the patient to express their concerns without feeling judged or shamed.”
Refer patients to a mental health professional when a patient exhibits signs of disordered eating or poor body image or when emotional factors are playing a significant role in the relationship with food and weight. “If a patient is caught in a cycle of dieting and weight gain, struggles with binge eating, or displays symptoms of depression or anxiety related to body, then psychological help is crucial.”
Ultimately, the goal of treatment “should be to provide a safe, supportive environment where patients can heal — not just physically but also emotionally and mentally,” Dr. Tovar added.

Many people who lose weight, whether through diet and lifestyle changes, medication, or bariatric surgery, recognize their body has changed. While they also experience improvements in quality of life and psychosocial areas, that’s not true for everyone. Some patients don’t “see” they’ve lost weight — a phenomenon referred to as “phantom fat,” “ghost fat,” or “vestigial body image.”
“Most people are happy with their appearance, or at least their body shape, after weight loss — although some are unhappy with the loose, sagging skin that can follow weight loss and seek plastic surgery to remedy that,” David B. Sarwer, PhD, director of the Center for Obesity Research and Education and professor of social and behavioral sciences, Temple University College of Public Health, Philadelphia, told this news organization. “There’s a subset of people who remain dissatisfied with their body image, including their shape.”
This body dissatisfaction of people who lose weight may be long-standing, predating the weight loss, or may be new because weight loss has catalyzed a host of previously unaddressed psychosocial issues. Some may show up at assessments on treatment onset, while others may be detected by monitoring changes during or after weight loss. “Mental health counseling after bariatric surgery is greatly underutilized,” Dr. Sarwer observed.
Ghost Fat
Research has corroborated the lingering self-perception of being “obese” vs “ex-obese.” In one study, patients who had undergone bariatric surgery reported being unable to see the difference in their size and shape 18-30 months following their procedure, despite substantial weight loss.
Some research suggests that rapid weight loss (eg, through bariatric surgery) is more likely to generate the perception of “phantom fat,” but additional research is needed to investigate whether the mode and speed of weight loss affect subsequent body image.
Being habituated to one’s former appearance may play a role, Dr. Sarwer suggested. “We see this not only with weight loss but with other body-altering procedures. It takes the brain time to catch up to the new appearance. In rhinoplasty, for example, it may take patients a while before they become accustomed to looking at their new face in the mirror after decades of looking at a more prominent nose.”
Years of Social Stigma
It may also take time for people to overcome years of enduring the stigma of obesity.
There are “pervasive” negative attitudes implying that individuals who are overweight and/or obese are “lazy, weak-willed, lacking in self-discipline and willpower” — a problem compounded by social media and media in general, which present unrealistic, glorified body images and disparaging messages about those with weight problems.
“Body image is a construct, rather than what you see in the mirror,” Sheethal Reddy, PhD, a psychologist at the Emory Bariatric Center, Emory University Hospital Midtown, Atlanta, told this news organization. “It’s the mental construct of our physical selves.”
According to Dr. Reddy, body image develops “within a broader societal context and is influenced by the person’s ethnic, racial, and cultural heritage.”
Adolescents are particularly vulnerable to body dissatisfaction. This is compounded in those with obesity, who often experience weight-based victimization and internalized weight-based stigma, compared with adolescents with lower weights. Weight stigma often takes the form of teasing and bullying.
“Appearance-related bullying and teasing during childhood and adolescence can reverberate into adulthood and persist throughout the lifespan,” Dr. Sarwer said. “When we see these patients and ask if they’ve ever been teased or bullied, not only do many say yes but it takes them back to those moments, to that origin story, and they remember someone saying something mean, cruel, and hurtful.”
Stigmatizing experiences can affect subjective body image, even after the weight has been lost and the person’s body is objectively thinner. Research comparing individuals who were overweight and lost weight to individuals who are currently overweight and haven’t lost weight and individuals who were never overweight suggests that “vestigial” body disparagement may persist following weight loss — especially in those with early-onset obesity.
The Role of Genetics
Genetics may contribute to people’s self-perception and body dissatisfaction, both before and after weight loss. A study of 827 community-based adolescents examined the association between polygenic risk scores (PRS) for body mass index (BMI) and type 2 diabetes and symptoms of body dissatisfaction and depression.
“Given the significant genetic role in BMI, we wanted to explore whether genetic risk for BMI might also predict body dissatisfaction,” lead author Krista Ekberg, MS, a doctoral candidate in clinical psychology, Rosalind Franklin University of Medicine and Science, North Chicago, Illinois, told this news organization.
Genetic influences on BMI, as measured by PRS, were significantly associated with both phenotypic BMI and body dissatisfaction. “The association between PRS and body dissatisfaction was largely explained by BMI, suggesting that BMI itself accounts for much of the link between genetic risk and body dissatisfaction.”
Psychiatric History and Trauma
Adverse experiences, particularly sexual or physical abuse, may also account for body dissatisfaction after weight loss. “When some people with a history of this type of abuse lose a large amount of weight — typically after bariatric surgery — they often go through a period of emotional turbulence,” Dr. Sarwer said.
Childhood maltreatment can also be associated with body image disturbances in adulthood, according to a meta-analysis of 12 studies, encompassing 15,481 participants. Sexual abuse is “surprisingly common” among patients with obesity, according to Dr. Sarwer. A chart review of 131 patients revealed that 60% of those who reported a history of rape or sexual molestation were ≥ 50 pounds overweight vs only 28% of age- and sex-matched controls without a history of abuse. Other studies have corroborated these findings.
Excess weight can serve an “adaptive function,” Dr. Sarwer noted. It can be a self-protective mechanism that “insulates” them from sexual advances by potential romantic partners or abusers. Some may find that, after weight loss, repressed memories of a sexual assault surface as a result of the newer, more “attractive” appearance. Feeling vulnerable in their thinner bodies, they may need to regard themselves as overweight to maintain that feeling of “protection.” Weight loss may also trigger memories, flashbacks, or nightmares, as people return to a weight at which they were abused.
Dissociation is another mechanism linking trauma with post–weight loss body dysmorphia, Supatra Tovar, PsyD, RD, a clinical psychologist and registered dietitian with a practice in California, told this news organization. Dissociation from the body is often a coping mechanism for dealing with an overwhelming traumatic experience.
Individuals with a history of depression, anxiety, or posttraumatic stress disorder have higher levels of body dysmorphia, both before and after weight loss. One study found that patients undergoing bariatric surgery who had some type of psychopathology and other psychological risk factors were significantly more likely to report body image concerns 3 months after the surgery. Body image concerns were also more common in patients with preoperative depression, current psychotropic medication use, and a history of outpatient therapy or psychotropic medication use.
“Depression, anxiety, and trauma play a role in how you see yourself and how you carry yourself,” Dr. Reddy said. “This is wrapped up in any type of psychopathology. Being depressed is like looking at yourself through a cloud. It’s the opposite of ‘rose-colored glasses’ and instead, looking at yourself through a negative lens.”
Diagnosis and Interventions
Some helpful tools to assess the presence and extent of weight dissatisfaction and body dysmorphia include the Eating Disorder Inventory — Body Dissatisfaction Subscale and the Body Shape Questionnaire. It’s also important to take into account “the extent to which people are invested in their appearance psychologically,” Dr. Sarwer advised. The AO subscale of the Multidimensional Body-Self Relations Questionnaire generally assesses this. The Body Image Quality of Life Inventory assesses how and to what extent the perceived body image affects the person’s quality of life.
Experts recommend cognitive behavioral therapy (CBT) as an evidence-based intervention for body image issues, including those following weight loss.
“There’s an extensive CBT body image therapy program specifically tailored to the needs of overweight and obese individuals,” Dr. Sarwer said. “We don’t ignore historical variables that may have contributed to the problem, like early bullying, but we encourage people to think about what’s going on in their day-to-day life today. We drill down not only into the maladaptive behaviors but also the cognition and beliefs that may be erroneous but underlie these behaviors.”
The aim of CBT is to “modify irrational and dysfunctional thoughts, emotions, and behaviors through techniques such as self-monitoring, cognitive structuring, psychoeducation, desensitization, and exposure and response prevention.” The program laid out in Cash’s body image workbook includes eight steps. (Figure).
Weight Loss Doesn’t Automatically Equate With Happiness
Another realistic expectation runs counter to a common misperception that becoming thin will automatically translate into becoming happier. That’s not always the case, according to Dr. Tovar.
“If you haven’t worked deeply on addressing self-compassion and understanding that who you are at the core has nothing to do with your physical appearance, you can have an empty feeling once you’ve reached this point,” she said. “You still don’t know who you are and what you’re contributing to the world [because] you’ve been so focused on losing weight.”
Weight loss can also “unmask” questions about self-worth, even when receiving compliments about one’s “improved” appearance. “Praise and compliments after weight loss can be a double-edged sword,” Dr. Tovar observed. “You might think, ‘I wasn’t accepted or praised when I was overweight. The only way to be acceptable or validated is by losing weight, so I have to continue losing weight.’ ” This fuels fear of regaining the weight and can lead to continuing to see oneself as overweight, perhaps as a way to stay motivated to continue with weight loss. “Feeling that one’s value depends on remaining thin hampers body satisfaction,” she said.
Dr. Tovar, author of the book Deprogram Diet Culture: Rethink Your Relationship with Food, Heal Your Mind, and Live a Diet-Free Life, encourages people to shift the emphasis from weight loss to a holistic focus on self-worth and to explore obstacles to those feelings both before and after weight loss.

Vancomycin AUC-Dosing Initiative at a Regional Antibiotic Stewardship Collaborative
Antimicrobial resistance is a global threat and burden to health care, with > 2.8 million antibiotic-resistant infections occurring annually in the United States.1 To combat this issue and improve patient care, the US Department of Veterans Affairs (VA) has implemented antimicrobial stewardship programs (ASPs) across its health care systems. ASPs are multidisciplinary teams that promote evidence-based use of antimicrobials through activities supporting appropriate selection, dosing, route, and duration of antimicrobial therapy. ASP best practices are also included in the Joint Commission and Centers for Medicare and Medicaid Services accreditation standards.2
The foundational charge for VA facilities to develop and maintain ASPs was outlined in 2014 and updated in 2023 in the Veterans Health Administration (VHA) Directive 1031 on antimicrobial stewardship programs.2 This directive outlines specific requirements for all VA ASPs, including personnel, staffing levels, and the roles and responsibilities of all team members. VHA now requires that Veterans Integrated Services Networks (VISNs) establish robust ASP collaboratives. A VISN ASP collaborative consists of stewardship champions from each VA medical center in the VISN and is designed to support, develop, and enhance ASP programs across all facilities within that VISN.2 Some VISNs may lack an ASP collaborative altogether, and others with existing groups may seek ways to expand their collaboratives in line with the updated directive. Prior to VHA Directive 1031, the VA Sunshine Healthcare Network (VISN 8) established an ASP collaborative. This article describes the structure and activities of the VISN 8 ASP collaborative and highlights a recent VISN 8 quality assurance initiative related to vancomycin area under the curve (AUC) dosing that illustrates how ASP collaboratives can enhance stewardship and clinical care across broad geographic areas.
VISN 8 ASP
The VHA, the largest integrated US health care system, is divided into 18 VISNs that provide regional systems of care to enhance access and meet the local health care needs of veterans.3 VISN 8 serves > 1.5 million veterans across 165,759 km2 in Florida, South Georgia, Puerto Rico, and the US Virgin Islands.4 The network is composed of 7 health systems with 8 medical centers and > 60 outpatient clinics. These facilities provide comprehensive acute, primary, and specialty care, as well as mental health and extended care services in inpatient, outpatient, nursing home, and home care settings.4
The 2023 VHA Directive 1031 update recognizes the importance of VISN-level coordination of ASP activities to enhance the standardization of care and build partnerships in stewardship across all levels of care. The VISN 8 ASP collaborative workgroup (ASPWG) was established in 2015. Consistent with Directive 1031, the ASPWG is guided by clinician and pharmacist VISN leads. These leads serve as subject matter experts, facilitate access to resources, establish VISN-level consensus, and enhance communication among local ASP champions at medical centers within the VISN. All 7 health systems include = 1 ASP champion (clinician or pharmacist) in the ASPWG. Ad hoc members, whose routine duties are not solely focused on antimicrobial stewardship, contribute to specific stewardship projects as needed. For example, the ASPWG has included internal medicine, emergency department, community living center pharmacists, representatives from pharmacy administration, and trainees (pharmacy students and residents, and infectious diseases fellows) in antimicrobial stewardship initiatives. The inclusion of non-ASP champions is not discussed in VHA Directive 1031. However, these members have made valuable contributions to the ASPWG.
The ASPWG meets monthly. Agendas and priorities are developed by the VISN pharmacist and health care practitioner (HCP) leads. Monthly discussions may include but are not limited to a review of national formulary decisions, VISN goals and metrics, infectious diseases hot topics, pharmacoeconomic initiatives, strong practice presentations, regulatory and accreditation preparation, preparation of tracking reports, as well as the development of both patient-level and HCPlevel tools, resources, and education materials. This forum facilitates collaborative learning: members process and synthesize information, share and reframe ideas, and listen to other viewpoints to gain a complete understanding as a group.5 For example, ASPWG members have leaned on each other to prepare for Joint Commission accreditation surveys and strengthen the VISN 8 COVID-19 program through the rollout of vaccines and treatments. Other collaborative projects completed over the past few years included a penicillin allergy testing initiative and anti-methicillin-resistant Staphylococcus aureus (MRSA) and pseudomonal medication use evaluations. This team-centric problem-solving approach is highly effective while also fostering professional and social relationships. However, collaboratives could be perceived to have drawbacks. There may be opportunity costs if ASP time is allocated for issues that have already been addressed locally or concerns that standardization might hinder rapid adoption of practices at individual sites. Therefore, participation in each distinct group initiative is optional. This allows sites to choose projects related to their high priority areas and maintain bandwidth to implement practices not yet adopted by the larger group.
The ASPWG tracks metrics related to antimicrobial use with quarterly data presented by the VISN pharmacist lead. Both inpatient and outpatient metrics are evaluated, such as days of therapy per 1000 days and outpatient antibiotic prescriptions per 1000 unique patients. Facilities are benchmarked against their own historical data and other VISN sites, as well as other VISNs across the country. When outliers are identified, facilities are encouraged to conduct local projects to identify reasons for different antimicrobial use patterns and subsequent initiatives to optimize antimicrobial use. Benchmarking against VISN facilities can be useful since VISN facilities may be more similar than facilities in different geographic regions. Each year, the ASPWG reviews the current metrics, makes adjustments to address VISN priorities, and votes for approval of the metrics that will be tracked in the coming year.
Participation in an ASP collaborative streamlines the rollout of ASP and quality improvement initiatives across multiple sites, allowing ASPs to impact a greater number of veterans and evaluate initiatives on a larger scale. In 2019, with the anticipation of revised vancomycin dosing and monitoring guidelines, our ASPWG began to strategize the transition to AUC-based vancomycin monitoring.6 This multisite initiative showcases the strengths of implementing and evaluating practice changes as part of an ASP collaborative.
Vancomycin Dosing
The antibiotic vancomycin is used primarily for the treatment of MRSA infections.6 The 2020 consensus guidelines for vancomycin therapeutic monitoring recommend using the AUC to minimum inhibitory concentration (MIC) ratio as the pharmacodynamic target for serious MRSA infections, with an AUC/MIC goal of 400 to 600 mcg*h/mL.6 Prior guidelines recommended using vancomycin trough concentrations of 15 to 20 mcg/mL as a surrogate for this AUC target. However, subsequent studies have shown that trough-based dosing is associated with higher vancomycin exposures, supratherapeutic AUCs, and increased risk of vancomycin-associated acute kidney injury (AKI).7,8 Therefore, more direct AUC estimation is now recommended.6 The preferred approach for AUC calculations is through Bayesian modeling. Due to limited resources and software availability, many facilities use an alternative method involving 2 postdistributive serum vancomycin concentrations and first-order pharmacokinetic equations. This approach can optimize vancomycin dosing but is more mathematically and logistically challenging. Transitioning from troughto AUC-based vancomycin monitoring requires careful planning and comprehensive staff education.
In 2019, the VISN 8 ASPWG created a comprehensive vancomycin AUC toolkit to facilitate implementation. Components included a pharmacokinetic management policy and procedure, a vancomycin dosing guide, a progress note template, educational materials specific to pharmacy, nursing, laboratory, and medical services, a pharmacist competency examination, and a vancomycin AUC calculator (eAppendix). Each component was developed by a subgroup with the understanding that sites could incorporate variations based on local practices and needs.
The vancomycin AUC calculator was developed to be user-friendly and included safety validation protocols to prevent the entry of erroneous data (eg, unrealistic patient weight or laboratory values). The calculator allowed users to copy data into the electronic health record to avoid manual transcription errors and improve operational efficiency. It offered suggested volume of distribution estimates and 2 methods to estimate elimination constant (Ke ) depending on the patient’s weight.9,10 Creatinine clearance could be estimated using serum creatinine or cystatin C and considered amputation history. The default AUC goal in the calculator was 400 to 550 mcg*h/mL. This range was chosen based on consensus guidelines, data suggesting increased risk of AKI with AUCs > 515 mcg*h/mL, and the preference for conservative empiric dosing in the generally older VA population.11 The calculator suggested loading doses of about 25 mg/kg with a 2500 mg limit. VHA facilities could make limited modifications to the calculator based on local policies and procedures (eg, adjusting default infusion times or a dosing intervals).
The VISN 8 Pharmacy Pharmacokinetic Dosing Manual was developed as a comprehensive document to guide pharmacy staff with dosing vancomycin across diverse patient populations. This document included recommendations for renal function assessment, patient-specific considerations when choosing an empiric vancomycin dose, methods of ordering vancomycin peak, trough, and surveillance levels, dose determination based on 2 levels, and other clinical insights or frequently asked questions.
ASPWG members presented an accredited continuing education webinar for pharmacists, which reviewed the rationale for AUC-targeted dosing, changes to the current pharmacokinetic dosing program, case-based scenarios across various patient populations, and potential challenges associated with vancomycin AUC-based dosing. A recording of the live training was also made available. A vancomycin AUC dosing competency test was developed with 11 basic pharmacokinetic and case-based questions and comprehensive explanations provided for each answer.
VHA facilities implemented AUC dosing in a staggered manner, allowing for lessons learned at earlier adopters to be addressed proactively at later sites. The dosing calculator and education documents were updated iteratively as opportunities for improvement were discovered. ASPWG members held local office hours to address questions or concerns from staff at their facilities. Sharing standardized materials across the VISN reduced individual site workload and complications in rolling out this complex new process.
VISN-WIDE QUALITY ASSURANCE
At the time of project conception, 4 of 7 VISN 8 health systems had transitioned to AUC-based dosing. A quality assurance protocol to compare patient outcomes before and after changing to AUC dosing was developed. Each site followed local protocols for project approval and data were deidentified, collected, and aggregated for analysis.
The primary objectives were to compare the incidence of AKI and persistent bacteremia and assess rates of AUC target attainment (400-600 mcg*h/mL) in the AUC-based and trough-based dosing groups.6 Data for both groups included anthropomorphic measurements, serum creatinine, amputation status, vancomycin dosing, and infection characteristics. The X2 test was used for categorical data and the t test was used for continuous data. A 2-tailed α of 0.05 was used to determine significance. Each site sequentially reviewed all patients receiving ≥ 48 hours of intravenous vancomycin over a 3-month period and contributed up to 50 patients for each group. Due to staggered implementation, the study periods for sites spanned 2018 to 2023. A minimum 6-month washout period was observed between the trough and AUC groups at each site. Patients were excluded if pregnant, receiving renal replacement therapy, or presenting with AKI at the time of vancomycin initiation.
There were 168 patients in the AUC group and 172 patients in the trough group (Table 1). The rate of AUC target attainment with the initial dosing regimen varied across sites from 18% to 69% (mean, 48%). Total daily vancomycin exposure was lower in the AUC group compared with the trough group (2402 mg vs 2605 mg, respectively), with AUC-dosed patients being less likely to experience troughs level ≥ 15 or 20 mcg/mL (Table 2). There was a statistically significant lower rate of AKI in the AUC group: 2.4% in the AUC group (range, 2%-3%) vs 10.4% (range 7%-12%) in the trough group (P = .002). Rates of AKI were comparable to those observed in previous interventions.6 There was no statistical difference in length of stay, time to blood culture clearance, or rate of persistent bacteremia in the 2 groups, but these assessments were limited by sample size.
We did not anticipate such variability in initial target attainment across sites. The multisite quality assurance design allowed for qualitative evaluation of variability in dosing practices, which likely arose from sites and individual pharmacists having some flexibility in adjusting dosing tool parameters. Further analysis revealed that the facility with low initial target attainment was not routinely utilizing vancomycin loading doses. Sites routinely use robust loading doses achieved earlier and more consistent target attainment. Some sites used a narrower AUC target range in certain clinical scenarios (eg, > 500 mcg*h/mL for septic patients and < 500 mcg*h/mL for patients with less severe infections) rather than the 400 to 550 mcg*h/mL range for all patients. Sites targeting broader AUC ranges for all patients had higher rates of target attainment. Reviewing differences among sites allowed the ASPWG to identify best practices to optimize future care.
CONCLUSIONS
VHA ASPs must meet the standards outlined in VHA Directive 1031, including the new requirement for each VISN to develop an ASP collaborative. The VISN 8 ASPWG demonstrates how ASP champions can collaborate to solve common issues, complete tasks, explore new infectious diseases concepts, and impact large veteran populations. Furthermore, ASP collaboratives can harness their collective size to complete robust quality assurance evaluations that might otherwise be underpowered if completed at a single center. A limitation of the collaborative model is that a site with a robust ASP may already have specific practices in place. Expanding the ASP collaborative model further highlights the VHA role as a nationwide leader in ASP best practices.

This forum facilitates collaborative learning: members process and synthesize information, share and reframe ideas, and listen to other viewpoints to gain a complete understanding as a group.5 For example, ASPWG members have leaned on each other to prepare for Joint Commission accreditation surveys and strengthen the VISN 8 COVID-19 program through the rollout of vaccines and treatments. Other collaborative projects completed over the past few years included a penicillin allergy testing initiative and anti-methicillin-resistant Staphylococcus aureus (MRSA) and pseudomonal medication use evaluations. This team-centric problem-solving approach is highly effective while also fostering professional and social relationships. However, collaboratives could be perceived to have drawbacks. There may be opportunity costs if ASP time is allocated for issues that have already been addressed locally or concerns that standardization might hinder rapid adoption of practices at individual sites. Therefore, participation in each distinct group initiative is optional. This allows sites to choose projects related to their high priority areas and maintain bandwidth to implement practices not yet adopted by the larger group.
The ASPWG tracks metrics related to antimicrobial use with quarterly data presented by the VISN pharmacist lead. Both inpatient and outpatient metrics are evaluated, such as days of therapy per 1000 days and outpatient antibiotic prescriptions per 1000 unique patients. Facilities are benchmarked against their own historical data and other VISN sites, as well as other VISNs across the country. When outliers are identified, facilities are encouraged to conduct local projects to identify reasons for different antimicrobial use patterns and subsequent initiatives to optimize antimicrobial use. Benchmarking against VISN facilities can be useful since VISN facilities may be more similar than facilities in different geographic regions. Each year, the ASPWG reviews the current metrics, makes adjustments to address VISN priorities, and votes for approval of the metrics that will be tracked in the coming year.
Participation in an ASP collaborative streamlines the rollout of ASP and quality improvement initiatives across multiple sites, allowing ASPs to impact a greater number of veterans and evaluate initiatives on a larger scale. In 2019, with the anticipation of revised vancomycin dosing and monitoring guidelines, our ASPWG began to strategize the transition to AUC-based vancomycin monitoring.6 This multisite initiative showcases the strengths of implementing and evaluating practice changes as part of an ASP collaborative.
Vancomycin Dosing
The antibiotic vancomycin is used primarily for the treatment of MRSA infections.6 The 2020 consensus guidelines for vancomycin therapeutic monitoring recommend using the AUC to minimum inhibitory concentration (MIC) ratio as the pharmacodynamic target for serious MRSA infections, with an AUC/MIC goal of 400 to 600 mcg*h/mL.6 Prior guidelines recommended using vancomycin trough concentrations of 15 to 20 mcg/mL as a surrogate for this AUC target. However, subsequent studies have shown that trough-based dosing is associated with higher vancomycin exposures, supratherapeutic AUCs, and increased risk of vancomycin-associated acute kidney injury (AKI).7,8 Therefore, more direct AUC estimation is now recommended.6 The preferred approach for AUC calculations is through Bayesian modeling. Due to limited resources and software availability, many facilities use an alternative method involving 2 postdistributive serum vancomycin concentrations and first-order pharmacokinetic equations. This approach can optimize vancomycin dosing but is more mathematically and logistically challenging. Transitioning from troughto AUC-based vancomycin monitoring requires careful planning and comprehensive staff education.
In 2019, the VISN 8 ASPWG created a comprehensive vancomycin AUC toolkit to facilitate implementation. Components included a pharmacokinetic management policy and procedure, a vancomycin dosing guide, a progress note template, educational materials specific to pharmacy, nursing, laboratory, and medical services, a pharmacist competency examination, and a vancomycin AUC calculator (eAppendix). Each component was developed by a subgroup with the understanding that sites could incorporate variations based on local practices and needs.
The vancomycin AUC calculator was developed to be user-friendly and included safety validation protocols to prevent the entry of erroneous data (eg, unrealistic patient weight or laboratory values). The calculator allowed users to copy data into the electronic health record to avoid manual transcription errors and improve operational efficiency. It offered suggested volume of distribution estimates and 2 methods to estimate elimination constant (Ke ) depending on the patient’s weight.9,10 Creatinine clearance could be estimated using serum creatinine or cystatin C and considered amputation history. The default AUC goal in the calculator was 400 to 550 mcg*h/mL. This range was chosen based on consensus guidelines, data suggesting increased risk of AKI with AUCs > 515 mcg*h/mL, and the preference for conservative empiric dosing in the generally older VA population.11 The calculator suggested loading doses of about 25 mg/kg with a 2500 mg limit. VHA facilities could make limited modifications to the calculator based on local policies and procedures (eg, adjusting default infusion times or a dosing intervals).
The VISN 8 Pharmacy Pharmacokinetic Dosing Manual was developed as a comprehensive document to guide pharmacy staff with dosing vancomycin across diverse patient populations. This document included recommendations for renal function assessment, patient-specific considerations when choosing an empiric vancomycin dose, methods of ordering vancomycin peak, trough, and surveillance levels, dose determination based on 2 levels, and other clinical insights or frequently asked questions.
ASPWG members presented an accredited continuing education webinar for pharmacists, which reviewed the rationale for AUC-targeted dosing, changes to the current pharmacokinetic dosing program, case-based scenarios across various patient populations, and potential challenges associated with vancomycin AUC-based dosing. A recording of the live training was also made available. A vancomycin AUC dosing competency test was developed with 11 basic pharmacokinetic and case-based questions and comprehensive explanations provided for each answer.
VHA facilities implemented AUC dosing in a staggered manner, allowing for lessons learned at earlier adopters to be addressed proactively at later sites. The dosing calculator and education documents were updated iteratively as opportunities for improvement were discovered. ASPWG members held local office hours to address questions or concerns from staff at their facilities. Sharing standardized materials across the VISN reduced individual site workload and complications in rolling out this complex new process.
VISN-WIDE QUALITY ASSURANCE
At the time of project conception, 4 of 7 VISN 8 health systems had transitioned to AUC-based dosing. A quality assurance protocol to compare patient outcomes before and after changing to AUC dosing was developed. Each site followed local protocols for project approval and data were deidentified, collected, and aggregated for analysis.
The primary objectives were to compare the incidence of AKI and persistent bacteremia and assess rates of AUC target attainment (400-600 mcg*h/mL) in the AUC-based and trough-based dosing groups.6 Data for both groups included anthropomorphic measurements, serum creatinine, amputation status, vancomycin dosing, and infection characteristics. The X2 test was used for categorical data and the t test was used for continuous data. A 2-tailed α of 0.05 was used to determine significance. Each site sequentially reviewed all patients receiving ≥ 48 hours of intravenous vancomycin over a 3-month period and contributed up to 50 patients for each group. Due to staggered implementation, the study periods for sites spanned 2018 to 2023. A minimum 6-month washout period was observed between the trough and AUC groups at each site. Patients were excluded if pregnant, receiving renal replacement therapy, or presenting with AKI at the time of vancomycin initiation.
There were 168 patients in the AUC group and 172 patients in the trough group (Table 1). The rate of AUC target attainment with the initial dosing regimen varied across sites from 18% to 69% (mean, 48%). Total daily vancomycin exposure was lower in the AUC group compared with the trough group (2402 mg vs 2605 mg, respectively), with AUC-dosed patients being less likely to experience troughs level ≥ 15 or 20 mcg/mL (Table 2). There was a statistically significant lower rate of AKI in the AUC group: 2.4% in the AUC group (range, 2%-3%) vs 10.4% (range 7%-12%) in the trough group (P = .002). Rates of AKI were comparable to those observed in previous interventions.6 There was no statistical difference in length of stay, time to blood culture clearance, or rate of persistent bacteremia in the 2 groups, but these assessments were limited by sample size.
We did not anticipate such variability in initial target attainment across sites. The multisite quality assurance design allowed for qualitative evaluation of variability in dosing practices, which likely arose from sites and individual pharmacists having some flexibility in adjusting dosing tool parameters. Further analysis revealed that the facility with low initial target attainment was not routinely utilizing vancomycin loading doses. Sites routinely use robust loading doses achieved earlier and more consistent target attainment. Some sites used a narrower AUC target range in certain clinical scenarios (eg, > 500 mcg*h/mL for septic patients and < 500 mcg*h/mL for patients with less severe infections) rather than the 400 to 550 mcg*h/mL range for all patients. Sites targeting broader AUC ranges for all patients had higher rates of target attainment. Reviewing differences among sites allowed the ASPWG to identify best practices to optimize future care.
CONCLUSIONS
VHA ASPs must meet the standards outlined in VHA Directive 1031, including the new requirement for each VISN to develop an ASP collaborative. The VISN 8 ASPWG demonstrates how ASP champions can collaborate to solve common issues, complete tasks, explore new infectious diseases concepts, and impact large veteran populations. Furthermore, ASP collaboratives can harness their collective size to complete robust quality assurance evaluations that might otherwise be underpowered if completed at a single center. A limitation of the collaborative model is that a site with a robust ASP may already have specific practices in place. Expanding the ASP collaborative model further highlights the VHA role as a nationwide leader in ASP best practices.
Antimicrobial resistance is a global threat and burden to health care, with > 2.8 million antibiotic-resistant infections occurring annually in the United States.1 To combat this issue and improve patient care, the US Department of Veterans Affairs (VA) has implemented antimicrobial stewardship programs (ASPs) across its health care systems. ASPs are multidisciplinary teams that promote evidence-based use of antimicrobials through activities supporting appropriate selection, dosing, route, and duration of antimicrobial therapy. ASP best practices are also included in the Joint Commission and Centers for Medicare and Medicaid Services accreditation standards.2
The foundational charge for VA facilities to develop and maintain ASPs was outlined in 2014 and updated in 2023 in the Veterans Health Administration (VHA) Directive 1031 on antimicrobial stewardship programs.2 This directive outlines specific requirements for all VA ASPs, including personnel, staffing levels, and the roles and responsibilities of all team members. VHA now requires that Veterans Integrated Services Networks (VISNs) establish robust ASP collaboratives. A VISN ASP collaborative consists of stewardship champions from each VA medical center in the VISN and is designed to support, develop, and enhance ASP programs across all facilities within that VISN.2 Some VISNs may lack an ASP collaborative altogether, and others with existing groups may seek ways to expand their collaboratives in line with the updated directive. Prior to VHA Directive 1031, the VA Sunshine Healthcare Network (VISN 8) established an ASP collaborative. This article describes the structure and activities of the VISN 8 ASP collaborative and highlights a recent VISN 8 quality assurance initiative related to vancomycin area under the curve (AUC) dosing that illustrates how ASP collaboratives can enhance stewardship and clinical care across broad geographic areas.
VISN 8 ASP
The VHA, the largest integrated US health care system, is divided into 18 VISNs that provide regional systems of care to enhance access and meet the local health care needs of veterans.3 VISN 8 serves > 1.5 million veterans across 165,759 km2 in Florida, South Georgia, Puerto Rico, and the US Virgin Islands.4 The network is composed of 7 health systems with 8 medical centers and > 60 outpatient clinics. These facilities provide comprehensive acute, primary, and specialty care, as well as mental health and extended care services in inpatient, outpatient, nursing home, and home care settings.4
The 2023 VHA Directive 1031 update recognizes the importance of VISN-level coordination of ASP activities to enhance the standardization of care and build partnerships in stewardship across all levels of care. The VISN 8 ASP collaborative workgroup (ASPWG) was established in 2015. Consistent with Directive 1031, the ASPWG is guided by clinician and pharmacist VISN leads. These leads serve as subject matter experts, facilitate access to resources, establish VISN-level consensus, and enhance communication among local ASP champions at medical centers within the VISN. All 7 health systems include = 1 ASP champion (clinician or pharmacist) in the ASPWG. Ad hoc members, whose routine duties are not solely focused on antimicrobial stewardship, contribute to specific stewardship projects as needed. For example, the ASPWG has included internal medicine, emergency department, community living center pharmacists, representatives from pharmacy administration, and trainees (pharmacy students and residents, and infectious diseases fellows) in antimicrobial stewardship initiatives. The inclusion of non-ASP champions is not discussed in VHA Directive 1031. However, these members have made valuable contributions to the ASPWG.
The ASPWG meets monthly. Agendas and priorities are developed by the VISN pharmacist and health care practitioner (HCP) leads. Monthly discussions may include but are not limited to a review of national formulary decisions, VISN goals and metrics, infectious diseases hot topics, pharmacoeconomic initiatives, strong practice presentations, regulatory and accreditation preparation, preparation of tracking reports, as well as the development of both patient-level and HCPlevel tools, resources, and education materials.
