Topical Tapinarof Approved for Treating Atopic Dermatitis, Ages 2 and Up
An aryl hydrocarbon receptor agonist, tapinarof cream, 1% was first approved in May 2022 for the topical treatment of plaque psoriasis in adults.
According to a press release from the manufacturer, Organon — which markets tapinarof cream, 1%, under the brand name VTAMA — the new indication for AD is based on results from the ADORING pivotal studies. In ADORING 1, the proportion of patients in the tapinarof cream, 1% treatment group who achieved a score of clear (0) or almost clear (1) and a minimum 2-grade improvement from baseline at week 8 on the Validated Investigator Global Assessment for AD was 45.4%, compared with 13.9% of patients who received vehicle alone. ADORING 2 yielded similar results (46.4% vs 18.0%, respectively; P < .0001 for both associations).
Secondary endpoints measured at week 8 also significantly favored the treatment group over the vehicle group, including the Eczema Area and Severity Index score improvement of at least 75% from baseline and achievement of a ≥ 4-point improvement in the patient-reported Peak Pruritus Numerical Rating Scale from baseline.
The most common adverse reactions (incidence ≥ 1%) were upper respiratory tract infection (12%), folliculitis (9%), lower respiratory tract infection (5%), headache (4%), asthma (2%), vomiting (2%), ear infection (2%), pain in extremity (2%), and abdominal pain (1%), according to the release.
Among 728 patients in the ADORING studies who enrolled in an open-label 48-week extension trial (ADORING 3), 378 entered with or achieved complete disease clearance and discontinued treatment. In this subset of patients, the mean duration of the first treatment-free interval was approximately 80 consecutive days, according to the release.

Daratumumab Confirmed as SOC for AL Amyloidosis
Adding DARA to VCd (D-VCd; Darzalex Faspro; Janssen Biotech) provided deeper and more rapid hematologic response and clinically meaningful and statistically significant improvement in overall survival (OS) and major organ deterioration progression-free survival (MOD-PFS), combined with 40.7% cardiac complete response (CR), first author Efstathios Kastritis, MD, said during presentation of an oral abstract at the American Society of Hematology (ASH) 2024 Annual Meeting.
“The Andromeda study is the first comparing two contemporary regimens that shows a significant survival improvement for patients with AL amyloidosis,” said Kastritis, an associate professor at the National and Kapodistrian University of Athens in Greece. “These findings reaffirm frontline D-VCd as the standard of care in this difficult-to-treat disease.”
The regimen was approved for this indication in 2021 based on prior earlier findings from the Andromeda trial. The current results are from a preplanned analysis for MOD-PFS and OS.
At a median follow-up of 61.4 months, the overall hematologic CR rates were 59.5% and 19.2% among 388 patients randomized to receive D-VCd or VCd, respectively (odds ratio, 6.03), which showed continued improvement with additional DARA vs the 53.3% and 18.1% rates observed at the primary analysis, Kastritis reported.
Time to hematologic CR was 67.5 days and 85.0 days in the treatment groups, respectively, and median duration of hematologic CR was not reached in either group.
A significant 56% improvement was also observed in MOD-PFS (hazard ratio [HR], 0.44). Median MOD-PFS was not reached in the D-VCd group and was 30.3 months in the VCd group.
A significant 38% improvement was observed in OS (HR, 0.62), 5-year OS was 76.1% vs 64.7% in the D-VCd and VCd groups, respectively, he said.
“[The OS] benefit occurred even though more than 70% of the patients in the VCd arm who received a subsequent therapy were treated with a DARA-based regimen,” he stressed. “This further emphasizes the importance of using DSTS in the frontline setting.”
Trial participants had newly diagnosed AL amyloidosis with measurable hematologic disease, one or more involved organs, cardiac stage I-IIIA, estimated glomerular filtration rate of at least 20 mL/min, and absence of symptomatic multiple myeloma. They were randomized 1:1 to the two treatment groups. All patients received 1.3 mg/m2 of bortezomib by weekly injection, 300 mg/m2 of cyclophosphamide either by weekly oral or intravenous administration, and 20-40 mg of dexamethasone by weekly oral or intravenous administration for six 28-day cycles.
Those in the D-VCd group also received 1800 mg of DARA coformulated with rHuPH20 as a weekly injection in cycles 1-2, as a biweekly injection in cycles 3-6, and by injection every 4 weeks thereafter for up to 24 28-day cycles.
The median duration of treatment was 21.3 months for D-VCd and 5.3 months for VCd, and of 122 patients who received subsequent therapy, 82 (67%) received subsequent DARA.
Patients who achieved hematologic CR had better MOD-PFS and OS (HR, 0.30 and 0.41, respectively), regardless of the treatment received, he noted, adding that “this further supports that complete hematologic response is a valid early endpoint for the evaluation of anti-monoclonal therapies in AL amyloidosis.”
“I think this is very important for the further development of new treatments in this disease,” he said.
Of note, cardiac and renal response rates in the D-VCd group were about two to three times greater than those in the VCd group at 6, 12, 24, 36, and 48 months, Kastritis said.
Among 235 patients with an evaluable cardiac response, 113 achieved a very good partial response or better, including 76 of 118 (64.4%) in the D-VCd group and 37 of 117 (31.6%) in the VCd group. Of these, 48 (40.7%) and 16 (13.7%) achieved a cardiac CR.
Grade 3 or 4 treatment-emergent adverse events (TEAEs) occurring in at least 5% of patients in the D-VCd and VCd groups, respectively, were lymphopenia (13% and 10%), pneumonia (8% and 4%), hypokalemia (2% and 5%), and peripheral edema (3% and 6%), he noted, adding that systemic administration-related reactions occurred in 14 (7%) of patients receiving D-VCd; all were grade 1 or 2 and most (86%) occurred after the first injection. TEAEs led to treatment discontinuation in 5% and 4% of patients in the groups, respectively.
No new safety signals were observed during the extended follow-up, he said.
Kastritis reported relationships with Pfizer, Genesis Pharma, Sanofi, AbbVie, GSK, Prothena, Janssen, and Amgen.

Upfront Therapy for ITP in Children: New Drug a Game-Changer?
“This is the first time in 30 years that a new drug is being tested for newly diagnosed pediatric ITP,” said the study’s lead author, Kristin A. Shimano, MD, professor of pediatrics at the Benioff Children’s Hospital, University of California San Francisco, in a press statement for the study, presented at the American Society of Hematology (ASH) 2024 Annual Meeting earlier this month.
“We really think that this has the potential to transform the approach to the management of ITP in the newly diagnosed phase with the use of a therapy that can provide sustained hemostatic platelet counts to bridge the time that patients are at risk of bleeding events with the goal to wean off the medication for patients who have a natural resolution of their disease,” Shimano said in her talk.
While children with ITP, a rare autoimmune blood disorder, very often improve without the need for any treatment, some do require intervention, and the condition can become chronic. First-line therapies for those patients commonly include corticosteroids, intravenous immunoglobulin (IVIg), and anti-D globulin; however, side effects can be undesirable, and with their efficacy often temporary, patients can require monitoring and juggling of treatments.
Eltrombopag, an oral, daily thrombopoietin receptor agonist, was approved by the US Food and Drug Administration for children and adults with chronic ITP in 2015; however, research has been lacking on the benefits of the therapy for newly diagnosed pediatric patients.
To investigate the drug’s efficacy at that stage, Shimano and colleagues with the ITP Consortium of North America launched the prospective, open-label Pediatric ITP Newly diagnosed pts Epag vs Standard therapy (PINES) trial, enrolling 118 patients at 23 institutions between May 2019 and January 2024.
All enrollees had been diagnosed with ITP within 3 months and had been determined by their treating hematologist to require pharmacologic treatment.
Of the patients, about 40% were untreated, and 60% had been treated with at least one medication prior to the trial but did not have a lasting response.
The patients were stratified by age and prior treatment and randomized 2:1 to receive either eltrombopag (n = 78) or the investigator’s choice of one of three standard first-line therapies, including prednisone, IVIg, or anti-D globulin at specified doses (n = 40). Overall, 29 in the standard-of-care arm received prednisone and 11 received IVIg. The patients had a median age of 8 years.
For the study’s primary endpoint, patients in the eltrombopag group had a significantly greater sustained response at 12 weeks, defined as having at least three of four platelet counts > 50 × 109/L during weeks 6-12 without the need for rescue treatment, with a rate of 63% vs 35% in the standard-of-care group (P = .0054).
There were no significant differences between the two groups in terms of the proportion of patients with a high bleeding score at weeks 1-4 and week 12.
However, those in the eltrombopag arm had a significantly lower rate of receiving rescue therapy (18% vs 38% with the standard of care; P = .02).
Both groups showed clinically meaningful improvements from baseline in terms of health-related quality of life, as assessed by parent proxy-reported KIT overall scores.
Twenty adverse events that were grade 3 or higher, including six serious adverse events, occurred in each of the study’s arms, with the most common events including headache and epistaxis.
Treatment-related serious adverse events occurred among six patients in the eltrombopag group and one in the control group, but importantly, no thromboembolic events were reported.
One intracranial hemorrhage occurred in the eltrombopag arm.
With eltrombopag having a slower effect than some other treatments, Shimano cautioned that the therapy is not recommended for patients with severe bleeding.
“Patients with grade 4 or 5 bleeding at the time of screening were specifically excluded from the study, so for patients who have very severe bleeding who need to get their platelets up very quickly, this would not be the ideal therapy for them,” she noted.
On the basis of results, the trial was recommended to close early due to efficacy; however, the participants are being followed for a total of 12 months to determine the durability of the responses, including in terms of bleeding events, quality of life, or the development of chronic ITP.
“We have shown that in pediatric patients with newly diagnosed ITP requiring pharmacologic treatment, eltrombopag resulted in a significant, clinically relevant higher rate of a durable platelet response in the absence of rescue treatment as compared with standard first-line therapies,” Shimano said.
“Eltrombopag could certainly be added to the medication choices hematologists consider as they are making treatment decisions with families, and it is an option that could potentially raise platelets for a more sustained period in children with ITP in the newly diagnosed period, which is one of the most difficult times for patients with regard to the impact of the disease on bleeding symptoms and quality of life,” she added.
Commenting on the study, James B. Bussel, MD, emeritus professor of pediatrics, medicine and obstetrics and gynecology at Weill Cornell Medicine in New York City, commented that “generally, a short-term increase in platelets is the biggest challenge, which is getting the patient to the point of not requiring future treatment to get better.”
“If more children can be shown to be going into remission earlier, that would be great,” he said.
While eltrombopag is known to be effective in chronic ITP, a key caveat of its use in newly diagnosed patients is the question of whether patients will get better on their own and feasibly be able to be spared the cost and burden of treatment in the first place.
However, identifying which patients will fit that profile isn’t always easy.
“Exactly which child needs treatment can be hard to determine, and there is some debate about that,” Bussel noted.
“The theoretic standard is that the platelet count doesn’t matter — only whether the patient is bleeding a lot, and then there is debate over treatment based on bleeding scores,” he said.
Quality-of-life issues, such as patients’ ability to take part in activities, are also a key consideration.
“It would be great if eltrombopag can support children who really need it and provide clear unequivocal benefit beyond just increasing the platelet count, but also leading to better quality of life,” Bussel said.
The new findings are “a very encouraging start, but I’d really like to see what the story is at 1 year.”
The study was funded by Novartis, maker of eltrombopag, and sponsored by the ITP Consortium of North America. Shimano disclosed ties with Sanofi, Sobi, Daiichi Sankyo, Novartis, and Pfizer. Bussel reported a relationship with Novartis that ended more than 2 years ago.

The new findings are “a very encouraging start, but I’d really like to see what the story is at 1 year.”
The study was funded by Novartis, maker of eltrombopag, and sponsored by the ITP Consortium of North America. Shimano disclosed ties with Sanofi, Sobi, Daiichi Sankyo, Novartis, and Pfizer. Bussel reported a relationship with Novartis that ended more than 2 years ago.

“This is the first time in 30 years that a new drug is being tested for newly diagnosed pediatric ITP,” said the study’s lead author, Kristin A. Shimano, MD, professor of pediatrics at the Benioff Children’s Hospital, University of California San Francisco, in a press statement for the study, presented at the American Society of Hematology (ASH) 2024 Annual Meeting earlier this month.
“We really think that this has the potential to transform the approach to the management of ITP in the newly diagnosed phase with the use of a therapy that can provide sustained hemostatic platelet counts to bridge the time that patients are at risk of bleeding events with the goal to wean off the medication for patients who have a natural resolution of their disease,” Shimano said in her talk.
While children with ITP, a rare autoimmune blood disorder, very often improve without the need for any treatment, some do require intervention, and the condition can become chronic. First-line therapies for those patients commonly include corticosteroids, intravenous immunoglobulin (IVIg), and anti-D globulin; however, side effects can be undesirable, and with their efficacy often temporary, patients can require monitoring and juggling of treatments.
Eltrombopag, an oral, daily thrombopoietin receptor agonist, was approved by the US Food and Drug Administration for children and adults with chronic ITP in 2015; however, research has been lacking on the benefits of the therapy for newly diagnosed pediatric patients.
To investigate the drug’s efficacy at that stage, Shimano and colleagues with the ITP Consortium of North America launched the prospective, open-label Pediatric ITP Newly diagnosed pts Epag vs Standard therapy (PINES) trial, enrolling 118 patients at 23 institutions between May 2019 and January 2024.
All enrollees had been diagnosed with ITP within 3 months and had been determined by their treating hematologist to require pharmacologic treatment.
Of the patients, about 40% were untreated, and 60% had been treated with at least one medication prior to the trial but did not have a lasting response.
The patients were stratified by age and prior treatment and randomized 2:1 to receive either eltrombopag (n = 78) or the investigator’s choice of one of three standard first-line therapies, including prednisone, IVIg, or anti-D globulin at specified doses (n = 40). Overall, 29 in the standard-of-care arm received prednisone and 11 received IVIg. The patients had a median age of 8 years.
For the study’s primary endpoint, patients in the eltrombopag group had a significantly greater sustained response at 12 weeks, defined as having at least three of four platelet counts > 50 × 109/L during weeks 6-12 without the need for rescue treatment, with a rate of 63% vs 35% in the standard-of-care group (P = .0054).
There were no significant differences between the two groups in terms of the proportion of patients with a high bleeding score at weeks 1-4 and week 12.
However, those in the eltrombopag arm had a significantly lower rate of receiving rescue therapy (18% vs 38% with the standard of care; P = .02).
Both groups showed clinically meaningful improvements from baseline in terms of health-related quality of life, as assessed by parent proxy-reported KIT overall scores.
Twenty adverse events that were grade 3 or higher, including six serious adverse events, occurred in each of the study’s arms, with the most common events including headache and epistaxis.
Treatment-related serious adverse events occurred among six patients in the eltrombopag group and one in the control group, but importantly, no thromboembolic events were reported.
One intracranial hemorrhage occurred in the eltrombopag arm.
With eltrombopag having a slower effect than some other treatments, Shimano cautioned that the therapy is not recommended for patients with severe bleeding.
“Patients with grade 4 or 5 bleeding at the time of screening were specifically excluded from the study, so for patients who have very severe bleeding who need to get their platelets up very quickly, this would not be the ideal therapy for them,” she noted.
On the basis of results, the trial was recommended to close early due to efficacy; however, the participants are being followed for a total of 12 months to determine the durability of the responses, including in terms of bleeding events, quality of life, or the development of chronic ITP.
“We have shown that in pediatric patients with newly diagnosed ITP requiring pharmacologic treatment, eltrombopag resulted in a significant, clinically relevant higher rate of a durable platelet response in the absence of rescue treatment as compared with standard first-line therapies,” Shimano said.
“Eltrombopag could certainly be added to the medication choices hematologists consider as they are making treatment decisions with families, and it is an option that could potentially raise platelets for a more sustained period in children with ITP in the newly diagnosed period, which is one of the most difficult times for patients with regard to the impact of the disease on bleeding symptoms and quality of life,” she added.
Commenting on the study, James B. Bussel, MD, emeritus professor of pediatrics, medicine and obstetrics and gynecology at Weill Cornell Medicine in New York City, commented that “generally, a short-term increase in platelets is the biggest challenge, which is getting the patient to the point of not requiring future treatment to get better.”
“If more children can be shown to be going into remission earlier, that would be great,” he said.
While eltrombopag is known to be effective in chronic ITP, a key caveat of its use in newly diagnosed patients is the question of whether patients will get better on their own and feasibly be able to be spared the cost and burden of treatment in the first place.
However, identifying which patients will fit that profile isn’t always easy.
“Exactly which child needs treatment can be hard to determine, and there is some debate about that,” Bussel noted.
“The theoretic standard is that the platelet count doesn’t matter — only whether the patient is bleeding a lot, and then there is debate over treatment based on bleeding scores,” he said.
Quality-of-life issues, such as patients’ ability to take part in activities, are also a key consideration.
“It would be great if eltrombopag can support children who really need it and provide clear unequivocal benefit beyond just increasing the platelet count, but also leading to better quality of life,” Bussel said.
The new findings are “a very encouraging start, but I’d really like to see what the story is at 1 year.”

Camrelizumab Plus Chemotherapy Boosts Response in Triple-Negative Breast Cancer
TOPLINE:
The combination shows consistent benefits across patient subgroups with a manageable safety profile.
METHODOLOGY:
- A randomized, double-blind, phase 3 trial enrolled 441 females (median age, 48 years) with early or locally advanced triple-negative breast cancer from 40 hospitals in China between November 2020 and May 2023.
- Participants were randomized 1:1 to receive either camrelizumab 200 mg (n = 222) or placebo (n = 219) combined with chemotherapy every 2 weeks, with median follow-up period of 14.4 months.
- Treatment included nab-paclitaxel (100 mg/m²) plus carboplatin (area under curve, 1.5) on days 1, 8, and 15 in 28-day cycles for 16 weeks, followed by epirubicin (90 mg/m²) and cyclophosphamide (500 mg/m²) every 2 weeks for 8 weeks.
- The primary endpoint was pathological complete response, defined as no invasive tumor in breast and lymph nodes.
TAKEAWAY:
- Pathological complete response was achieved in 56.8% (95% CI, 50.0%-63.4%) of patients in the camrelizumab-chemotherapy group vs 44.7% (95% CI, 38.0%-51.6%) in the placebo-chemotherapy group (rate difference, 12.2%; 95% CI, 3.3%-21.2%; P = .004).
- Grade 3 or higher adverse events occurred in 89.2% of camrelizumab-chemotherapy group vs 83.1% in placebo-chemotherapy group, with serious adverse events in 34.7% vs 22.8%, respectively.
- Event-free survival rate at 18 months was 86.6% (95% CI, 79.9%-91.1%) with camrelizumab-chemotherapy vs 83.6% (95% CI, 76.2%-88.9%) with placebo-chemotherapy (hazard ratio [HR], 0.80; 95% CI, 0.46-1.42).
- Disease-free survival rate at 12 months reached 91.9% (95% CI, 85.5%-95.5%) with camrelizumab-chemotherapy compared with 87.8% (95% CI, 80.3%-92.6%) with placebo-chemotherapy (HR, 0.58; 95% CI, 0.27-1.24).
IN PRACTICE:
“The addition of camrelizumab to neoadjuvant chemotherapy significantly improved pathological complete response... The benefits of camrelizumab-chemotherapy with respect to pCR were generally consistent across subgroups,” wrote the authors of the study.
SOURCE:
The study was led by Zhi-Ming Shao, MD, Fudan University Shanghai Cancer Center in Shanghai, China. It was published online on December 13 in JAMA.
LIMITATIONS:
According to the authors, the study’s limitations include short follow-up duration preventing assessment of mature survival data and long-term safety profile, uncertainty about optimal duration of adjuvant camrelizumab treatment, small sample sizes in some subgroups warranting cautious interpretation, and potential limited generalizability as the study was conducted only in Chinese patients with triple-negative breast cancer.
DISCLOSURES:
The study was supported by Jiangsu Hengrui Pharmaceuticals. The authors and funder were involved in data collection, analysis, and interpretation and guaranteed the accuracy, completeness of the data, writing of the report, and the decision to submit the manuscript for publication.

Surveillance Instead of Surgery for Low-Risk DCIS?
At 2 years, investigators on the COMET trial found no clinically meaningful difference in the rates of ipsilateral invasive breast cancer among women randomized to active surveillance vs standard upfront surgery with or without radiation.
The 2-year findings suggest that surveillance is safe in the short term.
“While these results are provocative, I don’t think they’re quite practice-changing yet,” said lead investigator Shelley Hwang, MD, a surgical breast oncologist at Duke University in Durham, North Carolina, who presented the findings at the San Antonio Breast Cancer Symposium (SABCS) 2024.
For one thing, it generally takes longer than 2 years for DCIS to convert to invasive cancer, so it will be important to wait for the planned analyses at 5, 7, and 10 years to make sure there isn’t an excess number of invasive breast cancers in the surveillance arm, Hwang said.
If the results prove durable, however, the findings will likely be “practice-changing” for women who were at least 40 years old and had grade 1 or 2 hormone receptor–positive DCIS at low risk for conversion, Hwang said.
The goal of active surveillance is to prevent unnecessary treatment. During surveillance, lesions are monitored for changes that indicate conversion to more advanced disease, at which point guideline-concordant care begins.
Although DCIS can convert to invasive breast cancer, this doesn’t always happen. As a result, upfront surgery and radiation aren’t necessary for some women.
The COMET trial aimed to determine the short-term safety of an active monitoring approach compared with guideline-concordant care in patients with low-risk DCIS.
The prospective, randomized noninferiority trial included women aged 40 years or older with a new diagnosis of HR–positive grade 1 or grade 2 DCIS without invasive cancer from 100 US Alliance Cancer Cooperative Group clinical trial sites.
In the trial, 484 women with DCIS were randomized to active surveillance — breast mammography and physical exam every 6 months — and 473 were randomized to standard upfront surgery with or without radiation. Overall, 15.7% of participants were Black and 75.0% were White.
Patients in either group could elect to have endocrine therapy, typically over a 5-year period (71% of women in the active monitoring group and 65.5% in the surgery group opted for endocrine therapy).
At 2 years, the cumulative rate of ipsilateral invasive breast cancer was 4.2% in the surveillance group vs 5.9% in the upfront surgery arm.
The study also included a planned per-protocol analysis among 673 patients who strictly followed the study protocol — 246 in the guideline-concordant care group who had received surgery by 6 months and 427 in the surveillance group who initiated the active monitoring protocol at 6 months.
With almost half of patients randomized to surgery declined to have it, which indicates that patients are interested in active monitoring, Hwang said.
At 2 years, the cumulative rate of invasive breast cancer was 3.1% in the active surveillance group vs 8.7% in the upfront surgery arm.
Among patients receiving endocrine therapy, the rate of invasive cancer was 7.15% in the surgery group and 3.21% in the surveillance arm.
Endocrine therapy “may have resulted in a reduced rate of invasive cancer in the active monitoring group,” the study authors noted.
These findings bring up the question of whether endocrine therapy might be just as good as surgery for low-risk DCIS, Hwang added. Given that one third of women undergo mastectomy for DCIS, “I think it’s not an inconsequential question,” Hwang said.
The findings, however, also suggest that surveillance sometimes leaves invasive cancer behind, Hwang explained. Nearly all invasive cancers in the surgery group were found during the initial operation , which may explain the slightly higher rates of invasive cancers in this group. Had the active monitoring group undergone surgery as well, the incidence of invasive cancer may have been the same in both arms, Hwang said.
However, when invasive cancers were removed, there were no significant differences in tumor size, node status, or tumor grade between the two groups, suggesting that there might not be a clinical penalty for delayed intervention with active monitoring, Hwang said.
With more than 10% of patients in the surgery group opting for mastectomy, compared with 1.8% in the active monitoring group, the active monitoring approach may not increase the likelihood of an eventual need for more extensive surgery, the COMET authors explained.
What Strategy Do Patients Prefer?
A companion analysis of patient-reported outcomes in COMET found no meaningful differences in quality of life, symptoms, or anxiety among patients who opted for surveillance over surgery. Results from questionnaires on quality of life, anxiety, depression, and breast cancer concerns were comparable between the two groups, with no evidence of a substantial impact of one approach over the other at 2 years.
“The results of this secondary analysis suggest that the lived experiences of individuals with low-risk DCIS are similar during early follow-up regardless of treatment allocation,” the COMET investigators concluded.
Overall, the findings from COMET provide reassuring short-term data, said Neil Iyengar, MD, a medical breast oncologist at Memorial Sloan Kettering Cancer Center in New York City.
DCIS is not an aggressive cancer, and it’s not going to invade any time soon, so patients have time to consider their options, Iyengar told Medscape Medical News.
The 2-year findings from COMET also help inform patient discussions. “I can tell patients if they decide not to have surgery what the likelihood is that they are going to convert into invasive cancer” after 2 years, he said.
COMET was published in JAMA, and the PRO analysis was published in JAMA Oncology to coincide with the study presentations.
COMET is funded by the Patient-Centered Outcomes Research Institute and others. Hwang is a consultant for Merck and on the advisory board of Clinetic, Exai Bio, and Havah Therapeutics. Iyengar is an advisor and/or researcher for AstraZeneca, Novartis, Pfizer, and other companies.

However, when invasive cancers were removed, there were no significant differences in tumor size, node status, or tumor grade between the two groups, suggesting that there might not be a clinical penalty for delayed intervention with active monitoring, Hwang said.
With more than 10% of patients in the surgery group opting for mastectomy, compared with 1.8% in the active monitoring group, the active monitoring approach may not increase the likelihood of an eventual need for more extensive surgery, the COMET authors explained.
What Strategy Do Patients Prefer?
A companion analysis of patient-reported outcomes in COMET found no meaningful differences in quality of life, symptoms, or anxiety among patients who opted for surveillance over surgery. Results from questionnaires on quality of life, anxiety, depression, and breast cancer concerns were comparable between the two groups, with no evidence of a substantial impact of one approach over the other at 2 years.
“The results of this secondary analysis suggest that the lived experiences of individuals with low-risk DCIS are similar during early follow-up regardless of treatment allocation,” the COMET investigators concluded.
Overall, the findings from COMET provide reassuring short-term data, said Neil Iyengar, MD, a medical breast oncologist at Memorial Sloan Kettering Cancer Center in New York City.
DCIS is not an aggressive cancer, and it’s not going to invade any time soon, so patients have time to consider their options, Iyengar told Medscape Medical News.
The 2-year findings from COMET also help inform patient discussions. “I can tell patients if they decide not to have surgery what the likelihood is that they are going to convert into invasive cancer” after 2 years, he said.
COMET was published in JAMA, and the PRO analysis was published in JAMA Oncology to coincide with the study presentations.
COMET is funded by the Patient-Centered Outcomes Research Institute and others. Hwang is a consultant for Merck and on the advisory board of Clinetic, Exai Bio, and Havah Therapeutics. Iyengar is an advisor and/or researcher for AstraZeneca, Novartis, Pfizer, and other companies.

FDA Approves Cosibelimab for Cutaneous SCC
The programmed death ligand-1 (PD-L1)–blocking antibody is the first and only treatment of its kind approved for advanced CSCC, according to a Checkpoint Therapeutics press release. The FDA approval was based on findings from the multicenter, open-label Study CK-301-101 trial of 109 patients.
In that trial, the objective response rate (ORR) was 47% in 78 patients with metastatic CSCC and 48% in 31 patients with locally advanced CSCC. Median duration of response (DOR) in treated patients was not reached in those with metastatic disease and was 17.7 months in those with locally advanced disease, according to the FDA approval notice.
Adverse reactions occurring in at least 10% of patients included fatigue, musculoskeletal pain, rash, diarrhea, hypothyroidism, constipation, nausea, headache, pruritus, edema, localized infection, and urinary tract infection.
The recommended treatment dose, according to the prescribing information, is 1200 mg given as an intravenous infusion over 60 minutes every 3 weeks until disease progression or unacceptable toxicity.
The agent offers “a differentiated treatment option versus available therapies by binding to PD-L1, rather than programmed death receptor-1 (PD-1), to release the inhibitory effects of PD-L1 on the anti-tumor immune response,” Checkpoint Therapeutics president and chief executive officer James Oliviero stated in the company press release.
The agent has also “demonstrated the ability to induce antibody-dependent cell-mediated cytotoxicity, another potential differentiating feature of the drug compared to existing marketing therapies for CSCC,” Oliviero noted.
“CSCC is the second most common form of skin cancer, and those diagnosed with advanced disease that has recurred or metastasized face a poor prognosis,” stated Emily Ruiz, MD, academic director of the Mohs and Dermatologic Surgery Center at Brigham and Women’s Hospital and director of the High-Risk Skin Cancer Clinic at Dana-Farber Brigham Cancer Center.
“With its dual mechanisms of action and compelling safety profile, this promising drug will provide US oncologists with an important new immunotherapy option for the treatment of CSCC,” she added.

Managing Return-to-Work Barriers for People With Long COVID
Although some patients experience symptoms so severe that they cannot work under any conditions, medical providers and employers can help ensure many patients with long COVID can stay in the workforce.
Long COVID is an infection-associated chronic condition that occurs after SARS-CoV-2 infection and is present for at least 3 months as a continuous, relapsing and remitting, or progressive disease state that affects one or more organ systems. By the end of 2023, at least 400 million people worldwide were estimated to have long COVID.
As members of the Patient-Led Research Collaborative, an international group of more than 60 researchers and health advocates living with long COVID and other infection-associated chronic conditions, we have published one of the first research studies of people with long COVID and their desire to work, the specific needs they have, and what doctors and employers can do to create a path for returning to the workforce.
In our recent paper, we document the barriers and facilitators that individuals living with long COVID experience when attempting to return to work. Our recommendations are based on these findings and include recommendations for both medical providers and employers.
If you are a medical provider:
- Ensure you adequately document your patients’ COVID cases, any long COVID diagnoses, and the functional impairment that long COVID causes. Remember that you can diagnose a patient with long COVID on the basis of their symptoms, and clinical guidelines do not require a record of a positive COVID-19 test, which many patients lack owing to testing barriers.
- Keep up to date on research on long COVID and related infection-associated chronic conditions — for example, through the Project ECHO Long COVID and Fatiguing Illness Recovery Program — and learn about pacing and other treatment options.
If you are an employer:
- Utilize a return-to-work model in which any worker with suspected or confirmed COVID discusses support they may need with their employer when they return to work, with additional check-in dates scheduled to reevaluate supports as needed. Planning for this collaborative and iterative evaluation of return-to-work supports for all workers with COVID-19 is important because it may not be immediately clear to a worker whether they have developed long COVID or are generally recuperating from the illness.
- Do not require medical documentation of a SARS-CoV-2 infection or a Long COVID diagnosis to access accommodations — this is owing to disparities in accessing documentation.
- Tailor job responsibilities, provide remote options, allow flexible hours, and provide longer-range deadlines to account for symptoms for people with long COVID and other infection-associated chronic conditions.
- Provide accommodations to any caregivers of people with long COVID in your workplace.
- If requiring in-person work, make the workplace as safe as possible through ventilation and masking requirements, which will help ensure fewer of your workers develop long COVID, and those already with infection-associated chronic conditions will not get worse.
Our findings and recommendations are specific to long COVID, but they can and should apply to other disabilities. Given that our study’s sample was predominately White and working in jobs that did not require substantial physical labor, additional recommendations may be needed for other populations and workers who have labor-intensive jobs.
510 Study Participants
Long COVID is characterized as a relapsing-remitting illness, often described as episodic, in which an individual’s symptoms may fluctuate. Symptoms can become more or less severe depending on tasks, exertion, and social support in addition to physiologic processes and medical intervention. In our paper, we illustrate how the long COVID return-to-work experience and individuals’ symptoms can be shaped by workplace, home, and medical environments.
We randomly selected 510 participants from a global survey of people living with long COVID and systematically analyzed their open-ended responses using established qualitative analysis methods. In this study, we specifically analyzed what patients wrote about their return-to-work experiences, considering how work experiences and relapsing and remitting long COVID symptoms intersected with personal lives and medical care.
Most of the study participants identified as White, were 30-60 years old (ie, in their key earning years), and had at least a baccalaureate degree. Participants lived in the United States (38%), United Kingdom (25%), continental Europe (8%), Canada (4%), or other countries (25%). Most participants worked in professions that did not require substantial physical labor, and individuals in those fields may experience even greater return-to-work barriers than are reported in this study.
Key Findings
Through our qualitative analysis, we identified four primary return-to-work themes:
1. People living with long COVID have a strong desire and financial need to return to work.
The participants in our study described how they had experienced financial hardship because they could not successfully return to work and may have incurred new expenses with long COVID. They also often wrote how they wanted to return to work because their jobs provided meaning and structure for their lives. Some people in this study shared how they had tried to return to their jobs but relapsed. As a result, they considered leaving the workforce.
2. Workers’ long COVID symptoms intersect with organization of work and home life.
Most of the people in our study were employed in positions that did not require substantial physical labor. Even so, workers described how their long COVID symptoms were exacerbated by some job tasks. Computer screen time; reading dense material or writing (including emails); and conversations and meetings, regardless of whether they were in-person or via phone or video conferencing, could trigger or make symptoms worse. Workers who needed to stand for long periods of time, such as teachers and healthcare workers, and workers who needed to do lifting as part of their jobs described how these requirements were too taxing and could lead to relapses.
Because of the relapsing and remitting nature of many long COVID symptoms, people reported how it could be difficult to predict how job tasks, long hours, or pressing deadlines may exacerbate symptoms, which would require them to take time off work. For these participants, “pushing through” symptoms only made the symptoms worse. However, people in the study who were allowed to work from home reported how pacing, elevating their legs, and conserving energy (especially by not commuting) was key to doing their jobs well.
Some people in the study described how they were only able to return to work because they had substantial support from family or partners at home. These individuals shared how the people they lived with did most of the cooking, cleaning, and other household tasks so that the person living with long COVID could conserve their energy for work. This reorganization of home life notably shifted household tasks and caregiving to other people in the household, but without this shift, the individual’s long COVID symptoms may be too severe to work.
3. People with long COVID experience disbelief and stigma at work and healthcare settings.
Some people in our study described how their colleagues, supervisors, and human resource managers insinuated that they were fabricating or exaggerating their symptoms. This made it hard for workers to communicate what support they needed and could limit access to necessary work accommodations.
Many people in our study also described how medical providers did not believe that they had long COVID despite experiencing debilitating symptoms, often because they did not have a positive COVID-19 test to prove they had had an acute infection. Many people with long COVID may not have a positive COVID-19 test because:
- They could not access a test because testing access was limited at the start of the COVID-19 pandemic, there are transportation and cost barriers to tests, many health insurance providers no longer cover tests; and there are fewer public testing sites since the World Health Organization declared an end to the public health emergency;
- There is a high probability of false-negative results for viral and antibody tests (especially during the first wave of the pandemic and for individuals with limited immune response); and
- People can develop long COVID after asymptomatic acute infection.
Although healthcare providers can provide a long COVID diagnosis without a positive COVID-19 test on the basis of a patient’s presentation of symptoms and clinical history, many people in our study said that their providers would not provide this diagnosis, which restricted access to worker’s compensation, paid time off, and job accommodations.
Many people in the study also reported that their medical providers misdiagnosed them with a mental health disorder, such as anxiety, instead of long COVID. Although some people with long COVID may experience poor mental health as a natural consequence of dealing with a debilitating medical condition or may have neuropsychiatric symptoms as part of their long COVID, long COVID is not caused by an underlying psychiatric illness.
4. Support of medical providers is key to successful return to work for people living with long COVID.
Some people in our study described how they were able to get workplace accommodations or access workers’ compensation or sick leave because their medical providers recognized they had long COVID and provided them with this documentation. Some of these participants did not have a positive COVID-19 test, but their medical providers were able to diagnose them with long COVID on the basis of symptom presentation and clinical history. This documentation was critical for helping workers remain financially stable and able to return to work.
Conclusion
While we continue to search for treatment and cures for long COVID and work to provide a robust social safety net, it is crucial to address the stigma, inaccessibility, and lack of support often experienced by patients in their workplaces. Disabled people have long faced these issues; long COVID may be an opportunity to revolutionize the workplace to ensure an inclusive and accessible environment that can improve the lives of all workers.

- They could not access a test because testing access was limited at the start of the COVID-19 pandemic, there are transportation and cost barriers to tests, many health insurance providers no longer cover tests; and there are fewer public testing sites since the World Health Organization declared an end to the public health emergency;
- There is a high probability of false-negative results for viral and antibody tests (especially during the first wave of the pandemic and for individuals with limited immune response); and
- People can develop long COVID after asymptomatic acute infection.
Although healthcare providers can provide a long COVID diagnosis without a positive COVID-19 test on the basis of a patient’s presentation of symptoms and clinical history, many people in our study said that their providers would not provide this diagnosis, which restricted access to worker’s compensation, paid time off, and job accommodations.
Many people in the study also reported that their medical providers misdiagnosed them with a mental health disorder, such as anxiety, instead of long COVID. Although some people with long COVID may experience poor mental health as a natural consequence of dealing with a debilitating medical condition or may have neuropsychiatric symptoms as part of their long COVID, long COVID is not caused by an underlying psychiatric illness.
4. Support of medical providers is key to successful return to work for people living with long COVID.
Some people in our study described how they were able to get workplace accommodations or access workers’ compensation or sick leave because their medical providers recognized they had long COVID and provided them with this documentation. Some of these participants did not have a positive COVID-19 test, but their medical providers were able to diagnose them with long COVID on the basis of symptom presentation and clinical history. This documentation was critical for helping workers remain financially stable and able to return to work.
Conclusion
While we continue to search for treatment and cures for long COVID and work to provide a robust social safety net, it is crucial to address the stigma, inaccessibility, and lack of support often experienced by patients in their workplaces. Disabled people have long faced these issues; long COVID may be an opportunity to revolutionize the workplace to ensure an inclusive and accessible environment that can improve the lives of all workers.

Does Virtual Care for UTIs Lead to Increased Antibiotic Use Without Better Outcomes?
TOPLINE:
Virtual visits for urinary tract infections (UTIs) increased by more than 600% from 2015 to 2022, with overall UTI encounters growing by 325.9%. The rate of antibiotic dispensation climbed by 227.3% per 1000 patients, outpacing the 159.8% increase in positive urine cultures.
METHODOLOGY:
- Researchers conducted a retrospective cohort study analyzing 1,220,698 UTI encounters among 428,855 nonpregnant women aged ≥ 18 years at Kaiser Permanente Southern California from 2015 to 2022.
- Analysis included outpatient UTI encounters in ambulatory and urgent care settings, excluding emergency and inpatient visits.
- Data collection encompassed demographic information, urine tests, antibiotic dispensation, and UTI diagnoses using International Classification of Diseases, 9th and 10th Revision codes.
- Encounters conducted by physicians, physician assistants, nurse practitioners, and registered nurses through in-person, phone, video, and health portal platforms were evaluated.
TAKEAWAY:
- Virtual encounters grew by 603.2% compared with a 122.8% increase for in-person visits, with virtual visits accounting for 60% (733,263) of all UTI encounters.
- The rate of UTI encounters per 1000 adult female patients increased by 241.6%, while membership in the health system grew by only 24.4%.
- Antibiotics were prescribed without urine testing in 42.5% (519,135) of encounters, and among encounters with both antibiotic dispensation and urine testing, 57.1% (278,903) had a positive culture.
- According to the authors, the increasing rate of antibiotic dispensation surpassed the growth in positive urine culture rates, suggesting increased use of empiric antibiotics.
IN PRACTICE:
“Our findings underscore the importance of balancing telemedicine’s accessibility with maintaining antibiotic stewardship and highlight the need for updated guidelines,” wrote the authors of the study. An accompanying editorial said, “Unfortunately, our misguided conceptual model has led to several decades of UTI research focusing on bad bugs rather than investigating the natural host defenses, how we might boost these, what perturbs the ecosystem, and how microbial defense occurs within the bladder.”

UTI in Primary Care: New Guidelines
This transcript has been edited for clarity.
We often see urinary tract infections in primary care, so these guidelines for the prevention, diagnosis and management of urinary tract infection (UTI) are very helpful to reaffirm our knowledge in the areas where know what we’re doing and update our knowledge in areas of uncertainty. These guidelines are from a new group called the WikiGuidelines group. Ordinarily, I wouldn’t have considered reviewing one of these guidelines, but this one was published in JAMA Network Open. It is evidence based and covers the topic really well.
Diagnosis. Order a urinalysis or a urine culture only if the patient is having symptoms of a UTI. This may seem obvious, but particularly among older individuals, in whom asymptomatic bacteriuria is very common and should not be treated, nonspecific symptoms such as just not feeling well for a day do not warrant obtaining a urinalysis and culture. With no clear way to distinguish between asymptomatic bacteriuria and a true UTI, the first step in making the diagnosis of a UTI accurately is ordering urine studies only in people who have a reasonable chance of having an infection.
The guideline suggests that the diagnosis of UTI should be primarily based on clinical symptoms. A urinalysis can provide further information, but the authors caution us against relying solely on the urinalysis. This is an incredibly important evidence-based recommendation. If you think about it, this supports the common practice of treating UTIs over the phone without having to see the patient or check a urinalysis.
The rationale for this recommendation is that urinalysis is neither a sensitive nor specific test for UTI. The sensitivity of leukocyte esterase is only about 80%, and the specificity is even lower. For positive nitrite on urinalysis, the sensitivity is below 50%, meaning the test would be negative more than half the time when someone actually has a UTI. The specificity of urine nitrate is very high (more than 90%), so if the patient is nitrite positive, they clearly have a UTI. This means that a patient’s report of classic UTI symptoms — urinary burning, frequency, and urgency — is about as good if not a better indicator of a UTI than a urinalysis.
The guidelines also say that in simple uncomplicated cystitis in healthy nonpregnant patients, routine urine cultures are not necessary. A fascinating meta-analysis in JAMA showed that, for women presenting to outpatient clinics with at least two symptoms of UTI and absence of vaginal discharge, there was a greater than 90% likelihood of having acute cystitis. A reminder here, however: If a woman is sexually active and at risk for sexually transmitted infections, then consider testing for STIs as well, because the symptoms of an STI can mimic those of a UTI.
Treatment. Treatment for UTI is usually empiric, with treatment initiated before the culture results are known and with cultures being done only for people with complicated infections, such as pyelonephritis, or with recurrent infections. Decisions about what to use for treatment can be influenced by local patterns of resistance and an individual’s risk factors for antimicrobial resistance. As a general rule, for uncomplicated cystitis, nitrofurantoin for 5 days is a reasonable first-line agent. Evidence of efficacy is good, and the risk for antimicrobial resistance is lower vs using antibiotics for other systemic infections.
Other reasonable first-line agents for uncomplicated cystitis include trimethoprim-sulfamethoxazole (TMP-SMX) for 3 days; fosfomycin (oral) single dose; or a beta-lactam (most commonly a first generation cephalosporin), although evidence for duration is unclear. Also mentioned are two unfamiliar antibiotics: pivmecillinam (a beta-lactam agent recently approved by the Food and Drug Administration [FDA], given for 3 days) and gepotidacin (from a new class of antibiotic that is currently under FDA review). Fluoroquinolones should not usually be first-line agents unless other treatment options are not appropriate.
It’s important to distinguish between uncomplicated cystitis and pyelonephritis. For pyelonephritis (infection of the upper urinary tract), the first decision has to do with setting for care, depending on how sick someone is, and the likelihood of gram-negative bacteremia — all of which help whether the patient needs to be hospitalized for intravenous antibiotics, or can be treated as an outpatient. Determine if they need to be admitted for intravenous antibiotics or whether they can be treated as an outpatient. For outpatient treatment of pyelonephritis, the guideline suggests that TMP-SMX or a first-generation cephalosporin are both reasonable first-line agents, with fluoroquinolones being a reasonable choice as well. Ceftriaxone is recommended for first-line therapy for patients who require intravenous treatment.
People often forget that we can do a lot to prevent UTIs, particularly among women with recurrent UTIs. The prevention of UTIs has both nonpharmacologic and pharmacologic approaches.
Nonpharmacologic prevention. One nonpharmacologic strategy is increasing water intake. A randomized controlled trial in women with recurrent cystitis who drank less than 1.5 L of fluid a day showed that the women randomized to consume an additional 1.5 L of water daily had significantly reduced cystitis frequency — approximately 50%. Because this was the only randomized trial to show this effect, this is not a strong recommendation, but there is very little downside in healthy women, so increasing water intake is a reasonable recommendation.
Another commonly discussed intervention is the use of cranberry products. As it turns out, most prospective studies have shown that cranberry products can reduce the risk for symptomatic UTIs in women with recurrent UTI.
Pharmacologic prevention. For postmenopausal women with recurrent UTI, topical vaginal estrogen has a strong base of evidence — more than 30 randomized trials — supporting its effectiveness in UTI: a 50%-90% reduction in the incidence of recurrent UTIs. Topical estrogen has minimal systemic absorption, and there are no concerning safety signals with respect to either thromboembolic disease or cancer (endometrial or breast).
Methenamine hippurate is also recommended and is FDA-approved for prevention of UTIs. It works by releasing formaldehyde in the urine, leading to bacteriostasis, which is how it leads to a decrease in UTIs. Finally, postcoital or daily administration of TMP-SMX, nitrofurantoin, norfloxacin, and ciprofloxacin all have comparable efficacy for prophylaxis, with a meta-analysis showing a decrease in recurrence rate of approximately 85%. The guideline states that there is insufficient evidence to support the use of either probiotics or D-mannose to prevent UTIs.
This is a wonderful update on a common problem. We all have a lot of clinical experience here.

A 16-Year-Old Hispanic Male with a History of Hyperlipidemia Reports a Pruritic Rash on His Neck and Chest
Discussion
Given the patient’s recent dietary changes, particularly his switch to a ketogenic diet, he was diagnosed with prurigo pigmentosa and treated with doxycycline, which cleared the rash. Prurigo pigmentosa is a rare inflammatory dermatosis characterized by net-like or reticulated pink, and later hyperpigmented, papules and plaques. Although the condition predominantly affects young women of East Asian descent, cases have been reported worldwide, highlighting the importance of considering this diagnosis in diverse populations, including children. Here, we describe a case of prurigo pigmentosa in a young male who had recently adopted a ketogenic diet for weight loss.
The association between prurigo pigmentosa and dietary changes, particularly ketosis, is becoming increasingly recognized. This condition is strongly linked to ketosis, a metabolic state marked by the production of ketone bodies (e.g., beta-hydroxybutyrate and acetoacetate) during carbohydrate restriction, fasting, or ketogenic diets, as seen in our patient. These ketone bodies may act as irritants or trigger oxidative stress and inflammatory cascades in the skin.
Ketoacidosis, particularly in prolonged or intense ketosis, is thought to alter the local skin microenvironment, promoting activation of inflammatory cytokines and immune cells. The ketogenic state is believed to generate oxidative stress through increased free fatty acid oxidation, leading to the production of reactive oxygen species (ROS). ROS can induce apoptosis of keratinocytes and inflammation in the epidermis, which is predominantly mediated by neutrophilic infiltration, as seen in histopathological findings. Elevated levels of pro-inflammatory cytokines, such as interleukin-8 (IL-8) and tumor necrosis factor-alpha (TNF-α), have been implicated in neutrophil recruitment and activation. IL-8 is particularly important for guiding neutrophils to areas of injury.
Secondary hyperpigmentation, a hallmark of this condition, is thought to result from melanin-laden macrophages and persistent melanocyte activation in response to inflammation at the dermo-epidermal junction.
The condition progresses in three stages. In the early stage, lesions appear as pruritic, urticarial plaques. These evolve into crusted erythematous papules and papulovesicles in the middle stage, as observed in our patient. Finally, in the late stage, the lesions mature into smooth, hyperpigmented plaques. Each stage of prurigo pigmentosa has distinct histopathological features.
Differential Diagnosis
The differential diagnosis for prurigo pigmentosa includes several conditions that may present similarly. Allergic contact dermatitis (ACD) can initially mimic the erythematous papules of prurigo pigmentosa, but the absence of a clear allergen exposure and failure to improve with avoidance measures makes ACD less likely. Psoriasis is another possibility, as its erythematous plaques may overlap with prurigo pigmentosa. However, the lack of silvery scales and chronicity makes psoriasis less likely in this case. Eczema, or atopic dermatitis, typically presents with pruritic, ill-defined plaques, often in flexural areas, which were not observed in this patient. Flagellate dermatitis, often caused by exposure to bleomycin or consumption of shiitake mushrooms, can present with linear erythematous lesions resembling prurigo pigmentosa. However, the absence of relevant exposures and a flagellate pattern in this patient rules out this diagnosis.
This case highlights the growing recognition of prurigo pigmentosa in the context of dietary trends, especially ketogenic diets, which have become popular for weight loss and other health benefits. Pediatric populations, in particular, may adopt such diets for various reasons and require careful monitoring, as their physiological responses may differ from those in adults. Prurigo pigmentosa has also been reported in a teenager girl with a history of anorexia nervosa, who was in a ketotic state.
Treatment options for prurigo pigmentosa include antibiotics such as minocycline or doxycycline, or macrolides for 4–10 weeks. Other treatment modalities include dapsone, Q-switch Nd:YAG laser, narrow-band ultraviolet B (UVB) phototherapy, and topical treatments like crisaborole and tacrolimus.
Early recognition of this condition is crucial to avoid unnecessary interventions and to allow for resolution through dietary modification. Dermatologists and pediatricians should maintain a high index of suspicion for prurigo pigmentosa in patients presenting with characteristic eruptions and a history of dietary ketosis.

Discussion
Given the patient’s recent dietary changes, particularly his switch to a ketogenic diet, he was diagnosed with prurigo pigmentosa and treated with doxycycline, which cleared the rash. Prurigo pigmentosa is a rare inflammatory dermatosis characterized by net-like or reticulated pink, and later hyperpigmented, papules and plaques. Although the condition predominantly affects young women of East Asian descent, cases have been reported worldwide, highlighting the importance of considering this diagnosis in diverse populations, including children. Here, we describe a case of prurigo pigmentosa in a young male who had recently adopted a ketogenic diet for weight loss.
The association between prurigo pigmentosa and dietary changes, particularly ketosis, is becoming increasingly recognized. This condition is strongly linked to ketosis, a metabolic state marked by the production of ketone bodies (e.g., beta-hydroxybutyrate and acetoacetate) during carbohydrate restriction, fasting, or ketogenic diets, as seen in our patient. These ketone bodies may act as irritants or trigger oxidative stress and inflammatory cascades in the skin.
Ketoacidosis, particularly in prolonged or intense ketosis, is thought to alter the local skin microenvironment, promoting activation of inflammatory cytokines and immune cells. The ketogenic state is believed to generate oxidative stress through increased free fatty acid oxidation, leading to the production of reactive oxygen species (ROS). ROS can induce apoptosis of keratinocytes and inflammation in the epidermis, which is predominantly mediated by neutrophilic infiltration, as seen in histopathological findings.

Case Report
A 16-year-old Hispanic male with a history of hyperlipidemia presents to his pediatrician's office for a routine well-child check-up. He reports a pruritic rash on his neck and chest that has been present for the past 1.5 weeks. The rash is itchy, and although a cream from Mexico initially helped, it has not been effective recently. The patient mentions that he has increased his gym workouts and has been training for basketball. He has a history of obesity but has lost almost 100 pounds in the last 6 months. Most recently, he has stopped consuming carbohydrates and has been fasting in the mornings.
There is no history of eczema or psoriasis, either in the patient or his family.
Physical Examination
The patient weighs 147 pounds, a significant decrease from his previous weight of 270 pounds 6 months ago. Other vital signs are within normal limits.
On physical examination, the patient presents with net-like, pink, scaly plaques on his neck, with no other rashes on the body (see Pictures 1 and 2).
