RESUMEN

Importance: Disseminated superficial actinic porokeratosis (DSAP) is an inherited or sporadic disorder of keratinization associated with germline variations. There is no effective standard of care therapy for DSAP, but treatment with topical lovastatin combined with cholesterol cream has shown promise. Objectives: To evaluate and compare the safety and efficacy of topical lovastatin 2% plus cholesterol 2% cream (lovastatin-cholesterol) and topical lovastatin 2% cream (lovastatin) alone in adults diagnosed with DSAP. Design, Setting, and Participants: This patient- and assessor-blinded, randomized clinical trial was conducted at the Medical University of South Carolina between August 3, 2020, and April 28, 2021. Nonpregnant adults with a previous clinical or histological diagnosis of DSAP were eligible. Data were blindly analyzed after study completion. Interventions: Participants were randomized to once- or twice-daily application of either lovastatin-cholesterol cream (n = 17) or lovastatin cream (n = 14) to symptomatic regions for 12 weeks. Main Outcomes and Measures: The primary efficacy measure was the effect of the treatment on DSAP at the end of treatment (12 weeks) as measured by the DSAP General Assessment Severity Index (DSAP-GASI; scored from 0-4, with 0 indicating clear and 4 indicating severe). Treatment efficacy was based on investigator-standardized photographs provided by the participants because of the need for evaluation via telehealth during the COVID-19 pandemic. Secondary efficacy measures included patient-reported outcomes, application frequency, and adverse events (AEs). Results: Of the 87 participants screened, 32 were enrolled. One participant randomized to receive lovastatin-cholesterol did not receive the intervention, leaving 17 participants (mean [range] age, 59.2 [40-83] years; 13 females [76.5%]; all White) allocated to receive lovastatin-cholesterol treatment and 14 participants (13 female [92.9%]; mean (range) age, 53.7 [33-71] years; all White) to receive lovastatin treatment. Twelve participants in each treatment group qualified for the analysis. Disease severity decreased from week 1 to week 12 by 50.0% (from 3.08 [95% CI, 2.57-3.60] to 1.54 (95% CI, 1.04-2.05] points on the DSAP-GASI; P < .001) in the lovastatin-cholesterol group and 51.4% (from 2.92 [95% CI, 2.40-3.43] to 1.50 [95% CI, 0.99-2.01] points; P < .001) in the lovastatin group. There was no significant difference between the treatment groups according to application frequency at the end of 12 weeks. Adverse events reported included myalgia (n = 2), elevation in the creatine kinase level (n = 1), application discomfort (n = 4), and rash (n = 1). No serious AEs occurred, and all participants with an AE were able to complete the study. Conclusions and Relevance: This randomized clinical trial found improvements in DSAP severity in both treatment groups, without serious AEs, indicating a limited benefit with the addition of cholesterol. These results suggest that lovastatin cream may be a new primary treatment option for patients diagnosed with DSAP. Trial Registration: ClinicalTrials.gov Identifier: NCT04359823.

RESUMEN

Dermatomyositis (DM) is an autoimmune myopathy with characteristic dermatologic features.1 Tofacitinib is an immunomodulator with proven efficacy against numerous immune-mediated disorders, including rheumatoid arthritis (RA) and psoriasis.2 Several reports have demonstrated oral tofacitinib’s ability to treat the cutaneous and extracutaneous manifestations of refractory dermatomyositis (DM).1,4,5 However, evidence for sustained improvement remains limited.2,3 The goal of this study is to investigate the long-term response of recalcitrant DM to oral and topical tofacitinib at varied dosing regimens.

RESUMEN

BACKGROUND: Pyoderma gangrenosum (PG) is a rare ulcerative skin disease; its etiology is unknown, though it is often associated with autoimmune diseases. Pyoderma gangrenosum results in significant morbidity and exquisite pain that affects health-related quality of life. Wound healing is delayed, and patients often experience relapse. Pyoderma gangrenosum is susceptible to pathergy and deterioration with surgical intervention or other trauma; therefore, treatment includes atraumatic wound care, infection management, and local or systemic immunosuppression. CASE: We describe the use of modified negative pressure wound therapy (NPWT) with intralesional and topical steroids for the treatment of PG in a 15-year-old female patient with ulcerative colitis and a staged J-pouch ileoanal reconstruction. The patient and her family refused all systemic therapy due to prior steroid-associated weight gain. She was unable to tolerate conscious dressing changes, further complicating the treatment plan. Procedural interventions such as NPWT have been used previously for PG; however, they can cause wound pathergy and subsequent wound deterioration. Modified NPWT in conjunction with topical and intralesional steroids induced wound healing without producing pathergy. CONCLUSION: Timely recognition of PG is crucial to appropriate delivery of care. Modified NPWT and localized corticosteroid treatment were key to promoting wound healing in this case of pediatric PG.

RESUMEN

New therapies such as immune checkpoint blockers (ICB) have offered extended survival to patients affected by advanced melanoma. However, ICBs have demonstrated debilitating side effects on the joints, liver, lungs, skin, and gut. Several biomarkers have been identified for their role in predicting which patients better tolerate ICBs. Still, these biomarkers are limited by immunologic and genetic heterogeneity and the complexity of translation into clinical practice. Recent observational studies have suggested eosinophil counts, and serum levels of eosinophil cationic protein are significantly associated with prolonged survival in advanced-stage melanoma. It is likely that eosinophils thereby modulate treatment response through mechanisms yet to be explored. Here, we review the functionality of eosinophils, their oncogenic role in melanoma and discuss how these mechanisms may influence patient response to ICBs and their implications in clinical practice.
