Assessment of the Cutaneous Hormone Landscapes and Microbiomes in Vulvar Lichen Sclerosus.

Vulvar lichen sclerosus (VLS) is a progressive skin disease of unknown etiology. In this longitudinal case-control exploratory study, we evaluated the hormonal and microbial landscapes in 18 postmenopausal women (mean [SD] age: 64.4 [8.4]) with vulvar lichen sclerosus and controls. We reevaluated the VLS patients after 10-14 weeks of daily topical Class I steroid. We found that groin cutaneous estrone was lower in vulvar lichen sclerosus versus controls (-22.33, 95% CI -36.96 to -7.70; P = 0.006); cutaneous progesterone was higher (5.73, 95% CI 3.74 to 7.73; P< 0.0001). Forehead 11-deoxycortisol (-0.24, 95% CI -0.42 to -0.06; P = 0.01) and testosterone (-7.22, 95% CI -12.83 to -1.62; P = 0.02) were lower in disease. With treatment, cutaneous estrone (-7.88, 95% CI -44.07 to 28.31; P = 0.62), progesterone (2.02, 95% CI -2.08 to 6.11; P = 0.29), and 11-deoxycortisol (-0.13, 95% CI -0.32 to 0.05; P = 0.15) normalized; testosterone remained suppressed (-7.41, 95% CI -13.38 to -1.43; P = 0.02). 16S rRNA V1-V3 and ITS1 amplicon sequencing revealed bacterial and fungal microbiome alterations in disease. Findings suggest that cutaneous sex hormone and bacterial microbiome alterations may be associated with VLS in postmenopausal women.

Geriatric Genital Dermatology.

As women age, hormonal changes set the stage for a variety of vulvovaginal pathologies. Health care providers in long-term care facilities should be able to recognize and treat these conditions, especially because residents may be unable to communicate their discomfort. The objective of this article is to highlight the major vulvovaginal conditions affecting older women and provide up-to-date information on treatment for providers in long-term care facilities.

Vulvar Lichen Sclerosus Clinical Severity Scales and Histopathologic Correlation: A Case Series.

ABSTRACT: Several vulvar lichen sclerosus (VLS) clinical severity scales have recently been proposed. In this prospective case series, we characterized histopathology in the context of clinical severity in 6 treatment-naïve postmenopausal patients with VLS. The Vulvar Quality of Life Index (VQLI) and an adaptation of the 2018 International Society for the Study of Vulvovaginal Disease Delphi consensus VLS severity score were administered. Vulvar skin punch biopsies were obtained to measure inflammatory density, constituent inflammatory cells, thickness of the stratum corneum and other epidermal layers, dermal edema, and dermal sclerosis. Clinicopathologic correlations were assessed. Two cases demonstrated sparse inflammatory densities, 1 case demonstrated patchy and nodular inflammatory density, 1 case demonstrated dense lichenoid inflammatory density, and 2 cases demonstrated dense lichenoid and epitheliotropic inflammatory densities. Those patients who reported severe pruritus demonstrated the greatest lymphocytic inflammatory densities on histopathological examination. Both cases of ulceration or erosion were associated with severe VQLI scores. Severe VQLI scores were also associated with trends for higher average thickness of the epidermal layers and of dermal sclerosis. Altogether, histopathologic grading of biopsy sites may reflect clinical severity in patients with VLS.

Development of a Skin-Directed Scoring System for Stevens-Johnson Syndrome and Epidermal Necrolysis: A Delphi Consensus Exercise.

Importance: Scoring systems for Stevens-Johnson syndrome and epidermal necrolysis (EN) only estimate patient prognosis and are weighted toward comorbidities and systemic features; morphologic terminology for EN lesions is inconsistent. Objectives: To establish consensus among expert dermatologists on EN terminology, morphologic progression, and most-affected sites, and to build a framework for developing a skin-directed scoring system for EN. Evidence Review: A Delphi consensus using the RAND/UCLA appropriateness criteria was initiated with a core group from the Society of Dermatology Hospitalists to establish agreement on the optimal design for an EN cutaneous scoring instrument, terminology, morphologic traits, and sites of involvement. Findings: In round 1, the 54 participating dermatology hospitalists reached consensus on all 49 statements (30 appropriate, 3 inappropriate, 16 uncertain). In round 2, they agreed on another 15 statements (8 appropriate, 7 uncertain). There was consistent agreement on the need for a skin-specific instrument; on the most-often affected skin sites (head and neck, chest, upper back, ocular mucosa, oral mucosa); and that blanching erythema, dusky erythema, targetoid erythema, vesicles/bullae, desquamation, and erosions comprise the morphologic traits of EN and can be consistently differentiated. Conclusions and Relevance: This consensus exercise confirmed the need for an EN skin-directed scoring system, nomenclature, and differentiation of specific morphologic traits, and identified the sites most affected. It also established a baseline consensus for a standardized EN instrument with consistent terminology.

Sudden Conjunctivitis, Lymphopenia, and Rash Combined With Hemodynamic Changes (SCoRCH) After Trimethoprim-Sulfamethoxazole Use: A Case Series Study of a Hypersensitivity Reaction.

Importance: Trimethoprim-sulfamethoxazole (TMP-SMX) hypersensitivity reaction, ranging from circulatory shock to aseptic meningitis and respiratory failure, is a potentially life-threatening condition with dermatologic relevance. Objective: To describe the mucocutaneous findings and clinical features of TMP-SMX hypersensitivity reaction. Design, Setting, and Participants: This was a retrospective case series study of 7 patients who developed a characteristic rash, hemodynamic changes, and end-organ dysfunction after treatment with TMP-SMX at a large university hospital system during January 2013 to March 2022. Exposures: Treatment with TMP-SMX within 2 weeks of the reaction. Main Outcome and Measures: Descriptions of the condition, including the demographic information of the affected population, the reaction timeline, and mucocutaneous and clinical features. Results: The cohort comprised 7 patients (median [range] age, 20 [15-66] years; 4 female and 3 male). The most common mucocutaneous findings were generalized sunburn-like erythema without scale, conjunctivitis, and mild facial and acral edema. Three patients had previous exposure to TMP-SMX and developed symptoms in 1 day or less, while those without prior exposure presented from 4 to 11 days after drug initiation. Among the 7 patients, 6 had fever, 7 had hypotension, and 7 had tachycardia. All patients had lymphopenia and evidence of end-organ dysfunction with either kidney or liver involvement. Median (range) time to resolution was 72 (48-96) hours. Conclusions and Relevance: This retrospective case series indicates that SCoRCH (sudden conjunctivitis, lymphopenia, and rash combined with hemodynamic changes) should be considered in the differential diagnosis of patients presenting with acute generalized sunburn-like erythema, conjunctivitis, systemic symptoms, and hemodynamic changes in the setting of recent TMP-SMX use.
