Area Deprivation and Disease Severity in Adult Patients With Discoid Lupus Erythematosus.

Importance: The association of area deprivation with outcomes in discoid lupus erythematosus (DLE) remains poorly understood. Objective: To determine the association between US Census block measures of deprivation and disease severity in adult patients with DLE. Design, Setting, and Participants: This cross-sectional study included 154 patients with DLE seen between January 1, 2007, and January 1, 2024, at a single-center referral-based specialty rheumatologic-dermatology clinic in Philadelphia, Pennsylvania. Patients were aged 18 to 73 years and were enrolled in the University of Pennsylvania's Cutaneous Lupus Erythematosus Database study. Data were analyzed between January 1, 2024, and May 8, 2024. Exposures: Residence in a highly disadvantaged area as geocoded by a state area deprivation index (ADI). Main Outcomes and Measures: The main outcome was DLE disease severity as codified by the validated Cutaneous Lupus Erythematosus Disease Area and Severity Index (CLASI) damage and activity scores. Results: A total of 154 adult patients with DLE (128 women [83%] and 26 men [17%]; mean [SD] age, 43 [13] years; 6 [4%] Asian individuals, 98 [64%] Black individuals, 2 [1%] Hispanic individuals, 46 [30%] White individuals, and 2 individuals [1%] with other race or ethnicity; 78 [51%] with an ADI >5; 43 who currently smoked [28%];and 56 [36%] with concurrent systemic lupus erythematosus) were included in the analysis. By multivariable logistic regression, residence within communities with an ADI greater than 5 was associated with nearly 4-fold greater odds of moderate to severe damage (odds ratio [OR], 3.90; 95% CI, 1.27-12.69] and activity (OR, 3.31; 95% CI, 1.27-9.44). Concurrent cigarette smoking was similarly associated with greater odds of moderate to severe damage (OR, 3.15; 95% CI, 1.09-10.29). After controlling for ADI and other confounders, race was not significantly associated with DLE disease severity. Conclusions and Relevance: The results of this cross-sectional study suggest that geospatial disadvantage is associated with DLE disease severity independent of race. This invites a paradigm shift that considers the social context within which racial disparities are observed, highlighting the potential for geographically targeted interventions and policy changes to improve patient outcomes in DLE.

The impact of hormones in autoimmune cutaneous diseases.

INTRODUCTION: Dermatomyositis, systemic and cutaneous lupus erythematosus have a significantly higher prevalence in women than men, emphasizing the relevance of exploring the relationship between sex hormones and autoimmune skin diseases. This review analyzes the interplay between sex hormones and these two skin diseases. MATERIALS AND METHODS: We performed an extensive literature search using the PubMed database from July to August 2023. Search terms included 'contraceptives', 'pregnancy', 'hormone replacement', 'tamoxifen', and 'aromatase inhibitors'. RESULTS AND DISCUSSION: This comprehensive literature review shows that there remains considerable debate regarding the use of hormonal contraceptives and hormonal replacement therapy in individuals with autoimmune skin conditions. Nonetheless, it is well established that their use is contraindicated in patients with antiphospholipid syndrome or when antiphospholipid antibodies are positive. Individuals experiencing disease flares and uncontrolled symptoms should also avoid these interventions. Pregnancy planning should be timed to coincide with well-managed disease states to minimize obstetric and neonatal complications. Hormonal breast cancer treatment requires close skin monitoring. CONCLUSION: Pregnancy, menopause, contraceptive use, hormone replacement therapy, and breast cancer treatment drugs result in substantial shifts in hormone levels. Additionally, hormone levels are altered by aromatase inhibitors and anti-estrogen medications. These fluctuations can modulate mechanisms influencing autoimmune skin abnormalities.

Novel assessment of lip redness and microcirculation using optical coherence tomography after dermal filler injection.

OBJECTIVES: Lip filler injections are one of the most popular procedures in esthetic dermatology. In this study, we used three-dimensional colorimetric photography to assess lip color and optical coherence tomography-angiography (OCT-A), a noninvasive alternative to histopathology, to evaluate microcirculation after hyaluronic acid (HA) injection. The pain of the injection procedure was also assessed. METHODS: An average of 0.85cc of the total volume of HA with lidocaine was injected into the upper and lower lip of eighteen young (<30yo) and nine postmenopausal healthy women. OCT-A, two-dimensional, and three-dimensional images were acquired immediately before (visit 1) and 15 days after injection (visit 2). Custom-made software was used to analyze the imaging data to detect vessel morphology and redness changes. The Wong-Baker FACES pain rating scale (0-10) was used to score the subject procedural pain. RESULTS: For young and old subjects, three-dimensional lip volume was greater than the injected volume. OCT-A images of the lips showed higher vessel density and thickness, reaching statistical significance in the younger cohort. The overall trend of increased redness assessed by three-dimensional colorimetric imaging and increased vascularity evaluated by OCT-A imaging were similar. However, the correlation was not statistically significant for standard two-dimensional digital photography. The average pain score after the first needle insertion and overall procedure were 2.9 and 3.5, respectively. CONCLUSIONS: The results suggest an increased microvasculature network observed in OCT-A images in young females. The increased blood vessel density and thickness observed by OCT-A after HA lip filler injection is associated with increased lip redness and volume as assessed by colorimetric three-dimensional photography; however, more research is needed to confirm these findings. This study presents OCT-A as a novel noninvasive tool to investigate changes in lip microvascularity after HA filler injection and indicates that HA filler procedures may affect lip vascularity.
