RESUMO
BACKGROUND: Acne vulgaris is among the most common dermatologic diagnoses observed, including skin color (SOC) populations. This project sought to help clarify the existing published data and provide consensus statements on acne presentation, prevention, treatment, and maintenance in SOC populations to help improve patient outcomes. METHODS: Six SOC dermatologists convened for a virtual meeting and used a modified Delphi process to address: 1) Are there racial/ethnic differences in the clinical presentation and sequela of acne? 2) Are there racial/ethnic differences in the therapeutic endpoint of acne treatment and patient expectations? 3) Is there a need for specialized approaches to therapeutic options and skincare in acne patients with SOC? The results of a literature review and the outcome of discussions, coupled with the panel's expert opinion and experience, are intended for health care providers caring for acne patients and clinician-researchers. RESULTS: Racial/ethnic differences in the clinical presentation, sequelae, and desired treatment outcomes for acne have been reported. Notwithstanding limitations in the number, size, and methodologies of studies to date, the available data suggest that strategies that improve outcomes in acne patients with SOC include: Early initiation and maintenance of treatment regimens and careful consideration of tolerability of active ingredients, vehicles, and dosing. Using pH-balanced, non-irritating cleansers and non-comedogenic ceramides containing moisturizers help minimize irritation or dryness. CONCLUSIONS: There a need for specialized approaches to therapeutic options and skincare in acne patients with SOC. OTC skincare products are recommended before and during prescription therapy and as part of a maintenance regimen.

Airway mucus hypersecretion contributes to the morbidity and mortality in patients with chronic inflammatory lung diseases. Reducing mucus production is crucial for improving patients' quality of life. The transcription factor SAM-pointed domain-containing Ets-like factor (SPDEF) plays a critical role in the regulation of mucus production and, therefore, represents a potential therapeutic target. This study aims to reduce lung epithelial mucus production by targeted silencing SPDEF using the novel strategy, epigenetic editing. Zinc fingers and CRISPR/dCas platforms were engineered to target repressors (KRAB, DNA methyltransferases, histone methyltransferases) to the SPDEF promoter. All constructs were able to effectively suppress both SPDEF mRNA and protein expression, which was accompanied by inhibition of downstream mucus-related genes [anterior gradient 2 (AGR2), mucin 5AC (MUC5AC)]. For the histone methyltransferase G9A, and not its mutant or other effectors, the obtained silencing was mitotically stable. These results indicate efficient SPDEF silencing and downregulation of mucus-related gene expression by epigenetic editing, in human lung epithelial cells. This opens avenues for epigenetic editing as a novel therapeutic strategy to induce long-lasting mucus inhibition.
