Clinical and molecular effects of oral CCR4 antagonist RPT193 in atopic dermatitis: A Phase 1 study.

Background: RPT193 is an orally administered small molecule antagonist of the human C-C motif chemokine receptor 4 (CCR4) that inhibits the migration and downstream activation of T-helper Type 2 (Th2) cells. We investigated single- and multiple-ascending doses of RPT193 in healthy subjects, and multiple doses of RPT193 in subjects with moderate-to-severe atopic dermatitis (AD).

Methods: This was a first-in-human randomized, placebo-controlled Phase 1a/1b monotherapy study (NCT04271514) to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and CCR4 surface receptor occupancy in eligible healthy subjects and subjects with moderate-to-severe AD.

Laser-Assisted Prostaglandin Analogs in the Treatment of Hypopigmented Scars: A Systematic Review.

Background: Hypopigmented scars are challenging to treat due to a lack of effective treatments and often transient results. Recent reports suggest that prostaglandin analog-induced hyperpigmentation may have favorable dermatological applications.

Objective: Analyze previous studies involving the use of prostaglandin analogs in the treatment of hypopigmented scars.

Intrapatient comparison of atopic dermatitis skin transcriptome shows differences between tape-strips and biopsies.

Background: Our knowledge of etiopathogenesis of atopic dermatitis (AD) is largely derived from skin biopsies, which are associated with pain, scarring and infection. In contrast, tape-stripping is a minimally invasive, nonscarring technique to collect skin samples.

Methods: To construct a global AD skin transcriptomic profile comparing tape-strips to whole-skin biopsies, we performed RNA-seq on tape-strips and biopsies taken from the lesional skin of 20 moderate-to-severe AD patients and the skin of 20 controls.

Applications of Laser Speckle Contrast Imaging Technology in Dermatology.

Laser speckle contrast imaging or laser speckle imaging (LSI) is a noninvasive imaging technology that can detect areas of dynamic perfusion or vascular flow. Thus, LSI has shown increasing diagnostic utility in various pathologies and has been employed for intraoperative, postoperative, and long-term monitoring in many medical specialties. Recently, LSI has gained traction in clinical dermatology because it can be effective in the assessment of pathologies that are associated with increased perfusion and hypervascularity compared with that of normal tissue.

Cross-Sectional Study of Psoriasis, Atopic Dermatitis, Rosacea, and Alopecia Areata Suggests Association With Cardiovascular Diseases.

Background: A growing body of evidence suggests that several inflammatory skin diseases (ISDs) are associated with systemic inflammation and cardiovascular disease (CVDs).

Methods: We used the TriNetX analytics platform to conduct a retrospective, cross-sectional, single-center study in the Mount Sinai Health System network. Cases (all patients ≥18 years of age with a diagnosis of 1 of the 4 ISDs studied) were compared with matched controls (no history of any of these ISDs) to evaluate odds ratios for being diagnosed with CVD.

Scalp biomarkers during dupilumab treatment support Th2 pathway pathogenicity in alopecia areata.

Background: The mechanisms driving alopecia areata (AA) are still unclear, hindering development of targeted therapeutics. Specific Th2 targeting with dupilumab in AA provides a unique opportunity to dissect its pathogenesis and explore the role of Th2 pathway.

Methods: We evaluated changes in scalp biomarkers in AA patients (with and without concomitant atopy) randomized to weekly dupilumab or placebo for 24 weeks, followed by open-label dupilumab for 24 weeks.

Dupilumab Improves Clinical Scores in Children and Adolescents With Moderate to Severe Atopic Dermatitis: A Real-World, Single-Center Study.

Background: Dupilumab has proven safe and effective in children and adolescents with atopic dermatitis (AD) in clinical trials. However, comprehensive real-world studies in the pediatric AD population are still needed.

Objective: To characterize the long-term treatment responses and adverse events of dupilumab-treated children and adolescents with AD during dermatology follow-up assessments.

An Unusual Case of Deep Localized Scleroderma in a Patient with Chronic Kidney Disease.

Localized scleroderma (LS) is a rare fibrosing disorder of skin and underlying tissues. Although it can affect all races, it has a higher prevalence in whites. Deep LS is the least common among seven LS variants, representing less than 5% of cases, and typically affects areas of pressure such as the hips and waist.

The role of MiT/TFE family members in autophagy regulation.

The MiT/TFE family of proteins are important regulators of a number of metabolic processes. One of their most important roles is activating the autophagy pathway in the setting of nutrient deprivation or buildup of toxic metabolites. Their proper and improper functioning in this role has been linked to several types of disease, including cancer and multiple forms of neurodegeneration.

Cartilage Grafting Outcomes in Intermediate and Definitive Cleft Rhinoplasty.

Objective: To compare cartilage grafting outcomes in intermediate versus definitive cleft rhinoplasty.

Design: A retrospective chart review was conducted. The χ and Fisher exact tests were used for statistical analyses.
