Background: Management of moderate-to-severe atopic dermatitis (AD) needs long-term therapy. Stapokibart is a humanized monoclonal antibody targeting interleukin-4 receptor α subunit (IL-4Rα), a shared receptor for IL-4 and IL-13 which are key pathogenic drivers of AD. In a pivotal phase 3 trial (NCT05265923), significant higher proportions of adult AD patients receiving stapokibart than placebo achieved ≥75% improvement from baseline in Eczema Area and Severity Index (EASI-75; 66.

Background: Stapokibart/CM310, a humanized monoclonal antibody targeting the interleukin-4 receptor α chain, has shown promising treatment benefits in patients with moderate-to-severe atopic dermatitis in previous phase II clinical trials.

Objective: We aimed to evaluate the long-term efficacy and safety of stapokibart in adults with moderate-to-severe atopic dermatitis.

Methods: Enrolled patients who previously completed parent trials of stapokibart received a subcutaneous stapokibart 600-mg loading dose, then 300 mg every 2 weeks up to 52 weeks.

  • - FMX101 4% is a topical foam formulation of minocycline approved for treating moderate-to-severe acne vulgaris, and a study was conducted to evaluate its effectiveness and safety among Chinese patients.
  • - In a phase 3 trial involving 372 subjects, results showed that FMX101 4% led to a significant reduction in inflammation lesion count (ILC) and noninflammatory lesion count (nILC), along with a higher treatment success rate compared to a control foam after 12 weeks.
  • - The treatment was generally safe and well-tolerated, with mostly mild-to-moderate side effects and no serious adverse events linked to the treatment.

Neurosyphilis is a serious global health issue and a big challenge in developing countries, related risk factors should be taken seriously. Although there are a certain number of studies describing the clinical and laboratory features and risk factors for symptomatic neurosyphilis (SNS), but some risk factors are still controversial. The aim of this research is to investigate the association between asymptomatic neurosyphilis (ANS) and symptomatic neurosyphilis (SNS) and identify risk factors for SNS.

The function and survival of melanocytes is regulated by an elaborate network of paracrine factors synthesized mainly by epidermal keratinocytes (KCs). KCs and melanocytes respond to UV exposure by eliciting a tanning response. However, how KCs and melanocytes interact in the absence of UV exposure is unknown.

  • Patients with psoriasis may see worsened symptoms after a COVID-19 infection, and this study aimed to explore this issue in those on three biologics: adalimumab, secukinumab, and ixekizumab.
  • A prospective study with 209 patients showed that while psoriasis severity can worsen after COVID-19, those treated with biologics had a lower chance of exacerbation, particularly those on ixekizumab, with statistically significant results.
  • The findings suggest that continuing biologic treatment during COVID-19 may offer protective benefits for psoriatic patients, highlighting the importance of maintaining therapy amid infection risks.*

Melanocytes, which originate from the neuroectoderm, are specialized cells responsible for producing pigments and possessing a dendritic morphology. These cells migrate to the epidermis and follicles, contributing to skin and hair pigmentation during embryonic development. The remarkable self-renewal capacity of melanocytes enables them to effectively restore hair and skin pigmentation.

Article Synopsis
  • - Atopic dermatitis (AD) is a common inflammatory skin disease linked to issues like skin barrier dysfunction and immune system dysregulation, with STAT3 playing a key role in skin cell function.
  • - Researchers created a mouse model with specific loss of STAT3 in skin cells, which showed worsened AD-like symptoms after exposure to a skin irritant, indicating a negative impact on skin health and microbiome composition.
  • - The study found that mice with STAT3 deficiency exhibited more type-2 inflammatory cells and increased levels of TSLP, a protein that attracts immune cells, suggesting that targeting TSLP could help reduce skin inflammation in AD.

Article Synopsis
  • Psoriasis involves excessive skin cell growth and immune cell infiltration, with the exact causes remaining uncertain.
  • Researchers found that glycyl-tRNA synthetase (GARS), typically involved in protein synthesis, is overexpressed in the skin and blood of psoriasis patients, promoting skin inflammation and abnormal growth when present in high levels.
  • The study suggests that targeting GARS could be a potential new treatment strategy for psoriasis, as reducing its expression showed improvements in inflammation and skin condition in laboratory models.

Background: Atopic dermatitis (AD) affects approximately 10% of adults worldwide. CM310 is a humanized monoclonal antibody targeting interleukin-4 receptor alpha that blocks interleukin-4 and interleukin-13 signaling. This trial aimed to evaluate the efficacy and safety of CM310 in Chinese adults with moderate-to-severe AD.

The skin is the outermost barrier that separates the human body from the external environment. In psoriasis, immune cells reside within or infiltrate the epidermis to form the epidermal (epithelial) immunological microenvironment (EIME) and engage in complex interactions with keratinocytes, nerves, and microbiota. The proposed hypothesis is that psoriasis is a chronic inflammatory disease mainly mediated by a specific inflammatory environment composed of keratinocyte-neuro-immune cell units (KNICUs).

Objectives: To describe the demographics and phenotypes of malignancies-associated dermatomyositis (MADM) in east China and pinpoint potential factors indicative of malignancies in patients with dermatomyositis and establish a predictive model.

Methods: We retrospectively analyzed clinical data from 134 patients with adult-onset dermatomyositis hospitalized between January 2019 and May 2022 in one comprehensive hospital. Clinical data including disease course, initial symptoms and signs, and demographic information were retrieved from the Electronic Medical Records System.

Background: The hyperproliferation featured with upregulated glycolysis is a hallmark of psoriasis. However, molecular difference of keratinocyte glycolysis amongst varied pathologic states in psoriasis remain elusive.

Objectives: To characterize glycolysis status of psoriatic skin and assess the potential of glycolysis score for therapeutic decision.

  • ALA-PDT is an effective alternative treatment for severe acne vulgaris, recommended by clinical guidelines, but lacks detailed specific protocols.
  • A consensus among dermatologists and PDT experts led to evidence-based recommendations for using ALA-PDT in acne treatment, targeting its major causes and suitable for patients who can't take antibiotics or isotretinoin.
  • The guidelines focus on various PDT procedures, emphasizing M-PDT for moderate to severe acne due to its lower pain and improved efficiency, while also addressing management of adverse effects.

Proinflammatory cytokines, such as IL-1β, are important mediators of psoriasis. UBE2L3, an E2 enzyme, is thought to be an indirect target of IL-1β secretion by binding to ubiquitin ligases such as TRIM21. However, its role in psoriasis remains unknown.

Background: The Isoleucyl-tRNA synthetase (IARS) catalyzes isoleucine to the corresponding tRNA, maintaining the accuracy of gene translation. Its role in psoriasis has been not investigated so far. In this study, we aimed to investigate the mechanisms underlying the efficacy of IARS inhibitor, mupirocin, treatment for psoriasis.
