Nine cases of refractory bullous pemphigoid treated with dupilumab and literature review.

Background And Aims: Bullous pemphigoid is an autoimmune blistering disease that affects the elderly mostly. First-line treatment of systemic corticosteroids may cause significant adverse effects, especially in patients with multiple co-morbidities. Dupilumab shows certain effectiveness in treating BP.

Systematic review and network meta-analysis of different types of emollient for the prevention of atopic dermatitis in infants.

Prophylactic application of emollients has been an effective strategy against infant atopic dermatitis (AD); however, the difference of different emollients is unknown. We performed this network meta-analysis to compare different emollients in preventing infant AD. A systematic search was performed in PubMed, EMBASE and Cochrane library to identify relevant studies from their inception through 28 February, 2022.

UVB-induced SFRP1 methylation potentiates skin damage by promoting cell apoptosis and DNA damage.

In response to the accumulation of genetic mutations and cellular changes, ultraviolet radiation B (UVB) skin lesions undergo dysplasia and transform into a cutaneous squamous cell carcinoma (CSCC). Consistent with our previous findings that secreted frizzled-related protein 1 (SFRP1), a member of the SFRP gene family, was downregulated in human CSCC tissue samples, we found a significant downregulation of SFRP1 in HaCaT, A431, and SCL-1 cells after UVB irradiation. DNA methyltransferase 1 (DNMT1) was significantly increased in CSCC tissues as well as UVB-exposed A431 and SCL-1 cells.
