Background: Preliminary observation in clinical practice showed that subjective neurocognitive complaints are relatively common in bullous pemphigoid (BP) patients. Yet, little has been done to investigate the neurocognitive status in BP.

Methods: This is a multicenter observational case-control study comprised of 61 BP patients and 65 matched control subjects from 3 medical centers in China from 2014 to 2019. To evaluate the cognitive function between BP patients and matched controls, all the subjects finished the mini-mental state examination (MMSE) and montreal cognitive assessment (MoCA).

Results: The overall scores were significantly lower in BP than in controls (P<0.001). The percentage of patients screened positive for cognitive impairment in the BP group was significantly higher than in the control group (P<0.001, P<0.001). On multivariate analysis, BP was associated with increased odds of cognitive impairment by MMSE and MoCA (P=0.017, P=0.007).

Conclusions: BP patients had decreased cognitive abilities and were at a higher risk of cognitive impairment. The evaluation of cognitive impairment may be warranted for BP patients in clinical practice for early diagnosis and therapy of dementia.

Objectives: This study aimed to evaluate the efficacy of low-dose interleukin (IL-2) treatment for bullous pemphigoid (BP) caused by anti-programmed cell death protein 1/ligand 1 (PD-1/PD-L1) inhibitors.

Methods: Low-dose IL-2 treatment was standardized for BP. The Bullous Pemphigoid Disease Area Index (BPDAI), 5D-Itch Scale (5D-IS), and Dermatology Life Quality Index (DLQI) were recorded before and after treatment, and hexachromatic lymphocytes, regulatory T cells (Treg cells), and cytokines were measured.

Bullous pemphigoid (BP) is the most prevalent autoimmune subepidermal blistering disease of the skin and mucous membranes. This disease typically affects the elderly and manifests with pruritus and localized or, most commonly, generalized bullous lesions. Numerous studies have established the association between BP and oral antidiabetic agents, particularly dipeptidyl peptidase 4 (DPP4) inhibitors, diuretics, and certain antibiotics, notably levofloxacin and cephalexin.

Bullous pemphigoid (BP) is a rare autoimmune blistering disease characterised by autoantibodies against basal skin membrane antigens. Although the condition's aetiology remains unclear, recent cases have raised suspicions of an association with immunisation. In this study, we present a case of BP onset in a four-month-old infant following routine vaccination.

Article Synopsis
  • - Macrophages are key immune cells that play diverse roles in the body, especially in the skin, which is the largest immune organ and is crucial for studying various skin-related conditions.
  • - This review focuses on recent findings about macrophages in inflammatory skin diseases like atopic dermatitis and psoriasis, as well as skin tumors such as melanoma and cutaneous T-cell lymphoma.
  • - The goal is to enhance understanding of how macrophages contribute to these diseases and explore potential new treatments targeting them.

We present the case of a 36-year-old paraplegic woman with a history of spinal cord injury who developed a generalized blistering rash, later diagnosed as bullous pemphigoid (BP). During her hospitalization, she was treated with prednisone and rituximab infusions, transitioning to maintenance therapy with topical steroids, doxycycline, and nicotinamide. A year later, she presented with concerns about a BP flare on her feet.
