Background:
Bullous pemphigoid (BP) is a chronic autoimmune blistering disease prevalent in the elderly, often accompanied by renal comorbidities. Immune dysregulation can lead to secondary BP and increased mortality rates in those already diagnosed.
Methods:
A literature review identified studies on the association between kidney disease and other comorbidities with BP. Pooled effect estimates were analyzed utilizing a random-effects model.
Objective:
To assess comorbidity risks with BP and determine mortality risk among BP patients with comorbidities.
Results:
Analysis included 45,323 BP patients from 49 studies. Kidney diseases were significantly linked to higher BP incidence (subdistribution hazard ratio 1.51, 95% CI: 1.10-2.07) and increased mortality (hazard ratio 1.62, 95% CI: 1.13-2.32). Cerebrovascular diseases, dementia, and diabetes also showed significant associations with both increased BP incidence and mortality (P < .05). However, cardiovascular diseases and malignancy were only associated with increased mortality among BP patients (P < .001) without affecting BP incidence (P = .785 and P = .792, respectively).
Limitation:
The study comprises mostly case-control, prospective, and retrospective observational studies, alongside data heterogeneity.
Conclusion:
This study reveals the association of several chronic conditions, including kidney diseases, with BP, contributing to elevated mortality rates. The findings emphasize the importance of management targeting both BP and associated comorbidities to improve patient outcomes.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
