Zinc deficiency in bullous pemphigoid: predisposing factors, skin fragility, and renal function impact

This study investigated serum zinc levels in patients with bullous pemphigoid and identified a high prevalence of zinc deficiency, particularly among those with low body mass index, chronic kidney disease, and hypertension. Zinc supplementation was associated with improved renal function and reduced skin fragility, highlighting its potential therapeutic role in managing bullous pemphigoid.
