Letter Case ReportsUse of low-dose naltrexone in the treatment of severe Hailey-Hailey disease: One case report.
Hailey-Hailey disease (HHD) or chronic benign familial pemphigus is an autosomal dominant genodermatosis with complete penetrance characterized by painful vesicles, erosions, and macerated intertriginous skin. We present a 66-year-old woman with a personal 35-year history of pruritic recurrent vesicles and erosions in both axillae and inguinal folds. HHD was confirmed by cutaneous biopsy. ⋯ Paradoxically, at low doses, the partial binding to those receptors leads to a homeostatic increase of opioid receptors and an upregulation of endogenous opioids. Low-dose naltrexone (LDN) may also exert an anti-inflammatory action through its antagonist effect on toll-like receptor 4 found on macrophages. We consider that LDN is an effective and safe alternative for the HHD, representing an important progress in the management of this disease with limited therapeutic options.
