Abstract
AbstractBackgroundSome studies emphasise the relationship between the herpes simplex virus (HSV) and pemphigus. Although the possible role of HSV in the pathogenesis of pemphigus and the severity of the disease is obscure, we aimed to evaluate the presence of herpes simplex viruses (HSV 1/2) in the oral lesions of patients with pemphigus vulgaris and also assess its association with disease severity and types of lesions.MethodsA retrospective study was conducted on collected data in the form of collecting paraffin blocks, slides, and relevant pathology reports and referring to patients' medical records. A questionnaire containing details on the degree of skin, scalp, and mucosal involvement (Pemphigus Disease Area Index (PDAI)) was fulfiled. The immunoassay result was also collected to check the anti‐desmoglein 3 and 1 antibodies (using ELISA technique).ResultsIn this study, 52 patients of pemphigus vulgaris with oral lesions (case) and 52 patients with oral lesions not related to the disease (control) were evaluated. HSV1 was detected in 13.5% of oral pemphigus lesions and 1.9% of the control group (p = 0.0598). There were no positive cases of HSV2 in either group. There was no significant association between the positivity of HSV1 and the site of lesions (p = 1.00) or disease severity (p = 0.28). However, we found a strong correlation between the PDAI disease severity score with the titre of the AntiDsg3 antibody (r = 0.487,p = 0.001) and AntiDsg1 antibody (r = 0.309,p = 0.026).ConclusionThis study demonstrated a significant prevalence of HSV1 in oral pemphigus lesions, and acyclovir therapy may play a significant role in managing these patients. However, HSV's role in thepathogenesisof pemphigus vulgaris cannot be clearly determined.
