Study of clinical profile of herpes zoster in human immunodeficiency virus positive and negative patients at a rural-based tertiary care center, Gujarat

BACKGROUND: Herpes zoster usually presents with typically grouped vesicles on erythematous base involving single dermatome with self-limiting nature in immunocompetent individuals while it may present in extensive form involving multiple dermatomes involvement or disseminated form in immunocompromised, especially in human immunodeficiency virus (HIV). AIMS AND OBJECTIVES: The aim of this study was to study the prevalence of HIV in patients of herpes zoster, to compare the clinical presentation of herpes zoster in HIV-infected and noninfected patient. MATERIALS AND METHODS: The study was carried out in the Department of Dermatology in a Teaching Institute of Gujarat, from June 2008 to May 2014 after ethical clearance. The study population included all the patients with a clinical diagnosis of herpes zoster. All the patients were investigated for HIV infection after written consent. RESULTS: Out of total 688 patients of herpes zoster, 35 (5.1%) were HIV-positive, 26 (74.3%) were males and 9 (25.7%) were females. Among HIV-positive patients, 29 (82.85%) patients had localized dermatomal involvement, 4 (11.42%) patients had multiple dermatomal involvement, and only 2 (5.71%) had disseminated zoster while among HIV-negative, 636 (97.40%) had localized dermatomal involvement, 14 (2.14%) patients had multiple dermatomal involvement, and 3 (0.45%) had disseminated zoster. Cervical dermatome was most commonly involved dermatome in patients of HIV. CONCLUSION: Disseminated and multiple dermatomal involvement was more commonly involved among HIV-positive patients when compared to HIV-negative patients.
