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.
