Candida Species Prevalence Profile in HIV Seropositive Patients from a Major Tertiary Care Hospital in New Delhi, India.

Abstract

Candida is a common opportunistic pathogen during the course of human immunodeficiency virus (HIV) disease progression. Changes in the clinical severity of candidiasis and the Candida species prevalence profile may be a reflection of immunological changes in HIV positive patients. The aim of this study was to document the changing pattern of Candida species prevalence profile in HIV seropositive patients from a tertiary care hospital in North India. One hundred and twenty HIV seropositive subjects were recruited for Candida microbial screening. Clinical specimens including blood, oral swabs, expectorated or induced sputum/bronchoalveolar lavage specimens, and urine were collected depending on the patient's symptoms. A total of 128 Candida isolates were obtained from 88 cases and 7 different Candida species were identified. C. albicans (50%) was the most common species isolated followed by C. glabrata (17%) and C. dubliniensis (12.5%). Other species isolated were C. parapsilosis (7.8%), C. krusei, C. tropicalis (4.6% each), and C. kefyr (3%). Strong clinical suspicion along with optimal sampling of an accurate diagnosis of Candida species involved would go a long way in decreasing the morbidity associated with non-albicans Candida species.
