Comparison of Plasma Zinc Levels Among HIV positive and HIV negative Subjects Infected with Condyloma Acuminata

Background: Condyloma acuminata is a type of human papilloma virus (HPV) infection in the anogenital area and often associated with immunosuppressive conditions, such as human immunodeficiency virus (HIV). Low plasma zinc levels could cause alteration of cellular immunity, leading to reduction of interleukin-2 (IL-2) and interferon-? (IFN-?), cytokines required for inhibition of HPV replication. Moreover, low plasma zinc levels could cause disruption of apoptotic regulation, results in the unimpeded proliferation of epithelial cells infected with HPV. This study aimed to compare the mean plasma zinc levels in condyloma acuminata patients with HIV and without HIV infection. Methods: This study used a cross-sectional method, involving 27 condyloma acuminata patients without HIV infection and 18 patients with HIV infection, who agreed to enroll and signed the informed consent. This study was conducted in the dermatology and venereology outpatient clinic in Sanglah Hospital and Kerti Praja Foundation, Denpasar. Bivariate analysis of the characteristics, age, sex orientation, location of lesion, clinical form of lesion, type of cases, duration of condyloma acuminata, age of the first sexual contact, comorbidity, treatment history, and mean plasma zinc level of condyloma acuminata patients with HIV and without HIV infection. The CD4+ cell count and history of ARV treatment were also obtained form patients with HIV infection. Results: A total of 45 subjects were diagnosed with condyloma acuminata, consisted of 27 subjects with condyloma acuminata without HIV infection and 18 subjects with HIV infection, showing average age of 32.04 ± 10.414. Mean plasma zinc levels in condyloma acuminata patients with HIV infection was significantly lower than subjects without HIV infection, and the difference in mean plasma zinc levels was 7.31 µg/dL (95% CI 2.25 - 12.37, p <0.05). Conclusions: The mean plasma zinc levels in condyloma acuminata patients with HIV was significantly lower than those of without HIV infection.
