ABSTRACT
Background: Herpes simplex virus type 2 [HSV-2] is a common infection in human immunodeficiency virus [HIV] patients and may accelerate HIV progression by rising HIV viral load and decreasing CD4 count. However, the available data regarding the influence of HSV-2 seropositivity on HIV progression in HIV individuals are inconclusive. Therefore, we aimed to determine HSV-2 seroprevalence in naive HIV patients and normal controls and also investigate the relation of HIV viral load and CD4 count with HSV-2 seropositivity. Subsequently, we investigated the association of HSV-2 serostatus with changing in CD4 count and HIV viral load in our subjects, after one year follow-up
Methods: In this study, 116 naive HIV patients and 85 healthy controls from Tehran, Iran were enrolled. HSV-2 IgG antibody was detected by ELISA. CD4 count was determined by flowcytometry, and serum HIV RNA copy numbers were determined using real-time PCR
Results: The prevalence of HSV-2 IgG was 18.1% in naive HIV patients and 0% in the control group [P = 0.000]. HSV-2 seroconversion was observed in 2.43% of HIV patients after one year. There was no significant difference regarding HSV-2 serostatus with CD4 count and HIV RNA viral load in our study cohort at baseline and after one year
Conclusion: Our results revealed that the prevalence and incidence of HSV-2 infection are low in our HIV cases, and it is negligible in the control group. However, it seems that HIV/HSV2 co-infection has no role on HIV infection acceleration
