Seroprevalence of Cytomegalovirus, Epstein-barr Virus and Herpes Simplex Viruses in Children Born HIV Positive at the Yaounde University Teaching Hospital, Cameroon

Abstract

Background: Cameroon is a country located in sub-Saharan Africa, which is an area endemic to herpesviridae family, there is very little data on the herpes virus infections epidemiology, especially associated with HIV infection. Aims: The aim of our study was to determine the seroprevalence of four herpes viruses that are cytomegalovirus (CMV), Epstein-Barr virus (EBV), Herpes Simplex virus 1 (HSV-1) and 2 (HSV-2) in HIV-positive patients in Yaoundé University Teaching Hospital. Methodology: the study was prospective cross-sectional and took place at Yaounde University Teaching Hospital and Department of Microbiology, Faculty of Sciences, University of Yaounde I, between November 2020 and April 2021. We included consecutively 74 on children living with HIV born HIV positive, on antiretroviral treatment (23 men, 51 women; age range 3-19 years), and whose medical file was complete and available within the ATC. IgG/IgM antibodies against HSV-1, HSV-2, CMV, and IgM against EBV were qualitatively determined by Rapid Diagnostic Tests, for the detection of these pathogens. The statistical analysis was done using IBM SPSS version 22.0, the Fisher exact and the Khi-sqaure tests to compare qualitative variables between groups, while on the other hand, we used the Mann-Whitney test to compare quantitative variables. All P values below 0.05 were considered significant. Results: A total of 74 participants were enrolled in the study with a female predominance of 68.92% (n=51/74). The average age of our serie was 9.05±5.09 years, and a majority of participants was under 10 years old (56.76%, n=42/74). HSV-1, HSV-2, EBV and CMV Seroprevalences were 93.24%, 93.24%, 22.97% and 12.2% respectively. Other parameters such as sex, age, stage of disease, smoking and alcohol consumption were significantly associated with the seropositivity of these herpesviridae. Conclusion: Despite the absence for most of the clinical manifestations related to HSV-1 and HSV-2, it was strong to note a high circulation of those virus in HIV infected patients, mainly in bi and tri co-infections.
