Sero-Prevalence of Parvovirus B 19 Infection Among HIV Positive Patients Attending Tertiary Care Hospital in Central India
Objective: The aim of this study was to assess sero-prevelance of Parvovirus B19 among HIV positive patients attending tertiary care hospital from central India.
Methods: This was a hospital based cross sectional study conducted from June 2014 to September 2014. The study population includes 100 HIV positive patients attending ART Clinic with signs and symptoms suggestive of anemia and hemoglobin <10g/dL were included. Blood samples were collected and the sera obtained after centrifugation of clotted samples were stored at -20ºC. Enzyme-linked immunesorbent assay was used to detect IgG and IgM antibodies. CD4+ count estimation of blood samples was done by Flow cytometry. The demographic information’s were collected from patients using structured questionnaire prior to sample collection. Institutional Ethical committee approval has been taken prior to conduct this study. The consent to collect the study data was also obtained from the patients. The data were analyzed using statistical software Epi Info 7.
Results: The mean age of study subjects was 37.44±9.80 years and 55 (55%) were males and 45 (45%) were females. IgG and IgM antibody test showed, 6 (6%) and 11 (11%) cases were positive for anti-parvovirus IgM and IgG antibodies respectively. Thus, 17(17%) patients were positive for anti-parvovirus IgM or IgG antibodies. Among the 17 positive cases, IgG was more prevalent. There were 14 cases (14%) had Hb % in the range of 5.0- 6.9g/dL, 6 (42.8%) of these were seropositive for anti-parvovirus antibody (IgM or IgG) and a single case with Hb% less than 5 g/dL. There was no statistically significant correlation between CD4 count and sero-positivity.
Conclusion: The prevalence of anti-PVB19 IgM and IgG antibodies among HIV-infected patients was 6% and 11% respectively.
