Prevalence and risk factors of cytomegalovirus infection among HIV-infected and HIV-exposed uninfected infants in Nigeria.

INTRODUCTION: Cytomegalovirus (CMV) co-infection increases morbidity and mortality in human immunodeficiency virus (HIV) disease. There has been no study on CMV infection and its risk factors among Nigerian HIV-infected and/or HIV-exposed uninfected infants. METHODOLOGY: This was a cross-sectional cohort study at the Federal Medical Center, Makurdi, between January 2012 and March 2013. Acute CMV infection among consecutive three-month- old HIV-infected and HIV-exposed uninfected infants was determined using the enzyme-linked immunosorbent assay of the CMV immunoglobulin M (IgM). The relationship between acute CMV infections in the infants and the potential risk factors was tested using logistic regression analyses. RESULTS: The prevalence of acute CMV infection was 41.4% (91/220), including 12.1% (11/91) and 87.9% (80/91) among the HIV-infected and the HIV-exposed uninfected infants, respectively. In multivariate logistic regression analyses, oropharyngeal candidiasis in the infants, HIV co-infection in the infants, maternal mastitis during breastfeeding, and the absence of maternal chronic CMV infections significantly increased the risk of acute CMV in the young infants. CONCLUSIONS: In our setting, concerted efforts to prevent and/or promptly treat oropharyngeal candidiasis and mastitis during breastfeeding may reduce the burden of CMV among HIV-infected and HIV-exposed uninfected infants. Public enlightenment on the mode of CMV transmission and its prevention is also important.

Effects of leisure activities and psychosocial support on medication adherence and clinic attendance among children on antiretroviral therapy.

BACKGROUND: Optimal adherence to antiretroviral therapy (ART) and retention-in-care are essential in HIV management. Through a Kiddies' Club (KC), the study aimed at assessing the impact of social leisures and psychosocial support on ART adherence and clinic attendance in a pediatric ART program. METHODS: This was a descriptive, longitudinal study, conducted at the Federal Medical Centre, Makurdi, Nigeria, from June 2011 to June 2012. It included 33 ART-experienced children and their caregivers. The study was supplemented with a qualitative focused group discussion, involving 12 discussants. ART adherence, clinic attendance, and clinical and immunoviralogical responses of the children to ART were noted at 6 months and at 12 months of follow-up. RESULTS: The children comprised 17 males and 16 females, with a median age of 5 years. Financial constraint was the most common reason given for losses to follow-up in quantitative (32/33, 96.9%) and qualitative (12/12, 100.0%) assessments. But, unavailability of means of transportation may still override the benefit that financial assistance can provide, as reported in the qualitative study. The baseline mean hemoglobin level (8.50 g/dL), median CD4 count (187.00 cells/mm(3)); median weight for height z-score (-0.395), and the median body mass index (15.40) increased significantly to respective values of 10.03 g/dL, 1,030.00 cells/mm(3), -0.090, and 18.50, at 6 months (P-values: 0.000), and 10.47 g/dL, 1,203.00 cells/mm(3), 0.420, and 19.20, at 12 months (P-values: 0.000). The baseline median viral load (45,678.00 copies/mL) also decreased significantly, to 200.00 copies/mL at 6 months and at 12 months (P-values: 0.000). There was no attrition from death or loss to follow-up, and adherence to ART was 100%, at 6 months and at 12 months of follow-up. CONCLUSION: Through the KC, children were retained in care, with excellent adherence to ART, and good clinical and immunoviralogical responses to ART, even after being previously lost to follow-up.
