Enteric viruses associated with HIV infection in Tanzanian children with chronic diarrhea

Area of Science:

• Pediatric Infectious Diseases
• Viral Gastroenteritis
• HIV/AIDS Research

Background:

• Chronic diarrhea is a significant health issue in children, particularly in resource-limited settings.
• Human immunodeficiency virus (HIV) infection can exacerbate gastrointestinal problems, including chronic diarrhea.
• Identifying specific viral etiologies is crucial for effective management and prevention strategies.

Purpose of the Study:

• To investigate the association between specific enteric viruses and HIV infection in children experiencing chronic diarrhea.
• To compare viral prevalence in HIV-infected children with chronic diarrhea versus HIV-uninfected children and controls.

Main Methods:

• A cross-sectional survey was conducted at a major national teaching hospital in Dar es Salaam, Tanzania.
• Enteric viruses in fecal specimens were identified using electron microscopy (EM).
• The study included HIV-infected children, HIV-uninfected children with chronic diarrhea, and children without diarrhea, aged 15 months to 5 years.

Main Results:

• Small round structured viruses (SRSV) were found to be more frequent in HIV-infected children with chronic diarrhea compared to HIV-uninfected children (prevalence ratio = 6.09).
• Rotavirus and coronavirus-like particles (CVLP) did not show a significant association with HIV infection status in children with chronic diarrhea.
• The findings suggest a potential link between SRSV and HIV-related chronic diarrhea in this pediatric cohort.

Conclusions:

• Small round structured viruses (SRSV) may be associated with chronic diarrhea in HIV-infected children in Tanzania.
• The study highlights the need for larger, confirmatory research to validate these findings.
• Understanding viral co-infections in HIV-positive children is essential for improving clinical outcomes.
