Background
In human immunodeficiency virus (HIV) and hepatitis B virus (HBV) co-infected patients from sub-Saharan Africa with hepatitis B e antigen (HBeAg)-negative status, data are limited on the evolution of HBV activity when antiretroviral treatment (ART) is absent.
Methods
A total of 43 HBeAg-negative co-infected patients not indicated for ART (per concomitant World Health Organization recommendations) were followed during participation in a randomized controlled trial in Côte d’Ivoire. Chronic HBeAg-negative phases were classified at yearly visits and defined as ‘infection’ (HBV DNA ≤10 000 copies/mL and normal alanine aminotransferase [ALT]) or ‘hepatitis’ (HBV DNA >10 000 copies/mL and/or above normal ALT). Dispersion in HBV DNA and ALT levels during follow-up was assessed using interquartile range (IQR) regression.
Results
During a median 25 months (IQR 19–31), 17 (40%) patients consistently had ‘infection’, 5 (12%) consistently had ‘hepatitis’ and 21 (48%) fluctuated between phases. Wider dispersion in HBV DNA over time was associated with higher baseline HIV RNA (p=0.02) and higher baseline HBV DNA levels (p=0.008), while wider dispersion in ALT was associated with higher baseline HIV RNA (p4.0 log10 IU/mL (p=0.02).
Conclusions
HBV activity is common with HBeAg-negative status, whose variation is partly linked to HIV replication. Fluctuations in disease phase make it difficult to assess the risk of morbidity and mortality after ART initiation. |
