Abstract:
Mozambique has no study about the prevalence and
the clinical impact of occult B infection and has the
eighth highest HIV prevalence in the world. HIV is one of the
most recognized risk factor for occult hepatitis B. The aim of
this study was to investigate the frequency and clinical and
laboratory characteristics of OBI in ART naive HIV infected
patients. We conducted a cross-sectional study in two health
facilities within Maputo city, between June and October 2012.
A questionnaire was used to obtain demographics and clinical
data. Serological studies was done in blood samples, such as,
HBV surface antigen (HBsAg), antibodies against HBV surface
antigen (anti-HBs) and antibodies against core antigen (anti-
HBc), as well as a quantification of HBV DNA using real time
PCR.
We find that from the 518 ART-naive HIV-positive subjects,
90.9% (471/518) were HBsAg negative. Among HBsAg
negative, 45.2% (213/471) had isolated anti-HBc antibodies,
and the frequency of OBI among patients with anti-HBc alone
was 8.3% (17/206) (fig 1). A total of 11.8% of patients with OBI
presented elevated HBV DNA level. Frequency of individuals
with APRI score > 2 and FIB-4 score > 3.25 was higher in
patients with OBI as compared not exposed, immune and
anti-HBc alone patients. OBI was not correlated either with
CD4+ T cells count or transaminases levels.
We conclude that OBI is prevalent among HIV patients in
Mozambique, and that the screen testes are not sufficient to
diagnose this patient.
