Resumo
The hepatitis B virus infection (HBV) and diabetes mellitus type II represent serious
public health problems and, the synergism between these two diseases, can affect the
prognosis of the patients with increased risk of developing chronic liver disease,
cirrhosis and hepatocellular carcinoma. The aims of the present study were to
investigate the HBV occult infection and to evaluate the vaccine response in patients
with diabetes mellitus type II, in Goiânia-Goiás. This study is part of the research
"Investigation of the serological, epidemiological and molecular profile of the
hepatitis B virus infection in patients with diabetes mellitus type 2 in Goiânia-Goiás"
which was developed in five public health units Goiânia. After serologic screening of
the population (n = 605), 108 anti-HBc positive patients/HBsAg negative were
selected for the HBV-DNA research. For this, after extraction of viral genome, a
semi-nested PCR was performed with primers complementary to region pre-S/S of
HBV. Among the patients recruited in the units of the Family Health Program (N =
215) those susceptible to HBV infection (N = 172) were selected and invited to
participate of the cohort about vacinal response. Thus, 128, 99 and 87 individuals
agreed to receive the first, second, and third doses of recombinant vaccine Butang®,
respectively. The subjects who received three doses of the vaccine and who agreed to
participate in a new blood collection (N = 69) were evaluated for the quantitative
detection of anti-HBs marker by enzyme-linked immunosorbent assay microparticle
(MEIA) using the AxSYM system automation and AxSYM kits AUSAB (Brazil
Abbot Laboratories). It was not found occult HBV infection in diabetic patients in
Goiânia- Goiás, which is similar to that found in other population groups in Brazil. In
relation to the vaccine response, of the 69 samples analyzed, was observed that
53.6% of patients were able to respond to vaccination, and the geometric mean of
anti-HBs titres was 13.76 mIU/mL. The seroprotection rate found in diabetic patients
in Goiânia- GO was considered low compared to the healthy adult population. Thus,
the data obtained in this study may help in the planning of specific prevention actions
of hepatitis B in a population that usually have comorbidities.
