Abstract
In Brazil, few studies on the molecular aspects of hepatitis B virus (HBV)
infection have been conducted in the interior regions of Sao Paulo State. This
study aimed to identify HBV genotypes and evaluate strains with resistance
mutations for nucleoside analogues in the Administrative Region (AR) of the
municipality of Sao Jose do Rio Preto. We performed nested PCRs of 127 samples
from the Health Care Services of the AR to amplify, sequence and analyze
fragments of the HBV DNA, in order to identify genotypes and resistance
mutations. The HBV S/Pol regions of 126 samples were successfully amplified and
sequenced. Five different genotypes were found, and the main ones were A, D and
F; a greater number of samples contained the subgenotypes A1 (n = 51; 40.5%), D3
(n = 36; 28.6%), A2 (n = 14; 11.1%) and F2a (n = 9; 7.1%). Resistance mutations
(rtM204V/I/S) associated or not with compensatory mutations (rtL180M, rtV173L)
were identified in 13.9% (5/36) of patients undergoing viral treatment and 1.1%
(1/90) of naïve patients. The diversity of genotypes/subgenotypes found is
probably due to the intense migration occurring in the region. These data can
complement epidemiological and clinical surveillance, and can be used for a more
effective management of chronic HBV patients.

Abstract
Hepatitis B (HBV) and delta (HDV) viruses are endemic in the Amazon region, but vaccine coverage against HBV is still limited. People who use illicit drugs (PWUDs) represent a high-risk group due to common risk behavior and socioeconomic factors that facilitate the acquisition and transmission of pathogens. The present study assessed the presence of HBV and HBV-HDV co-infection, identified viral sub-genotypes, and verified the occurrence of mutations in coding regions for HBsAg and part of the polymerase in HBV-infected PWUDs in municipalities of the Brazilian states of Amapá and Pará, in the Amazon region. In total, 1074 PWUDs provided blood samples and personal data in 30 municipalities of the Brazilian Amazon. HBV and HDV were detected by enzyme-linked immunosorbent assay and polymerase chain reaction. Viral genotypes were identified by nucleotide sequencing followed by phylogenetic analysis, whereas viral mutations were analyzed by specialized software. High rates of serological (32.2%) and molecular (7.2%) markers for HBV were detected, including cases of occult HBV infection (2.5%). Sub-genotypes A1, A2, D4, and F2a were most frequently found. Escape mutations due to vaccine and antiviral resistance were identified. Among PWUDs with HBV DNA, serological (19.5%) and molecular (11.7%) HDV markers were detected, such as HDV genotypes 1 and 3. These are worrying findings, presenting clear implications for urgent prevention and treatment needs for the carriers of these viruses.

Abstract
In the present study, we evaluated the prevalence of occult hepatitis B (OBI) in a population from the Brazilian Amazon region, identify circulating genotypes, and mutations in the S gene. One hundred eighty-one patients with negative serology for HBsAg and anti-HBs and positive serology for anti-HBc participated in the study. Detection of viral DNA, genotyping by sequencing, and analysis of nucleotide sequences to detect possible mutations were performed. HBV DNA was detected in 14.36% of the patients. Genotyping revealed genotype A in 88.46% of HBV DNA-positive subjects, with subgenotype A1 being the most prevalent (78.26%) followed by subgenotype A2 (21.74%). Genotype F was detected in 11.54% (all of them subgenotype F2). Amino acid substitutions were observed in the amplified S gene in individuals with OBI compared to HBsAg-positive individuals (evident infection). In conclusion, the results show a high prevalence of OBI in the population studied, with a pattern of genotypes A and F that circulate in the Brazilian Amazon region. Amino acid substitutions were detected in part of the S gene in patients with OBI. Further studies on the molecular epidemiology of HBV in this region are important to identify patients considered healthy but who are potential transmitters of the disease.
