“…In epidemiological studies examining the seroprevalence of HBsAg, a prevalence ranging from 2% to 7% has been reported, varying between regions in Turkey. In general, the prevalence of HBV in the eastern part of Turkey is higher than 4% (13). In the present study, 4.5% of the PLHIV had HBV co-infection, consistent with the figures reported in the general Turkish population.…”

Objectives: This study was undertaken to assess the prevalence of HBV/HCV co-infection demographic characteristics of HIV/HBV and HIV/HCV co-infected patients and its risk factors in a group of HIV infected patients followed-up in an infectious diseases and clinical microbiology clinic. Methods: Treatment-naïve patients attending the clinic between January 2015 and June 2018 were included. Sociodemographic characteristics of the participants, HIV infection risk factors, and laboratory findings were retrospectively evaluated using medical records.Results: Out of 717 patients, 645 were male with the mean age of 35.94 ± 11.69 years, of whom 270 (37.6%) were late presenters, and 377 (52.5%) were men who had sex with men (MSM). Of the patients, four out of 717 patients (0.5%) had HCV infection, and 32 (4.5%) had HBV co-infection. The heterosexual (HS) patients were significantly more likely to have HBV co-infection (P = 0.03). A comparison of the MSM and HS patients showed that the latter group of patients were significantly older and more likely to be late presenters (P < 0.001). Anti-HBc was positive in 216 of the patients (30.1%) who were considered to have previous exposure to HBV. A comparison of educational status in the patients showed that 70% of the MSM patients were high-school or university graduates (P = 0.008). Moreover, anti-HBs was positive in 65.7% of the MSM patients, and MSM and Heterosexual patients were not significantly different in terms of the presence of resolved HBV infection (P = 0.05). Conclusions: Our study showed that the prevalence of HBV co-infection among the HIV infected patients was similar to the prevalence of HBV infection in the general population and that patients with the heterosexual route of transmission had higher rates of seropositivity. A high occurrence of co-infections in HS patients suggests that infections are likely to follow a chronic course in those with a delayed diagnosis. MSM patients who were known in the high-risk group for HIV infection, have higher vaccination ratios and education levels. So the efforts to increase awareness must not only be limited to high-risk groups but also all individuals.

“…In a study conducted in South Asia, it was reported that the positivity of patients who over 55 years old was more than 7% (13,19). In some researches conducted in Turkey, over 50 age is recognized as an important risk factor for seropositivity (22). This situation also shows that the risk of HCV encountering with the age increases in the society.…”

Aim: We aimed to investigate the alteration and distribution of seroprevalence of hepatitis B and hepatitis C within the years according to age groups in patients who applied to our hospital. Materials and Methods: The patients have been evaluated for six years retrospectively who were admitted to third step hospital in Istanbul. The duplicate results of patients who submitted more than one application within the same year were excluded from this study. Male and female patients were divided into four age groups as 0-14, 14-25, 25-49 and over 49 years old. Electrochemiluminescence method (Roche Cobas 6000, Germany) was used for HBsAg and anti-HCV assays. Results: HBsAg positivity was 2.97% and anti-HCV positivity was 1.35%. HBsAg positivity was higher in males, and anti-HCV positivity was higher in females. No significant increase in seroprevalences of anti-HCV and HBsAg was observed during the six years observation period. HBsAg seroprevalences decreased in years especially in 0-14 and 14-25 year-old male groups. HBsAg seroprevalence was not decreased in the other age groups over the years. There was no significant difference in anti-HCV seroprevalence over the years. HBsAg positivity was higher in males and anti-HCV positivity was higher in females. Anti-HCV and HBsAg seroprevalence were not significantly differed over the years. Conclusion: It was remarkable that HBsAg positivity rate had decreased over the years especially in 0-14 and 14-25 year-old males. Seroprevalence of HBsAg did not decrease in years in other age groups. There was no significant difference in the seroprevalence of anti-HCV during the measurement period.
