    (Medical Association of Zenica-Doboj Canton, 2014) Kemal Celen M.; Tekin Koruk S.; Aygen B.; Dal T.; Karabay O.; Tosun S.; Koksal I.
    Aim To evaluate the characteristics of patients with hepatitis B virus (HBV) infection and summarize the treatment modalities. Methods By September 30, 2011 the data of 7871 HBsAg (+) patients were complied and analysed according to demographic and medical records (age, sex, laboratory tests, treatment with antiviral agents) in thirty centres of Turkey. Results Of the 7871 patients 3078 (39.1%) were females; mean (standard deviation) age was 35 (14) years, 3180 (40.4%) were HBsAg positive (+) after admission to a hospital, 1488 (18.9%) after blood donation and 967 (11.9%) were found during routine screening. The HBV prevalence among relatives of HBsAg (+) patients was 1764 (22.4%), and most frequently infected family members were siblings and mothers, 4961 (63.0%) and 2149 (27.3%), respectively). Anti-HDV was negative in 7407 94.1% of patients. Three-fourths of the patients 6383 (81.1%) were HBeAg negative (-). Mean (SD) ALT was 85.8 (266.4) U/L. Majority of patients, 5588 (71.0%) were chronic hepatitis-B patients under treatment, while 2283 (29.0%) were asymptomatic carriers without treatment and only 165 (2.1%) of patients were cirrhotic and 6612 (84.0%) of those were compensated. One-third of the patients 2983 (37.9%) were under a combined treatment, while others were under monotherapy. Lamivudine, entecavir and adefovir were the most frequently used oral therapies, used for 2583 (32.8%), 11.6% and 787 (10.0%) of patients, respectively), while 2975 (37.8%) of patients were under interferon treatment. Conclusion Hepatitis B is still a problem in our country. First task of the physicians and our state should be to prevent the development and spread of the disease with education and vaccination programs, safe blood transfusions, and control of barbers.

    Epidemiology and risk factors of hepatitis delta infection in Turkey
    (2013) Ayaz C.; Koruk S.T.; Yalci A.; Yamazhan T.; Aygen B.; Tosun S.; Dal T.
    This study is aimed to investigate the prevalence and risk factors of HDV co-infection in patients with chronic HBV infection in Turkey, where HBV infection is endemic. The date of this study was obtained from Turk-Hep-Net project. The project includes real-life cohort of HBV patients from 15 centers in Turkey and is supported by Viral Hepatitis Society. Of the 7366 HBsAg positive individuals tested for the presence of anti-HDV antibodies, 63,6 were male and 36.4 % were female. Of the 7366 HBsAg positif patients, 206 (2.8%) contained anti-HDV. Southeastern Anatolia Region of the country's anti-HDV positivity rate was found to be 4.5%. The risk factors in anti-HDV positivity patient were; male gender, long-term (>5 year) HBsAg positivity and living in Southeastern Anatolia. Our study revealed that recognizing the risk factors associated with HBV and HDV co-infection will be beneficial to control of these infections.

    The prevalence and epidemiological characteristics of hepatitis B virus and hepatitis C virus coinfection in Turkey
    (Turkiye Klinikleri, 2013) Aygen B.; Çelen M.K.; Köksal I.; Tosun S.; Karabay O.; Yamazhan T.; Yildiz O.
    We aimed to determine prevalence and epidemiological characteristics of cases coinfected with hepatitis B virus (HBV)/hepatitis C virus (HCV) in Turkey. Material and Methods: The data for this study was obtained from Turk-Hepatitis Registry (HEP-NET) Project, which includes real-life cohort of hepatitis patients from 15 centers in Turkey, and is supported by Viral Hepatitis Society. In the project, 10,165 hepatitis cases were evaluated in 10 hospitals. Results: According to initial visit results, HBV/HCV coinfection was detected in 99 patients. The ratio was 974/100 000. The mean age of the cases was 40.9+21.7 years, 56.6% of them were males and 43.4% were females,. The major risk factors were dental therapy, any surgical procedure, hemodialysis and blood transfusion. The mean alanine aminotransferase (ALT) levels were 70.9±49.1 IU/L in coinfected patients. In 12% of cases HBeAg was positive. The median HCV RNA level was found 0 IU/mL (minimum: 50-maximum: 2.18x107 IU/mL), and the median HBV DNA level was found 2.50x102 IU/mL (minimum: 12-maximum: 1.70x108 IU/mL). In 8.1% of the patients both HCV RNA and HBV DNA were positive, and in 87.5% of cases HCV infection was dominant. The most important risk factor was hemodialysis (25%) in this group. Conclusion: This is the most detailed study which evaluates the prevalence of HBV/HCV coinfection in Turkey. HBV/HCV coinfection prevalence was not higher than HBV or HCV monoinfections. In cases where both HCV RNA and HBV DNA were positive, HCV was predominant. © 2013 by Türkiye Klinikleri.
