    الوصف: WOS: 000481718600008 ; Objective: This study aimed to evaluate the awareness and knowledge levels of all physicians administering immunosuppressive treatment concerning hepatitis B virus (HBV) reactivation, and draw attention to the importance of the subject through evaluation. Methods: The study was carried out by infectious diseases and clinical microbiology specialists in 37 health centers, and it was performed in Turkey between January and March 2017. All specialists providing a written consent and working in the departments of Medical Oncology, Hematology, Dermatology and Venereology, Physical Medicine and Rehabilitation, and Rheumatology of each study center were included in the study. Results: A total of 430 physicians participated in the study. Their mean age was 39.87 +/- 7.42 years, and 47.9% of them were males. During their career, 39.3% of these physicians had encountered patients developing HBV reactivation while receiving immunosuppressive treatment. The rate of encountering patients who died due to HBV reactivation was 6.5%. 97% of physicians who participated, considered the risk of HBV reactivation to be important. 70.2% of physicians stated that guidelines related to HBV reactivation and antiviral treatment for these patients were discussed in the congresses they participated, regarding their specialties. The rate of performing hepatitis screening among physicians whose patients developed HBV reactivation was statistically significantly higher than those physicians who had no patients with HBV reactivation (p<0.05). Physicians who used the guidelines related to HBV reactivation in their specialties performed screening for the HBV infection much more often than physicians who did not use the guidelines (p=0.002). Conclusions: According to the results obtained in our study, the rates of conducting screening and awareness of HBV reactivation among physicians administering immunosuppressive treatment were higher compared with similar studies; however, their awareness that HBV DNA and anti-HBc ...

In this study, we aimed to investigate the predictors of response to pegIFN treatment in cases with HBeAg-negative CHB infection. Methodology: Seventeen tertiary care hospitals in Turkey were included in this study. Data from consecutively treated HBeAg-negative CHB patients, who received either pegIFN alpha-2a or alpha-2b, were collected retrospectively. SVR is defined as an HBV DNA concentration of less than 2,000 IU/mL six months after the completion of therapy Results: SVR was achieved in 40 (25%) of the 160 HBeAg-negative CHB patients. Viral loads in patients with SVR were lower compared to those with no SVR, beginning in the third month of treatment (p < 0.05). The number of cases with a decline of 1 log(10) IU/mL in viral load after the first month of treatment and with a serum HBV DNA level under 2,000 IU/mL after the third month of treatment was higher in cases with SVR (p < 0.05). The number of patients who had undetectable HBV DNA levels at week 48 among responders was significantly greater than among post-treatment virological relapsers (p < 0.05). Conclusions: Detection of a 1 log(10) decline in serum HBV DNA level at the first month of treatment and a serum HBV DNA level < 2000 IU/mL at the third month of therapy may be predictors of SVR.

    الوصف: WOS:000368020900002 ; PubMed: 26369498 ; Aim: The aim of the present study was to assess the potential risk of hepatitis B virus (HBV) vertical transmission among Turkish parturient women and to evaluate the efficacy and safety of antiviral agents. Material and Methods: Data were collected retrospectively from 114 HBV-infected pregnant women and their infants in eight health institutions in Turkey. Results: The baseline characteristics of the women were: mean age, 28.3 +/- 5.2 years; alanine aminotransferase, 57.4 +/- 139.0 U/L; aspartate aminotransferase, 56.6 +/- 150.0 U/L; and HBV DNA, 8.3 x 10(7) +/- 2.6 x 10(8) copies/mL. Family history of HBV infection was detected in 53.5% (n = 61). In total, 60 (52.6%) pregnant women received tenofovir (60.0%), lamivudine (33.3%) or telbivudine (6.7%) therapy at the median gestational age of 22.2 +/- 8.5 (1-36) weeks. All infants were vaccinated and hepatitis B immune globulin was administered, with 81 of them (71.1%) available for follow-up. After completion of HBV vaccination course, 71 (87.7%) infants had protective anti-HBs levels, three (3.7%) were hepatitis B surface antigen-positive, and seven (8.6%) were hepatitis B surface antigen-negative with nonprotective anti-HBs levels. Five of the infants had low gestational birthweight but no other birth defects were observed. Conclusion: According to our results, viral load may not be the only effecting factor for transmission of HBV to children of infected mothers. Pregnant women with high viral load should be followed-up closely during pregnancy. They should begin to take tenofovir or telbivudine, which are category B drugs for pregnancy, at the beginning of the third trimester at the latest. We need new treatment strategies; and close follow-up of mothers and children is another important issue.

    مستخلص: Background: Hepatitis B virus (HBV) has a high mutation rate due to its unusual replication strategy leading to the production of a large number of virions with single and double mutations. The mutations, in turn, are associated with the development of drug resistance to nucleos(t)ide analogs (NUCs) in patients before and during NUCs therapy. Objectives: The current study aimed at investigating the molecular characterization of HBV in Turkish patients with chronic hepatitis B (CHB) infection. Methods: Polymerase chain reaction (PCR) amplificationanddirect sequencing procedures were used to analyze mutations. The detected drug resistance mutations were divided into the nucleos(t)ide analogs primary, partial, and compensatory resistance groups. The amino acid substitutions of hepatitis B surface antigen (HBsAg) were categorized into antiviral drug - associated potential vaccine - escape mutations (ADAPVEMs) and typical HBsAg amino acid substitutions, which included hepatitis B hyperimmunoglobulin (HBIg) - selected escape mutation, vaccine escape mutation, hepatitis B misdiagnosis, and immune - selected amino acid substitutions. Results: The number of patients included in the study was 528 out of which 271 (51.3%) were treatment - naive and 351 (66.3%) were hepatitis B e antigen (HBeAg) - negative. Moreover, 325 (61.6%) were males with a mean age of 38 years (range: 18 - 69). Primary, partial, and compensatory resistance to NUCs was reported in 174 (32.9%) patients. Six different ADAPVEM motifs were determined in both treatment - naive and treatment - experienced patients, namely, sF161L/rtI169X, sE164D/rtV173L, sL172L/rtA181T, sL173F/rtA181V, sS195M/rtM204V, and sS196L/rtM204I. The prevalence of ADAPVEMs and typical HBsAg escape mutations was 5.3% (n = 28) and 34.8% (n = 184), respectively. Conclusions: The analysis of drug resistance should constitute a fundamental part of the follow - up period of patients with CHB undergone treatment with NUCs. The surveillance of development of drug resistance mutations, while receiving treatment for hepatitis B is of paramount importance to monitor and control the emerging resistance.
