Change in Hepatitis B Surface Antibody Titers After Chemotherapy in Patients With Hematological Malignancies.

Background The change in hepatitis B surface antibody (anti-HBs) titers after chemotherapy (CT) in patients with hematological malignancy, affecting factors, and its clinical implications have not been sufficiently understood. Therefore, we aim to evaluate the change in anti-HBs titers and hepatitis B virus reactivation (HBVr) after CT. Methods This retrospective study enrolled patients with hematological malignancies who received CT between 2013 and 2021. All patients were followed up for HBVr and a change in anti-HBs titers for one year. Results Overall, 192 patients were included. In total, 33.9% of the patients were anti-HBs (+) and 26% of the patients were anti-HBc (+) ± anti-HBs (+). Hepatitis B virus (HBV) prophylaxis was given to 35 (70%) of 50 Anti-HBc (+) patients. Tenofovir disoproxil fumarate and entecavir prophylaxis were initiated in 25 (71.4%) and 10 (28.6%) patients, respectively. A significant decrease was found in anti-HBs titers of all patients (p=0.017). A significant decrease was also found in anti-HBs titers of HBc IgG (+) patients and those who received four or more courses of CT (p=0.025; p=0.041). HBVr was not diagnosed in any of the patients. Conclusion Chemotherapeutic agents administered for hematological malignancy have serious immunosuppression effects. In these patients, anti-HBs titers may decrease or become negative one year after CT. Anti-HBs titer before CT or its change after CT may not constitute a risk for HBVr patients who received HBV prophylaxis in line with current guidelines and these recommendations.

Evaluation of TyG index and TG/HDL-C ratio in HBeAg negative chronic hepatitis B infected patients.

Patients with hepatitis B e antigen (HBeAg) negative chronic HBV infection are regularly followed up. This study investigates the presence of insulin resistance and the relationship between hepatosteatosis and insulin resistance in patients with HBeAg negative chronic HBV infection using the TyG index and TG/HDL-C ratio. Patients with HBeAg negative chronic HBV infection who applied to the Infectious Diseases and Clinical Microbiology outpatient clinic between January 2019 and December 2020 were included in the study. Glucose, lipid panel, alanine amino transferase (ALT), acetyl amino transferase (AST), body mass index (BMI), TyG index, TG/HDL-C and hepatobiliary ultrasonography (USG) results were evaluated. The data were compared with the control group consisting of 308 HBsAg negative individuals. The study included 132 patients with a median age of 52 years. There was no significant difference between the patient and control groups regarding age, gender and BMI. Glucose, total cholesterol, TG, LDL, AST, ALT, TyG index and TG/HDL-C ratio were significantly higher in patient than in the control group. At the same time, the HDL value was significantly lower in the patients. There was a strong positive correlation between the TG and BMI, and a strong negative correlation between HDL levels and both TyG index and TG/HDL-C ratio. Our findings showed that the TyG index and TG/HDL-C ratio are helpful in the diagnosis of insulin resistance and hepatosteatosis in patients with HBeAg negative chronic HBV infection.

Socioeconomic Factors Related to Prevalence, Severity, and Contact Coverage of Depression in Primary Health Care.

Background: We determine factors related to the prevalence, severity, and contact coverage of depression using the Patient Health Questionnaire-9. Methods: This cross-sectional study included 1059 individuals who applied to primary health care in Ankara before the onset of pandemic restrictions. Contact coverage was evaluated to include mental health care users. Results: The prevalence of depression was 22.9%. Individuals who were unemployed (OR: 3.832; 95% CI: 2.053-7.151), women (OR: 1.646; 95% CI: 1.158-2.340), those without social support (OR: 1.933; 95% CI: 1.219-3.065), those who did not receive formal education (OR: 2.631; 95 % CI: 1.312-5.275), lower-income group (OR: 1.528; 95% CI: 1.071-2.180), and unmarried or divorced (OR: 2.644; 95% CI: 1.324-5.281) were found to be at risk of developing depression. Based on the linear regression model including patients diagnosed with depression, individuals who were unemployed (standardized ß: 0.190), women (standardized ß: 0.075), those without social support (standardized ß: 0.096), and those who were unmarried or single (standardized ß: 0.147) had the highest scale scores. Contact coverage for depression was 31.0%. Contact coverage was more likely in the upper-income group (OR: 2.239, 95% CI: 1.173-4.273). Conclusion: Although depression is common among primary health care applicants, contact coverage is low. Developing screening programs for depression in primary health care may help improve community mental health. Socioeconomic factors that contribute to the emergence, severity, and contact coverage of depression indicate health inequalities. The development and severity of depression are mostly due to unemployment, which suggests the importance of employment-enhancing policies.
