The countries of Central Asia and the Caucasus are linked by travel and trade, which is promoted by visa-free mobility across borders. Unfortunately, this migrant mobility has given rise to the transmission of various infections within this region. Overlaps in culture, tradition, and behavior among these countries provide opportunities to share experiences that have proven effective in controlling transmission. Here we present a review of hepatitis B virus (HBV) prevalence, prevention and treatment across Central Asia and the Caucasus. Overall, owing to effective measures, while HBV prevalence has been steadily declining in the region, certain gaps still exist regarding the generation and availability of HBV infection data.

Introduction: HIV/TB comorbidity is responsible for 1.6 million deaths worldwide. HIV/TB control and patients’ survival are still among priorities of the national HIV and TB programs. We aimed to evaluate the HIV/TB survival in connection with TB treatment outcomes and factors influencing life duration of the cohort 2008-2018 in Almaty, Kazakhstan. Methodology: This retrospective cohort study extracted data for all HIV and pulmonary TB adults coinfected during 2008-2018 in Almaty from national registries to apply descriptive, Kaplan-Meier estimation, and Cox proportional hazards regression model. Survival function for the TB treatment outcomes and factors predicting the probability of survival were tested and described. Results: The cohort population (n = 521) mean age was 37.4 years with 405 (77.7%) males and 210 (40.3%) marrieds. More than one TB treatment had 181 (34.7%) patients, 291 (55.9%) were smear-positive (SS+), and 423 (81.2%) were on antiretroviral therapy with mean CD4 count 254.22cells/µL. Probability to live longer was higher (128 versus 37 months, p = 0.003; 95% confidence interval (CI) 71.65, 184.35) for those who succeeded in TB treatment compared to “lost to follow-up” and “failed” treatment outcomes. Adjusted Cox regression model death hazard showed association with missing ART treatment (HR: 1.699, 95%CI 1.164, 2.481, p = 0.006) and having CD4 count < 499 (HR 2.398, 95%CI 1.191, 4.830, p < 0.014). Conclusion: TB treatment outcomes, ART treatment, and the CD4 count of HIV/TB coinfected population substantially influence their life duration. The medical decision- and policy-makers should take this into consideration when implementing targeted improvements in the national HIV and TB programs.

BackgroundIn Kazakhstan, scarce official prevalence data exists for mood disorders. This study investigates the occurrence of depressive symptoms among people living with HIV/AIDS (PLWHA), and the relationship between depressive symptoms, HIV treatment initiation and antiretroviral treatment (ART) adherence.MethodsA cross-sectional study was conducted among patients seen at the Almaty AIDS Center between April and December 2013. Two data sources were used: 1) self-administered survey that included the Patient Health Questionnaire (PHQ-9) to capture depression symptoms and 2) medical record review. Two primary outcomes were evaluated with log-binomial models and Fisher’s exact test: the relationship between depression symptoms and 1) HIV treatment group, and 2) HIV adherence.ResultsOf the 564 participants, 9.9% reported symptoms consistent with a depressive disorder. None had received treatment for depression. Among those not on ART, a relationship between depressive symptoms and low CD4 counts (≤ 350 cells/mm3) was evident (7.1% for CD4 ≤ 350 cells/mm3 vs. 0.9% for CD4 > 350 cells/mm3, p = 0.029). In multivariable analysis, a higher prevalence of depressive symptoms was statistically associated with ART treatment, positive hepatitis C virus (HCV) status, and being unmarried. For those taking ART, treatment adherence was not statistically associated with a lower prevalence of depressive symptoms (12.5% vs 20.0%, p = 0.176); limited power may have impacted statistical significance.ConclusionsUntreated depression was found among PLWHA suggesting the need to evaluate access to psychiatric treatment. A collaborative strategy may be helpful to optimize HIV treatment outcomes.

The study purpose was to determine the factors associated with health-related quality of life (HRQoL) among people living with HIV (PLHIV) in Kazakhstan. A convenience sample of 531 adult PLHIV registered at the Almaty City AIDS Center was used for this cross-sectional study. HRQoL data were collected with the World Health Organization’s Quality of Life HIV brief questionnaire, depression – with Patient Health Questionnaire-9, and clinical data were retrieved from medical records. Multivariate logistic and Tobit censored regressions were used to examine the relationship of socio-demographic, behavioral, and clinical factors with HRQoL and the six specific HRQoL domains: 35.8% of participants did not report good HRQoL. The following variables were identified as independent predictors of poor HRQoL: probable depression (adjusted odds ratio [AOR] 13.42, 95% confidence interval [CI]: 4.56–39.52); history of injecting drug use (AOR 2.10, 95% CI: 1.40–3.14); CD4+ T-cell count <200 cells/mm3 (AOR 2.17, 95% CI: 1.30–3.62); previously married status (AOR 2.23, 95% CI: 1.16–4.28); and co-infection with tuberculosis, syphilis, toxoplasmosis, Chlamydia, herpes simplex, or cytomegalovirus (AOR 1.59, 95% CI: 1.06–2.39). HRQoL of PLHIV in Almaty was independently influenced by several factors. An interdisciplinary approach is needed in planning healthcare and social services addressing improvement of HRQoL among PLHIV.
