Untreated depression among persons living with human immunodeficiency virus in Kazakhstan: A cross-sectional study.

BACKGROUND: In 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. METHODS: A 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. RESULTS: Of 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. CONCLUSIONS: Untreated 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.

Developing effective HIV education in Central Asia: a cross-sectional study among Kazakh medical students.

INTRODUCTION: The HIV epidemic continues to expand in Central Asia, bridging from injecting drug users to the general population, largely through heterosexual transmission. This study describes medical students' attitudes and behaviours regarding HIV and sexual practices in response to recently introduced HIV curriculum. METHODOLOGY: Medical students in Almaty, Kazakhstan, were invited to participate in a cross-sectional survey between April and November, 2013. The survey assessed participant's risk behaviours (e.g., injecting drug use, condom use), concerns related to HIV infection risk (e.g., medical care exposures, personal behaviours), and ability to identify HIV-positive individuals without asking their status. Bivariate analyses (Chi-square test or Fisher's exact test) and multivariate analysis (log-binomial regression) were conducted. RESULTS: Of 647 medical students, the majority were female (82.2%) and single (92.8%) with a median age of 21-22 years. Sexual activity was reported by 176 (27.2%); males were substantially more likely to report sexual activity (74.8% males vs. 16.9% females, p <.0001). The majority of sexually active medical students (65.6% and 68.3% males and females, respectively) believe they can determine if their partner is HIV-positive without asking or seeking a laboratory test. This proportion is much higher (92.6%) among married or cohabitating women. No association between perceived ability to ascertain HIV status and condom use was identified. CONCLUSIONS: The medical students in our study had a relatively naïve perception of HIV risk, and their knowledge of risk did not translate to appropriate precautionary behaviours. Much work remains if the epidemic in Central Asia is to be contained.

Relationship between vitamin D and human immunodeficiency virus (HIV) viral load among HIV-infected patients in Kazakhstan.

INTRODUCTION: Human immunodeficiency virus (HIV) is associated with inflammation. An association between vitamin D deficiency and inflammation also exists. Our study attempts to examine whether there may be a relationship between vitamin D and HIV viral load (HIV RNA) by: 1) characterizing the distribution of 25-hydroxyvitamin D (25-OHD), and 2) determining if 25-OHD is independently associated with HIV RNA. METHODOLOGY: A cross-sectional study among HIV-infected adults was conducted. Demographics, clinical / social / HIV characteristics and data on antiretroviral therapy were collected by questionnaire, medical records and laboratory testing. All patients provided blood samples. Bivariate and multivariate analyses were conducted to quantify the relationship between vitamin D and HIV RNA. RESULTS: Among the 564 patients, the median (interquartile range, IQR) 25-OHD value was 24.42 (16.22 - 34.10) ng/mL. The mean (standard deviation, SD) log-HIV RNA was 3.51 (1.11) copies/mL. There were 304 patients (53.9%) with an undetectable HIV RNA (< 500 copies/mL). In the bivariate analyses, no differences were observed between patients with and without an undetectable HIV RNA in mean (SD) 25-OHD, 25-OHD insufficiency (< 30 ng/mL), or 25-OHD deciles. In the log-binomial regression analyses, there was no association between 25-OHD and an undetectable HIV RNA (prevalence ratio: 1.00, 95% confidence interval: 0.99 - 1.01, p = 0.67). CONCLUSIONS: No relationship was observed between 25-OHD and HIV RNA among HIV-infected patients in Kazakhstan.
