Prevalence of depression and anxiety in pulmonary tuberculosis patients and its association with unsuccessful treatment outcome: A prospective cohort study.

BACKGROUND: Pulmonary tuberculosis (TB) remains a major public health problem in Thailand. TB causes chronic disease which may cause physical disability, mental and socioeconomic problems in TB patients. Mental disorders may occur after TB infection or co-exist with the disease. This study assessed the prevalence of depression and anxiety among pulmonary TB patients and its association with treatment outcome. METHODS: This is a single-center prospective study. Pulmonary TB patients who were treated at a tertiary hospital, in both outpatient and in-patient settings, were enrolled into the study. Demographic data and Thai Hospital Anxiety and Depression Scale (HADS) score at baseline and at least 2 months after diagnosis were collected to evaluate the probability of depression and anxiety. Logistic regression model was used to analyze the data. Association between suspicious mental disorder and treatment outcome were evaluated at the end of each participant's treatment. RESULTS: One hundred and three participants were enrolled into the study on March 2018 to October 2019. The prevalence of probable depression and anxiety (Thai HADS score ≥11 from both test) were 7.8% and 6.8%, respectively. Unsuccessful treatment outcome rate was 10.7% (11/103). From the multivariate analysis, people previously treated/relapsed (aOR (95%CI): 7.04 (1.19-41.85), p = 0.03) and probable depression/anxiety with Thai HADS score ≥11 (10.12 (1.54-66.45), p = 0.02) were associated with unsuccessful treatment outcome. CONCLUSIONS: In this study, Thai HADS score could identify probable depression and anxiety among pulmonary TB patients, and its association with unfavorable treatment outcome. Clinicians should keep in mind that pulmonary TB can affect the mental status of the patients and therefore, should evaluate them and provide appropriate treatment.

Higher prevalence of QTc interval prolongation among virologically suppressed older people with HIV.

OBJECTIVE: To assess the prevalence, and factors associated with QTc interval prolongation, among 383 virologically suppressed people with HIV (PWH), without evidence of cardiovascular disease and active opportunistic infections in Thailand. DESIGN: Cross-sectional study. METHODS: Resting 12-lead digital ECGs were performed in 2019. QT interval corrected for heart rate (QTc) >450 ms in males and >460 ms in females was defined as QTc interval prolongation. We used multivariable logistic regression to investigate factors associated with QTc interval prolongation. RESULTS: Mean (standard deviation) age was 56 (5.5) years and 42% were female. The median current CD4+ was 619 (interquartile range [IQR] 487, 769) cells/mm 3 . The median duration of antiretroviral therapy (ART) was 11.9 (IQR 7.1-16.1) years. Commonly used ART were rilpivirine (37.9%), efavirenz (20.1%), atazanavir/ritonavir (15.7%), lopinavir/ritonavir (12.3%) and dolutegravir (5%). The prevalence of QTc interval prolongation was 22.7%. In multivariable analysis, older age (odds ratio [OR] 1.07, 95% confidence interval [CI] 1.02-1.12, P  = 0.005), female sex (OR 1.69, 95% CI 1.01-2.82, P  = 0.046) and increasing BMI (OR 1.08, 95% CI 1.01-1.15, P  = 0.03) were associated with QTc interval prolongation. With every 1-year increase in age, the odds of QTc interval prolongation increased by 7%. CONCLUSIONS: In this well-suppressed aging Asian HIV cohort, the prevalence of QTc interval prolongation was relatively high, and associated with increasing age, female sex, and higher BMI. For PLWH with these characteristics, QTc interval should be monitored before and after initiating any medications known to prolong QTc intervals, to prevent fatal cardiac arrhythmias.
