Depression and anxiety in patients with multidrug-resistant tuberculosis in Nepal: an observational study

SETTING: Multidrug-resistant tuberculosis (MDR-TB) patients in the national TB treatment programme of Nepal. OBJECTIVE: To estimate the prevalence of depression and anxiety in people receiving treatment for MDR-TB, identify potential risk factors for depression and anxiety and determine temporal changes in their severity during treatment. DESIGN: An observational study using a screening tool, the Hopkins Symptom Checklist (HSCL-25) for depression and anxiety, administered monthly to a group of 135 patients in Nepal. Logistic and multilevel linear regression models were used to identify any patient characteristics associated with depression and anxiety. RESULTS: Most of the 135 patients were male (76%) and living with their families (68%). The period prevalences of depression and anxiety were respectively 22.2% and 15.6%. Patients reporting physical side effects of MDR-TB treatment had a higher depression score on HSCL by 2.63 points (95%CI 0.77-4.48) and a 1.59 point higher anxiety score (95%CI 0.45-2.73) than those who did not report any side effects. Being single was associated with having anxiety (aOR 0.2, 95%CI 0.03-1.0). CONCLUSION: Given the high rates of depression observed among MDR-TB patients, national TB treatment programmes should ensure their patients are routinely screened for depression and anxiety, and effective treatment offered.
