'They prefer hidden treatment': anti-tuberculosis drug-taking practices and drug regulation in Karakalpakstan.

SETTING: The joint Médecins Sans Frontières/Ministry of Health Multidrug-Resistant Tuberculosis (MDR-TB) Programme, Karakalpakstan, Uzbekistan. OBJECTIVE: Uzbekistan has high rates of MDR-TB. We aimed to understand patients' and prescribers' attitudes to anti-tuberculosis drug prescription, regulation and drug-taking behaviour. METHODS: Participants (12 patients, 12 practitioners) were recruited purposively. Data were gathered qualitatively using field notes and in-depth interviews and analysed thematically. FINDINGS: Our analysis highlighted two main themes. First, shame and stigma were reported to increase the likelihood of self-treatment and incorrect use of anti-tuberculosis drugs, most commonly at the initial stages of illness. A health system failure to promote health information was perceived, leading to wrong diagnoses and inappropriate therapies. Motivated by shame, patients hid their condition by resorting to drug treatment options outside the programme, compounding the risk of chaotic management and dissemination of erroneous information through lay networks. Second, positive influences on treatment were reported through patients, practitioners and peers working effectively together to deliver the correct information and support, which acted to normalise TB, reduce stigma and prevent misuse of anti-tuberculosis drugs. CONCLUSION: Effective case finding, patient support and community education strategies are essential. Patients, practitioners and peers working together can help reduce stigma and prevent misuse of anti-tuberculosis drugs.

Multidrug-resistant tuberculosis in Uzbekistan: results of a nationwide survey, 2010 to 2011.

Multidrug-resistant tuberculosis (MDR-TB; resistance to at least rifampicin and isoniazid) is a global public health concern. In 2010­2011, Uzbekistan, in central Asia, conducted its first countrywide survey to determine the prevalence of MDR-TB among TB patients. The proportion of MDR-TB among new and previously treated TB patients throughout the country was measured and risk factors for MDR-TB explored. A total of 1,037 patients were included. MDR-TB was detected in 165 treatment-naïve (23.2%; 95% confidence interval (CI) 17.8%­29.5%) and 207 previously treated (62.0%; 95% CI: 52.5%­70.7%) patients. In 5.3% (95% CI: 3.1%­8.4%) of MDR-TB cases, resistance to fluoroquinolones and second-line injectable drugs (extensively drug resistant TB; XDR-TB) was detected. MDR-TB was significantly associated with age under 45 years (adjusted odds ratio: 2.24; 95% CI: 1.45­3.45), imprisonment (1.93; 95% CI: 1.01­3.70), previous treatment (4.45; 95% CI: 2.66­7.43), and not owning a home (1.79; 95% CI: 1.01­3.16). MDR-TB estimates for Uzbekistan are among the highest reported in former Soviet Union countries. Efforts to diagnose, treat and prevent spread of MDR-TB need scaling up.
