Majority of patients using inhalation devices made errors while using the device. Proper education to patients on correct usage may not only improve control of the symptoms of the disease but might also allow dose reduction in long term.

Although a decline in ARTI was observed in two of the four zones and at national level, the current ARTI of about 1% in three zones suggests that further intensification of TB control activities is required.

IMPORTANCE The high household costs associated with tuberculosis (TB) diagnosis and treatment can create barriers to access and adherence, highlighting the urgency of achieving the World Health Organization's End TB Strategy target that no TB-affected households should face catastrophic costs by 2020.OBJECTIVE To estimate the occurrence of catastrophic costs associated with TB diagnosis and treatment and to identify socioeconomic indicators associated with catastrophic costs in a setting where TB control strategies have been implemented effectively. DESIGN, SETTING, AND PARTICIPANTSIn this cross-sectional study, 455 patients with TB in the Chennai metropolitan area of South India who were treated under the TB control program between February 2017 and March 2018 were interviewed. Patients were interviewed by trained field investigators at 3 time points: at the initiation of treatment, at the end of the intensive phase of treatment, and at the end of the continuation phase of treatment. A precoded interview schedule was used to collect information on demographic, socioeconomic, and clinical characteristics and direct medical, direct nonmedical, and indirect costs. Data analysis was performed from August 2018 to November 2019. MAIN OUTCOMES AND MEASURES Direct, indirect, and total costs to patients with TB.Catastrophic costs associated with TB were defined as costs exceeding 20% of the household's annual income. A binary response model was used to determine the factors that were significantly associated with catastrophic costs. RESULTSOf 455 patients with TB interviewed, 205 (53%) were aged 19 to 45 years (mean [SD] age, 38.4 [16.0] years), 128 (33%) were female, 72 (19%) were illiterate, 126 (33%) were employed, and 186 (48%) had a single earning member in the family (percentages are based on the 384 patients who were interviewed through the end of the continuation phase of treatment). Sixty-one percent of patients (234 patients) had pulmonary smear positive TB. The proportion of patients with catastrophic costs was 31%. Indirect costs contributed more toward catastrophic cost than did direct costs. Multivariate logistic regression analysis found that unemployment (adjusted odds ratio, 0.2; 95% CI, 0.1-0.5; P < .001) and higher annual household income (Rs 1-200 000, adjusted odds ratio, 0.4; 95% CI, 0.2-0.7; P = .004; Rs >200 000, adjusted odds ratio, 0.2; 95% CI, 0.1-0.5; P < .001) were associated with a decreased likelihood of experiencing catastrophic costs. CONCLUSIONS AND RELEVANCEDespite the implementation of free diagnostic and treatment services under a national TB control program, TB-affected households had a high risk of catastrophic (continued) Key Points Question What are the costs incurred by patients with tuberculosis (TB) throughout the treatment period in a resource-poor country such as India, where diagnostic testing and TB treatment are provided free of charge? Findings In this cross-sectional study of 455 individuals with TB, despite the implementation of free diagnostic and treatment services un...

Background Treatment success rates for multidrug-resistant tuberculosis (MDR-TB) remain low globally. Availability of newer drugs has given scope to develop regimens that can be patient-friendly, less toxic, with improved outcomes. We proposed to determine the effectiveness of an entirely oral, short-course regimen with bedaquiline and delamanid in treating MDR-TB with additional resistance to fluoroquinolones (MDR-TBFQ+) or second-line injectable (MDR-TBSLI+). Methods We prospectively determined the effectiveness and safety of combining 2 new drugs with 2 repurposed drugs—bedaquiline, delamanid, linezolid, and clofazimine—for 24–36 weeks in adults with pulmonary MDR-TBFQ+ and/or MDR-TBSLI+. The primary outcome was a favorable response at end of treatment, defined as 2 consecutive negative cultures taken 4 weeks apart. The unfavorable outcomes included bacteriologic or clinical failure during the treatment period. Results Of the 165 participants enrolled, 158 had MDR-TBFQ+. At the end of treatment, after excluding 12 patients due to baseline drug susceptibility and culture negatives, 139 of 153 patients (91%) had a favorable outcome. Fourteen patients (9%) had unfavorable outcomes: 4 deaths, 7 treatment changes, 2 bacteriological failures, and 1 withdrawal. During treatment, 85 patients (52%) developed myelosuppression, 69 (42%) reported peripheral neuropathy, and none had QTc(F) prolongation &gt;500 ms. At 48 weeks of follow-up, 131 patients showed sustained treatment success with the resolution of adverse events in the majority. Conclusions After 24–36 weeks of treatment, this regimen resulted in a satisfactory favorable outcome in pulmonary MDR-TB patients with additional drug resistance. Cardiotoxicity was minimal, and myelosuppression, while common, was detected early and treated successfully. Clinical Trials Registration. ClinicalTrials Registry of India (CTRI/2019/01/017310).

Illness for more than 2months, presence of cavity or extensive disease on chest X-ray, and interruption in intensive phase of treatment are independent risk factors for sputum smear positivity at two months, which in turn is associated with poor treatment outcomes. Patients with these factors merit special attention under the national program.
