Abstract Background The aim of this study was to assess the treatment outcomes of multidrug and extensively drug-resistant tuberculosis (M/XDR-TB) in Zhejiang, China and to evaluate possible risk factors associated with poor outcomes of M/XDR-TB. Methods Two-hundred-and-sixty-two patients having M/XDR-TB who received the diagnosis and treatment at nine referral hospitals from 1 January 2016 to 31 December 2016 in Zhejiang, China were included. All patients received second-line regimens recommended by WHO under the DOTS-Plus strategy. Results Among the 262 patients, the treatment success rate was 55.34% (n = 145) with 53.44% (n = 140) cured and 1.91% (n = 5) who completed treatment, 62 (23.66%) failed, 27 (10.31%) died, 16 (6.11%) defaulted and 12 (4.58%) transferred out. Forty (64.52%) of the 62 M/XDR-TB patients who failed treatment were due to adverse effects in the first 10 months of treatment. Eighteen patients (6.37%) had XDR-TB. Treatment failure was significantly higher among patients with XDR-TB at 50% than that among patients with non-XDR-TB at 21.72% (P = 0.006). Failure outcomes were associated with a baseline weight less than 50 kg (OR, 8.668; 95% CI 1.679–44.756; P = 0.010), age older than 60 years (OR, 9.053; 95% CI 1.606–51.027; P = 0.013), hemoptysis (OR, 8.928; 95% CI 1.048–76.923; P = 0.045), presence of cavitary diseases (OR, 10.204; 95% CI 2.032–52.631; P = 0.005), or treatment irregularity (OR, 47.619; 95% CI 5.025–500; P = 0.001). Conclusion Treatment outcomes for M/XDR-TB under the DOTS-Plus strategy in Zhejiang, China were favorable but still not ideal. Low body weight (< 50 kg), old age (> 60 years), severe symptoms of TB including cavitary disease, hemoptysis and irregular treatment were independent prognostic factors for failure outcomes in patients with M/XDR-TB.

Mdr Tb

Uzbekistan has a high burden of drug-resistant tuberculosis (TB). Although conventional treatment for multidrug-resistant TB (MDR-TB) and extensively drug-resistant TB (XDR-TB) has been available since 2013, there has been no systematic documentation about its use and effectiveness. We therefore documented at national level the trends, characteristics, and outcomes of patients with drug-resistant TB enrolled for treatment from 2013–2018 and assessed risk factors for unfavorable treatment outcomes (death, failure, loss to follow-up, treatment continuation, change to XDR-TB regimen) in patients treated in Tashkent city from 2016–2017. This was a cohort study using secondary aggregate and individual patient data. Between 2013 and 2018, MDR-TB numbers were stable between 2347 and 2653 per annum, while XDR-TB numbers increased from 33 to 433 per annum. At national level, treatment success (cured and treatment completed) for MDR-TB decreased annually from 63% to 57%, while treatment success for XDR-TB increased annually from 24% to 57%. On multivariable analysis, risk factors for unfavorable outcomes, death, and loss to follow-up in drug-resistant TB patients treated in Tashkent city included XDR-TB, male sex, increasing age, previous TB treatment, alcohol abuse, and associated comorbidities (cardiovascular and liver disease, diabetes, and HIV/AIDS). Reasons for these findings and programmatic implications are discussed.

Linezolid Therapy

Linezolid may be effective in treating multidrug-resistant tuberculosis and extensively drug-resistant tuberculosis. We conducted a prospective, multicentre, randomised study to further evaluate the efficacy, safety and tolerability of linezolid in patients with extensively drug-resistant tuberculosis in China.65 patients who had culture-positive sputum for extensively drug-resistant tuberculosis were randomly assigned to a linezolid therapy group or a control group. Patients in the two groups adopted a 2-year individually based chemotherapy regimen. The linezolid therapy group was given linezolid at a start dose of 1200 mg per day for a period of 4–6 weeks and this was then followed by a dose of 300–600 mg per day.The proportion of sputum culture conversions in the linezolid therapy group was 78.8% by 24 months, significantly higher than that in the control group (37.6%, p<0.001). The treatment success rate in linezolid therapy group was 69.7%, significantly higher than that in the control group (34.4%, p=0.004). 27 (81.8%) patients had clinically significant adverse events in the linezolid group, of whom 25 (93%) patients had events that were possibly or probably related to linezolid. Most adverse events resolved after reducing the dosage of linezolid or temporarily discontinuing linezolid.Linezolid containing chemotherapy for treatment of extensively drug-resistant tuberculosis may significantly promote cavity closure, increase sputum culture-conversion rate and improve treatment success rate.

Abstract Background Treatment of drug-resistant tuberculosis (DR-TB) requires toxic and complex drug regimens. Dismal outcomes occur due to a delay in the report of susceptibility results. WHO endorses genotypic tests like line probe assay (Mtbdrsl) for an early diagnosis enabling start of robust treatment regimens. Data correlating Mtbdrsl and specific mutations with outcome are rare. Methods A concurrent cohort study was conducted on all patients diagnosed to have DR-TB between January 2016 and June 2017 in the departments of Pulmonary Medicine and Infectious Diseases at a tertiary care center in India. Patients aged >18 years with a positive Mtbdrsl (done on culture) or Mycobacterial culture were prospectively followed up till completion of therapy for assessment of outcomes. Patients were divided into 2 groups based on diagnostic method used: culture group and Mtbdrsl group. Risk factors for adverse outcomes were assessed. Results Total of 82 patients, of which 62.2% were males with a mean age of 32 years were included; 50 in the Mtbdrsl group and 32 in the culture group. Among these, 40.2% were multi-drug-resistant Tuberculosis (MDR-TB), 53.7% were Pre–XDR (pre-extensively drug resistant i.e, quinolone-resistant tuberculosis) and 6.1% were XDR (extensively drug-resistant TB). Isolated pulmonary involvement (46.3%) was common followed by disseminated TB (29.3%). Overall good outcome was seen in 39/82 (14.6% cured and 32.9% completed treatment) and bad outcome in 43/82 (41.5% lost to follow up, 7.3% treatment failure and 3.7% died). Good outcome was noted in Mtbdrsl group was 22/50 (44%) vs. 17/32 (53.1%) in the culture group. Mtbdrsl group had 140 days mean decrease in time to initiation of appropriate therapy but the odds of having a better outcome was 0.693 (CI: 0.284–1.690, P = 0.499). Among the 15 different types of mutations, FQ mutations gyrA 94Gly and gyrA 90Val comprised 15% each with gyrA 94Gly noted to have a poorer outcome [OR 2.5 (CI 0.471–13.265)]. All 5 patients with XDR TB (50 % had rrs 1401Gly mutation) had a poor outcome. Conclusion Contrary to what is expected, Mtbdrsl did not significantly contribute to better treatment outcomes. High-risk mutation gyrA 94Gly was prevalent and associated with poorer outcomes. Small sample size and a wide variety of mutations preclude generalizability of our results.
