Abstract Background Despite recent advances through the development pipeline, how novel tuberculosis (TB) vaccines might affect rifampicin-resistant and multidrug-resistant tuberculosis (RR/MDR-TB) is unknown. We investigated the epidemiologic impact, cost-effectiveness, and budget impact of hypothetical novel prophylactic prevention of disease TB vaccines on RR/MDR-TB in China and India. Methods We constructed a deterministic, compartmental, age-, drug-resistance- and treatment history-stratified dynamic transmission model of tuberculosis. We introduced novel vaccines from 2027, with post- (PSI) or both pre- and post-infection (P&PI) efficacy, conferring 10 years of protection, with 50% efficacy. We measured vaccine cost-effectiveness over 2027–2050 as USD/DALY averted-against 1-times GDP/capita, and two healthcare opportunity cost-based (HCOC), thresholds. We carried out scenario analyses. Results By 2050, the P&PI vaccine reduced RR/MDR-TB incidence rate by 71% (UI: 69–72) and 72% (UI: 70–74), and the PSI vaccine by 31% (UI: 30–32) and 44% (UI: 42–47) in China and India, respectively. In India, we found both USD 10 P&PI and PSI vaccines cost-effective at the 1-times GDP and upper HCOC thresholds and P&PI vaccines cost-effective at the lower HCOC threshold. In China, both vaccines were cost-effective at the 1-times GDP threshold. P&PI vaccine remained cost-effective at the lower HCOC threshold with 49% probability and PSI vaccines at the upper HCOC threshold with 21% probability. The P&PI vaccine was predicted to avert 0.9 million (UI: 0.8–1.1) and 1.1 million (UI: 0.9–1.4) second-line therapy regimens in China and India between 2027 and 2050, respectively. Conclusions Novel TB vaccination is likely to substantially reduce the future burden of RR/MDR-TB, while averting the need for second-line therapy. Vaccination may be cost-effective depending on vaccine characteristics and setting.

Introduction: Treatment of multi drug resistant Mycobacterium tuberculosis (MDR-TB) with second line drugs is associated with adverse drug reactions and toxicity. Aim of this study were to determine side effects associated with drugs used in treatment of multi drug resistant tuberculosis and treatment related factors of MDR-TB patients.Methodology: A prospective study was carried out in National Tuberculosis Centre Bhaktapur Nepal. Questionnaires were used to collect data from patients.Results: Total 101 MDR TB patients were included among them majorities were male (52%) and mean age of the patients was 31.2 years. Majority of patients (87.1%) had previous history of tuberculosis treatment and 54.5% were in intensive phase of treatment. The side effect associated with drugs used in treatment of MDR-TB reported by patients were joint pain (21.2%), nausea (20.3%), hearing disturbances (11%), gastrointestinal disturbance (9.9%), depression (9.6%), itching (8.1%), hypothyroidism (6.4%), dizziness (6.4%), seizures (3.8%) and hepatitis (3.5%). Last month 25.74% patients missed one or more doses of drugs and 3.9% missed drug doses due to side effect of drugs. Majorities of the patients used vehicle to reach health centre (92.07%), time to reach the health center (59.4%) were less than 30 minutes but majorities of patients (57.4%) were not satisfied by the counseling of health care worker.Conclusion: The finding of this study shows that in MDR patients 12.8% were found new cases. Last month 3.9% patients were stopped the drugs due to side effects of drugs. Majority of patients (57.4%) were not satisfied by counseling of health care worker. Treatment of multi drug resistant tuberculosis with second line anti tubercular drugs is associated with side effects, health care worker counseling to MDR- TB patients with full attention is essential to encourage the patient’s moral and complete the treatment. Timely managing the side effects of medication is important in helping people to complete their treatment.SAARC J TUBER LUNG DIS HIV/AIDS, 2017; XIV(1), Page: 1-6

AbstractDrug-resistant tuberculosis (DR-TB) has been an area of growing concern and posing threat to human health worldwide. The treatment has been defined for all types of DR-TB with or without newer anti-TB drugs. multi-DR-TB (MDR-TB) patients have now choice of two types of regimen, shorter and longer regimens. Shorter regimen for treatment of subset of MDR-TB patients who have not been previously treated with second line drugs and in whom resistance to fluoroquinolones and second-line injectable agents has been excluded is given for 9 to 11 months. A longer regimen of at least five effective anti-TB drugs (ATDs) during the intensive phase is recommended, including pyrazinamide and four core second-line ATDs. Intensive phase, including injectables, should be given for at least 8 months. The total duration of treatment is at least 20 months, which can be prolonged up to 24 months depending on the response of the patient. World Health Organization (WHO) has recently revised the grouping of ATD for use in DR-TB patients in 2018 into three groups based on individual patient data meta-analysis depending on their individual efficacy, risk of relapse, treatment failure, and death. Recently, an all oral longer regimen comprising bedaquiline, pretomanid, and linezolid (BPal regime) for 6 to 9 months for extensive-DR-TB (XDR-TB) patients and those MDR-TB patients who cannot tolerate or do not respond to conventional MDR-TB regimen. These new developments will be a step forward toward establishing universal regimen to treat all types of DR-TB. This article has summarized the current evidence from literature search to date, including prevalence of DR-TB, types of regimen used and the advancement in the regimens for effective treatment of DR-TB patients.
