India carries one quarter of the global burden of multi-drug resistant TB (MDR-TB) and has an estimated 2.5 million people living with HIV. Despite this reality, provision of treatment for MDR-TB is extremely limited, particularly for HIV-infected individuals. Médecins Sans Frontières (MSF) has been treating HIV-infected MDR-TB patients in Mumbai since May 2007. This is the first report of treatment outcomes among HIV-infected MDR-TB patients in India.

BACKGROUND
Childhood and adolescent drug-resistant TB (DR-TB) is one of the neglected infectious diseases. Limited evidence exists around programmatic outcomes of children and adolescents receiving DR-TB treatment. The study aimed to determine the final treatment outcomes, culture conversion rates and factors associated with unsuccessful treatment outcome in children and adolescents with DR-TB.
METHODS
This is a descriptive study including children (0-9 years) and adolescents (10-19 years) with DR-TB were who were initiated on ambulatory based treatment between January 2017-June 2018 in Shatabdi hospital, Mumbai, India where National TB elimination programme(NTEP) Mumbai collaborates with chest physicians and Médecins Sans Frontières(MSF) in providing comprehensive care to DR-TB patients. The patients with available end-of-treatment outcomes were included. The data was censored on February 2020.
RESULT
A total of 268 patients were included; 16 (6%) of them were children (0-9 years). The median(min-max) age was 17(4-19) years and 192 (72%) were females. Majority (199, 74%) had pulmonary TB. Most (58%) had MDR-TB while 42% had fluoroquinolone-resistant TB. The median(IQR) duration of treatment (n = 239) was 24(10-25) months. Median(IQR) time for culture-conversion (n = 128) was 3(3-4) months. Of 268 patients, 166(62%) had successful end-of-treatment outcomes (cured-112; completed treatment-54). Children below 10 years had higher proportion of successful treatment outcomes (94% versus 60%) compared to adolescents. Patients with undernutrition [adjusted odds-ratio, aOR (95% Confidence Interval, 95%CI): 2.5 (1.3-4.8) or those with XDR-TB [aOR (95% CI): 4.3 (1.3-13.8)] had higher likelihood of having unsuccessful DR-TB treatment outcome.
CONCLUSIONS
High proportion of successful treatment outcome was reported, better than global reports. Further, the nutritional support and routine treatment follow up should be strengthened. All oral short and long regimens including systematic use of new TB drugs (Bedaquiline and Delamanid) should be rapidly scaled up in routine TB programme, especially for the paediatric and adolescent population.

SETTING
While surgery for pulmonary tuberculosis (PTB) is considered an important adjunct for specific cases, including drug-resistant tuberculosis, operational evidence on its feasibility and effectiveness is limited.
OBJECTIVE
To describe surgical outcomes and programmatic challenges of providing surgery for PTB in Mumbai, India.
DESIGN
A descriptive study of routinely collected data of surgical interventions for PTB from 2010 to 2014 in two Mumbai hospitals, one public, one private.
RESULTS
Of 85 patients, 5 (6%) died and 17 (20%) had complications, with wound infection being the most frequent. Repeat operation was required in 12 (14%) patients. Most procedures were performed on an emergency basis, and eligibility was established late in the course of treatment. Median time from admission to surgery was 51 days. Drug susceptibility test (DST) patterns and final treatment outcomes were not systematically collected.
CONCLUSION
In a high-burden setting such as Mumbai, important data on surgery for PTB were surprisingly limited in both the private and public sectors. Eligibility for surgery was established late, culture and DST were not systematically offered, the interval between admission and surgery was long and TB outcomes were not known. Systematic data collection would allow for proper evaluation of surgery as adjunctive therapy for all forms of TB under programmatic conditions.

Treatment experiences with patients co-infected with human immunodeficiency virus (HIV) and hepatitis B virus (HBV) in resource-limited settings remain poorly documented. This study aimed to evaluate the treatment outcomes in a cohort of HIV/HBV co-infected individuals receiving tenofovir/lamivudine (TDF/3TC)-based antiretroviral therapy (ART) in a programmatic setting in Mumbai, India. Additionally, a cross-sectional laboratory study was carried out measuring serologic and virologic parameters. A total of 57 patients who received TDF/3TC were included in the study. Of these, 52 (91%) were male and the mean age was 38.7 years. The median follow-up period was 16.8 months (IQR:7.9-37.9). Forty-three patients were included in the cross-sectional laboratory study, of whom 38 (67%) were HBeAg(+) positive. Four patients had serum HBsAg conversion to negative and had developed anti-HBs-antibodies. HBV-DNA became undetectable (<1.3 log10 copies/ml or <20 IU/ml) in 35.5% and 75% of the HBeAg(+) and HBeAg(-) patients, respectively. Overall, 46.5% of patients had undetectable HBV-DNA and 90.7% had adequately suppressed HBV-DNA (<3.3 log10 copies/ml or <2000 IU/ml). The median reduction in serum HBV-DNA was 6 log10 copies/ml. In 29 patients (63%) HIV viral load was undetectable. Outcomes included seven (12%) deaths, four (7%) lost to follow-up, one (2%) transferred out and 45 (79%) alive and on treatment. In conclusion, good treatment outcomes were achieved in a cohort of HIV/HBV co-infected patients in India. In regions with a high HIV/HBV burden, all HIV-infected individuals should be tested for chronic hepatitis B. A TDF/3TC-backbone could be considered as first-line standardized ART regimen in these settings.

BACKGROUND
In high TB burden countries, access to drug susceptibility testing is a major bottleneck. Targeted next-generation sequencing (tNGS) is a promising technology for rapid resistance detection. This study assessed the role of tNGS for the diagnosis of drug-resistant TB (DR-TB).
METHODS
A total of 161 samples from bacteriologically confirmed TB cases were subjected to tNGS using the Deeplex® Myc-TB kit and sequenced using the MiSeq platform. These samples were also processed for conventional phenotypic DST (pDST) using 13 drugs on Mycobacteria Growth Indicator Tube and line-probe assays (MTBDR plus and MTBDRsl).
RESULTS
There were 146 DR-TB and 15 drug-susceptible TB (DS-TB) samples. About 70% of patients with DR-TB had no previous TB treatment history. Overall, 88.2% had rifampicin-resistant/multidrug-resistant TB (RR/MDR-TB), 58.5% pre-extensively drug-resistant TB (pre-XDR-TB) and 9.2% had XDR-TB as defined by the WHO (2020). Around 8% (n=13) of samples were non-culturable; however, identified 8 were resistant to first and second-line drugs using tNGS. Resistance frequency was similar across methods, with discordance in drugs less reliable using pDST or with limited mutational representation within databases. Sensitivities were aligned with literature reports for most drugs. We observed 10% heteroresistance, while 75% of strains were of Lineages 2 and 3.
CONCLUSIONS
Programme data supported tNGS in the diagnosis of DR-TB for early treatment using individualised regimens.

Background
Imipenem, an intravenous antibiotic is recommended for use in drug resistant tuberculosis (DR-TB) when an effective regimen with combination of other second line drugs is not possible. Though the treatment success rates with carbapenems are promising, the twice daily injection of Imipenem usually requires patients to be hospitalized. The Médecins Sans Frontières independent clinic in Mumbai, India implemented ambulatory and home based management of patients receiving Imipenem through the use of port-a-cath.
Objective
We aimed to describe the adverse events and treatment outcomes of ambulatory pre- and XDR-TB patients initiated on imipenem through port-a-cath between January 2015 and June 2018 and to explore the challenges with this regimen as perceived by healthcare providers and patients.
Methods
A convergent mixed methods study with quantitative (longitudinal descriptive study using the routine data) and qualitative (descriptive study) part conducted concurrently. For the quantitative component, all XDR-TB and pre-XDR-TB initiated on imipenem containing regimen during January 2015-June 2018 were included. For qualitative component, interviews were carried out including patients who initiated on imipenem (n = 5) and healthcare providers (n = 7) involved in providing treatment. Treatment outcomes, culture conversion and adverse events during treatment were described. Thematic analysis was carried out for qualitative component.
Results
Of the 70 patients included, the mean age was 28.1 (standard deviation: 11.2) years and 36 (51.4%) were females. Fifty one (72.9%) had XDR-TB. All patients were resistant to fluoroquinilone, levofloxacin. Vomiting was reported by 55 (78.6%) patients and at least one episode of QTC prolongation (more than 500 msec by Fredrecia method) was detected in 25 (35.7%). Port-a-cath block and infection was seen in 11 (15.7%) and 20 (28.6%) patients respectively. Favourable outcomes were seen in 43 (61.4%) patients. Mortality was seen in 22 (31.4%) patients, 2 (2.9%) were lost-to-follow-up and 3 (4.3%) were declared as treatment failure. The overarching theme of the qualitative analysis was: Challenges in delivering Imipenem via port-a-cath device in ambulatory care. Major challenges identified were difficulties in adhering to drug dose timelines, vomiting, restricted mobility due to port-a-cath, paucity of infection control and space constraints at patients’ home for optimal care.
Conclusion
Administration of imipenem was feasible through port-a-cath. Though outcomes with ambulatory based imipenem containing regimens were promising, there were several challenges in providing care. The feasibility of infusion at day care facilities needs to explored to overcome challenges in infusion at patients home.
