Abstract
BACKGROUND Nontuberculous mycobacteria are environmental organisms that are increasingly causing chronic and debilitating pulmonary infections, of which Mycobacterium avium complex (MAC) is the most common pathogen. MAC pulmonary disease (MAC-PD) is often difficult to treat, often requiring long-term multidrug antibiotic therapy. RESEARCH QUESTION Is there an association between various guideline-based three-drug therapy (GBT) regimens and (1) therapy-associated adverse events or (2) regimen change/discontinuation, within 12 months of therapy initiation? STUDY DESIGN AND METHODS In a retrospective cohort study, we examined tolerability outcomes of GBT regimens for MAC-PD in 4,626 US Medicare beneficiaries with bronchiectasis, who were prescribed a GBT as initial antibiotic treatment for presumed MAC-PD during 2006 to 2014. Using multivariable Cox proportional hazard regression, we estimated adjusted hazard ratios (aHRs) to compare the risk of adverse events and regimen change/discontinuations within 12 months of therapy initiation in various GBT regimens. RESULTS The cohort had a mean age ± SD of 77.9 ± 6.1 years at treatment start, were mostly female (77.7%), and were mostly non-Hispanic White (87.2%). The risk of regimen change/discontinuation within 12 months of therapy was higher for clarithromycin-based regimens than azithromycin-based regimens (aHR, 1.12; 95% CI, 1.04-1.20 with rifampin; aHR, 1.11; 95% CI, 0.93-1.32 with rifabutin as the companion rifamycin), and for rifabutin-containing regimens than rifampin-containing regimens (aHR, 1.49; 95% CI, 1.33-1.68 with azithromycin; aHR, 1.47; 95% CI, 1.27-1.70 with clarithromycin as the companion macrolide). The aHR comparing regimen change/discontinuation with clarithromycin-ethambutol-rifabutin and azithromycin-ethambutol-rifampin was 1.64 (95% CI, 1.43-1.64). INTERPRETATION Overall, an azithromycin-based regimen was less likely to be changed or discontinued than a clarithromycin-based regimen, and a rifampin-containing regimen was less likely to be changed or discontinued than a rifabutin-containing regimen within 12 months of therapy start. Our work provides a population-based assessment on the tolerability of multidrug antibiotic regimens used for the treatment of MAC-PD.

Abstract
BACKGROUND Results of retrospective studies have suggested clofazimine as an alternative for rifampicin in the treatment of Mycobacterium avium complex pulmonary disease (MAC-PD). RESEARCH QUESTION Is a treatment regimen consisting of clofazimine-ethambutol-macrolide noninferior to the standard treatment regimen (rifampicin-ethambutol-macrolide) in the treatment of MAC-PD? STUDY DESIGN AND METHODS In this single-center, nonanonymized clinical trial, adult patients with MAC-PD were randomly assigned in a 1:1 ratio to receive rifampicin or clofazimine as adjuncts to an ethambutol-macrolide regimen. The primary outcome was sputum culture conversion following 6 months of treatment. RESULTS Forty patients were assigned to receive either rifampicin (n = 19) or clofazimine (n = 21) in addition to ethambutol and a macrolide. Following 6 months of treatment, both arms showed similar percentages of sputum culture conversion based on an intention-to-treat analysis: 58% (11 of 19) for rifampicin and 62% (13 of 21) for clofazimine. Study discontinuation, mainly due to adverse events, was equal in both arms (26% vs 33%). Based on an on-treatment analysis, sputum culture conversion following 6 months of treatment was 79% in both groups. In the clofazimine arm, diarrhea was more prevalent (76% vs 37%; P = .012), while arthralgia was more frequent in the rifampicin arm (37% vs 5%; P = .011). No difference in the frequency of corrected QT interval prolongation was seen between groups. INTERPRETATION A clofazimine-ethambutol-macrolide regimen showed similar results to the standard rifampicin-ethambutol-macrolide regimen and should be considered in the treatment of MAC-PD. The frequency of adverse events was similar in both arms, but their nature was different. Individual patient characteristics and possible drug-drug interactions should be taken into consideration when choosing an antibiotic regimen for MAC-PD.

Abstract
BACKGROUND Treatment failure of Mycobacterium avium complex (MAC) pulmonary disease occurs in about 30% of people with cystic fibrosis (CF) and may be a result of abnormal drug concentrations. METHODS Prospective, cross-over, single-dose PK study of 20 pancreatic insufficient individuals with CF and 10 healthy controls (HC). CF subjects received simultaneous doses of oral azithromycin, ethambutol, and rifampin in the fasting state and with food and pancreatic enzymes, separated by two weeks. HC received fasting doses only. A non-compartmental model was used to estimate PK parameters of drugs and metabolites. RESULTS Azithromycin maximum concentration (Cmax ) was higher and rifampin Cmax was lower in fasting CF subjects compared to HC, while other PK measures, including those for ethambutol, were similar. Addition of food and enzymes did not improve the Cmax of the antimycobacterial drugs. Nineteen of 20 CF subjects had one or more abnormal Cmax z-scores in either the fasting or fed state (or both), when compared to HC. CONCLUSION PK profiles of azithromycin and ethambutol were similar between CF and HC, except azithromycin Cmax was slightly higher in people with CF after a single dose. Rifampin PK parameters were altered in persons with CF. Addition of food and enzymes in CF subjects did not improve PK parameters. Standard dosing guidelines should be used as a starting point for people with CF initiating MAC therapy and therapeutic drug monitoring should be routinely performed to prevent the possibility of treatment failure due to abnormal drug concentrations.

Abstract
ABSTRACT We report the clinical results and problems of combined administration of rifampicin, ethambutol, and clarithromycin (REC) for the treatment of Mycobacterium avium complex (MAC) infection of the hand (hand MAC).Participants included 7 patients with hand MAC. After resection of the infected lesion, REC was prescribed for 12 months. For these patients, the site of infection, clinical course after initiation of REC, adverse drug effects (ADEs), and incidence of recurrence were evaluated.Sites of infection were the flexor tenosynovium in 5 patients, extensor tenosynovium in 1 patient, and both flexor and extensor tenosynovium in 1 patient. ADEs of REC occurred in 5 patients, and included visual disturbance caused by ethambutol in 2 patients, liver function abnormality caused by rifampicin in 2 patients, and fever with diarrhea caused by rifampicin in 1 patient. For 2 of these 5 patients, desensitization therapy was applied and REC was able to be reinstated. In the remaining 3 patients, the causative drugs were discontinued and levofloxacin, a new quinolone, was administered. Complete healing was achieved in 5 patients, and recurrence was observed in 2 patients. These 2 patients with recurrence included 1 patient in whom REC was completed and 1 patient in whom REC therapy was modified due to ADE.REC provided relatively good clinical results as a treatment for hand MAC. However, recurrences were observed even after the completion of REC and the use of an alternative drug. Optimal duration of REC and appropriate alternative drugs need to be identified in the future.

Abstract
We aimed to investigate the effect of interval between food intake and drug administration at fasting condition on the plasma concentrations of first-line anti- tuberculosis (TB) drugs in Chinese population. Newly diagnosed TB patients administered the anti-TB drugs under fasting conditions orally, and then had prepared breakfast at 30 minutes and 120 min after dosing, respectively. Blood sampling was also performed 120 minutes after dosing for the detection of Cmax purpose. Overall, twenty-five participants were included in our analysis. The Cmaxs of 30 minutes interval and 120 minutes interval were 21.8 ± 2.0 and 19.2 ± 2.0 μg/mL for rifampin, 1.6 ± 0.2 and 2.1 ± 0.2 μg/mL for isoniazid (INH), 1.5 ± 0.1and 1.5 ± 0.2 μg/mL for ethambutol (EMB), and 49.2 ± 3.7 and 41.5 ± 3.9 μg/mL for pyrazinamide, respectively. Statistical analysis revealed that there was no statistical difference between 2 groups. Additionally, 88.0% and 72.0% of the 25 participants at 2-hour interval group had peak concentrations less than the lower limit of the reference range for INH and EMB, respectively. The Cmaxs of INH were 0.9 ± 0.4 μg/ml for rapid acetylator, which was significantly lower than those of intermediate (1.4 ± 1.0 μg/mL), and slow acetylator (2.5 ± 1.0 μg/mL), respectively (P < .01). In conclusion, our data demonstrate that early food intake at 30 minutes after drug administration had no significant influence on the plasma concentrations. In addition, a high proportion of patients receiving first-line anti-TB regimen fail to achieve the expected plasma drug ranges of INH and EMB (P > .05).

Abstract
BACKGROUND To address the multifaceted challenges associated with tuberculosis (TB) in-person directly observed therapy (DOT), the World Health Organization recently recommended that countries maximize the use of digital adherence technologies. Sub-Saharan Africa needs to investigate the effectiveness of such technologies in local contexts and proactively contribute to global decisions around patient-centered TB care. This study aims to evaluate the effectiveness of pillbox-enabled self-administered therapy (SAT) compared to standard DOT on adherence to TB medication and treatment outcomes in Ethiopia. It also aims to assess the usability, acceptability, and cost-effectiveness of the intervention from the patient and provider perspectives. METHODS This is a multicenter, randomized, controlled, open-label, superiority, effectiveness-implementation hybrid, mixed-methods, two-arm trial. The study is designed to enroll 144 outpatients with new or previously treated, bacteriologically confirmed, drug-sensitive pulmonary TB who are eligible to start the standard 6-month first-line anti-TB regimen. Participants in the intervention arm (n = 72) will receive 15 days of HRZE-isoniazid, rifampicin, pyrazinamide, and ethambutol-fixed-dose combination therapy in the evriMED500 medication event reminder monitor device for self-administration. When returned, providers will count any remaining tablets in the device, download the pill-taking data, and refill based on preset criteria. Participants can consult the provider in cases of illness or adverse events outside of scheduled visits. Providers will handle participants in the control arm (n = 72) according to the standard in-person DOT. Both arms will be followed up throughout the 2-month intensive phase. The primary outcomes will be medication adherence and sputum conversion. Adherence to medication will be calculated as the proportion of patients who missed doses in the intervention (pill count) versus DOT (direct observation) arms, confirmed further by IsoScreen urine isoniazid test and a self-report of adherence on eight-item Morisky Medication Adherence Scale. Sputum conversion is defined as the proportion of patients with smear conversion following the intensive phase in intervention versus DOT arms, confirmed further by pre-post intensive phase BACTEC MGIT TB liquid culture. Pre-post treatment MGIT drug susceptibility testing will determine whether resistance to anti-TB drugs could have impacted culture conversion. Secondary outcomes will include other clinical outcomes (treatment not completed, death, or loss to follow-up), cost-effectiveness-individual and societal costs with quality-adjusted life years-and acceptability and usability of the intervention by patients and providers. DISCUSSION This study will be the first in Ethiopia, and of the first three in sub-Saharan Africa, to determine whether electronic pillbox-enabled SAT improves adherence to TB medication and treatment outcomes, all without affecting the inherent dignity and economic wellbeing of patients with TB.

Abstract
INTRODUCTION Shorter duration of treatment for the management of drug-susceptible pulmonary tuberculosis (TB) would be a significant improvement in the care of patients suffering from the disease. Besides newer drugs and regimens, other modalities like host-directed therapy are also being suggested to reach this goal. This study's objective is to assess the efficacy and safety of metformin-containing anti-TB treatment (ATT) regimen in comparison to the standard 6-month ATT regimen in the treatment of patients with newly diagnosed sputum smear-positive drug-sensitive pulmonary TB. METHODS AND ANALYSIS We are conducting a multicentric, randomised open-label controlled clinical trial to achieve the study objective. The intervention group will receive isoniazid (H), rifampicin (R), ethambutol (E) and pyrazinamide (Z) along with 1000 mg of daily metformin (Met) for the first 2 months while the control group will receive only HRZE. After 2 months, both the groups will receive HRE daily for 4 months. The primary endpoint is time to sputum culture conversion. Secondary endpoints will include time to detection of Mycobacterium tuberculosis in sputum, pharmacokinetics and pharmacogenomics of study drugs, drug-drug interactions, safety and tolerability of the various combinations and measurement of autophagy and immune responses in the study participants. ETHICS AND DISSEMINATION The ethics committee of the participating institutes have approved the study. Results from this trial will contribute to evidence towards constructing a shorter, effective and safe regimen for patients with TB. The results will be shared widely with the National Programme managers, policymakers and stakeholders through open access publications, dissemination meetings, conference abstracts and policy briefs. This is expected to provide a new standard of care for drug-sensitive patients with pulmonary TB who will not only reduce the number of clinic visits and lost to follow-up of patients from treatment but also reduce the burden on the healthcare system.

Abstract
Background Resistance to isoniazid is the most common form of drug-resistance in tuberculosis. However only a tiny proportion of TB patients in the world have access to isoniazid drug susceptibility testing—the widely implemented Xpert MTB/RIF technology only tests for resistance to rifampicin. Patients with isoniazid mono resistance that is not identified at baseline are treated with a standard regimen that effectively results in rifampicin mono-therapy during the latter four months of the six month treatment course, exposing remaining viable organisms to a single agent and greatly increasing the risk of development of multi drug-resistant TB. Unusually, Peru has pioneered universal pre-treatment drug susceptibility testing with methods that identify isoniazid resistance and has thus identified a large number of individuals requiring tailored therapy. Since 2010, treatment in Peru for isoniazid-resistant tuberculosis without multidrug-resistant tuberculosis (Hr-TB) has been with a standardized nine-month regimen of levofloxacin, rifampicin, ethambutol and pyrazinamide. The objectives of this study were to evaluate the outcomes of treatment for patients with Hr-TB initiating treatment with this regimen between January 2012 and December 2014 and to determine factors affecting these outcomes. Methods Retrospective cross-sectional study; case data were obtained from the national registry of drug-resistant tuberculosis. Patients diagnosed with isoniazid resistant TB without resistance to rifampicin, pyrazinamide, ethambutol and quinolones as determined by either a rapid drug susceptibility testing (DST) (nitrate reductase test, MODS, Genotype MTBDRplus) or by the proportion method were included. Findings A total of 947 cases were evaluated (a further 403 without treatment end date were excluded), with treatment success in 77.2% (731 cases), loss to follow-up in 19.7% (186 cases), treatment failure in 1.2% (12 cases), and death in 1.9% (18 cases). Unfavorable outcomes were associated in multivariate analysis with male gender (OR 0.50, 95% CI 0.34–0.72, p<0.05), lack of rapid DST (OR 0.67, 95% CI 0.50–0.91, p = 0.01), additional use of an injectable second-line anti-tuberculous drug (OR 0.46, 95% CI 0.31–0.70, p<0.05), and treatment initiation in 2014 (OR 0.77, 95% CI 0.62–0.94, p = 0.01). Interpretation The treatment regimen implemented in Peru for isoniazid resistant TB is effective for TB cure and is not improved by addition of an injectable second-line agent. Access to rapid DST and treatment adherence need to be strengthened to increase favorable results.

Abstract
Objectives To evaluate, through (OCT), alterations in retinal thickness, secondary to use of ethambutol in the treatment of patients with tuberculosis. In addition to studying the use of simpler semiological tools, such as Amsler and Ishihara, in the screening of these cases. Methods Thirty patients with ethambutol were recruited from the reference service of tuberculosis treatment at the Federal University of Espírito Santo from May 2015 to July 2016. After clinical history, the following parameters were analyzed; best corrected visual acuity, biomicroscopy, tonometry, photomotor reflex testing, Ishihara test, Amsler’s grid test, color digital retinography and optical coherence tomography with CIRRUS HD-OCT (Humphrey-Zeiss) every 2 months during treatment with ethambutol. They were divided into two groups according to the treatment: (1) standard group, two months of ethambutol; (2) extended group, nine to twelve months of ethambutol. Results There was a significant reduction in OCT thickness between the pre and post treatment times in ten eyes of the extended group, mean reduction of 7,8 microns and in seven eyes of the standard group, with an average of 5.57 microns. During the study, a significant reduction of retinal thickness was observed in both groups at two months of treatment, and the delta percentage was higher in those patients who presented reduction of visual acuity and / or change in the Ishihara test. Conclusion There was a significant reduction in the thickness of the nerve fiber layer by OCT in the patients studied, being more pronounced in those submitted to the extended treatment regimen. This reduction was observed two months after the start of therapy, and was more significant in the cases that presented changes in the Ishihara test.

Abstract
Human bovine tuberculosis is a rare zoonotic infection in developed countries which has been achieved predominantly by effective eradication programmes in cattle. The principal modes of transmission are consumption of unpasteurised dairy products and close contact with infected cattle. The clinical and radiological presentation is indistinguishable from tuberculosis caused by Mycobacterium tuberculosis The diagnosis should be considered in individuals with relevant risk factors who present with intra/extrathoracic pathology. We describe and discuss a case of bovine tuberculosis with a synchronous primary bronchus carcinoma in an immunocompetent individual who presented with a solitary pulmonary nodule and contralateral mediastinal lymphadenopathy on CT imaging. The diagnosis of M. bovis infectionwas aided by 18F-fluorodeoxyglucose positron emission tomography/CT imaging and endobronchial ultrasound-guided mediastinal lymph node sampling.

Abstract
RATIONALE Ulcerative skin tuberculosis (TB) is a rare form of extrapulmonary TB. CASE REPORT We present a case of a 65-year-old patient with perianal ulcer, which had been present for 1 year. Anamnesis revealed he had been persistently coughing for the same period of time. Histological examination of perianal skin showed necrotizing granulomatous lesions, acid-fast staining in sputum samples was ++++, TB antibody in the blood was positive, TB DNA test was positive, and chest scan that showed secondary pulmonary TB accompanied by possible pulmonary cavity formation in the 2 upper lungs. INTERVENTIONS Anti-TB therapy with isoniazid, rifampicin, ethambutol, and pyrazinamide for 6 months. The skin ulcer completely healed after 6 months. CONCLUSION TB should be suspected for nonhealing ulcers. Pertinent studies should be done early during the lesion; finally, TB treatment should be initiated immediately after diagnosis is made.

Abstract
RATIONALE Unilateral hypoplasia of the lung is a rare congenital condition, the mechanism of which is poorly understood. Primary pulmonary hypoplasia occurring in an adult is extremely rare and we present what is probably the first case of a link to a tuberculous pleural effusion in a young woman after childbirth. PATIENT CONCERNS Herein, we describe a 31-year-old woman with left lung hypoplasia, and she not only survived to adulthood without problems, but was able to deliver a baby in natural labor. DIAGNOSES Left lung hypoplasia, right tuberculous pleural effusion. INTERVENTIONS We initiated an anti-tuberculosis treatment for this patient with dose adjustments to her weight of isoniazid (0.3 g/day), rifampicin (0.45 g/day), pyrazinamide (1.5 g/day), and ethambutol (0.75 g/day) for 2 months then isoniazid and rifampicin for another 4 months. OUTCOMES Ten days later after beginning therapy, she became afebrile and the pleural effusion resolved. No recurrence was observed during a 6-month follow-up period. LESSONS In clinical practice, if one sees a chest x-ray revealing complete or incomplete opacification of a hemithorax with volume loss and history of repeated respiratory infections, one should consider the possibility of unilateral pulmonary hypoplasia. In such cases, regular close follow-up is important to minimize infections and to prevent development of cor pulmonale or respiratory failure.

Abstract
Tuberculosis (TB) is a bacterial disease responsible for millions of infections and preventable deaths each year. Its treatment is complicated by patients' noncompliance due to dosing frequency, lengthy treatment, and adverse side effects associated with current chemotherapy. However, no modifications to the half-a-century old standard chemotherapy have been made based on a nanoformulation strategy to improve pharmacokinetic efficacy. In this study, we have designed a new nanodelivery formulation, using graphene oxide as the nanocarrier, loaded with the anti-TB antibiotic, ethambutol. The designed formulation was characterized using a number of molecular analytical techniques. It was found that sustained release of the drug resulted in better bioavailability. In addition, the designed formulation demonstrated high biocompatibility with mouse fibroblast cells. The anti-TB activity of the nanodelivery formulation was determined using whole-cell resazurin microtiter plate assay, modified-spot culture growth inhibition assay, and biofilm inhibition assay. The nanodelivery formulation showed good anti-mycobacterial activity. The anti-mycobacterial activity of Ethambutol was unaffected by the drug loading and release process. The results of this study demonstrated the potential of this new nanodelivery formulation strategy to be considered for modifying existing chemotherapy to yield more efficacious antibiotic treatment against TB.

Abstract
OBJECTIVE To study the efficacy and tolerability of Risorine Capsule (A fixed dose combination of Rifampicin 200 mg + INH 300 mg + Piperine 10 mg) therapy in the treatment of drug-susceptible pulmonary tuberculosis patients who developed GI intolerance with standard WHO anti TB regimen. METHODS 33 patients with pulmonary tuberculosis were treated with one Risorine kit, daily consisting of one capsule of Risorine, one tablet of ethambutol (800 mg) and two tablets of Pyrazinamide 750 mg each, for first two months of therapy. All the patients received one capsule of Risorine daily for next four months. Symptomatic improvement, Sputum conversion and radiological improvement were monitored at regular intervals. RESULTS Out of 27 patients who were sputum positive at baseline, 24 patients became sputum negative during the first two months of treatment. Out remaining three patients, one became sputum negative at the end of third month of treatment and the other two became sputum negative at the end of sixth month of treatment. Out of 33 patients, only two patients developed mild nausea, which subsided spontaneously. One patient who was HIV positive, developed hepatitis. CONCLUSIONS Risorine, a novel formulation of rifampicin 200 mg with bioenhancer piperine 10mg, is found to be highly effective and well tolerated in the treatment of drug - susceptible pulmonary tuberculosis.

Abstract
BACKGROUND Tuberculosis (TB) of the gastrointestinal tract and any other organ within the abdominal cavity is abdominal TB, and most guidelines recommend the same six-month regimen used for pulmonary TB for people with this diagnosis. However, some physicians are concerned whether a six-month treatment regimen is long enough to prevent relapse of the disease, particularly in people with gastrointestinal TB, which may sometimes cause antituberculous drugs to be poorly absorbed. On the other hand, longer regimens are associated with poor adherence, which could increase relapse, contribute to drug resistance developing, and increase costs to patients and health providers. OBJECTIVES To compare six-month versus longer drug regimens to treat people that have abdominal TB. SEARCH METHODS We searched the following electronic databases up to 2 September 2016: the Cochrane Infectious Diseases Group Specialized Register, the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, Embase (accessed via OvidSP), LILACS, INDMED, and the South Asian Database of Controlled Clinical Trials. We searched the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) and ClinicalTrials.gov for ongoing trials. We also checked article reference lists. SELECTION CRITERIA We included randomized controlled trials (RCTs) that compared six-month regimens versus longer regimens that consisted of isoniazid, rifampicin, pyrazinamide, and ethambutol to treat adults and children that had abdominal TB. The primary outcomes were relapse, with a minimum of six-month follow-up after completion of antituberculous treatment (ATT), and clinical cure at the end of ATT. DATA COLLECTION AND ANALYSIS Two review authors independently selected trials, extracted data, and assessed the risk of bias in the included trials. For analysis of dichotomous outcomes, we used risk ratios (RR) with 95% confidence intervals (CIs). Where appropriate, we pooled data from the included trials in meta-analyses. We assessed the quality of the evidence using the GRADE approach. MAIN RESULTS We included three RCTs, with 328 participants, that compared six-month regimens with nine-month regimens to treat adults with intestinal and peritoneal TB. All trials were conducted in Asia, and excluded people with HIV, those with co-morbidities and those who had received ATT in the previous five years. Antituberculous regimens were based on isoniazid, rifampicin, pyrazinamide, and ethambutol, and these drugs were administered daily or thrice weekly under a directly observed therapy programme. The median duration of follow-up after completion of treatment was between 12 and 39 months.Relapse was uncommon, with two cases among 140 participants treated for six months, and no events among 129 participants treated for nine months. The small number of participants means we do not know whether or not there is a difference in risk of relapse between the two regimens (very low quality evidence). At the end of therapy, there was probably no difference in the proportion of participants that achieved clinical cure between six-month and nine-month regimens (RR 1.02, 95% CI 0.97 to 1.08; 294 participants, 3 trials, moderate quality evidence). For death, there were 2/150 (1.3%) in the six-month group and 4/144 (2.8%) in the nine-month group. All deaths occurred in the first four months of treatment, so was not linked to the duration of treatment in the included trials. Similarly, the number of participants that defaulted from treatment was small in both groups, and there may be no difference between them (RR 0.50, 95% CI 0.10 to 2.59; 294 participants, 3 trials, low quality evidence). Only one trial reported on adherence to treatment, with only one participant allocated to the nine-month regimen presenting poor adherence to treatment. We do not know whether six-month regimens are associated with fewer people experiencing adverse events that lead to treatment interruption (RR 0.53, 95% CI 0.18 to 1.55; 318 participants, 3 trials, very low quality evidence). AUTHORS' CONCLUSIONS We found no evidence to suggest that six-month treatment regimens are inadequate for treating people that have intestinal and peritoneal TB, but numbers are small. We did not find any incremental benefits of nine-month regimens regarding relapse at the end of follow-up, or clinical cure at the end of therapy, but our confidence in the relapse estimate is very low because of size of the trials. Further research is required to make confident conclusions regarding the safety of six-month treatment for people with abdominal TB. Larger studies that include HIV-positive people, with long follow-up for detecting relapse with reliability, would help improve our knowledge around this therapeutic question.

Abstract
Breast tuberculosis (TB) is rare form of extra-pulmonary TB. It is most commonly seen in women of reproductive age group, especially in young, multiparous women who are breast feeding. In geriatric women, breast TB in some cases simulates with breast carcinoma due to common signs which include hard breast lump with nodular surface, ulceration, fixity to skin, discharging sinus, retraction of nipple, axillary lymphadenopathy etc. Hence, it is very difficult to differentiate breast TB from breast cancer, especially in elderly women on clinical ground only, and therefore, histopathological diagnosis is mandatory. Fine needle aspiration cytology is frequently inconclusive due to very small amount of tissue material, and open biopsy or lumpectomy followed by histopathological examination is necessary to confirm the diagnosis of breast TB. Six-month course of anti-tuberculous therapy - ATT (rifampicin, isoniazid, pyrazinamide and ethambutol) is adequate for complete resolution. Here, we report a case of breast TB in an elderly women presenting with left sided breast lump with ulceration of overlying skin and ipsilateral axillary lymphadenopathy. This case of tuberculous mastitis was suspected to be carcinoma due to presence of hard, tender, breast lump with irregular margin, nodular surface, ulceration, purulent discharge and ipsilateral axillary lymphadenopathy in absence of any constitutional symptoms of TB, and heterogenous, hypoechoic mass on USG, which was confirmed by histopathological examination of resected breast lump and responded fully to ATT.

Abstract
An 89-year-old man presented with an inflammatory erythematous plaque on the left thigh that closely mimicked cellulitis. Empiric therapies with ordinary antibiotics were not effective. A skin biopsy showed epithelioid cell granulomas throughout the dermis and subcutis. Ziehl-Neelsen stain revealed numerous acid-fast bacilli. Additionally, Mycobacterium tuberculosis was isolated from a skin biopsy specimen as well as gastric fluid and sputum cultures. He was diagnosed with tuberculous cellulitis with pulmonary tuberculosis. Cellulitis is a common disease seen by dermatologists; however, sometimes other diseases may masquerade as this banal illness. Among them, cutaneous tuberculosis should be excluded because of its clinical significance. Most cases of cutaneous tuberculosis are symptom free, but tuberculous cellulitis is sometimes painful. Therefore, cutaneous tuberculosis should always be considered in the differential diagnosis of a cellulitislike rash if the lesions do not respond to ordinary antibiotic therapy, especially in countries with a high incidence of tuberculosis.

Abstract
The proportion of the elderly in patients with pulmonary tuberculosis is increasing, and failure to complete the standard treatment regimen is not uncommon in these patients. We examined the compliance rate and prob- lems of the standard regimen in the late elderly pulmonary tuberculosis patients. [Methods] We reviewed the medical records of late elderly patients with pulmonary tuberculosis aged 75 or above who were smear-positive and treated in Kanagawa Cardiovascular and Respiratory Center between January 2011 and December 2014. Our retrospective study examined patient characteris- tics, imaging findings, laboratory results, and outcomes. The compliance rate of standard regimen during the hospitaliza- tion period was calculated. We compared the discontinua- tion rate and the incidence of adverse drug reactions by body weight equivalent doses of anti-tuberculosis drugs. [Results] A total of 298 patients were included in this study, and 76% of those patients were aged 80 or above. Anti-tuberculosis therapy was not able to be initiated for 3 patients (1%), and treatment other than standard regimen was inevitably introduced at initiation in 21 patients. The remaining 274 patients (92%) were administered the stan- dard regimen. Among them, at least one medication was subsequently discontinued for 85 patients (29%), and the medication was changed due to drug resistance in 6 patients . (2%). The remaining 183 patients (61%) complied with the standard regimen during hospitalization. In the comparison by body weight equivalent dose, significantly more patients discontinued their medication in the group using ethambutol with a higher standard dose per weight (37% vs. 21%, p=0.02). [Conclusion] Nearly 40% of the late elderly patients could not comply with the standard regimen. We may need to be more careful when calculating ethambutol equivalent dose.

Abstract
An 86-year-old woman with severe dementia had been treated with oral prednisolone at 2 mg/day for autoimmune bullous dermatosis for several years. One year ago, she referred to our hospital due to an ulcerative skin lesion over the right tibial tuberosity. The lesion was treated by an iodine-containing ointment, but did not heal. Subsequently, a new skin lesion appeared in the right popliteal fossa. One month ago, the patient had increased sputum production that was accompanied by fever, anorexia, and dyspnea; consequently, she visited our department. Chest computed tomography revealed diffuse micronodules with ground-glass attenuation. Acid-fast bacteria staining of the sputum was positive and the polymerase chain reaction detected Mycobacterium tuberculosis. In addition, the bacilli were also found in the skin lesions of the right limb. Therefore, a diagnosis of cutaneous, and miliary tuberculosis was made. Although the anti-tuberculous combination chemotherapy consisting of isoniazid, rifampicin, and ethambutol was immediately initiated, her condition did not improve. She died on day 19 of hospitalization. Drug susceptibility testing revealed no resistance to all the three drugs; hence, it was concluded that the time-delay in diagnosis of cutaneous tuberculosis lead to the progression to miliary tuberculosis and subsequent death.

Abstract
INTRODUCTION Tuberculosis is still one of the most important health problems in developing countries and increasing drug resistance is the main concern for its treatment. This study was designed to characterize the drug resistant Mycobacterium tuberculosis isolated from patients suffering from pulmonary tuberculosis in northeast of Iran. METHOD In this cross-sectional study during 2012-2013, drug susceptibility testing was performed on Mycobacterium tuberculosis isolated in northeast of Iran using proportional method. Epidemiological data concerning these strains were also analyzed. RESULTS Among 125 studied isolates, 25 mycobacteria (20%) were diagnosed as nontuberculosis mycobacteria. Among the remaining 100 Mycobacterium tuberculosis isolates, the resistance rates were 7%, 7%, 3%, and 9% against isoniazid, rifampin, ethambutol, and streptomycin, respectively. Four isolates were resistant against both isoniazid and rifampin (MDR tuberculosis). The highest resistance rate was observed among 15-45-year-old patients. The MDR tuberculosis was much more prevalent among those who had previous history of treatment. CONCLUSION Considering these findings, DOTS strategy should be emphasized and promptly used in order to prevent further resistance. Regarding the high rate of nontuberculosis mycobacteria, it is recommended that confirmatory tests were performed before any therapeutic decision.

Abstract
BACKGROUND The available pharmacokinetic data on anti-tubercular drugs in children raises the concern of suboptimal plasma concentrations attained when doses extrapolated from adult studies are used. Also, there is lack of consensus regarding the effect of malnutrition on pharmacokinetics of anti-tubercular drugs in children. We conducted this study with the aims of determining the plasma concentrations of isoniazid, rifampicin, pyrazinamide and ethambutol achieved with different dosage of the anti-tubercular drugs so as to provide supportive evidence to the revised dosages and to evaluate the effects of malnutrition on the pharmacokinetics of these drugs in children. We also attempted to correlate the plasma concentrations of these drugs with clinical outcome of therapy. METHOD Prospective drug estimation study was conducted in two groups of children, age 6 months to 15 years, with tuberculosis, with or without severe malnutrition, receiving different dosage of daily anti- tubercular therapy. The dosage (range) of isoniazid was 5 (4-6) and 10 (7-15) mg/kg in the two groups, respectively, that of rifampicin-10 (8-12) and 15 (10-12) mg/kg, respectively, both the groups received same dose of pyrazinamide (30-35 mg/kg) and ethambutol (20-25 mg/kg). All four drugs were simultaneously estimated by liquid chromatography-mass spectrometry (LC-MS/MS). RESULTS AND CONCLUSION The median (IQR) Cmax of isoniazid increased significantly from 0.6 (0.3,1.2) μg/mL to 3.4 (1.8, 5.0) μg/mL with increase in the dose. Plasma rifampicin concentrations increased only marginally on increasing the dose [median (IQR) Cmax: 10.4 (7.2, 13.9) μg/mL vs. 12.0 (6.1, 24.3) μg/mL, p=0.08]. For ethambutol, 55.9% of the children had inadequate 2-hour concentrations. Two-hour plasma concentrations of at least one drug were low in 59 (92.2%) and 54 (85.7%) children in the two dosing regimen, respectively. We did not observe any effect of malnutrition on pharmacokinetic parameters of the drugs studied. We did not observe an association between low plasma drug concentrations and poor outcome. We may have to be cautious while increasing the doses and strive to asses other factors influencing the drug concentrations and treatment outcomes in children.

Abstract
A case of primary gingival tuberculosis in a 71-year-old Japanese woman is herein presented. A serous saliva culture was positive for tuberculosis, and we recognized that the origin of the tuberculosis infection was the gingiva based on the genetic identification in gingival biopsy tissue. The definitive diagnosis was facilitated by the genetic identification, a useful modern tool for diagnosing infectious diseases. The location and clinical presentation of this lesion were unusual, which underlines the importance of considering tuberculosis in the differential diagnosis of oral lesions that affect the gingiva.

Abstract
BACKGROUND Micronutrients play an important role in immune function. To our knowledge, there have been no comprehensive studies on the role of micronutrient supplementation in children with tuberculosis. OBJECTIVE We assessed the effect of micronutrient supplementation in children treated with antituberculosis therapy (ATT). DESIGN A randomized, double-blind, placebo-controlled trial that used a 2 × 2 factorial design was undertaken at 2 teaching hospitals in Delhi. Children with newly diagnosed intrathoracic tuberculosis were enrolled, and they received ATT together with daily supplementation for 6 mo with either zinc alone, micronutrients without zinc, micronutrients in combination with zinc, or a placebo. Main outcomes were weight gain and an improvement in a chest X-ray (CXR) lesion assessed at 6 mo of treatment. RESULTS A total of 403 children were enrolled and randomly assigned. A microbiological diagnosis of tuberculosis was confirmed in 179 children (44.4%). The median (95% CI) increase in weight-for-age z score at 6 mo was not significantly different between subjects who received micronutrients [0.75 (0.66, 0.84)] and those who did not receive micronutrients [0.76 (0.67, 0.85)] and between subjects who received zinc [0.76 (0.68, 0.85)] and those who did not receive zinc [0.75 (0.66, 0.83)]. An improvement in CXR was observed in 285 children, but there was no difference between those receiving zinc and no zinc or between those receiving micronutrients and no micronutrients after 6 mo of ATT. However, children who received micronutrients had a faster gain in height over 6 mo than did those who did not receive micronutrients (height-for-age z score Δ = 0.08; P = 0.014). CONCLUSIONS Micronutrient supplementation did not modify the weight gain or clearance of lesions on CXR in children with intrathoracic tuberculosis. However, micronutrient supplementation during treatment may improve height gain in children with intrathoracic tuberculosis. This trial was registered at clinicaltrials.gov as NCT00801606.

Abstract
BACKGROUND In contrast to drug-sensitive tuberculosis, the guidelines for the treatment of multi-drug-resistant tuberculosis (MDR-TB) have a very poor evidence base; current recommendations, based on expert opinion, are that patients should be treated for a minimum of 20 months. A series of cohort studies conducted in Bangladesh identified a nine-month regimen with very promising results. There is a need to evaluate this regimen in comparison with the currently recommended regimen in a randomized controlled trial in a variety of settings, including patients with HIV-coinfection. METHODS/DESIGN STREAM is a multi-centre randomized trial of non-inferiority design comparing a nine-month regimen to the treatment currently recommended by the World Health Organization in patients with MDR pulmonary TB with no evidence on line probe assay of fluoroquinolone or kanamycin resistance. The nine-month regimen includes clofazimine and high-dose moxifloxacin and can be extended to 11 months in the event of delay in smear conversion. The primary outcome is based on the bacteriological status of the patients at 27 months post-randomization. Based on the assumption that the nine-month regimen will be slightly more effective than the control regimen and, given a 10% margin of non-inferiority, a total of 400 patients are required to be enrolled. Health economics data are being collected on all patients in selected sites. DISCUSSION The results from the study in Bangladesh and cohorts in progress elsewhere are encouraging, but for this regimen to be recommended more widely than in a research setting, robust evidence is needed from a randomized clinical trial. Results from the STREAM trial together with data from ongoing cohorts should provide the evidence necessary to revise current recommendations for the treatment for MDR-TB. TRIAL REGISTRATION This trial was registered with clincaltrials.gov (registration number: ISRCTN78372190) on 14 October 2010.

Abstract
Disseminated mycobacterium avium complex (MAC) causing protein-losing enteropathy (PLE) due to intestinal lymphangiectasia (IL) in a non-HIV immunocompromised state is extremely rare. We present a case of 56-year-old male who was evaluated for worsening dyspnea and found to have right-sided chylous pleural effusion as well as worsening abdominal and retroperitoneal lymphadenopathy. He had a history of psoriasis for which hewas on etanercept and alefacept which were stopped two years prior to the presentation. The evaluation revealed a MAC infection in his lymph nodes--a low CD4 count but negative for HIV. He was started on MAC therapy. He subsequently developed noninfectious diarrhea, Hypoalbuminemia, recurrentpleural effusions, ascites, and Pneumocystis jiroveci pneumonia (PJP). Despite appropriate antibiotics and management--including total parental nutrition (TPN) with a medium-chain triglyceride enriched low fat diet--the patient's clinical condition deteriorated rapidly resulting in death.

Abstract
Tuberculosis of the cervix is a rare disease and accounts for 0.1-0.65% of all cases of tuberculosis. We present an unusual case of a 57 years old female who presented with chief complaints of Serosaguineous vaginal discharge of one year duration and irregular firm cervix with contact bleeding and was clinically diagnosed to have cervical cancer. Histopathology revealed typical findings of cervical tuberculosis. Cervical tuberculosis should be considered as a differential diagnosis of cervical malignancy. The clinical presentation and diagnosis of cervical tuberculosis is reviewed.

Abstract
Tuberculosis (TB) is the most common cause of cervical lymphadenopathy in the TB-endemic zone, like India but it can also mimic other diseases. Four cases of cervical lymphadenopathy presented to us as initial treatment failure after completion of six months of antitubercular drugs (ATD), including rifampicin, isoniazid, pyrazinamide, and ethambutol. All were diagnosed as having tuberculosis either by fine needle aspiration cytology or clinically from outside our institution. In one case, tuberculosis was the final diagnosis but, unfortunately, it was multidrug-resistant. In other three cases, Hodgkin disease, Non-Hodgkin lymphoma, and Kikuchi's disease were the diagnoses. In resource-poor countries, like India, which is also a TB-endemic zone, TB should be the first diagnosis in all cases of chronic cervical lymphadenopathy, based on clinical and/or cytological evidences. So, they were correctly advised antitubercular therapy (ATT) initially. Sometimes, TB mimics other aetiologies where apparent initial improvement with ATT finally results in treatment failure. Hence, investigations for microbiological and histopathological diagnosis are warranted, depending on the resources and feasibility. If these tests are not routinely available, the patients should be under close monitoring so that lymphoma, drug-resistant TB, or other aetiologies of cervical lymphadenopathy are not missed. Patients with cervical lymphadenopathy rarely presents acutely; so, a physician can take the opportunity of histopathological study of lymphnode tissue.

Abstract
Esophageal anthracosis with tuberculous lymphadenitis is a very rare disease. Almost all reported cases are diagnosed using multiple endoscopic biopsies or thoracic esophagectomy. The present case report describes a case of esophageal anthracosis with tuberculous lymphadenitis that was diagnosed using transesophageal endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) alone. After taking antituberculosis drugs, the patient's chest pain was relieved and she recovered. The patient achieved an excellent outcome following the use of less invasive methods than mediastinoscopy. If no esophageal anthracotic lesions are found on the mucous membrane layer of the esophagus, transesophageal endoscopic ultrasound-guided fine-needle aspiration is a suitable approach for diagnosing esophageal anthracosis.

Abstract
Multiple drug allergy (MDA) is characterized by hypersensitivity to 2 or more chemically unrelated drugs. Multiple drug allergy from simultaneous use of antituberculosis drugs is a rare phenomenon that mainly presents as an urticarial or maculopapular eruption. This case report describes a 58-year-old man who developed a generalized eczematous eruption during the sixth week of oral therapy with 4 antituberculosis drugs-isoniazid, ethambutol, rifampicin, and morphazinamide-for treatment of suspected pleural tuberculosis. The eruption resolved after treatment with systemic corticosteroids and cessation of isoniazid and ethambutol. During a lesion-free period 6 months after cessation of the corticosteroids, patch testing with serial dilutions of isoniazid and ethambutol revealed positive reactions; irritant patch test reactions were excluded by testing with graded concentrations of each drug. The patient avoided the causative drugs and reported no new eruptions at 1-year follow-up. It is important for dermatologists to consider the value of patch testing in determining the causative drugs in suspected cases of eczematous-type MDA.

Abstract
Background The optimal duration of preventive therapy for tuberculosis (TB) among HIV-infected persons in TB-endemic countries is unknown. Methods An open-label randomized clinical trial was performed and analyzed for equivalence. Seven hundred and twelve HIV-infected, ART-naïve patients without active TB were randomized to receive either ethambutol 800 mg and isoniazid 300 mg daily for six-months (6EH) or isoniazid 300 mg daily for 36-months (36H). Drugs were dispensed fortnightly and adherence checked by home visits. Patients had chest radiograph, sputum smear and culture performed every six months, in addition to investigations if they developed symptoms. The primary endpoint was incident TB while secondary endpoints were all-cause mortality and adverse events. Survival analysis was performed on the modified intent to treat population (m-ITT) and rates compared. Findings Tuberculosis developed in 22 (6.4%) of 344 subjects in the 6EH arm and 13 (3.8%) of 339 subjects in the 36H arm with incidence rates of 2.4/100py (95%CI- 1.4–3.5) and 1.6/100py (95% CI-0.8–3.0) with an adjusted rate ratio (aIRR) of 1.6 (0.8–3.2). Among TST-positive subjects, the aIRR of 6EH was 1.7 (0.6–4.3) compared to 36H, p = 0.8. All-cause mortality and toxicity were similar in the two arms. Among 15 patients with confirmed TB, 4 isolates were resistant to isoniazid and 2 were multidrug-resistant. Interpretation Both regimens were similarly effective in preventing TB, when compared to historical incidence rates. However, there was a trend to lower TB incidence with 36H. There was no increase in isoniazid resistance compared to the expected rate in HIV-infected patients. The trial is registered at ClinicalTrials.gov, NCT00351702.

Abstract
UNLABELLED Medicaton used to treat tuberculosis is responsible for numerous side effects that have a major impact on patient's health, with a negative influence on the quality of life. Patients of all ages must be trained in order to recognize all the adverse effects and the undesirable reactions produced by antituberculosis medication. We report the case of a 24-year-old woman with generalized psoriasis and psoriatic arthropathy who was treated against tuberculosis. After 7 days of treatment with isoniazid, rifampicin, ethambutol and pyrazinamid she had severe allergic reaction with generalized pruritus and rash which were difficult to control with antiallergic treatment. CONCLUSIONS Particular to this case is the absence in patient's history of the allergic reactions to medication. The re-establishment of treatment of tuberculosis was done by clinical trials and the patient had responded to only three drugs: isoniazid, rifampicin and ofloxacin, so the patient received an individual treatment due to adverse reactions to tuberculosis medications.

Abstract
The outcomes of directly observed therapy of tuberculosis (DOT) between 1/1/1979 and 12/31/2009 were analyzed. Results obtained in the 1979-1999 period were compared with those achieved in the 2000-2009 period. In a Buenos Aires City hospital, 582 HIV negative TB patients received rifampin, isoniazid, pyrazinamide and ethambutol or streptomycin in the initial stage, followed by a second stage where patients were included in two groups: G1 composed by 424 patients (period 1/1/1979-12/31/1999) who received either rifampin and isoniazid or rifampin and streptomicin twice a week, and G2, with 158 patients (period 1/1/2000-12/31/2009) who received either rifampin and isoniazid twice or three times a week. National and Buenos Aires City TB Control Programs recommendations were followed. Patients who underwent DOT had higher completeness rates than those included in self-administered therapy (82.8% vs. 48.7%), (p <0.0001). Mean age: 36.3 ± 15.3 years, males: 63.1% and 69.4% were Argentine citizens. A 8.9% had been previously treated, 6.1% had co-morbidities. A 70.6% of pulmonary cases was bacteriologically confirmed, 82.8% of them completed the treatment, while 11.5% defaulted. Adverse effects to antituberculosis drugs were observed in 9.5% of cases; male patients showed higher rates of non adherence. G2 had a lower proportion of native people (48.7% vs. 77.1%), (p = 0.0001), higher frequency of co-morbidities (10.7% vs. 4.4%), (p = 0.005), of bacteriologically confirmed pulmonary cases (95% vs. 87%), (p = 0.02) and more adverse effects than G1 (17% vs. 6.6%), (p = 0.0001). In coincidence with other experiences, this work shows high treatment success rates in patients treated under DOT strategy.

Abstract
A case of isoniazid induced gynecomastia is being reported in an 18-year old male, who received a re-treatment regimen for the relapse of pulmonary tuberculosis (TB). At the end of two months of the treatment, the patient developed a painless unilateral gynecomastia, which completely disappeared after a month of the cessation of isoniazid. A review of literature on isoniazid induced gynecomastia is discussed.

Abstract
Six-month regimen consisting of two-month initial intensive phase of isoniazid (INH), rifampicin (RFP), pyrazinamide (PZA) and ethambutol, (or streptomycin) and four-month maintenance phase of INH and RFP has been established as the global standard. Alternatively, 9-month regimen without PZA is acceptable for patients like elderly persons. Standard regimen is well tolerated in most patients. However some patients have adverse reactions. The frequent and serious reaction is hepatic toxicity caused by INH and PZA. Close monitoring of serum aminotransferase at every two weeks of initial treatment phase is recommended. Hypersensitivity to INH and RFP is common reaction seen in 4-5 percent of the general population. About 60-80% patients who had hypersensitivity can continue the standard regimen by desensitization therapy.

Abstract
We report a skin Mycobacterium marinum infection presenting as wide ulcerative lesions of the arm (4 cm for the widest) in a hypoxic COPD patient who takes 4 mg methylprednisolone daily and higher doses during exacerbations. Diagnostic delay as well as glucocorticoid use could be responsible for the extension of the lesions. Clinical resolution occurred after three months of antibiotic therapy. Extensive ulcerative lesions are uncommon in Mycobacterium marinum infection in an immunocompetent host. This case emphasizes the potential and unusual harmful effect of long-term glucocorticoid therapy used in obstructive lung disease on the spread of Mycobacterium marinum infection.

Abstract
CONTEXT Fixed-dose combinations (FDCs) of drugs for treatment of tuberculosis have been advocated to prevent the emergence of drug resistance. OBJECTIVE To assess the efficacy and safety of a 4-drug FDC for the treatment of tuberculosis. DESIGN, SETTING, AND PATIENTS The Study C trial, a parallel-group, open-label, noninferiority, randomized controlled trial conducted in 11 sites in Africa, Asia, and Latin America between 2003 and 2008. Patients were 1585 adults with newly diagnosed smear-positive pulmonary tuberculosis. INTERVENTIONS Patients were randomized to receive daily treatment with 4 drugs (rifampicin, isoniazid, pyrazinamide, ethambutol) given as an FDC (n = 798 patients) or separately (n = 787) in the 8-week intensive phase of treatment. MAIN OUTCOME MEASURE Favorable treatment outcome, defined as negative culture result at 18 months post randomization and not having already been classified as unfavorable. Noninferiority was dependent on consistent results from a per-protocol and modified intention-to-treat analysis, using 2 different models for the latter, classifying all changes of treatment or refusal to continue treatment (eg, bacteriological failure/relapse, adverse event, default, drug resistance) as unfavorable (model 1) and classifying changes of treatment for reasons other than therapeutic outcomes according to their 18-month bacteriological outcome if available (post hoc model 2). The prespecified noninferiority margin was 4%. RESULTS In the per-protocol analysis, 555 of 591 patients (93.9%) had a favorable outcome in the FDC group vs 548 of 579 (94.6%) in the separate-drugs group (risk difference, -0.7% [90% confidence interval {CI}, -3.0% to 1.5%]). In the model 1 analysis, 570 of 684 patients (83.3%) had a favorable outcome in the FDC group vs 563 of 664 (84.8%) in the separate-drugs group (risk difference, -1.5% [90% CI, -4.7% to 1.8%]). In the post hoc model 2 analysis, 591 of 658 patients (89.8%) in the FDC group and 589 of 647 (91.0%) in the separate-drugs group had a favorable outcome (risk difference, -1.2% [90% CI, -3.9% to 1.5%]). Adverse events related to trial drugs were similarly distributed among treatment groups. CONCLUSIONS Compared with a regimen of separately administered drugs, a 4-drug FDC regimen for treatment of tuberculosis satisfied prespecified noninferiority criteria in 2 of 3 analyses. Although the results do not demonstrate full noninferiority of the FDCs compared with single drugs given separately using the strict definition applied in this trial, use of FDCs is preferred because of potential advantages associated with the administration of FDCs compared with separate-drug formulations.
