TB PRACTECAL is a multi-centre, open label, multi-arm, randomised, controlled, phase II-III trial; evaluating short treatment regimens containing bedaquiline and pretomanid in combination with existing and re-purposed anti-TB drugs for the treatment of biologically confirmed pulmonary multi drug-resistant TB (MDR-TB).

Pulmonary Tuberculosis and Vitamin D

Tuberculosis

Tuberculosis and vitamin D deficiency are important public health problems in India. Before the advent of effective antitubercular therapy, patients with tuberculosis were advised treatment and rest at sanatorium where sunshine was available in plenty. There have been reports associating vitamin D deficiency with tuberculosis in terms of incidence and beneficial response following addition of vitamin D to antitubercular therapy. Sputum AFB conversion rate is higher in patients with tuberculosis supplemented with vitamin D. The present study would systematically assess role of adjunct vitamin D therapy (cholecalciferol) in patients with pulmonary tuberculosis.

POC Strategies to Improve TB Care in Advanced HIV Disease

Extrapulmonary TuberculosisTuberculosis3 more

Tuberculosis (TB) remains the major cause of morbidity and mortality among patients with HIV. Sub-optimal diagnostics contributes towards poor patient outcome and there is an urgent need to identify non-sputum-based point-of-care diagnostic tests. The urine based lateral flow lipoarabinomannan TB diagnostic test (LF-LAM) is a simple, inexpensive point-of-care test. In 2015, the World Health Organization endorsed LF-LAM for conditional use among patients with advanced HIV, but uptake of the test in clinical practices has been poor. The investigators aim to identify point-of-care (POC) strategies that can improve TB case detection and clinical outcomes among patients with advanced HIV. The project includes a main study and two sub-studies. The main study is a multicenter stepped wedge cluster-randomized controlled trial of LF-LAM implementation among patients with advanced HIV with 8-weeks follow-up. LF-LAM will be added to standard care and implemented stepwise at three hospitals in Ghana. Education in national TB treatment guidelines in collaboration with the Tuberculosis Control programme in Ghana, and Clinical audit of clinical staff with feedback, will be used to assess and strengthen LF-LAM implementation. The primary outcome time to TB treatment, for which a sample size of 690 participants will provide >90% power to detect a minimum of 7 days reduction. Secondary outcomes are: TB related morbidity, TB case detection, time to TB diagnosis and overall early mortality at 8 weeks. The HIV-associated TB epidemiology including genotypic analyses of M. tuberculosis isolates obtained through the main study will be described. In sub study A, focused ultrasound of lungs, heart and abdomen will be performed in a sub cohort of 100 participants. In sub study B, the investigators will establish a biobank and data warehouse for storage of blood, urine and sputum samples collected from participants that enter the study at Korle-Bu Teaching hospital. It is expected that LF-LAM will lead to earlier diagnosis and treatment of TB. Findings may further guide scaling-up of LF-LAM. The HIV-associated epidemic including genotypic properties and resistance properties which is important for improved management will be detailed. The investigators further expect to evaluate the potential of bedside ultrasound as a clinical tool in management of HIV/TB co-infected patients. The unique Ghanaian HIV-cohort and biobank may facilitate rapid evaluation of future prognostic biomarkers and new point-of-care TB diagnostic tests.

DIAGNOSIS of PULMONARY TUBERCULOSIS Through HUMAN BREATH (TBENOSE)

TuberculosisPulmonary1 more

Tuberculosis (TB) is one of the top 10 causes of death in the world. More than 95% of TB deaths are in middle- and middle-income countries. Low incomes and long-term diagnosis promote this persistence. In 2017, Cameroon was the 3rd in the top of 20 countries with the highest estimated numbers of incident TB cases among people living with HIV, based on the severity of their TB burden. World Health Organization (WHO) encourages the introduction of rapid, non-invasive and cheaper screening tests. In this scope, this study proposes the collection of exhaled breath samples and their analysis through the electronic nose made in Tor Vergata University (TV eNose) to diagnose TB and TB-HIV on their participants.

Integrating Electronic Patient Reported Biometric Measures (ePReBMs) From Wearable Devices in Respiratory...

Progressive Fibrosing Interstitial Lung DiseaseLung Transplant3 more

Lung diseases are one of the most common causes of emergency room visits. There are very few tools that are able to predict which patients will have a worsening or increasing severity of their condition. There are also limited ways to check the health of patients with respiratory conditions at home and during the time between medical appointments. The ADAMM-RSMTM device records heart rate, breathing rate, temperature, cough and activity while wearing it. This study will test participants willingness to wear the device and perform ongoing monitoring to assess the possibility to predict the onset and increases in severity of their lung conditions.

ENOSE in Pulmonary Tuberculosis in Yogyakarta

Pulmonary Tuberculosis SuspectedOther Specified Chronic Obstructive Pulmonary Disease2 more

Electronic noses detecting patterns of volatile molecules have recently been introduced for different diagnostic purposes. The diagnostic accuracy of a prototype e-nose device (Bruins et al (2013) in Bangladesh showed sensitivity of 76.5-95.9% and specificity of 85.3-98.5%. Here the investigators test a production type point-of-care hand-held device with less detectors. The investigators explore factors such as food intake, smoking, and co-morbidity, as well as the impact of TB treatment, and address the question whether the device could help monitor disease and response to treatment.

Induced Sputum Versus Bronchoscopy in Smear Negative Pulmonary Tuberculosis

Pulmonary Tuberculosis

This is a randomised study that compares different diagnostic approaches for diagnosing pulmonary tuberculosis in patients suspected of pulmonary tuberculosis in whom the three classic (non-induced) sputum samples didn't show tuberculous bacillus on direct examination. The investigators compare the sensibility of induced sputum technique with an endoscopic approach (CT-scan followed by BAL and fluoroscopy-guided transbronchial biopsies and eventually sputum collection immediately after the bronchoscopy). People in high risk population for tuberculosis undergoing screening by chest X-ray or symptomatic patients will be admitted to the hospital if their chest X-ray shows a suspicion of active tuberculosis. According good clinical practice: (non-induced) sputum samples will be taken at admission and every following morning. If direct examination and PCR of the first three classic sputum samples are negative: patients will be randomised in two groups with a different diagnostic approach (induced sputum versus endoscopic approach) The aim of our study is to proof that a thoroughgoing endoscopic approach has a higher sensibility than an induced sputum in the diagnosis of pulmonary tuberculosis in patients with a high suspicion of active tuberculosis on the chest X-ray but with a negative direct examination and/or PCR on three consecutive normal sputum samples. The investigators will include 154 patients (based on a statistical analysis for a hypothesis that the endoscopic approach has a sensibility that's twice the sensibility of the induced sputum). first arm: 2 consecutive induced sputum using an ultrasonic nebulizer. second arm: CT thorax to evaluate the exact anatomic localisation of the disease followed by fluoroscopy-guided bronchoscopy for BAL (bronchoalveolar lavage) and transbronchial biopsies. A sputum sample immediately after the endoscopy will be collected if possible.

Comparison Between Two Strategies for the Diagnosis of TB

Pulmonary TB

Tuberculosis (TB) is a major cause of death among the "communicable" diseases in the world. Pulmonary TB, the main localization, leads to the dissemination of cases. An earlier diagnosis of contagious pulmonary TB is a cornerstone to stop the air transmission. The aim of the study will be to compare two strategies, in patients with a chest-X-ray in favour of contagious pulmonary TB: the classical strategy of sputa collection during three consecutive early mornings, versus the studied strategy of sputa collection at hour h, hour h+1, hour h+2 during the first early morning.
