70 patients with pulmonary tuberculosis, experiencing side-effects associated with antibacterial preparations were examined as were 30 patients receiving similar therapy with no complications being developed, and 20 apparently healthy subjects. It was established that the level of antigen-binding lymphocytes depends on the extent of sensitization to the allergen in question and reaches the highest values in patients presenting with adverse reactions. Preliminary treatment of lymphocytes with a medicamentous preparation results in some reduction of the number of antigen-binding lymphocytes. Values for the index of restoration of stimulated expression of the receptors to the medicinal preparations by trypsinized lymphocytes are higher in patients experiencing adverse reactions than they are in patients with pulmonary tuberculosis, presenting with no ill-effects, and in donors.

High risk of drug-resistant tuberculosis in IGRA-negative contacts: should preventive treatment be considered?

Purpose: Deciding whether to provide preventive treatment to contacts of individuals with multidrug-resistant (MDR) tuberculosis is complex.
Methods: We present the diagnostic pathways, clinical course and outcome of tuberculosis treatment in eight siblings from a single family. Tuberculosis disease was diagnosed by Mycobacterium tuberculosis culture and molecular detection of M.

Objective: In clinical practice, an accurate and efficient detection approach for pulmonary tuberculosis (PTB) is highly needed. The fluorescence hybridization (FISH) assay for PTB might be a suitable alternative to current tests. However, a systematic assessment of the diagnostic performance of this new approach is not available.

Early and accurate diagnosis of pulmonary tuberculosis (TB) is key to effective outbreak management, and in humans thoracic radiography is used extensively for screening purposes. In wildlife TB radiography is a relatively accessible diagnostic tool, particularly in under-resourced settings, however its use is limited by body size. Sun bears are susceptible to human-associated TB, and their small body size makes thoracic radiography feasible.

Tuberculosis (TB) significantly increases the risk of developing chronic obstructive pulmonary disease (COPD), positioning TB-associated COPD (TB-COPD) as a distinct category within the spectrum of respiratory diseases prevalent, especially in low- and middle-income countries. This condition results from the body's immune response to TB, leading to prolonged inflammation and consequent persistent lung damage. Diagnostic approaches, particularly post-bronchodilator spirometry, are vital for identifying airflow obstruction and confirming TB-COPD.

BMJ Open Respir Res

Department of Respiratory Sciences, University of Leicester, Leicester, UK.
Background: Tuberculosis (TB) diagnosis in the UK is impacted by delay and suboptimal culture-based microbiological confirmation rates due to the high prevalence of paucibacillary disease. We examine the real-world clinical utility of Xpert MTB/RIF Ultra (Xpert-Ultra) as a diagnostic test and biomarker of transmissible infection in a UK TB service.
Methods: Clinical specimens from suspected TB cases triple tested (smear microscopy, mycobacterial culture and Xpert-Ultra) at University Hospitals of Leicester NHS Trust (1 March 2018-28 February 2019) were retrospectively analysed.
