The global emergence and spread of multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis has led to the re-examination of surgery as a possible adjunctive treatment. We present the case of a 26-year-old HIV-seronegative patient with XDR pulmonary tuberculosis refractory to medical therapy. Surgical resection of the patient's solitary(More)
BACKGROUND The country of Georgia has a high prevalence of tuberculosis (TB) and hepatitis C virus (HCV) infection. PURPOSE To determine whether HCV co-infection increases the risk of incident drug-induced hepatitis among patients on first-line anti-TB drug therapy. METHODS Prospective cohort study; HCV serology was obtained on all study subjects at the(More)
The pathogenesis of increasing drug resistance among patients with multidrug-resistant or extensively drug-resistant tuberculosis undergoing treatment is poorly understood. Increasing drug resistance found among Mycobacterium tuberculosis recovered from cavitary isolates compared with paired sputum isolates suggests pulmonary cavities may play a role in the(More)
A better understanding of second-line drug (SLD) pharmacokinetics, including cavitary penetration, may help optimize SLD dosing. Patients with pulmonary multidrug-resistant tuberculosis (MDR-TB) undergoing adjunctive surgery were enrolled in Tbilisi, Georgia. Serum was obtained at 0, 1, 4, and 8 h and at the time of cavitary removal to measure levofloxacin(More)
BACKGROUND New approaches are needed in the treatment of multidrug-resistant and extensively drug-resistant pulmonary tuberculosis (M/XDR-PTB). We evaluated the role of adjunctive surgical therapy in the treatment of M/XDR-PTB in the setting of directly observed treatment strategy (DOTS)-Plus implementation. METHODS We conducted an observational cohort(More)
Nyaditum resae (NR) is a galenic preparation of heat-killed Mycobacterium manresensis (hkMn). This is a new species that belongs to the Mycobacterium fortuitum complex, and it is present in drinking water-thus, regulatorily speaking, it is considered a food supplement. Preclinical studies in the murine model of active tuberculosis (TB) in the C3HeB/FeJ(More)
Improved knowledge regarding the tissue penetration of antituberculosis drugs may help optimize drug management. Patients with drug-resistant pulmonary tuberculosis undergoing adjunctive surgery were enrolled. Serial serum samples were collected, and microdialysis was performed using ex vivo lung tissue to measure pyrazinamide concentrations. Among 10(More)
OBJECTIVES Our aim was to retrospectively compare clinical data and characteristics of removed lesions of the cohort of patients undergoing therapeutical surgery for their tuberculosis. DESIGN AND METHODS Demographic and epidemiological details, clinical data, data on the surgery performed, macroscopic characteristics of the TB lesions removed, and(More)
The TB Portals Program is an international consortium of physicians, radiologists, and microbiologists from countries with a heavy burden of drug-resistant tuberculosis working with data scientists and IT professionals. Together, we have built the TB Portals, a repository of socioeconomic/geographic, clinical, laboratory, radiological, and genomic data from(More)
With the help of radioimmunoassay method 59 patients, which were operated for the various pulmonary diseases, has been examined. The activity of plasma renin, the level of angiotensin II, aldosterone were determined. Polycardiography with phasic analysis of myocardium contractility of the heart right ventricle, differential rheopulmonography, the zone(More)
