Rates and risk factors for acquired drug resistance and association with outcomes among patients with multidrug-resistant tuberculosis (MDR TB) are not well defined. In an MDR TB cohort from the country of Georgia, drug susceptibility testing for second-line drugs (SLDs) was performed at baseline and every third month. Acquired resistance was defined as any SLD whose status changed from suscept...

A definitive marker determining the bacillary load of Mycobacterium tuberculosis (MTB), the causative agent of tuberculosis (TB), and hence disease severity, is required for patient monitoring and management. In this study, the association among T-cell responses based on the interferon-gamma release assay (IGRA) and the tuberculin skin test (TST), the sputum acid-fast bacilli (AFB) grade and ty...

The real time PCR Xpert ® MTB/RIF is fundamental for rapid diagnosis in paucibacillary respiratory samples and for the detection of multidrug-resistant TB cases. This paper aimed to determine its performance on different extrapulmonary samples. We determined sensitivity, specificity, positive and negative predictive value on respiratory and non-respiratory samples collected from January 2010 to...

The treatment of multidrug-resistant tuberculosis (TB) requires the use, for long periods, of drugs liable to cause significant side effects. In the case of misdiagnosis of multidrug-resistant TB, the patient is exposed to toxic substances without any benefit. In low-income countries, where the microbiological diagnosis of TB relies on microscopy only, the misdiagnosis of multidrug-resistant TB...

The iso-nicotinic acid hydrazides are valuable agents against tuberculosis exerting a powerful bacteriostatic action on the tubercle bacillus,’ diffusing readily into the cerebro spinal fluid,2 concentrating (as demonstrated by tissue cultures) effectively within macrophages3 and absorbed after oral administration without gastro-intestinal irritation. Such a combination of desirable attributes ...

INTRODUCTION Pulmonary pneumatoceles are thin-walled, air-filled cysts that develop within the lung. Most often, they occur as a sequela to acute pneumonia, commonly caused by Staphylococcus aureus, and are found more frequently in infants and young children. Adult tuberculous pulmonary pneumatoceles are seldom reported. CASE PRESENTATION We reported a case of pulmonary tuberculosis with pneu...

BACKGROUND Multidrug-resistant tuberculosis has emerged as a global threat. The aim of this work was to compare the CT findings of primary multidrug-resistant tuberculosis and drug-sensitive tuberculosis in non-AIDS adults. MATERIAL AND METHODS From January 2012 to February 2016, 89 patients with primary multidrug-resistant tuberculosis were retrospectively reviewed, and 89 consecutive drug s...

n Society http cense. Abstract Background: Pulmonary tuberculosis (TB) is a widely spread disease, usually treated by multidrug therapy, nevertheless there are increasing number of cases in which medical treatment fails and requires surgical intervention specially those with large cavitary lesions or persistent sputum positive for Ziehl Neelsen (ZN) stain. Our objective was to assess the role o...

A prospective study was conducted on 75 consecutive cases of primary cavitary pulmonary tuberculosis in hospitalized children below 2 years to determine the spectrum of the disease. Diagnosis was based on clinical, radiological, tuberculin test and histopathological findings and not on isolation of tubercle bacilli. Peak age was 7-12 months. Ten mothers suffered from pulmonary fibrocavitary dis...
