Tubercular infection of hydatid cyst of the chest wall in an immunocompetent individual is rare. Immune modulation for symbiosis between host cells and the parasite - Echinococcus granulosus favors tubercular infection. In this case report, we describe a case of both these chronic diseases coexisting together, to present as chest wall mass.

Disseminated Mycobacterium avium complex (DMAC) has historically been described in the immunocompromised. The current epidemiologic research suggests that the incidence of nontuberculous mycobacterial infections is increasing. We present a case of DMAC infection manifesting as hepatic granulomas in a 35-year-old immunocompetent female. This case suggests DMAC infection in a patient without traditional epidemiological risk factors.

Here, we present possible death caused by Mycobacterium gordonae infection in a patient with angioimmunoblastic T-cell lymphoma. Our patient was severely immunocompromised in whom we suspect to an infection, but we did not have isolates until she died. After she died, we received a positive sputum culture of M. gordonae. We conclude that when having severely immunocompromised patients with suspicion of infection but without isolates we should always consider the saprophytic mycobacteria. These mycobacteria require a long period of isolation, but patients with these mycobacteria are potentially curable if appropriate treatment is applied for a sufficiently long period...

We report two cases of patients with biopsy-proven idiopathic pulmonary fibrosis (IPF) who were treated with new antifibrotic agent for pirfenidone for more than 12 months. Both cases developed cavitary pulmonary tuberculosis (TB) proven by positive sputum TB culture. Both cases were treated with standard anti-TB drugs for 9 months and had complete clinical and radiological resolution. To our knowledge, these are the first reported human cases of patients with IPF who have been on pirfenidone and developed cavitary pulmonary TB...

Causes of lytic bone lesions include benign, malignant, and infectious processes. Lytic lesions due to tuberculosis (TB) may closely mimic those due to tumors such as bone cyst, osteoblastoma, osteosarcoma, and metastatic bone disease radiologically. Histopathology and culture help in definitive diagnosis and prompt management. We describe an immunocompetent patient with isolated lytic bone lesion in the distal part of ulna due to TB to make the readers aware of such unusual presentations of TB.

Tuberculosis (TB) is a major global health problem. Awareness of liver injury due to anti-TB therapy is vital because fulminant hepatic failure is a devastating and often fatal condition without liver transplantation. Here, we report for the first time, two patients of fatal liver injury due to anti-TB drugs in the presence of alpha-1 antitrypsin deficiency. Based on the triad of rapid loss in hepatocyte function, the onset of hepatic encephalopathy, and absence of a prior history of liver disease, the diagnosis of acute liver failure was established...

BACKGROUND: Isoniazid (INH) resistance in Mycobacterium tuberculosis has been mainly attributed to mutations in katG (64%) and inhA (19%). However, 20%-30% resistance to INH cannot be explained by mutations alone. Hence, other mechanisms besides mutations may play a significant role in providing drug resistance. Here, we explored the role of 24 putative efflux pump genes conferring INH-resistance in M. tuberculosis. MATERIALS AND METHODS: Real-time expression profiling of the efflux pump genes was performed in five INH-susceptible and six high-level INH-resistant clinical isolates of M...

BACKGROUND: Tuberculosis is one of the most prevalent diseases in Pakistan. Pakistan has the highest burden of MDR-TB in the Eastern Mediterranean region. Ethionamide is an anti-tuberculous drug frequently used to treat MDR-TB. Its drug susceptibility testing is not easily available in resource limited settings. Since it acts on the same target protein as isoniazid (inhA protein encoded by inhA gene), we sought to find out if phenotypic isoniazid resistance can be a marker of ethionamide resistance...

BACKGROUND: The incidence of extrapulmonary and disseminated tuberculosis (TB) cases is increasing worldwide, and this growth significantly impacts TB-related morbidity and mortality. Little is known about the host risk factors for extrapulmonary and disseminated TB. In this study, we examined those risk factors. MATERIALS AND METHODS: We conducted a retrospective review of all TB cases admitted to Sultan Qaboos University Hospital from 2006 to 2015. We compared extrapulmonary TB (EPTB) cases with pulmonary and disseminated TB cases...

BACKGROUND: The first line anti-tuberculosis drug pyrazinamide (PZA) is important when treating PZA susceptible multidrug-resistant tuberculosis (MDR-TB). Several drug resistance surveys have however reported PZA resistance among a significant proportion of multidrug-resistant (MDR) cases and this undoubtedly highlights the need for accurate and reliable detection of PZA resistance. Unfortunately, the testing of PZA susceptibility is associated with technical difficulties and even though the introduction of pncA sequencing has helped to address this issue, misclassification may still occur...

BACKGROUND: Patients in countries endemic for chronic viral hepatitis are more vulnerable to antituberculosis therapy-induced liver disorders (ATT-LDs). The aim of this study was to explore the role of cholecalciferol in prophylaxis against ATT-LD among patients with pulmonary tuberculosis (TB) receiving ATT. MATERIAL AND METHODS: We conducted a hospital-based, prospective, randomized, comparative study which included 300 consecutive, naïve patients with pulmonary TB eligible for ATT...

BACKGROUND: Enzymes responsible for cell wall development in Mycobacterium tuberculosis are considered as potential targets of anti-tuberculosis (TB) agents. Mycobacterial cyclopropane mycolic acid synthase 1 (CmaA1) is essential for mycobacterial survival because of its critical role in synthesizing mycolic acids. MATERIALS AND METHODS: We screened compounds that were capable of interacting with the mycobacterial CmaA1 active site using a virtual compound library with an in silico structure-based drug screening (SBDS)...
