A 41-year-old woman treated with isoniazid (INH) for latent tuberculosis infection and an oral corticosteroid for sarcoidosis developed severe anemia two months after initiating INH. A bone marrow examination showed erythroblastopenia, and a diagnosis of INH-induced pure red cell aplasia (PRCA) was made. Her reticulocyte count and hemoglobin levels improved two weeks after discontinuation of INH. A literature review of INH-induced PRCA shows that it occurs very rarely in the context of autoimmune disorders...

The place of prodrugs in the current antitubercular therapeutic arsenal is preponderant, since two of the four first-line antitubercular agents, isoniazid (INH) and pyrazinamide (PZA), need to be activated by Mycobacterium tuberculosis before exerting their activity. In addition, six other prodrugs can be found in the second- and third-line therapeutic regimens, namely ethionamide (ETH), prothionamide (PTH), p-aminosalicylic acid (PAS), thiacetazone (TAC), isoxyl (ISO) and the recently approved delamanid. The emergence of mycobacterial strains resistant to one or several antitubercular agents is one of the main issues of the antitubercular therapy...

BACKGROUND: Sub-Saharan Africa continues to document high pediatric tuberculosis (TB) burden, especially among the urban poor. One recommended preventive strategy involves tracking and isoniazid preventive therapy (IPT) for children under 5 years in close contact with infectious TB. However, sub-optimal effectiveness has been documented in diverse settings. We conducted a study to elucidate correlates to IPT strategy failure in children below 5 years in high burden settings. METHODS: A prospective longitudinal cohort study was done in informal settlings in Nairobi, where children under 5 years in household contact with recently diagnosed smear positive TB adults were enrolled...

Aim of the present study was to assess the hepatoprotective activity of goat milk on antitubercular drug-induced hepatotoxicity in rats. Hepatotoxicity was induced in rats using a combination of isoniazid, rifampicin, and pyrazinamide given orally as a suspension for 30 days. Treatment groups received goat milk along with antitubercular drugs. Liver damage was assessed using biochemical and histological parameters. Administration of goat milk (20 mL/kg) along with antitubercular drugs (Group III) reversed the levels of serum alanine aminotransferase (82 ± 25...

INTRODUCTION: Tuberculosis remains the leading causes of death worldwide with frequencies of mutations in rifampicin and isoniazid resistant Mycobacterium tuberculosis isolates varying according to geographical location. There is limited information in Zimbabwe on specific antibiotic resistance gene mutation patterns in MTB and hence, increased rate of discordant results and mortality due to inappropriate antibiotic prescriptions. The rpoB and katG genes molecular markers are used for detecting rifampicin and isoniazid resistance respectively...

BACKGROUND: Fluoroquinolones and second-line injectable drugs are the backbone of treatment regimens for multidrug-resistant tuberculosis, and resistance to these drugs defines extensively drug-resistant tuberculosis. We assessed the accuracy of an automated, cartridge-based molecular assay for the detection, directly from sputum specimens, of Mycobacterium tuberculosis with resistance to fluoroquinolones, aminoglycosides, and isoniazid. METHODS: We conducted a prospective diagnostic accuracy study to compare the investigational assay against phenotypic drug-susceptibility testing and DNA sequencing among adults in China and South Korea who had symptoms of tuberculosis...

Medical history A 77-year-old patient with transurethral resection of a bladder tumor was transferred due to persistent fever and progressive dyspnea despite antibiotic therapy for suspected urinary tract infection. Repeating the medical history revealed that a BCG immunotherapy of his non-muscle-invasive bladder carcinoma was performed the day before fever developed. Therefore, BCGitis was suspected. Examinations Laboratory parameters showed pancytopenia, elevated liver enzymes, eleveated C-reactive protein and hypoxemia...

To study the transmissibility of drug resistant mutant clones, M. tuberculosis samples were isolated from the patients of the clinical department and the polyclinic of the Central TB Research Institute (n = 1455) for 2011-2014. A number of clones were phenotypically resistant to rifampicin (n = 829), isoniazid (n = 968), and fluoroquinolones (n = 220). We have detected 21 resistance-associated variants in eight codons of rpoB, six variants in three codons of katG, three variants in two positions of inhA, four variants in four positions of ahpC, and nine variants in five codons of gyrA, which were represented in the analyzed samples with varied frequencies...

OBJECTIVES: In Morocco, tuberculosis (TB) is a major public health problem with high morbidity and mortality. The main problem faced by the National TB program is the high rate of drug resistant (DR), particularly multi-drug resistant (MDR) strains. Diagnosis of DR-TB is mainly performed by conventional techniques which are time consuming with limited efficacy. In 2014, GenoType(®) MTBDRplus assay was introduced in Morocco for drug resistance testing. In this regard, the present study was planned to assess the diagnostic accuracy of GenoType(®) MTBDRplus assay...

Chemotherapy for tuberculosis (TB) is lengthy and could benefit from synergistic adjuvant therapeutics that enhance current and novel drug regimens. To identify genetic determinants of intrinsic antibiotic susceptibility in Mycobacterium tuberculosis (Mtb) we applied a chemical genetic interaction (CGI) profiling approach. We screened a saturated transposon mutant library and identified mutants that exhibit altered fitness in the presence of partially-inhibitory concentrations of rifampicin, ethambutol, isoniazid, vancomycin and meropenem, antibiotics of diverse mechanisms-of-action...

Levofloxacin is a widely used fluoroquinolone, mainly as a respiratory antimicrobial agent. It is employed as a second line therapeutic modality in pulmonary tuberculosis as well. The drug has been in use for ages, and is known to be both efficacious and safe. However, it is not free of adverse effects. The most dangerous ones are those involving the Central Nervous System (CNS). Although rare, levofloxacin can cause involuntary movements like chorea and myoclonus. Here by, we present a case of an elderly male patient who developed reversible myoclonus/chorea after a course of levofloxacin (which was initiated as part of his anti-tubercular therapy) following the development of peripheral neuropathy secondary to isoniazid...

Reactive arthritis, formerly called Reiter's syndrome, is one of the rare complications following intravesical instillation of Bacillus Calmette Guerin (BCG). A 58-year-old man was admitted to our hospital because of fever, hyperemia of conjunctiva, and arthralgia following the second course of intravesical instillation of BCG in the treatment of pT1 and pTis bladder cancer. We diagnosed him with reactive arthritis due to the clinical course. Reactive arthritis is usually well controlled with the discontinuation of instillation and administration of nonsteroidal anti-inflammatory drugs (NSAIDs)...

Acetylation is the major metabolic pathway of isoniazid (INH) mediated by N-acetyltransferases (NATs). Previous reports suggest that slow acetylators have higher risks of INH hepatotoxicity than rapid acetylators, but the detailed mechanisms remain elusive. The current study used Nat1/2(-/-) mice to mimic NAT slow metabolizers and to investigate INH metabolism in the liver. We found that INH acetylation is abolished in the liver of Nat1/2(-/-) mice, suggesting that INH acetylation is fully dependent on NAT1/2...

BACKGROUND: There are 8.6 million cases of active tuberculosis (TB) worldwide, and an estimated one-third of the world population has latent tuberculosis infection (LTBI). In the United States, up to 80% of active cases may be caused by untreated reactivated latent infection. A case of TB can spread rapidly impacting the readiness of a unit. To prevent the development of TB, it is critical that active duty service members with LTBI complete treatment. The use of isoniazid (INH) and rifapentine (RPT) as a directly observed therapy (DOT) treatment option was recommended by the Centers for Disease Control and Prevention in late 2011...
