Human immunodeficiency virus (HIV)-infected individuals successfully treated for tuberculosis (TB) remain at risk of recurrence of the disease, especially in high TB incidence settings. We performed a systematic review, investigating whether secondary preventive therapy (sPT) with anti-TB drugs (preventive therapy in former TB patients with treatment success) is an effective strategy to prevent recurrence of TB in this patient group. We searched the databases PubMed, Cochrane Library, EMBASE, Web of Science and Google Scholar using the keywords HIV-infections, HIV, human immunodeficiency virus, AIDS, isoniazid, isoniazid preventive therapy (IPT), tuberculosis, TB, recurrence and recurrent disease, resulting in 253 potential publications...

Tuberculosis (TB) has been the most common opportunistic infection and cause of mortality among HIV-infected patients, especially in resource-limited countries. Clinical manifestations of TB vary and depend on the degree of immunodeficiency. Sputum microscopy and culture with drug-susceptibility testing are recommended as a standard method for diagnosing active TB. TB-related mortality in HIV-infected patients is high especially during the first few months of treatment. Integrated therapy of both HIV and TB is feasible and efficient to control the diseases and yield better survival...

A series of 20 hispolons/dihydrohispolons were synthesized and characterized by spectral data. These compounds were subjected to in vitro antitubercular activity screening against Mycobacterium tuberculosis (H37Rv) strain. The synthesized compounds showed varied antitubercular activity ranging from 100 to 1.6μg/mL. Among the screened compounds, four compounds (H1, H2, H3 and H15) have shown moderate activity with MIC 25μg/mL. Potent activities were observed for the dihydrohispolon derivative H14 (MIC 1.6μg/mL) followed by H13 (6...

In the last decade, there were 10 million new tuberculosis cases per year globally. Around 9.5% of these cases were caused by isoniazid resistant (INHr) Mycobacterium tuberculosis (Mtb) strains. Although isoniazid resistance in Mtb is multigenic, mutations in the catalase-peroxidase (katG) gene predominate among the INHr strains. The effect of these drug-resistance-conferring mutations on Mtb fitness and virulence is variable. Here, we assessed differences in bacterial growth, immune response and pathology induced by Mtb strains harboring mutations at the N-terminus of the katG gene...

Drug Induced Lupus Erythematous (DILE) is a rare adverse reaction to a large variety of drugs including Isoniazid (INH), with features resembling idiopathic Systemic Lupus Erythematosus (SLE). Diagnosis require identification of a temporal relationship between drug administered and symptom. It is an idiosyncratic reaction, with no pre-existing lupus. Our case highlights a rare presentation of isoniazid induced lupus with profound pancytopenia and mucosal ulcers, thus posing a diagnostic challenge. The patient was on multidrug treatment for pulmonary and knee joint tuberculosis...

A rapid detection of resistance in Mycobacterium tuberculosis is crucial for management and control of tuberculosis. This study evaluated a more rapid and cost-effective drug susceptibility testing (DST) protocol using primary isolates of M. tuberculosis in mycobacteria growth indicator tube (MGIT). Ninety-four M. tuberculosis isolates in MGIT were subjected to DST by the manufacturer's method, i.e., primary isolates were subcultured and DST was performed from positive cultures for a maximum of 5days; and by our modified method, i...

Tuberculosis (TB) remains a leading cause of death from infectious disease worldwide with 80,000 pediatric deaths annually. Disease caused by Mycobacterium tuberculosis (Mtb) is usually asymptomatic in pediatric patients and resolves after completion of standard therapy with isoniazid (INH). Rare reports document children greater than 10 years of age in endemic regions developing adult type cavitary disease, an infectious pulmonary tuberculosis lesion. This is a notable case of post-infectious pulmonary TB disease with adult type cavitation in an immigrant adolescent, which developed even after completing standard therapy with INH...

The NADH:NAD(+) ratio is the primary indicator of the metabolic state of bacteria. NAD(H) homeostasis is critical for Mycobacterium tuberculosis (Mtb) survival and is thus considered an important drug target, but the spatio-temporal measurements of NAD(H) remain a challenge. Genetically encoded fluorescent biosensors of the NADH:NAD(+) ratios were recently described, paving the way for investigations of the metabolic state of pathogens during infection. Here we have adapted the genetically encoded biosensor Peredox for measurement of the metabolic state of Mtb in vitro and during infection of macrophage cells...

Many conventional drugs used today, including isoniazid, dapsone, and acetaminophen, are well recognized culprits of hepatotoxicity. With increasing use of complementary and alternative medical therapies, several herbal medicines, such as Ma-Huang, kava, and chaparral leaf, have been implicated as hepatotoxins. Hepatotoxicity may be the most frequent adverse reaction to these herbal remedies when taken in excessive quantities. A myriad of liver dysfunctions may occur including transient liver enzyme abnormalities due to acute and chronic hepatitis...

BACKGROUND: The results of some reports have suggested that treatment of isoniazid-resistant tuberculosis with the recommended regimens of first-line drugs might be suboptimal. We updated a previous systematic review of treatment outcomes associated with use of first-line drugs in patients with tuberculosis resistant to isoniazid but not rifampicin. METHODS: In this systematic review, we updated the results of a previous review to include randomised trials and cohort studies published in English, French, or Spanish to March 31, 2015, containing results of standardised treatment of patients with bacteriologically confirmed isoniazid-resistant tuberculosis (but not multidrug-resistant tuberculosis-ie, not resistant to rifampicin) in whom failure and relapse were bacteriologically confirmed...

Propidium monoazide (PMA) penetrates non-viable cells with compromised membranes. PMA has been proposed to improve the specificity of Xpert MTB/RIF (Xpert) for the detection of viable Mycobacterium tuberculosis. This study assessed the effect of PMA on Xpert cycle thresholds (CT) of M. tuberculosis made non-viable under antibiotic pressure. In vitro, we measured the difference between CT with and without PMA (ΔCT) in liquid cultures treated with one of six anti-tuberculosis drugs (isoniazid, rifampin, pyrazinamide, ethambutol, streptomycin, moxifloxacin) and found significant ΔCT only with isoniazid and ethambutol for pan-susceptible M...

Millions of individuals are infected with and die from tuberculosis (TB) each year, and multidrug-resistant (MDR) strains of TB are increasingly prevalent. As such, there is an urgent need to identify novel drugs to treat TB infections. Current frontline therapies include the drug isoniazid, which inhibits the essential NADH-dependent enoyl-acyl-carrier protein (ACP) reductase, InhA. To inhibit InhA, isoniazid must be activated by the catalase-peroxidase KatG. Isoniazid resistance is linked primarily to mutations in the katG gene...
