The objective of this report was to study the pharmacokinetics of rifampin (RMP), isoniazid (INH), and pyrazinamide (PZA) in HIV-infected children with tuberculosis (TB) treated with a thrice-weekly anti-TB regimen in the government program in India. Seventy-seven HIV-infected children with TB aged 1 to 15 years from six hospitals in India were recruited. During the intensive phase of TB treatm...

From 1986-1989, sixteen patients suffering from TB meningitis aged 12-58, with CSF smear or culture positive for Mycobacterium tuberculosis were hospitalized and treated with rifampin (RIF) , isoniazid (INH) , pyrazinamide (PZA) and ethambutol (ETB) for nine months. In all patients, ETB and PZA were withdrawn after three months and INH and RIF were continued for the next six months. 81.2 p...

Treatment of tuberculosis with main anti-tuberculosis drugs (OAT) includes isoniazid (INH), rifampin (RIF), ethambutanol (EMB), streptomycin (SM), and pyrazinamide (PZA). Although most Anti-Tuberculosis Drugs are acceptable in therapy, they have potential side effects, including the effects hematological reactions such as anemia. This study's purpose was to compare HB levels before after intens...

The pyrazinamidase from Mycobacterium smegmatis was purified to homogeneity to yield a product of approximately 50 kDa. The deduced amino-terminal amino acid sequence of this polypeptide was used to design an oligonucleotide probe for screening a DNA library of M. smegmatis. An open reading frame, designated pzaA, which encodes a polypeptide of 49.3 kDa containing motifs conserved in several am...

BACKGROUND Although resistance to isoniazid (INH) is the most common form of drug resistance seen among Mycobacterium tuberculosis isolates, there have been few studies on the efficacy and optimal duration of treatment for patients with INH-resistant tuberculosis (TB). METHODS We evaluated retrospectively the treatment outcomes of 39 patients who were treated for INH-resistant pulmonary TB. T...

In order to evaluate the Organon Teknika MB/BacT system used for testing indirect susceptibility to the alternative drugs ofloxacin (OFLO), amikacin (AMI), and rifabutin (RIF), and to the usual drugs of standard treatment regimes such as rifampin (RMP), isoniazid (INH), pyrazinamide (PZA), streptomycin (SM), ethambutol (EMB), and ethionamide (ETH), cultures of clinical specimens from 117 patien...

Pyrazinamide (PZA) is a first-line antituberculosis (anti-TB) drug capable of killing nonreplicating, persistent Mycobacterium tuberculosis. However, reliable testing of the susceptibility of M. tuberculosis to PZA is challenging. Using 432 clinical M. tuberculosis isolates, we compared the performances of five methods for the determination of M. tuberculosis susceptibility to PZA: the MGIT 960...

In a study of 302 Mycobacterium tuberculosis clinical isolates from the low-incidence Canadian-born population of Quebec, we characterized a large endemic strain family by using genomic deletions. The DS6(Quebec) deleted region (11.4 kb) defined a strain family of 143 isolates encompassing two subgroups: one characterized by pyrazinamide (PZA) susceptibility and the other marked by a PZA-monore...

OBJECTIVES To compare the efficacy and safety of febuxostat and allopurinol in pyrazinamide (PZA)-induced hyperuricemia in patients taking antitubercular therapy (ATT). METHODS This randomized controlled study was conducted at a tertiary care teaching institute of Rajasthan in all the sputum-positive tubercular patients aged between 18 and 65 years of either sex. Serum uric acid level was mon...
