BACKGROUND Rifampin is used as adjunctive therapy for Clostridium difficile-associated disease, and the drug's derivative, rifaximin, has emerged as an attractive antimicrobial for treatment of C. difficile-associated disease. Rifampin resistance in C. difficile strains has been reported to be uncommon. METHODS We examined the prevalence of rifampin resistance among 470 C. difficile isolates ...
background:chronic synovitis is one of the most important complications in haemophilic patients. rifampin is anantibiotic which its intra-articular injecion leads to destruction of the synovial membrane of haemophilic patientsmedically.materials and methods: between september 2003 and november 2005, we administered intra-articular rifampinin ١۶ haemophilic joints of ٨ haemophilic patients.resul...
Identification of Mycobacterium tuberculosis and Rifampin Resistance in Pulmonary Extra-pulmonary Clinical Specimens Using the Gene Xpert MTB/RIF Assay
A rifampin-susceptible strain (VSV Rif+) was selected from the wild vesicular stomatitis virus (VSV) population unsusceptible to rifampin. The VSV Rif+ was blocked in its intracellular replication in the presence of rifampin. In cells, rifampin affected primarily VSV Rif+ transcription, but to a different extent than in a cell-free system. In addition, a decrease in the amount of VSV Rif+ prote...
Purpose: To establish the method for the analysis of rifampin quinone and hydrazone in fixeddose combination tablets (FDC) containing rifampicin with or without sodium ascorbate as an additive. Methods: The International Pharmacopoeial (IP) method for the estimation of rifampin quinone in FDC was modified. The extraction solvent (methanol/buffer mixture) of the IP method was replaced with ethyl...
Rifampin, an antibiotic widely used for the treatment of mycobacterial infections, produces hepatic, renal and bone marrow toxicity in human and animals. In this study, the protective effects of vitamin C and n-acetylcysteine (NAC) on the toxicity of rifampin on HepG2 cells were investigated. Human hepatoma cells (HepG2) were cultured in 96-well M of rifampin in the presence of microplate and e...
Antimicrobial therapy for brain infections is notoriously difficult because of the limited extent of knowledge about drug penetration into the brain. Therefore, we determined the penetration of rifampin into various compartments of the human brain, including the cerebral extracellular space (CES). Patients undergoing craniotomy for resection of primary brain tumors were given a standard dose of...
Cultured human hepatocytes are a valuable in vitro system for evaluating new molecular entities as inducers of cytochrome P450 (P450) enzymes. The present study summarizes data obtained from 62 preparations of cultured human hepatocytes that were treated with vehicles (saline or dimethylsulfoxide, 0.1%), beta-naphthoflavone (33 microM), phenobarbital (100 or 250 microM), isoniazid (100 microM) ...
BACKGROUND Guidelines for latent tuberculosis infection do not consider drug-resistance patterns when recommending treatment for immigrant children. OBJECTIVES The purpose of this research was to decide at what rate of isoniazid resistance a different regimen other than isoniazid for 9 months should be considered. METHODS We constructed a decision tree by using published data. We studied 3 ...
