Liver Toxicity in Rheumatoid Arthritis Patients Treated With Methotrexate
Background:Methotrexate (MTX) is one of the most commonly used disease-modifying antirheumatic drugs in the treatment of rheumatoid arthritis (RA) which can be associated with toxic effects on different organs. This study was designed to investigate the hepatotoxic effects in RA patients treated with MTX. Methods: In this cross-sectional observational study, RA patients who received standard d...
متن کاملmethotrexate hepatotoxicity in patients with rheumatoid arthritis
background increases in aminotransferases (transaminitis) are potential major adverse reactions seen with long-term use of methotrexate (mtx). the aim of this study, therefore was to evaluate the incidence of mtx induced hepatotoxicity and its risk factors among rheumatoid arthritis (ra) patients. methods this retrospective study described 286 patients with ra who received ≤ 7.5 mg mtx weekly...
متن کاملCorrelation between methotrexate efficacy & toxicity with C677T polymorphism of the methylenetetrahydrofolate gene in rheumatoid arthritis patients on folate supplementation.
BACKGROUND & OBJECTIVES C677T polymorphism in the methylenetetrahydrofolate reductase (MTHFR) gene has been proposed as a pharmacogenomic marker for toxicity of methotrexate (MTX). We studied the relationship between the C677T gene polymorphism and toxicity and efficacy of MTX in patients with rheumatoid arthritis (RA) on folate supplementation. METHODS A total of 150 RA patients fulfilling A...
متن کاملInfluence of reduced folate carrier and dihydrofolate reductase genes on methotrexate-induced cytotoxicity.
PURPOSE The aim of this study is to investigate the effect of genetic variations and the expression of the reduced folate carrier (RFC) and dihydrofolate reductase (DHFR) on the drug sensitivity to methotrexate (MTX) in different cancer cell lines. MATERIALS AND METHODS We examined the six human cancer cell lines (MCF-7, AGS, A549, NCI-H23, HCT-116 and Saos-2). The cytotoxicity of MTX was mea...
متن کامل[Methylenetetrahydrofolate reductase polymorphisms in methotrexate treatment of rheumatoid arthritis patients. Review of the literature and personal experience].
Methotrexate is still a mainstay of rheumatoid arthritis treatment, but a significant variability in drug response is observed among patients. It has been proposed that C677T and A1298C polymorphisms of methylenetetrahydrofolate reductase (MTHFR), an enzyme involved in the folate pathway, could be related to its efficacy and toxicity. Many studies have investigated the predictive value of such ...
