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...

Background: Methotrexate has an important role in treatment of acute leukemia. We measured methotrexate level in CSF and blood of children with acute lymphoblastic leukemia to determine complications and outcomes. Materials and Methods: One hundred and twenty patients (73 male, 47 female), with mean age at diagnosis of 6.1 years (11mo_15years) entered the study. Patients were divided into two...

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...

Rheumatoid arthritis (RA) is a chronic disease characterized by the painful joints, inflammation, uncontrolled proliferation of synovial tissue and multisystem comorbidities. Weekly low-dose methotrexate (MTX) has been established as effective treatment in RA patients. MTX is converted to gamma-glutamyl polyglutamates, an active form of MTX, through the action of folylpolyglutamate synthetase i...

We previously developed a new formulation of methotrexate (MTX) that is adsorbed onto a suspension of activated carbon particles (MTX-CH) and reported the usefulness of local administration in murine tumors. The present study examines the effects of human colon carcinoma (LoVo) xenografts and the acute toxicity of MTX-CH compared with MTX aqueous solution (MTX-AQ) in mice. In therapeutic experi...

Background Former findings suggested that MTX-based combination therapies show improved efficacy and safety compared to monotherapy [1] . Several studies [2] have been conducted analysis on therapies, but there is a lack of systematic involving MTX+TCM (Traditional Chinese medicine) therapies. Objectives To assess the effectiveness adverse events Methotrexate-based (MTX-based) therapies(especia...

A new sensitive, simple and rapid method for determination of methotrexate (MTX) was developed based on quenching effects of MTX on the fluorescence intensity of Tb3+-1,10-phenanthroline complex. The fluorescence intensity was measured with excitation wavelength of 300 nm and emission wavelength of 545 nm and the quenched fluorescence intensity is proportional to the concentration of MTX in Tris...

OBJECTIVE To investigate the effect of methotrexate (MTX) and albumin coupled with methotrexate (MTX-HSA) on cartilage invasion and induction of perichondrocytic degradation by rheumatoid arthritis synovial fibroblasts (RA SF) in vivo. METHODS Human cartilage and RA SF were co-transplanted in three groups of severe combined immunodeficient mice (SCID), which received 1 mg/kg free MTX (n = 9),...

Abstact：objective To investigate acute kidney injury (AKI) in children with acute lymphoblastic leukemia (ALL) who received high dose methotrexate (MTX) chemotherapy and explore the corresponding treatment. Methods 180 children who received high dose MTX chemotherapy were observed with serum MTX concentration and serum creatinine. Patients with AKI of stage 3 or poor response to conventional tr...
