BACKGROUND Methotrexate (MTX) is an effective and safe drug in the treatment of juvenile idiopathic arthritis (JIA). Despite its safety, MTX-related gastrointestinal adverse effects before and after MTX administration, termed MTX intolerance, occur frequently, leading to non-compliance and potentially premature MTX termination. The aim of this study was to construct a risk model to predict MTX ...

introduction: this study was performed to analyze chromosomal aletrations in g1 and g2 immortalizedmolt-4 cell line following treatment with methotrexate (mtx) and cytarabine (ara-c) alone or incombination. material and methods: molt-4 cells were cultured and manitained in rpmi-1640 supplementedwith fetal calf serum, antibiotics and l-gluthamine. cells were treated with ara-c and mtx with aconc...

Background: Methotrexate (MTX), as antimetabolite and antifolate compound, is used to treat the certain types of tissue over activity and cancers. The MTX interferes with cell division through inhibiting the purine and pyrimidine synthesis. Moreover, the toxic impact of the MTX on gonadal tissues has been reported. Therefore, current study was designed to evaluate the protective effects of corn...

Patients with autoimmune conditions develop lymphoproliferative disorders (LPDs) at a higher frequency than normal both in association with and independent of Methotrexate (MTX). We describe a case of MTX-associated lymphoma in a patient with psoriasis on long-standing MTX. The case is notable for the initial tumor burden, the dramatic disappearance of the PET-CT findings on discontinuation of ...

BACKGROUND Methotrexate (MTX) eradicates leukemic cells by disrupting de novo nucleotide biosynthesis and DNA replication, resulting in cell death. Since its introduction in 1947, MTX-containing chemotherapeutic regimens have proven instrumental in achieving curative effects in acute lymphoblastic leukemia (ALL). However, drug resistance phenomena pose major obstacles to efficacious ALL chemoth...

Nine out of 14 patients treated with intraventricular methotrexate (MTX) for meningeal carcinomatosis from breast carcinoma and surviving more than 4 months developed disseminated necrotising leukoencephalopathy (DNL). All four patients who had received both intraventricular MTX and whole brain radiotherapy developed DNL. Five of the six patients who experienced an acute febrile reaction with m...

BACKGROUND Methotrexate (MTX) is the most commonly prescribed disease-modifying antirheumatic drug (DMARD) in rheumatoid arthritis. ATP-binding cassette transporter-A1 (ABCA1) and 27-Hydroxylase (HY27) are known antiatherogenic proteins that promote cellular cholesterol efflux. In THP-1 macrophages, MTX can promote the reversal of cholesterol transport, limit foam cell formation and also revers...

Methotrexate (MTX) remains the cornerstone therapy for patients with rheumatoid arthritis (RA), with well-established safety and efficacy profiles and support in international guidelines. Clinical and radiologic results indicate benefits of MTX monotherapy and combination with other agents, yet patients may not receive optimal dosing, duration, or route of administration to maximize their respo...

Current study was aimed to evaluating protective effects of cornus mas fruit extract (CMFE) in mice treated with methotrexate (MTX). For this purpose, 48 young mature male mice were divided into 6 groups. Control group received only normal saline (0.1 mL per day, intraperitoneally), and the second group was administered MTX (20 mg kg(-1) per week, intraperitoneally). The third, fourth and fifth...
