background and aims: a selective and sensitive high performance liquid chromatography-electrospray ionization mass spectrometry method has been established for determination of methotrexate in human plasma. methods: methotrexate was extracted from plasma with acetonitrile. the mobile phase consisted of acetonitrile-water-formic acid 74: 25: 1(v/v). twenty µl of sample was chromatographically an...

background: nowadays, the first step in treatment of ectopic pregnancy (ep) is medical treatment. medical treatment with methotrexate (mtx) for ep is safe and effective method without the risks associated with the surgical procedure. but there are controversies between studies for which patients will respond better to medical treatment. objective: the aim of the present study was to investigate...

Methotrexate is an anti-rheumatic agent used as a first-line tretment for rheumatoid arthritis. Hematological malignancies like lymphoma or acute myeloid leukemia have been reported to be secondary to treatment with Methotrexate, but are very uncommon. We report here the first Moroccan case of RA patient on low dose MTX, who developed AML. We also reviewed all similar cases.

OBJECTIVES The mechanism of action of methotrexate in rheumatoid arthritis (RA) is complex. It may increase adenosine levels by blocking its conversion to uric acid (UA). This study was done to determine if methotrexate lowers UA in early RA (ERA). METHODS Data were obtained from Canadian Early Arthritis Cohort, an incident ERA cohort. All ERA patients with serial UA measurements were include...

This article describes a simple and fast high-performance liquid chromatography method for the determination of methotrexate (MTX) in plasma. Samples were collocted from children receiving high-dose MTX at shafa Hospital (Ahvaz University of Medical sciences, Ahvaz, iran) at various times after the end of eachinfusion. Plasma was deproteinized with trichloroacetic acid and the supernatant was i...

Myelosuppression is the life-threatening adverse effect of methotrexate. Impaired kidney function is a major aggravating factor of methotrexate-induced myelosuppression. In end-stage renal disease patients, methotrexate therapy must be with cautious because the efficacy of removal of methotrexate by means of dialysis is in doubt. In clinical practice, low-dose methotrexate is still used by clin...

Apremilast is a novel agent for the treatment of inflammatory based autoimmune disorders. The objective of this study was to assess the pharmacokinetic effects of co administration of apremilast and methotrexate on both agents. This was an open-label, multi-center, 3-treatment period, sequential study conducted in otherwise healthy subjects with psoriatic arthritis or rheumatoid arthritis who w...

Background. One of the treatment modalities for ectopic pregnancy is methotrexate. The purpose of this study is to identify the failure rate of methotrexate in treating patients with ectopic pregnancy as well as the risk factors leading to treatment failure. Methods. A retrospective chart review of 225 patients who received methotrexate as a primary management option for ectopic pregnancy. Fail...
