OBJECTIVE To evaluate the efficacy of rituximab (R) when added to high-dose methotrexate (HD-MTX) in patients with newly diagnosed immunocompetent primary CNS lymphomas (PCNSLs). METHODS Immunocompetent adults with newly diagnosed PCNSL treated at The Johns Hopkins Hospital between 1995 and 2012 were investigated. From 1995 to 2008, patients received HD-MTX monotherapy (8 g/m2 initially every...

Continuous i.v. thymidine (TdR) was given to 12 patients with metastatic cancer in an attempt to prevent methotrexate (MTX) toxicity. MTX was infused in 27 courses with progressive dose increase from 80 mg/sq m for 24 hr to 6 g/sq m for 72 hr. TdR at 8 g/sq m/day was infused concurrently and continued 24 to 48 hr beyond MTX infusion. The median pretreatment serum TdR level was 0.19 micron. With...

OBJECTIVES To assess the effect of golimumab, with or without methotrexate (MTX), on serum lipids and inflammatory markers of cardiovascular disease (CVD) in patients with rheumatoid arthritis (RA) in two phase 3, randomised, placebo-controlled trials (GO-BEFORE and GO-FORWARD). METHODS Patients in GO-BEFORE (n=637, MTX-naïve) and GO-FORWARD (n=444, MTX-inadequate response) were randomised to...

Abstract A simple drug controlled delivery system is facilely designed for pH‐responsive of methotrexate (MTX), an anticancer drug. Aminated mesoporous silica nanoparticles (AMSNs) were first synthesized the loading MTX, and then MTX‐loaded AMSN (AMSN‐MTX) was encapsulated with hyaluronic acid (HA) through electrostatic attractions. Successful preparation HA‐encapsulated AMSN‐MTX (AMSN‐MTX‐HA) ...

This study was aimed to assess the protective effects of Cornus mas fruit extract (CMFE) and vitamin E (Vit E) on sperm quality parameters in the methotrexate (MTX)-treated mice. Forty-eight young adult male mice (8-12 weeks) were randomly divided into six groups including control and test groups. The control group received normal saline orally , and the test groups were treated MTX (20 mg kg(-...

Therapeutic and toxic response to low-dose methotrexate (MTX) in the treatment of autoimmune disease continues to be highly variable, resulting in a critical need to identify predictive biomarkers of response. Biomarker development has been hampered by an incomplete understanding of the molecular pharmacology of low-dose MTX. To address this issue, accumulation of the substrates for aminoimidaz...

BACKGROUND & AIMS Increased intestinal permeability occurs during chemotherapy-induced intestinal mucositis. Previous data suggest that glutamine and arginine may have additive or synergic effects to limit intestinal damage. The present study aimed to evaluate the effects of glutamine and arginine, each alone or in combination, on gut barrier function during methotrexate (MTX)-induced mucositis...

OBJECTIVE The aim of this study was to compare efficacy outcomes of initial treatment with adalimumab + MTX vs adalimumab addition following 26 weeks of MTX monotherapy in Japanese early RA patients naive to MTX with high disease activity. METHODS Patients completing the 26-week, randomized, placebo-controlled trial of adalimumab + MTX were eligible to receive 26 weeks of open-label adalimuma...

The ATP-binding cassette (ABC) transporters ABCC2 [multidrug resistance-associated protein (MRP) 2], ABCC3 (MRP3), and ABCG2 (breast cancer resistance protein) are involved in the efflux of potentially toxic compounds from the body. We have shown before that ABCC2, ABCC3, and ABCG2 together influence the pharmacokinetics of the anticancer and antirheumatic drug methotrexate (MTX) and its toxic ...
