Successful rescue with leucovorin and thymidine in a patient with high-dose methotrexate induced acute renal failure. Neoadjuvant chemotherapy for osteosarcoma of the extremity in patients in the fourth and fifth decade of life. Br J Cancer ; This clinical observation is supported by laboratory studies that demonstrated that reversal of MTX by LV is competitive, with relatively higher concentrations of LV required as the MTX concentration increases.

Rheumatology Research Foundation The Foundation is the largest private funding source for rheumatology research and training in the U. In addition to conventional treatment approaches, dialysis-based methods have been used to remove MTX with limited effectiveness. Delayed clearance of methotrexate in a patient with malignant lymphoma who developed renal failure.

Methotrexate and Lymphoma

Severe renal toxicity due to intermediate-dose methotrexate. Another recent study showed that antibodies, which can help diagnose rheumatoid arthritis called rheumatoid factorcan also reactivate EBV.

Published literature was reviewed from to on recovery of renal function in patients with methotrexate-induced renal dysfunction. Keywords methotrexate toxicity; renal dysfunction; hemodialysis; hemoperfusion; carboxypeptidase-G 2 ; high-dose methotrexate.

The reported peak serum creatinine concentrations were higher for the 12 patients who underwent dialysis-based methods median serum creatinine, 3.

Time dependence of prognostic factors for patients with soft tissue sarcoma Next article in issue: Continued They found that methotrexate activated the Epstein-Barr virus; the other rheumatoid arthritis medications -- including cyclosporinecyclophosphamideand prednisone -- did not markedly affect EBV activity, even when doses of these drugs were higher than normal, she reports. Nomograms guiding the duration and degree of rescue with LV based upon plasma MTX concentrations as a function of time of drug administration were developed and are being used in ongoing clinical trials that administer HDMTX Fig.

We don't always see these lymphomas immediately after they start the treatment. Cancer ; High-dose thiotepa and etoposide in children with poor-prognosis brain tumors Previous article in issue: The role of 7-hydroxymethotrexate during methotrexate anti-cancer therapy.

Some studies have indicated that the drug's immune-weakening effect places people at risk for viral-associated lymphomas.

Severe toxicity was observed in only three patients, in whom Thd was initiated 5, 12, and 13 days after the start of MTX infusion. Grade 2 toxicity 14 patientsGrade 3 1 patients ; all patients received LV, hydration, alkalinization, no dialysis, no more MTX.
