Methotrexate (MTX) is a folate antagonist widely used both as an anticancer drug and as an immunosupressant. Administration of an 8-day methotrexate and folinic acid regime may be associated with pleuritic chest pain and pneumonitis. We have reviewed the toxicity seen in 168 consecutive patients treated with low-dose MTX for persistent trophoblastic disease. Twenty-five per cent of patients developed serosal symptoms, pleurisy was the commonest complaint. The majority of patients had mild to moderate symptoms which were controlled with simple analgesia and did not necessitate a change in treatment; 11.9% had severe symptoms which necessitated a change in treatment. One patient developed a pericardial effusion and a second patient developed severe reversible peritoneal irritation. The possible aetiology and pathophysiology of methotrexate-induced serosal toxicity is discussed.

Oral mucositis occurs in up to 75% of recipients of high-dose chemoradiotherapy conditioning regimens used for allogeneic hematopoietic stem cell transplantation (HSCT). As a result of mucositis, narcotic analgesia and total parenteral nutrition (TPN) are commonly required after HSCT. Methotrexate, an antiproliferative graft-versus-host disease (GVHD) prophylaxis agent, impairs mucosal regeneration and worsens and prolongs mucositis. We assessed the effect of substituting sirolimus for methotrexate as GVHD prophylaxis on outcomes associated with mucositis. Two patient cohorts undergoing allogeneic HLA-matched related donor peripheral blood stem cell transplantation with cyclophosphamide/total body irradiation conditioning were prospectively analyzed for mucositis severity and retrospectively reviewed for correlative outcomes. GVHD prophylaxis consisted of sirolimus/tacrolimus (ST) in the study group and tacrolimus/methotrexate (TM) in the control group. Thirty patients received ST and 24 patients received TM as GVHD prophylaxis between October 2000 and May 2003. Mild, moderate, and severe mucositis was noted in 37%, 57%, and 7% of the ST group and 8%, 42%, and 50% of the TM group (P = .0002). Less TPN was used in the ST group than the TM group (17% versus 43% of posttransplantation hospital days; P = .02). The total number of narcotic days was lower in the ST group in comparison with the TM group (median, 13.5 versus 17 days; P = .08). The time to first hospital discharge was shorter in the ST group compared with the TM group (median, 18 versus 22 days; P = .07). The substitution of sirolimus for methotrexate as GVHD prophylaxis is associated with a reduction in mucositis severity. As a result, TPN and narcotic use are reduced, and hospitalization duration is shortened. Less toxic GVHD prophylaxis regimens without methotrexate may have a significant effect on patient quality of life, patient outcomes, and economic outcomes associated with allogeneic stem cell transplantation.

Allogeneic BMT was performed in a 33-year-old man because of CML. Donor was his HLA-identical brother. GVHD prophylaxis consisted of short-term MTX and i.v. CsA. On day 17 cutaneous GVHD grade-III developed and high-dose methyl-prednisone was added. Initial daily dose of CsA was 4 mg/kg i.v. CsA dosage was adapted to maintain blood trough levels between 200 and 350 ng/ml. On day 27 the patient developed severe musculoskeletal pain of knees, legs, feet, hands, shoulders and ellbows. Only high-dose opioids and dextropropoxyphen were effective for analgesia. Additional medication besides CsA consisted of parenteral nutrition, steroids and antibiotics for total intestinal decontamination. Clinical and radiological examinantion revealed no causes for musculoskeletal pain. Serum levels for lactate-dehydrogenase, aldolase, alkaline-phosphatase, creatinphosphokinase with isoenzymes, electrolytes including magnesium were within normal ranges. Pain decreased within 4 days after switching, from intravenous to oral application. This case indicates that CsA in high dosage given intravenously combined with steroids can cause severe musculoskeletal pain as side effect in allogeneic BMT.
