- W2078451741 abstract "We aimed to characterize the spectrum of liver enzyme test (LET) abnormalities that occur while using methotrexate for inflammatory bowel disease (IBD).A retrospective review was undertaken of subjects using methotrexate for IBD at a single center. The clinical and epidemiological parameters, and hepatotoxicity risk factors, were recorded. Subjects were excluded if cumulative methotrexate doses could not be ascertained, if they had a diagnosis of rheumatoid arthritis or psoriasis, or if baseline and follow-up LETs were not available. Also noted were the cumulative methotrexate dose during the peak LET increase, severity of LET increase, and whether normalization occurred.Eighty-seven subjects were included (Crohn's disease, n=67; UC, n=17; indeterminate colitis n=3). The mean therapy duration was 81 weeks (3- to 364-week range), and the cumulative average dose was 1,813 mg (25-8,255-mg range). Thirty-seven (43%) subjects received a cumulative dose >1,500 mg. Sixty-seven (77%) had normal LETs, and in 51 (76%) LETs remained normal throughout methotrexate therapy. In the 16 (24%) who developed LET abnormalities, seven (44%) had underlying risk factor(s) for liver disease. Normalization (without dose reduction) occurred in 14 (88%) while continuing methotrexate. Of 20 subjects with abnormal LETs at baseline, nine (45%) subsequently normalized while continuing methotrexate, whereas nine (45%) worsened. Seventeen liver biopsies were performed in 11 and were classified as Roenigk's grade I in 15 (88%) subjects. Roenigk IIIb or IV was not seen.Methotrexate is commonly associated with LET abnormalities, but these frequently normalize while still on therapy, and in only 5% will drug discontinuation be necessary. Liver biopsies rarely have substantive abnormalities." @default.
