Abstract

OBJECTIVE: To perform a systematic literature review of the long-term safety of methotrexate (MTX) monotherapy in rheumatoid arthritis (RA). METHODS: A search was performed in Medline, Cochrane and EMBASE. Adults with RA who had received MTX monotherapy for more than 2 years were studied. RESULTS: 88 published studies were included. Over 12 years of treatment, the termination rate of MTX due to toxicity was less than for sulfasalazine, gold, d-penicillamine and higher than for hydroxychloroquine (level of evidence 2a-2b). Long-term use of MTX does not appear to be a risk factor for serious infections, including herpes zoster (2b-4), and could provide a survival benefit by reducing cardiovascular mortality (2b). The prevalence of raised liver enzymes (more than twice the upper limit of normal) is close to 13% of patients; 3.7% of patients stopped MTX permanently owing to liver toxicity (2b). Data on the risk for liver fibrosis/cirrhosis are conflicting: a meta-analysis showed an incidence of fibrosis of 2.7% after 4 years of MTX (2a). However, two other studies on sequential liver biopsies did not show evidence for developing severe damage (2b). Insufficient data are available to fully assess the risk of lymphoma and malignancies, although there is no strong evidence of increased risk (2b-4). CONCLUSION: This systematic literature search on MTX monotherapy with relatively low-dose use during at least 2 years shows favourable long-term safety.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
