Abstract

OBJECTIVE: To define the rate, timing, and clinical risk factors for the development of autoimmune disease (AID) after alemtuzumab treatment for multiple sclerosis (MS). METHODS: We analyzed prospective clinical and serologic data from 248 patients with MS treated with alemtuzumab, with median follow-up of 34.3 months (range 6.7-107.3). RESULTS: Novel AID developed in 22.2%. Thyroid AID was most frequent (15.7%). A range of hematologic, renal, and dermatologic AID were also observed as was asymptomatic development of novel autoantibodies. AID was seen from 2 weeks after initial treatment and was most frequent 12-18 months after first treatment. No new cases of AID were identified 60 months or more after initial treatment and risk of AID was independent of total alemtuzumab dose or interval of dosage. While established risk factors for AID including sex and age had no impact on AID frequency, both family history (odds ratio = 7.31, 95% confidence interval 3.02-17.68) of AID and a personal smoking history (odds ratio = 3.05, 95% confidence interval 1.50-6.19) were predictive of AID expression. CONCLUSIONS: Cumulative risk for AID in MS following alemtuzumab is 22.2%, most frequent between 12 and 18 months following first dose and evident for up to 5 years. Individual risk is modified by smoking and family history, which should be incorporated within the counseling process prior to treatment. CLASSIFICATION OF EVIDENCE: This study provides Class IV evidence that the risk of AID after alemtuzumab treatment for MS is time-limited and modified by external factors.

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.
