Abstract

Objective Lymphocytes are a contributor to the pathogenesis of anti-neutrophil cytoplasm antibody (ANCA) associated vasculitis (AASV). Conventional immunosuppressive therapy is associated with high rates of relapse and toxicity. Humanised monoclonal anti-CD52 antibodies (alemtuzumab, CAMPATH-1H) selectively deplete lymphocytes. We present long-term follow-up results of patients with relapsing/refractory AASV treated with CAMPATH-1H.Patients and methods Between 1991 and 1999, 71 patients with refractory or relapsing AASV received CAMPATH-1H at Addenbrooke's Hospital, Cambridge, UK. Other immunosuppressive drugs were discontinued and prednisolone was tapered to 10 mg/day.Results The mean follow-up time was 5 years. In all, 79% had previously received cyclophosphamide (median dose 150 g). At the time of treatment, 42% had renal involvement (median creatinine for the cohort 101 micromol/litre excluding six patients who were dialysis dependent) and 18% were critically ill from AASV and required the intensive care unit. A total of 60 patients (85%) obtained a remission after treatment with CAMPATH-1H but 43 relapsed (median 9.2 months); 24 had a remission greater than 1 year, of which 10 had a remission of at least 3 years. A total of 31 patients died (median survival time of 106 months). Age >50 years, dialysis dependency and the development of a severe infection at the time of treatment were associated with an increased risk of death in multivariable analysis. Adverse events were common; 28 patients developed an infection, 3 malignancy and 8 thyroid disease.Conclusions CAMPATH-1H induced remission in most patients with difficult to treat AASV. However, relapse and adverse events were common. Further study of CAMPATH-1H as an induction agent in AASV is warranted.

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.
