A Randomized Study of the Effect of Withdrawing Hydroxychloroquine Sulfate in Systemic Lupus Erythematosus

Open access
·1991·New England Journal of Medicine

Abstract

BACKGROUND: The antimalarial drug hydroxychloroquine is thought to be effective in controlling some of the manifestations of systemic lupus erythematosus, but its effectiveness has not been demonstrated conclusively. METHODS: We conducted a six-month, randomized, double-blind, placebo-controlled study of the effect of discontinuing hydroxychloroquine sulfate treatment in 47 patients with clinically stable systemic lupus erythematosus. The patients were randomly assigned to continue their same dose of hydroxychloroquine (n = 25) or to receive placebo (n = 22) for 24 weeks. Ten patients in each group were also taking prednisone. RESULTS: The relative risk of a clinical flare-up, defined as the development of specific clinical manifestations of systemic lupus erythematosus or an increase in their severity, was 2.5 times higher (95 percent confidence interval, 1.08 to 5.58) in the patients taking placebo than in those continuing to take hydroxychloroquine (16 of 22 patients vs. 9 of 25 had flare-ups), and the time to a flare-up was shorter (P = 0.02). The relative risk of a severe exacerbation of disease that required withdrawal from the study was 6.1 times higher (95 percent confidence interval, 0.72 to 52.44) for the patients taking placebo (5 of 22 patients vs. 1 of 25 had severe exacerbations of disease). Changes in the dose of prednisone were not different in the two groups. CONCLUSIONS: Patients with quiescent systemic lupus erythematosus who are taking hydroxychloroquine are less likely to have a clinical flare-up if they are maintained on the drug.

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.
