Frequency of lupus flare in pregnancy: The hopkins lupus pregnancy center experience

Petri, Michelle, Howard, Denise, Repke, John·1991·Arthritis & Rheumatism

Abstract

To determine whether pregnancy is associated with an increased rate of flare in patients with systemic lupus erythematosus (SLE), we prospectively studied 40 pregnancies in 37 women with SLE. The women were evaluated on a monthly basis in the Hopkins Lupus Pregnancy Center. Flare was designated using a previously developed quantitative definition, i.e., a change of >1.0 in the physician's global assessment (scale of 0–3) since the preceding visit or during the last 93 days. Flare occurred in 24 (60%) of the pregnancies. Flares presented most commonly as constitutional symptoms, renal involvement, or involvement of skin or joints. Comparison of the rates of flare in the same patients after delivery and in nonpregnant SLE patients showed a significant increase in the rate of flare during pregnancy (P <0.001 and P <0.0001, respectively). We conclude that flare of lupus during pregnancy is common and occurs significantly more frequently than does flare in nonpregnant SLE patients or in the same patients after pregnancy.

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.
