Immunologic Factors and Clinical Activity in Systemic Lupus Erythematosus

Schur, Peter H., Sandson, John·1968·New England Journal of Medicine

Abstract

To clarify the association between certain immunologic factors and clinical activity in patients with systemic lupus erythematosus, 96 patients were studied. Those with antibodies to deoxyribonucleic acid (DNA) or heat-denatured DNA, or with serum complement levels of less than 50 C′H50 units per ml, were more likely to have renal involvement. Very low complement levels and high titers of complement-fixing antibodies to DNA were always associated with active disease, especially active renal disease, whereas the absence of these abnormalities usually indicated inactive renal disease. A 50 per cent fall in serum complement levels in 22 patients was accompanied by, or preceded the onset of, active nephritis in 19 patients. These serologic factors may thus reflect the in vivo formation of immune complexes that cause nephritis. Serial immunochemical observations may be useful in the management of patients with systemic lupus erythematosus.

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.
