Systemic lupus erythematosus in patients with chronic cutaneous (discoid) lupus erythematosus. Clinical and laboratory findings in seventeen patients.

The presence of the discoid lupus erythematosus (DLE) skin lesion in a patient with systemic lupus erythematosus (SLE) has been suggested to be a marker of less frequent and less severe renal disease. The clinical and laboratory features of seventeen patients who were seen in a dermatology practice and who had DLE as a manifestation of SLE (DLE-SLE) are reported. DLE preceded the diagnosis of SLE in eight patients. In six patients, the onset was concurrent, whereas in three the SLE was present prior to the discoid skin lesions. Five of the patients had lesions of subacute cutaneous lupus erythematosus (SCLE), and Raynaud's phenomenon occurred in eight patients. Clinical evidence of a renal abnormality was present in six patients (hematuria in three, proteinuria in five, and abnormal renal function in two). Antibodies to nuclear and/or cytoplasmic components were abnormal in all patients. Antibody subsets did not correlate well with clinical findings; only half of those with Raynaud's phenomenon demonstrated a positive ribonucleoprotein; only one patient with SCLE demonstrated anti-Ro (SSA) antibody, but four of the six patients with a renal abnormality had an elevated anti-native deoxyribonucleic acid antibody titer. The cutaneous lesions were eventually widespread in all patients, although two had initial disease that was localized to the head and neck. Although renal disease occurs in this group, it is less common and usually milder than in previous groups of unselected SLE patients.

Defective degradation of bacterial DNA by phagocytes from patients with systemic and discoid lupus erythematosus.

The digestion of bacterial DNA by peripheral blood monocytes was impaired both in patients with systemic lupus erythematosus (SLE) and discoid lupus erythematosus (DLE). The monocytes of these patients had both a small quantitative defect in the solubilization of DNA and a marked qualitative defect in the extent to which this DNA was degraded. In addition, neutrophils from patients with SLE released significantly less high molecular-weight DNA than control cells. Digestion of bacterial RNA and protein by phagocytes was not defective in either disease. The reduced digestion of DNA by phagocytes resulted in concomitantly larger amounts of high molecular-weight DNA remaining in these cells. Such sequestration of DNA may contribute to the persistence of fairly large DNA fragments in the tissue of patients with lupus erythematosus.
