Lymphocytotoxic antibodies. HLA antigen associations, disease associations, and family studies.
Lymphocytotoxic antibodies (LCTAB) were sought in sera of patients with rheumatic diseases and in family members. Patients with SLE and cutaneous necrotizing venulitis and family members of JRA patients had an increased frequency of LCTAB; JRA patients and family members of SLE patients did not. The only association between LCTAB and the HLA phenotype of persons with LCTAB was a decreased frequency of LCTAB in individuals with HLA-B27.
