✦ Synopsis


Two common cross-reacting anti-DNA antibody idiotypes designated 1616 and 32/15, previously identified in the serum of patients who have systemic lupus erythematosus, were found in 24% and 7%, respectively, of 147 first-degree relatives. These findings imply that high-frequency germ-line genes exist among lupus relatives, as well as patients. These dominant or public anti-DNA antibody idiotypes are not likely to be pathogenic factors, but are probably a genetically associated phenomenon.

Evidence of a genetic basis for systemic lupus erythematosus (SLE) has been accumulated in a variety of studies. Population studies have indicated a particular predominance of black females (I), while

## Abstract Serum C3, C4, and total hemolytic complement (CH50) levels were measured for 21 children with systemic lupus erythematosus (SLE) and 81 first degree relatives. The mean serum C4 and CH50 levels of the 12 relatives with antinuclear antibodies (ANA) were depressed to levels equal to those

An anti-double-stranded (ds) DNA antibodies in serum-detection system was developed based on flow immunoassay with packed-capillary column. Alkaline phosphatase conjugated DNA (ALP-DNA) and anti-dsDNA antibody were separated from unreacted ALP-DNA on the basis of the difference in isoelectric point.
