IgG subclasses of anti-double-stranded DNA antibodies were determined in 182 patients with systemic lupus erythematosus. All isotypes were detected, but IgG1 and IgG3 were predominant (62 and 51% of the cases, respectively). An average of 64 +/- 27% was IgG1, 16 +/- 22% IgG2, 16 +/- 19% IgG3 and 4 +/- 10% IgG4. The rank order or frequency was IgG1, IgG3, IgG2 and IgG4 in patients with musculoskeletal involvement; IgG1, IgG2, IgG3 and IgG4 in those with renal complications; IgG3, IgG1, IgG2 and IgG4 in those with cutaneous involvement; and IgG1, IgG3, IgG2 and IgG4 in those with hematological manifestations. Interleukin-4 (IL-4) was detectable in 17 of 36 selected patients, as opposed to 1 of 40 normal controls. The percentage of the total autoantibody contributed by IgG1 was significantly higher (p < 0.03) in these patients than in the remainder with undetectable levels of IL-4.
