title: [Absence of antiDNA antibodies in the cryoglobulins of a case with sicca syndrome (author's transl)].
abstract: Cryoglobulins are serum immunoglobulins (immunocomplexes) that precipitate in the cold and redissolve on warming. Cryoglobulins from patients with several diseases showed the presence of antiDNA antibodies when previously underwent incubation in acid buffer. The possibility that antiDNA antibodies might constitute the immunocomplexes found in patients with systemic lupus erythematosus and with other connective tissue diseases is suggested. Negative findings in relation to the presence of antiDNA antibodies in cryoglobulins of a case with sicca syndrome are reported.
