Coeliac disease, vasculitis, and cryoglobulinaemia.
Four patients are described with the association of adult coeliac disease, vasculitis, and cryoglobulinaemia. In each patient the cryoglobulinaemia was of the mixed type consisting of more than one immunoglobulin class. It is suggested that the mixed cryoglobulins represent circulating immune complexes and that their deposition in small vessels causes the vasculitis. This is supported by immunofluorescent studies of skin biopsies from one of these patients. The significance of these findings in the four adult coeliac patients is discussed.
