Abstract

Aims: To investigate celiac disease (CD) and related co-morbidity in patients with familial and sporadic cardiomyopathy and in their relatives. Methods and results: We screened anti-human-tissue-transglutaminase (IgA and IgG anti-h-tTG) and anti-endomysial antibodies (AEAs) in 238 consecutive adult patients with inherited or sporadic dilated cardiomyopathy (DCM), 418 relatives, and 2000 healthy blood donors. HLADQ2-DQ8 was tested in tTG-positive subjects. The IgA-tTG-positive patients with cardiomyopathy underwent duodenal biopsy. Twenty-six subjects were tTG-positive: five DCM patients (2.1%), two of 28 (7.1%) and three of 390 (0.7%) relatives with and without echocardiographic abnormalities respectively, and 16 controls (0.8%). Twenty-two of 26 subjects were AEA-positive, and 25 HLA-positive. Of the five patients with cardiomyopathy and biopsy-proven CD, four suffered iron-deficiency anaemia. Two CD-positive DCM patients and two tTG-positive relatives were from families with inherited disease in which CD did not co-segregate with DCM. Conclusions: The higher prevalence of CD in patients with sporadic or inherited DCM, and of tTG-positive serology in relatives with echocardiographic abnormalities, suggests that immune-mediated mechanisms are active in subsets of patients/families. However, gluten intolerance cannot be considered causative since CD seems to be associated but not co-segregated with DCM in familial cases.
