Celiac disease has been associated with a number of immune-mediated hematologic disorders, including idiopathic or immune thrombocytopenic purpura (ITP). Review of the literature suggests that children are particularly affected, often with overt skin findings, but in this report, a 39-yr old male with biopsy-defined celiac disease was detected with a persistent immune-mediated reduction in his platelet count despite treatment and follow-up for more than a decade. Although the celiac disease resolved with a strict gluten-free diet, there was no effect on the ITP. Experience suggests that ITP may be rarely appreciated in adults (compared to children) because it may be limited in severity and occurs without clinically obvious purpura or evidence of bleeding, even with diagnostic or therapeutic biopsy procedures. A subsequent retrospective review of over 300 celiac disease patient records from a single teaching hospital clinical practice experience spanning almost 40 years confirmed no additional cases of thrombocytopenia. ITP appears to be rarely associated with celiac disease in adults and, in spite of resolution of the enteropathy, did not appear to respond to a gluten-free diet, even after more than a decade of dietary treatment.
