High Prevalence of Celiac Disease in Patients with Immune Thrombocytopenia
- 24 Downloads
Celiac disease (CD) is known to be associated with several autoimmune disorders. We studied the prevalence of subclinical CD among patients with immune thrombocytopenia (ITP) as compared to general population. Cases of primary ITP between the age group of 18–60 years were studied. Besides clinical examination, all patients underwent serology testing for tissue transglutaminase antibody (tTG) IgA and anti-endomysial antibodies IgA. The diagnosis of CD was made if both antibodies were positive. Healthy subjects acted as controls and underwent serological testing for tTG IgA. Seventy-nine primary ITP and 316 healthy subjects underwent serology testing for CD. Four patients of primary ITP (4/79) were positive for both serology as compared to 2 (2/316) healthy controls [odds ratio 8.37 (CI 1.50–46.47, p < 0.005)]. Among the ITP cases only one had clinical symptoms of CD while none of the healthy controls had symptoms of CD. There is a significantly higher prevalence of subclinical CD in patients with ITP. Since the prevalence of CD is known to vary among different geographical zones, we suggest further studies on screening of ITP patients for CD in areas of high prevalence.
