The result of thyroid function test, thyroid autoantibodies, Coombs' reactivity, anti-nuclear antibody, and double-stranded DNA were analyzed. This study was conducted in the Clinical Hematology Department, King Abdulaziz University Hospital, Jeddah, Saudi Arabia between June 2003 and August 2010.RESULTS: There were 51 (36.2%) patients with laboratory evidence of autoimmune disease, 13 (9.2%) with hypothyroidism, and 6 (4.3%) with hyperthyroidism. In addition, 5 (3.5%) patients showed laboratory evidence of Evan syndrome and 3 (2.1%) patients had isolated positive thyroid antibodies. There was non-significant difference (p=0.61) in platelets count after one month of treatment of patients with different thyroid condition.CONCLUSIONS: Immune thrombocytopenia is associated with evidence of different autoimmune disease or a combination of them, which may appear at presentation or during the course of disease giving evidence that they are different manifestations of a single disease. Screening patients for antithyroid antibodies would identify a patient at risk of developing overt thyroid disease. These patients may be further screened with a thyroid-stimulating hormone assay to detect subclinical thyroid disease. ER -
