The effect of Hashimoto's thyroiditis on platelets in terms of the their number, size, and distribution

Objective: The aim of our study was to investigate whether platelet indices were affected in patients with Hashimoto’sthyroiditis (HT).Method: 11 patients (10 female, 1 male) with HT and 26 subjects with nodular goiters (19 female, 7 male) selected ascontrol group were included in the study. All cases were examined for complete blood count parameters (leukocytecount, neutrophil count and percentage, lymphocyte count and percentage, platelet count, plateletcrit, plateletdistribution width (PDW), and mean platelet volume (MPV)).Results: Leukocyte count, neutrophil count and percentage, lymphocyte percentage, platelet count, plateletcrit, andMPV in the patient group were not statistically different from the control group. Lymphocyte count and PDW weresignificantly higher in patients with HT than in the control group.Conclusion: Our results suggest that patients with HT have higher PDW levels. Increased PDW in HT may be helpful indiagnosis, floow-up, and prognosis of the disease.
