INVESTIGATION THE EFFECT OF HYPOTHYROIDISM ON HEMATOLOGICAL PARAMETERS HİPOTİROİDİNİN HEMATOLOJİK PARAMETRELER ÜZERİNE ETKİSİNİN İNCELENMESİ

Aim: To investigate impact of the hypothyroidism on hematological parameters. Material and Method: Twenty patients with hypothyroidism and twenty two healthy subjects were enrolled in this study between February 2015 and July 2015. We collected clinical and laboratory data of patients with hypothyroidism and randomized healthy subject’s from the Adiyaman University Medical Faculty Hospital records retrospectively. The patients with anemia, rheumatic diseases, chronic kidney diseases, chronic liver diseases, chronic obstructive pulmonary disease, chronic heart diseases, inflammatory bowel diseases, malignancy and acute infections were excluded from the study. Patients were divided into two groups; hypothyroid group and healthy group. TSH values were increased in all of the hypothyroid patients. We compared hematological parameters consist of hemoglobin, platelet count, white blood cell (WBC), red cell distribution width (RDW) and mean platelet volume (MPV) between the two groups. Results: 70% of patients with hypothyroidism were female and 30% of patients were male. Mean age of patients with hypothyroidism were 44,8±13,4. 72,7% of  healthy subjects were female and 27,3% of healthy subjects were male. Mean age of healthy subjects was 31±14,6. In the result with Independent sample T test increased RDW-CV values was significantly associated with hypothyroidism ( P value =0.01). The other hematological parameters weren’t different between the groups ( P value >0.05). Conclusion: The present study demonstrated that increased RDW values was associated with hypothyroidism.
