摘要
Background: There is a paucity of studies regarding oxidative balance and selenium (Se) status in congenital hypothyroidism. Recently, more attention has been given to the use of Se supplementation as a new treatment for thyroid disorders. Oxidative stress increases in different thyroid disorders and causes many pathological outcomes. The present study aimed to determine the serum prooxidant-anti-oxidant balance (PAB), Se, thyroid stimulating hormone (TSH) and free thyroxine (FT4) concentration in congenital hypothyroidism (CH) patients and the association of their probable change with hematological indices.
Methods: Blood samples were collected from 60 healthy and 39 CH subjects. Serum PAB values were measured and Se, TSH, FT4 and hematological indices were determined. Data were analyzed by SPSS version 16 and p value less than 0.05 was considered statistically significant.
Results: Serum TSH concentration was significantly higher in CH patients group compared to the controls (p value < 0.05); however, FT4 was in the same concentration in patients and controls. Platelet (Plt) and lymphocytes (Lym) counts markedly decreased in all patients and showed a significant direct correlation with serum TSH levels (r(s) = 0.307, p value = 0.004 and r(s) = 0.413, p value < 0.0001). Serum PAB and Se had no significant correlation with hematological indices in the studied subjects.
Conclusions: Although there was no correlation between PAB and also Se with hematologic and biochemical markers in CH patients, changes in these two factors might be considered as a potential risk factor due to the other known effects of high PAB values and low Se concentrations.
