UNLABELLED: Autoimmune thyroiditis (AIT) is characterised by infiltration of lymphocytes and destruction of thyroid gland. It results from the interaction of genetic predisposition and environmental triggers. Among environmental factors some infections, medications and inadequate micronutrients supply like selenium (Se) deficiency are believed to play a role.
AIM: The aim of our study was to assess the serum selenium concentration in patients with AIT and healthy volunteers in the Polish population living in the Poznan district, and to compare our results with similar trials conducted on other European AIT groups.
MATERIALS AND METHODS: Fifty three patients with AIT were included in the study. Elevated thyroperoxidase antibodies and/or thyroglobulin antibodies concentration and abnormalities typical for AIT in the thyroid ultrasound were the inclusion criteria. A control group consisted of 36 healthy, age and sex-matched volunteers.
RESULTS: The median Se concentration was 56.67 μg/L in the AIT group and 39.75 μg/L in the controls (p>0.05). Decreased Se concentration was observed in 62% of the patients and in 72% of the controls (p=0.47). There was no statistically significant difference in Se status in AIT group when compared to the other Polish, German, Austrian, Dutch and Greek populations with AIT. Significantly higher values were observed in Italian and Greek study when compared to present results in AIT group.
CONCLUSIONS: No association between selenium status and prevalence of autoimmune thyroiditis in Polish population living in Poznan district was noticed. Nevertheless determination of the normal serum Se concentration for European populations is necessary. Further studies with enlarged studied groups should be implemented.
