Implication of Rs7975232 and Rs1801274 Gene Polymorphisms in the Risk and the Prognosis of autoimmune Thyroid Diseases in the Tunisian Population.

Hashimoto's thyroiditis (HT) and Graves' disease (GD) are autoimmune thyroid diseases (AITD) that cause hypothyroidism and hyperthyroidism, respectively. The vitamin D receptor (VDR) and the Fey receptor IIA (FcγRIIA), are implicated in the etiology of AITD. This study was conducted to examine the implication of rs7975232 and rs 1801274 variations in the susceptibility and the prognosis of AITD in the Tunisian population.

Polymorphisms in TSHR gene and the risk and prognosis of autoimmune thyroid disease in Tunisian population.

Background: Autoimmune thyroid diseases (AITD) including Graves' disease (GD) and Hashimoto's thyroiditis (HT) are complex genetic diseases. TSHR is considered as candidate gene in GD. This finding prompted us to investigate the association of TSHR gene polymorphism with the risk and the prognosis of AITD in Tunisia.

Association of cytokine Th2 gene polymorphisms with autoimmune thyroid diseases in Tunisian population.

Autoimmune thyroid diseases (AITD) including Graves' disease (GD) and Hashimoto's thyroiditis (HT) are complex genetic diseases. Th2 cytokines act on the development of AITD. This study was conducted on Tunisian patients with AITD to investigate the association of Th2 cytokine gene polymorphisms and haplotype combination with GD or HT risk.

Pro- and anti-angiogenic VEGF mRNAs in autoimmune thyroid diseases.

The aim of this study was to assess the relationships between five different splice isoforms of VEGF mRNA and its plasma levels in individuals treated for autoimmune thyroid diseases (AITD); mainly Graves' disease (GD) and Hashimoto's thyroiditis (HT). In a population from Tunisia, levels of thyroid hormones and antibodies were quantified simultaneously with plasma VEGF and VEGF mRNA isoforms after a period of 6 months of patients' treatment. Plasma VEGF was measured in 110 AITD patients (21 GD and 89 HT patients).

Association of Interleukin-1B and Interleukin-4 Gene Variants with Autoimmune Thyroid Diseases in Tunisian Population.

Autoimmune thyroid diseases (AITD) including Graves' disease (GD) and Hashimoto's thyroiditis (HT) are complex genetic diseases. Cytokines IL-1B and IL-4 play a role in the pathogenesis of AITD. This study was conducted on Tunisian patients with GD or HT to investigate the association of IL-1B and IL-4 gene polymorphisms with the risk and the prognosis of AITD.
