Relationship between primary hypothyroidism and hyperuricemia:an investigation / 军事医学

ABSTRACT

Objective To explore the relationship between primary hypothyroidism and hyperuricemia and to speculate their possible mechanism .Methods The levels of FT3 ,FT4 ,TSH, Anti-TG ,Anti-TPO, TRAb, UA, TC, TG, LDL-C, HDL-C,Hcy, Cys,β2 MG and 24hUA were measured in 36 patients with hypothyroidism , compared with 20 healthy sub-jects.According to the absence or presenceof Anti-TG, Anti-TPO and TRAb, the patients were divided into two sub-groupsthe Hashimo to(HT) hypothyroidism group (27 cases) and the non-HT hypothyroidism group (9 cases)before they were compared with each other .Results Compared with healthy subjects , patients with hypothyroidism had higher TSH , TC,TG, LDL-C, UA, Hcy,Cys,andβ2MG,and lower FT3,FT4,HDL-C,and 24hUA.The difference was significant (P<0.05);the thyroid function, autoimmune antibodies, TC, LDL-C, UA and 24hUA were also significantly differen between the two sub-groups.Conclusion Patients with hypothyroidism are more prone to hyperuricemia , which may be related to decreased thyroid hormone , lipid metabolism disorder and hyperhomocysteine .The level of UA is higher in HT hypothyroidism than in non-HT hypothyroidism , indicating that autoimmune factors may be involved in the occurrence of hyperuricemia .
