BACKGROUND: The clinical efficacy and safety of low-dose levothyroxine in the treatment of idiopathic nephritic syndrome accompanied by thyroid dysfunction have not been established. METHODS: One hundred and sixty-four patients were divided into three groups according to the levels of thyroid hormone and treatment. The thyroid status, efficacy and adverse reactions of thyroid treatment were observed in each group. RESULTS: Thyroid dysfunction was found in 73 patients. 40 cases were treated with steroids combined with levothyroxine. Proteinuria, cholesterol and thyroid-stimulating hormone (TSH) levels were significantly higher in patients with thyroid dysfunction, whereas serum albumin and free and total T3 and T4 levels were lower than those of euthyroid patients. The time for proteinuria remission in patients receiving levothyroxine therapy was shorter and their serum albumin higher than for patients without levothyroxine treatment. CONCLUSIONS: Thyroid hormonal changes are related to the degree of both proteinuria and serum albumin in patients with INS. Combined treatment with low-dose levothyroxine supplementation and steroids in children with INS and thyroid dysfunction is associated with reduced proteinuria and increased plasma albumin compared with patients treated with steroids only.
