Summary of "The conversion of hypothyroidism into hyperthyroidism during leflunomide with povidone iodine treatment of rheumatoid arthritis."

Till now there has not been reported data related to the influence of leflunomide on the thyroid gland function of the treated person. The authors described the case of woman with rheumathoid arthritis and hypothyroidism who revealed hyperthyroidism in 7 months after starting leflunomide tablets treatment containing povidone iodine as well. Also both autonomical tissue area in thyroid right lobe and hight TSHRAb level were found. Leflunomid tablets containing povidone iodine in its structure can cause hyperthyroidism in the person with previous hypothyroidism and nodular goiter, probably as a result of immunological reconversion and tissue nodular functional autonomisation. In persons with nodular goitre one should prefer free of povidone iodine leflunomide treatment and also monitor serum thyroid hormone contents and thyroid antibodies as well.

Medical and Biotech [MESH] Definitions

Enlargement of the THYROID GLAND that may increase from about 20 grams to hundreds of grams in human adults. Goiter is observed in individuals with normal thyroid function (euthyroidism), thyroid deficiency (HYPOTHYROIDISM), or hormone overproduction (HYPERTHYROIDISM). Goiter may be congenital or acquired, sporadic or endemic (GOITER, ENDEMIC).

A thiourea antithyroid agent. Propythiouracil inhibits the synthesis of thyroxine and inhibits the peripheral conversion of throxine to tri-iodothyronine. It is used in the treatment of hyperthyroidism. (From Martindale, The Extra Pharmacopeoia, 30th ed, p534)

A condition in infancy or early childhood due to an in-utero deficiency of THYROID HORMONES that can be caused by genetic or environmental factors, such as thyroid dysgenesis or HYPOTHYROIDISM in infants of mothers treated with THIOURACIL during pregnancy. Endemic cretinism is the result of iodine deficiency. Clinical symptoms include severe MENTAL RETARDATION, impaired skeletal development, short stature, and MYXEDEMA.

A set of opposing, nonequilibrium reactions catalyzed by different enzymes which act simultaneously, with at least one of the reactions driven by ATP hydrolysis. The results of the cycle are that ATP energy is depleted, heat is produced and no net substrate-to-product conversion is achieved. Examples of substrate cycling are cycling of gluconeogenesis and glycolysis pathways and cycling of the triglycerides and fatty acid pathways. Rates of substrate cycling may be increased many-fold in association with hypermetabolic states resulting from severe burns, cold exposure, hyperthyroidism, or acute exercise.

A polyvinyl polymer of variable molecular weight; used as suspending and dispersing agent and vehicle for pharmaceuticals; also used as blood volume expander.
