Iodine-induced hyperthyroidism--an epidemiological survey several years after institution of iodine prophylaxis in Poland.
In 1997, the obligatory model of iodine prophylaxis was introduced in Poland in order to correct the existing status of mild and/or moderate iodine deficiency. In order to monitor possible side-effects of increased iodine supply, studies on iodine-induced hyperthyroidism were initiated by establishing several regional registers of hyperthyroidism. In the present paper, the results of a two-year monitoring (2000-2001) have been summarized. There are no epidemiological data on hyperthyroidism prior to starting the iodine prophylaxis, but the obtained current data are comparable to observations in other countries, made after iodine supplementation. The incidence of iodine-induced hyperthyroidism did not exceed the acceptable level, thus confirming--together with previous observations on the effectiveness of iodine prophylaxis--the adequacy of applied dose of KI (30 microg/kg NaCl), used for salt iodization in Poland.
