Screening for congenital hypothyroidism in Turkey.
A pilot study was performed to determine the incidence of congenital hypothyroidism (CH) in Turkey and to build a model for nationwide screening.
From December 1991 to December 1992,30097 newborns were screened for CH using a primary measurement of thyroid stimulating hormone in capillary blood on days 3-5 of life.
Samples were obtained in collaboration with the ongoing nationwide phenylketonuria screening programme.
Eleven cases of primary CH were detected giving the incidence of 1 : 2736.
Recall rate was 2.3%. Replacement therapy with L-thyroxine was started after the confirmation of diagnosis.
The median age at the initiation of replacement therapy was 23 days (range 7-35 days).
Conclusion The incidence of CH is notably higher in Turkey than reported in most other countries.
Iodine deficiency and/or dyshormonogenesis might contribute to this high incidence.
This result emphasizes the necessity of a nationwide screening programme.
