Prevalent Practices of Thyroid Diseases During Pregnancy Among Endocrinologists, Internists and General Practitioners

Maternal thyroid disease in pregnancy is associated with adverse impact on both mother and fetus. Both the American thyroid association and the endocrine society have recently published guidelines for the management of thyroid disease in pregnancy.. The objective of this survey was to assess and compare the current practices of various East-Asian physicians in the screening and management of thyroid disease in pregnancy.. Completed survey questionnaires were collected from 112 physicians of six East-Asian countries. The survey was based on clinical case scenarios, asking questions about the clinical practices related to diagnosis and management of thyroid disease during pregnancy. Reponses from 76 endocrinologists and 33 internists and general practitioners (generalists) were analyzed.. There were minor differences in treatment preferences for Graves’ disease in pregnancy and tests to monitor antithyroid drugs between endocrinologists and generalists; the major difference being targeted free thyroxin, and also thyroxin, depicted in the upper end of normal range, by the majority of endocrinologist and within the normal range, by generalists. Compared to generalists, endocrinologists perform more targeted screening and are more familiar with its risk factors. Predominantly, endocrinologists increase levothyroxine dose in hypothyroid women, upon confirmation of pregnancy and also indicate full dose in a pregnant woman, diagnosed with overt hypothyroidism, and treat thyroid peroxidase antibody positive or negative pregnant women with thyroid stimulating hormone (2.5 - 5 mU/L), as compared to generalists.. There is wide variation in the clinical practices of screening and management of thyroid disorders during pregnancy in East-Asia, with many clinicians, in particular general practitioners, not adhering to clinical practice guidelines, unfortunately..
