Abstract :

Background: Hyperthyroidism is less common than hypothyroidism in pregnancy. A rare cause of thyrotoxicosis during pregnancy is gestational trophoblastic disease (GTD).

Aims/Objectives : To perform thyroid function testing in two suspected cases of GTD and its follow up.

Material Methods: Two patients of GTD presented for β hCG and TFT measurement, which were estimated by chemiluminescent immunoassay.

Results: First case had β hCG levels 2,34,000 and TFT (TSH = 0.06μIU/ml, FT4 = 1.97 ng/dl, FT3 = 5.16 pg/ml) and second case had β hCG 2,76000 with TFT (TSH – 0.07 μIU/ml; FT4 = 2.14ng/dl; FT3 = 4.34pg/ml). TFT and β-hCG was repeated after suction evacuation. They remained elevated and normalised at 5^thday in case one while it took 2 weeks to normalise in case two.

Conclusion: The development of hyperthyroidism is largely influenced byhCG level and usually resolves with treatment of GTD. Hyperthyroidism in pregnancy should be diagnosed early and managed efficaciously before suction evacuation of hydatidiform mole.
