Background: Thyroid disease in pregnancy is a common clinical problem. Since the guidelines for the management of these disorders by the American Thyroid Association (ATA) were first published in 2011, significant clinical and scientific advances have occurred in the field. A major and substantial change in the new guidelines includes raising the upper limit in the normal thyroid function tests. For Thyroid Stimulating Hormone (TSH), the upper limit was 2.5 mU/L in the 2011 guidelines. Normal upper limit in pregnancy is raised to 4.0 mU/L in 2017 revision. In the present study, we evaluated our pregnant patients according to the ATA 2017 criteria. brain development is totally dependent on the maternal thyroid hormones [8]. Since congenital hypothyroidism is one of the most preventable causes of mental retardation, we insist on the necessity of frequent blood tests especially valid for the first 14 weeks. It is also vital to remember that iron and calci-

Ovarian function with regular menstrual cycles is usually restored in women of reproductive age after solid organ transplantation. The number of pregnancies reported in these patients increases gradually. Pregnancy is always considered high risk, and if not properly planned, may lead to serious complications. The best for the patient is to conceive in a period of good general health and good stable graft function, after appropriate preparation. However, hepatitis C virus (HCV) infection will be an additional risk factor in these cases. The present study was designed to review the possible risks and outcome of pregnancies in kidney transplant recipients with HCV.
