Hyperthyroidism affects approximately 1.2% of the population and its routine treatment includes antithyroid drugs (ATDs), radioiodine and surgery. Management of patients with resistance or contraindications to ATDs who require thyroidectomy may be challenging. We present the experience of our department in preparing thyrotoxic patients for life‐saving thyroidectomy by using therapeutic plasma exchange (TPE) with albumin: one patient with Graves' disease and previous history of agranulocytosis and cholestatic jaundice after ATDs and two patients with amiodarone‐induced thyrotoxicosis. Five to six TPEs were applied to each patient resulting in a decrease of fT3 by 57% to 83%, fT4 by 21% to 60% and decrease/normalization of total thyroid hormones. All patients underwent surgery successfully. In case of drug‐resistant thyrotoxicosis or contraindications to ATDs, TPE can be a valuable tool in preparing patients for surgery. Albumin used as a replacement fluid appears to be effective in ameliorating clinical and laboratory symptoms of thyrotoxicosis.

Thyroid autoimmunity (TAI) is commonly defined as the presence of thyroperoxidase antibodies (TPOAbs) and/or thyroglobulin antibodies (TgAbs), which predisposes an individual to hypothyroidism. TAI affects nearly 10% of women of reproductive age and evokes great interest from clinicians because of its potentially negative impact on female fertility and pregnancy course. In this mini-review, we review the current literature concerning the influence of TPOAb or TPOAb/TgAb positivity without thyroid dysfunction on reproduction. TAI may negatively affect female fertility; several studies have found an increased prevalence of TAI in infertile women, especially in those with unexplained infertility and polycystic ovary syndrome. According to some observations, TAI might also be connected with premature ovarian insufficiency and endometriosis. The relationship between TAI and an increased risk of pregnancy loss is well documented. The pathophysiological background of these observations remains unclear, and researchers hypothesize on the direct infiltration of reproductive organs by thyroid antibodies, co-existence of TAI with other autoimmune diseases (either organ specific or systemic), immunological dysfunction leading to inhibition of immune tolerance, and relative thyroid hormone deficiency. Interestingly, in the current literature, better outcomes of assisted reproductive technology in women with TAI have been reported compared with those reported in earlier publications. One plausible explanation is the more widespread use of the intracytoplasmic sperm injection method. The results of randomized clinical trials have shown that levothyroxine supplementation is ineffective in preventing adverse pregnancy outcomes in women with TAI, and future research should probably be directed toward immunotherapy.
