ABSTRACT

Aim: Macroprolactin is a high-molecular-weight form of prolactin. It has been suggested that macroprolactin has no clinical importance because of its decreased or limited bioactivity. Although screening for macroprolactinemia is recommended especially in patients with idiopathic hyperprolactinemia; recent studies reported that patients with macroprolactinemia may have some hyperprolactinemia symptoms. Currently, the causes of the symptoms as well as the treatment and follow-up of this group of patients are not clear. In our study, we aimed to retrospectively evaluate and compare the clinical characteristics and gonadal hormone levels of patients with macroprolactinemia and hyperprolactinemia.
Materials and Methods: Forty patients with macroprolactinemia and 15 patients with hyperprolactinemia who referred to Obstetrics and Gynecology Hospital were examined.
Results: We observed that the patients with macroprolactinemia had similar menstrual disturbances (oligomenorrhea/amenorrhea) to the patients with hyperprolactinemia. There was no statistically significant difference between the two groups with respect to FSH, LH and estradiol levels. The frequencies of galactorrhea (p=0.002), headache (p=0.04) and positive radiological finding (p=0.001) were higher in patients with hyperprolactinemia. Infertility rate was found to be increased in women with macroprolactinemia (p=0.02).
Conclusion: Patients with macroprolactinemia may have very similar clinic symptoms to  those with hyperprolactinemia. Therefore, macroprolactin levels should be measured regardless of the symptoms of hyperprolactinemia in patients with elevated prolactin levels.
