Summary
Primary ovarian insufficiency (POI) is the condition of intermittent or permanent gonadal insufficiency that occurs in women before the age of 40. We describe three cases of POI referred to the outpatient endocrinology clinic of a university hospital. The three patients met diagnostic criteria for POI and were managed by specific approaches tailored to individualized goals. In the first case, the main concern was fertility and the reproductive prognosis. The second patient was a carrier of a common genetic cause of POI: premutation of the FMR1 gene. The third case was a patient diagnosed with a POI and established osteoporosis, a common complication of estrogen deprivation. This study reports the treatment and follow-up of these cases, with an emphasis on relevant aspects of individualized management, alongside a brief literature review.
Learning points
-
A diagnosis of POI should be considered in patients presenting with amenorrhea or irregular menses and high serum follicle-stimulating hormone (FSH) levels before age 40 years.
-
Patients with POI without an established cause, especially in familial cases, should be tested for FMR1 mutations.
-
Estrogen/progestin replacement therapy is indicated since diagnosis until at least the estimated age of menopause, and is the cornerstone for maintaining the good health of breast and urogenital tract and for primary or secondary osteoporosis prevention in POI.
-
Fertility should be managed through an individualized approach based on patient possibilities, such as egg or embryo donation and ovarian cryopreservation; pregnancy can occur spontaneously in a minority of cases.
-
Women with POI should be carefully monitored for cardiovascular risk factors.

Summary
A previously healthy 32-year-old woman developed cyclical mood swings after being prescribed cabergoline for a pituitary microprolactinoma. These mood swings persisted for over 2 years, at which point she developed an acute manic episode with psychotic features and was admitted to a psychiatry unit. Cabergoline was discontinued and replaced with aripiprazole 10 mg/day. Her manic episode quickly resolved, and she was discharged within 6 days of admission. The aripiprazole suppressed her prolactin levels for over 18 months of follow-up, even after the dose was lowered to 2 mg/day. There was no significant change in tumor size over 15 months, treatment was well tolerated. However, after 9 months of taking 2 mg aripiprazole, she developed brief manic symptoms, and the dose was returned to 10 mg daily, with good effect.
Learning points
-
Dopamine agonists such as cabergoline, which are a standard treatment for microprolactinomas, can have serious adverse effects such as psychosis or valvular heart disease.
-
Aripiprazole is a well-tolerated atypical antipsychotic that, unlike other antipsychotics, is a partial dopamine agonist capable of suppressing prolactin levels.
-
Adjunctive, low-dose aripiprazole has been utilized to reverse risperidone-induced hyperprolactinemia.
-
This case report demonstrates how aripiprazole monotherapy, in doses ranging from 2 to 10 mg/day, was effective in suppressing prolactin in a woman with a microprolactinoma who developed psychiatric side effects from cabergoline.
