BACKGROUND: Hyperprolactinemia is the most common disturbance in pituitary gland secretion. Functional diversity of prolactin action is responsible for different initial clinical expressions of hyperprolactinemia.
PATIENTS AND METHODS: We investigated causes of hyperprolactinemia in 11 children and adolescents (6 females and 5 males), aged from 1.5 to 17.5 years. Children with primary hypothyroidism, iatrogenic hyperprolactinemia and adolescents with polycystic ovaries were excluded.
RESULTS: Four patients had short stature or growth deceleration, the same number were clinically obese, 2 adolescent girls had secondary amenorrhea, 1 girl had premature thelarche and gynecomastia, and hypogonadism was the indication for the endocrinologic examination of two adolescent boys. Delayed pubertal development was present in both sexes. Hyperprolactinemia was also found in the youngest girl with multiple ovarian cysts. A very high prolactin (PRL) level was documented in the PRL profile of all patients (mean 2,553.00 +/- 1,020.97 mU/l). MRI of the pituitary was indicated and revealed 4 microprolactinomas, one congenital hypophyseal cyst and one tumor of the hypothalamus. Dopamine agonist treatment was efficacious in almost all the patients.
CONCLUSION: Hyperprolactinemic children expressed a wide variety of initial clinical presentations. The most common were growth and puberty disorders and obesity. PRL determination should be included in investigation protocols of obese and short stature children.
