ABSTRACT
Objetivos: Estimar la frecuencia de complicaciones maternofetales en mujeres que se embarazaron durante el tratamiento con cabergolina (CAB). Estimar la frecuencia de patología detectada posnacimiento en los niños producto de dichos embarazos. Material y métodos: Estudio retrospectivo y multicéntrico de 86 embarazos en 78 mujeres con hiperprolactinemia idiopática (7) o tumoral (44 micro y 27 macro), en tratamiento con CAB en el momento de la concepción. Edad: 20 a 45 años; PRL inicial: 30 a 1429 ng/ml; duración del tratamiento previo al embarazo 1 a 120 meses; dosis: 0.125 a 4 mg/semana. El rango de exposición embriofetal a la CAB fue de 3 a 27 semanas, el 96.39% de las pacientes la recibió durante el primer trimestre y el 3.61% hasta el segundo. Resultados: No hubo complicaciones mayores durante el embarazo. Se registraron 7 abortos espontáneos (8.1%) y 75 partos, de los cuales 49 fueron vaginales y 26 cesáreas. Se registraron 69 recién nacidos, 63 fueron a término y 6 pretérmino (8.8%), ninguno bajo peso para la edad gestacional. En 3 (5.2%) recién nacidos se observó: 1 malformación mayor (Síndrome de Down) y 2 menores (hernia umbilical e inguinal). Se obtuvo seguimiento de 42 recién nacidos; se diagnosticó epilepsia refractaria en uno y un trastorno generalizado del desarrollo en otro. No se halló una mayor frecuencia de complicaciones en los embarazos ni en los recién nacidos expuestos a CAB que en la población normal. Sería necesario mayor número de pacientes para concluir sobre la seguridad de CAB durante el embarazo.
Objectives: To assess the rate of any potential adverse effects on pregnancy and embryo-fetal development in women who became pregnant under treatment with cabergoline (CAB). To follow up medical data of children who were born from mothers exposed to Cab in early weeks of gestation. Material and methods: Observational, retrospective and multicenter study on 86 pregnancies in 78 women with idiopathic or tumoral hyperprolactinemia. All patients were under Cab at conception. The average age was 29 (range: 20-45). Pituitary images at diagnosis showed 44 microadenomas, 27 macroadenomas and 7 were normal. Serum PRL at baseline was between 30 and 1429 ng/ml. Duration of therapy before pregnancy ranged from 1 to 120 months. Maternal and fetal exposure to cabergoline and doses ranged from 0.125 to 4 mg/week. The mean serum PRL level under which patients achieved pregnancy was 17 ng/ml. Fetal exposure ranged from 3 to 27 weeks; 96.39% of patients received CAB during the first trimester of pregnancy and 3.61% until the second one. Results: No significant complications during pregnancy were found. Seven women (8.1%) had spontaneous abortions. Term deliveries were recorded in 63/69, preterm in six (8.8%), none of them with low weight for gestational age. Neonatal abnormalities were observed in 3 (5.2%): 1 major (Down syndrome) and 2 minor malformations (umbilical and inguinal hernia). Two out of 42, developed abnormalities during the follow- up, one of them was a refractory epilepsy during the second month of life, the other presented a Pervasive Developmental Disorder diagnosed in the third year of life. Conclusion: No significantly higher frequency of complications was found in pregnancies and/or offspring exposed to CAB than in normal population. Larger series of patients are needed to asses the safety.

Although cabergoline is effective in the treatment of micro- and macro-prolactinoma, little is known about its efficacy in the treatment of invasive giant prolactinoma. We investigated the efficacy and safety of cabergoline in 10 male patients with invasive giant prolactinoma. Before treatment, mean serum prolactin level was 11,426 ng/mL (range, 1,450-33,200 ng/mL) and mean maximum tumor diameter was 51 mm (range, 40-77 mm). Three months after initiation of cabergoline treatment, serum prolactin concentrations decreased more than 97% in 9 patients; at last follow-up (mean treatment duration, 19 months), the mean decrease in serum prolactin concentrations was 98%, with 5 patients having normal serum prolactin levels. At first MRI follow-up (3-12 months after initiation of cabergoline), the mean reduction in tumor size was 85+/-4% (range, 57-98%). Cabergoline treatment for more than 12 months caused a greater reduction in tumor size compared to the treatment for less than 12 months (97+/-1% vs. 78+/-7%, P<0.05). These findings indicate that cabergoline treatment led to a significant and rapid reduction in serum prolactin concentrations and tumor size in patients with giant prolactinoma. Therefore, cabergoline represents an effective and well-tolerated treatment for invasive giant prolactinoma.
