RESUMEN
Introducción:
La terapia de elección de los prolactinomas son los agonistas dopaminérgicos, cuyo principal exponente es la bromocriptina, sin embargo, hay pacientes que no responden o presentan severos efectos secundarios (resistentes o intolerantes a bromocriptina, respectivamente). El objetivo en este estudio fue valorar la respuesta al uso de cabergolina en pacientes con prolactinomas, intolerantes o resistentes a bromocriptina Material ymétodos:
Se estudiaron 27 pacientes (25 mujeres y dos varones) en quienes se realizó determinación basal de prolactina y cada mes hasta completar tres meses, registrando los datos asociados a hiperprolactinemia y los efectos secundarios. La dosis inicial fue de 0.25 mg los lunes y jueves durante la primera semana, y 0.5 mg a partir de la segunda. El análisis estadístico incluyó la prueba de Shapiro-Wilk, Kruskal-Wallis y Anova.Resultados:
22 pacientes presentaron microadenomas y cinco macroadenomas. En los intolerantes (n = 11) el valor inicial de prolactina de 61.45 ± 19.82 disminuyó al tercer mes a 4.94 ± 1.79 (p < 0.024). En los resistentes (n = 16), el valor basal fue 119.53 ± 11.52; 15 pacientes redujeron significativamente a 12.95 ± 3.66 (p < 0.005) al tercer mes de tratamiento. En ambos, los signos atribuibles a la hiperprolactinemia mejoraron significativamente, con poca incidencia de efectos secundarios.Conclusiones:
La cabergolina es útil en la mayoría de los pacientes considerados intolerantes o resistentes a la bromocriptina.ABSTRACT
BACKGROUND:
Dopaminergic agonists are the treatment of choice for prolactinomas with bromocriptine (BCE) being the primary agent used. There is a group of patients who are not responders to such therapy or have severe side effects (resistant or intolerant to BCE, respectively). We undertook this study to evaluate the response to the administration of cabergoline (CBG) in patients intolerant or resistant to BCE.METHODS:
Twenty seven patients (25 females and 2 males) were recruited with prolactin-pituitary tumors, obtaining basal serum prolactin (PRL) samples and again each month up to 3 months. We recorded signs associated with hyperprolactinemia and secondary effects of CBG. The initial dose was 0.25 mg twice weekly during the first week, with an increase to 0.5 mg twice weekly from the second week until the conclusion of the study. Statistical analysis included Shapiro-Wilk, Kruskal-Wallis and ANOVA tests.RESULTS:
Twenty two patients had microadenomas and five had macroadenomas. In the intolerant group (n= 11), the initial PRL value (61.45 +/- 19.82) decreased by the third month to 4.94 +/- 1.79 (p<0.024). In the resistant group (n= 16), basal PRL values were 119.53 +/- 11.52. In 15 of these patients, the PRL value significantly decreased to 12.95 +/- 3.66 ng/ml (p<0.005) by the third month of treatment. In both groups the signs related to hyperprolactinemia significantly improved, with a low incidence of secondary effects due to CBG.CONCLUSIONS:
CBG is useful in most patients considered as intolerant or resistant to BCE.Palavras-chave
