Adenoma hipofisário (prolactinoma) proveniente da disfunção hormonal da prolactina: revisão de literatura / Pituitary adenoma (prolactinoma) from prolactin hormonal dysfunction: literature review

Os adenomas hipofisários são, geralmente, tumores benignos com características de hipersecreção ou hipersecreção hormonal, diagnosticados conforme o crescimento tumoral, síndromes de hiperprodução, deficiência da secreção dos hormônios, alterações visuais e cefaleias. A hiperprolactinemia é a produção excessiva de prolactina (PRL), apresentando níveis elevados de prolactina sérica, o que resulta no aparecimento de adenomas lactotróficos (prolactinomas), predominante em mulheres com idade fértil. O prolactinoma é um adenoma hipofisário secretor de prolactina, classificado como adenoma hipofisário microadenoma, em mulheres, e macroadenoma, em homens. Nas mulheres, o prolactinoma apresenta indícios como galactorreia, amenorreia, disfunção sexual e infertilidade. Em homens, a sintomatologia pauta-se em ganho de peso, disfunção erétil e infertilidade. Os exames laboratoriais, como dosagem de prolactina sérica, e os exames de imagem, principalmente a ressonância magnética (RM), são importantes para confirmar o diagnóstico e a escolha da terapêutica ideal. O tratamento medicamentoso inicial dá-se por drogas agonistas dopaminérgicos (AD), sendo padrão-ouro a cabergolina (CAB), em razão da eficácia e dos efeitos colaterais reduzidos. Quando agonistas dopaminérgicos não surtem efeitos, indica-se submissão a tratamento cirúrgico. Em casos de tumores agressivos ou prolactinomas malignos, indica-se radioterapia. Sendo assim, este artigo corresponde a uma revisão bibliográfica que visa relacionar o adenoma hipofisário (prolactinoma) com a produção excessiva de prolactina (PRL).

Pituitary adenomas are generally benign tumors with characteristics of hypersecretion or hormonal hypersecretion, diagnosed according to tumor growth, hyperproduction syndromes, deficiency in hormone secretion, visual changes and headaches. Hyperprolactinemia is the excessive production of prolactin (PRL), with high levels of serum prolactin, resulting in the appearance of lactotrophic adenomas (prolactinomas), predominant in women of childbearing age. Prolactinoma is a prolactin-secreting pituitary adenoma, classified as pituitary adenoma microadenoma in women and macroadenoma in men. In women, prolactinoma shows signs such as galactorrhea, amenorrhea, sexual dysfunction and infertility. In men, the symptoms are based on weight gain, erectile dysfunction and infertility. Laboratory tests, such as serum prolactin levels, and imaging tests, especially magnetic resonance imaging (MRI), are important to confirm the diagnosis and choose the ideal therapy. The initial drug treatment is done by dopaminergic agonist drugs (AD), with cabergoline (CAB) being the gold standard, due to the reduced efficacy and side effects. When dopaminergic agonists have no effect, submission to surgical treatment is indicated. In cases of aggressive tumors or malignant prolactinomas, radiotherapy is indicated. Thus, this article corresponds to a bibliographic review that aims to relate pituitary adenoma (prolactinoma) with excessive prolactin production (PRL).

Establishment and comparison of two methods to produce a rat model of mammary gland hyperplasia with hyperprolactinemia

Abstract This study aimed to establish and compare models of mammary gland hyperplasia (MGH) with hyperprolactinemia (HPRL) using two different methods. The models provide information on the relationship between mammary gland hyperplasia and associated hormones. Model A was constructed using intramuscular injections of estradiol benzoate injection (EBI), followed by progesterone (P), and then metoclopramide dihydrochloride (MDI). Model B was designed by administering MDI, follow by EBI, and then P intramuscularly. Model B showed higher MGH progression compared with model A. Notably, increase in estradiol (E2) was negatively correlated with prolactin (PRL) secretion. However, PRL levels in model B were significantly higher compared with the levels in model A. Estrogen (ER), prolactin receptor (PRLR), and progesterone receptor (PR) mRNA and protein expression levels in model B rats were positively correlated with changes in the corresponding hormone levels. However, E2, P, and PRL levels in model A showed no direct relationship with levels of the mRNAs of related hormones and protein expression levels. Our results suggest that model B is an appropriate model of MGH with HPRL that can be used to perform further studies about the interactions of the E2, P, and PRL hormones in this disorder.

Hiperprolactinemia e infertilidad / Hyperprolactinemia and infertility

La prolactina es una hormona hipofisiaria implicada en diversas funciones tales como reproductivas, lactancia y metabólicas. El hallazgo de hiperprolactinemia es frecuente en mujeres que consultan por infertilidad, oscilando entre el 15 y el 20%. Sus manifestaciones clínicas incluyen trastornos del ciclo, galactorrea, infertilidad y osteoporosis. Cuando hay tumores que superan 1 cm de diámetro pueden asociarse a alteraciones visuales. Aunque la hiperprolactinemia puede ser producida por el embarazo, el consumo de algunos fármacos, los trastornos tiroideos, las alteraciones hepáticas y renales, su causa más frecuente es la presencia de adenomas hipofisiarios productores de prolactina. Pueden ser microadenomas cuando su tamaño es menor de 10 mm y que representan el 90% o macroadenomas cuando son de mayor tamaño. La prolactina se encuentra bajo un estrecho control de su secreción a través de un sistema de retroalimentación de asa corta que hace que se libere dopamina que frena su producción. También se han descrito péptidos liberados de prolactina entre los que se encuentra la TRH. El exceso en su producción inhibe directamente la pulsatilidad de la GnRH y disminución en los pulsos de LH. Este cambio conduce a ciclos anovulatorios. Para su manejo se encuentran aprobados en Colombia fármacos agonistas de la dopamina como bromocriptina y cabergolina, siendo este último más efectivo. El manejo con cirugía transesfenoidal se reserva para aquellos casos en los que el tratamiento farmacológico ha fallado.

Prolactin is an hypophyseal hormone implicated in various functions such as reproductive, lactation and metabolic. Finding hyperprolactinemia is frequent in women consulting for infertility, ranging between 15 and 20%. Its clinical manifestations include menstrual cycle irregularities, galactorrhea, infertility and osteoporosis. When tumors greater than 1 cm in diameter are present visual disturbances may appear. Although hyperprolactinemia may be produced by pregnancy, certain medications, thyroid disfunction, hepatic or renal disfunction, the most frequent cause is the presence of prolactin secreting adenomas. They can be micro adenomas when their diameter is less than 10 mm, representing 90% or macro adenomas when their size is greater. Prolactin secretion is under a close control through a short loop feedback system, that makes dopamine to be secreted which lowers its production. Releasing peptides have been described, including TRH. Excess in its production directly inhibits GnRH pulsatility lowering LH pulses. This change conducts to anovulatory cicles, For its treatment in Colombia dopamine agonists have been approved, including bromocriptine and cabergoline, the last one being mor effective. Surgical management with transesphenoidal approach is reserved for those cases in which pharmacological treatment has failed.

Comparative assessment of effect of malt with different bud length on prolactin in hyperprolactinemia rat

Malt is the mature fruit of Hordeum vulgare L. after germination and drying and has been applied for treatment female abnormal galactorrhea. Previous studies have showed total alkaloids in malt have anti-HPRL effect. However, total alkaloids of malt change with the growth cycle, and the specified levels of total alkaloids in different bud length of malt have not been decided. To determine the definitive level of total alkaloids in different buds of malt and the most suitable bud length for clinical application by comparing effects on hyperprolactinemia rat. During the budding of malt, the content of total alkaloids first increased and then decreased, and it peaked at a bud length of 0.75 cm. Treated the HPRL model rats with different buds of malt, the PRL level was decreased, the number of PRLpositive cells and the mRNA expression level in the pituitary were significantly declined, and the number of dopamine D1 and D2 receptors in the hypothalamus was increased. The above changes were most significant in 0.75 cm bud. These results suggest that in terms of the content of effective substance and the effects on HPRL model rats, a malt bud length of 0.75 cm is optimal for clinical application.

Hyperprolactinemia associated with psychiatric disorders / Hiperprolactinemia asociada con trastornos psiquiátricos

Abstract Hyperprolactinemia may be associated with psychiatric disorders in the context of two scenarios: antipsychotic-induced hyperprolactinemia and psychiatric disorders arising from the medical treatment of hyperprolactinemia. Both situations are particularly common in psychiatric and endocrine clinical practice, albeit generally underestimated or unrecognized. The aim of this article is to provide tools for the diagnosis and treatment of hyperprolactinemia associated with psychiatric disorders to raise awareness, especially among psychiatrists and endocrinologists, so that these professionals can jointly focus on the appropriate management of this clinical entity.

Resumen La hiperprolactinemia puede asociarse con trastornos psiquiátricos en el contexto de dos escenarios: la hiperprolactinemia inducida por antipsicóticos y trastornos psiquiátricos surgidos por el tratamiento médico de la hiperprolactinemia. Ambas situaciones son particularmente comunes en la práctica clínica psiquiátrica y endocrinológica, aunque generalmente subestimadas o inadvertidas. El objetivo de este artículo es proporcionar herramientas de diagnóstico y tratamiento de la hiperprolactinemia asociada a trastornos psiquiátricos, para concientizar particularmente a psiquiatras y endocrinólogos a enfocar en conjunto el manejo apropiado de esta entidad.

Caracterización clínico-etiológica y bioquímica de pacientes con ginecomastia / Clinical- etiological and biochemical characterization of patients with gunecomastia

RESUMEN Introducción: La ginecomastia define el aumento benigno del tamaño de la glándula mamaria en el hombre. Objetivo: Determinar las características clínicas, etiológicas y bioquímicas de los pacientes con diagnóstico de ginecomastia atendidos en el servicio de Cirugía General. Método: Se realizó un estudio descriptivo de corte transversal en una muestra de 108 pacientes, mayores de 18 años, atendidos en el servicio de Cirugía General con diagnóstico de ginecomastia. El estudio se llevó a cabo en los Hospitales Mariano Pérez Balí y Celia Sánchez Manduley, entre septiembre 2015 y marzo 2017. Se determinó edad, características clínicas, etiología y perfil bioquímico de estos pacientes. Resultados: La edad media fue de 27,63 años siendo la afectación estética el principal motivo de consulta. Predominó la ginecomastia bilateral, el sobrepeso/obesidad, el grado IIa de la enfermedad, la etiología idiopática y el antecedente de ginecomastia puberal. La presencia de galactorrea, hiperprolactinemia, hipoandrogenismo e hiperestrogenemia fue mínima. Conclusiones: La ginecomastia bilateral de causa idiopática, en pacientes con sobrepeso/obesidad y niveles normales de hormonas hipofisarias y gonadales es la forma de presentación más frecuente de esta afección(AU)

ABSTRACT Introduction: Gynecomastia defines the benign increase of the mammary gland size in men. Objective: To determine the clinical, etiological and biochemical characteristics of patients diagnosed with gynecomastia attended at the General Surgery service. Methods: A descriptive cross-sectional study was conducted in a sample of 108 patients over the age of 18 years, attended at the service of General Surgery with a diagnosis of gynecomastia. The study was carried out in ´´Mariano Perez Bali´´ and ´´Celia Sánchez Manduley´´ Hospitals from September 2015 to March 2017. The age, clinical characteristics, etiology, and biochemical profile of these patients were determined. Results: The mean age was 27.63 years and the aesthetic affectations were the main reason for consultation. There was a predominance of bilateral gynecomastia, overweight/obesity, grade IIa of the disease, idiopathic etiology and the history of pubertal gynecomastia. The presence of hyperprolactinemia, galactorrhea, hypoandrogenism and hyperstrogenism was minimal. Conclusions: Bilateral gynecomastia of idiopathic cause, in patients with overweight/obesity and normal levels of gonadal and pituitary hormones is the most common presentation of this condition(AU)

Body self-image disturbances in women with prolactinoma

Objective: To evaluate body dissatisfaction and distorted body self-image in women with prolactinoma. Methods: Body dissatisfaction and distorted body self-image were evaluated in 80 women with prolactinoma. All patients were in menacme, 34% had normal body mass index (BMI), and 66% were overweight. Most patients (56.2%) had normal prolactin (PRL) levels and no hyperprolactinemia symptoms (52.5%). The Body Shape Questionnaire (BSQ) was used to assess the patients' dissatisfaction with and concern about their physical form, and the Stunkard Figure Rating Scale (FRS) was used to assess body dissatisfaction and distorted body self-image. The patients were divided according to PRL level (normal vs. elevated) and the presence or absence of prolactinoma symptoms. Results: The normal and elevated PRL groups had similar incidences of body dissatisfaction and distorted body self-image. However, symptomatic patients reported a higher incidence of dissatisfaction than asymptomatic patients. Distorted body self-image was less common among symptomatic patients. Conclusion: Symptomatic patients showed higher body dissatisfaction, but lower body self-image distortion. The presence of symptoms may have been responsible for increased body awareness. The perception of body shape could have triggered feelings of dissatisfaction compared to an ideal lean body. Therefore, a distorted body self-image might not necessarily result in body dissatisfaction in women with prolactinomas.

Resolution of headache after reduction of prolactin levels in hyperprolactinemic patients / Resolução de cefaleia após redução dos níveis de prolactina em pacientes com hiperprolactinemia

Abstract Prolactin (PRL) secreting adenomas are associated with high incidence of headache. The role of hyperprolactinemia in the headache context is not clear, nor is the effect of its treatment on headache. Methods: The present longitudinal study evaluated hyperprolactinemic patients (69), in terms of presence and characteristics of headache before and after hyperprolactinemia treatment. Results: Headache was reported by 45 (65.2%) patients, independent of the etiology of hyperprolactinemia. The migraine phenotype was the most prevalent (66.6%). Medications used in the treatment of headache not changed during the study. The first line of treatment of hyperprolactinemia was dopaminergic agonists. In the last reevaluation, PRL level under treatment was within the reference range in 54.7% of the cases, and it was observed complete or partial resolution of the headache in 75% of the cases. The median PRL at this time in patients with complete headache resolution was 17 ng/mL, in those who reported partial recovery was 21 ng/mL, and in those in whom the headache did not change was 66 ng/mL, with a significant difference between the group with complete headache resolution vs. the group with unchanged headache (p=0.022). In the cases with complete headache resolution, the median fall on PRL levels was 89% and in those cases with partial headache resolution 86%, both significantly different (p<0.001) from the fall in the cases with an unchanged headache. Conclusion: Data allow us to conclude that, in this series, in the majority of cases the reduction in the level of PRL was followe3d by cessation or relief of the pain.

Resumo Os adenomas secretores de prolactina (PRL) estão associados à alta incidência de cefaleia. O papel da hiperprolactinemia no contexto da dor de cabeça não está claro, nem o efeito da redução dos níveis da PRL na cefaleia. Métodos: O presente estudo longitudinal avaliou pacientes hiperprolactinêmicos (69), quanto à presença e às características da cefaleia antes e após o tratamento da hiperprolactinemia. Resultados: Cefaleia foi relatada por 45 (65,2%) pacientes, independente da etiologia da hiperprolactinemia. O fenótipo de enxaqueca foi mais prevalente (66,6%). Os medicamentos usados ​​no tratamento da cefaleia não foram alterados durante o estudo. A primeira linha de tratamento da hiperprolactinemia foram os agonistas dopaminérgicos. Na última reavaliação, o nível de PRL sob tratamento estava dentro da faixa de referência em 54,7% dos casos, observando-se resolução completa ou parcial da cefaleia em 75% dos casos. A mediana de PRL neste momento em pacientes com resolução completa da cefaleia foi de 17 ng/mL, nos que relataram recuperação parcial foi de 21 ng/mL, e naqueles em que a cefaleia não se alterou foi de 66 ng/mL, com uma diferença significativa entre o grupo com resolução completa da cefaleia versus o grupo com cefaleia inalterada (p=0,022). Nos casos com resolução completa da cefaleia, a queda mediana nos níveis de PRL foi de 89% e nos casos com resolução parcial de cefaleia de 86%, ambos significativamente diferentes (p<0,001) da queda nos casos com cefaleia inalterada. Conclusão: Os dados permitem concluir que, nesta série, na maioria dos casos, a redução do nível de PRL foi seguida pela cessação ou alívio da dor.

Quiste de bolsa de Rathke e hiperprolactinemia, una causa infrecuente de amenorrea primaria / Rathke cleft cysts and hyperprolactinemia, an uncommon cause of primary amenorrhea

El quiste de la bolsa de Rathke es una lesión epitelial benigna de la región selar, formada a partir de remanentes embrionarios. La mayoría de los casos son asintomáticos, aunque pudiera presentarse con cefalea, disfunción hipofisaria y trastornos visuales, muy infrecuentemente como apoplejía hipofisaria. Se presenta el caso de una paciente que, habiendo presentado amenorrea primaria, se le realiza el diagnóstico de quiste de la bolsa de Rathke con hiperprolactinemia, logrando menarquia luego del tratamiento con cabergolina.

Rathke's cyst is a benign epithelial lesion of the sellar region, formed from embryonic remnants. Most cases are asymptomatic although it could present with headache, pituitary dysfunction and visual disorders, very infrequently as pituitary stroke. We present the case of a patient who, having presented primary amenorrhea, is diagnosed with Rathke's cyst with hyperprolactinemia, achieving menarche after treatment with cabergoline.

Tratamiento hormonal y sus complicaciones en el paciente con disforia de género / Hormonal treatment and complications in patients with gender dysphoria

RESUMEN Introducción: Las personas con disforia de género sienten incongruencia entre el sexo con el que nacen y aquel al que sienten pertenecer, por lo que necesitan adaptar su cuerpo a este último, y uno de los pilares en el logro de ese propósito es el empleo del tratamiento hormonal cruzado. Objetivo: Identificar los esquemas terapéuticos más empleados en la automedicación y en el manejo especializado, y sus complicaciones en pacientes con disforia de género. Métodos: Se revisaron 78 historias, de las cuales 76 correspondían a transexuales hombre-mujer, atendidos en el periodo 2012-2017 en la Consulta Nacional de Atención Integral a Personas Transgénero. Se recuperó información relacionada con los esquemas terapéuticos utilizados, tanto durante la automedicación como durante el manejo por el endocrinólogo, y las complicaciones. Para el análisis de los datos se obtuvieron distribuciones de frecuencia de las variables cualitativas, media y desviación estándar de las cuantitativas. Resultados: La frecuencia de pacientes que se autoadministraron hormonas antes de comenzar la atención especializada fue de 82,9 por ciento. El medicamento más utilizado en la automedicación fue la cipresta (acetato de ciproterona 2 mg/etinilestradiol 50 µg) en el 90,5 por ciento de los casos. De los tratamientos indicados por el endocrinólogo al inicio de la atención; al 50,0 por ciento se les administró cipresta más androcur (acetato de ciproterona 50 mg) de 1 a 2 tabletas de cada uno, mientras que al 39,5 por ciento estrógenos conjugados asociado a androcur, igualmente de 1 a 2 tabletas de cada uno de estos medicamentos. En cuanto a la frecuencia de complicaciones como consecuencia del tratamiento hormonal, el 40,7 por ciento de los casos tuvo en algún momento niveles elevados de prolactina, al 26,3 por ciento los niveles de triglicéridos se le elevaron luego de iniciada la terapia. Conclusiones: La mayoría de los pacientes acuden por primera vez automedicados. Los medicamentos más utilizados son la cipresta y el androcur. La complicación más frecuente como consecuencia del tratamiento es la hiperprolactinemia(AU)

ABSTRACT Introduction: Persons with gender dysphoria feel incongruity between the sex they are born with and the one they feel they belong to, therefore they need to adapt their body to the latter, and one of the pillars in achieving that purpose is the use of cross hormonal treatment. Objective: To identify the therapeutic schemes most used in self-medication and specialized management, and their complications in patients with gender dysphoria. Methods: Seventy eight medical records were reviewed. Seventy six of them corresponded to male-female transsexuals, assisted in the 2012-2017 period at the National Consultation of Comprehensive Care to Transgender Persons. The study team recovered information related to the therapeutic schemes used, both during self-medication and during the endocrinological management, as well as complications. Frequency distributions of the qualitative variables, mean and standard deviation of the quantitative variables were obtained for data analysis. Results: The frequency of patients who self-administered hormones before beginning specialized care was 82.9 percent. The most commonly medication used in self-medication was cypress (cyproterone acetate 2 mg / ethinylestradiol 50 µg) in 90.5 percent of cases. Out of the treatments indicated by the endocrinologist at the beginning of the care; 50.0 percent were given cypress plus androcur (50 mg cyproterone acetate) of 1 to 2 tablets each, while 39.5 percent conjugated estrogens associated with androcur, also 1 to 2 tablets of each of these medications. Regarding the frequency of complications as a result of hormonal treatment, 40.7 percent of the cases had elevated prolactin levels at some time, and triglyceride levels increased to 26.3 percent after the start of therapy. Conclusions: Most patients who come for the first time, are self-medicated. The most used medications are cipresta and androcur. The most frequent complication is hyperprolactinemia as a consequence of treatment(AU)

Hiperprolactinemia, amenorrea secundaria y trastornos del ciclo menstrual / Hyperprolactinemia, secondary amenhorrea and menstrual cycle disorders

La hiperprolactinemia es la enfermedad endocrina más frecuente del sistema hipotálamohipófisis-ovario; es una entidad de mucho interés por sus manifestaciones clínicas y diversidad de ellas principalmente los trastornos del ciclo e infertilidad secundaria, como por sus efectos a largo plazo. Es necesario que estas pacientes tengan una evaluación sistemática basada en una historia clínica dirigida y complementada con exámenes de laboratorio, en donde la determinación de PRL sea un requisito indispensable. Es importante descartar causas secundarias como el uso de medicamentos, adicciones, estados de estrés y principalmente tumores funcionantes de hipófisis. Se debe evaluar la historia clínica y complementarla con exámenes de laboratorio para tomar una decisión adecuada de tratamiento.

Hyperprolactinemia is the most frequent endocrine disease of the hypothalamus pituitary ovary system, is an entity of great interest for its clinical diversity of manifestations, mainly menstrual cycle disorders and secondary infertility. It is necessary that these patients have a systematic evaluation based on a guided clinical history and supplemented with laboratory tests, where the determination of PRL is an indispensable requirement. It is important to rule out secondary causes such as the use of medications, stress and mainly functioning tumors of the pituitary gland. The clinical history should be evaluated, complemented with laboratory tests to make an adequate decision on their treatment.

Importancia de la anamnesis exhaustiva ante una ginecomastia unilateral inexplicada en un niño / Importance of the exhaustive anamnesis to an unexplained unilateral gynecomastia in a child

La ginecomastia es el crecimiento de la mama por un desequilibrio hormonal entre estrógenos y andrógenos. Un crecimiento importante y unilateral requiere descartar patologías subyacentes. Una causa poco frecuente es la traumática, que provoca aumento de tamaño por estimulación repetida. Se presenta el caso de un niño de 6 años con ginecomastia unilateral. Se destaca como único hallazgo en las pruebas complementarias hiperprolactinemia. Rehistoriando, se detecta una continua autoestimulación mamaria manual y oral a través de mordiscos de meses de evolución. Tras el cese del estímulo, se observa la involución de la mama y la normalización de los niveles de prolactina séricos.

Gynecomastia consists of breast enlargement due to a hormonal imbalance between estrogens and androgens. Unilateral and important breast growth requires ruling underlying pathologic disorders out. Mechanical cause is uncommon, causing enlargement by repeated stimulation. We report a 6-year-old boy with unilateral gynecomastia. Hyperprolactinemia is the only abnormal finding at laboratory tests. After repeated inquiries, a continuous breast selfstimulation is detected. Its relation with gynecomastia is verified because prolactin normalizes and breast regressed in further revisions, after stopping stimulus.

Primary amenorrhea associated with hyperprolactinemia in polyglandular autoimmune syndrome type II: A case report / Amenorreia primária associada com hiperprolactinemia em síndrome poliglandular autoimune tipo 2: relato de caso

Abstract Polyglandular autoimmune syndrome type II (PGA-II) is a rare immunoendocrinopathy syndrome characterized by the occurrence of autoimmune Addison disease along with diabetes mellitus type 1 and/or autoimmune thyroid disease. Here, we report the case of a 23-year-old female with PGA-II who was followed up at the dermatology and endocrinology clinics of the Universidade Federal do Triângulo Mineiro, located in the state of Minas Gerais, Brazil. First, the patient presented diffuse skin hyperpigmentation, vitiligo; and in sequence, due to vomiting, appetite and weight loss, hypoglycemia, amenorrhea, and galactorrhea, the patient was then diagnosed with PGA-II. The patient also presented intense hyperprolactinemia due to primary hypothyroidism. The late diagnosis of PGA-II is frequent because the disorder is uncommon and has non-specific clinical manifestations. This report emphasizes the significance of a timely diagnosis and appropriate treatment to reduce morbidity and mortality associated with these diseases, especially Addison disease. The present study reports a rare case of a patient with PGA-II with primary amenorrhea associated with hyperprolactinemia.

Resumo A síndrome poliglandular autoimune tipo 2 (SPGA-2) é uma síndrome de imunoendocrinopatia rara caracterizada por doença de Addison autoimune associada à diabetes mellitus tipo 1 e/ou doenças tireoidianas autoimunes. Relatamos aqui o caso de uma paciente de 23 anos de idade com SPGA-2 que foi acompanhada nos ambulatórios de dermatologia e endocrinologia da Universidade Federal do Triângulo Mineiro, localizada no estado de Minas Gerais, Brasil. Primeiramente, a paciente apresentou hiperpigmentação cutânea difusa e vitiligo; posteriormente, por apresentar vômitos, hiporexia, perda ponderal, hipoglicemia, amenorreia e galactorreia, foi diagnosticada com SPGA-2. A paciente apresentou também intensa hiperprolactinemia secundária apenas ao hipotireoidismo primário. É comum o diagnóstico tardio da SPGA-2, pois a doença é rara e apresenta manifestações clínicas inespecíficas. Este relato de caso enfatiza a importância do diagnóstico e tratamento precoces como objetivo de reduzir a morbimortalidade associada a essas doenças, especialmente à doença de Addison. O presente estudo descreve um caso raro de uma paciente com SPGA-2 com amenorreia primária associada a hiperprolactinemia.

Controversial issues in the management of hyperprolactinemia and prolactinomas - An overview by the Neuroendocrinology Department of the Brazilian Society of Endocrinology and Metabolism

ABSTRACT Prolactinomas are the most common pituitary adenomas (approximately 40% of cases), and they represent an important cause of hypogonadism and infertility in both sexes. The magnitude of prolactin (PRL) elevation can be useful in determining the etiology of hyperprolactinemia. Indeed, PRL levels > 250 ng/mL are highly suggestive of the presence of a prolactinoma. In contrast, most patients with stalk dysfunction, drug-induced hyperprolactinemia or systemic diseases present with PRL levels < 100 ng/mL. However, exceptions to these rules are not rare. On the other hand, among patients with macroprolactinomas (MACs), artificially low PRL levels may result from the so-called "hook effect". Patients harboring cystic MACs may also present with a mild PRL elevation. The screening for macroprolactin is mostly indicated for asymptomatic patients and those with apparent idiopathic hyperprolactinemia. Dopamine agonists (DAs) are the treatment of choice for prolactinomas, particularly cabergoline, which is more effective and better tolerated than bromocriptine. After 2 years of successful treatment, DA withdrawal should be considered in all cases of microprolactinomas and in selected cases of MACs. In this publication, the goal of the Neuroendocrinology Department of the Brazilian Society of Endocrinology and Metabolism (SBEM) is to provide a review of the diagnosis and treatment of hyperprolactinemia and prolactinomas, emphasizing controversial issues regarding these topics. This review is based on data published in the literature and the authors' experience.

Apoplejía hipofisaria, presentación de dos casos clínicos y revisión del tema / Pituitary apoplexy, presentation of two clinical cases and review of the subject

Antecedentes: la apoplejía hipofisaria es un síndrome clínico agudo, potencialmente fatal, que acontece como complicación de un adenoma hipofisario; presenta una complejidad diagnóstica, y puede imitar numerosos procesos intracraneales. Objetivo: realizar la revisión bibliográfica del tema, y describir dos casos clínicos, dada la poca frecuencia de presentación de la enfermedad y su complejidad diagnóstica. Desarrollo: caso 1, paciente masculino, de 52 años con antecedentes patológicos de hipertensión arterial y macroadenoma hipofisario no funcionante. Durante su seguimiento por Neurocirugía se detectó hiperprolactinemia, por lo que se inició tratamiento con bromocriptina a dosis progresiva, lo cual desencadenó cuadro agudo no definido. Tres meses después presentó nuevo cuadro agudo, que se diagnosticó como apoplejía hipofisaria; caso 2, paciente masculino, de 49 años, con antecedente de hipertensión arterial con tratamiento irregular. Fue ingresado en servicio de terapia intermedia con diagnóstico presuntivo de meningoencefalitis, y por estudios complementarios se llega al diagnóstico de apoplejía hipofisaria. Ambos casos llevaron tratamiento quirúrgico, con evolución favorable. Conclusiones: la apoplejía hipofisaria es una enfermedad que se presenta con poca frecuencia, por lo tanto, es importante la sospecha diagnóstica para una temprana identificación y tratamiento de la enfermedad(AU)

Background: pituitary apoplexy is an acute clinical syndrome, potentially fatal, that occurs as a complication of a pituitary adenoma. It presents a diagnostic complexity, and it can mimic numerous intracranial processes. Objective: to carry out the bibliographic review of the subject, and to describe two clinical cases given the infrequency of presentation of the disease and its diagnostic complexity. Development: case 1, male patient, 52 years old with pathological history of arterial hypertension and non-functioning pituitary macroadenoma. During follow-up by Neurosurgery, hyperprolactinemia was detected, so treatment with bromocriptine was started with a progressive dose, which triggered undefined acute symptoms. Three months later he presented new acute symptoms, which was diagnosed as pituitary apoplexy. Case 2, male patient, 49 years old, with a history of arterial hypertension under irregular treatment. He was admitted in the intermediate therapy service with a presumptive diagnosis of meningoencephalitis, and by complementary studies the diagnosis of pituitary apoplexy was reached. Both cases led to surgical treatment, with favorable evolution. Conclusions: pituitary apoplexy is a disease that occurs infrequently, therefore, diagnostic suspicion is important for early identification and treatment of the disease(AU)

Investigación electrónica del tratamiento de la hiperprolactinemia en Brasil: endocrinólogos contra ginecólogos / Electronic survey of management of hyperprolactinemia in Brazil: Endocrinologists versus gynecologists

Hyperprolactinemia is a frequent condition in clinical practice, responsible for 20-25% of secondary amenorrhea cases. We performed an electronic survey among members of the Brazilian Society of Metabolism and Endocrinology (SBEM) and the Brazilian Federation of Association of Gynecology and Obstetrics (FEBRASGO) to assess diagnostic and therapeutic preferences for management of hyperprolactinemia. Electronic addresses of SBEM and FEBRASGO members were obtained from the directories of these societies, and these members were invited, through electronic messages (e-mail), to answer an online questionnaire that included 10 questions about the treatment of micro and macropro-lactinomas, maximum dose of dopamine agonist, how to exclude primary hypothyroidism and macroprolactinemia, hyperprolactinemia and pregnancy. We received responses to the questionnaire by e-mail from 521 SBEM members and 233 FEBRASGO members. The results of this survey demonstrate that there are many area of agreement between SBEM and FEBRASGO members and most of their responses follow the latest Endocrine Society Guideline. Relative to a survey performed several years ago, our findings show that SBEM members have incorporated some of latest recommendations in this field. The principal issues of concern for both groups are duration of dopamine agonist treatment for patients with microprolactinoma and dopamine agonist withdrawal during pregnancy.

La hiperprolactinemia es una alteración frecuente, siendo responsable del 20 al 25% de los casos de amenorrea secundaria. Se realizó una investigación electrónica entre los miembros de la Sociedad Brasileña de Endocrinología y Metabología (SBEM) y de la Federación Brasileña de Ginecología y Obstetricia (FEBRASGO) para evaluar sus preferencias en el diagnóstico y el tratamiento de la hiperprolactinemia. Las direcciones electrónicas de miembros SBEM y de FEBRASGO se obtuvieron a partir de los directorios de esas sociedades. Se invitó a estos miembros a responder un cuestionario que incluía 10 cuestiones sobre el tratamiento de los micro y macroprolactinomas, dosis máxima del agonista dopaminérgico, hiperprolactinemia e hipotiroidismo primario, macroprolactinemia, prolactinoma y embarazo. Hemos recibido respuestas de 521 miembros de la SBEM y de 233 miembros FEBRASGO. Los resultados demuestran que hay bastantes áreas de concordancia entre los miembros de la SBEM y de la FEBRASGO y que la mayoría de las respuestas están de acuerdo con el último consenso de la Endocrine Society. En cuanto a una encuesta similar realizada hace años, nuestros resultados muestran que los socios de SBEM incorporaron algunas de las últimas recomendaciones propuestas en esa área. Los principales aspectos de interés en ambos grupos son la duración del tratamiento con el agonista dopaminérgico y la retirada del mismo durante el embarazo.

Hiperprolactinemia idiopática / Idiopathic hyperprolactinemia

La hiperprolactinemia es uno de los trastornos neuroendocrinológicos más frecuentes; la causa común de la hiperprolactinemia es la presencia de un adenoma hipofisario productor de prolactina o prolactinoma. El país cuenta con escasa referencia bibliográfica sobre la patología presentada, por lo que resulta importante realizar la exposición de este caso. Objetivo: documentar el abordaje de hiperprolactinemia en el país. Caso clínico: paciente femenina de 22 años, con antecedentes familiares de macroprolactinoma; se presenta con historia de amenorrea de 6 años y caída de cabello de 2 años de evolución; prurito intenso en ambas mamas con predominio en la areola derecha desde hace 1 año; alteraciones en los niveles de prolactina presentando valores de 33.5ng/mL y ultrasonografía abdominal ausente de anormalidades. Tratada con cabergolina, sin éxito evidente en el tratamiento. Conclusión: en pacientes con hiperprolactinemia, su abordaje debe hacerse de manera ordenada, integral, secuencial y detallada con el fin de descartar previo al tratamiento, situaciones que secundariamente elevan los valores de prolactina. Esto lo demuestra el caso expuesto donde se integran diferentes pruebas clínicas y laboratoriales para descartar la etiología de la hiperprolactinemia en el país...(AU)
