Progestinas y cáncer de mama en terapia de reemplazo hormonal: cómo actúan y qué alternativas son más seguras / Progestins and breast cancer in hormone replacement therapy: how do they work, and what alternatives are safer

En algunos estudios se ha asociado a la terapia de reemplazo hormonal (TRH) con estrógenos y progestinas a un mayor riesgo de cáncer de mama que la terapia con estrógenos solos. Sin embargo, dependiendo de su naturaleza algunas progestinas serían más seguras que otras. Se buscaron y analizaron artículos atingentes al tema en las bases de datos Google Scholar, PubMed, Science, SciELO y Cochrane, introduciendo los siguientes términos: terapia de reemplazo hormonal y cáncer de mama, progestinas y cáncer de mama, receptor de progesterona. Específicamente se ha asociado a las progestinas sintéticas acetato de medroxiprogesterona, noretisterona y levonorgestrel con un mayor riesgo de cáncer de mama, no así a la progesterona natural, a la progesterona oral micronizada ni a la didrogesterona. La progesterona natural, progesterona micronizada y didrogesterona serían más seguras en TRH para evitar el desarrollo de cáncer de mama, lo que estaría dado por la mayor especificidad en su acción.

In some studies, hormone replacement therapy (HRT) with estrogens and progestins has been associated with a higher risk of breast cancer than therapy with estrogens alone. However, depending on their nature, some progestins may be safer than others. This article analyzes the mode of action of progesterone in breast tissue and also the role of some progestins in the development of this pathology. Articles related to the subject were searched for and analyzed in Google Scholar, PubMed, Science, SciELO and Cochrane databases, introducing the following terms: hormone replacement therapy and breast cancer, progestins and breast cancer, progesterone receptor. Specifically, synthetic progestins medroxyprogesterone acetate, norethisterone, and levonorgestrel have been associated with an increased risk of breast cancer, but not natural progesterone, micronized oral progesterone, or dydrogesterone. Natural progesterone, micronized progesterone and dydrogesterone would be safer in HRT to prevent the development of breast cancer, which would be due to the greater specificity of their action.

Terapia hormonal de la menopausia en el año 2021 / Hormone therapy for menopause in 2021

Describe los planteamientos sobre el beneficio de la terapia de reemplazo hormonal en las mujeres en la menopausia y el riesgo de contraer cáncer de mama con el uso prolongado del mismo.

Terapia de reemplazo hormonal después del cáncer de mama: ¿sí, no o quizás? / Hormone replacement therapy after breast cancer: yes, no, or maybe?

Más de nueve millones de sobrevivientes de cáncer de mama en todo el mundo sufren un deterioro en la calidad de vida atribuible a los síntomas de la menopausia relacionados con el déficit de los estrógenos y con los efectos secundarios de la terapia contra el cáncer. La terapia de reemplazo hormonal (TRH) es muy eficaz para controlar estos síntomas en la población general y en las sobrevivientes de cáncer de mama. Sin embargo, la preocupación de la recurrencia del cáncer de mama como resultado del uso de TRH impide que muchos oncólogos utilicen este enfoque en el tratamiento de los síntomas menopáusicos. La evidencia de ensayos aleatorizados, estudios observacionales y meta-nálisis sobre el impacto del uso de TRH en la recurrencia y supervivencia del cáncer de mama sigue siendo controvertida.

More than nine million breast cancer survivors in everyone suffers a deterioration in the quality of life attributable to the symptoms of menopause related to the deficiency of the estrogens and with the side effects of anti-estrogen therapy Cancer. Hormone replacement therapy (HRT) is very effective in controlling these symptoms in the general population and in survivors of breast cancer. However, the concern of recurrence of breast cancer as a result of the use of HRT prevents many oncologists use this approach in the treatment of menopausal symptoms. Evidence from randomized trials, observational studies, and meta-analysis on the impact of the use of HRT on recurrence and Breast cancer survival remains controversial

Hematometra y hematocervix en paciente postmenopáusica: reporte de caso / Hematometry and hematocervix in postmenopausal patient: case repor

El hematometra es la retención de sangre en el útero y comúnmente se presenta en mujeres jóvenes con anomalías mullerianas pero puede aparecer también en mujeres postmenopausicas por causas secundarias como traumas, tumores, terapia de remplazo hormonal, estenosis cervical, entre otras. En esta presentación de caso interesante se describe una mujer postmenopáusica bajo terapia de remplazo hormonal. Dicha mujer inicia con hemorragia uterina anormal por lo que se le realiza ultrasonido evidenciando hematómetra y hematocervix. Como método diagnóstico y terapéutico de la hemorragia postmenopáusica se le realiza histerectomía abdominal en la cual la patología evidencia leiomiomatosis uterina con endometrio secretor

Hematometra is the retention of blood in the uterus and commonly occurs in young women with Mullerian abnormalities but can also appear in postmenopausal women due to secondary causes such as trauma, tumors, hormone replacement therapy, cervical stenosis, among others. In this presentation an interesting case is described a postmenopausal woman under hormone replacement therapy. She said woman began with abnormal uterine bleeding, so an ultrasound was performed showing hematometer and hematocervix. As a method diagnosis and treatment of postmenopausal hemorrhage, abdominal hysterectomy is performed in which the pathology shows uterine leiomyomatosis with secretory endometrium

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)

Terapia de reemplazo hormonal y enfermedad cardiovascular en el hombre adulto hipogonádico / Hormone replacement therapy and cardiovascular disease in the hypogonadal adult men

RESUMEN El diagnóstico de hipogonadismo requiere de la presencia de síntomas y signos sugestivos de deficiencia de testosterona asociado a la confirmación por estudios de laboratorio de valores de testosterona por debajo del valor normal. Se ha descrito un aumento en la prescripción de la terapia androgénica en el hipoandrogenismo asociado con la edad, y existe preocupación sobre los potenciales efectos adversos en especial a nivel cardiovascular relacionados con la misma. Los mecanismos fisiopatológicos propuestos en relación a los posibles efectos adversos de la testosterona sobre el sistema cardiovascular incluyen: aumento de la expresión de receptor para tromboxano A2 (TXA2), aumento de la expresión vascular en células endoteliales de la molécula de adhesión vascular 1 (VCAM1), estimulación de la eritropoyesis con el desarrollo de policitemia, como también aumento de la incidencia de síndrome apnea del sueño. Pero por otra parte, existe evidencia de que el hipogonadismo no tratado se asocia a aumento de enfermedad cardiovascular y mortalidad. Se sugiere considerar la administración de TRH en pacientes con hipogonadismo sintomático, tomando en cuenta los riesgos y beneficios asociados a la misma y con precaución en su indicación en los pacientes más frágiles y con alto riesgo cardiovascular.

ABSTRACT The diagnosis of hypogonadism requires of the presence of symptoms and signs suggestive of testosterone deficiency associated with confirmation by laboratory studies of testosterone below the normal value. It has been described an increase in the prescription of androgenic therapy in late onset hypogonadism (associated with aging) and there is concern of its potential adverse effects, especially on cardiovascular events. The proposed physiopathological mechanisms, related to the adverse effects of testosterone on the cardiovascular system include: increased expression of thromboxane A2 receptors (TXA2), increased expression of vascular cell adhesion molecule-1 (VCAM1), stimulation of erythropoiesis with the development of polycythemia, as well as an increase in the incidence of sleep apnea syndrome. On the other hand, evidence exists on the association of not treated hypogonadism with an increase in cardiovascular disease and mortality. It is suggested to consider the use of testosterone therapy in patients with symptomatic hypogonadism, always taking into account the possible risks and benefits associated with its use and being careful on its indication in fragile patients with high cardiovascular risk.

Dilatação fluxo-mediana da artéria braquail: aspectos técnicos, aplicabilidade e reprodutividade em ginecologia e obstetrícia / Flow-mediated dilatation of brachial artery: technical aspects, applicability and reproducibility in gynecology and obstetrics

A avaliação da dilatação fluxo-mediada da artéria braquial (DILA) tem-se incorporada na prática clínica como método capaz de contribuir no estudo das doenças arterioescleróticas. Estudos demonstraram que os valores de DILA são reduzidos em pacientes com pré-eclâmpsia, e que a redução desses valores está diretamente ligada à morbidade da doença. Outros estudos correlacionam diabetes gestacional e disfunção endotelial com redução do DILA nestas pacientes. Ainda, a terapia de reposição hormonal tem sido demonstrada como fator de melhora nos valores do DILA em pacientes na pós-menopausa. O objetivo deste estudo foi realizar uma revisão bibliográfica sobre a utilização do DILA em Ginecologia e Obstetrícia. Foi realizado um levantamento bibliográfico nas bases da Bireme, Scielo e PubMed, de trabalhos publicados entre 2013 e 2017. Podemos concluir que métodos não invasivos e de fácil execução, como o DILA, podem ter impactos relevantes ao identificar grupos de riscos e, assim, viabilizar medidas protetivas.(AU)

The evaluation of the flow-mediated dilation of the brachial artery (FMD) has been incorporated into clinical practice as a method capable of contributing to the study of arteriosclerotic diseases. Studies have shown that FMD values are reduced in patients with preeclampsia, and that the reduction in these values is directly associated with disease morbidity. Other studies correlate gestational diabetes and endothelial dysfunction with reduction of FMD in these patients. Furthermore, hormone replacement therapy has been demonstrated as an improvement fator in FMD values in postmenopausal patients. The objective of this study was to perform a bibliographic review on the use of FMD in Gynecology and Obstetrics. A bibliographical survey was carried out on the Bireme, Scielo and PubMed databases, of works published between 2013 and 2017. We can conclude that non-invasive and easy-to-execute methods, such as FMD, can have relevant impacts when identifying gropups of risk and thus make feasible measures protective.(AU)

Porfiria cutánea tarda: caso clínico / Porphyria cutanea tarda: case report

Porphyria cutanea tarda (PCT) is the most common type of porphyria: it is characterized by blistering lesions, erosions and crusts on the back of the hands, associated with photosensitivity and facial hypertrichosis. It is produced by acquired or hereditary deficiency of the enzyme UROD, fifth enzyme in the chain of production of the Heme group. This causes accumulation of porphyrins in the liver, which are subsequently mobilized to the skin, where lesions are generated by photosensitivity. This deficiency can be exacerbated by multiple causes. We report a 51-year-old female presenting with the characteristic dermal lesions described above, which disappeared when she discontinued her hormone replacement therapy with estradiol and dydrogesterone. Urinary and blood uroporphyrin and hexacarboxyl porphyrins were elevated and plasma ferritin was 479 ng/ml. Hormone replacement therapy was discontinued and phlebotomies were attempted but not tolerated by the patient. The dermic lesions have not relapsed.

Terapia hormonal en persona transgénero según world professional association for transgender health (WPATH) () y guías clinicas de la endocrine society. () / Hormone therapy in transgender person according to world professional association for transgender health (WPATH) and clinical guidelines of the endocrine society

RESUMEN La identidad de género es la percepción intrínseca de una persona de ser hombre, mujer o alguna alternativa de género. Las personas transgénero perciben estar en un cuerpo equivocado, ya que se sienten del sexo opuesto al biológico. Cuando esta incongruencia entre identidad de género y el fenotipo físico del sexo asignado, genera gran angustia, ansiedad y malestar persistente, se denomina disforia de género. Se estima que el 0,4%- 1.3% de la población mundial experimentan distintos grados de Disforia de Género. (3), no todas las personas con disforia de género tienen las mismas necesidades, por lo que la evaluación del objetivo personal para lograr bienestar es muy importante. Todas las intervenciones médicas conllevan riesgos, por lo que, la comprensión de éstos últimos, la adherencia y el manejo por profesionales capacitados los minimiza. En Revista de la Sociedad Chilena de Obstetricia y Ginecología Infantil y de la Adolescencia, recientemente hemos publicado dos artículos de revisión sobre la introducción a la Hormonoterapia en personas transgénero, objetivos de la terapia, transición en la adolescencia, y la transición masculino a femenino, por lo que éste escrito se concentrará sólo en los Riesgos de la Terapia Hormonal en la transición. (4,5)

SUMMARY Gender identity is the intrinsic perception of a person to be a man, woman or some gender alternative. Transgender people feel that they are in the wrong body, since they feel the opposite sex to the assigned. When this incongruence between gender identity and the physical phenotype generates great anguish, anxiety and persistent discomfort, it is called gender dysphoria. It is estimated that 0.4% −1.3% of the world population experience different degrees of Gender Dysphoria. (3), and not all people with gender dysphoria have the same needs, so the evaluation of the personal goal to achieve well-being is very important. All medical interventions involve risks, so the understanding of the latter, adherence and management by trained professionals minimizes them. In the Journal of the Chilean Society of Obstetrics and Child and Adolescent Gynecology, we have recently published two review articles on the introduction to Hormonotherapy in transgender people, objectives of therapy, transition in adolescence, and the male to female transition, so this writing will focus only on the Risks of Hormonal Therapy in the transition.

Métodos: Investigación comparativa y aplicada, con diseño no experimental, y prospectivo, que incluyo una muestra de 100 pacientes posmenopáusicas, evaluadas antes y después de 6 y 12 meses de recibir la terapia de reemplazo hormonal con Tibolona oral (2,5mg/día) por medio del cuestionario Menopause Rating Scale (MRS).Resultados: 94 mujeres completaron el protocolo de estudio, determinándose que antes de comenzar el tratamiento la mayoría presentaba síntomas somáticos, psicológicos y genitourinarios severos, mientras que al cabo de 12 meses de tratamiento hubo una mejoría significativa en todos los síntomas estudiados (P= 0.000). Asimismo, se evidenció una mejora significativa en la CV luego del tratamiento con Tibolona, expresada por una regresión de las mediasen las puntuaciones alcanzadas con el MRS entre la medición inicial, a los 6 y a los 12 meses; con un porcentaje de cambio en la CV de las pacientes participantes de -38,33% y -82.20% después de 6 y 12 meses de la intervención farmacológica, los cuales resultaron de relevancia clínica y significancia estadística (P= 0.000). Conclusión: La terapia hormonal sustitutiva con Tibolona mejora la CV de las pacientes posmenopáusicas en todas sus dimensiones, sobre todo en cuanto a la disminución de los síntomas somáticos.Palabras clave: calidad de vida, menopausia, terapia de reemplazo hormonal, tibolona(AU)

To compare the quality of life (QOL) in postmenopausal women before and after treatment with Tibolone attending at the gynaecological consultation in the "Maternidad Dr. Armando Castillo Plaza", Maracaibo, Venezuela. Methods: Comparative and applied research with quasi experimental and prospective design, which included a sample of 100 postmenopausal women, evaluated before and after 6 and 12 months receiving hormone replacement therapy with oral Tibolone (2,5mg/day) through the questionnaire Menopause Rating Scale (MRS). Results: 94 women completed the study protocol, it was found that before treatment the majority had most somatic, psychological and severe genitourinary, while after 12 months of treatment there was a significant improvement in all symptoms studied (P = 0.000 .) We also demonstrated a significant improvement in QOL after treatment with Tibolone, expressed by a regression of the means of the scores obtained with the MRS between the initial measurement, at 6 and 12 months, with a percentage change in the CV of the patients participating -38.33% -82.20% and after 6 and 12 months of pharmacological intervention, which were of clinical relevance and statistical significance (P = 0.000). Conclusion: Hormone replacement therapy with Tibolone improves QOL of the postmenopausal patients in all its dimensions, especially in terms of reduction in somatic symptoms(AU)

Association between asthma and female sex hormones / Associação entre asma e hormônios sexuais femininos

ABSTRACT CONTEXT AND OBJECTIVE: The relationship between sex hormones and asthma has been evaluated in several studies. The aim of this review article was to investigate the association between asthma and female sex hormones, under different conditions (premenstrual asthma, use of oral contraceptives, menopause, hormone replacement therapy and pregnancy). DESIGN AND SETTING: Narrative review of the medical literature, Universidade Federal do Tocantins (UFT) and Universidade Federal de São Paulo (Unifesp). METHODS: We searched the CAPES journal portal, a Brazilian platform that provides access to articles in the MEDLINE, PubMed, SciELO, and LILACS databases. The following keywords were used based on Medical Subject Headings: asthma, sex hormones, women and use of oral contraceptives. RESULTS: The associations between sex hormones and asthma remain obscure. In adults, asthma is more common in women than in men. In addition, mortality due to asthma is significantly higher among females. The immune system is influenced by sex hormones: either because progesterone stimulates progesterone-induced blocking factor and Th2 cytokines or because contraceptives derived from progesterone and estrogen stimulate the transcription factor GATA-3. CONCLUSIONS: The associations between asthma and female sex hormones remain obscure. We speculate that estrogen fluctuations are responsible for asthma exacerbations that occur in women. Because of the anti-inflammatory action of estrogen, it decreases TNF-α production, interferon-γ expression and NK cell activity. We suggest that further studies that highlight the underlying physiopathological mechanisms contributing towards these interactions should be conducted.

RESUMO CONTEXTO E OBJETIVO: A relação entre os hormônios sexuais e a asma tem sido investigada em diversos estudos. Esta revisão tem como objetivo descrever a relação entre hormônios sexuais (endógenos e exógenos) e a inflamação nas vias aéreas, especialmente na asma, em eventos diferentes (na asma pré-menstrual, durante o uso de anticoncepcionais, na menopausa, no uso de terapia hormonal e na gestação). TIPO DE ESTUDO E LOCAL: Revisão narrativa da literatura médica, Universidade Federal do Tocantins (UFT) e Universidade Federal de São Paulo (Unifesp). MÉTODO: Pesquisamos o Portal de Periódicos Capes, uma plataforma brasileira que fornece acesso a artigos nas bases de dados MEDLINE, PubMed, SciELO e LILACS. Os descritores utilizados foram asma, hormônios sexuais, mulheres e uso de anticoncepcionais, com base no "Medical Subject Headings". RESULTADOS: As associações entre hormônios sexuais e asma ainda permanecem obscuras. Em adultos, a asma é mais frequente em mulheres do que em homens. Além disso, a mortalidade por asma é significativamente maior no sexo feminino, destacando-se que o sistema imunológico sofre influência de hormônios sexuais, seja porque a progesterona estimula o fator bloqueador induzido pela progesterona e citocinas Th2 ou porque contraceptivos derivados de progesterona e estrógeno estimulam o fator de transcrição GATA-3. CONCLUSÕES: A associação entre asma e hormônios sexuais femininos permanece obscura. Nós especulamos que as flutuações do estrogênio são responsáveis pelas exacerbações da asma que ocorrem nas mulheres. Devido à ação anti-inflamatória do estrogênio há redução da produção de TNF-α, da expressão do interferon-γ e da atividade das células NK. Sugerimos que sejam realizados novos estudos para esclarecer os mecanismos fisiopatológicos dessas interações.

Sangramento anormal durante terapia hormonal na pré e perimenopausa: racional para manejo clínico / Abnormal bleeding during perimenopause hormone therapy: insights for clinical management

Este estudo tem como objetivo rever o estado da arte e racional para guiar a conduta no sangramento anormal durante a terapia hormonal combinada sequencial na perimenopausa. Antes de iniciar a terapia, é essencial excluir qualquer condição pélvica anormal, identificar as mulheres com maior risco de sangramento e moldar o regime às características clínico-laboratoriais de cada paciente. Na perimenopausa, particularmente na mulher que ainda mantém secreção ovariana de estrogênio ou mesmo estrogênio-progesterona, o regime de escolha é o combinado sequencial. Tatear a dose individualmente é recomendável nos primeiros meses de uso. Qualquer ação para parar o sangramento deve ser baseada na identificação correta da causa subjacente. É importante observar se o sangramento ocorre na fase estrogênica ou progestogênica da combinação utilizada, se o seu início foi precedido de longo tempo de sangramento normal, se houve introdução de medicação concomitante e se a ingesta tem sido regular. O tratamento consiste no ajuste da dose do estrogênio ou do progestogênio, na troca do progestogênio para outro com maior impacto sobre o endométrio, ou na troca do regime combinado sequencial para o combinado contínuo, como medida de exceção.(AU)

The current study aimed to review the state of art and provide a rational approach to the diagnosis and treatment of abnormal bleeding during combined sequential hormone therapy (HT). Before starting, it is essential to exclude any pelvic abnormal condition, to identify those women with higher risk of bleeding and to tailor the regimen to the needs of individual women. During perimenopause, particularly in women still keeping ovarian secretion, the choice is the combined sequential regimen. It is recommended to titer the dosis individually. Any action to stop the bleeding must be based on correct identification of the underlying cause. It is important to consider whether the bleeding started in the strogenic or progestogenic phases of the combined regimen, if the abnormal bleeding was preceded of long-term normal bleeding or if any concomitant medication was prescribed. The core treatment consists of estrogen/progestogen dose adjustment, change of the progestogen, or change of the sequential to the combined continuos regimen an exceptional measure.(AU)

Terapia de reemplazo hormonal en LES: caso clínico / Hormone replacement therapy in SLE: clinical case

El uso de estrógeno en pacientes con Lupus Eritematoso Sistémico (LES) sigue siendo un tema en discusión, debido a los múltiples efectos que esta hormona puede tener en el sistema inmune; entre los cuales incluso se ha postulado un rol promotor de esta enfermedad. Se presenta el caso de una paciente de 28 años con diagnóstico de LES, asociado a falla ovárica y osteoporosis en la cual se debe utilizar terapia de reemplazo hormonal (TRH) y se discuten sus posibles consecuencias.

Estrogen use in patients with Systemic Lupus Erythematosus (SLE) is still a matter under discussion, due to the multiple effects that this hormone can have on the immune system; it has been postulated a promoter role of this disease. The case of a patient of 28 years with a diagnosis of SLE associated with ovarian failure and osteoporosis in which to use hormone replacement therapy (HRT) and its possible consequences are discussed is presented.
