Abstract Background: hypovitaminosis D is frequent in kidney transplant recipient (KTR) patients and is associated with deleterious effects both at the bone and extraosseous levels. Treatment with cholecalciferol is effective for the normalization of 25(OH)D, demonstrating a beneficial effect on the calcium-tropic axis in other populations; however, its effect on the PTH/vitamin D/calcium and FGF23/klotho/phosphorus axis in RTR has not been reported. The aim of this study was to evaluate the effect of normalization of serum 25(OH)D concentrations on the PTH/vitamin D/calcium-FGF23/klotho/phosphorus axis in KTR treated with cholecalciferol, as well as the association between the components of this axis. Methods: a prospective study in 23 KTR with hypovitaminosis D, with evolution from 1 to 12 months post-transplantation, an estimated glomerular filtration rate > 60 mL/min/1.73 m2 and a history of primary nephropathy treated with cholecalciferol, in whom the PTH/vitamin D/calcium and FGF23/klotho/phosphorus axis was evaluated during the state of hypovitaminosis D and at normalization of 25(OH)D. Results: at the normalization of 25(OH)D, a reduction in PTH [103 (58.5-123.9) vs 45.6 (30.1-65.1) pg/mL; p = 0.002] and an increase in serum phosphorus [3.1 (2.3-3.5) vs 3.3 (3-3.6) mg/dL; p = 0.01] were evident, with no differences in calcium, klotho and FGF23 concentrations. The time to achieve normalization of 25(OH)D was 12 weeks (RIC, 4-12), with a dose of 5000 IU/day (RIC, 4000-6000). A positive association between klotho and PTH was corroborated (r = 0.54; p = 0.008; linear regression, β = 0.421; B = 0.004; 95 % CI, 0.003-0.007; p = 0.045). Conclusions: treatment with cholecalciferol is effective for the normalization of 25(OH)D, with a beneficial effect on calcium-phosphotropic metabolism characterized by a reduction in PTH concentration, without significant changes in calcemia or calciuria, as well as an increase in phosphatemia, without modifications in FGF23 or klotho concentrations.

Resumen Introducción: la hipovitaminosis D es frecuente en los receptores de trasplante renal (RTR) y se asocia con efectos deletéreos tanto a nivel óseo como extraóseo. El tratamiento con colecalciferol es eficaz para la normalización de la 25(OH)D, demostrándose un efecto benéfico sobre el eje calciotrópico; sin embargo, su efecto sobre el eje fosfotrópico no se ha reportado. El objetivo de este estudio fue evaluar el efecto de la normalización de las concentraciones séricas de 25(OH)D sobre el eje PTH/vitamina D/calcio-FGF23/klotho/fósforo en RTR tratados con colecalciferol, así como la asociación entre sus componentes. Métodos: estudio prospectivo en 23 RTR con hipovitaminosis D y antecedente de nefropatía primaria tratados con colecalciferol, en quienes se evaluó el eje PTH/vitamina D/calcio y FGF23/klotho/fósforo durante el estado de hipovitaminosis D y a la normalización de la 25(OH)D. Resultados: a la normalización de la 25(OH)D se evidenció una reducción de la PTH [103 (58,5-123,9) vs. 45,6 (30,1-65,1) pg/mL; p = 0,002] y un aumento del fósforo sérico [3,1 (2,3-3,5) vs. 3,3 (3-3,6) mg/dL; p = 0,01], sin diferencias en las concentraciones de calcio, klotho y FGF23. El tiempo para lograr la normalización de la 25(OH)D fue de 12 semanas (4-12), con una dosis de 5000 UI/día (4000-6000). Se corroboró una asociación positiva entre klotho y PTH (r = 0,54; p = 0,008; regresión lineal, β = 0,421; IC 95 %: 0,003-0,007; p = 0,045). Conclusiones: el tratamiento con colecalciferol es eficaz para la normalización de la 25(OH)D con un efecto benéfico sobre el metabolismo calcio-fosfotrópico caracterizado por una reducción de la PTH y un incremento de la fosfatemia, sin modificaciones de calcemia, calciuria, FGF23 o klotho.

Abstract Objective: To evaluate hypothalamic-pi- tuitary-gonadal (HPG) axis alterations at 1 and 12 months after kidney transplan- tation (KT) and their association with in- sulin resistance. Methods: A retrospective clinical study was conducted in a tertiary care center in kidney transplantation recipients (KTRs) aged 18- 50 years with primary kidney disease and stable renal graft function. LH, FSH, E2/T, and HOMA-IR were assessed at 1 and 12 months after KT. Results: Twenty-five KTRs were included; 53% were men, and the mean age was 30.6±7.7 years. BMI was 22.3 (20.4-24.6) kg/m2, and 36% had hypogonadism at 1 month vs 8% at 12 months (p=0.001). Re- mission of hypogonadism was observed in all men, while in women, hypogonadotropic hypogonadism persisted in two KTRs at 12 months. A positive correlation between go- nadotrophins and age at 1 and 12 months was evident. Fifty-six percent of patients had insulin resistance (IR) at 1 month and 36% at 12 months (p=0.256). HOMA-IR showed a negative correlation with E2 (r=- 0.60; p=0.050) and T (r=-0.709; p=0.049) at 1 month, with no correlation at 12 months. HOMA-IR at 12 months after KT correlated positively with BMI (r=0.52; p=0.011) and tacrolimus dose (r=0.53; p=0.016). Conclusion: Successful KT restores the HPG axis in the first year. Hypogonadism had a negative correlation with IR in the early pe- riod after KT, but it was not significant at 12 months.

Resumo Objetivo: Avaliar as alterações do eixo hipotálamo-hipófise-gonadal (HHG) em 1 e 12 meses após transplante renal (TR) e sua associação com a resistência à insulina. Métodos: Foi realizado um estudo clínico retrospectivo em um centro de cuidados terciários em receptores de transplante renal (RTR) com idade entre 18-50 anos com doença renal primária e função do enxerto renal estável. LH, FSH, E2/T e HOMA-IR foram avaliados em 1 e 12 meses após o TR. Resultados: foram incluídos 25 RTR; 53% eram homens e a média de idade foi de 30,6±7,7 anos. O IMC foi de 22,3 (20,4-24,6) kg/m2 e 36% apresentaram hipogonadismo em 1 mês vs 8% aos 12 meses (p=0,001). A remissão do hipogonadismo foi observada em todos os homens, enquanto nas mulheres, o hipogonadismo hipogonadotrófico persistiu em dois RTR aos 12 meses. Ficou evidente uma correlação positiva entre gonadotrofinas e idade em 1 e 12 meses. Cinquenta e seis por cento dos pacientes apresentaram resistência à insulina (RI) em 1 mês e 36% aos 12 meses (p=0,256). O HOMA-IR mostrou uma correlação negativa com E2 (r=-0,60; p=0,050) e T (r=-0,709; p=0,049) em 1 mês, sem correlação em 12 meses. O HOMA-IR aos 12 meses após TR correlacionou-se positivamente com o IMC (r=0,52; p=0,011) e a dose de tacrolimus (r=0,53; p=0,016). Conclusão: O TR bem-sucedido restaura o eixo HHG no primeiro ano. O hipogonadismo apresentou uma correlação negativa com a RI no período inicial após o TR, mas essa correlação não foi significativa aos 12 meses.

Abstract Background: Cardiovascular diseases are the leading cause of mortality worldwide and Mexico is no exception. The epidemiological data obtained in 1990 showed that cardiovascular diseases represented 19.8% of all causes of death in our country. This figure increased significantly to 25.5% for 2015. Some national surveys suggest that more than 60% of the adult population has at least one risk factor for cardiovascular disease (obesity or overweight, hypertension, smoking, diabetes, dyslipidemias). On the other hand, data from the Pan American Health Organization have linked the process of atherosclerosis as the first cause of premature death, significantly reducing life expectancy, which has enormous social repercussions. Objective: This document constitutes the Clinical Practice Guide (CPG) prepared at the initiative of the Mexican Society of Cardiology in collaboration with the Mexican Society of Nutrition and Endocrinology, AC, National Association of Cardiologists of Mexico, AC, Mexican Association for the Prevention of Atherosclerosis and its Complications, AC, National Normative Committee of General Medicine, AC, National College of Geriatric Medicine, AC, College of Internal Medicine of Mexico, AC, Mexican Society of Angiology and Vascular and Endovenous Surgery, AC, Mexican Institute of Research Nephrological, AC and the Mexican Academy of Neurology, A.C.; with the methodological support of the Ibero-American Agency for the Development and Evaluation of Health Technologies, in order to establish recommendations based on the best available evidence and agreed upon by an interdisciplinary group of experts. The objective of this document is to provide evidence-based recommendations to help decision makers in the diagnosis and treatment of dyslipidemias in our country. Material and methods: This document complies with international quality standards, such as those described by the Institute of Medicine of the USA, the Institute of Clinical Excellence of Great Britain, the Scottish Intercollegiate Guideline Network and the Guidelines International Network. A multidisciplinary group of clinical experts and methodologists with experience in systematic reviews of the literature and the development of clinical practice guidelines was formed. A scope document was agreed upon, relevant clinical questions were established, the best available evidence critically evaluated in systematic literature reviews was exhaustively identified, and clinical recommendations were developed. The modified Delphi Panel methodology was used to achieve an adequate level of consensus in each of the recommendations contained in this CPG. Results: 23 clinical questions were agreed upon which gave rise to their respective clinical recommendations. Conclusions: We consider that this document contributes to better clinical decision-making and becomes a point of reference for clinicians and patients in the management of dyslipidemias and this contributes to reducing the morbidity and mortality derived from atherosclerotic cardiovascular events in our country.

Abstract Introduction: In Mexico, neither the 36-item Short Form Health Survey (SF-36) nor the Bariatric Analysis and Reporting Outcome System (BAROS) instruments have been used to assess quality of life (QoL) before and after bariatric surgery (BS). Objective: To describe changes in QoL using the SF-36 and BAROS questionnaires in patients with severe obesity before and after BS. Methods: Clinical and anthropometric data of patients undergoing bariatric surgery between 2015 and 2016 were collected. Statistical significance was considered with a p-value < 0.05. Results: 230 patients were analyzed, 98 before and 132 and after BS; most were females (81 %). Initial body mass index was 48 kg/m2 (44-53). SF-36-measured QoL showed an increase in the physical component score from 43 to 54.2 points (p < 0.001), and in the mental component, from 53.3 to 56.6 points after BS. With BAROS, 98.5 % showed good to excellent QoL results within the first three months after BS. Conclusion: When measured with the SF-36 and BAROS questionnaires, QoL of Mexican patients with severe obesity was found to improve after BS.

Resumen Introducción: En México no se han utilizado los instrumentos Shorth Form 36 Items (SF-36) ni Baryatric Assesment Reporting Outcomes System (BAROS) para evaluar la calidad de vida (CV) antes y después de la cirugía bariátrica (CB). Objetivo: Describir los cambios en la CV con los cuestionarios SF-36 y BAROS, en pacientes con obesidad severa antes y después de la CB. Métodos: Se recolectaron los datos clínicos y antropométricos de pacientes sometidos a cirugía baríatrica entre 2015 y 2016. Se consideró con significación estadística una p < 0.05. Resultados: Se analizaron 230 pacientes, 98 y 132 antes y después de la CB; la mayoría fue del sexo femenino (81 %). El índice de masa corporal inicial fue de 48 kg/m2 (44-53). La CV medida con el SF-36 demostró un incremento en la puntuación del componente físico de 43 a 54.2 (p < 0.001) y en el componente mental, de 53.3 a 56.6 después de la CB. Con BAROS, en 98.5 % se registraron resultados buenos a excelentes en la CV en los primeros tres meses. Conclusión: Al ser medida con los cuestionarios SF-36 y BAROS se definió que la CV de los pacientes mexicanos con obesidad severa mejora después de la CB.

Abstract: Introduction: Hypothyroidism has been associated with dyslipidemia. Its treatment with levothyroxine has shown a positive effect on the lipid profile in adults, however, there is a lack of data on the pediatric popu lation. Objective: to evaluate the effect of the thyroid profile normalization on the lipid profile in children with primary hypothyroidism. Patients and Method: Retrospective study in children aged from 6 to 16 years, with diagnosis of primary hypothyroidism due to Hashimoto’s thyroiditis, in treatment with levothyroxine, and who had an evaluation of serum lipids before and during their treatment. The lipid profile was evaluated in 2 stages: the first one referred to as “before levothyroxine treatment” (at the diagnosis of primary hypothyroidism) and the second one referred to as “ thyroid profile normalization” (when normalization of Thyroid-stimulating hormone [TSH] and free T4 [FT4] was achieved during levothyroxine treatment). Sociodemographic and anthropometric data were recorded. The lipid profile evaluation consisted of the serum determination of total cholesterol (TC), high-density cholesterol (HDL-C), and TG. The phenotype of dyslipidemias was determined according to the Fredrickson’s classification. Results: 72 patients were included (61% women; age 11.5 ± 2.9 years), out of which 58.3% (n = 42) presented pre-treatment dyslipidemia. In hypothyroid state, it was evident the correlation of TSH with TC (r = 0.36; p = 0.002), LDL-C (r = 0.46; p = 0.01), and HDL-C (r = -0.33; p = 0.004). The thyroid profile normalization showed the reduction of TC [184 mg/dL (IQR 92-322) vs 147 mg/dL (IQR 92-283); p = 0.05], LDL-C [99 mg/dL (IQR 44-232) vs 82 mg/dL (IQR 41-168); p = 0.02], TG [113 mg/dL (IQR 50-483) vs 88 mg/dL (IQR 16-343); p = 0.03], and the frequency of dyslipidemia [58.3% vs 22.2%; p = 0.001), as well as the TC correction with TG (r = 0.35; p = 0.02) and LDL-C (r = 0.88; p = 0.01). Persistent dyslipidemia was associated with obesity (r = 0.27; p = 0.02), overweight (r = 0.58; p = 0.001), and pre-treatment dyslipidemia (r = 0.53; p = 0.001). Conclusions: There is an association between TSH, TC, LDL-C, and HDL-C in hypothyroidism. When the thyroid profile was normalized, there was a reduction of TC, TG, LDL- C, and dyslipidemia frequency. Persistent dyslipidemia was associated with obesity, overweight, and pre-treatment dyslipidemia.

Resumen: Introducción: El hipotiroidismo ha sido asociado con dislipidemia. Su tratamiento con levotiroxina ha mostrado un efecto positivo sobre el perfil lipídico en adultos, siendo poco descrito en población pediátrica. Objetivo: Evaluar el efecto de la normalización del perfil tiroideo sobre el perfil lipídico en niños con hipotiroidismo primario. Pacientes y Método: Estudio retrospectivo en niños de 6 a 16 años de edad, con diagnóstico de hipotiroidismo primario por tiroiditis de Hashimoto, en tratamiento con levotiroxina, y que contaron con evaluación de lípidos séricos antes y durante su tratamiento. Se evaluó el perfil lipídico en 2 tiempos: el primero, referido como “antes del tratamiento con levotiroxina” (al diagnóstico de hipotiroidismo primario) y el segundo, referido como “a la normalización del perfil tiroideo”. Se registraron datos sociodemográficos y antropométricos. La evaluación del perfil lipídico consistió en la determinación sérica de colesterol total (CT), colesterol de alta densidad (HDL-C) y TG. El fenotipo de las dislipidemias se caracterizó a través de la clasificación de Fredrickson. Resulta dos: Se incluyeron 72 pacientes (61% mujeres; edad de 11,5 ± 2,9 años), de los cuales 58,3% (n = 42) presentó dislipidemia pretratamiento. En estado hipotiroideo, se evidenció la correlación de TSH con CT (r = 0,36; p = 0,002), LDL-C (r = 0,46; p = 0,01) y HDL-C (r = -0,33; p = 0,004). A la normaliza ción del perfil tiroideo se evidenció la reducción de CT [184 mg/dL (RIC 92-322) vs 147 mg/dL (RIC 92-283); p = 0,05], LDL-C [99 mg/dL (RIC 44-232) vs 82 mg/dL (RIC 41-168); p = 0,02], TG [113 mg/dL (RIC 50-483) vs 88 mg/dL (RIC 16-343); p = 0,03] y de la frecuencia de dislipidemia [58,3% vs 22,2%; p = 0,001), así como la corrección de CT con TG (r = 0,35; p = 0,02) y LDL-C (r = 0,88; p = 0,01). La persistencia de dislipidemia se asoció con obesidad (r = 0,27; p = 0,02), sobrepeso (r = 0,58; p = 0,001) y dislipidemia pretratamiento (r = 0,53; p = 0,001). Conclusiones: Existe una asociación entre TSH, CT, LDL-C y HDL-C en hipotiroidismo. Al normalizarse el perfil tiroideo, se evidenció una reducción de CT, TG, LDL-C y frecuencia de dislipidemia. La dislipidemia persistente post-tratamiento se asoció con obesidad, sobrepeso y dislipidemia pretratamiento.

Abstract Introduction: Primary hyperparathyroidism (PHPT) is the leading cause of outpatient hypercalcemia associated with increased cardiovascular risk. The flow-mediated vasodilation (FMV) has been proposed as a non-invasive method for assessing endothelial function. Objective: To compare the endothelial dysfunction measured by FMV and diastolic dysfunction in patients with PHPT before and after parathyroidectomy. Method: We performed a quasi-experimental (before-after) study to evaluate diastolic function and FMV in patients with PHPT before and six months after parathyroidectomy. Results: Fifteen patients completed study: 12 women and 3 men; 73% presented lithiasis, 27% osteoporosis and 53% metabolic syndrome; 73% presented diastolic dysfunction before the surgery and 60% after the surgery (p = 0.09). Post-isquemia brachial diameter improved from 41 mm (before surgery) to 46 mm (after surgery; p = 0.020). After surgery, we also observed an increase in the brachial diameter pre vs. post-ischemia from 41 to 46 mm (p = 0.005). Before surgery, the change in the delta of brachial diameter pre and post-ischemia was 1 mm and up to 4 mm after surgery (p = 0.03). Conclusions: There is a minor endothelial dysfunction measured by FMV in patients who underwent surgery for PHPT at 6 months after surgery, as well as a trend towards improvement in diastolic dysfunction. Echocardiography can be useful in the preoperative evaluation in patients with asymptomatic PHPT.

Resumen Introducción: El hiperparatiroidismo primario (HPTP) es la principal causa de hipercalcemia ambulatoria y se ha asociado con un riesgo cardiovascular elevado. La vasodilatación mediada por flujo (VMF) es un método no invasivo que evalúa la función endotelial. Objetivo: Comparar la disfunción endotelial mediante VMF y la disfunción diastólica en pacientes con HPTP antes y después de la paratiroidectomía. Método: Mediante un estudio cuasiexperimental (antes-después) se evaluaron la función diastólica y la VMF antes y 6 meses después de realizar una paratiroidectomía. Resultados: Se incluyeron 15 pacientes con HPTP: 12 mujeres (80%) y 3 hombres (20%); el 73% presentaron litiasis, el 27% osteoporosis y el 53% síndrome metabólico; el 73% tenían disfunción diastólica antes de la cirugía y el 60% después de la cirugía (p = 0.09). Los diámetros braquiales post-isquemia mejoraron de 41 mm antes de la cirugía a 46 mm tras la cirugía (p = 0.020). Así mismo, los diámetros braquiales preisquemia vs. post-isquemia después de la cirugía mejoraron de 41 a 46 mm (p = 0.005). Antes de la cirugía, el cambio en la delta del diámetro braquial preisquemia y post-isquemia fue de 1 mm, y subió a 4 mm después de la cirugía (p = 0.03). Conclusiones: Existe una menor disfunción endotelial medida por VMF en pacientes posoperados por HPTP a los 6 meses de la cirugía. El estudio ecocardiográfico puede ser de utilidad en la evaluación preoperatoria de los pacientes con HPTP asintomáticos.

Resumen Introducción: Las patologías gastroesofágicas son comunes y multifactoriales en pacientes con diabetes tipo 1 (DM1). La evaluación por medio de panendoscopia y pHmetría es costosa y difícil de realizar en todos los centros de atención, por lo que se requieren algoritmos rentables para su diagnóstico. Existen cuestionarios sencillos y autoaplicables que pueden ser útiles para el diagnóstico de enfermedad por reflujo gastroesofágico en los pacientes con DM1. Objetivo: Evaluar la utilidad de los cuestionarios FSSG y Carlsson-Dent (CDQ) para detectar la enfermedad por reflujo gastroesofágico (ERGE) en pacientes con DM1. Métodos: Estudio transversal, se incluyeron 54 pacientes, elegidos al azar de la clínica de DMT1. Previo a la consulta, se les solicitó contestaran los cuestionarios FSSG y el CDQ, considerándose positivos para diagnóstico de ERGE los puntajes >8 y >4, respectivamente. Se analizaron y compararon las características bioquímicas y clínicas entre los pacientes con y sin síntomas de ERGE detectada por medio de los cuestionarios. Resultados: Los pacientes estudiados tenían edad de 29 años (22-35), 67% fueron mujeres, (mediana de diagnóstico de 16 años). El 39% de los pacientes tenían ERGE detectado mediante FSSG y 28% utilizando el cuestionario CDQ. El 71% de los pacientes reportó uso de medicamentos para reflujo. La concordancia entre ambos cuestionarios fue del 65% (p: <0.001). Pacientes que consumen tabaco y con descontrol glucémico, tenían más probabilidades de positividad en cualquier cuestionario. Conclusiones: Existe una alta prevalencia de ERGE en los pacientes con DM1. En esta población el cuestionario FSSG detectó a un mayor número de pacientes en comparación con el CDQ.

Abstract Background: Gastroesophageal pathologies are common and multifactorial in patients with type 1 diabetes (T1DM). The evaluation with endoscopy and 24 h pH esophageal monitoring is expensive and not always available in all medical centers, especially in developing countries so more cost-effective algorithms for diagnosis are required. Clinical questionnaires are easy to apply but its utility for gastroesophageal reflux disease screening in patients with long standing T1DM must be analyzed. Objective: To evaluate the utility of the FSSG and Carlsson-Dent (CDQ) questionnaires to detect the frequency of gastroesophageal reflux disease in patients with T1DM. Methods: Analytic cross-sectional study, included 54 randomly selected patients from the T1DM clinic in our hospital. Before their routine evaluation, were asked to answer FSSG and CDQ questionnaires, classifying them as positive with a score >8 or >4, respectively. we associated and compared the clinical and biochemical characteristics between patients with or without gastroesophageal reflux detected through questionnaires. Results: Median age was 29 years (22-35), 67% were female (median of 16 years from diagnosis). In 39% of the patients FSSG was positive, CDQ was positive in 28%. A total of 71% of patients were taking medications to treat non-specific gastric symptoms. The concordance between questionnaires was 65% (p: <0.001). Those patients with tobacco consumption as well as those with poor glycemic control were more likely to score positive in either questionnaire. Conclusions: Patients T1DM had a high prevalence of gastroesophageal reflux disease. In those patients FSSG questionnaire detected a higher number of patients in comparison with CDQ.

Abstract Background: Non-functional pituitary adenomas generally have a benign and non-invasive nature, however, it may show aggressiveness with invasion of surrounding tissues, high mitotic index, an index of Ki67> 3% and extensive positive staining for the cellular tumor antigen p53, differing from the pituitary carcinomas by the absence of craniospinal dissemination or systemic metastases. Aggressive adenomas show resistance to surgical, medical and radiation therapy, including chemotherapeutic agents such as temozolomide, a promising therapeutic option according to reports in the international literature. Case presentation: This is a woman in her 6th decade of life with a clinical presentation characterized by a progressive chiasm syndrome and hypopituitarism in the presence of non-functional pituitary macroadenoma, with initial resistance of neurosurgical treatment, medical treatment with a dopaminergic agonist plus a somatostatin receptor agonist and conventional fractionated radiotherapy, meeting the criteria of aggressive pituitary adenoma. After the treatment with temozolomide as a chemotherapy regimen, the patient showed clinical stability and absence of tumor progression during her follow-up. Conclusion: Defining aggressiveness is of crucial importance for improving the management of patients by enhancing prognostic predictions and effectiveness of treatment. The treatment of nonfunctioning pituitary adenomas with aggressiveness is a clinical challenge that involves a multidisciplinary approach. Resistance to surgical, medical and radiotherapeutic treatment have resulted in the investigation of therapeutic options with chemotherapeutic agents such as temozolomide, with promising response rates.

Resumen Antecedentes: Los adenomas hipofisarios no funcionales generalmente tienen un comportamiento benigno y naturaleza no invasiva, sin embargo, pueden mostrar características de agresividad con invasión a tejidos circundantes, alto índice mitótico, un índice de Ki67 > 3%y positividad extensa para la tinción de p53, diferenciándose de los carcinomas hipofisarios por la ausencia de diseminación cerebroespinal o metástasis a distancia. Los adenomas agresivos muestran resistencia al tratamiento guirúrgico, médico y radioterapia, y los agentes guimioterapéuticos como temozolamida son una opción terapéutica prometedora de acuerdo con los reportes de la literatura médica internacional. Caso clínico: Paciente del sexo femenino en la sexta década de la vida con padecimiento caracterizado por síndrome guiasmático progresivo e hipopituitarismo ante la presencia de un macroadenoma hipofisario no funcional, con resistencia a tratamiento neuroguirúrgico inicial, tratamiento médico con un agonista dopaminérgico y análogo de receptor de la somatostatina así como radioterapia convencional fraccionada, y cumple con los criterios de agresividad. Se establece tratamiento guimioterapéutico a base de temozolamida, y durante su vigilancia muestra tanto estabilidad clínica como ausencia de progresión tumoral. Conclusiones: La determinación de agresividad es de crucial importancia para mejorar el tratamiento del paciente y, con ello, ofrecer un mejor pronóstico y efectividad terapéutica. El tratamiento de los adenomas hipofisarios no funcionales con características de agresividad es un reto clínico gue involucra un abordaje multidisciplinario. La resistencia al tratamiento quirúrgico, médico y radioterapéutico han dado lugar a la investigación de opciones terapéuticas con agentes quimioterapéuticos como la temozolamida, con tasas de respuesta prometedoras.

Abstract Hyperthyroidism is a common condition that is easily recognized by its signs and symptoms. The apathetic hyperthyroidism is a form of presentation of hyperthyroidism without its characteristic signs and symptoms. The cardinal symptoms of apathetic hyperthyroidism are depression and apathy. The absence of classical signs and symptoms of hyperthyroidism delays the diagnosis and treatment of the disease, as it is often misdiagnosed as a primary psychiatric disorder. It is more common in elderly patients and is extremely rare in children and middle-age adults. We report the case of a middle-age woman with apathetic hyperthyroidism characterized by depression, dizziness, edema and weight loss without other clinical data of hyperthyroidism; she had been treated for two years for major depressive disorder. She had been studied by other specialties because of vertigo. The diagnosis was made after thyroid function tests were requested, and joined with clinical findings.

Resumen El hipertiroidismo es una patología frecuente que suele ser fácilmente reconocida por sus síntomas y signos. El hipertiroidismo apático es una forma de presentación de hipertiroidismo sin signos y síntomas característicos. Los síntomas cardinales del hipertiroidismo apático son la depresión y apatía; por ello, la ausencia de síntomas y signos clásicos retrasa el diagnóstico y el tratamiento, pues a menudo se diagnostica erróneamente como un trastorno psiquiátrico primario. Es más frecuente en pacientes de edad avanzada y es extremadamente rara en niños y adultos de mediana edad. Reportamos el caso de una mujer de mediana edad con hipertiroidismo apático caracterizado por depresión, vértigo, edema y pérdida de peso, sin otros datos clínicos de hipertiroidismo. Durante dos años recibió tratamiento por depresión, y adicionalmente fue estudiada en otras especialidades por vértigo. El diagnóstico se estableció mediante pruebas de función tiroidea y la integración con las características clínicas.
