RESUMEN

Type 2 diabetes mellitus (T2DM) is associated with a heightened risk of cardiovascular and renal complications. While glycemic control remains essential, newer therapeutic options, such as SGLT2 inhibitors, offer additional benefits beyond glucose reduction. This review delves into the mechanisms underlying the cardio-renal protective effects of SGLT2 inhibitors. By inducing relative hypoglycemia, these agents promote ketogenesis, optimize myocardial energy metabolism, and reduce lipotoxicity. Additionally, SGLT2 inhibitors exert renoprotective actions by enhancing renal perfusion, attenuating inflammation, and improving iron metabolism. These pleiotropic effects, including modulation of blood pressure, reduction of uric acid, and improved endothelial function, collectively contribute to the cardiovascular and renal benefits observed with SGLT2 inhibitor therapy. This review will provide clinicians with essential knowledge, understanding, and a clear recollection of this pharmacological group's mechanism of action.

RESUMEN

INTRODUCTION: Bariatric surgery is established as a possibility for the treatment of obesity, allowing weight reduction and remission of obesity comorbidities. Reported suboptimal clinical response rates are as high as 30-60% (insufficient weight loss or gain, defined as BMI greater than 35 kg/m2 or excess weight loss less than 50%). Proximal jejuno-ileal bypass (PJIBP) is a promising option when re-intervention is required. OBJECTIVES: To describe the standardization of a proprietary technique of modified PJIBP as a management procedure in patients with post-gastric bypass recurrent weight gain or insufficient post-intervention weight loss. METHODS: This study evaluated a case series of 10 Latin American patients requiring post-bariatric re-intervention, between February 2018 and 2023, in a single-metabolic surgery center in Cali-Colombia. RESULTS: Median age was 45 years (26-70 RIC), 60% female, and 40% male. Mean BMI at conversion was 36.7 kg/m2 (6.4 SD). Median follow-up was 22 months (RIC 16-30). Mean percentage of excess weight lost was 78% (22.4 SD). One hundred percent achieved glycemia control, only one patient persisted with dyslipidemia, and no patient presented hypoalbuminemia. At the end of follow-up, 100% received vitamin supplementation. CONCLUSION: PJIBP could be an effective procedure, associated with positive results in relation to weight loss and resolution of obesity comorbidities. Deficiencies of fat-soluble vitamins and protein malnutrition represent the main concern in the long term, so multidisciplinary management and continuous follow-up are required.

RESUMEN

Introducción: parte esencial del manejo y control de la pandemia por SARS-CoV-2 ha sido la vacunación. Sin embargo, las sales de aluminio usadas en las vacunas para potenciar el sistema inmune, pueden asociarse con el síndrome autoinmune/autoinflamatorio inducido por adyuvantes (ASIA). Esta condición se ha relacionado con otros factores, como agentes infecciosos, implantes de silicona e inoculación de aceites minerales. Hay poca información acerca de enfermedades endocrinas autoinmunes y ASIA después de la vacunación para SARS-CoV-2. Objetivo: reportar los casos relacionados con enfermedad tiroidea posterior a la vacunación para COVID-19, en pacientes que asistieron a la consulta de endocrinología en la clínica Imbanaco, Cali, Colombia, en 2021. Métodos: descripción clínica, de laboratorio e imágenes de 8 pacientes que acudieron a la consulta de endocrinología. Resultados y discusión: 87.5% eran de sexo femenino de 46.8 ± 10 años, el tiempo entre la aplicación de la vacuna y la aparición de los síntomas fue 13.8 días y la vacuna más relacionada fue Pfizer/BioNTech seguida por Sinovac-CoronaVac y AstraZeneca/AZD1222. La presentación de tiroiditis subaguda estuvo presente en el (37.5%), enfermedad de Graves (37.5%), tiroiditis silente (12.5%) e hipotiroidismo (12.5%). Los síntomas más comunes fueron mialgias y palpitaciones. El hallazgo ecográfico más común fue tiroiditis subaguda. Conclusiones: en esta seria de casos, reportamos una relación entre la vacunación y la aparición de enfermedad tiroidea por SARS-CoV-2. dado que estos eventos son motivo de controversia, serán necesarios otros estudios que ayuden a establecer si existe o no causalidad

Introduction: Vaccines have been an essential part of the SARS-CoV-2 pandemic management and control. However, aluminum salts in vaccines, used to enhance the immune response, may be associated with autoimmune/inflammatory syndrome induced by adjuvants (ASIA). This syndrome has been linked to other factors, such as infectious agents, silicone implants, and mineral oil inoculation. Data on autoimmune endocrine disorders and ASIA following SARS-CoV-2 vaccination is scant. Objective: to report cases of thyroid disorders following COVID-19 vaccination, in patients who attended the endocrinology clinic at Clínica Imbanaco, Cali, Colombia, in 2021. Methods: clinical, laboratory and imaging description of 8 patients who attended the endocrinology service. Results and discussion: 87.5% were females, aged 46.8 ± 10 years. Time between vaccine administration and symptoms onset was 13.8 days and the most related vaccine was the Pfizer/BioNTech vaccine followed by Sinovac-CoronaVac and AstraZeneca/AZD1222 vaccines. Subacute thyroiditis presented in 37.5%, Graves ́ disease in 37.5%, silent thyroiditis in 12.5% and hypothyroidism in 12.5%. Myalgias and palpitations were the most common symptoms. Subacute thyroiditis was the most common ultrasound finding. Conclusions: our case series evidences a relationship between thyroid disease and SARS-CoV-2 vaccination. Given controversy remains, further studies will be necessary to establish causality.

RESUMEN

Resumen ANTECEDENTES: La coexistencia de hiperglucemia y embarazo se asocia con morbilidad, mortalidad y riesgo cardiometabólico para la madre y su hijo. En el año 2010, la International Association of the Diabetes and Pregnancy Study Groups (IADPSG) estableció una clasificación, aceptada por la Organización Mundial de la Salud (OMS) y la International Federation of Gynecologt and Obstetrics (FIGO) en el 2013, en la que se consideran las semanas de gestación al diagnóstico de hiperglucemia y las concentraciones séricas de glucosa en diferentes escenarios. OBJETIVO: Actualizar los escenarios de clasificación de la hiperglucemia en la embarazada y documentar, de acuerdo con lo soportado en la evidencia, su repercusión clínica. METODOLOGÍA: Búsqueda bibliográfica en las bases de datos PubMed, Google Académico y Clinicalkey de artículos publicados entre los años 2008 a 2022, que contuvieran las palabras clave (MESH): "gestational diabetes" e "hyperglycemia in pregnancy" que posteriormente se filtraron conforme a su contenido específico definido en los criterios de inclusión (estudios epidemiológicos, de diagnóstico y clasificación de la hiperglucemia en el embarazo y de desenlaces maternos y perinatales en coexistencia con hiperglucemia en el embarazo). RESULTADOS: Se identificaron 25,886 artículos, de los que solo 24 cumplieron con los criterios de inclusión (8 observacionales descriptivos, 2 de revisión sistemática y metanálisis, 13 revisiones de la bibliografía y consensos globales, y 1 ensayo clínico aleatorizado). CONCLUSIÓN: Clasificar a la hiperglucemia en diferentes escenarios clínicos es importante para su debido diagnóstico, orientación clínica, estudios adicionales y tratamiento temprano.

Abstract BACKGROUND: Hyperglycemia in pregnancy is associated with perinatal maternal morbidity and mortality and cardiometabolic risk for the mother and her offspring. In 2010, the International Diabetes and Pregnancy Study Group (IADPSG) established a classification, accepted by the World Health Organization (WHO) and the International Federation of Gynecology and Obstetrics (FIGO) in 2013, considering gestational age. diagnosis and serum glucose levels to be classified in different scenarios. OBJECTIVE: To update the classification scenarios of hyperglycemia in pregnant women and to document, in accordance with what is supported by the evidence, its clinical impact. MATERIALS AND METHODS: The PubMed, Google Scholar, and Clinicalkey databases were searched with the MESH terms ("gestational diabetes," "hyperglycemia in pregnancy"), subsequently filtered according to specific content, defined in the inclusion criteria (studies on epidemiology, diagnosis and classification of hyperglycemia in pregnancy and studies on maternal and perinatal outcomes in hyperglycemia in pregnancy) all articles published between 2008 and 2022. RESULTS: 25,886 articles were identified, 24 of these met the inclusion criteria; eight were descriptive observational, two systematic reviews and meta-analyses, thirteen reviews of the literature and global consensus, and one randomized clinical trial. CONCLUSION: Classifying hyperglycemia within the different clinical scenarios is important for its approach, clinical orientation, additional studies if required, and early management interventions.

RESUMEN

Resumen ANTECEDENTES: El hipertiroidismo, en concurrencia con el embarazo, tiene una incidencia variable en los distintos trimestres de la gestación y puerperio. Predomina en el primer trimestre y a los 7 a 9 meses posparto. Se relaciona, principalmente, con enfermedad de Graves e hiperémesis gravídica por las concentraciones de gonadotropina coriónica humana. A partir del surgimiento de la infección por SARS-CoV-2 se documentó la asociación entre ambas enfermedades. CASO CLÍNICO: Paciente de 27 años, primigesta, con antecedente familiar materno de hipotiroidismo, con reporte de TSH pregestacional normal (2.3 mUI/mL). Al cabo de cuatro semanas de embarazo tuvo una infección no complicada por SARS-CoV-2, con prueba diagnóstica positiva de PCR. El diagnóstico y el tratamiento farmacológico fueron oportunos y se logró el estado eutiroideo que permitió suspender la medicación y mantener asintomática a la paciente desde el punto de vista endocrino. A las 36 semanas de embarazo se le diagnosticó preeclampsia severa, por lo que se decidió finalizar el embarazo mediante cesárea, con recién nacido masculino de 2550 g y 47 cm, sin complicaciones. En el seguimiento posparto la función tiroidea permaneció eutiroidea. CONCLUSIONES: En la paciente del caso fue aparente la relación entre la COVID-19 en el embarazo y el hipertiroidismo. El caso es de interés clínico porque permite analizar otros factores causales de la enfermedad tiroidea en el embarazo.

Abstract BACKGROUND: Hyperthyroidism associated with pregnancy has a variable incidence in different trimesters of pregnancy and puerperium. It predominates in the first trimester and at 7 to 9 months postpartum. It is mainly associated with Graves' disease and hyperemesis gravidarum due to human chorionic gonadotropin concentrations. Since the emergence of SARS-CoV-2 infection, the association between the two diseases has been documented. CLINICAL CASE: 27-year-old primigravida with a maternal family history of hypothyroidism and a reported normal pregestational TSH (2.3 mIU/mL). Four weeks into her pregnancy, she had an uncomplicated SARS-CoV-2 infection with a positive diagnostic PCR test. Diagnosis and pharmacologic treatment were timely, and euthyroid status was achieved, allowing discontinuation of the medication and keeping the patient asymptomatic from an endocrine standpoint. At 36 weeks' gestation, she was diagnosed with severe pre-eclampsia, and it was decided to terminate the pregnancy by cesarean section, with a male newborn weighing 2550 g and 47 cm without complications. At postpartum follow-up, thyroid function remained euthyroid. CONCLUSIONS: In the case patient, the association between COVID-19 in pregnancy and hyperthyroidism was evident. The case is of clinical interest because it allows the analysis of other causal factors of thyroid disease in pregnancy.

RESUMEN

Resumen OBJETIVO: Estimar la cantidad de pacientes con irregularidades menstruales que se embarazaron luego de una cirugía bariátrica (manga gástrica) y describir los desenlaces de los embarazos. MATERIALES Y MÉTODOS: Estudio retrospectivo de serie de casos de pacientes obesas y con irregularidades menstruales intervenidas mediante cirugía bariátrica (manga gástrica). Se operaron entre el 1 de junio de 2014 y el 31 de diciembre de 2019 en el Centro Médico Imbanaco Cali, Colombia. RESULTADOS: De 1418 cirugías bariátricas, tipo manga gástrica, 117 pacientes cumplieron con los criterios de inclusión, 80 de ellas se localizaron telefónicamente y aceptaron incluirse al estudio. Luego de la manga gástrica, el 86.25% (n = 69) de las pacientes logró la regularización de sus ciclos menstruales. Además, el 31% (n = 25) consiguió el embarazo, 80% (n = 20) de ellas tenían la intención de buscar el embarazo. Los desenlaces de esos embarazos fueron favorables, con partos a término, con adecuado peso y talla al nacer. CONCLUSIONES: Después de la cirugía bariátrica, tipo manga gástrica, en mujeres con irregularidades menstruales, 25 de las 80 pacientes se embarazaron y los desenlaces obstétricos fueron satisfactorios. Sin duda, hacen falta más estudios prospectivos para poder afirmar, con una mejor representación estadística, las repercusiones de la disminución del peso corporal en la tasa de fertilidad.

Abstract OBJECTIVE: To estimate the number of patients with menstrual irregularities who became pregnant after bariatric surgery (gastric sleeve) and to describe the pregnancy outcomes. MATERIALS AND METHODS: Retrospective study of a series of cases of obese patients with menstrual irregularities who underwent bariatric surgery (gastric sleeve). They were operated between June 1, 2014 and December 31, 2019 at the Imbanaco Cali Medical Center, Colombia. RESULTS: Of 1418 bariatric surgeries, gastric sleeve type, 117 patients met the inclusion criteria, 80 of them were located by telephone and agreed to be included in the study. After gastric sleeve, 86.25% (n = 69) of the patients achieved regularization of their menstrual cycles. In addition, 31% (n = 25) achieved pregnancy, 80% (n = 20) of them intended to seek pregnancy. The outcomes of these pregnancies were favorable, with full-term deliveries, with adequate weight and height at birth. CONCLUSIONS: After bariatric surgery, gastric sleeve type, in women with menstrual irregularities, 25 of the 80 patients became pregnant and the obstetric outcomes were satisfactory. Undoubtedly, more prospective studies are needed to be able to affirm, with a better statistical representation, the repercussions of the decrease in body weight on the fertility rate.

RESUMEN

A thunderclap headache (TCH) is defined as an excruciating headache which occurs abruptly like "thunder," reaches its maximum point in less than a minute, and should be considered a medical emergency. Below, we present the clinical case of a 49-year-old Colombian patient who developed a thunderclap headache as the initial sign of pituitary apoplexy. He progressed satisfactorily, with no evidence of sequelae, highlighting the early diagnosis of a potentially fatal entity. (Acta Med Colomb 2022; 47. DOI:https://doi.org/10.36104/amc.2022.2336).

La cefalea tipo trueno (CT) es considerada un dolor de cabeza intolerable, el cual se produce de forma abrupta como un "trueno", alcanza su punto máximo en menos de un minuto después de su aparición, y debe considerarse una emergencia médica. A continuación presentamos el caso clínico de un paciente colombiano, de 49 años quien presenta cefalea tipo trueno como manifestación inicial de apoplejía hipofisaria, con adecuada evolución y sin evidencia secuelar, resaltando el diagnóstico temprano en una entidad potencialmente mortal. (Acta Med Colomb 2022; 47. DOI:https://doi.org/10.36104/amc.2022.2336).

RESUMEN

AIMS: Describe the local characteristics, methodology and results of the registry of acromegalic patients in Colombia (RAPACO). METHODS: Multicenter, retrospective study based on the registry of acromegalic patients in Colombia: RAPACO. The data collected included: demographics, diagnosis, approximate time of disease evolution, data on weight, height, body mass index (BMI), neck circumference (NC) abdominal circumference (AC) hip circumference (HC) and waist/hip ratio (WHR); clinical and biochemical data at the time of diagnosis, etiology, immunohistochemistry of the tumor and information related to types of treatment. Descriptive analytics were employed. RESULTS: A total of 201 patients (60% females) with an average age at registration of 49.5 ± 14.6 years and an average time of evolution of the disease of 6.96 ± 4.5 years. Average weight was 75.1 Kg ± 12.98, with an average BMI of 28.11 ± 4.33. The most frequent symptoms mentioned at the time of diagnosis were extremity enlargement and headache. The most frequent comorbidity was arterial hypertension in 50.3% of the cases. 78.6% of cases were caused by macroadenoma. 80.1% received surgical treatment, 77.6% were under medical treatment, of which 95.7% were receiving somatostatin analogues. 26.4% of patients were treated with radiation therapy. Of the patients who received any type of clinical treatment, only 2.5% reported biochemical control at registration. CONCLUSION: It is important to recognize the local epidemiological, clinical, biochemical and treatment characteristics in order to assist in further understanding this pathology to implement local measures to improve both the quality of life as well as the prognosis of the patients diagnosed.
