Renin–angiotensin–aldosterone system blockers effect in chronic kidney disease progression in hypertensive elderly patients without proteinuria: PROERCAN trial / Efecto de los bloqueantes del sistema renina-angiotensina-aldosterona en la progresión de enfermedad renal crónica en pacientes hipertensos añosos sin proteinuria: ensayo clínico Progresión de Enfermedad Renal Crónica en Ancianos

Introduction: Evidence about nefroprotective effect with RAAS blockers in elderly patients with chronic kidney disease (CKD) without proteinuria is lacking. The primary outcome of our study is to evaluate the impact of RAAS blockers in CKD progression in elderly patients without proteinuria. Materials and methods: Multicenter open-label, randomized controlled clinical trial including patients over 65 year-old with hypertension and CKD stages 3–4 without proteinuria. Patients were randomized in a 1:1 ratio to either receive RAAS blockers or other antihypertensive drugs and were followed up for three years. Primary outcome is estimated glomerular filtration rate (eGFR) decline at 3 years. Secondary outcome measures include BP control, renal and cardiovascular events and mortality. Results: 88 patients were included with a mean age of 77.9±6.1 years and a follow up period of 3 years: 40 were randomized to RAAS group and 48 to standard treatment. Ethiology of CKD was: 53 vascular, 16 interstitial and 19 of unknown ethiology. In the RAAS group eGFR slope during follow up was −4.3±1.1ml/min, whereas in the standard treatment group an increase on eGFR was observed after 3 years (+4.6±0.4ml/min), p=0.024. We found no differences in blood pressure control, number of antihypertensive drugs, albuminuria, potassium serum levels, incidence of cardiovascular events nor mortality during the follow up period. Conclusions: In elderly patients without diabetes nor cardiopathy and with non proteinuric CKD the use of RAAS blockers does not show a reduction in CKD progression.

Introducción: Actualmente no existe suficiente evidencia sobre el efecto nefroprotector de los bloqueantes del sistema renina-angiotensina-aldosterona (BSRAA) en pacientes añosos con enfermedad renal crónica (ERC) sin proteinuria y sin cardiopatía. El objetivo es evaluar el efecto de los BSRAA en la progresión de la ERC en este grupo poblacional. Métodos: Se trata de un estudio prospectivo, aleatorizado, que compara la eficacia de los BSRAA vs. otros tratamientos antihipertensivos en la progresión renal en personas mayores de 65 años con ERC estadios 3 y 4 e índice albúmina/creatinina<30mg/g. Aleatorización 1:1 BSRAA o tratamiento antihipertensivo estándar. Se recogieron cifras tensionales y parámetros analíticos de un año previo a la aleatorización y durante el seguimiento. Resultados: Se incluyeron 88 pacientes seguidos durante tres años con edad media de 77,9±6,1 años. De estos, se aleatorizaron 40 al grupo BSRAA y 48 al estándar. La etiología de ERC fue: 53 vascular, 16 intersticial y 19 no filiada. En el primer grupo se observó una progresión de la ERC con una caída del filtrado glomerular estimado (FGe) de -4,3±1,1mL/min, mientras que en el grupo estándar un aumento del FGe durante el seguimiento de 4,6±0,4mL/min, p=0,024. No se apreciaron diferencias entre ambos en el control tensional, el número de antihipertensivos, la albuminuria, los niveles de potasio, la incidencia de eventos cardiovasculares ni la mortalidad durante el seguimiento. Conclusiones: En pacientes añosos no diabéticos con ERC no proteinúrica y sin cardiopatía el uso de BSRAA no añade beneficio en la progresión de la ERC.

Concomitant treatment with safinamide and antidepressant drugs: Safety data from real clinical practice / Tratamiento concomitante de safinamida y antidepresivos: Datos de seguridad sobre la práctica en la vida real

Background and purpose: The aim of this study was to assess the possible pharmacological interactions between safinamide and antidepressants, and in particular the appearance of serotonin syndrome with data from real life. Methods: We conducted a retrospective observational study of patients with Parkinson's disease from our Movement Disorders Unit, who were under treatment with any antidepressant drug and safinamide. Specifically, symptoms suggestive of serotonin syndrome were screened for. Also, we collected time of simultaneous use, doses of levodopa and other antiparkinsonian drugs. Results: Clinical records were reviewed for the study period of September 2018 to September 2019. Seventy-eight PD patients who were treated with safinamide of which 25 (32.05%) had a concomitant treatment with an antidepressant drug, being sertraline and escitalopram the most frequent. Mean age was 80 years ± 8.43 and H&Y stage was 3 [2–4]. Mean dose of levodopa used was 703.75 mg ± 233.15. Median duration of concomitant treatment with safinamide and antidepressant drug was 6 months (IQR 20.5), and over eighteen months in 5 cases. No case of serotonin syndrome was recorded, neither was any of its typical manifestations combined or in isolation. Conclusions: Our real clinical practice study suggests that concomitant use of safinamide with antidepressant drugs in PD patients seemed to be safe and well tolerated, even in the long term. However, caution is warranted, individualizing treatment regimens and monitoring the potential appearance of adverse effects.(AU)

Material y métodos: Realizamos un estudio observacional retrospectivo de pacientes con enfermedad de Parkinson (EP) de nuestra unidad de trastornos del movimiento, que estaban en tratamiento con algún fármaco antidepresivo y safinamida. Específicamente, se examinaron los síntomas sugestivos de síndrome serotoninérgico. Además, se recogieron tiempos de uso simultáneo, dosis de levodopa y otros fármacos antiparkinsonianos concomitantes. Resultados: Se revisaron las historias clínicas correspondientes al período de estudio de septiembre de 2018 a septiembre de 2019. Setenta y ocho pacientes con EP se encontraban en tratamiento con safinamida, de los cuales 25 (32,05%) se encontraban recibiendo además un fármaco antidepresivo, siendo sertralina y escitalopram los más frecuentes. La edad media fue de 80 años ± 8,43 y el estadio H&Y fue de 3 [2-4]. La dosis media de levodopa utilizada fue de 703,75 mg ± 233,15. La mediana de duración del tratamiento concomitante con safinamida y un fármaco antidepresivo fue de 6 meses (IQR: 20,5), y más de 18 meses en 5 casos. No se registró ningún caso de síndrome serotoninérgico, ni tampoco ninguno de sus síntomas de forma aislada. Conclusión: Nuestro estudio de práctica clínica real sugiere que el uso concomitante de safinamida con fármacos antidepresivos en pacientes con EP parece ser seguro y bien tolerado, incluso a largo plazo. Sin embargo, es necesaria precaución, individualizando los regímenes de tratamiento, y controlando la posible aparición de efectos adversos.(AU)

Intra and inter-rater remote assessment of bradykinesia in Parkinson's disease / Evaluación remota de la bradicinesia en la enfermedad de Parkinson mediante análisis intra e inter evaluadores

Introduction: Reliable assessment of individuals with Parkinson's disease (PD) is essential for providing adequate treatment. Clinical assessment is a complex and time-consuming task, especially for bradykinesia, since its evaluation can be influenced by the degree of experience of the examiner, patient collaboration and individual bias. Improvement of the clinical evaluation can be obtained by considering assessments from several professionals. However, this is only true when inter and intra-rater agreement are high. Recently, the Movement Disorder Society highlighted, during the COVID-19 pandemic, the need to develop and validate technologies for remote assessment of the motor status of people with PD. Thus, this study introduces an objective strategy for the remote evaluation of bradykinesia using multi-specialist analysis. Methods: Twelve volunteers with PD participated and these were asked to execute finger tapping, hand opening/closing and pronation/supination movements. Each task was recorded and rated by fourteen PD health experts for each patient. The scores were assessed on an individual basis. Intra and inter-rater agreement and correlation were estimated. Results: The results showed that agreements and correlations between experienced examiners were high with low variability. In addition, group analysis was noted as possessing the potential to solve individual inconsistency bias. Conclusion: Furthermore, this study demonstrated the need for a group with prior training and experience, along with indicating the importance for the development of a clinical protocol that can use telemedicine for the evaluation of individuals with PD, as well as the inclusion of a specialized mediating group. In Addition, this research helps to the development of a valid remote assessment of bradykinesia.(AU)

Introducción: La evaluación confiable de las personas con la enfermedad de Parkinson (EP) es esencial para lograr con un tratamiento adecuado. La evaluación clínica es una tarea compleja y que requiere mucho tiempo, especialmente para la bradicinesia, ya que su evaluación puede verse influenciada por el grado de experiencia del examinador, la colaboración del paciente y el sesgo individual. La mejora de la evaluación clínica se puede obtener considerando las evaluaciones de varios profesionales. Sin embargo, esto solo es más preciso cuando el convenio intra e inter evaluadores es alto. Recientemente, la Sociedad de Trastornos del Movimiento destacó, durante la pandemia COVID-19, la necesidad de desarrollar y validar tecnologías para la evaluación remota del estado motor de las personas con EP. Por lo tanto, este estudio presenta una estrategia objetiva para la evaluación remota de la bradicinesia mediante un análisis multi evaluadores. Métodos: Participaron 12 voluntarios con EP y se les pidió que ejecutaran movimientos de golpeteo de dedos de las manos, movimientos con las manos y pronación-supinación de las manos. Cada ejecución del movimiento fue registrado y calificado por 14 expertos en salud. Las puntuaciones se evaluaron de forma individual. Se estimó el convenio y la correlación intra e inter evaluadores. Resultados: Los resultados mostraron que los convenios y las correlaciones inter evaluadores experimentados son altos con baja variabilidad. Además, se observó que el análisis de grupo posee el potencial de resolver el sesgo de inconsistencia individual. Conclusiones: De esta forma, este estudio demostró la necesidad de un grupo con formación y experiencia previa, señalando la importancia para el desarrollo de un protocolo clínico que utiliza la telemedicina para la evaluación de personas con EP y como la inclusión de un grupo mediador especializado. En realidad, esta investigación propone una evaluación remota eficaz de la bradicinesia.(AU)

COVID 19 and myoclonus, do hemodialysis patients have more risk?

We discuss two recent cases from our hospital in which two patients with ESKD receiving periodical hemodialysis (HD) and SarS-Cov-2 infection suffered movement disorders, being the onset related to the HD sessions in both. First case is a 78 year-old woman who is admitted with generalized myoclonic status epilepticus and second case is a 46 year-old male who starts repeatedly suffering myoclonus during his hemodialysis sessions on day +10 after testing positive (asymptomatic infection). There are two main hypotheses when it comes to myoclonus and CNS disorders in COVID19, post-hypoxic origin and inmunomediated postinfectious origin. We wonder if they could both be interacting in patients with kidney disease, and especially in those who receive hemodialysis, maximizing the risk of suffering this type of disorders.

Left ventricular concentric remodeling in COPD patients: A cross-sectional observational study.

OBJECTIVE: To investigate the association between left ventricular structure and disease severity in COPD patients. METHODS: Twenty-eight COPD patients were stratified according to the disease severity, using the BODE index, into Lower (n=17) and Higher (n=11) groups, composed of patients with lower severity (BODE <5) and higher severity (BODE ≥5), respectively. Left ventricle (LV) was assessed by 2D-echocardiography. BODE index was calculated using body mass index (BMI); forced expiratory volume in the first second (FEV1, %); modified Medical Research Council (mMRC) and distance walked during 6-minute walk test (6MWD). RESULTS: Patients in the Higher group showed lower oxygen arterial saturation (p=0.02), FEV1 (p<0.01) and 6MWD (p=0.02) and higher value of relative posterior wall thickness (RWT) compared to Lower group (p=0.02). There were significant associations between LV end-systolic diameter (LVESD) and BODE index (r=-0.38, p=0.04), LV end-diastolic diameter (LVEDD) and FEV1 (r=0.44, p=0.02), LVEDD and BMI (r=0.45, p=0.02), LVESD and BMI (r=0.54, p=0.003) and interventricular septal thickness and 6MWD (r=-0.39, p=0.04). CONCLUSIONS: More severe COPD patients, BODE score ≥5, may have higher RWT, featuring a possible higher concentric remodeling of LV in this group. Besides that, a greater disease severity may be related to LV chamber size reduction.

Multiple and hereditary renal tumors: a review for radiologists.

80% of renal carcinomas (RC) are diagnosed incidentally by imaging. 2-4% of "sporadic" multifocality and 5-8% of hereditary syndromes are accepted, probably with underestimation. Multifocality, young age, familiar history, syndromic data, and certain histologies lead to suspicion of hereditary syndrome. Each tumor must be studied individually, with a multidisciplinary evaluation of the patient. Nephron-sparing therapeutic strategies and a radioprotective diagnostic approach are recommended. Relevant data for the radiologist in major RC hereditary syndromes are presented: von-Hippel-Lindau, Chromosome-3 translocation, BRCA-associated protein-1 mutation, RC associated with succinate dehydrogenase deficiency, PTEN, hereditary papillary RC, Papillary thyroid cancer- Papillary RC, Hereditary leiomyomatosis and RC, Birt-Hogg-Dubé, Tuberous sclerosis complex, Lynch, Xp11.2 translocation/TFE3 fusion, Sickle cell trait, DICER1 mutation, Hereditary hyperparathyroidism and jaw tumor, as well as the main syndromes of Wilms tumor predisposition. The concept of "non-hereditary" familial RC and other malignant and benign entities that can present as multiple renal lesions are discussed.

A Palearctic view of a bat fungal disease.

The fungal infection causing white-nose disease in hibernating bats in North America has resulted in dramatic population declines of affected species, since the introduction of the causative agent Pseudogymnoascus destructans. The fungus is native to the Palearctic, where it also infects several bat species, yet rarely causes severe pathology or the death of the host. Pseudogymnoascus destructans infects bats during hibernation by invading and digesting the skin tissue, resulting in the disruption of torpor patterns and consequent emaciation. Relations among pathogen, host, and environment are complex, and individuals, populations, and species respond to the fungal pathogen in different ways. For example, the Nearctic Myotis lucifugus responds to infection by mounting a robust immune response, leading to immunopathology often contributing to mortality. In contrast, the Palearctic M. myotis shows no significant immunological response to infection. This lack of a strong response, resulting from the long coevolution between the hosts and the pathogen in the pathogen's native range, likely contributes to survival in tolerant species. After more than 15 years since the initial introduction of the fungus to North America, some of the affected populations are showing signs of recovery, suggesting that the fungus, hosts, or both are undergoing processes that may eventually lead to coexistence. The suggested or implemented management methods of the disease in North America have encompassed, for example, the use of probiotics and fungicides, vaccinations, and modifying the environmental conditions of the hibernation sites to limit the growth of the pathogen, intensity of infection, or the hosts' responses to it. Based on current knowledge from Eurasia, policy makers and conservation managers should refrain from disrupting the ongoing evolutionary processes and adopt a holistic approach to managing the epizootic.

Vista paleártica de una enfermedad fúngica de murciélagos Resumen La enfermedad fúngica que produce el síndrome de nariz blanca en murciélagos en hibernación en Norte América ha resultado en declinaciones poblacionales dramáticas en las especies afectadas desde la introducción del agente causante, Pseudogymnoascus destructans. El hongo es nativo del Paleártico, donde también infecta a varias especies de murciélagos; sin embargo, raramente causa patología severa o la muerte del hospedero. Pseudogymnoascus destructans infecta a los murciélagos durante la hibernación invadiendo y digiriendo el tejido de la piel, lo que resulta en la disrupción de los patrones de torpor y la consecuente emaciación. Las relaciones entre el patógeno, el huésped y el ambiente son complejas, y los individuos, las especies y poblaciones responden al patógeno fúngico de distintas maneras. Por ejemplo, Myotis lucifugus, especie del Neártico, responde a la infección montando una respuesta inmune robusta, produciendo una inmunopatología que a menudo contribuye a la mortalidad. En contraste, M. myotis del Paleártico no presenta respuesta inmunológica significativa a la infección. La falta de una fuerte respuesta, resultado de la larga coevolución entre hospederos y el patógeno en el rango nativo de distribución del patógeno, probablemente contribuye a la supervivencia en especies tolerantes. Después de más de 15 años desde la introducción del hongo en Norte América, algunas de las poblaciones afectadas están mostrando señales recuperación, lo que sugiere que el hongo, hospederos, o ambos, están pasando por procesos que eventualmente pueden conducir a la coexistencia. Los métodos de manejo de la enfermedad sugeridos o implementados en Norte América han abarcado, por ejemplo, el uso de probióticos y fungicidas, vacunaciones y modificación de las condiciones ambientales de los sitios de hibernación para limitar el crecimiento del patógeno, la intensidad de la infección o las respuestas de los hospederos. Con base en conocimiento actual de Eurasia, los formuladores de políticas y los manejadores de la conservación deberían abstenerse de alterar los procesos evolutivos en curso y adoptar un enfoque holístico para gestionar la epizootia.

Strategies for prevention and treatment of SARS-COV-2 infection in patients with chronic kidney disease: Literature review.

COVID-19 has proven to be particularly aggressive in patients with chronic kidney disease (CKD). The lower immune response rate and the greater susceptibility to progress to severe forms of the disease have contributed to this phenomenon, which has persisted in the post-vaccination era of the pandemic. Paradoxically, CKD has been excluded from most clinical trials of the main therapeutic tools developed against SARS-CoV-2. However, experience in the use of these drugs has been accumulating in different stages of CKD, supporting their use with guarantees of efficacy and safety. The objective of this review is to gather all treatment indications for COVID-19 in the different phases of the disease, tailored to CKD in its various stages, including renal replacement therapy.

Effectiveness and safety of adalimumab biosimilar in patients with inflammatory bowel disease.

BACKGROUND: Adalimumab biosimilar MSB11022 (Idacio ®) has been approved for the same indications as its originator (Humira ®), based on findings from clinical trials in plaque psoriasis. Data on its efficacy and safety in inflammatory bowel disease, however, are scarce. METHODS: Retrospective, observational study of 44 patients with inflammatory bowel disease: 30 were treated with originator adalimumab, 5 were directly started on MSB11022, and 9 switched from originator to biosimilar adalimumab. To evaluate the effectiveness of the use of adalimumab in inflammatory bowel disease, both laboratory markers (fecal calprotectin and C-reactive protein) and scales that measure the activity of inflammatory bowel disease using specific scales (Harvey-Bradshaw Index (HBI) have been usEd.) for Crohn's disease and Mayo Score for Ulcerative Colitis. Efficacy was evaluated by recording the adverse effects that could occur with the administration of adalimumab (original or biosimilar). The success of the switch was determined by analyzing meaningful differences in effectiveness and safety criteria. Concomitant therapy and the need for dose intensification were also analyzed. Objective of this study was to assess the effectiveness and safety of biosimilar adalimumab in adalimumab-naïve patients and patients switched from originator adalimumab. RESULTS: No significant differences were observed in clinical disease activity (P=.317) or biochemical parameters [fecal calprotectin (P=.445) and C-reactive protein P=.661)] after the switch from the originator adalimumab to MSB11022. There was not a significant reduction in the concomitant use of corticosteroids and thiopurines (P=.157). No emergency room visits or hospitalizations were observed during the study period and none of the patients experienced serious adverse effects. CONCLUSIONS: Between originator adalimumab and biosimilar-start cohorts, no differences were observed, between originator adalimumab and switch cohorts, no significant differences were found either, and with the pre- and post-switch to biosimilar comparison, 2 of the 9 patients experienced AEs after the switch. The biosimilar showed a favorable safety profile (one patient with a serious adverse effect (rash) with biosimilar discontinued treatment) and no significant changes to clinical or biochemical parameters were observed after the switch.

Ambulatory blood pressure monitoring. Current status and future perspectives. / Monitorización ambulatoria de la presión arterial. Situación actual y perspectivas futuras.

Ambulatory Blood Pressure Monitoring (ABPM) is considered the best method for obtaining a reliable estimation of the true blood pressure. Average values obtained during the whole 24-hour period, or during daytime and nighttime periods are better correlated with the risk of mortality and cardiovascular disease compared to clinic or office blood pressure. Indeed, nighttime blood pressure, a measure only obtained through ABPM, is the most powerful risk predictor. ABPM is complementary to clinic blood pressure measurement and allows the definition of blood pressure phenotypes, such as "white-coat or masked hypertension, when clinic and ABPM measurements show discrepancy in normal values. Additional potentially relevant features include blood pressure variability, such as nocturnal blood pressure decline, morning surge or short-term variability, as determined by standard deviation or the coefficient of variation.

Targeting metabolic-associated fatty liver disease in diabetic kidney disease: A call to action.

Nonalcoholic fatty liver disease or metabolic-associated fatty liver disease (MAFLD) is a common condicion with increasing prevalence and incidence, specially in patients with type 2 diabetes mellitus (T2DM). Both cardiovascular and renal disease are clearly increased in these patients, particularly in those with diabetic nephropathy. In the liver-heart-kidney-metabolic axis, the common pathophysiological basis of MAFLD, cardiovascular disease (CVD), chronic kidney disease (CKD), and T2DM is the same. The clinical relationship between all of them is clear and is multidirectional: MAFLD may precede the development of cardiovascular and renal disease, and may also worsen the prognosis of these complications once developed. In this review we emphasize the importance of targeting MAFLD in Diabetic kidney disease, with the goal of detecting high-risk patients in order to improve their prognosis.

Effect of SGLT2 inhibitors on anemia and their possible clinical implications.

Sodium-glucose cotransporter 2 inhibitors (SGLT2i) have demonstrated cardiovascular and renal benefits in patients with type 2 diabetes mellitus, heart failure, or chronic kidney disease. Since the first studies with these drugs, an initial increase in hemoglobin/hematocrit levels was observed, which was attributed to an increase in hemoconcentration associated with its diuretic effect, although it was early appearent that these drugs increased erythropoietin levels and erythropoiesis, and improved iron metabolism. Mediation studies found that the increase in hemoglobin was strongly associated with the cardiorenal benefits of these drugs. In this review, we discuss the mechanisms for improving erythropoiesis and the implication of the increase in hemoglobin on the cardiorenal prognostic benefit of these drugs.

Prevalence and prognostic meaning of interstitial lung abnormalities in remote CT scans of patients with interstitial lung disease treated with antifibrotic therapy.

OBJECTIVES: To describe the prevalence and characteristics of interstitial lung abnormalities (ILA) in CT scans performed prior to the initiation of antifibrotics in a series of patients with interstitial lung disease (ILD), and to identify characteristics apparent on early CT scans that could help to predict outcomes. METHODS: We conducted a retrospective observational study. The original cohort consisted of 101 patients diagnosed with ILD and treated with antifibrotics in a tertiary hospital. Patients were included if they had a thoracic CT scan performed at least one year before initiation of therapy. They were classified radiologically in three groups: without ILA, with radiological ILA and extensive abnormalities. ILA were classified as subpleural fibrotic, subpleural non-fibrotic and non-subpleural. The initial scan and the latest CT scan performed before treatment were read for assessing progression. The relationship between CT findings of fibrosis and the radiological progression rate and mortality were analyzed. RESULTS: We included 50 patients. Only 1 (2%) had a normal CT scan, 25 (50%) had extensive alterations and 24 (48%) had radiological criteria for ILA, a median of 98.2 months before initiation of antifibrotics, of them 18 (75%) had a subpleural fibrotic pattern. Significant bronchiectasis and obvious honeycombing in the lower zones were associated with shorter survival (p = 0.04). Obvious honeycombing in the lower zones was also significantly (p < 0.05) associated with a faster progression rate. CONCLUSIONS: Fibrotic ILAs are frequent in remote scans of patients with clinically relevant ILD, long before they require antifibrotics. Findings of traction bronchiectasis and honeycombing in the earliest scans, even in asymptomatic patients, are related to mortality and progression later on.

High-fat diet promotes coagulation and endothelial activation in Sprague Dawley rats: Short-term effects of combined oral contraceptives / Dieta alta en grasas promueve la coagulación y la activación endotelial en ratas Sprague Dawley: efectos a corto plazo de los anticonceptivos orales combinados

Background Combined oral contraceptives (COCs), use in individuals are associated with increased risk of thrombotic events. This highlights the significance of assessing the impact of COC on promoting coagulation and endothelial activation in high-fat diet (HFD)-fed Sprague Dawley rats. Methods Twenty (20) five-weeks-old female Sprague Dawley rats weighing between 150 and 200g were subjected to both LFD and HFD-feeding for 8-weeks to determine its influence on basic metabolic status, hemostatic profile, hemodynamic parameters (blood pressure and heart rate), as well as selected biomarkers of coagulation (tissue factor and D-dimer) and endothelial activation (Von Willebrand factor and nitric oxide). Thereafter HFD-fed animals were treated with receive high dose combined oral contraceptive (HCOC) and low dose combine oral contraceptive (LCOC) for 6 weeks. Results Our results showed that beyond weight gain, HFD-feeding was associated with hyperglycemia, increased mean arterial pressure, and reduced nitric oxide levels when compared with LFD group (p<0.05). Interestingly, treatment with high dose of COC for 6-weeks did not significantly alter atherothrombotic markers (p>0.05). However, this study is not without limitation as regulation of these markers remains to be confirmed within the cardiac tissues or endothelial cells of these animals. Conclusion HFD-feeding orchestrate the concomitant release of pro-coagulants and endothelial activation markers in rats leading to haemostatic imbalance and endothelial dysfunction. Short-term treatment with COC shows no detrimental effects in these HFD-fed rats. Although in terms of clinical relevance, our findings depict the notion that the risk of CVD in association with COC may depend on the dosage and duration of use among other factors especially in certain conditions. ...

Antecedentes El uso de anticonceptivos orales combinados (AOC) en individuos se asocia con un mayor riesgo de eventos trombóticos. Esto resalta la importancia de evaluar el impacto de los AOC en la promoción de la coagulación y la activación endotelial en ratas Sprague Dawley alimentadas con una dieta alta en grasas (HFD). Métodos Veinte (20) ratas Sprague Dawley hembra de 5semanas de edad con un peso entre 150-200g fueron tratadas mediante una alimentación con dieta baja en grasas (LFD) y alta en grasas (HFD) durante 8 semanas para determinar su influencia en el estado metabólico básico, perfil hemostático, parámetros hemodinámicos (presión arterial y frecuencia cardíaca), así como biomarcadores seleccionados de coagulación (factor tisular y D-dímero) y activación endotelial (factor de von Willebrand y óxido nítrico). Posteriormente, los animales alimentados con HFD fueron tratados con dosis alta de anticonceptivo oral combinado (AOC-AL) y dosis baja de anticonceptivo oral combinado (AOC-BL) durante 6 semanas. Resultados Nuestros resultados mostraron que, además del aumento de peso, la alimentación con HFD se asoció con hiperglucemia, aumento de la presión arterial media y niveles reducidos de óxido nítrico en comparación con el grupo LFD (p<0,05). Curiosamente, el tratamiento con dosis alta de AOC durante 6 semanas no alteró significativamente los marcadores aterotrombóticos (p>0,05). Sin embargo, este estudio no está exento de limitaciones, ya que la regulación de estos marcadores aún debe confirmarse en los tejidos cardíacos o las células endoteliales de estos animales. Conclusión La alimentación con HFD orquesta la liberación concomitante de procoagulantes y marcadores de activación endotelial en ratas, lo que conduce a un desequilibrio hemostático y disfunción endotelial. El tratamiento a corto plazo con AOC no muestra efectos perjudiciales en estas ratas alimentadas con HFD. ... (AU)

Prevención cardiovascular en la diabetes mellitus. ¿Es adecuado hablar de riesgo moderado o intermedio? / Cardiovascular prevention in diabetes mellitus. Is it appropriate to speak of moderate or intermediate risk?

La diabetes, especialmente la tipo 2, está considerada como una situación de riesgo de enfermedad cardiovascular aterosclerosa (ECVA). Los sujetos con diabetes tipo 2 tienen una mortalidad por ECVA 3 veces superior a la de la población general, atribuida a la hiperglucemia y a la frecuente asociación de otros factores de riesgo cardiovascular, como la dislipidemia aterogénica. Numerosas sociedades científicas han establecido una clasificación de riesgo de ECVA en la diabetes basada en 3 grados (moderado, alto y muy alto). Los objetivos del control de la dislipidemia están claramente definidos y aceptados, y varían dependiendo del riesgo cardiovascular previamente establecido. En el riesgo moderado o intermedio, las guías proponen una intervención menos intensiva, manteniendo cifras de c-LDL<100mg/dL y de c-no-HDL<130mg/dL, y esperar 10 años hasta alcanzar la categoría de alto riesgo para iniciar un tratamiento más intensivo. Sin embargo, durante la década de seguimiento preconizada en las guías, el depósito de colesterol en la pared arterial va aumentando, facilitando el desarrollo de una placa de ateroma inestable e inflamatoria, y el desarrollo de ECVA. Alternativamente, se podría considerar desde el inicio que la diabetes conlleva una situación de alto riesgo y el objetivo debería ser c-LDL<70mg/dL. Además, mantener cifras de c-LDL<70mg/dL contribuye a reducir y estabilizar la placa de ateroma, evitando o disminuyendo episodios de mortalidad por ECVA durante esos años de evolución de la diabetes. ¿Deberíamos mantener los objetivos propuestos en los sujetos con diabetes y riesgo moderado durante una década hasta alcanzar la fase de alto riesgo cardiovascular o, por el contrario, adoptar desde el inicio una postura más intensiva buscando reducir el riesgo cardiovascular en la mayoría de los pacientes con diabetes? ¿Es mejor esperar o prevenir con medidas terapéuticas efectivas desde el primer momento?

Diabetes, especially type 2, is considered a risk situation for atherosclerotic cardiovascular disease (ASCVD). Subjects with diabetes type 2 have a mortality rate due to ASCVD 3 times higher than that found in the general population, attributed to hyperglycemia and the frequent association of other cardiovascular risk factors, such as atherogenic dyslipidemia. Numerous scientific societies have established a risk classification for ASCVD in diabetes based on 3 degrees (moderate, high and very high). The objectives of dyslipidemia control are clearly defined and accepted, and vary depending on the previously established cardiovascular risk. In moderate or intermediate risk, the guidelines propose a less intensive intervention, maintaining LDL-C levels<100mg/dL and NO-HDL-C levels<130mg/dL, and waiting 10 years until reaching the high-risk category to initiate more intensive treatment. However, during the decade of follow-up recommended in the guidelines, cholesterol deposition in the arterial wall increases, facilitating the development of an unstable and inflammatory atheromatous plaque, and the development of ASCVD. Alternatively, diabetes could be considered from the outset to be a high-risk situation and the goal should be LDL-C<70mg/dL. Furthermore, maintaining LDL-C levels<70mg/dL contributes to reducing and stabilizing atheromatous plaque, avoiding or reducing mortality episodes due to ASCVD during those years of diabetes evolution. Should we maintain the proposed objectives in subjects with diabetes and moderate risk for a decade until reaching the high cardiovascular risk phase or, on the contrary, should we adopt a more intensive stance from the beginning seeking to reduce cardiovascular risk in the majority of patients with diabetes? Is it better to wait or prevent with effective therapeutic measures from the first moment? (AU)
