ABSTRACT

El hiperaldosteronismo primario (HAP) es una causa importante de hipertensión arterial (HTA) secundaria. El estudio del mismo precisa de una alta sospecha clínica, además de un estudio hormonal que confirme la hipersecreción hormonal. Es importante iniciar el tratamiento adecuado una vez se confirma el diagnóstico, y para ello es preciso demostrar si la hipersecreción hormonal es unilateral (pacientes que podrían ser tributarios a tratamiento quirúrgico) o bilateral (pacientes que son tributarios a tratamiento únicamente farmacológico). En el Hospital del Mar desde el año 2016 existe un equipo de trabajo multidisciplinar en el que participan nefrólogos, endocrinólogos, radiólogos y cirujanos para evaluar los casos con sospecha de hiperaldosteronismo y consensuar el mejor abordaje diagnóstico-terapéutico de estos pacientes, incluyendo la necesidad de cateterismo venoso adrenal, que es una técnica que en los últimos años se ha erigido como gold standard para el estudio del HAP. En el presente estudio recogemos la experiencia de nuestro centro en la realización de cateterismo venoso adrenal y en la utilidad de este para el manejo de tales pacientes (AU)

It is important to start the appropriate treatment once the diagnosis is confirmed, and for this is necessary to demonstrate whether the hormonal hypersecretion is unilateral (patients who could be candidates for surgical treatment) or bilateral (patients who are candidates for pharmacological treatment only). At the Hospital del Mar since 2016 there has been a multidisciplinary work team in which Nephrologists, Endocrinologists, Radiologists and Surgeons participate to evaluate cases with suspected hyperaldosteronism and agree on the best diagnostic-therapeutic approach for these patients, including the need for adrenal vein sampling, which is a technique that in recent years has become the gold standard for the study of PAH. In the present study we collect the experience of our center in performing adrenal vein catheterization and its usefulness for the management of these patients (AU)

ABSTRACT

Introducción: La hipertensión arterial resistente (HTAR) supone un importante impacto a nivel multiorgánico e incrementa la morbimortalidad. Este trabajo evalúa la evolución de la lesión orgánica mediada por hipertensión en pacientes con HTAR tras añadir espironolactona. Material y métodos: Estudio retrospectivo de 58 pacientes con HTAR a quienes se añadió espironolactona (12,5-25mg/día). Se obtuvieron parámetros de presión arterial clínica y MAPA-24h, cociente albúmina/creatinina y datos ecocardiográficos previos a iniciar espironolactona y tras 12 meses de tratamiento. Resultados: El 36,2% de los pacientes eran mujeres y la edad media de 67,3±10,1 años. Se objetivó un descenso en albuminuria (mediana [RIC25-75]) de 27,0 (7,5-255,4) a 11,3 (3,1-37,8) mg/g (p = 0,009), siendo más marcado en pacientes con albuminuria grado A2 y A3: de 371,2 (139,5-797,4) a 68,4 (26,5-186,5) mg/g, p =0,02.. A nivel ecocardiográfico se evidenció: pared posterior: −1,0±0,4mm (p<0,001), tabique interventricular: −0,6±0,5mm (p=0,01), índice de masa del ventrículo izquierdo (VI): −14,7±10,2g/m2 (p=0,006), índice de remodelado del VI: −0,04±0,036 (p=0,03), sin cambios estadísticamente significativos en fracción de eyección VI, diámetro diastólico VI, diámetro sistólico VI, diámetro de aurícula izquierda, relación entre onda de llenado ventricular temprano y contracción auricular ni en índice de presión llenado VI. La presión arterial clínica sistólica/diastólica presentó un descenso de −12,5±4,9/−4,9±3,0mmHg, p<0,001. En los MAPA-24h se observó un descenso significativo de presión arterial sistólica y diastólica en los períodos diurno y nocturno, y un cambio favorable en el patrón circadiano en el 38,1% de los pacientes, p<0,001. Conclusiones: Añadir espironolactona en HTAR contribuye a la reducción de la lesión orgánica mediada por hipertensión a nivel de albuminuria y de parámetros ecocardiográficos de cardiopatía hipertensiva.

Introduction: Resistant hypertension (RH) represents an important multi-organic impact and increases the morbi-mortality. We aimed to evaluate the evolution of hypertensive mediated organ damage in patients with RH after adding spironolactone. Material and methods: Retrospective study of 58 patients with RH who started spironolactone (12.5–25mg daily). Office blood pressure, 24-h ambulatory blood pressure monitoring (24h-ABPM), urine albumin-to-creatinine ratio and echocardiographic parameters were analyzed prior to initiation of spironolactone and after 12 months of treatment. Results: Thirty-six percent of patients were women and mean age was 67.3±10.1 years. We observed a decrease in urine albumin-to-creatinine ratio (median [RIQ25–75]) of 27.0 (7.5-255.4) to 11.3 (3.1–37.8) mg/g, P = .009. This was more relevant in patients with albuminuria grade A2 and A3: 371.2 (139.5–797.4) to 68.4 (26.5–186.5) mg/g, P = .02. The echocardiographic changes were: posterior wall thickness: −1.0±0.4mm (P<.001), interventricular septal thickness: −0.6±0.5mm (P=.01), left ventricular (LV) mass index: −14.7±10.2g/m2 (P=.006), LV remodeling index: −0.04±0.036 (P=.03), without statistically significant changes in LV ejection fraction, LV end-diastolic diameter, LV end-systolic diameter, left atrial diameter, relationship between early ventricular filling wave and atrial contraction and LV filling pressure index. Systolic/diastolic office blood pressure decreased −12.5±4.9/−4.9±3.0mmHg, P<.001. In 24h-ABPM, systolic and diastolic BP had a significant decrease in diurnal and nocturnal periods and 38.1% of patients presented a favorable change in the circadian pattern, P<.001. Conclusions: Adding spironolactone to patients with RH contributes to improve hypertensive mediated organ damage by reducing albuminuria levels and echocardiographic parameters of hypertensive heart disease.

ABSTRACT

Obesity-related hyperfiltration leads to an increased glomerular filtration rate (GFR) and hyperalbuminuria. These changes are reversible after bariatric surgery (BS). We aimed to explore obesity-related renal changes post-BS and to seek potential mechanisms. Sixty-two individuals with severe obesity were prospectively examined before and 3, 6 and 12 months post-BS. Anthropometric and laboratory data, 24 h-blood pressure, renin-angiotensin-aldosterone system (RAS) components, adipokines and inflammatory markers were determined. Both estimated GFR (eGFR) and albuminuria decreased from the baseline at all follow-up times (p-for-trend <0.001 for both). There was a median (IQR) of 30.5% (26.2-34.4) reduction in body weight. Plasma glucose, glycosylated hemoglobin, fasting insulin and HOMA-index decreased at 3, 6 and 12 months of follow-up (p-for-trend <0.001 for all). The plasma aldosterone concentration (median (IQR)) also decreased at 12 months (from 87.8 ng/dL (56.8; 154) to 65.4 (56.8; 84.6), p = 0.003). Both leptin and hs-CRP decreased (p < 0.001) and adiponectine levels increased at 12 months post-BS (p = 0.017). Linear mixed-models showed that body weight (coef. 0.62, 95% CI: 0.32 to 0.93, p < 0.001) and plasma aldosterone (coef. -0.07, 95% CI: -0.13 to -0.02, p = 0.005) were the independent variables for changes in eGFR. Conversely, glycosylated hemoglobin was the only independent variable for changes in albuminuria (coef. 0.24, 95% CI: 0.06 to 0.42, p = 0.009). In conclusion, body weight and aldosterone are the main factors that mediate eGFR changes in obesity and BS, while albuminuria is associated with glucose homeostasis.

ABSTRACT

Arterial stiffness (AS) is an independent predictor of cardiovascular risk. We aimed to analyze changes (Δ) in AS 1-month post-bariatric surgery (BS) and search for possible pathophysiological mechanisms. Patients with severe obesity (43% hypertensives) were prospectively evaluated before and 1-month post-BS, with AS assessed by pulse-wave velocity (PWV), augmentation index (AIx@75) and pulse pressure (PP). Ambulatory 24 h blood pressure (BP), anthropometric data, renin-angiotensin-aldosterone system (RAAS) components and several adipokines and inflammatory markers were also analyzed. Overall reduction in body weight was mean (interquartile range (IQR)) = 11.0% (9.6-13.1). A decrease in PWV, AIx@75 and PP was observed 1-month post-BS (all, p < 0.01). There were also significant Δ in BP, RAAS components, adipokines and inflammatory biomarkers. Multiple linear regression adjusted models showed that Δaldosterone was an independent variable (B coeff.95%CI) for final PWV (B = -0.003, -0.005 to 0.000; p = 0.022). Angiotensin-converting enzyme (ACE)/ACE2 and ACE were independent variables for final AIx@75 (B = 0.036, 0.005 to 0.066; p = 0.024) and PP (B = 0.010, 0.003 to 0.017; p = 0.01), respectively. There was no correlation between ΔAS and anthropometric changes nor with Δ of adipokines or inflammatory markers except high-sensitivity C-reactive protein (hs-CRP). Patients with PWV below median decreased PWV (mean, 95%CI = -0.18, -0.25 to -0.10; p < 0.001) and both AIx@75 and PP at 1-month, but not those with PWV above median. In conclusion, there is an improvement in AS 1-month post-BS that correlates with ΔBP and Δrenin-angiotensin-aldosterone components. The benefit is reduced in those with higher PWV.

ABSTRACT

The COVID-19 pandemic has led to frequent referrals to the emergency department on suspicion of this infection in maintenance hemodialysis (MHD) and kidney transplant (KT) patients. We aimed to describe their clinical features comparing confirmed and suspected non-confirmed COVID-19 cases during the Spanish epidemic peak. Confirmed COVID-19 ((+)COVID-19) corresponds to patient with positive RT-PCR SARS-CoV-2 assay. Non-confirmed COVID-19 ((-)COVID-19) corresponds to patients with negative RT-PCR. COVID-19 was suspected in 61 patients (40/803 KT (4.9%), 21/220 MHD (9.5%)). Prevalence of (+)COVID-19 was 3.2% in KT and 3.6% in MHD patients. Thirty-four (26 KT and 8 MHD) were (+)COVID-19 and 27 (14 KT and 13 MHD) (-)COVID-19. In comparison with (-)COVID-19 patients, (+)COVID-19 showed higher frequency of typical viral symptoms (cough, dyspnea, asthenia and myalgias), pneumonia (88.2% vs. 14.3%) and LDH and CRP while lower phosphate levels, need of hospital admission (100% vs. 63%), use of non-invasive mechanical ventilation (36% vs. 11%) and mortality (38% vs. 0%) (p < 0.001). Time from symptoms onset to admission was longer in patients who finally died than in survivors (8.5 vs. 3.8, p = 0.007). In KT and MHD patients, (+)COVID-19 shows more clinical severity than suspected non-confirmed cases. Prompt RT-PCR is mandatory to confirm COVID-19 diagnosis.

ABSTRACT

INTRODUCCIÓN: La hipertensión arterial resistente (HTAR) supone un importante problema de salud de manejo complejo. Este trabajo evalúa los riesgos y beneficios de añadir espironolactona para tratar la HTAR. MATERIAL Y MÉTODOS: Se evaluaron 216 pacientes con HTAR a quienes se añadió espironolactona (12,5-25 mg/día) como antihipertensivo. Ciento veinticinco se analizaron retrospectivamente y 91 prospectivamente. Se analizaron parámetros de presión arterial (PA) y laboratorio (creatinina plasmática [Creap], filtrado glomerular [FGe] y potasio plasmático [Kp]) al momento basal y tras 3-6-12 meses con espironolactona. RESULTADOS: Se objetivó una variación de PA sistólica/diastólica (media± desviación estándar) de -10,9 ± 2,7/-4,3 ± 1,6 mmHg a los 3 meses y -13,6 ± 2,8/-6,0 ± 1,6 mmHg a los 12 meses; p < 0,001. Valores confirmados mediante monitorización ambulatoria de PA a los 12 meses. A los 3 meses, la Creap incrementó 0,10 ± 0,04mg/dl, el FGe disminuyó -5,4 ± 1,9 ml/min/1,73 m2 y el Kp incrementó 0,3 ± 0,1 mmol/l; p < 0,001 para todos los casos. Estas variaciones se mantuvieron a los 12 meses. No hubo diferencias significativas en las variaciones de PA, Creap, FGe y Kp entre los 3 y 12 meses. Los resultados al analizar las cohortes retrospectiva y prospectiva por separado fueron superponibles. En la cohorte prospectiva, espironolactona fue suspendida en 9 pacientes (9,9%) por efectos adversos. CONCLUSIONES: Tras 3 meses con espironolactona se observó un descenso de PA asociado a descenso del FGe y aumento de Creap y Kp, cambios que se mantuvieron a los 12 meses. Espironolactona es un tratamiento eficaz y seguro para la HTAR en pacientes con FGe basal ≥ 30 ml/min/1,73 m2


INTRODUCTION: Resistant hypertension (RH) is a significant health problem with complex management. The aim of this study was to evaluate the risks and benefits of adding spironolactone to treat RH. MATERIAL AND METHODS: In total, 216 patients with RH in whom spironolactone (12.5-25 mg daily) was added as an antihypertensive were evaluated. One-hundred and twenty-five (125) were analysed retrospectively and 91 prospectively. Blood pressure (BP) and laboratory parameters (serum creatinine [sCrea], estimated glomerular filtration rate [eGFR] and serum potassium [sK]) were analysed at baseline and at 3-6-12 months after introducing spironolactone. RESULTS: A change of systolic/diastolic BP (mean ± standard deviation) of -10.9 ± 2.7/-4.3 ± 1.6 mmHg at 3 months and -13.6 ± 2.8/-6.0 ± 1.6 mmHg at 12 months; p < 0.001 was observed. These values were confirmed with ambulatory-BP monitoring at 12 months. At 3 months, an increase in sCrea of 0.10 ± 0.04 mg/dl, a decrease in eGFR of -5.4 ± 1.9 ml/min/1.73m2 and an increase in sK of 0.3 ± 0.1 mmol/l; p < 0.001 was observed for all cases. These changes were maintained after 12 months. There were no significant differences in changes of BP, sCrea, eGFR and sK between 3 and 12 months. Results of the retrospective and prospective cohorts separately were superimposable. In the prospective cohort, spironolactone was withdrawn in 9 patients (9.9%) because of adverse effects. CONCLUSIONS: After 3 months with spironolactone, a decrease in BP associated with a decrease in the eGFR and an increase in sCrea and sK was observed. These changes were maintained at 12 months. Spironolactone is an effective and safe treatment for RH in patients with baseline eGFR ≥ 30 ml/min/1.73 m2

ABSTRACT

La obesidad está asociada con la hipertensión arterial por mecanismos diversos. La presión arterial (PA) central parece estar más correlacionada que la PA periférica con el riesgo cardiovascular futuro. La cirugía bariátrica constituye un método eficaz para disminuir la PA paralelamente a una pérdida de peso significativa en pacientes con obesidad severa. El estudio de la relación entre la modificación de peso tras cirugía bariátrica y la medición ambulatoria de PA, no solo a nivel periférico, sino también a nivel central, podría aportar información respecto a los mecanismos del daño orgánico asociado a la PA elevada en la obesidad. En esta revisión analizamos la evidencia disponible respecto a la asociación entre la PA central con la obesidad y sus modificaciones tras la cirugía bariátrica


Various mechanisms are related to arterial hypertension in obesity. Central blood pressure (BP) seems to correlate more than peripheral BP with future cardiovascular risk. Bariatric surgery is an effective method to reduce BP along with weight loss in patients with morbid obesity. The study of the relationship between weight modification after bariatric surgery and ambulatory BP measurement, not only peripheral BP, but also central BP, could provide information regarding the mechanisms of organic damage associated with elevated BP in obesity. In this review we analyze the available evidence regarding the association between central BP with obesity and its modifications after bariatric surgery

One-hundred and twenty-five (125) were analysed retrospectively and 91 prospectively. Blood pressure (BP) and laboratory parameters (serum creatinine [sCrea], estimated glomerular filtration rate [eGFR] and serum potassium [sK]) were analysed at baseline and at 3-6-12 months after introducing spironolactone. RESULTS: A change of systolic/diastolic BP (mean±standard deviation) of -10.9±2.7/-4.3±1.6mmHg at 3 months and -13.6±2.8/-6.0±1.6mmHg at 12 months; p<0.001 was observed. These values were confirmed with ambulatory-BP monitoring at 12 months. At 3 months, an increase in sCrea of 0.10±0.04mg/dl, a decrease in eGFR of -5.4±1.9ml/min/1.73m2 and an increase in sK of 0.3±0.1mmol/l; p<0.001 was observed for all cases. These changes were maintained after 12 months. There were no significant differences in changes of BP, sCrea, eGFR and sK between 3 and 12 months. Results of the retrospective and prospective cohorts separately were superimposable. In the prospective cohort, spironolactone was withdrawn in 9 patients (9.9%) because of adverse effects. CONCLUSIONS: After 3 months with spironolactone, a decrease in BP associated with a decrease in the eGFR and an increase in sCrea and sK was observed. These changes were maintained at 12 months. Spironolactone is an effective and safe treatment for RH in patients with baseline eGFR ≥30ml/min/1.73m2.
