Síndrome nefrótico secundario a preeclampsia: presentación, manejo y evolución clínica observados en 5 años de experiencia / Nephrotic syndrome due to preeclampsia: Presentation, management and clinical evolution observed in 5 years experience

Introducción: El síndrome nefrótico (SN) es una entidad rara durante el embarazo. En esta etapa, la preeclampsia (PE) severa es la principal causa. Nuestro objetivo fue describir la presentación clínica, las características analíticas, el manejo médico y la evolución de mujeres con SN por PE. Materiales y métodos: Estudio descriptivo, retrospectivo, realizado entre el 1 de enero de 2017 y el 1 de enero de 2022 (5años). Incluyó mujeres con embarazo ≥20semanas de edad gestacional (EG), internadas por trastorno hipertensivo del embarazo (THE), sin evidencia de daño renal previo a la gestación. Resultados: Entre 652 THE se identificaron 452 PE y 21 SN. La edad materna fue de 25±5,7 años, y la EG al diagnóstico, de 33,1±5,1 semanas. Todas presentaron edema facial y periféricos: 5 derrame pleural, 3 derrame pericárdico y 2 anasarca. La P24 fue de 6,17±2,34g (3,10-10,8), la albúmina sérica de 2,5±0,27g/dl (2,10-2,90) y el colesterol sérico de 281,4±21,7mg/dl (251-316). Hubo 13 que desarrollaron complicaciones maternas: daño renal agudo, edema pulmonar, miocardiopatía dilatada, eclampsia y síndrome HELLP. Todas permanecieron hipertensas en el posparto, requiriendo combinación de dos a tres fármacos antihipertensivos. En el posparto todas recibieron estatinas e inhibidores de la enzima convertidora de angiotensina (IECA) para el manejo de la proteinuria; ninguna desarrolló hiperkalemia o elevaciones de creatinina. La estancia hospitalaria fue de 10,4±3,7 días. Todas revirtieron los parámetros proteinúricos de rango nefrótico antes del alta. No se registraron muertes. Conclusión: La presentación incluyó desde edemas periféricos hasta compromiso seroso. La severidad de la proteinuria fue variable. El uso de IECA no precipitó hiperkalemia ni fallo renal. Las complicaciones maternas fueron frecuentes, pero no se observaron óbitos. (AU)

Introduction: Nephrotic syndrome (NS) is rare during pregnancy. The main cause is severe pre-eclampsia (PR). Our aim was to describe the clinical presentation, analytical features, medical management, and progress of women with NS due to PE. Materials and methods: A descriptive, retrospective study, conducted from 01/01/2017 to 01/01/2022 (5years). Women with a gestational age (GA) ≥20weeks were included in the study, hospitalised due to hypertensive disorders in pregnancy (HDP), with no evidence of kidney damage prior to gestation. Results: Of the 652 HDP, 452 PE and 21 NS were identified. Maternal age was 25±5.7 years, GA at diagnosis was 33.1±5.1 weeks. All the women had facial and peripheral oedema: 5 pleural effusion, 3 pericardial effusion, and 2 anasarca. Their p24 was 6.17±2.34grams (3.10-10.8), serum albumin 2.5±0.27g/dL (2.10-2.90), and serum cholesterol 281.4±21.7mg/dL (251-316). Thirteen developed maternal complications: acute kidney damage, pulmonary oedema, dilated cardiomyopathy, eclampsia, and HELLP syndrome. They all remained hypertensive postpartum, and required a combination of two to three antihypertensive drugs. They all received statins postpartum, and angiotensin converting enzyme (ACE) inhibitors to manage proteinuria. None developed hyperkalaemia or creatinine elevation. Hospital stay was 10.4±3.7days. All nephrotic range proteinuria parameters reversed prior to discharge. No deaths were recorded. Conclusion: Presentation ranged from peripheral oedema to serous involvement. Severity of proteinuria varied. Use of ACE inhibitors did not precipitate hyperkalaemia or kidney failure. Maternal complications were frequent, but no deaths were recorded. (AU)

Niveles plasmáticos de troponina T y de la fracción aminoterminal del propéptido natriurético cerebral y su relación con mortalidad en COVID-19 / Troponin-T and n-terminal pro-brain type natriuretic peptide plasma levels and its relationship with mortality in COVID-19

Introducción: El compromiso cardiovascular en la enfermedad por coronavirus 2019 (COVID-19) no necesariamente se presenta con los síntomas clásicos descriptos en la miocarditis. Es creciente la evidencia que demuestra compromiso cardiovascular subclínico en contexto de la intensa inflamación desatada, la tormenta de citocinas involucradas, el estado protrombótico basal y la disfunción endotelial consecuente. Nos propusimos analizar si la troponina T (TT) y la fracción amino-terminal del propéptido natriurético cerebral (NT-proBNP) determinada al momento de ingreso hospitalario se relacionan con la mortalidad durante la internación de estos pacientes. Material y métodos: Estudio analítico, observacional, de cohortes retrospectivas y corte transversal. Incluyó sujetos con COVID-19 internados por enfermedad moderada-severa, del 20 de marzo de 2020 al 15 de noviembre de 2020. Se analizaron las determinaciones de TT y NT-proBNP obtenidas en las primeras 24 horas de ingreso. Se consideró TT alterada si ≥ 0,014 ng/dL y NT-proBNP alterado si ≥ 300 pg/mL. Resultados: Se incluyeron 108 sujetos, 63,2% hombres, edad 51,5 años (59-43). El 28% ingreso a Unidad de Cuidados Intensivos (UCI) y el 25% falleció. El grupo de pacientes con TT elevada presentó mayor mortalidad (OR = 3,1; IC 95% = 1,10-8,85; p = 0,028) al igual que el grupo con NT-proBNP elevado (OR = 3,47; IC 95% = 1,21-9,97; p = 0,017). Al análisis multivariado sólo NT-proBNP ≥300 pg/mL se mantuvo como factor de riesgo independiente. Conclusiones: Niveles de NT-proBNP ≥ 300 pg/mL al ingreso en pacientes con COVID-19 moderada-severa se relacionaron con una mayor mortalidad.(AU)

Introduction: Cardiovascular compromise in coronavirus disease 2019 (COVID-19) does not necessarily present with the classic symptoms described in myocarditis. There is growing evidence demonstrating subclinical cardiovascular compromise in the context of the intense inflammation unleashed, the cytokine storm involved, the baseline prothrombotic state, and the consequent endothelial dysfunction. We set out to analyse whether Troponin-T (TT) and the amino-terminal fraction of pro-brain natriuretic peptide (NT-proBNP) determined at hospital admission, are related to mortality during the hospitalization of these patients. Material and methods: Analytical, observational, retrospective cohort and cross-sectional study. It included subjects with COVID-19 hospitalized for moderate-severe illness, from 20/03/20 to 15/11/20. The TT and NT-proBNP obtained in the first 24 hours from admission were analysed. Altered TT was considered if ≥.014 ng/dl and altered NT-proBNP if ≥300 pg/ml. Results: One hundred and eight subjects were included, 63.2% men, age 51.5 years (59-43), 28% were admitted to the Critical Unit and 25% died. The group with elevated TT presented higher mortality (OR = 3.1; 95%CI = 1.10-8.85; p = .02). The group with elevated NT-proBNP also show higher mortality (OR = 3.47; 95%CI = 1.21-9.97; p = .01). On multivariate analysis, only NT-proBNP ≥300 pg/ml remained an independent risk factor. Conclusions: NT-proBNP levels ≥300 pg/ml at admission in patients with moderate-severe COVID-19 were associated with higher mortality.(AU)
