RESUMO

Hypertension is a common finding in patients with chronic kidney disease (CKD) and it is associated with kidney disease progression. Hypertensive nephropathy is a diagnosis, mostly based on clinical suspicion and defines many cases of CKD of unknown etiology. The risk of progression of hypertension-attributed nephropathy seems to have a genetic background as has been demonstrated in African-American patients with APOL1 gene risk variants.

RESUMO

During the past two years we have witness a tremendous worldwide health crisis imposed by the coronavirus disease (COVID-19). This situation led to the urgent development and implementation of vaccines in an attempt to decrease not only the SARS-CoV-2 transmissibility but also the severe forms of COVID-19. Although these vaccines were approved based on an adequate benefit-risk ratio, at the moment of their implementation in 2021 we did not have sub-studies in special populations; patients with systemic lupus erythematosus (SLE) among them. We describe two cases of lupus nephritis flare following the immunization against SARS-CoV-2 with the first component of Sputnik V and Sinopharm. Both patients were in complete remission on maintenance therapy with mycophenolate and without glucocorticoids. The flare presented with an increased protein/creatinine ratio in urine and positive anti-DNA antibodies without other relevant accompanying findings. After treatment with prednisone (20 y 10 mg/day in case 1 and 2, respectively) and an increased dose of mycophenolate (from 1.5 g/day to 2.0 g/dayand 1.08 to 1.44 g/día of sodic mycophenolate in case 1 y 2, respectively) both patients regained renal remission. These cases are of relevance as they introduce a possible association between the different anti-SARS-CoV-2 vaccine platforms and SLE flares; at the same time to suggest the need for close control in the post vaccination period in this population of patients.


Debido el alto impacto sanitario que causó el nuevo coronavirus SARS-CoV-2, se procedió al rápido desarrollo e implementación de vacunas en un intento de disminuir su transmisibilidad y las formas graves de la COVID 19. La aprobación de estas vacunas se basó en una adecuada relación riesgo/beneficio, sin embargo, en el año 2021 no disponíamos de sub-estudios en poblaciones especiales; entre ellas, pacientes con lupus eritematoso sistémico (LES). Presentamos dos casos de brote de glomerulonefritis lúpica luego de la inmunización contra SARS-CoV-2 dado por el primer componente de Sputnik V y Sinopharm. Ambas pacientes se encontraban en remisión completa con tratamiento de mantenimiento en dosis estables de micofenolato y libre de glucocorticoides. El brote de glomerulonefritis se presentó con aumento de relación proteinuria/creatininuria y anticuerpos anti ADN positivos sin otros hallazgos acompañantes de relevancia. En ambas pacientes se reinició prednisona (20 y 10 mg/día en caso 1 y 2, respectivamente) y se aumentó la dosis de micofenolato (de 1.5 g/día a 2.0 g/día y de 1.08 a 1.44 g/día de micofenolato sódico en caso 1 y 2, respectivamente) con remisión completa del cuadro. Estos casos son de relevancia ya que introducen una posible asociación entre las diferentes plataformas vacunales anti SARS-CoV-2 y reactivación del LES, a la vez de sugerir la necesidad de un control estrecho en el período post-vacunal en esta población de pacientes.

RESUMO

Arterial hypertension is a highly prevalent disease and its secondary causes must always be kept in mind because the treatment and prognosis differ between these and essential hypertension. Here we present the first reported case in Argentina of a 21-year-old patient with arterial hypertension and hypokalaemia due to a renin-secreting juxtaglomerular cell tumour, which was diagnosed after seven years of development.

RESUMO

La hipertensión arterial es una enfermedad de alta prevalencia y siempre deben tenerse en cuenta las causas secundarias que pueden originarla, debido a que el tratamiento y el pronóstico difieren entre estas y la hipertensión esencial. Presentamos el primer caso reportado en Argentina de una paciente de 21 años con hipertensión arterial e hipopotasemia, debido a un tumor de células yuxtaglomerulares productor de renina, el cual fue diagnosticado tras siete años de evolución (AU)
