Introduction: This article describes the main differences between COVID-19-induced acute kidney injury (AKI-COVID19) in patients with previous normal renal function (AKI-NRF) and those with chronic kidney disease (AKI-CKD) treated in a high complexity clinic in Barranquilla (Colombia). Material and Methods: The patients included in this study (n: 572) were those with a positive diagnosis of COVID-19 confirmed by detection of a positive PCR for SARS-CoV-2. Of these patients, 188 developed AKI during their hospital stay. Patients’ epidemiological data, serum parameters, and clinical frailty status were recorded. Statistical analysis and comparison among AKI-NRF, AKI-CKD, and non-AKI patients were performed. Results: The incidence of COVID-19-induced AKI was 33%, with the majority classified as AKIN 1, 16% requiring renal replacement therapy, and AKI-COVID19 mortality of 68%. A significantly higher prevalence of hypertension, cardiac disease, and serum reactive C-protein and lower albumin values in AKI-CKD patients was recorded. Mortality rate, invasive ventilation requirement, and D-dimer levels were significantly higher in AKI-NRF patients: Conclusion: Different clinical patterns between AKI-NRF and AKI-CKD were documented.
A finales del 2019 se inició en Wuhan, China, el brote de un nuevo coronavirus que se dispersó por todo el mundo infectando y cobrando miles de vidas. Se ha encontrado que ciertas comorbilidades constituyen factores de riesgo para resultados poco satisfactorios de la enfermedad, pero es poco lo que se ha descrito sobre pacientes en hemodiálisis, a pesar de tratarse de una población de alto riesgo de infección, complicaciones y muerte.En este artículo se describe el curso clínico, las manifestaciones clínicas y las complicaciones de la COVID-19 en siete pacientes en hemodiálisis permanente y se hacen recomendaciones para el manejo de pacientes con enfermedad renal crónica.
Introduction: Making an early diagnosis of acute kidney injury (AKI) is crucial. Classical biomarkers are not capable of early detection of AKI, but novel biomarkers that do have this capability are expensive and not universally available. This prospective study attempts to mitigate these limitations through the evaluation of daily urine analysis on patient admitted to a critical care unit in order to detect early AKI. Methods: Daily urinary indices were measured on every patient admitted to the intensive care unit (ICU) from the time of admission until his/her discharge from the ICU or death. This renal monitoring consisted of daily blood and spot morning urine samples in order to measure creatinine, urea, sodium, chloride and potassium in order to calculate the fractional excretion of sodium (FENa), chloride, urea and potassium. The data collected on these patients in the previous days was analyzed to determine whether or not there was a significant statistical difference in the urinary indices one day before the clinical diagnosis of AKI (day – 1) and 2 days before the diagnosis (day – 2). The statistical test applied was a single rank test, using as a limit of significance a value of P < 0.05. Results: Of the 203 patients included, 61 developed AKI. A statistical significant difference was documented only in the value of urinary sodium (UNa) and FENa between day-1 (one day before AKI clinical diagnosis) and day-2 (two days before AKI clinical diagnosis). Conclusion: Daily monitoring of UNa and FENa detected a significant change in their basal values 24 hours before clinical diagnosis of AKI was made.
ResumenEl objetivo del presente trabajo fue presentar una serie de casos de COVID-19 con manifestaciones atípicas de la enfermedad. Los casos fueron atendidos por un equipo interdisciplinario de personal de la salud de una clínica de cuarto nivel en Barranquilla, Colombia, y posteriormente los investigadores tomaron los datos de las historias clínicas. Se evaluaron tres casos: el primero tuvo evolución tórpida y coinfección con virus de la influenza H1N1 y los otros dos, manifestaciones gastrointestinales como debut de la enfermedad; todos tuvieron desenlace satisfactorio. La pandemia por SARS-CoV-2 cada día cobra más vidas, por lo que para identificar oportunamente a los infectados y tomar medidas tanto terapéuticas como de prevención y así evitar la propagación de la enfermedad y lograr su control, es necesario realizar reportes de caso en donde se evidencie la diversa variedad de presentaciones de COVID-19.
