RESUMO

RESUMEN Introducción:La insuficiencia renal agudaes una complicación descripta en pacientes con infección por SARS-CoV-2que ronda 0,5-7% de los casos. Objetivo: evaluar el valor pronóstico del compromiso renal en los pacientes internados por enfermedad por COVID-19. Material y métodos:Se analizó una cohorte prospectiva de pacientes mayores de 18 años con diagnóstico de enfermedad por COVID-19 en el período comprendido entre los meses demayo a octubre de 2020.Todos fueron seguidos hasta el alta hospitalaria o muerte. Se evaluaron parámetros clínicos, laboratorio, score de Charlson, mortalidad y gravedad de enfermedad COVID-19. Resultados:Ingresaron 412 pacientes al estudio, 57% hombres y con promedio de edad de 51 ±16 años. El 20% tenía un score de Charlson≥3, la incidencia de insuficiencia renal aguda, definida como el aumento de la creatinina sérica 0,3 mg/dl del valor basal, fue 5,5% (n=23) yla mortalidad hospitalaria de2,2% (n=9). El análisis bi y multivariado mostró que el sexo masculino[OR= 0,32(IC0,12-0,82), p=0,017], dímero D>500ng/ml[OR= 3,68(IC 1,23-10,96), p=0,019], relación proteinuria/creatininuria >0,20[OR=2,43 (IC 1,03-5,74), p=0,043],insuficiencia renal aguda[OR=10,53 (IC 2,99-37,09), p0,0001]fueron predictores de COVID-19 grave, definido como frecuencia respiratoria 30 x min, saturación de oxígeno <93% o PO2/FIO2300.En el análisis bivariado la mortalidad se asoció con el desarrollo de COVID-19graveOR= 68.76 (IC 8,39-563,36), p0,0001 e insuficiencia renal agudaOR= 45,41 (IC 10,45-197,22), p0,0001. Conclusión:El compromiso renal está asociado a peor evolución y mayor mortalidad en COVID-19. La valoración de la función renal y la proteinuria son parámetros accesibles que deberían ser incluidos como factores de riesgo en la evaluación inicial.


ABSTRACT Introduction:Acute kidney injuryis a complication described in patients with SARS-CoV-2 infection that is around 0.5-7% of cases. Objective:evaluate the prognostic value of kidney involvement in patients hospitalized for COVID-19 disease. Methods:A prospective cohort of patients over 18 years with a diagnosis of COVID-19 disease in the period from May to October 2020 was analyzed. All were followed up until hospital discharge or death.Clinical and biochemicalparameters, Charlson score, mortality and severity of COVID-19 disease were evaluated. Results:Four hundred twelve patients entered the study, 57% men and mean age 51 ± 16 years. Twenty percent had a Charlson score ≥3, the incidence of acute kidney injury, defined as the increase in serum creatinine 0.3 mg / dl from baseline, was 5.5% (n = 23) and hospital mortality was 2.2% (n = 9). The bivariate and multivariate analysis showed that the male sex [OR= 0.32 (IC 0.12-0.82), p =0.017], D-dimer> 500 ng/ml [OR= 3.68 (IC 1.23-10.96), p = 0.019], urinary protein/creatinine> 0.20 [OR= 2.43 (CI 1.03-5.74), p = 0.043], and AKI [OR= 10.53 (CI 2.99-37.09), p <0.0001] were predictors of severe COVID-19, defined as respiratory rate>30 x min, oxygen saturation <93% or PO2/FIO2300. The univariate analysis of mortality was associated with the development of severe COVID-19 [OR= 68.76 (CI 8.39-563.36), p <0.0001 and acute kidney injury OR= 45.41 (CI 10.45-197.22), p 0.0001. Conclusion:Renal involvement is associated with worse evolution and higher mortality in COVID-19. The assessment of renal function and proteinuria are accessible parameters that should be included as risk factors in the initial evaluation of these patients.

RESUMO

RESUMEN Introducción: La bacteriuria asintomática (BA), en el primer año postrasplante renal,tiene una incidencia mayor al 50%. La infección urinaria (ITU) es la complicación infecciosa más común en trasplante renal, su incidencia oscila entre el 30 y el 70% en el primer año.Objetivo:Analizar la incidencia de ITU y BA en el primer año postrasplante renal y su impacto en la función renal. Material y métodos: Estudio retrospectivo, de pacientes trasplantados renales, mayores de 18 años, en el período comprendido entre enero de 2006 y diciembre de 2017, en nuestro centro. Fueron excluidos pacientes con trasplantes renales combinados, pérdida del injerto renal durante el primer año por complicaciones quirúrgicas (trombosis, rotura renal) o médicas (rechazo, recidiva de enfermedad de base).Resultados: Fueron analizados 161 pacientes adultos trasplantados renales. La incidencia en el primer año postrasplante de ITU y BA fue del 32% y del 25%, respectivamente. La función renal promedio al año del trasplante fue: de los pacientes con ITU(n=53) Cr 1,36(±0,44), de los pacientes con BA no tratada(n=30) Cr 1.36(±0,41), de los pacientes con BA tratada(n=11)Cr 1,39(±0,42), y de los pacientes sin ITU ni BA(n=90) Cr 1,31(±0,43) p=0,95. El riesgo de ITU en las BA no tratadas fue del 55% y en las tratadas del 57%, con un RR 0,96 (IC 95% 0,52-1,8). Conclusión: No hubo diferencias significativas en la función renal al año del trasplante en los pacientes que tuvieron ITU y BA en relación a los pacientes que no tuvieron. El tratamiento de las BA no redujo el riesgo de padecer ITU.


ABSTRACT Introduction:Asymptomatic bacteriuria (AB) during the first year post-renal transplantation has an incidence higher than 50%. Urinary tract infection (UTI) is the most frequent complication of renal transplantation; its incidence is between 30 and 70 % during the first year. Objective: To analyze the incidence of UTI and AB during the first year post-renal transplantation and their impact on renal function. Methods: Retrospective study in renal transplantation patients older than 18 between January 2006 and December 2017 in our center. Patients who had received combined renal transplantation, lost renal graft during the first year due to surgical complications (thrombosis, allograft rupture) or medical complications (rejection, underlying disease recurrence) were excluded. Results: A study was performed with 161 adult patients who had undergone kidney transplantation. The incidence of UTI and AB during the first year after receiving transplantation was 32% and 25%, respectively. The mean renal function one year after transplantation was as follows: (n=53) Cr 1.36(±0.44) for UTI patients; (n=30) Cr 1.36(±0.41) for AB non-treated patients; (n=11) Cr 1.39(±0.42) for AB treated patients, and (n=90) Cr 1.31(±0.43) p=0.95 for patients not suffering from UTI or AB. The risk of UTI was 55 % for non-treated AB and 57% for treated AB, with RR 0.96 (95% CI: 0.52-1.8).Conclusion: No significant differences in renal function were found in UTI and AB patients one year after transplantation as compared to patients not suffering from these conditions. AB treatment did not reduce UTI risk.

RESUMO

BACKGROUND AND AIMS: Surveillance during liver transplantation (LT) waiting list has scarcely been reported in South America. We aimed to describe hepatocellular carcinoma (HCC) surveillance during the LT waiting list in the daily practice. PATIENTS AND METHODS: A multicenter retrospective analysis in cirrhotic patients was carried out. All patients underwent an ultrasound (US) every 6 months and the last pre-LT US was compared with explanted liver findings. A false-negative case was considered when incidentally found HCC (iHCC) was detected, whereas a false-positive case was considered when HCC diagnosed before LT (cHCC) was not confirmed in the explanted liver. US performance was assessed after excluding cHCC patients referred to transplant evaluation. RESULTS: Of 643 patients, 129 had HCC, of whom 92 had cHCC (71.3%) and 37 had iHCC (28.7%). Five patients (5.4%) had nonconfirmed cHCC (n=3 regenerative nodules, n=1 biliary hamartoma, and n=1 cholangiocarcinoma). Patients with iHCC had a higher MELD score (23±10 vs. 15±10; P<0.0001), and were more frequently Child-Pugh C (62.2 vs. 36.6%; P=0.006) compared with patients with cHCC. The number of US performed during waiting list was 1.7±1.6 (median 1.0). During transplant waiting list, the sensitivity and specificity of US were 33 and 99%, with positive and negative predictive values of 0.89 and 0.93, respectively. Multivariate analysis showed that the strongest variable related to iHCC finding was pre-LT Child-Pugh C status (OR 3.5; P=0.004). CONCLUSION: Screening for liver cancer remains an important issue during transplant waiting list. However, the US screening method should be reviewed particularly for Child-Pugh C patients.
