The hidden diabetic kidney disease in a university hospital-based population: a real-world data analysis.

Background: Correct identification of diabetic kidney disease (DKD) in type 2 diabetes mellitus (T2DM) patients is crucial to implement therapeutic interventions that may prevent disease progression. Methods: We compared the real prevalence of DKD in T2DM patients according to actual serum and urine laboratory data with the presence of the diagnostic terms DKD and/or CKD on the electronic medical records (EMRs) using a natural language processing tool (SAVANA Manager). All patients ˃18 years of age and diagnosed with T2DM were selected. DKD was defined as an estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2 or a urinary albumin:creatinine ratio (UACR) >30 mg/g or a urinary protein:creatinine ratio (UPCR) >0.3 g/g after excluding acute kidney injury. Results: A total of 15 304 T2DM patients identified on EMRs were eligible to enter the study. A total of 4526 (29.6%) T2DM patients had DKD according to lab criteria. However, the terms CKD or DKD were only present in 33.1% and 7.5%, representing a hidden prevalence of CKD and DKD of 66.9% and 92.5%, respectively. Less severe kidney disease (lower UACR or UPCR, higher eGFR values), female sex and lack of insulin prescription were associated with the absence of DKD or CKD terms in the EMRs (P < .001). Conclusions: The prevalence of DKD among T2DM patients defined by lab data is significantly higher than that reported on hospital EMRs. This could imply underdiagnosis of DKD, especially in patients with the least severe disease who may benefit the most from optimized therapy.

Fracaso renal agudo en pacientes hospitalizados por COVID-19 / Acute kidney failure in patients admitted due to COVID-19

ANTECEDENTES Y OBJETIVO: En diciembre de 2019 surgió en Wuhan, China, la COVID-19, causada por el virus SARS-CoV-2 y declarada pandemia global por la Organización Mundial de la Salud en marzo de 2020. Es una infección respiratoria con complicaciones a nivel cardiaco, hematológico, digestivo, neurológico y renal. El fracaso renal agudo (FRA) en pacientes hospitalizados por COVID-19 se presenta en el 0,5-25% y es un factor de mal pronóstico. Los mecanismos de afectación renal no están completamente aclarados. Presentamos la evolución clínica de pacientes ingresados por COVID-19 con FRA que requirieron atención por Nefrología en un hospital terciario de la Comunidad de Madrid, España. MÉTODOS: Este es un estudio observacional prospectivo de todos los casos que ingresaron por COVID-19 entre el 6 de marzo y el 12 de mayo de 2020 y requirieron atención por Nefrología. Se recogieron datos clínicos y analíticos de características basales, y la evolución de la COVID-19 y del FRA. RESULTADOS: Se analizaron 41 pacientes con una edad media de 66,8 años (DE 2,1), el 90,2% varones, y con enfermedad renal crónica previa en el 36,6%. El 56,1% presentaron neumonía grave o síndrome de distrés respiratorio agudo y el 31,7% requirió ingreso en UCI. El FRA fue de etiología prerrenal en el 61%, necrosis tubular aguda en contexto de sepsis en el 24,4%, glomerular en el 7,3% y por toxicidad tubular en el 7,3%. Se registró proteinuria en el 88,9% y hematuria en el 79,4%. El 48,8% de los pacientes requirió terapia de sustitución renal. La mediana de estancia fue de 12 días (RIC 9-23), y el 22% fallecieron. Los pacientes que desarrollaron FRA durante el ingreso presentaron valores más altos de proteína C reactiva, LDH y dímero-D, una afectación pulmonar más grave, más necesidad de ingreso en UCI, más tratamiento con lopinavir/ritonavir y fármacos biológicos, y mayor necesidad de terapia de sustitución renal. CONCLUSIONES: La hipovolemia y la deshidratación son una causa frecuente de FRA en pacientes con COVID-19. Aquellos que desarrollan FRA intrahospitalario presentan un perfil de peor pronóstico respiratorio, analítico y renal. Creemos que la monitorización de marcadores renales, así como el manejo individualizado de la volemia, pueden ser determinantes para prevenir el FRA

BACKGROUND AND AIM: In December 2019, a coronavirus 2019 (COVID-19) outbreak, caused by SARS-CoV-2, took place in Wuhan, China, and was declared a global pandemic in March 2020 by the World Health Organization. It is a prominently respiratory infection, with potential cardiological, hematological, gastrointestinal and renal complications. Acute kidney injury (AKI) is found in 0.5-25% of hospitalized COVID-19 patients and constitutes a negative prognostic factor. Renal damage mechanisms are not completely clear. We report the clinical evolution of hospitalized COVID-19 patients who presented with AKI requiring attention from the Nephrology team in a tertiary hospital in Madrid, Spain. METHODS: This is an observational prospective study including all COVID-19 cases that required hospitalization and Nephrology management from March 6th to May 12th 2020. We collected clinical and analytical data of baseline characteristics, COVID-19 and AKI evolutions. RESULTS: We analyzed 41 patients with a mean age of 66.8 years (SD 2.1), 90.2% males, and with a history of chronic kidney disease in 36.6%. A percentage of 56.1 presented with severe pneumonia or acute respiratory distress syndrome, and 31.7% required intensive care. AKI etiology was prerenal in 61%, acute tubular necrosis in the context of sepsis in 24.4%, glomerular in 7.3% and tubular toxicity in 7.3% of the cases. We reported proteinuria in 88.9% and hematuria in 79.4% of patients. A percentage of 48.8 required renal replacement therapy. Median length of stay was 12 days (IQR 9-23) and 22% of the population died. Patients who developed AKI during hospital stay presented with higher C-reactive protein, LDH and D-dimer values, more severe pulmonary damage, more frequent ICU admission, treatment with lopinavir/ritonavir and biological drugs and renal replacement therapy requirement. CONCLUSIONS: Hypovolemia and dehydration are a frequent cause of AKI among COVID-19 patients. Those who develop AKI during hospitalization display worse prognostic factors in terms of pulmonary damage, renal damage, and analytical findings. We believe that monitorization of renal markers, as well as individualized fluid management, can play a key role in AKI prevention

Median length of stay was 12 days (interquartilic range 9-23) and 22% of the population died. Patients who developed AKI during hospital stay presented with higher C-reactive protein, Lactate dehydrogenase-LDH and d-dimer values, more severe pulmonary damage, more frequent intensive care unit-ICU admission, treatment with lopinavir/ritonavir and biological drugs and RRT requirement. CONCLUSIONS: Hypovolemia and dehydration are a frequent cause of AKI among COVID-19 patients. Those who develop AKI during hospitalization display worse prognostic factors in terms of pulmonary damage, renal damage, and analytical findings.

Epidemiology of the colonization and acquisition of methicillin-resistant staphylococci and vancomycin-resistant enterococci in dogs hospitalized in a clinic veterinary hospital in Spain.

Antibiotic resistance is one of the biggest threats to human and animal health. Methicillin-resistant Staphylococcus spp. (MRS) and vancomycin-resistant Enterococcus spp. (VRE) are of increasing importance in hospital and/or nosocomial infections and represent a potential risk of transmission to humans from infected or colonized companion animals. Studies on the risk factors associated with colonization by multiresistant bacteria in animals are scarce. The present study aimed to estimate the prevalence and incidence of MRS and VRE in canine patients hospitalized in a veterinary hospital and to identify the risk factors for its acquisition and persistence. Nasal and perianal swabs were obtained from 72 dogs. Antimicrobial susceptibility assays and molecular detection of mecA and van genes were performed. A prevalence of 13.9% and incidence of 26.5% was observed in dogs colonized by MRS at hospital admission and release, respectively, higher values than those described in most veterinary studies. Thirty-five Staphylococcus isolates had mecA gene and showed higher resistance levels to most of the antimicrobials evaluated. Previous and concomitant use of antibiotics and corticosteroids has been associated with an increase in MRS colonization. The use of antibiotics in other animals living with the canine patients has also been identified as an associated factor, suggesting cross transmission. The presence of van-resistant genes from Enterococcus spp. was not detected. Pets should be considered possible vehicles of transmission and reservoirs for MRS bacteria and veterinary hospitals should be considered high-risk environments for the occurrence and spread of nosocomial infections and resistant bacteria.
