Early acute kidney injury is associated with in-hospital adverse outcomes in critically ill burn patients: an observational study.

BACKGROUND: There are no studies in large series of burn patients on the relationship between acute kidney injury (AKI) and adverse outcomes using the Kidney Disease: Improving Global Outcomes (KDIGO) guidelines. METHODS: We retrospectively analysed data from a cohort of burn patients admitted to the intensive care unit (ICU) with the diagnosis of burn injury. The diagnosis of AKI over the first 7 days after injury was made according to the KDIGO guidelines. The primary outcome was ICU mortality. We used estimative models using univariable and multivariable logistic regression analyses. RESULTS: A total of 960 patients were studied and AKI was diagnosed in 50.5%. In multivariable analysis, AKI was associated, as compared with patients without AKI, with ICU mortality {adjusted odds ratio [aOR] 2.135 [95% confidence interval (CI) 1.384-3.293]} and secondary outcomes [kidney replacement therapy, aOR 4.030 (95% CI 1.838-8.835); infection, aOR 1.437 (95% CI 1.107-1.866); hospital mortality, aOR 1.652 (95% CI 1.139-2.697)]. AKI stage 1 was associated with a higher ICU [aOR 1.869 (95% CI 1.183-2.954)] and hospital mortality [aOR 1.552 (95% CI 1.050-2.296)] and infection [aOR 1.383 (95% CI 1.049-1.823)]. AKI meeting the urine output (UO) criterion alone was not associated with increased mortality. Ignoring the UO criterion would have missed 50 (10.3%) cases with AKI. CONCLUSION: The KDIGO guidelines are useful to diagnose AKI in burn patients. Even the mild form of AKI is independently associated with increased mortality. Considering the UO criterion is important to more accurately assess the incidence of AKI, but AKI meeting the UO criterion alone is not associated with increased mortality.

Consensus document on autosomal dominant polycystic kindey disease from the Spanish Working Group on Inherited Kindey Diseases. Review 2020.

Autosomal dominant polycystic kidney disease (ADPKD) is the most frequent cause of genetic renal disease and accounts for 6-10% of patients on kidney replacement therapy (KRT). Very few prospective, randomized trials or clinical studies address the diagnosis and management of this relatively frequent disorder. No clinical guidelines are available to date. This is a revised consensus statement from the previous 2014 version, presenting the recommendations of the Spanish Working Group on Inherited Kidney Diseases, which were agreed to following a literature search and discussions. Levels of evidence mostly are C and D according to the Centre for Evidence-Based Medicine (University of Oxford). The recommendations relate to, among other topics, the use of imaging and genetic diagnosis, management of hypertension, pain, cyst infections and bleeding, extra-renal involvement including polycystic liver disease and cranial aneurysms, management of chronic kidney disease (CKD) and KRT and management of children with ADPKD. Recommendations on specific ADPKD therapies are provided as well as the recommendation to assess rapid progression.

Documento de consenso de poliquistosis renal autosómica dominante del grupo de trabajo de enfermedades hereditarias de la Sociedad Española de Nefrología. Revisión 2020 / Consensus document on autosomal dominant polycystic kindey disease from the Spanish Working Group on Inherited Kindey Diseases. Review 2020

La poliquistosis renal autosómica dominante (PQRAD) es la causa más frecuente de nefropatía genética y representa entre el 6 y el 10% de los pacientes en terapia de reemplazo renal (TRR).Muy pocos ensayos prospectivos, aleatorizados o estudios clínicos abordan el diagnóstico y el tratamiento de este trastorno relativamente frecuente. No hay guías clínicas disponibles hasta la fecha. Este es un documento de consenso revisada de la versión anterior del 2014, que presenta las recomendaciones del Grupo de Trabajo Español de Enfermedades Renales Hereditarias, acordadas tras la búsqueda bibliográfica y discusiones. Los niveles de evidencia en su mayoría son C y D según el Centro de Medicina Basada en Evidencia (Universidad de Oxford). Las recomendaciones se relacionan, entre otros temas, con el uso de diagnóstico por imágenes y genético, el manejo de la hipertensión, el dolor, las infecciones y el sangrado quístico, la afectación extrarrenal, incluida la enfermedad poliquística hepática y los aneurismas craneales, el manejo de la enfermedad renal crónica y el TRR, así como el seguimiento de niños con PQRAD. Se proporcionan recomendaciones sobre terapias específicas para la PQRAD, así como la recomendación para evaluar la rápida progresión. (AU)

Ischemic stroke and purpuric dermatitis as COVID-19-related complications in a peritoneal dialysis patient.

Patients on dialysis may have an elevated risk of severe coronavirus disease 2019 (COVID-19) and its complications due to their high prevalence of comorbidities. Here we describe the case of an 80-year-old male undergoing peritoneal dialysis with a moderate SARS-CoV-2 infection who developed a purpuric dermatitis and ischemic stroke after successful recovery from his bilateral pneumonia. Erythemato-papular lesions affecting trunk and lower limbs appeared 17 days after the onset of SARS-CoV-2 symptoms. These kind of lesions are an infrequent cutaneous manifestation of COVID-19. The pathology revealed a moderate purpuric dermatitis affecting superficial dermis and corticoesteroids were prescribed achieving complete resolution. Arterial thrombosis affecting cerebellar vermis emerged 30 days after the onset of COVID-19 symptoms. It occurred 5 days after withdrawal of antithrombotic prophylaxis that the patient received from his admission until 2 weeks after discharge. He completely recovered from his paresis and continued on his regular antiaggregation therapy. This is the first case report published of a patient with PD with such COVID-19-related complications. More experience is needed to determine the appropriate length of antithrombotic prophylaxis especially in high-risk individuals.

Selective Digestive Decontamination Attenuates Organ Dysfunction in Critically Ill Burn Patients.

OBJECTIVE: To evaluate whether selective decontamination of the digestive tract (SDD) attenuates organ dysfunction in critically ill burn patients. BACKGROUND: The effect of SDD on the development and progression of organ dysfunction, as an important determinant of mortality in burned patients, is still unknown. We asked whether organ dysfunction is mitigated by treatment with SDD. METHODS: Patients with burns >20% of total body surface or suspected inhalation injury from a randomized placebo-controlled trial were analyzed to determine the relationship between treatment received (placebo or SDD) and the severity of organ dysfunction as measured by the area under the curve of the Sequential Organ Failure Assessment (SOFA) score (and its individual components) from day 1 to day 7 of admission. RESULTS: One hundred seven patients (53 in the SDD group and 54 in the placebo group) were included. Survival was significantly higher in SDD-treated patients (48 of 53, 90.6%) than in placebo-treated patients (39 of 54, 72.2%, P = 0.013). Total (P < 0.01) and respiratory (P < 0.01), cardiovascular (P = 0.04) and hematological (not reaching statistical significance, P = 0.07) organ dysfunction was associated with mortality after adjusting for predicted mortality. In multivariate logistic regression, SDD treatment was independently associated with total (P < 0.01), respiratory (P = 0.02), and hematological (P < 0.01) dysfunction over the first week postinjury. CONCLUSIONS: The beneficial effect of SDD on mortality in critically ill burned patients is accompanied by a reduction in the degree of organ dysfunction. SDD seems to be a valuable therapeutic strategy to prevent organ dysfunction and, more specifically, respiratory and hematological dysfunction in severely ill burn patients.

Spanish guidelines for the management of autosomal dominant polycystic kidney disease.

Autosomal dominant polycystic kidney disease (ADPKD) is the most frequent cause of genetic renal disease and accounts for 6-10% of patients on renal replacement therapy (RRT). Very few prospective, randomized trials or clinical studies address the diagnosis and management of this relatively frequent disorder. No clinical guidelines are available to date. This is a consensus statement presenting the recommendations of the Spanish Working Group on Inherited Kidney Diseases, which were agreed to following a literature search and discussions. Levels of evidence found were C and D according to the Centre for Evidence-Based Medicine (University of Oxford). The recommendations relate to, among other topics, the use of imaging and genetic diagnosis, management of hypertension, pain, cyst infections and bleeding, extra-renal involvement including polycystic liver disease and cranial aneurysms, management of chronic kidney disease (CKD) and RRT and management of children with ADPKD. Recommendations on specific ADPKD therapies are not provided since no drug has regulatory approval for this indication.

Salvage of accidentally sectioned peritoneal catheter: report of three cases.

Peritoneal dialysis (PD) accounts for 6% of patients on maintenance dialysis. There are several factors responsible for this low prevalence. Transfer of patients to hemodialysis when any problem in the technique is present is probably one of the most frequent reasons. Thus, when a problem in the PD catheter appears they are routinely removed instead of subjecting to salvage procedures. We report three cases of accidental cutting of the peritoneal catheter and present the steps taken to salvage the catheter without discontinuing the technique and avoiding withdrawal of the catheter.

Sudden death after arteriovenous fistula ligation in a renal transplant patient.

After a period of time using an arteriovenous (AV) fistula as vascular access for hemodialysis, kidney transplant recipients usually undertake surgical closure if the fistula is not spontaneously closed. In all prospective studies addressing this issue, absence of major adverse events and progressive decrease in left ventricular volume and mass is the rule. However, in these studies, patients with heart failure New York Heart Association (NYHA) III or IV were not included, and consequently, the effects of AV ligation in these high-risk patients are not well known. We present a heart failure NYHA IV renal transplant patient with fatal evolution after surgical closure of her high-flow AV fistula.
