The development of COVID-19 associated AKI is closely linked to the severity of the disease course. The main risk factor for kidney failure requiring kidney replacement therapy is the necessity for invasive ventilation, whereby the onset of renal failure is often closely associated with the timing of intubation. Additionally, the risk factors for a severe course of COVID-19 have been shown to also be risk factors for renal failure. AKI in COVID-19 shows a high mortality and in some patients leads to chronic kidney disease; however, full recovery of kidney function in survivors who need dialysis is not uncommon. With respect to prevention and treatment of renal failure associated with COVID-19, the same recommendations as for AKI from other causes are valid (Kidney Disease: Improving Global Outcomes, KDIGO bundles). Due to the large numbers of patients in the setting of overwhelmed resources, the availability of extracorporeal renal replacement procedures can become critical, especially since hypercoagulation is frequent in COVID‑19. In order to avoid triage situations, in some centers acute peritoneal dialysis was used as an alternative to extracorporeal procedures.</p>","PeriodicalId":41844,"journal":{"name":"Nephrologe","volume":"16 1","pages":"20-25"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s11560-020-00471-1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39086868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition to the lungs, SARS-CoV‑2 can invade multiple cell types in other organs, such as the kidneys and replicate there. Important damaging pathways of the virus, such as vascular endotheliitis, thrombotic events and systemic cytokine release are still incompletely understood. Coronavirus disease 2019 (COVID-19) is a systemic disease that necessitates intensive medical care and in particular, internal medicine involvement and represents a major challenge for all disciplines of internal medicine. Among these, nephrology in particular is involved in the fight against COVID-19 in a variety of ways: urine investigations can provide indications of multiple organ involvement, endotheliitis, microthrombi and microcirculation damage, etc. Experience with low serum albumin levels and antithrombin III activity in nephrotic patients helps to point out the decreasing effects of loop diuretics and heparin to other specialist disciplines. Nephrological knowledge of the complications of hypoalbuminemia and \"resistance\" to diuretics must lead to an early implementation of renal replacement procedures in order to be able to prevent mechanical ventilation in COVID-19 intensive care patients with increased extracellular lung fluid. The kidneys can be used as a seismograph for severe courses of COVID-19 and nephrological knowledge can be brought to use to optimize the intensive medical care for critically ill patients.

Patients on dialysis represent a particularly vulnerable group during the SARS-CoV‑2 pandemic. Initial data from international registries show a much higher mortality of dialysis patients with SARS-CoV‑2 infections. Because of the substantial differences between the healthcare systems, (state) preventive measures and treatment possibilities etc., in the different countries worldwide, local and national registry data cannot be easily transferred. In order to gain a reliable overview of the prevalence and mortality of dialysis patients with SARS-CoV‑2 infection in Germany, the German Society of Nephrology implemented a national registry for dialysis patients with a SARS-CoV‑2 infection. Within this framework a standardized collection of these data is carried out on a weekly basis, which should enable a real-time overview of the case numbers and perhaps the acquisition of new scientific knowledge. Particularly in the current phase of the pandemic (autumn 2020), which is accompanied by a multiplication of the numbers of daily new-onset cases within only a few weeks, such data are highly relevant for the estimation and adjustment of the personnel, structural and organizational needs as well as the capacities for the treatment of patients.</p>","PeriodicalId":41844,"journal":{"name":"Nephrologe","volume":"16 1","pages":"10-13"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7724186/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38372877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From 1969, it enabled survival with a diagnosis that up to then had been fatal; however, with the development of a good network of dialysis centers, the knowledge and experience of HHD was increasingly lost. Today, HHD is practically no longer included in the education. Insufficient information and a lack of HHD services are the result. Currently, less than 0.8% of patients in Germany are treated with HHD. In the development of dialysis machines, the industry focused on stand-alone machines for the centers. This form of treatment hinders mobility and limits the activities of patients with renal insufficiency requiring dialysis. Starting with the Advancing American Kidney Health Initiative there has been a welcome momentum in the development of innovative, wearable and implantable artificial kidneys. This can improve the quality of life and reduce the mortality rate. The first initiatives have also emerged in Germany and Europe. These innovative devices and the associated transition in renal replacement therapy will solve many problems of the nephrology community, such as personnel shortages or the lack of donor organs and death on the waiting list and give patients independence and mobility. The cost burden on healthcare systems can be reduced. In addition, the immense water and electricity consumption will be dramatically reduced by the regenerative techniques of the new machines.</p>","PeriodicalId":41844,"journal":{"name":"Nephrologe","volume":"16 5","pages":"292-298"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s11560-021-00517-y","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39320858","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
