The drug development pipeline for kidney diseases is plagued with challenges ranging from an insufficient understanding of disease mechanisms to a lack of robust preclinical models. Bioengineering approaches have the potential to streamline preclinical drug discovery efforts and improve the success of clinical trials for kidney disease.
Interest in the use of haemoperfusion for severe COVID-19 has been spurred by anecdotal reports of its efficacy and expert reviews suggesting theoretical benefits. However, on the basis of the limited current evidence, haemoperfusion remains an experimental therapy that should only be applied within the context of well-designed randomized trials.
Chronic kidney disease (CKD) is a rapidly growing public health problem, especially in disadvantaged populations. Major political interventions are required to mitigate the social and socioeconomic inequities that contribute to the development and progression of CKD and its disproportionate impact on low and middle-income countries.
A host of innovative developments in dialysis technologies could potentially transform the field, with benefits for patient outcomes, access to therapy and environmental sustainability.
Public policy for kidney replacement therapy eludes most low- and middle-income countries owing to the seemingly low number of cases and high cost. Countries such as Thailand have shown that public health authorities can effectively provide treatment and elevate health care for populations by overcoming some common challenges.
Management of kidney transplant recipients requires a sustainable infrastructure that can provide reliable medical care both before and after transplantation. The COVID-19 pandemic has disrupted transplant referral and listing processes, led to decreases in the numbers of transplant procedures and resulted in changes in practice for pre- and post-transplantation management and follow-up.
The COVID-19 pandemic has placed a tremendous strain on sustaining the clinical research enterprise and will also likely affect key study outcomes; these effects must be considered during data analysis and interpretation. Nevertheless, the responses to the pandemic have also introduced innovations that will advance the conduct of clinical research.
Reports of collapsing glomerulopathy in patients of African ancestry and high-risk APOL1 genotype infected with SARS-CoV-2 have emerged during the COVID-19 pandemic. This new entity, which we term COVID-19-associated nephropathy (COVAN), may particularly impact individuals in some regions of the world. Awareness of this potentially ominous complication of COVID-19 must be raised.
Continuous kidney replacement therapy (CKRT) can be a lifesaving intervention for critically ill patients; however, mortality remains high. The adaptation of existing innovations, including anti-clotting measures; cloud-computing for optimized treatment prescribing and therapy monitoring; and real-time sensing of blood and/or filter effluent composition to CKRT devices has the potential to enable personalized care and improve the safety and efficacy of this therapy.
Brazil has been severely affected by the novel coronavirus. At a time when the country needs to concentrate on controlling and fighting the virus, President Bolsonaro has minimized the importance of the pandemic and focused on political battles.
The most common treatment option worldwide for persons with kidney failure is in-centre haemodialysis; however, this treatment has remained largely unchanged over decades owing to a lack of true patient-centred technological innovation. The development of safe and effective wearable forms of dialysis has the potential to transform the lives of these patients.
Health-care workers involved in the response to the COVID-19 pandemic are often required to work in highly challenging conditions and may therefore be at increased risk of experiencing mental health problems. This Comment sets out a practical approach to protecting the mental health of health-care workers based on contemporary evidence.
