Integrating Patient Priorities with Science by Community Engagement in the Kidney Precision Medicine Project

Developing a Quality Improvement Framework to Enhance the Health System User Experience for Individuals Living With Type 1 Diabetes: The Reshape T1D Study

INTRODUCTION

User experience design aims to create products and services that are accessible, usable, and enjoyable. The Reshape T1D study aims to apply these principles to understand how individuals living with T1D interact with and experience healthcare to inform T1D clinical quality improvement.

METHODS

Using a community-based participatory research design, we involved four patients and four clinicians as co-researchers throughout the research. A questionnaire and virtual semi-structured interview were applied across a purposeful sample of 41 adults living with T1D across Alberta, Canada, between September 2021 and May 2022. Audio recordings were transcribed verbatim and de-identified before coding. Thematic analysis was conducted on coded participant discourse through multiple coders.

RESULTS

Participants indicated the need for a centralized hub that provides consistent, reliable, and up-to-date T1D education and resources and an emphasis on access to mental health resources within T1D care settings. Providing greater flexibility for appointment types (ie. in-person, virtual, etc.) and after-hours access contributed to better self-management and prevented emergency room visits. Participants desired a choice as to who comprises their T1D care team and for teams to address patient needs specific to their reality. We identified that medical trauma had long-term impacts on perceptions of healthcare and contributed to a reluctance to seek future care. Women expressed challenges in discussing reproductive health with their clinicians. Diabetes online communities provide an adjunct to clinical care through peer support. Cost and access to the latest technology are ongoing barriers for many participants, especially concerning publicly funded programmes that use advanced insulin pump therapy, continuous glucose monitoring, and automated insulin delivery systems. A quality improvement framework emerged through data analysis, and findings were synthesized into actionable recommendations for ongoing clinical quality improvement.

CONCLUSION

Our findings highlight how important health system user suggestions are for more equitable, accessible, and empathetic healthcare for individuals living with T1D. Further work is needed to explore health system user experiences with clinicians and healthcare administrators to effectively carry out T1D clinical quality improvement.

Consideration and Disclosure of Group Risks in Genomics and Other Data-Centric Research: Does the Common Rule Need Revision?

Harms and risks to groups and third-parties can be significant in the context of research, particularly in data-centric studies involving genomic, artificial intelligence, and/or machine learning technologies. This article explores whether and how United States federal regulations should be adapted to better align with current ethical thinking and protect group interests. Three aspects of the Common Rule deserve attention and reconsideration with respect to group interests: institutional review board (IRB) assessment of the risks/benefits of research; disclosure requirements in the informed consent process; and criteria for waivers of informed consent. In accordance with respect for persons and communities, investigators and IRBs should systematically consider potential group harm when designing and reviewing protocols, respectively. Research participants should be informed about any potential group harm in the consent process. We call for additional public discussion, empirical research, and normative analysis on these issues to determine the right regulatory and policy path forward.

Community Engagement Studios to advance multi-site research with older adults

Introduction

Operationalizing multi-site Community Engagement (CE) Studios to inform a research program is valuable for researchers. We describe the process and outcomes of hosting three CE Studios with Community Experts aged 65 years or older with chronic conditions and care partners of older adults. Experts gave feedback about processes for testing the feasibility, efficacy, effectiveness, and implementation of audio recording clinic visits and sharing recordings with patients who have multimorbidity and their care partners.

Methods

The CE Cores of the Clinical and Translational Science Awards Programs at three academic health science centers created a joint CE Studio guide. Studios were conducted iteratively by site. Following receipt of the final reports, responses were compared to find themes, similarities, and differences on four topics in addition to overall commentary: Recruitment and Retention, Study Protocol, Study Reminders and Frequency, and Recording Technology.

Results

Eighteen older adults and care partners in three states provided valuable feedback to inform multi-site trials. Feedback influenced multiple aspects of trials in process or subsequently funded. Experts provided critique on the wording of study invitations, information sheets, and reminders to engage in study procedures. Experts were concerned for participants being disappointed by randomization to a control arm and advised how investigators should prepare to address that.

Conclusions

Multi-site CE Studios should be consecutive, so each team can learn from the previous teams. Using the CES Toolkit ensures that final reports were easily comparable and utilized to develop a research program that now includes three federally funded clinical trials.

Precision Medicine in Nephrology: An Integrative Framework of Multidimensional Data in the Kidney Precision Medicine Project

Chronic kidney disease (CKD) and acute kidney injury (AKI) are heterogeneous syndromes defined clinically by serial measures of kidney function. Each condition possesses strong histopathologic associations, including glomerular obsolescence or acute tubular necrosis, respectively. Despite such characterization, there remains wide variation in patient outcomes and treatment responses. Precision medicine efforts, as exemplified by the Kidney Precision Medicine Project (KPMP), have begun to establish evolving, spatially anchored, cellular and molecular atlases of the cell types, states, and niches of the kidney in health and disease. The KPMP atlas provides molecular context for CKD and AKI disease drivers and will help define subtypes of disease that are not readily apparent from canonical functional or histopathologic characterization but instead are appreciable through advanced clinical phenotyping, pathomic, transcriptomic, proteomic, epigenomic, and metabolomic interrogation of kidney biopsy samples. This perspective outlines the structure of the KPMP, its approach to the integration of these diverse datasets, and its major outputs relevant to future patient care.

Participant Experience with Protocol Research Kidney Biopsies in the Kidney Precision Medicine Project

BACKGROUND

Kidney biopsies are procedures commonly performed in clinical nephrology and are increasingly used in research. In this study, we aimed to evaluate the experiences of participants who underwent research kidney biopsies in the Kidney Precision Medicine Project (KPMP).

METHODS

KPMP research participants with AKI or CKD were enrolled at nine recruitment sites in the United States between September 2019 and January 2023. At 28 days postbiopsy, participants were invited to complete a survey to share their experiences, including motivation to participate in research, comprehension of informed consent, pain and anxiety during and after the biopsy procedure, overall satisfaction with KPMP participation, and effect of the study on their lives. The survey was developed in collaboration with the KPMP Community Engagement Committee and the Institute of Translational Health Sciences at the University of Washington.

RESULTS

One hundred and eleven participants completed the survey, 23 enrolled for AKI and 88 for CKD. The median age was 61 (interquartile range [IQR], 48-67) years, 43% were women, 28% were Black, and 18% were of Hispanic ethnicity. Survey respondents most commonly joined KPMP to help future patients (59%). The consent form was understood by 99%, and 97% recognized their important role in this study. Pain during the biopsy was reported by 50%, at a median level of 1 (IQR, 0-3) on a 0-10 scale. Anxiety during the biopsy was described by 64% at a median level of 3 (IQR, 1-5) on a 0-10 scale. More than half conveyed that KPMP participation had an effect on their diet, physical activity, and how they think about kidney disease.

CONCLUSIONS

KPMP survey respondents were most commonly motivated to participate in research protocol kidney biopsies by altruism, with excellent understanding of the informed consent process.

Multimodal approaches for inequality in kidney care: turning social determinants of health into opportunities

PURPOSE OF REVIEW

Kidney disease is associated with major health and economic burdens worldwide, disproportionately carried by people in low and middle socio-demographic index quintile countries and in underprivileged communities. Social determinants such as education, income and living and working conditions strongly influence kidney health outcomes. This review synthesised recent research into multimodal interventions to promote kidney health equity that focus on the social determinants of health.

RECENT FINDINGS

Inequity in kidney healthcare commonly arises from nationality, race, sex, food insecurity, healthcare access and environmental conditions, and affects kidney health outcomes such as chronic kidney disease progression, dialysis and transplant access, morbidity and mortality. Multimodal approaches to addressing this inequity were identified, targeted to: patients, families and caregivers (nutrition, peer support, financial status, patient education and employment); healthcare teams (workforce, healthcare clinician education); health systems (data coding, technology); communities (community engagement); and health policy (clinical guidelines, policy, environment and research).

SUMMARY

The engagement of diverse patients, families, caregivers and communities in healthcare research and implementation, as well as clinical care delivery, is vital to counteracting the deleterious effects of social determinants of kidney health.

Kidney Biopsy Utility: Patient and Clinician Perspectives from the Kidney Precision Medicine Project

Rationale & Objective

Limited data exist on patient perspectives of the implications of kidney biopsies. We explored patients' perspectives alongside those of clinicians to better understand how kidney biopsies affect patients' viewpoints and the clinical utility of biopsies.

Study Design

Prospective Cohort Study.

Setting & Participants

Patient participants and clinicians in the Kidney Precision Medicine Project, a prospective cohort study of patients who undergo a research protocol biopsy, at 9 recruitment sites across the United States. Surveys were completed at enrollment before biopsy and additional timepoints after biopsy (participants: 28 days, 6 months; clinicians: 2 weeks).

Analytical Approach

Kappa statistics assessed prebiopsy etiology concordance between clinicians and participants. Participant perspectives after biopsy were analyzed using a thematic approach. Clinician ratings of clinical management value were compared to prebiopsy ratings with Wilcoxon matched-pairs signed-rank tests and paired t tests.

Results

A total of 167 participants undergoing biopsy (124 participants with chronic kidney disease [CKD], 43 participants with acute kidney injury [AKI]) and 58 clinicians were included in this study. CKD participants and clinicians had low etiology concordance for the 2 leading causes of CKD: diabetes (k = 0.358) and hypertension (k = 0.081). At 28 days postbiopsy, 46 (84%) participants reported that the biopsy affected their understanding of their diagnosis, and 21 (38%) participants reported that the results of the biopsy affected their medications. Participants also shared biopsy impressions in free-text responses, including impacts on lifestyle and concurrent condition management. The biopsy positively shifted clinician perceptions of the procedure's clinical management benefits, while perceptions of prognostic value decreased and diagnostic ratings remained unchanged.

Limitations

Our study did not have demographic data of clinicians and could not provide insight into postbiopsy experiences for participants who did not respond to follow-up surveys.

Conclusions

Participant perspectives of the personal implications of kidney biopsy can be integrated into shared decision-making between clinicians and patients. Enhanced biopsy reports and interactions between nephrologists and pathologists could augment the management and prognostic value of kidney biopsies.

Plain-Language Summary

The utility of kidney biopsy is debated among clinicians, and patients' perspectives are even less explored. To address these gaps, we synthesized perspectives from clinicians and patient participants of the Kidney Precision Medicine Project (KPMP). Both before and after biopsy, clinicians were surveyed on how the procedure affected their clinical management, diagnosis, and prognosis. After biopsy, participants shared how the procedure affected their diagnosis, medication, and lifestyle changes. Clinicians and patients shared an appreciation for the biopsy's impact on medical management but diverged in their takeaways on diagnosis and prognosis. These findings highlight the need for greater collaboration between patients and clinicians, particularly as they navigate shared decision-making when considering kidney biopsy.

Applying Genetic and Genomic Tools to Psychiatric Disorders: A Scoping Review

INTRODUCTION

The bioethics literature reflects significant interest in and concern with the use of genetic and genomic information in various settings. Because psychiatric treatment and research raises unique ethical, legal, and social issues, we conducted a scoping review of the biomedical, bioethics, and psychology literature regarding the application of genetic and genomic tools to psychiatric disorders (as listed in the DSM-5) and two associated behaviors or symptoms to provide a more detailed overview of the state of the field.

OBJECTIVES

The primary objective was to examine the available bioethics, biomedical, and psychology literature on applying genetic and genomic tools to psychiatric disorders (other than neurodevelopmental disorders) and two behaviors or symptoms sometimes associated with them (aggression or violence and suicidality) to identify the disorders to which these tools have been applied, the contexts in or purposes for which they have been applied, the ethical, legal, or social concerns associated with those uses, and proposed recommendations for mitigating those concerns.

METHODS

We used Arksey and O'Malley's scoping review framework: (1) identify the research question; (2) identify relevant studies; (3) select studies; (4) chart the data; and (5) collate, summarize, and report results (2005). We relied on Levac et al. to inform our application of the framework (2010). The PRISMA extension for scoping reviews checklist informed our reporting (2018). We searched three electronic databases MEDLINE (PubMed), Embase, and PsycInfo (EbscoHost) for peer-reviewed journal articles in English to identify relevant literature. One author screened the initial results and additional screening was done in consultation with other authors. A data extraction form using DSM-5 diagnostic categories (excluding neurodevelopmental disorders) was developed and two authors independently each reviewed approximately half of the articles. Inter-rater reliability was ensured by double-coding approximately 10% of the papers. An additional author independently coded 10% of the articles to audit the data.

RESULTS

In 365 coded publications, we identified 15 DSM-5 diagnostic categories in addition to the two pre-selected behaviors or symptoms (aggression or violence and suicidality) to which genetic or genomic tools have been applied. We identified 11 settings in or purposes for which these tools were applied. Twenty-two types of ethical, legal, or social concerns associated with the application of genetic or genomic tools to these disorders or behaviors/symptoms were identified along with 13 practices or policies that could mitigate these concerns.

CONCLUSION

Genetic and genomic tools have been applied to a wide range of psychiatric disorders. These raise a range of ethical, legal, and social concerns. Additional research is warranted to better understand the concerns and effective ways to address them. Advancing the literature to identify relevant ethical, legal, or social concerns and solutions to those problems likely requires greater attention to specific applications of genetic or genomic tools to particular psychiatric disorders and associated behaviors/symptoms as well as broad stakeholder engagement.

Community Engagement in Precision Medicine Research: Organizational Practices and Their Impacts for Equity

BACKGROUND

In the wake of mandates for biomedical research to increase participation by members of historically underrepresented populations, community engagement (CE) has emerged as a key intervention to help achieve this goal.

METHODS

Using interviews, observations, and document analysis, we examine how stakeholders in precision medicine research understand and seek to put into practice ideas about who to engage, how engagement should be conducted, and what engagement is for.

RESULTS

We find that ad hoc, opportunistic, and instrumental approaches to CE exacted significant consequences for the time and resources devoted to engagement and the ultimate impacts it has on research. Critical differences emerged when engagement and research decisionmaking were integrated with each other versus occurring in parallel, separate parts of the study organization, and whether community members had the ability to determine which issues would be brought to them for consideration or to revise or even veto proposals made upstream based on criteria that mattered to them. CE was understood to have a range of purposes, from instrumentally facilitating recruitment and data collection, to advancing community priorities and concerns, to furthering long-term investments in relationships with and changes in communities. These choices about who to engage, what engagement activities to support, how to solicit and integrate community input into the workflow of the study, and what CE was for were often conditioned upon preexisting perceptions and upstream decisions about study goals, competing priorities, and resource availability.

CONCLUSIONS

Upstream choices about CE and constraints of time and resources cascade into tradeoffs that often culminated in "pantomime community engagement." This approach can create downstream costs when engagement is experienced as improvised and sporadic. Transformations are needed for CE to be seen as a necessary scientific investment and part of the scientific process.

Diabetes Management in Chronic Kidney Disease: A Consensus Report by the American Diabetes Association (ADA) and Kidney Disease: Improving Global Outcomes (KDIGO)

People with diabetes and chronic kidney disease (CKD) are at high risk for kidney failure, atherosclerotic cardiovascular disease, heart failure, and premature mortality. Recent clinical trials support new approaches to treat diabetes and CKD. The 2022 American Diabetes Association (ADA) Standards of Medical Care in Diabetes and the Kidney Disease: Improving Global Outcomes (KDIGO) 2022 Clinical Practice Guideline for Diabetes Management in Chronic Kidney Disease each provide evidence-based recommendations for management. A joint group of ADA and KDIGO representatives reviewed and developed a series of consensus statements to guide clinical care from the ADA and KDIGO guidelines. The published guidelines are aligned in the areas of CKD screening and diagnosis, glycemia monitoring, lifestyle therapies, treatment goals, and pharmacologic management. Recommendations include comprehensive care in which pharmacotherapy that is proven to improve kidney and cardiovascular outcomes is layered on a foundation of healthy lifestyle. Consensus statements provide specific guidance on use of renin-angiotensin system inhibitors, metformin, sodium-glucose cotransporter 2 inhibitors, glucagon-like peptide 1 receptor agonists, and a nonsteroidal mineralocorticoid receptor antagonist. These areas of consensus provide clear direction for implementation of care to improve clinical outcomes of people with diabetes and CKD.

Present and future directions in diabetic kidney disease

Diabetic kidney disease (DKD) is the leading cause of kidney failure and is associated with substantial risk of cardiovascular disease, morbidity, and mortality. Traditionally, DKD prevention and management have focused on addressing hyperglycemia, hypertension, obesity, and renin-angiotensin system activation as important risk factors for disease. Over the last decade, sodium-glucose cotransporter-2 inhibitors and glucagon-like peptide-1 receptor agonists have been shown to meaningfully reduce risk of diabetes-related kidney and cardiovascular complications. Additional agents demonstrating benefit in DKD such as non-steroidal mineralocorticoid receptor antagonists and endothelin A receptor antagonists are further contributing to the growing arsenal of DKD therapies. With the availability of greater therapeutic options comes the opportunity to individually optimize DKD prevention and management. Novel applications of transcriptomic, proteomic, and metabolomic/lipidomic technologies, as well as use of artificial intelligence and reinforced learning methods through consortia such as the Kidney Precision Medicine Project and focused studies in established cohorts hold tremendous promise for advancing our understanding and treatment of DKD. Specifically, enhanced understanding of the molecular mechanisms underlying DKD pathophysiology may allow for the identification of new mechanism-based DKD subtypes and the development and implementation of targeted therapies. Implementation of personalized care approaches has the potential to revolutionize DKD care.

Designing Interventions Addressing Structural Racism to Reduce Kidney Health Disparities: A Report from a National Institute of Diabetes and Digestive and Kidney Diseases Workshop

Structural racism embodies the many ways in which society fosters racial discrimination through "mutually reinforcing inequitable systems" that limit access to resources and opportunities that can promote health and well being among marginalized communities. To achieve health equity, and kidney health equity more specifically, structural racism must be eliminated. In February 2022, the National Institute of Diabetes and Digestive and Kidney Diseases convened the "Designing Interventions that Address Structural Racism to Reduce Kidney Health Disparities" workshop, which was aimed at describing the mechanisms through which structural racism contributes to health and health care disparities for people along the continuum of kidney disease and identifying actionable opportunities for interventional research focused on dismantling or addressing the effects of structural racism. Participants identified six domains as key targets for interventions and future research: (1) apply an antiracism lens, (2) promote structural interventions, (3) target multiple levels, (4) promote effective community and stakeholder engagement, (5) improve data collection, and (6) advance health equity through new health care models. There is an urgent need for research to develop, implement, and evaluate interventions that address the unjust systems, policies, and laws that generate and perpetuate inequities in kidney health.

Diabetes management in chronic kidney disease: a consensus report by the American Diabetes Association (ADA) and Kidney Disease: Improving Global Outcomes (KDIGO)

The Michigan O'Brien Kidney Research Center: transforming translational kidney research through systems biology

Research on kidney diseases is being transformed by the rapid expansion and innovations in omics technologies. The analysis, integration, and interpretation of big data, however, have been an impediment to the growing interest in applying these technologies to understand kidney function and failure. Targeting this urgent need, the University of Michigan O'Brien Kidney Translational Core Center (MKTC) and its Administrative Core established the Applied Systems Biology Core. The Core provides need-based support for the global kidney community centered on enabling incorporation of systems biology approaches by creating web-based, user-friendly analytic and visualization tools, like Nephroseq and Nephrocell, guiding with experimental design, and processing, analysis, and integration of large data sets. The enrichment core supports systems biology education and dissemination through workshops, seminars, and individualized training sessions. Meanwhile, the Pilot and Feasibility Program of the MKTC provides pilot funding to both early-career and established investigators new to the field, to integrate a systems biology approach into their research projects. The relevance and value of the portfolio of training and services offered by MKTC are reflected in the expanding community of young investigators, collaborators, and users accessing resources and engaging in systems biology-based kidney research, thereby motivating MKTC to persevere in its mission to serve the kidney research community by enabling access to state-of-the-art data sets, tools, technologies, expertise, and learning opportunities for transformative basic, translational, and clinical studies that will usher in solutions to improve the lives of people impacted by kidney disease.

A Participant-Centered Approach to Understanding Risks and Benefits of Participation in Research Informed by the Kidney Precision Medicine Project

An understanding of the ethical underpinnings of human subjects research that involves some risk to participants without anticipated direct clinical benefit-such as the kidney biopsy procedure as part of the Kidney Precision Medicine Project (KPMP)-requires a critical examination of the risks as well as the diverse set of countervailing potential benefits to participants. This kind of deliberation has been foundational to the development and conduct of the KPMP. Herein, we use illustrative features of this research paradigm to develop a more comprehensive conceptualization of the types of benefits that may be important to research participants, including respecting pluralistic values, supporting the opportunity to act altruistically, and enhancing benefits to a participant's community. This approach may serve as a model to help researchers, ethicists, and regulators to identify opportunities to better respect and support participants in future research that entails some risk to these participants as well as to improve the quality of research for people with kidney disease.

Molecular Signatures of Diabetic Kidney Disease Hiding in a Patient with Hypertension-Related Kidney Disease: A Clinical Pathologic Molecular Correlation

The Kidney Precision Medicine Project (KPMP) seeks to establish a molecular atlas of the kidney in health and disease and improve our understanding of the molecular drivers of CKD and AKI. Herein, we describe the case of a 66-year-old woman with CKD who underwent a protocol KPMP kidney biopsy. Her clinical history included well-controlled diabetes mellitus, hypertension, and proteinuria. The patient's histopathology was consistent with modest hypertension-related kidney injury, without overt diabetic kidney disease. Transcriptomic signatures of the glomerulus, interstitium, and tubular subsegments were obtained from laser microdissected tissue. The molecular signatures that were uncovered revealed evidence of early diabetic kidney disease adaptation and ongoing active tubular injury with enriched pathways related to mesangial cell hypertrophy, glycosaminoglycan biosynthesis, and apoptosis. Molecular evidence of diabetic kidney disease was found across the nephron. Novel molecular assays can supplement and enrich the histopathologic diagnosis obtained from a kidney biopsy.

Precision medicine for the treatment of glomerulonephritis: A bold goal but not yet a transformative achievement

The revolution in our ability to recognize the alterations in fundamental biology brought about by disease has fostered a renewed interest in precision or personalized medicine (“the right treatment, or diagnostic test, for the right patient at the right time”). This nascent field has been led by oncology, immune-hematology and infectious disease, but nephrology is catching up, and quickly. Specific forms of glomerulonephritis thought to represent specific “diseases” have been “downgraded” to “patterns of injury”. New entities have emerged through application of sophisticated molecular technologies; often embraced by the term “multi-omics”. Kidney biopsies are now interpreted by next generation imaging and machine learning. Many opportunities are manifest that will translate these remarkable developments into novel safe and effective treatment regimens for specific pathogenic pathways evoking glomerulonephritis and its progression to kidney failure. A few successes emboldens a positive look to the future. A sustained and highly collaborative engagement with this new paradigm will be required for this field, full of hope and high expectations, to realize its goal of transforming glomerular therapeutics from “one size fits all (or many)” to a true individualized management principle.

Improving Clinical Trials for Anticomplement Therapies in Complement-Mediated Glomerulopathies: Report of a Scientific Workshop Sponsored by the National Kidney Foundation

Blocking the complement system as a therapeutic strategy has been proposed for numerous glomerular diseases but presents myriad questions and challenges, not the least of which is demonstrating efficacy and safety. In light of these potential issues and because there are an increasing number of anticomplement therapy trials either planned or under way, the National Kidney Foundation facilitated an all-virtual scientific workshop entitled "Improving Clinical Trials for Anti-Complement Therapies in Complement-Mediated Glomerulopathies." Attended by patient representatives and experts in glomerular diseases, complement physiology, and clinical trial design, the aim of this workshop was to develop standards applicable for designing and conducting clinical trials for anticomplement therapies across a wide spectrum of complement-mediated glomerulopathies. Discussions focused on study design, participant risk assessment and mitigation, laboratory measurements and biomarkers to support these studies, and identification of optimal outcome measures to detect benefit, specifically for trials in complement-mediated diseases. This report summarizes the discussions from this workshop and outlines consensus recommendations.

Patient perspectives and involvement in precision medicine research

The Kidney Precision Medicine Project will advance understanding of chronic kidney disease attributed to diabetes or hypertension and acute kidney injury through a protocol kidney biopsy used for deep phenotyping with state-of-the-art methodology. To guide scientific inquiry toward clinically meaningful benefit, patients are equal partners for priority setting, study design and conduct, and dissemination of findings. Patients from stakeholder organizations, recruitment sites, tissue interrogation sites, and the Central Hub are represented on the Community Engagement Committee. This unique collaboration between patients and scientists has set a new standard for inclusion in precision medicine research.

Rationale and design of the Kidney Precision Medicine Project

Chronic kidney disease (CKD) and acute kidney injury (AKI) are common, heterogeneous, and morbid diseases. Mechanistic characterization of CKD and AKI in patients may facilitate a precision-medicine approach to prevention, diagnosis, and treatment. The Kidney Precision Medicine Project aims to ethically and safely obtain kidney biopsies from participants with CKD or AKI, create a reference kidney atlas, and characterize disease subgroups to stratify patients based on molecular features of disease, clinical characteristics, and associated outcomes. An additional aim is to identify critical cells, pathways, and targets for novel therapies and preventive strategies. This project is a multicenter prospective cohort study of adults with CKD or AKI who undergo a protocol kidney biopsy for research purposes. This investigation focuses on kidney diseases that are most prevalent and therefore substantially burden the public health, including CKD attributed to diabetes or hypertension and AKI attributed to ischemic and toxic injuries. Reference kidney tissues (for example, living-donor kidney biopsies) will also be evaluated. Traditional and digital pathology will be combined with transcriptomic, proteomic, and metabolomic analysis of the kidney tissue as well as deep clinical phenotyping for supervised and unsupervised subgroup analysis and systems biology analysis. Participants will be followed prospectively for 10 years to ascertain clinical outcomes. Cell types, locations, and functions will be characterized in health and disease in an open, searchable, online kidney tissue atlas. All data from the Kidney Precision Medicine Project will be made readily available for broad use by scientists, clinicians, and patients.
