Novel indications for referral and care for simultaneous liver kidney transplant recipients.

PURPOSE OF REVIEW: Kidney dysfunction is challenging in liver transplant candidates to determine whether it is reversible or not. This review focuses on the pertinent data on how to best approach liver transplant candidates with kidney dysfunction in the current era after implementing the simultaneous liver kidney (SLK) allocation policy and safety net. RECENT FINDINGS: The implementation of the SLK policy inverted the steady rise in SLK transplants and improved the utilization of high-quality kidneys. Access to kidney transplantation following liver transplant alone (LTA) increased with favorable outcomes. Estimating GFR in liver transplant candidates remains challenging, and innovative methods are needed. SLK provided superior patient and graft survival compared to LTA only for patients with advanced CKD and dialysis at least 3 months. SLK can provide immunological protection against kidney rejection in highly sensitized candidates. Post-SLK transplant care is complex, with an increased risk of complications and hospitalization. SUMMARY: The SLK policy improved kidney access and utilization. Transplant centers are encouraged, under the safety net, to reserve SLK for liver transplant candidates with advanced CKD or dialysis at least 3 months while allowing lower thresholds for highly sensitized patients. Herein, we propose a practical approach to liver transplant candidates with kidney dysfunction.

A paradigm shift from office to home-based blood pressure measurement approaches in kidney transplant recipients.

PURPOSE OF REVIEW: The unattended blood pressure (BP) readings from home blood pressure (HBP) monitoring should provide more accurate BP readings than attended BP obtained from office blood pressure (OBP). Here, we review evidence supporting the clinical utility of HBP and automatic remote monitoring of blood pressure (ARM-BP) in kidney transplant recipients (KTR). RECENT FINDINGS: BP from 24-h ambulatory blood pressure monitoring (24-h ABPM) is higher than but better associated with kidney and cardiovascular outcomes compared to OBP and HBP. While there is discordance of BP readings across different BP measurement methods causing BP misclassification, HBP provides BP readings closer to the readings from the 24-h ABPM than those from OBP. Systolic and diastolic BP is better controlled within 30 days after utilizing ARM-BP. SUMMARY: Compared to OBP, HBP minimizes the attended effect of OBP, and its readings are closer to the gold standard 24-h ABPM. ARM-BP improves BP control in the short term and trials of longer follow-up duration are required to evaluate sustained clinical benefits in KTR. The paradigm of BP monitoring may shift toward HBP, while OBP may be utilized primarily for KTR who cannot perform HBP for hypertension diagnosis and management.

Nrf2 Signaling Pathway as a Key to Treatment for Diabetic Dyslipidemia and Atherosclerosis.

Diabetes mellitus (DM) is a chronic endocrine disorder that affects more than 20 million people in the United States. DM-related complications affect multiple organ systems and are a significant cause of morbidity and mortality among people with DM. Of the numerous acute and chronic complications, atherosclerosis due to diabetic dyslipidemia is a condition that can lead to many life-threatening diseases, such as stroke, coronary artery disease, and myocardial infarction. The nuclear erythroid 2-related factor 2 (Nrf2) signaling pathway is an emerging antioxidative pathway and a promising target for the treatment of DM and its complications. This review aims to explore the Nrf2 pathway's role in combating diabetic dyslipidemia. We will explore risk factors for diabetic dyslipidemia at a cellular level and aim to elucidate how the Nrf2 pathway becomes a potential therapeutic target for DM-related atherosclerosis.

Nrf2 Pathway and Oxidative Stress as a Common Target for Treatment of Diabetes and Its Comorbidities.

Diabetes is a chronic disease that induces many comorbidities, including cardiovascular disease, nephropathy, and liver damage. Many mechanisms have been suggested as to how diabetes leads to these comorbidities, of which increased oxidative stress in diabetic patients has been strongly implicated. Limited knowledge of antioxidative antidiabetic drugs and substances that can address diabetic comorbidities through the nuclear factor erythroid 2-related factor 2 (Nrf2) pathway calls for detailed investigation. This review will describe how diabetes increases oxidative stress, the general impact of that oxidative stress, and how oxidative stress primarily contributes to diabetic comorbidities. It will also address how treatments for diabetes, especially focusing on their effects on the Nrf2 antioxidative pathway, have been shown to similarly affect the Nrf2 pathway of the heart, kidney, and liver systems. This review demonstrates that the Nrf2 pathway is a common pathogenic component of diabetes and its associated comorbidities, potentially identifying this pathway as a target to guide future treatments.

A randomized study to compare oral potassium binders in the treatment of acute hyperkalemia.

BACKGROUND: The KBindER (K+ Binders in Emergency Room and hospitalized patients) clinical trial is the first head-to-head evaluation of oral potassium binders (cation-exchange resins) for acute hyperkalemia therapy. METHODS: Emergency room and hospitalized patients with a blood potassium level ≥ 5.5 mEq/L are randomized to one of four study groups: potassium binder drug (sodium polystyrene sulfonate, patiromer, or sodium zirconium cyclosilicate) or nonspecific laxative (polyethylene glycol). Exclusion criteria include recent bowel surgery, ileus, diabetic ketoacidosis, or anticipated dialysis treatment within 4 h of treatment drug. Primary endpoints include change in potassium level at 2 and 4 h after treatment drug. Length of hospital stay, next-morning potassium level, gastrointestinal side effects and palatability will also be analyzed. We are aiming for a final cohort of 80 patients with complete data endpoints (20 per group) for comparative statistics including multivariate adjustment for kidney function, diabetes mellitus, congestive heart failure, metabolic acidosis, renin-angiotensin-aldosterone system inhibitor prescription, and treatment with other agents to lower potassium (insulin, albuterol, loop diuretics). DISCUSSION: The findings from our study will inform decision-making guidelines on the role of oral potassium binders in the treatment of acute hyperkalemia. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT04585542 . Registered 14 October 2020.

Novel therapeutic approaches for COVID-19 in chronic kidney disease and transplant.

PURPOSE OF REVIEW: Severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) is the novel virus responsible for the current worldwide pandemic. The scientific and healthcare communities have made every effort to discover and implement treatment options at a historic pace. Patients with kidney disease are uniquely vulnerable to an infectious pandemic because of their need to be in frequent contact with the healthcare system for life-sustaining renal replacement therapy whether it be by dialysis or transplant. RECENT FINDINGS: The use of targeted viral therapies, extracorporeal therapies, immunosuppressive therapy and public health interventions are important in the management of patients with COVID-19 but require special consideration in patients with kidney disease because of the complexity of their condition. SUMMARY: Here, we discuss some of the major efforts made to prevent spread and emerging treatment options for this virus, as they pertain to patients with kidney disease.

Building a hemodiafiltration system from readily available components for continuous renal replacement therapy under disasters and pandemics: preparing for an acute kidney injury surge during COVID-19.

PURPOSE OF REVIEW: The novel corona virus (SARS-CoV2) has been demonstrated to cause acute kidney injury due to direct cellular toxicity as well as due to a variety of autoimmune glomerular diseases. The concept of a surge of infected patients resulting in an overwhelming number of critical patients has been a central concern in healthcare planning during the COVID-19 era. RECENT FINDINGS: One crucial question remains as to how to manage patients with end stage renal disease and acute kidney injury in case of a massive surge of critically ill infected patients. Some publications address practical and ingenious solutions for just such a surge of need for renal replacement therapy. We present a plan for using a blood pump, readily available dialysis filter, and a prefilter and postfilter replacement fluid set up. This is in conjunction with multiple intravenous pumps to develop a simple hemofiltration apparatus. SUMMARY: The current set up may be a readily available option for use in critical situations where the need for renal replacement therapy outstrips the capacity of traditional hemodialysis services in a hospital or region.

Outcomes of C difficile infection in solid-organ transplant recipients: The National Inpatient Sample (NIS) 2015-2016.

BACKGROUND: Clostridioides (formerly Clostridium) difficile infection (CDI) is one of the leading causes of morbidity and mortality worldwide. Solid organ transplant (SOT) recipients are at an increased risk for CDI. A recent study showed an overall improvement in mortality amongst hospitalized individuals with CDI, but it is unclear if this benefit extends to SOT recipients. METHODS: We scrutinized the 2015 and 2016 National Inpatient Sample (NIS), the largest all-payer inpatient database in the United States for CDI data in patients with SOT. SOT was defined as any recipient who had received a heart, lung, liver, intestinal, kidney, pancreas, or combined thoracic and/or abdominal organ transplantation. Baseline characteristics, comorbidities, and concomitant diagnosis of pneumonia or urinary tract infection were adjusted for in our analysis. Primary outcomes included inpatient mortality, hospital length of stay and total hospital charges. RESULTS: A total of 105 780 hospital discharges of SOT recipients were included. The incidence of CDI was 3554 (3.36%) among SOTs. CDI was associated with a higher inpatient mortality (OR 1.85, 95% CI 1.56-2.20, P < .01), longer length of hospital stay (mean difference 5.07 days, 95% CI 4.43-5.71, P < .01) and higher total hospital charges (mean difference 43 958 US dollars, P < .01). CONCLUSION: Our study found that CDI is associated with poorer overall outcomes among hospitalized SOT recipients. However, there was a possible improving trend of the outcomes when compare to previous studies.

Renal-Cerebral Pathophysiology: The Interplay Between Chronic Kidney Disease and Cerebrovascular Disease.

OBJECTIVES: Cerebrovascular disease has increasingly been linked to overall vascular health. Pathologic conditions like diabetes, hypertension, and kidney disease have been shown to affect brain health and cerebrovascular and nervous systems. Acute kidney injury (AKI) and chronic Kidney Disease (CKD) represent a variety of vascular insults that can adversely affect cerebral health. Hypertension, fluctuations in blood pressure, and diabetic vasculopathy are known risk factors for cerebrovascular disease associated with CKD. Other emerging areas of interest include endothelial dysfunction, vascular calcification due to calcium and phosphorus metabolism dysregulation, and uremic neuropathy present the next frontier of investigation in CKD and cerebrovascular health. METHODS: It has become apparent that the interrelation of AKI and CKD with vascular health, chemical homeostasis, and hormonal regulation upset many aspects of cerebral health and functioning. Stroke is an obvious connection, with CKD patients demonstrating a higher proclivity for cerebrovascular accidents. Cerebral bleeding risk, uremic neuropathies, sodium dysregulation with impacts on nervous system, vascular calcification, and endothelial dysfunction are the next salient areas of research that are likely to reveal key breakthroughs in renal-cerebral pathophysiology. RESULTS: In this review nephrological definition are discussed in a neuro-centric manner, and the areas of key overlap between CKD and cerebrovascular pathology are discussed. The multifaceted effects of renal function on the health of the brain are also examined. CONCLUSION: This review article aims to create the background for ongoing and future neurological-nephrological collaboration on understanding the special challenges in caring for patients with cerebrovascular disease who also have CKD.

A Case of Novel Coronavirus Disease 19 in a Chronic Hemodialysis Patient Presenting with Gastroenteritis and Developing Severe Pulmonary Disease.

Novel coronavirus disease 2019 (COVID-19) is a highly infectious, rapidly spreading viral disease with an alarming case fatality rate up to 5%. The risk factors for severe presentations are concentrated in patients with chronic kidney disease, particularly patients with end-stage renal disease (ESRD) who are dialysis dependent. We report the first US case of a 56-year-old nondiabetic male with ESRD secondary to IgA nephropathy undergoing thrice-weekly maintenance hemodialysis for 3 years, who developed COVID-19 infection. He has hypertension controlled with angiotensin receptor blocker losartan 100 mg/day and coronary artery disease status-post stent placement. During the first 5 days of his febrile disease, he presented to an urgent care, 3 emergency rooms, 1 cardiology clinic, and 2 dialysis centers in California and Utah. During this interval, he reported nausea, vomiting, diarrhea, and low-grade fevers but was not suspected of COVID-19 infection until he developed respiratory symptoms and was admitted to the hospital. Imaging studies upon admission were consistent with bilateral interstitial pneumonia. He was placed in droplet-eye precautions while awaiting COVID-19 test results. Within the first 24 h, he deteriorated quickly and developed acute respiratory distress syndrome (ARDS), requiring intubation and increasing respiratory support. Losartan was withheld due to hypotension and septic shock. COVID-19 was reported positive on hospital day 3. He remained in critical condition being treated with hydroxychloroquine and tocilizumab in addition to the standard medical management for septic shock and ARDS. Our case is unique in its atypical initial presentation and highlights the importance of early testing.

Hyponatremia: A possible immuno-neuroendocrine interface with COVID-19 in a kidney transplant recipient.

There is fast-emerging, cumulative clinical data on coronavirus disease 2019 (COVID-19) in kidney transplant recipients. Although respiratory tract symptoms are often the initial presentation among kidney transplant recipients who contract COVID-19, other clinical features which may indicate underlying SARS-CoV-2-related inflammation, such as gastrointestinal symptoms, are not uncommon. Hyponatremia can develop and may reflect underlying inflammation. Interferon-6 is an important pro-inflammatory cytokine involved in the pathogenesis of severe COVID-19 complications and may play a role in the inappropriately higher secretion of antidiuretic hormone leading to hyponatremia. This pathway is the so-called immuno-neuroendocrine interface. Hyponatremia in COVID-19 has been reported in a few case series of non-kidney transplant patients and only one reported kidney transplant recipient. However, the clinical course and prognostic value of hyponatremia in this population are not described in detail. We report a kidney transplant recipient who was infected with COVID-19 and exhibited severe hyponatremia secondary to the syndrome of inappropriate antidiuretic hormone secretion. Hyponatremia is one of the clinical presentations of COVID-19, although less common, and may occur more frequently in kidney transplant recipients. Thus, the possible underlying immuno-neuroendocrine relationship related to the inflammatory process of COVID-19 leading to hyponatremia and its prognostic value are reviewed.

Dialysate Potassium and Mortality in a Prospective Hemodialysis Cohort.

BACKGROUND: Studies examining the association of dialysate potassium concentration and mortality in hemodialysis patients show conflicting findings. We hypothesized that low dialysate potassium concentrations are associated with higher mortality, particularly in patients with high pre-dialysis serum potassium concentrations. METHODS: We evaluated 624 hemodialysis patients from the prospective Malnutrition, Diet, and Racial Disparities in Kidney Disease study recruited from 16 outpatient dialysis facilities over 2011-2015 who underwent protocolized collection of dialysis treatment characteristics every 6 months. We examined the association of dialysate potassium concentration, categorized as 1, 2, and 3 mEq/L, with all-cause mortality risk in the -overall cohort, and stratified by pre-dialysis serum potassium (< 5 vs. ≥5 mEq/L) using case-mix adjusted Cox models. RESULTS: In baseline analyses, dialysate potassium concentrations of 1 mEq/L were associated with higher mortality, whereas concentrations of 3 mEq/L were associated with similar mortality in the overall cohort (reference: 2 mEq/L): adjusted hazard ratios (aHRs; 95% CI) 1.70 (1.01-2.88) and 0.95 (0.64-1.39), respectively. In analyses stratified by serum potassium, baseline dialysate potassium concentrations of 1 mEq/L were associated with higher mortality in patients with serum potassium ≥5 mEq/L but not in those with serum potassium < 5 mEq/L: aHRs (95% CI) 2.87 (1.51-5.46) and 0.74 (0.27-2.07), respectively (p interaction = 0.04). These findings were robust with incremental adjustment for serum potassium, potassium-binding resins, and potassium-modifying medications. CONCLUSION: Low (1 mEq/L) dialysate potassium -concentrations were associated with higher mortality, particularly in hemodialysis patients with high pre-dialysis serum potassium. Further studies are needed to identify therapeutic strategies that mitigate inter-dialytic serum potassium accumulation and subsequent high dialysate serum potassium gradients in this population.

There's no place like home: 35-year patient survival on home hemodialysis.

The vast majority of maintenance dialysis patients suffer from poor long-term survival rates and lower levels of health-related quality of life. However, home hemodialysis is a historically significant dialysis modality that has been associated with favorable outcomes as well as greater patient autonomy and control, yet only represents a small minority of the total dialysis performed in the United States. Some potential disadvantages of home hemodialysis include vascular access complications, infection-related hospitalizations, patient fatigue, and attrition. In addition, current barriers and challenges in expanding the utilization of this modality include limited patient and provider education and technical expertise. Here we report a 65-year old male with end-stage renal disease due to Alport's syndrome who has undergone 35 years of uninterrupted thrice-weekly home hemodialysis (ie, every Sunday, Tuesday, and Thursday evening, each session lasting 3 to 3» hours in length) using a conventional hemodialysis machine who has maintained a high functional status allowing him to work 6-8 hours per day. The patient has been able to liberalize his dietary and fluid intake while only requiring 3-4 liters of ultrafiltration per treatment, despite having absence of residual kidney function. Through this case of extraordinary longevity and outcomes after 35 years of dialysis and a review of the literature, we illustrate the history of home hemodialysis, its significant clinical and psychosocial advantages, as well as the barriers that hinder its widespread adaptation.

Successful Peritoneal Dialysis Catheter Placement in a New End-Stage Renal Disease Patient with Combined Antiphospholipid Syndrome and Factor XI Deficiency.

Coagulopathies and bleeding disorders can affect dialysis outcomes by increasing the thrombosis risk at the arteriovenous access or by causing prolonged bleeding at access or catheter sites. We present the case of a 68-year-old woman with combined antiphospholipid syndrome and factor XI deficiency, with chronic prolongation of activated partial thromboplastin time that was not correctable with fresh-frozen plasma (FFP).The patient had a history of stroke, but was not on antiplatelet therapy because of mucocutaneous bleeding events. She had progressive renal failure attributed to her autoimmune disease, and a decision was made to pursue peritoneal dialysis (PD) when she reached end-stage kidney disease. She was admitted to the hospital the day before her planned PD catheter placement and was transfused with FFP and platelets before placement of a temporary hemodialysis catheter. One session of hemodialysis was performed to minimize uremic platelet dysfunction. The patient was given additional FFP and platelets at the time of PD catheter placement; desmopressin was not used. No thrombotic or bleeding complications occurred, and at 8 months out, the patient has been doing well on PD.In summary, careful perioperative planning led to successful PD initiation in a patient with combined bleeding and clotting disorders.

E2f1-3 switch from activators in progenitor cells to repressors in differentiating cells.

In the established model of mammalian cell cycle control, the retinoblastoma protein (Rb) functions to restrict cells from entering S phase by binding and sequestering E2f activators (E2f1, E2f2 and E2f3), which are invariably portrayed as the ultimate effectors of a transcriptional program that commit cells to enter and progress through S phase. Using a panel of tissue-specific cre-transgenic mice and conditional E2f alleles we examined the effects of E2f1, E2f2 and E2f3 triple deficiency in murine embryonic stem cells, embryos and small intestines. We show that in normal dividing progenitor cells E2f1-3 function as transcriptional activators, but contrary to the current view, are dispensable for cell division and instead are necessary for cell survival. In differentiating cells E2f1-3 function in a complex with Rb as repressors to silence E2f targets and facilitate exit from the cell cycle. The inactivation of Rb in differentiating cells resulted in a switch of E2f1-3 from repressors to activators, leading to the superactivation of E2f responsive targets and ectopic cell divisions. Loss of E2f1-3 completely suppressed these phenotypes caused by Rb deficiency. This work contextualizes the activator versus repressor functions of E2f1-3 in vivo, revealing distinct roles in dividing versus differentiating cells and in normal versus cancer-like cell cycles.

Outcomes Among Undocumented Immigrant Kidney Transplant Recipients in California.

Importance: There are over 2 million undocumented immigrants (UI) in California, where currently, all individuals regardless of immigration status have access to kidney transplant. There is a medical perception that UI face a higher risk of transplant failure due to language barriers and lack of access to immunosuppressive medication and health care when compared with US residents (UR). Objective: To elucidate the kidney transplant outcomes of UI at an academic medical center in California. Design, Setting, and Participants: A retrospective cohort study was conducted from a single transplant center during an 8-year study period. Patients who received a kidney transplant at the University of California, Irvine, between January 1, 2012, and September 1, 2019, were included in this study. Data were analyzed from October 2020 to August 2021. Exposures: The primary exposure of this study was citizenship status. UI were defined as immigrants residing in the US without permission or legal documentation. Main Outcomes and Measures: The primary end point was all-cause graft loss defined as the return to dialysis, need for a second kidney transplant, or death. The secondary end points of this study were all-cause mortality and rejection. All-cause mortality between the 2 groups was compared using multiple Cox proportional hazard regression analysis. Other transplant outcomes, including all-cause graft loss and acute rejection, were examined by competing risks regressions with mortality and mortality plus graft loss serving as competing risks, respectively. Results: Of all 446 consecutive kidney transplant recipients, the mean (SD) age was 47 (13) years; 261 patients (59%) were male, and 114 (26%) were UI. During a median (IQR) follow-up time of 3.39 (0.04-8.11) years, 6 UI and 48 UR experienced all-cause graft loss. UR had a 192% (hazard ratio, 2.92; 95% CI, 1.21-6.85; P = .01) and 343% (hazard ratio, 4.34; 95% CI, 1.05-18.69; P = .04) significantly increased unadjusted risk for all-cause graft loss and all-cause mortality, respectively. These results became nonsignificant and were mostly attenuated when adjusted for age and ethnicity. Finally, there was no difference in incidence rate of kidney allograft rejection between the 2 groups (UR, 3.5 per 100 person-years vs UI, 2.4 per 100 person-years; rate ratio, 1.45; 95% CI, 0.90-5.05; P = .08). Conclusions and Relevance: This single-center cohort study found that kidney transplant outcomes of UI were not inferior to those of UR. Across the US, however, UI have consistently had unequal access to transplantation. These findings suggest that extending kidney transplants to UI is safe and does not portend worse outcomes. As a result, denying transplant according to immigration status not only results in higher costs but also worse end stage kidney disease outcomes for an already underserved population.

Cell proliferation in the absence of E2F1-3.

E2F transcription factors regulate the progression of the cell cycle by repression or transactivation of genes that encode cyclins, cyclin dependent kinases, checkpoint regulators, and replication proteins. Although some E2F functions are independent of the Retinoblastoma tumor suppressor (Rb) and related family members, p107 and p130, much of E2F-mediated repression of S phase entry is dependent upon Rb. We previously showed in cultured mouse embryonic fibroblasts that concomitant loss of three E2F activators with overlapping functions (E2F1, E2F2, and E2F3) triggered the p53-p21(Cip1) response and caused cell cycle arrest. Here we report on a dramatic difference in the requirement for E2F during development and in cultured cells by showing that cell cycle entry occurs normally in E2f1-3 triply-deficient epithelial stem cells and progenitors of the developing lens. Sixteen days after birth, however, massive apoptosis in differentiating epithelium leads to a collapse of the entire eye. Prior to this collapse, we find that expression of cell cycle-regulated genes in E2F-deficient lenses is aberrantly high. In a second set of experiments, we demonstrate that E2F3 ablation alone does not cause abnormalities in lens development but rescues phenotypic defects caused by loss of Rb, a binding partner of E2F known to recruit histone deacetylases, SWI/SNF and CtBP-polycomb complexes, methyltransferases, and other co-repressors to gene promoters. Together, these data implicate E2F1-3 in mediating transcriptional repression by Rb during cell cycle exit and point to a critical role for their repressive functions in cell survival.

Thrombotic Microangiopathy Syndromes-Common Ground and Distinct Frontiers.

Thrombotic microangiopathies (TMAs) have in common a terminal phenotype of microangiopathic hemolytic anemia with end-organ dysfunction. Thrombotic thrombocytopenic purpura results from von Willebrand factor multimerization, Shiga toxin-mediated hemolytic uremic syndrome causes toxin-induced endothelial dysfunction, while atypical hemolytic uremic syndrome results from complement system dysregulation. Drug-induced TMA, rheumatological disease-induced TMA, and renal-limited TMA exist in an intermediate space that represents secondary complement activation and may overlap with atypical hemolytic uremic syndrome clinically. The existence of TMA without microangiopathic hemolytic features, renal-limited TMA, represents an undiscovered syndrome that responds incompletely and inconsistently to complement blockade. Hematopoietic stem cell transplant-TMA represents another more resistant form of TMA with different therapeutic needs and clinical course. It has become apparent that TMA syndromes are an emerging field in nephrology, rheumatology, and hematology. Much work remains in genetics, molecular biology, and therapeutics to unravel the puzzle of the relationships and distinctions apparent between the different subclasses of TMA syndromes.

Is It Time to Utilize Genetic Testing for Living Kidney Donor Evaluation?

Living donor kidney transplantation is an effective strategy to mitigate the challenges of solid organ shortage. However, being a living kidney donor is not without risk, as donors may encounter short- and long-term complications including the risk of developing chronic kidney disease, end-stage kidney disease, hypertension, and possible pregnancy-related complications. Although the evaluation of potential living donors is a thorough and meticulous process with the intention of decreasing the chance of complications, particularly in donors who have lifetime risk projection, risk factors for kidney disease including genetic predispositions may be missed because they are not routinely investigated. This type of testing may not be offered to patients due to variability and decreased penetrance of symptoms and lack of availability of appropriate genetic testing and genetic specialists. We report a case of a middle-aged woman with a history of gestational diabetes and preeclampsia who underwent an uneventful living kidney donation. She developed postdonation nonnephrotic range proteinuria and microscopic hematuria. Given the risk of biopsy with a solitary kidney, genetic testing was performed and revealed autosomal dominant Alport syndrome. Our case underscores the utility of genetic testing. Hopefully, future research will examine the incorporation of predonation genetic testing into living kidney donor evaluation.
