The case for a ketogenic diet in the management of kidney disease.

Ketogenic diets have been widely used for weight loss and are increasingly used in the management of type 2 diabetes. Despite evidence that ketones have multiple positive effects on kidney function, common misconceptions about ketogenic diets, such as high protein content and acid load, have prevented their widespread use in individuals with impaired kidney function. Clinical trial evidence focusing on major adverse kidney events is sparse.

Potential Mechanisms Involved in Chronic Kidney Disease of Unclear Etiology.

Background And Objectives: The etiology of chronic kidney disease of unclear etiology, also known as Mesoamerican nephropathy, remains unclear. We investigated potential etiologies for Mesoamerican nephropathy in an immigrant dialysis population.

Design, Setting, Participants, & Measurements: Migrants with Mesoamerican nephropathy kidney failure (=52) were identified by exclusion of known causes of kidney disease and compared using a cross-sectional survey with demographically similar patients with kidney failure from other causes (=63) and age/sex/place of origin-matched healthy participants (=16).

The impact of COVID-19 on kidney transplantation and the kidney transplant recipient - One year into the pandemic.

The COVID-19 pandemic has significantly changed the landscape of kidney transplantation in the United States and worldwide. In addition to adversely impacting allograft and patient survival in postkidney transplant recipients, the current pandemic has affected all aspects of transplant care, including transplant referrals and listing, organ donation rates, organ procurement and shipping, and waitlist mortality. Critical decisions were made during this period by transplant centers and individual transplant physicians taking into consideration patient safety and resource utilization.

Evidence of nickel and other trace elements and their relationship to clinical findings in acute Mesoamerican Nephropathy: A case-control analysis.

Background: Although there are several hypothesized etiologies of Mesoamerican Nephropathy (MeN), evidence has not yet pointed to the underlying cause. Exposure to various trace elements can cause the clinical features observed in MeN.

Methods And Findings: We measured 15 trace elements, including heavy metals, in renal case-patients (n = 18) and healthy controls (n = 36) in a MeN high-risk region of Nicaragua.

Hip Fracture Risk among Hemodialysis-Dependent Patients Prescribed Opioids and Gabapentinoids.

Background: Despite opioids' known association with hip fracture risk in the general population, they are commonly prescribed to patients with ESKD. Whether use of opioids or gabapentinoids (also used to treat pain in patients with ESKD) contributes to hip fracture risk in patients with ESKD on hemodialysis remains unknown.

Methods: In a case-control study nested within the US Renal Data System, we identified all hip fracture events recorded among patients dependent on hemodialysis from January 2009 through September 2015.

Selective Serotonin Reuptake Inhibitor Use and Hip Fracture Risk Among Patients on Hemodialysis.

Rationale & Objective: Use of selective serotonin reuptake inhibitors (SSRIs) has been associated with hip fracture risk in the general population. This study examined this relationship among patients with kidney failure treated by hemodialysis, a unique high-risk subpopulation, within which the impact of SSRIs on hip fracture risk remains unexplored.

Study Design: Case-control study.

Clinical markers to predict progression from acute to chronic kidney disease in Mesoamerican nephropathy.

An epidemic of chronic kidney disease (CKD) of unknown etiology, known as Mesoamerican Nephropathy (MeN), has been ongoing in Latin America for at least two decades. MeN primarily affects young adults without traditional CKD risk factors, and agricultural workers are disproportionately afflicted. We previously identified an acute phase of MeN that involves acute kidney injury (AKI) with tubulointerstitial nephritis and systemic inflammation.

Mineral and Bone Disorders After Kidney Transplantation.

The risk of mineral and bone disorders among patients with chronic kidney disease is substantially elevated, owing largely to alterations in calcium, phosphorus, vitamin D, parathyroid hormone, and fibroblast growth factor 23. The interwoven relationship among these minerals and hormones results in maladaptive responses that are differentially affected by the process of kidney transplantation. Interpretation of conventional labs, imaging, and other fracture risk assessment tools are not standardized in the post-transplant setting.

Association of Emergency-Only vs Standard Hemodialysis With Mortality and Health Care Use Among Undocumented Immigrants With End-stage Renal Disease.

Importance: Undocumented immigrants with end-stage renal disease have variable access to hemodialysis in the United States despite evidence-based standards for frequency of dialysis care.

Objective: To determine whether mortality and health care use differs among undocumented immigrants who receive emergency-only hemodialysis vs standard hemodialysis (3 times weekly at a health care center).

Design, Setting, And Participants: A retrospective cohort study was conducted of undocumented immigrants with incident end-stage renal disease who initiated emergency-only hemodialysis (Denver Health, Denver, Colorado, and Harris Health, Houston, Texas) or standard (Zuckerberg San Francisco General Hospital, San Francisco, California) hemodialysis between January 1, 2007, and July 15, 2014.

Early detection of acute tubulointerstitial nephritis in the genesis of Mesoamerican nephropathy.

Mesoamerican nephropathy is a devastating disease of unknown etiology that affects mostly young agricultural workers in Central America. An understanding of the mechanism of injury and the early disease process is urgently needed and will aid in identification of the underlying cause and direct treatment and prevention efforts. We sought to describe the renal pathology in Mesoamerican nephropathy at its earliest clinical appearance in prospectively identified acute case patients in Nicaragua.

Clinical Evidence of Acute Mesoamerican Nephropathy.

Mesoamerican nephropathy (MeN), an epidemic of unexplained kidney disease in Central America, affects mostly young, healthy individuals. Its etiology is a mystery that requires urgent investigation. Largely described as a chronic kidney disease (CKD), no acute clinical scenario has been characterized.

Statin use and hip fractures in U.S. kidney transplant recipients.

Background: Basic and translational research supports beneficial effects of statins on bone metabolism. Clinical studies suggest that statin use may reduce the risk of hip fractures in the general population. Whether statin use is associated with hip fracture risk in kidney transplant recipients, a particularly high-risk group for this outcome, is unknown.

Proton Pump Inhibitor Use and Risk of Hip Fracture in Kidney Transplant Recipients.

Background: Posttransplantation bone disease is a significant problem, with few well-evidenced therapeutic options. Proton pump inhibitors (PPIs) are associated with hip fracture in the general population and are widely prescribed for kidney transplant recipients.

Study Design: A case-control study.

Monocyte and plasma expression of TAM ligand and receptor in renal failure: Links to unregulated immunity and chronic inflammation.

Chronic inflammation is increased in patients with chronic kidney disease (CKD) and contributes to cardiovascular morbidity and mortality. Specific immune mechanisms and pathways that drive and maintain chronic inflammation in CKD are not well described. The TAM ligands (Gas6 and protein S) and receptors (Axl and Mer) have been recently recognized as playing a prominent role in immune regulation.
