Study TitleMEND: Muscle Mitochondria Energetics in Chronic Kidney Disease
Principal InvestigatorBryan Kestenbaum
Funding AgencyNIDDK: 5R01DK101509-02
StatusCompleted
Description

People with kidney disease often have muscle weakness and difficulty with mobility. This can affect physical abilities, independence, and quality of life. Mitochondria are the primary energy producing structures in muscle cells. Previous studies suggest that kidney disease may disrupt mitochondrial function; however, these studies have mostly been limited to animal models.

The purpose of this study was to measure mitochondrial properties in people who have chronic kidney disease. We used a specialized procedure to do this in one hand muscle and one leg muscle in 77 participants – 53 kidney disease and 24 controls. We also tested their physical performance using the 6-minute walk test.

Results:

ATPmax – which represents the maximal mitochondrial generation of energy – was lower in the leg muscle of people with CKD but not in the hand muscle. Oxygen uptake was also higher in people with CKD, suggesting a need for more oxygen to achieve the same amount of work. Our specialized measurements of ATPmax tracked strongly with performance on the 6-minute walk test. These results provide further evidence that mitochondrial impairment is an important potential cause of muscle dysfunction in people with chronic kidney disease.

Findings:

This study provides further evidence that kidney disease disrupts the body’s energy producing cells to cause muscle weakness.

Study TitleMENTOR: Membranous Nephropathy Trial Of Rituximab
Principal InvestigatorAshley Jefferson
Funding AgencyMayo Clinic
StatusCompleted
Description

This is a multi-center, prospective, randomized, controlled Phase III trial. This study looks into determining whether Rituximab is non-inferior to Cyclosporine in inducing long-term remission of proteinuria in patients with Idiopathic Membranous Nephropathy.

Results:

A total of 130 patients underwent randomization. At 12 months, 39 of 65 patients (60%) in the rituximab group and 34 of 65 (52%) in the cyclosporine group had a complete or partial remission. At 24 months, 39 patients (60%) in the rituximab group and 13 (20%) in the cyclosporine group had a complete or partial remission. Among patients in remission who tested positive for anti-phospholipase A2 receptor (PLA2R) antibodies, the decline in autoantibodies to anti-PLA2R was faster and of greater magnitude and duration in the rituximab group than in the cyclosporine group. Rituximab was non-inferior to cyclosporine in inducing complete or partial remission of proteinuria at 12 months and was superior in maintaining proteinuria remission up to 24 months.

Findings:

Rituximab’s performance was equivalent to Cyclosporine at 12 months and superior at 24 months. Both drugs may be used to treat or prevent the progression of abnormal quantities of protein in the urine but this study showed that Rituximab may be the more effective option in the longer term.

Study TitlePROCLAIM: Proximal Tubule Clearance of Renal Medications Study
Principal InvestigatorBryan Kestenbaum
Funding AgencyNIDDK
StatusCompleted
Description

The kidney tubules are responsible for eliminating hundreds of prescribed medications. Yet, kidney drug dosing is still based on the glomerular filtration rate – a different kidney function. The goal of this study was to compare tubular clearance and the glomerular filtration rate as predictors of kidney drug elimination. We administered two common medications for this purpose: furosemide and penciclovir to 54 people with a wide range of kidney function from chronic kidney disease to normal.

Results:

Kidney tubular clearance strongly predicted the elimination of both test medications. However, the glomerular filtration was only slightly less predictive of kidney medication clearance, suggesting that, among stable outpatients, these two kidney functions are in fact tightly linked. Additional studies are underway to compare these kidney functions in different disease settings, such as acute kidney injury, and for different medications.

Findings:

This study shows that tubular secretory clearance, a kidney function not measured in practice, can be used to accurately predict kidney drug elimination.
