Dr. Julia Lewis, MD, Lead Investigator Nephrologist and Professor of Medicine Vanderbilt University Medical CenterMedicalResearch.com Interview with: Dr. Julia Lewis, MD, Lead Investigator Nephrologist and Professor of Medicine Vanderbilt University Medical Center Medical Research: What is the background for this study? What are the main findings? Dr. Lewis: The 48-week Open Label Extension (OLE) study for Auryxia™ (ferric citrate) was conducted to determine long term safety following the Phase 3 52-week active-control period. The study also evaluated changes in serum phosphorus, transferrin saturation (TSAT), serum ferritin, hemoglobin, hematocrit and additional parameters, as well as intravenous (IV) iron and erythropoiesis-stimulating agent (ESA) usage. In the OLE study, Auryxia demonstrated long-term safety in dialysis-dependent chronic kidney disease (CKD) patients. The results were consistent with those seen in the published pivotal Phase 3 trial. The study demonstrated that the adverse events (AE’s) profile of Auryxia was similar to that seen in the Phase 3 52-week active-control period. AEs occurred in 142 patients treated with Auryxia. They were primarily non-serious gastrointestinal (GI) - related AE’s, including diarrhea, nausea, vomiting and constipation. Serious adverse events occurred in 75 patients, though none were related to Auryxia. In addition, there were no clinically or statistically significant differences in liver enzymes or aluminum levels observed from baseline to the end of the 48 weeks. Similar to the original trial, we witnessed excellent phosphorus control with the drug, along with an increase and then a plateau in serum ferritin and TSAT levels with Auryxia. The plateauing of serum ferritin and TSAT further supports iron absorption is highly regulated by the gastrointestinal track as seen in the 52-week active control period. This suggests that the body absorbs iron as needed for effective erythropoiesis. Additionally, iron store increases from ferric citrate resulted in, by the end of the extension study, 85% of subjects not using any IV iron. We presented this data at the 2014 American Society of Nephrology Meeting. The abstract can be found online at www.asn-online.org. (more…)

Giovanni Landoni, M.D. Head of Research,Department of Anesthesiology and Intensive Care Associate Professor at Università Vita-Salute San Raffaele, MilanMedicalResearch.com Interview with: Giovanni Landoni, M.D. Head of Research,Department of Anesthesiology and Intensive Care Associate Professor at Università Vita-Salute San Raffaele, Milan Medical Research: What is the background for this study? Dr. Landoni: The prevention and treatment of acute kidney injury after cardiac surgery is a major therapeutic goal, but no effective agents have yet been identified. Meta-analyses suggested that fenoldopam might be effective. Medical Research: What are the main findings? Dr. Landoni: We found that in cardiac surgery patients with early acute kidney injury (defined as a ≥50% increase of serum creatinine from baseline or oliguria for ≥6 hours), fenoldopam had no impact on the need for renal replacement therapy or 30-day mortality, while increasing the rate of hypotension.

Dr Jelena Kornej Department of Electrophysiology Heart Center Leipzig Leipzig Germany;MedicalResearch.com Interview with: Dr Jelena Kornej Department of Electrophysiology Heart Center Leipzig Leipzig Germany; Medical Research: What are the main findings of the study? Dr. Komej: Both atrial fibrillation (AF) and renal impairment are known to coexist and associated with increased morbidity and mortality. However, there is only limited data on changes of renal function after AF catheter ablation and predictors thereof. This is the largest study analyzing the effects of atrial fibrillation catheter ablation on renal function and changes thereof in a contemporary population during mid-term follow-up. We found that lower baseline eGFR was associated with higher CHADS2 and CHA2DS2-VASc scores and that both scores were independently associated with eGFR changes after atrial fibrillation catheter ablation as were atrial fibrillation recurrences.

Medical Research: What are the main findings of the study? Dr. Ko: In this study, not only did we find that serum levels of interleukin (IL)-31 were significantly higher in hemodialysis patients with pruritus symptoms, but we also demonstrated a positive exposure-response relationship between IL-31 levels and visual analog scale (VAS) scores of pruritus intensity. We also noted an inverse correlation between the severity of pruritus and the dialysis dose assessed by Kt/V. (more…)

MedicalResearch.com Interview with: Prof. Chia-Huang Kao From the Graduate Institute of Clinical Medical Science Department of Radiation Oncology and Nuclear Medicine and PET Center Graduate Institute of Clinical Medical Science China Medical University Hospital, Taichung, Taiwan. Medical Research: What are the main findings of the study? Prof. Kao: Patients with chronic kidney disease (CKD) are at high risk for hypoglycemia; several factors are reported to contribute to hypoglycemia in these patients. However, most previous studies were limited by the relatively small number of patients with CKD included in the study by the exclusion of cases with CKD. In the present study, the incidence rate of hypoglycemia in patients with CKD was 4.5%, which is approximately twice the value noted in previous reports and multivariate analysis revealed a 2.53-fold increase in the risk of death for CKD patients with hypoglycemia after adjusting for related confounding factors including hypertension, hyperlipidemia, diabetes, and antidiabetic drugs.

Mallika L. Mendu, M.D. Division of Renal Medicine Brigham and Women’s Hospital Boston, MA 02115.MedicalResearch.com Interview with: Mallika L. Mendu, M.D. Division of Renal Medicine Brigham and Women’s Hospital Boston, MA 02115. Medical Research: What are the main findings of the study? Dr. Mendu: Our study found that implementation of a chronic kidney disease (CKD) checklist, a tool that succinctly and clearly outlines CKD management guidelines, in a primary care clinic improved adherence to a number of significant management guidelines. We conducted a prospective study during a one year period among 13 primary care providers, four of whom were assigned to use a CKD checklist incorporated into the electronic medical record during visits with patients with CKD. Patients whose providers utilized a CKD checklist had higher rates of adherence to annual albuminuria testing, parathyroid hormone testing, phosphate testing, achieving a hemoglobin A1c target<7, documentation of avoidance of nonsteroidal anti-inflammatory drugs, use of an angiotensin-converting enzyme inhibitor or angiotensin-receptor blocker and vaccination for annual influenza and 5-year pneumococcus.

Sim Division of Nephrology and Hypertension Kaiser Permanente Los Angeles Medical Center, Los Angeles, Medical Research: What are the main findings of the study? Dr. Sim: Among a large diverse population of treated hypertensive people, those who achieved systolic blood pressures (SBP) in the ranges of 130-139mm Hg had the lowest risk for death and end stage renal disease (kidney failure).  Not surprisingly, those with SBP above 139 had incrementally greater risk, but somewhat surprising was that those with SBP under 130 also had a greater risk for death and kidney failure.

Dr. John C. Lieske, MD Mayo Clinic, Rochester, MNMedicalResearch.com Interview with Dr. John C. Lieske, MD Mayo Clinic, Rochester, MN Medical Research: What are the main findings of the study? Dr. Lieske: We followed 11 women before, 6 and 12 months after Roux en Y gastric bypass surgery.  The patients successfully lost weight as mean BMI fell from 46 kg/m2 preoperatively to 28 kg/m2 postoperatively.   Mean serum creatinine did not significantly change from baseline (0.8 mg/dl) to 12 months (0.7 mg/dl).  Hence mean GFR estimated by the CKD-EPI equation (eGFR) did not significantly change from 84 ml/min/1.73 m2 (baseline) to 90 ml/min/1.73 m2 (12 months).  However, GFR measured by iothalamate clearance (mGFR) significantly decreased from 108 ml/min/1.73m2 (121 ml/min) to 85 ml/min/1.73 m2 (90 ml/min).

MedicalResearch.com Interview with: Jeremiah R. Brown, PhD MS Assistant Professor of Health Policy and Clinical Practic The Dartmouth Institute Lebanon, NHMedicalResearch.com Interview with: Jeremiah R. Brown, PhD MS Assistant Professor of Health Policy and Clinical Practic The Dartmouth Institute Lebanon, NH   Medical Research: What are the main findings of the study? Dr. Brown: Using simple team-based quality improvement methods we prevented kidney injury in 20% of patients having a procedure in the cardiac catheterization lab.  Among patients with pre-existing kidney disease, we prevent kidney injury in 30% of patients. We believed that using a team-based approach and having teams at different medical centers in northern New England learn from one-another to provide the best care possible for their patients.  Some of the most innovative ideas came from these teams and identified simple solutions to protect patients from kidney injury from the contrast dye exposure; these included:
  • Getting patients to self-hydrate with water before the procedure (8 glasses of water before and after the procedure),
  • Allow patient to drink fluids up to 2-hours before the procedure (whereas before they were "NPO" for up to 12 hours and came in dehydrated),
  • Training the doctors to use less contrast in the procedure (which is good for the patient and saves the hospital money),
  • and creating stops in the system to delay a procedure if that patient had not received enough oral or IV fluids before the case (rather, they would delay the case until the patient received adequate fluids).Our success was really about hospital teams talking and innovating with one another instead of competing in the health care market, which resulted in simple, homegrown, easy to do solutions that improved patient safety.

MedicalResearch.com Interview with: Petter Bjornstad, M.D. Children's Hospital Colorado University of Colorado Denver Aurora, CO 80045 Medical Research: What are the main findings of the study? Dr. Bjornstad: Type 2 diabetes is the most common cause of end-stage renal disease in the Western world. It is therefore of paramount importance to develop a better understanding of the determinants of diabetic nephropathy risk and progression, to improve outcome in adolescents with type 2 diabetes. We report high rates of microalbuminuria and renal hyperfiltration in adolescents with type 2 diabetes, which forecast early renal morbidity and mortality. In our observational study, insulin sensitivity measured by hyperinsulinemic-euglycemic clamp studies, rather than adiposity, blood pressure, lipid and glycemic control was associated with markers of renal health (albumin-to-creatinine ratio and estimated glomerular filtration rate).

Anemia, Author Interviews, Kidney Disease / 18.07.2014

MedicalResearch.com Interview with: Dennis J. Cotter President Medical Technology and Practice Patterns Institute, Inc. Bethesda, MD 20816 Medical Research: What are the main findings of the study? Answer: This is the first study to document anemia management practice patterns among predialysis CKD patients before and after publication of TREAT. Using a retrospective observational design based on a large US health plan database with over 1.2 million claims for predialysis CKD stage 3 and 4 patients, we report 4 main study findings. 1) For CKD stage 3 patients, the proportion prescribed ESA therapy declined from 17% pre-TREAT to 11% post-TREAT (a 38% decline) and for CKD stage 4 patients, from 34% to 27% (a 22% decline). 2) Prescribing of ESA therapy was declining even before TREAT, but the decline accelerated in the post-TREAT period. 3) ESA prescribing declined after TREAT regardless of anemia status; among patients with hemoglobin <10 g/dL, only 25% of stage 3 and 33% of stage 4 CKD were prescribed ESAs two years after TREAT, a notable 50% decline. 4) After adjusting for all covariates, the probability of prescribing ESAs was 35% less during a two year period after vs. before TREAT publication.

Dr. Kimmel: AKI (Acute Kidney Injury) and CKD (Chronic Kidney Disease), two syndromes approached separately in medical school  curricula  as well as in the clinical arena are inextricably intertwined.  They should be taught as a combined entity, culminating in progressive loss of renal function necessitating renal replacement therapy (dialysis or transplantation). The two syndromes increase risk for cardiovascular disease and diminished quality of life as well.  Preventive and therapeutic strategies should be directed at the combined entity. (more…)

MedicalResearch.com Interview with: Victoria A. Kumar, M.D. Internal Medicine/Nephrology Division of Nephrology Department of Internal Medicine Southern California Permanente Medical Group Los Angeles, California, USA Medical Research: What are the main findings of the study? Dr. Kumar: There was over a 2 fold increase in patient survival in incident peritoneal dialysis patients in the first year on dialysis compared to propensity matched incident hemodialysis patients.  We excluded any patients who utilized a central dialysis catheter at any point during the first 90 days on hemodialysis in an effort to reduce the mortality bias associated with hemodialysis patients who start with a catheter.  All hemodialysis patients had pre-dialysis care by a nephrologist prior to starting dialysis. The 2+ fold increase in survival among peritoneal dialysis patients resulted in a 2-3 year cumulative survival advantage for peritoneal dialysis patients, using both intent to treat and as-treated analyses.

Dr. Paolo Fiorina, MD PhD Assistant Professor, Division of Nephrology, Harvard Medical SchoolMedicalResearch.com Interview with: Dr. Paolo Fiorina, MD PhD Assistant Professor, Division of Nephrology, Harvard Medical School and Dr. Roberto Bassi Post-doctoral research fellow Nephrology Department at Children's Hospital Boston. Dr. Roberto Bassi Post-doctoral research fellow Nephrology Department at Children's Hospital Boston.   MedicalResearch.com: What are the main findings of the study? Dr. Fiorina: It is common knowledge that type 2 diabetes is a worldwide epidemic and that diabetic nephropathy has become the leading cause of renal failure in the western world. One of the main drivers and worsening factors for the diabetic kidney disease is proteinuria associated with various degrees of tubular damage, and unfortunately, therapies to halt or prevent this complication are not available so far. Our findings show that B7-1 when expressed on podocytes (a specific subset of renal cells) determines alterations in podocytes function and morphology, predisposing individuals with T2D to the loss of proteins into the urine. We also demonstrate that Abatacept, an immunomodulatory drug currently employed for the treatment of a variety of autoimmune diseases, is able to specifically target this malignant pathway, preventing podocytes cellular alterations in vitro and proteinuria development in two murine models of diabetic nephropathy in vivo.

Answer: We chose this question because there is currently an important knowledge gap regarding safety and effectiveness of common drugs in individuals with chronic kidney disease. Because kidney dysfunction interferes with drug metabolism and drug elimination, patients with kidney dysfunction have traditionally been excluded from randomized controlled trials. Yet, practice guidelines are afterwards extrapolated to those in the absence of formal evaluation. (more…)

MedicalResearch.com Interview with: Eiji Ishimura, MD, PhD, FASN, FACP Osaka City University Hospital Professor,Department of Nephrology Osaka, JAPAN MedicalResearch.com: What are the main findings of the study? Dr. Ishimura: Poor glycemic control is a major factor in the overestimation of glomerular filtration rate (GFR) in diabetic patients. We found this simple conclusion by directly measuring GFR by use of inulin clearance. We have created new formulae to accurately assess the GFR in diabetic patients, with the correction of hemoglobin A1C (HbA1C) or glycated albumin (GA) as followings; 1)      eGFRcr corrected by HbA1c=eGFRcr / (0.428 + 0.085 × HbA1c) 2)      eGFRcr corrected by GA=eGFRcr / (0.525 + 0.028 × GA) (more…)

Dr Amitava Banerjee NIHR Clinical Lecturer in Cardiovascular Medicine University of Birmingham UK MedicalResearch.com Interview with: Dr Amitava Banerjee NIHR Clinical Lecturer in Cardiovascular Medicine University of Birmingham UK MedicalResearch.com: What are the main findings of the study? This was the first long-term study in individuals with atrial fibrillation to consider the impact of renal function, as measured by eGFR, on stroke/thromboembolism, mortality and bleeding in the same population concurrently. Answer: There were three main findings of our study.
  • First, patients with worsening renal function had more severe risk factor profiles and had higher rates of stroke/thromboembolism, mortality and bleeding.
  • Second, individuals receiving oral anticoagulation had lower rates of stroke/thromboembolism and mortality than those not receiving anticoagulation at all levels of renal function measured by eGFR, suggesting that anticoagulation has benefit in even patients with low eGFR.
  • Third, renal function was not an independent predictor of stroke/thromboembolism at 1 year after adjustment for baseline characteristics. (more…)

Frits R. Rosendaal PhD Department of Clinical Epidemiology Leiden University Medical Center, Leiden, The NetherlandsMedicalResearch.com Interview with: Frits R. Rosendaal PhD Department of Clinical Epidemiology Leiden University Medical Center, Leiden, The Netherlands MedicalResearch.com: What are the main findings of the study? Answer: In our study, we  found that moderately to severely decreased kidney function was associated with a 2.6-fold (95%CI 2.0-3.5) increased risk of venous thrombosis as compared with normal kidney function. Several hemostatic factors showed a procoagulant shift with decreasing kidney function, most notably factor VIII and von Willebrand factor. We showed that the increased risk of venous thrombosis in chronic kidney disease could not be explained by confounding factors such as body mass index, diabetes, hospitalization, or corticosteroid use. However, we found that factor VIII and von Willebrand factor fully explained the increased risk of venous thrombosis associated with impaired kidney function. (more…)

MedicalResearch.com Interview with: Yongjun Wang, MD Department of Neurology, Beijing Tiantan Hospital Capital Medical University, Beijing, China MedicalResearch.com: What are the main findings of the study? Answer: Our study demonstrated that reduced eGFR was independently associated with all-cause mortality and other post-stroke outcomes in type 2 diabetic patients; stroke subtype analysis in our cohort showed that this association was only evident in ischemic stroke and TIA. We also observed a U-shaped relationship between variation of eGFR and post-stroke outcomes, that is, increased odds ratios were seen among those with low and high levels of eGFR. The cutoff points of eGFR associated with poor outcomes of stroke were eGFR<45 ml/min/1.73m2 and≥ 120 ml/min/1.73m2, respectively. (more…)

Afshinnia, Farsad, M.D., M.S. Research Fellow and Clinical Lecturer Department of Nephrology University of Michigan Health System MedicalResearch.com: What are the main findings of the study? Answer: Spontaneous Renal Artery Dissection (SRAD) is most commonly observed in middle aged individuals. Although SRAD can have no association with other comorbidities at the time of presentation, we have noticed association with a number of systemic disorders such as hypertension, cancer, congestive heart failure, and rheumatologic diseases. In particular clustering of Fibromascular dysplasia (FMD), Ehlers-Danlos syndrome, poly arteritis nodosa, Poland syndrome, and nail patella syndrome in our patients has been striking. The most commonly observed presenting symptom is sudden onset severe flank pain which may be spontaneous or following physical stress. Other presenting features may include uncontrolled hypertension, groin and/or testicular pain, headache, nausea, vomiting, fever, dysuria, hematuria and blurry vision. (more…)

MedicalResearch.com Interview with: C Raina Elley C Raina Elley  Associate Professor and General Practitioner, Acting Head, Dept General Practice & Primary Health Care, Faculty Medical and Health Sciences, University of Auckland, Private Bag 92019, Auckland, New ZealandAssociate Professor and General Practitioner, Acting Head, Dept General Practice & Primary Health Care, Faculty Medical and Health Sciences, University of Auckland, Private Bag 92019, Auckland, New Zealand MedicalResearch.com: What are the main findings of the study? Answer: Type 2 Diabetes is the leading cause of end-stage renal failure and dialysis in many countries. Early identification of those who are at risk within primary care could prompt more intensive intervention to control glycaemia and blood pressure and use of ACE inhibitors or angiotensin receptor blockers to slow progression. Traditionally estimated glomerular filtration rate and/or urine albumin creatinine ratio have been used to alert clinicians of deteriorating renal function in people with diabetes. However, a far more accurate renal risk score has been developed that combines serum creatinine, demographic characteristics, albuminuria, glycaemia, blood pressure, cardiovascular co-morbidity and duration of diabetes. The 5-year renal risk score was developed by following more than 25,000 people with type 2 diabetes in New Zealand for a median of 7.3 years (equivalent to 180,497 person-years). The study identified those who commenced dialysis for end-stage renal disease, received a renal transplant or died from renal failure to derive the risk score. (more…)
