Manuscripts, Articles, Book Chapters and Other Papers

Nephron loss initiates compensatory hemodynamic and cellular effects on the remaining nephrons. Increases in single nephron glomerular filtration rate and tubular flow rate exert higher fluid shear stress (FSS) on tubules. In principal cell (PC) culture models FSS induces ERK, and ERK is implicated in the regulation of transepithelial sodium (Na) transport, as well as, proliferation. Thus, we hypothesize that high tubular flow and FSS mediate ERK activation in the cortical collecting duct (CCD) of solitary kidney which regulates amiloride sensitive Na transport and affects CCD cell number. Immunoblotting of whole kidney protein lysate was performed to determine phospho-ERK (pERK) …

Introduction
Rabbit antithymocyte globulin (rATG) dosing strategies for induction in pediatric kidney transplantation vary between centers. It is not known whether a lower rATG induction dose provides safe and effective immunosuppression compared with a “standard” higher dose.

Methods
We performed a retrospective multicenter study of all isolated first-time kidney transplant recipients < 21 years old who received rATG induction between 1 January 2010 and 31 December 2014 at 9 pediatric centers. An a priori cutoff of a 4.5-mg/kg cumulative rATG dose was used to identify low (≤ 4.5 mg/kg) and standard (> 4.5 mg/kg) exposure groups. Outcomes examined included 12 months posttransplant graft function (estimated glomerular filtration rate [eGFR]); the occurrence of acute rejection, donor-specific antibody (DSA), neutropenia, and viral infection …

Improving Hepatitis B Vaccination Rates In Nephrology Patients With Chronic Kidney Disease: A Qi Initiative, Jill Swanson

Nursing Posters

• Hepatitis B vaccination is an important health maintenance preventative measure for patients with chronic kidney disease (CKD)
• Prior to initiating dialysis, hepatitis B vaccination administration is proven to be more effective than waiting until patients begin dialysis treatments.
• Efficacy and immune response of the hepatitis B vaccine is greater when kidney function is greater
• To better improve hepatitis B vaccine administration among the CKD stage 4 population, education measures and Epic modifiers will be implemented to achieve change
• Nursing knowledge and hepatitis B vaccine administration will improve after implementation of these measures

Estimated Glomerular Filtration Rate And The Racial Multiplier: Clinical Implications And Current Attitudes, Brittney A. Spooner

Honors Theses and Capstones

Chronic kidney disease (CKD) is associated with high morbidity and mortality and has high and increasing incidence worldwide. CKD is characterized by a reduction in glomerular filtration rate (GFR), but as GFR is difficult to measure directly, estimated glomerular filtration rate (eGFR) equations have been created to measure serum creatinine levels as a function of GFR. Some eGFR equations contain a racial multiplier that increases the eGFR of black patients, causing a spurious increase in reported kidney function. This study included a literature search that collected information on the rationale behind the multipliers usage and a survey that gathered information …

INTRODUCTION: Alport syndrome is a rare genetic disorder that affects as many as 60,000 persons in the USA and a total of 103,000 persons (10,000) in the European Union [1, 2]. It is the second most common inherited cause of kidney failure and is characterized by progressive loss of kidney function that often leads to end-stage kidney disease. Currently, there are no approved disease-specific agents for therapeutic use. We designed a phase 3 study (CARDINAL; NCT03019185) to evaluate the safety, tolerability, and efficacy of bardoxolone methyl in patients with Alport syndrome.

METHODS: The CARDINAL phase 3 study is an international, …

Diagnosis Of Early Delayed Graft Function (Dgf) Using Timp-2*Igfpb-7 Product In Transplant Recipients: Preliminary Results, Russell Leong, Cassandra Rodd, Kellyann M. Gomes, Solomiia Savedchuk, Paul S. Kellerman

Conference Presentation Abstracts

Background: DGF is acute kidney injury (AKI) defined as need for dialysis within one week of renal transplant. AKI is defined by a change in serum creatinine (SCr), however early recognition is limited by delay in creatinine rise. Accurate early biomarkers may lead to prevention or treatment of established AKI. The product of two novel biomarkers of cell cycle arrest, tissue Inhibitor of metalloproteinase-2 (TIMP-2) and insulin-like growth factor binding protein (IGFBP-7) have shown promise in predicting AKI. In prior studies, TIMP-2*IGFPB-7 ≤0.3 had high negative predictive value, and ≥2 high positive predictive value for AKI. Aims - 1) Investigate …

A Patient With Combined Metformin-Induced Lactic Acidosis And Euglycemic Diabetic Ketoacidosis, Kamil Sardarli, Russell Leong, Inayat Gill, Sami S. Zarouk

Conference Presentation Abstracts

Introduction: Metformin is a small, non-protein-bound molecule that can cause lactic acidosis in 6 out of 100,000 patients with a mortality rate of 30-50%. Concurrent euglycemic diabetic ketoacidosis (DKA) from sodium-glucose co-transporter-2 (SGLT2) inhibitor has been reported in one case. We report a unique case of a patient with acute kidney injury (AKI) in the setting of metformin-induced lactic acidosis and osmotic diuresis due to euglycemic DKA complicated by celecoxib use. Case Description: A 66-year-old female with a past medical history of type 2 diabetes mellitus for 21 years on metformin 1000 mg twice daily and empagliflozin 25 mg daily …

A Rare Case Of C3 Glomerulonephritis Presenting As Pulmonary Renal Syndrome, Gerardo Mederos, Harsh Patel, Menalee Hapuarachchi, Machaiah Madhrira, Ranjit Nair, Dana Ciobanu

HCA Healthcare Journal of Medicine

C3 glomerulonephritis (C3GN) is a rare disease that falls under the umbrella of C3 glomerulopathy (C3G). Classic manifestations of C3G include acute renal failure, proteinuria, and hematuria. In some cases, extrarenal manifestations can include ocular drusen. Until recent reports, C3G manifesting with pulmonary symptoms has not been reported. In this report, we describe a patient that initially presented with hemoptysis and acute renal failure, eventually leading to a diagnosis of pulmonary renal syndrome. Renal biopsy showed C3GN. The patient’s symptoms improved with pulse dose steroids, plasmapheresis and mycophenolate mofetil. C3G presenting with pulmonary symptoms is rare. Further research is needed …

Earlier Palliative Care Referrals For Nephrology Patients, Jerold Cohen

Doctor of Nursing Practice (DNP) Projects

Palliative care prevents and relieves suffering through the early identification and treatment of pain and other symptoms, which can be physical, psychosocial, or spiritual (World Health Organization, 2018). It is usually considered a service provided to oncology patients and has positively impacted their treatment. However, it is not as common for many other diseases where the patient would benefit from palliative care involvement. Presently, if palliative care is offered to nephrology patients, it is after they have started dialysis and are having second thoughts whether to continue this treatment plan as it has either become less effective or is interfering …

Evidence Of Nickel And Other Trace Elements And Their Relationship To Clinical Findings In Acute Mesoamerican Nephropathy: A Case-Control Analysis, Rebecca S. B. Fischer, Jason M. Unrine, Chandan Vangala, Wayne T. Sanderson, Sreedhar Mandayam, Kristy O. Murray

Plant and Soil Sciences Faculty Publications

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. Toenails clippings from study participants were analyzed using inductively coupled plasma mass spectrometry. A case-control analysis was performed, and concentrations were also analyzed over participant characteristics and clinical parameters. Nickel (Ni) concentrations were significantly higher in toenails …

Comparison Of The Performance Of The Ncdr Cathpci Score And Mehran Score To Predict Acute Kidney Injury Post-Percutaneous Coronary Intervention, Michelle Nguyen, S. Mustajab Hasan, Steven Quach, Sai Guduru, Faisal Rahim, Aiham Albaeni, Khalid Abusaada

HCA Healthcare Journal of Medicine

Background: A comparison of acute kindney injury (AKI) post-percutaneous coronary intervention (PCI) prediction models is lacking. In this study, we aim to compare the National Cardiovascular Data Registry (NCDR) CathPCI score to the Mehran score in acute coronary syndrome (ACS) vs non-ACS patients.

Methods: We included patients who received PCI at our facility between July 2015 and December 2017. We excluded patients without a pre- and/or post-PCI serum creatinine, patients on dialysis at the time of PCI and patients with missing variables required to calculate the predictive scoring model. The primary outcome of this study was AKI post-PCI. Performance of …

Diabetes Mellitus Does Not Predict Discharge In Hospitalized Patients With Acute Pyelonephritis: A Study From Karachi, Pakistan, Syed Furrukh Omair, Fazal Ur Rehman, Imrana Amin, Syed Ahsan Ali, Bakhtawar J. Rind, Bilal Ahmed

Section of Nephrology

Introduction: The incidence of acute pyelonephritis (APN) in the diabetic population is comparatively higher and tends to be more complicated, with serious outcomes. Although complicated pyelonephritis (PN) needs hospital admission and intravenous antibiotics, the magnitude of hospital stay due to comorbidities is limited. This study's aim was to assess the impact of diabetes mellitus on length of hospital stay among patients with PN.
Methods: We did a retrospective data review of 520 randomly selected hospitalized patients of PN from March 2015 to December 2019 from a tertiary care center. Electronic medical records were used for identifying medical conditions through ICD-10 …

Incorporating Kidney Disease Measures Into Cardiovascular Risk Prediction: Development And Validation In 9 Million Adults From 72 Datasets, Kunihiro Matsushita, Simerjot K. Jassal, Yingying Sang, Shoshana H. Ballew, Morgan E. Grams, Aditya Surapaneni, Johan Arnlov, Nisha Bansal, Milica Bozic, Tazeen H. Jafar

Section of Nephrology

Background: Chronic kidney disease (CKD) measures (estimated glomerular filtration rate [eGFR] and albuminuria) are frequently assessed in clinical practice and improve the prediction of incident cardiovascular disease (CVD), yet most major clinical guidelines do not have a standardized approach for incorporating these measures into CVD risk prediction. "CKD Patch" is a validated method to calibrate and improve the predicted risk from established equations according to CKD measures.
Methods: Utilizing data from 4,143,535 adults from 35 datasets, we developed several "CKD Patches" incorporating eGFR and albuminuria, to enhance prediction of risk of atherosclerotic CVD (ASCVD) by the Pooled Cohort Equation (PCE) …

Elhassan, Mubarak I. Abdalla, Mahfooz A. Farooqui, Atif A. Mateen, Saleh Kaysi, Syed A. Alam, Saif A. Khan, Mohamed F. Elmuzaini, Mourad M. Alsabbagh, Abdulrahman R. Altheaby

School of Medicine Publications and Presentations

Muslim renal transplant recipients often ask their physicians if performing certain lifestyles or religious obligations may be harmful to their health. Permissibility as advised by an expert Muslim physician is considered as being religiously accepted. A cross-sectional, survey-based study was conducted enquiring what nephrologists would advise their transplant recipients to do, about some lifestyles and religious duties. Fifty-eight nephrologists responded to the survey. Of these, 77% routinely follow-up post-transplant patients; 34% were from Saudi Arabia, 18% from the USA, and 20% from Pakistan. Fifty-four percent of the respondents would let patients with stable graft function fast during Ramadan, while 20% …

Paroxysmal Nocturnal Hemoglobinuria: Pandora’S Box?, Mihnea Alexandru Găman, Iulia Ursuleac, Daniel Coriu

Journal of Mind and Medical Sciences

Introduction. Paroxysmal nocturnal hemoglobinuria (PNH) is an acquired non-malignant hematological disorder which affects the pluripotent hematopoietic stem cell. The cause of PNH development is the occurrence of somatic mutations in the phosphatidylinositol glycan-A gene which encodes a protein necessary for the biosynthesis of glycosylphosphatidylinositol anchors. The diagnosis of PNH requires the presence of signs of intravascular hemolysis, thrombosis, and (or) bone marrow failure. Case Report. We report the case of a 42-year-old female, diagnosed with PNH at the age of 27, whose evolution was initially characterized predominantly by hemolytic attacks and whose disease pattern evolved towards thromboembolic episodes …

Renal Proximal Tubular Nemo Plays A Critical Role In Ischemic Acute Kidney Injury, Sang Jun Han, Ryan M. Williams, Mihwa Kim, Daniel A. Heller, Vivette D'Agati, Marc Schmidt-Supprian, H. Thomas Lee

Publications and Research

We determined that renal proximal tubular (PT) NF-κB essential modulator (NEMO) plays a direct and critical role in ischemic acute kidney injury (AKI) using mice lacking renal PT NEMO and by targeted renal PT NEMO inhibition with mesoscale nanoparticle–encapsulated NEMO binding peptide (NBP MNP). We subjected renal PT NEMO–deficient mice, WT mice, and C57BL/6 mice to sham surgery or 30 minutes of renal ischemia and reperfusion (IR). C57BL/6 mice received NBP MNP or empty MNP before renal IR injury. Mice treated with NBP MNP and mice deficient in renal PT NEMO were protected against ischemic AKI, having decreased renal tubular …
