Faculty, Staff and Students Publications

PURPOSE OF REVIEW: Obesity is a risk factor for the development and progression of chronic kidney disease (CKD). In this review, we provide a comprehensive overview of various management options (lifestyle intervention, medications, and bariatric surgery) to address obesity in those with CKD.

RECENT FINDINGS: Few clinical trials have examined the benefits of lifestyle modifications in those with preexisting CKD and suggest potential renal and cardiovascular benefits in this population. Yet, superiority of different dietary regimen to facilitate weight loss in CKD is unclear. Although medications could offer short-term benefits and assist weight loss, their safety and long-term benefits warrant …

Retrospective Analysis Of Post-Operative Sepsis Rates, Stone Composition, And Ureteral Stent Duration After Ureteroscopy And Laser Lithotripsy During Covid-19, Young Son, Julia T. Scali, Ian Madison, Paul Chialastri, Thomas Mueller

Rowan-Virtua Research Day

Ureteroscopy with laser lithotripsy is routinely used to remove stones but results in manipulation of the genitourinary mucosa and has a well-established relationship with post-operative sepsis under certain conditions. Postoperative sepsis represents a significant morbidity and mortality cost to patients and the healthcare system. Several studies to determine risk factors for sepsis after ureteroscopy have been completed. Such risk factors include positive preoperative urine cultures, female gender, prolonged preoperative stent time > 1 month, and patients with sepsis at the time of initial stenting. To improve sepsis rates, procedural alterations such as the use of disposable ureteroscopes have been introduced, as …

Community Health Sciences

Introduction: The creatinine-based Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) estimated glomerular filtration rate (eGFR) equation was calibrated for the general Pakistan population (eGFRcr-PK) to eliminate bias and improve accuracy. Cystatin C-based CKD-EPI equations (eGFRcys and eGFRcr-cys) have not been assessed in this population, and non-GFR determinants of cystatin C are unknown.
Methods: We assessed eGFRcys, eGFRcr-cys, and non-GFR determinants of cystatin C in a cross-sectional study of 557 participants (≥40 years of age) from Pakistan. We compared bias (median difference in measured GFR [mGFR] and eGFR), precision (interquartile range [IQR] of differences), accuracy (percentage of eGFR within 30% of mGFR), …

Association Of Blood Pressure Variability And Diuretics With Cardiovascular Events In Patients With Chronic Kidney Disease Stages 1-5, L Parker Gregg, S Susan Hedayati, Hui Yang, Peter N Van Buren, Subhash Banerjee, Sankar D Navaneethan, Salim S Virani, Wolfgang C Winkelmayer, Carlos A Alvarez

Faculty, Staff and Students Publications

Visit-to-visit blood pressure variability (BPV) is associated with cardiovascular events in the general population. Data are scarce in chronic kidney disease (CKD). We hypothesized that BPV would be associated with cardiovascular outcomes, death, and end-stage kidney disease (ESKD) and that diuretics would modify these associations in patients with CKD.

We studied U.S. Veterans with non-dialysis CKD stages 1-5 and hypertension on non-diuretic antihypertensive monotherapy. At the time of second antihypertensive agent prescription, we propensity-matched for exposure to a loop or thiazide diuretic vs. any other antihypertensive. BPV was defined as the coefficient of variation of systolic blood pressure over …

Common Questions And Misconceptions About Creatine Supplementation: What Does The Scientific Evidence Really Show?, Jose Antonio, Darren G Candow, Scott C Forbes, Bruno Gualano, Andrew R Jagim, Richard B Kreider, Eric S Rawson, Abbie E Smith-Ryan, Trisha A Vandusseldorp, Darryn S Willoughby, Tim N Ziegenfuss

Faculty, Staff and Students Publications

Supplementing with creatine is very popular amongst athletes and exercising individuals for improving muscle mass, performance and recovery. Accumulating evidence also suggests that creatine supplementation produces a variety of beneficial effects in older and patient populations. Furthermore, evidence-based research shows that creatine supplementation is relatively well tolerated, especially at recommended dosages (i.e. 3-5 g/day or 0.1 g/kg of body mass/day). Although there are over 500 peer-refereed publications involving creatine supplementation, it is somewhat surprising that questions regarding the efficacy and safety of creatine still remain. These include, but are not limited to: 1. Does creatine lead to water retention? 2. …

Long-Term Dynamics Of The Kidney Disease Epidemic Among Hiv-Infected Individuals, Heather Gudaz, Henry A. Ogu, Elissa J. Schwartz

Spora: A Journal of Biomathematics

One of many risks facing HIV+ individuals is the development of kidney dysfunction and end stage kidney disease (ESKD). A differential equation-based mathematical model was developed to assess the impact of antiretroviral therapy on the progression to kidney disease and on reducing mortality due to kidney failure. Analytical and numerical predictions of long-term HIV+ ESKD prevalence show that therapy can lead to either extremely low levels of disease prevalence or increased prevalence, depending on drug efficacy levels and mechanisms of action. Maintenance of HIV+ ESKD prevalence below one individual is possible with sufficient efficacy (e.g., 99%) against the progression from …

Eosinophils are a myeloid cell subpopulation that mediates type 2 T helper cell immune responses. Unexpectedly, we identified a rapid accumulation of eosinophils in 22 human liver grafts after hepatic transplantation. In contrast, no eosinophils were detectable in healthy liver tissues before transplantation. Studies with two genetic mouse models of eosinophil deficiency and a mouse model of antibody-mediated eosinophil depletion revealed exacerbated liver injury after hepatic ischemia and reperfusion. Adoptive transfer of bone marrow-derived eosinophils normalized liver injury of eosinophil-deficient mice and reduced hepatic ischemia and reperfusion injury in wild-type mice. Mechanistic studies combining genetic and adoptive transfer approaches identified …

Mitochondrial Regulation Of Diabetic Kidney Disease, Daniel L Galvan, Koki Mise, Farhad R Danesh

Faculty, Staff and Students Publications

The role and nature of mitochondrial dysfunction in diabetic kidney disease (DKD) has been extensively studied. Yet, the molecular drivers of mitochondrial remodeling in DKD are poorly understood. Diabetic kidney cells exhibit a cascade of mitochondrial dysfunction ranging from changes in mitochondrial morphology to significant alterations in mitochondrial biogenesis, biosynthetic, bioenergetics and production of reactive oxygen species (ROS). How these changes individually or in aggregate contribute to progression of DKD remain to be fully elucidated. Nevertheless, because of the remarkable progress in our basic understanding of the role of mitochondrial biology and its dysfunction in DKD, there is great excitement …

Faculty, Staff and Students Publications

BACKGROUND: Heart failure (HF) after kidney transplantation is a significant but understudied problem. Pretransplant dialysis modality could influence incident HF risk through differing cardiac stressors. However, whether pretransplant dialysis modality is associated with the development of posttransplant HF is unknown.

METHODS: We used the US Renal Data System to assemble a cohort of 27,701 patients who underwent their first kidney transplant in the USA between the years 2005 and 2012 and who had Medicare fee-for-service coverage for >6 months preceding their transplant date. Patients with any HF diagnosis prior to transplant were excluded. Detailed baseline patient characteristics and comorbidities were …

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 …

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) …

Spitting Blood And Casts With Mud: A Rare And Unusual Presentation Of C3 Glomerulonephritis, Gerardo Mederos, Harsh Patel, Menalee Hapuarachchi, Som Aftabizadeh, Prashanth Reddy, Ranjit Nair, Dana Ciobanu, Machaiah Madhrira

Internal Medicine

C3 glomerulonephritis (C3GN) is a rare disease that falls under the umbrella of C3 glomerulopathy. It is manifested by abnormal activation of the alternate pathway resulting in complement deposition in the glomeruli. Kidney biopsy with characteristic findings of electron-dense deposits in the mesangial and capillary wall confirms the diagnosis. Until recently, C3GN presenting with primarily lung involvement had not been reported. We present a unique case of initial pulmonary manifestation C3GN.

Rowan-Virtua Research Day

Proper visualization of the surgical field during any procedure is one of the most imperative elements of surgery. The tools used to obtain this goal come with their own set of risks. This report describes a patient who developed postoperative acalculous cholecystitis (PAC) after use of a Nathan liver retractor. PAC is a rare complication of urologic surgery and is often more severe than acalculous cholecystitis (AC), leading to significant morbidity.

Chronic Renal Failure, But Why? A Case Report., Palak Patel, Michael Rothberg

Rowan-Virtua Research Day

Renal failure, both acute and chronic, can present from many different etiologies and if diagnosed with diabetes mellitus, it is commonly assumed to be due to diabetic nephropathy. Monoclonal gammopathy of renal significance (MGRS) is a disorder that combines monoclonal gammopathy of undetermined significance with end stage renal disease. Monoclonal immunoglobulins are secreted by B or plasma cells leading to deposition in the kidney causing end organ damage. Several different subtypes fall under this category of renal diseases including, but not limited to, amyloidosis, C3 glomeruopathy, and light chain proximal tubulopathy, or better known as Fanconi syndrome1. Fanconi syndrome, which …

A Case Of Atraumatic Posterior Thigh Compartment Syndrome, Nailah Mubin, Brian Katt

Rowan-Virtua Research Day

Compartment syndrome(CS) occurs when intra-compartmental pressures exceeds to a point where arterial, venous and lymphatic circulation of local tissues, muscles and nerves is compromised. CS is most common after a traumatic injury and usually occurs in the leg or forearm and less commonly in the thigh. Thigh compartment syndrome is rare due to its larger size and more compliant borders. We present a case of nontraumatic compartment syndrome in the posterior thigh associated with rhabdomyolysis and a sciatic nerve palsy which then required emergent fasciotomy. The patient's course was further complicated by acute renal failure due to the rhabdomyolysis and …

Novel Mechanisms And Biomarkers In Alcohol-Induced Organ Injury., Christine E. Dolin

Electronic Theses and Dissertations

Background. Ethanol (EtOH) consumption is known to affect multiple organs; this is unsurprising, as the concentration of EtOH in the blood at relevant doses reaches the millimolar range. The overarching goal of this dissertation was to elucidate mechanisms of alcohol-induced organ injury, specifically the effects of alcohol on the hepatic extracellular matrix (ECM) proteome, the alcoholic hepatitis (AH) plasma peptidome, and the effects of alcohol on the renal cortex proteome and transcriptome. Methods. Mice were pair-fed ethanol-containing liquid diet chronically, and then some mice were administered lipopolysaccharide (LPS). Liver sections from these mice were processed in a series of increasingly …

The Effect Of Antihypertensive Dosing On Hypertension In Children With Chronic Kidney Disease, Benjamin A. Matta, Uri S. Alon, Bradley Warady Md, Tarak Srivastava, Darcy Weidemann

Posters

Background

Hypertension (HTN) is a highly prevalent and major risk factor for poor cardiovascular and renal outcomes in chronic kidney disease (CKD). Previous research suggests that HTN is underdiagnosed and undertreated in children with CKD. To our knowledge no studies have investigated the effect of antihypertensive (antiHTN) dose on blood pressure (BP) control in this population.

Objective

To determine the effect of antiHTN dose on HTN status in children with CKD.

Methods

Study population: 255 participants studied in the Chronic Kidney Disease in Children (CKiD) study at their 3rd visit, taking at least 1 antiHTN drug.
