INTRODUCTION: Proteinuria is a modifiable risk factor for chronic kidney disease (CKD) progression in children. Finerenone, a selective, non-steroidal, mineralocorticoid receptor antagonist (MRA) has been approved to treat adults with CKD associated with type 2 diabetes mellitus (T2DM) following results from the phase III clinical trials FIDELIO-DKD (NCT02540993) and FIGARO-DKD (NCT02545049). In a pre-specified pooled analysis of both studies (N = 13,026), finerenone was shown to have an acceptable safety profile and was efficacious in decreasing the risk of adverse kidney and cardiovascular outcomes and of proteinuria.

OBJECTIVE: FIONA and the associated open-label extension (OLE) study aim to demonstrate that …

Baclofen Induced Excessive Perspiration; A Case Report, Othman Farahneh, Lois C. Akpati, Miguel Alvarez Silva

Research Symposium

This case report highlights an unexpected side effect of Baclofen, a well-known medication, excessive sweating, a rare occurrence not typically associated with the drug. The patient, a 63-year-old woman, experienced persistent sweating despite initial attributions to postmenopausal symptoms and subsequent medication adjustments. Extensive testing revealed an association between Baclofen use and the symptoms, which resolved upon discontinuation of the drug.

The significance of this case lies in drawing attention to the underreported side effects of excessive sweating linked to Baclofen, emphasizing the importance of considering medication-related effects even with established drugs. The report urges increased awareness among healthcare professionals, addressing …

A Case Of Siadh After Bowel Preparation For Routine Colonoscopy, Joseph C. Rath, Allison M. Hemmer, Kennedy A. Forest, Kahlen R. Morris, Mary E. Watson

Aesculapius Journal (Health Sciences & Medicine)

Electrolyte abnormalities, including hyponatremia, are a known outcome of bowel preparations used for colonoscopy. Severe and symptomatic hyponatremia after bowel preparation is uncommon and occurs due to excessive release of ADH among other contributing factors. Risk factors for developing hyponatremia after bowel preparation include increased age, female gender, kidney disease, heart failure, and use of various medications. We present the case of a 78-year-old female who presented with altered mental status and possible seizures after completing bowel preparation with polyethylene glycol for a colonoscopy. Serum and urine studies were consistent with SIADH. She required fluid restriction, hypertonic saline, and sodium …

Introduction The aetiology of bacterial vaginosis (BV), a biofilm-associated vaginal infection, remains unknown. Epidemiologic data suggest that it is sexually transmitted. BV is characterised by loss of lactic acid-producing lactobacilli and an increase in facultative and strict anaerobic bacteria. Gardnerella spp are present in 95%–100% of cases; Gardnerella vaginalis has been found to be more virulent than other BV-associated bacteria (BVAB) in vitro. However, G. vaginalis is found in women with normal vaginal microbiota and colonisation is not sufficient for BV development. We hypothesise that Gardnerella spp initiate BV biofilm formation, but incident BV (iBV) requires incorporation of other key …

A Case Of Occlusive Myocardial Infarction Caused By Nephrotic Syndrome In A 26-Year-Old Type 1 Diabetic, Kyle Admire, Charlotta Jornlid, Chelsea Ryan, Rebecca Pauly

Marshall Journal of Medicine

Nephrotic syndrome is a rare condition distinguished by proteinuria exceeding 3g per day. Other associated characteristics include hematuria, hypoalbuminemia, edema, and hyperlipidemia. There is an array of complications of this syndrome, which are primarily due to the profound losses of protein in the urine. One such complication is thromboembolism, with most documented cases in the form of venous thromboembolism of the extremities which is in part due to urinary loss of antithrombin III and increased synthesis of prothrombotic factors. There are limited available data regarding arterial thrombi and especially few reports about coronary thromboses, which can be life-threatening. In this …

Improving Nutritional Delivery To Pediatric Patients On Continuous Renal Replacement Therapy, Jennifer Ruiz-Boada, Sarah Brunner, Tara Benton, Vimal Chadha

Presentations

INTRODUCTION: Continuous renal replacement therapy (CRRT) is used in critically ill children with acute renal failure. CRRT can lead to malnutrition by removing essential proteins and micronutrients. Malnutrition is associated with worse outcomes, including increased length of stay and mortality. CRRT guidelines suggest the importance of early nutrition and ensuring high protein intake. After evaluating our CRRT patients, we found sub-optimal adherence to the guidelines. This Quality Improvement project aimed to increase the percentage of patients achieving 75% of their goal protein and caloric intake by day 5 of CRRT initiation by 15% by August 2023. METHODS: A multidisciplinary group …

Results obtained from rat studies indicate that, even at low concentrations, mercurial species cause harmful effects on the kidneys, by inducing the nephrotic oxidative stress response. In the present work, Hg-associated proteins were identified as possible mercury-exposure biomarkers in rat kidneys exposed to low mercury chloride concentrations for 30 days (Hg-30) and 60 days (Hg-60), using metalloproteomic strategies. The renal proteomic profile was fractioned by two-dimensional electrophoresis and the mercury determinations in kidney samples, protein pellets and protein spots were performed using graphite furnace atomic absorption spectrometry. The characterization of Hg-associated protein spots and the analysis of differentially expressed proteins …

Ryan, Saran Lotfollahzadeh, Janice Weinberg, Alik Farber, Rajendran Vivendhan, Jean Francis, Nathanael Fillmore, Najia Idrees

Journal of Health Disparities Research and Practice

In the United States, significant racial and ethnic disparities exist in chronic kidney disease (CKD) and its management. Hemodialysis constitutes the main stay of renal replacement therapy for end-stage kidney disease (ESKD), which is initiated using central venous catheters (CVC) in most CKD patients in the United States. Black ESKD patients have higher usage and greater time on CVC for hemodialysis compared to White patients. This trend places Black patients at a potentially higher risk for CVC-related complications such as central venous stenosis (CVS). We posited that Black patients would have a higher prevalence and a greater risk of CVS. …

Research Colloquium

Background: Non-invasive ultrasound evaluation is part of the preoperative evaluation of patients needing creation of arteriovenous access. This study requires patients to return for an additional visit for imaging or visit an outpatient imaging facility. These visits produce delays in surgery and increase costs in healthcare. Point of care ultrasound examination at the same time of initial physician visit, allows to decrease cost, improvement of anatomical planning, and decrease timing of surgery.

Methods: We reviewed the UTRGV Vascular Surgery Database from January to December 2020, for patients who has elective outpatient arteriovenous access creation, in which has pre-operative evaluation with …

Proton-Pump Inhibitors Related Acute Interstitial Nephritis. A Case Report, Mery B. Bartl, Reham Majzoub

Research Colloquium

Background: Acute Interstitial nephritis is a common and reversible cause of Acute Kidney Injury, accounting for 15-27% of renal biopsies performed because of this condition. Its incidence has been increasing worldwide. By and large, drug-induced AIN is currently the most common etiology, with antimicrobials and nonsteroidal anti-inflammatory drugs being the most frequent offending agents. The hallmark pathologic features are interstitial edema, interstitial inflammation, and tubulitis with a predominance of CD4+ T lymphocytes and mononuclear cells, with variable numbers of eosinophils. Patients with AIN typically present with nonspecific symptoms of acute renal failure, including oliguria, malaise, anorexia, nausea, and vomiting and …

Penile Calciphylaxis In An End Stage Renal Disease Patient., Juan Enrique Garcia Lopez, Alain Velazquez Blanco, Aileen Aguilar, Sareena Siyas, Daniel Ibarias Paz, Mays Abdulazeez, Jesus Garza-Tamez, Desmond Adamu

Research Colloquium

Background: Penile Calciphylaxis occurs in about 1–4% of hemodialysis patients worldwide. Associated mortality rates are very high, and hyperparathyroidism is the second most frequently associated disorder. Addressing the resulting metabolic imbalance, and surgical intervention guided by findings of radiological studies may improve quality of life. The pathogenesis is thought to be mediated by vascular smooth muscle cells which differentiate into osteoblast-like cells. Decrease in vascular calcification inhibitory proteins fetuin-A and matrix Gla is found in patients on dialysis causing systemic medial calcification of arterioles, leading to epidermal ischemia, tissue infarction, and ulceration.
