Hyponatremia in a Patient With Vasodilatory Shock Due to Overdose of Antihypertensive Medications: A Case Report.

Vasodilatory shock can be caused by septic shock, neurogenic shock, anaphylaxis, drugs, and toxins. Vasopressin is commonly used for the restoration of vasomotor tone in vasodilatory shock due to sepsis. This agent exerts its vasoconstrictive effect via smooth muscle V1 receptors and has antidiuretic activity via kidney V2 receptors.

Using herbs medically without knowing their composition: are we playing Russian roulette?

Herbal medicine, a form of complementary and alternative medicine (CAM), is used throughout the world, in both developing and developed countries. The ingredients in herbal medicines are not standardized by any regulatory agency. Variability exists in the ingredients as well as in their concentrations.

Pentoxifylline in diabetic kidney disease (VA PTXRx): protocol for a pragmatic randomised controlled trial.

Introduction: Diabetic kidney disease (DKD) is the most frequent cause of end-stage renal disease (ESRD) in the USA and worldwide. Recent experimental and clinical data suggest that the non-specific phosphodiesterase inhibitor pentoxifylline (PTX) may decrease progression of chronic kidney disease. However, a large-scale randomised clinical trial is needed to determine whether PTX can reduce ESRD and death in DKD.

Acute Kidney Injury Associated With Semaglutide.

Case reports of acute kidney injury in patients taking the glucagon-like peptide 1 (GLP-1) receptor agonists exenatide and liraglutide have been reported. We report 2 patients with chronic kidney disease due to diabetic kidney disease who experienced rapid worsening of kidney function and increased proteinuria after being prescribed the GLP-1 receptor agonist semaglutide. In 1 patient, kidney biopsy showed advanced diffuse and nodular glomerulosclerosis accompanied by interstitial lymphoplasmacytic and eosinophilic infiltrate and evidence of acute tubular injury.

Proton-pump inhibitors associated with decreased urinary citrate excretion.

Introduction: Proton-pump inhibitors (PPIs) may increase the risk of kidney stone formation, but the mechanism has not been elucidated. There is a paucity of literature evaluating the effects of PPIs on urinary metabolites and urine pH.

Methods: We performed a retrospective review of nephrolithiasis patients treated at our institution and compared patients who were taking PPIs to those who were not at the time of their 24-h urine collections.

Targeting Inflammation in Diabetic Kidney Disease: Is There a Role for Pentoxifylline?

Diabetic kidney disease (DKD) is the most common cause of ESKD in the United States and worldwide. Current treatment for DKD includes strict glycemic control and normalization of BP with renin-angiotensin-aldosterone system (RAAS) blockade. Although RAAS blockers slow progression of disease, they do not generally prevent ESKD and none of the studies with these agents in DKD included patients who were nonproteinuric, which make up an increasingly large percentage of patients with diabetes now seen in clinical practice.

Low statin use in nondialysis-dependent chronic kidney disease in the absence of clinical atherosclerotic cardiovascular disease or diabetes.

Background: Both reduced glomerular filtration rate and increased urine albumin excretion, markers of chronic kidney disease (CKD), are associated with increased risk of atherosclerotic cardiovascular disease (ASCVD). However, CKD is not recognized as an ASCVD risk equivalent by most lipid guidelines. Statin medications, especially when combined with ezetimibe, significantly reduce ASCVD risk in patients with nondialysis-dependent CKD.

Statin use among Veterans with dialysis-dependent chronic kidney disease.

Introduction: The benefits of statin medications in patients receiving maintenance dialysis remains controversial and clinical trials overall have shown no benefit. Potential side effects of statin medications include myalgias, myopathy, and memory loss and risk of side effects associated with statin medications increase with higher statin doses. We examined statin use and statin dose among Veterans with dialysis dependent CKD.

Diversity of the midstream urine microbiome in adults with chronic kidney disease.

Purpose: To examine the characteristics of the midstream urine microbiome in adults with stage 3-5 non-dialysis-dependent chronic kidney disease (CKD).

Methods: Patients with non-dialysis-dependent CKD (estimated glomerular filtration rate [eGFR] < 60 ml/min/1.73 m) and diuretic use were recruited from outpatient nephrology clinics.

Renal Replacement Therapy and Incremental Hemodialysis for Veterans with Advanced Chronic Kidney Disease.

Each year approximately 13,000 Veterans transition to maintenance dialysis, mostly in the traditional form of thrice-weekly hemodialysis from the start. Among >6000 dialysis units nationwide, there are currently approximately 70 Veterans Affairs (VA) dialysis centers. Given this number of VA dialysis centers and their limited capacity, only 10% of all incident dialysis Veterans initiate treatment in a VA center.

Non-dialysis dependent chronic kidney disease is associated with high total and out-of-pocket healthcare expenditures.

Background: Previous studies have documented the high costs of non-dialysis dependent chronic kidney disease (CKD) but out-of-pocket healthcare expenditures remain poorly explored. This study described total direct and out-of-pocket expenditures for adults with non-dialysis dependent CKD and compared expenditures with those for cancer or stroke.

Methods: This study used data from the 2011-2013 Medical Expenditure Panel Survey, a national survey of healthcare expenditures in the U.

Structured Exercise in Obese Diabetic Patients with Chronic Kidney Disease: A Randomized Controlled Trial.

Background: Patients with type 2 diabetes mellitus (DM), obesity, and chronic kidney disease (CKD) are generally physically inactive and may benefit from exercise. Our objective was to determine the effects of structured exercise on physical fitness, kidney function, endothelial function, inflammation, and body composition in such patients.

Methods: In this randomized, controlled trial, 36 male patients (age 49-81) were randomly assigned to exercise + diet management (n = 18) or diet alone (n = 18).

Urinary incontinence and diuretic avoidance among adults with chronic kidney disease.

Purpose: Diuretics remain an important medication for hypertension management among adults with chronic kidney disease (CKD), but diuretics may also worsen urinary symptoms, especially urinary incontinence (UI). This single-center pilot study examined the prevalence of UI among adults age ≥60 years with CKD using diuretics and assessed diuretic avoidance due to urinary symptoms.

Methods: Patients with non-dialysis-dependent CKD (estimated glomerular filtration rate <60 ml/min/1.

Selecting SNPs informative for African, American Indian and European Ancestry: application to the Family Investigation of Nephropathy and Diabetes (FIND).

Background: The presence of population structure in a sample may confound the search for important genetic loci associated with disease. Our four samples in the Family Investigation of Nephropathy and Diabetes (FIND), European Americans, Mexican Americans, African Americans, and American Indians are part of a genome- wide association study in which population structure might be particularly important. We therefore decided to study in detail one component of this, individual genetic ancestry (IGA).

Teaching renal physiology in the 21st century: focus on acid-base physiology.

A thorough understanding of renal physiology, and in particular acid-base physiology, is essential for an understanding of nephrology. Difficulties in both teaching and learning this material are major impediments to attracting medical trainees into nephrology. Approaches to teaching renal physiology include collaborative learning, computer-based learning and laboratory-based learning.

Pentoxifylline for Diabetic Nephropathy: an Important Opportunity to Re-purpose an Old Drug?

Diabetic nephropathy, or diabetic kidney disease (DKD), is the most serious complication of diabetes mellitus (DM). Despite recent advances in therapy, DKD still often progresses to end-stage renal disease (ESRD). Recent studies have suggested that pentoxifylline (PTX) may be efficacious in the treatment of DKD.

BP and Renal Outcomes in Diabetic Kidney Disease: The Veterans Affairs Nephropathy in Diabetes Trial.

Background And Objectives: Proteinuric diabetic kidney disease frequently progresses to ESRD. Control of BP delays progression, but the optimal BP to improve outcomes remains unclear. The objective of this analysis was to evaluate the relationship between BP and renal outcomes in proteinuric diabetic kidney disease.

Genome-Wide Association and Trans-ethnic Meta-Analysis for Advanced Diabetic Kidney Disease: Family Investigation of Nephropathy and Diabetes (FIND).

Diabetic kidney disease (DKD) is the most common etiology of chronic kidney disease (CKD) in the industrialized world and accounts for much of the excess mortality in patients with diabetes mellitus. Approximately 45% of U.S.

Magnesium and Dialysis: The Neglected Cation.

Disorders of magnesium homeostasis are very common in dialysis patients but have received scant attention. In this review, we address measurement of plasma magnesium, magnesium balance and the factors that affect magnesium flux during dialysis, the prevalence of hypo- and hypermagnesemia in dialysis patients, and the potential clinical significance of hypo- and hypermagnesemia in dialysis patients. Many factors can affect plasma magnesium concentration, including diet, nutritional status (including plasma albumin level), medications (such as proton pump inhibitors), and dialysis prescription.

Hypomagnesemia in hemodialysis patients: role of proton pump inhibitors.

Background: Recent observations have associated hypomagnesemia with increased risk of cardiovascular morbidity and mortality in hemodialysis patients.

Methods: We did a 3-month chart review of 62 chronic hemodialysis patients at a single US hospital. All were dialyzed using a dialysate [Mg] of 0.

Combined angiotensin inhibition for the treatment of diabetic nephropathy.

Combination therapy with angiotensin-converting-enzyme (ACE) inhibitors and angiotensin-receptor blockers (ARBs) decreases proteinuria; however, its safety and effect on the progression of kidney disease are uncertain. Methods We provided losartan (at a dose of 100 mg per day) to patients with type 2 diabetes, a urinary albumin-to-creatinine ratio (with albumin measured in milligrams and creatinine measured in grams) of at least 300, and an estimated glomerular filtration rate (GFR) of 30.0 to 89.

Life-threatening hypokalemia following rapid correction of respiratory acidosis.

A 56-year-old woman with a history of paraplegia and chronic pain due to neuromyelitis optica (Devic's syndrome) was admitted to a spinal cord injury unit for management of a sacral decubitus ulcer. During the hospitalization, she required emergency transfer to the intensive care unit (ICU) because of progressive deterioration of respiratory muscle function, severe respiratory acidosis, obtundation and hypotension. Upon transfer to the ICU, arterial blood gas revealed severe acute-on-chronic respiratory acidosis (pH 7.
