Abstract

Insights

Microalbuminuria does not reliably predict cisplatin-induced kidney damage (azotemia) in dogs. This study found no association between microalbuminuria and azotemia in dogs receiving cisplatin chemotherapy.

Area of Science:

  • Veterinary Oncology
  • Nephrology
  • Pharmacology

Background:

  • Cisplatin is a vital chemotherapy drug for various cancers.
  • Renal toxicity is a significant limitation to cisplatin therapy.
  • Microalbuminuria is a potential indicator of kidney damage.

Purpose of the Study:

  • To investigate the association between microalbuminuria and cisplatin-induced azotemia in dogs.
  • To determine if microalbuminuria can serve as a predictive marker for kidney damage in dogs treated with cisplatin.

Main Methods:

  • Prospective observational study involving 32 client-owned dogs treated with cisplatin.
  • Azotemia defined as elevated serum creatinine post-cisplatin treatment.
  • Microalbuminuria and renal function tests monitored after each treatment.

Main Results:

  • Cisplatin-induced azotemia developed in 31% of dogs.
  • No significant difference in microalbuminuria prevalence between dogs with and without azotemia after the first three treatments.
  • Microalbuminuria was not found to be associated with azotemia.

Conclusions:

  • Microalbuminuria is an insensitive marker for detecting cisplatin-induced renal damage in dogs.
  • Routine testing for microalbuminuria is not recommended for monitoring cisplatin nephrotoxicity.
  • Further research may explore alternative biomarkers for early detection of kidney injury.

Diabetic Nephropathy

Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration occur due to afferent arteriolar...

Acute Kidney Injury IV: Diagnostic Studies and Prevention

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...

Acute Pyelonephritis II: Diagnostic Studies and Management

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

Urine Studies I: Urinalysis

Urinalysis is a widely used diagnostic test that analyzes urine's physical, chemical, and microscopic characteristics. Healthcare providers use it to detect and monitor various health conditions, including renal disease, urinary tract infections (UTIs), diabetes, and metabolic or systemic disorders.Components of UrinalysisUrinalysis consists of three primary components: physical, chemical, and microscopic examination. Each provides unique insights into the urine sample and, by extension, the...
