Insights

Routine uric acid testing in pregnancies with hypertensive disorders is not recommended. Evidence shows it lacks a definitive role in predicting, diagnosing, or managing pre-eclampsia, and stopping this practice offers significant cost savings.

Area of Science:

  • Obstetrics and Gynecology
  • Clinical Chemistry

Background:

  • Uric acid has been historically associated with pre-eclampsia pathophysiology.
  • It has been routinely tested for nearly a century in pregnancies with hypertensive disorders.

Purpose of the Study:

  • To evaluate the definitive role of uric acid testing in the prediction, diagnosis, and management of pre-eclampsia.
  • To argue against the routine use of uric acid testing in hypertensive pregnancies.

Main Methods:

  • Review of existing evidence on uric acid's role in pre-eclampsia.
  • Clinical and economic analysis of routine uric acid testing.

Main Results:

  • Current evidence suggests uric acid testing has no definitive role in pre-eclampsia.
  • Routine testing represents a potentially fruitless academic exercise.

Conclusions:

  • Routine uric acid testing should cease in pregnancies complicated by hypertension.
  • Discontinuing routine testing will lead to significant cost savings for health services.

Nephrotic Syndrome II : Assessment and Medical Management

IntroductionNephrotic syndrome is a kidney disorder marked by excessive protein loss in the urine, leading to various systemic complications. This condition often results from damage to the glomeruli—the kidney's filtering units—causing proteinuria, low blood protein levels, and fluid retention. Understanding the assessment, diagnosis, and management of nephrotic syndrome is essential for effective treatment and prevention of further kidney damage.AssessmentPatient History: Document...

Urinary Tract Calculi III: Medical Management

The diagnosis of renal calculi involves several imaging techniques, including non-contrast CT scans and ultrasound. These methods help visualize kidney stones, assess their size and location, and detect possible obstructions. Additionally, Measuring urine pH is useful for diagnosing specific stone types, such as struvite (alkaline pH) and uric acid stones (acidic pH). Cystine stones are primarily linked to cystinuria, a genetic condition. A urinalysis helps detect blood in the urine (hematuria)...

AssessmentSubjective Data: Obtain a detailed health history, including any recent or chronic urinary tract infections, periods of immobilization, previous episodes of renal calculi, and medical conditions such as gout, benign prostatic hyperplasia, or hyperparathyroidism. Review the medication history for drugs that may influence stone formation, including allopurinol, analgesics, loop diuretics, or thiazide diuretics. Document the use of long-term indwelling catheters and any past surgical...

Urinary Tract Calculi IV: Nutrition Therapy and Prevention

Management of renal calculi focuses on effective strategies like tailored nutrition and hydration therapy. Adjusting diet and fluid intake reduces stone formation and recurrence, making these interventions simple yet powerful in kidney stone prevention and management.Understanding Kidney StonesKidney stones form when calcium, oxalate, uric acid, and cystine concentrate and crystallize in urine. Factors contributing to their formation include genetic predisposition, certain medical conditions,...

Chronic Kidney Disease III: Interprofessional Care

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...
