Summary
Hyperphosphatemia in chronic kidney disease (CKD) increases cardiovascular risk. Sevelamer, a novel phosphate binder, effectively controls phosphorus and may reduce calcification, offering an alternative to calcium-based binders.
Area of Science:
- Nephrology
- Cardiovascular Medicine
- Biochemistry
Context:
- Patients with chronic kidney disease (CKD) exhibit significantly increased cardiovascular mortality.
- Hyperphosphatemia is a prevalent and serious complication in advanced CKD.
- Traditional phosphate binders, like calcium carbonate, pose risks including increased calcium load and calcification.
Purpose:
- To evaluate sevelamer as a calcium-free, non-absorbed phosphate binder in CKD patients.
- To assess sevelamer's efficacy in controlling serum phosphorus levels.
- To explore sevelamer's potential benefits beyond phosphorus binding, such as reducing calcification and improving lipid profiles.
Summary:
- Sevelamer is a novel, non-absorbed, calcium-free, and metal-free phosphate binder.
- Clinical studies demonstrate sevelamer's effectiveness in managing hyperphosphatemia in CKD patients.
- Evidence suggests sevelamer may attenuate vascular calcification and positively influence lipid metabolism and inflammation.
Impact:
- Sevelamer offers a safer alternative to calcium-based binders for managing hyperphosphatemia in CKD.
- Potential reduction in cardiovascular and soft tissue calcification may improve patient outcomes.
- Further research into sevelamer's pleiotropic effects could lead to improved CKD management strategies.

Peritoneal dialysis, or PD, utilizes the peritoneal membrane as a filter to eliminate excess fluid and waste products. Effective nursing management is essential for ensuring patient safety, preventing complications, and promoting optimal function of the peritoneal dialysis process.Assessment and MonitoringNurses must thoroughly assess the patient before, during, and after each dialysis session. Regular monitoring includes vital signs, daily weight, fluid intake and output, and laboratory values...
01:30Urinary 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)...
01:28Chronic 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...
01:22Phosphate Buffer
The phosphate buffer system is a critical biological mechanism for maintaining pH stability in the body. This system operates primarily through two components: sodium dihydrogen phosphate (NaH2PO4), which acts as a weak acid, and sodium hydrogen phosphate (Na2HPO4), which serves as a weak base.
Sodium dihydrogen phosphate does not fully dissociate in neutral or acidic solutions. When a strong base, such as sodium hydroxide (NaOH), is introduced into the solution, sodium dihydrogen phosphate...

01:27Roles of Electrolytes: Calcium and Phosphate
Calcium and phosphate are essential electrolytes in the human body, with calcium being the most abundant mineral. Around 99% of the body's calcium is stored in the skeleton and teeth, forming a crystal lattice of mineral salts in combination with phosphates. Calcium plays crucial roles in various bodily functions such as blood clotting, neurotransmitter release, muscle tone maintenance, and nervous and muscle tissue excitability.

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,...
