Summary
Intravenous iron effectively treats iron deficiency in hemodialysis patients, improving hemoglobin. However, its long-term safety and impact on patient-centered outcomes require further investigation.
Area of Science:
- Nephrology
- Hematology
- Clinical Pharmacology
Background:
- Iron deficiency is prevalent in advanced kidney disease, especially among hemodialysis patients.
- Intravenous iron is a standard treatment to correct iron deficiency, improving hemoglobin and reducing erythropoiesis-stimulating agent needs.
- The safety of intravenous iron concerning patient-centered outcomes remains insufficiently studied.
Purpose of the Study:
- To review the potential safety concerns and issues related to iron toxicity in patients receiving intravenous iron therapy.
- To critically evaluate existing evidence on the safety of intravenous iron in hemodialysis patients.
Main Methods:
- Review of existing literature and studies on intravenous iron therapy in kidney disease.
- Analysis of reported safety concerns and clinical relevance of studied endpoints.
Main Results:
- Established efficacy of intravenous iron in improving hemoglobin and reducing medication requirements.
- Identified potential safety concerns, though often based on small studies with unclear clinical relevance.
Conclusions:
- While intravenous iron is effective for iron deficiency in hemodialysis, comprehensive safety data regarding patient-centered outcomes is lacking.
- Further well-designed studies are needed to adequately assess the safety profile of intravenous iron therapy.

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

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...

Renal failure occurs when the kidneys lose their ability to filter waste products from the blood effectively. It can be classified into two types: acute renal failure (ARF) and chronic renal failure (CRF).
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...

2.2K
Dialysis is a diffusion-based purification process that separates analyte molecules from a complex matrix. This is accomplished by allowing molecules in the solution to pass through a semipermeable membrane into a liquid on the other side. The membrane is usually made of cellulose acetate or cellulose nitrate, and the second liquid must be miscible with the solution. Ions (e.g., chloride or sodium) or organic molecules (e.g., glucose) can pass through the membrane pores, which generally have...

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...

4.1K
Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...
