Insights

Children with chronic kidney disease (CKD) on kidney replacement therapy (KRT) show improved final height due to better management. Early growth, especially by age two, is crucial for predicting final height in these children.

Area of Science:

  • Pediatric Nephrology
  • Growth and Development
  • Chronic Kidney Disease Management

Background:

  • Growth retardation is a significant complication for children with chronic kidney disease (CKD) requiring kidney replacement therapy (KRT).
  • Improved growth in childhood CKD correlates with better outcomes in morbidity and mortality.
  • Advances in conservative management, dialysis, immunosuppression, and transplantation have improved final height over time.

Purpose of the Study:

  • To analyze the relationship between early growth and final height in pediatric patients undergoing KRT.
  • To highlight the critical role of infancy and early childhood in determining final stature for children with CKD.

Main Methods:

  • Analysis of data from pediatric international registries, including the European Society for Paediatric Nephrology/European Renal Association-European Dialysis and Transplant Association (ESPN/ERA-EDTA) Registry.
  • Examination of growth patterns and final height outcomes in children on KRT.

Main Results:

  • Preliminary data confirms a significant association between final height and height attained at 2 years of age in children on KRT.
  • Infancy represents a critical period for linear growth, impacting final adult height.

Conclusions:

  • Early growth assessment, particularly by age two, is vital for predicting final height in children with CKD on KRT.
  • Continued improvements in CKD management contribute to better growth outcomes and final height in pediatric patients.

Kidney Transplant I: Introduction

A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...

Continuous Renal Replacement Therapy01:30

Continuous Renal Replacement Therapy

Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...

Kidney Transplant III: Nursing Management

Postoperative Nursing Management for Kidney Transplant PatientsPostoperative nursing management care includes monitoring the surgical site, encouraging early movement, and promoting lung health through breathing exercises. Nurses also administer prescribed medications like H2-blockers, such as famotidine, or proton pump inhibitors, like omeprazole, to help prevent gastrointestinal ulcers and bleeding. Fungal infections in the mouth and bladder can result from immunosuppressive and antibiotic...

Chronic Kidney Disease II: Clinical Manifestations

Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Chronic Kidney Disease I: Introduction01:25

Chronic Kidney Disease I: Introduction

Chronic Kidney Disease (CKD) arises when the kidneys progressively lose their ability to function, ultimately leading to end-stage renal disease. At this advanced stage, the kidneys can no longer filter waste or maintain essential body functions, requiring renal replacement therapy (RRT) through dialysis or a kidney transplant for survival.Early-stage chronic kidney disease and detection challengesIn CKD's early stages, symptoms often remain absent because healthy nephrons compensate for...

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...
