Summary
Children with chronic kidney disease (CKD) often experience poor growth due to growth hormone (GH) resistance. Recombinant GH (rGH) therapy can improve growth velocity in these children.
Area of Science:
- Pediatric Nephrology
- Endocrinology
- Growth Disorders
Background:
- Poor growth is a common and serious complication of chronic kidney disease (CKD) in children, impacting psychosocial development and adult health.
- Growth failure in CKD has multifactorial causes, including disruptions in the growth hormone (GH) and insulin-like growth factor-1 (IGF-1) axis.
- CKD is characterized by GH resistance, not GH deficiency, with several underlying mechanisms contributing to this resistance.
Purpose of the Study:
- To review the pathogenesis of growth failure in children with CKD.
- To discuss the effects of growth failure on children's development.
- To explore management strategies for growth failure in pediatric CKD patients.
Main Methods:
- Review of existing literature on growth failure in pediatric CKD.
- Analysis of the role of GH/IGF-1 axis dysfunction.
- Evaluation of recombinant GH (rGH) therapy efficacy and safety.
Main Results:
- Disordered GH and IGF-1 axis function are key contributors to poor growth in pediatric CKD.
- Recombinant GH (rGH) therapy is an effective and safe option to accelerate growth velocity in children with CKD.
- Despite proven benefits, rGH therapy is underutilized in this population due to practitioner and family hesitancy.
Conclusions:
- Growth failure in children with CKD is a complex issue requiring targeted management strategies.
- Understanding GH resistance is crucial for addressing poor growth in pediatric CKD.
- Increased awareness and acceptance of rGH therapy could improve growth outcomes for children with CKD.

01:25Chronic 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...
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...
01:24Chronic 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...
01:29Acute Kidney Injury III: Clinical Manifestations
Acute Kidney Injury (AKI) progresses through distinct clinical phases: the oliguric, diuretic, and recovery phases, each marked by unique manifestations and challenges.Oliguric Phase:The oliguric phase is the initial stage of AKI, typically lasting 10 to 14 days. This phase is marked by a significant reduction in urine output, usually less than 400 mL per day, indicating decreased kidney function. Fluid retention is a prominent feature, leading to symptoms such as edema, hypertension, and...
01:18Chronic Kidney Disease IV: Nursing Management
Nursing management is essential for preventing complications, maintaining stability, and improving patients' quality of life in chronic kidney disease (CKD). By using a structured approach, nurses help slow CKD progression and support effective patient care.1. Comprehensive patient assessmentEffective management begins with nurses reviewing the patient’s medical history, and identifying key risk factors like diabetes, hypertension, and nephrotoxic drug use. Nurses assess signs of fluid...
01:10Nephrons
The kidneys are intricate organs with millions of working units known as nephrons. Each nephron features two major structures: the renal corpuscle, which facilitates blood plasma filtration, and the renal tubule, which handles the glomerular filtrate. Blood supply is directly linked to the nephrons. The renal corpuscle consists of the glomerulus, a capillary network, and the Bowman's capsule, a double-walled epithelial structure that encases the glomerulus. The filtering of blood plasma happens...
