Insights

Hand grip strength (HGS) is a reliable tool for assessing muscle power and nutritional status in children with chronic kidney disease (CKD). This bedside assessment aids in diagnosing protein energy wasting in pediatric CKD patients.

Area of Science:

  • Pediatric Nephrology
  • Nutritional Assessment
  • Muscle Physiology

Background:

  • Protein energy wasting (PEW) and cachexia are significant concerns in children with chronic kidney disease (CKD).
  • Hand grip strength (HGS) is a validated measure of muscle power in adult CKD patients.
  • Data on the utility of HGS for assessing muscle status in pediatric CKD is lacking.

Purpose of the Study:

  • To evaluate the reliability of hand grip strength (HGS) as an indicator of muscle power.
  • To determine the usefulness of HGS in assessing the nutritional status of children with CKD.

Main Methods:

  • An observational cross-sectional study involving 73 children with CKD (45 with end-stage kidney disease on hemodialysis, 28 not on dialysis).
  • Nutritional status assessed via biochemical markers (serum albumin, cholesterol) and anthropometrics (height, BMI).
  • Body composition analyzed using a BCM device for lean tissue mass (LTM); muscle power measured by HGS.

Main Results:

  • 69.8% of pediatric CKD patients exhibited HGS below the 10th percentile for age and sex.
  • HGS was notably reduced in children with chronic renal insufficiency (CRI) and those with non-glomerular kidney disease causes.
  • A positive correlation was found between HGS and height, but not with LTM or serum albumin.

Conclusions:

  • Hand grip strength (HGS) serves as a dependable, accessible bedside tool for nutritional assessment in pediatric patients with chronic kidney disease (CKD).
  • HGS can aid in the early identification of muscle wasting and malnutrition in this vulnerable population.

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 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 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...

Chronic 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...

The Roles of Bacteria and Fungi in Plant Nutrition

Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.
