[The lipid profile in children with nephrosis]

Area of Science:

• Pediatric Nephrology
• Clinical Biochemistry
• Cardiovascular Risk Factors

Context:

• Severe Nephrotic Syndrome (SNI) with Low Glomerular Filtration Rate (LGM) is a complex condition.
• Understanding associated metabolic disturbances is crucial for comprehensive patient management.
• Serum lipid profiles are key indicators of metabolic health in pediatric populations.

Purpose:

• To quantify serum lipid levels in children diagnosed with SNI of LGM.
• To investigate the relationship between total cholesterol and specific lipid fractions (LBD, LAD, LMBD) and serum albumin.
• To identify the prevalence of dyslipidemia in this specific pediatric cohort.

Summary:

• All 25 children studied presented with total cholesterol and triglyceride levels exceeding the 95th percentile for age and sex.
• Elevated low-density lipoprotein cholesterol (LBD) was observed in 92% of patients, while 72% had low high-density lipoprotein cholesterol (LAD).
• A strong positive correlation was found between total cholesterol and LBD (r = +0.854), but not with LAD or serum albumin.

Impact:

• This study highlights a high prevalence of severe dyslipidemia in children with SNI of LGM.
• Findings underscore the need for monitoring and managing lipid abnormalities to mitigate potential cardiovascular risks in these patients.
• The direct relationship between total cholesterol and LBD emphasizes the atherogenic lipid profile common in this condition.
