Kidney Size Assessment in Children with Severe Acute Malnutrition Under 5 Years of Age: A Comparative Stud Kidney Size in Severe Acute Malnutrition
Journal of Pediatric Nephrology,
Vol. 9 No. 3 (2021),
Background and Aim: Malnutrition is a common disorder worldwide. Growth of visceral organs is affected by various factors including nutrition. Kidney size is an important parameter to assess renal growth. Kidney size in malnourished children is not well studied. We compared kidney size between severe acute malnourished (SAM) and normal children.
Methods: This prospective case control study was carried out at a tertiary care center in North India. Children with SAM (n=124) were enrolled as cases and 86 age and sex matched healthy children were enrolled as controls. All children were subjected to anthropometric and sonographic kidney size measurement. Various renal size parameters were compared between cases and controls. Linear correlation coefficients of kidney dimensions with anthropometric parameters were derived. P-values <0.05 were considered significant.
Results: The kidney length was significantly lower in malnourished cases compared to healthy controls. There was no difference in renal width and combined kidney volume (CKV) between the two groups. However, renal depth, combined relative kidney volume, CKV/body height ratio, and CKV/BSA ratio were significantly higher in malnourished child compared to healthy controls. Kidney size parameters (kidney length, width, depth, CKV) had significant correlations with anthropometric measurements in both groups but the correlations were stronger in healthy controls compared to malnourished children.
Conclusion: Malnourished children had a significantly smaller kidney length. This point should be remembered while evaluating kidney size in these children to avoid unnecessary invasive investigations.
