Glomerulosclerosis in the Sudden Infant Death Syndrome

Abstract

In the past two decades, two groups of investigators have alleged that infants who die of the sudden infant death syndrome (SIDS) have excess numbers of sclerotic glomeruli in their kidneys.

This double blind, case-control study was undertaken to test that assertion. Using microscopic sections of the kidney from 153 autopsies (99 SIDS infants and 54 control infants) in the National Institute of Child Health and Human Development (NICHD) Cooperative Epidemiologic Study of Risk Factors for SIDS, we counted relative numbers of sclerotic glomeruli in four fields of renal cortical tissue in two sections from each infant. Our results indicate that there is no difference between the two groups in regard to the proportion of sclerotic glomeruli.
