Morphological Changes of Newborn Lymph Nodes in Late Neonatal Sepsis Period

In this study, newborn with sepsis from 8–28 days in the late neonatal period developed morphological changes specific to both primary and secondary immune responses, depending on the gestational period. Of these, the percentage of follicular hyperplasia was determined, followed by paracortical hyperplasia, sinus histiocytosis, stromal cell proliferation, mixed-type hyperplasia, and lymph node fattening.
