Immunological studies of newborn infants with hyperbilirubinemia. 1981

K C Hwang, and K H Hsieh, and J H Chen

In order to study the immunocompetence of severely jaundiced newborn infants and the possible role of infection in the pathogenesis of neonatal hyperbilirubinemia, 74 newborn infants with varying degree of jaundice were studied with respect to several immunological parameters. The results showed that neonates with total serum bilirubin more than 20 mg/dl had statistically significantly higher numbers of white blood cells (WBCs), band form granulocytes, polymorphonuclear leukocytes (PMNs) and monocytes with Fc and complement (C') receptors and elevated serum IgM than did those with lower serum bilirubin. It is therefore concluded: 1) There is no difference in immunocompetence between severely and mildly jaundiced newborn infants, 2) Infection may play some role(s) in the pathogenesis of neonatal hyperbilirubinemia and 3) Determinations of total WBCs, band form granulocytes, phagocytes with Fc and C' receptors and serum IgM level are of help in the diagnosis of infection in the newborn period.

UI MeSH Term Description Entries
D007136 Immunoglobulins Multi-subunit proteins which function in IMMUNITY. They are produced by B LYMPHOCYTES from the IMMUNOGLOBULIN GENES. They are comprised of two heavy (IMMUNOGLOBULIN HEAVY CHAINS) and two light chains (IMMUNOGLOBULIN LIGHT CHAINS) with additional ancillary polypeptide chains depending on their isoforms. The variety of isoforms include monomeric or polymeric forms, and transmembrane forms (B-CELL ANTIGEN RECEPTORS) or secreted forms (ANTIBODIES). They are divided by the amino acid sequence of their heavy chains into five classes (IMMUNOGLOBULIN A; IMMUNOGLOBULIN D; IMMUNOGLOBULIN E; IMMUNOGLOBULIN G; IMMUNOGLOBULIN M) and various subclasses.

D007567 Jaundice, Neonatal Yellow discoloration of the SKIN; MUCOUS MEMBRANE; and SCLERA in the NEWBORN. It is a sign of NEONATAL HYPERBILIRUBINEMIA. Most cases are transient self-limiting (PHYSIOLOGICAL NEONATAL JAUNDICE) occurring in the first week of life, but some can be a sign of pathological disorders, particularly LIVER DISEASES.

D008214 Lymphocytes White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS. Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell
