Appropriate For Gestational Age

Groups of healthy, small-for-gestational age (SGA) and preterm appropriate-for-gestational age (AGA) infants were studied at birth, 1 month, 3 months, and 12 months of age. Serum thymic hormone (TH) activity was assayed, the number of T lymphocytes in the peripheral blood was counted, and in vitro lymphocyte stimulation responses to phytohemagglutinin (PHA) were evaluated. TH activity was decreased in 1-month-old SGA infants. T cells were reduced in all low birth weight infants; the number reverted to normal by 3 months of age in preterm AGA infants, whereas it remained low for at least 12 months in the SGA group. Lymphocyte stimulation response was decreased in low birth weight infants; the extent of depression paralleled reduction in T lymphocyte number. These observations indicate that cell-mediated immunity is impaired in low birth weight newborns and reduced TH activity may be one of the pathogenetic factors involved. Persistent depression of immunocompetence may underlie the increased susceptibility of SGA infants to infection-related morbidity and mortality.

Packed Red Blood Cells

Background: Extremely low birth weight (ELBW) infants often receive transfusions of packed red blood cells. Long-term outcomes of infants treated with liberal versus restricted transfusion criteria have been evaluated with conflicting results. Clinicians incorporate a reticulocyte count (RC) in their transfusion decisions. There is a lack of information on reference ranges for RCs in growing ELBW infants and whether infant’s chronologic age or corrected gestational age generates a specific trend in the RCs. Objective: Our aim was to evaluate the levels of RCs obtained from ELBW infants over the course of the initial hospitalization. Study Design: A retrospective chart review of ELBW infants treated in the neonatal intensive care unit and had RCs performed. We analyzed the RCs to observe trends based on the chronologic age and corrected gestational age. Results: A total of 738 RCs were analyzed. A positive trend in RCs that reached a peak at 32-34 weeks corrected gestational age and then experienced a downward trend was observed. Conclusions: Our report examines a very common hematologic test that is theoretically helpful but is in need of guidelines concerning the appropriate frequency of testing and its utility in making transfusion decisions in ELBW infants.
