Immunoglobulin concentrations in human milk and gastric samples at 2 h postprandial time from paired mother-infant delivered prematurely (23–32 week of gestational age (GA), 7–98 days of postnatal age) and at term (38–40 week of GA, 16–42 days of postnatal age). Concentration of total IgA (SIgA/IgA) (A) in preterm infant samples and (B) in term infant samples; Concentration of total secretory component (SC/SIgA/SIgM) (C) in preterm infant samples and (D) in term infant samples. Values are mean ± SEM, n = 15 for preterm infants and n = 8 for term infants. Asterisks show statistical significant differences between variables (*** p < 0.001; * p < 0.05) using the Wilcoxon matched-pairs signed-rank test.
