“…Although the monocytes of preterm infants have reduced cytokine production, there is similar efficiency in phagocytosis and intracellular killing of pathogens as that of term neonates [11,12]. Moreover, preterm neonates are deficient in the production of C1, C4 (classical pathway) and factor B (alternative pathway) as compared to term neonates [13].…”

“…У новорожден ных концентрации почти всех циркулирующих в сыво ротке крови компонентов комплемента на 10-80% ниже, чем у взрослых, что сопровождается снижением биоло гической активности. После рождения наблюдается уве личение уровней некоторых сывороточных факторов комплемента, достигающих концентрации взрослых в течение месяца (например, фактора B), но повышение уровней других компонентов комплемента происходит более медленно [39]. В связи с тем, что дети имеют низкие концентрации иммуноглобулинов, эффекторная функция…”

“…146 C9 is produced primarily by the liver and is highly developmentally regulated; newborns produce substantially less than adults. 147 Like most of the other genetically determined deficiencies of complement, C9 deficiency is inherited as an autosomal recessive trait. Affected individuals usually have markedly reduced levels of C9.…”

“…Significant levels of C4, C3, C7, C9, factor B, properdin, and C1 inhibitor have been detected in fetal serum as early as the end of the first trimester or the beginning of the second trimester. 147 There is a general tendency for levels of these components to increase with age, and their levels in premature infants generally correlate with gestational age. A common problem that arises is in families with hereditary angioedema.…”
