摘要: Inherited deficiencies of complement components are associated with an increased risk infection by encapsulated, high grade bacterial pathogens such as Streptococcus pneumoniae, Haemophilus influenzae type b and Neisseria meningitidis. Hence, the levels antibodies to capsular polysaccharide antigens were measured using ELISA in 65 patients inherited covering classical, alternative terminal cascade. Three four C3-deficient individuals studied found be almost totally deficient specific anti-pneumococcal (PCP) antibodies. These had a history recurrent pneumococcal sepsis. While single C1r, C2 C1Inh deficiency have low anti-PCP antibody levels, no other group significantly reduced compared 100 controls. Antibody two polysaccharides not lower patient groups. findings suggest that C3 may able provide stimulatory signal promote production
