“…Alternatively, the functional complement activity can be determined as CH50 or CH100. A genetically fixed deficiency of various complement factors including C2 and/or C4, as well as complement protein polymorphisms, are associated with subsets of SLE [65][66][67][68][69].…”

“…Immunogenetic factors may be found within the complex of human leukocyte antigens (HLA), mainly for SCLE [36,42,63,64]. Furthermore, genetic deficiencies of various complement factors [65][66][67][68][69], as well as functional polymorphisms of tumor necrosis factor-α [63,64,70], may result in a delayed disposal of apoptotic material. Environmental factors include smoking [71] and various infectious agents of mainly viral origin (cytomegalovirus [CMV] and Epstein-Barr virus [EBV]), as well as UV light [62].…”

“…190 kDa e sua ausência impede a formação do MAC e a produção de C5a (Morgan &Walport, 1991). Assim, a deficiência de C5 está associada com o aumento da susceptibilidade a infecções respiratórias, infecções graves por microorganismos do gênero Neisseria, otite, febre, além de sintomas mais inespecíficos como alopecia, hipopigmentação do couro cabeludo, crostas e eritema (ASGHAR et al, 1991;NIELSEN & KOCH 1987). Sabe-se ainda que os soros de alguns indivíduos C5D não exibem atividade quimiotáxica para neutrófilos, provavelmente em virtude da produção diminuída de fragmentos C5a (ROSENFELD et al, 1976;SNYERMAN et al, 1979).…”
