The sera of 87 Senegalese patients with various forms of leprosy were investigated. Two of the most reliable methods were used to detect circulating immune complexes : the radiolabelled C1q binding test and the Raji cell binding technique. Several fractions of complement, including C3, C4, factor B and the C3d product of C3 were also assayed. A material having the properties of immune complexes was detected in lepromatous and reactional leprosy. In tuberculous leprosy, only the Raji cell binding technique gave positive results. C3 and C4 were normal or slightly raised, but C3d was increased in all forms of the disease. There was no significant correlation between C3d values and the results of immune complexes detection tests.

UI MeSH Term Description Entries
D007918 Leprosy A chronic granulomatous infection caused by MYCOBACTERIUM LEPRAE. The granulomatous lesions are manifested in the skin, the mucous membranes, and the peripheral nerves. Two polar or principal types are lepromatous and tuberculoid. Hansen's Disease,Hansen Disease
D003176 Complement C3 A glycoprotein that is central in both the classical and the alternative pathway of COMPLEMENT ACTIVATION. C3 can be cleaved into COMPLEMENT C3A and COMPLEMENT C3B, spontaneously at low level or by C3 CONVERTASE at high level. The smaller fragment C3a is an ANAPHYLATOXIN and mediator of local inflammatory process. The larger fragment C3b binds with C3 convertase to form C5 convertase.
