In contrast, any individual with increased complement levels or activity would have an elevated CH50 since increasing dilution would be necessary to reach the 50% lyse marking. Decreased CH50 values may be seen in cirrhosis or hepatitis [ 6 ] as a result of impaired complement production in the liver.
The cause of complement deficiency is genetics (though cases of an acquired nature do exist post infection). The majority of complement deficiencies are inherited as autosomal recessive conditions, while properdin deficiency occurs through X-linked inheritance. MBL deficiency can be inherited by either manner. [2]

Terminal complement pathway deficiency is a genetic condition affecting the complement membrane attack complex (MAC).. It involves deficiencies of C5, C6, C7, and C8. (While C9 is part of the MAC, and deficiencies have been identified, [1] it is not required for cell lysis.
The cleaved products attract phagocytes to the site of infection and tags target cells for elimination by phagocytosis. In addition, the C5 convertase initiates the terminal phase of the complement system, leading to the assembly of the membrane attack complex . The membrane attack complex creates a pore on the target cell's membrane, inducing ...
C-reactive protein (CRP) is an annular (ring-shaped) pentameric protein found in blood plasma, whose circulating concentrations rise in response to inflammation.It is an acute-phase protein of hepatic origin that increases following interleukin-6 secretion by macrophages and T cells.

Danicopan, sold under the brand name Voydeya, is a medication used for the treatment of paroxysmal nocturnal hemoglobinuria. It is a complement inhibitor which reversibly binds to factor D to prevent alternative pathway-mediated hemolysis and deposition of complement C3 proteins on red blood cells. The most common side effects include fever, headache, increased levels of liver enzymes (a sign ...
