Eculizumab Half life of approximately 11 days following IV

administration. Distributed in the vascular space The inhibition of complement activation at the

level of C5 creates a functional C5 deificiency Blockade of the complement cascade at the C5

level does preserve the early components of complement that are essential for the opsonization of microorganisms and the clearance of immune complexes

Increased risk for Neisseria meningitides

Dramatic response First goes the platelets

146,000 at 31/5 * 160,000 at 1/6 * 309,00 at 4/6

Next come the kidneys

2.42 mg/dl at 4/6 * 2.17 mg/dl at 7/6 * 1.67 mg/dl at 9/6 * 1.56 mg/dl at 12/6

The hemoglobin takes its time getting to 10 mg% only after 3 weeks

LDH is last

1600 at 7/6 * 1112 at 17/6

5/6/12 discharged home

And since then… C3, C4 – normalized and stays within normal range

since 10/6/12 Hb around 12.0, Plt and LDH within normal range,

haptogobin high-normal Creatinine level declined gradually for the next few

weeks, currently around 1.05 mg/dl. No proteinuria BP improving, however still receiving calcium

channels blockers, beta blockers, ACE inhibitors

Slow tapering of steroids, no UC flares up

Monitoring complement blockade CH50 assays A useful tool for detecting a deficiency of the

classical pathway by assessing the ability of serum to lyse sheep erythrocytes

All nine components of the classical pathway (C1-C9) are required in order to reach a normal CH50 level

A blockade of C5-9 complex by eculizumab would result in low levels of CH50
