FSAP-inhibitor complexes in plasma of children with meningococcal sepsis. FSAP-AP (A) and FSAP-C1-inh (B) complexes were measured in citrated plasma from 38 meningococcal sepsis patients. Blood was sampled at 0 h, 12 h, 24 h and 3 months. FSAP-inhibitor complexes were expressed as AU/ml. Plasma of 20 healthy donors was taken as a control. Median values at a given time have been compared by using Mann Whitney Rank Sum test. *** indicates a P < 0.001, ** indicates a P < 0.01.
