Comparative Study Clinical Trial Controlled Clinical TrialFibronectin and other DIC-related variables in septic ICU patients receiving cryoprecipitate.
In a controlled study of fibronectin supplementation in sepsis, 11 ICU patients in septic shock were scheduled to receive either cryoprecipitate from 20-40 donors (n = 6) or 250-300 ml of stored plasma (n = 5) (two infusions over 24 h). We wanted to: compare some "conventional" DIC variables in the ICU (platelet count, prothrombin complex = NT, FDP) to additional variables: Fibronectin (Fn), fibrinogen (Fg), F V, FVIII R:Ag, F VIII:C activity, F XII, plasminogen (Plg), antiplasmin (AP), antithrombin (AT), kallikrein inhibiting activity (KI) and spontaneous proteolytic activity (SPA): study the effects of cryoprecipitate or plasma infusion on three variables. Samples were taken before the first infusion, and 24 and 48 h after. ⋯ Five patients were thrombocytopenic, and in these a pattern with low levels of Plg and AT was observed. Fn did not correlate well to the other variables measured. These results indicate a marked activation of coagulation and fibrinolysis in these severely ill patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Plasmapheresis in the treatment of severe meningococcal or pneumococcal septicaemia with DIC and fibrinolysis. Preliminary data on eight patients.
Plasmapheresis (50 ml fresh frozen plasma/kg body weight per session--total 9-11 liters) was performed within 36 hours of the onset of septicaemia in 7 patients (1 woman and 6 men, age 14-48 years). One 8 year old girl was treated with exchange blood transfusion (2 liters). All had symptoms of severe septic shock caused by Neisseria meningitidis (6) or by Streptococcus pneumoniae (2). ⋯ Persistent extreme values were observed in 2 patients that died, whereas coagulation/fibrinolysis parameters frequently improved during plasmapheresis and gradually (more than 6 days) returned to normal values in the survivors. Although plasmapheresis was largely successful and signs of DIC and fibrinolysis were normalized, 2 patients died and 1 survived with severe sequelae. Thus, it remains to accumulate more data to conclude if plasmapheresis is beneficial in the treatment of severe septic shock and DIC.
