Values of mean antiproteases were studied in 60 children with meningococcal sepsis. At illness onset, increased levels of alpha-1 antiquimotrypsin (p less than 0.001) and decreased of alpha-2 macroglobulin (p less than 0.001) were found. Moreover, patients who were complicated with a disseminated intravascular coagulation (DIC) also showed a decrease of antithrombin III (p less than 0.001) and inter alpha-1 trypsin inhibitor (p less than 0.001). There was not relationship between antiproteases levels and mortality. In 33 cases the measures were repeated 24 hours later, but no homogeneous results were found, in spite of alpha-2 macroglobulin fall in patients complicated with DIC (p less than 0.05). Phenotypic variants of alpha-1 antitrypsin were studied in 47 cases by isoelectric focusing. Results did not provide evidence that "abnormal phenotypes" (no-Pi MM) could facilitate meningococcal sepsis or DIC, but an increased number of "abnormal phenotypes" (5/9) were found in dead patients (p less than 0.025).

Previous studies suggest that there is a systemic activation of clotting and fibrinolysis in preterm infants with advanced respiratory distress syndrome (RDS). However, there are no data on the hemostatic status in the early stages of the disease; therefore, we studied some of the hemostatic parameters in these patients and made several studies at different times in preterm infants who did or did not develop RDS, using similar protocols. We found normal plasma fibrinogen, protein C, protein S, C4b-binding protein, thrombomodulin, antithrombin III, thrombin-antithrombin III complex, prothrombin fragment 1.2, plasminogen, tissue plasminogen activator, alpha-1 antitrypsin, alpha-2-macroglobulin and protein Z. However, lower D-dimer and higher plasminogen activator inhibitor and von Willebrand factor antigen levels were found within six hours of life in infants who later developed RDS compared to the control group. These findings suggest that disseminated intravascular coagulation is not prominent in the early stages of RDS. Moreover, reduced D-dimer and increased plasminogen activator inhibitor and von Willebrand factor antigen levels are probably related to the abnormalities in the fibrinolytic mechanism due to lung damage in RDS, but further studies are needed to show their pathogenic significance in RDS.
