Rome and necrotizing fasciitis are associated with high morbidity and mortality (1). Although GAS virulence factors have been studied intensively, the mechanisms by which local infections progress to severe systemic infections are not yet fully understood. The systemic activation of host immune responses has been reported to account for several symptoms seen in septic patients, i.e., hypotension,

Were admitted after elective surgery were excluded that left 158 unplanned admissions in total, with only 55(34.8 ) patients surviving for more than one year. Conclusions: Although this data shows better survival for unplanned admissions than previous studies, outcomes are still poor for elderly patients who are admitted to ITU. This should inform discussions with patients and their relatives rel

Streptococcal plasminogen activator, triggers the activation of the human contact system. Activation of contact system factors at the surface of the Streptococcus pyogenes serotype M49 is dependent on streptokinase and plasminogen. Our results also show that secreted streptokinase is an efficient contact system activator, independent from a contact surface. This results in the processing of high-m

Ver the age of 65. Interestingly, there is no significant difference between the non frail and frail groups of patients admitted to intensive care. This may be because of small sample size. The length of stay of the frail patient is shorter and this may be because as intensivists we are better at treatment limitation in this group of patients. No difference in overall mortality suggests that the p

Ons trigger an activation of the contact system more potently than strains isolated from noninvasive infections. The present study gives new insights into the mechanisms by which S. pyogenes triggers the human contact system and stresses the function of soluble and surface located plasmin exploited as a group A streptococcal virulence factor through the action of streptokinase. treptococcus pyogen
