Clinical features of clostridial. Rapid institution of treatment for C. perfringens infection has indeed been reported to be life saving in a minority of patients. Penicillin combined with clindamycin showed better outcome compared with single drug. Hemostatic tests revealed increased prothrombin time (PT) >100 seconds, increased partial thromboplastin time (APTT) 81.9 seconds and decreased fibrinogen (249 mg/L). In one study, diabetes was present in 30% of patients with C. perfringens bacteremia, being the only risk factor in 15%, as in our case.2, Sudden severe hemolytic anemia was believed to be caused by toxin production of C. perfringens. These patients have jaundice and red-tinged serum and urine. Firstly, the diagnosis of C. perfringens sepsis is difficult without its identification in blood cultures, most likely due to the anaerobic conditions required for growth. What is more frightening is that in the large majority of cases the time from admission to death was within hours, as it was in our case. This is called the CAMP test.
