Sepsis-associated purpura fulminans in adults.
Sepsis-associated purpura fulminans is defined as septicemia, shock, disseminated intravascular coagulation and circulatory failure leading to multiple organ dysfunction. 40-70% of patients with sepsis-associated purpura fulminans die. Early prognostic factors in adults have not been well delineated yet. Aim of our study was 1) to evaluate currently used scoring systems for meningococcal septicemia in the setting of sepsis-associated purpura fulminans and 2) to assess if other parameters are feasible as early prognostic factors. From 1.1 1994-31.12.1998 twelve patients (female: 7; mean age: 31 (21; 43) years) were studied. Six patients (50%) died within 2 hours and 7 days after admission despite standard intensive treatment. On admission non-survivors had a more pronounced degree of disseminated intravascular coagulation compared to survivors (platelet count 18000 (15000; 45000) G/l vs. 119.000 (111000; 152000) G/l, (p = 0.03); fibrinogen 67 (50; 108) mg/dl vs. 356 (234; 483) mg/dl, (p = 0.02); PTZ 28% (20%; 30%) vs. 44% (35%; 51%), (p = 0.05); aPTT 120 (120; 128) sec vs. 46 (44; 69) sec, (p = 0.001). Severity of lactic acidosis was significantly higher in non-survivors than in survivors (pH 7.08 (6.92; 7.21) vs. pH 7.4 (7.25; 7.4), (p = 0.02); lactate 13.5 (11; 15) mval/l vs. 6.0 (4.4; 6) mval/l, (p = 0.02); data presented as median (25-75% interquartile range). In our patients the Glasgow Meningococcal Septicemia Prognostic Score (GMSPS) and the Niklasson-Score failed to distinguish between survivors and non-survivors (GMSPS 7 (6; 11) vs 7.5 (7; 9) out of 15; predicted mortality according to Niklasson-Score 73% vs 88%). There was no difference in the APACHE II Score (22 (18.5, 24) vs 22 (20.25, 26)). The severity of disseminated intravascular coagulation assessed by routine laboratory parameters and the degree of lactic acidosis on admission were the strongest predictors of outcome in patients with sepsis-associated purpura fulminans. Scoring systems developed for patients with meningococcal septicemia are of limited value in the setting of sepsis-associated purpura fulminans.
