Sepsis and antithrombin III, prekallikrein, and fibronectin levels in surgical patients.
Antithrombin (AT), prekallikrein (PK), and fibronectin (FN) were measured in the plasma of 400 patients with a variety of disease states seen at Detroit Receiving Hospital from October 1983 through June 1987. The average lowest AT measured in these 400 patients was 69 +/- 19 per cent (SD) (Normal = 75-120%). The average lowest AT level in 152 septic patients (50 +/- 17%) was significantly lower than in the 248 patients without sepsis (79 +/- 22%) (P less than 0.001). The average lowest PK levels measured in 132 patients was 52 +/- 19 (Normal = 80-120%). The average PK level in 64 septic patients (34 +/- 17%) was significantly lower than in 68 who were not septic (69 +/- 21%) (P less than 0.001). The average lowest FN levels measured in 109 patients was 230 +/- 118 mcg/ml (Normal = 200-350 mcg/ml). The average FN level in 47 septic patients (162 +/- 88 mcg/ml) was significantly lower than in the 62 nonseptic patients (285 +/- 138) mcg/ml. AT or PK levels less than 50 per cent or FN levels less than 150 mcg/ml during the first 24 to 48 hours after severe trauma or burns were associated with a development of later sepsis in 90 per cent, 77 per cent, and 70 per cent, respectively. Thus, low or falling levels of AT, PK, and FN may be of great help in predicting sepsis or providing an early diagnosis in critically ill or injured patients.
