Sepsis score and acute-phase protein response as predictors of outcome in septic surgical patients.

In a series of 135 patients with severe surgical infections, we determined the sepsis score and the plasma level of the acute-phase proteins alpha-1-acid glycoprotein, alpha 1-antitrypsin, complement factor B, and C3. The initial sepsis score was a strong determinant of survival: in survivors it was significantly lower than in nonsurvivors. Only 8% of patients with a sepsis score above 20 survived. At the onset of severe sepsis, the plasma levels of all four acute-phase proteins were significantly lower in nonsurvivors. A significant elevation of C3a levels in the plasma of both surviving and nonsurviving patients indicated marked consumption of complement components in all patients with severe sepsis. A linear equation was developed to predict survival: sepsis index of survival (SIS) % = 121 + 0.26 (complement factor B) + 0.36 (alpha-1-acid glycoprotein)-6 (sepsis score). Based on our analysis, at the onset of severe sepsis, an SIS of 50% or more can correctly predict 88% of survivors and an SIS less than 50% can correctly predict 86% of nonsurvivors several days in advance of clinical outcome.

Diagnosing malnutrition.

The measurement of selected anthropometric, biochemical and immunological variables, and clinical judgment can be used to assess nutritional state. Nutritional assessment has three main aims: to define the type and severity of malnutrition; to identify high risk patients; to monitor the efficacy of nutritional support. The problems associated with the various methods to assess the nutritional state and the applications of nutritional assessment in clinical practice are presented and discussed.

Sepsis score and complement factor B for monitoring severely septic surgical patients and for predicting their survival.

Sepsis score and complement factor B (FB) have been measured in 66 severely septic surgical patients in the intensive care unit, with the aim of monitoring their clinical course and predicting their outcome. Sepsis score correlated well with clinical course. 82% of patients with initial sepsis score less than 20 progressively improved and survived. Only 6% of patients with sepsis score greater than or equal to 20 survived. FB plasma level was significantly higher (p less than 0.01) in patients who subsequently survived. Two indices were identified which could predict patient outcome several days in advance with 100% accuracy: (1) the index of survival from sepsis defined as the combination of sepsis score less than 20 and FB greater than or equal to 45 mg/dl, and (2) the index of death from sepsis defined as sepsis score greater than or equal to 20 and FB less than 40 mg/dl.

Pulsed Doppler diagnosis of tricuspid insufficiency.

To verify the ability of Pulsed Doppler Echocardiography (PDE) to detect flow abnormalities in tricuspid insufficiency (TI), 27 normal controls and 83 heart patients (pts) were studied. The latter group underwent an invasive diagnostic evaluation. The PDE examination did not reveal any significant systolic flow alteration in the normal controls. However, in the heart patients, a systolic turbulence was recorded within the right atrium both on audio and on graphic system (Time Interval Histogram-TIH) in 28 cases. Angiography showed tricuspid regurgitation in 24 pts. The sensitivity of PDE was 92%, the specificity was 93% and the predictive value was 96%. There were two false negative and four false positive cases. In conclusion, Pulsed Doppler Echocardiography is a highly reliable technique for the qualitative diagnosis of tricuspid insufficiency in patients with acquired heart disease. Left-to-Right shunts, namely left-to-right atrium and left ventricle-to-right atrium, can create flow disturbances that mimic tricuspid insufficiency. No criteria were identified, which correlated well with the angiographic severity of the tricuspid regurgitation.
