This study compares biomarker (including procalcitonin, pro-ANP, and copeptin) levels to pneumonia severity scores to predict 30-day mortality in NHAP (nursing home acquired pneumonia) patients. ⋯ Among 3 biomakers, copeptin was the strongest predictor of 30-day mortality from NHAP. The pathophysiologic and clinical implications of this finding require further investigation.

Bacteremia is a severe bacterial infection with significant mortality. Clinical parameters that reliably predict it are less elucidated. We assessed the potential of serum adhesion molecules for predicting bacteremia and compare it with current available infection biomarkers to determine a more timely predictor of adult severe sepsis patients on admission to the emergency department (ED). ⋯ Although serum cell adhesion markers are not specific for predicting bacteremia in septic patients, higher mean serum cell adhesion molecules levels on admission may imply both more severe infection and presence of bacteremia. Assay of serum adhesion molecules may be added as an infectious marker among the panel of bacteremic parameters in clinical practice, especially since early diagnosis and prompt antimicrobial therapy are essentially for survival.
