dc.description.abstractObjective: This study aims to compare serum pregnancy-associated plasma protein A (PAPP-A) levels in surviving and nonsurviving elderly patients with community-acquired pneumonia (CAP), investigating whether PAPP-A is correlated with CAP prediction scores and whether PAPP-A can successfully predict 28-day mortality rates in elderly patients. Methods: This prospective, observational, single-center, cross-sectional study was conducted at the emergency department (ED) of Celal Bayar University Hospital in Manisa, Turkey, between January and September 2014. All patients underwent follow-up evaluations 28 days after admission. The end point was defined as all-cause mortality. Results: A total of 100 elderly patients (mean age, 77.3 +/- 7.6 years [range, 65-94 years]); 60% men) with CAP were enrolled in this study. All-cause mortality at the 28-day follow-up evaluation was 22%. Admission PAPP-A levels were significantly higher in nonsurvivors compared with 28-day survivors (10.3 +/- 4.5 vs 3.8 +/- 2.6 ng/mL, P < .001). A significant and positive correlation between admission PAPP-A levels and pneumonia severity index; confusion, oxygen saturation, respiratory rate, blood pressure, and age 75 years or older; and confusion, urea, respiratory rate, blood pressure, and age older than 65 years scores was found (r = .440, P < .001; r = .395, P < .001; and r = .359, P < .001, respectively). Moreover, we determined that the optimal PAPP-A cutoff for predicting 28-day mortality at the time of ED admission was 5.1 ng/mL, with 77.3% sensitivity and 77.9% specificity. Conclusions: Serum PAPP-A level is valuable for predicting mortality and the severity of the disease among elderly patients with CAP at ED admission. Thus, PAPP-A might play a further role in the clinical assessment of the severity of CAP. (C) 2015 Elsevier Inc. All rights reserved.
