Abstract

Community-acquired pneumonia (CAP) is now most frequent in elderly patients. CAP in the younger patient has attracted much less attention. Therefore, we compared patients with CAP aged 18 to = 65 yrs.

Data from the prospective multicentre Competence Network for Community Acquired Pneumonia Study Group (CAPNETZ) database were analysed for potential differences in baseline characteristics, comorbidities, clinical presentation, microbial investigations, aetiologies, antimicrobial treatment and outcomes.

Overall, 7,803 patients were studied. The proportion of younger patients (aged 7 mmol.L-1, respiratory rate of >= 30 breaths.min(-1), blood pressure = 60 mmHg, age >= 65 yrs)). Overall, Streptococcus pneumoniae and Mycoplasma pneumoniae were the most frequent pathogens in the younger patients. Short-term mortality was very low (1.7% versus 8.2%) and even lower in patients without comorbidity (0.3% versus 2.4%). Longterm mortality was 3.2% versus 15.9%, also lower in patients without comorbidity (0.8% versus 6.1%).

Most of the differences found clearly arise after the fifth or within the middle of the sixth decade. CAP in the younger patient is a clinically distinct entity.
