Procedures: In an observational cohort of subjects with community-acquired pneumonia recruited from emergency departments in 28 hospitals, we divided subjects into 5 age groups. We measured circulating levels of inflammatory, hemostasis, and cell-surface markers for the duration of the first week of hospitalization and at discharge and compared 90-day mortality. We employed logistic regression to examine odds ratios for 90-day mortality amongst age groups, adjusting for differences in pre-infection factors alone and after that in addition adjusting for immune markers. Outcomes: Of 2,183 subjects, 495, 444, 403, 583, and 258 subjects were,50, 5164, 6574, 7584, and $85 years of age, respectively. Significant age-related differences had been observed in 90-day mortality. No age-related variations in inflammatory and cell surface markers occurred through the first week. Older subjects had higher pro-coagulant markers on ED presentation and over first week, but these variations have been modest. Odds of death for older adults changed minimally in models incorporating variations in hemostasis and inflammatory markers. At discharge, regardless of clinical recovery as evidenced by normal vital indicators in.85% subjects, older subjects had modestly increased hemostasis markers and IL-6 levels. Conclusions: Modest age-related increases in coagulation response occur in the course of hospitalization for CAP; on the other hand these differences don't explain the significant differences in mortality. In spite of clinical recovery, immune resolution can be delayed in older adults at discharge. Citation: Kale S, Yende S, Kong L, Perkins A, Kellum JA, et al.
