Objectives

Narrative objectives1

Evaluation of transition of Toll-like receptor (TLR)2 and CD64 expression on peripheral blood mononuclear cell (PBMC) in pneumonia patients. Comparison between expression of these receptors on PBMC with several cytokines and procalcitonin (PCT).
Ordinal inflammatory markers such as white blood cell counts, c-reactive protein and IK-6 are not perfect markers for evaluating severity of infectious diseases, because these are easily influenced by underlying diseases, administration of immunosuppressive agents and patient clinical history. Newer and reliable markers are urged to be developed in clinical practice. The main objective of this study is that quantification of TLR2 and CD64 expression on PBMC may contribute to evaluation of severity and prognosis of pneumonia patients with high sensitivity.

Assessment

Primary outcomes

(1) Evaluation of relation between severity of pneumonia and expression of TLR2 and CD64 on PBMC of pneumonia patient. Severity of pneumonia is defined by A-DROP, PSI, I-ROAD, and their combinations.
(2) Evaluation of relation between common inflammatory markers and expression of TLR2 and CD64 on PBMC of pneumonia patient. Common inflammatory markers are C-reactive proteins, white blood cell count, cytokines and procalcitonin.
(3) Evaluation of relation between patient outcome and prognosis and expression of TLR2 and CD64 on PBMC of pneumonia patient.
(4) Evaluation of relation between causative agents and expression of TLR2 and CD64 on PBMC of pneumonia patient.
