title: Serum kinetics of soluble triggering receptor expressed on myeloid cells-1 differs in relation to the type of arthroplasty.
abstract: BACKGROUND
  Soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) participates in the inflammatory process.
  
  
  OBJECTIVE
  To describe changes of sTREM-1 in the serum after hemiarthroplasty (HA) and total hip arthroplasty (THA).
  
  
  METHODS
  Serial blood samples were drawn from 122 patients with hip fracture. Interleukin-6 (IL-6), sTREM-1, and C-reactive protein (CRP) were measured.
  
  
  RESULTS
  IL-6 and CRP were similarly increased after both HA and THA. sTREM-1 was increased early in HA and late after THA. The only parameter that was higher among patients who developed systemic inflammatory response syndrome was IL-6.
  
  
  CONCLUSIONS
  Kinetics of sTREM-1 differs among patients undergoing HA of the hip and those undergoing THA.
