Abstract

Background:

Acute septic arthritis (ASA) is the most common pediatric orthopaedic infection, and may be associated with severe sequelae. An improved understanding of the intra-articular inflammatory response in ASA may facilitate the use of immunomodulatory agents to attenuate the deleterious effects of the host immunological response on synovial tissue, help monitor disease progression and differentiate ASA from non-infectious arthritides. To our knowledge, no study has characterized the intra-articular cytokine response in children with ASA in detail. Given this, we attempted to validate a multi-plex cytokine assay for use in the blood and synovial fluid of children with ASA.

Methods:

Twelve children (8 controls undergoing orthopaedic surgery for non-infectious conditions and 4 with ASA) were prospectively enrolled over 14-months. Blood and synovial fluid were simultaneously collected intra-operatively from each subject, and the levels of 40 different cytokines were determined using a 40-plex assay (BioRad). Cytokines were grouped by function and structure into 12 different groups for analysis. Given the large number of comparisons undertaken, the Benjamini-Hochberg method was utilized to control for type 1 errors, with an a priori false discovery rate of 10% utilized.
