| description | <p>Inflammatory processes are known to be involved at least in the early phase of complex regional pain syndrome type 1 (CRPS1). Blister fluid obtained from the involved extremities displayed increased amounts of proinflammatory cytokines IL-6 and TNF<mml:math alttext="$alpha $"> <mml:mi>α</mml:mi> </mml:math> compared with the noninvolved extremities. The aim of this paper is to investigate the involvement of mediators by measurement of several other cytokines using new detection techniques that enable multiple cytokine measurement in small samples. The use of a multiplex-25 bead array cytokine assay and Luminex technology enabled simultaneous measurement of representative (1) proinflammatory cytokines such as GM-CSF, IL-1<mml:math alttext="$eta $"> <mml:mi>β</mml:mi> </mml:math>, IL-1RA, IL-6, IL-8, and TNF-<mml:math alttext="$alpha $"> <mml:mi>α</mml:mi> </mml:math>; (2) Th1/Th2 distinguishing cytokines IFN-<mml:math alttext="$gamma $"> <mml:mi>γ</mml:mi> </mml:math>, IL-2, IL-2R, IL-4, IL-5, and IL-10; (3) nonspecific acting cytokines IFN-<mml:math alttext="$alpha $"> <mml:mi>α</mml:mi> </mml:math>, IL-7, IL-12p40/p70, IL-13, IL-15, and IL-17; and (4) chemokines eotaxin, IP-10, MCP-1, MIP-1<mml:math alttext="$alpha $"> <mml:mi>α</mml:mi> </mml:math>, MIP-1<mml:math alttext="$eta $"> <mml:mi>β</mml:mi> </mml:math>, MIG, and RANTES.
