Evaluation of hematological parameters related to systemic inflammation in acute and subacute/chronic low back pain.

Abstract

Aim: To compare the hematological parameters associated with systemic inflammation between acute and subacute/chronic nonspecific low back pain and to evaluate their diagnostic roles in relation to chronicity in low back pain. Materials & methods: This retrospective case-control study included 150 participants aged 18-65 years with acute nonspecific low back pain, 150 with subacute/chronic nonspecific low back pain, 150 as the control group. Results: Red cell distribution width was significantly higher in the subacute/chronic pain group compared with the acute pain group (p=0.003), and had a poor diagnostic value for chronicity (cutoff: 11.95, p=0.003). There were no significant differences in terms of other parameters (p>0.05). Conclusion: Red cell distribution width has a poor diagnostic value for chronicity in nonspecific low back pain.
