Clinical Trial Summary

The aim of the study is to compare the neutrophils to lymphocytes ratio (NLR), platelets to lymphocytes ratio (PLR), eosinophils to lymphocytes ratio (ELR), red blood cell distribution width (RDW), mean platelet volume (MPV), systemic immune inflammation index (SII), erythrocyte sedimentation rate (ESR) and C reactive protein (CRP) which are the hematological parameters associated with systemic inflammation in acute and subacute/chronic low back pain. Secondary purpose; evaluation of the prognostic roles of hematological parameters associated with systemic inflammation in low back pain in predicting chronicity.This study is a retrospective case-control study. The data of patients who applied to the emergency department with the complaint of acute (less than 4 weeks) low back pain or to the Physical Medicine and Rehabilitation outpatient clinic with the complaint of subacute (lasting 4-12 weeks) or chronic (longer than 12 weeks) non-specific low back pain in the last 3 years will be scanned. The data of patients who applied with complaints other than medical conditions known to be associated with painful conditions and/or inflammatory response will be screened as a control group. The data of patients between the ages of 18-65 will be included in the study. In conclusion, the data of 150 patients who presented with acute non-specific low back pain, 150 patients who presented with subacute/chronic non-specific low back pain and 150 participants as the control group will be included in the study for use in analysis. Participants' age, gender, duration of low back pain (days), if evaluated, conditions associated with low back pain in cases with subacute/chronic pain, ESR, CRP, RDW, MPV, neutrophil count, lymphocyte count, eosinophil count and platelet count in blood tests at admission examinations will be recorded. NLR will be calculated by dividing the number of neutrophils by the number of lymphocytes, PLR by dividing the number of platelets by the number of lymphocytes, ELR by dividing the number of eosinophils by the number of lymphocytes, and SII by the formula "platelet numberxneutrophil number/lymphocyte number".
