| Summary: | Abstract Background Fibrinogen albumin ratio (FAR) is recently considered as a new marker for inflammation. This study aimed to evaluate the value of FAR as a predictor biomarker of ankylosing spondylitis (AS) disease activity as well as its correlation with the spondyloarthritis research consortium of Canada MRI index (SPARCC) of sacroiliac joints (SIJs) in detection of disease activity in AS. The study included 25 adult AS patients and 10 healthy controls who were matched for age and sex. Based on disease activity, patients were divided into two groups: Group (I) consisted of 15 patients with active disease with a BASDAI ≥ 4, and group (II) consisted of 10 patients with inactive disease with a BASDAI < 4. Results The mean of patients age was (35.2 years); patient’s disease duration range (1.5–18 years). AS patients with disease activity had a higher FAR and SPARCC MRI index in comparison with the remission and control groups (P < 0.01). FAR and the SPARCC MRI index were found to be positively correlated in patients with active illness (P < 0.01). Cut-off value of FAR > 0.086, SPARCC index > 4. FAR and SPARCC MRI index can significantly differentiate between active and inactive group (P < 0.001) with 100% sensitivity and specificity. FAR can significantly differentiate between AS patients and health controls (P < 0.001), with 80% sensitivity and 100% specificity. SPARCC index also can significantly differentiate between AS patients and health controls (P < 0.001) but with 88% sensitivity and 100% specificity. Conclusions The study concluded that FAR and SPARCC MRI index were elevated in patients with active AS disease. FAR and SPARCC MRI index can serve as a new parameter in monitoring activity in ankylosing spondylitis disease. |
