CALLY Index and Disease Activity in Ankylosing Spondylitis
The CALLY Index May Reflect Systemic Inflammatory Burden Rather Than Patient-Reported Disease Activity in Ankylosing Spondylitis: A Retrospective Cross-Sectional Study
Source: ClinicalTrials.gov · Last updated 8 Apr 2026
Brief summary (registry, in English)
This retrospective cross-sectional observational study aims to evaluate the association between the C-reactive protein-albumin-lymphocyte (CALLY) index and disease activity and functional status in patients with ankylosing spondylitis. Medical records of adult patients followed between January 1, 2022, and December 31, 2025, were reviewed. Disease activity was assessed using BASDAI and ASDAS-ESR, and functional status was evaluated using BASFI. The study investigates whether the CALLY index reflects systemic inflammatory burden beyond patient-reported disease activity
