Summary

Chronic spondylarthropathy (SpA) patients showed significant functional decline over three years, as measured by key indices. This highlights challenges in long-term SpA intervention studies.

Area of Science:

  • Rheumatology
  • Clinical Medicine
  • Patient Outcomes

Background:

  • Chronic spondylarthropathy (SpA) management requires understanding long-term functional trajectories.
  • Accurate assessment of functional capacity is crucial for planning interventions and follow-up strategies.

Purpose of the Study:

  • To evaluate the long-term functional outcomes in patients with chronic spondylarthropathy (SpA) using validated functional indices.
  • To inform the design of future long-term intervention studies and optimize follow-up methodologies for SpA.

Main Methods:

  • A cohort of 65 SpA patients (mean age 49, mean diagnosis duration 12 years) completed functional questionnaires at baseline and 3-year follow-up.
  • Utilized indices included Bath Ankylosing Spondylitis Functional Index (BASFI), Dougados Functional Index (DFI), Health Assessment Questionnaire for Spondylarthropathies (HAQ-S), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Patient Global Assessment (BAS-G), and Stiffness-VAS.

  • Patients reported life events and health factors that could influence outcomes during the follow-up period.

    • Main Results:

    • Most functional indices (BASFI, DFI, BASDAI, BAS-G, Stiffness-VAS) demonstrated a statistically significant reduction in patient functional capacity or health status over three years.
    • The Health Assessment Questionnaire for Spondylarthropathies (HAQ-S) did not show a significant change.
    • Numerous confounding factors, including life events and health-related issues, likely influenced the observed index results over the study period.

    Conclusions:

    • The natural course of chronic spondylarthropathy (SpA) appears to involve functional impairment when assessed by common indices over the long term.
    • Separating the effects of specific interventions, such as rehabilitation, in long-term SpA follow-up studies is challenging due to numerous interfering life and health events.
