Assessment of spinal pain

Area of Science:

• Rheumatology
• Medical Imaging
• Genetics

Background:

• Spinal pain is common, with most cases being non-specific low back pain.
• Chronic inflammatory back pain (IBP) is a hallmark of axial spondyloarthritis (axSpA), but its early recognition in primary care is challenging.
• Accurate diagnosis of axSpA is essential for timely intervention and management.

Purpose of the Study:

• To highlight the importance of identifying inflammatory back pain (IBP) for early diagnosis of axial spondyloarthritis (axSpA).
• To discuss the role of clinical, genetic (HLA-B27), and imaging parameters in improving axSpA diagnosis and referral.
• To emphasize the critical function of imaging in differentiating axSpA from other spinal conditions.

Main Methods:

• Review of diagnostic criteria and challenges in primary care for axSpA.
• Analysis of the utility of clinical parameters, human leukocyte antigen (HLA) B27 testing, and imaging.
• Focus on conventional radiography and magnetic resonance imaging (MRI) for visualizing spinal and sacroiliac joint changes.

Main Results:

• Inflammatory back pain (IBP) is a key indicator for axSpA, distinct from non-specific back pain.
• Imaging, particularly MRI and conventional radiographs, is vital for detecting structural changes (e.g., syndesmophytes) and inflammation (e.g., sacroiliitis, spondylitis).
• Genetic factors, notably HLA B27, ERAP-1, and IL-23R, play a significant role in axSpA pathogenesis.

Conclusions:

• Early identification of IBP and axSpA is critical and requires improved diagnostic strategies in primary care.
• Integrating clinical assessment, HLA-B27 status, and advanced imaging can enhance the diagnostic pathway for axSpA.
• Understanding the genetic underpinnings of axSpA provides further insight into disease mechanisms and potential therapeutic targets.
