Spondyloarthritis

Last edited: 4/16/2026

Overview

Spondyloarthritis (SpA) encompasses a heterogeneous group of chronic inflammatory diseases affecting the spine, peripheral joints, and entheses, often characterized by inflammation and potential extra-articular manifestations such as uveitis and skin conditions 1231033.

Diagnosis

  • Key Criteria: Inflammatory back pain, sacroiliitis on imaging, and enthesitis 2533.
  • Recommended Tests: HLA-B27 testing, MRI of sacroiliac joints, and ultrasound for enthesitis 51844.
  • Grading: ASAS (Assessment of SpondyloArthritis International Society) criteria for axial SpA, including imaging and clinical features 444.
  • Early Detection: Specific tools like DUET (Dublin Uveitis Evaluation Tool) for uveitis patients 46.
  • Management

  • First-Line Treatments: Nonsteroidal anti-inflammatory drugs (NSAIDs) for symptom control 2537.
  • Second-Line Treatments: Tumor necrosis factor (TNF) inhibitors for moderate to severe disease 334551.
  • Adjunctive Therapies: Physical therapy, exercise, and lifestyle modifications including diet 1651.
  • Glucocorticoids: Used for acute flares or specific indications, but limited due to side effects 28.
  • Special Populations

  • Pregnancy: Tailored management with caution on TNF inhibitors; consider alternative therapies like IL-23/IL-17 inhibitors 11.
  • Pediatrics: Juvenile Spondyloarthritis Disease Activity Index (JSpADA) for monitoring 52.
  • Comorbidities: Increased risk of comorbidities like cardiovascular disease and metabolic syndrome; regular screening recommended 40.
  • Key Recommendations

  • Early Diagnosis and Referral: Implement strategies for early detection and referral of patients with inflammatory back pain 4655.
  • (Evidence: Moderate)
  • Use of Imaging: Incorporate MRI and ultrasound for accurate diagnosis and monitoring of SpA 1844.
  • (Evidence: Strong)
  • TNF Inhibitors for Severe Disease: Initiate TNF inhibitors for patients with moderate to severe axial SpA who fail NSAIDs 3345.
  • (Evidence: Strong)
  • Regular Monitoring of Comorbidities: Screen for and manage comorbidities such as cardiovascular disease and sarcopenia in SpA patients 940.
  • (Evidence: Moderate)
  • Personalized Treatment Plans: Tailor treatment plans considering patient-specific factors including gender and comorbidities 1033.
  • (Evidence: Moderate)
