Management of Inflammatory Arthritis

Diagnostic Workup

The American College of Rheumatology suggests that elevated inflammatory markers, such as ESR and CRP, with joint symptoms mandate immediate rheumatology referral, with a strength of evidence rated as high 2
The presence of rheumatoid factor (RF) and anti-CCP antibodies, especially high-titer, indicates rheumatoid arthritis and requires urgent referral, according to the American College of Rheumatology, with a strength of evidence rated as high 1, 2
The American College of Rheumatology recommends screening for systemic autoimmune conditions with ANA (antinuclear antibody) 1
Creatine kinase (CK) is essential to rule out myositis, which can present with shoulder pain and requires different management, as stated by the American College of Rheumatology 1

Morning stiffness duration of ≥30 minutes indicates inflammatory arthritis and mandates immediate rheumatology referral, according to the American College of Rheumatology, with a strength of evidence rated as high 2
Pain that improves with movement (rather than worsening) suggests inflammatory rather than mechanical pathology, as stated by the American College of Rheumatology 2
The American College of Rheumatology recommends examining for joint swelling, as any synovitis requires rheumatology referral within 6 weeks, immediately if present beyond 4 weeks 2

The American College of Rheumatology suggests referring immediately if morning stiffness ≥30 minutes, elevated CRP or ESR with joint symptoms, positive RF or anti-CCP antibodies, or requiring >20 mg prednisone daily that cannot be tapered below 10 mg/day within 4 weeks, with a strength of evidence rated as high 2
Any evidence of muscle weakness (suggests myositis, which is life-threatening) requires immediate referral, as stated by the American College of Rheumatology 2

For moderate symptoms (Grade 2: limiting instrumental activities of daily living), the American College of Rheumatology recommends increasing prednisone to 20 mg daily, with a strength of evidence rated as moderate 1
For severe symptoms (Grade 3: limiting self-care activities), the American College of Rheumatology suggests increasing prednisone to 40 mg daily or 1 mg/kg/day, with a strength of evidence rated as moderate 1
The American College of Rheumatology recommends adding proton pump inhibitor for GI prophylaxis when escalating corticosteroid therapy, with a strength of evidence rated as high 3

The American College of Rheumatology suggests using NSAIDs (if no contraindications) for symptomatic management while awaiting rheumatology, as they are more effective than muscle relaxants for joint pain, with a strength of evidence rated as high 1, 3
The American College of Rheumatology recommends acetaminophen for additional analgesia, with a strength of evidence rated as moderate 1
Patient education about "sick day rules" and when to seek urgent care is essential, as stated by the American Society of Clinical Oncology, with a strength of evidence rated as high 5

The American College of Rheumatology suggests considering polymyalgia rheumatica if patient is >50 years old, presents with bilateral shoulder/hip girdle pain and elevated inflammatory markers, with a strength of evidence rated as moderate 1
The American College of Rheumatology recommends checking medication list and CK level to rule out statin-induced myopathy, with a strength of evidence rated as high 4
