Management of Migratory Non-Erosive Asymmetrical Polyarthritis with Hepatitis

For migratory non-erosive asymmetrical polyarthritis associated with hepatitis C virus (HCV), the optimal management approach is antiviral therapy (AVT) to eradicate the underlying HCV infection, combined with low-dose glucocorticoids and hydroxychloroquine for symptomatic relief of joint symptoms. 1

Diagnostic Considerations

Before initiating treatment, it's important to confirm the diagnosis and differentiate HCV-related arthritis from other conditions:

• HCV-related arthritis typically presents as one of two subtypes:

  • Symmetrical polyarthritis (RA-like) involving wrists and hands 1
  • Intermittent mono-oligoarthritis affecting medium and large joints, particularly ankles 1

• Key diagnostic features of HCV-related arthritis:

  • Non-erosive joint involvement 1
  • Absence of rheumatoid nodules 1
  • Negative anti-CCP antibodies (helpful in differentiating from RA) 1
  • Positive rheumatoid factor in >50% of cases 1
  • May be associated with cryoglobulinemia and its cutaneous manifestations 1

Treatment Algorithm

1. Etiologic Treatment (First-line)

• Antiviral therapy (AVT) should be initiated once HCV-related arthritis is diagnosed 1
  • Modern interferon-free direct-acting antiviral (DAA) regimens are preferred over older interferon-based therapies 1
  • Interferon-free regimens are likely more beneficial as interferon-alpha can sometimes worsen arthritis 1, 2

2. Non-Etiologic Treatment (Symptomatic Relief)

For symptom management while awaiting viral clearance or in cases with persistent joint symptoms:

• First-line options:

  • Low-dose glucocorticoids 1
  • Hydroxychloroquine 1, 2
  • NSAIDs/COXIBs for pain control 3, 2

• Second-line options (for more aggressive disease):

  • Rituximab (RTX) may be successfully employed in patients with more aggressive disease, particularly with cryoglobulinemia 1

• Medications to avoid or use with caution:

  • Methotrexate and leflunomide are often unnecessary or contraindicated due to potential hepatotoxicity 1, 2
  • Anti-TNF agents, while safe in HCV infection, are generally considered excessive for HCV-related arthritis due to its typically non-aggressive nature 1, 3

Special Considerations

• Patients with concomitant cryoglobulinemia may require more aggressive treatment, with rituximab being a first-choice treatment in this setting 1

• The course of HCV-related arthritis is typically less aggressive than rheumatoid arthritis:

  • Non-deforming 1, 3
  • Not associated with bone erosions 1, 4
  • May still cause significant morning stiffness and impact quality of life 4, 2

• Treatment response should be monitored by:

  • Clinical improvement in joint symptoms 4
  • Virological response (HCV RNA levels) 4, 2
  • Resolution of associated manifestations (e.g., cryoglobulinemia if present) 4

• For patients with hepatitis B virus (HBV) rather than HCV, antiviral therapy directed at HBV (e.g., tenofovir) has also been reported to improve polyarthritis 5
