Hepatitis C virus (HCV) infection can cause autoimmune arthritis, often resembling rheumatoid arthritis (RA). Early diagnosis and specific treatments are crucial for managing HCV-related joint inflammation.

Area of Science:

  • Rheumatology
  • Infectious Diseases
  • Immunology

Background:

  • Hepatitis C virus (HCV) infection is linked to autoimmune disorders, including arthritis.
  • HCV-related arthritis presents non-erosive patterns, primarily RA-like polyarthritis and mono-oligoarthritis.
  • The mono-oligoarticular form is associated with serum cryoglobulins and an intermittent course.

Purpose of the Study:

  • To highlight the importance of considering HCV-related arthritis in differential diagnoses of inflammatory joint conditions.
  • To discuss diagnostic markers and treatment strategies for HCV-induced arthritis.
  • To evaluate the association between psoriatic arthritis (PsA) and HCV infection.

Main Methods:

  • Review of clinical patterns and diagnostic approaches for HCV-related arthritis.

  • Analysis of serological markers like antikeratin antibodies and IgA RF for differentiation.
  • Assessment of treatment outcomes with NSAIDs, hydroxychloroquine, corticosteroids, and antiviral therapies.

    • Main Results:

    • HCV-related arthritis requires consideration in patients with inflammatory joint involvement due to its variable presentation.
    • Antikeratin antibodies and IgA RF show high specificity in distinguishing RA from HCV-related RA-like polyarthritis.
    • The study could not confirm a confirmed association between psoriatic arthritis and HCV infection.

    Conclusions:

    • Wider screening for HCV antibodies is recommended in the diagnostic workup of rheumatic diseases.
    • Standard treatments include NSAIDs, hydroxychloroquine, and low-dose corticosteroids.
    • Antiviral therapy (alpha-interferon, ribavirin) is indicated for hepatic/systemic involvement and selected refractory arthritis cases.
