Rheumatologic manifestations during chronic viral hepatitis C

Area of Science:

• Hepatology
• Rheumatology
• Systemic Diseases

Background:

• Chronic hepatitis C (CHC) is recognized as a systemic disease due to its diverse extrahepatic manifestations.
• Rheumatological issues are among the most common extrahepatic complications of CHC.

Purpose of the Study:

• To investigate the prevalence and characteristics of rheumatological manifestations (RM) in patients with CHC.
• To identify factors associated with RM in the CHC population.

Main Methods:

• A retrospective study analyzed 204 CHC patients over 11 years (2002-2012).
• Patients with hepatitis B or HIV co-infection or decompensated cirrhosis were excluded.
• Data collected included epidemiological, clinical, biological, immunological, virological, and histological information.

Main Results:

• Rheumatological manifestations (RM) were present in 37.25% of CHC patients.
• The most common RM were inflammatory polyarthralgia (88.15%), myalgia (14.47%), and dryness syndrome (22.36%).
• RM were associated with other extrahepatic manifestations, particularly mixed cryoglobulinemia (MC) (60%). Female sex and MC presence correlated significantly with RM.

Conclusions:

• RM are frequent in CHC, predominantly presenting as arthralgia, myalgia, and dry syndrome.
• True arthritis is uncommon but can be diagnostically challenging.
• Mixed cryoglobulinemia is the key immunological factor associated with RM, and antiviral therapy is the primary treatment approach.
