A Devastating Case of Hepatitis C-Induced Mixed Cryoglobulinemia

Area of Science:

• Hepatology
• Immunology
• Vascular Medicine

Background:

• Hepatitis C virus (HCV) infection is a significant cause of chronic liver disease worldwide.
• Mixed cryoglobulinemia is a rare immune complex-mediated vasculitis associated with chronic HCV infection.
• This condition can lead to severe systemic complications, including critical limb ischemia.

Observation:

• A 55-year-old male with untreated chronic HCV presented with arthralgia and palpable purpura.
• The patient rapidly developed severe, life-threatening gangrene affecting all extremities.
• This critical presentation necessitated multiple amputations due to mixed cryoglobulinemia.

Findings:

• Initiation of treatment for chronic hepatitis C virus infection led to the cessation of gangrene progression.
• The patient's survival was achieved through timely antiviral therapy targeting the underlying HCV infection.
• Mixed cryoglobulinemia associated with HCV can manifest as rapidly progressive, severe peripheral gangrene.

Implications:

• Early diagnosis and treatment of HCV are vital to prevent severe vasculitic complications like gangrene.
• Direct-acting antiviral (DAA) therapy should be considered promptly in patients with HCV-associated cryoglobulinemia.
• Universal screening for HCV may facilitate earlier detection and intervention, averting catastrophic outcomes such as limb loss.
