A case of multiple extrahepatic manifestations in a patient with untreated, chronic hepatitis C virus infection

Area of Science:

• Nephrology
• Hematology
• Immunology

Background:

• Chronic hepatitis C virus (HCV) infection is a systemic disease affecting multiple organs beyond the liver.
• Mixed cryoglobulinemia (MC) type 2 is a frequent extrahepatic complication of HCV, characterized by immunoglobulin complex deposition in blood vessels.
• This deposition triggers systemic inflammation, leading to diverse clinical manifestations across various organ systems.

Observation:

• A rare case involving a patient with cryoglobulinemia, cutaneous vasculitis, membranoproliferative glomerulonephritis, and B cell lymphoma was observed.
• The patient presented with a variant t(6;10) translocation.
• The complex clinical picture was associated with an untreated, chronic HCV infection.

Findings:

• The case illustrates a rare confluence of autoimmune phenomena and hematologic malignancy in the context of chronic HCV.
• The specific t(6;10) translocation in the B cell lymphoma adds a unique genetic dimension to the presentation.
• The interconnectedness of HCV infection, cryoglobulinemia, and multi-systemic disease manifestations is underscored.

Implications:

• This case underscores the diagnostic and management challenges posed by complex presentations of HCV-related extrahepatic complications.
• It highlights the importance of considering systemic HCV effects, including vasculitis and glomerulonephritis, in patients with unexplained multi-systemic disorders.
• Further research into the pathogenesis and optimal treatment strategies for such intricate cases is warranted.
