Case of cryoglobulinaemia associated with chronic hepatitis B
We present a case of a woman in her 50s with chronic hepatitis B (CHB) who had a longstanding history of arthralgia and swollen joints associated with severe fatigue. Investigations were consistent with a diagnosis of hepatitis B virus (HBV)-related cryoglobulinaemia. Two months after treatment with tenofovir alafenamide, an antiviral therapy for HBV, there was a significant improvement of her symptoms and undetectable serum cryoglobulins. Cryoglobulinaemia is a relatively rare extrahepatic manifestation of HBV infection and only presents in about 2%-4% of the patients with CHB. Its clinical manifestations include purpura, renal dysfunction, arthralgias and neuropathy. Since the presentation of cryoglobulinaemia in CHB can be non-specific, one needs to have a high index of suspicion to avoid delay in diagnosis and treatment.
