Multineuropathy in a patient with HBV infection, polyarteritis nodosa and celiac disease.

We report on the first association of celiac disease, polyarteritis nodosa and HBV infection in a patient who developed a neuropathy. On admission his general and neurological conditions were severely compromised. Haematological test revealed HBV infection and high levels of antibodies to tissue transglutaminase, endomysium, gliadin. EMG showed sensory-motor asymmetric axonal neuropathy. A sural nerve biopsy revealed fibre loss, axonal degeneration with asymmetrical distribution and fascicular ischaemia. A duodenal biopsy was consistent with celiac disease. The patient was treated with immunosuppressive and antiviral therapy, and gluten-free diet with good result. Celiac disease can be related to a higher risk of autoimmune disorders and may have contributed to the development of multineuropathy in this patient.
