AA Amyloidosis and Atypical Familial Mediterranean Fever with Exon 2 and 3 Mutations
نویسندگان
چکیده
A 54-year-old Japanese man presented with recurrent abdominal pain, fever lasting >5 days, and renal failure. AA amyloidosis was proven by renal and gastric biopsy. Symptoms subsided with the administration of colchicine, but a subsequent recurrence of symptoms did not respond to colchicine. Mediterranean fever gene (MEFV) analysis showed that he was heterozygous for mutations in exon 2 (E148Q/R202Q) and exon 3 (P369S/R408Q), although he had none of the exon 10 mutations known to be closely related to AA amyloidosis. He did not respond to infliximab, but tocilizumab therapy was successful. The present case is a rare report of AA amyloidosis associated with familial Mediterranean fever in Japan.
