Two diseases one remedy? Systemic amyloidosis secondary to hidradenitis suppurativa: Treatment with infliximab.

ABSTRACT

Hidradenitis suppurativa, known as acne inversa, is a relapsing and chronic inflammatory skin disease affecting the skin folds. During the chronic course of the disease many local complications like fistulae to other tissues or systemic complications including anemia, secondary amyloidosis, lymphedema, nephrotic syndrome, artropathy may take place. Amyloid A amyloidosis is a rare complication of hidradenitis suppurativa, which has been described in a limited number of case reports. Herein, we present such a patient that had developed AA amyloidosis during the course of hidradenitis suppurativa. Both AA amyloidosis and hidradenitis suppurativa have responded to infliximab therapy which was shown by clinical recovery and by the improvement in renal functions.
