++
Very rare genetic disorder diagnosed in infancy and
characterized by deafness (adolescence), nonpruritic urticaria, and renal
amyloidosis type AA. Other clinical features include arthralgias and/or
conjunctivitis.

Urticaria-Deafness-Amyloidosis Syndrome.
++
Fewer than 150 cases reported
since the first description in 1962. Autosomal dominant with variable
penetrance.
++
Most patients present with some or all of the
following manifestations: chronic urticaria, sensorineural deafness,
periodic arthritis, “aguey bouts.” “Aguey bouts” are composed of (a)
chills, rigors, and malaise; (b) aching pains in distal limbs and large
joints; and (c) urticarial rash over the whole body. Associated findings may
include renal amyloidosis (and renal insufficiency), aminoaciduria,
conjunctivitis, abdominal pain, angioedema, meningitis, and aphthous
ulceration of the buccal mucosa. Hyperglycinuria, and renal stones, as well
as renal amyloidosis, have been reported, but neither is required for the
diagnosis.
++
Evaluation of renal function if
indicated. Because attacks may be induced by cold, hypothermia should be
prevented. Renal function must be considered in the selection of anesthetic
agents.
