Tracheobronchial amyloidosis managed with multimodality therapies

Abstract: Amyloidosis is a systemic disease involving abnormal extracellular deposition of amyloid and autologous fibrillar protein material in β-pleated sheets. Accumulation of this abnormal protein leads to organ dysfunction, although respiratory tract involvement is rare. We present two cases of tracheobronchial amyloidosis successfully treated with surgery and radiation.

“…Some series reports mortality in up to 75% within 6 years from diagnosis, while in others no mortality is reported in the 7.6-year average follow-up [7]. The estimated 5-year survival for the diffuse TBA disease is 30-50% [5,13]. Our patient remained asymptomatic for 10 years from initial diagnosis; this evolution has been reported in some cases [5,14].…”

“…In our patient, due to her excellent response to colchicine treatment, no further therapies were needed. The proximal tracheal and subglottic disease that she presented, as well as diffuse TBA disease, are known to have a poorer prognosis [10,13]; nevertheless, she has continued to be asymptomatic in the last 4 years.…”

“…Während in einigen Fallserien von Mortalitätsraten von bis zu 75% innerhalb von 6 Jahren ab der Diagnosestellung berichtet wird, verzeichnen andere keinen einzigen Todesfall in einem durchschnittlichen Nachbeobachtungszeitraum von 7,6 Jahren [7]. Die 5-Jahres-Überlebensrate bei der diffusen Form von TBA wird auf 30-50% geschätzt [5,13]. Unsere Patientin blieb bis 10 Jahre nach der Erstdiagnose symptomfrei; eine solche Entwicklung ist auch in anderen Fällen beschrieben worden [5,14].…”

“…Bei unserer Patientin waren angesichts ihres hervorragenden Ansprechens auf das Colchicin keine weiteren Behandlungsmaßnahmen erforderlich. Von der proximal-trachealen und subglottischen Erkrankung, die bei ihr vorlag, ist ebenso wie von der diffusen Form der TBA bekannt, dass sie mit einer schlechteren Prognose assoziiert sind [10,13]; dennoch ist die Patientin seit 4 Jahren durchgängig symptomfrei.…”

“…Amiloidoz tanısında Kongo kırmızısı (KK-Kongo red) boyama yöntemi altın standarttır ve tanı için boyanan biri-kimlerin ışığı çift kırması şarttır [3]. Solunum yolu tutulumu primer amiloidozda nadir görülür [1]. Solunum yollarının tutulumu primer amilodizisin tek bulgusu olabileceği gibi, sistemik hastalığın bir parçası da olabilir.…”
