Abstract

Sirolimus is a maintenance immunosuppressive agent after renal transplantation. Interstitial pneumonitis due to sirolimus which had no identified infectious etiology has been recently reported. We describe a case of recurrent sirolimus associated interstitial pneumonitis after renal transplantation, on the basis of its mechanism of action. The diagnosis of sirolimus-associated pulmonary toxicity was made after an exhaustive work-up to exclude infectious causes and other pulmonary disease. Sirolimus discontinuation resulted in clinical and radiologic improvement of interstital pneumonitis within 2 weeks. The precise etiology underlying sirolimus-induced pneumonitis remains unknown. However, observations in animals and humans indicate that this agent may cause lung injury in selected cases via differential regulation of the Th1/Th2 lymphocyte balance. We thought that bronchoalveolar lavage cell counts may provide some information about the mechanism of sirolimus-induced pneumonitis.

Özet

Sirolimus renal transplantasyon sonrasında idame tedavide kullanılmakta olan bir immunsupresif ajandır. Herhangi bir infeksiyöz etyolojinin saptanmadığı sirolimusa bağlı interstisyel pnömoni yakın zamanda bildirilmiştir. Renal transplantasyon sonrası sirolimus ile ilişkili rekürren interstisyel pnömoni geçiren bir olguyu, etki mekanizmasını temel alarak tanımladık. Bu vakada, sirolimus ile ilişkili interstisyel pulmoner toksisite tanısı, infeksiyöz nedenleri ve diğer pulmoner hastalıkları dışlamak için yapılan ayrıntılı değerlendirme sonrasında konulmuştur. Sirolimus tedavisinin kesilmesi iki hafta içerisinde interstisyel pnömonide klinik ve radyolojik düzelme ile sonuçlanmıştır. Sirolimus ile ilişkili olarak ortaya çıkan interstisyel pnömoninin kesin etyolojisi bilinmemektedir. Bununla birlikte, hayvan ve insanlarda yapılan araştırmalar bu ajanın seçilmiş vakalarda Th1/Th2 lenfosit oranında değişiklikler meydana getirelerek akciğer hasarına neden olabileceğini göstermektedir. Bronkoalveolar lavaj hücre sayımlarının, sirolimus ile ilişkili interstisyel pnömoninin mekanizması ile ilgili bilgi sağlayabileceğine düşünmekteyiz.
