Abstract

Invasive pulmonary aspergillosis and zygomycosis are fungal opportunistic diseases with a high morbidity and mortality rate, predominantly affecting immunosuppressed patients. In patients with severe aplastic anemia (SAA) more than one invasive mycotic infection should be considered and early diagnosis with adequate treatment is crucial. We present a patient with treatment resistant SAA who developed zygomycosis while under caspofungin + voriconazole combined antifungal therapy for invasive pulmonary aspergillosis. A 13.5 year old boy with SAA developed invasive pulmonary aspergillosis. Liposomal amphotericin B (L-AmB) was started, but he developed an anaphylactic type hypersensitivity reaction with L-AmB. Therefore treatment was changed to voriconazole treatment, and at the 3rd month of this treatment, caspofungin was added as a salvage therapy. However, he did no respond to immunosuppressive treatment for SAA. No clinical or laboratory improvement of invasive fungal infection was seen in spite of antifungal therapy. Clinical nasal/ paranasal zygomycosis occurred and showed a very rapid spread to most parts of the face under this intensive antifungal therapy. Although no destruction of the bones was seen on tomography at first, a fungal infection was suspected and histopathologic / micologic cultures proved the diagnosis. L-AmB was given with a protocol allowing desensitization since the patient had a history of anaphylactic reaction. This case report is presented in order to illustrate the possibility of more than one fungal infection in an immuncompromised patient in spite of antifungal therapy and documenty a successful L-AmB challenge and possible desensitization in a patient with SAA who had a prior anaphylactic reaction associated with L-AmB.

Özet

İnvaziv pulmoner aspergillozis ve zigomikozlar, özellikle bağışıklık sistemi baskılanmış hastalarda morbidite ve mortaliteye neden olan fırsatçı mantar enfeksiyonlarıdır. Ağır aplastik anemili (AAA) hastalarda birden fazla invaziv fungal enfeksiyon olabileceğinin akılda tutulması, erken tanı ve uygun tedavi çok önemlidir. Tedaviye dirençli çok AAA’li hastada, invaziv pulmoner aspergillozise yönelik vorikonazol + kaspofungin kombine antifungal tedavisi verilirken gelişen zigomikoz enfeksiyonu sunuldu. AAA’li 13.5 yaşındaki erkek olguda invaziv pulmoner aspergillozis enfeksiyonu saptandı. Lipozomal amfoterisin B (L-AmB) başlandı. Ancak, hastada L-AmB tedavisi sırasında anaflaktik reaksiyon gelişti. Bu yüzden, antifungal tedavi vorikonazol olarak düzenlendi. Vorikonazol tedavisinin 3. ayında, kurtarma tedavisi amacıyla kaspofungin eklendi. AAA’li olguda immunsupresif tedaviye olumlu yanıt alınamadı. İkili antifungal tedaviye rağmen invaziv pulmoner aspergillozis enfeksiyonunda klinik ve laboratuar olarak iyileşme saptanmadı. İzleminde klinik olarak nasal/paranazal zigomikoz enfeksiyonundan kuşkulanıldı. Yoğun antifungal tedaviye rağmen enfeksiyon hızla maksiller bölgeye yayıldı. Enfeksiyon ilk başladığında çekilen tomografide kemik yapılarda destrüksiyon görülmemesine karşın histopatolojik ve mikolojik olarak zigomikoz teşhisi konuldu. L-AmB ile anaflaktik reaksiyon öyküsü nedeniyle L-AmB tedavisi, desensitizasyon ile birlikte başarılı bir şekilde verildi. İmmunsupresif hastalarda antifungal tedavi altında dahi birden fazla invaziv fungal enfeksiyon gelişebileceği, ayrıca L-AmB’ye alerjisi olan hastalarda başka tedavi alternatifi yoksa desensitizasyon ile L-AmB verilebileceğini vurgulamak amacıyla bu hasta sunulmuştur.
