Abstract

Objective: Posaconazole is a recently developed wide-spectrum antifungal medication for which insufficient data is available regarding its potential pediatric use as a salvage therapy for systemic fungal infections in Turkey. The present study makes a retrospective review of the use of posaconazole as a salvage therapy. Material and Methods: The study included patients aged between 13 and 18 years who had undergone posaconazole salvage therapy for the treatment of invasive fungal infections (IFI) between 2010 and 2015. Demographical and clinical data was collected retrospectively from patient files. All patients were given the posaconazole active substance with the trade name Noxafil® in a 40 mg/mL oral suspension, divided into four doses of 800 mg/day. Results: Posaconazole salvage therapy was used in a total of six patients with a median age of 14.5 years (range 13-16 years), of which two had a primary immunodeficiency, and four had hematological malignancies. Antifungal therapy was initiated for proven, probable and possible IFI in one, four and one patients, respectively, of which five patients had lung involvement and one had central nervous system (CNS) involvement. Posaconazole was given to all patients in combination with another antifungal medications in a weight-based median dose of 5 mg/kg. Blood concentrations of the drug were not measured. Of the total, two patients responded completely to therapy and were switched to posaconazole prophylaxis treatment; posaconazole was switched with another antifungal agent in one patient who experienced progressive infection, and three patients whose primary disease was not under control died while receiving therapy for active fungal infections. Conclusion: A posaconazole oral suspension was used for the treatment of IFI in a complicated patient group, and a treatment success rate of 33 percent was recorded. It is possible that the target blood concentrations of the drug were not achieved, as the dosage used per kilogram body weight was relatively low and blood concentrations were not measured. As a result of problems associated with absorption and appropriate dosing of posaconazole in adolescents, it would appear to be a sensible approach to measure blood concentrations of posaconazole in order to ensure safe and effective therapy.

Özet

Giriş: Posakonazol yakın zamanda geliştirilmiş geniş spektrumlu bir an-tifungal ilaçtır. Ülkemizde çocuk yaş grubunda sistemik mantar enfeksi-yonlarının kurtarma tedavisinde kullanımı hakkında yeterli veri yoktur. Bu çalışmada, kurtarma tedavisi olarak posakonazol kullanımının geriye dönük olarak değerlendirilmesi amaçlanmıştır. Gereç ve Yöntemler: Çalışmaya 2010-2015 yılları arasında invaziv man-tar enfeksiyonu (İME) kurtarma tedavilerinde posakonazol kullanılan 13-18 yaş arası olgular dahil edildi. Demografik ve klinik bilgiler hasta dosyalarından geriye dönük olarak tarandı. Tüm olgularda posakonazol etken maddeli Noxafil® 40 mg/mL oral süspansiyon, 800 mg/gün dört bölünmüş dozda kullanıldı. Bulgular: Ortanca yaşı 14.5 yıl (aralık 13-16 yaş) olan toplam altı olgu-da posakonazol kurtarma tedavisi kullanıldı. İki olguda primer immün-yetmezlik, dört olguda ise hematolojik malignite saptandı. Bir olguya kanıtlanmış, dört olguya mümkün ve bir olguya da olası İME nedeniyle antifungal tedavi başlanmıştı. Beş olguda akciğer tutulumu, bir olguda merkezi sinir sistemi (MSS) tutulumu vardı. Posakonazol bütün olgular-da başka bir antifungal ilaç ile beraber verildi. Kilo bazlı ortanca doz 5 mg/kg/doz idi. İlaç kan düzeyi ölçülemedi. İki olguda tam yanıt alınarak posakonazol ile profilaksiye geçildi. Bir olguda enfeksiyonun ilerlemesi nedeniyle posakonazol başka bir anifungal ile değiştirildi. Primer has-talıkları kontrol altına alınamayan üç olgu aktif mantar enfeksiyonu ve tedavisi devam ederken kaybedildi. Sonuç: Posakonazol oral süspansiyon, komplike bir hasta grubunda İME kurtarma tedavisinde kullanılmış ve %33 oranında tedavi başarısı sağ-lanmıştır. Kilograma göre kullanılan dozlar görece düşük olduğundan ve ilaç kan düzeyi ölçülemediğinden hedef kan düzeylerine ulaşılama-mış olabilir. Emilim ve özellikle ergen yaş grubundaki dozaj sorunları nedeniyle posakonazolün güvenle ve etkin olarak kullanılabilmesi için beraberinde ilaç düzeyi ölçümünün yapılabilmesi gerekmektedir.
