Dört yaþýndaki bir çocukta nadir bir anafilaksi nedeni: Muz ile oral provokasyon testi

Amaç: Besin alerjisi çocuklarda anafilaksinin en sýk nedenidir ve çalýþmalar son yýllarda besin alerjisinin sýklýðýnýn arttýðýný göstermektedir. Besinler arasýnda, meyveler nadiren anafilaksi nedeni olarak yer almaktadýr. Muz alerjisi eriþkinler içinde anaflaksi nedenleri içinde saptanmýþ olmasýna raðmen, çocuklarda bildirilen muz anaflaksisi olgularý oldukça azdýr. Bu olgu sunumunda muz alýmý sonrasýnda geliþen bir anaflaksi olgusu tartýþýldý.
Olgu: Dört yaþýndaki erkek hasta, muz alýmý sonrasý vücudunda yaygýn kaþýntý, ürtikeryal döküntü ve göz kapaklarýnda þiþlik ile baþvurdu. Tanýnýn kesinleþtirilmesi amacýyla yapýlan muz ile oral provokasyon testinde ürtikeryal papül saptandý. Muz verildikten 10 dakika sonra gövdesinde ürtiker, göz kapaklarýnda þiþlik ve hýrýltý þikayeti geliþti, dinlemekle bilateral ronküs mevcuttu ve hastanýn ölçülen tansiyonu normaldi. Hastaya anafilaksi tanýsý konuldu ve 0.01 mg/kg dan IM adrenalin, nebulizatör ile kýsa etklili beta 2 agonist ve anti histaminik tedavisi verildi. Ýzlemde bulgularý düzelen hasta antihistaminik ve 3 günlük oral metilprednizolon tedavisiyle taburcu edildi. Hastaya önerilerde bulunuldu ve adrenalin otoenjektör reçete edilip kullanýmý gösterildi.
Sonuç: Nadir de olsa çocuklarda muz ile anafilaksi geliþebilmektedir. Bu nedenle taný amaçlý yapýlacak oral provokasyonlar deneyimli merkezlerce yapýlmalý ve geliþebilecek reaksiyonlara karþý gerekli önlemler alýnmalýdýr.
