Abstract

Objective: The spectrum of allergen sensitization differs widelybetween countries and also regions within the same country. Theaim of this study was to investigate the allergen sensitization patternsof atopic children who presented to our allergy clinic.Materials and Methods: The study retrospectively reviewed allchildren who presented to our clinic with a suspicion of allergicdiseases and had at least one allergen sensitization between January2014 and January 2017. Clinical diagnosis and atopy markers such astotal IgE, serum eosinophil counts, skin prick test (SPT), food andinhalant specific IgE results were evaluated.Results: A total of 1307 patients were evaluated. The mean ageof the children was 9.0±4.4 years and 61.9% were male. Allergicrhinitis was the most common diagnosis with a frequency of 38.9%,followed by asthma (32.9%), urticaria (15.9%) and atopic dermatitis(5.4%). Food mix specific IgE (fx5) positivity was present in 27.6%of patients. The rate of SPT positivity for food allergens was 8.3%.Eggs (4.4%), cow’s milk (2.3%) and peanut (1.7%) were found tobe the most common food allergens in SPT. Inhalant specific IgE(phadiatop) positivity was present in 83.0% of the patients. The mostcommon aeroallergens in SPT were Dermatophagoides pteronyssinus(67.9%), Dermatophagoides farinae (67.2%), Alternaria alternata(19.4%) and grass mix (17.7%). Polysensitization was found in 39.5%of the patients. One hundred and eighty seven (14.3%) patients hada negative phadiatop but positive SPT to inhalants. Among them,the most frequent allergens detected in SPT were mites (20.8%),Alternaria alternata (20.3%) and cockroach (11.8%). Among thosewith Alternaria monosensitization, the serum phadiatop test wasnegative in 50.8%. Conclusion: The distribution of allergen sensitizations in atopicchildren in Mersin province is reported for the first time. Alternariaalternata has emerged as a very important allergen that may be oftenmissed in phadiatop testing.

Özet

Amaç: Allerjen duyarlılığının spektrumu, ülkeler arasında ve aynı ülke içindeki bölgeler arasında büyük farklılıklar gösterir. Çalışmamızın amacı allerji kliniğimize başvuran atopik çocuklarda allerjen duyarlılığının dağılımını araştırmaktır. Gereç ve Yöntem: Ocak 2014 ile Ocak 2017 arasında allerjik hastalık şüphesiyle kliniğimize başvuran ve en az bir allerjen duyarlılığı olan çocuklar retrospektif olarak değerlendirildi. Klinik tanıları ve total IgE, serum eozinofil sayıları, deri prik testi (DPT), besin ve inhalan spesifik IgE sonuçları gibi atopi belirteçleri değerlendirildi. Bulgular: Çalışmada 1307 hasta değerlendirildi. Hastaların ortalama yaş 9.0±4.4 yıl ve %61.9’u erkekti. Allerjik rinit en sık saptanan tanı %38.9 olup, bunu astım (%32.9), ürtiker (%15.9) ve atopik dermatit (%5.4) izledi. Besin spesifik IgE (fx5) pozitifliği hastaların %27.6’sında mevcuttu. Besin allerjenleriyle DPT pozitifliği oranı %8.3 idi. DPT’de en sık saptanan besin allerjenleri yumurta (%4.4), inek sütü (%2.3) ve yer fıstığı (%1.7) idi. Hastaların %83’ünde inhalan spesifik IgE (phadiatop) pozitifliği mevcuttu. DPT’deki en sık saptanan aeroallerjenler Dermatophagoides pteronyssinus (%67.9), Dermatophagoides farinae (%67.2), Alternaria alternata (%19.4) ve çayır poleni (% 17.7) idi. Polisensitizasyon hastaların %39.5’inde saptandı. 187 (%14.3) hastada phadiatop negatifti ancak inhalanlarla DPT pozitifliği mevcuttu. Bu hastalar arasında, DPT’de en sık saptanan allerjenler akarlar (%20.8), Alternaria alternata (%20.3) ve hamamböceği (%11.8) idi. Alternaria monosensitizasyonu olanlar arasında ise phadiatop testi %50.8 oranında negatifti.Sonuç: Mersin ilindeki atopik çocuklarda allerjen sensitizasyon dağılımı ilk kez bildirildi. Alternaria alternata, phadiatop testiyle sıklıkla gözden kaçırılabilen oldukça önemli bir allerjen olarak ortaya çıkmaktadır.
