Abstract

Objective: The objective of this study was to determine the prevalence of IgG antibodies against mumps in a representative stratified sample of children under 18 years of age in Pleven district, Bulgaria. Study Design: Cross sectional study. Materials and Methods: A cross-sectional, sero-epidemiologic survey of 132 children aged under 18 years was conducted in Pleven district. They were distributed into two age groups: from 0 to 11 years old (n=80) and from 12 to 18 years old (n=52). An enzyme immunoassay (EIA) was performed for indirect evidence of specific IgG antibodies in the serum. Results: The results showed that 41% of the investigated children were negative in terms of mumps IgG antibodies, 11% had borderline values and the remaining, approximately 48%, were positive. In the group of children aged 0 to 11 years who had received one dose of the mumps vaccine, 50% were negative for mumps IgG antibodies. In the second group of children aged 12 to 18 years who had received two vaccine doses, the percentage of participants negative for mumps IgG antibodies decreased significantly. Conclusion: Our observations emphasise the need to conduct expanded sero-epidemiological investigations of the populations most affected by mumps and to immunise susceptible individuals. Turkish Başlık: 18 Yaş Altı Bulgar Çocuklarda Kabakulak IgG Antikorlarının Seroprevalansı Anahtar Kelimeler: Kabakulak, seroprevalans, immünizasyon Amaç: Bu çalışmanın amacı Bulgaristan Plevne bölgesinde, 18 yaş altı çocukların temsil edici tabakalandırılmış bir örnekleminde, kabakulak IgG antikorlarının prevalansını saptamaktır. Çalışma tasarımı: Kesitsel çalışma. Materyal ve Metot: Plevne bölgesinde 18 yaş altı 132 çocukta kesitsel, sero-epidemiyolojik tarama yapıldı. Çocuklar iki yaş grubuna ayrıldı: 0 ila 11 yaş (n=80) ve 12 ila 18 yaş (n=52). Serumda spesifik IgG antikorlarının indirekt tayini için enzim immunoassay (EIA) yapıldı. Bulgular: Bulgular araştırılan çocukların %41'inde kabakulak IgG antikorlarının negatif olduğunu, %11'inin sınır değere sahip olduğunu ve kalan yaklaşık %48'inin pozitif olduğunu gösterdi. Bir doz kabakulak aşısı yapılmış olan, yaşları 0 ila 11 yıl olan çocuk grubunda %50'sinde kabakulak IgG antikorları negatif idi. İki aşı dozu almış olan, yaşları 12 ila 18 yıl olan ikinci grup çocuklarda kabakulak IgG antikorları negatif olan katılımcıların oranı belirgin olarak azdı. Sonuç: Gözlemlerimiz, çoğu kabakulaktan etkilenmiş olan popülasyonun yaygın sero-epidemiyolojik araştırmasının yapılmasına ve duyarlı kişilerin bağışıklanmasına gereksinimi vurgulamaktadır.
