Giriş: Yetişkinlerde ağır formları görülmekle birlikte, Helicobacter pylori
(H. pylori) enfeksiyonu genellikle çocukluk çağında kazanılır. Bu nedenle,
çocukluk çağında H. pylori enfeksiyonunun erken tanısı çok önemlidir. Bu
çalışmada, H. pylori enfeksiyonu tanısında 13C üre nefes testinin (ÜNT)
duyarlılığını ve özgüllüğünü bulmayı, delta değeri (DOB) ile hastalığın şiddetini
değerlendirmeyi amaçladık.
Gereç ve Yöntem: Epigastrik ağrı ve/veya bulantı şikayeti ile başvuran 200
çocuğa UBT uygulandı. Hastalara özofagogastroduodenoskopi (ÖGD) yapıldı.
ÜNT sonuçları histopatolojik bulgularla karşılaştırıldı. ROC eğrisi analizi ile H.
pylori enfeksiyonunun şiddeti için bir belirleyici DOB değeri bulundu.
Bulgular: Yaş ortalaması 13,50±2,98 yıl olan 193 hasta araştırmaya alındı. Bu
hastaların 71’i (%36,8) ÜNT pozitif, 122’si (%63,2) negatif olarak tespit edildi.
ÜNT pozitif olan 71 hastanın 60’ına, ÜNT negatif olan 122 hastanın 30’una ÖGD
yapıldı. ÜNT’nin duyarlılığı %85,1, özgüllüğü %100 tespit edildi. Orta/belirgin
H. pylori yoğunluğu için DOB kesim değeri %6 olarak bulundu.
Sonuç: DOB değerleri ile H. pylori yoğunluğu ve enflamatuar aktivite arasındaki
pozitif korelasyon, hastalığın şiddetini tespit etmek için bir avantaj olabilir.

Importance of Delta Over Baseline Values in Predicting the Severity of Helicobacter pylori Infection in Children

Öz

Introduction:Although severe forms of the disease are seen in adults, the Helicobacter pylori (H. pylori) infection is usually acquired during childhood.
Therefore, prompt diagnosis of H. pylori infection in childhood is of prime importance. In the present study, we aimed to identify the sensitivity and specificity
of 13C urea breath test (UBT) in the diagnosis of H. pylori infection and to assess the severity of the disease with delta over baseline (DOB) values.

Materials and Methods: UBT was administered to 200 children who presented with epigastric pain and/or nausea. Esophagogastroduodenoscopy (EGD) was
performed in patients. UBT results were compared with histopathological findings. In the Area Under the ROC Curve analysis, a cutoff DOB value was found for the
severity of H. pylori infection.

Results: 193 children with a mean age of 13.50±2.98 years were included in the analysis. Of these, 71 (36.8%) patients had a positive UBT and 122 (63.2%) had a
negative UBT. EGD was performed in 60 out of 71 patients with positive UBT and in 30 out of 122 patients with negative UBT. The sensitivity and specificity of UBT
were 85.1% and 100%. DOB was found to be a significant predictor of moderate/marked H. pylori density at a cutoff value of 6%.

Conclusions: The positive correlation detected between the level of DOB values and the density of H. pylori and inflammatory activity can be an advantage for
detecting the severity of disease
