The relationship between Helicobacter pylori CagA IgG positivity and gastrointestinal complaints and histopathological findings
Abstract
Background and Aims: In recent years, there has been a
widespread use of serologic tests based on detection of IgG-type antibodies
against Helicobacter pylori CagA outer membrane protein, which is a strong
immunogen and cytotoxin, for the identification of pathologies caused by these
microorganisms. The aim of this study was to evaluate the relationship between
CagA IgG antibodies against Helicobacter pylori and gastrointestinal complaints
and histopathological and demographic data. Material and Methods: This study included 74 adult patients
who were admitted to the internal medicine outpatient clinic with different
gastrointestinal complaints, showed Helicobacter pylori positivity in the urea
breath test, and underwent esophagogastroduodenoscopic biopsy because of the
diagnosis. The presence of IgG antibodies against CagA protein was
detected by Enzyme Linked Immunosorbent Assay. Results: The 74 patients included 20 (27%) females and 54
(73%) males. CagA IgG positivity was detected in 62% of the Helicobacter
pylori-positive patients. The most common gastrointestinal complaint was
abdominal pain, and the most common histopathological finding was chronic
active gastritis in the CagA IgG-positive patient group. Conclusion: Further long-term studies with a large sample
size are needed to standardize the use of these serologic tests, which are
inexpensive, practical, and noninvasive, in the early diagnosis of pathologies
associated with Helicobacter pylori infection.

Helicobacter pylori CagA IgG pozitifliğinin gastrointestinal yakınmalar ve histopatolojik bulgular ile ilişkisi
Abstract
Giriş ve Amaç: Güçlü immünojen ve sitotoksin olan Helicobacter
pylori CagA
dış membran proteinine karşı
oluşan IgG tipi antikorların tespitine dayanarak yapılan serolojik testlerin,
bu mikroorganizmaların neden olduğu patolojilerin tespitinde kullanımı son
yıllarda yaygınlaşmaktadır. Bu çalışmada, Helicobacter
pylori’ye karşı oluşmuş
CagA IgG antikorlarının gastrointestinal yakınmalar, histopatolojik ve demografik
veriler ile ilişkisinin
değerlendirilmesi amaçlandı. Gereç ve Yöntem: Farklı gastrointestinal yakınmalar ile
dahiliye polikliniğine başvurduktan sonra rutin değerlendirmelerinde üre nefes
testi ile Helicobacter pylori açısından pozitif olarak tespit edildikten sonra tanı amaçlı özofagogastroduodenoskopik biyopsi yapılan18
yaş üzeri toplam 74 hasta çalışmamıza dahil edildi. Bu hastalarda CagA proteinine ait özgül IgG antikor varlığını saptamak için Enzyme Linked Immunosorbent Assay yöntemi
kullanıldı. Bulgular: Yetmişdört hastanın 20’si kadın (%27) ve 54’ü erkekti (%73). Helicobacter pylori pozitif saptanan
hastaların %62’sinde CagA IgG pozitifliği saptandı. CagA
IgG pozitif hasta
grubunda en sık saptanan gastrointestinal şikayet karın ağrısı ve en sık
histopatolojik bulgu kronik aktif gastrit olarak tespit edildi. Sonuç: Helicobacter pylori enfeksiyonu
ile ilişkili patolojilerin erken tanısında daha
ucuz, pratik ve invaziv olmayan bu serolojik
testlerin kullanımının standardize edilmesi için uzun dönemli ve büyük örneklem
büyüklüğüne sahip çalışmaların yapılmasına ihtiyaç vardır.
