Abstract

Background/aims: Helicobacter pylori-induced gastritis increases serum nitrate and nitrite concentrations. The relationship between splanchnic hemodynamics and nitrate and nitrite levels has been demonstrated. We aimed to determine the effect of Helicobacter pylori eradication treatment on portal hemodynamics. Methods: Nineteen patients with liver cirrhosis and Helicobacter pylori gastritis were included. Nine patients had esophageal varices indicating over portal hypertension. After histopathologic examination of gastric mucosa, Doppler ultrasonographic measurement of the portal veins and serum sampling to determine nitrate and nitrite concentration, treatment for Helicobacter pylori eradication was initiated for each patient. Evaluation of histopathology, Doppler measurements and sampling for serum nitrate and nitrite levels were repeated six weeks after the end of therapy. Results: The rate of eradication of Helicobacter pylori was 73.7%. The median inflammation score, Helicobacter pylori density, and the median serum concentration of nitrate and nitrite decreased significantly after therapy (p values were 0.021, 0.001, and 0.018, respectively). After treatment, the patients with varices showed significant decreases in serum nitrate and nitrite levels whereas those without varices did not. Considering portal measurements, alteration in the congestion index approached statistical significance (0.15 versus 0.1; p=0 .066) in the patient group with varices. Conclusions: Reducing effect of Helicobacter pylori eradication treatment on serum nitrate and nitrite concentration seems to have some beneficial influence on portal hemodynamics.

Özet

Amaç: Helikobakter pylori gastriti serum nitrat ve nitrit konsantrasyonunu artırmaktadır. Splanknik hemodinamiklerle serum nitrat ve nitrit seviyesi arasında ilişki olduğu gösterilmiştir. Helikobakter pilori eradikasyon tedavisinin portal hemodinamikler üzerindeki etkilerini incelemeyi amaçladık. Metod: Karaciğer sirozu ve Helikobakter pilori gastriti olan 19 hasta çalışmaya alındı. Dokuz hastada belirgin portal hipertansiyonu gösteren özofagus varisleri vardı. Gastrik mukozanın histopatolojik değerlendirmesi, portal venlerin Doppler ultrasonografik ölçümü ve nitrat ve nitrit konsantrasyonu için serum örneklemesi yapıldıktan sonra hastalara Helikobakter pilori eradikasyon tedavisi başlandı. Histopatoloji, Doppler ölçümleri ve serum nitrat ve nitrit seviyeleri tedavi bitiminden 6 hafta sonra tekrar değerlendirildi. Bulgular: Helikobakter pilori eradikasyon oranı %73,7 idi. Mukozanın inşamasyon skoru, Helikobakter pilori yoğunluğu ve serum nitrat ve nitrit konsantrasyonu tedavi sonrasında anlamlı biçimde azaldı (p değerleri sırası yla 0,021; 0,001 ve 0,018 idi). Tedaviden sonra serum nitrat ve nitrit seviyesi varisli olan hastalarda anlamlı azalma gösterirken varisi olmayanlarda anlamlı değişiklik olmadı. Portal ölçümler açısından konjesyon indeksindeki değişiklik varisli hasta grubunda istatistiki anlama yaklaştı (0,15’e karşılık 0,1; p=0,066). Sonuç: Helikobakter pilori eradikasyon tedavisinin serum nitrat ve nitrit konsantrasyonu üzerine azaltıcı etkisinin portal hemodinamikler üzerine faydalı etkileri olabilir.
