Abstract

Epidemiological studies revealed increased gastric cancer risk in helicobacter pylori-infected cases and Helicobacter pylori-mediated oxidative DNA damage is suggested as responsible factor. In order to examine the effect of clarithromycin+ amoxicillin treatment on oxidative DNA damage in helicobacter pylori-infected cases, DNA damage in the basis of frequency of DNA strand breaks and formamidopyrimidine DNA glycosylase (fpg)-sensitive sites were determined before and after two weeks of treatment with clarithromycin (1 g/day) and amoxicillin (1 g/day). The frequency of fpg-sensitive sites determined by the comet assay was found to be decreased after the treatment (p<0.001) but frequency of DNA strand breaks was unchanged. Frequency of fpg-sensitive sites was found to be positively correlated with age (r: 0.59; p<0.05). Our data suggested that treatment of helicobacter pylori by clarithromycin +amoxicillin may prevent the helicobacter pylori-mediated gastric cancer risk by decreasing oxidative DNA damage in helicobacter pylori infected patients.

Özet

Epidemiyolojik çalışmalar helicobacter pylori ile enfekte kişilerde gastrik kanser oluşumunun enfekte olmayan kişilere göre daha yüksek olduğu göstermekte, bu durumdan helicobacter pylori-aracılı oksidatif DNA hasarının sorumlu olduğu düşünülmektedir. Helicobacter pylori ile enfekte vakalarda clarithromycin+amoxicillin tedavisinin oksidatif DNA hasarı üzerine etkisini incelemek amacıyla iki haftalık clarithromycin (1 g/gün)+amoxicillin (1g/gün) tedavisi öncesi ve sonrasında DNA hasarı DNA zincir kırıkları ve formamidoprimidin DNA glikozilaz (fpg)-duyarlı bölgeler bazında belirlendi. Comet yöntemi ile ölçülen fpg-duyarlı bölgelerin sıklığının tedavi sonrasında azaldığı (P<0.001) ancak DNA zincir kırıkları sıklığının değişmediği saptandı. fpg-duyarlı bölgelerin sıklığının yaşla pozitif korelasyon gösterdiği belirlendi (r: 0.59; P<0.05). Bulgular helicobacter pylori ile enfekte kişilerde clarithromycin +amoxicillin tedavisinin oksidatif DNA hasarını azaltmak yoluyla helicobacter pylori-aracılı mide kanseri oluşum riskini azaltabileceğini göstermektedir.
