    Eradication of Helicobacter pylori (Hp) infection is strongly recommended in duodenal and gastric ulcer. In developed countries the recurrence rate is low; however, in Turkey, the Hp recurrence rate is suspected to be high as the prevalence of Hp infection is-as high as 70-80% in the asymptomatic population. We planned this study to determine the relapse rate of Hp infection after successful eradication therapy in Turkey. Fifty-two cases including 24 patients with duodenal ulcer and 28 patients with nonulcer dyspepsia were examined in this study. The eradication regimen was omeprazole 20 mg twice daily, clarithromycin 500 mg twice daily, and metronidazole 500 mg three times a day for 1 week. All patients underwent upper gastrointestinal tract endoscopy. At least four samples from antrum and corpus were taken to enable histologic diagnosis of Hp infection. After the eradication therapy, endoscopy was repeated at 1, 3, 6, and 12 months, and Hp-positive patients were dropped from study. With the use of this regimen, the Hp eradication rate was 92.3% (48/52). After the eradication of Hp infection, relapse rates were 6.97%, 27.5%, and 11.11% at 3, 6, and 12 months, respectively. The cumulative relapse rate for 1 year was 41.46%. The results of this study revealed that after the eradication of Hp infection, recurrence is encountered very often as a problem in Turkey. We concluded that hygienic and environmental factors can affect these high relapse rates.

    A rare complication of endoscopic injection sclerotherapy: Thrombosis of subclavian vein
    (H G E Update Medical Publishing, 2000) Gürel, Selim; Demir, Kadir; Kaymakoğlu, Sabahattin; Boztaş, Güngör; Çakaloğlu, Yılmaz; Beşişik, Fatih; Ökten, Atilla; Uludağ Üniversitesi/Tıp Fakültesi/Gastroenteroloji Anabilim Dalı.; AAD-9058-2020; AAT-2362-2020; AAT-3618-2020; 7003706434; 7004350992; 7004155395; 6602853371; 6603954907; 35501519800; 7005427442
    A 28-year-old man with compensated cirrhosis of the liver (Child B) and after 4 episodes of esophageal variceal bleeding received prophylactic endoscopic variceal sclerotherapy in our Gastroenterology Clinic for 8 consecutive months. Sclerotherapy of the esophageal varices had been performed at monthly intervals until variceal obliteration was achieved. Both the intravariceal and paravariceal injection techniques were used and injections were repeated periodically as necessary. On the 8th month, 1 week after the 4th sclerotherapy procedure, the patient complained of swelling on his right shoulder and on his right arm. There was jugular congestion and swelling of his right arm and right shoulder. The patient was hemodynamically stable. An X-ray of brachial venography revealed an obstruction of the vena subclavia dextra. During follow-up, the jugular congestion and swelling of his right arm gradually subsided spontaneously over a 6-month period without any need for medication. There has been no recurrence of his symptoms during the 1-year follow-up period. Now, he is still well clinically. This experience suggests that endoscopic injection sclerotherapy may cause thrombosis of the subclavian vein which have been never seen before.

    Background/Aims: This study aimed to evaluate the real-life efficacy and tolerability of direct-acting antiviral treatments for patients with chronic hepatitis C (CHC) with/without cirrhosis in the Turkish population.Material and Methods: A total of 4,352 patients with CHC from 36 different institutions in Turkey were enrolled. They received ledipasvir (LDV) and sofosbuvir (SOF)+/- ribavirin (RBV) ombitasvir/paritaprevir/ritonavir +/- dasabuvir (PrOD)+/- RBV for 12 or 24 weeks. Sustained virologic response (SVR) rates, factors affecting SVR, safety profile, and hepatocellular cancer (HCC) occurrence were analyzed.Results: SVR12 was achieved in 92.8% of the patients (4,040/4,352) according to intention-to-treat and in 98.3% of the patients (4,040/4,108) according to per-protocol analysis. The SVR12 rates were similar between the treatment regimens (97.2%-100%) and genotypes (95.6%-100%). Patients achieving SVR showed a significant decrease in the mean serum alanine transaminase (ALT) levels (50.90 +/- 54.60 U/L to 17.00 +/- 14.50 U/L) and model for end-stage liver disease (MELD) scores (7.51 +/- 4.54 to 7.32 +/- 3.40) (p<0.05). Of the patients, 2 were diagnosed with HCC during the treatment and 14 were diagnosed with HCC 37.0 +/- 16.0 weeks post-treatment. Higher initial MELD score (odds ratio [OR]: 1.92, 95% confidence interval [CI]: 1.22-2.38; p=0.023]), higher hepatitis C virus (HCV) RNA levels (OR: 1.44, 95% CI: 1.31-2.28; p=0.038), and higher serum ALT levels (OR: 1.38, 95% CI: 1.21-1.83; p=0.042) were associated with poor SVR12. The most common adverse events were fatigue (12.6%), pruritis (7.3%), increased serum ALT (4.7%) and bilirubin (3.8%) levels, and anemia (3.1%).Conclusion: LDV/SOF or PrOD +/- RBV were effective and tolerable treatments for patients with CHC and with or without advanced liver disease before and after liver transplantation. Although HCV eradication improves the liver function, there is a risk of developing HCC.
