BackgroundThe H. pylori eradication success is low in countries with high antibiotic resistance to H. pylori. ObjectiveWe retrospectively assessed the eradication rates achieved by five different regimens and aimed to compare the efficiency of bismuth enhanced sequential therapy and other treatments in a gastroenterology outpatient clinic a university-affiliated hospital. DesignOur study was carried out with a retrospective cohort design. SettingThis study assessed the gastroscopy examinations of patients. PatientsA total of 621 patients were included in the study. There were 122 patients in the quadruple treatment group, 168 patients in the classical sequential treatment group, 130 patients in the bismuth enhanced sequential therapy, 113 patients in the sequential treatment with levofloxacin, and 88 patients in the hybrid treatment. MeasurementsEradication rates of different regimens was analyzed by performing Chi-square and Tukey's honest significant difference test. ResultsEradication rates by ITT and PP analysis achieved by treatment groups were 74.6 and 75.6% in the quadruple treatment; 70.2 and 70.4% in the sequential treatment with clarithromycin, 88.5 and 90.3% in the bismuth enhanced sequential therapy, 77.9 and 78.5% in the sequential treatment with levofloxacin, and 76.1 and 76.2% in the hybrid treatment. LimitationsThe main limitation of our study was its retrospective nature. Different proton pump inhibitors were used in the treatment arms. ConclusionsBismuth-enhanced sequential therapy can be recommended to overcome resistance.

(2016) Unler, Gulhan Kanat; Gokturk, Huseyin Savas; Dogan, Rusina; Kivanc, Tulay; Karakoca, Aydin; 0000-0003-0182-002X; 0000-0001-6503-3872; 27821023; AAG-3273-2020
Background and aims: The use of anesthetic agents for endoscopic sedation has recently increased. However, sedation introduces additional risks in patients with obstructive sleep apnea syndrome (OSAS). The presence of sleep apnea is not often enough questioned in clinical practice. The purpose of this study was to determine whether patients with sedation-induced snoring and decreased arterial oxygen saturation during gastroscopy are more likely to have OSAS. Methods: This study considered 600 consecutive patients undergoing elective outpatient upper gastrointestinal endoscopy under conscious sedation for evaluation of dyspepsia. Ten patients with observed snoring and decreased arterial saturation during the gastroscopy procedure were enrolled in the study. The control group was comprised of 13 patients matched by sex, age, and body mass index (BMI) who did not snore and had a more stable oxygen saturation under conscious sedation during an elective outpatient gastroscopy for the evaluation of dyspepsia and were selected using a computer-generated randomized sequence. Patients were monitored and an overnight polysomnography was performed in the study group. Statistically significant differences between groups were assessed using the nonparametric Wilcoxon and independent-samples t-tests. Results: There was no significant difference in age or BMI between the two groups (p>0,05) Mean minimum oxygen saturation was significantly different between the two groups (p=0.011). In the study group, 7 patients were found to have moderate OSAS necessitating a continuous positive airway pressure device. Conclusion: Patients with hypoxia and snoring, under conscious sedation are more likely to have OSAS. "Out-of-operating-room" sedoanalgesia is therefore critical.

(2016) Unler, Gulhan Kanat; Gokturk, Huseyin Savas; Toprak, Erzat; Erinanc, Ozgur Hilal; Korkmaz, Huseyin; https://orcid.org/0000-0003-0182-002X; https://orcid.org/0000-0002-2877-1232; https://orcid.org/0000-0003-1401-6356; 26897266; ABI-5902-2020; AAL-1268-2021
Introduction: Endometrial polyps (EPs) and colorectal polyps (CPs) are common disorders and the incidence of both increase rapidly with aging. CPs are focal lesions and incidence increases with age. Aim: In this study, we aimed to analyze retrospectively the relationship between the EPs and CPs sharing similar clinical and genetic factors in their etiopathogenesis. Materials and Methods: This study was retrospectively performed between 2010 and 2013 and it included patients diagnosed to have eEPs. The study group and the control group consisted of patients who were diagnosed with or without EPs and who underwent colonoscopy at the same period. Results: The study group was formed by 57 patients with diagnosis of EP who underwent colonoscopy during the same period. The control group consisted of 71 patients without EP examined with colonoscopy. Among 128 patients assessed in this study, 24 were diagnosed with CPs, all of which were adenomatous polyps smaller than 1 cm. No hyperplastic or inflammatory polyps were diagnosed. While 18 of 57 patients with EPs had CPs, 6 of 71 control subjects had CPs. Hence, the risk of having CP was 5 times greater in patients with EP compared to those without (P < 0.05). Conclusion: The present study demonstrated that the prevalence of CPs increased significantly in postmenopausal patients with EPs. Recommending colonoscopy to these patients irrespective of age may be beneficial for detecting more CPs and preventing colorectal cancer.
Does the Urea Breath Test Predict Eradication of Helicobacter Pylori Infection
(2016) Unler, Gulhan Kanat; Ozgur, Gulsum Teke; Gokturk, Huseyin Savas; Durukan, Elif; Erhamamci, Seval; https://orcid.org/0000-0003-0182-002X; https://orcid.org/0000-0002-8579-5564; 26852756; AAJ-8621-2021
Background/Aim : Helicobacter pylori infection is common world-wide and has been linked to development of gastric and duodenal ulcers, gastric adenocarcinoma, and gastric lymphoma. However, antimicrobial resistance has decreased H. pylori eradication rates worldwide. This study aimed to evaluate the effect of-bacterial load on eradication rate. Method : This prospective study included 237 consecutive patients who presented to our institution with dyspeptic symptoms and underwent both upper endoscopy and urea breath tests (UBT). The patients were divided into three equal sized groups according to their UBT values. All subjects received a standard triple eradication regimen, followed by a bismuth-based quadruple eradication regimen if triple eradication was not successful. The three groups were compared with respect to age, endoscopic findings, sex, and eradication rates. Results : Our results were consistent with those of previous studies : higher UBT values were associated with failure of standard 14-day triple treatment (p < 0.05). However, in patients who received a quadruple eradication regimen, differences between groups were not significant (p = 0.434). There was no relationship between UBT values and gastric pathologies (p = 0.751). Age and sex also did not differ significantly between groups (p = 0.061). Conclusions : Our study and others have found that high bacterial loads are negatively associated with achievement of eradication with triple treatment. However, differences between groups were not significant in patients who received a quadruple eradication regimen. Comparisons of treatment results according to bacterial density may be informative. The importance of H. pylori density should be further evaluated with new treatment protocols.

(2019) Erinanc, Hilal; Unler, Gulhan Kanat; Gokturk, Huseyin Savas; Ozgur, Gulsum Teke
Objective: Gastric polyps accounts for %6 of gastrointestinal endoscopy. Geographical differences occur in the prevalence of them. We aimed to determine the spectrum of gastric polyps. Matherial and method: Data including demographics, medical history and histological characteristics of polyps and Helicobacter pylori were obtained retrospectively. Results: Of the 24568 endoscopies performed, 184 patients were identified as having gastric polyps. The most frequently encountered were hyperplastic polyps (62%), followed by fundic gland polyps (19,3%) and adenomatous polyps (3, 8%). The corpus (36,4 %) was the most common site and the antrum (25%) was the second. Female patients were more affected than male patients (64,7%). Majority of the polyps (88%) were smaller than 1 cm in diameter. The mean age was 62,10+13,4 (range:30-90) years. Fundic gland polyps were observed at younger age (mean age: 56,58) compared to other gastric polyps. Intestinal metaplasia was more frequently encountered in hyperplastic polyps than in fundic gland polyps. Conclusion: In this study, hyperplastic polyps are the most common in our population however there was no association between the hyperplastic polyps and H. pylori infection. H. pylori infection ratio was similar in both hyperplastic polyps and fundic gland polyps however all of the patient have chronic gastritis. This findings suggest chronic gastritis also play role in hyperplastic polyps development. The study also showed that H. Pylori infection is still common in our country and further studies need to find efficacy of H.pylori treatment.
Is there any association between colonic polyps and gastric intestinal metaplasia?
(2016) Unler, Gulhan Kanat; Ozgur, Gulsum Teke; Gokturk, Huseyin Savas; Korkmaz, Huseyin; Erinanc, Ozgur Hilal; 27210777
Background/Aims: Chronic gastritis progression is a multistep process of atrophy, intestinal metaplasia (IM), and dysplasia, which may lead to invasive carcinoma. In this study, we identified an association of colonic polyps with gastric IM in patients undergoing colonoscopy. Materials and Methods: This retrospective case-control, cross-sectional study was conducted in a tertiary-care institution in Turkey. Pathology and endoscopy reports were reviewed. The study group comprised 400 patients with colonic adenomatous polyps, and the control group comprised 360 patients without colonic adenomatous polyps on colonoscopy. Results: The risk of gastric IM was 1.42-fold higher in the study group (p<0.05). The risk of IM in patients aged >= 50 years with colonic polyps was 3.35-fold higher than in those aged <50 years (p<0.05). The risk of Helicobacter pylori infection in the study group was 1.07-folder higher than that in the control group (p<0.05). H. pylori infection prevalence was higher only in patients with high-grade colonic polyp dysplasia (p<0.05). There were no statistically significant differences in the proportion of incomplete IM between the groups (p<0.05). Conclusion: This study observed increased rates of gastric IM with colonic polyps. An increased risk of gastric IM was associated with higher grades of polyp dysplasia.

Dysphagia represents a difficulty in passage of solid or liquid foods from the oral cavity into the stomach and is considered as an alarm symptom of gastrointestinal system. It often indicates an organic disease and needs to be explained. In this paper, a case of 61-year-old manwith posterior tongue abscess is presented.
A Rare Type of Eosinophilic Gastroenteritis: Eosinophilic Ascites
(2015) Unler, Gulhan Kanat; Ozgur, Gulsum Teke; Erinanc, Ozgur Hilal; Gokturk, Huseyin Savas
Eosinophilic gastrointestinal diseases are a group of inflammatory disorders characterized by signs and symptoms associated with eosinophil infiltration of the gastrointestinal tissues with the absence of any secondary cause of eosinophilia such as parasitic infection, vasculitis and malignancy. Eosinophilic gastrointestinal diseases are rare and eosinophilic ascite is probably the least common and least reported form. We reported a case of 24-year old women presented with eosinophilic ascites and we want to point out a rare cause of ascites that can be managed appropriately.
Reactivation of Resolved Hepatitis B Virus Infection Before The Relapse of Lymphoma : Immunosuppressive Effect of the Lymphoproliferative Disorders ?
(2016) Gokturk, Huseyin Savas; Unler, Gulhan Kanat; Gokturk, Bahar; https://orcid.org/0000-0003-0182-002X; 26852769
Hepatitis B virus (HBV) infection is a heterogeneous disease with distinct phases determined mainly by the interaction between virus replication and host immune response. HBV reactivation can occur spontaneously, developing resistance to antiviral treatment while the patient is undergoing treatment, after cessation of antiviral drugs, or be triggered by immunosuppressive drugs and chemotherapy. HBV reactivation can be severe and sometimes fatal because of liver failure. Here we report a patient with resolved HBV infection who presented with reactivation before being diagnosed with a relapse of non-Hodgkin lymphoma.

Introduction: Cortisol, which is released from the adrenal cortex, is a steroid hormone with vital functions. Its daily release is regulated by the hypothalamic-hypophyseal-adrenal axis. In healthy people, an adequate amount of endogenous corticosteroids is synthesized in the adrenal gland in response to stressful events, but in patients with adrenal insufficiency, there is a steroid synthesis defect that prevents the patient's requirements from being met. It may be challenging to diagnose corticosteroid deficiency in some circumstances, which can lead to catastrophic consequences, including death. Case presentation: In this article, we report a patient who had been using prednisolone 5mg/day for 10 years for rheumatoid arthritis with acute gastroenteritis whose clinical condition deteriorated despite appropriate therapy for 1 week and who was subsequently diagnosed with secondary adrenal insufficiency. Conclusion: On the basis of this case report, we remind clinicians of the necessity of rearranging steroid therapy during the course of an infectious disease in patients previously treated with prolonged steroid therapy.
