The Association of Short Segment Barrett's Esophagus With Intestinal Metaplasia in Stomach
(2003) Tuncer, I.; Ugraş, S.; Uygan, I.; Türkdoǧan, K.; Kösem, M.
Background/aims: The aims of this study were to investigate the presence of short segment Barrett's esophagus in people found to have tongue-like columnar mucosal protrusions in the distal esophagus and to determine the relationship between short segment Barrert's esophagus and Helicobacter pylori, gastritis and intestinal metaplasia observed in other parts of the stomach. Methods: The study included 50 patients (32 male, 18 female). Two biopsy specimens were taken from the antrum, at least 2 cm away from the pylorus, from the incisura angularis, corpus and cardia and four biopsy specimens were taken from tongue-like columnar protrusions (<3 cm long) above the gastroesophageal junction. Tissue samples were stained with hematoxyline-eosine, HID-Alcian blue pH 2.5 and modified Giemsa. Results: Of the 50 subjects who were found to have tongue-like columnar protrusions above the gastroesophageal junction, short segment Barrett's esophagus was detected in nine (18%). Whereas all short segment Barretti's esophagus cases were associated with chronic gastritis, Helicobacter pylori was found to be positive in five (55.5%) of them and there was intestinal metaplasia in other parts of the stomach (antrum in two patients, incisura angularis in three, antrum and cardia in one) in six (66.6%) cases. In 41 patients without short segment Barrett's esophagus 33 (80%) had chronic gastritis, 27 (66%) had Helicobacter pylori infection and eight had intestinal metaplasia in different locations (there in antrum, four in incisura angularis, one in the antrum and cardia) of the stomach. Conclusions: An association between short segment Barrett's esophagus and intestinal metaplasia was found in different parts of the stomach. The link between intestinal metaplasia in the stomach and these metaplastic changes in the tubular esophagus requires evalation in larger and more comprehensive studies.
Clinical and Epidemiological Characteristics of Hepatocellular Carcinoma Cases in East and Southeastern Region of Turkey: a Multicenter Retrospective Study
(Turkiye Klinikleri, 2013) Yalçin, K.; Yakut, M.; Deǧertekin, H.; Türkdoǧan, K.; Harputluoǧlu, M.; Bahçecioǧlu, I.H.; Yilmaz, N.
Objective: In this multicenter retrospective study, we aimed to investigate the epidemiological and clinical characteristics of patients with hepatocellular cancer (HCC) in the Eastern and Southeastern Anatolian regions of Turkey. Material and Methods: This study included 218 patients from 7 centers-Dicle University (n=96), Yüzüncü Yi{dotless}l University (n=30), İnönü University (n=28), Fi{dotless}rat University (n=24), Gaziantep University (n=20), Atatürk University (n=19), and Harran University (n=1) hospitals. Information about patients was obtained through pre-prepared forms. Diagnosis of HCC was made histologically or with a combination of clinical, radiological, and laboratory findings. Results: The mean age of the patients was 57.67±12.03 with a male-to-female ratio of 5.8:1. Etiologically, 45% of the study group had HBV infection alone, 29% had HDV co-infection, 15% had HCV infection and 10% were idiopathic cases with unknown etiology. Cirrhotic background was present in 94% of the patients and 89% of cases had an advanced stage disease according to the Okuda classification. Alpha-fetoprotein levels were over 300 ng/ml in 81% of the patients. Conclusion: Hepatitis B virus infection followed by hepatitis delta virus infections appeared to be the leading etiological factors for HCC cases in our region. HBsAg carriage continues to be an important risk factor for HCC in Turkey. The fact that most of the HCC cases are in the late stages of disease, makes it necessary to use effective diagnosis and treatment methods with efficient screening and monitoring programs in our country. © 2013 by Türkiye Klinikleri.
The Comparative Effects of Pentoxifylline and Ursodeoxycholic Acid on Il-1β, Il-6, Il-8 and Tnf-Α Levels in Nonalcoholic Fatty Liver
(2003) Tuncer, I.; Uygan, I.; Dülger, H.; Türkdoǧan, K.; Şekeroǧlu, R.; Kösem, M.
Objective: To investigate the comparative effects of the pentoxifylline (PTX) and ursodeoxycholic acid (UDCA) on IL-1β, IL-6, IL-8 and TNF-α in non-alcoholic fatty liver (NAFL) cases. Method: Twenty-eight cases diagnosed to have NAFL were included in our study. The cases were divided into 3 groups. 20 mg/kg/day PTX was given to the subjects in group A (6 male, 4 female), 15 mg/kg/day UDCA was given to the subjects in group B (5 males, 5 females) for 6 months. The cases in group C (5 male, 3 female) were followed as control group. The biochemical values and cytokine levels of the cases were evaluated before and at the end of the sixth month of the treatment. Results: When compared with the serum cytokine levels before and after the treatment, IL-8 and TNF-α levels were found to be significantly decreased both in group A and group B (p< 0.05), whereas there was no statistically significant change in IL-1β and IL-6 levels (p > 0.05). Conclusion: While PTX and UDCA significantly decreased the serum IL-8 and TNF-α levels in NAFL, their effects on IL-1β and IL-6 were not significant.
