INTRODUCTION: Invasive and non-invasive tests can be used to evaluate the activity of inflammatory bowel diseases. OBJECTIVE: The aim of the present study was to investigate the role of fecal calprotectin in evaluating inflammatory bowel disease activity and the correlation of fecal calprotectin with the erythrocyte sedimentation rate and C reactive protein values in inflammatory bowel disease. METHOD: Sixty-five patients affected with inflammatory bowel disease were enrolled. Twenty outpatients diagnosed with inflammatory bowel disease comprised the control group. RESULTS: In the present study, all patients in the control group had an fecal calprotectin value lower than the cut-off point (50 mg/kg). CONCLUSION: In conclusion, fecal calprotectin was found to be strongly associated with colorectal inflammation indicating organic disease. Fecal calprotectin is a simple and non-invasive method for assessing excretion of macrophages into the gut lumen. Fecal calprotectin values can be used to evaluate the response to treatment, to screen asymptomatic patients, and to predict inflammatory bowel disease relapses

The aim of the study was to compare 3 stool antigen tests for diagnosis of Helicobacter pylori infection in adult patients with dyspeptic complaints before eradication therapy. We compared 2 enzyme immunoassays (EIAs: Premier Platinum Helicobacter pylori Stool Antigen [HpSA] Plus and Helicobacter pylori Antigen [Hp Ag]) and one immunochromatographic assay (H. pylori fecal antigen test-lateral-flow chromatography) in detecting H. pylori. All the investigated stool antigen tests were made of monoclonal antibodies. We evaluated 168 adult patients with H. pylori infection by using 2 criterion standard methods (histological and rapid urease tests) together. The sensitivity and specificity were 90% and 91%, respectively, for the Premier Platinum HpSA Plus, 77% and 91%, respectively, for the Hp Ag, and 81% and 92%, respectively, for the H. pylori fecal antigen test, respectively. The best agreement between the criterion standard tests and the stool antigen tests used in the study was with the Premier Platinum HpSA Plus. Immunochromatographic assay-based stool antigen test (H. pylori fecal antigen test) was found to be more sensitive than the EIA-based test (Hp Ag). One of the 2 important conclusions obtained from the study was that the Premier Platinum HpSA Plus was found to be the most accurate test for the diagnosis of H. pylori infection in adult dyspeptic patients before eradication therapy, and the other was that monoclonal and high-quality, reliable immunochromatographic assay tests are a good option especially for small hospital laboratories that do not have appropriate equipment for performing the EIA and working on few samples.

respectively). Atrophy was found in 27 (5.5%) of all cases (in 10 Helicobacter pylori (-) patients and in 17 Helicobacter pylori (+) patients), but no significant relation was found with increasing Helicobacter pylori intensity (p>0.05). There was no significant difference between corpus alone or antrum alone Helicobacter pylori (+) and both corpus/antrum (+) patients in regards to the presence of activity, inflammation, intestinal metaplasia, and atrophy (p>0.05). Conclusions: Determination of the degree of morphological changes accompanying Helicobacter pylori infection in dyspepsia is important in the follow-up and treatment of patients. As activity, inflammation and intestinal metaplasia increase with increasing Helicobacter pylori intensity in dyspepsia patients, Helicobacter pylori eradication treatment can be recommended in these patients.

Background/Aims: The prevalence of gallbladder stone (GBS) is shown to be increased in some studies in patients with chronic kidney disease (CKD). Nevertheless, some other studies did not confirm these findings. The controversial results about the prevalence of GBS in hemodialysis (HD) patients demand new studies to search GBS prevalence and associating risk factors in HD patients. In the present study, we aimed to investigate GBS prevalence and risk factors in our HD patients. Materials and Methods: A total of 104 HD and 149 control patients were involved. Complete physical examinations, including measurements of dry body weight and height, were done. Abdominal ultrasonography was conducted by the same experienced radiologist. Blood samples were drawn via venipuncture from the study participants after they had fasted overnight just before a midweek hemodialysis session for laboratory examinations. Results: The prevalence of GBS in HD patients was 34.6 % (36/104), and that was significantly higher than that of control group 12.9% (17/149; p=0.0001). In all study participants (HD patients and control group), patients with GBS were older than patients with no GBS (63.2±14.2 vs 53.7±16.7; p=0.0001). However, in HD patients, mean age was similar in patients with GBS and no GBS (64.3±13.8 vs 60.1±16.6; p>0.05). Patients with GBS had a higher prevalence of units of blood transfusions than patients with no GBS in hemodialysis patients (2.0±2.9 vs 0.9±1.3; p=0.047) Conclusion: The present study showed an increased prevalence of GBS in HD patients compared to healthy controls. The number of blood transfusions and autonomic neuropathy may be responsible for the increased prevalence of GBS in HD patients.

Aim. Colonic polyps and thyroid nodules are common diseases and their frequency increases with age. In the literature, there is no study investigating the coexistence of colonic polyps and thyroid nodules. Therefore, this study was designed to investigate thyroid nodule prevalence in patients with colonic polyps. Material and Methods. Sixty-six patients with colonic polyps and 146 patients without colonic polyps enrolled into the study. Age and sex matched control group was composed from patients without colonic polyps. Colonoscopic examinations, thyroid ultrasonographies were performed in all patients, and TSH were measured. Results. Male/female ratio in polyp and control groups were 40/26 versus 68/78, respectively (P = 0.058). Mean ages were similar in both groups (53.3 ± 11.4 versus, 51.8 ± 11.4, P = 0.373). Thyroid nodule was detected in 44 (66.7%) patients with polyps and in 61 (41.8%) controls (P = 0.001). Patients with adenomatous polyps had 5 or more thyroid nodules compared to patients with hyperplastic polyps (P = 0.03). Thyroid nodules were more prevalent among patients aged 50 or older compared to 50 years or less (P = 0.023). Conclusion. Thyroid nodules were detected more common in patients with colonic polyps. Further studies are needed to clarify this coexistence.

Acute pancreatitis is a frequently encountered disorder in patients presenting to emergency units. Biliary system disorders, alcohol consumption, infections, and drugs are among the causes of acute pancreatitis. However, it is sometimes difficult to determine the etiology of this disorder, particularly if the patient does not wish to disclose his consumption of cannabis, the use of which is illegal.
