Angiogenesis is an important component of pathogenesis of inflammatory bowel disease (IBD). Chronic inflammation and angiogenesis are two closely related processes. Chronic intestinal inflammation is dependent on angiogenesis and this angiogenesis is modulated by immune system in IBD. Angiogenesis is a very complex process which includes multiple cell types, growth factors, cytokines, adhesion molecules, and signal transduction. Lymphangiogenesis is a new research area in the pathogenesis of IBD. While angiogenesis supports inflammation via leukocyte migration, carrying oxygen and nutrients, on the other hand, it has a major role in wound healing. Angiogenic molecules look like perfect targets for the treatment of IBD, but they have risk for serious side effects because of their nature.

Bismuth salts exert their activity within the upper gastrointestinal tract through action of luminal bismuth. Bismuth exerts direct bactericidal effect on Helicobacter pylori by different ways: forms complexes in the bacterial wall and periplasmic space, inhibits different enzymes, ATP synthesis, and adherence of the bacteria to the gastric mucosa. Bismuth also helps ulcer healing by acting as a barrier to the aggressive factors and increasing mucosal protective factors such as prostaglandin, epidermal growth factor, and bicarbonate secretion. To date, no resistance to bismuth has been reported. Also synergism between bismuth salts and antibiotics was present. It was shown that metronidazole and clarithromycin resistant H. pylori strains become susceptible if they are administered together with bismuth. Bismuth-containing quadruple therapy was recommended both by the Second Asia-Pacific Consensus Guidelines and by the Maastricht IV/Florence Consensus Report as an alternative first choice regimen to standard triple therapy, in areas with low clarithromycin resistance, and it is recommended as the first-line therapeutic option in areas with a high prevalence of clarithromycin resistance. Greater than 90% eradication success can be obtained by bismuth-containing quadruple therapy. Choosing bismuth as an indispensable part of first-line therapy is logical as both metronidazole and clarithromycin resistances can be overcome by adding bismuth to the regimen.

This study demonstrated markedly higher PTX3 levels in NAFLD patients compared with controls, and in biopsy proven NASH patients compared with non-NASH ones. Thus, in this cohort we showed that plasma PTX3 may be a promising biomarker for the presence of NASH.

ST2, a specific ligand of interleukin 33, was described as a biomarker protein of inflammatory processes and overexpression of ST2 in ulcerative colitis (UC) was shown previously. We aimed to investigate the potential relationship of serum ST2 levels with the clinical, endoscopic and histopathological activity scores in UC and Crohn's disease (CD). Serum ST2 levels were determined in 143 patients with inflammatory bowel disease (IBD) (83 UC and 60 CD), in 50 healthy controls (HC), and in 32 patients with irritable bowel syndrome (IBS). Serum ST2 levels were elevated in IBD (56.8 (41.9-87.2) pg/mL) compared to HC and IBS (30.7 (20.2-54.3), p<0.001 and 39.9 (25.9-68.7) pg/mL, p=0.002, respectively). No significant difference was found between UC (54.2 (41.3-93.0) pg/mL) and CD (63.8 (42.7-88.4) pg/mL) and between IBS and HC. Serum ST2 levels were significantly increased in active UC compared to inactive UC (72.5 (44.1-99.5) vs 40.0 (34.7-51.6) pg/mL, p<0.001) and in active CD in comparison with inactive CD (63.8 (42.7-88.4) vs 48.4 (29.6-56.9) pg/mL, p=0.036). Patients with CD showing fistulizing behavior had significantly higher ST2 levels compared to patients with inflammatory and stricturing CD (p<0.001). Clinical activity scores of patients with UC and CD were correlated with serum ST2 levels (r=0.692, p<0.001 and r=0.242, p=0.043, respectively). Serum ST2 levels showed stepwise increases with the increasing histopathological scores of patients with UC and CD (p<0.001 for both). The present study highlights significant associations between ST2 and IBD presence and activity and demonstrates elevated serum ST2 levels in patients with active CD as a novel finding.

Our findings suggest that HJV levels are low in NAFLD and even lower in iron overloaded NAFLD, while hepcidin levels are higher in NAFLD with iron overload. The gradually decreased HJV and increased hepcidin concentrations in our patients most likely reflect the physiological response to iron accumulation in the liver.

An increase in the prevalence of colorectal polyps and cancer is reported in patients with acromegaly. This trial is designed to determine whether there is an increase in the prevalence of colorectal polyps/cancer in Turkish acromegaly patients. Sixty-six patients, who were under follow-up with the diagnosis of acromegaly and underwent total colonoscopic examination, were enrolled in the study. Sixty-five age- and gender-matched patients with nonspecific complaints were selected as control. The mean age of acromegalic patients was 51.5 ± 12.8 years of whom 27 (40.9%) were females. In 20 (30.3%) of the patients with acromegaly a total of 65 colorectal polyps were detected. Forty-seven (72.3%) of the polyps were detected at the rectosigmoid region. In 8 (12.3%) of the 65 control patients a total of 17 polyps were found. There was a statistically significant difference between the groups (P = 0.018). At the logistic regression analysis we found that the risk for colon polyps increased 3.2-fold in the presence of acromegaly, irrespective of age and gender (OR: 3.191, 95% CI: 1.25–8.13). In conclusion, patients who were followed up with the diagnosis of acromegaly should be taken to the colonoscopic surveillance program and all polyps detected should be excised in order to protect them from colorectal cancer.

Self-measurement of blood pressure (BP) at home is more common than 10 years ago and encouraged by current guidelines to increase patient adherence to treatment and reach the goal of target BP. The aims of this study are to evaluate the accuracy of home sphygmomanometers and to investigate behavior/knowledge of the sphygmomanometer owners. A campaign was planned to determine the accuracy of home sphygmomanometers in 2006. Seven hundred and twenty-three home sphygmomanometers were brought by individuals to the University Hospital Hypertension Clinic within 1 year and 693 (96%) of the devices were in adequate working condition and suitable for analysis. Four hundred and thirty-nine (63%) of the sphygmomanometers were automatic. Four hundred and eleven (59.3%) of the 693 sphygmomanometer were inaccurate. About 80% (256/320) of the wrist devices were inaccurate. Most studies evaluating the accuracy of sphygmomanometers are conducted in hospital or primary care settings; studies investigating home sphygmomanometers are rare. High frequency of inaccurate home devices is a major public health problem. In conclusion, inaccurate devices have been used in home BP measurements frequently and frequency of device-related errors can be decreased by awareness and training of the patients. Physicians and healthcare providers should advise the patients to check the accuracy of their home sphygmomanometers regularly.

Aim: In our study, we investigated the efficiency of the prognostic nutritional index (PNI) score and the CRP, age, platelet count, albumin level (CAPA) score predicting mortality and intensive care unit (ICU) admission in COVID-19 disease. Materials & methods: PNI and CAPA score of patients confirmed with COVID-19 calculated by using the complete blood count and biochemical parameters at admission to the hospital, in predicting the COVID-19-associated mortality and ICU admission were analyzed. Results: PNI and CAPA scores in predicting mortality were detected as AUC: 0.67 (p < 0.001), AUC: 0.71 (p < 0.001), respectively. For predicting ICU admission AUC was 0.66 (p < 0.001), AUC was 0.77 (p < 0.001), respectively. Conclusion: PNI and CAPA scores are effective scores in COVID-19, with CAPA score being better in predicting mortality and ICU admission.
