Serum Levels of Chemerin, Apelin, and Adiponectin in Relation to Clinical Symptoms, Quality of Life, and Psychological Factors in Irritable Bowel Syndrome.

J Clin Gastroenterol 2020 May/Jun;54(5):e40-e49

Razi Herbal Medicines Research Center, Lorestan University of Medical Sciences.

Background: Adipokines have endocrine roles in metabolism and immunity. Dysregulation of adipokine levels is associated with several diseases with chronic inflammation. We aimed to assess the serum concentrations of chemerin, apelin, and adiponectin in irritable bowel syndrome (IBS). Furthermore, we evaluated the possible association of these adipokines with clinical symptoms, quality of life (QoL), and psychological factors.

Materials And Methods: In this case-control study, 114 male and female IBS patients were recruited from outpatient clinics. Along with the IBS patients, 114 sex and age-matched healthy volunteers were recruited. Patients filled in the questionnaires of the IBS severity scoring system (IBSSS), gastrointestinal (GI) and somatic symptoms, IBS specific QoL (IBS-QoL), and psychological disorders, and went to the lab for blood sampling.

Results: Serum levels of both adiponectin and apelin were significantly (P=0.04, 0.03, respectively) lower, whereas chemerin was significantly (P=0.01) higher in IBS patients. Chemerin was higher in IBS-D compared with both IBS-C and IBS-A, while apelin and adiponectin were not different between subtypes. After adjustments for confounders only, chemerin had a positive association with IB severity scoring system and GI symptoms. Furthermore, chemerin had positive associations, whereas apelin and adiponectin had inverse associations with somatic symptoms and psychological factors. There were no significant associations between adipokines including chemerin, apelin, and adiponectin, and IBS-QoL.

Conclusions: Chemerin had significant associations with both the severity of clinical symptoms and psychological factors in IBS; thus, it could be considered as a potential therapeutic target in these patients; however, further studies are needed.

Colorectal cancer and the genes in the human genome: A meta-analysis.

Genom Data 2016 Dec 1;10:118-126. Epub 2016 Nov 1.

Research Office for the History of Persian Medicine, Lorestan University of Medical Sciences, Khorramabad, Iran.

Colorectal cancer is one of the most common types of inflammation-based cancers and is occurred due to growth and spread of cancer cells in colon and/or rectum. Previously genetic association of cell cycle genes, both proto-oncogenes and the tumor suppressors has been proved. But there were few studies about association of immune related genes such as . Thus we intend to perform a meta-analysis to find the association of different genes of and susceptibility to be affected by colorectal cancer. The overall population of the four studies investigated in our meta-analysis was 953 individuals (470 individuals with colorectal cancer and 483 individuals in control groups). After the analyses, we concluded that colorectal cancer is affected by and also there were no protecting gene. This result shows the inflammatory basis of this cancer. In other words, in contrast to leukemia and blood cancers, colorectal cancers seem to be affected by hyper activity of natural killer-cells (NKs). Whys and therefore of this paradox, is suggested to be investigated further.

Epidemiological and clinical aspects of ulcerative colitis in west of Iran: a cross sectional study.

Springerplus 2016 15;5(1):1588. Epub 2016 Sep 15.

Student Research Committee, Lorestan University of Medical Sciences, Khorramabad, Iran.

Introduction: One of the forms of inflammatory bowel disease (IBD) that causes inflammation and ulcers in colon is ulcerative colitis (UC). This study was aimed to determine the epidemiological and clinical aspects of patients with ulcerative colitis in the west of Iran.

Methods: In this cross sectional study, we evaluated 150 patients with definite diagnosis of UC who referred to a subspecialty gastroenterology clinic in Khorramabad, Iran. The study was performed from May 2014 to August 2015 by using census method. Demographic characteristics as well as patients' clinical profiles were extracted using a checklist. Disease severity was determined by the Truelove and Witt's classification of ulcerative colitis (UC). Data were analyzed using SPSS software, version 17 for windows (IBM Inc., NY, US).

Results: A total of 150 patients with definite diagnosis of UC were analyzed, including 84 (56 %) women and 66 (44 %) men (male/female ratio = 1.27). The mean age of patients was 33.7 ± 12.5 years with an age range of 17-98 years. The age of the majority of patients was 20-29 and most of them (56 %) were women and living in urban areas (70.7 %). The most common site of the involvement in colon was rectosigmoid (66 patients, 44 %). Severity of the disease was mild in 36 patients (24.1 %), moderate and severe in 74 and 40 patients (49.3 and 26.6 %), respectively. The most common clinical manifestation of the patients was dysentery (68 %) and then rectorrhagia (60 %). Only 12 of all patients (7.8 %) mentioned a positive family history of IBD in their first degree kinfolks. Ten patients (6.7 %) had a history of regular smoking and four of them (2.6 %) mentioned a history of appendectomy. Four patients (5.3 %) had a positive history of smoking by their mothers during their pregnancy.

Conclusion: The results of this study demonstrate differences and similarities in demographic and clinical characteristics of UC in this part of Iran in comparison to other parts of the country.

Characteristics of Colorectal Cancer in Khorramabad, Iran during 2013.

Middle East J Dig Dis 2014 Apr;6(2):81-6

Instructor, Faculty of Medicine, Lorestan University of Medical Sciences, Khorramabad, Iran.

BACKGROUND Colorectal cancer is a common, deadly disease with different incidence rates in different parts of the world. The present study aims to investigate the clinical presentations, colonoscopic findings, and family history of colorectal cancer in the city of Khorramabad, Iran. METHODS This cross-sectional study, conducted in 2013, included 112 patients diagnosed with colorectal cancer by colonoscopy with pathological confirmation in addition to 112 individuals matched with patients for age and gender. Controls were chosen from the outpatients admitted to the Skin and Eye Clinics of ShohadaAshayer Hospital in Khorramabad who had no gastrointestinal diseases. A self-generated questionnaire was used to assess family history of smoking and gastrointestinal cancer history in immediate relatives of subjects from both groups. Fisher's exact test and odds ratios (OR) were used to analyze the data. RESULTS Based on the findings of this study, the most common clinical presentation in the patients was abdominal pain (67.9%). The sigmoid colon (40%) was the most common anatomical site of the tumor in men; the rectum (34.6%) and sigmoid colon (34.6%) were the most common sites in women, which was not statistically significant (p=0.21). There were 11 (19.6%) patients and 2 (3.6%) individuals in the control group who reported a history of colorectal cancer in their immediate relatives, which was statistically significant (p=0.008). CONCLUSION In this study, left-sided colon cancer was more common. Subjects with colon cancer had more positive FHx. This indicated that genetic factors, in addition to environmental factors, could increase the incidence of colorectal cancer in a community. A better identification of these factors would result in better control and management of this disease.

Upper Gastrointestinal Bleeding in Khorramabad City in 2011A Single Referral Center Experience.

Middle East J Dig Dis 2013 Oct;5(4):223-9

Researcher, Lorestan University of Medical Sciences, Khorramabad, Iran.

Background: Acute upper gastrointestinal bleeding (UGIB) is a common medical emergencyand is known as one of the main causes of mortality and morbidity. Thisresearch was conducted to study the causes and risk factors for UGIB, in areferral center.

Methods: In this cross sectional study, carried out in a one year period, all patientswith acute UGIB living in Khorramabad city and surrounding area, entered thestudy. A control group with age and sex matched was selected from outpatientvisits and their relatives who had referred to hospital clinics. Data collectingtool was a self-made questionnaire, demographic, clinical manifestations andendoscopic findings. The data was analyzed using chi-square test, Fisher exacttest and Odds ratio estimation.

Results: Sixty-two patients with acute UGIB were studied, 67.7% of them weremales. The mean age of patients was 54.5±12.1. The most common causesof acute UGIB were peptic (42.7%), erosive gastritis (19.8%) and esophagealvarices (19.8%). 29%, and 9.7% of patients, and control group had a history ofregular consumption of Non Steroidal Anti-Inflammatory Drugs ( Odd' s ratio3.8, CI: 1.3-4.8). 35.5% of episodes of acute UGIB were in age more than 60years.

Conclusion: Peptic ulcer disease is the most common cause of acute UGIB in our region.Episodes of acute UGIB were correlated with regular NSAIDs use, but notwith alcohol consumption, smoking, and gender. Identifying people who are atrisk and providing preventive strategies can reduce the rate of this disease andits complications.

Ethnic and geographic differentiation of Helicobacter pylori within Iran.

PLoS One 2010 Mar 22;5(3):e9645. Epub 2010 Mar 22.

Department of Bacteriology and Virology, National Institute of Genetic Engineering and Biotechnology, Tehran, Iran.

The bacterium Helicobacter pylori colonizes the human stomach, with individual infections persisting for decades. The spread of the bacterium has been shown to reflect both ancient and recent human migrations. We have sequenced housekeeping genes from H. pylori isolated from 147 Iranians with well-characterized geographical and ethnic origins sampled throughout Iran and compared them with sequences from strains from other locations. H. pylori from Iran are similar to others isolated from Western Eurasia and can be placed in the previously described HpEurope population. Despite the location of Iran at the crossroads of Eurasia, we found no evidence that the region been a major source of ancestry for strains across the continent. On a smaller scale, we found genetic affinities between the H. pylori isolated from particular Iranian populations and strains from Turks, Uzbeks, Palestinians and Israelis, reflecting documented historical contacts over the past two thousand years.
