Prevalence of Hepatitis B and C Infections and Associated Risk Factors in Pars Cohort Study, Southern Iran

BACKGROUND Hepatitis B and C virus (HBV and HCV) infections rank among the most frequent infectious diseases with a rising worldwide burden. However, their epidemiology and risk factors are understudied in many regions, including Iran. METHODS This study was conducted as part of the Pars Cohort Study (PCS) in Valashahr district, Fars province (2012-2014). Participants received venipuncture for HBsAg and HCV antibody, followed by Polymerase Chain Reaction (PCR) testing. All infected people and their comparison groups completed a risk assessment questionnaire. RESULTS Overall, 9,269 people participated in the study; the majority were women and of Fars ethnicity. Prevalence of HBsAg and HCV antibody was 2.3% (n = 215) and 0.3% (n = 26), from whom 23% (n = 47) and 13% (n = 3) had indications for treatment, respectively. During follow-up, among HBsAg-positive individuals who were not on treatment, 62% tested negative for HBsAg, and in 2% HBV DNA had risen to treatment levels. Risk factors for HBV infection were illiteracy [OR = 3.43, 95% CI = 1.1, 10.3], and Turk ethnicity compared to Fars [OR = 1.58, 95% CI = 1.1, 2.3]. History of blood transfusion [OR = 2.00, 95% CI = 1.1, 3.5] and history of drug use [OR = 2.85, 95% CI = 1.1, 7.4] were associated with HCV infection, after adjustment. CONCLUSION Further epidemiological studies are needed to identify at-risk populations in different regions. Preventive interventions, including educational programs and transfusion safety strategies, are crucial for reducing the hepatitis burden.

Development of Inflammatory Bowel Diseases Registry Software

BACKGROUND With an increase in the prevalence and incidence of inflammatory bowel diseases (IBDs), they have become a global challenge. The IBD registry provides complete and timely data, thereby greatly contributing to the estimation of the burden of these diseases and development of control and prevention programs. We aimed to develop an IBD registry software. METHODS The present applied-developmental study had two main stages: determining user requirements, and developing the IBD registry software. The software was created using a Web-based software development technology called ASP.NET Core 2. The programming language in this framework was #C, and the SQL Server 2017 was employed to create a strong and integrated software databank in the relational form. RESULTS When determining user requirements, the data elements were classified into two main categories of patient information and visits and tests. Moreover, in this stage, registry functions, including case ascertainment, abstracting, follow-up, quality control, and reporting were identified. In the registry software development stage, the object-oriented conceptual model was designed with five use case diagrams and 59 classes. The user interface comprised the following main sections: add patient, find patient, complete source report, report, staff, and drugs. Precise user authentication and authorization were also employed to enhance the security of the developed software. CONCLUSION Development of an IBD registry which can precisely record patients and estimate the incidence, prevalence, and socioeconomic burden of these diseases can assist in planning for the control and prevention of IBD in healthcare systems.

Association between Sleep Quality and Gastroesophageal Reflux in Medical Students

BACKGROUND Due to stressful occupational conditions, irregular dietary and sleep schedules, medical students are at increased risk of developing gastrointestinal disorders, gastroesophageal reflux (GERD) in particular, as well as sleep disturbances. Therefore, for the first time, we aimed to assess the correlation between GERD and sleep disturbances among medical students. METHODS The current cross-sectional study was done on 290 medical students at different study periods in Iran during 2018-2019. Age, sex, stage of studying, residence, and body mass index were gathered. The frequency scale for the symptoms of gastroesophageal reflux (FSSG) was utilized to assess gastrointestinal symptoms among them and the Pittsburgh Sleep Quality Index (PSQI) to assess sleep quality. Eventually, the association of sleep disturbances with demographic factors and gastrointestinal symptoms was evaluated. RESULTS Living in the dormitory (p = 0.048; OR: 1.73; 95%CI: 1.01-2.99) and being overweight (p < 0.001; OR: 3.09; 95%CI: 1.58-6.06) were independently correlated with impaired sleep quality. GERD presented either by heartburn (p < 0.001) or regurgitation (p < 0.001) was associated with a lower quality of life. CONCLUSION GERD was correlated with poor sleep quality among medical students. In addition, residence in dormitory and being overweight were correlated with poor sleep quality.

COVID-19 Outbreak and its Burden on a New Wave of Functional Gastrointestinal Disorders

The current outbreak of COVID-19 infection among humans is strongly impacting global physical and mental health. This outbreak can induce or exacerbate some chronic disorders such as functional gastrointestinal disorders (FGIDs) due to stress, anxiety, depression, insomnia, denial, anger, and fear. The current focus on the physical aspects of COVID-19 infection may distract public attention from the psychosocial consequences of this outbreak. The mental disorders related to this outbreak may develop and extend FGIDs in the long term. FGIDs have a significant impact on daily activities and quality of life and also cause high economic burdens through direct medical costs and loss of productivity. The purpose of this mini-review was to emphasize the critical state of old and new cases of FGIDs during the COVID-19 outbreak. Published English papers about mental health disorders related to the COVID19 outbreak or before the infectious outbreak, stress, and FGIDs were considered and reviewed. We selected articles which were current and had the most relevance to FGIDs, psycho-somatization, and infectious outbreak.

Diagnostic Significance of Serum Fatty Acid Synthase in Patients with Pancreatic Cancer

BACKGROUND Pancreatic cancer is considered as the most deadly tumor among gastrointestinal cancers because of its poor prognosis. The frequently deregulated pathway in the cancer cell is associated with an increased expression of various genes, including the synthesis of fatty acids. We aimed to evaluate the level of serum fatty acid synthase (FASN) as a diagnostic marker for early diagnosis of pancreatic cancer. METHODS Serum FASN levels were measured by ELISA in 92 patients with pancreatic adenocarcinomas and in 92 healthy controls. Logistic regression analysis was used to identify independent predictors of certain diagnostic categories. RESULTS Serum FASN levels were significantly higher in patients with pancreatic cancer than in healthy controls (1.35 [0.98-2.3] ng/mL vs 1.04 [0.19-1.34] ng/mL, p < 0.001) and in smokers compared to non-smokers (1.41 [0.79-2.52] ng/mL vs 1.07 [0.21-1.74] ng/mL, p < 0.001). FASN levels and smoking were associated with increased risk of PC (1.54 [1.1- 2.14] ng/mL, p = 0.011 and 5.69 [2.68-12.09] ng/mL, p < 0.001, respectively). CONCLUSION Elevated serum FASN levels in patients with pancreatic cancer indicate the need for the production of large numbers of lipids for the survival and proliferation of human cancer cells and the diagnostic value of FASN as a new diagnostic biomarker.

Comparing the Effect of Two Low-dose and High-dose Four-drug Regimens of Furazolidone in Eradicating Helicobacter Pylori

BACKGROUND Antibiotic resistance is a major cause of Helicobacter pylori (H. pylori) treatment failures. The increased resistance to clarithromycin and metronidazole has reduced the ability of this therapeutic regimen and prompted researchers to look for other drugs. One of the antibiotics of interest in this regard is furazolidone because of its low drug resistance. The aim of this study is compare two-drug regimens including low-dose and high-dose furazolidone in the treatment of H. pylori. METHODS This study is a clinical trial in which the studied subjects were categorized into two groups. The first group underwent treatment with amoxicillin 1000 mg-BD, furazolidone 100 mg-BD, omeprazole 20 mg-BD, and bismuth subcitrate 240 mg-BD for two weeks (low-dose OFAB). The second group received furazolidone 200 mg-BD (high-dose OFAB). Then eight weeks after completion of the treatment, they were examined in terms of eradication via the UBT test. RESULTS 85 participants completed the study in each group. The response to treatment was 76% and 83% in the low and high-dose groups, respectively, based on intention to treat analysis. Based on per protocol analysis the response to treatment was 78% and 84%, respectively, if excluded patients had completed their protocol and had response to treatment, and 72% and 79%, respectively, if excluded patients had completed their protocol and did not have response to treatment (p = 0.298). In the low-dose and high-dose groups, 16.5% and 24.7% of the participants suffered the complications of treatment with furazolidone (p = 0.18), respectively. Three patients in the high-dose group and one in the low-dose group did not complete the treatment because of the medication’s bad taste (p = 0.03). CONCLUSION Low doses of furazolidone had a comparable therapeutic effect compared with high doses, but patients experienced significantly lower levels of bad taste, which was a major cause of reluctance to continue treatment. Therefore, we think four-drug low-dose furazolidone treatment is a good choice in eradicating H. pylori.

Blue Rubber Bleb Nevus Syndrome because of 12 Years of Iron Deficiency Anemia in a Patient by Double Balloon Enteroscopy; A Case Report and Review of Literature

Blue rubber bleb nevus syndrome (BRBNS) is a rare disorder comprised of venous malformation mostly involving the skin and gastrointestinal (GI) tract but can also involve other visceral organs. The most predominant site of GI tract involvement is the small bowel. In patients with GI lesions, treatment depends on the severity of bleeding, and extent of involvement. Conservative therapy with iron supplementation and blood transfusion is appropriate in cases with mild bleeding but in severe cases endoscopic and surgical interventions would be beneficial. Also, medical therapy with sirolimus significantly reduces bleeding. A 20-year-old woman was referred to our hospital after transfusion of six units of packed cell because of several episodes of lower GI bleeding within the past three months in the form of melena and a single episode of hematochezia. Her last hemoglobin level before admission was 10mg/dl. She underwent various unsuccessful investigations since she was eight years old to find the origin of refractory iron deficiency anemia. In upper endoscopy, five bleeding polypoid lesions were discovered in the jejunum. Lesions were excised by snare polypectomy. Over a six-month follow-up period, no signs of lower GI bleeding were noted and the patient had a normal hemoglobin level.

Different Clinical Features of Celiac Disease in Children, Adolescents, and Adults; a Cross-sectional Study

BACKGROUND Celiac disease is a common disorder but there are few studies comparing the clinical features of the disease in adults, adolescents and children. METHODS Demographic and clinical characteristics of all patients with celiac disease referred to the Celiac Clinic were evaluated and compared in different age groups. RESULTS Of 3416 participants, 473 patients were included. 302 (63.8%) were women and 171 (36.2%) were men. Overall, 325 (68.7%) and 411 (86.9%) patients had gastrointestinal (GI) and non-GI manifestations, respectively. The most common symptom in adults was psychiatric problems (66.5%), while abdominal discomfort was the most common symptom in adolescents (45.2%) and children (53.8%). According to age groups, GI manifestations were seen in 79 (66.4%), 119 (59.8%), and 127 (81.9%) children, adolescents, and adults, respectively. Adults had significantly more GI manifestations than the other groups (PR 1.167; 95% CI: 1.094- 1.244; p < 0.001). Non-GI manifestations were seen in 90 (75.6%), 174 (87.4%), and 147 (94.8%) children, adolescents, and adults, respectively. Adults had significantly more non-GI manifestations than the other groups (PR 1.112; 95% CI: 1.060-1.168; p < 0.001). CONCLUSION Our study showed that there were significant differences in the clinical features of celiac disease between the different age groups. Considering these results may help plan for future studies.

Extrapulmonary Sarcoidosis Manifested as Cirrhosis with Portal Hypertension

Hepatic involvement has been reported in 20-30% of patients with systemic sarcoidosis. However, isolated liver involvement is rare. We report a case of cirrhosis with portal hypertension, diagnosed as hepatic sarcoidosis based on high angiotensin-converting enzyme level and presence of multiple non-caseating granulomas in liver histopathology. She improved clinically after treatment with steroid and ursodeoxycholic acid.
