Impact of progesterone on the gastrointestinal tract: a comprehensive literature review.

Women are more prone to gastrointestinal symptoms than men. A comprehensive literature search was performed to assess the impact of sex steroid hormone, especially progesterone, on the (healthy and diseased) gastrointestinal tract. Overall, 37 articles were identified. Based on these we conclude that progesterone has a dose-dependent and sex-dependent effect on gastric emptying (especially in mammals), slows down gastrointestinal motility, reduces the gallbladder's response to contractile stimulants, may support gastroesophageal reflux by reducing the esophageal sphincter pressure, may protect from Helicobacter pylori infection gastrointestinal sequelae (especially in mammals) and does not affect inflammatory bowel disease-specific symptoms. However, for several gastrointestinal symptoms and diseases no studies have yet been performed addressing the impact of sex hormone steroids.

Intestinal tuberculosis and inflammatory bowel disease; the usual challenging differential diagnoses: A case report.

Intestinal Tuberculosis (TB) is a very rare presentation of TB, presenting with a nonspecific symptom that mimics Crohn's disease, making diagnosis challenging. We present a case of intestinal tuberculosis in a 37-year-old female who had long-term abdominal pain and diarrhea and showed all the signs of inflammatory bowel disease (IBD) during a thorough clinical, endoscopic, radiologic, and histologic examination. Seven months of right mid- and lower-abdominal discomfort brought a 37-year-old woman to our hospital with pain, diarrhea, bloating, and tiredness worsening after meals. A CT scan of the abdomen highly suggested inflammatory bowel disease. A colonoscopy revealed a patulous ileocecal valve with terminal ileum ulcerations, ileal stenosis, cecum, and valve ulcers, where biopsies findings suggesting also IBD. While planned to start mesalazine; PCR TB testing of biopsy material confirmed tuberculosis. She recovered well following conventional intestinal TB therapy. Intestinal TB is called the great mimicker because its symptoms resemble different illnesses. Misdiagnosis can lead to incorrect treatment, life-threatening complications, and mortality. This paper's radiology, macroscopy, and histopathology highly suggested Crohn's disease, however, intestinal TB was the diagnosis. TB quadrable treatment significantly benefited patients. Consider intestinal TB in this scenario, especially in patients coming from endemic TB areas is highly recommended. The importance of our case report is increasing the awareness that intestinal TB can mimic inflammatory bowel disease and other disorders such as chronic disease and malignancy, for which the treatment is completely different and could lead to fetal outcome; therefore, we should maintain a high level of suspicion when evaluating patients with nonspecific symptoms, particularly in endemic areas of the disease, to obtain a correct diagnosis and appropriate treatment.

Anti-nuclear matrix protein 2 antibody-positive dermatomyositis with gastrointestinal ulcers: A case report.

Gastrointestinal manifestations are a very rare complication of dermatomyositis (DM) and are much less frequent in adult cases than in juvenile cases. Only a few previous papers have reported adult patients who had DM with anti-nuclear matrix protein 2 (anti-NXP2) antibodies and who developed gastrointestinal ulcers. Herein, we report a similar case of a 50-year-old man who had DM with anti-NXP2 antibodies followed by relapsing multiple gastrointestinal ulcers. Even after the administration of prednisolone, his muscle weakness and myalgia deteriorated and gastrointestinal ulcers relapsed. In contrast, intravenous immunoglobulin and azathioprine improved his muscle weakness and gastrointestinal ulcers. Based on the parallel disease activity of the muscular and gastrointestinal symptoms, we considered that his gastrointestinal ulcers were a complication of DM with anti-NXP2 antibodies. We also propose that early intensive immunosuppressive therapy would be required for the muscular and gastrointestinal symptoms in DM with anti-NXP2 antibodies.

Wolfram Syndrome-2, a Cause of Severe Gastrointestinal Bleeding: A Case Series and a Literature Review.

Background: There are very few reports of Wolfram syndrome-2 (WFS2) in the literature, and understanding of involvement of the gastrointestinal (GI) tract in the syndrome is limited. Objectives: This study aims to describe the clinical presentations of a large number of WFS2 patients with specific focus on their GI manifestations. Methods: This is a retrospective case series study. Patients who were homozygous for the CISD2 gene mutation were identified through the genetic department of Al-Makassed hospital. Their medical records were reviewed, and biometric data have been obtained. The data were collected and arranged on a data sheet, and descriptive analysis was done using SPSS. Results: Thirteen patients from 9 families were identified; diabetes mellitus was present in 6 of them, optic atrophy in 5, diabetes insipidus (DI) in 5, and deafness in 2. All of the patients had GI manifestations with abnormal findings on upper endoscopy. Dysmorphic facial features and abnormal findings on brain MRI were present in 3 of our patients. The GI manifestations including GI bleeding and severe ulcerations were the first to appear in 9 of them, while anemia in the remaining 4. Conclusion: This is the largest study to date describing patients with WFS2. This study's evidence shows the prominent presence of GI involvement, and the severe findings on endoscopy, including duodenal, gastric, and esophageal ulcerations and strictures. Unlike in the Jordanian report, some of the patients in our report also have DI.

Wolfram Syndrome Type 2: A Systematic Review of a Not Easily Identifiable Clinical Spectrum.

BACKGROUND: Wolfram syndrome (WS) is a rare autosomal recessive disorder that is characterized by the presence of diabetes mellitus, optic atrophy and hearing loss, all of which are crucial elements for the diagnosis. WS is variably associated with diabetes insipidus, neurological disorders, urinary tract anomalies, endocrine dysfunctions and many other systemic manifestations. Since Wolfram and Wagener first described WS in 1938, new phenotypic/genotypic variants of the syndrome have been observed and the clinical picture has been significantly enriched. To date, two main subtypes of WS that associated with two different mutations are known: WS type 1 (WS1), caused by the mutation of the wolframine gene (WS1; 606201), and WS type 2 (WS2), caused by the mutation of the CISD2 gene (WS2; 604928). METHODS: A systematic review of the literature was describe the phenotypic characteristics of WS2 in order to highlight the key elements that differentiate it from the classic form. CONCLUSION: WS2 is the rarest and most recently identified subtype of WS; its clinical picture is partially overlapping with that of WS1, from which it traditionally differs by the absence of diabetes insipidus and the presence of greater bleeding tendency and peptic ulcers.

Rabbit gastric ulcer models: comparison and evaluation of acetic acid-induced ulcer and mucosectomy-induced ulcer.

In this study, we examined rabbit gastric ulcer models that can serve as more clinically relevant models. Two types of ulcer model were studied: acetic acid-induced ulcers (AAU) and mucosal resection-induced ulcers (MRU). For AAU, rabbit gastric mucosa was exposed by median laparotomy and treated with bottled acetic acid. MRU was examined as a model for endoscopic mucosal resection (EMR). Normal saline was injected into the submucosal layer and the swollen mucosa was resected with scissors. Endoscopic mucosal resection (EMR) is frequently performed for treatment of early gastric cancers. This procedure inevitably leads to ulcers and bleeding. Bleeding control is the major concern in endoscopic mucosectomy, and some endoscopic hemostatic agents are currently under clinical and preclinical studies. MRU was developed as a model for these induced ulcers and the evaluation of the healing process. The clinical relevancy of those models was compared with that of rat models. Progressive healing was observed for 7 days based on histology. Rabbit models demonstrate round, deep ulcers with clear margins and well-defined healing stages that were difficult to define in rat models.

Risk management of risk management: Combining proton pump inhibitors with low-dose aspirin.

Low-dose aspirin is widely used in the primary and secondary prevention of cardiovascular events, but is associated with a range of upper gastrointestinal side effects. In this review, we summarize the rationale for low-dose aspirin therapy, quantify the risk for upper gastrointestinal side effects, identify the risk factors involved, and provide an overview of preventive strategies, thereby focusing on the rationale and clinical utility of combining proton-pump inhibitors with low-dose aspirin.
