Abstract
Ulcerative colitis is one of the two main subtypes of inflammatory bowel disease, along with Crohn's disease. Understanding the clinical and endoscopic features of ulcerative colitis is critical in achieving a timely diagnosis. An initial evaluation includes assessing clinical symptoms, inflammatory markers, endoscopic findings, and determination of the presence or absence of extraintestinal manifestations. Initial disease management should consider disease severity at the time of diagnosis as well as prognostication, or the determination of risk factors present with a high likelihood of severe disease in the future. Once appropriate therapy has been initiated, ongoing monitoring is crucial, which may include repeated clinical assessments over time, measuring noninvasive markers of inflammation, and endoscopic and histologic reevaluation. An important aspect of disease monitoring in ulcerative colitis is dysplasia surveillance; there are many patient-specific risk factors which influence surveillance strategies. Utilizing appropriate surveillance techniques is necessary for early detection of dysplasia and colorectal neoplasia.

Difficulties in the differential diagnosis of intestinal tuberculosis and Crohn‘s disease. ACTA BIOMEDICA SCIENTIFICA 2021.

Abstract
The differential diagnosis of intestinal tuberculosis and Crohn’s disease is a difficult task for most specialists due to their high similarity in clinical manifestations, instrumental diagnosis and histological pattern.The aim: to consider the clinical and diagnostic features of intestinal tuberculosis and Crohn’s disease, to show the role of various methods of their diagnosis (CT of the abdominal cavity, CT-enterography, colonoscopy with biopsy).A clinical example shows a case illustrating the difficulties of diagnosing intestinal tuberculosis, initially diagnosed as Crohn’s disease. The features of the course, complex diagnosis and treatment of intestinal tuberculosis and its complications during immunosuppression are demonstrated. At the first stage of treatment, the patient’s data related to CT of the chest organs, colonoscopy and histological examination of biopsy samples were incorrectly interpreted. As a result, a wrong diagnosis of Crohn’s disease was made, and immunosuppressive therapy was prescribed that provoked a generalization of the existing tuberculosis process. Subsequently, repeated surgical interventions were performed for complications of intestinal tuberculosis – perforation of tuberculous ulcers, peritonitis. Based on the analysis of the literature data and our own observation, it is shown that granulomatous inflammation in the study of intestinal biopsies doesn’t always allow us to make a clear diagnosis, first of all, there are intestinal tuberculosis and Crohn’s disease in the differential diagnostic series. The use of histobacterioscopy according to Ziehl – Neelsen, the study of fecal matter by luminescent microscopy, as well as molecular genetic methods for detecting DNA MTB allow us to verify the diagnosis. If Crohn’s disease is misdiagnosed as intestinal tuberculosis, then the prescribed anti-tuberculosis therapy can cause harm and lead to a delay in the underlying disease treatment. The reverse misdiagnosis is potentially more dangerous: if tuberculosis is misdiagnosed as Crohn’s disease, then the appointment of immunosuppressive therapy can lead to the generalization of tuberculosis and the development of fatal complications.

Abstract
BACKGROUND Inflammatory bowel diseases are gaining more interest in the past few years. Ulcerative colitis (UC) is a chronic disease that requires accurate follow-up for a good treatment plan. Colonoscopy alone cannot be efficient to detect disease extent and has a high risk of perforation in acute severe UC and toxic megacolon. Computed tomographic enterocolonography (CTE) is widely used now to detect intramural, extra-intestinal involvement and intestinal complications. Hence, this study aimed to evaluate CTE in the assessment of the degree of activity of UC. PATIENTS AND METHODS This cross-sectional study was carried on 50 UC patients, divided into 36 males and 14 females presented at the Gastroenterology Unit, Alexandria Main University, Faculty of Medicine. Assessment of UC activity was done to all patients on three levels; the ulcerative colitis disease activity index for the clinical level, ulcerative colitis endoscopic index of severity by endoscopy and pathologically by degree of neutrophilic invasion, crypt abscess or cryptitis, presence of oedema and mucosal surface ulceration, then CTE was done and the findings were compared with the histopathological findings. Bowel wall thickening in CTE was divided into: normal (<3 mm, score 0), mild (3-6 mm, score 1), moderate (6-9 mm, score 2) and severe (>9 mm, score 3). Mesenteric hyperaemia, mucosal hyper enhancement and enlarged pericolic lymph nodes were recorded. RESULTS CTE findings in the form of bowel wall thickening and hyper enhancement were found in 74% of active cases and were correlated with all histopathological findings investigated in this study with high statistical significance except in chronic stages, whereas lymph node enlargement and mesenteric hyperaemia did not show statistical significance with disease activity. CONCLUSION CTE is a good tool for diagnosing disease activity in UC.

Abstract
Acute severe ulcerative colitis [ASUC] remains a common medical emergency, with 25% of patients with ulcerative colitis experiencing at least one event in their disease course. Despite advances in medical therapy, ASUC continues to be associated with considerable morbidity and mortality, with up to 30% of patients requiring colectomy during initial admission. Our aim was to review the current controversies and recent progress in risk stratification, prediction of outcome, and personalisation of care in ASUC. We re-assess the use of Truelove and Witts' criteria, serum biomarkers, and the use of composite clinical indices in current clinical practice. We explore the potential for endoscopic prediction using defined validated indices for accurate and early prognostication, and the need to define outcome. We also consider the impact of the current COVID-19 pandemic. Finally, we discuss the current research agenda, including the application of new and emerging biomarkers coupled with multi-omics and the implications in management and optimisation of outcome. Research priorities for the prediction of outcome in acute severe colitis include the following. 1. Development of an accurate admission score to guide early medical rescue therapy or colectomy. 2. Utility of point-of-care faecal calprotectin, with determination of optimal cut-off values. 3. Role of serum and faecal infliximab levels to both predict outcome and guide accelerated infliximab dosing. 4. Role of novel biomarkers, including serum calprotectin, in predicting response to corticosteroids or rescue therapy. 5. Specific predictors of response to ciclosporin and infliximab to allow rationalisation of drug use. 6. Utility of validated endoscopic scores. 7. Utility of radiological assessment beyond use of plain abdominal X-ray. 8. The use of multiomics and machine learning to predict risk of Acute Severe Colitis in patients with Ulcerative Colitis.

Abstract
The majority of liver grafts exhibit abnormal histological findings late after transplantation, even when liver enzymes are normal. Such subclinical graft injuries were associated with rejection and fibrosis progression in recent studies. The identification of non-invasive biomarkers for subclinical graft injury might help to individualize immunosuppression. Therefore, graft injury was assessed in 133 liver biopsies with normal/near normal liver enzymes from a prospective liver biopsy program. Cytokeratin-18 cell death marker (M65) and donor specific anti-HLA antibodies (DSA) were measured as non-invasive markers in paired plasma samples in addition to routine parameters. M65 was associated with subclinical graft injury but this association was too weak for reasonable clinical application. DSA positivity was associated with more graft inflammation (OR = 5.4) and more fibrosis (OR = 4.2). Absence of DSA excluded fibrosis in 87–89%, while presence of DSA excluded histological criteria for immunosuppression minimization attempts in 92–97%. While CK18 cell death marker had no diagnostic value for the detection of subclinical liver graft injury, DSA testing can help to preselect patients for immunosuppression reduction in case of DSA negativity, while DSA positivity should prompt elastography or liver biopsy for the assessment of subclinical graft injury.

[DOI: 10.13105/wjma.v8.i2.163] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/29/2019] [Revised: 02/22/2020] [Accepted: 03/26/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Over the last 40 years, with accumulating evidence demonstrating a significant increase in the incidence of ulcerative colitis (UC) in China, the number of studies on UC has been rapidly increasing. But it still lacks a comprehensive meta-analysis of publications regarding UC for the last four decades in China. Thus, a bibliometric analysis of UC is warranted to investigate the trend and distribution of the publications on UC in China in recent years. And it is supposed that the number of the papers related to UC increased by year.
AIM To investigate the current status of research output from Chinese studies related to UC during the period of 1978 to 2017, with special attention paid to the distribution of publication dates, journals, regions, and research organizations.
METHODS Publications on UC were searched in the Chinese periodical database SinoMed from January 1978 to December 2017. The search term used for retrieval was “ulcerative colitis”. The language of the publications was restricted to English or Chinese. The studies have to be performed in China. Then, a bibliometric analysis was performed on the distribution of publication dates, journals, regions, and research organizations with EndNote, Excel, MySQL, and GraphPad Prism.
RESULTS A total of 16257 papers matched the search criteria, which included 7561 papers published in core journals, 4641 evidence-based articles, and 4177 publications of randomized controlled trials. These papers were mainly published in Chinese Journal of Coloproctology, World Chinese Journal of Digestology, Chinese Journal of Digestion, Chinese Journal of Integrated Traditional and Western Medicine on Digestion, and Modern Journal of Integrated Traditional Chinese and Western Medicine. In particular, the majority of these organizations were located in Jiangsu, Henan, Shandong, and Guangdong Provinces which are rich areas or have the largest population per province. Most of these studies were conducted by academic institutions.
CONCLUSION Over the past four decades, the output of research into UC in China has increased significantly, with academic institutions playing a central role in the academic field, but the number and quality of these researches vary substantially among different regions.

Abstract
OBJECTIVE To compare the performances, tolerability and acceptability of mannitol and polyethylene glycol (PEG) as oral contrast agents in patients undergoing computed tomography enterography (CTE). METHODS Patients aged 18-75 years indicated for CTE were randomized to receive either mannitol or PEG as contrast agents. The coronal reconstructed images of each abdominal quadrant were assessed for maximum distention, proportion of distended bowel loops, presence of inhomogeneous contents and visibility of the small bowel wall. Overall subjective imaging quality assessment and patients' tolerability and acceptability were recorded. RESULTS Seventy patients were enrolled and randomized into two groups. In the per-protocol analysis, no significant differences in imaging quality was found in bowel distention maximum diameter, wall visibility and intestinal homogeneity (all P > 0.05). The mean nausea score was lower in the mannitol group (0 [0-0] vs 1.0 [0-3.0], P < 0.001). Mannitol was superior to PEG in taste (9.0 [8.0-10.0] vs 7.0 [5.0-8.0], P < 0.001), patients' willingness to reuse the drug (9.0 [8.0-10.0] vs 8.0 [7.0-9.0], P = 0.036), satisfaction (9.0 [8.0-10.0] vs 8.0 [7.0-9.0], P = 0.022) and ease of completion (9.0 [8.0-9.3] vs 8.0 [6.5-9.0], P = 0.030). CONCLUSIONS Both mannitol and PEG provided good bowel distention and visualization of the bowel wall. However, mannitol was significantly superior to PEG in patients' tolerability and acceptability.

Abstract
In ulcerative colitis, an inflammatory bowel disease of unknown cause, diagnosis of the degree and location of colitis at an early stage is required to control the symptoms. Changes in redox status, including the production of reactive oxygen and nitrogen species (RONS), have been associated with ulcerative colitis in humans and dextran sodium sulfate (DSS)-induced colitis in rodents. In this study, the in vivo redox status of colons of DSS-induced colitis mice were monitored by Overhauser-enhanced magnetic resonance imaging (OMRI), and the relationship between redox status and colitis development was investigated. Colitis was induced by administering 5% DSS in drinking water to male Slc:ICR mice, which are a strain classified as closed colony outbred mice (5-week-old, 25-30 g). On the 3rd day of the DSS challenge, when no symptoms of colitis were displayed, the contrast decays of 15N-CmP and 14N-CxP tended to show enhancement in the whole colon and were not altered by DMSO. On the 5th day of the DSS challenge, with histological damage of the rectum being displayed, the contrast decay of 15N-CmP was significantly enhanced not only in the rectum, but also in the proximal colon, and this was suppressed by DMSO. On the 7th day of the DSS challenge, with the mice displaying severe colitis symptoms, the image contrasts of 15N-labeled 3-carbamoyl-2,2,5,5-tetramethylpyrrolidine-1-oxyl (15N-CmP) and 14N-labeled 3-carboxyl-2,2,5,5-tetramethylpyrrolidine-1-oxyl (14N-CxP) showed much faster decay than those of healthy mice, while the increased decays of both probes were restored by the membrane-permeable reactive oxygen species (ROS) scavenger dimethyl sulfoxide (DMSO). Image differencing between the decay rate images of 15N-CmP and 14N-CxP showed the DSS-induced redox imbalance spreading over the whole colon, and a histogram of the difference image showed a smaller peak and broader distribution with the DSS treatment. These data indicate that ROS are produced intracellularly in the distal and proximal colon in the initiation stage of DSS-induced colitis, and that ROS are produced intracellularly and extracellularly in the advanced stage of DSS-induced colitis.
