Epidemiological trends in acute pancreatitis: A retrospective cohort in a tertiary center over a seven year period

BACKGROUND

Acute pancreatitis (AP) remains a major cause of hospitalization and mortality with important health-related costs worldwide. Using an electronic database of a large tertiary center, we estimated the incidence, etiology, severity and costs of hospitalized AP cases in southern Romania.

AIM

To estimate the incidence, cost and tobacco usage of hospitalized AP cases in southern Romania and to update and upgrade the knowledge we have on the etiology, severity (in regard to Revised Atlanta Classification), outcome, morphology and local complications of AP.

METHODS

We performed an electronic health care records search on AP patients treated at Emergency University Hospital of Bucharest (Spitalul Universitar de Urgență București) between 2015 and 2022. The incidence, etiology, and severity were calculated; potential risk factors were evaluated, and the hospitalization costs of AP were documented and analyzed. The cohort of this study is part of the BUCharest - Acute Pancreatitis Index registry.

RESULTS

A total of 947 consecutive episodes of AP where the patients were hospitalized in the gastroenterology department were analyzed, with 79.45% as 1^st episode and the rest recurrent. The majority of the patients were males (68.9%). Alcoholic (45.7%), idiopathic (16.4%) and biliary (15.2%) were the main causes. The incidence was estimated at 29.2 episodes/100000 people. The median length of stay was 7 d. The median daily cost was 747.96 RON (165 EUR). There was a high prevalence of active tobacco smokers (68.5%). The prevalence of severe disease was 11.1%. The admission rate to the intensive care unit was 4.6%, with a mortality rate of 38.6%. The overall mortality was 5.5%.

CONCLUSION

We estimated the incidence of AP at 29.2 episodes that required hospitalization per 100000 people. The majority of our cases were found in males (68.9%) and were related to alcohol abuse (45.7%). Out of the cases we were able to find data regarding tobacco usage, the majority were active smokers (68.5%). Most patients had a mild course (54.4%), with a mortality rate of 5.5%. Interstitial AP prevailed (45.3%). The median daily cost of hospitalization was 747.96 RON (165 EUR).

Tissue and Circulating MicroRNA-31, MicroRNA-200b, and MicroRNA-200c Reflects Disease Activity in Crohn's Disease Patients: Results from the BIOMIR Study

BACKGROUND AND AIMS

MicroRNAs (miR) have altered expression in multiple autoimmune disorders including inflammatory bowel disease. The aim of the study was to assess the tissue and circulating miR-31, miR-200b, and miR-200c expression levels as potential biomarkers for intestinal disease activity in patients with Crohn's disease (CD).

METHODS

The study included 45 patients with histopathological confirmed CD and active disease (defined as fecal calprotectin >50 μg/g and Simple Endoscopic Score (SES) of CD >3), and 21 subjects as controls for the validation cohort. Demographic and clinical data, biomarkers (fecal calprotectin), endoscopy data, the expression levels of miR-31, miR-200b, and miR-200c in tissue and serum were assessed (by RT-PCR). Receiver operating characteristic analysis was performed to assess the miR-31, miR-200b, and miR-200c expression levels as potential biomarkers for active CD.

RESULTS

Mean fecal calprotectin was 1540±890 μg/g. Mean SES-CD was 8.9±4.2. Tissue and circulating miR- 31 were significantly correlated with fecal calprotectin (r=0.81, r=0.83, p<0.01) and with SES-CD (r=0.82, r=0.79, p<0.01). The expression level of miR-31 was significantly upregulated in CD tissue cases compared to the control tissue samples (6.24±1.57 vs. 3.70±1.44; p <0.01). Similarly, serum miR-31 expression levels in CD patients were significantly upregulated compared to the control serum samples (0.78±0.42 vs. -2.07±1.00; p<0.01). The expression levels of tissue miR-200b and miR-200c were significantly upregulated in CD tissue cases compared to the control tissue samples (-5.25±0.93 vs. -4.69±0.80, p=0.03 for miR-200b, and -0.86±0.96 vs. 0.39±0.66, p<0.01 for miR-200c). Similarly, serum miR-200b and miR-200c expression levels in CD patients were significantly upregulated compared to the control serum samples (p < 0.05). Receiver operating characteristic analysis revealed that the expression levels of the selected miRNAs could help to discriminate active CD patients from healthy controls with very good specificity and sensitivity.

CONCLUSIONS

Tissue and circulating miR-31, miR-200b, and miR-200c reflect disease activity in CD patients and can be used as biomarkers for active disease.

Romanian Guidelines for the Diagnosis and Treatment of GERD-induced Respiratory Manifestations

BACKGROUND AND AIMS

Gastroesophageal reflux disease (GERD) is a common condition present in daily practice with a wide range of clinical phenotypes. In this line, respiratory conditions may be associated with GERD. The Romanian Societies of Gastroenterology and Neurogastroenterology, in association with the Romanian Society of Pneumology, aimed to create a guideline regarding the epidemiology, diagnosis and treatment of respiratory conditions associated with GERD.

METHODS

Delphi methodology was used and eleven common working groups of experts were created. The experts reviewed the literature according to GRADE criteria and formulated 34 statements and recommendations. Consensus (>80% agreement) was reached for some of the statements after all participants voted.

RESULTS

All the statements and the literature review are presented in the paper, together with their correspondent grade of evidence and the voting results. Based on >80% voting agreement, a number of 22 recommendations were postulated regarding the diagnosis and treatment of GERD-induced respiratory symptoms. The experts considered that GERD may cause bronchial asthma and chronic cough in an important number of patients through micro-aspiration and vagal-mediated tracheobronchial reflex. GERD should be suspected in patients with asthma with suboptimal controlled or after exclusion of other causes, also in nocturnal refractory cough which needs gastroenterological investigations to confirm the diagnosis. Therapeutic test with double dose proton pump inhibitors (PPI) for 3 months is also useful. GERD induced respiratory conditions are difficult to treat; however,proton pump inhibitors and laparoscopic Nissen fundoplication are endorsed for therapy.

CONCLUSIONS

This guideline could be useful for the multidisciplinary management of GERD with respiratory symptoms in current practice.

Surrogate markers of mucosal healing in inflammatory bowel disease: A systematic review

BACKGROUND

Mucosal healing (MH) has emerged as a key therapeutic target in inflammatory bowel disease (IBD), and achievement of this goal is documented by endoscopy with biopsy. However, colonoscopy is burdensome and invasive, and substitution with an accurate noninvasive biomarker is desirable.

AIM

To summarize published data regarding the performance of noninvasive biomarkers in assessing MH in IBD patients.

METHODS

We conducted a systematic review of studies that reported the performance of biomarkers in diagnosing MH in patients with IBD. The main outcome measure was to review the diagnostic accuracy of serum and fecal markers that showed promising utility in assessing MH.

RESULTS

We screened 1301 articles, retrieved 46 manuscripts and included 23 articles for full-text analysis. The majority of the included manuscripts referred to fecal markers (12/23), followed by circulatory markers (8/23); only 3/23 of the included manuscripts investigated combined markers (serum and/or fecal markers). Fecal calprotectin (FC) was the most investigated fecal marker for assessing MH. In ulcerative colitis, for cutoff levels ranging between 58 mcg/g and 490 mcg/g, the sensitivity was 89.7%-100% and the specificity was 62%-93.3%. For Crohn’s disease, the cutoff levels of FC ranged from 71 mcg/g to 918 mcg/g (sensitivity 50%-95.9% and specificity 52.3%-100%). The best performance for a serum marker was observed for the endoscopic healing index, which showed a comparable accuracy to the measurement of FC and a higher accuracy than the measurement of serum C-reactive protein.

CONCLUSION

Several promising biomarkers of MH are emerging but cannot yet substitute for endoscopy with biopsy due to issues with reproducibility and standardization.

Endoscopy in inflammatory bowel disease: from guidelines to real life

Endoscopy has a central role in the management of inflammatory bowel disease (IBD), providing crucial data for diagnostic and therapeutic decisions, treating disease-related complications, and assisting in the early detection of dysplasia and prevention of colorectal cancer in the setting of IBD. Treatment targets have significantly shifted in IBD, focusing on achieving mucosal healing, a more meaningful endpoint than clinical remission. With the emergence of novel therapies, we aim to alter the course of the disease and prevent irreversible damage to the bowel. To that end, obtaining reliable and reproducible assessments of endoscopic disease activity has become an issue of great importance. Although several guidelines include recommendations regarding endoscopic surveillance in patients with long-standing IBD, there is an open debate regarding the best examination method and the appropriate follow-up intervals. Another important issue is whether surveillance guidelines are actually implemented in real-life practice and what is the preferred surveillance method among endoscopists. Significant changes have occurred in the endoscopic world with the development of new diagnostic and therapeutic modalities and their incorporation in everyday practice. We aimed to assess the real-life application of guideline recommendations regarding endoscopy in IBD patients and to review newly emerged data which might impact these recommendations in the near future.

Role of new endoscopic techniques in inflammatory bowel disease management: Has the change come?

Despite significant therapeutic progress in recent years, inflammatory bowel disease (IBD), which includes Crohn’s disease and ulcerative colitis, remains a challenge regarding its pathogenesis and long-term complications. New concepts have emerged in the management of this disease, such as the “treat-to-target” concept, in which mucosal healing plays a key role in the evolution of IBD, the risk of recurrence and the need for surgery. Endoscopy is essential for the assessment of mucosal inflammation and plays a pivotal role in the analysis of mucosal healing in patients with IBD. Endoscopy is also essential in the detection of dysplasia and in the identification of the risk of colon cancer. The current surveillance strategy for dysplasia in IBD patients indicates white-light endoscopy with non-targeted biopsies. The new chromoendoscopy techniques provide substantial benefits for both clinicians and patients. Narrow-band imaging (NBI) has similar rates of dysplastic lesion detection as white-light endoscopy, and it seems that NBI identifies more adenoma-like lesions. Because it is used instinctively by many endoscopists, the combination of these two techniques might improve the rate of dysplasia detection. Flexible spectral imaging color enhancement can help differentiate dysplastic and non-dysplastic lesions and can also predict the risk of recurrence, which allows us to modulate the treatment to gain better control of the disease. The combination of non-invasive serum and stool biomarkers with endoscopy will improve the monitoring and limit the evolution of IBD because it enables the use of a personalized approach to each patient based on that patient’s history and risk factors.

Colon capsule endoscopy leading to gastrointestinal stromal tumor (GIST) diagnosis after colonoscopy failure

Background

Gastrointestinal stromal tumors are a subtype of mesenchymal tumors. In recent years a significant progress was made in their diagnosis and treatment which led to significant improvement of their prognosis. Endoscopy remains one of the main diagnostic methods. In the rare instance of colonoscopy failure, different approaches are available: different endoscope, computed tomography colonography, capsule endoscopy, use of an enteroscope.

Case presentation

We present the case of a 75-year-old Caucasian man admitted for abdominal pain, diarrhea and weight loss. Two colonoscopy attempts failed in a different center and a decision to use colon capsule endoscopy was made. This exam revealed a submucosal mass located in the sigmoid colon. Surgery was performed and a local invading gastrointestinal stromal tumor was removed. This is the first image of a colonic gastrointestinal stromal tumor seen on capsule endoscopy.

Conclusion

Colon capsule is a useful diagnostic tool in selected patients after colonoscopy failure or contraindication.

Cardiovascular involvement in inflammatory bowel disease: Dangerous liaisons

Increasing evidence of a link between inflammatory bowel disease (IBD) and adverse cardiovascular events has emerged during the last decade. In 2014, an important number of meta-analyses and cohort studies clarified the subtle dangerous liaisons between gut inflammation and cardiovascular pathology. The evidence suggests that patients with IBD have a significantly increased risk of myocardial infarction, stroke, and cardiovascular mortality, especially during periods of IBD activity. Some populations (e.g., women, young patients) may have an even greater risk. Current effective treatment of IBD is aimed at disease remission and seems to reduce cardiovascular risk in these patients. A beneficial effect was demonstrated for salicylates, but not for steroids or azathioprine. tumor necrosis factor-α antagonists, which are highly effective in the reduction of inflammation and in the restoration of the digestive mucosa, lead to conflicting cardiovascular effects, as they seem to reduce the risk for ischemic heart disease but increase the rate of cerebrovascular events. Future supplemental treatment strategies that may reduce the atherothrombotic risk during periods of IBD activity should be explored.

PillCam Colon 2 capsule in patients unable or unwilling to undergo colonoscopy

AIM: To assess the feasibility, accuracy and acceptability of PillCam Colon 2 in detection of significant lesions in colorectal cancer risk patients, unable or unwilling to perform colonoscopy.

METHODS: This is a prospective, single center study using the second generation of PillCam Colon capsule. In all patients the readers were instructed to review the entire colon capsule endoscopy (CCE) examination using Rapid 7 software and additionally to note significant extra-colonic findings. Colonic significant findings were described according to European Society of Gastrointestinal Endoscopy guidelines. CCE procedure completion rate, level of bowel preparation and rate of adverse events were assessed.

RESULTS: A total of 70 patients at risk of colorectal cancer were enrolled in the study. In three patients the procedure failed because the capsule was not functioning when entered the colon. PillCam Colon 2 showed positive findings in 23 (34%, 95%CI: 21.6%-44.1%) of the remaining 67 patients. Six patients were diagnosed with tumors: 4 with colon cancers, 1 with gastric cancer and 1 with a small bowel cancer. The capsule findings were confirmed after surgery in all these patients. The capsule excretion rate in twelve hours was 77% with 54 patients having a complete examination. The rectum was not explored during CCE procedure, in 16 patients (23%, 95%CI: 13.7%-34.1%). Every patient accepted CCE as an alternative exploration tool and 65/70 (93%) agreed to have another future control by CCE. No complications were reported during or after CCE examination.

CONCLUSION: PillCam Colon 2 capsule was effective in detecting significant lesions and might be considered an adequate alternative diagnostic tool in patients unable or unwilling to undergo colonoscopy.

Role of capsule endoscopy Pillcam COLON 2 in patients with known or suspected Crohn's disease who refused colonoscopy or underwent incomplete colonoscopic exam: a case series

BACKGROUND

Almost 70-80 % of patients with Crohn's disease and virtually all patients with ulcerative colitis have colorectal mucosa involvement. Colon capsule endoscopy is an interesting option for patients unable or unwilling to undergo colonoscopy. We report our experience with the second-generation colon capsule PillCam(®) COLON 2 in the detection of significant lesions in patients with known or suspected Crohn's disease, who refused colonoscopy or underwent incomplete colonoscopic exam.

METHODS

We have retrospectively reviewed the results of capsule endoscopy in 6 patients who refused colonoscopy (n = 3) or underwent incomplete colonoscopic exam (n = 3) between March 2011 and October 2012. In all patients, a CT scan was obtained before capsule endoscopy to rule out significant stenosis.

RESULTS

In our series of 6 patients, 4 had both small bowel and colonic involvement. The use of the PillCam(®) COLON 2 capsule allowed a thorough examination and evaluation of the mucosal lesions with high acceptability, the method being perceived as noninvasive by the patients. No adverse events related to the capsule or bowel preparation were recorded.

CONCLUSION

In this patient population, PillCam(®) COLON 2 capsule endoscopy was safe. The capsule findings had an important impact on treatment decisions and patient management.

First Pillcam Colon 2 capsule images of Whipple’s disease: Case report and review of the literature

Whipple’s disease is a rare chronic systemic infection determined by the Gram-positive bacillus Tropheryma whipplei. The infection usually mainly involves the small bowel, but sometimes other organs are affected as well. Since the current standard clinical and biological tests are nonspecific, diagnosis is very difficult and relies on histopathology. Here we present the case of a 52-year-old man with chronic diarrhea and weight loss whose symptoms had been evolving for 2 years and whose diagnosis came unexpectedly after capsule examination. Diagnosis was confirmed by the histopathologic examination of endoscopic biopsy samples, and treatment with co-trimoxazole resulted in remission of symptoms. We present the first images of Whipple’s disease obtained with the Pillcam Colon 2 video capsule system.

Duodopa infusion treatment: a point of view from the gastroenterologist

In patients with advanced Parkinson's disease, the continuous delivery to the small intestine via a jejunal tube of levodopa/carbidopa, formulated as a gel suspension (Duodopa) represents a new treatment method. The continuous release results in less variability in levodopa concentrations and fewer motor fluctuations and dyskinesias than with oral administration. The method which requires a very good collaboration between the neurologist and the gastroenterologist is used with increasing frequency in selected centres especially in severe patients. First, a classic PEG gastrostomy kit is placed under propofol sedation. This allows the passage of a pig tail catheter which is deployed in the jejunum and it is attached to a portable pump via a special tubing system. We present our experience of seven cases (5 males, mean age 60 years) with a follow up of one year. One patient died due to respiratory failure and aspiration pneumonia probably related to the endoscopic procedure. At one year, all patients agreed that the neurological benefit offsets the procedure related problems and the technical issues related to the enteral infusion system.

Evaluation of successful treatment in achalasia with timed barium esophagogram: revisiting an old friend

Achalasia is a rare idiopathic, primary esophageal motility disorder. Pharmacologic, endoscopic and surgical methods are used in its treatment. The efficiency of the treatment is generally based on clinical "subjective" criteria. Manometry, which is the gold standard in diagnostic and in treatment monitoring is not always available, it is costly and it needs expertise. The role of timed barium esophagogram in the evaluation of the patients before and after endoscopic dilation will be discussed in the article. This method is standardized, less costly, and has a good correlation with clinical and manometrical results.

Interstitial cells of Cajal in the gut - A gastroenterologist’s point of view

Alterations of normal function of interstitial cells of Cajal (ICC) are reported in many intestinal disorders. Diagnosis of their involvement is rare (infrequent), but necessary to propose a specific treatment. This article reviews the place of ICC in the pathogenesis of achalasia, gastroesophageal reflux disease, infantile hypertrophic pyloric stenosis, chronic intestinal pseudo-obstruction and slow transit constipation. Moreover we discuss the role of the Cajal cells in the development of stromal tumors of the gastrointestinal tract.

An endoscopic view in gastric linitis. A case report

A case of an 84 year old woman addressed for dysphagia is discussed. The endoscopic and histologic examination revealed a gastric linitis with cardial invasion. Classically, there is no characteristic macroscopic description associated with gastric linitis. An endoscopic aspect considered highly suggestive for gastric linitis is presented.

Portal hypertensive gastropathy

Portal hypertensive gastropathy (PHG) is the term used to describe the endoscopic appearance of gastric mucosa seen in patients with cirrhotic or non-cirrhotic portal hypertension with a characteristic mosaic-like pattern with or without red spots. The prevalence of PHG varies from 50% to 98%, this variation of the prevalence being perhaps related to patient selection, inter- and intra-observer variation and absence of uniform criteria and classification. About 8% of the upper digestive hemorrhages in the cirrhotic patients are secondary to PHG. There is no general consensus on the endoscopic classification of PHG (the most New Italian Endoscopy Club). The exact pathogenesis of PHG is not completely understood, but the portal hypertension is the main factor involved in its development and not the severity of the hepatic disease. Gastric Antral Vascular Ectasia (GAVE) is a term used for the typical endoscopic findings of red stripes, separated by normal mucosa, most frequently seen in the gastric antrum or proximal stomach. Current therapy of PHG includes beta blockers, somatostatin and derivates, endoscopic and surgical methods including hepatic transplantation.
