Over-the-scope clip and self-expandable metal stent: a comprehensive treatment for failed peroral endoscopic myotomy and fibrosis complications in idiopathic achalasia
Achalasia is a rare esophageal motility disorder that affects both sexes and all ages. Peroral endoscopic myotomy (POEM) has been reported as an optional treatment since 2010 [1]. Frequently associated adverse events include pneumoperitoneum, pneumomediastinum, and pneumothorax, which are usually asymptomatic and managed conservatively [2, 3]. Perforation, bleeding, mediastinitis, and peritonitis rarely occur and are often symptomatic. Mucosal injuries (including dehiscence, ulcer, and ischemia) do not alter the post-procedural course [4]. A 31-year-old man, affected by idiopathic achalasia, was admitted as an outpatient to our Gastroenterological Unit owing to symptom recurrence and weight loss (Eckardt score 8). Two years before, he had undergone POEM, which was complicated by pneumomediastinum and ischemic damage of the distal esophagus with residual fibrosis. An esophagogram revealed a dilated
esophagus (maximum diameter 60mm) and supracardial stricture extending 15 mm above. His dysphagia was most likely worsened by post-POEM complications. We planned to place a fully covered removable metal stent (SEMS; 60 Ă— 27mm) to achieve progressive, effective dilation of the distal esophagus . The SEMS would be firmly fixed by means of an over-the-scope (OTS) clip. This novel OTS clip device has demonstrated success in reducing SEMS migration even in benign diseases [5]. The SEMS was released 10mm above the post-POEM stricture, 25 mm above the cardia, and fixed by means of the OTS
clip. The patient was discharged uneventfully on the same day. An alternative approach (Heller myotomy) was ready to be employed in case of failure. At the 4-week follow-up, dysphagia had improved and the patient had gained weight. Both the OTS clip and the SEMS were removed using the remOVE device (Ovesco Endoscopy AG, Tübingen, Germany) . The patient was discharged uneventfully 12 hours later. After a further 4 weeks, an esophagogram revealed a significant reduction in the esophagus dilation and the patient’s clinical condition had significantly improved (Eckardt score 0)

Cytomegalovirus infection in IBD patients undergoing anti-TNF-alpha therapy
CMV infection is frequent in pts treated with immunosuppressive drugs and may be associated
with steroid refractoriness and poor outcome in IBD pts. No data are available on the effect
of anti-TNF- treatment on prevalence and clinical course of CMV infection and disease
in IBD. We assessed the severity of active CMV infection and disease in 11consecutive pts with
ileocolonic/colonic Crohn’s disease and 4 pts with ulcerative colitis (10 males, 5 females,
mean age 50,2 18.1 SD) before and after a standard 3-infusion course of Infliximab for
fistulizing disease in 8 pts, steroid-dependent/refractory disease in 7. Six pts were on cortisone
during the first observation and 9 on azathioprine. All pts received azathioprine after the
first anti-TNF infusion. Seroprevalence of CMV infection was evaluated by serology. Active
CMV infection was diagnosed by means of pp65-antigenemia (pp65-AG). CMV disease was
assessed on haematoxylin/ eosin-stained colonic biopsies, quantisation of CMV DNA by a
quantitative PCR kit (Amplification set CMV Hybridoquant, Bioline, Italy), allowing amplification
of a minimum of 100 copies/ug of DNA isolated from colonic biopsies.
Results: All pts but 2 were positive for anti-CMV. One patient had positive pp65-AG before
and after Infliximab. In 2 pts CMV was diagnosed by conventional histology. CMV DNA
was present before therapy in 3 pts (130-1340 copies/ug of DNA) and in 2 of them only
(410 and 1300 copies/ug DNA) after therapy. The histological inflammation in colonic tissue
improved after anti-TNF- in all CMV-positive pts but one of the 2 pts positive for CMV
DNA in which it remained unchanged.
Discussion: The prevalence of active CMV infection and disease assessed by means of pp65-
AG, conventional histology and competitive quantitative PCR on colonic DNA extracts didn’t
vary after Infliximab. In pts who had active CMV infection and disease before anti-TNF- ,
the severity of colonic mucosal inflammation did not worsen and the number of copies/ng
DNA from colonic DNA extracts did not increase following therapy. This proved true also
in the 2 pts with severe colitis and serum or tissue CMV DNA positivity. Conversely one
pt became CMV DNA-negative after the course of anti-TNF . Despite the reports of increased
active CMV infection resulting from post-transplant immunosuppression, these preliminary
data suggest that the problem may not be relevant in IBD patients undergoing a course of
cortisone, azathioprine and anti-TNF-
The Italian registry of therapeutic apheresis: Granulocyte-monocyte apheresis in the treatment of inflammatory bowel disease. A multicentric study
Leukocytes are thought to play an important role in the pathogenesis of inflammatory bowel diseases; granulocyte-monocyte adsorptive (GMA) apheresis, an extracorporeal technique aimed at removing activated circulating leukocytes from the blood, may represent a safe and effective therapeutic tool in these patients. The Italian Registry of Therapeutic Apheresis performed an observational, multicentric study involving 24 Gastroenterology Units. In this study, laboratory data and clinical outcomes of 230 patients (148 males, mean age 43.5 years) affected with ulcerative colitis (UC, n = 194) or Crohn's disease (CD, n = 36) who underwent one or more cycles of GMA were analyzed. Each cycle consisted of five GMA treatments. The patients were followed up for a mean of 8.7 (min. 3 to max. 12) months. At 3 months, positive outcome was achieved in 77.7% of UC patients (72.0% remission, 5.7% clinical response) and 61.3% of CD patients (54.8% remission, 6.5% clinical response). The cumulative proportion of positive outcome at 12 months was 87.1% for UC patients (83.7% remission, 3.4% clinical response) and 77.4% for CD patients (74.2% remission, 3.2% clinical response). No single clinical or laboratory parameter among those analyzed (age, sex, disease characteristics, history of smoking, medication history, baseline values of clinical activity index (CAI)/Crohn's disease activity index (CDAI), hemoglobin, white blood cells count, and erythrocyte sedimentation rate) was independently associated with clinical outcome. The procedure was well tolerated with no significant adverse effects registered. © 2011 Wiley Periodicals, Inc
Poliprotect vs Omeprazole in the Relief of Heartburn, Epigastric Pain, and Burning in Patients Without Erosive Esophagitis and Gastroduodenal Lesions: A Randomized, Controlled Trial
Introduction: In the treatment of upper GI endoscopy-negative patients with heartburn and epigastric pain or burning, antacids, antireflux agents, and mucosal protective agents are widely used, alone or as add-on treatment, to increase response to proton-pump inhibitors, which are not indicated in infancy and pregnancy and account for significant cost expenditure. Methods: In this randomized, controlled, double-blind, double-dummy, multicenter trial assessing the efficacy and safety of mucosal protective agent Poliprotect (neoBianacid, Sansepolcro, Italy) vs omeprazole in the relief of heartburn and epigastric pain/burning, 275 endoscopy-negative outpatients were given a 4-week treatment with omeprazole (20 mg q.d.) or Poliprotect (5 times a day for the initial 2 weeks and on demand thereafter), followed by an open-label 4-week treatment period with Poliprotect on-demand. Gut microbiota change was assessed. Results: A 2-week treatment with Poliprotect proved noninferior to omeprazole for symptom relief (between-group difference in the change in visual analog scale symptom score: [mean, 95% confidence interval] -5.4, -9.9 to -0.1; -6.2, -10.8 to -1.6; intention-to-treat and per-protocol populations, respectively). Poliprotect's benefit remained unaltered after shifting to on-demand intake, with no gut microbiota variation. The initial benefit of omeprazole was maintained against significantly higher use of rescue medicine sachets (mean, 95% confidence interval: Poliprotect 3.9, 2.8-5.0; omeprazole 8.2, 4.8-11.6) and associated with an increased abundance of oral cavity genera in the intestinal microbiota. No relevant adverse events were reported in either treatment arm. Discussion: Poliprotect proved noninferior to standard-dose omeprazole in symptomatic patients with heartburn/epigastric burning without erosive esophagitis and gastroduodenal lesions. Gut microbiota was not affected by Poliprotect treatment. The study is registered in Clinicaltrial.gov (NCT03238534) and the EudraCT database (2015-005216-15)
