High-risk Brugada syndrome: factors associated with arrhythmia recurrence and benefits of epicardial ablation in addition to implantable cardioverter defibrillator implantation.

AIMS: This study aims to evaluate the prognostic impact of the arrhythmogenic substrate size in symptomatic Brugada syndrome (BrS) as well as to validate the long-term safety and effectiveness of epicardial radiofrequency ablation (RFA) compared with no-RFA group. METHODS AND RESULTS: In this prospective investigational long-term registry study, 257 selected symptomatic BrS patients with implantable cardioverter defibrillator (ICD) implantation were included. Among them, 206 patients underwent epicardial RFA and were monitored for over 5 years post-ablation (RFA group), while 51 patients received only ICD implantation declining RFA. Primary endpoints included risk factors for ventricular fibrillation (VF) events pre-ablation and freedom from VF events post-ablation. In the RFA group, BrS substrates were identified in the epicardial surface of the right ventricle. During the pre-RFA follow-up period (median 27 months), VF episodes and VF storms were experienced by 53 patients. Independent risk factors included substrate size [hazard ratio (HR), 1.13; 95% confidence interval (CI), 1.08-1.18; P < 0.001], aborted cardiac arrest (HR, 2.98; 95% CI, 1.68-5.28; P < 0.001), and SCN5A variants (HR, 2.22; 95% CI, 1.15-4.27; P = 0.017). In the post-RFA follow-up (median 40 months), the RFA group demonstrated superior outcomes compared with no-RFA (P < 0.001) without major procedure-related complications. CONCLUSION: Our study underscores the role of BrS substrate extent as a crucial prognostic factor for recurrent VF and validates the safety and efficacy of RFA when compared with a no-RFA group. Our findings highlight the importance of ajmaline in guiding epicardial mapping/ablation in symptomatic BrS patients, laying the groundwork for further exploration of non-invasive methods to guide informed clinical decision-making.

An Objective Comparison of Vedolizumab and Ustekinumab Effectiveness in Crohn's Disease Patients' Failure to TNF-Alpha Inhibitors.

INTRODUCTION: The use of ustekinumab and vedolizumab as second-line therapies in patients with Crohn's disease (CD) in which tumour necrosis factor alpha inhibitors (TNFi) failed is still debated. The aim of this study was to compare, in a large multicenter observational retrospective cohort, the effectiveness of ustekinumab and vedolizumab as second-line therapies, as assessed by clinical and objective outcomes including endoscopy and gastrointestinal imaging. METHODS: Clinical response, remission, and steroid-free remission at weeks 26 and 52 were evaluated in a retrospective propensity score-weighted and propensity score-matched cohort of patients in which TNFi failed. Objective response and remission were evaluated by 1 or more techniques among endoscopy, magnetic resonance/computed tomography enteroclysis, and small bowel ultrasound. RESULTS: A total of 470 patients with CD (239 treated with ustekinumab and 231 treated with vedolizumab) were included in the study. At week 26, clinical outcomes were similar between the 2 groups. At week 52, clinical remission (ustekinumab 42.5% vs vedolizumab 55.5%, P = 0.01) and steroid-free remission (ustekinumab 40.6% vs vedolizumab 51.1%, P = 0.038) rates were significantly higher in vedolizumab-treated patients. Three hundred two patients (hundred thirty-five treated with ustekinumab and hundred sixty-seven treated with vedolizumab) had an objective evaluation of disease activity at baseline and week 52. At week 52, objective response and remission rates were similar between the 2 groups. Clinical response at week 26 predicted steroid-free remission at week 52 in both ustekinumab-treated and vedolizumab-treated patients. Safety profiles were similar between the 2 groups. DISCUSSION: In patients with CD in which TNFi failed, both ustekinumab and vedolizumab showed similar clinical effectiveness after 26 weeks of treatment. At 1 year, vedolizumab was associated with a higher rate of clinical remission when compared with ustekinumab. However, no difference was observed between the 2 groups when objective outcomes were investigated at this time point.

The Conversion of Planned Colonoscopy to Sigmoidoscopy and the Effect of this Practice on the Measurement of Quality Indicators.

OBJECTIVES: A cecal intubation rate (CIR) of >90% is a well-accepted quality indicator of colonoscopy and is consequently monitored within endoscopy units. Endoscopists' desire to meet this target may mean that incomplete colonoscopies are recorded as flexible sigmoidoscopies. The aim of this study was to examine whether the conversion of requested colonoscopies is a clinically significant phenomenon and whether this impacts upon the measurement of quality indicators. METHODS: A retrospective review of all flexible sigmoidoscopies performed between 1 January 2015 and 31 December 2015 at Nottingham University Hospitals, Sheffield Teaching Hospitals, and Cambridge University Hospitals was performed. Where a colonoscopy was requested but a flexible sigmoidoscopy performed, the patient's records and endoscopy reports were reviewed to determine whether this conversion was decided before the start of the procedure and documented. RESULTS: During the 12-month period, 6,839 flexible sigmoidoscopies were performed by 125 endoscopists. The original requests of 149 sigmoidoscopies could not be retrieved and were therefore excluded from this analysis. Of the 6,690 sigmoidoscopy requests reviewed, 2.8% (n=190) procedures were originally requested as a colonoscopy. On review of patient records, 85 conversions were appropriate according to pre-defined criteria. However, 105 conversions were deemed inappropriate, occurring in patients who had a valid documented indication for colonoscopy and had undergone full bowel preparation. The most common reasons cited included poor bowel preparation (n=37), technically challenging procedure (n=24), at the endoscopist's discretion based on clinical factors (n=21), and obstructing patology (n=8). A clear reason for conversion was not apparent in 11 cases. During the study period, 21,271 colonoscopies were performed and so conversions represent 0.45% of the total requests. When inappropriate conversions were included in individuals' performance data, 15 endoscopists fell to ≤90% target cecal intubation target. CONCLUSIONS: A small, but significant number of colonoscopies are converted to flexible sigmoidoscopies at the time of the procedure. This study demonstrates the conversion of colonoscopy to sigmoidoscopy as being a potential limitation of relying on CIR alone. Endoscopy units should consider monitoring the rate of inappropriate conversions to ensure quality.

Risk of gastrointestinal complications associated to NSAIDs, low-dose aspirin and their combinations: Results of a pharmacovigilance reporting system.

Gastrointestinal (GI) complications are one of the most limiting cause of use of NSAIDs. Beyond others well defined factors, history of peptic ulcer, older age, Helicobacter pylori infection and use of gastrotoxic drugs may affect their GI safety profile. In particular, the risk of GI complications associated to the use of antiplatelet drugs, especially low-dose acetylsalicylic acid (LDA) should deserve much attention. However, only few studies have focused on the effect of combination LDA/NSAIDs on the GI tract compared with the monotherapy and much less studies assessed this effect with multiple NSAIDs use. We aimed to characterize the GI safety profile of NSAIDs and LDA as monotherapy or their combinations in real-life conditions by analysing spontaneous adverse drug reactions (ADRs) reporting system in a Southern Italy. We used the case/non-case method in the Italian Pharmacovigilance Network (RNF). Cases were reports of GI events in the RNF between January 2007 and December 2011. Non-cases were all other reports during the same period. The association between NSAID and suspected GI ADRs was calculated using the reporting odds ratio (ROR) with 95% confidence intervals as a measure of disproportionality while adjusting for age, and concomitant use of antineoplastic agents or drugs for cardiovascular diseases. Sub-analysis were performed within the NSAID class. Among the 2816 adverse drug reactions recorded, we identified 374 (13.3%) cases of GI complications. Upper GI complications were the most frequently reported type of events. The highest associations were found for the combined use of NSAIDs and/or LDA, whilst the lowest associations were for their respective monotherapy. Looking at individual NSAIDs the highest association with GI events was observed for ketorolac exposure followed by nimesulide, diclofenac, aspirin, ketoprofen, and ibuprofen. This study highlights the primary role of the national spontaneous reporting system to bring out potential signals, such as the inappropriate drug use pattern, which however, have to be furtherly studied in-depth with ad hoc population-based studies.

Dactylitis in enteropathic spondyloarthritis.

OBJECTIVES: Dactylitis has long been recognised as one of the significant features of spondyloarthropathies. In the literature, the prevalence of dactylitis in enteropathic spondyloarthritis (EASpA) ranges between 2% and 4%. The aim of this study was to identify the prevalence of dactylitis in EASpA patients and to investigate its association with clinical subset and with articular and bowel disease activity. METHODS: 78 EASpA patients and 78 controls were enrolled for this study. All patients and controls underwent a rheumatological and a gastroenterological clinical examination. Demographic and clinical features were recorded. Diagnosis of dactylitis was made by physical examination and was evaluated using the Leeds Dactylitis Instrument (LDI). RESULTS: In our study the prevalence of dactylitis in EASpA was 15.38%, mainly in patients with Crohn's disease (CD) and peripheral arthritis. A significantly higher articular and bowel disease activity was found in patients with dactylitis compared to those without it. The family history of psoriasis represented a predictor of occurrence of dactylitis. Finally, a significant correlation between disease activity and LDI score was found in EASpA. CONCLUSIONS: The results of our study showed a high prevalence of dactylitis in EASpA. It was more frequent in patients with CD and peripheral involvement with a higher articular disease activity, confirming that dactylitis may be a severity marker and a prognostic factor for EASpA. The significant correlation between disease activity and LDI score could address LDI as a potential tool of assessment of dactylitis.

Italian translation and cultural adaptation of the communication assessment tool in an outpatient surgical clinic.

BACKGROUND: The aim of the study is to translate and cross-culturally adapt, for use in the Italian context, the Communication Assessment Tool (CAT) developed by Makoul and colleagues. METHODS: The study was performed in the out-patient clinic of the Surgical Department of Cardarelli Hospital in Naples, Italy. It involved a systematic, standardized, multi-step process adhering to internationally accepted and recommended guidelines. Corrections and adjustments to the translation addressed both linguistic factors and cultural components. RESULTS: The CAT was translated into Italian by two independent Italian mother-tongue translators. The consensus version was then back-translated by an English mother-tongue translator. This translation process was followed by a consensus meeting between the authors of translation and investigators, and then by two comprehension tests on a total of 65 patients. CONCLUSIONS: Results of the translation and cross-cultural adaptation were satisfactory and indicate that the Italian translation of the CAT can be used with confidence in the Italian context.

Wolff-Parkinson-White syndrome in the era of catheter ablation: insights from a registry study of 2169 patients.

BACKGROUND: The management of Wolff-Parkinson-White is based on the distinction between asymptomatic and symptomatic presentations, but evidence is limited in the asymptomatic population. METHODS AND RESULTS: The Wolff-Parkinson-White registry was an 8-year prospective study of either symptomatic or asymptomatic Wolff-Parkinson-White patients referred to our Arrhythmology Department for evaluation or ablation. Inclusion criteria were a baseline electrophysiological testing with or without radiofrequency catheter ablation (RFA). Primary end points were the percentage of patients who experienced ventricular fibrillation (VF) or potentially malignant arrhythmias and risk factors. Among 2169 enrolled patients, 1001 (550 asymptomatic) did not undergo RFA (no-RFA group) and 1168 (206 asymptomatic) underwent ablation (RFA group). There were no differences in clinical and electrophysiological characteristics between the 2 groups except for symptoms. In the no-RFA group, VF occurred in 1.5% of patients, virtually exclusively (13 of 15) in children (median age, 11 years), and was associated with a short accessory pathway antegrade refractory period (P<0.001) and atrioventricular reentrant tachycardia initiating atrial fibrillation (P<0.001) but not symptoms. In the RFA group, ablation was successful in 98.5%, and after RFA, no patients developed malignant arrhythmias or VF over the 8-year follow-up. Untreated patients were more likely to experience malignant arrhythmias and VF (log-rank P<0.001). Time-dependent receiver-operating characteristic curves for predicting VF identified an optimal anterograde effective refractory period of the accessory pathway cutoff of 240 milliseconds. CONCLUSIONS: The prognosis of the Wolff-Parkinson-White syndrome essentially depends on intrinsic electrophysiological properties of AP rather than on symptoms. RFA performed during the same procedure after electrophysiological testing is of benefit in improving the long-term outcomes.

Oral prolonged release beclomethasone dipropionate and prednisone in the treatment of active ulcerative colitis: results from a double-blind, randomized, parallel group study.

OBJECTIVES: Double-blind study comparing efficacy and safety of the topically acting corticosteroid beclomethasone dipropionate (BDP) to prednisone (PD) in patients with active, mild-to-moderate ulcerative colitis (UC). METHODS: Overall, 282 patients were randomized to receive BDP-prolonged release tablets 5 mg once daily for 4 weeks and then every other day for an additional 4 weeks or oral PD 40 mg once daily for the initial 2 weeks tapered of 10 mg every 2 weeks during the 8-week study period. Efficacy end point was the non-inferiority of BDP vs. PD in terms of Disease Activity Index (DAI) score <3 or reduction by at least 3 points for patients with a baseline DAI ≥7 at week 4. Safety end point was the proportion of patients with steroid-related adverse events (AEs) and cortisol <150 nmol/l at week 4. RESULTS: DAI response rates at week 4 were 64.6% and 66.2% with BDP and PD, respectively, demonstrating non-inferiority of BDP vs. PD (delta: -1.56; 95% confidence interval (CI) -13.00-9.88, P=0.78). Patients with steroid-related AEs and cortisol <150 nmol/l at week 4 were 38.7% in the BDP group and 46.9% in the PD group (P=0.17 between groups). No safety signals were observed in both the groups. CONCLUSIONS: BDP was non-inferior to PD in the treatment of active UC, with a good safety profile in both the groups.

Value of multidetector computed tomography angiography in severe non-variceal upper gastrointestinal bleeding: a retrospective study in a referral bleeding unit.

BACKGROUND: Non-variceal upper gastrointestinal bleeding is a common gastroenterological emergency associated with significant morbidity and mortality. Upper gastrointestinal endoscopy is currently recommended as the gold standard modality for both diagnosis and treatment. As historically played a limited role in the diagnosis of acute non-variceal upper gastrointestinal bleeding, multidetector-row computed tomography angiography is emerging as a promising tool in the diagnosis of non-variceal upper gastrointestinal bleeding, especially for severe cases. However, to date, evidence concerning the role of multidetector-row computed tomography angiography in the non-variceal upper gastrointestinal bleeding diagnosis is still lacking. AIM: The purpose of this study was to retrospectively investigate the diagnostic performance of emergent multidetector-row computed tomography angiography performed prior to any diagnostic modality or following urgent upper endoscopy to identify the status, the site, and the underlying etiology of severe non-variceal upper gastrointestinal bleeding. METHODS: Institutional databases were reviewed in order to identify severe acute non-variceal upper gastrointestinal bleeding patients who were admitted to our bleeding unit and were referred for emergent multidetector-row computed tomography angiography prior to any hemostatic treatment (< 3 h) or following (< 3 h) endoscopy, between December 2019 and October 2022. The study aim was to evaluate the diagnostic performance of multidetector-row computed tomography angiography to detect the status, the site, and the etiology of severe non-variceal upper gastrointestinal bleeding with endoscopy, digital subtraction angiography, surgery, pathology, or a combination of them as reference standards. RESULTS: A total of 68 patients (38 men, median age 69 years [range 25-96]) were enrolled. The overall multidetector-row computed tomography angiography sensitivity, specificity, and accuracy to diagnose bleeding status were 77.8% (95% CI: 65.5-87.3), 40% (95% CI: 5.3-85.3), and 75% (95% CI: 63.0-84.7), respectively. Finally, the overall multidetector-row computed tomography angiography sensitivity to identify the bleeding site and the bleeding etiology were 92.4% (95% CI: 83.2-97.5) and 79% (95% CI: 66.8-88.3), respectively. CONCLUSION: Although esophagogastroduodenoscopy is the mainstay in the diagnosis and treatment of most non-variceal upper gastrointestinal bleeding cases, multidetector-row computed tomography angiography seems to be a feasible and effective modality in detecting the site, the status, and the etiology of severe acute non-variceal upper gastrointestinal bleeding. It may play a crucial role in the management of selected cases of non-variceal upper gastrointestinal bleeding, especially those clinically severe and/or secondary to rare and extraordinary rare sources, effectively guiding timing and type of treatment. However, further large prospective studies are needed to clarify the role of multidetector-row computed tomography angiography in the diagnostic process of acute non-variceal upper gastrointestinal bleeding.

Risk of malignant arrhythmias in initially symptomatic patients with Wolff-Parkinson-White syndrome: results of a prospective long-term electrophysiological follow-up study.

BACKGROUND: The available amount of detailed long-term data in patients with Wolff-Parkinson-White syndrome is limited, and no prospective electrophysiological studies looking at predictors of malignant arrhythmia are available. METHODS AND RESULTS: Among 8575 symptomatic Wolff-Parkinson-White patients with atrioventricular reentrant tachycardia referred for electrophysiological test, 369 (mean age, 23±12.5 years) declined catheter ablation and were followed up. The primary end point of the study was to evaluate over a 5-year follow-up the predictors and characteristics of patients who develop malignant arrhythmias. After a mean follow-up of 42.1±10 months, malignant arrhythmias developed in 29 patients (mean age, 13.9±5.6 years; 26 male), resulting in presyncope/syncope (25 patients), hemodynamic collapse (3 patients), or cardiac arrest caused by ventricular fibrillation (1 patient). Of the remaining 340 patients, 168 (mean age, 34.2±9.0 years) remained asymptomatic up to 5 years, and 172 (mean age, 13.6±5.1 years) had benign recurrence, including sustained atrioventricular reentrant tachycardia (132 patients) or atrial fibrillation (40 patients). Compared with the group with no malignant arrhythmias, the group with malignant arrhythmias showed shorter accessory-pathway effective refractory period (P<0.001) and more often exhibited multiple accessory pathways (P<0.001), and atrioventricular reentrant tachycardia triggering sustained pre-excited atrial fibrillation was more frequently inducible (P<0.001). Multivariable analysis demonstrated that short accessory-pathway effective refractory period (P<0.001) and atrioventricular reentrant tachycardia triggering sustained pre-excited atrial fibrillation (P<0.001) were independent predictors of malignant arrhythmias. CONCLUSIONS: Symptomatic patients with Wolff-Parkinson-White syndrome generally have a good outcome, and predictors of malignant arrhythmias are similar to those reported for asymptomatic patients with ventricular pre-excitation.

Enteropathic spondyloarthritis: from diagnosis to treatment.

Enteropathic arthritis (EA) is a spondyloarthritis (SpA) which occurs in patients with inflammatory bowel diseases (IBDs) and other gastrointestinal diseases. Diagnosis is generally established on the medical history and physical examination. It was, generally, made according to the European Spondyloarthropathy Study Group (ESSG) criteria. Rheumatic manifestations are the most frequent extraintestinal findings of IBD with a prevalence between 17% and 39%, and IBD is associated, less frequently, with other rheumatic disease such as rheumatoid arthritis, Sjogren syndrome, Takayasu arteritis, and fibromyalgia. Although the pathogenesis of EA has not been plainly clarified, the most popular theory supposes that joint inflammation occurs in genetically predisposed subjects with bacterial gut infections, provided an important evidence for a possible relationship between inflammation of the gut mucosa and arthritis. The management of patients with EA requires an active cooperation between the gastroenterologist and rheumatologist.

The effectiveness of current acute variceal bleed treatments in unselected cirrhotic patients: refining short-term prognosis and risk factors.

OBJECTIVES: The mortality from esophageal variceal hemorrhage in liver cirrhosis patients remains approximately 15-20%. Predictors of short-term outcomes, such as the hepatic venous pressure gradient, are often unavailable in the acute setting. Clinical variables seem to have a similar predictive performance, but some variables including active bleeding during endoscopy have not been reevaluated after the utilization of endoscopic banding as endoscopic procedure. In addition, patients with severe liver failure are often excluded from clinical trials. The aim of this study was to prospectively reevaluate the risk factors affecting a 5-day failure after acute variceal bleeding in unselected cirrhotic patients, managed with the current standard treatment using vasoactive drugs, band ligation, and antibiotics. METHODS: One hundred and eighty five patients with liver cirrhosis and variceal bleeding admitted from January 2010 to July 2011 were evaluated. RESULTS: Hepatocellular carcinoma was present in 28.1% of cases and portal vein thrombosis (PVT) was present in 17.3% of cases. Band ligation was feasible in 92.4% of cases. Five-day failure occurred in 16.8% of cases; 12 patients (6.5%) experienced failure to control bleeding or early rebleeding, and 66.7% of patients died within 5 days. The overall 5-day mortality rate was 14.6%. By multivariate analysis, we determined that Child-Pugh class C, a white blood cell count over 10 × 10(9)/l, and the presence of PVT were the only independent predictors of the 5-day failure. CONCLUSIONS: The prognosis of a consistent group of liver cirrhosis patients with variceal bleeding remains poor. The current treatment is highly effective in controlling variceal bleeding, but mortality is related mainly to the severity of liver failure.

Hypoxic hepatitis occurring in cirrhosis after variceal bleeding: still a lethal disease.

BACKGROUND: Hypoxic hepatitis (HH) occurring after gastrointestinal bleeding in cirrhotic patients has been scarcely studied and is reported as a rare occurrence carrying a severe prognosis. The management of bleeding from esophageal varices (BEV) and similarly the prognosis has improved in the last decades. GOALS: To evaluate retrospectively the incidence, clinical features, risk factors, and outcome of HH occurring in cirrhotic patients with BEV treated with the current standard therapy. Cirrhotics with BEV consecutively admitted from 2004 to 2008 were considered. Standard therapy consisted of intensive care support, somatostatin, antibiotics, and band ligation. HH was diagnosed if an elevation of alanine aminotransferase >10-fold from basal occurred. RESULTS: Among 349 patients admitted for BEV, 24 (6.8%) had HH. Most patients were over 60 years old and had advanced liver disease; 41.7% had hepatocellular carcinoma, and 29.2% had portal vein thrombosis (PVT). Hypovolemic shock occurred in 16 (66.7%) patients, and failure to control initial bleeding in 12 (50%) patients. The 6-week mortality rate was 83.3% in HH compared with 24.6% in non-HH patients. Causes of death were massive bleeding in 4, hepatic encephalopathy in 7, and renal failure in 9. Binary logistic regression analysis showed that failure to control initial bleeding, diabetes, and PVT were factors independently associated with the development of HH. CONCLUSIONS: HH occurring in cirrhosis with gastrointestinal bleeding still carries an ominous prognosis. The severity of hemorrhage as expressed by failure to control bleeding contributes heavily to HH; in addition, the presence of PVT and diabetes further compromising the hepatic circulatory reserve may favor hypoxic damage.

Assessment of surgeon communication skills from the patient perspective: A national evaluation using the Communication Assessment Tool.

OBJECTIVE: The Communication Assessment Tool (CAT) has previously been translated and adapted to the Italian context. This national study aimed to validate the CAT and evaluate communication skills of practicing surgeons from the patient perspective. METHODS: CAT consists of 14 items associated with a 5-point scale (5 = excellent); results are reported as the percent of ''excellent'' scores. It was administered to 920 consenting outpatients aged 18-84 in 26 Italian surgical departments. RESULTS: The largest age group was 45-64 (43.8%); 52.2% of the sample was male. Scores ranged from 44.6% to 66.6% excellent. The highest-scoring items were "Treated me with respect" (66.6%), "Gave me as much information as I wanted" (66.3%) and "Talked in terms I could understand" (66.0%); the lowest was "Encouraged me to ask questions" (44.6%). Significant differences were associated with age (18-24 year old patients exhibited the lowest scores) and geographical location (Northern Italy had the highest scores). CONCLUSION: CAT is a valid tool for measuring communication in surgical settings. PRACTICE IMPLICATIONS: Results suggest that expectations of young people for communication in surgical settings are not being met. While there is room to improve communication skills of surgeons across Italy, patients highlighted the greatest need in the Central and Southern regions.

Effectiveness and safety of vedolizumab in a matched cohort of elderly and nonelderly patients with inflammatory bowel disease: the IG-IBD LIVE study.

BACKGROUND: Vedolizumab registration trials were the first to include elderly patients with moderate-to-severe ulcerative colitis (UC) or Crohn's disease (CD), but few real-life data have been reported in this population. AIMS: We investigated the effectiveness and safety of vedolizumab in matched cohorts of elderly and nonelderly UC and CD patients. METHODS: The Long-term Italian Vedolizumab Effectiveness (LIVE) study is a retrospective-prospective study including UC and CD patients who started vedolizumab from April 2016 to June 2017. Elderly patients (≥65 years) were matched clinically 1:2 to nonelderly patients (18-64 years); the 2 groups were followed until drug discontinuation or June 2019. RESULTS: The study included 198 elderly (108 UC, 90 CD) and 396 matched nonelderly patients (205 UC, 191 CD). Nonelderly UC patients had a significantly higher persistence on vedolizumab compared to elderly patients (67.6% vs. 51.4%, p = 0.02). No significant difference in effectiveness was observed between elderly and nonelderly CD patients (59.4% vs. 52.4%, p = 0.32). Age ≥65 years was associated with lower persistence in UC; for CD, previous exposure to anti-TNF-α agents, Charlson comorbidity index >2 and moderate-to-severe clinical activity at baseline were associated with lower persistence. There were recorded 130 adverse events, with comparable rates between the two groups. A Charlson comorbidity index >2 was associated with an increased risk of adverse events. CONCLUSION: Vedolizumab can be considered a safe option in elderly IBD patients. Its effectiveness in elderly UC patients may be reduced, while no age-dependent effect on effectiveness was observed in CD.

Serum calprotectin: an antimicrobial peptide as a new marker for the diagnosis of sepsis in very low birth weight newborns.

To determine the diagnostic utility of serum calprotectin, a mediator of innate immune response against infections, we performed a multicenter study involving newborns with a birth weight < 1500 g and a postnatal age >72 hours of life. The diagnostic accuracy of serum calprotectin was compared with that of the most commonly used markers of neonatal sepsis (white blood cell count, immature-to-total-neutrophil ratio, platelet count, and C-reactive protein). We found that the serum calprotectin concentration was significantly higher (P < .001) in 62 newborns with confirmed sepsis (3.1 ± 1.0 µg/mL) than in either 29 noninfected subjects (1.1 ± 0.3 µg/ml) or 110 healthy controls (0.91 ± 0.58 µg/ml). The diagnostic accuracy of serum calprotectin was greater (sensitivity 89%, specificity 96%) than that of the traditional markers of sepsis. In conclusion, serum calprotectin is an accurate marker of sepsis in very low birth weight newborns.

Long term remission after ileorectal anastomosis in Crohn's colitis.

BACKGROUND: Crohn's disease represents a heterogeneous entity, but its location tends to be relatively stable overtime. For extensive refractory Crohn's colitis, ileorectal anastomosis after colectomy is an engaging option, since the necessity of a permanent ileostomy is avoided. AIMS: In our study, the long-term outcome of two groups of patients with Crohn's colitis who underwent colectomy and ileorectal anastomosis was compared. The first group had isolated colonic Crohn's disease without rectal involvement and perianal disease, while the second group included patients who had rectal and/or ileal involvement, with or without perianal disease. METHODS: Between 1996 and 2016, in a single IBD tertiary center, 80 patients with a history of colectomy and ileorectal anastomosis for refractory Crohn's colitis were retrospectively identified. RESULTS: Recurrence of disease was diagnosed in 57/64 of patients with Crohn's colitis with rectal and/or ileal and/or perianal involvement compared with 1/16 of patients with isolated Crohn's colitis without rectal and perianal disease in a median time of recurrence of 2 years (IQR 1-6 years, minimum to maximum, 1-18 years, p < 0.001). Only 6 patients (7,5%) underwent definitive end ileostomy without proctectomy (1 in the noIRP group and 5 in the IRP group). CONCLUSION: Our data suggest that colectomy with ileorectal anastomosis may represent a curative option in patients with refractory isolated colitis without rectal and perianal involvement.
