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.

Ustekinumab (UST), a human anti-IL12/23p40 monoclonal antibody, was approved by FDA and EMA for the treatment of moderate to severe Crohn's disease (CD). Whether UST is effective in inducing deep remission, including mucosal healing and transmural healing, in patients with CD in a real life setting is not completely clear. This study was performed on 92 subjects with confirmed diagnosis of moderate to severe Crohn's disease and no neoplasia. Before inclusion, all patients had been exposed and had failed to respond to conventional and/or at least one biological therapy. All patients underwent endoscopic examination and bowel MRI and ultrasonography at baseline (T0). At week 52 (T52), patients underwent colonoscopy for assessment of mucosal healing and MRI or ultrasonography for assessment of transmural healing. CDAI was used for the assessment of clinical response and clinical remission. SES-CD was used to assess endoscopic response and remission. Incidence of treatment-related adverse events (TRAEs) was recorded during the study period. Clinical response at week 52 was achieved in 38 (50.5%) patients and clinical remission in 29 (39%). Twenty-six (34%) patients showed mucosal healing, 34 (45%) showed partial endoscopic response. We observed a reduction in SES-CD of at least 50% in 34 (45%) patients as well as an SES-CD ≤ 2 in 26 (35%) patients. All patients with mucosal healing also showed transmural healing. No major TRAEs were observed during treatment. In this multicenter, real life study, we show that UST was well tolerated and effective in inducing clinical response and clinical remission in patients with moderate to severe CD who had previously failed to respond to conventional or biologic therapy. UST showed limited efficacy in inducing deep remission (i.e. mucosal+transmural healing).

Purpose Ischemic Colitis (IC) can be transient or it can have evolving presentations that have a profound impact on outcome. Based on a chart review of cases, the aim of the study was to characterize the prevailing histological features of IC and to determine to what extent the severity of necrosis affected outcomes.Methods: We conducted a retrospective study of patients with IC who were referred to our department of surgery from 2013 to 2016. Moreover, the relationships among IC presentations, comorbidities and surgical procedures were surveyed. The severity of necrosis was investigated as the main histological feature, and a morphological criterion was used to grade necrosis from mild to severe differences between groups were determined with a univariate analysis, variables predicting death with a multivariate analysis and a flow-chart identifying clinical behavior.Results: Among 82 patients with an IC diagnosis, 74 (90.3%) were referred for surgical consultation, and 8 (9.7%) patients were not because they had fulminant IC. Comorbidities affected 53 (71.6%) patients. Ten (13.5%) patients underwent surgery, all of whom had severe necrosis, and 6 (60%) died perioperatively. The severity of necrosis impacted whether surgery was performed for evolving forms of IC (OR: 9.4, 95% CI: 1.8-48.8, p=0.002), the number of patients who had died by follow-up (OR: 0.2, 95% CI: 0.08 to 0.7, p=0.013), and the frequency of right-sided IC (χ-square 12.4, p=0.029); however, necrosis severity was not affected by the presence of comorbidities (OR: 2.2, 95% CI: 0.724 to 7.124, p=0.154). Advanced age (OR: 1.119, 95% CI 1.015 to 1.234, P=0.023) and need of surgery predicted death (OR: 5.597, 95% CI 1.125 to 27.842, P=0.035). Conclusion: This study quantified to what extent the severity of histological findings affected poor outcomes and what factors predicted death. These findings allowed us to suggest prophylactic therapies for transient form of IC.

Objectives We performed a systematic review and meta-analysis of all the available evidence to assess the efficacy and safety of paracetamol for the treatment of patent ductus arteriosus (PDA) in neonates, and to explore the effects of clinical variables on the risk of closure. Data source MEDLINE, Scopus and ISI Web of Knowledge databases, using the following medical subject headings and terms: paracetamol, acetaminophen and patent ductus arteriosus. Electronic and manual screening of conference abstracts from international meetings of relevant organisations. Manual search of the reference lists of all eligible articles. Study selection Studies comparing paracetamol versus ibuprofen, indomethacin, placebo or no intervention for the treatment of PDA. Data extraction Data regarding efficacy and safety were collected and analysed. Results Sixteen studies were included: 2 randomised controlled trials (RCTs) and 14 uncontrolled studies. Quality of selected studies is poor. A meta-analysis of RCTs does not demonstrate any difference in the risk of ductal closure (Mantel-Haenszel model, RR 1.07, 95% CI 0.87 to 1.33 and RR 1.03, 95% CI 0.92 to 1.16, after 3 and 6 days of treatment, respectively). Proportion meta-analysis of uncontrolled studies demonstrates a pooled ductal closure rate of 49% (95% CI 29% to 69%) and 76% (95% CI 61% to 88%) after 3 and 6 days of treatment with paracetamol, respectively. Safety profiles of paracetamol and ibuprofen are similar. Conclusions Efficacy and safety of paracetamol appear to be comparable with those of ibuprofen. These results should be interpreted with caution, taking into account the non-optimal quality of the studies analysed and the limited number of neonates treated with paracetamol so far.

Background And Objective:Gastric acidity is a major nonimmune defense mechanism against infections. The objective of this study was to investigate whether ranitidine treatment in very low birth weight (VLBW) infants is associated with an increased risk of infections, necrotizing enterocolitis (NEC), and fatal outcome.Methods:Newborns with birth weight between 401 and 1500 g or gestational age between 24 and 32 weeks, consecutively observed in neonatal intensive care units, were enrolled in a multicenter prospective observational study. The rates of infectious diseases, NEC, and death in enrolled subjects exposed or not to ranitidine were recorded.Results:We evaluated 274 VLBW infants: 91 had taken ranitidine and 183 had not. The main clinical and demographic characteristics did not differ between the 2 groups. Thirty-four (37.4%) of the 91 children exposed to ranitidine and 18 (9.8%) of the 183 not exposed to ranitidine had contracted infections (odds ratio 5.5, 95% confidence interval 2.9–10.4, P < .001). The risk of NEC was 6.6-fold higher in ranitidine-treated VLBW infants (95% confidence interval 1.7–25.0, P = .003) than in control subjects. Mortality rate was significantly higher in newborns receiving ranitidine (9.9% vs 1.6%, P = .003).Conclusions:Ranitidine therapy is associated with an increased risk of infections, NEC, and fatal outcome in VLBW infants. Caution is advocated in the use of this drug in neonatal age.

The clinical usefulness of an immunotest was evaluated by using purified poly(adenosine diphosphate (ADP)-ribose) polymerase from Sulfolobus solfataricus (PARPSso) as an antigen to detect the presence of abnormal anti-PARP antibodies in the sera of patients with systemic lupus erythematosus (SLE) at different clinical stages. Sera from 44 patients with SLE, subgrouped on the basis of disease activity (16 with inactive disease, 28 with active disease) were analysed with a new immunotest to detect anti-PARP antibodies, and with an immunofluorescent (IIF) assay for antinuclear antibodies (ANA) detection. ANA detection by IIF revealed that sera of healthy subjects were negative, whereas sera from patients with SLE were positive in all cases (13 positive at 1:80, 15 at 1:160, 15 at 1:320, 1 at 1:640, v/v). Anti-PARP activity was higher in ANApositive patients than in controls (p = 0.005). Within the group of SLE sera, disease and anti-PARP activity was increased more significantly in patients with active than in those with inactive disease (p < 0.001 and p = 0.001, respectively). Correlation between anti-PARP and disease activity in SLE patients was statistically significant (p < 0.001). PARPSso seems to be suitable for detecting anti-PARP antibodies and could play a role as a serological marker of disease activity in patients with SLE.
