RESUMO
OBJECTIVE: Antireflux surgery can be proposed in patients with GORD, especially when proton pump inhibitor (PPI) use leads to incomplete symptom improvement. However, to date, international consensus guidelines on the clinical criteria and additional technical examinations used in patient selection for antireflux surgery are lacking. We aimed at generating key recommendations in the selection of patients for antireflux surgery. DESIGN: We included 35 international experts (gastroenterologists, surgeons and physiologists) in a Delphi process and developed 37 statements that were revised by the Consensus Group, to start the Delphi process. Three voting rounds followed where each statement was presented with the evidence summary. The panel indicated the degree of agreement for the statement. When 80% of the Consensus Group agreed (A+/A) with a statement, this was defined as consensus. All votes were mutually anonymous. RESULTS: Patients with heartburn with a satisfactory response to PPIs, patients with a hiatal hernia (HH), patients with oesophagitis Los Angeles (LA) grade B or higher and patients with Barrett's oesophagus are good candidates for antireflux surgery. An endoscopy prior to antireflux surgery is mandatory and a barium swallow should be performed in patients with suspicion of a HH or short oesophagus. Oesophageal manometry is mandatory to rule out major motility disorders. Finally, oesophageal pH (±impedance) monitoring of PPI is mandatory to select patients for antireflux surgery, if endoscopy is negative for unequivocal reflux oesophagitis. CONCLUSION: With the ICARUS guidelines, we generated key recommendations for selection of patients for antireflux surgery.

BACKGROUND AND AIMS: Empirical dose intensification and therapeutic drug monitoring [TDM] of infliximab [IFX] trough levels [ITLs] and antibody to infliximab [ATI] assays are recognized approaches for managing loss of response [LoR] in patients with inflammatory bowel disease [IBD]. The aim of the study was to compare these two interventions in a clinical setting, in terms of effectiveness and cost savings. METHODS: Consecutive IBD patients experiencing LoR were clinically managed according to a TDM algorithm. A historical group of empirically treated patients, for whom sera for ITLs and ATI assays had been collected, served as the control group. Clinical outcomes 12 weeks after the therapeutic interventions were compared between the two groups. A cost-minimization analysis was performed to compare the economic impact of these two approaches. RESULTS: Ninety-six patients were enrolled prospectively and compared with 52 controls. The two cohorts were similar in characteristics and in the distribution of TDM results. In the prospective cohort, however, we observed less IFX dose escalations compared with in the controls [45% versus 71%, p = 0.003]. Also, more patients were switched to a different anti-TNFα in the prospective cohort than in the control cohort [25% versus 4%, p = 0.001]. The percentages of patients achieving a clinical response at 12 weeks were 52% and 54% for the prospective and control groups, respectively. By cost analysis, we estimated a savings of 15% if the TDM algorithm was applied. CONCLUSIONS: In our population, applying a TDM algorithm for LoR to IFX resulted in less dose escalations, without loss of efficacy, compared with empirical adjustment. In addition, the TDM approach was cost-effective.

BACKGROUND: Altered body composition is frequently observed in Crohn's disease (CD) patients. AIMS: To investigate the nutritional status, and the effect of different therapeutic regimes in adult CD patients. METHODS: Fat free mass (FFM) and BIA-derived phase angle (PhA) were assessed in 45 CD patients, 22 on conventional therapy (CT) and 23 on maintenance therapy with infliximab (MT). Nutritional status was also assessed in 12 CD patients before and following the induction protocol with infliximab. BIA data of CD patients were compared with those of 20 healthy asymptomatic volunteers. In CD patients C Reactive Protein (CRP) and albuminaemia dosage were obtained. RESULTS: The mean values of PhA and of FFM were significantly lower in CT patients when compared with control group and MT patients. Following infliximab treatment FFM increased, although not significantly, while mean phase angle value significantly increased from 4.6±0.3 to 6.2±0.4 (p<0.05). CRP was significantly lower in MT patients compared to that in CT patients. CONCLUSION: CD patients on conventional therapy showed a lower FFM and a lower mean phase angle score compared to those on infliximab therapy. Following infliximab treatment the mean phase angle score normalized. PhA is a reliable nutritional indicator in IBD patients and could be considered as an additional tool for assessing response to treatment.
