RESUMO
Background and Aim: Combining proton pump inhibitors (PPIs) with prokinetics can provide synergistic action in patients with gastroesophageal reflux disease (GERD) and overlapping dyspepsia, but data regarding this is lacking. Methods: This single-center, prospective study evaluated the efficacy and safety of 6-week treatment with fixed-drug combination (FDC) of pantoprazole (PPI) and itopride (prokinetic) in 50 patients with ≥3 month history of GERD and overlapping dyspepsia refractory to pantoprazole. Efficacy was assessed as reduction in GERD symptom assessment scale (GSAS) distress score for 15 symptoms from baseline to week 6. Adverse events (AEs) were monitored up to week 6. Results: Although heartburn was the most common symptom at week 6 (26.8%), its frequency significantly decreased from baseline (84.0%; P <0.01). A similar trend was observed for other symptoms: pressure/discomfort inside chest (19.5%), belching (14.6%), regurgitation (12.2%), bloating (9.8%), flatulence (9.8%), early satiety (7.3%), acidic/sour taste in mouth (7.3%), nausea (7.3%), frequent gurgling in stomach/belly (4.9%), and pressure/lump in throat (2.4%). Mean distress scores of all symptoms markedly decreased at week 6. Three AEs (n = 2) of moderate intensity were reported. Conclusion: The FDC of pantoprazole and itopride showed favorable efficacy and safety in patients with GERD and overlapping dyspepsia refractory to pantoprazole monotherapy. Nevertheless, further studies are warranted.
RESUMO
BACKGROUND: Although the preferred management approach for patients with infected necrotising pancreatitis is endoscopic transluminal stenting followed by endoscopic necrosectomy as step-up treatment if there is no clinical improvement, the optimal timing of necrosectomy is unclear. Therefore, we aimed to compare outcomes between performing upfront necrosectomy at the index intervention versus as a step-up measure in patients with infected necrotising pancreatitis. METHODS: This single-blinded, multicentre, randomised trial (DESTIN) was done at six tertiary care hospitals (five hospitals in the USA and one hospital in India). We enrolled patients (aged ≥18 years) with confirmed or suspected infected necrotising pancreatitis with a necrosis extent of at least 33% who were amenable to endoscopic ultrasound-guided drainage. By use of computer-generated permuted block randomisation (block size four), eligible patients were randomly assigned (1:1) to receive either upfront endoscopic necrosectomy or endoscopic step-up treatment. Endoscopists were not masked to treatment allocation, but participants, research coordinators, and the statistician were. Lumen-apposing metal stents (20 mm diameter; 10 mm saddle length) were used for drainage in both groups. In the upfront group, direct necrosectomy was performed immediately after stenting in the same treatment session. In the step-up group, direct necrosectomy or additional drainage was done at a subsequent treatment session if there was no clinical improvement (resolution of any criteria of systemic inflammatory response syndrome or sepsis or one or more organ failure and at least a 25% percentage decrease in necrotic collection size) 72 h after stenting. The primary outcome was the number of reinterventions per patient to achieve treatment success from index intervention to 6 months' follow-up, which was defined as symptom relief in conjunction with disease resolution on CT. Reinterventions included any endoscopic or radiological procedures performed for necrosectomy or additional drainage after the index intervention, excluding the follow-up procedure at 4 weeks for stent removal. All endpoints and safety were analysed by intention-to-treat. This study is registered with ClinicalTrials.gov, NCT05043415 and NCT04113499, and recruitment and follow-up have been completed. FINDINGS: Between Nov 27, 2019, and Oct 26, 2022, 183 patients were assessed for eligibility and 70 patients (24 [34%] women and 46 [66%] men) were randomly assigned to receive upfront necrosectomy (n=37) or step-up treatment (n=33) and included in the intention-to-treat population. At the time of index intervention, seven (10%) of 70 patients had organ failure and 64 (91%) patients had walled-off necrosis. The median number of reinterventions was significantly lower for upfront necrosectomy (1 [IQR 0 to 1] than for the step-up approach (2 [1 to 4], difference -1 [95% CI -2 to 0]; p=0·0027). Mortality did not differ between groups (zero patients in the upfront necrosectomy group vs two [6%] in the step-up group, difference -6·1 percentage points [95% CI -16·5 to 4·5]; p=0·22), nor did overall disease-related adverse events (12 [32%] patients in the upfront necrosectomy group vs 16 [48%] patients in the step-up group, difference -16·1 percentage points [-37·4 to 7·0]; p=0·17), nor procedure-related adverse events (four [11%] patients in the upfront necrosectomy group vs eight [24%] patients in the step-up group, difference -13·4 percentage points [-30·8 to 5·0]; p=0·14). INTERPRETATION: In stabilised patients with infected necrotising pancreatitis and fully encapsulated collections, an approach incorporating upfront necrosectomy at the index intervention rather than as a step-up measure could safely reduce the number of reinterventions required to achieve treatment success. FUNDING: None.
