RESUMO
BACKGROUND: Helicobacter pylori (H. pylori) is the most common chronic bacterial infection. Its management has to rely on local effectiveness, given the geographical variability of bacterial antibiotic resistance. We evaluated treatment effectiveness in naïve patients in Greece, as part of the European Registry on the management of H. pylori (Hp-EuReg). METHODS: Patients were registered in the AEG-REDCap Electronic Case Report Form from 2013-2020. All cases with a first-line treatment were included. Modified intention-to-treat (mITT) analysis was used. RESULTS: A total of 547 patients from 5 medical institutions were treated with the following regimens: concomitant with proton pump inhibitors (PPIs), clarithromycin, amoxicillin and metronidazole (concomitant-C+A+M) (38%); hybrid with PPI, clarithromycin, amoxicillin and metronidazole (hybrid-C+A+M) (20%); sequential with PPI, clarithromycin, amoxicillin and tinidazole (sequential-C+A+T) (12%); sequential with PPI, clarithromycin, amoxicillin and metronidazole (sequential-C+A+M) (12%); concomitant with PPI, clarithromycin, amoxicillin and tinidazole (concomitant-C+A+T) (8%); triple with PPI, clarithromycin and amoxicillin (triple-C+A) (7%); and other (3%). Overall compliance was 99%. Triple-C+A, sequential-C+A+T, sequential-C+A+M and concomitant-C+A+T were used from 2013-2015. The respective mITT cure rates (95% confidence interval) were 92% (78-98), 87% (76-94), 67% (54-78) and 91% (79-98). Since 2015, patients were also treated with concomitant-C+A+M and hybrid-C+A+M regimens, with respective mITT cure rates of 90% (85-94) and 88% (80.5-94). Adverse events were reported by 31% of the patients, dysgeusia being the most frequent (15%). CONCLUSIONS: "Optimized" H. pylori therapies should achieve cure rates over 90%. In Greece, at present, only non-bismuth quadruple concomitant regimens achieve this target and can be recommended as first-line treatment.
RESUMO
Background: Bacterial antibiotic resistance changes over time depending on multiple factors; therefore, it is essential to monitor the susceptibility trends to reduce the resistance impact on the effectiveness of various treatments. Objective: To conduct a time-trend analysis of Helicobacter pylori resistance to antibiotics in Europe. Methods: The international prospective European Registry on Helicobacter pylori Management (Hp-EuReg) collected data on all infected adult patients diagnosed with culture and antimicrobial susceptibility testing positive results that were registered at AEG-REDCap e-CRF until December 2020. Results: Overall, 41,562 patients were included in the Hp-EuReg. Culture and antimicrobial susceptibility testing were performed on gastric biopsies of 3974 (9.5%) patients, of whom 2852 (7%) were naive cases included for analysis. The number of positive cultures decreased by 35% from the period 2013-2016 to 2017-2020. Concerning naïve patients, no antibiotic resistance was found in 48% of the cases. The most frequent resistances were reported against metronidazole (30%), clarithromycin (25%), and levofloxacin (20%), whereas resistances to tetracycline and amoxicillin were below 1%. Dual and triple resistances were found in 13% and 6% of the cases, respectively. A decrease (p < 0.001) in the metronidazole resistance rate was observed between the 2013-2016 (33%) and 2017-2020 (24%) periods. Conclusion: Culture and antimicrobial susceptibility testing for Helicobacter pylori are scarcely performed (<10%) in Europe. In naïve patients, Helicobacter pylori resistance to clarithromycin remained above 15% throughout the period 2013-2020 and resistance to levofloxacin, as well as dual or triple resistances, were high. A progressive decrease in metronidazole resistance was observed.
RESUMO
The incidence of acute pancreatitis (AP) is increasing. AP is one of the gastrointestinal diseases that most frequently requires hospital admission in affected individuals. In the last few years, considerable scientific evidence has led to substantial changes in the medical and surgical treatment of this disease. New knowledge of the physiopathology of AP indicates that its severity is influenced by its systemic effects (organ failure), especially if the disease is persistent, and also by local complications (fluid collections or necrosis), especially if these become infected. Treatment should be personalized and depends on the patient's clinical status, the location of the necrosis, and disease stage.
