Role of compliance in Helicobacter pylori eradication treatment: Results of the European Registry on H. pylori management.

BACKGROUND: Adherence to Helicobacter pylori (H. pylori) eradication treatment is a cornerstone for achieving adequate treatment efficacy. OBJECTIVE: To determine which factors influence compliance with treatment. METHODS: A systematic prospective non-interventional registry (Hp-EuReg) of the clinical practice of European gastroenterologists. Compliance was considered adequate if ≥90% drug intake. Data were collected until September 2021 using the AEG-REDCap e-CRF and were subjected to quality control. Modified intention-to-treat analyses were performed. Multivariate analysis carried out the factors associated with the effectiveness of treatment and compliance. RESULTS: Compliance was inadequate in 646 (1.7%) of 38,698 patients. The non-compliance rate was higher in patients prescribed longer regimens (10-, 14-days) and rescue treatments, patients with uninvestigated dyspepsia/functional dyspepsia, and patients reporting adverse effects. Prevalence of non-adherence was lower for first-line treatment than for rescue treatment (1.5% vs. 2.2%; p < 0.001). Differences in non-adherence in the three most frequent first-line treatments were shown: 1.1% with proton pump inhibitor + clarithromycin + amoxicillin; 2.3% with proton pump inhibitor clarithromycin amoxicillin metronidazole; and 1.8% with bismuth quadruple therapy. These treatments were significantly more effective in compliant than in non-compliant patients: 86% versus 44%, 90% versus 71%, and 93% versus 64%, respectively (p < 0.001). In the multivariate analysis, the variable most significantly associated with higher effectiveness was adequate compliance (odds ratio, 6.3 [95%CI, 5.2-7.7]; p < 0.001). CONCLUSIONS: Compliance with Helicobacter pylori eradication treatment is very good. Factors associated with poor compliance include uninvestigated/functional dyspepsia, rescue-treatment, prolonged treatment regimens, the presence of adverse events, and the use of non-bismuth sequential and concomitant treatment. Adequate treatment compliance was the variable most closely associated with successful eradication.

Extensive colectomy in colorectal cancer and hereditary nonpolyposis colorectal cancer - long-term results / Colectomia extensa em cancro colorretal e cancro colorretal hereditário sem polipose - resultados a longo prazo

ABSTRACT Background: Colorectal cancer survival is better in hereditary nonpolyposis colorectal cancer patients than in sporadic colorectal cancer patients and even for hereditary nonpolyposis colorectal cancer with colorectal cancer is not consensual that extensive colectomy is preferable to partial colectomy. This study analyzes and compares the long-term results of these two groups of patients submitted to curative subtotal colectomy or total colectomy. Methods: Between 2002 and 2018, 68 patients with colorectal cancer without familial adenomatous polyposis were submitted to a total or subtotal colectomy in a single tertiary center. The patients were divided in two groups: hereditary nonpolyposis colorectal cancer patients (with Amsterdam criteria) and sporadic colorectal cancer patients (the others). The presence of Amsterdam criteria for hereditary nonpolyposis colorectal cancer and germline mutation for mismatch repair genes was confirmed by clinical records. Results and survival were analyzed following surgery. Results: We obtained a sporadic colorectal cancer group with 31 patients and a hereditary nonpolyposis colorectal cancer group with 37 patients. The two groups differ in age but not in gender, tumor stage or surgical morbidity. The overall survival and disease-free survival were good in both groups but even better for hereditary nonpolyposis colorectal cancer group with statistical significance when comparing the two groups. Conclusion: Total or subtotal colectomy for colorectal cancer provides a good survival. These surgical procedures should be considered the first option for colorectal cancer in young hereditary non polyposis colorectal cancer patients. In those cases, they provide good long-term results, avoiding the risk of metachronous colorectal cancer and the surveillance is restricted only to the remaining need for rectum.

RESUMO Introdução: A sobrevivência do cancro colorretal é melhor em pacientes com cancro colorretal hereditário não associado a polipose do que em pacientes com cancro colorretal esporádico. Mesmo em casos de cancro colorretal hereditário sem polipose, a preferência pela colectomia total em relação à parcial não é consensual na literatura. Este estudo analisa e compara os resultados a longo prazo destes dois grupos de pacientes submetidos à colectomia curativa subtotal ou total. Métodos: Entre 2002 e 2018, 68 pacientes com cancro colorretal sem polipose adenomatosa familiar foram submetidos a colectomia total ou subtotal em um único centro terciário. Os pacientes foram divididos em dois grupos: aqueles com cancro colorretal hereditário sem polipose (de acordo com os critérios de Amsterdão) e os com cancro colorretal esporádico (os demais). Os critérios de Amsterdão para cancro colorretal hereditário sem polipose e a presença de mutação germinativa para os genes de reparação de ADN foram confirmados por consulta dos registros clínicos. Os resultados e a sobrevivência foram analisados após a cirurgia. Resultados: No presente estudo, 31 pacientes foram incluídos no grupo de cancro colorretal esporádico e 37 no grupo de cancro colorretal hereditário sem polipose. Diferenças significativas foram observadas em relação à idade, mas não ao gênero, estadio do tumor ou morbilidade cirúrgica. A sobrevivência global e a sobrevivência livre de doença foram boas em ambos os grupos, mas os resultados foram ainda melhores no grupo de cancro colorretal hereditário sem polipose, com significado estatístico. Conclusão: A colectomia total ou a colectomia subtotal para o cancro colorretal proporcionam uma boa sobrevivência e devem ser consideradas a primeira opção de tratamento em pacientes jovens com cancro colorretal hereditário sem polipose. Nestes pacientes, uma cirurgia cólica mais extensa permite a obtenção de bons resultados a longo prazo; reduz o risco de cancro colorretal metácrono e restringe a vigilância endoscópica ao reto remanescente.

Functional outcomes in patients submitted to restorative proctocolectomy with ileal pouch anal anastomosis in a single tertiary center / Resultados funcionais em pacientes submetidos a proctocolectomia restauradora com anastomose íleoanal e bolsa ileal em um centro terciário

ABSTRACT Background: Functional results after restorative proctocolectomy for ulcerative colitis and familial adenomatous polyposis are variable. We assessed functional results in patients with ileal pouch anal anastomosis and evaluated potential factors associated with poor functional results. Methods: Retrospective cohort study of 38 patients who were submitted to a restorative proctocolectomy with ileal pouch anal anastomosis, in the context of ulcerative colitis and familial adenomatous polyposis, in at tertiary referral center, in the period between 1993 and 2013. Clinical records were analyzed and telephone interviews with protocoled questionnaire to 32 patients (12 ulcerative colitis, 20 familial adenomatous polyposis) were performed. Pouch functional results were also evaluated based in the Oresland score. The functional results were analyzed at four points of the patient outcome. Results: In 25 patients were performed restorative proctocolectomy with ileal pouch anal anastomosis and in 7 patients total colectomy preceded protectomy with ileal pouch anal anastomosis. Protective ileostomy was performed in all patients. There was no mortality and post-operative complications related with the pouch was 12.5% but treated conservatively. The mean follow-up was 13.2 years. Pouch failure occurs in 9.4% (2 in familial adenomatous polyposis and 1 in ulcerative colitis). Familial adenomatous polyposis patients achieved the best outcome but the outcome was acceptable in both groups. The median Oresland score was good with small variations over the years, although the best score being reached at 5 years after the surgery. Conclusions: The long-term results in patients undergoing restorative proctocolectomy with ileal pouch anal anastomosis were good in both groups, although better in familial adenomatous polyposis. In both, the best score of functional results seems to be reached at 5 years after surgery.

RESUMO Introdução: Os resultados funcionais após proctocolectomia restauradora em casos de colite ulcerativa e polipose adenomatosa familiar são variáveis. Avaliamos os resultados funcionais em pacientes com anastomose ileoanal e bolsa ileal bem como os fatores potenciais associados a resultados funcionais fracos. Métodos: Estudo retrospectivo de coorte com 38 pacientes submetidos a proctocolectomia restauradora com anastomose ileoanal e bolsa ileal, no contexto de colite ulcerativa e polipose adenomatosa familiar, em um centro de referência terciário, no período entre 1993 e 2013. Analisamos os registos clínicos e realizamos entrevistas telefónicas com um questionário protocolado a 32 pacientes (12 colite ulcerativa, 20 polipose adenomatosa familiar). Também foram avaliados os resultados funcionais da bolsa, com base no escore de Oresland. Os resultados funcionais foram analisados em quatro pontos do desfecho de cada paciente. Resultados: Em 25 pacientes foi realizada proctocolectomia restauradora com anastomose ileoanal e bolsa ileal, e em 7 pacientes uma colectomia total precedeu a protectomia com anastomose ileoanal e bolsa ileal. Todos os pacientes foram submetidos a uma ileostomia protetora. Não ocorreram óbitos e as complicações pós-operatórias relacionadas com a bolsa chegaram a 12,5%, mas foram tratadas conservadoramente. O seguimento médio foi de 13,2 anos. Ocorreu defeito na bolsa em 9,4% (2 em polipose adenomatosa familiar e 1 em colite ulcerativa). Os pacientes com polipose adenomatosa familiar obtiveram o melhor resultado; contudo, em ambos os grupos o resultado foi considerado aceitável. A mediana do score de Oresland foi boa, tendo sido observadas pequenas variações ao longo dos anos, embora o melhor score tenha sido verificado 5 anos após a cirurgia. Conclusões: A longo prazo, os resultados para os pacientes submetidos a proctocolectomia restauradora com anastomose ileoanal e bolsa ileal foram bons em ambos os grupos, embora tenham sido considerados melhores nos pacientes com polipose adenomatosa familiar. Nos dois grupos, o melhor escore de resultados funcionais parece ser alcançado por volta dos 5 anos após a cirurgia.

Antiplatelet agents and/or anticoagulants are not associated with worse outcome following nonvariceal upper gastrointestinal bleeding

Background: Nonvariceal upper gastrointestinal bleeding emerges as a major complication of using antiplatelet agents and/or anticoagulants and represents a clinical challenge in patients undergoing these therapies. Aim: To characterize patients with nonvariceal upper gastrointestinal bleeding related to antithrombotics and their management, and to determine clinical predictors of adverse outcomes. Methods: Retrospective cohort of adults who underwent upper gastrointestinal endoscopy after nonvariceal upper gastrointestinal bleeding from 2010 to 2012. The outcomes were compared between patients exposed and not exposed to antithrombotics. Results: Five hundred and forty-eight patients with nonvariceal upper gastrointestinal bleeding (67% men; mean age 66.5 ± 16.4 years) were included, of which 43% received antithrombotics. Most patients had comorbidities. Peptic ulcer was the main diagnosis and endoscopic therapy was performed in 46% of cases. The 30-day mortality rate was 7.7% (n = 42), and 36% were bleeding-related. The recurrence rate was 9% and 14% of patients with initial endoscopic treatment needed endoscopic retreatment. There were no significant differences between the exposed and non-exposed groups in most outcomes. Co-morbidities, hemodynamic instability, high Rockall score, low hemoglobin (7.76 ± 2.72 g/dL) and higher international normalized ratio (1.63 ± 1.13) were associated significantly with mortality in a univariate analysis. Conclusions: Adverse outcomes were not associated with antithrombotic use. The management of nonvariceal upper gastrointestinal bleeding constitutes a challenge to clinical performance optimization and clinical cooperation (AU)

Double-balloon enteroscopy in the management of patients with Peutz-Jeghers syndrome: a retrospective cohort multicenter study / Enteroscopia de doble balón en el tratamiento de paciente con síndrome de Peutz-Jeghers: un estudio multicéntrico de cohorte retrospectiva

Background and objective: Little is known about the clinical impact of double-balloon enteroscopy (DBE) in patients with Peutz- Jeghers syndrome (PJS). The aim of this study was to assess the efficacy and safety of DBE in the management of small-bowel polyps in PJS patients. Patients and methods: We conducted a multicentre, retrospective cohort study, which included all consecutive patients diagnosed with PJS who underwent DBE for polypectomy between January 2006 and August 2012. In all cases, previous videocapsule enteroscopy had shown at least one polyp ≥ 10 mm in size. Results: Twenty-five patients (13 men; median age 36 years; 14 with prior laparotomy) underwent 46 DBE procedures (1 to 5 per patient, 44 via oral route). Polypectomy was performed in 39/46 DBEs. A total of 214 polyps were removed (median-size 30 mm), with a median number of polypectomies per procedure of 5.0 (range 1-18). The estimated maximum-sizes of resected polyps significantly decreased at each session: 30.0, 25.0, 20.0, 15.0, and 17.5 mm (p = 0.02). In 7 DBEs no polypectomy was performed (4-only minor polyps detected; 3-endoscopic irresecability). Complications occurred in 3/39 of therapeutic procedures (2-minor delayed bleeding; 1-mucosal tear), all of them dealt with conservative or endoscopic therapy. Six patients underwent elective surgery post DBE due to polyps not amenable for endoscopic resection. There were no small-bowel polyp related complications during a median follow-up of 56.5 months. Conclusion: DBE showed to be a safe and effective technique in the management of small-bowel polyps in PJS patients, allowing a presymptomatic and non-surgical approach (AU)
