RHEDAR study: Determination of the risk of gastrointestinal hemorrhage in treatment with dabigatran, acenocoumarol and rivaroxaban.

BACKGROUND AND AIM: Atrial fibrillation is a major cause of death and disability due to stroke. Vitamin K antagonist drugs are effective for prevention, but they have a narrow therapeutic range and multiple pharmacological interactions. In recent years, new therapeutic alternatives have been searched to minimize complications. The main objective is to evaluate the risk of gastrointestinal bleeding in anticoagulated patients and compare the classic treatment with new anticoagulants. METHODS: We conducted a retrospective cohort study to determine the risk of gastrointestinal bleeding in patients treated with acenocoumarol/dabigatran/rivaroxaban, between 2012 and 2016. We compared the classic with the new anticoagulant group, and a multivariate logistic regression analysis was used to determinate the risk factors of gastrointestinal bleeding. RESULTS: A total of 1213 patients were selected, 52.7% male patients, a mean age of 72.6 years old (± 14.563). 73.6% had atrial fibrilation. 14.5% of patients used acetylsalicylic acid, and 4% clopidogrel. 67.2% had a high-risk CHADS-2 Score, and 36.9% a high-risk HAS-BLED Score. We determined a 5.6% (68) of gastrointestinal bleeding, without differences according to anticoagulant used. The multivariate model showed a greater risk for digestive hemorrhage in patients with a previous hemorrhagic event (odds ratio [OR] = 2.422 95% confidence interval [CI]: 1.101-5.327) and the concomitant therapy with clopidogrel (OR = 2.373 95% CI: 0.996-5.652). CONCLUSIONS: No differences were found in the risk of gastrointestinal bleeding between the different anticoagulants. A previous gastrointestinal bleeding were considered independent risk factor. The HAS-BLED score should be taken into account to make clinical decisions about to prescribe anticoagulant treatment.

Análisis retrospectivo del uso de la cuádruple terapia con bismuto (Pylera(R)) en la práctica clínica real en España / Retrospective analysis of the use of quadruple therapy with bismuth (Pylera(R)) in real-life clinical practice in Spain

OBJETIVO: La resistencia de Helicobacter pylori a los antibióticos es un problema creciente en nuestro medio y es necesario mejorar las tasas de erradicación. La cuádruple terapia con bismuto se ha considerado el tratamiento de primera o segunda línea en el nuevo consenso. Este estudio evalúa el uso de Pylera(R) en un escenario clínico real. PACIENTES Y MÉTODOS: Se llevó a cabo un estudio descriptivo transversal, entre marzo y septiembre de 2016, para evaluar los porcentajes de erradicación de Helicobacter pylori en pacientes tratados con Pylera(R). Los pacientes (naïve o con fallo a terapias previas) fueron tratados durante 10 días. La erradicación fue confirmada usando un test del aliento con urea al menos 30 días después de la finalización del tratamiento. Además se recogieron datos demográficos, clínico-analíticos y relacionados con el tratamiento. RESULTADOS: Fueron incluidos 185 pacientes (51,6±16,19 años); el 63,8% fueron mujeres y el 9,2% tenían historia familiar de cáncer gástrico. La indicación más frecuente fue la dispepsia (55,1%). El 57,8% recibieron Pylera(R) como primera línea de tratamiento. El 95,7% asociaron omeprazol. Se detectó una tasa de erradicación en primera línea de tratamiento del 78,15% por intención de tratar (86,6% por protocolo). No hubo diferencias estadísticamente significativas entre pacientes naïve y los tratados previamente. Nueve pacientes abandonaron el tratamiento (4,9%), 7 debido a efectos secundarios leves y 2 por toma incorrecta. CONCLUSIONES: Pylera(R) tiene unas aceptables tasas de erradicación como primera y segunda línea de tratamiento y muestra un adecuado perfil de seguridad

OBJECTIVE: The resistance of Helicobacter pylori to antibiotics is a growing problem in Spain and eradication rates must be improved. The new Spanish consensus considers quadruple therapy with bismuth as first- or second-line therapy. This study evaluated the use of Pylera(R) in real-life clinical practice. PATIENTS AND METHODS: A cross-sectional descriptive study was conducted to evaluate the eradication rate of Helicobacter pylori in patients treated with Pylera(R) between March and September 2016. Patients (naïve or with previous treatment failure) were treated for 10 days. Eradication was confirmed using a breath test with urea 30 days or more after treatment. In addition, demographic, clinical-analytical and treatment-related data were collected. RESULTS: A total of 185 patients were included (51.6±16.19 years); 63.8% were women and 9.2% had a family history of gastric cancer. The most frequent indication was dyspepsia (55.1%). Approximately 57.8% received Pylera(R) as first-line therapy, while 95.7% received Pylera(R) in combination with omeprazole. A first-line eradication rate of 78.15% was observed in the intention-to-treat population (86.6% per protocol). There were no statistically significant differences between naïve patients and those previously treated. Nine patients abandoned the treatment (4.9%), 7 due to mild side effects and 2 due to incorrect dosing. CONCLUSIONS: Pylera(R) has acceptable eradication rates in first- and second-line therapy and shows a suitable safety profile
