Influencia del estilo de vida occidental en la disbiosis y sus consecuencias sobre la salud

La microbiota intestinal es en la actualidad un campo de estudio de creciente interés e investigación. Tal investigación se ha visto potenciada por el desarrollo de las diferentes técnicas de estudio, que han permitido alcanzar un nivel de conocimiento sobre la microbiota insospechado hasta hace unos años. Así, se le han atribuido un número creciente de funciones a este ecosistema presente en nuestro intestino, y se le ha relacionado con diversas condiciones de salud y enfermedad. Se ha puesto en evidencia que resulta fundamental la existencia de unas condiciones de equilibrio y homeostasis en la composición de la microbiota. La alteración de esta beneficiosa composición y función de la microbiota para el organismo podría condicionar o verse implicada en la patogenia de distintas enfermedades y es lo que se ha conocido en la literatura como disbiosis. En el presente artículo de revisión analizaremos la posible implicación de la disbiosis en las alteraciones de la barrera intestinal, como posible mecanismo por el que se asocia a alteraciones y problemas sistémicos. Del mismo modo, teniendo en cuenta la gran cantidad de factores que modifican la microbiota intestinal, la presente revisión trata de encontrar en la literatura médica actual las posibles causas de este proceso, y determinar cuál es su papel e importancia. Se analizará en este contexto la influencia del estilo de vida occidental, evaluando su papel como causa de disbiosis y las consecuencias que trae consigo. Del mismo modo se pretenden identificar las posibles estrategias que conduzcan a emplear este conocimiento como posible armamento preventivo y/o terapéutico frente a la disbiosis

Risk Factors for COVID-19 in Inflammatory Bowel Disease: A National, ENEIDA-Based Case–Control Study (COVID-19-EII)

(1) Scant information is available concerning the characteristics that may favour the acquisition of COVID-19 in patients with inflammatory bowel disease (IBD). Therefore, the aim of this study was to assess these differences between infected and noninfected patients with IBD. (2) This nationwide case-control study evaluated patients with inflammatory bowel disease with COVID-19 (cases) and without COVID-19 (controls) during the period March-July 2020 included in the ENEIDA of GETECCU. (3) A total of 496 cases and 964 controls from 73 Spanish centres were included. No differences were found in the basal characteristics between cases and controls. Cases had higher comorbidity Charlson scores (24% vs. 19%; p = 0.02) and occupational risk (28% vs. 10.5%; p < 0.0001) more frequently than did controls. Lockdown was the only protective measure against COVID-19 (50% vs. 70%; p < 0.0001). No differences were found in the use of systemic steroids, immunosuppressants or biologics between cases and controls. Cases were more often treated with 5-aminosalicylates (42% vs. 34%; p = 0.003). Having a moderate Charlson score (OR: 2.7; 95%CI: 1.3-5.9), occupational risk (OR: 2.9; 95%CI: 1.8-4.4) and the use of 5-aminosalicylates (OR: 1.7; 95%CI: 1.2-2.5) were factors for COVID-19. The strict lockdown was the only protective factor (OR: 0.1; 95%CI: 0.09-0.2). (4) Comorbidities and occupational exposure are the most relevant factors for COVID-19 in patients with IBD. The risk of COVID-19 seems not to be increased by immunosuppressants or biologics, with a potential effect of 5-aminosalicylates, which should be investigated further and interpreted with caution

Nationwide COVID-19-EII Study : Incidence, Environmental Risk Factors and Long-Term Follow-Up of Patients with Inflammatory Bowel Disease and COVID-19 of the ENEIDA Registry

We aim to describe the incidence and source of contagion of COVID-19 in patients with IBD, as well as the risk factors for a severe course and long-term sequelae. This is a prospective observational study of IBD and COVID-19 included in the ENEIDA registry (53,682 from 73 centres) between March-July 2020 followed-up for 12 months. Results were compared with data of the general population (National Centre of Epidemiology and Catalonia). A total of 482 patients with COVID-19 were identified. Twenty-eight percent were infected in the work environment, and 48% were infected by intrafamilial transmission, despite having good adherence to lockdown. Thirty-five percent required hospitalization, 7.9% had severe COVID-19 and 3.7% died. Similar data were reported in the general population (hospitalisation 19.5%, ICU 2.1% and mortality 4.6%). Factors related to death and severe COVID-19 were being aged ≥ 60 years (OR 7.1, 95% CI: 1.8-27 and 4.5, 95% CI: 1.3-15.9), while having ≥2 comorbidities increased mortality (OR 3.9, 95% CI: 1.3-11.6). None of the drugs for IBD were related to severe COVID-19. Immunosuppression was definitively stopped in 1% of patients at 12 months. The prognosis of COVID-19 in IBD, even in immunosuppressed patients, is similar to that in the general population. Thus, there is no need for more strict protection measures in IBD
