ABSTRACT

The outbreak of COVID-19 disease has recently spread from its original place in Wuhan, Hubei province, China, to the entire world, and has been declared to be a pandemic by the World Health Organization in March 2020. All countries in America, in particular Chile, show an important increase in COVID-19 cases and deaths. The clinical manifestations of COVID-19 are a broad spectrum, from asymptomatic mild disease, to severe respiratory failure, shock, multiorgan dysfunction and death. Thus, high clinical suspicion and appropriate structure risk stratification are needed. Health care teams in endoscopy units, are at an increased risk of infection by COVID-19 from inhalation of droplets, mucosae contact, probably contamination due to contact with stools. Endoscopic aerosolized associated infections have also been reported. Different societies' recommendations, have recently placed digestive endoscopy (especially upper) among the high risk aerosol generating procedures (AGPs). In addition, live virus has been found in patient stools. On top of this, the infected health professionals may transmit the infection to their patients. Health care infection prevention and control (HCIPC), has been shown to be effective in assuring the safety of both health care personnel and patients. This is not limited to the correct use of personal protective equipment (PPE), but is based on a clear, detailed and well communicated HCIPC strategy, risk stratification, use of PPE, and careful interventions in patients with moderate and high risk of COVID-19. A conscientious approach regarding limited resources is important, as the simultaneous outbreak in all countries heavily affects the availability of health supplies. The Chilean Gastroenterology Society (SChGE) and Digestive Endoscopy Association of Chile (ACHED) are joining to provide continued updated guidance in order to assure the highest level of protection against COVID-19, for both patients and health care workers. This guideline will be updated online as needed.


El brote de la enfermedad denominada COVID-19, se ha extendido desde su origen en Wuhan, provincia de Hubei, China, a todo el mundo. La Organización Mundial de la Salud lo declaró pandemia en marzo de 2020. Todos los países de América, en especial Chile, presentan incremento de casos y fallecidos. Las manifestaciones clínicas de COVID-19 van desde una enfermedad leve, hasta insuficiencia respiratoria severa, shock, disfunción orgánica y muerte. Se necesita una alta sospecha clínica y una adecuada estratificación del riesgo. El equipo de salud en las unidades de endoscopia, tiene un mayor riesgo de COVID-19 que otras unidades clínicas y de apoyo diagnóstico, dada la mayor exposición a inhalación de gotas, contacto posible con mucosas y contaminación por contacto con deposiciones. Recomendaciones de diferentes sociedades colocan la endoscopia digestiva (especialmente la esofagogastroscopia o endoscopia digestiva alta, EDA) entre los procedimientos generadores de aerosoles (PGA) de alto riesgo. Además, se han encontrado virus viables en las deposiciones de los pacientes. Potencialmente, los profesionales de la salud infectados podrían contagiar a los pacientes. Se ha demostrado que la prevención y control de infecciones asociadas a la atención de salud (IAAS), son efectivos para garantizar la seguridad tanto del personal de salud, como de los pacientes. Esto no es solamente el correcto uso del equipo de protección personal (EPP), sino que se basa en una clara estrategia de IAAS, bien comunicada, con estratificación de riesgo, uso de EPP e intervenciones correctas en pacientes con riesgo moderado y alto. Es relevante un enfoque sobre los limitados recursos, dado la simultaneidad del brote en todos los países, que afecta la disponibilidad de insumos. La Sociedad Chilena de Gastroenterología (SChGE) y la Asociación Chilena de Endoscopia Digestiva (ACHED) publican esta guía actualizada para apoyar las buenas prácticas contra COVID-19, tanto para pacientes como para el equipo de salud. Esta guía podrá tener actualizaciones según avance la información disponible.

ABSTRACT

We report the case of a 19-year-old patient, with a history of traumatic liver damage, but with a normal liver profile at her first discharge; 1 month after the event, with post-traumatic stress disorder, treatment with 25 mg of sertraline was started every day; one month later, she develops severe hepatotoxicity without a specific etiology. According to the Naranjo algorithm, it is attributed as a probable case of sertraline hepatotoxicity. Management is carried out with support measures and suspension of the medication, and the patient recovers until she is asymptomatic, currently has normal liver tests

ABSTRACT

The prevalence of Celiac disease in the general population is approximately 1% and remains undiagnosed in a significant proportion of individuals. Its clinical presentation includes the classical malabsorption syndrome, unspecific and extra-intestinal manifestations, and silent celiac disease. The serologic diagnosis has an elevated sensitivity and specificity and, at least in adult population, it must be confirmed by biopsy in every case. Diagnosis in subjects already on gluten free diet includes HLA typing and gluten challenge with posterior serologic and histologic evaluation. The core of the treatment is the gluten free diet, which must be supervised by an expert nutritionist. Monitoring must be performed with serology beginning at 3-6 months, and with histology two years after the diagnosis, unless the clinical response is poor. Poor disease control is associated with complications such as lymphoma and small bowel adenocarcinoma. In the future, it is likely that new pharmacologic therapies will be available for the management of celiac disease.

ABSTRACT

La Enfermedad Celiaca (EC) tiene una prevalencia cercana al 1% de la población general y se considera que hay un número importante de pacientes asintomáticos no diagnosticados. Su presentación clínica es variable comprendiendo el clásico síndrome de malabsorción, formas menores y la EC silente. El diagnóstico serológico tiene una elevada sensibilidad y especificidad y siempre debe confirmarse con biopsia. El diagnóstico en pacientes en dieta libre de gluten incluye test de tipificación de HLA y prueba de dieta con gluten con estudio serológico e histológico posterior. El pilar del tratamiento es la dieta libre de gluten, que debe ser supervisada por un nutriólogo con experiencia. La monitorización de la terapia debe realizarse con serología. La EC mal controlada puede determinar complicaciones como linfoma y adenocarcinoma de intestino delgado. En el futuro es probable que nuevas terapias farmacológicas sean de utilidad en el manejo de la EC.

ABSTRACT

Biological therapy plays an important role in the treatment of inflammatory bowel disease (IBD). However, the use of these drugs is limited due to fears about their side effects. Aim: To report the experience with the use of infliximab/adalimumab in IBD patients in a public hospital. Material and Methods: Descriptive study of a historical cohort of IBD patients treated with infliximab and adalimumab between April 2012 and July 2014. The clinical response was considered favourable when general, intestinal and extra intestinal symptoms subsided after the induction therapy. In addition, endoscopic and/or imaging response was evaluated at three and six months of treatment. Results: Fifteen out of 162 patients, aged 17 to 52 years (7 women) were included. Seven had Crohn´s Disease, 7 had ulcerative colitis and one had non-classifiable IBD. Biological therapy was indicated due to conventional refractory disease in all patients. All patients received combined treatment with immunosuppressive medications. A favorable clinical response was observed in 93 percent after induction therapy and 73 percent showed endoscopic/imagining remission after 3-6 months. Only one patient experienced side effects associated to the biological therapy, which did not result in discontinuation or treatment interruption. Conclusions: In this cohort of IBD patients treated in a public hospital, the use of infliximab/adalimumab was associated with favorable clinical and endoscopic evolution, post induction therapy with no major side effects.


La terapia biológica tiene un papel fundamental en el tratamiento de la enfermedad inflamatoria intestinal (EII). Sin embargo, el uso de estos fármacos es escaso debido a los costos y los temores sobre los efectos secundarios. Objetivo: Dar a conocer la experiencia en el uso de infliximab/adalimumab en pacientes con EII atendidos en un hospital público de nuestro país. Material y Métodos: Estudio descriptivo de una cohorte histórica de pacientes con EII tratados con infliximab y adalimumab entre abril de 2012 y julio de 2014. La respuesta clínica fue considerada favorable cuando los síntomas generales, intestinales y extra-intestinales desaparecieron después de la terapia de inducción. Además se evaluó la respuesta endoscópica/radiológica a los 3 y 6 meses de tratamiento. Resultados: De un total de 162 pacientes con EII, 15 fueron tratados con terapia biológica, con edad entre 17-52 años (7 mujeres). Siete presentaban el diagnóstico de enfermedad de Crohn, siete colitis ulcerosa y uno EII no clasificable. En todos se inició terapia biológica debido a la presencia de refractariedad a la terapia convencional. Todos recibieron terapia combinada con inmunosupresores. Se observó una respuesta clínica favorable en 93 por ciento después de la terapia de inducción y 73 por ciento tuvo una mejoría endoscópica después de 3-6 meses. Sólo un paciente presentó un evento adverso a terapia biológica, el cual no motivó la interrupción del tratamiento. Conclusiones: En esta cohorte de pacientes con EII tratados en un hospital público, el uso de infliximab/adalimumab se asoció con mejoría clínica y endoscópica post terapia de inducción, sin mayores efectos secundarios.

ABSTRACT

Infection (CDI) is increasing both in the hospital environment as in the outpatient setting, and is associated with prior use of antibiotics, hospitalizations and inflammatory bowel disease (IBD), among others. It is also characterized by a high rate of recurrence with the usual antibiotic treatment, which increases with greater number of episodes, reaching up to 65 percent. In this context, the transplantation of fecal microbiota (FMT) emerges as recurrent CDI therapy, achieving success rates exceeding 90 percent, including in IBD patients, with minimum rates of recurrence. To achieve such efficiency, the colonization by the donated microbiota in the recipient is critical. The role of FMT is still unclear in IBD therapy not associated with CDI. Although there are great differences in the methodology of FMT, the process has been standardized even creating banks of frozen fecal samples, without reducing its effectiveness. FMT is a safe procedure, without serious adverse events, and accepted by the potential beneficiary population. There are few reported cases of refractory CDI management with FMT. Since 2012, the FMT in CDI and IBD publications have increased significantly, but in our country there are only few reports of this therapeutic strategy. We present a patient with ulcerative colitis and conventional antimicrobial management resistant CDI, which was successfully treated with FMT in a public hospital in Chile.


La infección por Clostridium difficile (ICD) está en aumento tanto en el ambiente hospitalario como ambulatorio, y se asocia a uso previo de antibióticos, hospitalización y enfermedades inflamatorias intestinales (EII), entre otros. Se caracteriza además por su alta tasa de recurrencia con el tratamiento antimicrobiano habitual, que aumenta con el mayor número de episodios alcanzando hasta 65 por ciento. En este contexto, el trasplante de microbiota fecal (TMF) surge como terapia para la ICD recurrente, logrando tasas de éxito superiores a 90 por ciento, incluyendo pacientes con EII, con mínimas tasas de recurrencia. Para lograr esa eficacia, la colonización por la microbiota donada en el receptor es fundamental. Aún no está claro el rol del TMF en la terapia de EII no asociada a ICD. Aunque existe gran heterogeneidad en la metodología del TMF, el proceso se ha ido estandarizando incluso hasta llegar a la creación de bancos de muestra fecal congelada, sin disminuir su efectividad. El TMF es un procedimiento seguro, sin eventos adversos graves y aceptado por la población potencialmente beneficiaria de él. Existen pocos casos publicados de manejo de ICD refractaria con TMF. Desde el 2012 el número de publicaciones sobre TMF en ICD y en EII ha aumentado considerablemente, sin embargo, en nuestro país los reportes sobre esta estrategia terapéutica son escasos. Presentamos el caso de un paciente con colitis ulcerosa e ICD refractaria al manejo antimicrobiano habitual, que se trató exitosamente con TMF en un hospital público de Chile.
