Long-term use of somatostatin analogs for chronic gastrointestinal bleeding in hereditary hemorrhagic telangiectasia.

Background: Chronic bleeding due to gastrointestinal (GI) involvement in patients with hemorrhagic hereditary telangiectasia (HHT) can provoke severe anemia with high red blood cells (RBC) transfusion requirements. However, the evidence about how to deal with these patients is scarce. We aimed to assess the long-term efficacy and safety of somatostatin analogs (SA) for anemia management in HHT patients with GI involvement. Methods: This is a prospective observational study including patients with HHT and GI involvement attended at a referral center. SA were considered for those patients with chronic anemia. Anemia-related variables were compared in patients receiving SA before and during treatment. Patients receiving SA were divided into responders (patients with minimal hemoglobin levels improvement >10 g/L and maintaining hemoglobin levels ≥80 g/L during treatment), and non-responders. Adverse effects during follow-up were collected. Results: Among 119 HHT patients with GI involvement, 67 (56.3%) received SA. These patients showed lower minimal hemoglobin levels (73 [60-87] vs. 99 [70.2-122.5], p < 0.001), and more RBC transfusion requirements (61.2% vs. 38.5%, p = 0.014) than patients without SA therapy. Median treatment period was 20.9 ± 15.2 months. During treatment, there was a statistically significant improvement in minimum hemoglobin levels (94.7 ± 29.8 g/L vs. 74.7 ± 19.7, p < 0.001) and a reduction of patients with minimal hemoglobin levels <80 g/L (39 vs. 61%, p = 0.007) and RBC transfusions requirement (33.9% vs. 59.3%, p < 0.001). Sixteen (23.9%) patients showed mild adverse effects, mostly diarrhea or abdominal pain, leading to treatment discontinuation in 12 (17.9%) patients. Fifty-nine patients were eligible for efficacy assessment and 32 (54.2%) of them were considered responders. Age was associated with non-responder patients, OR 95% CI; 1.070 (1.014-1.130), p = 0.015. Conclusion: SA can be considered a long-term effective and safe option for anemia management in HHT patients with GI bleeding. Older age is associated with poorer response.

EPAGE no es una estrategia eficaz para la gestión de colonoscopias durante la pandemia por COVID-19 / The EPAGE guidelines are not an effective strategy for managing colonoscopies during the COVID-19 pandemic

Introducción: La pandemia producida por el virus SARS-CoV-2 ha generado un grave impacto en el funcionamiento de las unidades de endoscopia digestiva. La Asociación Española de Gastroenterología y la Sociedad Española de Endoscopia Digestiva (AEG-SEED) han propuesto la utilización de la guía European Panel on the Appropriateness of Gastrointestinal Endoscopy II (EPAGE) para la gestión de las colonoscopias pospuestas.Objetivo: Evaluar la guía EPAGE como herramienta de gestión en comparación con el test de sangre oculta en heces inmunológico (TSOHi) y con una calculadora de riesgo (CR), que incluye la edad, el sexo y el TSOHi, para la detección de cáncer colorrectal (CCR) y lesión significativa colónica (LSC).Métodos: Estudio unicéntrico prospectivo. Se incluyeron 743 pacientes derivados para una colonoscopia diagnóstica. Se clasificó cada solicitud según EPAGE en apropiada, indeterminada e inapropiada. Se les entregó un TSOHi y se calculó el valor de la CR.ResultadosEl TSOHi (p<0,001), pero no EPAGE (p = 0,742), fue una variable independiente de riesgo de CCR. El área bajo la curva receiver operating characteristic (ROC) de EPAGE, TSOHi y CR fue: 0,61(IC 95% 0,49 a 0,75), 0,95 (0,93 a 0,97) y 0,90 (0,87 a 0,93) para CCR; y 0,55 (0,49 a 0,61), 0,75 (0,69 a 0,813) y 0,78 (0,73 a 0,83) para LSC, respectivamente. El número necesario de colonoscopias para detectar un CCR y una LSC fue de 38 y siete para EPAGE, de siete y dos para TSOHi, y de 19 y cuatro para CR ≥ cinco puntos, respectivamente.Conclusión: La EPAGE, a diferencia del TSOHi, no es adecuada para seleccionar a los pacientes candidatos a colonoscopia diagnóstica para la detección de CCR. El TSOHi, en combinación con la edad y el sexo, es la estrategia correcta para gestionar la demanda de endoscopia en un escenario de acceso restrictivo.

Introduction: The pandemic caused by the SARS-CoV-2 virus has had a serious impact on the functioning of gastrointestinal endoscopy Units. The Asociación Española de Gastroenterología (AEG) and the Sociedad Española de Endoscopia Digestiva (SEED) have proposed the EPAGE guidelines for managing postponed colonoscopies.ObjectiveTo evaluate the EPAGE guidelines as a management tool compared to the immunologic faecal occult blood test (iFOBT) and compared to risk score (RS) that combines age, sex and the iFOBT for the detection of colorectal cancer (CRC) and significant bowel disease (SBD).Methods: A prospective, single-centre study enrolling 743 symptomatic patients referred for a diagnostic colonoscopy. Each order was classified according to the EPAGE guidelines as appropriate, indeterminate or inappropriate. Patients underwent an iFOBT and had their RS calculated.Results: The iFOBT (p<0.001), but not the EPAGE guidelines (p = 0.742), was an independent predictive factor of risk of CRC. The ROC AUCs for the EPAGE guidelines, the iFOBT and the RS were 0.61 (95% CI 0.49-0.75), 0.95 (0.93-0.97) and 0.90 (0.87-0.93) for CRC, and 0.55 (0.49-0.61), 0.75 (0.69-0.813) and 0.78 (0.73-0.83) for SBD, respectively. The numbers of colonoscopies needed to detect a case of CRC and a case of SBD were 38 and seven for the EPAGE guidelines, seven and two for the iFOBT, and 19 and four for a RS ≥5 points, respectively.Conclusion: The EPAGE guidelines, unlike the iFOBT, is not suitable for screening candidate patients for a diagnostic colonoscopy to detect CRC. The iFOBT, in combination with age and sex, is the most suitable strategy for managing demand for endoscopy in a restricted-access situation

Interstitial and Granulomatous Lung Disease in Inflammatory Bowel Disease Patients.

BACKGROUND: Interstitial lung [ILD] disease and granulomatous lung disease [GLD] are rare respiratory disorders that have been associated with inflammatory bowel disease [IBD]. Clinical presentation is polymorphic and aetiology is unclear. METHODS: This was an ECCO-CONFER project. Cases of concomitant ILD or GLD and IBD, or drug-induced ILD/GLD, were collected. The criteria for diagnosing ILD and GLD were based on definitions from the American Thoracic Society and the European Respiratory Society and on the discretion of reporting clinician. RESULTS: We identified 31 patients with ILD. The majority had ulcerative colitis [UC] [n = 22]. Drug-related ILD was found in 64% of these patients, 25 patients [80.6%] required hospitalisation, and one required non-invasive ventilation. The causative drug was stopped in all drug-related ILD, and 87% of patients received systemic steroids. At follow-up, 16% of patients had no respiratory symptoms, 16% had partial improvement, 55% had ongoing symptoms, and there were no data in 13%. One patient was referred for lung transplantation, and one death from lung fibrosis was reported. We also identified 22 GLD patients: most had Crohn's disease [CD] [n = 17]. Drug-related GLD was found in 36% of patients and 10 patients [45.4%] required hospitalisation. The causative drug was stopped in all drug-related GLD, and 81% of patients received systemic steroids. Remission of both conditions was achieved in almost all patients. CONCLUSIONS: ILD and GLD, although rare, can cause significant morbidity. In our series, over half of cases were drug-related and therefore focused pharmacovigilance is needed to identify and manage these cases.

Gastrointestinal Bleeding in Patients with Hereditary Hemorrhagic Telangiectasia: Risk Factors and Endoscopic Findings.

BACKGROUND: We aimed to describe risk factors for gastrointestinal (GI) bleeding and endoscopic findings in patients with hereditary hemorrhagic telangiectasia (HHT). METHODS: This is a prospective study from a referral HHT unit. Endoscopic tests were performed when there was suspicion of GI bleeding, and patients were divided as follows: with, without, and with unsuspected GI involvement. RESULTS: 67 (27.9%) patients with, 28 (11.7%) patients without, and 145 (60.4%) with unsuspected GI involvement were included. Age, tobacco use, endoglin (ENG) mutation, and hemoglobin were associated with GI involvement. Telangiectases were mostly in the stomach and duodenum, but 18.5% of patients with normal esophagogastroduodenoscopy (EGD) had GI involvement in video capsule endoscopy (VCE). Telangiectases ≤ 3 mm and ≤10 per location were most common. Among patients with GI disease, those with hemoglobin < 8 g/dL or transfusion requirements (65.7%) were older and had higher epistaxis severity score (ESS) and larger telangiectases (>3 mm). After a mean follow-up of 34.2 months, patients with GI involvement required more transfusions and more emergency department and hospital admissions, with no differences in mortality. CONCLUSIONS: Risk factors for GI involvement have been identified. Patients with GI involvement and severe anemia had larger telangiectases and higher ESS. VCE should be considered in patients with suspicion of GI bleeding, even if EGD is normal.

Rendimiento de la colonoscopia en la hemorragia digestiva baja / Diagnostic performance of colonoscopy in lower gastrointestinal bleeding

La hemorragia digestiva baja es una urgencia médica frecuente cuyo pronóstico es, habitualmente, favorable, pero que genera un elevado consumo de recursos. La colonoscopia, previa preparación del colon, es la prueba de primera elección por su elevado rendimiento diagnóstico, seguridad y la posibilidad de ofrecer un tratamiento endoscópico. La colonoscopia urgente tiene ventajas respecto a la electiva demostrando un mayor rendimiento diagnóstico y una mayor tasa de detección de estigmas de sangrado reciente, hecho que se traduce en una mayor probabilidad de ofrecer un tratamiento endoscópico. Recientemente, se han publicado modelos predictivos de gravedad y recidiva hemorrágica que permiten racionalizar el consumo de recursos, fundamentalmente, reduciendo la estancia hospitalaria de los pacientes de bajo riesgo. No obstante, no se ha establecido el momento óptimo de la colonoscopia urgente y existe controversia acerca del impacto del tratamiento endoscópico en el pronóstico de la enfermedad (AU)

Lower gastrointestinal bleeding is a common medical emergency that usually has a favorable prognosis. However, these events generate high resource use. The procedure of choice is colonoscopy with prior colonic preparation due to its high diagnostic performance and safety and the possibility of endoscopic therapy. Emergency colonoscopy has advantages over elective colonoscopy, showing higher diagnostic yield and superior detection of stigmata of recent bleeding, increasing the probability of endoscopic treatment. Predictive models of bleeding severity and recurrence have been published, allowing resource use to be rationalized, mainly by reducing hospital stay in low-risk patients. Nevertheless, the optimal timing of emergency colonoscopy has not been established and the impact of endoscopic treatment on prognosis is controversial (AU)

Papel de la cirugía en el manejo de las complicaciones biliares tras el trasplante hepático / Role of surgery in the management of biliary complications after liver transplantation

Resumen El manejo de las complicaciones biliares (CB) postrasplante hepático ha evolucionado en los últimos años. Resumen Los objetivos de este estudio fueron, analizar la incidencia y el manejo de las CB en nuestro centro en 1.000 transplantes hepáticos; y estudiar específicamente el manejo de las estenosis anastomóticas (EA). Resultados la incidencia de CB fue del 23%. Se dieron 76 casos de fístula biliar, 106 casos de estenosis anastomóticas, 46 casos de estenosis no-anastomóticas, 42 coledocolitiasis y 19 otras complicaciones. Resultados De los 106 casos de estenosis anastomóticas, se indicó tratamiento radiológico (CPRE o CTPH) en 62 casos. En 38 casos (33%), la estenosis anastomótica se resolvió mediante tratamiento quirúrgico, en 18 tras previo tratamiento radiológico. La morbilidad y mortalidad relacionada con el tratamiento radiológico de las CB fue discretamente superior (morbilidad: Quir: 4 (18%) vs Radiol: 20 (32%); p=0,2 y mortalidad: Quir: 0% vs Radiol: 8 (11%); p=0,23).Resultados De los 46 pacientes con estenosis no anastomóticas, 29 (63%) fueron tratados mediante retrasplante. Conclusión El tratamiento quirúrgico tiene un papel relevante en el manejo de las CB postrasplante hepático, y es el tratamiento de elección en algunos casos de estenosis anastomóticas. El retrasplante, sin manipulación previa, es el tratamiento de elección en los pacientes con estenosis no anastomóticas (AU)

Abstract Management of biliary tract complications (BTC) after liver transplantation (LT) has progressed in recent years. The aims of this study were, to analyse the incidence and management in our institution of BTC after 1000LT; and to study the management of patients with anastomotic strictures (AS). Results The incidence of BTC was 23%. There were 76 cases of bile leak, 106 cases of anastomotic strictures, 46 non-anastomotic strictures, 42 choledocolithiasis and 19 other complications. Results Among 106 cases of anastomotic strictures, radiological treatment, either PTC or ERCP, was initially indicated in 62. The AS of 38 patients (33%) were resolved with surgical treatment, 18 of them after a previous attempt at radiological treatment. Patients who were treated initially by radiologically required more procedures. Morbidity and mortality related to BTC were slightly higher in the group of patients treated by radiology (morbidity: surgical: 4 (18%) vs. radiological: 20 (32%); p=0.2 and mortality: surgical: 0% vs. radiological: 8 (11%); p=0.23).Results Among 46 patients with non-anastomotic strictures, 29 were resolved with retransplantation (63%). Conclusions Surgery has a significant role in the management of BTC, and is the treatment of choice in some cases of anastomotic strictures. Retransplantation may be the preferred option in patients with non-anastomotic strictures (AU)

Patient with hepatocellular carcinoma related to prior acute arsenic intoxication and occult HBV: epidemiological, clinical and therapeutic results after 14 years of follow-up.

Little is known about the long-term survivors of acute arsenic intoxication. We present here a clinical case report of a man with chronic hepatitis B virus (HBV) infection who developed hepatocellular carcinoma four years after acute arsenic poisoning. HBsAg was detected in serum in 1990 when he voluntarily donated blood. In 1991, the patient suffered from severe psychological depression that led him to attempt suicide by massive ingestion of an arsenic-containing rodenticide. He survived with polyneuropathy and paralysis of the lower limbs, and has been wheelchair-bound since then. During participation in a follow-up study conducted among HBV carriers, abdominal ultrasound detected a two-centimeter liver mass consistent with hepatocellular carcinoma. The tumor was confirmed by computed tomography (CT) and magnetic resonance image (MRI). Because of his significant comorbidity, the patient received palliative treatment with transarterial lipiodol chemoembolization (TACE) on three occasions (1996, 1997 and 1999). At his most recent visit in May 2005, the patient was asymptomatic, liver enzymes were normal and the tumor was in remission on ultrasound.
