Esofagitis disecante supeEsofagitis disecante superficial: dos casos de una misma entidad poco frecuente / Esophagitis dissecans superficialis: two cases of the same rare entity

La esofagitis disecante superficial (EDS) es una entidad infrecuente que se caracteriza endoscópicamente por el desprendimiento de las capas superficiales del epitelio esofágico e, histológicamente, por el aspecto bitonal del epitelio escamoso esofágico secundario a la necrosis de los estratos más superficiales. La etiología es desconocida, aunque se ha asociado con la ingesta de determinados fármacos, enfermedades autoinmunes, estasis esofágica y procedimientos endoscópicos. Presentamos dos casos: uno de ellos acontece en una mujer tras un episodio de disfagia abrupta y el segundo en un varón con comorbilidades y clínica de dolor epigástrico. La EDS es una patología que hay que considerar en su adecuado contexto clínico y endoscópico, ya que su curso es autolimitado en comparación con otras entidades de evolución tórpida o que precisan un tratamiento específico.

Esophagitis dissecans superficialis (EDS) is a rare disease characterized by sloughing of the superficial esophageal mucosa and, histologically, by the bitonal appearance of the squamous epithelium secondary to necrosis of the most superficial layers. Etiology is uncertain, however, it has been associated with some medications, autoimmune diseases, esophageal stasis and endoscopic procedures. Here, two cases are presented, one of them which appeared in a woman after an episode of dysphagia and another one which occurred to a man with comorbidities and epigastric pain. This entity should be considered due to its self-limiting clinical course, compared to other entities with a more torpid evolution or that require more specific treatment. (AU)

Mixed crawling-type gastric adenocarcinoma.

Crawling-type gastric carcinoma is a rare variant of early gastric carcinoma. Endoscopically, it is a poorly defined tumor with a flat appearance and histologically, especially in a small biopsy, mimic intestinal metaplasia with reactive atypia. We present a case in which, due to the finding of foci of signet ring cell carcinoma, correct management of the patient was carried out.

Intestinal obstruction secondary to Brunner's glands hyperplasia.

Brunner's gland hyperplasia constitutes 10.6% of benign tumors of the duodenum, with an incidence of 0.008%. It is usually an incidental finding during endoscopy or imaging tests as they are small and asymptomatic. In the case of symptomatic tumors, resection of the lesion is indicated. In lesions ≤2 cm, endoscopic resection can be chosen, reserving surgery for larger lesions or endoscopically inaccessible ones. We present the case of a patient with a history of vomiting and hyporexia of months of evolution who presented peptic ulcer perforation and underwent surgery. During follow-up, she presented intestinal obstruction due to pyloric stenosis. Given the impossibility of ruling out a neoplastic process with certainty in diagnostic tests, surgical resection (antrectomy) was decided with an anatomopathological finding of Brunner's gland hyperplasia.

Utilidad clínica de la determinación de niveles de CT-P13, biosimilar de infliximab, en el control de la enfermedad inflamatoria intestinal / Clinical value of CT-P13 trough levels, an infliximab biosimilar, in the management of inflammatory bowel disease

INTRODUCCIÓN: CT-P13 es un fármaco biosimilar de infliximab (IFX), efectivo en pacientes con enfermedad inflamatoria intestinal (EII). La medición de niveles de IFX y anticuerpos anti-IFX forma parte del tratamiento integral de dicha enfermedad. OBJETIVO: Comparar la respuesta clínica en función de un abordaje estrictamente clínico (CLN) o proactivo (PRO) basado en la medición de niveles en la semana 14, en la práctica clínica. MÉTODOS: Estudio prospectivo en pacientes que inician CT-P13 por EII. En el grupo PRO se midieron sistemáticamente los niveles de IFX y de anticuerpos postinducción (semana 14) y se intensificaron aquellos con niveles infraterapéuticos (<3μg/ml), independientemente de la respuesta clínica. RESULTADOS: Se incluyeron 77 pacientes (23 colitis ulcerosa y 54 enfermedad de Crohn). Ambos grupos, PRO (n=41) y CLN (n=36) presentaron una eficacia inicial y a largo plazo sin diferencias significativas. En la semana 14 hubo un 61% de remisión clínica (RC) (58,5% PRO, 63,9% CLN) y un 80,5% de al menos respuesta parcial (RP) (80,5% PRO, 80,6% CLN). En la semana 54 hubo un 68,8% de RC (61% PRO, 77,8% CLN) y un 76,6% de al menos RP (73,2% PRO, 80,6% CLN). De los pacientes en RC en la semana 14 (24 PRO, 23 CLN), 13 del grupo PRO fueron intensificados por niveles infraterapéuticos. En este subgrupo no se observaron diferencias significativas en la pérdida de respuesta secundaria (PRO 0%, CLN 8,7%). CONCLUSIÓN: Un manejo proactivo no mejoró las tasas de respuesta ni la remisión en el primer año. La intensificación de pacientes en RC y niveles infraterapéuticos postinducción no parece prevenir de forma significativa la pérdida de respuesta secundaria en el primer año

INTRODUCTION: CT-P13 is a biosimilar drug of infliximab (IFX), effective in patients with inflammatory bowel disease (IBD). The monitoring of levels of IFX and anti-IFX antibodies is now considered part of the integral management. OBJECTIVE: To compare the clinical response according to a strictly clinical (CLN) or proactive (PRO) approach based on the monitoring of levels in week 14, in clinical practice. METHODS: We conducted a prospective study in IBD patients starting CT-P13. In the PRO group, levels of IFX and post-induction antibodies were systematically measured (week 14) and those with infraterapeutic levels (<3μg/ml) were intensified, irrespective of the clinical response. RESULTS: We included 77 patients (23 ulcerative colitis and 54 Crohn's disease). Both PRO (n=41) and CLN (n=36) groups showed initial and long-term efficacy without significant differences. At week 14, 61% clinical remission (CR) (58.5% PRO, 63.9% CLN) and 80.5% at least partial response (PR) (80.5% PRO, 80.6% CLN). In week 54, 68.8% CR (61% PRO, 77.8% CLN) and 76.6% at least PR (73.2% PRO, 80.6% CLN). Of the patients in CR in week 14 (24 PRO, 23 CLN), 13 of the PRO group were intensified due to infra-therapeutic levels. In this subgroup no significant differences were observed in secondary loss of response (PRO 0%, CLN 8.7%). CONCLUSION: Proactive management does not improve response or remission rates in the first year. The intensification of clinical remission patients with post-induction infratherapeutic levels does not seem to significantly prevent secondary loss of response in the first year

Seguridad de la sedación profunda con propofol controlada por el endoscopista en la colangiopancreatografía retrógrada endoscópica (CPRE). Estudio prospectivo en un hospital terciario / The safety of deep sedation with propofol controlled by the endoscopist in endoscopic retrograde cholangiopancreatography (ERCP): a prospective study in a tertiary hospital

Introducción: el propofol, administrado por el endoscopista con una enfermera entrenada, ha evolucionado como alternativa a la monitorización anestésica y es cada vez más frecuente en la práctica clínica habitual, incluso en endoscopia avanzada. Objetivo: evaluar la seguridad de la sedación profunda con propofol controlada por el endoscopista en pacientes sometidos a colangiopancreatografía retrógrada endoscópica (CPRE). Material y métodos: estudio prospectivo en los pacientes a los que se les realizó CPRE bajo sedación profunda con propofol. Se incluyeron diferentes variables relacionadas con el paciente y se registraron los datos iniciales y finales de la saturación de oxígeno (SatO2), la tensión arterial (TA), y la frecuencia cardiaca (FC) para determinar la presencia de eventos adversos a la sedación (hipoxemia, hipotensión o bradicardia). Resultados: un total de 661 pacientes fueron sometidos a CPRE bajo sedación con propofol durante un periodo de 24 meses. La tasa de eventos adversos registrada fue del 9,7%. La más frecuente fue la hipoxemia (5,7%), seguida de la radicardia (2,4%) y de la hipotensión (1,6%). En el análisis univariante, la aparición de eventos adversos a la sedación (EAS) se asoció a una clasificación de ASA ≥ III (p = 0,026), a pacientes de edad más avanzada (p = 0,009), mayor IMC (p = 0,002) y a un tiempo de exploración más prolongado (p = 0,034). La dosis de inducción de propofol también se relacionó con mayor probabilidad de eventos adversos (p = 0,045), pero no la dosis total de propofol administrado (p = 0,153). En el análisis de regresión logística multivariante, la edad, el índice de masa corporal (IMC) y la duración de la exploración se registran como predictores independientes de EAS (p < 0,05). Conclusión: la sedación profunda con propofol controlada por personal de endoscopia entrenado es un método seguro en procedimientos endoscópicos complejos como la CPRE

Introduction: propofol administered by an endoscopist with a trained nurse has evolved as an alternative to anesthesia monitoring and is increasingly common in the routine clinical practice, even in advanced endoscopy. Objective: to evaluate the safety of deep sedation with endoscopist-controlled propofol in patients undergoing endoscopic retrograde cholangiopancreatography (ERCP). Material and methods: this was a prospective study in patients undergoing ERCP under deep sedation with propofol. Different patient-related variables were included and the initial and final data on oxygen saturation (SatO2), blood pressure (BP) and heart rate (HR) were recorded in order to determine the presence of adverse events due to sedation (hypoxemia, hypotension, or bradycardia). Results: a total of 661 patients underwent ERCP under sedation with propofol over a 24-month period. The rate of recorded adverse events was 9.7%. The most frequent adverse event was hypoxemia (5.7%), followed by bradycardia (2.4%) and hypotension (1.6%). According to the univariate analysis, the occurrence of adverse events due to sedation (AES) was associated with an ASA score ≥ III (p = 0.026), older patients (p = 0.009), higher body mass index (BMI) (p = 0.002) and a longer exploration time (p = 0.034). The induction dose of propofol was also associated with a greater likelihood of adverse events (p = 0.045) but not the total dose of propofol administered (p = 0.153). According to the multivariate logistic regression analysis, age, body mass index (BMI) and the duration of the exploration were independent predictors of SAE (p < 0.05). Conclusion: deep sedation with propofol controlled by trained endoscopy staff is a safe method in complex endoscopic procedures such as ERCP

Anti-tumor necrosis factor alpha (TNF-α) agents have been a great advantage in the treatment of inflammatory bowel disease. The safety profile of these agents is well-known and they can be considered safe when properly used. In clinical practice, the most important adverse events are infections. Other adverse effects are also possible but are much less frequent. However, because of the widespread use of these drugs, these uncommon adverse effects may also occur in clinical practice. We report one of these infrequent adverse events, multiple sclerosis, which is rare but important because of its severity. When neurological symptoms appear during treatment with anti-TNF-α, multiple sclerosis must be ruled out. The diagnosis and therapeutic management of this entity, led by a neurologist with our collaboration, required permanent cessation of anti-TNF-α therapy. Azathioprine, interferon, and even natalizumab, may be used as alternatives in patients who require therapy.
