RESUMEN

Antecedentes: el síndrome de intestino irritable tipo estreñimiento (SII-E) es una patología prevalente, compleja y multifactorial que representa un desafío tanto desde el punto de vista diagnóstico como terapéutico. Objetivo: evaluar la efectividad, seguridad y satisfacción de linaclotida en pacientes con SII-E. Métodos: estudio prospectivo, unicéntrico y observacional realizado en pacientes con diagnóstico de SII-E. Los pacientes recibieron tratamiento con linaclotida (Constella(r), Allergan Inc., Irvine, CA), 290 microgramos/24 horas, una cápsula 30 minutos antes del desayuno. La variable primaria de efectividad fue el número de deposiciones por semana. Las variables secundarias incluían el grado de satisfacción y el registro de la frecuencia e intensidad de los síntomas (dolor e hinchazón), medidos mediante una escala visual analógica (EVA) de once niveles (0-10), y recogidas mediante un diario que se entregó al paciente. Resultados: treinta pacientes, todas mujeres, fueron incluidas consecutivamente. La mediana del tiempo de seguimiento fue de 18 meses. La media (deviación estándar [DE]) de deposiciones por semana aumentó desde 0,9 (0,6) al inicio del estudio hasta 4,7 (3,7) al final del mismo (p < 0,0001). Resultados similares fueron observados con el dolor (5,7 [2,3] frente a 3,1 [2,8] al inicio y al final del estudio, respectivamente, p < 0,0001) y con la hinchazón (6,8 [1,6] frente a 2,9 [2,5] al inicio y final del estudio, respectivamente, p < 0,0001). El grado medio (DE) de satisfacción al final del estudio fue 6,7 (3,0). Conclusiones: el tratamiento con linaclotida en pacientes con SII-E en el entorno de la práctica clínica se ha mostrado eficaz y seguro a largo plazo

Background: constipation-predominant irritable bowel syndrome (C-IBS) is a prevalent, complex and multifactorial disorder that represents a challenge in terms of diagnosis and therapeutic management. Objective: to evaluate the effectiveness, safety and treatment satisfaction of linaclotide in C-IBS patients. Methods: prospective, single-center and observational study conducted in patients diagnosed with C-IBS. The patients were treated with linaclotide (Constella(r), Allergan Inc., Irvine, CA), once-daily via an oral capsule of 290-µg, 30 minutes before breakfast. The primary effectiveness endpoint was the number of bowel movements per week. The secondary endpoints included treatment satisfaction and changes from baseline in frequency and severity of symptoms (abdominal pain and bloating). This was assessed via an 11-point visual analog scale (VAS) reported by the patients in a daily register. Results: thirty female patients were consecutively included. The median follow-up time was 18 months. The mean (standard deviation [SD]) number of weekly bowel movements significantly increased from 0.9 (0.6) at baseline to 4.7 (3.9) at the end of follow-up, p < 0.0001. Abdominal pain significantly decreased from 5.7 (2.3) at baseline to 3.1 (2.8) at the end of the follow-up period, p < 0.0001. Similarly, bloating significantly decreased from 6.8 (1.6) to 2.9 (2.5) at the beginning and end of the treatment period, respectively, p < 0.0001. The mean (SD) degree of satisfaction at the end of the study was 6.7 (3.0). Conclusions: long-term linaclotide treatment in patients with C-IBS is effective and safe in the clinical setting

RESUMEN

El citomegalovirus (CMV) es un virus perteneciente a la familia de los Herperviridae. La infección puede causar una enfermedad grave en inmunodeprimidos, sin embargo también puede afectar a inmunocompetentes, y da lugar a cuadros clínicos generalmente autolimitados, aunque se han descrito casos graves que pueden llevar a la muerte. Presentamos un caso de ileítis por CMV con manifestaciones clínicas graves que motivaron intervención quirúrgica urgente en un paciente inmunocompetente(AU)

Cytomegalovirus (CMV) is a virus that belongs to the family of Herpesviridae. Infection can cause a serious disease in immunocompromised patients, but it can also affect immunocompetent patients, creating generally self limiting symptoms. However, in some cases it can be fatal. We present a case of CMV ileitis with serious clinical symptoms that led to an operation in an immunocompetent patient(AU)

RESUMEN

Eosinophilic esophagitis (EE) and gastroesophageal reflux disease (GERD) have overlapping clinical, manometric, endoscopic and histopathologic features. The diagnosis of EE is nowadays based upon the presence of 15 or more eosinophils per high power field (eo/HPF) in esophageal biopsies. We report the cases of two young males suffering from dysphagia and recurrent food impaction with reflux esophagitis and more than 20 eo/HPF in upper-mid esophagus biopsies, both of which became asymptomatic on proton pump inhibitor (PPI) therapy. The first patient also achieved a histologic response, while EE remained in the other patient after effective PPI treatment, as shown by 24-h esophageal pH monitoring. Topical steroid therapy combined with PPI led to complete remission in this latter patient. GERD and EE may be undistinguishable, even by histology, so diagnosis of EE should only be established after a careful correlation of clinical, endoscopic and pathologic data obtained under vigorous acid suppression. These diagnostic difficulties are maximal when both diseases overlap. Limited data are available about this topic, and the interaction between EE and GERD is a matter of debate. In this setting, upper-mid esophagus step biopsies and esophageal pH monitoring of patients on PPI therapy are pivotal to evaluate the role of each disease. A PPI trial is mandatory in patients with a histopathologic diagnosis of EE; in those unresponsive to PPI treatment, EE should be suggested. However, a clinical response to PPI may not rule out quiescent EE, as shown in this report.
