Efectividad Del Tratamiento De La Hepatitis C En Pacientes Controlados Desde La Consulta De Atención Farmacéutica / Effectiveness of hepatitis C antiviral treatment in attended patients from the outpatient pharmacy consultation

OBJETIVOS: Determinar la efectividad del tratamiento de la hepatitis C crónica definida como la respuesta viral sostenida a las 12 semanas (RVS12) tras la finalización del tratamiento con fármacos antivirales de acción directa (AAD) (glecaprevir/pibrentasvir, sofosbuvir/velpatasvir, sofosbuvir/velpatasvir/voxilaprevir y grazoprevir/elbasvir) en pacientes atendidos en la consulta de farmacia ambulatoria. MÉTODOS: estudio retrospectivo que incluye los pacientes atendidos por farmacia que iniciaron tratamiento con AAD entre el 1 de diciembre de 2017 y el 31 de mayo de 2018. Se registraron datos demográficos, de la enfermedad, grado de adherencia y consultas sobre el tratamiento (interacciones, efectos adversos y otras). RESULTADOS: Se incluyeron 205 pacientes con diferentes genotipos de hepatitis C, estados de fibrosis y grados de morbilidad. La efectividad fue del 99,5%, similar a la reportada en los ensayos clínicos. CONCLUSIONES: Estos resultados se asemejan a los obtenidos en las consultas de farmacia en Estados Unidos, funcionando desde hace más de diez años

OBJECTIVE: To determine the effectiveness of the treatment of chronic hepatitis C determined as the sustained viral response at 12 weeks (SVR12) after the end of treatment with direct-acting antiviral drugs (DAA) (glecaprevir/pibrentasvir, sofosbuvir/velpatasvir, sofosbuvir/velpatasvir/voxilaprevir and grazoprevir/elbasvir) in attended patients from the outpatient pharmacy consultation. METHOD: a retrospective study that includes patients attended by pharmacists who started treatment between December 1, 2017 and May 31, 2018. Demographic data, disease, adherence and treatment consultations were recorded (interactions, adverse effects and others). RESULTS: Two hundred and five patients were included, with different hepatitis C genotypes, fibrosis states and morbidity levels. Effectiveness was 99.5%, similar to that of clinical trials. CONCLUSIONS: These results resemble those obtained in pharmacy consultations in the United States, operating for more than ten years

Predictive variables of sustained virological response after early discontinuation of triple therapy with telaprevir for genotype-1 HCV infection / Variables pronósticas de respuesta virológica sostenida tras la interrupción precoz del tratamiento triple con telaprevir de la infección por genotipo 1 del virus de la hepatitis C

BACKGROUND: Pivotal phase studies of telaprevir (TLV) and boceprevir (BOV) showed 10-56% rates of early treatment interruption. However, there have been no reports on the sustained virological response (SVR) rates of these patients. AIM: To assess the SVR rate in a large cohort of patients who discontinued triple therapy with TLV or BOV for reasons other than stopping rules and to identify variables predicting SVR. MATERIAL AND METHOD: A survey was sent to 15 hospitals in Catalonia asking them to report all TLV/BOV treatments finished by 31 May 2014. Demographic, clinical, laboratory, liver fibrosis and therapeutic data were recorded for treatments with early discontinuation. Logistic regression analysis, ROC curves and prognostic assessment of the variables identified were calculated. RESULTS: Twelve hospitals responded to the survey, representing 467 treatments and 121 (21.2%) early discontinuations, 76 (62.8%) due to stopping rules and 45 (37.2%) for other reasons. Early discontinuation was more frequent with BOV [38.2% (50/131) versus 21.1% (71/336) p < 0.005], mainly due to stopping rules [78% (39/50) versus 52.1% (37/71); p = 0.004]. SVR was achieved in 21/121 patients (17.4%), 19/71 (26.8%) treated with TLV and 2/50 (4.0%) treated with BOV. In patients discontinuing treatment for reasons other than stopping rules, SVR was achieved in 19/37 (55.9%) treated with TLV and in 2/11 (18.2%) treated with BOV. The SVR rate in patients treated with TLV who discontinued due to a severe adverse event was 61.5% (16/26). A logistic regression analysis was performed only with triple therapy with TLV and early discontinuation. The predictive variables of SVR were undetectable HCV-RNA at treatment week 4 and treatment length longer than 11 weeks. Treatment duration longer than 11 weeks showed the best accuracy (0.794), with a positive predictive value of 0.928. CONCLUSIONS: Early discontinuation of TLV-based triple therapy due to reasons other than stopping rules still have a significant SVR rate (55.9%). Undetectable HVC-RNA at week 4 of treatment and treatment duration longer than 11 weeks are predictive of SVR in this subset of patients

ANTECEDENTES: Los estudios de registro de telaprevir (TLV) y boceprevir (BOV) han mostrado tasas de interrupción precoz del tratamiento del 10-56%, pero no se ha comunicado la respuesta virológica sostenida (RVS) de estos pacientes. OBJETIVOS: Analizar la RVS, y los factores predictivos de esta, en una cohorte extensa de pacientes que pararon precozmente el tratamiento triple con TLV/BOV por causas diferentes a reglas de parada. MATERIAL Y MÉTODO: Se envió a 15 de hospitales de Cataluña un cuestionario relativo a los tratamientos con TLV/BOV finalizados antes del 31 de mayo de 2014, incluyendo información clínica, analítica, elastométrica y terapéutica de aquellos interrumpidos precozmente. Se realizaron análisis de regresión logística, curvas ROC y estimaciones pronósticas de las variables identificadas. RESULTADOS: Contestaron la encuesta 12 hospitales, sumando un total de 467 tratamientos con 121 (21,2%) interrupciones precoces del mismo, 76 (62,8%) por reglas de parada y 45 (37,2%) por otras causas. Hubo más paradas precoces en los tratamientos con BOV (38,2% [50/131] versus 21,1% [71/336]; p < 0,005), principalmente debidas a reglas de parada (78% [39/50] versus 52,1% [37/71]; p = 0,004). Alcanzaron RVS 21/121 pacientes (17,4%), 19/71 (26,8%) tratados con TLV y 2/50 (4,0%) tratados con BOV. En los pacientes que pararon el tratamiento por causas distintas a reglas de parada se alcanzó la RVS en 19/37 (55,9%) tratados con TLV y en 2/11 (18,2%) tratados con BOV. Los pacientes tratados con TLV que pararon el tratamiento por efecto adverso grave tuvieron una tasa de RVS del 61,5% (16/26). El análisis de regresión logística se hizo solo con los tratamientos triples con TLV parados precozmente. Las variables predictivas de RVS fueron el ARN-VHC indetectable en semana 4 y la duración del tratamiento mayor de 11 semanas. El mejor valor pronóstico (0,794) lo tuvo la duración total del tratamiento mayor de 11 semanas, con un VPP de 0,928. CONCLUSIONES: Los pacientes que paran precozmente el tratamiento triple con TLV por causas diferentes a reglas de parada conservan una tasa de RVS relevante (55,9%) en esta cohorte. El ARN-VHC indetectable en semana 4 y la duración del tratamiento mayor de 11 semanas son predictivas de RVS de este subgrupo de pacientes

Impactación de un cuerpo extraño en un paciente con enfermedad de Crohn / Impacted foreign body in a patient with Crohn's disease

La enfermedad de Crohn (EC) se puede complicar con la aparición de estenosis intestinal. Las estenosis que no responden al tratamiento médico habitualmente requieren cirugía. La dilatación endoscópica con balón es una alternativa a la cirugía.A continuación se presenta el caso de un paciente con EC y una estenosis de la válvula ileocecal asintomática que se manifestó como un cuadro oclusivo secundario a la impactación de un cuerpo extraño (semilla de níspero). Se realizó una dilatación endoscópica y la extracción del cuerpo extraño. En este trabajo se lleva a cabo una revisión de la literatura médica en relación al tratamiento endoscópico de las estenosis intestinales secundarias a la EC (AU)

Crohn's disease is often complicated by intestinal strictures. Symptomatic strictures refractory to medical therapy usually require surgery. Endoscopic balloon dilatation is an alternative to surgery. We report the case of a patient with CrohnŒs disease with asymptomatic ileocecal stricture, which was identified after intestinal obstruction due to an impacted foreign body. The patient underwent endoscopic dilatation and the foreign body was extracted. We provide a review of the literature on endoscopic balloon dilatation of intestinal strictures in Crohn's disease (AU)

[Severe tubulo-interstitial nephritis secondary to 5-ASA]. / Nefropatía tubulointersticial grave secundaria a 5-ASA.

We report a new case of chronic interstitial nephritis in a patient with ulcerative colitis diagnosed in 2002 who was originally treated with 5-ASA. Three years later deterioration of renal function was apparent with an increase in serum creatinine, which was normal before treatment. Withdrawal of 5-ASA led to partial improvement of renal function. In patients with a delayed diagnosis of kidney damage, recovery of renal function is incomplete and, in some cases, the patient even requires some form of renal replacement therapy. We stress the importance of monitoring renal function in patients diagnosed with inflammatory bowel disease treated with this drug.

Nefropatía tubulointersticial grave secundaria a 5-ASA / Severe tubulo-interstitial nephritis secondary to 5-ASA

Presentamos un nuevo caso de nefritis intersticial crónica de una paciente con colitis ulcerosa diagnosticada en 2002, que desde el principio fue tratada con 5-ASA. Tres años más tarde apareció un deterioro de la función renal con un incremento de los valores de creatinina sérica, los cuales eran normales antes del tratamiento. La función renal mejoró parcialmente tras la supresión del tratamiento. En los pacientes con un retraso en el diagnóstico del daño renal, la recuperación de la función renal no es completa, e incluso, en algunos casos, el paciente necesita alguna forma de terapia de reemplazo renal. Queremos recordar la importancia del registro de la función renal en pacientes diagnosticados de enfermedad inflamatoria intestinal en tratamiento con este fármaco(AU)

[Ileal perforation secondary to intestinal endometriosis]. / Perforación ileal secundaria a endometriosis.

Endometriosis is defined as the presence of endometrial tissue outside the uterus. The bowel is not often affected. There are no specific clinical findings for intestinal endometriosis. It is typically asymptomatic, but sometimes can present with abdominal pain, diarrhoea, constipation or intestinal obstruction. Ileal perforation is a rare complication of intestinal endometriosis and only a few cases have been reported in the literature. Intestinal endometriosis can mimic many gastrointestinal diseases, such as irritable bowel syndrome, inflammatory bowel disease, infections and neoplasms. The diagnosis is made by laparoscopy or laparotomy. We present a case of a woman with intermittent abdominal pain and ileal perforation secondary to intestinal endometriosis.

Perforación ileal secundaria a endometriosis / Ileal perforation secondary to intestinal endometriosis

La endometriosis es la presencia de tejido endometrial fuera del útero. La afección del intestino por endometriosis es una entidad poco frecuente y suele ser asintomática o presentarse de forma inespecífica con dolor abdominal, diarrea, estreñimiento u obstrucción intestinal. La perforación intestinal es poco frecuente, y hay pocos casos publicados en la literatura médica. La endometriosis intestinal puede imitar a un gran número de enfermedades digestivas, como el síndrome del intestino irritable, la enfermedad inflamatoria intestinal, infecciones o neoplasias. El diagnóstico se suele realizar a través de laparoscopia o laparotomía. Presentamos el caso de una paciente con dolor abdominal recurrente y posterior perforación ileal, secundaria a endometriosis
