Octreotide long-active release in the treatment of gastrointestinal bleeding due to vascular malformations: Cost-effectiveness study.

INTRODUCTION: Gastrointestinal hemorrhage due to vascular malformations has a negative impact on patients´ quality of life and consumes an important quantity of resources. OBJECTIVE: Analyze the cost-effectiveness of long-active releasing octreotide (OCT-LAR) in the treatment of gastrointestinal haemorrhage secondary to vascular malformations. MATERIAL AND METHODS: Retrospective study, including 19 pacients that were treated with mensual injections of OCTLAR between 2008-2013. The number of blood transfusions, hemoglobin levels, hospital admissions and possible side effects during the year before treatment and the year after the start of the treatment were assessed, and cost-effectiveness was analyzed. RESULTS: After the beginning of the treatment with OCTLAR, complete response was observed in 7 patients (36.8 %), partial response in 7 patients (36.8 %) and 5 patients (26.3 %) continued to require admissions, blood transfusions and/or endoscopic treatment. We observed significant reduction in the length of admission per year (in days) before and after the start of the treatment (22.79 versus 2.01 days, p < 0.0001) as well as in the number of blood transfusions administered (11.19 versus 2.55 blood transfusions per year, p = 0.002). The mean haemoglobin levels increased from 6.9 g/dl to 10.62 g/dl (p < 0.0001). We observed reduction of costs of 61.5 % between the two periods (from 36,072.35 € to 13,867.57 € per patient and year, p = 0.01). No side effects related to treatment were described. CONCLUSION: In conclusion, OCT-LAR seems to be a costefficient and safe pharmacological treatment of gastrointestinal haemorrhage secondary to vascular malformations, mainly in patients in whom endoscopic or surgical treatment is contraindicated.

Listeria monocytogenes infection in inflammatory bowel disease patients: case series and review of the literature.

BACKGROUND: Listeria monocytogenes (LM) is a gram-positive intracellular bacillus that in immunodeficient patients, children, geriatric patients, pregnant women, and even in healthy individuals can cause central nervous system infection, bacteremia, and other clinical manifestations, becoming a relevant pathogen. MATERIALS AND METHODS: From the Microbiology Service data of 'Gregorio Marañón' Hospital, we selected all positive biological sample cultures for LM from inflammatory bowel disease (IBD) patients, from January 1986 until January 2011. These cases were included in an SPSS database, analyzing several basal clinical characteristics and factors related to the infection. RESULTS: Three patients diagnosed with IBD had positive cultures for LM during this period. All of them were male, and also all of them had a diagnosis of Crohn's disease. Every patient had a corticosteroid cumulated dose of more than 400 mg (equivalency in methylprednisolone doses), adding anti-tumor necrosis factor-α treatment (certolizumab) in one patient. Prior colonoscopy with biopsy was performed in two patients. Clinical presentation of the infection was bacteremia in two patients, accompanied by central nervous system infection in one patient. One patient had isolated meningoencephalitis. Despite correct empiric treatment, one patient died from a cause related to the infection, that is, rombencephalitis. Increased incidence of LM bacteremia was found in IBD patients, compared with the general population (12.2 bacteremias/100 000 IBD patient-years, compared with 1.6 bacteremias/100 000 person-years), with an odds ratio of 7.4. CONCLUSION: IBD patients may be at risk for more frequent and serious LM infection compared with the general population.

Octreótido de acción prolongada (LAR) en el tratamiento de hemorragia digestiva por lesiones vasculares: estudio de coste-eficiencia / Octreotide long-active release in the treatment of gastrointestinal bleeding due to vascular malformations: cost-effectiveness study

INTRODUCCIÓN: la hemorragia digestiva por lesiones vasculares (HDLV) deteriora la calidad de vida de los pacientes y requiere el consumo de una importante cantidad de recursos. OBJETIVO: analizar la coste-eficiencia de octreótido de depósito (OCT-LAR) en el tratamiento de hemorragia gastrointestinal por lesiones vasculares. MATERIAL Y MÉTODOS: estudio retrospectivo, incluyendo a 19 pacientes que fueron tratados con inyecciones mensuales de OCTLAR entre los años 2008-2013. Se revisaron los requerimientos transfusionales, niveles de hemoglobina, necesidad de ingreso hospitalario y posibles efectos secundarios en el año previo y posterior al inicio del tratamiento, se analizó la coste-eficiencia. RESULTADOS: tras el inicio de OCT-LAR observamos respuesta completa en 7 pacientes (36,8 %), parcial en otros 7 pacientes (36,8 %) y 5 pacientes (26,3 %) siguieron precisando ingresos, trasfusiones de hemoderivados y/o tratamiento endoscópico. Observamos disminución significativa de los días de ingreso al año, antes y después de tratamiento (22,79 vs. 2,01 días, p < 0,0001) y del número de concentrados de hematíes transfundidos (11,19 vs. 2,55 concentrados de hematíes por paciente/año, p = 0,002). La media de hemoglobina mejoró de 6,95 a 10,62 g/dl (p < 0,0001). Observamos una reducción del 61,5 % del coste entre los dos periodos (de 36.072,35 Euros a 13.867,57 Euros por paciente/ año, p = 0,01). No se observaron efectos secundarios asociados al tratamiento. CONCLUSIÓN: en conclusión, OCT-LAR parecer ser un tratamiento farmacológico coste-eficiente y seguro para la hemorragia digestiva secundaria a malformaciones vasculares, especialmente en pacientes no subsidiaros de tratamiento endoscópico o quirúrgico
