Interacciones fármaco-nutriente en el soporte nutricional artificial

The drug-nutrient interaction is defined as an alteration of the kinetics and/or dynamics of a medicine or nutrient, and/or the deterioration of the nutritional status caused by the administration of the drug. Kinetics refers to the quantitative description of a drug or its availability, and the dynamics characterizes the clinical or physiological effects of the drug. In order to carry out this review, a total of 21 articles cited in the PubMed database were selected and consulted together with the reports of different Spanish Society Societies' guides on clinical practice related to these interactions. They contain different types of interactions and negative effects that are induced both at the level of enteral nutrition (EN) and parenteral (NP). Therefore, the availability of nutrients can be affected by the drug and the effect of the drug can be modified by the nutrient, including the risk of adverse effects. This interaction becomes even more relevant, when we speak of artificial nutritional support, therefore, patients that require the use of enteral or parenteral nutrition, in general, are not usually subjected exclusively to this medical intervention, but it is only one more part of their pharmacological therapy, increasing the risk of interactions and causing a loss of effectiveness of the pharmacological treatment, obstruction of the feeding tube, incompatibility and destabilization of the NP emulsion, appearance of adverse reactions or alteration of the nutritional status among others. The clinical consequences, derived from this, will depend on the type of drug and the characteristics of the patient, being more susceptible chronic polymedicated patients, elderly, and in critical conditions. In conclusion, it is essential to know the main types of interactions, as well as the appropriate administration techniques, to help minimize these incompatibilities and promote the success of good pharmacotherapy.La interacción fármaco-nutriente se define como una alteración de la cinética o dinámica de un medicamento o nutriente, y/o el deterioro del estado nutricional causado por la administración del fármaco. La cinética se refiere a la descripción cuantitativa de un medicamento o su disponibilidad, y la dinámica caracteriza el efecto clínico o fisiológico de la droga. Para la realización de esta revisión se han seleccionado y consultado un total de 21 artículos citados en la base de datos PubMed junto con los informes de diferentes guías de Sociedades Científicas españolas sobre práctica clínica relacionadas con dichas interacciones. En ellos se recogen diferentes tipos de interacciones y efectos negativos que se inducen tanto a nivel de la nutrición enteral (NE) como de la parenteral (NP). La disponibilidad de nutrientes puede verse afectada por el fármaco y el efecto terapéutico del fármaco puede ser modificado por el nutriente, incluido el riesgo de efectos adversos. Esta interacción se hace aún más relevante, cuando hablamos de soporte nutricional artificial, pues, los pacientes que requieren el uso de NE o NP, por lo general, no suelen estar sometidos exclusivamente a esa intervención médica, sino que solo es una parte más de su terapia farmacológica, aumentando el riesgo de interacciones y pudiendo ocasionar una pérdida de efectividad del tratamiento farmacológico, obstrucción de la sonda, incompatibilidad y desestabilización de la emulsión de NP, aparición de reacciones adversas o alteración del estado nutricional entre otros. Las consecuencias clínicas, derivadas de ello, dependerán del tipo de fármaco y de las características del paciente, siendo más susceptibles, los pacientes crónicos polimedicados, ancianos, y en estado crítico. Se concluye en la necesidad de conocer los principales tipos de interacciones, así como las técnicas de administración adecuadas, para ayudar a minimizar estas incompatibilidades y favorecer el éxito de una buena farmacoterapia

A Multiple Stakeholder Multicriteria Decision Analysis in Diabetic Macular Edema Management: The MULTIDEX‑EMD Study

Background The clinical and economic management of retinal diseases has become more complex following the introduction of new intravitreal treatments. Multicriteria decision analysis (MCDA) offers the potential to overcome the challenges associated with traditional decision-making tools. Objectives A MCDA to determine the most relevant criteria to decision-making in the management of diabetic macular edema (DME) based on the perspectives of multiple stakeholders in Spain was developed. This MCDA was termed the MULTIDEX-EMD study. Methods Nineteen stakeholders (7 physicians, 4 pharmacists, 5 health authorities and health management experts, 1 psychologist, and 2 patient representatives) participated in this three-phase project. In phase A, an advisory board defined all of the criteria that could influence DME treatment decision-making. These criteria were then screened using a discrete choice experiment (DCE) (phase B). Next, a multinomial logit model was fitted by applying the backward elimination algorithm (relevant criteria: p value = 15 letters (p value < 0.001), effect duration per administration (p value = 0.008), retinal detachment (p value < 0.001), endophthalmitis (p value = 0.012), myocardial infarction (p value < 0.001), intravitreal hemorrhage (p value = 0.021), annual treatment cost per patient (p value = 0.001), health-related quality of life (HRQoL) (p value = 0.004), and disability level (p value = 0.021). Conclusions From a multi-stakeholder perspective, the selection of an appropriate treatment for DME patients should guarantee patient safety and maximize the visual acuity improvement and treatment effect duration. It should also contribute to system sustainability by being affordable, it should have a positive impact on HRQoL, and it should prevent disability

Cost-Analysis of Subcutaneous vs Intravenous Administration of Natalizumab Based on Patient Care Pathway in Multiple Sclerosis in Spain

Análisis de costes; Administración subcutánea; Esclerosis múltipleAnàlisi de costos; Administració subcutània; Esclerosi múltipleCost-analysis; Subcutaneous administration; Multiple sclerosisIntroduction A subcutaneous (SC) formulation of natalizumab has been recently authorised for multiple sclerosis patients. This study aimed to assess the implications of the new SC formulation, and to compare the annual treatment costs of SC versus intravenous (IV) natalizumab therapy from both the Spanish healthcare system (direct health cost) and the patient (indirect cost) perspectives. Methods A patient care pathway map and a cost-minimisation analysis were developed to estimate SC and IV natalizumab annual costs over a 2-year time horizon. Considering the patient care pathway and according to natalizumab experience (IV) or estimation (SC), a national expert panel involving neurologists, pharmacists, and nurses provided information/data regarding resource consumption for drug and patient preparation, administration, and documentation. One hour of observation was applied to the first six (SC) or 12 (IV) doses, and 5 min for successive doses. The Day hospital (infusion suite) facilities at a reference hospital were considered for IV administrations and the first six SC injections. For successive SC injections, either a reference hospital or regional hospital in a consulting room was considered. Productivity time associated with travel (56 min to reference hospital, 24 min to regional hospital) and waiting time pre- and post-treatment (SC 15 min, IV 25 min) were assessed for patients and caregivers (accompanying 20% of SC and 35% of IV administrations). National salaries for healthcare professionals were used for cost estimation (€, year 2021). Results At years 1 and 2, total time and cost savings (excluding drug acquisition cost) per patient, driven by saving on administration and patient and caregiver productivity for SC at a reference hospital versus IV at a reference hospital, were 116 h (a reduction of 54.6%) and €3682.82 (a reduction of 66.2%). In the case of natalizumab SC at a regional hospital, the total time and cost saving were 129 h (a reduction of 60.6%) and €3883.47 (a reduction of 69.8%). Conclusions Besides the potential benefits of convenient administration and improving work–life balance, as suggested by the expert panel, natalizumab SC was associated with cost savings for the healthcare system by avoiding drug preparation, reducing administration time, and freeing up infusion suite capacity. Additional cost savings could be derived with regional hospital administration of natalizumab SC by reducing productivity loss

Pasado y futuro de la infección por VIH. Un documento basado en la opinión de expertos

[EN] HIV infection is now almost 40 years old. In this time, along with the catastrophe and tragedy that it has entailed, it has also represented the capacity of modern society to take on a challenge of this magnitude and to transform an almost uniformly lethal disease into a chronic illness, compatible with a practically normal personal and relationship life. This anniversary seemed an ideal moment to pause and reflect on the future of HIV infection, the challenges that remain to be addressed and the prospects for the immediate future. This reflection has to go beyond merely technical approaches, by specialized professionals, to also address social and ethical aspects. For this reason, the Health Sciences Foundation convened a group of experts in different aspects of this disease to discuss a series of questions that seemed pertinent to all those present. Each question was presented by one of the participants and discussed by the group. The document we offer is the result of this reflection. [ES] La infección por VIH cumple ahora casi 40 años de existencia. En este tiempo, junto a la catástrofe y la tragedia que ha supuesto, ha representado también la capacidad de la sociedad moderna de asumir un reto de esta magnitud y de transformar, gracias al tratamiento antirretroviral, una enfermedad mayoritariamente letal en una enfermedad crónica, compatible con una vida personal y de relación prácticamente normales. Este aniversario parecía un momento idóneo para pararse a reflexionar sobre el futuro de la infección VIH, los retos que todavía quedan por abordar y las perspectivas para el inmediato futuro. Esa reflexión tiene que ir más allá de planteamientos meramente técnicos, de profesionales especializados, para abordar aspectos sociales y éticos. Por este motivo, la Fundación de Ciencias de la Salud convocó a un grupo de expertos en distintos aspectos de esta infección para discutir una serie de preguntas que parecieron pertinentes a todos los convocados. Cada pregunta era expuesta por uno de los participantes y discutida por el grupo. El documento que ofrecemos es el resultado de esa reflexión.For transparency purposes, we would like to inform you that GSK has contributed to the funding of this publication.

Next, a multinomial logit model was ftted by applying the backward elimination algorithm (relevant criteria: p value<0.05). Finally, the results were discussed in a deliberative process (phase C). Results Thirty-one criteria were initially defned (phase A) and grouped into 5 categories: efcacy/efectiveness, safety, organizational and economic impact, patient-reported outcomes, and other therapeutic features. The DCE results (phase B) showed that 10 criteria were relevant to the decision-making process for a 50- to 65-year-old DME patient: mean change in best corrected visual acuity (p value<0.001), percentage of patients with an improvement of ≥15 letters (p value<0.001), efect duration per administration (p value=0.008), retinal detachment (p value<0.001), endophthalmitis (p value=0.012), myocardial infarction (p value<0.001), intravitreal hemorrhage (p value=0.021), annual treatment cost per patient (p value=0.001), health-related quality of life (HRQoL) (p value=0.004), and disability level (p value=0.021). Conclusions From a multi-stakeholder perspective, the selection of an appropriate treatment for DME patients should guarantee patient safety and maximize the visual acuity improvement and treatment efect duration. It should also contribute to system sustainability by being afordable, it should have a positive impact on HRQoL, and it should prevent disability

A study of anthropometric, biochemical and nutritional parameters in adolescents in the area of Toledo, Spain.

Background. An incrementation of risk of cardiovascular disease (CVD) in the younger population has been reported in Spain. Adolescents have changed their dietary habits and increased the risk of metabolic syndrome (MS). The Longitudinal study in the area of Toledo aims to evaluate food intake and nutritional habits and their relationship with early development of CVD and insulin resistance/sensitivity biomarkers.Methods. A cross-sectional study was performed on 53 adolescents aged 16-17 years belonging to the Area of Toledo. Energy, macronutrient and micronutrient intakes and diet quality were assessed, as well as the prevalence to being overweight, the presence of CVD risk factors and parameters related to glucose homeostasis to identify candidates for MS.Results. Adolescents consumed monotonous diets, with low Mediterranean diet Adherence (MDA) and Health Eating Index (HEI) scores and with elevated energy contribution of saturated fatty acids and low carbohydrates. Being overweight but not obese was moderately prevalent in volunteers. However, a low percentage of them showed dyslipemia or insulin resistance. No significant differences between male and female adolescents were found for any dietary parameter tested. HEI and MDA scores appear inversely related to insulin resistance markers in boys and to fat mass in girls, respectively.Conclusions. The high similitude of diet in both male and female subjects suggests a general adherence to potentially negative dietary habits in this population. Paradoxically, dietary components and altered lipoprotein factors were not related. The prevalence to being overweight, the association between diet quality and MS-markers found demands a follow-up study to ascertain the importance of present results later in life
