Evaluación de la eficacia y la seguridad de un protocolo de manejo de pacientes con diabetes descompensada por glucocorticoides durante la hospitalización / Assessment of the efficacy and safety of a protocol to manage glucocorticoid-induced hyperglycemia in diabetic patients during hospital stay

Introducción: No existen protocolos consensuados de manejo hospitalario de las descompensaciones hiperglucémicas inducidas por dosis farmacológicas de glucocorticoides (GC). Nuestro objetivo fue evaluar la eficacia y la seguridad de un protocolo de insulinización específico para corticoides (PC) frente a un protocolo general (PG) en diabetes descompensada por GC (DDG). Materiales y métodos: Estudio experimental con grupo control, no aleatorizado, en pacientes con DDG ingresados en neumología. Se compararon 2 protocolos (PC y PG), ambos basados en terapia basal-bolo pero con diferentes dosis y distribución de insulina. Se evaluó la diferencia de glucemia media (GM) durante la hospitalización entre el PC y el PG, así como el riesgo de presentar una GM > 200mg/dl, ajustado para potenciales factores de confusión (relacionados con el paciente y con la terapia de GC empleada). Resultados: Se incluyó a 131 pacientes, 60 asignados al PG y 71 al PC. Un 74% de los pacientes estaban ingresados por exacerbación de enfermedad pulmonar obstructiva crónica. Hubo diferencia significativa en la dosis total de insulina entre el PG y el PC (29,4 vs. 57,4 unidades; p < 0,0001). La diferencia ajustada de GM (PC-PG) fue de -14,8 (IC del 95%, -26,2 a -3,3) mg/dl. Los pacientes del PC tuvieron menor riesgo ajustado de presentar GM > 200mg/dl durante la hospitalización (OR = 0,31; IC del 95%, 0,11-0,91; p = 0,033). No hubo diferencias en el riesgo de hipoglucemia grave entre el PG y el PC (0% vs. 1,4%; p = 0,36). Conclusiones: El protocolo estudiado ha demostrado reducir la GM de pacientes con DDG durante la hospitalización sin comprometer su seguridad

Introduction: There are no agreed protocols on hospital management of hyperglycemic decompensation induced by pharmacological doses of glucocorticoids (GCs). The study objective was to assess the efficacy and safety of an insulin therapy protocol specific for patients treated with glucocorticoids (CP) as compared to a general protocol (GP) in diabetes decompensation secondary to glucocorticoids. Materials and methods: An experimental study in patients with glucocorticoids-induced decompensated diabetes admitted to a respiratory ward including a non-randomized control group. Two protocols (CP and GP), both based on basal-bolo insulin regimens, but with different insulin doses and distribution, were compared. The difference in mean blood glucose (MBG) levels between both protocols was measured during hospital stay, as was the risk of having MBG levels > 200mg/dL, adjusted for potential confounding factors (related to patients and to the glucocorticoid therapy used). Results: A total of 131 patients were included, 60 assigned to the GP and 71 to the CP groups. Seventy-four percent of patients had been admitted due to COPD exacerbation. There was a significant difference in the total daily insulin dose used between the CP and GP groups (29.4 vs. 57.4 IU; P<.0001). The adjusted difference in MBG levels (CP-GP) was -14.8 (95% CI, -26.2 to -3.3) mg/dL. Patients in the CP group had a lower adjusted risk of having MBG levels >200mg/dL during hospital admission (OR=0.31; 95% CI, 0.11-0.91; P=.033). There were no differences in the risk of severe hypoglycemia between the CP and GP groups (0% vs. 1.4%; P=.36). Conclusions: The study protocol has been shown to decrease MBG levels in patients with glucocorticoids-induced decompensation of diabetes during hospital admission without compromising their safety

Mortality risk factors after percutaneous gastrostomy: Who is a good candidate?

BACKGROUND: The percutaneous gastrostomy tube (PG) is an effective and safe way for the delivery of enteral nutrition. The aim of this study was to identify predictive factors for mortality after PG placement. MATERIAL AND METHODS: An observational and analytical cohort study was conducted. All endoscopic or radiological percutaneous gastrostomy tubes placed between January 2009 and July 2016 were evaluated. Mortality was the dependent variable. Initial clinical and analytical patient features and the development of complications during follow-up were recorded. Cox regression models were used to evaluate the risk of mortality associated to the studied variables. Hazard ratios with the corresponding 95% confidence intervals were retrieved from these models. RESULTS: A total of 289 patients underwent PG placement (57% male). The mean age was 70.1 (SD 13.6) years. The median follow-up period was 8.7 (IQR 18) months. One hundred and seventy-four patients died during the follow-up period. The overall mortality rate was 4.8 per 100 patients-month. The highest mortality rate was during the first month after PG placement (13.2 per 100 patients-month), subsequently decreasing. Multivariate regression analysis showed that age (HR1year = 1.01; p = 0.015), Charlson comorbidity index ≥4 (HR = 1.69; p = 0.011), the presence of degenerative neurological disease (HR = 1.69; p = 0.012) or malignancy (HR = 2.02; p = 0.012) and the development of aspiration pneumonia during the follow-up period (HR = 3.29; p = 0.001) were statistically significant independent predictive risk factors associated with mortality. A model to predict survival probability prior to placing the PG was developed from the variables of the multivariate analysis. CONCLUSION: Mortality after PG placement is high. Older age, higher comorbidity and the development of aspiration pneumonia are predictive factors for mortality. A more careful selection of candidates for PG placement should be done to improve the patient prognosis after the procedure.

Predictive factors of hypertriglyceridemia in inhospital patients during total parenteral nutrition / Factores predictores de hipertrigliceridemia en pacientes hospitalizados con nutrición parenteral total

Introduction: Total parenteral nutrition (TPN) is a kind of nutritional support indicated for patients whose clinical situation makes it impossible to cover their nutritional requirements enterally. Despite the fact that TPN is a safe and effective therapy, some complications have been described. One of the most frequent is hypertriglyceridemia. The etiology of this metabolic complication is complex and multifactorial. Objetive: The aim of this work was to determine risk factors associated with the development of hypertrilgyceridemia in adult inhospital non critical patients who carry TPN for a short term. A secondary aim was to evaluate the effect that a lipid emulsion fortified with omega-3 poliunsaturated fatty acids causes on this metabolic complication. Material and methods: This is an observational retrospective cohort study, in which adult inhospital non critical patients have been included. Only those who needed TPN during more than seven days were included. Hypertriglyceridemia was defined as plasma triglycerides levels higher than 200 mg/dl. The lipid emulsions were composed whether by a combination of 50% long-chain (LCT) and medium-chain (MCT) triglycerides or 40% LCT/50% MCT/10% omega-3. Clinical, nutritonal and biochemical parameters were included. Analitical samples were obtained before starting TPN, and weekly until withdrawal. Multivariate logistic regression analysis was used to identify predictive factors of the appearance of hypertriglyceridemia. Results: One hundred and one patients were included (61.4% male). Thirty-three per cent of them developed hypertriglyceridemia. In the multivariate analysis the independent risk factors associated with the presence of hypertriglyceridemia were the initial plasmatic triglycerides levels, the body mass index (BMI) and an input of glucose in the TPN higher than 3.1 g/kg/day. The infusion of a lipid emulsion fortified with 3-omega fatty acids was associated with a nonsignificant reduction of the risk of appearance of hypertriglyceridemia. Conclusion: The patient's clinical metabolic situation, as well as the load of carbohydrates in the TPN are essential for the development of the TPN-associated hypertriglyceridemia. The administration of a lipid emulsion fortified with omega-3 fatty acids is safe, even though it was not associated with a signifi cant protective effect over the risk of appearance of this metabolic complication.

Introducción: la nutrición parenteral total (NPT) es una modalidad de soporte nutricional indicada en aquellas situaciones donde el enfermo no puede cubrir sus requerimientos nutricionales por vía enteral. A pesar de ser una terapia segura y eficaz, no está exenta de complicaciones, entre las que cabe destacar, por su frecuencia, la hipertrigliceridemia. La etiología de esta complicación metabólica es compleja y multifactorial. Objetivos: el objetivo de este trabajo fue determinar los factores de riesgo asociados al desarrollo de hipertrigliceridemia en pacientes adultos hospitalizados no críticos que reciben NPT a corto plazo y evaluar el efecto que una emulsión lipídica enriquecida en ácidos grasos poliinsaturados omega-3 ejerce sobre esta complicación metabólica. Material y métodos: estudio observacional retrospectivo de cohortes donde se ha incluido a pacientes hospitalizados adultos no críticos que precisaron NPT durante un periodo superior a siete días. Se consideró la presencia de hipertrigliceridemia cuando los niveles plasmáticos de triglicéridos fueron superiores a 200 mg/dl. Las emulsiones lipídicas empleadas fueron una mezcla al 50% de triglicéridos de cadena larga (LCT) y de cadena media (MCT) o una combinación al 40% LCT/50% MCT/10% omega-3. Se recogieron variables clínicas, nutricionales y bioquímicas. Las determinaciones analíticas se realizaron antes del comienzo de la NPT y semanalmente hasta su retirada. Los factores predictores de la aparición de hipertrigliceridemia fueron identificados mediante modelos de regresión logística multivariante. Resultados: fueron incluidos 101 pacientes (61,4% varones), de los cuales el 33% desarrolló hipertrigliceridemia. En el análisis multivariante los factores de riesgo independientes asociados a la presencia de hipertrigliceridemia fueron los niveles plasmáticos iniciales de triglicéridos, el índice de masa corporal (IMC) y un aporte de glucosa en la NPT superior a 3,1 g/kg/día. La infusión de una emulsión lipídica enriquecida con ácidos grasos omega-3 se asoció con un descenso no significativo del riesgo de aparición de hipertrigliceridemia. Conclusión: la situación clínica metabólica del paciente y la dosis de hidratos de carbono en la NPT resultan fundamentales en el desarrollo de la hipertrigliceridemia relacionada con la NPT. La administración de una emulsión lipídica enriquecida en ácidos grasos omega-3 es segura, aunque no se asoció a un efecto protector significativo sobre el riesgo de aparición de esta complicación metabólica.
