Multizonal observational study conducted by clinical practitioners on Repatha® use in patients with hyperlipidemia (ZERBINI): Colombian results / Estudio Observacional Multizonal realizado por Médicos Clínicos sobre el Uso de Repatha® en Pacientes con Hiperlipidemia (ZERBINI): resultados colombianos

Background Cardiovascular disease (CVD) represents the primary cause of death and disability globally, with elevated cholesterol as one of the leading risk factors for CVD. We describe the clinical characteristics, treatment patterns, and effectiveness of evolocumab in treating hyperlipidemia. Methods Observational study conducted through a chart review of patients with hyperlipidemia receiving evolocumab as part of clinical management in Colombia. Results This study included 115 patients treated with evolocumab. A total of 101 patients (87.8%) had a history of CVD, 13 (11.3%) familial hypercholesterolemia (FH), and 23 (20%) type 2 diabetes. Thirty-nine patients reported intolerance to any statin (33.9%). The median value of LDL-C before initiation of evolocumab was 147mg/dL (IQR: 122.5–183.7mg/dL). Within the first 3 months of treatment, LDL-C value dropped to a median value of 53mg/dL (IQR: 34.0–95.5mg/dL), showing a reduction of 63.9%. The median LDL-C values remained below 45mg/dL until the end of follow-up. Among the patients with available data, up to 61% achieved an LDL-C level below 55mg/dL at the 10–12-month follow-up. A total of 72% of patients were persistent with treatment. Safety results showed a low frequency of hospitalizations (≤2%) and treatment-emergent adverse drug reactions (5.2%). No serious adverse events were reported. Conclusions Evolocumab was associated with reductions in LDL-C levels, with a relative decrease of 63.9% within the first 3 months of treatment. Low rates of interruptions due to adverse events and adequate medication persistence was reported. (AU)

Real-World Insights Into Evolocumab Use in Patients With Hyperlipidemia: Canadian Analysis From the ZERBINI Study.

Background: The 2021 Canadian Cardiovascular Society guidelines recommend proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitor therapy in patients with atherosclerotic cardiovascular disease whose low-density lipoprotein cholesterol (LDL-C) concentration remains ≥ 1.8 mmol/L despite maximally tolerated statin therapy. This retrospective and prospective observational study characterizes Canadian patients treated with evolocumab and describes its effectiveness and safety. Methods: Between August 2017 and July 2019, a total of 131 patients initiated on evolocumab therapy were enrolled at 15 sites in Canada. Data were extracted from medical records every 3 months between 6 months prior to, and for 12 months following evolocumab therapy initiation, until July 6, 2020. Baseline and prospectively collected data are reported as available. Results: A total of 131 patients were enrolled (59.5% male; mean age [standard deviation (SD)] 64.7 ± 10.6 years), most with a diagnosis of atherosclerotic cardiovascular disease and/or familial hypercholesterolemia (93.4%). Mean (± SD) LDL-C concentration at baseline was 3.7 (± 1.7) mmol/L (n = 119), with 58.0% of patients receiving a statin (36.6% high intensity). Mean (± SD) LDL-C concentration after evolocumab treatment was 1.6 (± 1.0) mmol/L (n = 120), representing a 58.7% decrease from baseline (n = 109). This level remained stable over 12 months. An LDL-C concentration < 1.8 mmol/L was achieved by 77.5% of patients. Persistence was 92%, and no serious treatment-emergent adverse events were reported. Conclusions: These findings provide real-world evidence of guideline-recommended initiation of evolocumab therapy, as well as confirmation of its effectiveness and safety in a Canadian population. Evolocumab therapy can address a healthcare gap in the management of dyslipidemia, by increasing the proportion of patients achieving LDL-C goals recommended to lower cardiovascular risk.

Introduction: Les lignes directrices de la Société canadienne de cardiologie de 2021 recommandent un traitement par les inhibiteurs de proprotéine convertase subtilisine-kexine de type 9 (PCSK9) aux patients atteints de la maladie cardiovasculaire athérosclérotique chez lesquels les concentrations de cholestérol à lipoprotéines de faible densité (cholestérol LDL) demeurent ≥ 1,8 mmol/l malgré le traitement maximalement toléré par statines. La présente étude observationnelle rétrospective et prospective donne les caractéristiques des patients canadiens traités par évolocumab, et décrit l'efficacité et l'innocuité de ce médicament. Méthodes: Entre août 2017 et juillet 2019, nous avons inscrit un total de 131 patients qui avaient amorcé le traitement d'évolocumab dans 15 établissements du Canada. Nous avons extrait les données des dossiers médicaux tous les trois mois de six mois avant et jusqu'à 12 mois après le début du traitement par évolocumab, et ce, jusqu'au 6 juillet 2020. Les données initiales et les données collectées de façon prospective sont déclarées selon leur disponibilité. Résultats: Nous avons inscrit un total de 131 patients (59,5 % d'hommes; âge moyen [écart type (ET)] 64,7 ± 10,6 ans); la plupart avaient un diagnostic de maladie cardiovasculaire athérosclérotique et/ou d'hypercholestérolémie familiale (93,4 %). Les concentrations initiales moyennes (± ET) de cholestérol LDL étaient de 3,7 (± 1,7) mmol/l (n = 119), et 58,0 % des patients recevaient une statine (36,6 % d'intensité élevée). Les concentrations moyennes (± ET) de cholestérol LDL après le traitement par évolocumab étaient de 1,6 (± 1,0) mmol/l (n = 120), soit une diminution de 58,7 % par rapport aux concentrations initiales (n = 109). Ces concentrations sont demeurées stables durant 12 mois. Des concentrations de cholestérol LDL < 1,8 mmol/l ont été atteintes par 77,5 % des patients. La persistance a été de 92 %, et aucun événement défavorable sérieux associé au traitement n'a été déclaré. Conclusions: Ces résultats fournissent des données probantes du monde réel sur l'amorce du traitement par évolocumab conformément aux recommandations des lignes directrices, ainsi qu'une confirmation de son efficacité et de son innocuité au sein d'une population canadienne. Le traitement par évolocumab peut permettre de remédier aux lacunes des soins de santé dans la prise en charge de la dyslipidémie par l'augmentation de la proportion de patients atteignant les objectifs recommandés en matière de cholestérol LDL pour réduire le risque de maladies cardiovasculaires.

Evaluación de la seguridad de la CPRE en pacientes de la tercera edad: experiencia de un hospital universitario en Bogotá / Evaluation of the Safety of ERCP in Older Patients in the Experience of a University Hospital in Bogota

Antecedentes: la colangiopancreatografía retrógrada endoscópica (CPRE) es el método de elección en el manejo de la coledocolitiasis; sin embargo, existen controversias sobre su seguridad en el adulto mayor. Objetivo: determinar si hay mayor riesgo de complicaciones con la realización de la CPRE en el manejo de la coledocolitiasis en pacientes mayores de 70 años de edad valorados en el Hospital Universitario Clínica San Rafael (HUCSR). Metodología: se realizó un estudio analítico de corte transversal que incluyó pacientes que ingresaron al servicio de urgencias del HUCSR durante el período de 1 año (2011-2012) con diagnóstico de coledocolitiasis. La información demográfica, clínica y paraclínica, así como los hallazgos del procedimiento, fueron analizados teniendo en cuenta dos grupos de pacientes (mayores y menores de 70 años de edad). Se llevó a cabo un análisis estadístico univariado y bivariado. Resultados: se incluyó un total de 171 pacientes. La presencia de comorbilidades (es decir, diabetes e hipertensión arterial), los niveles de bilirrubina directa y de transaminasas fueron variables asociadas significativamente con los pacientes con edad mayor o igual a los 70 años. Se presentaron complicaciones relacionadas con el procedimiento, siendo la más frecuente la pancreatitis pos-CPRE y la hemorragia pospapilotomía; sin embargo, no estuvieron relacionadas con la edad de los pacientes. Conclusión: la CPRE es segura en pacientes con coledocolitiasis. La edad mayor de 70 años no incrementa la mortalidad relacionada con el procedimiento.

Background: Although endoscopic retrograde cholangiopancreatography (ERCP) is the method of choice for management of choledocholithiasis, there are still controversies about its safety for elderly patients. Objective: To determine whether there is increased risk of complications from ERCP in the management of choledocholithiasis in patients over 70 years valued at University Hospital Clínica San Rafael (HUCSR). Methodology: A cross-sectional analytical study that included patients admitted to the emergency department of HUCSR during the period of one year (2011-2012) with a diagnosis of choledocholithiasis was performed. The demographic, clinical and paraclinical findings and procedure were analyzed taking into account two groups of patients (older and younger than 70 years). Univariate statistical analysis was performed and bivariate. Results: A total of 171 patients were included. The presence of comorbidities (eg, diabetes and hypertension), the levels of direct bilirubin and transaminases were variables significantly associated with patients with greater than or equal to 70 years old. Procedure-related complications were presented the most frequent post-ERCP pancreatitis and post papilotomy bleeding; however, were not related to patient age. Conclusion: ERCP is safe in patients with choledocholithiasis. Age over 70 years does not increase the mortality associated with the procedure.

Bacterial translocation in abdominal trauma and postoperative infections.

BACKGROUND: Bacterial translocation (BT) describes the passage of bacteria residing into the gastrointestinal tract, through the intestinal mucosa barrier to sterile tissues such as mesenteric lymph nodes (MLN) and other organs. This phenomenon has not been thoroughly studied in patients with trauma to date, and an association between BT and postoperative infection has not been well established so far. METHODS: MLNs from 36 patients with abdominal trauma were removed during laparotomy and cultured to detect BT. Postoperative infectious complications in these patients were registered, and both phenotypical and molecular typings (through multilocus sequencing) were carried out for microorganisms isolated from MLN and postoperative infection sites. Associations between clinical variables, BT presence, and postoperative infection development were established. RESULTS: BT was detected in 33% of the patients (n = 12). Postoperative infections were present in 22.2% of the patients (n = 8). A significant statistical difference was found between postoperative infections in patients with BT evidence (41.6%), when compared with patients without BT (12.5%; p = 0.047). Bacteria isolated from infection sites were the same as those cultured in MLN in 40% of the cases (n = 2 of 5), allowing us to establish causality between BT and postoperative infection. CONCLUSIONS: There is higher risk of BT in trauma patients, and it is associated with a significant increase of postoperative infections. An abdominal trauma index ≥10 was found to be associated with the development of BT. This is the first study describing BT among patients with abdominal trauma, where causality is confirmed at molecular level.
