Inhibitory Effects of Varespladib, CP471474, and Their Potential Synergistic Activity on Bothrops asper and Crotalus durissus cumanensis Venoms.

Snakebite is a neglected tropical disease that causes extensive mortality and morbidity in rural communities. Antivenim sera are the currently approved therapy for snake bites; however, they have some therapeutic limitations that have been extensively documented. Recently, small molecule toxin inhibitors have received significant attention as potential alternatives or co-adjuvant to immunoglobulin-based snakebite therapies. Thus, in this study, we evaluated the inhibitory effects of the phospholipase A2 inhibitor varespladib and the metalloproteinase inhibitor CP471474 and their synergistic effects on the lethal, edema-forming, hemorrhagic, and myotoxic activities of Bothrops asper and Crotalus durissus cumanensis venoms from Colombia. Except for the preincubation assay of the lethal activity with B. asper venom, the mixture showed the best inhibitory activity. Nevertheless, the mix did not display statistically significant differences to varespladib and CP471474 used separately in all assays. In preincubation assays, varespladib showed the best inhibitory activity against the lethal effect induced by B. asper venom. However, in independent injection assays, the mix of the compounds partially inhibited the lethal activity of both venoms (50%). In addition, in the assays to test the inhibition of edema-forming activity, the mixture exhibited the best inhibitory activity, followed by Varespladib, but without statistically significant differences (p > 0.05). The combination also decreased the myotoxic activity of evaluated venoms. In these assays, the mix showed statistical differences regarding CP471474 (p < 0.05). The mixture also abolished the hemorrhagic activity of B. asper venom in preincubation assays, with no statistical differences to CP471474. Finally, the mixture showed inhibition in studies with independent administration in a time-dependent manner. To propose a mode of action of varespladib and CP471474, molecular docking was performed. PLA2s and SVMPs from tested venoms were used as targets. In all cases, our molecular modeling results suggested that inhibitors may occupy the substrate-binding cleft of the enzymes, which was supported by specific interaction with amino acids from the active site, such as His48 for PLA2s and Glu143 for the metalloproteinase. In addition, varespladib and CP471474 also showed interaction with residues from the hydrophobic channel in PLA2s and substrate binding subsites in the SVMP. Our results suggest a synergistic action of the mixed inhibitors and show the potential of varespladib, CP471474, and their mixture to generate new treatments for snakebite envenoming with application in the field or as antivenom co-adjuvants.

Tako-tsubo cardiomyopathy in clinical toxinology: A systematic review.

Tako-tsubo cardiomyopathy (TTC) is a transient left ventricular dysfunction, normally triggered by emotional or physical stress, although it is also associated with to use of drugs, drug abuse, or some intoxications. In addition, TTC has been reported in some case reports derived from the exposure of patients to animal venoms, toxins or poisons, or bacterial infections. However, to date, a systematic assessment of TTC in clinical toxinology is lacking. Therefore the aim of this study was to collect and integrate the available information about TTC in clinical toxinology. After our search strategy, 19 articles were retrieved, resulting in 20 case reports. Most cases occurred in women (75.0%). The venomous species that trigger TTC are bee/wasp, including probable Africanized honey bee and Vespa orientalis (15.0%), scorpions (Tytius serrulatus and Androctonus australis, 15.0%), a spider (Latrodectus tredecimguttatus, 5.0%), snakes (Gloydius blomhofii and Naja nivea, 10.0%), Clostridium sp (C. tetani, C. botulinum and C. difficile, 45.0%) and jellyfish (Pelagia noctiluca and Carukia barnesi, 10.0%). Among the affected people there were two deaths. In all case reports authors diagnosed TTC by using the combination of some of the following strategies: clinical findings, echocardiography, magnetic cardiac resonance, electrocardiogram changes and/or the increased plasma levels of cardiac damage biomarkers. In most cases images were available. We hypothesized the possible mode of action of venoms, toxins or poisons to induce TTC, however other mechanisms may exist, but they have not been described yet. Therefore, further studies are needed. In some cases, venoms, toxins, or poisons might cause catecholamine discharge either directly or indirectly, therefore, this was suggested as the trigger of TTC. Finally, the appearance of TTC should be considered in clinical toxinology.

Effect and associated factors of a clinical pharmacy model in the incidence of medication errors in the hospital Pablo Tobón Uribe eacpharmodel study: stepped wedge randomized controlled Trial (NCT03338725).

Background The World Health Organization considers medication errors to be an issue that requires attention at all levels of care, to reduce the severe and preventable harm related to drug therapy. Different standards for clinical pharmaceutical practices have been proposed by various organizations across the world, where the pharmacist, as part of the multidisciplinary health team, can help improve patient safety. Objective To assess the impact of the introduction of a clinical pharmacy practice model on medication error in patients of a university hospital. Setting The study was conducted in a tertiary care hospital, Medellín, Colombia. Methods A randomized, controlled cluster-wedge staggered trial with a duration of 14 months was conducted to compare the clinical pharmacy practice model with the usual care process in the hospital. Five hospital health care units were included, which were initially assigned to the control group, and after an observation period of 2 months, they were randomly assigned to the intervention group. The trial protocol was registered in ClinicalTrials.gov (identifier NCT03338725). Main outcome measure The incidence of medication errors in hospitalized patients was the main outcome measure. Results The incidence of medication error was 13.3% and 22.8% for the intervention group and control group, respectively. The probability of presenting a medication error was 48% lower when the patient was in the intervention group (RR 0.52; 95% CI: 0.34-0.79). The probability of presenting a medication error over time was 44% lower in the intervention group (p = 0.0005); meanwhile, the resolution of a medication error over time was 70% higher in the intervention group (p = 0. 0029). Conclusion The clinical pharmacy practice model, made up of strategies focused on reducing medication errors, significantly reduces medication errors in patients during hospitalization compared with usual practice. This work assessed the effect of a clinical pharmacy model on the incidence of medication errors and demonstrated its effectiveness in reducing these errors in hospitalized patients. Trial registration ClinicalTrials.gov, NCT03338725. Registered on 9 November 2017. First patient randomized on February 2, 2018.

[Pharmacist´s contribution on antimicrobial stewardship program: ambispective cohort study]. / Contribución del químico farmacéutico en los programas de gerenciamiento de antimicrobianos: estudio de cohortes ambispectivo.

BACKGROUND: Antimicrobial stewardship program (AMSP) promotes the rational use of the antimicrobial, ensuring that each patient receives the correct antibiotic, by the correct time and at the correct dose. AIM: To establish the association of the results of an AMSP led by a pharmaceutical chemist, in terms of antibiotic consumption, duration of treatment and costs in a tertiary healthcare setting. METHOD: Ambispective cohort study. In the exposed cohort, in the environment of a AMSP, a pharmacist with training in infectious diseases evaluated and intervened the indication, dosage, duration of treatment and bacterial spectrum of the antimicrobial. The no-exposed cohort corresponded to a retrospective population that was similar (paired) to the exposed cohort, but that did not receive an evaluation of its antimicrobial therapy. RESULT: 258 patients were identified in the exposed cohort and 247 in the cohort not exposed to the AMSP. Decrease in the consumption of antibiotics was observed (119,831 vs 137,678 DDD/100 patients-day, p < 0.001) and a decrease in 34.1% of the costs associated with antibiotic therapy of the exposed cohort, in comparison with the cohort not exposed to the AMSP. CONCLUSION: AMSP led by a pharmacist have better outcomes in terms of consumption and lower costs associated with antibiotic therapy.

INTRODUCCIÓN: El programa de gerenciamiento de antimicrobianos (PGAn) promueve el uso racional de los antimicrobianos, garantizando que cada paciente reciba el fármaco correcto, por el tiempo correcto, por la vía y a la dosis correcta. OBJETIVO: Establecer la asociación de los resultados de un PGAn liderado por un químico farmacéutico, en términos de consumo de antimicrobianos, duración del tratamiento y costos, en una institución prestadora de salud de alta complejidad. MATERIALES Y MÉTODO: Estudio de cohortes ambispectivo. En la cohorte expuesta, (entorno de un PGAn), un químico farmacéutico con entrenamiento en enfermedades infecciosas evaluó e intervino la indicación, dosis, duración del tratamiento y espectro bacteriano del antimicrobiano. La cohorte no expuesta fue una población retrospectiva similar (pareada) a la cohorte expuesta, pero sin la evaluación de su terapia antimicrobiana. RESULTADOS: Se identificaron 258 pacientes en la cohorte expuesta y 247 en la cohorte no expuesta al PGAn. Se observó una disminución en el consumo de antimicrobianos (119.831 vs 137.678 DDD/100 pacientes-día, p < 0,001) y una disminución de 34,1% en los costos asociados a la antibioticoterapia de la cohorte expuesta, en comparación con la cohorte no expuesta al PGAn. CONCLUSIÓN: El PGAn liderado por un químico farmacéutico se asocia a mejores resultados en términos de consumo y menores costos de la terapia antimicrobiana.

CONCLUSION: AMSP led by a pharmacist have better outcomes in terms of consumption and lower costs associated with antibiotic therapy.

[Medication errors in pediatrics]. / Errores de medicación en pediatría.

INTRODUCTION: Medication errors (ME) are preventable incidents of inappropriate use of medications by health per sonnel or by the patient. These events can occur at any stage of drug use generating significant costs to the health system and, in some cases, these can even lead to death. The pediatric population is con sidered susceptible to ME with a prevalence 3 times higher than adult patients. OBJECTIVE: To identify the prevalence of medication errors in hospitalized pediatric patients, as well as their classification according to the stage of use of the medication when they occurred. METHOD: A literature review of ME in pediatrics was carried out through a Pubmed / Medline search using Mesh terms ("Medication Errors" and "Pediatrics") in the last 10 years. Three investigators reviewed independently the identi fied articles considering the STROBE checklist for observational studies. RESULTS: 192 bibliographic references were identified, 22 of them were eligible for review and data collection. Studies reported an error rate between 1% and 58% of the evaluated medication indications, with errors reported in different processes of drug use. 9 articles (41%) described errors related only to prescription, mainly associated with incorrect dosage, 6 (27%) errors related to prescription, administration, and other processes, 3 (14%) related to prescription and administration, 2 (9%) related only to administra tion, 1 (4%) article reported errors related to conciliation, and 1 (4%) described errors related to preparation and administration. CONCLUSION: The studies reported different medication errors in the pediatric population. Most of them reported ME related to prescription followed by ME in the administration. Knowing the proportion of ME allows focusing interventions aimed at reducing their prevalence.

COVID-19 in Colombia endpoints. Are we different, like Europe?

The infection by the new coronavirus (SARS-CoV-2) has taken the dimension of a pandemic, affecting more than 160 countries in a few weeks. In Colombia, despite the implementation of the rules established by the national government, exists an elevate concern both for mortality and for the limited capacity of the health system to respond effectively to the needs of patients infected. For Colombia, assuming a case fatality rate among people infected with SARS-CoV-2 of 0.6% (average data from the information reported for Latin American countries for March 18) (Table 1), the number of deaths, in one or two weeks, could be 16 and 243, respectively. These estimates differ markedly from those documented in countries such as Spain and Italy, in which COVID-19 case fatality rates exceed 8% (case of Italy) and from the percentage of patients who have required intensive care, which has ranged from 9% to 11% of patients in Mediterranean European countries. These differences could be explained due to: a) the percentage of the population at risk (individuals older than 60 years); b) a higher epidemiological exposure to viral respiratory infections associated with more frequent exposure to them, due to geographic and climatic conditions; c) less spread of the virus by location in the tropical zone; and d) earlier preventive measures to contain the spread of SARS-CoV-2 infection. Therefore, it is possible to establish that the situation in this country will be different from in European Mediterranean and that Colombia could have different endpoints from Spain and Italy.

Intervenciones farmacéuticas y desenlaces clínicos en un programa de gerenciamiento de antimicrobianos / Pharmaceutical interventions and clinical outcomes in an antimicrobial stewardship program

Resumen Introducción: La participación del farmacéutico en el programa de gerenciamiento de antimicrobianos (PGAn) se ha asociado con mejores resultados. Objetivos: Describir las intervenciones farmacéuticas y desenlaces clínicos de un PGAn centrado en antimicrobianos de amplio espectro, en pacientes hospitalizados en una institución de alta complejidad. Método: Estudio observacional, prospectivo, en pacientes ingresados a una clínica de alta complejidad entre agosto de 2016 y septiembre de 2017. En el entorno de un PGAn, un farmacéutico con entrenamiento en enfermedades infecciosas evaluó e intervino la antibioticoterapia, en conjunto con el médico infectólogo, quien realizó la modificación de la antibioticoterapia pertinente. Adicionalmente, se documentó el desenlace clínico. Resultados: Se incluyeron 258 pacientes. El 16,1% de los antimicrobianos se valoró como no indicado. Se realizaron 126 intervenciones farmacéuticas con 82,5% de aceptación. El desenlace principal fue la curación clínica y/o microbiológica de la patología infecciosa. Conclusión: El problema asociado al antimicrobiano con mayor frecuencia en la población de estudio fue el espectro antimicrobiano con respecto a la sensibilidad del microorganismo. Siendo consecuentes, el de-escalamiento fue la intervención farmacéutica con mayor prevalencia. Se alcanzó un porcentaje de aceptación similar a otros estudios, de las intervenciones realizadas por el farmacéutico en el entorno del PGAn. La curación clínica y/o microbiológica fue la principal causa de egreso hospitalario.

Abstract Background: The pharmacist's participation in the antimicrobial stewardship program (AMSP) has been associated with better outcomes. Aims: To describe the pharmaceutical interventions and clinical outcomes of a PGA focused on broad-spectrum antibiotics in hospitalized patients in a tertiary healthcare setting. Method: Prospective observational study in patients admitted to a tertiary healthcare setting between August-2016 and September-2017. In the context of a AMSP, a pharmacist training in infectious diseases evaluated and intervened antibiotic therapy, with the infectious disease specialist, who performed relevant modification of the antibiotic therapy. In addition, the clinical outcome was evaluated and documented. Results: 258 patients were included. 16.1% of antibiotics were assessed as not indicated. A total of 126 pharmaceutical interventions were performed with 82.5% acceptance. The main outcome was the clinical and/or microbiological cure of infection. Conclusion: The problem associated with the antibiotic most frequently in the study population was the antimicrobial spectrum. Being consistent, de-escalation was the pharmaceutical intervention with the highest prevalence. A high percentage of acceptance of the interventions performed by the pharmacist in the environment of the PGAn was considered. Clinical and/or microbiological cure was the main cause of hospital discharge.

Design and development of a mobile app of drug information for people with visual impairment.

BACKGROUND: People with visual impairment presents difficulties to access the labels information of medicines. In this sense, technological tools can contribute to improve access to this information and the appropriate use of medicines in this population. However, currently, in Colombia, there are no tools to facilitate this process. OBJECTIVE: To design and development of a mobile app of drug information for people with visual impairment, which allows them to access information for the appropriate use of medicines. METHODS: A user-centered design process is carried out in four phases was used: a) Identification the needs and barriers for appropriate use of medicines; b) Lifting of requirements, c) Interface design and prototyping, and development of the mobile app, and d) Usability test. RESULTS: The study involved 48 people with visual disability, of which 69% required assistance for the use of medicines. The main barriers identified were access to information and dosing. A total of ten user requirements were identified, based on these and international accessibility standards FarmaceuticApp was designed and developed, incorporating the problems that were identified in the usability test. CONCLUSION: A mobile app of drug information for people with visual impairment using a user-centered design process was designed and developed, highlighting the importance of involving the users and other stakeholders in the design and development m-health technologies. FarmaceuticApp could contribute to the appropriate use of medicines and improve therapeutic adherence, as well as autonomy and independence in people with visual impairment.

[Hypo or hyperglycemia associated with fluoroquinolone use]. / Disglucemia asociada a fluoroquinolonas: una revisión estructurada.

Fluoroquinolone type antimicrobials can cause hypo or hyperglycemia in certain patients. We performed a structured review about this side effect, searching articles published in English or Spanish with full text access in PubMed/Medline. The following MESH terms were used: Hypoglycemia, Hyperglycemia, Quinolones, Ciprofloxacin, Levofloxacin, Moxifloxacin. Additionally, we evaluated the clinical relevance of potential drug interactions, based on the probability of occurrence and the severity of the interaction effect. We obtained 42 publications about the issue; 22 references were selected, where the severity of the interaction in patients with risk factors was evaluated. Patients receiving antidiabetic medications and with risk factors such as advanced age and renal failure may be more likely to have a severe hypoglycemia. In these patients, this drug interaction should be considered clinically relevant since its risk is high or very high.
