Un mecanismo nefrogénico subyace a la poliuria inducida por dexmedetomidina: informe de un caso / Nephrogenic mechanism underlies dexmedetomidine-induced polyuria: A case report

La dexmedetomidina, agonista del adrenorreceptor α, se utiliza cada vez más como agente sedativo-hipnótico y analgésico, aunque su popularidad suscita preocupación acerca de los efectos secundarios de dicho fármaco.La bradicardia y la hipotensión son efectos adversos comunes, pero también existen diversos informes de gasto urinario excesivo, posiblemente debido a la secreción de vasopresina y a la permeabilidad de los conductos colectores.La poliuria se resuelve normalmente con la discontinuación del fármaco, no habiéndose reportado morbilidad significativa. La identificación temprana, la eliminación del agente y el tratamiento son imperativos para minimizar las complicaciones, principalmente natremia y síntomas neurológicos.Este informe de caso describe la poliuria relacionada con dexmedetomidina durante la anestesia general libre de opioides para cirugía mayor de cabeza y cuello. Nuestra hipótesis de etiología nefrogénica se ve reforzada por los datos analíticos obtenidos. También describimos cómo abordar la poliuria intraoperatoria. (AU)

Dexmedetomidine's α-adrenoreceptor agonism has been gaining popularity in the anesthetic room as a sedative-hypnotic and analgesic agent, and with extensive perioperative use rising concern about side effects is necessary.Bradycardia and hypotension are common but excessive urine output is increasingly reported, suggested mechanisms being vasopressin secretion and increasing permeability of the collecting ducts.Polyuria usually resolves with discontinuation of the drug and significant morbidity has not been reported. Early identification, removal of agent and treatment are imperative to minimize complications, mainly associated with natremia levels and neurological symptoms.This case report describes a dexmedetomidine-related polyuric syndrome during opioid-free general anesthesia for major head and neck surgery. A nephrogenic mechanism for the clinical effect is proposed and reinforced by analytical data obtained. An intra-operative polyuria approach is also delineated. (AU)

Un reto biomédico: facilitar la disponibilidad informativa acerca de la relación entre la microbiota intestinal, medicamentos y vacunas / A biomedical challenge: to facilitate the availability of information about the relationship between gut microbiota, drugs and vaccines / Um desafio biomédico: facilitar a disponibilidade de informações sobre a relação entre a microbiota intestinal, medicamentos e vacinas

Resumen El personal biomédico carece de plataformas informatizadas que resuman los principales mecanismos de colaboración entre los microbios intestinales y los seres humanos en cuanto a la absorción y transformación de los medicamentos o vacunas y sus respuestas homeostáticas. Por esta razón, el presente trabajo tiene como objetivo aportar evidencias y recomendaciones para el diseño de una plataforma de consulta biomédica, referente a esta relación, lo cual permitirá la valoración de la posible inclusión de la taxa y abundancia microbiana intestinal en los protocolos de evaluación de la efectividad de los mismos. La encuesta realizada a un grupo de profesionales, destinada a la verificación de las posibilidades de acceso y especificidad de este tipo de información posibilitó la identificación de los tópicos principales para la conexión entre grupos de medicamentos, estructura tridimensional, moduladores y mediadores de la respuesta homeostática, biomarcadores, relación inter-reinos y mecanismos patogénicos, de manera que se fusione toda la información "ómica" humanomicrobiota en una plataforma dentro de la página del NCBI, la cual se propone que se denomine Pharmacolobiomic o Pharmaco-metagenomic. La información existe en las bases de datos contenidas en NCBI-NIH, según la búsqueda realizada y el filtrado a partir de 28 628 referencias. A partir de la presente propuesta se demostró la necesidad de contar con una plataformafarma cometagenómica que resuma el papel de la microbiota intestinal en el metabolismo y la efectividad de los fármacos y vacunas; así como disponer de la actualización sistemática para los profesionales en cuanto a la microbiota como biomarcador, en los protocolos de ensayos clínicos.

Abstract Biomedical staff lacks a computer platform that summarises the main mechanisms of collaboration between intestinal microbes and humans, related to the absorption and transformation of drugs and vaccines and their ho-meostatic responses. For this reason, the aim of this work is to provide some evidences and recommendations for the design of a biomedical consultation platform, about the relationship between the microbiota and the effect of drugs or vaccines. These evidences will support the assessment for inclu¬sion of taxa and gut microbial abundance, as a part of clinical protocols of effectiveness. The survey carried out on a group of biomedical professionals, aimed at verifying the possibilities of access and specificity of this type of information made it possible to identify the main topics for the connection between drug groups, three-dimensional structure, modulators and mediators of the homeostatic response, biomarkers, inter-kingdom relationship and pathogenic mechanismsin such a way that all the human-microbiota "omics" information will be shown into a sub-platform within NCBI-NIH, which could be called Pharmacolobiomic or Pharmaco-metagenomic. The information is present in the databases contained in the NCBI, taking into account this search and filtering, from 28 628 references. Based on this proposal, the need for a pharmacometagenomic platform that summarises the role of the intestinal microbiota in the metabolism and effectiveness of drugs and vaccines was demonstrated, as well as having the systematic update for professionals about the microbiota as a biomarker, in clinical trial protocols.

A nephrogenic mechanism underlies dexmedetomidine-induced polyuria. A case report.

Dexmedetomidine's α-adrenoreceptor agonism has been gaining popularity in the anesthetic room as a sedative-hypnotic and analgesic agent, and with extensive perioperative use rising concern about side effects is necessary. Bradycardia and hypotension are common adverse effects, but there are also several reports of excessive urine output, possibly due to vasopressin secretion and permeability of collecting ducts. Polyuria usually resolves with discontinuation of the drug, and significant morbidity has not been reported. Early identification, removal of the agent, and treatment are imperative to minimize complications - mainly natremia and neurological symptoms. This case report describes a dexmedetomidine-related polyuric syndrome during opioid-free general anesthesia for major head and neck surgery. A nephrogenic mechanism for the clinical effect is proposed and reinforced by analytical data obtained. An intra-operative polyuria approach is also delineated.

Análisis del programa de Farmacología Clínica en el plan de estudio E para la carrera de Medicina / Analysis of the program of Clinical Pharmacology in the E plan study for the Medicine career i: en

Introducción: En Cuba han existido varias concepciones sobre planes de estudio. La necesidad de revisar y proponer cambios que aseguren los niveles de calidad deseados en el proceso de formación integral de los futuros profesionales motivó a investigar los elementos teóricos y metodológicos que regulan y orientan el proceso de enseñanza-aprendizaje en la asignatura Farmacología Clínica. Objetivo: Analizar el programa de Farmacología Clínica del plan de estudio E para la carrera de Medicina desde un enfoque crítico y sistematizado. Métodos: Se realizó un estudio cualitativo del programa de estudio de la asignatura Farmacología Clínica según el plan E, vigente en la Universidad de Ciencias Médicas de Santiago de Cuba, durante el 2022, para lo cual se utilizaron los métodos de revisión documental, los documentos rectores del proceso docente en la educación superior y la metodología propuesta por algunos autores. Resultados: Varios temas enunciaban un número excesivo de objetivos específicos sin tener en cuenta el nivel de asimilación; la forma de organización de la enseñanza más utilizada fue la conferencia. En las evaluaciones frecuentes no se tuvo en cuenta el trabajo investigativo independiente; en tanto, la bibliografía básica correspondió a una edición del 2002. Conclusiones: El programa no requirió trasformaciones temáticas, pero desde el punto de vista didáctico deben modificarse componentes del proceso de enseñanza-aprendizaje y, además, se debe actualizar la bibliografía básica pertinente.

Introduction: In Cuba several conceptions have existed on the study plans. The necessity to revise and propose changes that assure the levels of quality wanted in the process of integral formation of the future professionals motivated to investigate the theoretical and methodological elements that regulate and guide the teaching-learning process in the Clinical Pharmacology subject. Objective: To analyze the program of Clinical Pharmacology of the E plan study for the medicine career, from a critical and systematized approach. Methods: A qualitative study of the study program in the Clinical Pharmacology subject was carried out according to the E plan, effective in the University of Medical Sciences in Santiago de Cuba, during 2022, for which the methods of documental review, the rector documents of the teaching process in higher education and the methodology proposed by some authors were used. Results: Several topics enunciated an excessive number of specific objectives without taking into account the level of assimilation; the form of organization most used in teaching was the conference. Independent investigative work was not taken into account in frequent evaluations; meanwhile, the basic bibliography corresponded to an edition from 2002. Conclusions: The program did not require of thematic transformations, but from the didactic point of view components of the teaching-learning process should be modified, besides updating the pertinent basic literature.

Impacto do uso sistêmico de estatinas e de bisfosfonatos nos tecidos periodontais: revisão narrativa / Impact of the systemic use of statins and bisphosphonates in the periodontal tissues: narrative review

Introdução: A literatura tem apontado uma possível relação entre diversas condições sistêmicas e as doenças periodontais. Dentro das doenças sistêmicas que podem gerar o uso crônico de medicamentos, com potencial associação com as doenças periodontais, destacam-se a hipercolesterolemia e o uso de estatinas; e as doenças do metabolismo ósseo e o uso de bisfosfonatos. Objetivo: Dessa maneira, o presente estudo objetivou revisar a literatura sobre o efeito das estatinas e dos bisfosfonatos nos parâmetros clínicos e radiográficos periodontais de indivíduos adultos. Resultados: Apenas estudos observacionais em humanos foram incluídos. Um estudo mostrou que, em pacientes que apresentam doença periodontal e usam estatina, houve 37% menos bolsas periodontais (profundidade de sondagem ≥4mm) quando comparadas aos que não utilizam a medicação, além de apresentarem menor índice de carga inflamatória e menor perda de inserção clínica. Em relação aos bisfosfonatos em indivíduos com doenças que envolvem o metabolismo ósseo, sugere-se que a utilização do fármaco tem obtido resultados positivos nos parâmetros periodontais, como menores sinais clínicos de inflamação gengival, menor profundidade de sondagem, menor perda de inserção clínica e maior nível de osso alveolar, quando comparados aos que nunca realizam essa terapia. Conclusão: Dessa forma, as estatinas e os bisfosfonatos apresentam efeitos promissores, em pacientes sob tratamento para suas respectivas condições sistêmicas, na melhoria dos parâmetros periodontais, porém é importante salientar que são necessários mais estudos sobre o assunto para melhor entender os reais efeitos a longo prazo do uso desses fármacos.(AU)

Introduction: The literature showed a possible relationship between several systemic conditions and periodontal diseases. Within the systemic diseases that can generate the chronic use of these drugs, potentially related with periodontal diseases, it may be cited the hypercholesterolemia and the use of statins; and bone metabolism diseases and the use of bisphosphonates. Objective: In this sense, the present study aimed to review the literature about the effect of statins and bisphosphonates in the periodontal parameters of adults individuals. Results: Only observational studies in humans were included. A study showed that, in patients with periodontal disease and users of statins, there 37% fewer periodontal pockets (probing depth ≥4mm) when compared to those who do not use the medication, as well as having a lower rate of inflammatory burden and less loss of clinical insertion. Regarding the bisphosphonates in individuals diagnosed with diseases involving bone metabolism, it was suggested that the use of the drug has obtained positive results in periodontal parameters, such as a greater absence of plaque, less clinical signs of gingival inflammation, less probing depth, lower level of clinical insertion and higher level of alveolar bone when compared to those who never undergo this therapy. Conclusion: Thus, statins and bisphosphonates have promising effects in patients under treatment for their respective systemic condition in improving periodontal parameters, but it is important to emphasize that further studies on the subject are needed to better understand the long-term effects of the use of these drugs.(AU)

Interações potenciais entre os medicamentos comumente prescritos em cirurgia oral e os medicamentos em uso pelo paciente: estudo piloto

Introdução: A alta prevalência do uso de medicamentos na população brasileira pode interferir na prescrição odontológica. Objetivos: Identificar os medicamentos em uso por pacientes atendidos em uma clínica de cirurgia oral menor e estimar os riscos de interações medicamentosas (IM) potenciais com fármacos comumente prescritos em procedimentos cirúrgicos. Materiais e Métodos: Realizou-se um estudo piloto analítico e transversal, sendo incluídos 24 pacientes atendidos na Clínica de Cirurgia Oral da Faculdade de Odontologia de uma universidade pública brasileira. Os dados foram coletados por meio de um questionário exploratório. Todos os medicamentos foram classificados no sistema Anatomical Therapeutic Chemical (ATC). As IM potenciais foram analisadas no banco de dados do Drugs® após correlação entre os medicamentos em uso pelo paciente e os medicamentos comumente prescritos em cirurgia oral.Resultados: Observou-se prevalência de 66,7% (n= 16) no uso de pelo menos 1 medicamento dentre os pacientes atendidos na clínica de cirurgia oral, com média de 3,5 (±2,2) medicamentos, sendo a polifarmácia identificada em 16,6% pacientes (n= 4). A média de idade dos usuários de medicamentos foi de 52 (±16) anos e totalizou-se 56 medicamentos. Os fármacos mais prevalentes foram aqueles atuantes nos sistemas nervoso e cardiovascular. Quando simuladas as adições dos fármacos comumente prescritos em cirurgia oral (anti-inflamatórios, analgésicos e antimicrobianos) aos medicamentos em uso pelos 16 pacientes, identificou-se 75 IM potenciais diferentes, sendo 61 (81%) de gravidade moderada e 14 (19%) de gravidade alta. As IM potenciais mais frequentes foram de anti-hipertensivos com anti-inflamatórios, enquanto as de importância clínica grave envolveram fármacos de ação central e analgésicos opioides. Conclusão: Observou-se alta prevalência na utilização de medicamentos pelos pacientes atendidos na clínica de cirurgia oral, com importante risco de interações com medicamentos prescritos em procedimentos cirúrgicos.

Introduction: The high prevalence of drug use in the Brazilian population can interfere with dental prescriptions.Objective: To identify drugs being used by patients seen at a minor oral surgery clinic and to estimate the risks of potential drug interactions (DI) with drugs commonly prescribed in surgical procedures. Materials and Methods: An analytical and cross-sectional pilot study was carried out, including 24 patients treated at the Oral Surgery Clinic of the Dental School of a Brazilian Federal University. Data were collected through an exploratory questionnaire. All drugs were classified in the Anatomical Therapeutic Chemical (ATC) system. Potential DI were analyzed in the Drugs® database after correlation between the drugs used by the patient and the drugs commonly prescribed in oral surgery.Results: There was a prevalence of 66.7% (n= 16) in the use of at least 1 medication among patients seen at the oral surgery clinic, with a mean of 3.5 (±2.2) medications, with polypharmacy identified in 16.6% patients (n= 4). Mean age of medication users was 52 (±16) years, totaling 56 medications. The most prevalent drugs were those acting on the nervous and cardiovascular systems. When the additions of drugs commonly prescribed in oral surgery (anti-inflammatory drugs, analgesics and antimicrobials) to the drugs used by the 16 patients were simulated, 75 different potential DI were identified, 61 (81%) of moderate severity and 14 (19%) of high gravity. The most frequent potential DIs were antihypertensives with anti-inflammatory drugs, while those of serious clinical importance involved centrally acting drugs and opioid analgesics. Conclusion: There was a high prevalence of medication use by patients seen at the oral surgery clinic, with a significant risk of interactions with prescribed medications in surgical procedures.

Bases científicas del principio de curación homeopática en la farmacología moderna / Scientific bases of the homeopathic healing principle in modern pharmacology

La homeopatía emplea el denominado 'principio de similares' como método terapéutico ­ el cual consiste en administrar medicamentos que provocan ciertos síntomas en individuos sanos para tratar síntomas similares en individuos enfermos (similia similibus curantur) - para inducir una reacción curativa secundaria del cuerpo en contra de sus propios trastornos. Esta reacción secundaria (vital, homeostática o paradójica) del cuerpo se basa en el 'efecto de rebote' de los fármacos modernos, un tipo de evento adverso que se produce después de interrumpir varias clases de fármacos prescritos según el 'principio de los contrarios' (contraria contrariis curantur). Objetivo: La presente revisión ha buscado justificar científicamente el principio de curación homeopática frente a la farmacología clínica y experimental a través de un estudio sistemático del efecto de rebote de los fármacos modernos o reacción paradójica del cuerpo. Métodos: Empleando como referencia estudios y revisiones sobre el tema publicados a partir de 1998, actualizamos los datos añadiendo estudios recientes incluidos en la base de datos PubMed. Resultados: El efecto de rebote se produce después de interrumpir varias clases de fármacos con acción contraria a los síntomas de las enfermedades, exacerbándolos a niveles superiores a aquellos previos al tratamiento. Independientemente de la enfermedad, fármaco, dosis y duración del tratamiento, el fenómeno del rebote se manifiesta en una pequeña proporción de los individuos susceptibles. Siguiendo las premisas homeopáticas, los fármacos modernos también podrían usarse según el principio de la similitud terapéutica, empleando entonces el efecto de rebote (reacción paradójica) con propósito curativo. Conclusiones: Evidenciado por cientos de estudios que constatan la similitud de conceptos y manifestaciones, el efecto de rebote de los fármacos modernos justifica científicamente el principio de la cura homeopática. Aunque el fenómeno de rebote es un evento adverso estudiado por la farmacología moderna, no es conocido por los profesionales de la atención médica, lo cual priva a los médicos de un conocimiento indispensable para el manejo seguro de los fármacos.

Homeopathy employs the so-called 'principle of similars' as therapeutic method - which consists in administering medicines that cause certain symptoms in healthy individuals to treat similar symptoms in sick individuals (similia similibus curantur) - to induce a secondary and healing reaction by the body against its own disorders. This secondary (vital, homeostatic or paradoxical) reaction of the body is based on the 'rebound effect' of modern drugs, a type of adverse event that occurs following discontinuation of several classes of drugs prescribed according to the 'principle of contraries' (contraria contrariis curantur). Aim: The present review sought to scientifically substantiate the homeopathic healing principle vis-à-vis experimental and clinical pharmacology through a systematic study of the rebound effect of modern drugs or paradoxical reaction of the body. Methods: Employing as reference studies and revisions on the subject published since 1998, we updated the data adding recent studies included in database PubMed. Results: The rebound effect occurs after discontinuation of several classes of drugs with action contrary to the symptoms of diseases, exacerbating them to levels above the ones before treatment. Regardless of disease, drug, dose and duration of treatment, the rebound phenomenon manifests in a small proportion of susceptible individuals. Following the homeopathic premises, modern drugs might also be used according to the principle of therapeutic similitude, thus employing the rebound effect (paradoxical reaction) with curative intent. Conclusions: Evidenced by hundreds of studies that attest to the similarity of concepts and manifestations, the rebound effect of modern drugs scientifically substantiates the principle of homeopathic cure. Although the rebound phenomenon is an adverse event studied by modern pharmacology, it is not known by health care professionals, thus depriving doctors of knowledge indispensable for safe management of drugs.

Efficacy and marginal cost of treatment with tocilizumab in COVID-19 patients. / Resultados en la práctica asistencial y coste marginal del tratamiento con tocilizumab en pacientes COVID-19.

OBJECTIVE: To describe the marginal cost and survival of patients treated with tocilizumab in a university hospital under real-life conditions and to evaluate factors that could influence costs and health outcomes will be evaluated. METHODS: Observational, single-center, retrospective study of a cohort of adult patients infected with SARS-CoV-2 treated with tocilizumab. The one-year restricted mean survival time was analyzed in life-years gained (LYG). The influence of sex, age and severity on patient survival was evaluated. The marginal cost/LYG and marginal cost/survivor ratios were calculated. RESULTS: 508 patients (66 ± 13 years; 32% women) were included. Seventeen percent were admitted to the ICU. Overall survival was 77%. Age older than 71.5 years (HR = 1.08; 95% CI 1.07-1.10; p < 0.001) and ICU admission at initiation of treatment (HR = 2.01; 95% CI 1.30-3.09; p = 0.002) were identified as risk factors. The total budgetary impact of tocilizumab in the period analyzed was 206,466 euros. The patients with the highest cost per unit of health outcome were those admitted to the ICU and those over 71.5 years, with a marginal cost/LYG of € 966 and a marginal cost/survivor of € 1,136. CONCLUSION: The efficiency of treatment with tocilizumab is associated with the age and severity of the patients. The figures are lower in all subgroups than the thresholds usually used in cost-effectiveness evaluations. The results of the present study suggest that early first dose of tocilizumab is an efficient strategy.

Glicopeptídeos: aspectos farmacológicos e aplicações clínicas / Glycopeptides: pharmacological aspects and clinical applications / Glicopeptidos: aspectos farmacológicos y aplicaciones clínicas

O uso indiscriminado dos antimicrobianos tem gerado um problema significativo na saúde pública, acarretando impactos negativos como fracasso na farmacoterapia frente as infecções bacterianas e aumentos nos custos assistenciais. Esta revisão narrativa tem como objetivo descrever as propriedades farmacocinéticas e farmacodinâmicas e aplicações clínicas dos principais antibióticos pertencentes a classe dos glicopeptídeos. A busca de artigos foi realizada nas seguintes bases de dados: Literatura Latino Americana e do Caribe em Ciências da Saúde (LILACS/PUBMED), SciELO (Scientific Electronic Library Online) e Biblioteca Virtual em Saúde (BVS). A vancomicina e a teicoplanina são fármacos de primeira linha no tratamento de infecções por bactérias gram-positivas com resistência a outros antibióticos. Ambos apresentam estruturas cíclicas complexas, contendo aminoácidos ligados a grupos de carboidratos que lhe conferem propriedades únicas. A administração dos glicopetídeos deve ponderar fatores relacionados ao paciente como faixa etária, função renal, desnutrição e obesidade devido a sua heterogeneidade farmacocinética, por isso o monitoramento sérico é recomendado para assegurar concentrações plasmáticas efetivas. Diante do exposto, o uso adequado e baseado em evidência científica dessa importante classe de antibióticos visa otimizar o tratamento farmacoterapêutico e diminuir o avanço da resistência bacteriana.

The indiscriminate use of antimicrobials has generated a significant problem in public health, causing negative impacts such as failure in pharmacotherapy against bacterial infections and increases in healthcare costs. This narrative review aims to describe the pharmacokinetic and pharmacodynamic properties and clinical applications of the main antibiotics belonging to the class of glycopeptides. The search for articles was carried out in the following databases: Latin American and Caribbean Literature in Health Sciences (LILACS/PUBMED), SciELO (Scientific Electronic Library Online), and Virtual Health Library (BVS). Vancomycin and teicoplanin are first- line drugs in infections caused by gram-positive bacteria it resistant to other antibiotics. Both have complex cyclic structures containing amino acids linked to carbohydrate groups that give them unique properties. The administration of glycopeptides must consider patient-related factors such as age group, renal function, malnutrition, and obesity due to its pharmacokinetic heterogeneity. Therefore, serum monitoring is recommended to ensure effective plasma concentrations. Thus, the proper use based on scientific evidence of this important class of antibiotics aims to optimize pharmacotherapeutic treatment and reduce the progress of bacterial resistance.
