Uso de antipsicóticos en los pacientes con demencia en España: comparación con la prescripción de los inhibidores de la acetilcolinesterasa y de la memantina, y análisis de las asociaciones / Use of antipsychotics in patients with dementia in Spain: Comparison with prescription of acetylcholinesterase inhibitors and memantine and analysis of associations

Objetivo: Se ha analizado la prevalencia de antipsicóticos, inhibidores de la acetilcolinesterasa (IACE) y memantina en pacientes con demencia en España y la influencia de estas asociaciones en su prescripción. Método: Estudio descriptivo, retrospectivo y transversal de la base BIFAP de 2017 en los mayores de 65 años con demencia. Se recogieron las prescripciones de antipsicóticos, los IACE y la memantina. Para los antipsicóticos también se recogieron, la duración del tratamiento y el tiempo desde el diagnóstico de demencia, al de prescripción. Resultados: Se recuperaron 1.327.792 sujetos, 89.464 (6,73%) con demencia. El 31,76% tuvieron prescritos antipsicóticos; los más frecuentes: quetiapina (58,47%), risperidona (21%) y haloperidol (19,34%). Las prescripciones de IACE y memantina fueron más frecuentes en los menores de 84 años y las de antipsicóticos en los mayores de 85 años (p<0,001). Los antipsicóticos se mantuvieron una media de 1.174,5 días. En el 26,4% de los casos se prescribieron aislados, OR: 0,61 (IC 95%: 0,59-0,62), en el 35,85% asociados a IACE, OR: 1,26 (IC 95%: 1,22-1,30) y en el 42,4% a memantina, OR: 1,69 (IC 95%: 1,62-1,78); p<0,000). Desde el diagnóstico de demencia transcurrieron de 461 días (±1.576,5) cuando se prescribieron aislados; 651 días (±1.574,25) asociados a IACE y 1.224 (±1.779) a memantina. Conclusiones: Una tercera parte de los pacientes con demencia tuvieron prescritos antipsicóticos, mayoritariamente atípicos, más frecuentemente en los mayores de 85 años y durante periodos prolongados. La prescripción de IACE y memantina se asoció al incremento del riesgo de uso de antipsicóticos, pero paradójicamente, a la prolongación del tiempo hasta su prescripción.(AU)

ObjectiveWe have analyzed the prevalence of antipsychotics in patients with dementia in Spain, their age distribution and the influence of treatment with IACEs and memantine on their prescription. Method: Descriptive, retrospective and cross-sectional study of the 2017 BIFAP database in over 65 years of age with dementia. Prescriptions of antipsychotics, IACEs and memantine were collected. For antipsychotics were also collected, the duration of treatment and time from dementia diagnosis to prescription. Results: A total of 1,327,792 subjects were retrieved, 89,464 (6.73%) with dementia. Antipsychotics were prescribed in 31.76%; by frequency: quetiapine (58.47%), risperidone (21%) and haloperidol (19.34%). Prescriptions of IACEs and memantine were clustered in those younger than 84 years and antipsychotics in those older than 85 (P<.001). Antipsychotics were maintained for a mean of 1174.5 days. In 26.4% of cases they were prescribed alone, OR 0.61 (95% CI: 0.59-0.62), in 35.85% associated with IACEs, OR 1.26 (95% CI: 1.22-1.30) and in 42.4% with memantine, OR 1.69 (95% CI: 1.62-1.78) (P<.000). From the diagnosis of dementia, 461 days (±1576.5) elapsed when isolated drugs were prescribed; 651 days (±1574.25) associated with IACEs and 1224 (±1779) with memantine. Conclusions: One third of patients with dementia were prescribed antipsychotics, mostly atypical, more frequently in those older than 85 years and for prolonged periods. IACEs and memantine were associated with the risk of antipsychotic prescription, but paradoxically, with prolonged time to onset.(AU)

Fármacos antipsicóticos de segunda generación y su impacto en el tejido adiposo / Second-generation antipsychotic drugs and their impact on adipose tissue

La esquizofrenia es un trastorno neuropsiquiátrico crónico que afecta a 21 millones de personas en todo el mundo. Actualmente, los fármacos antipsicóticos de segunda generación o atípicos (FASG) son los medicamentos de elección para el tratamiento de esta enfermedad. Sin embargo, a pesar de su alta eficacia en contrarrestar la sintomatología neuropsiquiátrica de la esquizofrenia, observaciones clínicas recientes en pacientes tratados con FASG evidencian un aumento en la prevalencia de diferentes alteraciones metabólicas, entre las que se incluyen el aumento de peso corporal, la hiperglucemia y la dislipidemia. A pesar de que no se conocen en detalle los mecanismos moleculares responsables de estos efectos secundarios, cada vez más investigaciones apuntan a una relación entre los tratamientos con FASG y las alteraciones en los diferentes depósitos de tejido adiposo blanco, marrón y beige. En esta revisión analizamos el conocimiento actual en esta área destacando aspectos moleculares de la biología de los adipocitos, entre los que se encuentran los procesos de diferenciación, metabolismo lipídico, función termogénica y el proceso de pardeamiento o beiging.(AU)

Schizophrenia is a chronic neuropsychiatric disorder that affects 21 million people worldwide. Currently, second-generation or atypical antipsychotics (SGAs) are the first-line medications for the treatment of this disease. However, despite its high efficacy in counteracting the neuropsychiatric symptoms of schizophrenia, recent clinical investigations in patients treated with SGAs show an increase in the prevalence of pivotal metabolic alterations, including increased body weight, hyperglycemia and dyslipidemia. Although the molecular mechanisms responsible for these side effects are not fully understood, cumulative evidences associate SGA administration with alterations in the different adipose tissue depots of white, brown and beige adipocytes. In this review, we have recapitulated the current knowledge in this area with a particular focus on the molecular aspects of the adipocyte biology, including differentiation, lipid metabolism, thermogenic function and browning processes.(AU)

Síndrome neuroléptico maligno

El síndrome neuroléptico maligno (SNM) es una reacción adversa medicamentosa potencialmente fatal asociada comúnmente a medicamentos antipsicóticos. Este artículo presenta una revisión actualizada sobre el SNM, aborda su epidemiología, factores de riesgo, presentación clínica, posibles mecanismos subyacentes y tratamiento. Se busca mejorar el reconocimiento temprano, diagnóstico y manejo del SNM en el ámbito clínico para reducir su morbimortalidad. La búsqueda de literatura se realizó en PubMed, fueron priorizados ensayos aleatorizados, revisiones sistemáticas, estudios retrospectivos y reportes de caso. La incidencia del SNM ha disminuido en los últimos años, posiblemente debido a una mejor prescripción y titulación de la medicación. Los factores de riesgo incluyen el uso de antipsicóticos de alta potencia, dosis elevadas, incremento rápido de la dosis y uso de antipsicóticos inyectables de depósito. Se han identificado factores ambientales como la deshidratación, sujeción mecánica y temperaturas extremas. Algunas características psicopatológicas, como la agitación psicomotriz y la confusión, también se han asociado al SNM. Los factores hereditarios y los polimorfismos genéticos pueden influir en la susceptibilidad al SNM, pero se requieren estudios adicionales. La fisiopatología del SNM se relaciona con el bloqueo excesivo de los receptores dopaminérgicos, pero otros cofactores y sistemas neurotransmisores también podrían estar involucrados. El cuadro clínico del SNM se caracteriza por cambios en el estado mental, rigidez muscular, hipertermia, síntomas catatónicos y sudoración profusa. Existen diversas formas de tratamiento, desde medidas generales hasta intervenciones farmacológicas.

The Neuroleptic malignant syndrome (NMS) is a potentially fatal adverse drug reaction commonly associated with antipsychotic medications. This article presents an updated review of NMS, addressing its epidemiology, risk factors, clinical presentation, possible underlying mechanisms, and treatment. The aim is to improve early recognition, diagnosis, and management of NMS in the Peruvian clinical setting to reduce morbidity and mortality. The literature search was conducted in PubMed, prioritizing randomized studies, systematic reviews, retrospective studies, and case reports. The incidence of NMS has decreased in recent years, possibly due to better medication prescription and titration. Risk factors include the use of high-potency antipsychotics, high doses, rapid dose escalation, and the use of depot injectable antipsychotics. Environmental factors such as dehydration, mechanical restraint, and extreme temperatures have been identified. Some psychopathological characteristics, such as psychomotor agitation and confusion, have also been associated with NMS. Genetic factors and genetic polymorphisms may influence susceptibility to NMS, but further studies are needed. The pathophysiology of NMS is related to excessive blockade of dopaminergic receptors, but other cofactors and neurotransmitter systems may be involved. The clinical presentation of NMS is characterized by changes in mental status, muscle rigidity, hyperthermia, catatonic symptoms, and profuse sweating. There are various treatment approaches ranging from general measures to pharmacological interventions.

Hepatoxicity induced by clozapine: Case report and brief review.

INTRODUCTION: Antipsychotics are drugs that can produce transient elevations of hepatic enzymes. Clozapine is an atypical antipsychotic used in treatment-resistant schizophrenia and there is evidence that it can produce elevations of hepatic transaminases, expression of liver damage in a hepatocellular pattern. METHODS: Case report and non-systematic review of the relevant literature. CASE PRESENTATION: A 39-year-old woman with a diagnosis of paranoid schizophrenia attended the emergency department of a general hospital for nausea, vomiting and jaundice that appeared after the initiation of clozapine. There was no clinical improvement during hospitalisation, and death occurred after 44 days. LITERATURE REVIEW: Clozapine can increase the liver enzyme levels transiently and asymptomatically; however, there are clinical criteria that recommend the withdrawal of the antipsychotic. CONCLUSIONS: This is the third case reported in the literature of a fatal outcome of clozapine-induced hepatotoxicity.

Hepatotoxicidad inducida por clozapina: reporte de caso y revisión breve de la literatura

Introducción: Los antipsicóticos son medicamentos que pueden producir elevaciones transitorias de las enzimas hepáticas. La clozapina es un antipsicótico atípico usado en el tratamiento de la esquizofrenia refractaria a los antipsicóticos convencionales y existe evidencia que puede producir elevaciones de las transaminasas hepáticas, expresión de dafño hepático con patrón hepatocelular. Métodos: Reporte de caso y revisión no sistemática de la literatura relevante. Presentación del caso: Una mujer de 39 años con diagnóstico de esquizofrenia paranoide acudió a un servicio de urgencias de un hospital general por náuseas, vómitos e ictericia que apareció tras el inicio de clozapina. No hubo mejoría clínica de la paciente durante la hospitalización, que falleció a los 44 días de su ingreso. Revisión de la literatura: La clozapina puede elevar las cifras de función hepática de manera transitoria y asintomática. Hay criterios clínicos para recomendar la suspensión de este antipsicótico. Conclusiones: Este caso es el tercero en la literatura que registra un desenlace fatal tras un cuadro de hepatotoxicidad inducido por clozapina. © 2021 Asociación Colombiana de Psiquiatría.

Uso de psicofármacos en personas con discapacidad intelectual en Extremadura, España / Use of Psychotropic Drugs in People with Intellectual Disability in Extremadura, Spain

Resumen El uso de psicofármacos es frecuente en adultos con discapacidad intelectual, a menudo por conductas desafiantes en ausencia de diagnóstico de trastorno mental. Investigaciones previas cuestionan la eficacia de estos tratamientos a falta de una enfermedad psiquiátrica, y destacan sus efectos secundarios. El objetivo de esta investigación es analizar el uso de psicofármacos en función del diagnóstico de enfermedad mental y conducta desafiante, así como la distribución de la población según el uso de psicofármacos en 569 adultos con discapacidad intelectual que presentan enfermedad mental o conductas desafiantes. Los datos acerca de la elevada prescripción de psicofármacos y, especialmente, de antipsicóticos alertan sobre la necesidad de una profunda revisión de la práctica clínica que permita reducir el uso de esta medicación en el tratamiento de la conducta y los trastornos mentales en esta población, para garantizar una atención de calidad y el respeto de los derechos de estas personas.

Abstract The use of psychotropic drugs in adults with an intellectual disability is frequent, often for defiant conduct due to the lack of a diagnosis of a mental disorder. Previous research has questioned the efficacy of such treatments in the absence of a psychiatric illness, and the stress has been on the side effects. The objective of this research is to analyze the use of psychotropic drugs based on the diagnosis of mental illness and behavioral disorders, as well as the distribution of the sample according to the use of psychotropic drugs in 569 adults with an intellectual disability who also suffer a mental illness and/or defiant conduct. Our data about the high prescription of psychotropic drugs and especially antipsychotics, warns of the need for a profound review of the clinical practice that would allow a reduction in the use of psychotropic drugs in the treatment of mental disorders and behaviour in the said collective, so as to guarantee quality mental health care for these persons and respect for their rights.

Neuroleptic malignant syndrome associated with atypical antipsychotics: A case report.

INTRODUCTION: Neuroleptic malignant syndrome (NMS) is uncommon, with an incidence of 0.01%-3.23%, and is associated with the use of drugs that intervene with dopamine, causing hyperthermia, muscular rigidity, confusion, autonomic instability and death. CASE REPORT: A 35-year-old man with a history of catatonia, refractory epilepsy and functional impairment, required frequent changes in his anticonvulsant and antipsychotic treatment, due to adverse effects. During 2019, in the month of July, clozapine was changed to amisulpride, in September he developed fever, muscle stiffness, stupor, diaphoresis and tachypnea over a two-week period; paraclinical tests showed elevated creatine phosphokinase (CPK) and leukocytosis, so NMS was considered. The antipsychotic was withdrawn and he was treated with bromocriptine and biperiden, with a good response. Ten days after discharge, he began treatment with olanzapine, which generated a similar episode to the one described in December, with subsequent management and resolution. DISCUSSION: The diagnosis is based on the use of drugs that alter dopamine levels, plus altered state of consciousness, fever, autonomic instability and paraclinical tests showing leukocytosis and elevated CPK. Differential diagnoses must be ruled out. Early diagnosis generally leads to total remission, although some patients will suffer complications, long-term sequelae or recurrences. The recurrence in this case derived from the early reintroduction of the neuroleptic after the first episode. Treatment should be individualised according to severity to avoid mortality. CONCLUSIONS: Atypical antipsychotics are rarely suspected of generating NMS. Moreover, the time to reintroduction after an episode must also be taken into account.

Olanzapina, 26 años: situación actual, conocimientos, actitudes y prácticas de uso entre los psiquiatras españoles / Olanzapina, 26 years old: Current situation, knowledge, attitudes and practices of use among Spanish psychiatrists

Olanzapina es un antipsicótico atípico comercializado en Europa desde finales de 1996, que continúa siendo uno de los principios activos más ampliamente utilizados en la actualidad en el territorio español. Sin embargo, su elevada tasa de eventos adversos metabólicos y su uso en algunos escenarios clínicos continúan siendo motivo de controversia. El objetivo de este estudio fue explorar los conocimientos, actitudes y prácticas del uso de este medicamento entre psiquiatras españoles. Se diseñó y distribuyó un cuestionario autodiligenciado en el que se exploraron algunos aspectos posológicos en la práctica clínica, la experiencia y las tendencias de uso en distintos contextos y expectativas a futuro. Se tabularon los datos y se realizó un análisis descriptivo. Se obtuvieron respuestas de 129 psiquiatras en ejercicio de todo el territorio español, con una edad promedio de 45,46 años (SD=9,57) y una razón mujer:hombre de 1,04:1. Tras más de 25 años en el mercado, olanzapina continúa siendo un antipsicótico ampliamente usado en distintos escenarios clínicos en la esquizofrenia y otros trastornos mentales (preferiblemente a dosis entre 5 y 10 mg/día). Los psiquiatras españoles están familiarizados con la necesidad de establecer estrategias farmacológicas y no farmacológicas para el control metabólico de quienes usan este medicamento.(AU)

Olanzapine, a second-generation antipsychotic marketed in Europe since late 1996, continues to be one of the most widely used molecules in Spain today. However, its high rate of adverse metabolic events and its use in some clinical settings are still controversial. The objective of this study was to explore the knowledge, attitudes, and practices of use of this medication among Spanish psychiatrists. A self-filled questionnaire was designed and distributed. Dosage, experience, and trends of use in different contexts were explored, as well as future expectations. Data were tabulated and a descriptive analysis was performed. 129 practicing psychiatrists throughout the Spanish territory participated in the study, with an average age of 45.46 years (SD=9.57) and a female: male ratio of 1.04:1. After more than 25 years on the market, Olanzapine continues to be an antipsychotic widely used in different clinical settings, both in Schizophrenia and other mental disorders (preferably at doses between 5 and 10 mg/day). Spanish psychiatrists are familiar with the need to establish pharmacological and non-pharmacological strategies for the metabolic control of patients using this drug.(AU)

Síndrome neuroléptico maligno asociado a antipsicóticos atípicos: a propósito de un caso

Introducción: El síndrome neuroléptico maligno (SNM) es infrecuente, con una incidencia del 0,01 al 3,23%, y tiene relación con el consumo de fármacos que interfieren con la dopamina; genera hipertermia, rigidez muscular, confusión, inestabilidad autonómica y la muerte. Caso clínico: Un varón de 35 arios, con antecedentes de catatonía, epilepsia refractaria y deterioro funcional, en tratamiento anticonvulsivo y antipsicótico, requirió cambio frecuente por efectos adversos de este. En julio de 2019 se cambió la clozapina por amisulprida; en septiembre se inicia un cuadro de 2 semanas de fiebre, rigidez muscular, estupor, diaforesis y taquipnea; los paraclínicos mostraron aumento de la creatininasa (CK) y leucocitosis, por lo que se consideró SNM. Se retiró el antipsicótico y se trató con bromocriptina y biperideno, que obtuvieron buena respuesta. A los 10 días del egreso, se inició tratamiento con olanzapina, que generó en diciembre un cuadro clínico similar al descrito, con posterior tratamiento y resolución. Discusión: El diagnóstico se basa en la toma de fármacos que alteren la dopamina, más alteración del estado de conciencia, fiebre e inestabilidad autonómica, junto con paraclínicos como leucocitosis y elevación de la CK. Se debe descartar diagnósticos diferenciales. El diagnóstico temprano generalmente lleva a la remisión total; algunos tendrán complicaciones, secuelas a largo plazo o recidivas. La recurrencia en este caso derivó de la reintroducción temprana del neuroléptico después del primer episodio. El tratamiento se debe individualizar según la gravedad para evitar la muerte. Conclusiones: Rara vez se sospecha que los antipsicóticos atípicos generen SNM; a su vez se debe tener en cuenta el tiempo a la reintroducción después de un episodio.

Revisão clínica: introdução de antipsicóticos na atenção primária à saúde / Clinical review: introduction of antipsychotics into primary health care / Revisión clínica: introducción de antipsicóticos en la atención primaria de salud

Os antipsicóticos são a primeira linha de tratamento para os sintomas psicóticos e suas síndromes. A psicose pode se apresentar como: delírios, alucinações, desorganização do pensamento e alteração do comportamento. Estima-se que 13 a 23% da população os apresente em algum momento ao longo da vida. Esta revisão clínica pretende auxiliar na tomada de decisão sobre quando e como introduzir antipsicóticos na atenção primária à saúde, levando em conta sua eficácia, o perfil de efeitos colaterais e os principais cuidados com as comorbidades relevantes. Realizou-se revisão da literatura nas bases de dados eletrônicos United States National Library of Medicine (PubMed), BMJ Best Practice e UpToDate ­ sumarizadores de evidência ­ no período de outubro a novembro de 2020. Foram incluídos artigos que abordassem a introdução de antipsicóticos na atenção primária, em maiores de 18 anos, com publicação após 2010, em português, inglês, espanhol ou francês. Foram obtidos 76 artigos considerados elegíveis. Destes, 27 foram selecionados para leitura integral. O antipsicótico deve ser recomendado para qualquer pessoa que apresente um primeiro episódio de psicose. Preferencialmente, a escolha terapêutica deve fazer parte do plano conjunto, centrado na pessoa, levando em conta os efeitos colaterais. Não há superioridade na eficácia entre um antipsicótico ou outro, nem mesmo entre grupos. Analisou-se o perfil de eficácia, efeitos adversos, segurança e tolerabilidade dos principais fármacos disponíveis, facilitando a tomada de decisão perante a introdução dos antipsicóticos. Pela escassa literatura nacional, não foi possível analisar o perfil específico para a população brasileira.

Antipsychotics are the first line of treatment for psychotic symptoms and syndromes. Psychosis can present itself as: delusions, hallucinations, disorganized thinking, and altered behavior. It is estimated that 13 to 23% of the population will experience these symptoms at some point in their lifetime. This clinical review aims to assist in the decision-making about when and how to introduce antipsychotics into primary health care, considering their effectiveness, side effect profile, and the main care practices for relevant comorbidities. A literature review was carried out in the electronic databases PubMed, BMJ Best Practice, and UpToDate ­ electronic databases summarizing evidence ­ from October to November 2020. Articles that addressed the introduction of antipsychotics into primary health care, in patients over 18 years of age, published after 2010, in Portuguese, English, Spanish or French, were included. A total of 76 articles were considered eligible. Of these, 27 were selected for full reading. The antipsychotic should be recommended for anyone who experiences a first episode of psychosis. Preferably, the therapeutic choice should be part of a person-centered shared decision-making, considering the side effects. There is no superiority in effectiveness between one antipsychotic or another, not even between groups. The profile of efficacy, adverse effects, safety, and tolerability of the main drugs available were analyzed, facilitating decision-making regarding the introduction of antipsychotics. Due to the scarce national literature, it was not possible to analyze the specific profile for the Brazilian population.

Prevalência de hipertensão arterial em um Centro de Atenção Psicossocial (CPS) em Salvador/Bahia / Prevalence of hypertension in a Psychosocial Care Center in Salvador/Bahia

Fundamento: Pessoas com transtornos mentais têm menor probabilidade de terem sua DCV e sua hipertensão diagnosticadas e possuem taxas de mortalidade duas ou três vezes maiores que a população em geral. Objetivos: estimar a prevalência de hipertensão através da autorreferência, do uso de medicamentos anti-hipertensivos e de valores de pressão arterial maiores ou iguais a 140 e 90 mmHg em população atendida em um Centro de Atenção Psicossocial na cidade de Salvador. Métodos: estudo transversal e exploratório realizado de agosto de 2019 a fevereiro de 2020, por meio da aplicação de questionário com informações sociodemográficas, avaliação clínica e anamnese. Resultados: foram avaliados 284 pacientes, 45,4% deles homens e a média de idade foi de 44,3 + 11,9 anos. A prevalência de hipertensão autorreferida e o uso de medicamentos anti-hipertensivos foram de 67 (23,6%) e 58 (20,4%), respectivamente. A frequência de valores pressóricos sistólico e diastólico acima de 140 x 90 mmHg foi de 47,8%. As frequências de obesidade e sobrepeso foram 40,8% e 31,6%, respectivamente. Foi encontrada prevalência de uso de pelo menos um antipsicótico de 254 (89,4%) e de polifarmácia de 103 (36,3%) pacientes. Conclusões: a prevalência de hipertensão arterial e o uso de medicamentos anti-hipertensivos em nossa população foi semelhante à população em geral. Também foram identificados fatores que podem aumentar o risco de desenvolver DCV, como a alta taxa de uso de medicamentos antipsicóticos e as prevalências de polifarmácia, obesidade e sobrepeso (AU).

Background: People with mental disorders are less likely to have their CVD and hypertension diagnosed and have mortality rates two or three times higher than the general population. Objectives: to estimate the prevalence of hypertension through self- referral, the use of antihypertensive drugs and blood pressure values greater than or equal to 140 and 90 mmHg in a population attended at a Psychosocial Care Center in the city of Salvador. Methods: cross-sectional and exploratory study conducted from August 2019 to February 2020, through the application of a questionnaire with sociodemographic information, clinical evaluation and anamnesis. Results: 284 patients were evaluated, 45.4% of them men and the mean age was 44.3 + 11.9 years. The prevalence of self-reported hypertension and the use of antihypertensive drugs were 67 (23.6%) and 58 (20.4%), respectively. The frequency of systolic and diastolic blood pressure values above 140 x 90 mmHg was 47.8%. The frequencies of obesity and overweight were 40.8% and 31.6%, respectively. A prevalence of use of at least one antipsychotic was found in 254 (89.4%) and polypharmacy of 103 (36.3%) patients. Conclusions: the prevalence of hypertension and the use of antihypertensive drugs in our population was similar to the general population. Factors that may increase the risk of developing CVD have also been identified, such as the high rate of use of antipsychotic drugs and the prevalence of polypharmacy, obesity and overweight (AU).

Sospecha fallida de síndrome neuroléptico maligno en una paciente con esquizofrenia / Failed suspicion of neuroleptic malignant syndrome in a patient with schizophrenia

Introducción: el estado mental alterado es un término general que se utiliza para describir varios trastornos del funcionamiento mental, que pueden variar desde una ligera confusión hasta el coma. En general no es un diagnóstico, por el contrario hace referencia a un grupo de síntomas neurológicos variables e inespecíficos que requieren una mayor determinación de las causas. Dentro de estas se deben considerar en el adulto mayor los efectos adversos e interacciones medicamentosas. Los pacientes con antecedente de esquizofrenia requieren tratamiento de por vida aunque los síntomas desaparezcan, por ello los medicamentos antipsicóticos deben tenerse en cuenta por sus potenciales efectos asociados. El síndrome neuroléptico maligno (SNM) es uno de estos efectos adversos con riesgo de mortalidad. Presentación del caso: se presenta el caso de una paciente de 78 años que ingresó al servicio de urgencias de un hospital de tercer nivel por alteración del estado de conciencia, con antecedentes de esquizofrenia y múltiples comorbilidades, que representan un reto en el abordaje inicial en el servicio de urgencias; los paraclínicos tomados mostraron elevación de la CPK

Introduction: Altered mental status (AMS) is a general term used to describe various disorders that affect mental function. AMS ranges from mild confusion to coma. Normally, it is not a diagnosis, instead it refers to a group of variable and nonspecific neurological symptoms which require further determination of the causes. Drugs adverse effects and interactions must be taken into account in the elderly. Schizophrenia patients require lifelong treatment even if their symptoms disappear, therefore antipsychotic drugs should be considered due to their potential side effects. Neuroleptic malignant syndrome (NMS) is one of these life-threatening adverse reactions. Case presentation: a case is presented in a 78-year-old female patient, with a history of schizophrenia and multiple comorbidities, admitted to a tertiary hospital emergency room for altered consciousness which posed a challenge for the emergency initial approach; laboratory workup revealed elevated CPK levels.

Uso ambulatorio de medicamentos potencialmente inapropiados en adultos mayores usuarios de la RAP Metropolitana de ASSE durante 2019 / Potentially inappropriate medication use in older adults assisted as outpatients in ASSE's Metropolitan RAP (Primary Health Care) during 2019 / Uso ambulatorial de medicamentos potencialmente inapropriados em idosos usuários da RAPE Metropolitana da ASSE durante 2019

Introducción: los adultos mayores son una población de riesgo para el desarrollo de reacciones adversas a los medicamentos. Los medicamentos potencialmente inapropiados son aquellos que representan mayores riesgos que beneficios en este grupo etario. Se cuenta con herramientas de apoyo a la prescripción en geriatría que permiten identificar a estos medicamentos y mediante la aplicación de estudios de utilización de medicamentos, podemos describir o analizar el uso de los mismos en una población. Objetivos: reconocer disponibilidad de medicamentos potencialmente inapropiados para adultos mayores en la RAP metropolitana de ASSE durante 2019 y establecer un diagnóstico de situación de consumo de los mismos durante ese año. Método: se realizó un análisis del vademécum institucional mediante la aplicación de los Criterios de Beers 2019 y dos escalas de riesgo anticolinérgico para identificar medicamentos potencialmente inapropiados. Posteriormente se realizó un estudio de utilización de los medicamentos identificados, mediante datos de dispensación de farmacia entre el 1 de enero y 31 de diciembre de 2019. El consumo se expresó en Dosis Diarias Definidas por cada 1000 adultos mayores-año (DHD). Resultados: se identificaron 16 medicamentos potencialmente inapropiados, de los cuales los más usados fueron clonazepam (DHD 69), quetiapina (65,6), alprazolam (DHD 43,7), flunitrazepam (DHD 42,7) y zolpidem (DHD 36,4). Conclusiones: la aplicación de herramientas explícitas facilita la identificación de medicamentos potencialmente inapropiados para adultos mayores y se evidenció un consumo elevado de los mismos durante el año 2019 a expensas de derivados benzodiazepínicos y quetiapina.

Introduction: older adults are at higher risk for developing adverse drug reactions. Potentially inappropriate medications are drugs that have more risks than benefits in this age group. There are a number of tools to support the prescription of medication in geriatrics that allow the identification of these medications, and by applying studies developed on the use of medications we may describe or analyze their impact on a given population. Objectives: to recognize availability of potentially inappropriate medications in older adults in ASSE's Metropolitan RAP during 2019 and to draw conclusions about the current situation in terms of the consumption of this kind of medications. Method: an institutional analysis of medications available in each healthcare provided was conducted through the application of Beers Criteria 2019, and two anticholinergic risk scales were used to identify potentially inappropriate medications. Subsequently, the use of the medications identified was studied by applying pharmacy dispensing data between January 1 and December 31, 2019. Consumption was expressed in defined daily doses every 1000 adults per year (DHD). Results: 16 potentially inappropriate medications were identified, the most widely used of which were clonazepam (DHD 69), quetiapine (65.6), alprazolam (DHD 43.7), flunitrazepam (DHD 42.7) and zolpidem (DHD 36.4). Conclusions: Applying explicit tools makes it easier to identify potentially inappropriate medications for older adults. An increased consumption of these kinds of drugs was noticed during 2019, as a result of benzodiazepine derivatives and quetiapine.

Introdução: os idosos são uma população de risco para o desenvolvimento de reações adversas a medicamentos. Medicamentos potencialmente inapropriados são aqueles que apresentam maiores riscos do que benefícios nessa faixa etária. Existem ferramentas de apoio à prescrição em geriatria que permitem identificar esses medicamentos e, por meio da aplicação de estudos de utilização de medicamentos, descrever ou analisar seu uso em uma população. Objetivos: reconhecer a disponibilidade de medicamentos potencialmente inapropriados para idosos na RAP metropolitana da ASSE durante o ano de 2019 e estabelecer um diagnóstico de consumo durante esse ano. Método: o formulário institucional foi analisado utilizando os Critérios de Beers 2019 e duas escalas de risco anticolinérgico para identificar medicamentos potencialmente inapropriados. Posteriormente, foi realizado um estudo de consumo dos medicamentos identificados, através dos dados de dispensação da farmácia entre 1 de janeiro e 31 de dezembro de 2019. O consumo foi expresso em Doses Diárias Definidas por 1000 idosos-ano (DHD). Resultados: foram identificados 16 medicamentos potencialmente inapropriados, sendo clonazepam (DHD 69), quetiapina (65,6), alprazolam (DHD 43,7), flunitrazepam (DHD 42,7) e zolpidem (DHD 36,4) os mais utilizados Conclusões: a aplicação de ferramentas explícitas facilita a identificação de medicamentos potencialmente inapropriados para idosos; foi observado um alto consumo dos mesmos em detrimento dos derivados benzodiazepínicos e da quetiapina durante o período do estudo.

Tromboembolismo pulmonar como posible reacción adversa a Quetiapina Reporte de caso / Pulmonary thromboembolism as a possible adverse reaction to Quetiapine Case report

Resumen Algunos estudios sugieren que existe una relación entre el uso de antipsicóticos y el riesgo de tromboembolismo venoso (TEV) y embolia pulmonar (EP). Sin embargo, los resultados siguen sin ser concluyentes. Se trata del caso de un Masculino de 23 años con antecedentes de Esquizofrenia y Depresión tratado quetiapina 800 mg, el cual es encontrado muerto en la cama de un hotel. En la necropsia sin lesiones traumáticas visibles, hallazgos histológicos de tromboembolismo pulmonar masivo con infartos pulmonares secundarios. Laboratorio de Toxicología detectó la presencia de quetiapina, no se detectó alcohol o drogas de abusos. Mediante el Algoritmo De Karch & Lasagna Modificado el tromboembolismo pulmonar fue una reacción adversa con una probabilidad de relación causal posible. Se han informado muchos casos de muerte súbita causada por EP con la exposición a antipsicóticos, pero la relación de su uso y el riesgo de TEV y EP sigue siendo controvertida.

Abstract Some studies suggest a relationship between antipsychotic use and the risk of venous thromboembolism (VTE) and pulmonary embolism (PE). However, the results remain inconclusive. This is the case of a 23-year-old male with a history of schizophrenia and depression treated with quetiapine 800 mg, who was found dead in a hotel bed. At necropsy with no visible traumatic lesions, histological findings of massive pulmonary thromboembolism with secondary pulmonary infarcts. Toxicology laboratory detected the presence of quetiapine, no alcohol or drugs of abuse were detected. Using the Modified Karch & Lasagna Algorithm, pulmonary thromboembolism was an adverse reaction with a probable causal relationship. Many cases of sudden death caused by PE have been reported with exposure to antipsychotics, but the relationship of their use and the risk of VTE and PE remains controversial.

Prescripción de antipsicóticos de depósito en la policlínica del Hospital Vilardebó / Prescripción de antipsychotics deposito in the polyclinic of the Hospital Vilardebó

Los medicamentos en su formulación de depósito son utilizados como una intervención para la adherencia cuando se dificulta el cumplimiento vía oral. Es frecuente la baja adherencia a los tratamientos por vía oral en las personas con enfermedades crónicas. Se llevó a cabo un estudio observacional, descriptivo de corte transversal, de una muestra aleatorizada de los pacientes que reciben antipsicóticos de depósito, asistidos en la Policlínica del Hospital Vilardebó en el año 2014. El objetivo fue describir las características de la población que tiene prescripto antipsicótico de depósito en la consulta ambulatoria y conocer los hábitos prescriptivos de estos para favorecer su uso racional. La patología psiquiátrica más prevalente fue la esquizofrenia con 56,4 %, donde se usó con más frecuencia la pipotiazina, siendo este más oneroso que el tratamiento con haloperidol y con un perfil de seguridad y efectividad similar. No se encontraron diferencias entre el uso de anticolinérgicos para los efectos extrapiramidales. Más de dos tercios de los pacientes (69,7 %) estuvieron con polifarmacia antipsicótica y un cuarto de los pacientes (24,7 %) con más de 2 antipsicóticos, a pesar de que en las pautas internacionales no recomiendan tratamientos que justifiquen el uso de más de dos antipsicóticos, dado que no existe evidencia que avale esta práctica, además del riesgo aumentado de reacciones adversas. Un bajo porcentaje (20 %) recibió la medicación de depósito todos los meses del año, resultando de vital importancia evaluar en estudios posteriores las causas intervinientes.

Depot formulation drugs are used as an adherence intervention when oral adherence is difficult to achieve. Low adherence to oral drugs is commonly observed in people with chronic diseases. An observational, descriptive, cross-sectional study was carried out on a randomized sample of patients receiving depot antipsychotics, treated at Hospital Vilardebó Outpatient Clinic in 2014. The aim was to describe this population's characteristics and prescription habits at the clinic in order to promote rational use. The most prevalent disorder was Schizophrenia (56.4%); pipothiazine was the most frequently used drug. It is more expensive than haloperidol with similar safety and efficacy profiles. There was no difference in the use of anticholinergic drugs to prevent extrapyramidal side effects. More than two thirds of the patients (69.7%) received antipsychotic polypharmacy and a fourth of the patients (24.7%) received more than two antipsychotics in spite of the fact that international treatment guides do not recommend the use of more than two because of lack of benefit evidence and increased risk of adverse reactions. Only 20 % of the patients received the depot every month of the year, being of vital importance to evaluate in subsequent studies the intervening causes.

Síndrome neuroléptico maligno en un hospital general

Describimos la presentación clínica y dificultades diagnósticas de un caso de síndrome neuroléptico maligno en un hospital general. El paciente fue un varón de 18 años con diagnóstico de retraso mental grave e historia de convulsiones que recibía tratamiento irregular con risperidona y fenitoína. Tras presentar irritabilidad, agresividad y agitación psicomotriz acude a hospital psiquiátrico en donde le indican incremento de dosis de risperidona. Posteriormente por persistencia de agresividad, acude a hospital psiquiátrico en donde se indicó haloperidol, midazolam y levomepromazina, a los pocos días presentó distonía oro mandibular, alza térmica y distonía generalizada con dificultad para la deglución de alimentos, motivo por el cual acudió a hospital general y fue diagnosticado de síndrome neuroléptico maligno. El paciente recibió tratamiento con bromocriptina y diazepam durante hospitalización y tuvo evolución favorable de síntomas neuropsiquiátricos. El síndrome neuroléptico maligno es un evento adverso raro y fatal. Está asociado al uso de psicotrópicos, especialmente antipsicóticos.

We describe the clinical presentation and diagnostic difficulties of a case of Neuroleptic Malignant Syndrome in a general hospital. The patient was an 18-year-old male with severe mental retardation and a history of seizures who received irregular treatment with risperidone and phenytoin. After presenting irritability, aggressiveness, and psychomotor agitation, he went to a psychiatric hospital where received an increase in the dose of risperidone. Subsequently, due to persistence of aggressiveness, he went to a psychiatric hospital where haloperidol, midazolam and levomepromazine were indicated, after few days developed oromandibular dystonia, temperature rise and generalized dystonia with difficulty swallowing food, which is why he went to hospital general and was diagnosed with Neuroleptic Malignant Syndrome. Patient received treatment with bromocriptine and diazepam during hospitalization with favorable evolution of neuropsychiatric symptoms. Neuroleptic Malignant Syndrome is a rare and fatal adverse event. It is associated with the use of psychotropics, especially antipsychotics.

Esquizofrenia asociada a consumo de múltiples sustancias. Responsabilidad profesional / Schizophrenia Associated with Multiple Substance Use

Resumen La esquizofrenia es un trastorno psiquiátrico grave clasificado dentro de los trastornos psicóticos. Los pacientes suelen presentar síntomas variables dependiendo de las 3 dimensiones sintomáticas que padezcan, lo que genera dilación en su apego temprano al tratamiento. El caso clínico de interés a presentar corresponde a un paciente del sexo masculino en la cuarta década de la vida diagnosticado con esquizofrenia asociado al consumo de múltiples sustancias, el cual fue motivo de analizar derivado de los efectos adversos presentados al tratamiento farmacológico posterior a un episodio psicótico. El abordaje farmacológico con pacientes que padecen esta patología debe ir encaminado a contrarrestar los síntomas con base en antipsicóticos y a los efectos adversos causados por los mismos, siempre y cuando la enfermedad sea diagnosticada oportunamente.

Abstract Schizophrenia is a severe psychiatric disorder classified within the psychotic disorders. Patients usually present variable symptoms depending on the three symptomatic dimensions they suffer from, which generates delay in their early adherence to treatment. The clinical case of interest to be presented corresponds to a male patient in the fourth decade of life diagnosed with schizophrenia associated with multiple substance use, which was analyzed due to the adverse effects of pharmacological treatment following a psychotic episode. The pharmacological approach with patients suffering from this pathology should be aimed at counteracting the symptoms based on antipsychotics and the adverse effects caused by them as long as the disease is diagnosed in a timely manner.

Functionality During the First Five Years After the Diagnosis of Schizophrenia. A Cohort Study in a Colombian Population.

OBJECTIVE: There is a lack of studies on the natural history of the initial stages of schizophrenia in Colombia. This study aims to assess functionality in the first five years after the diagnosis of schizophrenia. METHODS: Naturalistic longitudinal study of 50 patients with early schizophrenia evaluated between 2011 and 2014. Data about demographic background, symptoms, introspection, treatment and adverse reactions were collected in all patients every 3 months for at least 3-5 years. Functionality was measured with the Global Assessment of Functioning (GAF) and Personal and Social Performance (PSP) scales. RESULTS: Patients were followed up for a mean of 174±62.5 weeks and showed moderate difficulties in overall functioning. This functioning was modified by polypharmacy, degree of introspection, changes in antipsychotic regimens, and the number of episodes, relapses and hospitalisations. CONCLUSIONS: The results suggest that functional outcomes seem to be related to the use of polypharmacy, degree of insight, changes in antipsychotic regimens, and number of episodes, relapses and hospitalisations during the first years of schizophrenia.
