When the fever will not stop, stop the pills! A case report

ABSTRACT Neuroleptic malignant syndrome (NMS) is a neurologic emergency potentially fatal. This rare side effect is most commonly associated with first-generation antipsychotics and less frequently with atypical or second-generation antipsychotics. The diagnosis relies on both clinical and laboratory criteria, with other organic and psychiatric conditions being ruled out. CASE REPORT: A 39-year-old female patient, who is institutionalized and completely dependent, has a medical history of recurrent urinary infections and colonization by carbapenem-resistant Klebsiella pneumoniae. Her regular medication regimen included sertraline, valproic acid, quetiapine, risperidone, lorazepam, diazepam, haloperidol, baclofen, and fentanyl. The patient began experiencing dyspnea. Upon physical examination, she exhibited hypotension and a diminished vesicular murmur at the right base during pulmonary auscultation. Initially, after hospitalization, she developed high febrile peaks associated with hemodynamic instability, prompting the initiation of antibiotic treatment. Despite this, her fever persisted without an increase in blood inflammatory parameters, and she developed purulent sputum, necessitating antibiotherapy escalation. The seventh day of hospitalization showed no improvement in symptoms, suggesting NNMS as a differential diagnosis. All antipsychotic and sedative drugs, as well as antibiotherapy, were discontinued, after which the patient showed significant clinical improvement. CONCLUSION: Antipsychotic agents are commonly employed to manage behavioral changes linked to various disorders. However, their severe side effects necessitate a high degree of vigilance, the cessation of all medications, and the implementation of supportive care measures. A prompt and accurate diagnosis of NMS is crucial to alleviating the severe, prolonged morbidity and potential mortality associated with this syndrome.

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.

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 hospitalization, 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.

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.

Introduction: Neuroleptic malignant syndrome (NMS) is uncommon, with an incidence of 0.01% to 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 amisul-pride, 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 leukocy-tosis and elevated CPK. Differential diagnosis 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.

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).

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.

Analysis of prognostic factors in 113 patients with tardive dyskinesia / 中华神经科杂志

Objective:To explore the related factors affecting the prognosis of patients with tardive dyskinesia, in order to find the risk factors of poor prognosis.Methods:A retrospective cohort study was implemented to collect the data of 113 patients with tardive dyskinesia from the movement disorders clinic of the Department of Neurology, Peking Union Medical College Hospital by telephone follow-up. The main variables studied included gender, age, educational level, living environment, job, cigarette smoking, alcohol drinking, hypertension, diabetes, medication type, interval from taking medicine to dyskinesia, course of dyskinesia and intervention measures. The data were analyzed by the statistical software SPSS 25.0. The quantitative data analysis was done by normality test and descriptive statistics, and the qualitative data analysis was done by χ 2 test or Fisher exact probability test. The variables with P≤0.01 in univariate analysis were included in multivariate Logistic regression analysis. Results:Among the 113 patients, 16 patients (14.16%) were cured, 27 patients (23.89%) had obvious improvement, 25 patients (22.12%) had slight improvement, 26 patients (23.01%) had no obvious change, 15 patients (13.27%) had slight deterioration, and 4 patients (3.54%) had obvious deterioration. The good prognosis rate was 60.18%, and the poor prognosis rate was 39.82%. In single factor analysis, the related factors for poor prognosis included age>52 years (χ 2=15.07, P<0.001), educational level in secondary schools and below (χ 2=8.58, P=0.003), physical labor (χ 2=4.66, P=0.031), hypertension (χ 2 = 16.38, P<0.001), diabetes mellitus (χ 2=6.06, P=0.011), dyskinesia caused by first-generation antipsychotics, calcium channel blocker or flupentixol/melitracen tablets ( P<0.001), and the duration of dyskinesia more than 2 years (χ 2 =7.05, P=0.008). Multivariate Logistic regression analysis showed that the independent risk factors for poor prognosis of tardive dyskinesia included hypertension ( OR=3.60, 95% CI 1.17-11.05, P=0.025) and dyskinesia caused by first-generation antipsychotics, calcium channel blocker or flupentixol/melitracen tablets ( OR=3.14, 95% CI 1.21-8.16, P=0.019). Conclusions:Most patients with tardive dyskinesia have a good prognosis. Hypertension and dyskinesia caused by first-generation antipsychotics, calcium channel blocker or flupentixol/melitracen tablets are independent risk factors for poor prognosis.

A prospective study of adverse drug reactions of antipsychotic drugs in a tertiary care public psychiatry hospital

Background: Antipsychotic drugs are commonly used pharmacological agents, which have varied adverse reactions. There is a need to investigate the prevalence of these adverse reactions due to the implications for clinical practice and research. Studies on the prevalence of these adverse reactions are few, especially from Indian subcontinent. Aim and Objectives: The objectives of this study were as follows: (i) To investigate the drug emergent adverse drug reactions (ADRs) in patients who are on antipsychotic drugs and (ii) to study the severity of ADRs due to antipsychotic agents and association between the adverse reaction and the suspected drug. Materials and Methods: This is a prospective observational study, in which 99 patients out of 120 patients suffering with mental illness were enrolled. Base-line investigations such as CBP, ESR, serum creatinine, serum electrolytes, serum cholesterol, serum prolactin, and FBS (fasting blood sugar) were performed and the same were repeated at 1st month and 3rd month and checked for any abnormality. Any suspected ADRs were noted after 1 month and 3 months in patients after starting the treatment with antipsychotic drugs. The patients were assessed with semi-structured interview, the patient rated side effects scale (LUNSERS), and an adverse drug probability scale (Naranjo probability scale). The results were analyzed with SPSS software. The ADRs in patients were also compared between in-patients and out-patients. Results: The atypical drugs particularly risperidone and olanzapine were commonly prescribed for the patients, than typical antipsychotic drugs such as haloperidol. Out of the 99 patients, risperidone was prescribed for 56.6% of patients, olanzapine was prescribed for 40.4% patients, amisulpride was prescribed for 1% of patient, and haloperidol for 2% of patients. About 79% of the patients under study developed ADRs within a month and 21% developed after a month. These drugs were given twice-daily dosage regimen for 89.9% of the patients than once daily dosage regimen, which is 10.1%. Forty-one were in-patients and 58 patients were out-patients. Among the in-patients, risperidone drug was given for 28 (68.3%) patients, olanzapine was given for 11 (26.8%) patients, amisulpride for 1 (2.4%) patient, and haloperidol for 1 (2.4%) patients. The most common ADRs in in-patients was EPS (90.24%) with a statistically significant P < 0.0001. In out-patients, risperidone was prescribed for 28 (48.3%) patients, olanzapine was given for 29 (50%) patients, and haloperidol for 1 (1.7%) patient. The most common ADR among out-patients was sedation (82.75%) with P = 0.0001, which is statistically significant. The ADRs were “significant” according to LUNSERS overall score and are “probable” according to Naranjo’s probability assessment scale. Conclusion: The most common antipsychotic drugs used were risperidone and olanzapine. The common drug emergent adverse reactions were EPS and sedation when the drugs were prescribed twice-daily dosage regimen. The time taken for these ADRs to emerge is ?1 month. The ADRs are significant according to LUNSERS and probable due to suspected drug according to Naranjo’s probability assessment scale. In comparison between in-patients and out-patients, EPS was found more among in-patients and sedation in out-patients. Depending on the intensity of the ADRs, the antipsychotics drug dosage was reduced or drug changed or another was added to combat the ADRs.

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.

Serum levels of megaprolactin and gonadal hormones in patients with hyperprolactinemia induced by antipsychotics and their clinical significance / 中国基层医药

Objective:To investigate serum levels of macroprolactin and gonadal hormones in patients with hyperprolactinemia induced by antipsychotics and their clinical significance.Methods:A total of 105 female patients with schizophrenia who received treatment in Huzhou Third Municipal Hospital from June 2017 to October 2018 were included in this study. All these patients received the antipsychotic drug clozapine for 2 months. Then 50 patients with hyperprolactinemia were included in the observation group, and 55 patients who had no hyperprolactinemia were included in this control group. The scores of the Scale for the Assessment of Negative Symptoms and Scales for the Assessment of Positive Symptoms were compared between the two groups. Serum levels of macroprolactin, progesterone, testosterone, estradiol, prolactin, luteinizing hormone, and follicle-stimulating hormone were then compared between the two groups. The Spearman correlation analysis was used to analyze the correlation between serum macroprolactin level and serum progesterone, estradiol, prolactin, and luteinizing hormone levels.Results:Serum macroprolactin level in the observation group was significantly higher than that in the control group [(63.80 ± 12.13) ng/mL vs. (59.07 ± 9.84) ng/mL, t = 2.20, P = 0.030). Serum levels of progesterone, testosterone, estradiol, prolactin, luteinizing hormone, and follicle-stimulating hormone were (4.01 ± 0.47) ng/mL, (5.59 ± 1.15) ng/mL, (236.72 ± 15.14) pg/mL, (127.30 ± 12.40) ng/mL, (6.05 ± 1.10) mIU/mL, (8.52 ± 2.13) mIU/mL, respectively, and they were (10.25 ± 1.83) ng/mL, (6.01 ± 1.20) ng/mL, (433.10 ± 20.90) pg/mL, (50.58 ± 6.22) ng/mL, (7.69 ± 2.36) mIU/mL, (8.48 ± 2.01) mIU/mL, respectively in the control group. Serum levels of progesterone, estradiol, and luteinizing hormone in the observation group were significantly lower than those in the control group, and serum level of prolactin in the observation group was significantly higher than that in the control group ( t = 23.41, 54.66, 4.63, 40.61, all P < 0.05). There were no significant differences in serum levels of testosterone and follicle-stimulating hormone between the two groups ( t = 1.82, 0.09, P = 0.071, 0.921). Spearman correlation analysis results showed that serum macroprolactin level was negatively correlated with serum levels of progesterone and estradiol, and it was positively correlated with serum levels of prolactin and luteinizing hormone ( r = -0.42, -0.51, -0.68, 0.70, all P < 0.05). Conclusion:Serum levels of macroprolactin and prolactin were higher, and serum levels of progesterone, estradiol, and luteinizing hormone levels were lower in patients with hyperprolactinemia induced by antipsychotics than in patients without hyperprolactinemia. Serum levels of macroprolactin, prolactin, luteinizing hormone, progesterone, and estradiol were remarkably correlated with the balance of gonadal hormones. The study outcomes are of great innovation and science.

Cost-effectiveness analysis and budgetary impact of antipsychotics available in the Brazilian Unified Health System / Análise de custo-efetividade e impacto orçamentário dos antipsicóticos disponíveis no Sistema Único de Saúde brasileiro

Objective: To carry out a cost-effectiveness and budget impact analysis of antipsychotic use in adults to treat schizophrenia from the perspective of the Unified Health System (SUS). Methods: A Markov model simulated the treatment of schizophrenic patients with an initial average age of 25 years and a lifetime horizon. The possibility of combining drugs resulted in 20 pharmacotherapeutic strategies. Results: The lowest-cost strategy, risperidone/olanzapine, obtained values of $45,092.77 with effectiveness of 15.97 QALY. The incremental cost-effectiveness ratio in dollars/QALY of olanzapine/risperidone was 2,470.24, and risperidone/ziprasidone was 352,671.90, compared to the first option. All other therapeutic combinations were dominated. The budgetary impact assessment indicated that the most cost-effective choice could generate savings of US$ 1,555.00 on average, per patient, over five years. Conclusion: The therapeutic proposal with the lowest cost per patient was risperidone combined with olanzapine, revealing these two drugs as a strategy with lower budgetary impact and better cost-effectiveness.

Health-related quality of life in patients treated with atypical antipsychotics

Objective: To assess health-related quality of life and associated factors in patients treated with atypical antipsychotics, as well as to determine utility values using the EuroQol-5D-3L instrument. Methods: A cross-sectional study was conducted at a state-run pharmacy in the Brazilian National Health System. Individuals were included if they were using a single atypical antipsychotic and completed the EuroQol-5D-3L. Sociodemographic, behavioral, and clinical data were collected. The dependent variable was the EuroQol-5D-3L utility score. Associations between the independent variables and the dependent variable were analyzed in a multiple linear regression model. Results: A total of 394 patients were included, and their mean utility score was 0.664±0.232. Patients treated with clozapine had the highest mean score (0.762 [0.202]), followed by olanzapine (0.687 [0.230]), risperidone (0.630 [0.252]), ziprasidone (0.622 [0.234]), and quetiapine (0.620 [0.243]). The following variables were related to higher utility scores: income, employment, clozapine use, no illicit psychoactive substance use, no suicide attempts, and no comorbidities. Conclusion: Evaluating health-related quality of life differences in the available atypical antipsychotics can facilitate the choice of treatment, improve health outcomes, and ensure rational prescriptions.

Diabetes mellitus asociada al uso crónico de antipsicóticos atípicos / Diabetes mellitus association with chronic use of atypical antipsychotics

Resumen Los agentes antipsicóticos son considerados como el principal tratamiento farmacológico para el manejo de mantenimiento y el tratamiento de casos agudos de la esquizofrenia y otros trastornos mentales. Estos medicamentos están clasificados en dos grupos: los antipsicóticos de primera generación o antipsicóticos típicos (AT) y los antipsicóticos de segunda generación o antipsicóticos atípicos (AA). En relación con el uso de los antipsicóticos típicos (AT), se han descrito importantes efectos adversos, sobre todo síntomas extrapiramidales (EPS), lo cual ha relegado su uso y fomenta el mayor empleo en la práctica clínica de los antipsicóticos atípicos (AA) gracias a la adecuada efectividad clínica demostrada hasta el momento. Sin embargo, estos medicamentos están asociados con diferentes alteraciones metabólicas, entre las cuales se encuentra un mayor riesgo de diabetes; para lo cual se han propuesto varios mecanismos etiopatogénicos. En esta revisión narrativa, se presenta un resumen actualizado de la literatura de los últimos 5 años sobre el uso de antipsicóticos atípicos y la diabetes mellitus tipo 2, haciendo énfasis en las diferentes hipótesis reportadas hasta el momento que involucran el aumento de peso y diferentes efectos mediados por hormonas, receptores de neurotransmisores y neuropéptidos que impactan en la génesis de los estados hiperglucémicos y de insulinorresistencia.

Abstract Antipsychotic agents are currently considered as the main pharmacological treatment that helps the maintenance management of acute schizophrenia and other mental disorders. These drugs are classified into two groups: First-generation antipsychotics (FGAs) or typical antipsychotics, and Second-generation antipsychotics (SGAs) also known as atypical antipsychotics (AAP). In relation to the use of typical antipsychotics, some relevant adverse effects have been described, especially in terms of extrapyramidal side effects (EPS), which has downgraded their use and encourages the treatment of atypical antipsychotics (AAP) due to the adequate clinical effectiveness demonstrated so far in the practice. However, these drugs have been associated with different metabolic alterations such as the increased risk of suffering from diabetes; thus, several etiopathogenic mechanisms have been proposed. In this narrative review, we seek to present an updated summary of the literature of the last five years about the use of atypical antipsychotics and type 2 diabetes mellitus. Here it has been emphasized the different hypotheses reported so far that involve weight gain and different effects mediated by hormones, neurotransmitter receptors, and neuropeptides that impact on the genesis of hyperglycemia and insulin resistance states

RESUMEN Los objetivos del estudio fueron determinar la variabilidad de costos de antipsicóticos en establecimien tos farmacéuticos públicos (hospitales) y privados (farmacias y clínicas), calcular la variabilidad de cos tos de antipsicóticos entre establecimientos y estimar el costo de tratamiento mensual de mantenimiento con antipsicóticos. Se realizó un estudio de análisis de costos, los costos unitarios de los antipsicóticos se obtuvieron del Observatorio Peruano de Productos Farmacéuticos. Los resultados muestran que la va riabilidad de costos de los antipsicóticos fue mayor en farmacias y clínicas que en hospitales, y el análisis de variabilidad de costos entre establecimientos farmacéuticos mostró que el costo de un antipsicótico en una farmacia y clínica fue 1,3 a 140 veces y de 2,8 a 124 veces, respectivamente, el costo que tuvo el fármaco en un hospital. El costo de tratamiento mensual de mantenimiento varió de S/ 3 a S/ 2130 según el fármaco y establecimiento farmacéutico.

ABSTRACT The objectives of the study were to determine the cost variability of antipsychotics in public (hospi tals) and private pharmaceutical establishments (pharmacies and clinics), calculate the cost variability of antipsychotics between establishments and estimate the cost of monthly maintenance treatment with antipsychotics. A cost analysis study was performed, unit costs of antipsychotics were obtained from the Peruvian Pharmaceutical Products Observatory. The results show that the cost variability of antipsycho tics was greater in pharmacies and clinics than in hospitals, and the analysis of cost variability between pharmaceutical establishments showed that the cost of an antipsychotic in a pharmacy and clinic was 1.3 to 140 times and 2.8 to 124 times, respectively, the cost of the drug in a hospital. The cost of monthly maintenance treatment varied from S/3 to S/2130 according to the drug and pharmaceutical establish ment.

Agranulocitosis inducida por clozapina / Clozapine-induced agranulocytosis

RESUMEN Clozapina, actualmente, sigue siendo el gold standard para la esquizofrenia resistente al tratamiento, pero solo bajo un adecuado monitoreo hematológico, porque está asociada a agranulocitosis. Clozapina se metaboliza produciendo N-desmetilclozapina (farmacológicamente activa), el N-óxido de clozapina (inactivo) y especies reactivas de oxígeno (ion nitrenio). El recuento de neutrófilos <1000 células/mm3 corresponde a un estado de neutropenia. La agranulocitosis es un estado grave de neutropenia con un recuento absoluto de neutrófilos <500 células/mm3. Clozapina se asocia con la agranulocitosis en aproximadamente el 0,8 % de los pacientes, y el riesgo aumenta con la edad y en mujeres. Existen dos mecanismos que explican la agranulocitosis inducida por clozapina: inmunológico (respuesta mediada por el sistema inmunitario contra neutrófilos haptenizados) y tóxico (por acción de los metabolitos N-desmetilclozapina y ion nitrenio). La farmacogenética es una herramienta valiosa para conseguir la referida medicina personalizada, al adaptar e individualizar el tratamiento basado en los marcadores genéticos de cada paciente. Numerosos estudios han demostrado una asociación potencial de la agranulocitosis inducida por clozapina con ciertos haplotipos HLA (HLA-B38, DR4, DQw3, DQB1). Luego que un paciente ha presentado agranulocitosis, se conocen tres mecanismos de reexposición a clozapina: simple, con litio y con factores estimuladores de colonias de granulocitos. Debido al riesgo de agranulocitosis, las formulaciones de clozapina están disponibles solo a través de una distribución controlada, con un registro detallado de los pacientes y con una farmacovigilancia sistematizada y obligatoria.

ABSTRACT Clozapine currently remains the gold standard for treatment-resistant schizophrenia, but only under an adequate hematological monitoring, because it is associated with agranulocytosis. Clozapine is metabolized to produce pharmacologically active N-desmethylclozapine, inactive clozapine N-oxide and reactive oxygen species (nitrenium ion). A neutrophil count < 1000 cells/mm3 corresponds to a state of neutropenia. Agranulocytosis is a severe state of neutropenia with an absolute neutrophil count < 500 cells/mm3. Clozapine is associated with agranulocytosis in approximately 0.8 % of the patients, with an increased risk in older people and women. There are two mechanisms that explain the clozapine- induced agranulocytosis: immunological (response mediated by the immune system against haptenized neutrophils) and toxic (by the action of the metabolites N-desmethylclozapine and nitrenium ion). Pharmacogenetics represents a valuable tool to achieve the so-called personalized medicine by adapting and individualizing the treatment based on the genetic markers of each patient. Several studies have shown a potential association of clozapine-induced agranulocytosis with certain HLA haplotypes (HLA-B38, DR4, DQw3 and DQB1). After a patient has presented agranulocytosis, three mechanisms of clozapine rechallenge are known: simple, with lithium and with factors that stimulate granulocyte colonies. Due to the risk of agranulocytosis, clozapine formulations are available only through a controlled distribution, with a detailed record of the patients, and with a mandatory and systematized pharmacovigilance.

Abstract Objective To assess the quality and sleep time between public health network users and associated factors. Methods A cross-sectional study of 775 individuals of both genders in a city in the Center-West region of Brazil. A semi-structured questionnaire was used to assess the sociodemographic characteristics, life habits, health conditions, binge drinking, and quality and sleep duration assessed by the Pittsburgh Sleep Quality Index. Poisson regression was used to identify the factors associated with poor sleep quality and sleep duration (short and long). Results In the multiple analysis, the factors associated with poor sleep quality were female gender (prevalence ratio: 1.10, 95% Confidence Interval and 95%CI 1.05-1.16, p <0.00), binge drinking (prevalence ratio: 1.08; 95%CI 1.03-1.13; p <0.01), illegal drug use (prevalence ratio: 1.06, 95%CI 1.00-1.12, p=0.03), angina (prevalence ratio: 1.07, 95%CI 1.03-1.18, p <0.01) and depression (prevalence ratio: 1.07 95%CI 1.00-1.14, p=0.02). Obesity was associated with short sleep duration (prevalence ratio: 1.10 95%CI 1.02-1.17, p <0.01). Age> 55 years was associated with long sleep duration (prevalence ratio: 1.39; 95%CI: 1.00-1.92; p=0.04). Conclusion Being a woman, being over 55 years old, consuming alcoholic beverages, using illegal substances, angina, obesity and depression were risk factors for changes in quality and sleep duration. The results of the present study reinforce the need for the development of actions aimed at the prevention of diseases related to sleep disorders in the study population.

Síndrome neuroléptico maligno inducido por risperidona y facilitado por sepsis de origen urinario: clínica y fisiopatología / Malignant neuroleptic syndrome induced by risperidone and facilitated by sepsis of urinary origin: clinical aspects and physiopathology

La risperidona es un antagonista selectivo monoaminérgico, con una elevada afinidad por receptores dopaminérgicos, que puede producir síndrome neuroléptico maligno (SNM), considerado una emergencia médica con alto riesgo de muerte. Tiene una incidencia de hasta el 3% y su mortalidad está entre el 10 y 20%. Se reporta el caso de una paciente de 56 años, que reunía los criterios clínicos del SNM, inducido por el uso de risperidona y facilitado por una sepsis de origen urinario. El tratamiento se condujo con un agente agonista dopaminérgico y cambio del antipsicótico, procedimientos que resultaron en una adecuada evolución clínica. El SNM es una entidad de baja prevalencia, para la cual existen criterios diagnósticos con especificidad y sensibilidad mayor del 90%, por lo que debe diferenciarse claramente de otras patologías. Se discute el mecanismo mediante el cual la infección urinaria facilitaría la ocurrencia de esta enfermedad. El diagnóstico precoz mejora la respuesta al manejo adecuado que se establezca en cada caso.

Risperidone is a selective monoaminergic antagonist with a high affinity for dopamine receptors that can cause neuroleptic malignant syndrome (NMS), considered a life-threatening medical emergency. It has an incidence of up to 3% and its mortality is between 10 and 20%. The case of a 56-year-old female who met the clinical criteria of NMS, induced by the use of risperidone and facilitated by a sepsis of urinary origin, is reported. It was managed with a dopamine agonist and the change of antipsychotic, which resulted in a favorable clinical course. The NMS is a low-prevalence entity whose diagnosis has specificity and sensitivity greater than 90%, reason for which must be clearly differentiated from other pathologies. The mechanism by which urinary infection could facilitate the occurrence of this disease is discussed. Early diagnosis improves the response to an adequate management to be established in each case.
