Successful Clozapine Rechallenge After Clozapine-Induced Severe Anemia: A Case Report.

INTRODUCTION: Clozapine, a second-generation antipsychotic (SGA), is considered the gold standard medication to treat patients with treatment-resistant schizophrenia (TRS). Despite its efficacy, clozapine is associated with adverse effects, notably neutropenia and agranulocytosis. Other hematological adverse effects are less common. Severe anemia is a rare adverse effect seldom reported in the literature and is typically associated with pure red cell aplasia (PRCA). Nevertheless, the benefits of clozapine in managing TRS make rechallenge a reasonable option. CASE REPORT: We present the case of a 35-year-old man with TRS, resistant to previous antipsychotics, who experienced severe anemia during clozapine treatment. An investigation for clozapine-induced anemia revealed PRCA on myelogram. After discontinuing clozapine, the patient's hemoglobin levels recovered. Subsequent treatments with olanzapine, zuclopenthixol, and aripiprazole proved ineffective, leading us to consider a clozapine rechallenge. The rechallenge, monitored for 58 days, resulted in improved psychiatric symptoms and stable hemoglobin levels. The patient remained stable during 6 months of follow-up, with no hematological changes. DISCUSSION: PRCA is a very rare adverse effect of clozapine. The cause of drug-induced PRCA is still unknown; for clozapine, there are no studies. Rechallenge after a severe and rare adverse effect is a complex decision. This case is the first to report a successful clozapine rechallenge following severe anemia without other blood dyscrasias, emphasizing the imperative need for close monitoring during the rechallenge process. Further study is warranted to understand the predictive factors for a successful outcome in clozapine rechallenges.

Green analytical toxicology method for determination of synthetic cathinones in oral fluid samples by microextraction by packed sorbent and liquid chromatography-tandem mass spectrometry.

PURPOSE: We developed and validated a method for quantitative analysis of ten synthetic cathinones in oral fluid (OF) samples, using microextraction by packed sorbent (MEPS) for sample preparation followed by liquid chromatography‒tandem mass spectrometry (LC‒MS/MS). METHOD: OF samples were collected with a Quantisal™ device and 200 µL was extracted using a C18 MEPS cartridge installed on a semi-automated pipette and then analyzed using LC‒M/SMS. RESULTS: Linearity was achieved between 0.1 and 25 ng/mL, with a limit of detection (LOD) of 0.05 ng/mL and a limit of quantification (LOQ) of 0.1 ng/mL. Imprecision (% relative standard deviation) and bias (%) were better than 11.6% and 7.5%, respectively. The method had good specificity and selectivity against 9 different blank OF samples (from different donors) and 68 pharmaceutical and drugs of abuse with concentrations varying between 400 and 10,000 ng/mL. No evidence of carryover was observed. The analytes were stable after three freeze/thaw cycles and when kept in the autosampler (10 °C) for up to 24 h. The method was successfully applied to quantify 41 authentic positive samples. Methylone (mean 0.6 ng/mL, median 0.2 ng/mL), N-ethylpentylone (mean 16.7 ng/mL, median 0.35 ng/mL), eutylone (mean 39.1 ng/mL, median 3.6 ng/mL), mephedrone (mean 0.5 ng/mL, median 0.5 ng/mL), and 4-chloroethcathinone (8.1 ng/mL) were quantified in these samples. CONCLUSION: MEPS was an efficient technique for Green Analytical Toxicology purposes, which required only 650 µL organic solvent and 200 µL sodium hydroxide, and the BIN cartridge had a lifespan of 100 sample extractions.

Substance use disorders and social functioning from an occupational perspective: a pre and post-study / Transtornos pelo uso de substâncias e funcionamento social sob uma perspectiva ocupacional: um pré e pós estudo

Abstract Introduction Improvements in the social functioning (SF) of people experiencing substance use disorders (SUD) can occur even without use discontinuation. Occupational Therapy (OT) performs multifaceted work on it. Objective This study analyzes the SF of people experiencing SUD before and after treatment and the contributions of OT. Method A pre and post-study before and after starting treatment for SUD in a Psychosocial Care Centre - Alcohol and other Drugs (CAPS-AD) in Brasilia, Brazil - was conducted with 35 clients based on an SF questionnaire. A measure of the participant's SF improvement was defined as the difference between the SF before treatment (SFpre) with the SF after treatment (SFafter). The association between SF and sociodemographic variables/drug/previous treatment was verified by linear regression; all analyses considered a significance level <5%. Results Most of the 35 participants were male (83%), 30-49 years old (77%), attended elementary school (57%), unemployed (57%), single (46%), Black (40%), had been treated previously (60%) and had present alcohol use disorder (46%). Overall, people undergoing treatment significantly improved their SF. Multivariate analysis showed that Whites improved their SF more (mean of 18.8± 10.4) than Pardos/Blacks (10.8± 8.7; 14.1± 6.4), and the improvement in SF was lower for participants who were taking treatment for the first time (10.3± 5.7) compared with those who had previous treatment (17.2± 9.4). Conclusion Treatment in CAPS-AD improved the SF of people experiencing SUD, and the OT professional is a key agent in improving SF due to its performance and approach to clients in vulnerable contexts.

Resumo Introdução Melhorias no funcionamento social (FS) de pessoas com transtornos pelo uso de substâncias (TUS) podem ocorrer mesmo sem descontinuar o uso. A terapia ocupacional realiza um trabalho multifacetado sobre isso. Objetivo Este estudo analisa o funcionamento social das pessoas com transtornos pelo uso de substâncias antes e depois do tratamento e contribuições da terapia ocupacional. Método Um pré e pós-estudo - antes e depois do tratamento para TUS em um Centro de Atenção Psicossocial álcool/drogas (CAPS-AD) em Brasília, Brasil - foi realizado com 35 clientes com um questionário sobre FS. A melhora do FS foi definida como a diferença entre o valor do FS antes (FSpre) e depois do tratamento (FSafter). A associação entre o FS e as variáveis sociodemográficas/drogas/tratamento anterior foi verificada por regressão linear; foi considerado um nível de significância <5%. Resultados A maioria era homens (83%), 30-49 anos de idade (77%), com ensino fundamental (57%), desempregados (57%), solteiros (46%), negros (40%), com tratamento anterior (60%), e apresentavam TU de álcool (46%). Em geral, as pessoas submetidas a tratamento melhoraram significativamente seu FS. A análise multivariada mostrou que os brancos melhoraram mais seu FS (média de 18.8± 10.4) que os Pardos/Negros (10.8± 8.7; 14.1± 6.4), e foi menor entre os que estavam fazendo tratamento pela primeira vez (10.3± 5.7) em comparação com os que o fizeram anteriormente (17.2± 9.4). Conclusão O tratamento no CAPS-AD melhorou o FS das pessoas com TUS, o profissional terapeuta ocupacional é um agente chave para melhorar o FS devido a sua atuação e abordagem em contextos vulneráveis.

High-sensitivity method for the determination of LSD and 2-oxo-3-hydroxy-LSD in oral fluid by liquid chromatography‒tandem mass spectrometry.

PURPOSE: We have developed and validated a high-sensitivity method to quantify lysergic acid diethylamide (LSD) and 2-oxo-3-hydroxy-LSD (OH-LSD) in oral fluid samples using liquid-liquid extraction and liquid chromatography-tandem mass spectrometry (LC‒MS/MS). The method was applied to the quantification of both substances in 42 authentic oral fluid samples. METHODS: A liquid-liquid extraction was performed using 500 µL each of samples (oral fluid samples collected using Quantisal™ device) and dichloromethane/isopropanol mixture (1:1, v/v). Enzymatic hydrolysis was evaluated to cleave glucuronide metabolites. RESULTS: The limit of quantification was 0.01 ng/mL for both LSD and OH-LSD. The linearity was assessed between 0.01 and 5 ng/mL. Imprecision and bias were not higher than 10.2% for both analytes. Extraction recovery was higher than 69%. The analytes were stable in the autosampler at 10 °C for 24 h, and up to 30 days at 4 and -20 °C. The method was applied to the analysis of 42 oral fluid samples. LSD was detected in all samples (concentrations between 0.02 and 175 ng/mL), and OH-LSD was detected in 20 samples (concentrations between 0.01 and 1.53 ng/mL). CONCLUSIONS: A high-sensitive method was fully validated and applied to authentic samples. To our knowledge, this is the first work to report concentrations of LSD and OH-LSD in authentic oral fluid samples.

Psychoactive substances use before suicide: detailed analysis of all cases that occurred in the Brazilian Federal District in a 10-years period.

BACKGROUND: Psychoactive substances (PASs) are an important risk factor for suicide. This study investigated the sociodemographic characteristics, data related to the suicidal behavior, the methods employed, the circumstances of the events, and the use of PASs before dying in all suicides that occurred between 2005-2014 in the Brazilian Federal District, comparing cases with positive and negative detection for PASs in the post-mortem analysis to identify groups at greatest risk. METHODS: A population-based, observational, cross-sectional study with an analytical aspect was conducted with suicides cases collected from local police, which toxicological examination was performed (headspace gas chromatographic-mass spectrometry-HS-GC/MS) for detection of ethanol and methanol in blood samples; immunoassay for other substances (cocaine, marijuana, benzodiazepine). RESULTS: The results showed that the increase in the suicide rate was 10 × greater than the population growth, and 44% of the individuals used PASs before suicide. Individuals are more likely to die by suicide at home, be male, have tried before, and change their behavior days before death; they choose to hang as the method and are influenced by alcohol. CONCLUSION: Identifying what sociodemographic characteristics are associated with a fatal suicide attempt among individuals who use PASs and those who do not use and those who have/do not have mental disorders and what methods are employed could be employed as a path to better interventions. Thus, prevention actions could be planned and directed to individuals with greater risk.

Determination of Drugs of Abuse in Hair by LC-MS-MS: Application to Suicide Attempts Investigation.

Considering that the use of psychoactive substances (PSs) is a risk factor to either higher intensity or frequency of suicidal behavior, hair analysis was conducted to investigate the most consumed PSs (opiates, amphetamine stimulants, marijuana, cocaine and heroin) in patients who attempted suicide and received urgent care at emergency service. Hair samples were extracted using methanol and sonicated under heating and then analyzed using liquid chromatography-tandem mass spectrometry. During validation, the method complied with international recommended criteria, with limits of detection between 0.0025 and 0.05 ng/mg and linearity between 0.1 and 4 ng/mg for methamphetamine, 3,4-methylenedioxymethamphetamine (MDMA), morphine, amphetamine, 6-acetylmorphine, 3,4-methylenedioxyamphetamine (MDA), fenproporex, diethylpropion and codeine; between 0.025 and 1 ng/mg for tetrahydrocannabinol (THC), benzoylecgonine and cocaethylene and between 0.25 and 10 ng/mg for cocaine and mazindol. A total of 109 hair samples were analyzed and segmented in 404 parts. Among all analyzed samples, 30.3% were positive for at least one PS (n = 33), such as cocaine (90.9%), codeine (12.1%), morphine (3.0%), MDMA (3.0%) and THC (3.0%). In segmental analysis of cocaine positive samples (n = 30), 76.7% of the samples indicated recent exposure to cocaine (<1 month). This same behavior was observed when analyzing codeine (n = 4) and morphine (n = 1). THC positive samples indicated exposure dated ∼4 months prior. In conclusion, the method was validated following international recommendations for the 12 most consumed PSs in Brazil, as well as two of the most common found metabolites.

Prevalence of new psychoactive substances (NPS) in Brazil based on oral fluid analysis of samples collected at electronic music festivals and parties.

BACKGROUND: New psychoactive substances (NPS) use is a worldwide public health issue. Knowing the prevalence of NPS guides public health and legal policies to address the problem. The objective of this study was to identify NPS in Brazil through the analysis of oral fluid (OF) samples collected at parties and electronic music festivals. METHODS: Anonymous questionnaires and oral fluid samples were collected from volunteers (≥18 years) who reported the consumption of at least one illicit psychoactive substance in the last 24 h. Oral fluid sample collections occurred at eleven parties and two electronic music festivals over 16 months (2018-2020). Questionnaire answers were matched to oral fluid toxicological results. RESULTS: Of 462 oral fluid samples, 39.2 % were positive for at least one NPS by liquid chromatography‒tandem mass spectrometry (LC-MS/MS). The most prevalent NPS was ketamine (29.4 %), followed by methylone (6.1 %) and N-ethylpentylone (4.1 %); however, MDMA was the most commonly identified (88.5 %) illicit psychoactive substance. More than one drug was identified in 79.9 % of samples, with two (34.2 %) and three (23.4 %) substances most commonly observed. Only 5 % of volunteers reported recent NPS consumption. CONCLUSION: MDMA is still the most common party and electronic music festival drug, although NPS were identified in more than one-third of oral fluid samples.

The relationship between level of education and moral judgment toward who abuse drugs.

The aim of the present study is to verify the differences of the moral judgment toward the people who abuse drugs according to the schooling of the participants. This is the Brazilian part of a multicentric study. N=180 individuals in a community in Brasília, DF, Brazil; following consent, descriptive data were collected by anonymous interviewer-administered questionnaire that included socio-demographic, educational level and the history of drug use. Participants were predominantly females, middle-aged, married, employed, religious, with high school education; higher schooling considered alcohol abusers, marijuana, cocaine and crack are important as anyone else; the majority with lower education level knew someone who used drugs, but no association was found regarding drug use and schooling; in the unadjusted logistic regression model, positive associations were found between higher schooling and 'who use drugs are as important as anyone else' for all drugs studied; after adjusted, the association remained only for marijuana (all p<0.05). The negative attitude surrounding drugs issue can be an important obstacle. The results suggest that education can help to reduce the stigma associated; public policies would be important to minimizing social harm caused by stigmatized visions of drug users.

Quantification of amphetamine and derivatives in oral fluid by dispersive liquid-liquid microextraction and liquid chromatography-tandem mass spectrometry.

The abuse of stimulants such as amphetamine, methamphetamine, ecstasy (MDMA), and their analogues (MDEA and MDA) has been increasing considerably worldwide since 2009. In this work, an analytical method using dispersive liquid-liquid microextraction (DLLME) to determine amphetamine and derivatives in oral fluid samples by liquid chromatography-tandem mass spectrometry (LC-MS/MS) was developed and validated. Linearity was achieved between 20 to 5000 ng/mL (r>0.992, 1/x² weighted linear regression), with a limit of quantification (LOQ) of 20 ng/mL. Imprecision (%relative standard deviation) and bias (%) were not higher than 9.1 and -12.3%, respectively. The matrix effect was lower than 14.6%, with no carryover observed up to 5000 ng/mL and no interference with 10 different oral fluid matrix sources and against 14 pharmaceuticals and other common drugs of abuse. MDMA, MDA, and MDEA in processed samples were stable up to 24 h at autosampler (10°C); and amphetamine and methamphetamine up to 18 h. The developed method was successfully applied to authentic oral fluid analyses (n = 140). The proposed method is an example of the Green Analytical Toxicology, since it reduces both the amount of solvent required in samples preparation and the quantity of solvents and reagents used in analytical-instrumental stage, as well as requires a minimal sample volume, being a cheaper, quicker and more ecological alternative to conventional methods. Obtained results showed that DLLME extraction combined with LC-MS/MS is a fast and simple method to quantify amphetamine derivatives in oral fluid samples.

Screening of 104 New Psychoactive Substances (NPS) and Other Drugs of Abuse in Oral Fluid by LC-MS-MS.

New psychoactive substances (NPS) are a major public health problem, primarily due to the increased number of acute poisoning cases. Detection of these substances is a challenge. The aim of this research was to develop and validate a sensitive screening method for 104 drugs of abuse, including synthetic cannabinoids, synthetic cathinones, fentanyl analogues, phenethylamines and other abused psychoactive compounds (i.e., THC, MDMA, LSD and their metabolites) in oral fluid by liquid chromatography-tandem mass spectrometry (LC-MS-MS). The Quantisal™ oral fluid device was used to collect oral fluid samples. The oral fluid-elution buffer mixture (500-µL sample) was extracted with t-butyl methyl ether, and chromatographic separation was performed on a Raptor™ biphenyl column (100 × 2.1 mm ID, 2.7 µm), with a total run time of 13.5 min. Limits of detection were established at three concentrations (0.05, 0.1 or 1 ng/mL) for most analytes, except for acetyl norfentanyl and mescaline (5 ng/mL). Matrix effects were generally <20% and overall extraction recoveries >60%. The highest matrix effect was observed within the synthetic cannabinoid group (PB22, -55.5%). Lower recoveries were observed for 2C-T (47.2%) and JWH-175 (58.7%). Recoveries from the Quantisal™ device were also evaluated for all analytes (56.7-127%), with lower recoveries noted for 25I-NBOMe, valerylfentanyl and mCPP (56.7, 63.0 and 69.9%, respectively). Drug stability in oral fluid was evaluated at 15, 60 and 90 days and at 25, 4 and -20°C. As expected, greater stability was observed when samples were stored at -20°C, but even when frozen, some NPS (e.g., synthetic cannabinoids) showed more than 20% degradation. The method was successfully applied to the analysis of seven authentic oral fluid samples positive for 17 different analytes. The method achieved good sensitivity and simultaneous detection of a wide range of NPS.

Alcohol and brief intervention for trauma victims.

OBJECTIVE: to describe the causes and severities of trauma in patients who met the criteria for alcohol abuse or dependence according to Mini International Neuropsychiatric Interview, and to display the pattern of alcohol consumption and subsequent changes one year after trauma. METHODS: a transversal and longitudinal quantitative study carried out between November 2012 and September 2013 in the ED. Medical and nursing students collected blood samples, applied the J section of the Mini International Neuropsychiatric Interview (MINI) and submitted alcohol abusers and dependents to BI. One year after admission, patients were contacted and asked about their patterns of alcohol use and their reasons for any changes. RESULTS: from a sample of 507 patients admitted to the ED for trauma, 348 responded to MINI, 90 (25.9%) being abusers and 36 (10.3%) dependent on alcohol. Among the abusers, the most frequent cause of injury was motorcycle accident (35.6%) and among the dependents it was predominantly interpersonal violence (22.2%). Positive blood samples for alcohol were identified in 31.7% of the abusers and 53.1% of the dependents. One year after trauma, 66 abusers and 31 dependents were contacted, and it was ascertained that 36.4% of the abusers and 19.4% of the dependents had decreased alcohol consumption. The main reported reason for the reduction was the experienced trauma. CONCLUSION: the motorcycle accident was the most common cause of injury. The detection of problematic alcohol use and implementation of BI are important strategies in the ED, however for alcohol abusers and dependents, BI was not the most reported reason for any changes in patterns of alcohol use.

[Sexual violence: a descriptive study of rape victims and care in a university referral center in São Paulo State, Brazil]. / Violência sexual: estudo descritivo sobre as vítimas e o atendimento em um serviço universitário de referência no Estado de São Paulo, Brasil.

Rape is a global public health problem, and steps have been taken to encourage studies on the issue and propose interventions for its prevention and appropriate care. This study aimed to characterize the population of female rape victims and describe the characteristics of the sexual assault and the care provided at a university referral center. This was a quantitative retrospective study of care provided to female rape victims from June 2006 to December 2010. The majority of the women (n = 687) were white, single, had no children, with a mean age of 23.7 years and primary to secondary schooling, employed, and practiced a religion. One-fourth of the victims reported no sexual intercourse prior to the sexual assault. Rape occurred mainly at night, on the street, perpetrated by a single stranger, with vaginal penetration, and with threatened or actual force. Most of the victims had reported the rape to someone and felt supported. Early care occurred for almost 90% of women, allowing preventive measures. From 2006 to 2010 there was an increase in the proportion of women that sought help. Better knowledge of the characteristics of this group and the event itself can help improve the structure and functioning of models to assist rape victims.
