AVALIAÇÃO DAS NECESSIDADES DOS FAMILIARES DE VÍTIMAS DE TRAUMA CRANIOENCEFÁLICO

Objetivo: identificar as necessidades dos familiares de vítimas de Trauma Cranioencefálico atendidas ambulatorialmente e avaliar quantitativamente o atendimento dessas necessidades. Método: estudo descritivo de abordagem quantitativa. Foram utilizados dois instrumentos de coleta, um para caracterização do familiar e da vítima e outro o Family Need Questionnaire em sua versão adaptada para o português aplicados com 22 familiares. Resultados: a grande maioria (93,1%) das necessidades elencadas foi considerada “importante ou muito importante” e estão relacionadas aos subtemas "informações sobre saúde" e “suporte profissional”. Conclusão: as taxas de atendimentos das necessidades apontadas pelos familiares demonstram a qualidade do serviço oferecido pelos profissionais de saúde durante o tratamento e reabilitação das vítimas de Trauma Cranioencefálico. Descritores: Traumatismos Encefálicos; Família; Relações Familiares

The Absence of CYP3A5*3 Is a Protective Factor to Anticonvulsants Hypersensitivity Reactions: A Case-Control Study in Brazilian Subjects

<div><p>Although aromatic anticonvulsants are usually well tolerated, they can cause cutaneous adverse drug reactions in up to 10% of patients. The clinical manifestations of the antiepileptics-induced hypersensitivity reactions (AHR) vary from mild skin rashes to severe cutaneous drug adverse reactions which are related to high mortality and significant morbidity. Genetic polymorphisms in cytochrome P450 genes are associated with altered enzymatic activity and may contribute to the risk of AHR. Here we present a case-control study in which we genotyped SNPs of CYP2C19, 2C9 and 3A5 of 55 individuals with varying severities of AHR, 83 tolerant, and 366 healthy control subjects from São Paulo, Brazil. Clinical characterization was based on standardized scoring systems and drug patch test. All <i>in vivo</i> investigation followed the ENDA (European Network of Drug Allergy) recommendations. Genotype was determined by real time PCR using peripheral blood DNA as a template. Of all 504 subjects, 65% were females, 45% self-identified as Afro-American, 38% as Caucasian and 17% as having non-African mixed ascendancy. Amongst 55 subjects with AHR, 44 had severe cutaneous drug adverse reactions. Of the 46 drug patch tests performed, 29 (63%) were positive. We found a strong association between the absence of CYP3A5*3 and tolerant subjects when compared to AHR (<i>p = 0</i>.<i>0002</i>, <i>OR = 5</i>.<i>28 [CI95% 2</i>.<i>09–14</i>.<i>84]</i>). None of our groups presented positive association with CYP2C19 and 2C9 polymorphisms, however, both SNPs contributed to separation of cases and tolerants in a Classification and Regression Tree. Our findings indicate that drug metabolism genes can contribute in the tolerability of antiepileptics. CYP3A5*3 is the most prevalent CYP3A5 allele associated with reduced enzymatic function. The current study provides evidence that normal CYP3A5 activity might be a protective factor to aromatic antiepileptics-induced hypersensitivity reactions in Brazilian subjects.</p></div
