ABSTRACT

ABSTRACT Introduction: Narcolepsy patients have higher prevalence of comorbidities, such as obesity, depression, and pain. Narcolepsy symptoms and concomitant medical conditions can impact the daily activities of patients. The objective of this study is to describe the quality of life in a sample of patients with narcolepsy, and the influence of the nutritional status in health domains. Methods: At Unifesp, two groups of 33 patients (narcolepsy types 1 and 2 meeting 2014 criteria, concerning hypocretin-1) and 33 controls without sleepiness, matched by age and sex, filled out the SF-36. Results: Narcolepsy groups, regardless of their nutritional status, had significantly lower scores in all domains, compared to controls, mainly in Role-physical, Role-emotional, and Energy/Fatigue. Role-physical score was lower in type 1 than in type 2 and controls (37.8±1.0 vs. 50.0±1.2 vs. 85.6±1.6; p<0.0001). Obese with type 2 narcolepsy scored lower than type 1 in physical scales. Conclusion: In a Sleep Center in São Paulo, Brazil, physical and mental health were impaired in narcolepsy types 1 and 2. The first report of the poor health status in Brazilians with narcolepsy type 2 suggests that obesity negatively affects physical domains.


RESUMO Introdução: Pacientes com narcolepsia têm maior prevalência de comorbidades, como obesidade, depressão e dor. Sintomas de narcolepsia e condições médicas concomitantes podem afetar as atividades diárias dos pacientes. O objetivo deste estudo é escrever a qualidade de vida em uma amostra de pacientes com narcolepsia e a influência do estado nutricional nos domínios de saúde. Métodos: Na Unifesp, dois grupos de 33 pacientes (narcolepsia tipos 1 e 2 compatível com os critérios de 2014, em relação a hipocretina-1) e 33 controles sem sonolência, pareados por idade e sexo, preencheram o SF-36. Resultados: Os grupos de narcolepsia, independentemente do estado nutricional, apresentaram pontuações significantemente menores em todos os domínios, comparados aos controles, principalmente nos quesitos físico, emocional e energia/fadiga. A pontuação do critério físico foi menor no tipo 1 do que no tipo 2 e nos controles (37,8±1,0 vs. 50,0±1,2 vs. 85,6±1,6; p<0,0001). Obesos com tipo 2 tiveram pontuação menor do que os com tipo 1 nas escalas físicas. Conclusão: Em um Centro de Sono de São Paulo, Brasil, as saúdes física e mental estavam comprometidas na narcolepsia tipos 1 e 2. O primeiro relato de estado de saúde ruim em brasileiros com narcolepsia tipo 2 sugere que a obesidade afeta negativamente os domínios físicos.

ABSTRACT

This study was thought to characterized clinical and laboratory findings of a narcoleptic patients in an out patients unit at São Paulo, Brazil. METHOD: 28 patients underwent polysomnographic recordings (PSG) and Multiple Sleep Latency Test (MSLT) were analyzed according to standard criteria. The analysis of HLADQB1*0602 allele was performed by PCR. The Hypocretin-1 in cerebral spinal fluid (CSF) was measured using radioimmunoassay. Patients were divided in two groups according Hypocretin-1 level: Normal (N) - Hypocretin-1 higher than 110pg/ml and Lower (L) Hypocretin-1 lower than 110 pg/ml. RESULTS: Only 4 patients of the N group had cataplexy when compared with 14 members of the L group (p=0.0002). DISCUSSION: This results were comparable with other authors, confirming the utility of using specific biomarkers (HLA-DQB1*0602 allele and Hypocretin-1 CSF level) in narcolepsy with cataplexy. However, the HLADQB1*0602 allele and Hypocretin-1 level are insufficient to diagnose of narcolepsy without cataplexy.


Este estudo foi idealizado para avaliar as características clinicas e laboratoriais de uma população de narcolépticos atendidos num centro de referência na cidade de São Paulo (Brasil). MÉTODO: 28 pacientes realizaram polissonografia e teste de múltiplas latências do sono segundo critérios internacionais. O alelo HLADQB1*0602 foi identificado por PCR. A Hipocretina-1 no líquido cefalorradiano (LCR) foi mensurada por radioimunoensaio. Os pacientes foram divididos em 2 grupos conforme o nível de Hipocretina-1. Normal (N) - Hypocretin-1 >110pg/ml e baixa (B) - Hypocretina-1 <110pg/ml. RESULTADOS: Somente 4 pacientes do grupo N tinham cataplexia quando comparados com 14 pacientes do grupo B (p=0,0002). DISCUSSÃO: Estes resultados foram comparáveis com outros autores, confirmando a utilidade do uso de biomarcadores específicos (HLA-DQB1*0602 e nível da hipocretina-1 no LCR) em narcolepsia com cataplexia. Porém, o alelo HLADQB1*0602 e a dosagem da Hipocretina-1 são insuficientes para o diagnóstico da narcolepsia sem cataplexia.

ABSTRACT

Narcolepsy is a sleep disorder characterized by excessive daytime sleepiness, cataplexy, hypnagogic hallucinations, and sleep-onset rapid eye movement (REM) sleep periods. It is now identified as a neurodegenerative disease because there is a massive loss of specific neurons in the brain. These neurons contain the neuropeptides hypocretin-1 and hypocretin-2, which are also known as orexin-A and orexin-B. Cerebrospinal fluid hypocretin-1 measurements are diagnostic for primary narcolepsy. The cause of neural loss could be autoinmune since most patients have the HLA DQB1*0602 alíele that predisposes to the disorders. The discovery of hypocretin deficiency is redefining the clinical entity of narcolepsy and offering novel diagnostic procedures. This article reviews the current understanding of narcolepsy and discusses the implications of hypocretin discovery (Rev Méd Chile 2009; 137:1209-16).
