Background: To evaluate the health-related quality of life (HRQoL) in patients suffering from narcolepsy.Methods: Subjects included 75 narcoleptic patients diagnosed at the Hephata Klinik, Germany, who met the International Classification of Sleep Disorders (ICSD) criteria for narcolepsy. A standardized telephone interview was used to inquire about the disease and its burdens to the patients. HRQoL was recorded using the 36-item short-form Medical Outcomes Study (SF-36) as well as the Euroqol (EQ-5D). Frequency and factors of influence on decreased HRQoL were evaluated by using bivariate and multivariate analyses.Results: Patients with narcolepsy had considerably lower scores on all eight domains of the SF-36 compared to the general German population. In particular, scores were poor for the dimensions "physical role", "vitality", and "general health perception". Fortyeight percent of the patients reported problems in at least one of the EQ-5D items; most frequent were problems in the dimension "usual activity" (63.8%), "pain/discomfort" (61.7%) and "anxiety/depression" (41.1%). Difficulty maintaining "self-care" was documented only by 6.8%. Themean VAS score was 60.7%. Interestingly, signs and symptoms of narcolepsy, except for irresistible sleep episodes (p < 0.03), had only a minor impact on HRQoL. Multivariate analyses confirmed a strong influence of employment status, living with a partner, excessive daytime sleepiness (EDS) and professional advancement.Conclusions: HRQoL is considerably reduced in patients, with narcolepsy affecting the different dimensions to various degrees. Factors other than clinical signs and symptoms are associated also with poor HRQoL. Measures should be taken to integrate those factors into healthcare guidelines in order to improve the quality of life in patients with narcolepsy. (C) 2007 Published by Elsevier B.V.
