Cyclosporine Improves Sleep Quality in Patients with Atopic Dermatitis

Introduction Atopic dermatitis (AD) is a chronic, relapsing, inflammatory skin disease characterized by eczema and pruritus, and frequently impairs sleep quality. Although cyclosporine improves symptoms of AD, objective evaluation of sleep in patients with AD treated with cyclosporine has not been reported. This study was conducted to elucidate the effects of cyclosporine on sleep quality for patients with AD. Methods Twelve patients with moderate-to-severe AD were recruited. Nocturnal sleep quality was evaluated for 7 days using a sleep analyzer, which patients wore at the waist before and after cyclosporine was administered at 2.0-4.0 mg/kg per day. Seven parameters of sleep quality were measured before and after cyclosporine administration for a period of 7 days for each patient. Results The administration of cyclosporine significantly improved total sleep time in four cases, sleep latency in two cases, wake after sleep onset in six cases, number of awakenings in two cases, sleep efficiency in seven cases, number of awakenings for more than 8 min in three cases, and number of position changes recorded every 2 min in three cases. The mean values of sleep latency significantly decreased after cyclosporine administration (P = 0.023). The mean value of sleep efficiency significantly increased after the administration (P = 0.002). Conclusion Cyclosporine improves sleep quality in patients with moderate-to-severe AD.
