Abstract:Objective To investigate the clinical effect of montelukast combined with fluticasone propionate nasal spray on snoring in children.Methods A total of 82 children with snoring were enrolled and divided into observation group and control group. The control group was treated with fluticasone propionate nasal spray, while the observation group was treated with montelukast on the basis of the control group. The overall effective rate was compared between the two groups. The serum levels of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were measured before and after treatment. Polysomnography (PSG) was used to monitor the sleep efficiency, lowest blood oxygen saturation (LSaO2), apnea-hypopnea index (AHI) and micro-arousal index. Obstructive Sleep Apnea-18 (OSA-18) scale was applied to assess the patients' quality of life.Results The overall effective rate of the observation group was higher than that of the control group after treatment (P < 0.05). The differences of IL-6 and TNF-α levels before and after the treatment in the observation group were greater than those in the control group (P < 0.05). The differences of the sleep efficiency, LSaO2, AHI and micro-arousal index before and after the treatment were also greater in the observation group (P < 0.05). As for the patients' quality of life, the observation group showed greater changes in the aspects of the sleep disturbance, emotional distress, daytime problems, physical suffering and caregiver concerns after treatment (P < 0.05).Conclusions Montelukast exhibits synergistic therapeutic effects with fluticasone propionate nasal spray in the treatment of snoring in children. It can not only improve the quality of sleep and life, but reduce the level of inflammatory factors in the patients.
