Prognostic Significance of IL-10 in Childhood Chronic Immune Thrombocytopenic Purpura / 임상소아혈액종양

BACKGROUND: The proposal of the present study was to assess the cytokine imbalances such as serum levels of IL-2, IL-10 and TGF-β1 in childhood chronic ITP during the thrombocytopenic and spontaneous remission phases. The findings of this study are anticipated to offer new insights into the pathogenesis of childhood chronic ITP and the prognostic factors involved in spontaneous remission.METHODS: Ten children with chronic ITP, 6 thrombocytopenic and 4 recovered cases, were enrolled. Five healthy children and eight healthy adults were included in this study as controls. The serum levels of IL-2, IL-10 and TGF-β1 were measured by ELISA technique.RESULTS: During this study, four patients achieved spontaneous remission. The serum level of IL-10 was higher in the patients that recovered spontaneously compared to the patients with persistent chronic thrombocytopenia. The serum level of IL-2 was not able to be detected as the levels were too low for analysis. TGF-β1 showed no significant differences among the groups in this study.CONCLUSION: These data suggest that increased serum level of IL-10 could have prognostic significance in the natural course and long-term outcome of childhood chronic ITP.

Sleep Problems and Daytime Sleepiness in Children with Nocturnal Enuresis

PURPOSE: Nocturnal enuresis (NE) is one of the most common problems in childhood. NE has a multifactorial etiology and is influenced by sleep and arousal mechanisms. The aim of the present study was to prospectively evaluate sleep problems and patterns in children with NE compared with normal healthy controls. METHODS: Twenty-eight children with NE and 16 healthy controls were included in the study. To evaluate sleep habits and disturbances, parents and children filled out a questionnaire that included items about sleep patterns and sleep-related behaviors prior to treatment for NE. Demographic factors and other data were compared for the two groups based on the responses to the sleep questionnaire. RESULTS: Night awakening, sleepwalking, and periodic limb movements were more prevalent in children with NE, but symptoms of sleep-disordered breathing were not increased in this group. There were statistically significant differences in periodic limb movements and daytime sleepiness between the two groups. CONCLUSION: Children with NE seemed to have more sleep problems such as night awakening, sleepwalking, and periodic limb movements. In addition, a higher level of daytime sleepiness and hyperactivity in patients with NE suggested a relationship between NE and sleep disorders.
