Abstract

BACKGROUND:Previous investigations have illustrated that regulated upon activation, normal T-cell expressed and secreted (RANTES) polymorphisms are linked to susceptibility to childhood asthma; nevertheless, the findings continue to be controversial. Accordingly, we conducted the present meta-analysis to clarify the impact of RANTES genetic polymorphisms (-403G/A and -28C/G) on childhood asthma vulnerability. METHODS:A search for published literature was performed using the PubMed, EMBASE, Chinese National Infrastructure, Cochrane Library, Scopus, Web of Science, and WanFang databases and selected in the form of PICOS (participants, interventions, comparisons, outcomes, and study design) to identify all eligible research works. The link between RANTES genetic polymorphisms and childhood asthma susceptibility was evaluated by a pooled odds ratio with a 95% confidence interval. RESULTS:In total, 14 case-control studies were included in the analysis. No significant association existed between risk of childhood asthma and the -403G/A polymorphism subjected to any genetic framework in the overall population. In the stratified analysis, according to ethnicity, the -403G/A polymorphism was linked to augmented vulnerability to childhood asthma in Caucasians (allelic model: odds ratio [OR] = 1.63, 95% confidence interval [CI] = 1.04-2.57, P = .034; codominant model: OR = 2.20, 95% CI = 1.28-3.78, P = .004; dominant model: OR = 1.78, 95% CI = 1.01-3.13, P = .047; and recessive model: OR = 1.92, 95% CI = 1.11-3.30, P = .019). For the stratified analysis by atopic status, the -403G/A polymorphism was linked to augmented childhood asthma in the codominant (OR = 1.39, 95% CI = 1.02-1.91, P = .037) and dominant models (OR = 1.43, 95% CI = 1.02-2.01, P = .037) in atopic asthma. For the -28C/G polymorphism, there was a significant association between childhood asthma and the -28C/G variant (allelic model: OR = 1.33, 95% CI = 1.08-1.65, P = .009; codominant framework: OR = 2.14, 95% CI = 1.47-3.10, P < .001; dominant model: OR = 1.44, 95% CI = 1.07-1.93, P = .017; and recessive model: OR = 2.08, 95% CI = 1.44-3.02, P < .001). Stratified analysis based on ethnicity and the -28C/G polymorphism was linked to augmented vulnerability to childhood asthma in Asian and Caucasian populations. For the subgroup analysis by atopic status, no association was found in atopic and non-atopic asthma. CONCLUSION:The present meta-analysis indicated that the RANTES -403G/A and -28C/G polymorphisms contributed to the development of childhood asthma.

摘要

背景: 以前的研究已经表明,在激活时调节,正常T细胞表达和分泌 (RANTES) 多态性与儿童哮喘的易感性有关; 然而,该发现仍然存在争议。因此,我们进行了本荟萃分析,以阐明RANTES基因多态性 (-403G/A和-28C/G) 对儿童哮喘脆弱性的影响。 方法: 使用PubMed、EMBASE、中国国家基础设施、Cochrane图书馆、Scopus、Web of Science和万方数据库检索已发表的文献,并以PICOS (参与者、干预措施、比较、结果和研究设计) 的形式进行选择,以确定所有合格的研究工作。RANTES基因多态性与儿童哮喘易感性之间的联系通过合并比值比和95% 置信区间进行评估。 结果: 共14个病例对照研究纳入分析。在总体人群中,儿童哮喘风险与任何遗传框架下的-403G/A多态性之间不存在显著关联。在分层分析,不同的人种,-403G/A多态性与增强脆弱性与儿童哮喘白种人 (等位基因型号: 优势比 [OR]  =   1.63,95% 可信区间 [CI]  =   1.04-2.57,P  =  .034; 共显性模型: or = 2.20,95% ci = 1.28-3.78,p =  。004; 优势模型: or =   1.78,95% ci =   1.01-3.13,p   =  。047;和隐性模型: or = 1.92,95% ci = 1.11-3.30,p =.019)。对于特应性状态的分层分析,-403G/A多态性与共显性 (or = 1.39,95% ci = 1.02-1.91,p =.037) 和显性模型 (or = 1.43,95% ci = 1.02-2.01,P =.037) 在特应性哮喘中。对于-28C/G多态性,儿童哮喘与-28C/G变异之间存在显著关联 (等位基因模型: or = 1.33,95% ci = 1.08-1.65,p =  。009; 共显性框架: OR  =   2.14 95% CI  =   1.47-3.10,P < .001; 优势模型: or =   1.44,95% ci =   1.07-1.93,p   =  。017; 隐性模型: or = 2.08,95% ci = 1.44-3.02,p <.001)。基于种族和-28C/G多态性的分层分析与亚洲和高加索人群中儿童哮喘的增加的脆弱性相关。对于特应性状态的亚组分析,在特应性和非特应性哮喘中没有发现关联。 结论: RANTES -403G/A和-28C/G基因多态性与儿童哮喘发病有关。

METHODS::There is emerging evidence for the role of posaconazole in the management of Aspergillus-related cystic fibrosis (CF) lung disease. The tolerability and efficacy of posaconazole in paediatric CF is not well established. We report a prospective study over a fifty-three month period evaluating the safety, tolerability, and efficacy of posaconazole in pediatric CF. Fourteen children (seven males, median age 13 years, range 3-17 years) received a total of twenty-three courses of posaconazole (13 oral suspension and 10 tablet formulation). Of these patient episodes, nine received posaconazole for emerging or active allergic bronchopulmonary aspergillosis (ABPA) and two required a combination of posaconazole and systemic corticosteroids for difficult-to-treat ABPA. A subgroup of patients (n = 12) with persistent isolates of Aspergillus fumigatus, in the absence of serological markers of ABPA, received posaconazole monotherapy for pulmonary exacerbations not responding to conventional broad-spectrum antibiotic treatment. Posaconazole levels, full blood count, electrolytes, and liver function were monitored on day 7 of treatment and then monthly. Posaconazole was well tolerated in all but three patients. Therapeutic plasma levels >1 mg/l were achieved in all receiving the tablet formulation in comparison to 60% on the liquid preparation. There was a modest but significant improvement in FEV1 (% predicted) demonstrated for the cohort as a whole (p = 0.015) following posaconazole therapy. Posaconazole is well tolerated in children as young as six years old, improvements in lung function are observed, and therapeutic plasma levels are readily achieved in patients taking the tablet formulation and in adherent patients taking the liquid formulation.

METHODS::The relationship between the cellular immune response during Trichuris trichiura infection and asthma has not yet been established. In this study, the cytokines interleukin (IL)-2, IL-4, IL-6, IL-10, TNF-α, IFN-γ and IL-17A were evaluated in asthmatic children harboring T. trichiura. For this assessment, asthmatic and non-asthmatic children (ISAAC questionnaire) were submitted to parasitological tests and blood samples were cultured (mitogen stimulation) for cytokine measurements in the supernatant. Asthma frequencies were similar in infected and uninfected children, but IL-4, IL-6, TNF-α and IL-10 levels were high in the infected asthmatic children. Additionally, infected non-asthmatic children exhibited high levels of these cytokines in relation to uninfected non-asthmatic children; however, cytokine levels were lower when compared with infected and asthmatic children. Therefore, T. trichiura infection positively modulated the pro- and anti-inflammatory cytokines in asthmatic children, but a background of asthma seemed to narrow the production of cytokines induced by this helminth.

METHODS::In a recent meta-analysis, we found that atopic diseases, like asthma and allergic rhinitis, occur more frequently prior to the onset of attention-deficit/hyperactivity disorder (ADHD). Our aim was to determine the temporal order of the association between daily fluctuations in atopic disease symptoms and in ADHD symptoms in individual participants. In this observational study among 21 participants, age 7-16 years, we performed a replicated time-series analysis of symptom fluctuations in asthma and/or allergic rhinitis and ADHD. Data were collected through parents who filled in a daily online questionnaire during up to 50 days. In each individual, we investigated the temporal order of fluctuations in atopic disease symptoms and ADHD symptoms using a vector autoregressive (VAR) model while using sleep problems and medication use as covariates. For 16 out of 21 participants, we constructed a VAR model. For a majority of the participants, significant associations were detected between atopic disease symptoms and ADHD symptoms. The results were heterogeneous; the direction, sign, and timing of the relationship between ADHD, atopy, sleep problems, and medication use varied between individuals. This study provides additional evidence that the symptom expression of atopy and ADHD are related. However, the connection between both diseases in children is found to be heterogeneous within our study population.
