Aim

To compare high-flow oxygen therapy (HFOT) with continuous positive airway pressure (CPAP) in children with bronchiolitis aged < 24 months, using treatment failure, length of stay (LOS) in the paediatric intensive care unit (PICU), and adverse events as outcomes.

Methods

Systematic literature search was conducted using PubMed and Scopus until March 13, 2024. Data from prospective and retrospective studies comparing HFOT to CPAP were incorporated in the random-effects meta-analysis model. The results for treatment failure were presented as risk ratios (RRs) with 95% confidence intervals (95% CIs), and those for LOS in the PICU as mean differences (MD) with 95% CIs.

Results

Eight studies fulfilled the inclusion criteria, and one study was found by manual search. Treatment failure was less often associated with CPAP than with HFOT (RR: 0.65; 95% CI: 0.51–0.81). Instead, LOS in the PICU did not differ (standardised MD: −0.10; 95% CI: −0.27 to 0.06). Adverse events were minor being associated more often with CPAP.

Conclusion

Both HFOT and CPAP were safe for treating bronchiolitis, but CPAP showed a lower risk of treatment failure. Our results can be generalized to those treated in the PICU.

目的:比较高流量氧疗(HFOT)与持续气道正压通气(CPAP)治疗老年毛细支气管炎儿童的疗效。方法:系统检索PubMed和Scopus的文献,截止到2024年3月13日。比较HFOT和CPAP的前瞻性和回顾性研究的数据被纳入随机效应荟萃分析模型。治疗失败的结果以95%置信区间(95% ci)的风险比(rr)表示,PICU内LOS的结果以95% ci的平均差异(MD)表示。结果:8项研究符合纳入标准,人工检索到1项研究。治疗失败与CPAP的相关性低于与HFOT的相关性(RR: 0.65; 95% CI: 0.51-0.81)。相反,PICU的LOS没有差异(标准化MD: -0.10; 95% CI: -0.27至0.06)。不良事件较少,与CPAP相关的发生率更高。结论:HFOT和CPAP治疗毛细支气管炎均安全,但CPAP治疗失败的风险较低。我们的结果可以推广到PICU的治疗。

Aim: Bacterial meningitis, including meningococcal meningitis, poses a significant global health threat for children. This study aimed to identify the key reasons why parents accepted meningococcal vaccines. It also wanted to promote wider meningococcal vaccination efforts.

Methods: A cross-sectional study was conducted with the parents of children who visited a university hospital's paediatric outpatient clinic in Turkey between 20 August 2015 and 30 May 2016. The parents provided sociodemographic information and responded to a questionnaire about the meningococcal conjugate vaccination (MCV), based on the Health Belief Model.

Results: The parents of 302 children (52.3% girls), with a mean age of 6.77 ± 4.77, participated in the study. Mothers accounted for 80.1%. Sociodemographic factors, including the parents' education and the mother's occupation, were significant factors in accepting the vaccine. So were recognizing the severity of the disease and the perceived susceptibility and risks. Vaccine uptake also increased if the parents received concise and timely information from doctors. However, some parents were uncomfortable with the number of injections their children would receive and larger families were also a barrier.

Conclusion: Factors that affected parents' acceptance of the MCV included sociodemographic factors, awareness of the severity of the disease and perceived susceptibility and risks.

目的:细菌性脑膜炎,包括脑膜炎球菌性脑膜炎,对全球儿童的健康构成重大威胁。本研究旨在确定家长接受脑膜炎球菌疫苗的关键原因。它还希望促进更广泛的脑膜炎球菌疫苗接种工作。方法:对2015年8月20日至2016年5月30日在土耳其某大学医院儿科门诊就诊的儿童家长进行横断面研究。父母提供了社会人口学信息,并根据健康信念模型回答了关于脑膜炎球菌结合疫苗接种(MCV)的问卷。结果:302例患儿家长参与研究,其中女孩占52.3%,平均年龄(6.77±4.77)岁。母亲占80.1%。社会人口因素,包括父母的教育程度和母亲的职业,是影响接受疫苗的重要因素。认识到疾病的严重程度以及感知到的易感性和风险也是如此。如果父母从医生那里得到简明及时的信息,疫苗接种率也会增加。然而,一些家长对孩子接受注射的次数感到不舒服,而大家庭也是一个障碍。结论:影响家长接受MCV的因素包括社会人口学因素、对疾病严重程度的认识以及对易感性和风险的认知。

Aim

We aimed to investigate if the incidence of type 1 diabetes increased in children during the SARS-CoV-2 pandemic and whether SARS-CoV-2 antibodies were more frequently present at diagnosis compared with healthy individuals. We also examined whether clinical characteristics and coexisting autoimmunity differed between SARS-CoV-2 antibody positive and negative individuals.

Methods

This retrospective, longitudinal observational study included children aged 0–17 years diagnosed with type 1 diabetes between 01 January 2018 and 31 December 2023 at Skåne University Hospital, Sweden. Blood samples were analysed for SARS-CoV-2 antibodies and islet autoantibodies and compared to analyses of healthy children from the same period. Clinical characteristics and thyroid autoimmunity at onset were collected from medical records.

Results

The incidence of type 1 diabetes increased from 40/100.000 (pre-pandemic) to 53/100.000 (pandemic). Children diagnosed with type 1 diabetes more likely tested positive for SARS-CoV-2 nucleocapsid protein (NCP) antibodies compared to healthy children. The SARS-CoV-2-NCP positive group had a higher prevalence of thyroid autoimmunity compared to the SARS-CoV-2-NCP negative group.

Conclusion

The incidence of type 1 diabetes increased during the SARS-CoV-2 pandemic, with a possible connection to COVID-19. Interestingly, children positive for SARS-CoV-2 antibodies at type 1 diabetes diagnosis had a higher likelihood of thyroid autoimmunity compared to children negative for SARS-CoV-2 antibodies.

目的:我们旨在调查在SARS-CoV-2大流行期间儿童中1型糖尿病的发病率是否增加,以及与健康个体相比,诊断时是否更频繁地出现SARS-CoV-2抗体。我们还研究了SARS-CoV-2抗体阳性和阴性个体的临床特征和共存的自身免疫是否存在差异。方法:这项回顾性、纵向观察研究纳入了2018年1月1日至2023年12月31日在瑞典sk大学医院诊断为1型糖尿病的0-17岁儿童。对血液样本进行SARS-CoV-2抗体和胰岛自身抗体分析,并与同期健康儿童的分析进行比较。从医疗记录中收集临床特征和发病时甲状腺自身免疫。结果:1型糖尿病发病率由流行前的40/10万上升至流行前的53/10万。与健康儿童相比,诊断为1型糖尿病的儿童更有可能检测出SARS-CoV-2核衣壳蛋白(NCP)抗体呈阳性。与SARS-CoV-2-NCP阴性组相比,阳性组甲状腺自身免疫患病率更高。结论:SARS-CoV-2大流行期间1型糖尿病发病率上升,可能与COVID-19有关。有趣的是,在1型糖尿病诊断中,SARS-CoV-2抗体阳性的儿童与SARS-CoV-2抗体阴性的儿童相比,甲状腺自身免疫的可能性更高。

Aim

This study evaluated if oral support with techniques to support the infant's jaw to promote sucking could improve the exclusive breastfeeding rate in full-term infants born small-for-gestational-age (SGA).

Methods

This was an observational study with a prospective cohort and a historical control. SGA infants born in 2023–2024 who received oral support were compared to those born in 2020–2021 who did not. The primary outcome was the exclusive breastfeeding rate at 7–10 days of life. Secondary outcomes were the exclusive breastfeeding rate at discharge, the maximum weight loss, the time to regain birthweight, the occurrence of transient and/or persistent hypoglycaemia and the length of hospitalisation.

Results

We analysed 146 infants: 73 received oral support and 73 did not. Infants who received oral support had an exclusive breastfeeding rate when returning to the hospital at day 7–10 that was significantly higher than infants who did not (54.8% vs. 37.0%, p = 0.03). Exclusive breastfeeding at discharge, at a median (interquartile range) age of 3 (2–4) days, was similar between groups. No differences were found in the secondary outcomes.

Conclusion

Oral support appeared useful in promoting exclusive breastfeeding in full-term SGA infants. Further research could assess if the intervention maintained exclusive breastfeeding over time.

目的:本研究评估口腔支持技术支持婴儿颌部促进吸吮是否能提高小胎龄足月婴儿的纯母乳喂养率。方法:这是一项前瞻性队列和历史对照的观察性研究。将2023-2024年出生的接受口腔支持的SGA婴儿与2020-2021年出生的未接受口腔支持的婴儿进行比较。主要结果是出生后7-10天的纯母乳喂养率。次要结局是出院时的纯母乳喂养率、最大体重减轻、恢复出生体重的时间、一过性和/或持续性低血糖的发生以及住院时间。结果:我们分析了146名婴儿:73名接受了口头支持,73名没有。接受口服支持的婴儿在第7-10天返回医院时的纯母乳喂养率显著高于未接受口服支持的婴儿(54.8% vs. 37.0%, p = 0.03)。出院时纯母乳喂养,年龄中位数(四分位数范围)为3(2-4)天,各组之间相似。次要结果没有发现差异。结论:口腔支持有助于促进SGA足月儿纯母乳喂养。进一步的研究可以评估干预是否在一段时间内保持纯母乳喂养。

Aim

Bronchopulmonary dysplasia (BPD) is a major cause of morbidity and impaired growth in preterm infants. This study compared the incidence of grade 2–3 BPD in infants predominantly fed with mother's own milk (MOM) or pasteurised donor milk (PDM) and examined associations between nutrition and BPD severity.

Methods

Prospective single-centre study including infants < 32 weeks' gestation admitted between January 2023 and June 2024. Infants were classified by predominant feeding type (> 50% MOM or PDM) and BPD severity (no BPD/1 or BPD 2–3). Nutritional intake, feeding tolerance, fortification timing and growth were analysed.

Results

Of 158 infants, 88 (56%) received > 50% MOM and 70 (44%) > 50% PDM. BPD 2–3 occurred in 27 (17.1%) infants with no significant group difference (19% vs. 14%, p = 0.41). Feeding intolerance (44% vs. 11%, p < 0.01), delayed fortification (12.5 vs. 7.0 days, p < 0.01), and later enteral feeding (12.0 vs. 6.0 days, p < 0.01) were associated with BPD 2–3.

Conclusion

No significant difference in BPD 2–3 incidence was found between MOM and PDM groups. Feeding intolerance, delayed fortification, and slower enteral transition were independent risk factors for grade 2–3 BPD.

目的:支气管肺发育不良(BPD)是早产儿发病和生长受损的主要原因。本研究比较了主要以母乳喂养(MOM)或巴氏供体奶(PDM)喂养的婴儿2-3级BPD的发病率,并研究了营养与BPD严重程度之间的关系。方法:前瞻性单中心研究,包括50% MOM或PDM的婴儿和BPD严重程度(无BPD/1或BPD 2-3)。分析营养摄取量、摄食耐受性、强化时间和生长情况。结果:158例婴儿中,88例(56%)接受> 50% MOM治疗,70例(44%)接受> 50% PDM治疗。27例(17.1%)婴儿发生BPD 2-3,组间差异无统计学意义(19% vs. 14%, p = 0.41)。喂养不耐受(44% vs. 11%, p)结论:MOM组和PDM组BPD -3发生率无显著差异。喂养不耐受、延迟强化和较慢的肠内过渡是2-3级BPD的独立危险因素。

Aim

Most children with Hodgkin lymphoma (HL) survive today, yet about 50% experience long-term complications. This study evaluated health-related quality of life (HRQoL) in survivors of childhood HL.

Methods

Two different HRQoL-instruments, the EuroQoL 5-Dimension 5-Level (EQ-5D-5L) and Patient-Reported Outcomes Measurement Information System (PROMIS) questionnaires, were sent to all individuals aged 0–18 and diagnosed with HL in Sweden and Finland from 2005 to 2019.

Results

A total of 135 of 377 survivors responded to the survey. The mean EQ-5D-5L index was 0.933 ± 0.11 and the EuroQoL Visual Analogue Scale (EQ-VAS) score averaged 75.1 ± 17.6. Females reported lower scores than males on the EQ-5D-5L index (p = 0.007) and EQ-VAS (p = 0.022), as well as more problems within the PROMIS-domains for physical function (p = 0.016), fatigue (p < 0.001), anxiety (p < 0.001), and depression (p = 0.002). Both EQ-5D-5L index and PROMIS T-scores for all assessed domains were comparable with the general population, including differences between sexes. Our analysis indicated that an EQ-VAS cut-off of ≤ 85 effectively identified 90%, or more, of the individuals reporting problems in the PROMIS domains for fatigue, anxiety and depression.

Conclusion

Survivors of childhood HL report a good HRQoL. The EQ-VAS may serve as a useful, simple screening tool for detecting survivors in need of psychosocial interventions.

目的:大多数儿童霍奇金淋巴瘤(HL)存活至今,但约50%经历长期并发症。本研究评估儿童HL幸存者的健康相关生活质量(HRQoL)。方法:2005年至2019年,向瑞典和芬兰所有年龄在0-18岁、诊断为HL的患者发放两种不同的hrqol工具,即EuroQoL 5维5级(EQ-5D-5L)和患者报告结果测量信息系统(PROMIS)问卷。结果:377名幸存者中有135人回答了调查。EQ-5D-5L指数平均值为0.933±0.11,EuroQoL视觉模拟量表(EQ-VAS)评分平均值为75.1±17.6。女性报告的EQ-5D-5L指数(p = 0.007)和EQ-VAS (p = 0.022)得分低于男性,并且在身体功能(p = 0.016)和疲劳(p)的承诺域中出现更多问题。结论:儿童HL幸存者报告的HRQoL良好。EQ-VAS可以作为一种有用的、简单的筛选工具,用于发现需要社会心理干预的幸存者。

Aim

Skin-to-skin contact (SSC) is a key aspect of infant- and family-centred developmental care and should be initiated as early as possible after birth. This study aimed to assess the effects of early SSC, within the first 3 days of life, compared to late SSC, from Day 4 onwards, in very preterm infants. It also explored parents' experiences of SSC.

Method

Data were collected over 10 years, from 2014 to 2024, via an online parental survey created by parent associations and the French National Neonatal Society. We analysed only responses from parents of infants born before 32 weeks' gestation.

Results

A total of 2212 responses were analysed. Findings revealed that 98% of parents who began SSC early believed it occurred at the right time, while 30% of those who started later felt it was too late. Parents who practised early SSC were more likely to report comfortable SSC during the hospital stay, with an adjusted odds ratio of 1.64 (95% confidence interval: 1.14–2.37). Key factors contributing to a positive SSC experience included support from nursing staff, a secure setting, privacy and a comfortable chair.

Conclusion

Early SSC was highly valued by parents of very preterm infants.

目的:皮肤对皮肤接触(SSC)是婴儿和家庭为中心的发展护理的一个关键方面,应在出生后尽早开始。本研究旨在评估早期SSC的影响,在生命的前3天内,与晚期SSC相比,从第4天起,在早产儿中。并探讨了家长在南南合作中的体验。方法:通过父母协会和法国国家新生儿协会创建的在线父母调查,从2014年到2024年,收集了10多年的数据。我们只分析了孕32周前出生婴儿的父母的回答。结果:共分析了2212份回复。调查结果显示,98%的早期开始SSC的父母认为它发生在正确的时间,而30%的晚开始的父母认为为时已晚。早期实施SSC的家长更有可能在住院期间报告舒适的SSC,调整后的优势比为1.64(95%置信区间:1.14-2.37)。促进积极的SSC体验的关键因素包括护理人员的支持、安全的环境、隐私和舒适的椅子。结论:早期SSC受到极早产儿家长的高度重视。

Aim

This study aimed to compare providers' ratings of delivery and fidelity of a post-natal extended home visiting programme within Child Health Services for visits conducted in families' homes versus the clinic setting.

Methods

A retrospective quantitative study based on questionnaires (n = 3028) from child health services nurses and social workers was conducted using non-parametric tests to determine if there were any differences in professionals' perceptions of programme delivery and/or quality.

Results

The results from this study indicate significant differences in professionals' perceptions of fidelity, confidence in abilities, content coverage, alliance-building, and emotional climate between home and clinic visits, with higher ratings given in all areas for visits conducted in the home.

Conclusion

While clinic visits may offer certain logistical advantages for professionals and primary care clinics, they may not provide the optimal environment for delivering the programme with fidelity, which is necessary for achieving the desired outcomes for child health and family well-being. The findings need to be taken into consideration when making decisions about resource allocation for early childhood programmes aimed at equitable health for a more sustainable society.

目的:本研究旨在比较儿童健康服务机构在家庭与诊所进行的产后延伸家访计划的提供者对分娩和保真度的评分。方法:采用非参数检验对来自儿童保健服务护士和社会工作者的问卷(n = 3028)进行回顾性定量研究,以确定专业人员对方案交付和/或质量的看法是否存在差异。结果:本研究结果显示,专业人员在家访视与诊所访视在保真度、能力信心、内容覆盖、联盟建立、情绪氛围等方面的认知均有显著差异,在家访视在所有领域的评分均较高。结论:虽然诊所访问可能为专业人员和初级保健诊所提供一定的后勤优势,但它们可能无法为忠实执行方案提供最佳环境,而忠实执行方案是实现儿童健康和家庭福祉的预期结果所必需的。在决定为旨在促进更可持续社会的公平保健的幼儿方案分配资源时,需要考虑到这些调查结果。

Bronchiolitis (The Snotty Lung): Prevention Is Likely to Be More Helpful Than a ‘Cure’ 毛细支气管炎(流鼻涕的肺):预防可能比“治疗”更有帮助。
IF 2.1 4区 医学 Q1 PEDIATRICS Pub Date : 2025-11-26 DOI: 10.1111/apa.70384
Mark L. Everard
<p>In 1963, Reynolds and Cook observed that <i>oxygen is vitally important</i> (in the treatment of acute bronchiolitis) <i>and there is little evidence that any other therapy is consistently or even occasionally useful</i> [<span>1</span>] and this still holds true more than 60 years later. In the study by Loveys et al. published in this issue [<span>2</span>] the authors address the suggestion that the macrolide antibiotic, azithromycin, may reduce the severity of the acute illness and the prevalence of subsequent respiratory symptoms. They concluded <i>‘</i>There is insufficient evidence to support the use of azithromycin as part of hospital care for infants with bronchiolitis<i>’</i>. While none of the included studies individually found evidence to support the use of macrolides, the initial meta-analysis suggested that it may have a small effect on the length of stay. However, in their sensitivity analysis, which involved removing the studies that reported longer durations of stay than the authors felt were typical for Australasia [<span>2</span>], this apparent effect disappeared.</p><p>Azithromycin joins an extensive list of potential therapies which fell by the wayside when subject to more rigorous testing. These include ‘asthma therapies’ such as β-agonists, corticosteroids, theophylline, anti-cholinergics and a leukotriene antagonist; antibiotics and antivirals and approaches to improve airways clearance including inhaled hypertonic saline and physiotherapy. Despite the evidence, adherence to guidelines is frequently poor as illustrated by the two Australasian studies in which non-macrolide antibiotics were used in 60%–70% of patients. The rationale for using a macrolide antibiotic in these studies was based on having anti-inflammatory, immunomodulatory and anti-viral effects [<span>2</span>]. Macrolides appear to have a role in downregulating neutrophilic inflammation and, as noted by Loveys et al., the airways inflammation in bronchiolitis is dominated by neutrophils. The use of azithromycin has become ubiquitous, particularly in adult respiratory medicine, largely because of its perceived anti-inflammatory effects (even though, as in these studies, it is used at doses that have antibacterial activity). The downside of using this convenient ‘magic bullet’ so widely is, of course, the fact that macrolides are extremely effective in driving antimicrobial resistance [<span>3</span>].</p><p>Every paediatrician knows what ‘acute bronchiolitis’ looks like when they see it, but there is no universally agreed definition. There is no definitive test for the condition, and the diagnosis is based on a cluster of signs [<span>4</span>]. The studies included in the review allow subjects to have crackles and/or wheeze as a sign of airways obstruction. Crackles are generally observed in young infants (< 6 months) and represent the snapping opening of alveolar units. Secretions in the airways and mucosal oedema are almost certainly responsible for
1963年,Reynolds和Cook观察到氧气是至关重要的(在急性细支气管炎的治疗中),几乎没有证据表明任何其他治疗方法都是持续有效的,甚至偶尔有效。60多年后,这一观点仍然成立。在Loveys等人发表于本期b[2]的研究中,作者提出大环内酯类抗生素阿奇霉素可能降低急性疾病的严重程度和随后呼吸道症状的患病率。他们得出结论:“没有足够的证据支持将阿奇霉素作为毛细支气管炎婴儿医院护理的一部分。”虽然纳入的研究中没有单独发现支持大环内酯类药物使用的证据,但最初的荟萃分析表明,它可能对住院时间有很小的影响。然而,在他们的敏感性分析中,包括删除报告的停留时间比作者认为的澳大拉西亚bbb的典型停留时间更长的研究,这种明显的影响消失了。阿奇霉素加入了众多潜在疗法的行列,这些疗法在接受更严格的测试时被搁置了。其中包括“哮喘疗法”,如β激动剂、皮质类固醇、茶碱、抗胆碱能药和白三烯拮抗剂;抗生素和抗病毒药物以及改善气道清除率的方法包括吸入高渗盐水和物理治疗。尽管有证据,但澳大利亚的两项研究表明,对指南的遵守往往很差,其中60%-70%的患者使用了非大环内酯类抗生素。在这些研究中使用大环内酯类抗生素的基本原理是基于其具有抗炎、免疫调节和抗病毒作用b[2]。大环内酯类药物似乎具有下调中性粒细胞炎症的作用,正如Loveys等人所指出的,毛细支气管炎的气道炎症以中性粒细胞为主。阿奇霉素的使用已经变得无处不在,特别是在成人呼吸系统医学中,主要是因为它被认为具有抗炎作用(尽管在这些研究中,它的使用剂量具有抗菌活性)。当然,广泛使用这种方便的“灵丹妙药”的缺点是,大环内酯类药物在推动抗菌素耐药性方面非常有效。每个儿科医生在看到“急性细支气管炎”时都知道它是什么样子,但没有一个普遍认可的定义。对于这种情况没有明确的测试,诊断是基于一组体征。本综述中包括的研究允许受试者有噼啪声和/或喘息作为气道阻塞的迹象。裂纹通常在婴儿(6个月)中观察到,代表肺泡单位的破裂。气道中的分泌物和粘膜水肿几乎肯定是远端气道关闭的原因。对于较大的婴儿和学步儿童,气道较大,完全关闭远不常见。然而,分泌物和粘膜水肿仍然会导致血流受限,从而产生喘息(所有的喘息都不是哮喘)。因此,相同的炎症模式可能导致两种不同的临床表现:一种是噼啪声,一种是喘息声。第三种常见的声音是由呼吸道分泌物发出的咔嗒声,尽管吸气和呼气的声音都很刺耳,但它通常被误认为是喘息声。相反,伴随喘息的病毒感染可由两种不同的病理生理过程引起,因为气流受限也可由气道平滑肌收缩引起,这是哮喘的典型特征。哮喘似乎是气道平滑肌体内平衡的获得性丧失,其患病率随着年龄的增长而增加,直至生命的早期。相比之下,由病毒引起的无支气管收缩的中性粒细胞炎症(细支气管炎)引起的明显气流阻塞的发生率在学龄前逐渐下降。因此,在学龄前,有明显病毒感染的喘息儿童队列将包含两种类型的患者,哮喘的比例随着年龄的增长而增加。纳入临床无法区分的哮喘患者和非哮喘患者,可以解释在“学龄前喘息”治疗研究中观察到的相互矛盾的结果。诸如皮质类固醇之类的药物是否有帮助取决于哮喘和毛细支气管炎患者的比例。Loveys等人表示,他们的目的是“综合阿奇霉素对患有或因细支气管炎住院的婴儿(12个月大)的疗效和安全性的证据”,大概是为了确保绝大多数患有细支气管炎。有趣的是,在他们的研究中,只有两项研究只招募12个月以下的婴儿,其他5项研究的招募年龄分别为18个月或24个月。 第三种常见的学龄前呼吸道疾病是持续性细菌性支气管炎,尽管这些患者即使在急性发作期间也很少到医院就诊。他们不喘息,但在那些有ruttle,家长通常报告这是喘息。鉴于急性细支气管炎在绝大多数情况下是一种相对短暂的自限性疾病,人们可能会质疑是否有可能找到一种对临床病程有显著影响的治疗方法。正如Lovey等人所指出的,高质量护理的本质包括良好的支持性护理。补充氧气有助于防止可能导致疲惫和最终死亡的剧烈躁动。这种躁动通常在婴儿的饱和度降到80度以上时变得明显。不幸的是,在那些医疗基础设施欠发达的国家,死亡率仍然很高,据估计,全世界的死亡人数达到数十万人。因此,在这些环境中,防止病情恶化的干预措施将是非常宝贵的,即使在发达国家,鉴于每年冬天收治的大量病人,这种干预措施也将是有价值的。这种干预是否可能的答案可能在于我们对这种情况的病理生理学的理解。纳入试验的受试者几乎总是住院,代表了受影响最严重的患者亚组。即使对于这些患者,据广泛报道,住院时间的中位数为两到三天,几乎没有机会对病程产生影响。此外,有证据表明,至少对于RSV来说,病毒滴度和中性粒细胞数量在入院前后再次达到峰值,这使得它很难对随后的病程产生显著影响。如果发现一种药物可以安全地减轻疾病的严重程度,很可能需要在发生下气道阻塞之前给药,这是一个具有挑战性的前景。在纳入系统评价的研究中,有三项研究要求确定RSV为急性疾病的病因。其中一项是基于一种信念,即早期严重的呼吸道合胞病毒感染在引起哮喘方面具有独特的作用。这个想法在近70年前首次提出,一度几乎无处不在,但现在基本上已被抛弃。RSV是毛细支气管炎入院的最常见原因,可能是由于它能够损害有效长期免疫的发展。因此,年龄最小的婴儿的被动获得性免疫相对较差,而年龄最小的婴儿(1-6个月)最有可能经历最严重的下呼吸道感染,这在很大程度上是由于导气管直径相对较小。奇怪的是,许多临床医生现在支持这样的建议,即人类犀牛病毒在引起哮喘的能力方面是独一无二的!其余四项研究包括临床诊断为“细支气管炎”的患者,而不考虑病毒状态。未发现病毒的患者比例在26%至60%之间变化。这些研究者大概接受了这样一种观点:不管病毒是什么,潜在的病理生理都是相似的。证据是所有的呼吸道病毒都会诱导嗜中性粒细胞流入呼吸道上下呼吸道都是如此。因此,急性细支气管炎可以被认为是“流鼻涕的肺”,类似于患有尿路感染的人流鼻涕的鼻子。气道阻塞不像哮喘那样主要是由于平滑肌收缩。研究表明,在患有细支气管炎的婴儿样本中发现一种以上的病毒并不罕见,而且两种或两种以上病毒的存在似乎与更严重的疾病无关。相比之下,一项对幼儿园学龄前儿童的研究发现,感冒时鼻分泌物的数量和脓量在那些有潜在致病菌[8]的儿童中要大得多。在患有急性细支气管炎的婴儿中也发现了类似的结果,这表明获得新病毒的影响受到宿主微生物群[5]的强烈影响。我们对常驻微生物组在影响急性和慢性气道疾病表现中的作用的理解仍处于非常初级的阶段,尤其是因为在下气道中进行研究非常困难。此外,患有疾病和没有疾病的人的气道微生物谱的差异似乎是一个连续体的一部分,在健康和疾病之间没有明确的区分。最近的随机对照试验表明,与单克隆制剂[10]一样,母体接种RSV疫苗可提供显著的住院保护。 未来几年,这些干预措施对入院人数的影响将会很有趣,因为其他病毒可能会填补部分空缺,也许更重要的是,如果所有婴儿都得到保护(尽管他们只占人口的很小一部分),面对越来越大的变异压力,突变的可能性会开始出现。即使有了这些预防性干预措施,诊断和管理细支气管炎的挑战也不会消失。本期发表的系统综述有助于强调围绕毛细支气管炎这种常见疾病的许多争议和挑战,以及在幼儿中将流鼻涕的肺与病毒和哮喘区分开来的挑战。马克·埃弗拉德:构思,写作-原稿,写作-审查和

Everard","doi":"10.1111/apa.70384","DOIUrl":"10.1111/apa.70384","url":null,"abstract":"&lt;p&gt;In 1963, Reynolds and Cook observed that &lt;i&gt;oxygen is vitally important&lt;/i&gt; (in the treatment of acute bronchiolitis) &lt;i&gt;and there is little evidence that any other therapy is consistently or even occasionally useful&lt;/i&gt; [&lt;span&gt;1&lt;/span&gt;] and this still holds true more than 60 years later. In the study by Loveys et al. published in this issue [&lt;span&gt;2&lt;/span&gt;] the authors address the suggestion that the macrolide antibiotic, azithromycin, may reduce the severity of the acute illness and the prevalence of subsequent respiratory symptoms. They concluded &lt;i&gt;‘&lt;/i&gt;There is insufficient evidence to support the use of azithromycin as part of hospital care for infants with bronchiolitis&lt;i&gt;’&lt;/i&gt;. While none of the included studies individually found evidence to support the use of macrolides, the initial meta-analysis suggested that it may have a small effect on the length of stay. However, in their sensitivity analysis, which involved removing the studies that reported longer durations of stay than the authors felt were typical for Australasia [&lt;span&gt;2&lt;/span&gt;], this apparent effect disappeared.&lt;/p&gt;&lt;p&gt;Azithromycin joins an extensive list of potential therapies which fell by the wayside when subject to more rigorous testing. These include ‘asthma therapies’ such as β-agonists, corticosteroids, theophylline, anti-cholinergics and a leukotriene antagonist; antibiotics and antivirals and approaches to improve airways clearance including inhaled hypertonic saline and physiotherapy. Despite the evidence, adherence to guidelines is frequently poor as illustrated by the two Australasian studies in which non-macrolide antibiotics were used in 60%–70% of patients. The rationale for using a macrolide antibiotic in these studies was based on having anti-inflammatory, immunomodulatory and anti-viral effects [&lt;span&gt;2&lt;/span&gt;]. Macrolides appear to have a role in downregulating neutrophilic inflammation and, as noted by Loveys et al., the airways inflammation in bronchiolitis is dominated by neutrophils. The use of azithromycin has become ubiquitous, particularly in adult respiratory medicine, largely because of its perceived anti-inflammatory effects (even though, as in these studies, it is used at doses that have antibacterial activity). The downside of using this convenient ‘magic bullet’ so widely is, of course, the fact that macrolides are extremely effective in driving antimicrobial resistance [&lt;span&gt;3&lt;/span&gt;].&lt;/p&gt;&lt;p&gt;Every paediatrician knows what ‘acute bronchiolitis’ looks like when they see it, but there is no universally agreed definition. There is no definitive test for the condition, and the diagnosis is based on a cluster of signs [&lt;span&gt;4&lt;/span&gt;]. The studies included in the review allow subjects to have crackles and/or wheeze as a sign of airways obstruction. Crackles are generally observed in young infants (&lt; 6 months) and represent the snapping opening of alveolar units.
