Epidemiologic data suggest strong links between hospitalisation with bronchiolitis in infancy and subsequent higher risk of developing lower respiratory tract infections (LRTI) and/or hyperreactive airway diseases. The aim of this study was to evaluate in an Italian population the natural history of respiratory diseases in children hospitalised for LRTI when they were <2 years.
An observational, perspective, longitudinal study was performed through telephone interviews. Nine pediatric tertiary care centres participated to the study evaluating a population of 187 children, hospitalised in the previous year (November 1999-April 2000) for bronchiolitis or pneumonia when they were <2 years of age and participated to a previous study on the prevalence of infant LRTI in Italy (RADAR).
Twenty-three (12.3%) children had a gestational age <36 weeks. In the 12 months following the first hospitalisation, an elevated frequency of respiratory symptoms was found. Indeed, 152 (81.3%) children suffered from not-requiring-hospital-admission respiratory infections and 21 (11.2%) were hospitalized again for LRTI: 11.6% had bronchiolitis, 23.5% bronchitis and 35.2% pneumonia. In addition, 1.2% had gs;3 infectious episodes and 21.4% gs;6: 68 (36.4%) showed wheezy bronchitis and 17 (9.1%) were reported to have asthma; 132 children (71%) took antibiotics during the last year, 19.4% >3 times; 111 (59.4%) bronchodilators and 49 (26.2%) oral corticosteroids. One year after the first hospitalisation, 19 subjects (10.2%) were found to be positive to at least one class of allergens by prick test or RAST.
Thus, the demonstration of a high morbidity rate for LRTI, wheezing and asthma in this study group during the first year follow-up after hospital admission further support the need for prophylactic interventions to reduce the morbidity and severity of sequelae of LRTI, in particularly in premature children and/or with additional risk factors.
流行病学数据表明,婴儿期因细支气管炎住院与随后发生下呼吸道感染(LRTI)和/或高反应性气道疾病的较高风险之间存在密切联系。本研究的目的是在意大利人群中评估2岁以下因LRTI住院的儿童呼吸系统疾病的自然病程。
通过电话访谈进行了一项观察性、前瞻性、纵向研究。九个儿科三级护理中心参与了该研究,评估了187名儿童,这些儿童在前一年(1999年11月至2000年4月)因细支气管炎或肺炎住院,当时他们年龄小于2岁,并且参与了之前关于意大利婴儿LRTI患病率的研究(RADAR)。
23名(12.3%)儿童的胎龄小于36周。在首次住院后的12个月内,发现呼吸道症状的发生率较高。事实上,152名(81.3%)儿童患有无需住院治疗的呼吸道感染,21名(11.2%)因LRTI再次住院:11.6%患有细支气管炎,23.5%患有支气管炎,35.2%患有肺炎。此外,1.2%有≥3次感染发作,21.4%有≥6次;68名(36.4%)表现为喘息性支气管炎,17名(9.1%)被报告患有哮喘;132名儿童(71%)在去年使用了抗生素,19.4%使用次数超过3次;111名(59.4%)使用了支气管扩张剂,49名(26.2%)使用了口服皮质类固醇。首次住院一年后,通过点刺试验或RAST发现19名受试者(10.2%)对至少一类过敏原呈阳性。
因此,本研究组在住院后第一年随访期间LRTI、喘息和哮喘的高发病率证明,进一步支持了采取预防性干预措施以降低LRTI后遗症的发病率和严重程度的必要性,特别是在早产儿和/或有其他危险因素的儿童中。
