    Abstract Severe and recurrent infections of the respiratory tract in early childhood constitute major risk factors for the development of bronchial hyper-responsiveness and obstructive respiratory diseases in later life. In the first years of life, the vast majority of respiratory tract infections (RTI) leading to wheezing and asthma are of a viral origin and severity and recurrence are the consequence of a greater exposure to infectious agents in a period when the immune system is still relatively immature. Therefore, boosting the efficiency of the host immune response against viral infections seems to be a rational preventative approach. In the last decades it has been demonstrated that living in farm environments, i.e. early-life exposure to microbes, may reduce the risk of allergic and infectious disorders, increasing the immune response efficacy. These findings have suggested that treatment with bacterial lysates could promote a nonspecific immunomodulation useful in the prevention of recurrent RTIs and of wheezing inception and persistence. Experimental and clinical studies showing the reduction of RTI frequency and severity in childhood and elucidating the involved mechanisms can support this hypothesis.

    Abstract Purpose of review: This article presents recent findings and perspectives on the relationship between early-life respiratory infections and asthma inception, and discusses emerging concepts on strategies that target these infectious agents for asthma prevention.
    Recent findings: Cumulative evidence supports the role of early-life viral infections, especially respiratory syncytial virus and human rhinovirus, as major antecedents of childhood asthma. These viruses may have different mechanistic roles in the pathogenesis of asthma. The airway microbiome and virus-bacteria interactions in early life have emerged as additional determinants of childhood asthma. Innovative strategies for the prevention of these early-life infections, or for attenuation of acute infection severity, are being investigated and may identify effective strategies for the primary and secondary prevention of childhood asthma.
    Summary: Early-life infections are major determinants of asthma development. The pathway from early-life infections to asthma is the result of complex interactions between the specific type of the virus, genetic, and environmental factors. Novel intervention strategies that target these infectious agents have been investigated in proof-of-concepts trials, and further study is necessary to determine their capacity for asthma prevention.

    Abstract Viral respiratory illnesses associated with wheezing are extremely common during early life and remain a frequent cause of morbidity and hospitalization in young children. Although many children who wheeze with respiratory viruses during infancy outgrow the problem, most children with asthma and reductions in lung function at school age begin wheezing during the first several years of life. Whether symptomatic viral infections of the lower respiratory tract are causal in asthma development or simply identify predisposed children remains a controversial issue. Wheezing illnesses caused by respiratory syncytial virus (RSV), particularly those severe enough to lead to hospitalization, have historically been associated with an increased risk of asthma at school age. However, with the development of molecular diagnostics, human rhinovirus (HRV) wheezing illnesses have been recognized more recently as a stronger predictor of school-age asthma than RSV. In this article, the authors review the impact of virus infections during early life, focusing primarily on RSV and HRV, and their potential roles in asthma inception.

    Abstract There is evidence that respiratory viruses play a key role in the development and exacerbation of obstructive respiratory diseases in children. This review attempts to juxtapose the separate profiles and prototypes of pathogenetic mechanisms represented by the two most common amongst such viruses: respiratory syncytial virus (RSV) and human rhinovirus (HRV). RSV represents the most common agent of severe airway disease in infants and young children, and is predominant in winter months. Large epidemiological studies have revealed an unequivocal relationship between RSV infection and subsequent wheezing into childhood, thought to be related to long-term changes in neuroimmune control of the airways rather than allergic sensitisation. HRV is a highly diverse group of viruses that affect subjects of all ages, is ubiquitous and occurs year-round. In contrast to RSV, infections with HRV cause minimal cytotoxicity but induce a rapid production of cytokines and chemokines with amplification of the inflammatory response. The susceptibility to HRV-induced bronchiolitis and subsequent wheezing appears to be linked to individual predisposition since it is often associated with a family or personal history of asthma/atopy. Thus, RSV probably serves as an "inducer" rather than a "trigger". Conversely, HRVs seem to serve as a "trigger" rather than an "inducer" in predisposed individuals.

    Abstract Respiratory tract infections caused by viruses have been implicated in the pathogenesis of asthma. Of these respiratory pathogens, viruses have been demonstrated to be associated with asthma epidemiologically in at least 3 ways ( Fig 1 ). First, during infancy, certain viruses have been implicated in the inception of the asthmatic phenotype. Genetic susceptibility, particularly genes coding for atopic phenotypic characteristics, might differentiate, at least in part, those children who are destined to have persistent wheezing, asthma, or both later in childhood. Second, repeated exposure to infectious viruses in daycare centers or in households with multiple older siblings increases the number of respiratory infections, but in doing so, it might paradoxically reduce the long-term risk of allergies and asthma through either pre-existing or newly formed alterations in cytokine response profiles. Third, in patients with established asthma, particularly children, viral upper respiratory tract infections play a significant role in producing acute exacerbations of airway obstruction that might result in frequent outpatient visits or in hospitalizations. This review will highlight available data on respiratory syncytial virus infections and their relationship to asthma inception in childhood.
