title: [Asthma and the child below 5 years of age: diagnosis and treatment].
abstract: Asthma is the most frequent chronic disease in pediatrics and the increase in its prevalence is a major public health problem. Diagnosis may be difficult in the young child, symptomatology most often occurring following a viral infection. It is important not to ignore a foreign body in the airways or fibrocystic disease and asthma remains, particularly in infants, a diagnosis of elimination. Misdiagnosis or insufficient treatment of asthma may risk the development of irreversible histological lesions and also could compromise pulmonary growth and the child's lung reserve. Spacer devices and nebulisers enable inhaled therapy to be administered to very young children. The value of early diagnosis is to institute appropriate treatment notably in severe asthma with inhaled corticosteroid therapy, the aim being to reduce remodelling lesions of the airways. The minimal effective dose should be defined to minimalise side-effects. The treatment of asthma is not restricted to pharmacotherapy: attempts should be made to reduce intercurrent viral infections, domestic pollution (including smoking) and allergenic concentrations. However, as for all chronic diseases, the clinician will encounter poor compliance. The work of education and support of health professionals is fundamental to the management of asthma.
