Official Title: Impact of the Administration of Systemic Glucocorticoids on Inflammatory Response and Clinical Evolution of Patients Diagnosed With Moderate- Severe Bronchiolitis

Brief Summary: The purpose of this study is to to demonstrate that a 7-day course of systemic glucocorticoids decreases the inflammatory activity of moderate or severe bronchiolitis in paediatric patients compared to the standard treatment. To evaluate the morbidity (regarding to the clinical course: Intensive Pediatric Unit Care unit (PICU) admission, mechanical ventilation, ionotropic support, nosocomial infection, rescue therapy for respiratory failure; duration of PICU stay and hospitalization; and exitus) between the treatment and the control groups.

Detailed Summary:

A Prospective, randomised, double blind and placebo controlled study. Patients assigned to experimental group (group 1) will receive iv methylprednisolone 2 mg/kg/day (in two divided doses) and/or oral prednisolone 2,5 mg/kg/day (in two divided doses) every 12 hours, during 7 days.

Patients assigned to control group (group 2) will receive iv/oral glucose 5% solution as placebo, at the same dose and time as the experimental group. A total of 50 (initially 39, but it was extended to 50 by Protocol Amendment) patients per group are recruited.

Bronchiolitis is the most common infection of the lower respiratory tract. It is defined as, the first episode of bronchospasm, dyspnea, expiratory difficulty, feed refusal, tachypnea greater than 50 rpm and radiological evidence of hyperinflation, in less than 24 months.

It is a very prevalent disease, Respiratory syncytial virus (RSV) infects 70% of children under one year and 100% of children under 2 years and generates a major health impact on epidemic period (especially from December to February) . It is the most frequent cause of hospitalization in children under one year during the winter and up to 10% of those admitted will need intensive care, of which up to 60% required intubation and mechanical ventilation. The estimated disease in healthy children, mortality ranges from 0.005% to 0.02%, while in hospitalized children becomes between 1% and 3%.

In recent years, there have been numerous studies, mainly in RSV bronchiolitis, to analyze the immunological basis of the disease, as discussed complex, in order to perform a prophylaxis and treatment of more optimal infection.

Current Primary Outcome:

  • Change from Baseline in inflammatory response [ Time Frame: enrollment to one week treatment ]
    inflammatory response evaluation of the first week of glucocorticoids treatment as assessed by multiple measurements aggregated to arrive at one reported value, which are: the bronchiolitis clinical severity Scale, pediatric mortality Risk scale (PRISM III), the Chest x-ray test, the nasopharyngeal aspiration and analytical exploration (at day 5-7)
  • Morbidity episodes [ Time Frame: 14 months ]
    Morbidity assessment by multiple measurements aggregated to arrive at one reported value which are as follow: necessity of mechanical ventilation, inotropic, presence of nosocomial infection, rescue therapies if respiratory failure occur; days of admission to the Pediatric Intensive Care Unit and hospitalization, in both treatment and control groups


Original Primary Outcome: Same as current

Current Secondary Outcome: Number of Side effects estimate [ Time Frame: 14 months ]

Number of Side effects estimate by comparing the experimental group to the control group


Original Secondary Outcome: Same as current
