Filter by:The primary objective of this study is to assess the efficacy of motavizumab compared to placebo when administered monthly to preterm infants during their first RSV season for the reduction of the incidence of serious early childhood wheezing from their 2nd through 3rd birthdays.
This is a retrospective cohort study of children included in a large medical insurance claims database.
GER and respiratory symptoms are both common phenomenon in children. Both can coexist in the same patient by chance alone. Research reveals increased incidence for both to coexist leading to suspect a temporal association and possible causality. Therefore we conducted an observational study To determine the primary cause (RS or GER)using for the first time both PH-Impedance as measurements of GER and Wheezy monitoring (WEEM) that records simultaneously wheeze and cough noises. Both modalities will be recorded for 12-24 hours. If GER precedes cough/wheeze recordings it points to GER being the possible precipitating factor and vice versa.
Infants will be enrolled into this study in one of three groups. First, there will be a group of full term infants with no history of wheezing. Second, there will be a group of infants receiving a ct scan that is non-respiratory related. Third, there will be a group of infants that are born full term but have a history of wheezing of at least 3 episodes. The three groups will be compared to see if there is a difference in lung function, lung structure and lung size. Besides comparing the testing results we will be evaluating environmental and inherited characteristics. There are 2 purposes of this study. The first purpose is: To determine whether asymptomatic groups of infants at high risk for wheezing (Environmental tobacco smoke (ETS) exposure, Fm Asthma, male Gender) have fixed or reversible airway narrowing. The second purpose of this study is: To determine the relative contributions of fixed and reversible airway narrowing in infants with recurrent symptomatic wheezing, and to determine whether fixed and reversible airway narrowing is related to ETS exposure, Fm Asthma, and male Gender.
We can not predict which wheezing child younger than 3 years of age benefits from systemic glucocorticoid and which one does not. It is not known whether the differences in the efficacy are related to the differences in viral etiology, atopy, immunogical maturity or age of the patient. The study aims to answer the following questions: 1. What is the viral etiology of acute childhood expiratory wheezing? 2. What is the efficacy of prednisolone in relation to age, atopy and viral etiology in acute childhood wheezing? 3. Does prednisolone treatment increase risk for secundary bacterial infection in acute childhood expiratory wheezing? 4. What is the significance of inflammatory markers in predicting the efficacy of systemic steroid or patient outcome in acute childhood expiratory wheezing? Study will follow randomized, double blind, placebo-controlled parallel design. Study will start in Septemper 2000 and will be performed at the Department of Pediatrics, Turku University Hospital, Turku Finland. The study population will be 300 hospitalized wheezing children aged 3 months – 15 years. Investigational drug will be prednisolone, first dose 2 mg/kg, then 2 mg/kg/d/3 (max. 60 mg/vrk) p.o. for 3 d and comparative drug will be placebo tablet similar to investigational drug with the equal dosage. The primary outcome will be the time until ready for discharge. The study will provide new and important information for the diagnostics, treatment, disease outcome and prevention of acute childhood expiratory wheezing.
