Colorado Clinical Proteomics Program 1. Pediatric Lung Disease 2. Hypothesis and Specific Aims 3. Colorado Clinical Proteomics Program - Organization - Setting - Cores - Networks - Special Features Colorado Clinical Proteomics Program
Childhood Adult Lung Disease Morbidity Mortality Lung Disease Protein Biomarkers - Assessment difficult - Non-invasive sampling - Small volume specimens Pediatric Lung Disease Asthma, Bronchopulmonary Dysplasia, Cystic Fibrosis, Pulmonary Artery Hypertension Colorado Clinical Proteomics Program
Asthma Reversible Airway Obstruction Pediatric Asthma - 10-35% of all children - Quality of Life, School Attendance - Morbidity, Hospitalization 4/1000 - Mortality - Cost (Sennhauser et al, 2005; Engelsvold, Omyar, 2003; Myers, 2000) Colorado Clinical Proteomics Program
Bronchopulmonary Dysplasia (BPD) - 0.2% to 1% newborns (10,000-40,000/yr) - 60% Readmission rate - Increasing rate of premature births - Surfactant - Decreased severity - No change in Incidence • BPD • Chronic Lung Disease • Preterm Infants • Mechanical Ventilation • All Lung Components (Wen et al, 2004) Colorado Clinical Proteomics Program
Cystic Fibrosis (CF) - 17,000 Children - 20% Hospitalized - Progressive Loss Of Lung function - Median age of Death (25 years) - Cost • Cystic Fibrosis • Genetic • Failure of • Airway Defense (CF Foundation Patient Registry 2003, Bethesda, MD) Colorado Clinical Proteomics Program
Pulmonary Arterial Hypertension (PAH) • PAH • CHD • Idiopathic • Developmental • Abnormalities • Mortality – 10 year 40% • Morbidity • Prolonged hospitalizations • 240 followed at Colorado (Yung et al, 2004) Colorado Clinical Proteomics Program
Clinical Proteomics Potential • Asthma BPD CF PAH • Population screening Yes • Susceptibility • Staging • Rapid progression study study • Exacerbation • - Identification • - Susceptibility study • Response to tx study study • Toxicity with tx • Clin Trial stratification • Outcome Measures • Clues to Pathogenesis • Inflammation,Fibrosis Yes(?) Yes Yes Yes Colorado Clinical Proteomics Program
Hypothesis and Specific Aims • Hypothesis: Development and Validation of Protein Bio- • Markers will lead to improved care in Pediatric Lung Disease • Aim 1. Establish a Clinical Proteomics Program in Pediatric • Lung Disease comprising five cores to develop and validate • panels of Protein Biomarkers • Aim 2. Address specific issues in Pediatric Lung Disease • through panels of protein biomarkers: • Asthma – frequent exacerbations, failure to respond to Tx • CF, BPD – identification of rapid progressors • PAH – failure to respond to Tx • Aim 3. Develop Educational Program in Clinical Proteomics • Aim 4. Develop a National Resource for NHLBI investig. Colorado Clinical Proteomics Program
