This condition occurs in about 25% of babies with BPD, and the association grows with increasing BPD severity. Other risk factors have been described as well. Morbidity and mortality associated with prematurity and/or BPD increase significantly in the presence of PH.\n\nThus, international guidelines encourage the use of standardized screening protocols for this condition. However, several questions regarding these recommendations are left unanswered, such as a clear definition for PH in this population.\n\nThe research aim is to prospectively evaluate prevalence, risk factors and clinical course of PH in these children. The investigators aim to identify at-risk infants early on and ultimately improve survival making use of an early targeted intervention.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD'], 'maximumAge': '2 Weeks', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria: Preterm infants with\n\n* Gestational age \\<28 0/7 weeks\n* Birth weight \\<1000 grams\n\nExclusion Criteria:\n\n* Major congenital malformations\n* Structural airway or lung disease\n* Congenital heart disease\n* Lack of parental consent'}, 'identificationModule': {'nctId': 'NCT05136235', 'acronym': 'PiEP', 'briefTitle': 'Pulmonary Hypertension in Extremely Preterm Infants', 'organization': {'class': 'OTHER', 'fullName': 'Universitair Ziekenhuis Brussel'}, 'officialTitle': 'Pulmonary Hypertension in Extremely Preterm Infants - A Prospective Cohort Study', 'orgStudyIdInfo': {'id': 'PiEP study'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'OTHER', 'label': 'Extremely preterm newborns', 'description': 'All extremely preterm newborns in Flanders will be included, it is a single arm study', 'interventionNames': ['Diagnostic Test: Echocardiography', 'Diagnostic Test: NT-proBNP']}], 'interventions': [{'name': 'Echocardiography', 'type': 'DIAGNOSTIC_TEST', 'description': 'There will be screened for pulmonary hypertension by means of serial echocardiographies during the study period', 'armGroupLabels': ['Extremely preterm newborns']}, {'name': 'NT-proBNP', 'type': 'DIAGNOSTIC_TEST', 'description': 'At 36 weeks postmenstrual age there will be screened for pulmonary hypertension by means of an NT-proBNP measurement in a blood sample', 'armGroupLabels': ['Extremely preterm newborns']}]}, 'contactsLocationsModule': {'centralContacts': [{'name': 'Barbara De Bisschop, MD', 'role': 'CONTACT', 'email': 'barbara.debisschop@gmail.com', 'phone': '0032 2 477 77 21'}], 'overallOfficials': [{'name': 'Barbara De Bisschop, MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Universitair Ziekenhuis Brussel'}, {'name': 'Filip Cools, PhD', 'role': 'STUDY_CHAIR', 'affiliation': 'Universitair Ziekenhuis Brussel'}, {'name': 'Daniƫl De Wolf, PhD', 'role': 'STUDY_CHAIR', 'affiliation': 'Universitair Ziekenhuis Brussel'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Universitair Ziekenhuis Brussel', 'class': 'OTHER'}, 'collaborators': [{'name': 'AZ Sint-Jan AV', 'class': 'OTHER'}, {'name': 'Universitaire Ziekenhuizen KU Leuven', 'class': 'OTHER'}, {'name': 'GZA Ziekenhuizen Campus Sint-Augustinus', 'class': 'OTHER'}, {'name': 'Ziekenhuis Netwerk Antwerpen (ZNA)', 'class': 'OTHER'}, {'name': 'Ziekenhuis Oost-Limburg', 'class': 'OTHER'}, {'name': 'University Hospital, Ghent', 'class': 'OTHER'}], 'responsibleParty': {'type': 'SPONSOR'}}}}
