Surveillance Study of Viral Infections Following Lung Transplantation
The present study was conducted to study the impact community acquired respiratory virus (CARV) infections in an outpatient setting on graft function of lung transplant recipients. The study was aimed to identify risk factors for CARV infections.
The study was further intended to investigate an association of Epstein-Barr virus (EBV), cytomegalovirus (CMV) and human adenovirus (HAdV) with the development of BOS and to identify risk factors for virus detection in blood.
Epstein-Barr Virus Infections
|Study Design:||Observational Model: Cohort
Time Perspective: Prospective
|Official Title:||Season Surveillance Study of Viral Infections in Lung Transplant Recipients|
- Incidence of bronchiolitis obliterans syndrome [ Time Frame: 1 year ] [ Designated as safety issue: No ]
- Incidence of acute rejection [ Time Frame: 1 year ] [ Designated as safety issue: No ]
- Incidence of hospitalisation [ Time Frame: 1 year ] [ Designated as safety issue: No ]
- Incidence of graft loss (death or re-do-transplantation) [ Time Frame: 2 year ] [ Designated as safety issue: No ]
Biospecimen Retention: Samples Without DNA
Nasopharyngeal and oropharyngeal swabs
|Study Start Date:||October 2005|
|Study Completion Date:||December 2007|
|Primary Completion Date:||December 2007 (Final data collection date for primary outcome measure)|
Informed consent was obtained from the LTx recipients and the study was approved of by the institutional review board of Hannover medical school.
LTx recipients are screened for CARV infections during the cold season (end October until end April) in a single-centre outpatient clinic. Symptoms of upper (URTI) and lower respiratory tract infections (URTI) are recorded by questionnaires and findings.
Nasopharyngeal and oropharyngeal swabs (NOS) were performed to detect RV-antigens by immunofluorescence testing (IFT) of respiratory-syncytial virus (RSV), adenovirus, parainfluenza (PIV), influenza and cultures for CARV are performed. BAL was performed when clinically indicated and processed by IFT. Multiplex-PCR to detect 14 CARV are processed in symptomatic patients.
In addition blood samples are monitored at each contact to investigate an association of Epstein-Barr virus (EBV), cytomegalovirus (CMV) and human adenovirus (HAdV) with the development of BOS and to identify risk factors for virus detection in blood.
