About this study

Official title: INFLUENZA VIRUS INFECTIONS IN TRANSPLANT RECIPIENTS: A MULTICENTER REGISTRY

The investigators purpose is to prospectively characterize influenza infections over a 3 year period in transplant patients using a registry system. The investigators plan to generate robust data on clinical features of upper and lower respiratory disease, antiviral therapy and its effects on disease outcome, as well as quantitative virologic data on shedding and antiviral resistance. The investigators also will study the long term sequelae of influenza infections and look at development of rejection.

Read the detailed description

This study will be a prospective, multi-center study conducted at investigator sites who comprise the Influenza in Transplant collaborative study group. This includes over 30 centers from across North America and Europe. The co-ordinating center will be the University of Alberta. We will aim to enrol 300 patients in the registry over a 3 year period.

The following information will be gathered:

  1. Clinical Information
  • Baseline demographic information about the transplant (including immunosuppression, graft function)
  • Comorbidities such as diabetes, obesity, chronic lung disease
  • Symptoms of infection, radiologic features of infections
  • Antiviral use
  • History of vaccination
  • Outcomes such as hospitalization, ICU admission, mechanical ventilation, death
  • Long term outcomes: allograft function, chronic respiratory disease
  • Laboratory parameters including lymphocyte count, immunoglobulin levels, renal function
  • Adverse events - all serious adverse events occurring during the study (till day 180) will be reported. These include: a) hospitalization; b) congenital deformity; c) death; d) disability; and e) other adverse events the investigator considers serious. Pregnancy during the follow-up period will also be reported.
  1. Virology
  • Method of diagnosis (DFA, viral culture, PCR)
  • Subtype of influenza virus (ie HxNx)
  • Viral Shedding by serial NP swabs at day 0 (diagnosis), 3, 6, 11, 18, 28 (weekly thereafter if shedding persists)
  • Quantitative PCR of NP swabs (centrally at University of Alberta)
  • Antiviral resistance testing at first and last positive swabs
  1. Immunology - Serum collection at disease onset and 4-6 weeks afterwards for
  • Serology against circulating influenza viruses
  • Production of HLA alloantibodies

Significance:

Despite the recognized importance of influenza in transplant patients, there is actually very limited prospective data. This registry will represent the largest prospective data collection on influenza in transplant patients and will provide invaluable data on the clinical presentations, antiviral efficacy and other parameters related to influenza.

Questions about this trial

What is this clinical trial studying?

An observational study of Influenza Infection in Transplant Patients, run by University of Alberta at 2 sites in Canada.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 1 Jun 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01256255, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Jun 2022.
