Cell Mediated Immunity With Risk of Cytomegalovirus (CMV) in Solid Organ Transplant Recipients
United States113 participantsStarted 2010-04
Plain-language summary
Cytomegalovirus (CMV) is a common infection with 60-90% of all adults worldwide having evidence of having the infection at sometime in their life. Patients who have undergone transplantation are at risk at developing CMV, especially those patients who do not have antibodies to CMV pre-transplant, but received an organ from a recipient who has antibodies to CMV. Usually the disease CMV causes is mild and sometimes patients are not even aware they have the infection without tests to detect the virus. CMV can less commonly cause serious infections that affect many parts of the body including the intestines, liver, or lungs. In rare cases CMV infection in transplant patients can cause death.
All patients who receive a transplant are monitored for CMV infection. The purpose of this study is to determine if there is a way the investigators can determine in advance which patients are at greatest risk of CMV infection. Specifically, this study will analyze the immune system of transplant patients to determine if there are specific elements of the immune system that 1) helps protect the body against CMV infection, and 2) helps the body combat CMV once it is infected. Identifying these specific elements of the immune system could improve the physician's ability to monitor the SOT patients for CMV infection, and to help treat CMV in those patients that become infected.

Inclusion Criteria:
* Main Study Subjects will be recruited if they are listed for a SOT (liver, liver-kidney, kidney, kidney-pancreas, cardiac). At the time of transplant, consented patients will have an immediate pre-transplant blood draw for baseline labs subsequent labs will only be drawn if the donor/recipient CMV serostatus is CMV D+/R- (up to a maximum of 50 subjects) or D+/R+ or D-/R+ (up to a maximum of 50 subjects). Subjects must be ≥ 18 years of age, be consentable, and agree to have laboratory and clinical follow-up at Northwestern.
* CMV Replication Substudy
* Subjects will be recruited if they have undergone SOT, are found to have a positive CMV QnPCR (\> 600 copies/mL) and will be subsequently treated for CMV infection with either intravenous ganciclovir or oral valganciclovir therapy at the discretion of the treating provider. Subjects must be ≥ 18 years of age, able to give consent, and agree to have laboratory and clinical follow-up at Northwestern.
Exclusion Criteria:
* Subjects will be excluded if they have had a previous history of CMV infection after SOT prior to enrollment (a prior episode of CMV infection or replication prior to the onset of the current episode). Subjects will also be excluded if the subject cannot give informed consent or if the subject is not able to comply with follow-up testing and/or treatment.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
