Cell Mediated Immunity With Risk of Cytomegalovirus (CMV) in Solid Organ Transplant Recipients

Completed

Conditions studied: Awaiting Organ Transplant, Infection in Solid Organ Transplant Recipients

In brief

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.

Who can join

You may qualify if…

• 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.

You may not qualify if…

• 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.
