Cytomegalovirus-Specific Response Measured by QuantiFeron® and Overall Immunologic Response Measured by ImmuKnow® in Lung Transplant Patients CMV-positive

The purpose of this study is to determine the sensitivity and specificity of QuantiFeron® and ImmuKnow® in combination for early detection of patients who will develop CMV infection in lung transplant patients with CMV-positive serology (R+) prior to transplant.

About this study

The secondary objectives of the study are:

  • To evaluate Cytomegalovirus (CMV)-specific immune response measured by QuantiFeron®.
  • To evaluate overall immune response measured by ImmuKnow®.
  • To study the course of QuantiFeron® and ImmuKnow®over the follow-up period.
  • To correlate levels of ImmuKnow® and QuantiFeron®.
  • To evaluate the relationship between levels and doses of immunosuppressants and their relationship to degree of overall immunosuppression (ImmuKnow®).
  • To evaluate the relationship between infections, immunological complications and degree of overall immunosuppression (ImmuKnow®).

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Patients aged ≥ 18 years.
  • Men or women who have received a lung transplant.
  • CMV-seropositive patients (R+).
  • Patients who have been informed of the study procedures and have signed the informed consent form.
  • Over 3 months posttransplant.

Exclusion criteria

  • Patients who are not expected to be able to be followed during the first 12 months posttransplant.
  • Patient participation in another clinical trial or study will not be a criterion for exclusion.

Treatment and study plan

Primary outcomes

  1. Quantification of interferon-γ produced by specific CD8+ (cluster of differentiation 8) T cells after ex-vivo stimulation with various CMV epitopes using the commercial assay QuantiFeron®- CMV

    Time frame: up to 12 months from transplant

    Quantiferon® is assessed multiple times and it will be considered positive when first positive test is assessed.

  2. Measurement of overall immune response by determination of the activity of CD4+ (cluster of differentiation 4) T cells

    Time frame: up to 12 months from transplant

    InmunKnow® is assessed multiple times and it will be considered positive when first positive test is assessed.

  3. Quantification of CMV viral replication in blood measured by PCR (polymerase chain reaction)

    Time frame: up to 12 months from transplant

    PCR is assessed multiple times and it will be considered positive when first positive test is assessed.

Secondary outcomes

  1. Measurement of immunosuppressive drugs: Blood levels of calcineurin inhibitors (tacrolimus or cyclosporine). Mycophenolate (or equivalent) dose and corticosteroid doses.

    Time frame: up to 12 months from transplant

  2. Complete blood count (WBC count) and routine biochemistry

    Time frame: up to 12 months from transplant

  3. Determination of glomerular filtration rate

    Time frame: up to 12 months from transplant

  4. Course of graft function by measuring GFR (glomerular filtration rate)

    Time frame: up to 12 months from transplant

  5. Complications since last visit: Infections, rejection episodes, chronic graft dysfunction, other complications

    Time frame: up to 12 months from transplant

  6. CMV prophylaxis, drug and dosage. Serious Adverse events related or no related to the drug

    Time frame: up to 12 months from transplant

  7. Follow-up loss/death (if it occurs)

    Time frame: up to 12 months from transplant
