Real-world CMV Outcomes Among Kidney Transplant Recipients in Brazil

February 20, 2024 updated by: Helio Tedesco Silva Junior, Hospital do Rim e Hipertensão

Single-center, Non-interventional, Retrospective Study on the Outcomes of Infection by CMV, Treatment Patterns, and Healthcare Resource Utilization Among CMV Recipients Kidney Transplant in Brazil

This is a single-center, non-interventional, retrospective study of data, at the level of the individual without identification, extracted from medical records of adult patients undergoing a kidney transplant procedure after 1st from January 2018 until reaching the sample size enrollment (around 500 individuals); this refers to the period of verification of individuals' eligibility for entry into the study. Individuals under strategy preemptive patients who developed CMV infection/disease within 12 months after transplantation. The data will be collected from date of transplant (including pre-transplant clinical history) until completion of at least 12 months after transplantation, or until graft loss, or recipient death or loss to follow-up, when/if applicable.

Detailed Description

Data will be collected from medical records and will include transplant recipient characteristics, transplant-related information, CMV status, clinical outcomes, treatment patterns, healthcare resource utilization and captured on an electronic Intake Form.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Probability Sample

Study Population

The study population will be entirely adult kidney transplant recipients (age ≥18 years at the time of time of transplantation) who developed a first episode of CMV infection/disease in the first year of transplant. Eligible individuals will be enrolled consecutively based on transplant date, starting from the first year as defined in the inclusion/exclusion criteria.

Description

Inclusion Criteria:

  • Received a single kidney transplant after January 1, 2018
  • Age over 18 years at time of kidney transplant.
  • It was under preemptive strategy.
  • Diagnosed with CMV infection/disease within the first 12 months after kidney transplant.
  • Follow-up information is available in medical records for at least 12 months after confirmation of CMV infection, or even loss of the allograft, death of the recipient or loss of follow-up of the receiver, when/if applicable.

Exclusion Criteria:

  • Diagnosed as a carrier of the human immunodeficiency virus (HIV+), hepatitis B virus and/or hepatitis C before kidney transplantation.
  • Participation in any interventional study during the period between kidney transplantation and a period of 12 months after CMV diagnosis.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Incidence of infection, CMV disease, and tissue invasive disease.
Time Frame: 12 months
Incidence of infection, CMV disease, and tissue invasive disease.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
October 1, 2023

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
