Study on Infectious Mononucleosis in Munich (IMMUC)

February 5, 2024 updated by: Technical University of Munich

Study on Biomarkers and Causative Factors of Complicated and/or Protracted Epstein-Barr Virus-associated Infectious Mononucleosis

This observational clinical study aims at the identification of novel biomarkers and causative factors of complicated and/or protracted Epstein-Barr virus-associated infectious mononucleosis (IM).

Clinical, biochemical, and routine virological data were collected from 200 patients with IM, novel analytical tools were implemented, and immunological and virological experimental data were generated using blood samples and mouthwashes. Patients have been investigated within four weeks after the onset of symptoms as well as one month and six months thereafter.

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

EBV-associated diseases are a severe and global health problem, and novel tools and targets for a better pathogenetic understanding, diagnosis, treatment, and prevention are clearly needed. Here we propose to use several novel experimental approaches to investigate immunological, virological, biochemical, and clinical features in an observational study on Munich IM patients.

This study aims at identifying biomarkers and causative factors of protracted and/or complicated IM to facilitate the development of novel approaches to early diagnosis, therapy, and prevention of severe, life-threatening, and chronic EBV-associated diseases, including post-viral syndromes.

Two hundred patients with IM onset within the last four weeks were recruited from Munich health care institutions and were re-investigated at one and six months after the onset of symptoms. A novel diagnostic scoring system was developed to indicate the severity, complexity, and protraction of symptoms.

Investigated clinical parameters, including reported symptoms and physical signs of IM, as well as candidate risk factors in the medical history of patients and family members. Peripheral blood was analysed by established and novel analytical assays to determine the immunological and virological phenotypes of IM, and viral load was determined in mouthwashes.

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

  • Child
  • Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

200 patients with infectious mononucleosis.

Description

Inclusion Criteria:

  • IM onset within the last four weeks
  • with at least one of four typical clinical findings (tonsillopharyngitis, fever, lymphadenopathy, fatigue) - virological findings indicating primary EBV infection (EBV-specific antibodies, EBV DNA).

Exclusion Criteria:

  • Pregnancy
  • transfusion
  • and/or transplantation during the last year
  • and/or no informed consent.

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
Severity
Time Frame: Six months
Maximal severity of symptoms during the course of IM according the the IMMUC-Score.
Six months
Complexity
Time Frame: Six months
Maximal complexity of symptoms during the course of IM according the the IMMUC-Score
Six months
Protraction
Time Frame: Six months
Maximal protraction of symptoms during the course of IM according the the IMMUC-Score.
Six months

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.
Outcome Measure
Measure Description
Time Frame
Immune status
Time Frame: Within four weeks post symptom onset and at one and six months thereafter.
Cellular and humoral immune status, EBV viral load, antibodies against EBV proteome.
Within four weeks post symptom onset and at one and six months thereafter.

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.
March 1, 2016

Primary Completion (Actual)

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.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
