About this study

Official title: Observational Study on the Application of Flow Cytometry for the Study of T-Cell Populations in Lymphoma-associated Hemophagocytic Lymphohistiocytosis

The goal of this study is to explore the associations between T cell activation and the occurrence of hemophagocytic lymphohistiocytosis (HLH) in patients with newly diagnosed lymphomas. The specific aims are:

Prediction of Lymphoma-Associated HLH (LA-HLH): Compare flow cytometric T cell activation markers with the H-score to predict LA-HLH.

Read more

Identification of new markers for predicting HLH in patients with aggressive lymphoma.

Description of the incidence rate of LA-HLH. Assessment of the outcomes of LA-HLH identified by flow cytometric analysis or the H-score.

This prospective, single-center observational study will include 150 patients newly diagnosed with aggressive lymphoma within one year. Peripheral blood samples will be taken at diagnosis alongside routine blood chemistry tests for flow cytometric analysis of the T-lymphocyte activation profile. Data on disease characteristics will be collected to calculate the H-score, HLH-2004 score, and OHI score for diagnosing HLH. The flow cytometry results will be compared with these scores to evaluate their effectiveness in diagnosing LA-HLH.

Read the detailed description

Hemophagocytic lymphohistiocytosis (HLH) is a rare and severe syndrome characterized by excessive immune system activation and dysregulation. This leads to an overproduction of cytokines and activation of the histiocytic-macrophage system, potentially resulting in multi-organ failure and death. HLH can be classified into primary and secondary forms. Secondary HLH is often triggered by infections, autoimmune diseases, or neoplasms, with lymphomas being the most frequent neoplastic triggers.

There is limited knowledge about secondary HLH, particularly regarding early diagnosis and optimal management. This project aims to address this gap by analyzing cytotoxic T-cells and cell expression markers using flow cytometry, building on findings from two pediatric studies.

Aggressive onset lymphomas may induce a systemic hyperinflammatory state, complicating the diagnosis of HLH, especially in the presence of concurrent bacterial or viral infections. Given the rarity of HLH and its poor prognosis if not promptly diagnosed, further research is crucial, especially in lymphoma-associated cases.

This study aims to apply T-cell activation profiling, previously demonstrated in pediatric populations, to patients with aggressive Non-Hodgkin's Lymphoma and Hodgkin's Lymphoma to identify HLH-associated cases at onset.

The study aims to include 150 patients diagnosed with aggressive lymphoma within a one-year period A peripheral blood sample, collected alongside routine blood chemistry tests at diagnosis, will be used for the flow cytometric study of the T-lymphocyte activation profile. Data pertaining to disease characteristics will be gathered to calculate diagnostic scores for HLH, including the H-score, HLH-2004 score, and OHI score. The flow cytometry results will then be compared with these score parameters to assess their correlation with the diagnosis of lymphoma-associated HLH (LA-HLH).

Questions about this trial

What is this clinical trial studying?

An observational study of Lymphoma and Hemophagocytic Lymphohistiocytoses, run by Fondazione Policlinico Universitario Agostino Gemelli IRCCS at 1 site in Italy.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 5 Sep 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Stefan Hohaus, MD (063015 ext. 4180, stefan.hohaus@unicatt.it), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Assocation of flow cytometry parameters on peripheral blood with the H-score, the standard for the diagnosis of lymphoma-associated HLH (time frame: 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Sep 2024.
