About this study

Dysimmune and specially hepatic immuno-pathological processes are frequent in patients with PIDs (primary immune deficiencies), particularly but not exclusively in patients with humoral defects. In the latter, nodular regenerative hyperplasia is a frequent complication. It is often associated with mislabeled chronic enteropathy. The investigators hypothesized that chronic viral infection with an enteric virus and the immune response that it implies might explain these processes.

To identify populations at risk of EVAH (enteric virus-associated hepatitis), four cohorts of patients will be studied:

  • Primary humoral immune deficiencies
  • Secondary humoral immune deficiencies (following anti-CD20 monoclonal antibodies, CAR-T cells)
  • Combined immunodeficiencies
  • Severe combined immunodeficiency syndrome (SCID) after allograft with humoral defect The investigators will collect clinical, biological and genetic information and features related to immunological responses and inflammatory damage for these patients. The investigators will include EVAH suspected patients and control patients in each cohort.

The investigators will take additional blood, stool and urine samples during the same time as the samples taken for the care.

The investigators will carry out tests for enteric viruses screening on stool, urine and plasma. The investigators will perform the viral screening on organ biopsies taken as part of the care.

A subgroup of representative patients (EVAH+ and EVAH-) will benefit from ancillary studies to characterize the leukocyte populations in the circulating blood and the immune response for these processes. In EVAH patients, the investigators will study specific anti-viral cellular response.

The investigators will take additional blood, stool and urine samples during the same time as the samples taken for the care.

The investigators will carry out tests for enteric viruses screening on stool, urine and plasma by multiplex RT-PCR (Norovirus GI, Norovirus GII, Rotavirus, Sapovirus, and Astrovirus) and by targeted PCR (Enterovirus, Adenovirus, Aichi virus, Parechovirus, Kobuvirus and Astrovirus MLB1) on plasma and urine. The investigators will perform the viral screening on organ biopsies (liver, kidney, digestive tract, spleen, lymph node) taken as part of the care by mNGS (Metagenomics Next Generation Sequencing).

A subgroup of representative patients (EVAH+ and EVAH-) will benefit from ancillary studies to characterize the leukocyte populations in the circulating blood and the immune response for these processes. In EVAH patients, the investigators will study specific anti-viral cellular response by specific pentamers and elispot (enzyme-linked immunospot).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Plasma, urine and stool collectionOther

    During a consultation for follow-up, we will take an extra-volume during a blood sample taken as part of the care. We will also collect stool and urine.

    There will be no biological collection for these samples. Organ biopsies carried out as part of the care (liver, kidney, digestive tract, spleen, lymph node) will also be studied as part of this research.

Questions about this trial

What is this clinical trial studying?

An observational study of Humoral Primary Immunodeficiencies (PIDs) and Secondary Form of Humoral Immunodeficiencies, run by Assistance Publique - Hôpitaux de Paris at 3 sites in France.

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 7 inclusion and 2 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: finished, as of the sponsor's last update on 24 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in France. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of patients with chronic hepatic and/or digestive abnormalities (time frame: Day 0). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06659588, which also lists 4 linked publications.

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 24 Sep 2026.
