Overview

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.

Detailed description

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 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).

Interventions

  • Other Plasma, urine and stool collection
    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.

Primary outcome measures

  • Number of patients with chronic hepatic and/or digestive abnormalities [Time frame: Day 0]
  • Number of patients with an identified enteric virus [Time frame: Day 0]
  • Statistical association between chronic hepatic and/or digestive abnormalities and enteric virus infection [Time frame: Day 0]
Secondary outcome measures (8)
  • Description of characteristics of primary immunodeficiency of patients presenting enteric virus associated hepatitis (EVAH) [Time frame: Day 0]
  • Description of global impact of chronic viral infection [Time frame: Day 0]
  • Microbiological characterization of patients presenting enteric virus associated hepatitis (EVAH) [Time frame: Day 0]
  • Anatomic-pathologic characterization of patients presenting enteric virus associated hepatitis (EVAH) [Time frame: Day 0]
  • Descrition of immunological characterization of patients presenting enteric virus associated hepatitis (EVAH) [Time frame: Day 0]
  • Phenotypically characterize the cellular response in EVAH patients [Time frame: Day 0]
  • Transcriptionally characterize the cellular response in EVAH patients [Time frame: Day 0]
  • Specific anti-viral responses in patients presenting enteric virus associated hepatitis (EVAH) [Time frame: Day 0]
