Primary Immunodeficiencies (PID) may affect both children and adults. These are inherited rare diseases of the immune system leading to an increased susceptibility to severe and/or recurrent infections (caused by a wide array of infectious agents, both regular and opportunistic) of many organs (upper and lower airways, digestive tract, skin…). They can also lead to autoimmunity, allergy, benign lymphoproliferation (enlargement of the liver, spleen, lymph nodes…) and potentailly malignancy (cancer).

CEREDIH’s missions are:

  • Enhance PID diagnosis and set a management strategy through a national network of clinicians (both pediatricians and adult physicians) and of biologists. This network is coordintaed by the CEREDIH team and a national steering commitee.
  • Set and share guidelines
  • Coordinate research and epidemiological studies
  • Contribute to education, awareness, and information for healthcare professionals, patients and family members
  • Coordinate a national network of social workers dedicated to the management of patients with PID
  • Be a partner to health agencies and policy decision makers along with the patients associations

CEREDIH is affiliated to the French Rare Diseases « Filiere » MARIH and the European Reference Network (ERN) RITA.

  • Predominantly antibody deficiencies, including agammaglobulinemia, common variable immune deficiency (CVID), Hyper-IgM syndrome
  • Combined immune deficiencies, including severe combined immune deficicies (SCID or « bubble-boy disease », Wiskott-Aldrich syndrome
  • Innate immune deficiencies, including chronic granulomatous diseases, leukocyte adhesion deficiency, immune deficiency leading to elective infectious susceptibility
  • Autoimmune and Immune dysregulation deficiencies, including autoimmune lymphoproliferative syndrome, hemophagocytic lymphohistyocytosis
  • Complement deficiencies

Timely and accurate diagnosis is key. Diagnotic delay leads to lower prognosis. Likelihood of being cured after a Hematopoietic Stem Cell Transplant (HSCT) for SCID is above 90% if performed in the first 3 months of life whereas it is only 70% if performed after 3 months old. Early onset of the best therapies dramatically increases the survival and the quality of life. Depending on the type and severity of each PID, treatment options may vary.

Below is a non exhautive list:

  • Long term prophylactic antiobiotics and/or antifungals
  • Immunoglobulins (antibodies derived from human plasma) infused intravenously (at home or hospital) or subcutaneously (at home)
  • Enzyme replacement therapy (for a rare form of SCID
  • Hematopoietic Stem Cell Transplant (HSCT) when necessary
  • Gene therapy (for a few PID as per now)
