Brief summary

The management of patients with primary immune deficiency is increasingly codified, however contraception and pregnancy have not yet extensively studied or codified, and the medical monitoring and the prevention of infectious complications thus remains at the discretion of the practitioner. The aim the research is to study the obstetric features and outcome of patients with primary immune defects.

Detailed description

Primary immune deficiencies constitute a large group of immune system disorders of genetic origin which can associate, to varying degrees, an increased susceptibility to infections and immunopathological manifestations: allergy, inflammation, autoimmunity, lymphoproliferation, tumors malignant. Although their prevalence remains underestimated, there has been an increase in the number of cases diagnosed in the past 10 years. The national average prevalence is 8.6 patients per 100,000 inhabitants and the diagnostic incidence is 400 new cases per year in France. Major improvement in the management of primary immunodeficiencies have drastically changed patients outcome. Most patients now reach adulthood and the possibility of carrying out a pregnancy project, that has already reported for patients suffering from hypogammaglobulinemia or variable common immune deficiency, is now increasingly reported for other types of inherited immunodeficiencies. Whereas the management of patients with hereditary immunodeficiencies is increasingly codified, contraception and pregnancy have not yet been the subject of recommendations: medical monitoring and the prevention of infectious complications thus remain at the discretion of the practitioner. The aim the research is to study the obstetric experiences of patients with a primary immune deficiency, paying particular attention to infectious complications.
