Summary

This is an observational, retro-prospective, moncentric study focused on Inborn Errors of Immunity, an heterogeneous group of inherited diseases due to defects in the differentiation and/or function of the immune system. The primary aim of this study is to obtain a clinical-immunological, functional and molecular characterisation of paediatric and adult patients with confirmed or suspected Inborn Errors of Immunity, particularly of patients with manifestations of immunedysregulation, focusing on clinical course, immunophenotypic laboratory and functional abnormalities, genetic background.

Detailed description

Due to the observational nature of the study, patients were and will be treated according to normal clinical practice and in accordance with medical judgement. The following evaluations were performed in the retrospective cohort and will be performed in the prospective cohort: * Standard haematochemical examinations; * Extended lymphocyte typing; * Plasma dosage of immunoglobulins; * Evaluation of early and late responses to Measles-Parotitis-Rosolia and Diphtheria-Tetanus-Pertussis vaccinations; * Evaluation of antibody responses to vaccines against Haemophilus Influenzae, Neisseria Meningitidis and Pneumococcus; * Detection of auto-antibodies on HEp-2 cells, and of auto-antibodies directed against haemopoietic cells and proteins of innate and adaptive immunity; * Plasma dosage of complement factors (C3, C4); * Radiological assessment; * Functional immunological assay; * Molecular-genetic investigations of targeted gene panels involved in immunodysregulation and Inborn Errors of Immunity.
