Abstract
La inmunodeficiencia variable común (IDVC) es la inmunodeficiencia primaria (IDP) sintomática más frecuente, caracterizada por una elevada susceptibilidad a infecciones bacterianas recurrentes, así como un amplio perfil de expresión clínica con manifestaciones autoinmunes, inflamatorias y predisposición a malignidad. Su variabilidad clínica sugiere un defecto inmunoregulatorio complejo, con alteraciones tanto en la inmunidad innata como en la adaptativa. La caracterización genética ha cobrado especial interés relevante con implicación pronóstica y terapéutica. El primer y más importante escalón terapéutico es el reemplazo con inmunoglobulinas (IgRT), que si se inicia precozmente puede disminuir drásticamente el número y la gravedad de las infecciones. El pronóstico de los pacientes con IDVC está condicionado principalmente por la existencia de complicaciones infecciosas, así como por el desarrollo de malignidad...
Common variable immunodeficiency (CVID) is the most frequent symptomatic primary immunodeficiency (PID), characterized by susceptibility to recurrent bacterial infections, as well as a broad clinical profile with autoimmune, inflammatory manifestations and predisposition to malignancy. The clinical variability of CVID suggests a complex immunoregulatory defect, with alterations in both innate and adaptive immunity. Genetic and molecular characterization has gained relevant interest nowadays. The immunoglobulin replacement (IgRT) is the most important therapeutic approach with prognostic implication in CVID. The main objective of this study was to establish new CVID diagnostic and prognostic biomarkers, as well as to determine and validate a scale based on the combination of independent biomarkers with potential prognostic role in CVID. In conjunction with this project, we intend to deepen our understanding of the biological and pathophysiological mechanisms involved in CVID. The results corresponding to the objectives established in this thesis are compiled in three original articles, which are attached to this work...
