Znaczenie pierwotnych niedoborów odporności ze szczególnym uwzględnieniem zmiennego pospolitego niedoboru odporności w rozwoju nowotworów limfoidalnych

Primary immunodeficiencies are associated with an increased risk of malignancy. One of the most common immune deficiencies in adults is common variable immunodeficiency — CVID. These patients relatively often develop lymphoproliferative tumours compared to a healthy population. There are cases of the development of this type of cancer in children and young people with CVID without previous symptoms of lymphoid hyperplasia, and even before the diagnosis of immunodeficiency. Therefore, it is important to recognise early symptoms of the disease and imple­ment prompt treatment. The aim of this study was to analyse the mechanisms that may contribute to the development of lymphoid neoplasms in people with CVID. Understanding the immunopatho­genesis of this disease may help to identify future targets for immunotherapy.
