Retrospective analysis of the data of common variable
immunodeficiency (CVID) patients
In PAD patients, serum total protein, albumin, IgG levels and gamma
fraction in protein electrophoresis which were obtained at the time of
the diagnosis, were retrospectively evaluated from their medical
records. Detailed clinical and laboratory information of forty-seven
patients from 2015 and onwards were analyzed. Four of the patients were
diagnosed with IgG subgroup deficiency, 2 with Good syndrome and the
remaining 41 with CVID. The ability of the CG and electrophoretic gamma
globulin cut-off values to predict low serum IgG levels was evaluated.
Patients who did not have simultaneous CG and IgG values at the time of
the diagnosis, were not included in the retrospective analysis.
