Abstract

Mycophenolate mofetil (MMF) is an immunosuppressive drug used for the treatment of autoimmune rheumatological diseases. To test the risk of hypothetical drug-induced hypogammaglobulinemia, the aim of this study was to report the trend of the immunoglobulin (Ig) values and of the infectious diseases in children treated with MMF. This study retrospectively evaluated demographic, clinical, and laboratory data of a cohort of patients affected by a chronic rheumatic disease receiving MMF, followed at the Rheumatology Unit of Meyer Children Hospital, Florence. A total of 29 pediatric patients were enrolled. In patients with normal values of immunoglobulins at the baseline, treatment with MMF resulted in a statistically significant reduction of the IgG levels (p = 0.0058) and in a decrease of IgM levels not reaching statistical significance. The levels of IgA were not affected. During the follow-up, seven patients developed an humoral immune defect. The univariate analysis did not identify any risk factors related to the iatrogenic hypogammaglobulinemia. The infection rate during MMF therapy was significantly higher than the 12-month period before therapy (p = 0.006), while the severe infections did not significantly increase (p = 0.1818), even considering only the patients with hypogammaglobulinemia.
