Abstract
Background
Hypogammaglobulinemia is a major adverse effect from rituximab. However, the association between rituximab-induced hypogammaglobulinemia and infection frequency is unknown.
Methods
Patients who received rituximab for complicated nephrotic syndrome between February 2006 and October 2020 were enrolled in this retrospective observational study. Infections requiring antibacterial or antiviral agents or hospitalization were identified, and the characteristics of infections were compared according to infection type.
Results
One hundred and forty patients were enrolled. Fifty infection events were detected in 36 patients, 45 infection events in 32 patients required hospitalization, and 1 severe infection event required intensive care unit admission. In eight patients who developed severe hypogammaglobulinemia (serum IgG level < 200 mg/dL) for more than 1 year after rituximab treatment, eight infections occurred in six patients; six of these infections did not occur during the period of severe hypogammaglobulinemia. Febrile neutropenia accounted for 54.2% (13/24) of all infections among the patients with hypogammaglobulinemia. The incidence of infections was 0.028 (95% confidence interval = 0.017–0.448), 0.071 (95% [CI] = 0.041–0.114), and 0.096 (95% [CI] = 0.019–0.282) patient-years in patients with normal serum IgG levels and those with mild and severe hypogammaglobulinemia, respectively. Immunoglobulin replacement therapy was not administered to any patients except for the treatment of infection.
Conclusions
Our results showed no statistically significant association between hypogammaglobulinemia severity and infection rate. In addition, the frequency of infection was relatively low even in patients with severe hypogammaglobulinemia, suggesting that immunoglobulin replacement therapy may not be necessary for rituximab-treated patients with severe hypogammaglobulinemia.
