The use of octagam and gammanorm in immunodeficiency associated with hematological malignancies: a prospective study from 21 French hematology departments.

Immunoglobulin replacement therapy (IgRT) is increasingly used in secondary immunodeficiency (SID) related to hematological malignancies (HM) to prevent infections. Study's objective was to document prospectively the efficacy and safety of IgRT in patients with HM-associated SID. Non-interventional, prospective French longitudinal study. One-hundred and sixty patients starting IgRT for HM-associated SID (myeloma: 54 cases, chronic lymphoid leukemia: 54, aggressive non-Hodgkin B-cell lymphoma: 19, indolent non-Hodgkin B-cell lymphoma: 29, and Hodgkin disease: 4. entered an observational, prospective, longitudinal study and were followed-up for 8.7 ± 4.0 months. Seventeen patients died (five within the context of sepsis). Compared to baseline, IgRT increased serum immunoglobulin levels by 3.4 ± 2.4 g/L and decreased frequency and severity of infections. Treatment was discontinued in 9% of patients, stopped for futility in 31%, temporally interrupted in 8%, suspended during summertime in 14% and pursued without interruption in 38% of patients. Our data confirm the efficacy of IgRT in reducing the risk of infections in HM-associated SID therefore fulfilling physicians' main expectations. They also illustrate the heterogeneity of management policies within the community setting.
