Managing hypogammaglobulinaemia secondary to haematological malignancies in Australia and New Zealand: a clinician survey.

In comparison to limited international data, this survey finds variation in practice, which may be due to differences in local policies governing access to Ig. These findings highlight the need for research into the indications for Ig commencement and cessation, and will inform design of prospective trials of infection prevention in secondary hypogammaglobulinaemia.
