Longitudinal study of intravenous versus subcutaneous immunoglobulin replacement therapy in hematological malignancy.

Aim: To present findings from a longitudinal study on infection risk, mortality, and patient perspective of intravenous immunoglobulin (IVIg) and subcutaneous immunoglobulin (SCIg) treatment for patients with hypogammaglobulinemia secondary to hematological malignancy or its treatment (abbreviated as SID).

Methods: Observational study period included final year of IVIg (13 patients) and of the first 3 years of SCIg (17 patients) with SID. Data were collected on clinical outcomes from medical records and patient perception via study specific questionnaire.

Primary immunodeficiency disease: a cost-utility analysis comparing intravenous vs subcutaneous immunoglobulin replacement therapy in Australia.

Background: Hospital-based intravenous immunoglobulin (IVIg) treatment has been the standard treatment mode for patients with primary immunodeficiency disease (PID). With the newer home-based subcutaneous immunoglobulin (SCIg) becoming approved for use in most countries, the question arises as to whether SCIg is a cost-effective treatment mode compared to IVIg in Australia.

Materials And Methods: We developed a Markov cohort simulation model with six health states: PID without infection, PID with infection treated at home or hospital, bronchiectasis without infection, bronchiectasis with infection treated at home or hospital, bronchiectasis with chronic Pseudomonas aeruginosa infection, and death, from an Australian healthcare system perspective.

Cost-utility analysis comparing hospital-based intravenous immunoglobulin with home-based subcutaneous immunoglobulin in patients with secondary immunodeficiency.

Background And Objective: Immunoglobulin replacement therapy (IRT) is often used to support patients with primary immunodeficiency disease (PID) and secondary immunodeficiency disease (SID). Home-based subcutaneous immunoglobulin (SCIg) is reported to be a cheaper and more efficient option compared to hospital-based intravenous immunoglobulin (IVIg) for PID. In contrast, there is little information on the cost-effectiveness of IRT in SID.

Subcutaneous Immunoglobulin Therapy for Hypogammaglobulinemia Secondary to Malignancy or Related Drug Therapy.

Immunoglobulin replacement therapy (IRT) has an important role in minimizing infections and improving the health-related quality of life (HRQoL) in patients with immunodeficiency, who would otherwise experience recurrent infections. These plasma-derived products are available as intravenous immunoglobulin (IVIg) or subcutaneous immunoglobulin (SCIg). The global demand for these products is growing rapidly and has placed pressure on supply.
