Minipooled-IVIG in Primary Immunodeficiency Disease
Study of Safety and Efficacy of Mini-pool Intravenous Immunoglobulin (MP-IVIG) Prepared by Assiut University Hospital Blood Bank in Primary Immunodeficiency Patients
- study the pharmacokinetics of mini-pooled intravenous immunoglobulin( MP-IVIG)
Study the safety and efficacy of a newly developed preparation of MP-IVIG in children with primary immunodeficiency (PID) :
- Adverse reaction of MP-IVIG(anaphylaxis and haemolysis)( no or mild or moderate)
- Prevention of severe bacterial infection
- Improvement of general health(weight gain and mentality)
- Integration in to social live
- Compare the efficacy of MP-IVIG to standard IVIG in children with primary immunodeficiency (PID).

Description détaillée
Primary immunodeficiency diseases (PID) are a heterogeneous group of inherited disorders of the immune system, predisposing individuals to recurrent infections, allergy, autoimmunity, and malignancies. Clinical descriptions have already been made for more than 200 PIDs, for which over 150 forms of PID have been molecularly characterized .
A population prevalence of diagnosed PID in the United States at approximately 1 in 1,200 persons.
A part from local registration in some centres there is no national registry of PID in Egypt, and hence, the prevalence of these disorders in the investigator's population is still unknown .
An increasing number of PID are recognized, and effective treatments are possible. Early use of prophylactic antibiotics and replacement immunoglobulin can prevent significant end organ damage and improve long quality of life in these patients .
Immunoglobulin G (IgG) is an essential plasma derived medicine that is lacking in developing countries .IgG shortages leave immune deficient patients without treatment, exposing them to devastating recurrent infections from local pathogens. A simple and practical method for producing IgG from normal plasma collected in developing countries is needed to provide better, faster access to IgG for patients .
Magdy EL-Ekiaby, et al 2010 introduce the concept of small-scale ("minipool") plasma processing methods implementable with minimum infrastructural requirements. They developed viral inactivation and protein purification technologies in single-use equipment to prepare virally safe solvent/detergent-filtered (S/D-F) plasma Producing a 90%pure immunoglobulin fraction in disposable single-use devices for transfusion as well as minipool S/D-F cryoprecipitate to treat bleeding disorders.

Intervention / Traitement |
|---|---|
|
Expérimental: minipooled- Intravenous immunoglobulin(MP-IVIG)
• MP-IVIG equivalent to 1 g/ kg of standard IVIG over a 6-hour to 8-hour period monthly alternated by standard IVIG for a period of 12 months follow up and the newly diagnosed cases admitted to AUH in the follow up period will be included.
|
The process of MP-IVIG preparation will involve the use of caprylic acid for purification and virus inactivation of Igs from mini-pools of 20 plasma donations collected in our CBTS in AUH.
The equipment used for the process comprised disposable blood bags, hemodialyzers, and purification and microbial filters.
