Mini-pool Intravenous Immunoglobulin (MP-IVIG) in Guillain-Barré Syndrome
Efficacy of Mini-pool Intravenous Immunoglobulin (MP-IVIG) Prepared by Assiut University Hospital Blood Bank in Guillain-Barré Syndrome
- study the pharmacokinetics of mini-pooled intravenous immunoglobulin( MP-IVIG)
to determine the efficacy of intravenous immunoglobulin (IVIg) in hastening recovery and reducing the complications of Guillain-Barré syndrome (GBS).
- The MP-IVIG was tolerated and presented no safety issues in a previous study and we will be confirmed by monitoring any adverse events (anaphylaxis and haemolysis) ( no or mild or moderate) and reporting them to ethical committee safety monitoring group.
Efficacy will be confirmed by:
- Patient able to walk
- Improvement of general health.
- Integration in to social live
- to compare the efficacy of IVIg to plasma exchange (PE) in hastening recovery and improving the condition of GBS

Detailed Description
Guillain-Barré syndrome (GBS) is a frequent cause of neuromuscular paralysis occurring at all ages. The incidence of GBS is reported to be 1.2-2.3 per 100,000 per year .
GBS is a post infectious disorder. The most frequently identified preceding infection is Campylobacter jejuni. Others are cytomegalovirus, Epstein-Barr virus, Mycoplasma pneumoniae, and Haemophilus influenzae . Many reports have documented the occurrence of GBS shortly after vaccinations, operations, or stressful events, but the causality and pathophysiology are still debated .
Rapidly progressive weakness is the core clinical feature of GBS. By definition, maximal weakness is reached within 4 weeks, but most patients reach it within 2 to 3 weeks. Thereafter, patients enter a plateau phase that ranges from days to several weeks or months . This phase is followed by a usually much slower and variable recovery phase. In Europe, about one-third of GBS patients remain able to walk ("mild patients") .about 25% of the GBS patients who are unable to walk ("severe patients") need artificial ventilation. This is predominantly due to weakness of the respiratory muscles. GBS has a great impact on social life and the ability to perform activities of daily life. therefore, GBS remains a severe disease for which better treatments are required .
. Magdy EL-Ekiaby, et al 2010 introduce the concept of small-scale ("minipool") plasma processing methods. The preparation of the Immunoglobulin G (IgG) plasma fractionation from 20 blood donations which are tested for anti-A and anti-B titre < 32. 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 .
IVIG adverse events (AEs) are not frequent; hemolysis after IVIG is a known, rare complication. Higher doses and non-O blood group are key risk factors. The incidence of post-IVIG hemolysis is estimated at 1 per 1000 IVIG treatment episodes, most of which occur within 2 days of exposure. Although the preparation of blood group specific IVIGs in industry is a complex issue because of the pooling of thousands of plasma donations per batch, the preparation of blood group-specific mini-pool IVIG (MP-IVIG) is possible because each pool consists of only 20 plasma donations. Blood group-matched MP-IVIG is assumed to reduce the incidence of IVIG-associated hemolysis, which is largely caused by the presence of anti-A and anti-B agglutinins reacting with non-O blood group recipients.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
EXPERIMENTAL: Mini-pool Intravenous Immunoglobulin (MP-IVIG)
will receive blood group -specific MP-IVIG in a regimen of 2 g/kg bodyweight, usually as 0.4 g/kg bodyweight per day for five consecutive days within two weak of onset of symptoms.
|
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.
|
EXPERIMENTAL: plasmapheresis
plasma exchange (plasmapheresis ) in a regimen of removing of 1.3 plasma volumes in each cycle for total of five cycle for five consecutive days within four weeks of onset of symptoms.
