Baygam (Immune Globulin Human) - Summary



Immune Globulin (Human) -- BayGam® treated with solvent/detergent is a sterile solution of immune globulin for intramuscular administration; it contains no preservative. BayGam is prepared by cold ethanol fractionation from human plasma. The immune globulin is isolated from solubilized Cohn fraction II. The fraction II solution is adjusted to a final concentration of 0.3% tri-n-butyl phosphate (TNBP) and 0.2% sodium cholate. After the addition of solvent (TNBP) and detergent (sodium cholate), the solution is heated to 30°C and maintained at that temperature for not less than 6 hours. After the viral inactivation step, the reactants are removed by precipitation, filtration and finally ultrafiltration and diafiltration. BayGam is formulated as a 15-18% protein solution at a pH of 6.4-7.2 in 0.21-0.32 M glycine. BayGam is then incubated in the final container for 21-28 days at 20-27°C.

The prophylactic value of BayGam is greatest when given before or soon after exposure to hepatitis A. BayGam is not indicated in persons with clinical manifestations of hepatitis A or in those exposed more than 2 weeks previously.

BayGam should be given to prevent or modify measles in a susceptible person exposed fewer than 6 days previously.7 A susceptible person is one who has not been vaccinated and has not had measles previously. BayGam may be especially indicated for susceptible household contacts of measles patients, particularly contacts under 1 year of age, for whom the risk of complications is highest.7 BayGam and measles vaccine should not be given at the same time. 7 If a child is older than 12 months and has received BayGam, he should be given measles vaccine about 3 months later when the measles antibody titer will have disappeared.

If a susceptible child exposed to measles is immunocompromised, BayGam should be given immediately.8 Children who are immunocompromised should not receive measles vaccine or any other live viral vaccine.

Passive immunization against varicella in immunosuppressed patients is best accomplished by use of Varicella-Zoster Immune Globulin (Human) [VZIG]. If VZIG is unavailable, BayGam, promptly given, may also modify varicella.5

The routine use of BayGam for prophylaxis of rubella in early pregnancy is of dubious value and cannot be justified.6 Some studies suggest that the use of BayGam in exposed, susceptible women can lessen the likelihood of infection and fetal damage; therefore, BayGam may benefit those women who will not consider a therapeutic abortion.4

In patients with immunoglobulin deficiencies, BayGam may prevent serious infection. However, BayGam may not prevent chronic infections of the external secretory tissues such as the respiratory and gastrointestinal tract.

Prophylactic therapy, especially against infections due to encapsulated bacteria, is effective in Bruton-type, sex-linked, congenital agammaglobulinemia, agammaglobulinemia associated with thymoma, and acquired agammaglobulinemia.

Treatment of neonatal sepsis with intravenous immune globulin. [2011.09.29]
BACKGROUND: Neonatal sepsis is a major cause of death and complications despite antibiotic treatment. Effective adjunctive treatments are needed. Newborn infants are relatively deficient in endogenous immunoglobulin. Meta-analyses of trials of intravenous immune globulin for suspected or proven neonatal sepsis suggest a reduced rate of death from any cause, but the trials have been small and have varied in quality... CONCLUSIONS: Therapy with intravenous immune globulin had no effect on the outcomes of suspected or proven neonatal sepsis.

Clinical Trials Related to Baygam (Immune Globulin Human)

Phase II Study of Intravenous Immunoglobulin (IVIg) for Alzheimer's Disease [Active, not recruiting]
The overall goal of this double-blind Phase II study is to evaluate the safety, efficacy and biological mechanisms of action of Intravenous Immunoglobulin (IVIg) in the treatment of mild to moderate stage Alzheimer's disease (AD). IVIg contains antibodies against the amyloid beta protein that is the central component of the AD senile plaque. It is hypothesized that IVIg treatment will reduce the levels of beta amyloid in the brain and improve cognitive abilities relative to placebo. A total of 24 patients with mild to moderate AD capable of giving informed consent will be randomly assigned to receive either IVIg (16 patients)or saline placebo (8 patients) for six months. This study includes comparison of four dosing regimens of IVIg. Cognitive, behavioral and functional measures will be collected at baseline, three months and six months of treatment and after a six-week washout period. Plasma samples will be collected before and after infusions. Subjects will undergo a lumbar puncture before and after the six months of treatment for cerebrospinal fluid (CSF) biomarker analyses. In addition, Positron Emission Tomography (PET) imaging substudies will be performed at two time points during the study. Following the initial 6 month placebo-controlled period, all participants have the opportunity to receive IVIg for an additional 6 month period.

Intravenous Immunoglobulin After Relapse in Vasculitis [Terminated]

Treatment of Childhood Onset Psychiatric Disorders With Intravenous Immunoglobulin (IVIg) [Completed]
Recent research studies of early onset-obsessive compulsive disorder (OCD) and Tourette's syndrome have questioned whether autoimmunity could play a role in the development of these conditions. As a result, there has been an increased interest in the field of research on the potential involvement of autoimmunity in other psychiatric conditions like schizophrenia.

Autoimmune conditions occur when the normal immune system of the body begins working against itself. The immune system recognizes cells as foreign and begins to attack them.

There are several similarities between autoimmune diseases and schizophrenia. Genetics play some role in the development of both diseases. Both conditions show a similar course, and both conditions tend to show worsening of symptoms when exposed to stress.

Previous research studies have shown intravenous immunoglobulin to be safe and effective when used in neurologic diseases involving the immune system. Presently the NIMH is testing the effectiveness of IVIg in OCD and Tourette's syndrome.

Intravenous Immunoglobulin IVIg is a medication that has been used to treat diseases like Kawasaki disease, systemic juvenile rheumatoid arthritis, lupus nephritis, and idiopathic thrombocytopenic purpura. The drug modifies the body's natural immune reactions.

This research study is a 13-week trial of intravenous immunoglobulin (IVIg) on patients suffering from childhood-onset schizophrenia, who have failed to respond to other therapies.

Efficacy of High-Dose Intravenous Immunoglobulin Therapy for Hyperbilirubinemia Due Rh Hemolytic Disease [Recruiting]
The use of intravenous immunoglobulin G (IVIG) therapy has been reported in hyperbilirubinemia of Rh hemolytic disease but we don't have enough evidences for it. Human Immunoglobulin is considered an alternative to delay the hemolytic process and consequently reduce the number of exchange transfusions and transfusions of red cells concentrate, thus diminishing the risk of transmitting transfusional therapies-related diseases. OBJECTIVE: To determine the effect of IVIG in decreasing the incidence and severity of neonatal immune hemolytic jaundice due to Rh hemolytic disease reducing the need for exchange transfusion as a primary goal in these babies. METHODS: This will be a randomized, double blind, clinical trial involving all newborns with risk of significant hyperbilirubinemia due to direct Coombs-positive Rh hemolytic disease. The primary goal will be need for exchange transfusion and others are: incidence of late anemia, kernicterus and deafness Babies were randomly assigned into two groups: group 1 (study group) received phototherapy plus IVIG (500 mg/kg); and group 2 (control group) received phototherapy and normal saline solution (10 ml/Kg) in the first 6 hours of life. Exchange transfusion was carried out in any group if at any time the bilirubin level reached 340 micromol/l (20 mg/dl) or more, or rose by 8. 5 micromol/l per h (0. 5 mg/dl per h) in group 2. Adverse effects will be related in two groups. Parents informed consent will be asked in pre-natal time.

Intravenous Immunoglobulin (IVIg) for the Treatment of Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) [Completed]
Chronic Inflammatory Demylinating Polyneuropathy (CIDP) is an autoimmune condition affecting the nervous system. Researchers believe the immune system begins attacking the cells covering nerves called myelin. The destruction of myelin causes muscle weakness, loss of sensation, abnormal levels of protein in the fluid surrounding the brain (CSF), and slowing of the nervous system. The disease progresses slowly and disables patients suffering from it.

CIDP is treated with steroids, plasmapheresis, and immunosuppressive drugs. Many patients initially respond to these treatments, but develop resistance to the therapy or experience side effects causing the treatments to be stopped.

Researchers believe that intravenous immunoglobulin (IVIg) may provide patients with CIDP a safer and more effective alternative to standard therapies for the disease. IVIg is a drug that has been used successfully to treat other immune-related diseases of the nervous system. However, because IVIg is so expensive, researchers believe it should first be proven effective on a small group of patients.

The study will take 60 patients with CIDP and divide them into two groups. Group one will receive 2 injections of IVIg once a month for three months. Group two will receive 2 injections of placebo "inactive injection of sterile water" once a month for three months. Following the three months of treatment, group one will begin taking the placebo and group two will begin taking IVIg for an additional 3 months. The drug will be considered effective if patients receiving it experience a significant improvement (>25%) in muscle strength.
