What is IVIG in a patient?
IVIG contains natural IgG antibodies which are germline encoded and occur in the absence of infection or vaccination and the importance of these has been demonstrated in a study into the in vitrodifferentiation of dendritic cells (DCs) from patients with X-linked agammaglobulinaemia who lack B cells and antibodies. Differentiation of DCs was shown to be impaired, and the defect was reversed by natural antibodies reactive with CD40 [15]. Anti-idiotypes present in IVIG may also be responsible for the success of IVIG treatment of ITP; IVIG prepared from multiparous women contains many more anti-idiotypes to human HLA antigens, and can inhibit alloimmunization to HLA [16]. IVIG may also contain antibodies to a range of immunologically important molecules such as interleukin (IL)-1α, tumour necrosis factor (TNF)-α and interferon (IFN)-γ[17–19] as these have been demonstrated in the sera of healthy individuals. IVIG contains antibodies against the beta chain of the T cell receptor and also against CD5 and CD4 [20–22]

What is MG in medical terms?
Myasthenia gravis (MG), an archetypal autoimmune neurological disorder is characterized by fluctuating, fatiguable muscle weakness caused by antibodies to the acetylcholine receptor. The only RCT [55] to date showed that IVIG was as effective as plasma exchange for myasthenic exacerbations.
When was immunoglobulin replaced?
At the inception of immunoglobulin replacement for primary antibody deficiency (PAD) in the 1950s no studies comparing intramuscular immunoglobulin (IMIG) with either placebo or a no treatment arm were contemplated or undertaken because immunoglobulin replacement made intuitive good sense in patients with endogenous B cell failure. Indeed, when the UK Medical Research Council trial of the efficacy of immunoglobulin replacement therapy in hypogammaglobulinaemia was set up in 1955 it was felt that a placebo arm would be unethical because of strong presumptive evidence from the United States that Ig replacement was effective in decreasing the frequency of infections in hypogammaglobulinaemia.
Does IVIG reduce adhesion?
IVIG has also been shown to reduce adhesion of T cells to extracel lular matrix following activation by phytohaemagglutinin (PHA) or phorbol myristate acetate (PMA) [13] and contains antibodies to the Arg-Gly-Asp (RGD) motif, the attachment site for a number of adhesive extracellular matrix proteins and β1, β3 and β5 integrins [14].
Does IVIG inhibit apoptosis?
In addition in atopic dermatitis T cell-mediated, Fas-induced keratinocyte apoptosis is inhibitied by IVIG [10]. Additional studies show that IVIG causes the arrest of cells at the G0/G1 phase of the cell cycle, and inhibits cells from entering S-phase [11]. In contrast to these studies IVIG has been demonstrated to induce apoptosis in leukaemic lymphocytes and monocytes as well as normal tonsillar B cells, an effect mediated at least in part by anti-CD95 antibodies present within the IVIG preparations [12]. Taken together, these studies show that although IVIG appears to be broadly anti-apoptotic and cause cell cycle arrest, under certain conditions it may also induce apoptosis.
Does IVIG contain cytokines?
IVIG itself may contain cytokines and other molecules including soluble cytokine inhibitors, soluble CD4 and major histocompatibility complex (MHC) class II [38]. Stabilizing agents, mainly various sugars, can also exert an effect, both maltose and sucrose, at concentrations present in commercial IVIG preparations, can inhibit PHA- and to a lesser extent, PMA-induced proliferative responses in vitro[39] (reviewed in [2]).
How is IVIG given?
IVIg is given through a drip into a vein, this is known as intravenous infusion. It is sometimes given as an injection into a muscle if you’re only taking it to increase your immunoglobulin levels following other treatments.
What is IVIG used for?

What is IVIG in medicine?
Intravenous immunoglobulin (IVIG) is a concentrate of the pooled immunoglobulins derived from 1000 to 100000 healthy donors depending upon the manufacturer . Immunoglobulins play a pivotal role in humoral adaptive immunity; ergo, IVIG reflects a collective exposure of the donor population to their environment and can be expected to contain an antibody repertoire of multiple specificities against a broad spectrum of infectious agents (bacterial, viral, and others), self-antigens and anti-idiotype antibodies.
What is IVIG in plasma?
The composition of IVIG products closely corresponds to that of immunoglobulins in the normal human plasma, especially IgG (along with its subclasses), IgA, traces of other Igs, cytokines, and soluble receptors. IVIG products are prepared using the Cohn-Oncley procedure, the first step of which is cold ethanol precipitation used to enrich the IgG from the plasma of donors. Any two IVIG product varies with respect to the presence of excipients such as substances used to stabilize proteins and prevent aggregation of IgG (sugars such as glucose, maltose, D-sorbitol or more recently amino acids such as glycine or proline), sodium levels, pH levels, osmolality and other immunoglobulins (for example, IgA can vary from 0.06 mg to 40 mg in different preparations). [6]
Why is IgG important?
IgG levels in blood serve as an essential yardstick to guide IVIG therapy. It is also used to assess the effectiveness of the treatment and helps to modify the IVIG course and frequency. Measuring IgG levels at different times to evaluate the peak plasma levels and trough levels can assess response to therapy.
How does IVIG work?
In humoral immunodeficiencies, IVIG primarily acts by substituting for the lack of IgG and confers passive immunity by neutralizing bacterial toxins and viruses through the Fab portion. They also help activate the complement cascade at low doses by specific interaction with pathogens , a function that reverses in high doses to complement inactivation by non-specific interactions. [23] Polyvalent IVIG products with a higher number of donors would contain a much larger spectrum of specificities and would be more efficient in immune replacement therapies. [24] The effects of replacement dose IVIG in PIs are observable well beyond the half-life of IgG administered, suggesting the induction of active immunity. [25] This is exemplified by the activation of cellular immunity; for example, IVIG modulates T cell immunity in PIs and increases CD4 counts in CVID, induces B cell immunoglobulin production in CVID patients, and induces dendritic cell (DC) maturation. [26] [27] [28]
How is IVIG administered?
The most common means of administration is as a single intramuscular dose after the suspected exposure to a particular pathogen, and the earlier it is administered after exposure, the better the outcome. In addition to the intramuscular route, some of these immune sera are given as IVIG therapy. They may also be administered in a multi-dose regimen; for example, 750 mg/kg of respiratory syncytial virus (RSV) IVIG is given every month to infants in RSV season. The dosage can also increase in cases of immunocompromised and immunosuppressed patients. [18]
How much IVIG should I take?
High-dose immunomodulatory and anti-inflammatory therapy: For immunomodulation, higher doses of IVIG are necessary, ranging from 1000 to 3000 mg/kg of body weight to achieve peak plasma concentrations of 2500 to 3500 mg/dL. The optimal dosage, duration, and frequency are usually determined based on the indication, response to treatment, adverse effects, relapse rate, infectious episodes, patient preferences, and affordability. In general, a high-dose IVIG protocol, usually but not always, involves an initial dose, maintenance dose, tapering/intensifying dose, and discontinuation. [63] In general, a protocol of 2 mg/kg/course divides into 400 mg/day for five days and is a universally employed administration strategy for autoimmune diseases. [64] It is modifiable in certain conditions; for instance, in the case of ITP, a dose of 1000 mg/kg is given for 1 to 2 days. [65] Weekly regimens may also be employed depending on the clinical situation and the particular patient. [63]
What is IVF treatment?
In vitro fertilization (IVF) is a treatment for infertility or genetic problems.

How long does it take to get pregnant with IVF?
IVF has many steps, and it takes several months to complete the whole process. It sometimes works on the first try, but many people need more than 1 round of IVF to get pregnant. IVF definitely increases your chances of pregnancy if you’re having fertility problems, but there’s no guarantee — everyone’s body is different and IVF won’t work for everyone.
How long does it take for an embryo to be put in the uterus?
About 3-5 days after the egg retrieval, 1 or more embryos are put into your uterus (this is called embryo transfer). The doctor slides a thin tube through your cervix into your uterus, and inserts the embryo directly into your uterus through the tube. Pregnancy happens if any of the embryos attach to the lining of your uterus.

Most products also contain some immunoglobulin A and trace amounts of other plasma proteins.
What is an off label IVIG?
Off-Label Uses of IVIG. Using a drug for an “off-label” purpose means to use it for something other than what it has been approved for. For example, aspirin is approved to relieve pain or reduce fever, but, because of other properties that aspirin has, many doctors suggest taking one aspirin per day to reduce the risk of heart attack.
When did intravenous therapy become the standard treatment?
The U.S. licensed preparations that could be safely administered intravenously in the early 1980s. Larger doses could be given through the intravenous route and more closely matched the body’s own antibody production. Most patients tolerated this type of treatment well, and it soon became the standard treatment for patients suffering from primary immunodeficiencies with antibody deficiency.
