IVIg therapy is a versatile treatment option with applications across various medical conditions. While it has shown efficacy in reducing infections, improving muscle strength, and modulating immune responses, the cost-effectiveness and long-term benefits of IVIg require further investigation. Clinicians should consider the specific clinical context and available evidence when deciding on IVIg treatment.
Intravenous Immunoglobulin (IVIg) therapy is a treatment modality that involves the administration of immunoglobulins through an intravenous route. This therapy has been employed in various medical conditions, ranging from autoimmune diseases to infections. Here, we explore the key aspects of IVIg treatment, its applications, and the evidence supporting its use.
Mechanism of Action
IVIg is composed of pooled immunoglobulin G (IgG) antibodies extracted from the plasma of thousands of donors. These antibodies can modulate the immune system in several ways, including neutralizing pathogens, modulating immune cell function, and altering the production of inflammatory cytokines.
Applications of IVIg
Chronic Lymphocytic Leukemia (CLL)
In patients with chronic lymphocytic leukemia (CLL), IVIg has been shown to reduce the incidence of infections. A crossover study demonstrated that low-dose IVIg prophylaxis significantly lowered the incidence of infectious episodes in CLL patients with hypogammaglobulinemia or a history of severe infections1. However, the study also noted that this low-dose treatment might not be cost-effective for preventing infections in CLL patients.
Streptococcal Toxic Shock Syndrome (STSS)
IVIg has been evaluated as an adjunctive therapy in streptococcal toxic shock syndrome (STSS). A European randomized, double-blind, placebo-controlled trial found that high-dose IVIg significantly decreased sepsis-related organ failure scores and increased plasma neutralizing activity against superantigens2. Although the primary endpoint of mortality reduction was not statistically significant due to the small sample size, the results support the efficacy of IVIg in STSS.
Multifocal Motor Neuropathy (MMN)
High-dose IVIg has been effective in treating multifocal motor neuropathy (MMN). A double-blind, placebo-controlled study confirmed that IVIg treatment improved muscle strength in patients with MMN, whereas placebo did not3. This suggests that IVIg can be a valuable treatment option for MMN.
Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP)
IVIg is recommended as a first-line treatment for chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). Studies have shown that IVIg leads to rapid improvement in CIDP patients, although it does not typically result in long-term remission4 5. Combining IVIg with corticosteroids may enhance long-term remission rates, as suggested by ongoing research4.
Painful Diabetic Polyneuropathy (DPN)
For patients with painful diabetic polyneuropathy (DPN) resistant to conventional treatments, high-dose IVIg has shown efficacy. A multicenter trial demonstrated that IVIg significantly reduced pain intensity and improved quality of life in DPN patients compared to placebo6.
Motor Neuron Syndromes
IVIg has also been studied in motor neuron syndromes associated with anti-GM1 antibodies. A double-blind, placebo-controlled trial found that IVIg significantly increased muscle strength in patients with conduction blocks, highlighting its potential benefit in this subgroup7.
Multiple Sclerosis (MS)
IVIg treatment following the first demyelinating event suggestive of multiple sclerosis (MS) has been shown to reduce the incidence of a second attack and disease activity. A randomized, double-blind, placebo-controlled trial reported that IVIg significantly lowered the probability of developing clinically definite MS and reduced lesion volume on MRI8.
Juvenile Rheumatoid Arthritis (JRA)
In systemic juvenile rheumatoid arthritis (JRA), IVIg has been assessed for its efficacy and safety. Although a randomized, placebo-controlled trial indicated some improvement in the IVIg group, the small sample size and lack of statistical significance suggest limited clinical utility9.
Cardiomyopathy
IVIg has been investigated in patients with idiopathic chronic cardiomyopathy and cardiac parvovirus B19 persistence. A randomized, double-blind, placebo-controlled trial aimed to determine the benefits of IVIg beyond conventional therapy, although further research is needed to establish its efficacy in this context10.
