Intramuscular administration of autologous total immunoglobulin G induces immunomodulatory effects on T cells in healthy human subjects: An open-labeled prospective single-arm trial.

Background: We hypothesized that intramuscular administration of autologous total immunoglobulin G (IgG) could induce an immunomodulatory effect in human subjects. In our previous studies, we showed that intramuscular administration of autologous total IgG could induce significant clinical improvements and increases of the serum levels of interleukin-10 (IL-10) and interferon-gamma (IFN-γ) in patients with atopic dermatitis.

Objective: To investigate the mechanism of immunomodulation induced by intramuscular administration of autologous total IgG, we evaluated changes in T cells before and after intramuscular administrations of autologous total IgG in this study.

Efficacy, Safety, and Immunomodulatory Effect of the Intramuscular Administration of Autologous Total Immunoglobulin G for Atopic Dermatitis: A Randomized Clinical Trial.

Purpose: The management of patients with atopic dermatitis (AD) is often difficult. We hypothesized that repeated intramuscular administration of autologous total immunoglobulin G (IgG) could induce clinical improvement in patients with AD through immune modulation. This clinical trial was conducted to evaluate the efficacy, safety, and immunomodulatory effect of the intramuscular administration of autologous total IgG in patients with AD.

Immunomodulatory effects induced by intramuscular administration of autologous total immunoglobulin G in patients with atopic dermatitis.

Background: Polyvalent human immunoglobulin G (IgG) preparations produced from the plasma pools of healthy blood donors have been used for the treatment of various autoimmune diseases and allergic diseases because of their anti-inflammatory and immunomodulatory effects. We hypothesized that intramuscular administration of autologous total IgG would induce immunomodulatory effects in patients with allergic diseases, based on the clinical efficacy of autologous blood therapy in patients with atopic dermatitis (AD).

Methods: Sixteen adult AD patients with IgE-mediated sensitization to the house dust mite (Dermatophagoides farinae) received intramuscular injections of 50 mg autologous total IgG twice a week for 4 weeks.

Clinical Efficacy of Subcutaneous Allergen Immunotherapy in Patients with Atopic Dermatitis.

Purpose: The clinical usefulness of subcutaneous allergen immunotherapy (SCIT) in the treatment of atopic dermatitis (AD) is still controversial. We analyzed the clinical efficacy of SCIT in patients with AD and the clinical characteristics of patients showing a favorable clinical response to the treatment.

Materials And Methods: Two hundred and fifty one patients with AD sensitized to house dust mite (HDM) were treated by SCIT using HDM extract.

Autologous Immunoglobulin Therapy in Patients With Severe Recalcitrant Atopic Dermatitis: Long-Term Changes of Clinical Severity and Laboratory Parameters.

This report evaluated long-term changes in clinical severity and laboratory parameters in 3 adult patients with severe recalcitrant atopic dermatitis (AD) who were treated with intramuscular injections of 50 mg of autologous immunoglobulin G (IgG) twice a week for 4 weeks (autologous immunoglobulin therapy, AIGT) and followed up for more than 2 years after the treatment. We observed the following 4 major findings in these 3 patients during the long-term follow-up after AIGT. (1) Two of the 3 patients showed a long-term clinical improvement for more than 36 weeks after AIGT with a maximum decrease in clinical severity score greater than 80% from baseline.

Effects of Intramuscular Injection of Autologous Immunoglobulin on Clinical Severity and Serum IgE Concentration in Patients with Atopic Dermatitis.

Background/objective: The management of patients with atopic dermatitis (AD) is often difficult for both patients and physicians. We hypothesized that repeated intramuscular injections of autologous immunoglobulin can induce clinical improvement in patients with AD by correcting immune dysfunction.

Methods: Seventeen adult patients with severe AD were treated by intramuscular injection of 50 mg autologous immunoglobulin (mainly IgG with a purity ≥97%) twice a week for 4 weeks.

Autologous immunoglobulin therapy in patients with severe recalcitrant atopic dermatitis: a preliminary report.

The management of severe recalcitrant atopic dermatitis (AD) is a challenging issue for clinicians and patients. We hypothesized that repeated intramuscular injections of autologous immunoglobulin (autologous immunoglobulin therapy: AIGT) might induce clinical improvements in patients with AD by stimulation of the active immune response to antigen-binding-site of pathogenic antibodies. We tried AIGT in 3 adult patients with severe recalcitrant AD whose clinical conditions could not be effectively controlled by medical treatments (including oral cyclosporine) for more than 2 years.

Clinical efficacy of autologous plasma therapy for atopic dermatitis.

Background: The clinical efficacy of autologous blood therapy (ABT) in patients with atopic dermatitis (AD) was demonstrated by a randomized double-blind placebo-controlled study. To characterize the blood component mediating the therapeutic efficacy of ABT for AD, we evaluated the clinical efficacy of autologous plasma therapy (APT) and autologous high-molecular-weight plasma protein fraction therapy (AHPT) in patients with AD in this study.

Methods: A total of 22 patients with recalcitrant AD were treated with 8 weekly intramuscular injections of either autologous plasma (n = 11) or autologous high-molecular-weight plasma protein fraction (n = 11) for 7 weeks.
