[Therapeutic administration of immunoglobulins].

BACKGROUND: Intravenously administered immunoglobulins have multiple modes of action that are anti-inflammatory. They can therefore be beneficial in a number of autoimmune disorders.
OBJECTIVE: The aim of this article is to analyze and summarize studies on the administration of intravenous immunoglobulins in rheumatological diseases.
METHODS: A selective search and analysis of the literature was carried out related to the mode of action and efficacy of intravenous immunoglobulins in rheumatological diseases. RESULTS AND
CONCLUSION: Intravenous immunoglobulins have a broad mode of action and can therefore be beneficial in almost all autoimmune diseases. Conditions in which they are of special benefit include immunothrombopenia (ITP), Kawasaki disease and idiopathic inflammatory myopathies. In rare situations, they may also be indicated in systemic lupus erythematosus (SLE), Sjögren's syndrome and neuropathies, catastrophic antiphospholipid syndrome (APS), scleroderma, antineutrophil cytoplasmic antibody (ANCA) associated vasculitis, pyoderma gangrenosum and scleromyxedema. Severe adverse events are rare. In view of the high costs of the therapy, intravenous immunoglobulins are mostly applied in emergency situations, as salvage therapy when other standard therapies have failed or when severe infections are a contraindication to the administration of immunosuppressants.
