Description
Summary:Transforming growth factor-beta (TGF-beta), a multifunctional, immunosuppressive cytokine, is shown to be present in substantial amounts in commercially available intravenous immunoglobulin (IVIG) preparations. To assess whether TGF-beta isoforms are changed in the plasma of paediatric patients with childhood autoimmune diseases after IVIG infusion, 17 patients who received over a period of 12 months overall 56 IVIG infusions (Endobulin) were enrolled in a study. High levels of TGF-beta1 (16.95 +/- 8.16 ng/ml) as well as TGF-beta2 (62.71 +/- 9.50 ng/ml) were detected in the used 56 IVIG probes. TGF-beta1 and TGF-beta2 plasma concentrations were measured prior and 120 min after IVIG infusions by specific TGF-beta ELISA. Interestingly, significant increased TGF-beta1 and TGF-beta2 plasma levels were found in patients after treatment with IVIG. This data suggest that a TGF-beta-mediated mechanism of action may accompany other molecular effects of IVIG therapy. The amount of the potent anti-inflammatory TGF-beta isoforms within the IVIG preparations may exert a differentiated view regarding the manifold indications of IVIG therapy.
