A. Achiron et al., INTRAVENOUS IMMUNOGLOBULIN TREATMENT IN MULTIPLE-SCLEROSIS AND EXPERIMENTAL AUTOIMMUNE ENCEPHALOMYELITIS - THE ISRAELI EXPERIENCE, Multiple sclerosis, 3(2), 1997, pp. 142-144
Intravenous immunoglobulin (IVIg) has been shown to be beneficial in t
he treatment of several autoimmune disorders both in humans and in ani
mal models. IVIg has been applied for the treatment of multiple sclero
sis (MS). One of the major advantages of IVIg treatment in MS is that
it can affect several mechanisms that have been proposed to be involve
d in the pathogenesis of the disease, including: suppression of T-cell
activation, Fc receptor blockade, modulation of cytokine production,
T-cell receptor blockade and masked recognition of class II MHC (D/DR)
.(1-4) In addition to its immunological effects, IVIg can penetrate th
e blood-brain barrier,(5) and produce a direct effect on myelin format
ion.(6,7) This is of major importance in MS, wherein myelin breakdown
and destruction at the edges of expanding plaques leads to accumulatin
g neurological disability. The possibility of IVIg to influence severa
l mechanisms involved in the disease process is advantageous because t
he treatment might have different effects in different stages of the d
isease, and even in the same patient influencing several simultaneousl
y ongoing processes. In the present review the clinical and experiment
al data related to experience gained by the Israeli MS Study Group wit
h IVIg treatment in MS and EAE will be summarized.
