Abstract
Antiphospholipid antibodies (АPА) and anti-idiotypic
antiphospholipid antibodies (AiAPA) were studied in 148
women subjected to IVF. АPА (IgG аCL, аPS,) levels in serum
have been defined. Sera IgG fraction was also examined for the
presence of AiAPA by three different methods: 1) binding of
AiAPA with mouse monoclonal cofactor-independent APA
(mAPA) immobilized on plate; 2) AiAPA neutralization of
human affinity isolated APA and 3) mAPA binding with phos-
pholipids. Significant difference in AiAPA levels between APA+
and APA- women subjected to IVF have been found. The mean
level of AiAPA was lower in APA+ women subjected to IVF
than in APA- women from the same group (p<0,05). IV infusion
of Ig decreased the APA level significantly as well as increased
the AiAPA level in APA+ women subjected to IVF. Ig applica-
tion to incubation in vitro results in decrease of APA levels in
serum. Results of this study confirmed possibility of AiAPA
participation in down regulation of cofactor-independent APA
production in women undergoing to IVF.
