The relationship between TORCH complex false positivity and obstetric outcome in patients with antiphospholipid syndrome
Lupus, 06/15/2012
De Carolis S et al. – The data suggest that the presence of Cytomegalovirus (CMV) IgM false positivity could represent a novel prognostic factor for poor pregnancy outcome in antiphospholipid syndrome (APS) patients.
Methods- Data from 54 pregnancies in women with antiphospholipid syndrome (APS) were assessed in comparison with data from 222 healthy pregnant women as controls.
- Each woman in both groups was systematically screened for TORCH IgG and IgM during pre–conceptional evaluation and/or at the beginning of pregnancy.
- The assessment of IgG avidity was also evaluated in order to identify primary infection or false positivity.
- A significant increase of CMV IgM false positivity in APS in comparison with controls was detected.
- A worse pregnancy outcome was observed among APS patients having CMV IgM false positivity in comparison with APS patients without false positivity; in particular a statistically significant lower neonatal birth weight and a lower neonatal birth weight percentile were observed.
