Prevalence of anticardiolipin antibody in Bangladeshi patients with recurrent pregnancy loss
The objective of the present study was to see the prevalence of anticardiolipin antibody (ACA) in Bangladeshi patients (35) with recurrent pregnancy loss. Thirty-seven women with normal pregnancy were included as control. Serum levels (mean ± SD) of ACA (u/mL) was significantly higher, whereas ANA (Ab-index) and anti-dsDNA (Ab-index) were similar in cases compared to controls (Cases vs Controls g ACA: 31.8 ± 24.3 vs 10.5 ± 3.4, p<0.001; ANA: 1.07 ± 0.34 vs 0.92 ± 0.15, p>0.5; A-dsDNA: 0.53 ± 0.16 vs 0.52 ± 0.18, p>0.5). The cases positive for ACA, ANA and anti-dsDNA were 37.1% (p<0.001), 20% (p>0.05) and 2.8% (p>0.1) respectively. Among the seropositive cases 4/35 (11.4%) and 4/13 (30.8%) were positive for both ACA and ANA. In controls only 2/37 (5.4%) and 2/37 (5.4%) were positive for ACA and ANA respectively and none were positive for both ACA and ANA together simultaneously. Significantly high proportion of cases had O positive blood group (23/35: 65.7%, 10/13: 76.9%) (p<0.01). The prevalence of ACA varies according to population being 37.1% (13/35) in our patients with recurrent pregnancy loss and 5.4% in controls.Online: 13 July 2010DOI: http://dx.doi.org/10.3329/bmrcb.v36i1.5446Bangladesh Med Res Counc Bull 2010; 36: 10-13
