Lupus anticoagulant which in the past was regarded as a laboratory nuisance is now known to be associated with numerous clinical conditions including thrombosis and recurrent foetal loss, however, no work has been done to assess its prevalence in non-pregnant healthy multiparous women. Our aim therefore was to determine the prevalence of lupus anticoagulant in non-pregnant multiparous Nigerian women of childbearing age. Fifty non-pregnant multiparous women who were considered healthy following verbal interviews were studied. An eligibility criterion was used. Coagulation studies were performed on plasma samples from all the women using the Kaolin clotting time. Mixing experiments were conducted on samples with prolonged clotting time to detect the presence of the lupus anticoagulant. The Kaolin clotting time ratio of greater than or equal to 1.2 was considered positive for the lupus anticoagulant. Forty-four (88%) of the 50 women had a normal cloning time, 2(4%) had subnormal clotting time while 4(8%) of them had a prolonged Kaolin clotting time. Mixing experiments on these 4 samples revealed Kaolin clotting time ratios of over 1.2, signifying the presence of the lupus anticoagulant (i.e. 8 per cent prevalence) among the population of women studied Multiparous women with the lupus anticoagulant may not be symptomatic therefore the anticoagulant should be screened for in women with unexplained prolongation of cloning time. We recommend that these women should be followed up especially in pregnancy to forestall any of the obstetric complications that have been associated with the lupus anticoagulant.
