Patient characteristics
Among 151 APS patients, there were 63(63.0%) females for PAPS, 45(88.2%) for SAPS, and the mean age for each were 36.3 and 32.9 years (Table 1). The mean age was 30.1 years in SLE group, of which 61(85.9%) were female, while HC group had 41(45.6%) female and a mean age of 43.4. Clinical manifestations were recorded for both APS and SLE patients and were selectively shown. Thrombosis was most commonly present, with 80(80.0%) for PAPS and 74.5% for SAPS, but not in SLE group. Patients were recorded for history of arterial or venous thrombotic events, pregnancy morbidity, microangiopathy, history of adverse pregnancy, and LA. Of all the clinical manifestations, prevalence of adverse pregnancy history was significant different between PAPS and SAPS group(χ2=3.922,P =0.048).
