Study carried out to evaluate the rate of obstetric complications and the weight of adverse obstetric out-come in women with antiphospholipid syndrome (APS), in asymptomatic antiphospholipid antibody (aPL) carriers, and in subjects with non-criteria APS. Data were collected from 2013 to 2018 and 163 controls (pregnant women with aPL antibodies) and 785 controls (aPL negative pregnant women) were enrolled. The penalized logistic regression was used to compare obstetric complications. Cases included 62 carriers of complete APS (38%), 48 carriers of non-criteria APS (29.4%) and 53 (32.5%) carriers of asymptomatic aPL. Connective tissue diseases (CTD) were diagnosed in 31.3% of cases. The high-risk aPL profile rate was higher (p <.01) in subjects with complete APS (67.7%) than in non-criteria (14.6%) and asymptomatic aPL carriers (9.4%). Double / triple positivity, risk factor for the development of negative out-come, was 33.9% among subjects with complete APS (p <0.05 compared to non-criteria and aPL carriers), 10, 4% in non-criteria subjects and 9.4% in asymptomatic carriers of aPL. The negative out-come rate of pregnancy was 5.6% in controls, 41.9% (OR = 6.95% CI = 2.7-13.5) in complete APS, 25% ( OR = 4.4.95% CI = 2-9.4) in non-criteria patients and 28.3% (OR = 4.95% CI = 1.8-8.8) in asymptomatic aPL carriers. CTDs were independently associated with an increased risk of adverse obstetric outcomes (OR = 2.8.95% CI = 1.36-5.89). The attributable fraction (AF) of obstetric adverse events was higher among subjects with low-risk antibodies versus high-risk antibodies (AF = 0.27.95% CI = 0.22-0.31 vs AF = 0.16, 95% CI = 0.16-0.2, p <. 01) and between single positive vs double / triple positive (AF = 0.32.95% CI = 0.26-0.37 vs AF = 0, 11.95% CI = 0.09-0.13, p <0.01) suggesting that low-risk subjects are responsible for a high burden of obstetric complications.
Studio svolto al fine di valutare il tasso di complicanze ostetriche e il peso degli out-come ostetrici avversi nelle donne con sindrome da antifosfolipidi (APS), nei carriers di anticorpi antifosfolipidi asintomatici (aPL), e nei soggetti con APS non-criteria. I dati sono stati raccolti dal 2013 al 2018 e sono state arruolate 163 controlli (donne in gravidanza con anticorpi aPL) e 785 controlli (donne in gravidanza negative per gli aPL). La regressione logistica penalizzata è stata utilizzata per confrontare le complicanze ostetriche. I casi includevano 62 portatori di APS completo (38%), 48 portatori di APS non-criteria (29,4%) e 53 (32,5%) carriers di aPL asintomatici. Le malattie del tessuto connettivo (CTD) sono state diagnosticate nel 31,3% dei casi. Il tasso di profilo aPL ad alto rischio era più alto (p <.01) nei soggetti con APS completo (67,7%) rispetto ai non-criteri (14,6%) e ai carriers asintomatici di aPL (9,4%). La doppia/tripla positività, fattore di rischio per lo sviluppo di out-come ostetrici negativi, è stata del 33,9% tra i soggetti con APS completa (p <0,05 rispetto a portatori non-criteria e aPL), 10,4% nei soggetti non-criteria e 9,4% nei carriers asintomatici di aPL. Il tasso di out-come negativi della gravidanza è stato del 5,6% nei controlli, del 41,9% (OR = 6,95% CI = 2,7-13,5) nell'APS completo, del 25% (agg. OR = 4,4,95% CI = 2-9,4) nei pazienti non-criteria e 28,3% (OR = 4,95% CI = 1,8-8,8) nei carriers asintomatici di aPL. I CTD erano associati in modo indipendente a un aumento del rischio di esiti ostetrici avversi (OR = 2,8,95% CI = 1,36-5,89). La frazione attribuibile (AF) di eventi ostetrici avversi era più alta tra gli anticorpi a basso rischio rispetto a quelli ad alto rischio (AF = 0,27,95% CI = 0,22-0,31 vs AF = 0,16,95% CI = 0,16-0,2, p <. 01) e tra positività singola rispetto a positività doppia / tripla (AF = 0,32,95% CI = 0,26-0,37 vs AF = 0,11,95% CI = 0,09-0,13, p <0,01) suggerendo che i soggetti a basso rischio sono responsabili per un elevato carico di complicanze ostetriche.

Abstract
Study carried out to evaluate the rate of obstetric complications and the weight of adverse obstetric out-come in women with antiphospholipid syndrome (APS), in asymptomatic antiphospholipid antibody (aPL) carriers, and in subjects with non-criteria APS. Data were collected from 2013 to 2018 and 163 controls (pregnant women with aPL antibodies) and 785 controls (aPL negative pregnant women) were enrolled. The penalized logistic regression was used to compare obstetric complications. Cases included 62 carriers of complete APS (38%), 48 carriers of non-criteria APS (29.4%) and 53 (32.5%) carriers of asymptomatic aPL. Connective tissue diseases (CTD) were diagnosed in 31.3% of cases. The high-risk aPL profile rate was higher (p <.01) in subjects with complete APS (67.7%) than in non-criteria (14.6%) and asymptomatic aPL carriers (9.4%). Double / triple positivity, risk factor for the development of negative out-come, was 33.9% among subjects with complete APS (p <0.05 compared to non-criteria and aPL carriers), 10, 4% in non-criteria subjects and 9.4% in asymptomatic carriers of aPL. The negative out-come rate of pregnancy was 5.6% in controls, 41.9% (OR = 6.95% CI = 2.7-13.5) in complete APS, 25% ( OR = 4.4.95% CI = 2-9.4) in non-criteria patients and 28.3% (OR = 4.95% CI = 1.8-8.8) in asymptomatic aPL carriers. CTDs were independently associated with an increased risk of adverse obstetric outcomes (OR = 2.8.95% CI = 1.36-5.89). The attributable fraction (AF) of obstetric adverse events was higher among subjects with low-risk antibodies versus high-risk antibodies (AF = 0.27.95% CI = 0.22-0.31 vs AF = 0.16, 95% CI = 0.16-0.2, p <. 01) and between single positive vs double / triple positive (AF = 0.32.95% CI = 0.26-0.37 vs AF = 0, 11.95% CI = 0.09-0.13, p <0.01) suggesting that low-risk subjects are responsible for a high burden of obstetric complications.È consentito all'utente scaricare e condividere i documenti disponibili a testo pieno in UNITESI UNIPV nel rispetto della licenza Creative Commons del tipo CC BY NC ND.
