Antiphospholipid antibodies (aPL): lupus anticoagulant (LA), anticardiolipin antibodies (aCL) and anti-β2-glycoprotein I antibodies (anti-β2GPI) are found in 12 to 44% of systemic lupus erythematosus (SLE) patients. On average, antiphospholipid antibody syndrome (APS) develops in50% of aPL-positive patients with SLE. The seronegative APS is characterized by the absence of the diagnostic levels of "classical" aPL and by the presence of non-criteria aPL: antibodies against pro- thrombin (aPT), antibodies against annexin V, antibodies against phosphatidylethanoamine (aPE), antibodies to phosphatidylserine/prothrombin complex (aPS-PT) and antibodies against negatively charged phospholipids. The presence of four antibodies (LA + aCT + anti-β2GPI + aPT) is associated with a threefold increase in the risk of thrombosis. The presence of aCL and anti-β2GPI in SLE patients with APS and recurrent thromboses is associated with the HLA dRB1 * 0402.

Study objectives were to determine, in children with systemic lupus erythematosus (SLE), (1) the association of antiphosholipid antibody (APLA) subtypes with thrombotic events (TEs) and (2) the predictive value of persistent versus transient antibodies for TEs. This is a cohort study of 58 SLE children in whom lupus anticoagulants (LAs), anticardiolipin antibodies (ACLAs), anti–β2-glycoprotein-I (anti–β2-GPI), and antiprothrombin (anti-PT) were assessed on at least 2 occasions (more than 3 months apart). Antibodies were classified as persistent (positive on at least 2 occasions) or transient (positive once). Outcomes were symptomatic TEs confirmed by objective radiographic tests identified retrospectively and prospectively. Seven of the 58 patients (12%) had 10 TEs; 5 patients had TEs during prospective follow-up. Persistent LAs showed the strongest association with TEs (P < .001). Persistent ACLAs (P = .003) and anti–β2-GPI (P = .002) were significantly associated with TEs; anti-PT (P = .063) showed a trend. Persistent or transient LAs and anti–β2-GPI showed similar strength of association, while ACLAs and anti-PT were no longer associated with TEs. Positivity for multiple APLA subtypes showed stronger associations with TEs than for individual APLA subtypes because of improved specificity. Lupus anticoagulant is the strongest predictor of the risk of TEs; other APLA subtypes provide no additional diagnostic value. Anticardiolipin antibodies and anti-PT require serial testing because only persistent antibodies are associated with TEs.

Antiphospholipid syndrome (APS) is an autoimmune disease characterized by recurrent thrombotic events, miscarriages and thrombocytopenia with persistently positive antiphospholipid antibodies. 1 , 2 APS may be isolated (primary APS) or associated to a connective tissue disease, most often systemic lupus erythematosus (SLE). 1 , 2 APS usually affects young patients before the fifth decade 3 with stroke being the commonest neurological manifestation. 4 Various other neurological manifestations are being recognized in patients with APS including migraine, epilepsy, multi-infarct dementia and chorea. 2 The pathological process underlying the neurological manifestations remains obscure. 1 , 2 Herein we report a case of primary APSpresenting with a group of unusual neurological manifestations in a 68-year-old woman.

Abstract Background. The antiphospholipid syndrome (APS) is one of the most encountered autoimmunity in systemic lupus erythematosus (SLE) patients and pathogenesis of these two seems to be intricate. Aim. To investigate the association of antiphospholipid antibodies (APLAs) titer with the presence of secondary APS diagnosis in SLE patients. Methods. 65 patients fulfilling the 2012 Systemic Lupus Collaborating International Clinics (SLICC) SLE’s criteria were included. The APS diagnosis was sustained according to the 2006 Sydney APS’s criteria. Three groups of patients were defined: SLE patients with secondary APS, SLE with history of positive “criteria” APLAs but without APS clinical features, respectively SLE patients without positive APLAs or clinical APS criteria. An extended APLAs panel was searched in all cases: both IgM and IgG of anticardiolipin antibodies (aCL), anti-β2 glycoprotein I antibodies (aβ2GPI), antiphosphatidylethanolamine antibodies (aPE), antiphosphatidylserine antibodies (aPS), respectively antiprothrombin antibodies (aPT). Results. Only the aβ2GPI, both IgM and IgG serotypes, had significantly higher titers in patients with SLE and secondary APS compared to no APS (with/without positive APLAs): median (min; max) 7.0 (0.0-300.0) vs. 1.0 (0.0-28.0) vs. 1.0 (0.0-12.0), respectively 3.0 (0.0-79.0) vs. 1.0 (0.0-3.0) vs. 1.0 (0.0-12.0) (p<0.001, Kruskal-Wallis test)]. Also, in regression logistic models, only the aβ2 GPI (IgG and IgM) were identified as risk factors for secondary APS diagnosis in the SLE patients: OR(95%CI) 5.9 (2.2-15.7), respectively 1.3 (1.1-1.5). In regard with the SLE markers, the IgG serotypes of the “non-criteria” APLAs analyzed (aPS, aPT, aPE) were correlated with the antiDNA titers while the IgM serotypes inversely associated with the complement C3 levels. Conclusions. IgG aβ2 GPI are accompanied by almost 6-fold increase risk of secondary APS when screening SLE patients. On the contrary, the “non-criteria” APLAs do not seem associated with the APS diagnosis in SLE patients. Some correlates of the “non-criteria” APLAs with the antiDNA and complement C3 levels were also observed.

A high functioning 74-year-old man with systemic lupus erythematosus presented to the emergency department with acute anxiety. He was found to have elevated cardiac enzymes and admitted to the cardiology service for investigation. In hospital, he developed an erythematous papular rash, and deteriorated to being somnolent and bedridden. He was found to have new multiterritory ischaemic strokes. It was eventually noted that he had persistent eosinophilia, present even on admission, which had been overlooked as the total leucocyte count was normal. Serology for antiphospholipid antibody syndrome (APS) was positive. He was diagnosed with hypereosinophilic syndrome (HES) secondary to new APS, and responded to high-dose steroids. This case highlights the importance of fully evaluating a leucocyte differential to make a diagnosis of HES. We discuss the definition, clinical manifestations, diagnostic approach and management of this important condition.

SummaryObjective: To evaluate the usefulness of IgA antiphospholipid antibodies as markers of thrombosis and/or antiphospholipid antibody syndrome. Patients and Methods: A cross-sectional study design in a tertiary, university-based, autoimmune reference hospital. Seven-hundred ninety-five patients classified into five different groups – autoimmune diseases (255), deep vein thrombosis (153), transitory ischemic attacks (108), obstetric complications (196), infectious diseases (83) and controls (81) – were tested for IgA, IgG and IgM aPL, and lupus anticoagulant. Plasma and serum samples were drawn for detection of aPL using an internationally standardized ELISA method and LA was carried out using coagulometric assays. Results: True IgA aPL were found only in two patients with systemic lupus erythematosus; these patients were also positive to IgG aPL. Conclusion: The incidence of true positivity to IgA anticardiolipin antibodies is extremely low. Their determination was not helpful in diagnosing the antiphospholipid syndrome or in explaining thrombotic events or aPL related manifestations – fetal loss – in the groups studied.
