50 Diagnosis Anti-phospholipid syndrome with ITP
Pulmonary embolism and DVT Immune thrombocytopenia Anti-phospholipid syndrome with ITP

51 Revised Classification Criteria for the Antiphospholipid Syndrome
At least one of the Clinical criteria At least one of the Laboratory criteria Miyakis S, J Thromb Haemost 2006; 4: 295–306.

52 Clinical Criteria Vascular thrombosis Pregnancy morbidity
arterial, venous, or small vessel thrombosis, in any tissue or organ For histopathologic confirmation, thrombosis should be present without significant evidence of inflammation in the vessel wall Pregnancy morbidity Miyakis S, J Thromb Haemost 2006; 4: 295–306.

53 Clinical Criteria Vascular thrombosis Pregnancy morbidity
>1 unexplained fetal death (GA >10 wk) >1 premature birth (GA <34 wk) due to (i) eclampsia or severe preeclampsia or (ii) placental insufficiency >3 unexplained consecutive spontaneous Abortions (GA <10 wk) Miyakis S, J Thromb Haemost 2006; 4: 295–306.

54 Laboratory criteria**
Anticardiolipin (aCL) antibody : IgG and/or IgM in medium or high titer (i.e. >40 GPL or MPL, or >99th percentile) Anti-2 glycoprotein-I antibody : IgG and/or IgM (>99th percentile) ** > 2 occasions at least 12 wk. apart Miyakis S, J Thromb Haemost 2006;4:295–306.

55 LA correlates better with thrombosis than aCL
Giannakopoulos B, et al. Blood 2009;113:985-94

56 Features associated with APS (non-criteria features of APS)
Heart valve disease Livedo reticularis Thrombocytopenia Nephropathy Neurological manifestation IgA aCL IgA anti-2 glycoprotein-I Antiphosphatidylserine Ab Antiphosphatidylethanolamine Ab Ab against prothrombin alone Ab against phosphatidylserine/prothrombin complex - MR/MS/AR/AS; Valve thickness >3 mm, Localized thickening involving the leaflet’s proximal or middle portion, Irregular nodules on the atrial face of the edge of the mitral valve, and/or the vascular face of the aortic valve. - In unselected APS patients, LR has been retrospectively correlated with aCL and arterial thrombosis, but not with anti-b2GPI or LA, venous thrombosis, or pregnancy morbidity - The committee consented that thrombocytopenia occurring in patients with persistent aPL, in the absence of clinical manifestations of APS, should be considered to be different from ITP: such patients have an increased thrombotic risk and require closer follow-up. - Thrombotic microangiopathy involving both arterioles and glomerular capillaries; Fibrous intimal hyperplasia involving organized thrombi with or without recanalization, Fibrous and/or fibrocellular occlusions of arteries and arterioles, Focal cortical atrophy, Tubular thyroidization (large zones of atrophic tubules containing eosinophilic casts) - In one small study of APS patients without SLE, long-term presence of LA is a risk factor for dementia (Evidence Level II). In SLE patients, persistent elevation of aPL is associated with cognitive dysfunction (Evidence Level I). Transverse myelopathy (TM) is a rare entity within APS. Limited data suggest that in the 1% of SLE patients who manifest TM, the latter is associated with aPL (Evidence Level IV) The IgA aCL are usually detected together with either IgG and/or IgM isotypes in patients with APS. In patients with collagen disease, IgA aCL associates with thrombocytopenia, skin ulcers and vasculitis, indicating a patient subgroup at risk for specific clinical manifestations (Evidence Level III), and it is highly prevalent in African–American SLE patients. IgA anti-b2GPI are the most frequently detected antibodies in patients in specific ethnic groups. A systematic review on antiprothrombin antibodies and risk of thrombosis in APS failed to reveal an association, irrespective of isotype, site and type of event, or presence of SLE. Both the sensitivity and specificity of aPS/PT are higher than those for aPT-A, whereas 95% of patients with aPS/PT are also LA positive, suggesting that aPS/PT can also serve as a confirmatory assay for LA (Evidence Level II); these results, however, only come from one study [128], and concerns regarding aPS/PT arise from multivalent antibody binding; the possibility of measuring antibodies against non-complexed phospholipids present in the sample needs to be excluded. Miyakis S, J Thromb Haemost 2006;4:295–306.

58 Detection of Lupus Anticoagulant Antibodies by in Vitro Coagulation Assays
The intrinsic coagulation pathway is initiated by contact activation on glass, silica, or kaolin (as in the activated partial-thromboplastin time [APTT], colloidal-silica clotting time [CSCT], and kaolin clotting time [KCT] assays), whereas the extrinsic coagulation pathway is initiated by the formation of a complex between tissue factor (TF) and factor VIIa (as in the dilute prothrombin time [dPT] assay). Russell’s viper venom directly activates factor X. Taipan, Textarin, and Ecarin snake-venom extracts directly activate prothrombin but have different cofactor requirements. Taipan venom activation of prothrombin requires phospholipid and calcium but not factor Va. Textarin activation of prothrombin requires phospholipid, calcium, and factor Va, whereas Ecarin activation of prothrombin is independent of cofactors and does not require phospholipid, calcium, or factor Va. Levine JS. NEJM 2002;346:

59 Lupus Anticoagulant Test
Step 1 : Screening – Prolongation of coagulation in at least one phospholipid-dependent in vitro coagulation assay with the use of platelet-poor plasma Step 2 : Mixing study with normal pooled plasma – failure to correct the prolonged coagulation time Step 3 : Confirmation by shortening or correction of the prolonged coagulation time after the addition of excess phospholipid or platelets that have been frozen and then thawed Step 4 : Ruling out other coagulopathies with the use of specific factor assays if the confirmatory test is negative or if a specific factor inhibitor is suspected

60 LA1 / LA2 Ratio = Screening / Confirm Ratio ( a/c : b/d )
Fig. 2. Clotting times obtained with an LA positive test plasma or normal plasma (NP) with a low PL concentration (screening test) and a high PL concentration (confirmatory procedure). The PL concentration used in the ‘‘usual’’ APTT is indicated. The Lupus Ratio (a/b:c/d) is mathematically identical with the screening/confirm ratio (a/c:b/d).

61 Lupus Anticoagulant False positive False negative
Heparin contamination Specific anticoagulation factor antibody False negative Improper plasma preparation – platelet contamination = phospholipid Diluting effect of mixing studies – weak LA
