Comparisons of the different studies analysing the signification of aPZ-Ab on the thrombotic risk
References | Controls (n) | Cut-off (AU/mL) | Patients | Conclusions |
---|---|---|---|---|
[18] | 82 donors from the blood bank | 1 (for IgG or IgM)* | 50 with arterial thrombosis, 64 with venous thrombosis | aPZ-Ab (IgG) higher in patients with arterial thrombosis, but the vast majority < 1 AU/mL |
[19] | 33 healthy volunteers | IgG: 75th pctl: 4.4 IgM: 75th pctl: 5.3 | 102 patients with lupus anticoagulant (LAC; 62 with thrombosis, 33 asymptomatic) | IgM > 75th pctl more frequent in the patient group. Similar frequency of elevated aPZ-Ab (IgG or IgM) in patients with and without thrombosis |
[20] | 59 healthy volunteers | IgG: 95th pctl: 10 IgM: 95th pctl: 10 | 86 consecutive patients with anticardiolipin (aCL) antibodies | Frequency aPZ-Ab in the patient group: 40.7% The frequency of aPZ-Ab increases in patients with a double or triple positivity of antiphospholipid antibodies Higher frequency of aPZ-Ab in patients with LAC (57.7%) than in patients without LAC (25.6%) Similar frequency of elevated aPZ-Ab (IgG or IgM) in patients with and without thrombosis High frequency of aPZ-Ab in patients with foetal loss |
[21] | 23 healthy volunteers | NR | 21 with central retinal vein occlusion | No significant difference in the frequency of aPZ-Ab between patients and cases |
*: whereas all the studies used the same commercial assay, this one used a homemade assay. NR: not-reported
