Prognostic value of autoantibodies against erythrocytes and platelets in chronic lymphocytic leukemia (CLL).

Antiglobulin test (AT) and Dixon tests were performed in 100 patients with CLL. Thirty-five of them had Rai stages 0 or 1, 19 stage 2, 13 stage 3, and 33 stage 4. Twelve patients showed red blood cells autoantibodies (RBCAb) positivity; positivity at Dixon test (direct, indirect, or both) was observed in 74%. The presence of autoantibodies against erythrocytes and platelets did not influence survival curves, but anemia and thrombocytopenia are considered risk factors, independently of the presence of an autoimmune disorder. Nine RBCAb positive patients with positive Dixon test had the worst survival curves, 5 of these were anemic and 1 thrombocytopenic and anemic.

CT evaluation in patients with transient ischemic attack. Correlation between clinical and angiographic findings.

35 patients clinically diagnosed with transient ischemic attack (TIA) and 15 patients clinically diagnosed with reversible ischemic neurological deficits (RIND) were examined by computerized tomography (CT). 34% of TIA patients showed positive CT scans consisting of small hypodenase areas: 60% of RIND patients had larger lesions. In 20% of the overall group the only pathological finding consisted of unilateral focal atophy or ventricular asymmetry. Correlation between angiographically demonstrated atherosclerotic lesions and positive CT was high. On the contrary, no correlation was found between either the risk factors or the natural history of ischemic attack and positive CT findings.
