Unique Identifier : AIDSLINE ICA10/94371393 AB OBJECTIVES: antiphospholipid antibodies (AP) appear in patients (pts) with autoimmune disorder, such as systemic lupus erithematosus and HIV1 infection. The aim of our study is to investigate the presence of APS in HIV1 positive pts with ARC or AIDS and correlation between them and the clinical pictures. MATERIALS AND METHODS: 14 AIDS (CDC 4 C1) and 5 ARC (CDC 4 C2) showed some clinical and laboratoristic criteria for the identification of APS; the evaluation of the AP was performed by IgG-IgM Elisa, VDRL, lupus anticoagulant activity (LAC), antibody anti platelets. RESULTS: 19/19 pts (AIDS and ARC) had fever, headache (7 pts), paresis (7), cranial nerve involvement (3), Raynaud S. (2), deep vein and arterial trombosis (2), disseminated intravascular coagulation (2), encephalitis (1). The concomitant infections were cytomegalovirus dissemination (6) and MAC infection (4). All pts were positive to IgG or IgM while VDRL and LAC were positive only in 5/18. Tc and magnetic resonance of the brain were positive in 1 pt with neurological symptoms. Corticosteroid and anticoagulant therapy improved the clinical picture with disappearance of fever (19/19), partial or total resolution of neurological and vascular injures. CONCLUSIONS: 1) The APS emerges especially in advanced stage of HIV1 infection. 2) The neurological and vascular symptoms are the most common findings. 3) the absence of evident brain lesions, except in one pt, is usual. 4) The symptoms associated to platelet number reduction and PTT alteration are the guide towards the APS diagnosis.
