[Cerebrovascular disease as a form of presentation of HIV infection].
Several necropsy reports have suggested that cerebral vascular disease (CVD) is more frequent in HIV positive patients than in HIV negative individuals of the same age, although clinical signs are rare. We describe three patients for whom CVD was the clinical manifestation that led to diagnoses of HIV infection. The patients were two men and a woman aged 29, 52 and 66, respectively, with differing risk factors for CVD: smoking (3), blood hypertension (2), endocarditis (1) and free protein S deficiency (1). The risk factors for HIV infection were also different. The CVD diagnoses were confirmed by computed tomography, which revealed lacunar infarction in two cases with favorable outcomes and embolia-like infarction with subarachnoid hemorrhage in the third patient, who died a few days later. CD4 levels varied (50, 130 and 689/mm3). Our observations lead us to the following conclusions: 1) CVD can be a first clinical manifestation of HIV infection and the disease that allows seropositivity to be diagnosed. Although CVD usually presents in advanced stages of HIV infection, it can also occur in seropositive patients who do not meet the criteria for AIDS. 2) The classical risk factors for vascular disease probably play a dominant role in the etiology of CVD in such patients, alongside systemic complications related to the virus; the direct role of HIV remains to be determined. 3) AIDS should be considered and ruled out in patients with CVD who are at risk for HIV infection, even in older patients with vascular risk factors.
