oportunistic infections in HIV

D Salemović, Dj Jevtović, B Brmbolić, J Ranin, M Tucaković
The primary causes of morbidity and mortality in persons infected with the human immunodoficiency virus are oportunistic infections. Infection with the human immunodeficiency virus (HIV) induces progressive quantitative and qualitative defects in CD4 (T helper) lymphocytes. Macrophage and monocyte function may also be impaired as a result of HIV infection. Consequently, patients in the later stages of HIV infection (ARC and AIDS) frequently experiency infections against which either cellular od humoral immunity, or both, are important...

Movement disorders are not common in acquired immunodeficiency syndrome. Hemichorea-hemiballism (HC-HB) is the most common of them all, and it is usually related to oportunistic toxoplasmosis of the basal ganglia. We present a 28-year-old man, HIV positive with HC-HB caused by a right subthalamic granuloma, which did not respond to treatment for toxoplasmosis. Cryptoccococic antigen was positive in the cerebrospinal fluid and antifungic therapy led to clinical and radiologic improvement, thus the diagnosis of a granulomatous lesion by Cryptococcus neoformans was established...

A 50-year-old man with positive test for human immunodeficiency virus (HIV) by enzyme-linked-immunoassy and Western-blot, without clinical manifestations of acquired immunodeficiency syndrome (AIDS), developed acute polyradiculoneuritis and was treated by plasmapheresis with improvement. We believe that chemical homologies of antigenic determinants between HIV and P2 protein of peripheral nervous system and myelin basic protein may induce crossed-reaction, thus developing acute polyradiculoneuritis and central nervous system involvement, respectively...
