Unique Identifier : AIDSLINE ICA10/94369649 AB OBJECTIVE: It was the aim of our study to detect whether or not the lesion of the ascending central and peripheral sensory tracts in HIV-infected patients are progressive. METHODS: 36 patients (mean age 35.4 +/- 4.6 years, HIV-infection since 5.6 +/- 1.8 years (laboratory diagnosis), 9 female, 27 male) were examined clinically and by somatosensory evoked potentials of the median (MN) and tibial nerve (TN) in conventional manner (10/20 system). Investigations were repeated first 15 +/- 4 months later and second 29 +/- 6 months later. RESULTS: Clinical investigations showed an increase of findings indicating progressive lesion of sensory tracts (diminution of vibration, hypesthesia, ataxia). Neurophysiological investigations showed a statistical significant exponential increase (Friedman Nonparametric Repeated Measures Test) for latencies of evoked potentials (MN: N13, N19, N19-N13; TN: N21, P40, P40-N21). CONCLUSION: HIV-infection induces an exponential progressive degeneration of the peripheral and central ascending sensory pathways. These alterations cause a deterioration of quality of life in HIV-infected patients. It is assumed that the progressive lesion is of polyaetiologic nature. Besides indirectly promoted demyelination by HI-Virus, metabolic disturbances and neurotoxic factors like cytokines and deleterious viral products had to be discussed.
