Main purpose of this study was to evaluate vestibular function,focusing attention on percentage of peripheral damagein 30 HIV positive patients (23 male, 7 female), age range26-68 years, belonging to Categories A-C of CDC classificationof infection, underwent electronystagmographywith bithermic stimulation according to Freyss (125 cc ofwater at 30 °C and 44 °C in 30 sec). The angular velocityof slow phase was considered as the main value oflabirinthine functionality. Peripheral vestibular damage hasbeen found in 35.7% of Class A patients; a similarpercentage of peripheral signs was found in Classes B andC, where, on the contrary, increased central vestibular signswere observed. In order to evaluate equilibrium in thesepatients, a Dynamic Gait Index (DGI) test was performed.Scores were > 21 points in 85.7% of Class A patients anddecreased in Classes B and C.
Scopo del lavoro è valutare in quale percentuale di pazienti HIVpositivi esistano segni strumentali di danno vestibolare perifericoed eventuale interessamento delle vie vestibolari centrali; aquesto scopo 30 pazienti sieropositivi (23 uomini e 7 donne), dietà compresa tra 26 e 68 anni, in Categoria A, B e C di infezionesecondo la classificazione CDC sono stati sottoposti ad esameElettronistagmografico con stimolazione termica secondoFreyss (125 cc. di acqua a 30 °C e 44 °C in 30 secondi). È statavalutata la VAFL (velocità angolare della fase lenta) come parametrodi funzionalità labirintica. Il 35,7% dei pazienti in classeA presentava segni di sofferenza vestibolare periferica; nelleclassi B e C tale percentuale resta costante ma aumentano i segniclinici di sofferenza vestibolare centrale. L’equilibrio è statovalutato utilizzando il Dynamic gait index (DGI) test. Il punteggiodel test è correlabile allo stadio dell’infezione; l’85,7Þi pazienti in classe A hanno ottenuto punteggi superiori a 21,mentre il 40% in classe C inferiori a 19
