ABSTRACT

Neurosyphilis follows a more aggressive and different clinical course in HIV-infected patients compared to patients with normal immunity. Two historical series of patients with a diagnosis of neurosyphilis between 1995 and 2008 were compared: they included a group of 15 patients with y and 28 patients without HIV infection. Probability of neurosyphilis in patients with positive serum VDRL was increased in patients infected with HIV comparedto HIV negative patients (OR: 62.37 IC:95 percent (32.1-119.1) p value:< 0,001). Predominant clinical manifestations in neurosyphilis in the HIV negative group were ocular abnormality, vascular encephalic and spinal cord lesions. In the HIV positive group, they were fever, ocular abnormalities and headache. There were no differences in cerebrospinal fluid characteristics between both groups. Neurosyphilis was diagnosed even in patients with blood VDRL of < 1:32, that happened in 17.8 percent of the HIV positive patients with blood and in 60 percent of t he HIV negative patients. Penicillin sodium given at dose ¡Ý than 18.000.000 IU/day IV during 14 days was the most common treatment. In patients with clinical neurosyphilis, 93 percent of HIV negative group, and 54.2 percent of HIV positive group had persistent neurological after-effects. Three HIV positive patients died due to causes not related to neurosyphilis.

ABSTRACT

La sífilis congénita es un problema relevante en nuestro país. Actualmente no existen exámenes de uso rutinario que permitan confirmar su diagnóstico. En este estudio prospectivo multicéntrico se evaluaron 60 binomios madre-RN que presentaban test no treponémicos (TNT) reactivos. En todas las muestras se realizaron 2 TNT (VDRL y RPR) y 7 test treponémicos (TT): dos evaluaban IgM, uno IgG y cuatro IgM + IgG. La concordancia entre los tests que evaluaban IgG o IgG + IgM fue de 90 por ciento y entre los que evaluaban IgM fue de 87,5 por ciento. Un resultado IgG positivo se observó en 100 por ciento de los binomios cuyas madres presentaron sífilis durante el embarazo o portaban serología residual. La IgM fue positiva en 64 por ciento de las madres con sífilis adecuadamente tratada durante el embarazo, siendo sus neonatos todos IgM negativa. Aquellas madres con un tratamiento inadecuado tuvieron IgM positiva en 82.3 por ciento y sus RN tuvieron IgM positivas en 11,8 por ciento. En conclusión, la IgM materna no aporta al diagnóstico de sífilis congénita, pues su positividad no se correlaciona con el riesgo de que el RN presente este cuadro. La Igm en el RN es útil para el diagnóstico precoz de sífilis congénita, pero su ausencia no descarta esta patología
