RESUMEN
The re-emergence of syphilis among HIV-infected patients has been reported in recent years. We evaluated co-infection among heterosexual immigrants in an Israeli AIDS center. The records of 1060 HIV-infected patients were evaluated for positive syphilis serology between the years 2000 and 2005, and all seropositive patients were further evaluated. We found 150 HIV/syphilis co-infected patients (57% men, 93% of African origin), of who 135 were found to have late latent syphilis. Lumbar puncture (LP) was performed in 51 patients, 16 (31%) had abnormal cerebrospinal fluid (CSF) compatible with neurosyphilis. Abnormal CSF correlated with the absence of previous anti-syphilis treatment, but not with CD4 count, viral load or Venereal Disease Research Laboratory titres. Penicillin was recommended to all patients according to their disease stages and 81 patients completed 12 months post-treatment follow-up. Twenty-one of 81 (26%) treatments were successful, 33 (41%) showed 'serofast reaction' and 27 (33%) failed therapy. In conclusion, a high incidence of syphilis with CSF reactivity suggestive of neurosyphilis was observed in heterosexual Ethiopian HIV-infected patients. Thus, repeated serological screening and CSF evaluation seems to be indicated in these patients. Penicillin therapy resulted in 'serofast reaction' or treatment failure for most patients. More, intensive treatment might be needed for HIV/syphilis in co-infected patients, especially those with severe immune-deficiency and prolonged syphilis infection.

The objective of the study was to investigate the HIV-mother-to-child transmission (MTCT) rate in Israel. This was a retrospective study of HIV-infected pregnant women, mainly immigrants from Ethiopia, in six Israeli AIDS centres, in 2000-2005. Medical records of mothers and newborns were evaluated for HIV status, treatment and MTCT rates. Three hundred pregnancies of 241 HIV-infected women, resulting in 304 live births, were studied. In 86/241(36%) women, HIV diagnosis was made during the current pregnancy or shortly after labour. Thirty others were diagnosed during previous pregnancies. Highly active antiretroviral therapy (HAART) was prescribed in 76% of pregnancies. The mean viral load before labour was 23,000 +/- 100,000 copies/mL with a mean CD4 of 406 +/- 223 (range 4-1277) cells/mm(3). Caesarian sections were preformed in 175/300 pregnancies (103/175 with viral load <1000 copies/mL). During labour, azidothymidine (AZT) was given to 80% and nevirapine to 8% of the women. Eighty-eight percent of the neonates received AZT for six weeks. The overall HIV-MTCT rate was 3.6%. MTCT correlated significantly with delayed HIV diagnosis, low CD4, lack of HAART during pregnancy and lack of perinatal treatment. HIV treatment of mothers and their newborns throughout pregnancy, labour and perinatal period are crucial for effective prevention of MTCT, emphasizing the need for early HIV screening, diagnosis and treatment.
