title: [Pregnancy and HIV infection: the need for routine serological evaluation].
abstract: OBJECTIVE
  To determine the frequency of pregnancies among HIV-infected women in a sanitary area. To evaluate the proportion of women not receiving anti-retroviral treatment to decrease vertical transmission and the reasons why this treatment was not administered.
  
  
  METHODS
  Point prevalence study performed on all women followed for 1997 at the HIV Infection Unit in a 360-bed hospital. The following variables were obtained: social class, civil status and place of residence, risk factors for HIV infection, obstetric antecedents (pregnancies, number of term pregnancies, living newborns) as well as prescription or not of anti-retroviral therapy during pregnancy.
  
  
  RESULTS
  Out of 85 women included in the study, 51 (60%) reported to have had a pregnancy and 17 of these (33%) had interrupted the pregnancy at some time. No significant differences were found between pregnancy or abortion and the analyzed socio-demographic variables or risk factors for HIV infection. Only 12% of women with a full length pregnancy received anti-retroviral therapy. Of women with term pregnancy who were not treated, most (63%) did not know they were infected before delivery and an additional 10% refused therapy. Forty-four percent of women with children continued with pregnancy despite knowing they were infected. Vertical transmission occurred in a 13% of cases in which no therapy was instituted and in no case in which zidovudine was administered during pregnancy.
  
  
  CONCLUSIONS
  The frequency of pregnancies among HIV-infected women is high in our area and a substantial number of women do not know they are infected. These data support the serological study to HIV in all pregnant women and the necessity of a higher level of information in order that the seropositive women be aware of the responsibility she takes when she decides to go on with her pregnancy.
