PURPOSE: to evaluate the attitudes and knowledge of obstetricians from public maternities in Salvador city (PMS) about the recommendations from the Health Ministry (HM) for the prophylaxis of vertical transmission of HIV (VTH) and antiretroviral therapy in pregnant women. The influence of working conditions, availability for quick testing and antiretroviral therapy has also been evaluated concerning the application of these recommendations. METHODOLOGY: a transversal study from August to November 2005, involving 129/152 (85%) of the obstetricians from all the PMS. The instrument used was a structured and self-explanatory anonymous questionnaire, with questions on the population characteristics, working conditions and availability of material, knowledge and attitudes related to HIV counseling and testing, and proceedings with the patients (use of AZT, recognition of risk factors, choice and management of type of delivery and puerperal care). RESULTS: 69% of the obstetricians stated they knew integrally the HM recommendations, 90.7% agreed with the compulsory request of quick testing for HIV; 63.6% chose the caesarean section as the type of delivery; 38% were against normal delivery; 37.5% recommended isolation of positive serum patients and 58.1% indicated tubal ligation. Most of them (90%) mentioned the existence of factors unfavorable to the recommendations applicability, and among those factors, the most pointed were the inadequate way the pre-natal admission was done and the lack of information at that occasion. Even though the quick testing was available, only one third of the interviewees stated that the result was always available in due time. CONCLUSIONS: some attitudes related to the assistance to the pregnant women with HIV were incompatible with the HM recommendations. According to the interviewees, the inadequacy of the pre-natal plus the non-availability of quick testing, influence negatively the applicability of VTH prophylaxis recommendations.

PURPOSE: to describe the genetic diversity of HIV-1 isolates from serum positive women followed up at a reference center. METHODS: transversal study, including 96 women with two ELISA serological tests and a Western Blot confirmatory test. The viral charge was determined by the b-DNA kit, and the counting of T CD4 and T CD8 lymphocytes, by the Excalibur flow cytometry, from the samples of peripheral blood. The extraction and purification of pro-viral DNA was performed by the polymerase (PCR) chain reaction, using the QIAamp Blood kit (Qiagen Inc., Chatsworth, CA, U.S.A.). Sequencing of the pol region was done in 52 isolates with the 3100 Genetic Analyzer (Applied Biosystems Inc., Foster City, CA), and the genotyping was assessed by the Rega Subtyping Tool. The resistance pattern to anti-retrovirals (ARV) was inferred by the algorithm from the Stanford HIV Resistance data bank. Participants' clinical stages were defined as A, B or C, according to the criteria established by the Center for Diseases Control (CDC). For statistical analysis, the χ2 test was used for the categorical variables and the Student's t test, for the numerical variables. RESULTS: The average age of the sample, the disease and treatment average duration were respectively: 33.7 years old, 3.8 and 2.5 years. The viral charge average was log10 2.3 copies/mL; the T CD4 e T CD8 lymphocytes, 494.9 cells/µL and 1126.4 cells/µL. Concerning the clinical stage, 30 women were in stage A, 47 in B and 19 in C. Sequencing from the 52 isolates found 33 of B subtype, 4 of F, 1 of C and 14 of BF recombinant. The analysis of resistance to ARV has shown 39 (75.0%) susceptible isolates, 13 (25.0%) resistant to reversal transcriptase inhibitors (RTIN), and 3 (5.7%) resistant to protease inhibitor (PI). CONCLUSIONS: There has been a large variety of HIV-1 and a high percentage of isolates resistant to ARV in the studied sample.
