, , , , To evaluate the seroprevalence of positive markers for syphilis, human immunodeficiency virus (HIV) I and II, human T cell lymphotropic virus (HTLV) I and II, and hepatitis B and C among women undergoing in vitro fertilization (IVF).
We conducted a retrospective analysis among patients who underwent IVF, between January 2013 and February 2016, and who had complete screening records.
We analyzed 1,008 patients who underwent IVF, amounting to 2,445 cycles. Two patients (0.2%) tested positive for HIV I and II and none for HTLV I and II. Three patients (0.3%) had positive screening for syphilis, and two (0.2%) had positive hepatitis C antibody test (anti-HCV). A positive hepatitis B virus surface antigen (HbsAg) test was observed in 4 patients (0.4%), while 47 (4.7%) patients were positive for IgG antibody to hepatitis B core antigen (anti-HbC IgG), and only 1 (0.1%) was positive for IgM antibody to hepatitis B core antigen (anti-HbC IgM). The anti-HbS test was negative in 659 patients (65.3%). Only 34.7% of the patients had immunity against the Hepatitis B virus. Patients with an anti-HbS negative result were older than those with a hepatitis B test (anti-HbS) positive result (36.3 versus 34.9; p<0.001).
The present study showed lower infection rates than the Brazilian ones for the diseases studied in patients undergoing IVF. Only a few patients were immunized against hepatitis B.

PURPOSE: To ascertain the seroprevalence of human immunodeficiency virus (HIV), hepatitis B (HBV), toxoplasmosis and rubella infections in pregnant women in northwestern Paraná. METHODS: We conducted a retrospective study based on the results of serological screening during prenatal care of 1,534 patients during the first half of 2010. We included only results from the first prenatal exam and with a simultaneous search for IgG and IgM antibodies to rubella and toxoplasmosis. Serology was performed by microparticle enzyme immunoassay (MEIA). Data were analyzed statistically by the χ² test, with the level of significance set at 5%. RESULTS: HIV positivity was 0.3%, positivity of HBV serology (HbsAg) was 0.5%, reactivity to IgM antibodies to Toxoplasma gondii was 1.1%, and reactivity to IgG antibodies was 59.0%. For rubella, no patient was positive for IgM, and IgG reactivity was 99.6%. Data analysis showed no statistical association between seroprevalence and patient age, except for the frequency of anti-T. gondii IgG, which was higher in the 30 to 44 year age group. CONCLUSION: The prevalence of these infectious diseases in pregnant women from northwestern Paraná is comparable to that observed in other regions of Brazil.

PURPOSE: to estimate the prevalence of the hepatitis B surface antigen (HBsAg) in parturients admitted to the "Instituto Materno-Infantil de Pernambuco (IMIP)", Recife-PE, and to determine the serologic profile of the positive ones. METHODS: this is a prospective cross-sectional study where the VIDAS and VIDAS HBs systems were used for detection and confirmation of HBsAg, respectively. The parturients were randomly selected. In HBsAg+ patients, the other serologic markers were tested by the use of the AxSYM automated system. The newborn babies of HBsAg+ mothers were vaccinated with the Engerix B vaccine. RESULTS: among 1584 parturients, there were 9 (0.6%) HBsAg positive. None of them had anti-HBc IgM, thus they were all prevalent cases. In 1/9 (11.1%) of the HBsAg+ mothers, HBeAg was isolated and in 4/9 (44.4%), this antigen circulated along with its antibody, hence the importance of establishing the different magnitudes of risk of vertical transmission. Except for two newborn babies from a twin pregnancy (one with low birth weight), all presented seroconversion to anti-HBs with 3 doses of the vaccine. The premature twin babies showed seroconvertion only after the fourth dose of the vaccine. CONCLUSIONS: the prevalence of hepatitis B among parturients at IMIP is relatively low and all patients diagnosed had the chronic form of the infection.
