Lipid profile during pregnancy in HIV-infected women

Purpose: We investigated the evolution of serum lipid levels in HIV-infected pregnant women and the potential effect of antiretroviral treatment during pregnancy using data from a national surveillance study. Method: Fasting lipid measurements collected during routine care in pregnancy were used, analyzing longitudinal changes and differences in lipid values at each trimester by protease inhibitors (Pls) and stavudine use. Multivariate analyses were used to control for simultaneous factors potentially leading to hyperlipidemia. Study population included 248 women. Results: Lipid values increased progressively and significantly during pregnancy: mean increases between the first and third trimesters were 141.6 mg/dL for triglycerides (p <.001), 60.8 mg/dL for total cholesterol (p <.001), 13.7 mg/dL for HDL cholesterol (p <.001), and 17.8 mg/dL for LDL cholesterol (p =.001). At all trimesters, women on PIs had significantly higher triglyceride values compared to women not on Pis. The effect of Pls on cholesterol levels was less consistent. Stavudine showed a dyslipidemic effect at first trimester only. Multivariate analyses confirmed these observations and suggested a potential role of other cofactors in the development of hyperlipidemia during pregnancy. Conclusion: The changes observed point to the need to further explore the causes and the clinical correlates of hyperlipidemia during pregnancy in women with HIV

Combined use of goserelin acetate and human menopausal gonadotropin in the induction of follicular growth in a program of fertilization in vitro and embryo transfer

OBJECTIVE: to investigate the efficacy of a gonadotropin-releasing hormone analogue (GN-RH-a) in combination with human menopausal menotropin (hMG) for in-vitro fertilization. METHODS: 30 infertile women aged 32 to 37 years received a combined treatment with a long-acting slow-releasing Gn-RH-a and hMG to perform ovarian stimulation in a program of in-vitro fertilization. Serum levels of Follicle Stimulating Hormone (FSH), Luteinizing Hormone (LH), 17-beta-estradiol (E2), Progesterone (P), were evaluated and transvaginal ultrasonographic examinations were performed during the treatment to assess the ovarian volume, the mean number and diameter of growing follicles and the endometrial morphology and thickness. Oocyte retrieval was performed by transvaginal-ultrasound-guided approach, 24-36 hours after the administration of human chorionic gonadotropin (hCG). RESULTS: our data suggest that the combined use of Gn-RH-a and exogenous gonadotropins is associated with a more uniform ovarian response and with the absence of premature LH discharge. Moreover, the Gn-RH-a as polymer implant provides a controlled delivery per day over a one-month period and avoids the inconvenience of a daily administration. CONCLUSIONS: this kind of Gn-RH-a formulation, in in-vitro fertilization programs, appears very effective in inducing a reversible hypogonadic state, easy to manage and well tolerated by the patient. Its association with exogenous gonadotropins appears to be effective in increasing the success rate of good quality oocyte retrieva

Antiretroviral therapy at conception in pregnant women with HIV in Italy: Wide range of variability and frequent exposure to contraindicated drugs

Methods: Data from a large national surveillance study was used to describe antiretroviral regimens in pregnant women with HIV, with particular reference to the presence at conception of antiretroviral treatments contraindicated in pregnancy. Therapeutic changes during pregnancy were also analysed. Results: Among 334 women on antiretroviral treatment at conception, less than half (42.4%) reported current pregnancy as planned. A large number of different regimens (80) was observed. All the regimens included at least one nucleoside or nucleotide reverse transcriptase inhibitor. Non-nucleoside reverse transcriptase inhibitors and protease inhibitors were present in similar proportions (39.2% and 40.7%, respectively). The most commonly used drugs were lamivudine (83.2% of regimens), zidovudine (50.0%), stavudine (d4T; 38.0%), nevirapine (25.7%), didanosine (ddl; 17.7%) and nelfinavir (17.7%). Treament with efavirenz (13.5% of regimens) and ddI+d4T (9.6%) was markedly frequent. Use of efavirenz at conception was associated with a subsequent treatment change during pregnancy (odds ratio [OR]: 13.2.; 95% confidence interval [CI]: 3.2-53.8, P < 0.001). A similar but less strong association was found for ddI (OR: 1.8; 95% CI: 1.03-3.25, P=0.033), whereas being on nevirapine was associated with a lower risk (OR: 0.58; 95% CI: 0.38-0.81, P=0.013). Conclusions: Our data show that treatment at conception frequently represents the regimen previously selected for the treatment of the non-pregnant woman. The observed rates of exposure to contraindicated treatment should lead prescribing physicians to consider in HIV-positive women therapeutic choices that take into account the likelihood of an unplanned pregnancy. Such an approach is likely to reduce not only unintended exposures to contraindicated drugs, but also therapeutic changes during pregnancy
