Semen May Harbor HIV Despite Effective HAART: Another Piece in the Puzzle

The risk of male-to-female intravaginal HIV-1 transmission is estimated at about 1 event per 200–2000 coital acts. The aim of this study was to assess the residual risk of HIV presence in semen in patients under HAART therapy.The study took place in France from October 2001 to March 2009. 394 paired blood and semen samples were provided from 332 HIV-1 infected men. The Roche Cobas AMPLICOR Monitor HIV assay was used to quantify HIV-1 RNA in blood and in seminal plasma. Three percent of 394 HIV-1 infected men enrolled in an assisted reproductive technology program harbored detectable HIV-1 RNA in semen, although they had no other sexually transmitted disease and their blood viral load was undetectable for at least 6 months under antiretroviral treatment.These data suggest that undetectable plasma HIV RNA means a lower risk of viral transmission through seminal fluid on a population level, but not necessarily at the level of the individual

Cost-Effectiveness Analysis of the Gonadotropin Treatments HP-hMG and rFSH for Assisted Reproductive Technology in France: A Markov Model Analysis

International audienceOBJECTIVES: The objectives of this study were to assess (1) the expected cost of a live birth (LB) after in vitro fertilization with two different gonadotropin treatments [high purified human menopausal gonadotropin (HP-hMG) and recombinant follicle-stimulating hormone (rFSH)] as the single cost variable, and (2) the cost effectiveness of HP-hMG relative to rFSH in the context of the routine practice of assisted reproductive technology (ART) in France. METHODS: A Markov model was developed to simulate the therapeutic management, the in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) courses, and the effects of complications in hypothetical cohorts of 30,000 patients undergoing IVF/ICSI with fresh embryo transfer (up to four attempts) using data from the MERIT and MEGASET clinical trials or from French routine ART practice. RESULTS: The cost per LB was estimated at \texteuro12,145 and at \texteuro14,247 with HP-hMG and rFSH, respectively, using efficacy data from published clinical trials. The resulting incremental cost-effectiveness ratio (ICER) was -~\texteuro11,616 per LB. HP-hMG was less expensive by around \texteuro15.0 million and more effective by 1289 additional LBs. Using French clinical data, the cost per LB was \texteuro16,415 and \texteuro18,7531 with HP-hMG and rFSH, respectively. The ICER for HP-hMG versus rFSH was estimated at -~\texteuro7,719 per LB with a saving of about \texteuro8.54 million and 1097 additional LBs. Deterministic sensitivity analyses showed that the main ICER drivers were the LB rate, followed by the total gonadotropin doses. The probabilistic sensitivity analysis indicated that HP-hMG was the dominant strategy in 71.2% of cases using the clinical trial data and in 50.2% of cases using the French data. CONCLUSION: This analysis indicates that compared with rFSH, HP-hMG is less costly for IVF/ICSI management from the French healthcare payer's viewpoint. The results of the present Markov model analysis are consistent with previous findings in other European countries

Added value of anti-Müllerian hormone serum concentration in assisted reproduction clinical practice using highly purified human menopausal gonadotropin (HP-hMG)

International audienceIntroduction: The individual response to controlled ovarian stimulation (COS) depends on several factors, including the initial dose of gonadotropin. In repeated in vitro fertilization (IVF) cycles, the initial dose of gonadotropin is mainly established on the basis of the previous attempts' outcomes. Conversely, in naive patients, the ovarian response should be estimated using other criteria, such as the serum concentration of anti-M€ ullerian hormone (AMH). However, in clinical practice, the initial gonadotropin dose is not systematically adapted to the AMH level, despite the known relationship between AMH and ovarian reserve. Material and Methods: French non-interventional, longitudinal, prospective, multicentre, cohort study that included infertile women who underwent COS with highly purified human menopausal gonadotropin (HP-hMG 600 IU/mL) during their first IVF/intracytoplasmic sperm injection (ICSI) cycle. Data were collected prospectively during routine follow-up visits from COS initiation to 10−11 weeks after embryo transfer. Results: Data from 235 of the 297 enrolled women were used for the study. Serum AMH level was negatively correlated with the initial and total HP-hMG doses (p<0.001), and positively correlated with the number of retrieved oocytes (p<0.007). Embryos were obtained for 94.0% of women, and fresh embryo transfer was performed in 72.8% of them. The clinical pregnancy rate was 28.5% after the first embryo transfer. Conclusion: Selecting the appropriate starting dose of gonadotropin is crucial to optimize the IVF/ICSI procedure. For the first attempt, the serum AMH level is a good biomarker to individualize treatment

Prospective multicenter observational real-world study to assess the use, efficacy and safety profile of follitropin delta during IVF/ICSI procedures (DELTA Study)

International audienceObjective: To describe the use, efficacy and safety profile of follitropin delta in women undergoing IVF/ICSI in routine clinical practice after one treatment cycle.Study design: This was a French multicenter, prospective, observational study conducted in 14 fertility centers between June 2020 and June 2021. During this period, 248 women undergoing IVF or ICSI were treated with follitropin delta for the first time. Women were followed up to 10-11 weeks after the first fresh or frozen embryo transfer. The main outcomes were use of dosing algorithm, follitropin delta dosing patterns, ovarian response, pregnancy, and adverse drug reactions in routine clinical practice.Results: The analyzable population consisted of 223 patients with mean ± SD age of 33.0 ± 4.4 years, body weight of 65.7 ± 11.8 kg, and the median (IQR) AMH level was 2.6 (1.5-4.0) ng/mL. For 193 patients (86.5 %) it was the first IVF/ICSI cycle and for 30 (13.5 %) the second. The algorithm was used for the calculation of the starting dose for 88.3 % of the patients. The mean daily starting dose of follitropin delta was 11.4 ± 4.1mcg for the whole analyzable population and 14.4 ± 5.2 mcg for the sub-group of 26 patients dosed without the algorithm. The mean duration of stimulation with follitropin delta was 10.8 ± 5.2 days. The mean total dose of follitropin delta administered was 122.2 ± 80.0 mcg. An antagonist protocol was used in 90.3 % of patients. The mean ± SD number of oocytes retrieved among patients that started stimulation was 11.3 ± 6.8 and 46.1 % of patients achieved the targeted response of the algorithm of 8-14 oocytes retrieved. A fresh transfer was performed for 77.6 % of patients; the mean ± SD number of embryos transferred was 1.3 ± 0.5. The implantation rate was 36.0 %. Per started cycle, clinical pregnancy was reported in 35.0 % of the patients and ongoing pregnancy in 29.6 %. In total, 5 patients (2.2 %) reported an event of OHSS.Conclusion: Clinical results as collected in routine clinical practice are promising, showing a favorable effectiveness-safety profile of follitropin delta for a very varied patient population (including anovulatory PCOS, very poor responders, or non-IVF naïve patients). These real-world data complement results from clinical trials and provide useful information for usual clinical practice within a heterogeneous population group
