Filter by:The aim of this study is to evaluate the effect of zinc gluconate and/or selenium yeast supplementation during six months on clinical (glucose, cholesterol, triglycerides, bone mineral density and body composition) and immunological (oxidative stress, CD4+ count and pro-inflammatory cytokines) parameters in a population with HIV diagnosis on antiretroviral treatment.
There is not yet a standardized system of human embryonic culture in vitro. In addition, technical improvements continually appear. The investigators recently carried out a study in which it shows that the grouped embryo culture at low oxygen tension (5% O2) in a benchtop incubator shows better success rates than individual culture at atmospheric oxygen tension (20% O2) in a conventional incubator. For these reasons, the investigators have decided to continue this research line to evaluate the efficacy of a new ART station with a closed environment in comparison of an open flow cabinet. This new system keeps a controled environment maintaining a carbon dioxide (CO2) concentration of 6% and a temperature of 37 degrees. A prospective randomized study will be carried out in which the manipulation of the gametes and pre-embryos of the patients will be carried out in open laminar flow cabinets or in a closed station that maintain the CO2 and temperature conditions.
Subfertility is the inability to conceive after 12 months of regular unprotected sexual intercourse. Around 15% of couples suffer from subfertility. As a treatment for subfertility, Assisted Reproductive Techniques (ART) have been a choice for subfertile couples. In Egypt in 2010, Pregnancy Rate was calculated to be 36.2%, Live Birth Rate to be 25.7%. Implantation is the process by which the embryo adheres to the wall of the uterus. Endometrial receptivity plays the most important role for successful implantation after embryo quality. It is estimated that up to 70% of early pregnancy losses are due to failure of implantation. Despite extensive research, the embryo-maternal dialogue that orchestrates the implantation process is still not fully understood. Much effort has been done in the last decades to detect factors affecting Implantation and improve endometrial receptivity. Human Chorionic Gonadotropin (hCG) is a placental glycoprotein hormone that required to maintain pregnancy. Recent research data demonstrates that hCG is secreted very early by the embryo before implantation to facilitate it. hCG has been proved to cause attraction of inflammatory cells, promote angiogenesis, regulate chemical mediators at the endometrium. These effects proceed the classical role of hCG during pregnancy and could be a directly involved in and facilitating the implantation process. Studies have been conducted to study the effect of injection of different concentrations of hCG inside the uterine cavity before Embryo Transfer (ET) to improve endometrial receptivity and outcomes of In-Vitro Fertilization (IVF) or Intra-Cytoplasmic Sperm Injection (ICSI) cycles. A recent systematic review was conducted on 12 studies performing intrauterine injection of different doses of hCG before ET. Results of this study showed that there is increased pregnancy outcome after injection of intrauterine 500 IU of hCG. The study recommended a definitive large clinical trial with live birth as the primary outcome. There was no evidence that miscarriage was influenced by intrauterine hCG administration, irrespective of embryo stage at transfer or dose of intrauterine hCG. Aim of the study: To detect whether intrauterine injection of hCG before ET improves clinical outcomes in IVF/ICSI cycles.
This will be a prospective, randomized (1:1 ratio) clinical trial for non-male factor infertility in advanced maternal age with or without intracytoplasmic sperm injection(ICSI). Qualified 1422 patients are randomized into either of two groups: group A will undergo conventional in-vitro fertilization(IVF)(711 cases), Group B will undergo intracytoplasmic sperm injection (ICSI) (711 cases). All participants will receive the same protocol for ovarian stimulation and standardized luteal phase support. The target population will be patients with non-male factor infertility aged ≥38years with FSH ≤15. Women with other reasons of infertility (eg. anovulation, endometriosis, and premature ovarian failure) are excluded. The randomization will take place before controlled ovarian stimulation by a computer randomization system. The accumulated live birth rate , pregnancy complications will be followed up by checking medical records and telephone calls.
The investigators propose the Delivery Optimization for Antiretroviral Therapy Study - The DO ART Study - a prospective randomized study of strategies to optimize community-based ART initiation, monitoring and resupply among HIV-positive persons in South Africa and Uganda. The investigators will work closely with community members, stakeholders, local providers, and the local Department of Health (DoH) to integrate the community-based ART delivery with HIV clinics, pharmacies and labs. Following community sensitization, participants will be recruited through community-based HTC and HIV clinics. HIV-positive persons not engaged in care will receive point-of-care CD4 testing to determine ART eligibility. HIV-positive persons who are eligible for ART by national guidelines will be randomized to one of three ART delivery arms: (i) Home ART initiation and mobile van ART monitoring and resupply, (ii) Hybrid model with clinic ART initiation and mobile van ART monitoring and resupply, and (iii) Clinic ART initiation, monitoring and resupply - the current standard of care (SOC)
Aim of the study is to evaluate the effects of a change in the intestinal microflora on the neuro-cognitive profile of patients with HIV infection receiving HAART treatment. Improvements will be evaluated with questionnaires on Quality of life and Cognitive and Behavior function. 20 patients will be enrolled and will receive 4 sachets of VSL#3 per day.
The aim of this study is to evaluate the potential benefits in implantation, clinical pregnancy and live birth rates by an endometrial biopsy prior to an IVF/ICSI treatment. Including a follow up on possible pregnancy complications and data on children at birth. Further it is planned to aspirate secretions from the uterus and take blood samples during the treatment, which presumably can provide information about the mechanisms underlying the possible effect of the treatment.
