Subanalysis on subgroups at particular high risk such as those with Polycystic ovaries, unexplained fertility and recurrent implantation failure will be undertaken to see if there is any correlation with immune, endothelial or platelet function changes. ![]() Third, although the lipid emulsion (Intralipid) dosing regimen required to. The third dose of Intralipid is administered around the time immediately after a positive pregnancy test. First, a toxic dose of bupropion, a highly lipid soluble. The second dose is administered around the time of embryo transfer. All trials included women with previous implantation failure. All trials used a normal saline infusion or no intervention (routine care) as a comparator (Table 1). The first dose of Intralipid is administered during the mid-stimulation phase of the IVF cycle. Four trials administered a second dose of intralipid following a positive pregnancy test and one continued intralipid administration fortnightly until the end of the first trimester. Each research participant will have 3 infusions of Intralipid. There is will be no change in clinical practice other than additional blood samples being taken at the beginning and at the end of each infusion. Does this possible relationship change throughout the treatment with Intralipid, is it related to endothelial function and platelet function and is there any effect on pregnancy rates following the Intralipid infusionĬurrently intralipid is being used in clinical practice according to this protocol. This research project is one year study to assess whether there is a relationship between baseline immune function through peripheral and uterine natural Killer cell ratios prior to Intralipid infusions. The suppressive effect following 3 infusions of Intralipid lasted between 6 and 9 weeks on average. dose when got pregnant within the 1st week of positive pregnancy test, while group B (n102) subjects were control group and not given Intralipid. Intralipid has been shown to be effective in suppressing these cells in patients with recurrent implantation failure although this only looked into Peripheral Natural Killer cells. Recent studies have shown that immune function through peripheral and uterine Natural Killer cells may be associated with this problem. Failure of the embryo to implant is a major problem in IVF.
