SIRM at this point typically recommends IL instead of IViG

Response to what about intralipids

At this point they suggest that intralipids are as effective in IViG in most cases. I think they've been advocating that since around 2009, and then they pointed us to a few articles.

Here is one showing equal effectiveness in both patients with "normal" NK cells and those with activated NK cells

Natural killer cell functional activity suppression by intravenous immunoglobulin, intralipid and soluble human leukocyte antigen-G.

Roussev RG, Ng SC, Coulam CB.

Millenova Immunology Laboratories, Chicago, IL 60611, USA.

PROBLEM: The purpose of this study was to compare the ability of intravenous immunoglobulin (IVIg), intralipid and soluble human leukocyte antigen (sHLA)-G to suppress natural killer (NK) cell cytotoxicity in an in vitro assay.

METHOD OF STUDY: Blood samples taken from 275 women experiencing reproductive failure were analyzed for NK cytotoxicity and the suppression of NK cytotoxicity by IVIg 4 and 2 mg/mL (n = 275), intralipid 18 and 9 mg/mL (n = 275) and sHLA-G 70 and 35 ng/mL (n = 50) using immunofluorescent labeled K562 cells as targets and flow cytometry.

RESULTS: Natural killer cytotoxicity was suppressed in all samples. Among patients with normal NK cell activity, IVIg suppressed NK cytotoxicity by 44.9 +/- 8.1%, intralipid suppressed NK killing by 45.2 +/- 8.3% and sHLA-G suppressed by 49.0 +/- 9.2%. When specimens with abnormal NK activity were observed for suppression of cytotoxicity, IVIg suppressed by 38.9 +/- 5.4%, intralipid suppressed by 39.8 +/- 6.2% and sHLA-G suppressed by 39.9 +/- 5.0%.

CONCLUSION: Intravenous immunoglobulin, intralipid and sHLA-G suppressed NK cell cytotoxicity with equal efficacy in an in vitro assay.

Removed Uterine Septum and polyps in 2009 (Dr Sher said this was BAD, could have created scar tissue. Hysteroscopy soon to see)
