Effect of single-dose ibuprofen on follicular fluid levels of interleukins in poor responders undergoing in vitro fertilization

Abstract

ABSTRACTPremature follicular rupture during in vitro fertilization (IVF) is a well-known culprit for cycle cancellation. We sought to evaluate whether a single oral dose of ibuprofen will have an effect on the follicular fluid (FF) levels of inflammatory markers involved in ovulation. This is a prospective within-subjects study following nine patients undergoing IVF. Every patient underwent a first cycle of minimal stimulation IVF followed by a second cycle using the same stimulation protocol, except one oral dose of ibuprofen 800 mg was administered 15–18 h post-trigger injection. FF was obtained during oocyte retrievals of both cycles and analyzed for levels of selected inflammatory markers. A total of 27 cytokines and 9 matrix metalloproteinases (MMPs) were tested. Results demonstrate significantly decreased levels of interleukin (IL)-6, IL-8, granulocyte-colony stimulating factor (G-CSF), eotaxin, MMP3, MMP7, MMP12, and MMP13 in FF of cycles where ibuprofen was administered. However, other cytokines levels, such IL-1 and vascular endothelial growth factor (VEGF), were similar with or without ibuprofen. Levels of MMPs described to be involved in ovulation, namely MMP-2 and MMP-9, were either undetectable or unchanged by ibuprofen, respectively. In conclusion, our data show that one dose of ibuprofen administered orally the day after trigger injection revealed a significant impact on the FF inflammatory milieu.Abbreviations: IVF: in vitro fertilization; MMP: matrix metalloproteinase; IL: interleukins; FF: follicular fluid; VEGF: vascular endothelial growth factor; NSAIDS: non-steroidal anti-inflammatories; POR: poor ovarian response; AMH: anti-Mullerian hormone; TAFC: total antral follicle count; HMG: human menopausal gonadotropin; hCG: human chorionic gonadotropin; COX: cyclooxygenase enzymes; PGH2: prostaglandin H2; RANTES: regulated on activation, normal T expressed and secreted; NF-κb: nuclear factor kappa-light-chain-enhancer of activated B cells
