Differences in gene expression provide evidence of progesterone resistance in midsecretory PCOS endometrium, independent of clomiphene citrate and corresponding to the observed phenotypes of hyperplasia, cancer, and poor reproductive outcomes in this group of women.
When combined with ceftriaxone, 1g of azithromycin weekly for 2 weeks is equivalent to ceftriaxone plus a 14-day course of doxycycline for treating mild PID.
Human endometrium undergoes modifications in preparation for embryonic implantation. This study investigated in vivo the endocrine effects of pregnancy on the endometrium, using the model of ectopic pregnancy. Endometrial biopsies from 9 subjects with ectopic pregnancy (Preg) were compared with 8 and 6 samples of mid and late secretory endometrium, respectively. After hybridizing with Affymetrix HGU133 Plus 2 chips, data were analyzed using GeneSpring GX and Ingenuity Pathways Analysis. From 54,675 genes, 3021 genes were significantly differentiated when mid-secretory endometrium was compared with the Preg (Volcano plot; P < .05, >or=2-fold change).The complement and coagulation cascade, phospholid degradation, glycosphingolipid biosynthesis (globoseries), retinol metabolism, antigen presentation pathway, glycosphingolipid biosynthesis, and O-glycan biosynthesis were main significant canonical pathways found in Preg samples. Validation was done with reverse transcriptase polymerase chain reaction. In conclusion, the ectopic embryo has a significant impact, by an endocrine mechanism, on endometrium, when compared with the window of implantation.
Hydrosalpinx is a common condition among women of reproductive age. It is related to low pregnancy rates in the settings of in vitro fertilization-embryo transfer programs. Such low rates are not yet well understood, and may be due to poor endometrial receptivity and abnormal expression of key molecules in the endometrium that are important for implantation. The available data on the inflammatory response, endometrial blood flow, integrins, leukemia inhibitory factor, matrix metalloproteinases, and homeobox gene A10 expression in the presence of hydrosalpinx are reviewed. In addition, the evidence for treatment options to improve pregnancy rates is also discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
