OBJECTIVE To quantify the impact of endometriosis-related symptoms on physical and mental health status, health-related quality of life, and work-related aspects (absenteeism, presenteeism, work productivity, and activity impairment). DESIGN Cross-sectional quantitative study. SETTING Academic and research institution. PATIENT(S) Women (n = 193) with(More)
The objective of this study was to assess the burden of endometriosis by obtaining patient-reported outcome data describing the experience of living with this disease. Survey data from 107 women with self-reported, surgically diagnosed endometriosis showed that living with this disease may be characterized by physical limitations that disrupt health, work,(More)
Endometriosis is found in 5-15% of women of reproductive age and is more frequent in relatives of women with the disease. Activation of KRAS results in de novo endometriosis in mice, however, activating KRAS mutations have not been identified in women. We screened 150 women with endometriosis for a polymorphism in a let-7 microRNA (miRNA) binding site in(More)
Epigenetic mechanisms have been ascribed important roles in endometriosis. Covalent histone modifications at lysine residues have been shown to regulate gene expression and thus contribute to pathological states in many diseases. In endometriosis, histone deacetylase inhibition (HDACi) resulted in reactivation of E-cadherin, attenuation of invasion,(More)
Endometriosis is associated with activation of local and systemic inflammatory mechanisms, including increased levels of chemokines and other proinflammatory cytokines. We have previously reported increased gene expression of chemokine receptor 4 (CXCR4), the receptor for CXCL12, in lesions of the rat model of endometriosis. The CXCR4-CXCL12 axis has been(More)
TNF-alpha is known to play an important role in inflammatory bowel disease (IBD); however, the pathophysiological role of its receptors is still under study. Acute colitis was induced in rats by intracolonic administration of trinitrobenzene sulfonic acid (TNBS). Control rats received the ethanol vehicle. Rats were sacrificed 72 h later and samples of(More)
OBJECTIVE To identify molecular biomarkers for endometriosis in peripheral blood lymphocytes by using DNA microarrays. DESIGN Case-control. SETTING Multicenter academic research programs. PATIENT(S) Premenopausal women with or without endometriosis, determined by obstetrics and gynecology specialists during surgery. Microarray analysis included six(More)
BACKGROUND Endometriosis is an inflammatory disease that is defined by growth of endometrial tissue outside the uterus, resulting in pain, infertility, and emotional distress. Previous studies have shown that the HPA axis is compromised in patients with chronic, painful diseases, including endometriosis. However, the underlying mechanisms and the(More)
OBJECTIVE To determine the prevalence of endometriosis and its symptoms in a Puerto Rican cohort, and to describe the menstrual, obstetric, and clinical profiles of the women. METHODS A self-administered questionnaire was given to 1285 Puerto Rican women. Categorical variables were compared using chi2 analysis or Fisher exact test. RESULTS There were 57(More)
This study was conducted to assess genetic associations with endometriosis in a Puerto Rican population. Statistically significant differences in the allelic frequencies and genotype distribution of genetic variants in lysyl oxidase-like protein 4 (LOXL4) and complement component 3 (C3) were documented in patients with endometriosis-associated infertility(More)
