Brief summary
Endometriosis is a common gynecological benign disease which significantly compromise quality of life in patients and is a major cofactor of infertility. With the proteomic approach the investigators will search for proteins with significantly different levels in peritoneal fluid, serum and uterine fluid samples of women with endometriosis versus control group. Results will be validate using ELISA aproach.
Detailed description
Informed consent will be obtained from all individual participants included in the study. Blood sample will be obtained the day before laparoscopic surgery during regular clinical preoperative procedures. Peritoneal fluid and uterine fluid will be obtained during regular laparoscopic procedure indicated for infertility, the exact protocol of sample obtaining will be revealed after publication of results. The aim of the study was to identify potential diagnostic and predictive biomarkers or drug targets.
Interventions
DIAGNOSTIC_TESTproteomic analyses, ELISA validation of peritoneal fluid, blood and uterine fluid sample
All samples were collected during laparoscopy, before any intraabdominal procedure was done. Indication for surgery was clinical (not for research purpose). All sample collection procedures was mimic regular clinical procedures.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Derivation of the panel of proteins indicative of endometriosis using comparative proteomics | 3 years to collect all speciments | The aim of the study is to identify proteins with different levels in cases versus controls these proteins could be new candidates for biomarkers of endometriosis. Differentially expressed proteins are candidates for diagnostic and predictive biomarkers. To identify differentially expresed proteins in discovery phase of the study proteomic aproach will be used. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Concentrations of proteins in body fluids to validate the identified panel of proteins indicative of endometriosis | 3 years to collect all speciments | Using pairs of subjects with and without endometriosis, the derivation of the panel of proteins in body fluids (peritoneal fluid, peripheral blood, uterine fluid samples) gathered through proteomic aproach will be validated using ELISA. |
