Actual (reported)Endometriosis is a chronic gynecological condition affecting nearly 10% of women of reproductive age. A definitive diagnosis of endometriosis requires laparoscopy. Studies aim to identify novel biomarkers to aid in the development of effective noninvasive diagnostic methods. Despite several theories, the full understanding of the etiopathogenesis remains elusive. A distorted immune response is thought to play a crucial role in the pathophysiology of endometriosis. This study aimed to evaluate whether the levels of alternative complement molecules change in the blood serum and peritoneal fluid of endometriosis patients compared to healthy subjects.

Serum samples were collected via antecubital venous blood sampling. In the study group, serum samples were obtained just before laparoscopy, while peritoneal fluid (PF) samples were collected from the Douglas pouch at the time of trochar insertion into the abdominal cavity. Serum and PF MASP-3, adipsin, properdin, and CFH levels were evaluated.
