A hope for postoperative symptomatic endometriosis therapy

A new chapter in the treatment of symptomatic endometriosis patients may begin since new medical approaches including oral GnRH antagonists, selective progesterone receptor modulators, aromatase inhibitors, and peritoneal immune response modulators are being actively evaluated. To date, there was only one oral GnRH antagonist that was approved for use in the United States, Canada, and Israel. However, there was a necessity for a dose and duration change based on the symptoms and findings of endometriosis patients. Surrey SE., from Colorado Center…

Is oocyte cryopreservation useful for fertility preservation in ovarian endometriosis?

Women with endometriosis tend to have lower fecundity compared to normal couples. Furthermore,  endometrioma itself may reduce the ovarian reserve by altering ovarian physiology in the surrounding healthy ovarian tissue. The treatment for endometrioma is surgical removal in most cases, however, it may ve associated with the risk of premature ovarian failure. Kim SJ et al., a group of researchers from Korea, analyzed the clinical characteristics and controlled ovarian stimulation outcomes of fertility preservation of women with endometrioma, and sub-analyzed the results…

Fatigue from the viewpoint of patients with endometriosis

Fatigue, feeling spoonie, is documented as a significant symptom of endometriosis in many studies. Researchers from three different institutions dealing with reproductive health conducted individual interviews with patients reporting moderate to severe endometriosis-related pain to better understand endometriosis-related fatigue and its effect on patients. The study sample included 22 endometriosis patients who had a mean age of 38.6 years (range, 27-48 years). The research team found that symptoms reported by endometriosis patients were fatigue (100%), pain with periods (86.4%), heavy…

Are endometriosis patients at higher risk of bipolar disorder?

Endometriosis patients are prone to develop certain psychiatric disorders, including depression and anxiety, as well as bipolar disorder, according to a nationwide population-based cohort study from Taiwan. Bipolar disorder formerly called manic-depression is a chronic mental disorder characterized by unusual changes in mood, energy, activity level, and ability to perform daily tasks and fatigue. Chen et al., researchers from Taiwan, investigated the risk of bipolar disorder development in women with endometriosis as well as the effect of endometriosis treatment on the…

The efficacy of combined hormonal contraception on pelvic pain in endometriosis patients

Chronic pelvic pain, which is experienced by more than 33% of endometriosis patients, constitutes a significant challenge for patients and physicians. A new study that appears in the journal Human Reproduction Open has explored the prevalence of endometriosis patients with a history of combined hormonal contraception (CHC) ineffectiveness for pain or discontinuation due to side-effects. The researchers have also determined the association between CHC ineffectiveness or discontinuation due to side-effects and quality-of-life, psychological scores, and underlying pain conditions.

Long-term Pregnancy Results after Surgical Removal of Endometrioma

Sun et al., from China, investigated the pregnancy outcomes and the related factors in patients with endometrioma and stage III-IV endometriosis along with a long-term follow-up postoperatively. Their study has recently been published in the journal named "Advances in Therapy". Among 347 patients with ovarian endometriosis, 59 infertile patients with stage III-IV endometriosis who had a minimum of 5 years of postoperative follow-up after undergoing laparoscopic excision of ovarian endometriomas were included in the study.

Kisspeptin and its Receptor in the Pathogenesis of Endometriosis

It is known that matrix metalloproteinases (MMP) may play a role in the pathogenesis of endometriosis. For example, the upregulation of MMP-2 and MMP-9 may enhance the degradation of extracellular matrix proteins, facilitating cell migration and invasion. Kisspeptin (KISS1, also known as metastin), a neuropeptide hormone, encoded by the KISS1 gene, may interact with MMPs in endometrial tissue. Abdelkareem et al. evaluated the immunoreactivity of KISS1 and its receptor in the eutopic endometrium of patients with and without endometriosis, in…

The relationship of serum concentrations of neuropilin-1 (NRP-1) and endometriosis

Although many serum biomarkers or biomarker panels for endometriosis are evaluated, none of them is exact enough to be used in daily laboratory practice. In a recent study, which has been published in Scandinavian Journal Of Clinical and Laboratory Investigation, Barberic et al., researchers from Croatia, aimed to investigate the serum concentration of neuropilin-1 (NRP-1) in women with endometriosis and to evaluate the level of NRP-1 to preoperatively predict the diagnosis of endometriosis. NRP-1 is is a transmembrane glycoprotein that serves…

A nonhormonal treatment of endometriosis: Dichloroacetate

In women with endometriosis, peritoneal mesothelial cells show higher glycolysis, lower mitochondrial respiration, decreased enzymatic activity of pyruvate dehydrogenase and increased production of lactate compared to women without the disease. Transforming growth factorβ1 and lactate are elevated in the peritoneal fluid of endometriosis patients. Lactate can stimulate cell migration and invasion, and immune escape during tumorigenesis, with the same processes implicated in the etiology of endometriosis. Increased lactate concentrations in the pelvic peritoneal fluid may facilitate the invasion of ectopic…
