Continuous versus cyclic oral contraceptives for endometriosis: any conclusive evidence?

A systematic review of the mechanistic actions of microRNAs within integrated traditional Chinese medicine and western medical treatment for endometriosis

Endometriosis (EM), also known as Zhengjia in traditional Chinese medicine, is a common disease that significantly impacts women's health. An integrated treatment approach combining traditional Chinese medicine (TCM) and western medicine has demonstrated significant clinical efficacy in the management of this condition. Specifically, it has been effective in addressing blood circulation and other diseases. MicroRNAs (miRNAs), which are molecules important in gene regulation, have been implicated in various physiologic and pathologic processes. In this review, we systematically summarized the potential mechanisms underlying the integrated EM treatment, with a focus on the role of microRNAs (miRNAs). Current research suggests that integrated TCM and western medicine treatment may exert their therapeutic effects on EM by influencing the expression of miRNAs. Through miRNA modulation, such a treatment approach may inhibit the growth of ectopic lesions and alleviate clinical symptoms. This review will shed light on the specific miRNAs that have been implicated in the integrated treatment of EM, as well as their potential mechanisms of action. By consolidating the existing evidence, we aim to provide clinicians and researchers with a clearer understanding of the therapeutic benefits of the integrated approach and potentially identify new avenues for improving clinical treatment outcomes. Ultimately, this review will contribute to the growing body of knowledge in this field, providing a basis for further research and the development of more targeted and efficient treatment strategies for EM.

Pathophysiology, diagnosis, and management of endometriosis

Endometriosis affects approximately 190 million women and people assigned female at birth worldwide. It is a chronic, inflammatory, gynecologic disease marked by the presence of endometrial-like tissue outside the uterus, which in many patients is associated with debilitating painful symptoms. Patients with endometriosis are also at greater risk of infertility, emergence of fatigue, multisite pain, and other comorbidities. Thus, endometriosis is best understood as a condition with variable presentation and effects at multiple life stages. A long diagnostic delay after symptom onset is common, and persistence and recurrence of symptoms despite treatment is common. This review discusses the potential genetic, hormonal, and immunologic factors that lead to endometriosis, with a focus on current diagnostic and management strategies for gynecologists, general practitioners, and clinicians specializing in conditions for which patients with endometriosis are at higher risk. It examines evidence supporting the different surgical, pharmacologic, and non-pharmacologic approaches to treating patients with endometriosis and presents an easy to adopt step-by-step management strategy. As endometriosis is a multisystem disease, patients with the condition should ideally be offered a personalized, multimodal, interdisciplinary treatment approach. A priority for future discovery is determining clinically informative sub-classifications of endometriosis that predict prognosis and enhance treatment prioritization.

Pharmacologic treatment of the ovarian endometrioma

INTRODUCTION

Treatment of ovarian endometriomas is commonly achieved through laparoscopic surgery and this can be effective in eliminating the disease, although a majority of recent trials documented an adverse effect of surgery on ovarian reserve markers. With the advancement in imaging techniques, ovarian endometriomas are increasingly diagnosed at an earlier stage when the endometrioma may be smaller, less fibrotic and more responsive to medical treatment, making an evaluation of medical options critically important.

AREAS COVERED

The review focuses on currently utilized pharmacologic therapies for endometrioma (oral contraceptives, the levonorgestrel-releasing IUS, the hormone-releasing subdermal implant, Implanon); experimental and future treatments are also mentioned (GnRH antagonists, progesterone receptor modulators, antioestrogens, newer subdermal implants and intracystic administration of pharmacologic agents). Finally, the usefulness of post-operative adjuvant medical treatments is discussed Expert opinion: Today, reliable, non-invasive diagnostic procedures of an ovarian endometrioma are available and should be utilized to identify its presence and type of pathology. In a young patient, classic medical therapies such as oral contraceptives and synthetic progestins should be tried first to alleviate symptoms. Only when these regimens fail, should a minimally invasive surgery be envisaged. Following endoscopic surgery, adjuvant medical treatment may reduce recurrence of both symptoms and the lesion.
