Pain Reduction with an Immersive Digital Therapeutic in Women Living with Endometriosis-Related Pelvic Pain: at-home self administered randomized controlled trial

BACKGROUND

The management of chronic pelvic pain in women with endometriosis is complex and includes long-term use of opioids. Patients not fully responsive to drugs, or ineligible for surgical treatments need efficient alternatives to improve their quality of life and avoid long-term sequelae.

OBJECTIVE

This randomized controlled trial, software under test (Endocare) vs. sham, aimed to assess the effects of repeated at home administrations of a 20-minutes virtual reality (VR) solution on pain in women experiencing pelvic pain due to endometriosis.

METHODS

Patients were instructed to use VR headsets twice daily during at least 2 days and up to 5 days starting on their first day of painful periods. Pain perception was measured using a numerical scale (0 - 10) before and 60, 120, 180 minutes after each treatment administration. General pain, stress, fatigue, medication intake and quality of life were daily reported by patients.

RESULTS

102 patients were included in the final analysis (Endocare: n=51/102, 50%; Sham: n= 51/102; 50%). The mean age was 32.88 years (SD 6.96) and the mean pain intensity before treatment was 6.53 (SD 1.74) and 6.22 (SD 1.69) for the Endocare group and the control group (P=.48). Pain intensity decreased in both groups from day 1 to day 5 as well as medication use. Maximum pain intensity reduction was 51.58% (SD 35.33) at D2.T120 and 27.37% (SD 27.23) at D3.T180 for the Endocare group and the control group respectively. The Endocare was significantly superior to the sham on day 1 (T120, P=.037; T180, P=.001), day 2 (T0, P=.022; T60, T120, T180, all P<.0001) and day 3 (T60, P=.014; T120, P=.005; T180, P=.001). Similarly, the mean perceived pain relief was significantly higher with Endocare on day 1 (T120, T180) and day 2 (T60, T120, T180) compared to the control (All P<.01). No adverse event was reported.

CONCLUSIONS

This study confirmed the effectiveness and safety of self-repeated administrations of a virtual reality immersive treatment used at home while reducing overall pain medication intake in women diagnosed with endometriosis experiencing moderate-to-severe pelvic pain and supports.

Preventive therapeutic options for postoperative recurrence of ovarian endometrioma: gonadotropin-releasing hormone agonist with or without levonorgestrel intrauterine system insertion

PURPOSE

Here, we compared endometrioma recurrence rates in patients who have undergone a laparoscopic cystectomy and treated with a gonadotropin-releasing hormone agonist (GnRHa) alone or a GnRHa combined with a levonogestrel intrauterine system (LND-IUS).

METHODS

We enrolled endometrioma patients who underwent laparoscopic cyst enucleation and divided them into two groups according to postoperative management: GnRHa alone and GnRHa in combination with LND-IUS. We compared preoperative history, perioperative parameters, postoperative endometrioma recurrence, and symptoms between these two groups.

RESULTS

A total of 320 patients were included in the final analysis. With a median 84.6 months of follow-up, we detected significant differences between the two groups with respect to age at surgery (31.6 ± 4.8 vs. 37.6 ± 4.2 years, χ² = 1.978, p < 0.001), gravida (0 vs. 2, χ² = 4.391, p < 0.001), parity (0 vs. 1, χ² = 0.035, p < 0.001), body mass index (21.0 ± 2.5 vs. 21.9 ± 2.4, χ² = 0.0096, p = 0.009), r-AFS score (48 vs. 64, χ² = 4.888, p = 0.001), and operation time (60 vs. 75 min, χ² = 9.119, p = 0.003). Patients treated with both GnRHa and LND-IUS achieved significantly less endometrioma recurrence (23.6 vs. 11.5%, χ² = 5.202, p = 0.023) and higher rates of pain remission (92.1 vs. 100%, χ² = 6.511, p = 0.011), while those with GnRHa alone suffered more recurrent and painful symptoms (χ² = 9.280, p = 0.026). Multivariate analysis using a Cox regression demonstrated that combined GnRHa and LNG-IUS treatment correlated with a decreased endometrioma recurrence rate after laparoscopic cystectomy (RR 0.369, 95% CI 0.182-0.749, p = 0.006).

CONCLUSIONS

Combination treatment of GnRHa and LNG-IUS exhibited superior pain relief and recurrence prevention among endometrioma patients after fertility-sparing surgery. Thus, combination treatment is a preferable long-term option for patients without intent for pregnancy in the near future.

New therapeutic approaches for endometriosis besides hormonal therapy

Supplemental Digital Content is available in the text

Objective:

Endometriosis is a common gynecologic disease that frequently leading to chronic pelvic pain, severe dysmenorrhea, and subfertility. As first-line hormonal treatment can interfere with ovulation and may cause recurrent pelvic pain, exploration of new non-hormonal therapeutic approaches becomes increasingly necessary. This review aimed to evaluate the pre-clinical and clinical efficacy and safety of non-hormonal treatment for endometriosis

Data sources:

Databases including PubMed, Embase, Cochrane Library, SINOMED, ClinicalTrials.gov, and Google Scholar were searched up to October 2019, using search terms “endometriosis” and “non-hormonal therapy.”

Study selection:

Twenty-four articles were reviewed for analysis, including nine animal studies and 15 human trials; all were published in English.

Results:

Twenty-four articles were identified, including 15 human trials with 861 patients and nine animal studies. Some agents have been evaluated clinically with significant efficacy in endometriosis-related pelvic pain and subfertility, such as rofecoxib, etanercept, pentoxifylline, N-palmitoylethanolamine, resveratrol, everolimus, cabergoline (Cb2), and simvastatin. Other drugs with similar pharmacological properties, like parecoxib, celecoxib, endostatin, rapamycin, quinagolide, and atorvastatin, have only been tested in animal studies.

Conclusions:

Clinical data about most of the non-hormonal agents are not sufficient to support them as options for replacement therapy for endometriosis. In spite of this, a few drugs like pentoxifylline showed strong potential for real clinical application.
