Estrógeno potenciado en el tratamiento homeopático del dolor pélvico asociado a endometriosis: un estudio aleatorizado, doble ciego, controlado con placebo, de 24 semanas / Potentiated estrogen in the homeopathic treatment of pelvic pain associated with endometriosis: a 24-week randomized, double-blind, placebo-controlled study

Evaluar la eficacia y seguridad del estrógeno potenciado en comparación con el placebo en el tratamiento homeopático del dolor pélvico asociado a endometriosis (EAPP, por sus siglas en inglés). Diseño del estudio: El presente fue un estudio clínico aleatorizado, doble ciego, controlado con placebo, de 24 semanas, el cual incluyó a 50 mujeres de entre 18 y 45 años de edad con diagnóstico de endometriosis infiltrante profunda con base en ultrasonido transvaginal o imágenes de resonancia magnética después de preparación intestinal, así como puntaje ≥ 5 en una escala visual analógica (VAS: rango de 0 a 10 puntos) para el dolor pélvico asociado con la endometriosis. Se administró estrógeno potenciado (12cH, 18cH y 24cH) o placebo dos veces al día por vía oral. La medida principal de resultado fue el cambio en la severidad de los puntajes parcial y global de EAPP (VAS) de la línea basal a la semana 24, determinada como la diferencia en el puntaje medio de cinco modalidades de dolor pélvico crónico (dismenorrea, dispareunia profunda, dolor pélvico no cíclico, dolor intestinal cíclico y/o dolor urinario cíclico). Las medidas secundarias de resultado fueron la diferencia media de puntaje para la calidad de vida evaluada con el Cuestionario de Salud SF-36, los síntomas de depresión en el Inventario de la Depresión de Beck (BDI) y los síntomas de ansiedad en el Inventario de Ansiedad de Beck (BAI). Resultados: El puntaje global de EAPP (VAS: rango de 0 a 50 puntos) se redujo en 12.82 (p < 0.001) en el grupo tratado con estrógeno potenciado de la línea basal a la semana 24. El grupo que utilizó estrógeno potenciado también presentó una reducción en el puntaje parcial (VAS: rango de 0 a 10 puntos) en tres modalidades de EAPP: dismenorrea (3.28; p < 0.001), dolor pélvico no cíclico (2.71; p = 0.009) y dolor intestinal cíclico (3.40; p < 0.001). El grupo de placebo no mostró cambio significativo alguno en los puntajes global o parcial de EAPP. Además, el grupo de estrógeno potenciado mostró un mejoramiento significativo en tres de ocho ámbitos de SF-36 (dolor de cuerpo, vitalidad y salud mental) y síntomas de depresión (BDI). El grupo de placebo no mostró un mejoramiento significativo a este respecto. Estos resultados demuestran la superioridad del estrógeno potenciado sobre el placebo. Se asociaron pocos eventos adversos con el estrógeno potenciado. Conclusiones: El estrógeno potenciado (12cH, 18cH y 24cH) en dosis de 3 gotas dos veces al día durante 24 semanas fue significativamente más efectivo que el placebo para reducir el dolor pélvico asociado con la endometriosis.

To evaluate the efficacy and safety of potentized estrogen compared to placebo in homeopathic treatment of endometriosis-associated pelvic pain (EAPP). Study design: The present was a 24-week, randomized, doubleblind, placebocontrolled trial that included 50 women aged 18-45 years old with diagnosis of deeply infiltrating endometriosis based on magnetic resonance imaging or transvaginal ultrasound after bowel preparation, and score ≥ 5 on a visual analogue scale (VAS: range 0 to 10 points) for endometriosis-associated pelvic pain. Potentized estrogen (12cH, 18cH and 24cH) or placebo was administered twice daily per oral route. The primary outcome measure was change in the severity of EAPP global and partial scores (VAS) from baseline to week 24, determined as the difference in the mean score of five modalities of chronic pelvic pain (dysmenorrhea, deep dyspareunia, non-cyclic pelvic pain, cyclic bowel pain and/or cyclic urinary pain). The secondary outcome measures were mean score difference for quality of life assessed with SF-36 Health Survey Questionnaire, depression symptoms on Beck Depression Inventory (BDI), and anxiety symptoms on Beck Anxiety Inventory (BAI). Results: The EAPP global score (VAS: range 0 to 50 points) decreased by 12.82 (p < 0.001) in the group treated with potentized estrogen from baseline to week 24. Group that used potentized estrogen also exhibited partial score (VAS: range 0 to 10 points) reduction in three EAPP modalities: dysmenorrhea (3.28; p < 0.001), non-cyclic pelvic pain (2.71; p = 0.009), and cyclic bowel pain (3.40; p < 0.001). Placebo group did not show any significant changes in EAPP global or partial scores. In addition, the potentized estrogen group showed significant improvement in three of eight SF-36 domains (bodily pain, vitality and mental health) and depression symptoms (BDI). Placebo group showed no significant improvement in this regard. These results demonstrate superiority of potentized estrogen over placebo. Few adverse events were associated with potentized estrogen. Conclusions: Potentized estrogen (12cH, 18cH and 24cH) at a dose of 3 drops twice daily for 24 weeks was significantly more effective than placebo for reducing endometriosis-associated pelvic pain.

Hormonal treatment isolated versus hormonal treatment associated with electrotherapy for pelvic pain control in deep endometriosis: Randomized clinical trial.

OBJECTIVE: The aim of the study was to evaluate the clinical effectiveness of complementary treatment using self-applied electrotherapy treatment for pain control over the standard hormonal treatment alone for deep infiltrative endometriosis (DIE). STUDY DESIGN: Multicentre randomized clinical trial. We included a hundred-one participants with DIE in electrotherapy (n = 53) (hormonal treatment + electrotherapy) or control group (n = 48) (only hormonal treatment) by 8 weeks of follow-up. The primary measurement was chronic pelvic pain (CPP) using a visual analogue scale (VAS) and deep dyspareunia. The secondary outcomes were the quality of life by endometriosis health profile (EHP-30) and sexual function by female sexual function index (FSFI). RESULTS: CPP relief was observed only in the electrotherapy group (pre:7.11 ± 2.40, post:4.55 ± 3.08, p < 0.001). In terms of deep dyspareunia, improvements were observed for both groups (electrotherapy pre:2.02 ± 0.54-1.36 ± 0.96, p < 0.001; control pre:1.95 ± 0.86-1.68 ± 0.82, p = 0.006). Considering the secondary outcomes, a higher total score post-treatment for the EHP-30 was noted in both groups. Regarding sexual function, there was a statistically significant improvement in the FSFI score for the electrotherapy group (p < 0.001), with an increase in the scores for lubrication and pain domains (p = 0.013 and p < 0.001). CONCLUSIONS: Electrotherapy treatment using transcutaneous electrical nerve stimulation proved to be a good complementary option for pain control, showing benefits in the reduction of CPP and deep dyspareunia and improving patient's quality of life and sexual function.

The Effect of Rutin and Extracts of Uncaria guianensis (Aubl.) J. F. Gmeland on Primary Endometriotic Cells: A 2D and 3D Study.

There is increasing interest in the potential of natural compounds to treat diseases, such as endometriosis, a gynecological disorder that affects 10-15% of women of reproductive age, and it is related to severe pelvic pain and infertility. We have evaluated the in vitro effects of rutin and the aqueous bark, roots, and leaf extracts (ABE, ARE, and ALE, respectively) and isolated components of Uncaria guianensis on stromal cells from eutopic endometrium and lesions of patients with endometriosis. Two- and three-dimensional cultures were used to assess the cell death and production of reactive oxygen species (ROS), cytokines and growth factors of cells following exposure to these natural products. The applied treatments did not reduce cellular viability, but ROS production did increase. In addition, significant increases in the levels of interleukin (IL)-15, IL-17A, IL-4, IL-6, tumor necrosis factor-α, and vascular endothelium growth factor were observed when 2D-cells from endometrium of patients with endometriosis were treated with ABE, while exposure to ALE induced significant increases in epidermal growth factor in lesion cells.

Protocol of randomized controlled trial of potentized estrogen in homeopathic treatment of chronic pelvic pain associated with endometriosis.

BACKGROUND: Endometriosis is a chronic inflammatory disease that causes difficult-to-treat pelvic pain. Thus being, many patients seek help in complementary and alternative medicine, including homeopathy. The effectiveness of homeopathic treatment for endometriosis is controversial due to the lack of evidences in the literature. The aim of the present randomized controlled trial is to assess the efficacy of potentized estrogen compared to placebo in the treatment of chronic pelvic pain associated with endometriosis. METHODS/DESIGN: The present is a randomized, double-blind, placebo-controlled trial of a homeopathic medicine individualized according to program 'New Homeopathic Medicines: use of modern drugs according to the principle of similitude' (http://newhomeopathicmedicines.com). Women with endometriosis, chronic pelvic pain and a set of signs and symptoms similar to the adverse events caused by estrogen were recruited at the Endometriosis Unit of Division of Clinical Gynecology, Clinical Hospital, School of Medicine, University of São Paulo (Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo - HCFMUSP). The participants were selected based on the analysis of their medical records and the application of self-report structured questionnaires. A total of 50 women meeting the eligibility criteria will be randomly allocated to receive potentized estrogen or placebo. The primary clinical outcome measure will be severity of chronic pelvic pain. Statistical analysis will be performed on the intention-to-treat and per-protocol approaches comparing the effect of the homeopathic medicine versus placebo after 24 weeks of intervention. DISCUSSION: The present study was approved by the research ethics committee of HCFMUSP and the results are expected in 2016.
