Effect of neurogenic acupoint cupping on high sensitive C-reactive protein and pain perception in female chronic pelvic pain: A randomized controlled trial.

OBJECTIVES: To determine the effect of neurogenic acupoint dry cupping therapy on high sensitive C-reactive protein (hs-CRP) level, pain perception & intensity, and life impact of pelvic pain in women with chronic pelvic pain (CPP), with regard to the biological and neurophysiological impacts of dry cupping on acupoint. METHODS: Thirty women with CPP were randomly divided into two equal groups; the study group received dry cupping on neurogenic acupoints plus lifestyle modifications for 8 weeks (n=15), while the control group received only lifestyle modifications for 8 weeks (n=15). Women were assessed pre- and post-rehabilitation program with the hs-CRP blood test, the short-form McGill Pain Questionnaire (SF-MPQ), and the pelvic pain impact questionnaire (PPIQ). RESULTS: Comparing both groups post-treatment revealed that there were significant reductions in levels of hs-CRP, and scores of SF-MPQ & PPIQ (p<0.05) in the study group compared with the control group. Also, there were significant positive correlations between hs-CRP and both SF-MPQ "Visual Analogue Scale (VAS), Present Pain Intensity (PPI) index & Pain Rating Index (PRI)" and PPIQ (p<0.05). CONCLUSION: Neurogenic acupoint cupping therapy had significantly improving effects on the degree of inflammation, pain perception & intensity, and life impact of pelvic pain in women with CPP.

The potentialities of oxytocin receptor inhibitors for endometriosis therapy.

OBJECTIVE: Genital endometriosis (GE) is a widespread gynecological disease which requires its further pathogenesis investigation and search for new effective treatments. The known data of oxytocin receptor presence in endometrioid heterotopy smooth muscle cells give some grounds to assume oxytocin participation in the pathogenesis of endometriosis. The present study objective was to evaluate oxytocin level in peripheral blood (PB) in patients with endometriosis associated pain syndrome and to estimate the efficacy of oxytocin receptor inhibitors (IOXTR) administration based on animal endometriosis model. MATERIALS AND METHODS: The basic group comprised 61 patients with endometriosis associated pain syndrome, while 21 patients formed the control group. VAS, MPQ, and BBS objective tests were applied for pain syndrome evaluation. Oxytocin level in PB was measured by immunoenzyme method. After confirmation of endometriosis experimental model formation in rats and further randomization, a daily IOXTR intra-abdominal injection was performed in a dose of 0.35 mg/kg/24 h in the basic group (n = 12) or saline solution administration in the control (n = 12). On the final stage, endometrioid heterotopy size measuring was performed along with histological examination. RESULTS: Oxytocin level in PB was authentically higher in patients with GE compared to the control: 51.45 (35.54-62.76) pg/mL and 27.64 (23.23-34.12) pg/mL, respectively (p<.001). Positive correlation between oxytocin PB level and pain syndrome expression was established in patients with GE: VAS (r = 0.76; p<.001), MPQ (r = 0.52; p<.001), and BBS (r = 0.57; p<.001). Based on the experimental disease model authentical decrease of endometrioid heterotopy average area was observed after IOXTR therapy compared to the control (7.3 ± 1.8 mm2 and 22.2 ± 1.2 mm2, respectively, p<.05). CONCLUSIONS: The obtained results confirm the oxytocin role in the pathogenesis of endometrioid associated pain syndrome. The high efficacy of IOXTR administration based on animal model of surgically induced endometriosis allows viewing this method as a perspective therapy.

Short-term benefits of balneotherapy for patients with chronic pelvic pain: a pilot study in Korea.

The aim of this study was to evaluate whether balneotherapy might be effective in patients with chronic pelvic pain (CPP) in the short term. This was an open and prospective pilot study. The balneotherapy programme was performed in a spa resort located in Wando Island, Republic of Korea from August 26 2018 to September 1 2018. It consisted of 10 heated seawater baths (38 °C, 20 minutes) and 10 mud-pack applications (40 °C, 10 minutes) for five days. Sixteen patients were enrolled. Upon analysing responses from a patient questionnaire, we found improvement in parameters such as pain, bladder irrigation symptoms and quality of life after balneotherapy. Inflammatory marker IL-1 and TNF-α was significantly decreased after treatment compared to baseline. There were no adverse events during treatment. Our data suggest that five-day balneotherapy can be beneficial for patients with CPP in the short term.Impact statementWhat is already known on this subject? The majority of articles in the field of balneotherapy discuss the treatment of rheumatic or dermatological disease. However, data on the effectiveness of balneotherapy for chronic pelvic pain are very limited.What the results of this study add? Our study suggests that balneotherapy can be beneficial for patients with CPP in the short-term. The duration of balneotherapy was five days, which is shorter than that of the European studies. Intuitively, it may be doubtful whether short-term therapy has any practical effect. As most people living in Korea have a vacation period of about one week each in summer and winter, the choice of a five-day programme in our study reflects the reality of vacation schedules.What the implications are of these findings for clinical practice and/or further research? Further studies are necessary to demonstrate the persistence of these benefits on the long term, as well as their existence in appropriate control group and different duration of treatment.

Therapeutic effects of Qian-Yu decoction and its three extracts on carrageenan-induced chronic prostatitis/chronic pelvic pain syndrome in rats.

BACKGROUND: Qian-Yu decoction (QYD) is a traditional Chinese medicinal recipe composed of Radix astragali (Astragalus membranaceus (Fisch.) Bunge var. mongholicus (Bunge) P.K. Hsiao, Fabaceae ), Herba epimedii (Epimedium brevicornum Maxim., Berberidaceae), Herba leonuri (Leonurus japonicus Houtt., Lamiaceae), Cortex phellodendri (Phellodendron chinense Schneid., Rutaceae) and Radix achyranthis bidentatae (Achyranthes bidentata Bl., Amaranthaceae). This study aimed to evaluate the therapeutic activity of QYD against carrageenan-induced chronic prostatic/chronic pelvic pain syndrome (CP/CPPS) in rats and further elucidate its effective components. METHODS: Three types of components, total polysaccharides, total flavonoids and total saponins were separately extracted from QYD. Carrageenan-induced CP/CPPS rats were intragastrically administered with lyophilized product of QYD, individual extracts and all the combined forms of extracts for three weeks. Prostatic index (PI) was determined and histopathological analysis was performed. The levels of tumor necrosis factor alpha (TNF-α), interleukin-1 beta (IL-1ß), cyclooxygenase-2 (COX-2) and prostaglandin E2 (PEG2) in rat prostate tissues were measured using ELISA. The production of inducible nitric oxide synthase (iNOS) was evaluated by an enzymatic activity assay, and the release of nitric oxide (NO) was determined by a nitrate/nitrite assay. RESULTS: Treatment with QYD significantly ameliorated the histological changes of CP/CPPS rats and reduced the PI by 44.3%, with a marked downregulation of TNF-α (42.8% reduction), IL-1ß (45.3%), COX-2 (36.6%), PGE2 (44.2%), iNOS (54.1%) and NO (46.0%). Each of three extracts attenuated the symptom of CP/CPPS, but much more weakly than QYD. The combined administration of three extracts showed efficacy comparable to that of QYD while better than that of any combination of two extracts. A principal component analysis of the six inflammatory mediators as variables indicated that the effects of TS on CP/CPPS were rather different from those of TF and TP, which were similar. CONCLUSIONS: QYD can be beneficial in prevention and treatment of CP/CPPS. Polysaccharides, flavonoids and saponins, as the major effective components of QYD, exert a cooperative effect on CP/CPPS.

Acupuncture and immune function in chronic prostatitis/chronic pelvic pain syndrome: a randomized, controlled study.

OBJECTIVE: The immune system has been implicated as one mechanism underlying the benefits of acupuncture therapy. Evidence suggests that acupuncture can ameliorate symptoms of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), but the association between clinical response and the immune system has not been investigated. DESIGN/SETTING: We investigated 12 CP/CPPS patients participating in a prospective randomized clinical trial comparing acupuncture versus sham acupuncture for effects on cellular immunity. Blood samples were taken before the first needling and after the last of 20 treatment sessions (week 10). Patients also completed questionnaires examining their CP/CPPS symptoms and mood status at the baseline and end of study visits. RESULTS: At the end of study 8 of 12 participants (67%) were classified as treatment responders, four participants each from the acupuncture and sham groups. The acupuncture group averaged a 5% increase in natural killer cell levels compared to corresponding sham (-13%; p=0.03). Similarly, patients randomized to acupuncture reported a reduction in other white blood cell parameters examined, supporting the possibility that immunity might be important in the pathophysiology of CP/CPPS. CONCLUSIONS: The specific effect of acupuncture on CP/CPPS remains unclear. Further research is warranted to examine the mechanisms by which acupuncture therapy may improve clinical symptoms in patients with CP/CPPS.

[Common TCM syndrome pattern of chronic pelvic pain syndrome relates to plasma substance p and beta endorphin].

OBJECTIVE: To investigate the relationship of the common Traditional Chinese Medicine (TCM) syndrome pattern of chronic pelvic pain syndrome (CPPS) with the contents of substance p and beta endorphin in the plasma, and provide reference data for the clinical diagnosis, differentiation and treatment of CPPS by TCM. METHODS: We observed 98 cases of CPPS, which were classified into a lower-part damp-heat invasion group (group A, n = 32), a blood stasis-induced collateral obstruction group (group B, n = 34), and a damp-heat stagnation group (group C, n = 32) according to the TCM syndrome differentiation. Another 35 normal healthy young men were enrolled as controls. We measured the contents of substance p and beta endorphin in the plasma by immunoradiometry and ELISA, and analyzed their relationship with the TCM syndrome pattern. RESULTS: The contents of plasma substance p were significantly higher in groups A ([1135.76 +/- 166.45] pg/ml), B ([1 337.84 +/- 170.81] pg/ml), and C ([1 210.01 +/- 162.27] pg/ml) than in the control ([574.99 +/- 113.09] pg/ml) (all P < 0.01), while the contents of plasma beta endorphin in groups A ([212.70 +/- 29.49] pg/ml), B ([157.99 +/- 24.01] pg/ml), and C ([180.81 +/- 20.20] pg/ml) were remarkably lower than that in the control ([274.73 +/- 27.64] pg/ml) (all P < 0.01). CONCLUSION: In the plasma of CPPS patients, the content of substance p is significantly elevated and that of beta endorphin markedly reduced, which suggests that they may be involved in the inflammatory reaction of CPPS. The levels of plasma substance p and beta endorphin can be used as valuable reference for the TCM classification of chronic prostatitis.

Treatment of chronic prostatitis/chronic pelvic pain syndrome category IIIA with Serenoa repens plus selenium and lycopene (Profluss) versus S. repens alone: an Italian randomized multicenter-controlled study.

OBJECTIVES: To evaluate the efficacy and safety of Serenoa repens + selenium and lycopene (Profluss) versus S. repens alone for the treatment of category IIIa chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). PATIENTS AND METHODS: 102 patients with IIIa CP/CPPS were enrolled and randomized into two groups each to receive Profluss or S. repens alone for 8 weeks. Evaluation was based on results of the National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI), IPSS, maximum peak flow rate (MPFR), and PSA measurements at baseline and at weeks 4, 8 and 8 after the end of treatment. The primary endpoint was a >50% reduction in NIH-CPSI score. Secondary endpoints evaluated were MPFR, IPSS, PSA and white blood cell count. RESULTS: No patients withdrew from the study. The mean NIH-CPSI score decreased significantly (p < 0.001) in both groups; we observed a decrease in the total score from 27.45 to 13.27 in group 1 (-51.64%) and from 27.76 to 20.62 in group 2 (-26.06%). IPSS improved significantly (p < 0.001) in both arms, but more in group 1. PSA and white blood cell count decreased significantly (p < 0.007) only in group 1. The MPFR improved more in group 1 (p < 0.005). CONCLUSION: Profluss is a triple therapy that is safe and well tolerated. It ameliorates symptoms associated with IIIa CP/CPPS.

Relaxin is not related to symptom-giving pelvic girdle relaxation in pregnant women.

BACKGROUND: The pregnancy associated hormone relaxin induces loosening of the pelvic ligaments in several species. This study was undertaken to evaluate whether pregnant women with symptom-giving girdle relaxation had increased serum relaxin concentrations during pregnancy. METHOD: Serum relaxin concentrations were measured in 38 pregnant women with symptom-giving pelvic girdle relaxation at the time of diagnosis, in the 30th and 38th week of pregnancy as well as 2 and 6 months after delivery. Fourteen pregnant women without symptoms served as a control group. Relaxin concentrations were measured by a homologous enzyme linked immuno-sorbent assay. All participants were clinically examined including tests for symptom-giving pelvic girdle relaxation. RESULTS: No differences in serum relaxin concentrations were found throughout pregnancy and after delivery. CONCLUSION: The present results do not suggest an important role for relaxin in symptom-giving pelvic girdle relaxation during human pregnancy.

[Effect of nei-yi recipe on plasma beta-endorphin levels during menstrual cycle in women with endometriosis].

In order to investigate the mechanism of Nei-Yi Recipe (NYR) in treatment of endometriosis, we observe the changes of plasma beta-endorphin concentrations in women with endometriosis treated by NYR. It was found that in luteal phase beta-endorphin concentrations in plasma were significantly reduced in moderate and severe dysmenorrhea groups compared with mild and control groups. Moreover, beta-endorphin level in severe dysmenorrhea group was lower in the luteal phase than that in the follicular phase, and it was lower in patients with pelvic pain than that without pelvic pain. In normal women, the contents of beta-endorphin in plasma were not changed during menstrual cycle. It was also found that plasma beta-endorphin levels were significantly increased in luteal phase and follicular phase after treatment by NYR. The therapeutical mechanism of NYR on dysmenorrhea and pelvic pain and enhancement of immune function might be mediated by increase of plasma beta-endorphin levels.
