Anti-Müllerian hormone level may predict successful pregnancy after adenomyomectomy in patients with infertility due to adenomyosis.

ABSTRACT: We aimed to determine clinical factors predicting successful pregnancy by comparing pregnancy failure and success groups after adenomyomectomy. Additionally, we analyzed fertility outcomes after adenomyomectomy.The medical records of 43 patients who had undergone adenomyomectomy and received in vitro fertilization treatment from 2017 to 2020 were retrospectively reviewed. Patients were divided into pregnancy failure (n = 28) and pregnancy success (n = 15) groups. Patients' demographic factors were evaluated and compared between the groups.The age of patients was higher (39.0 [32.0-45.0] vs. 37.0 [33.0-42.0] years, P = .006) whereas the level of anti-Müllerian hormone (anti-Müllerian hormone [AMH]; 0.54 [0.01-8.54] vs. 2.91 [0.34-7.92] ng/mL, P = .002) lower in the pregnancy failure group compared to the pregnancy success group. The operative time was longer (220.0 [68.0-440.0] vs. 175.0 [65.0-305.0] min, P = .048) while the estimated blood loss higher (750 [100-2500] vs. 500 [50-2000] mL, P = .016) in the pregnancy failure group compared to the pregnancy success group. No significant difference was observed in body mass index, symptoms, cancer antigen 125, preoperative uterine volume, or type of adenomyosis. In the multivariate analysis, age and AMH were significant predictive factors for successful pregnancy.Ovarian reserve (age and AMH) and disease severity might be predictive factors for successful pregnancy in patients who have undergone adenomyomectomy. Adenomyomectomy should be considered for women desiring pregnancy and having appropriate ovarian reserve. Our results would be beneficial for patients and clinicians before deciding on adenomyomectomy. Larger prospective studies are required to confirm our findings.

Adenomyosis is associated with specific proton nuclear magnetic resonance (1H-NMR) serum metabolic profiles.

OBJECTIVE: To determine whether the adenomyosis phenotype affects the proton nuclear magnetic resonance (1H-NMR)-based serum metabolic profile of patients. DESIGN: Cohort study. SETTING: University hospital-based research center. PATIENTS: Seventy-seven patients who underwent laparoscopy for a benign gynecologic condition. INTERVENTIONS: Pelvic magnetic resonance imaging and collection of a venous peripheral blood sample were performed during the preoperative workup. The women were allocated to the adenomyosis group (n = 32), or the control group (n = 45). The adenomyosis group was further subdivided into two groups: diffuse adenomyosis of the inner myometrium (n = 14) and focal adenomyosis of the outer myometrium (n = 18). Other adenomyosis phenotypes were excluded. MAIN OUTCOME MEASURES: Metabolomic profiling based on 1H-NMR spectroscopy in combination with statistical approaches. RESULTS: The serum metabolic profiles of the patients with adenomyosis indicated lower concentrations of 3-hydroxybutyrate, glutamate, and serine compared with controls. Conversely, the concentrations of proline, choline, citrate, 2-hydroxybutyrate, and creatinine were higher in the adenomyosis group. The focal adenomyosis of the outer myometrium and the diffuse adenomyosis phenotypes also each exhibited a specific metabolic profile. CONCLUSION: Serum metabolic changes were detected in women with features of adenomyosis compared with their disease-free counterparts, and a number of specific metabolic pathways appear to be engaged according to the adenomyosis phenotype. The metabolites with altered levels are particularly involved in immune activation as well as cell proliferation and cell migration. Nevertheless, this study did find evidence of a correlation between metabolite levels and symptoms thought to be related to adenomyosis. Further studies are required to determine the clinical significance of these differences in metabolic profiles.

[Changes of coagulation function in patients with adenomyosis and its clinical significance].

Objective: To measure the coagulation function of patients with adenomyosis so as to explore its relationship with increased menstrual amount and its clinical significance. Methods: From January 2014 to May 2019, clinical data of patients with hysterectomy in which 111 pathologically diagnosed adenomyosis (case group) and 115 with uterine myoma (control group) in Peking University First Hospital were retrospectively analyzed. The changes in coagulation function of the two groups were compared, and the correlation between coagulation and uterine volume in the adenomyosis group was analyzed. Results: (1) The activated partial thromboplastin time (APTT) was longer in the adenomyosis group than that in the uterine myoma group [(30.4±3.1), (29.6±2.5) s, respectively; P<0.05], while the thrombin time (TT) was shorter than that in the control group [(14.2±1.2), (14.6±1.0) s, respectively; P<0.05]. (2) According to the results of the Pearson correlation test, there was a positive correlation between prothrombin time (PT; r=0.135, P=0.042) and fibrinogen (FIB-C; r=0.139, P=0.036). (3) Platelet counts were higher in the anemia group of adenomyosis than that in the non-anemia group [(323±79)×109/L, (274±56)×109/L, respectively; P<0.05]. (4) FIB-C in non-anemia group of adenomyosis was lower than non-anemia group of uterine myoma [(2.8±0.5), (3.0±0.6) g/L, respectively; P<0.05], the anemia group of adenomyosis shortened TT compared with the anemia group of uterine myoma [(14.4±1.2), (15.2±0.9) s, respectively; P<0.05]. Conclusion: Patients with adenomyosis have abnormal coagulation function, which may be related to the increase amount of menstruation, and anemia may also be involved in coagulation disorders.

Expression of Lewis (b) blood group antigen interferes with oral dienogest therapy among women with adenomyosis.

Adenomyosis is frequently observed in premenopausal women, and oral dienogest is the recommended treatment to target the underlying pathology and improve the symptoms. This retrospective study investigated the association of Lewis (b) antigen expression with outcomes of dienogest therapy among women with adenomyosis. Records from a total of 342 adenomyosis patients were analysed, who were prescribed with oral dienogest for a maximum of 16 weeks. Expression levels of Lewis (b) antigen were measured to categorize all patients into either Le (b)- and Le(b)+ groups. Treatment outcomes, in terms of uterine volume, menstrual flow, pain symptoms and quality of life, were compared between the two groups. While oral dienogest therapy showed considerable clinical efficacy in both groups of patients, the extent of improvements in treatment outcomes was significantly more pronounced in Le (b)- group than Le (b)+ group, with respect to treatment time, uterine symptoms, menstrual flow, pain symptoms and quality of life. No difference in adverse effects was observed between the two groups. Expression of Lewis (b) blood group antigen interferes with oral dialogist therapy among women with adenomyosis.

Elasticity of adenomyosis is increased after GnRHa therapy and is associated with spontaneous pregnancy in infertile patents.

OBJECTIVE: To explore the effects of GnRHa on adenomyosis by transvaginal elastography. METHODS: A prospective observational study included patients who were diagnosed as adenomyosis by conventional transvaginal ultrasound and infertility. The sonographic characters of elastography, the degree of dysmenorrhea and the values of serum CA125 before and following GnRHa (Triptorelin 3.75 mg were administered every 28 days) plus add-back therapy were reviewed and analyzed. Each case had a 6 months follow up and the information of pregnancy were recorded. RESULTS: 45 patients who completed the 6 months follow-up were included in the analysis. Twelve cases (group 1) were pregnancy during the follow-up and the other thirty-three cases (group 2) failed their attempts. The numerical rating scale and CA125 of all the cases were both significantly reduced 6 months after therapy. All of enlarged uterus decreased to accessible normal size. In group 1, the mean elasticity score was significantly higher for the uterine after therapy than before (3.6 ± 0.3 vs 2.3 ± 0.5, p = 0.004). In group 2, the mean elasticity score did not change for the uterine after therapy than before (2.2 ± 0.5 vs 2.5 ± 0.6, p = 0.77). CONCLUSION: Elasticity of adenomyosis is increased after GnRHa therapy. And the higher elasticity of adenomyosis after GnRHa therapy is associated with spontaneous pregnancy in infertile patents.

The Disease Phenotype of Adenomyosis-Affected Women Correlates With Specific Serum Cytokine Profiles.

BACKGROUND: Adenomyosis (ADE) is an enigmatic uterine disorder. Several types have been previously described: diffuse adenomyosis (DIF-ADE), focal adenomyosis (FOC-ADE), and association of focal and diffuse lesions (FOC/DIF-ADE). Abnormal immune phenomena have been described that may provide an understanding of the pathophysiology of adenomyosis. However, the immune imbalance in adenomyosis is however still poorly understood. OBJECTIVE: To compare serum cytokine profiles for the various adenomyosis phenotypes in adenomyosis versus disease-free women. MATERIALS AND METHODS: This cohort study included 80 women. Based on the magnetic resonance imaging (MRI) findings, the women were allocated to the ADE group (n = 60) and the control group (n = 20). The ADE group was further subdivided according to the phenotype: DIF-ADE, FOC-ADE, and FOC/DIF-ADE. For all of the women, serum cytokine levels were assayed by multiplex immunoassay. RESULTS: Serum levels of interleukin (IL) 23 (237.77 pg/mL ± 70.97 in the ADE-group versus 1855.04 ± 1411.33 in the control group, P = .019), IL25 (31.98 ± 8.54 vs 222.08 ± 170.90, respectively, P = .006), IL31 (10.13 ± 3.83 vs 91.51 ± 71.21, respectively, P = .034), IL33 (3.77 ± 1.23 vs 17.86 ± 11.49, respectively, P = .016), and IL17F (16.29 ± 2.35 vs 30.12 ± 8.29, respectively, P = .042) were significantly lower in the women with adenomyosis when compared to the controls In the FOC/DIF-ADE group, the serum levels of IL23, IL31, IL25, and IL33 were significantly lower when compared to the control group. CONCLUSION: Serum levels of IL23, IL31, IL25, and IL33 were lower in women exhibiting adenomyosis forms with associated diffuse and focal lesions when compared with controls. The pathogenesis of adenomyosis may be associated with an immunotolerant process that is more pronounced in associated FOC/DIF-ADE.

Predisposing factors for predicting the therapeutic response of adenomyosis after uterine artery embolization: serum CA125 levels and accompanying endometriosis.

PURPOSE: We aimed to identify predisposing factors that could help predict the therapeutic response of adenomyosis after uterine artery embolization (UAE). METHODS: This was a retrospective, single-center study of patients admitted to the hospital for adenomyosis between 2013 and 2015. Sixty-eight patients with adenomyosis who underwent UAE with tris-acryl gelatin microspheres were divided into two groups based on their therapeutic response (complete or incomplete necrosis of lesions), and pre- and postprocedural pelvic magnetic resonance imaging (MRI) data. Patients were followed up for 12 months after UAE. Improvements in dysmenorrhea and menorrhagia were evaluated based on the symptom relief criteria. Improvement rates in both groups were analyzed and compared. Multivariate logistic regression analysis was used to identify the predisposing factors from retrospectively gathered baseline data that might affect the therapeutic response, including MRI features, clinical symptoms, biochemical index, and accompanying diseases of adenomyosis. Then, a prognostic model was established, and the receiver operating characteristic (ROC) curve of identified factors was drawn to determine their predictive value. RESULTS: Following UAE, 46 patients (67.6%) showed complete necrosis, while 22 patients (32.4%) showed incomplete necrosis. At 12-month follow-up, dysmenorrhea symptom improvement was seen in 94.7% of complete necrosis and 50% of incomplete necrosis group (P < 0.001); menorrhagia symptom improvement was seen in 96.2% of complete necrosis and 57.1% of incomplete necrosis groups (P = 0.004). Multivariate logistic regression analysis determined serum cancer antigen 125 (CA125) levels (odds ratio [OR], 1.006; 95% confidence interval [CI], 1.002-1.010; P = 0.005) and accompanying endometriosis (OR, 6.869; 95% CI, 1.881-25.016; P = 0.004) as predisposing factors. The areas under the ROC curve of CA125, endometriosis, and these two indicators combined were 0.785, 0.708, and 0.845, which corresponded to sensitivities of 95.5%, 66.7%, and 68.2% and specificities of 52.2%, 80.0%, and 87.0% at optimal cutoff values, respectively. CONCLUSION: Symptom relief of dysmenorrhea and menorrhagia for patients with complete necrosis was significantly better than that for patients with incomplete necrosis. Serum CA125 levels and accompanying endometriosis can effectively distinguish complete necrosis from incomplete necrosis.

Cerebral Infarcts by Nonbacterial Thrombotic Endocarditis Associated with Adenomyosis: A Case Report.

We report a case of multiple embolic cerebral infarcts associated with nonbacterial thrombotic endocarditis (NBTE) in a patient with adenomyosis. The patient presented with dysarthria, left perioral sensory change, and left-hand weakness. Magnetic resonance imaging revealed multiple vascular territory infarctions involving the bilateral cerebellum and the right precentral gyrus. Magnetic resonance angiography was normal. d-Dimer, carbohydrate antigen (CA) 19-9, and CA125 levels were elevated. Abdominal and pelvic computed tomography with iodine contrast enhancement revealed a huge adenomyosis with left ovarian cyst. Transesophageal echocardiography (TEE) with agitated saline injection test demonstrated shaggy vegetation at the coapting edge of both mitral leaflets and mitral regurgitation. A diagnosis of NBTE was established and treatment with anticoagulation was initiated. Two weeks later, the thrombi reduced significantly on follow-up TEE and transthoracic echocardiography. The patient underwent an abdominal hysterectomy with bilateral salpingo-oophorectomy, and pathological specimens confirmed adenomyosis. The possibility that adenomyosis can be associated with NBTE suggests one of the underlying thromboembolic mechanisms in adenomyosis. Clinicians should be aware of the potential thromboembolic risk of adenomyosis. Further reporting of similar cases is needed to confirm the thromboembolic mechanism.

Nonbacterial Thrombotic Endocarditis Complicated by Cerebral Infarction in a Patient with Adenomyosis with High Serum CA125 Level; A Case Report.

We report a case of a 48-year-old woman with multiple cerebral infarctions caused by nonbacterial thrombotic endocarditis (NBTE) because of adenomyosis with high serum carbohydrate antigen (CA)125 level. Transesophageal echocardiography (TEE) showed a vegetation, 4 mm in diameter, adjacent to the anterior leaflet of the mitral valve on day 2. Soluble CA125 level was elevated to 901 U/mL. Intravenous infusion of unfractionated heparin sodium was started. On day 35, TEE revealed reduction of the vegetation in size, 2 mm in diameter. On day 38, she was transferred to the hospital for further rehabilitation. CA125 is a transmembrane mucin that contributes to the progression of epithelial ovarian cancer. It is important to keep in mind that adenomyosis with abnormally high serum CA125 level may be at high risk of NBTE.

Elevated plasma levels of lysophosphatidic acid and aberrant expression of lysophosphatidic acid receptors in adenomyosis.

BACKGROUND: Given the important roles of the receptor-mediated lysophosphatidic acid (LPA) signaling in both reproductive tract function and gynecological cancers, it will be informative to investigate the potential role of LPA in the development of adenomyosis. The objective of this study was to evaluate the levels of LPA in plasma and the expression of six LPA receptors in the endometrial tissue collected from women with and without adenomyosis. METHODS: Plasma and endometrial tissue samples were collected form women with and without adenomyosis. The levels of LPA in plasma were determined by using high-performance liquid chromatography electrospray ionization tandem mass spectrometry (HPLC-ESI-MS/MS). Immunohistochemistry was performed to evaluate the expression of six LPA receptors (LPA1-6) in endometrial tissue samples. The effects of LPA on IL-8 production, VEGF production and cell proliferation in human endometrial stromal cells (ESCs) were also assessed. RESULTS: LPA1 staining was localized to the cytoplasm, membrances of the epithelial cells of the endometrial glands, and there was little staining in the stromal cells. LPA2-5 staining were localized to the nuclei of stromal and glandular cells. Plasma levels of LPA were increased in adenomyosis. LPA1, LPA4 and LPA5 immunoreactivity were significantly higher in the adenomyosis group than in the control group, while LPA2 and LPA3 immunoreactivity were significantly lower in the adenomyosis group than in the control group. LPA6 was undetectable in the endometria. LPA induced the release of IL-8 from ESCs but did not affect cell proliferation and VEGF production. CONCLUSION: These results indicate that elevated plasma levels of LPA and aberrant expression of LPA receptors in the endometria may be associated with the development of adenomyosis.

Gonadotrophin-releasing hormone agonist combined with high-intensity focused ultrasound ablation for adenomyosis: a clinical study.

OBJECTIVES: This study was to investigate the clinical efficacy of a gonadotrophin-releasing hormone agonist (GnRH-a) combined with high-intensity focused ultrasound (HIFU) ablation treatment for adenomyosis. DESIGN: A non-randomized prospective study. SETTING: Gynaecological Minimally Invasive Centre in a single hospital. POPULATION: Patients with adenomyosis. METHODS: Seventy-nine patients with adenomyosis were enrolled, including 55 patients in the control group treated with only HIFU and 24 patients in the study group treated with GnRH-a combined with HIFU. All the patients follow up 6 months after the HIFU procedure. The related parameters in the two groups were assessed before and 3 months as well as 6 months after treatment including serum levels of tumor marker and cytokine, volumes of uterine, adenomyotic lesion, and menstrual blood, as well as dysmenorrheal scores. MAIN OUTCOME MEASURES: Differences between the group treated with HIFU alone and the group treated with GnRH-a combined with HIFU. RESULTS: Before HIFU treatment, no significant difference was observed in serum levels of CA125, CA19-9, and interleukin-6 (IL-6), the volumes of uterine, adenomyotic lesion, and menstrual blood, as well as dysmenorrhea scores between the two groups. (P > 0.05). The serum CA125 levels significantly decreased in both groups after HIFU, but the serum CA125 levels in the study group were still significantly lower than those in the control group (P < 0.05). The volume of uterine and adenomyotic lesion significantly decreased in both groups after HIFU procedure, and decreased even more in the study group 3 and 6 months after treatment (P < 0.05). Dysmenorrhea scores and menstruation volumes significantly decreased in both groups after HIFU treatment. Moreover in the study group were significantly lower than those in the control group after 3 and 6 months (P < 0.05). No significant difference was observed in the rate of adverse effects between the two groups. CONCLUSIONS: The short-term follow-up results indicate that the combination of GnRH-a and HIFU treatment significantly decreased serum CA125 levels, volumes of uterine, adenomyotic lesion and menstrual blood, as well as dysmenorrhea scores, and improved the clinical outcomes compared with the HIFU ablation alone in patients with adenomyosis. However, the further follow-up is needed to explore the long-term effects. TWEETABLE ABSTRACT: A combination of GnRH-a with HIFU in the treatment of adenomyosis significantly decreased serum CA125 levels, uterine and adenomyotic lesion volumes, dysmenorrhea scores, and menstrual blood volumes.

Changes in anti-müllerian hormone levels as a biomarker for ovarian reserve after ultrasound-guided high-intensity focused ultrasound treatment of adenomyosis and uterine fibroid.

OBJECTIVE: To assess the changes in antimüllerian hormone (AMH) levels after ablation for symptomatic uterine fibroids and adenomyosis using ultrasound-guided high-intensity focused ultrasound (USgHIFU). DESIGN: A prospective study. SETTING: Gynaecological department in multiple hospitals in South Korea. POPULATION: Patients with uterus fibroids and adenomyosis. METHODS: Seventy-nine women with symptomatic uterine fibroids and adenomyosis who met the inclusion criteria were enrolled in our study between January 2014 and December 2014. All patients underwent USgHIFU ablations. Each patient was examined before and after treatment, and at 6 and 12 months after treatment by T2-weighted MRI imaging (T2WI) and T1-weighted MRI imaging (T1WI) with gadolinium injection. Symptom severity scores (SSS), Uterine Fibroid Symptom Quality of Life (UFS-QOL) questionnaire subscales, and reductions of treated volume were assessed. AMH levels before and 6 months after HIFU ablation were compared to determine whether USgHIFU ablation affected ovarian reserve. MAIN OUTCOME MEASURES: HIFU treatment did not affect the ovarian function. RESULTS: HIFU treatment time (mean ± standard deviation), HIFU ablation time, and treatment energy were 73.5 ± 25.6 minutes, 9994.7 ± 386.8 seconds, and 364 713.8 ± 156 350.7 Joules, respectively. AMH levels before and 6 months after HIFU ablation were 2.11 ± 2.66 and 1.84 ± 2.57 µg/l, respectively. There was no significant difference in AMH level between the two time points (P > 0.05). CONCLUSIONS: USgHIFU ablation for uterine fibroid and adenomyosis was effective without affecting ovarian reserve. TWEETABLE ABSTRACT: HIFU ablation is a safe and effective treatment for patients with uterine fibroids and adenomyosis that does not affect ovarian function.

CA125 modified by PLT and NLR improves the predictive accuracy of adenomyosis-derived pelvic dense adhesion.

To explore the value of serum levels of CA125, platelet count (PLT), neutrophil-lymphocyte ratio (NLR), and modified CA125 markers CA125a and CA125b in predicting pelvic dense adhesion (PDA) associated with adenomyosis, CA125a = lg(CA125 × PLT × 10), CA125b = lg(CA125 × NLR).This retrospective study included 304 patients who underwent surgery for adenomyosis. Correlations of serum levels of CA125, PLT, NLR, and modified CA125 markers with adenomyosis-derived PDA were analyzed by Logistic regression. Receiver operating characteristic curve was applied to assess the utility of these parameters for predicting PDA.All the parameters including CA125, PLT, NLR, and modified CA125 markers were positively correlated with PDA (P < .05 or P < .01). More importantly, CA125a was more specific (85.03% vs. 83.00%) and more sensitive (47.56% vs. 47.47%) than CA125 alone for the prediction of PDA, and CA125b could also improve the predictive specificity of PDA (53.13% vs. 47.47%).Serum CA125, PLT, and NLR were all closely correlated with PDA in adenomyosis patients. CA125 modified by PLT and NLR could further improve the predictive accuracy of adenomyosis-derived PDA, thus providing more meaningful references for better-informed decisions about the mode of surgical access for the clinical treatment of adenomyosis.

Serum Osteopontin Levels Are Decreased in Focal Adenomyosis.

We investigated whether serum osteopontin (OPN) levels are different according to specific phenotypes of adenomyosis and endometriosis. We conducted a prospective laboratory study in a university referral center for endometriosis between May 2005 and May 2013 and included 148 nonpregnant women, younger than 42 years, undergoing surgery for a benign gynecological condition and who had a preoperative pelvic magnetic resonance imaging (MRI). The presence of focal and/or diffuse adenomyosis was determined by pelvic MRI, and women were classified into 3 groups: no-adenomyosis (No-AM), isolated diffuse adenomyosis (DIF-AM), and focal adenomyosis with or without diffuse adenomyosis (FOC-AM). After complete surgical exploration of the pelvic cavity, the presence and type of endometriosis was surgically determined and histologically confirmed. We distinguished 4 phenotypes: no endometriosis, superficial peritoneal endometriosis (SUP), ovarian endometrioma, and deep infiltrating endometriosis (DIE). Osteopontin levels were measured by enzyme-linked immunosorbent assay in serum samples obtained in all participants in the month preceding surgery. Our results show lower OPN levels in women with focal adenomyosis compared to adenomyosis-free controls. Our results also show a decrease in OPN levels in women with associated DIE and focal adenomyosis compared to women with SUP. Various serum biomarkers have been studied in the context of endometriosis severity and subtypes, whereas data on serum markers of adenomyosis are scarce. Both entities are often associated, and adenomyosis could be a confounding factor influencing results. Future research on serum biomarkers should describe subtypes of adenomyosis and endometriosis and analyze results according to well-defined subtypes.

Multiple Cerebral Infarctions in a Patient with Adenomyosis on Hormone Replacement Therapy: A Case Report.

A 59-year-old woman was admitted to our hospital because of repeated episodes of bilateral hand weakness. She had a 10-year history of combined estrogen-progestin therapy for menopausal symptoms. Magnetic resonance imaging on admission showed multiple hyperintense lesions in bilateral cerebral and cerebellar cortices on diffusion-weighted imaging. Transesophageal echocardiography showed thrombus formation on the aortic valve and moderate aortic insufficiency. Laboratory test demonstrated elevated CA125 (334.8 U/mL) and D-dimer (7.0 µg/mL) levels. Trousseau's syndrome (cancer-related hypercoagulation) was considered, but various examinations showed only uterine adenomyosis and no evidence of cancer. Multiple cerebral infarctions were considered to be caused by Trousseau's syndrome-like condition associated with uterine adenomyosis. CA125 and coagulation markers should be measured in adenomyosis patients treated with hormone replacement therapy, because a mucinous tumor and coagulation markers may be good markers for the risk of thromboembolism in such patients.

Dysfunctional coagulation and fibrinolysis systems due to adenomyosis is a possible cause of thrombosis and menorrhagia.

OBJECTIVE: To study the effects of adenomyosis on the coagulation and fibrinolysis system during menstruation and the relationship between dysfunction of the coagulation and fibrinolysis system and the symptoms and complications of adenomyosis. STUDY DESIGN: Concentrations of thrombin-antithrombin complex (TAT) and soluble fibrin (SF) as markers of coagulation, D-dimer (DD) as a marker of both coagulation and fibrinolysis, and plasmin-alpha 2-plasmin inhibitor complex (PIC) as a marker of fibrinolysis in the peripheral blood of eight patients with adenomyosis were measured daily from the first to fifth day of menstruation. Associations between levels of these markers during menstruation and patient characteristics, history of thrombotic disorder, and hemoglobin loss during menstruation were investigated. RESULTS: TAT, SF, DD and PIC increased in 5, 2, 3 and 1 of the 8 patients, respectively. TAT increased in 5 of the 6 patients with an adenomyotic uterus ≥100 cubic centimeters. Patients with elevated DD, SF and/or PIC were among patients with elevated TAT. DD was only increased in 3 patients with a past history of small cerebral infarction or pulmonary thromboembolism and/or hemoglobin loss >2.0g/dl during menstruation. SF was increased only in 2 patients with a past history of cerebral infarction or pulmonary thromboembolism. PIC increased in 1 of the 2 patients with hemoglobin loss >2.0g/dl during menstruation. CONCLUSION: Adenomyosis patients with a uterus volume ≥100 cubic centimeters are at risk of having an activated coagulation system. These patients, particularly those with elevated SF and DD, may be at risk of thrombotic disorders. Fibrinolysis is activated in a portion of patients with activated coagulation during menstruation. Activated fibrinolysis during menstruation may contribute to menorrhagia in patients with adenomyosis, as only patients with activated fibrinolysis suffered menorrhagia, even though patients with an adenomyotic uterus ≥100 cubic centimeters without activated fibrinolysis did not. These results suggest extensive adenomyosis confers a potential risk of infarction and thrombosis and exacerbates menorrhagia via activation of coagulation and fibrinolysis during menstruation.

Ultrasound-guided percutaneous microwave ablation for adenomyosis: efficacy of treatment and effect on ovarian function.

A total of 142 premenopausal women with symptomatic adenomyosis underwent ultrasound (US)-guided percutaneous microwave ablation (PMWA) at the Chinese PLA General Hospital. This study aimed to evaluate changes in serum pituitary, gonadal hormone and cancer antigen 125 (CA125) levels after US-guided PMWA. Therefore, estradiol (E2), follicle-stimulating hormone (FSH), prolactin (PRL) and CA125 levels were evaluated before ablation and at 3, 6, 9 and 12 months after ablation. No significant differences were observed in the E2 and FSH levels pre-ablation and during follow-up (E2: p=0.933, p=0.987, p=0.106, p=0.936; FSH: p=0.552, p=0.295, p=0.414, p=0.760). The mean absolute values of serum CA125 and PRL were significantly decreased at 3, 6, 9 and 12 months after ablation (CA125: p<0.001, p<0.001, p<0.001, p=0.003; PRL: p<0.001, p<0.001, p<0.001, p<0.001). A significant correlation between changes in CA125 levels and uterine volume was found (p<0.001). No evidence of a decline in ovarian function was observed after US-guided PMWA.

Usefulness of CA125 in the differential diagnosis of uterine adenomyosis and myoma.

OBJECTIVES: To evaluate the usefulness of CA125 levels in the differential diagnosis of adenomyosis and myoma. This has been addressed by few, if any, previous studies. STUDY DESIGN: Preoperative serum CA125 levels were measured in 2149 women who were diagnosed at total hysterectomy as having adenomyosis, myoma, endometriosis, and/or normal pelvis. Their medical records were retrieved and reviewed. RESULTS: The mean serum CA125 level in the adenomyosis patients was significantly greater than that in the patients diagnosed with myoma (65.21±96.60 U/mL vs.12.86±14.23 U/mL, respectively; P<0.001). In the differential diagnosis of adenomyosis and myoma, the cut-off serum CA125 level with the highest accuracy (78.8%) and highest diagnostic value (61.2%) was 19 U/mL. Using this cut-off value, the negative predictive value was 69.5%, and the positive predictive value was 76.5%. These results are clearly superior to those of the empirical single cut-off value of 35 U/mL. Receiver operating characteristic curve analysis revealed the area under the curve for differentiating adenomyosis from myoma was 0.776, indicating good diagnostic performance. CONCLUSION: In the differential diagnosis of adenomyosis and myoma, cut-off values for CA125, particularly the cut-off value of 19 U/mL, provide improved diagnostic performance. Serum CA125 testing can be performed during the initial screening of women with possible adenomyosis to differentiate this condition from myoma, although the diagnostic accuracy of using CA125 testing alone is limited.

Serum differential proteomic analysis of endometriosis and adenomyosis by iTRAQ technique.

OBJECTIVE(S): Adenomyosis and endometriosis are two different diseases, although they have similar pathogenesis and characteristic. The serum differential expressed proteins in adenomyosis and endometriosis may result from the different pathogenesis of two diseases. Proteomic technology is a useful method for detecting all the proteins in samples. We try to use isobaric tags for relative and absolute quantitation (iTRAQ) technology to explore the association between the potential pathogenesis of these two diseases and these identified proteins. STUDY DESIGN: The serum samples from 20 patients with adenomyosis and from 20 patients with endometriosis were analyzed using iTRAQ technology to detect the differential expression of proteins. The validation of the proteins was performed using Western blot. RESULTS: In the serum of women with adenomyosis and with endometriosis, 14 proteins were found differentially expressed using iTRAQ technology. Nine proteins were high-expression in adenomyosis group and four proteins increased in endometriosis group. And the differential expression proteins were validated by Western blot. CONCLUSION(S): The proteins increased in adenomyosis group are related to blood coagulation and complement activation effects, and the proteins high-expression in endometriosis mainly take part in the process of inflammatory response and regulation of apoptosis. The differentially expressed proteins in two groups may due to the different pathogenesis of two diseases.

The disturbance of TH17-Treg cell balance in adenomyosis.

OBJECTIVE: To investigate the balance between regulatory T cells (Treg) and T-helper 17 cells (T(H)17) in peripheral blood and uteri of women with adenomyosis (AM), and to evaluate their potential correlation with dysmenorrhea and CA-125 levels. DESIGN: Laboratory study using human peripheral blood and tissues. SETTING: Academic hospital. PATIENT(S): Forty-five patients with AM (study group) and 25 women without AM (control group). INTERVENTION(S): The peripheral blood and tissues harvested from all groups were subjected to flow cytometry, ELISA, quantitative real-time polymerase chain reaction, and immunohistochemistry. The severity of dysmenorrhea was distinguished by visual analog scale (VAS). MAIN OUTCOME MEASURE(S): T(H)17 and Treg cell frequency, mRNA and protein levels of transcription factors and cytokines in all groups, and their correlation between the T(H)17-Treg ratio and dysmenorrhea severity or CA-125 level. RESULT(S): The disturbance of T(H)17-Treg balance was demonstrated in peripheral circulation and uteri of patients with both diffuse and focal AM, and it correlated positively with dysmenorrhea severity and CA-125. CONCLUSION(S): The findings suggest that T(H)17-Treg imbalance may play a crucial role in the immunopathogenesis of AM, and may be thus a potential target of AM therapy.
