RESUMO

BACKGROUND: Diminished ovarian reserve (DOR) is one of the obstacles affecting the reproductive outcomes of patients receiving assisted reproductive therapy. The purpose of this study was to investigate whether dual trigger, including gonadotropin-releasing hormone agonist (GnRHa) and human chorionic gonadotropin (hCG), can improve pregnancy outcomes in patients with DOR undergoing in vitro fertilization (IVF) cycles using mild stimulation protocols. METHODS: A total of 734 patients with DOR were included in this retrospective study. Patients were divided into a recombinant hCG trigger group and a dual trigger group (hCG combined with GnRHa) according to the different trigger drugs used. The main outcome measures included the number of oocytes retrieved, the fertilization rate, the number of transferable embryos, the implantation rate, the clinical pregnancy rate, the miscarriage rate, the live birth rate (LBR), and the cumulative live birth rate (CLBR). Generalized linear model and logistic regression analyses were performed for confounding factors. RESULTS: There were 337 cycles with a single hCG trigger and 397 cycles with dual trigger. The dual trigger group demonstrated significantly higher numbers of retrieved oocytes [3.60 vs. 2.39, adjusted ß = 0.538 (0.221-0.855)], fertilized oocytes [2.55 vs. 1.94, adjusted ß = 0.277 (0.031-0.523)] and transferable embryos [1.22 vs. 0.95, adjusted ß = 0.162 (-0.005-0.329)] than did the hCG trigger group, whereas no significant difference in the fertilization rate was observed between the two groups. Moreover, the embryo transfer cancellation rate (35.5% vs. 43.9%) was obviously lower in the dual trigger group. Among the fresh embryo transfer cycles, the implantation rate, clinical pregnancy rate, miscarriage rate and live birth rate were similar between the two groups. After controlling for potential confounding variables, the trigger method was identified as an independent factor affecting the number of oocytes retrieved but had no significant impact on the CLBR. CONCLUSIONS: Dual triggering of final oocyte maturation with hCG combined with GnRHa can significantly increase the number of oocytes retrieved in patients with DOR but has no improvement effect on the implantation rate, clinical pregnancy rate or LBR of fresh cycles or on the CLBR.

RESUMO

Premature ovarian failure (POF) is a complication of ovarian dysfunction resulting from the depletion or dysfunction of primordial follicles (PFs) in the ovaries. However, residual follicles that have the potential to be activated are present in POF or aged women. Little is known about the mechanisms by which the remaining dormant PFs in POF patients are activated. Using mass spectrometry, we screened differentially generated peptides extracted from the ovarian cortical tissue biopsies of patients with or without POF, during which we identified PFAP1, a peptide that significantly promoted the activation of PFs in the ovaries of 3 dpp mice in vitro. PFAP1 reversed age-related fertility damage in vivo to a certain extent, promoted estrogen (E2) and anti-mullerian hormone (AMH) production (p < .05), and decreased the levels of follicle-stimulating hormone (FSH) (p < .05). In newborn mouse ovaries, PFAP1 could bind to the protein minichromosome maintenance protein 5 (MCM5) and inhibit its ubiquitination and degradation. In addition, PFAP1 promoted the proliferation of GCs, probably by regulating the function and production of MCM5. In conclusion, PFAP1 could promote the activation of PFs in the ovaries of newborn mice, partially restore the ovarian function of aged mice, and increase the proliferation of primary granulosa cells (GCs) by regulating the function of MCM5. PFAP1 is a promising novel peptide that may be developed into a new therapeutic agent for POF and other ovarian diseases.

RESUMO

OBJECTIVE: To evaluate the effect of hormonal suppression of endometriosis on the size of endometriotic ovarian cysts. DATA SOURCES: The authors searched MEDLINE, PubMed, Cochrane Central Register of Controlled Trials, Embase, and ClinicalTrials.gov from January 2012 to December 2022. METHODS OF STUDY SELECTION: We included studies of premenopausal women undergoing hormonal treatment of endometriosis for ≥3 months. The authors excluded studies involving surgical intervention in the follow-up period and those using hormones to prevent endometrioma recurrence after endometriosis surgery. Risk of bias was assessed with the Newcastle-Ottawa Scale and Cochrane Risk of Bias Tool. The protocol was registered in PROSPERO (CRD42022385612). TABULATION, INTEGRATION, AND RESULTS: The primary outcome was the mean change in endometrioma volume, expressed as a percentage, from baseline to at least 6 months. Secondary outcomes were the change in volume at 3 months and analyses by class of hormonal therapy. The authors included 16 studies (15 cohort studies, 1 randomized controlled trial) of 888 patients treated with dienogest (7 studies), other progestins (4), combined hormonal contraceptives (2), and other suppressive therapy (3). Globally, the decrease in endometrioma volume became statistically significant at 6 months with a mean reduction of 55% (95% confidence interval, -40 to -71; 18 treatment groups; 730 patients; p <.001; I2 = 96%). The reduction was the greatest with dienogest and norethindrone acetate plus letrozole, followed by relugolix and leuprolide acetate. The volume reduction was not statistically significant with combined hormonal contraceptives or other progestins. There was high heterogeneity, and studies were at risk of selection bias. CONCLUSION: Hormonal suppression can substantially reduce endometrioma size, but there is uncertainty in the exact reduction patients may experience.

RESUMO

Objective: To observe the effects and safety of dienogest on the volume and symptoms of ovarian endometrioma (OMA). Methods: The clinical data of 75 patients with OMA who underwent treatment with dienogest (2 mg/day) at the First Affiliated Hospital of Nanjing Medical University from July 1st 2020 to March 31st 2024 were retrospectively analysed, mainly comparing the changes in the volume of OMA and the visual analogue scale (VAS) scores of endometriosis-related pain before and after the treatment, as well as observing the changes in the blood biological indicators, liver and kidney function, coagulation function and changes in breast. Results: The median cyst volumes of the OMA patients at 3, 6 and 12 months of dienogest treatment were 13.21 cm3 (volume reduction rate: 36.00%), 8.33 cm3 (volume reduction rate: 56.00%) and 4.10 cm3 (volume reduction rate: 77.62%), respectively, which were all significantly decreased from the pre-treatment period (all P<0.05). The VAS scores of pain of the OMA patients at 3, 6 and 12 months of dienogest treatment all were 0 mm. Blood cancer antigen 125 (CA125) and cancer antigen 19-9 (CA19-9) levels decreased progressively during treatment (all P<0.05). There were no statistical differences in the coagulation indexes, liver and kidney function indexes of the patients during dienogest treatment compared with those before treatment (all P>0.05). During the follow-up period, there were a few patients with changes in the growth sites or lesion category of the breast nodules, but there were no occurrence of breast cancer or precancerous lesions. Conclusion: Dienogest is effective in reducing OMA volume and alleviating endometriosis-related pain with few adverse effects.

RESUMO

Ovarian torsion can be defined as the bending of the ovaries on the supporting ligament, disrupting both venous and arterial blood circulation. Insufficient blood flow causes ovarian tissue hypoxia and leads to ischemia. This study aimed to investigate whether tocilizumab has a protective effect on ischemia-reperfusion injury due to ovarian torsion in rats. Eighteen female Wistar albino rats were divided into three equal groups (Sham (SG), ischemia-reperfusion (OIR), and ischemia-reperfusion+tocilizumab (OIRT)). Degeneration, necrosis, vascular dilatation/congestion, interstitial edema, hemorrhage, and polymorphonuclear lymphocyte (PMNL) infiltration scores were significantly different between the groups (p=0.001 for all parameters). Moreover, the OIRT group had a significant improvement in these criteria compared to the OIR group (p<0.05). Additionally, there was a considerable difference between OIRT and OIR groups in the number of primordial, developing, and atretic follicles groups (p<0.05), while there was no difference in the number of corpus luteum (p=0.052). Stress markers or cytokines, such as MDA, tGSH, NF-κB, TNF-α, IL-1ß, and IL-6, were significantly different between groups (p<0.05). Furthermore, a significant improvement was found in the measured variables when the OIRT group was compared with the OIR group (p<0.05). Tocilizumab may be an alternative option for treating ischemia-reperfusion injury due to ovarian torsion.

RESUMO

PURPOSE: We aimed to compare the results of image-guided drainage in addition to antibiotic therapy (antibiotherapy) with antibiotherapy alone in the treatment of tubo-ovarian abscesses (TOAs) and evaluate C-reactive protein (CRP) levels in predicting the success of antibiotherapy. METHODS: This was a retrospective study of 194 patients hospitalized with TOA. Patients were divided into the following two groups: those who underwent image-guided drainage in addition to parenteral antibiotherapy and those who did not undergo image-guided drainage and received antibiotherapy alone. CRP levels on the day of admission (day 0), day 4 of hospitalization (day 4), and day of discharge (last day) were recorded. The percentage of decrease in CRP levels during day 4 and the last day compared with that on day 0 was calculated. RESULTS: A total of 106 patients (54.6%) underwent image-guided drainage with antibiotherapy, whereas 88 patients (45.4%) did not undergo drainage and received antibiotherapy alone. At admission, the mean CRP level was 203.4 (± 96.7) mg/L and was similar in both groups. The mean decrease in the CRP level on day 4 compared with that on day 0 was 48.5% and was statistically higher in the group that underwent image-guided drainage. Antibiotherapy failed in 18 patients, and a statistically significant difference was observed between treatment failure and the rate of decrease in the CRP level on day 4 compared with that on day 0. According to the receiver operating characteristic (ROC) analysis, if the CRP level measured on day 4 decreased by < 37.1% compared with that on day 0, the probability of treatment failure would increase (area under the curve = 0.755; 95% confidence interval, 0.668-0.841; sensitivity, 73.6%; specificity, 60%). CONCLUSIONS: Image-guided drainage combined with antibiotherapy in the treatment of TOA has high success rates, lower recurrence rates, and lower surgical requirement, and the mean decrease in the CRP level on day 4 can be monitored at treatment follow-up. In patients receiving antibiotherapy alone, if the CRP level on day 4 decreases by < 37.1%, the treatment protocol should be changed.

RESUMO

OBJECTIVES: The aim of the study is to investigate the effects of Protocatechuic Acid (PCA), which is an antioxidant, anti-inflammatory and anti-apoptotic agent, on ovarian tissue and ovarian reserve against ischemia-reperfusion (IR) injury in a rat ovarian torsion model. BACKGROUND: Reactive oxygen radicals cause histopathological changes in the ovarian tissue during the reperfusion phase. PCA may have protective effects on ovarian tissue and reserve due to its antioxidant and antiapoptotic properties. METHODS: A total of 24 Wistar adult female rats were divided into 3 groups as the control (sham operation, n = 8), IR (Ischemia-Reperfusion, n = 8), and IR+PCA (Ischemia-Reperfusion + 80 mg/kg protocatechuic acid, n = 8). The IR and IR + PCA groups underwent 3 hours of ischemia followed by 3 hours of ovarian reperfusion. Protocatechuic acid (80 mg/kg) was administered to the IR+PCA group 30 minutes before reperfusion. After reperfusion, the ovaries were removed for histopathological and biochemical examination. RESULTS: Histopathological score and TUNEL+ cell count were significantly lower and AMH expression level was significantly higher in the IR+PCA group when compared to the IR group (p <0.05). However, in the comparison of the follicle counts, there was no statistically significant difference between all groups. Due to the increase in antioxidant activity, the MDA levels were found to be significantly lower in the IR+PCA group compared to the IR group (p < 0.05). CONCLUSION: Protocatechuic acid may be an effective antioxidant in protecting ovarian tissue and follicle reserve against IR injury of the ovary (Tab. 1, Fig. 4, Ref. 36).

RESUMO

STUDY OBJECTIVE: To assess the external validity of a recently published clinical risk score estimating the risk of failed medical treatment in patients with tubo-ovarian abscess (TOA) based on 4 clinical variables on admission. DESIGN: The probability of failed medical treatment predicted from the reference risk score was compared with the observed rates in a retrospective cohort of patients with TOA. Results were assessed using rigorous methods for clinical prediction models. SETTING: Safety-net teaching hospital system in Houston, Texas. PATIENTS: One hundred and sixty nine consecutive patients admitted with TOA between 2011 and 2018 were included. Some were treated conservatively with intravenous antibiotic agents; others required a drainage procedure. INTERVENTION: Electronic health records were reviewed and the 4 clinical predictors of failed conservative treatment were captured (age, white blood cell count on admission, abscess size, and presence of bilateral abscess). A clinical risk score was calculated for each patient. The prediction model was created using the risk score in a multivariate logistic regression. Then the calibration, discrimination, and accuracy of the model were evaluated to perform the external validation analysis. MEASUREMENTS AND MAIN RESULTS: Among 169 eligible patients, 50.2% were successfully treated with intravenous antibiotic agents and 49.8% needed abscess drainage. Patients undergoing drainage were more likely to be older, be diabetic, to present with elevated white blood cell count and fever, and to have a larger abscess size on univariate analysis. Among the 4 known predictors of drainage, abscess size was found to be the strongest. Significant difference in clinical characteristics was noted between our cohort and the reference cohort, and the model needed recalibration to adjust for these differences. The area under the receiver operating characteristic curve was 0.77 (0.71-0.84) indicating good discrimination. The Brier score was favorable (0.19) and the observed and predicted rates were similar ranging across different risk scores. CONCLUSIONS: Our results provide external validation of a simple clinical risk score predicting failed medical treatment in patients with TOA.

RESUMO

This study aimed to investigate the protective effect of ozone therapy on ovarian reserve, number of ovarian follicles, ovarian morphology in a rat ischaemia reperfusion (IR) injury model. Twenty-four, Wistar Hannover rats were included. The rats were divided into three groups as control, detorsion-only, and ozone therapy + detorsion groups. There was a statistically significant difference in the follicular damage and inflammation scores between the study groups (p = .019, p = .002, respectively). The highest AMH decrease was observed in the detorsion-only group (p = .012). The total damage score was higher in the detorsion-only group than the ozone therapy + detorsion group. Preantral, small and large antral follicle numbers were less in the detorsion-only group than the ozone therapy + detorsion group. The highest postoperative day 7 TAS level was in the ozone therapy + detorsion group. TOS levels did not differ significantly between the study groups. The combination of the ozone therapy with ovarian detorsion is more effective in protecting the ovarian reserve than ovarian detorsion-only.Impact StatementWhat is already known on this subject? Adnexal torsion is a common gynecological emergency in reproductive-age women. The recommended management is the detorsion of the adnexal pedicle in patients with fertility desire.What do the results of this study add? The combination of the medical ozone therapy with conventional surgical ovarian detorsion is more effective in the protection of the ovarian reserve compared to surgical ovarian detorsion.What are the implications of these findings for clinical practice and/or further research? This study speculates that medical ozone therapy in addition to conventional surgical ovarian detorsion could preserve ovarian reserve and function if confirmed in further clinical studies.

RESUMO

The essence of the "common therapeutic principle for different diseases"(Yibing Tongzhi in Chinese for short) is the disease-syndrome combination, which is the classic mode of understanding and treating diseases in traditional Chinese medicine(TCM). This study holds the view that Yibing Tongzhi is the optimal treatment mode of ovulation disorders since ovulation disorders have the common pathogenesis, i.e., "kidney-Tiangui(reproduction-stimulating essence)-Chongren(thoroughfare and conception vessels)-uterus axis" disorder. Kidney is an important basis of the reproductive axis, where kidney essence, kidney yang, and kidney Qi are the key substances and driving forces promoting the operation of the reproductive axis. Chongren is an important transmission path. "Tiangui", the upstream substance related to the heart, brain and kidney with a connecting effect, plays a key role in the ovulation mechanism and is a representative of the reproductive axis function. There are four common Tiangui abnormalities in ovulatory disorders, including hypomenorrhea, yin and yang deficiency, abnormal exuberance of extreme yin, and abnormal phase. The dynamic changes of "Tiangui" can induce different diseases, such as polycystic ovary syndrome and hyperprolactinemia, which ultimately lead to anovulatory infertility. Therefore, with "Tiangui" as the entry point, it is the treatment trend for ovulatory disorders under Yibing Tongzhi.

RESUMO

Oocytes are highly radiosensitive, so agents that prevent radiation-induced ovarian follicle destruction are important fertility preservation strategies. A previous study in rhesus macaques demonstrated that ovarian treatment with antiapoptotic agents, sphingosine-1-phosphate (S1P) and FTY720, its long-acting mimetic, preserved follicles following a single dose of 15 Gy X-ray radiation, and live offspring were obtained from FTY720-treated animals. However, it is unknown whether these antiapoptotic agents also protected the ovarian stroma from late effects of radiation, including vascular damage and fibrosis. Using ovarian histological sections from this study, we evaluated the vasculature and extracellular matrix in the following cohorts: vehicle + sham irradiation, vehicle + irradiation (OXI), S1P + irradiation (S1P), and FTY720 + irradiation (FTY720). One ovary from each animal was harvested prior to radiation whereas the contralateral ovary was harvested 10 months post-treatment. We assessed vasculature by immunohistochemistry with a PECAM1 antibody, hyaluronan by a hyaluronan binding protein assay, and collagen by picrosirius red and Masson's trichrome staining. Disorganized vessels were observed in the medulla in the OXI and S1P cohorts relative to the sham, but the vasculature in the FTY720 cohort appeared intact, which may partially explain fertoprotection. There were no differences in the hyaluronan matrix among the cohorts, but there was thickening of the tunica albuginea and fibrosis in the OXI cohort relative to the sham, which was not mitigated by either S1P or FTY720 treatment. Thus, the fertoprotective properties of S1P and FTY720 may be limited given their inability to protect the ovarian stroma against the late effects of radiation-induced fibrosis.

RESUMO

Emerging evidence has demonstrated that melatonin (MT) plays a crucial role in regulating mammalian reproductive functions. It has been reported that MT has a protective effect on polycystic ovary syndrome (PCOS). However, the protective mechanisms of MT remain poorly understood. This study aims to explore the effect of MT on ovarian function in PCOS and to elucidate the relevant molecular mechanisms in vivo and in vitro. We first analysed MT expression levels in the follicular fluid of PCOS patients. A significant reduction in MT expression levels was noted in PCOS patients. Intriguingly, reduced MT levels correlated with serum testosterone and inflammatory cytokine levels in follicular fluid. Moreover, we confirmed the protective function of MT through regulating autophagy in a DHEA-induced PCOS rat model. Autophagy was activated in the ovarian tissue of the PCOS rat model, whereas additional MT inhibited autophagy by increasing PI3K--Akt pathway expression. In addition, serum-free testosterone, inflammatory and apoptosis indexes were reduced after MT supplementation. Furthermore, we also found that MT suppressed autophagy and apoptosis by activating the PI3K-Akt pathway in the DHEA-exposed human granulosa cell line KGN. Our study showed that MT ameliorated ovarian dysfunction by regulating autophagy in DHEA-induced PCOS via the PI3K-Akt pathway, revealing a potential therapeutic drug target for PCOS.

RESUMO

PURPOSE: Estradiol valerate/nomegestrol acetate (E2V/NOMAC) is a new combined oral contraceptive with a good tolerability profile and low drop-out rates, which was shown to improve menstrual-related symptoms. This study aims to evaluate its effectiveness in the control of symptoms and progression of disease in women with ovarian endomestriomas and deep infiltrating endometriosis (DIE). METHODS: This was a retrospective cohort study on 39 women with pelvic endometriosis treated with E2V/NOMAC. We assessed for each patient, at the beginning of treatment and after 6 months, the painful symptoms, through a global VAS (Visual Analogue Scale) index and the size of the greatest ovarian and/or deep infiltrating endometriotic lesions. RESULTS: After 6 months of treatment, a significant reduction was observed for the global VAS score for pain symptoms and for the mean size of ovarian endometriomas, whereas DIE lesions did not present significant changes in mean size. CONCLUSIONS: E2/NOMAC was effective in reducing pain symptoms associated with pelvic endometriosis and the size of ovarian endometriomas, whereas DIE lesions remained stable. This therapy could provide good results in the control of symptoms and disease progression in women with pelvic endometriosis.

RESUMO

OBJECTIVES: Up to 32% of women experience anatomic recurrence after conservative surgery for endometriomas, while pain recurs in 10-40% of cases. Long-term postoperative hormonal therapy is recommended to prevent disease recurrence. We evaluated the efficacy of long-term therapy with estroprogestins (EPs) or progestins (Ps) in preventing endometrioma recurrence, as identifiable cysts and subjective symptoms, after laparoscopic excision. DESIGN: This retrospective cohort study included 375 women submitted to laparoscopic endometrioma excision. Women were followed up at 6 and 12 months and then yearly after surgery. Based on postoperative medical therapy, women were divided into 4 groups: nonusers, cyclic EP users, continuous EP users, and progestogen users. Materials, Setting, Methods: Anamnestic and anthropometric characteristics were collected as well as clinical and surgical data. Gynecological examination, and transvaginal and transabdominal ultrasound scans were performed. Pain (numerical rating score >5) and endometrioma recurrence at ultrasound (ovarian cyst with typical sonographic features ≥10 mm in mean diameter) were recorded at each examination. The reoperation rate in women with recurrence was investigated. RESULTS: The median follow-up was 3.7 years with a maximum of 16.7 years. Most patients used EPs (119 cyclic and 61 continuous users), 95 used P, and 100 were nonusers. In 135 women (36%), endometriotic cyst recurrence was diagnosed, with a mean diameter of 18.7 ± 10.8 mm (range 10-55 mm). The median recurrent cyst-free time was 7.9 years (95% CI 5.8-10.8). Dysmenorrhea was the first symptom to reappear, affecting 162 patients (43.2%). Upon multivariable regression analysis, continuous users had a lower risk of relapse (OR 0.56, 95% CI 0.32-0.99), in terms of both cysts and symptom recurrence, than patients who received no medications. The reoperation rate was 16.2%. LIMITATIONS: The main limitation of this study is its retrospective design. Also, women switching therapies throughout the follow-up period were sorted into one of the study groups based on the longest treatment taken, without considering the discontinuation rates. CONCLUSIONS: Long-term EPs, administered in a continuous regimen and starting immediately after conservative surgery for endometriomas, seem to reduce the disease recurrence risk.

RESUMO

Ruminococcus gnavus is a Gram-positive anaerobe and normal gut commensal in the human host. There have been a small number of reported cases of infections attributed to R. gnavus, and no cases of urogenital infections have previously been published. We describe here a case of bilateral tubo-ovarian abscesses (TOAs) which cultured a pure growth of R. gnavus in a young female with concurrent deep infiltrating endometriosis and evidence of pelvic inflammatory disease. This case provides an insight into the behaviour of R. gnavus as a coloniser of the human host and provides further incentive to investigate its potentially pathogenic role in inflammatory conditions such as pelvic inflammatory disease.

RESUMO

This 5-year retrospective study aimed to investigate whether early surgical management improves outcomes in patients presenting with a tubo-ovarian abscess (TOA). Patient characteristics, investigation results and treatment outcomes were compared. 50 women were diagnosed with a TOA during the study period. Nineteen (38.0%) were treated with antibiotics (medical group) and thirty one (62.0%) were treated surgically on admission (early surgical group). The early surgical group was associated with a high success rate of 96.8% and the lowest risk of readmission within 12 months (16.1%). There was no significant difference in the length of stay between the early surgical and the successful medical group.Impact StatementWhat is already known on this subject? Tubo-ovarian abscess (TOA) is an inflammatory mass that forms most commonly as a complication of untreated pelvic inflammatory disease (PID). Traditionally, TOAs are treated first with broad-spectrum intra-venous antibiotics, with surgical intervention considered after 72 h. It is not known whether early surgical intervention would be beneficial to patient outcomes compared to traditional management.What do the results of this study add? In this study, we have demonstrated a high success rate with early surgical management. Readmission rate was lowest in the early surgical group compared to the medical and late surgical group. This suggests that early surgical intervention may be beneficial, compared to the standard management of trialling antibiotics and then proceeding to surgery 72 h later.What are the implications of these findings for clinical practice and/or further research? Our study suggests that early surgery may be beneficial in the management of TOAs. Although we were unable to demonstrate statistical significance, our data suggest that it would be worthwhile to investigate white blood cell (WBC) and C-reactive protein (CRP) further as a potential predictor for failure of medical management. In the future, more studies comparing early surgical management with medical and late surgical management could inform clinicians of the best mode of treatment for these patients.

RESUMO

The aim of the present study was to evaluate whether hormone therapy containing dienogest is effective in reducing endometrioma size. A retrospective observational study was conducted on 116 women with endometrioma which was evaluated after 6 and 12 months of either no treatment (n = 46), or hormonal therapy containing dienogest (n = 70), without (DNG; n = 34) or with ethinylestradiol (DNG/EE; n = 36). Median (interquartile range) cyst diameter (23.0 mm (21.0 mm)) and volume (9941.2 mm3 (14240.1 mm3)) of untreated were similar to cyst diameter (25.0 mm (14.5 mm) and volume (7587.7 mm3 (13806.2 mm3)) of treated women. After 12 months, endometrioma volume did not vary in untreated women (-34.0 mm3 (55595.0 mm3); -0.77% (93.9%)) while it significantly decreased (-5400 mm3 (15378.7 mm3); -100.0% (27.7%); p<.0001) during hormone therapy. Volume decrease was linearly related to endometrioma volume ([Formula: see text] R2 = 0.899, p<.0001). The effect tended to be greater during DNG alone than DNG/EE (-100.0% (0.0%) vs. -87.9% (47.7%); p<.0004). Cyst disappearance was observed in 4.4% of untreated cases and in 57.1% of cases on hormone therapy (p<.0001) (38.9% with DNG/EE and 76.5% with DNG; p<.03). The early diagnosis and treatment of endometrioma with dienogest-based hormone therapy may be effective in controlling cyst growth and in reducing the need for surgery.

RESUMO

The aim of the present study was to evaluate the effect of medical treatment of ovarian endometriomas on cyst diameter, associated pain, and ovarian reserve as measured with antral follicle count (AFC) and anti-Mullerian hormone (AMH). In this prospective study, 32 patients with unilateral endometrioma associated with pelvic pain, underwent 6-month medical treatment with dienogest. Before treatment, and at the end of 6 months of treatment, patients underwent evaluation of endometrioma diameter and AFC at transvaginal ultrasonography, measurement of AMH, and evaluation of associated pain. Mean cyst diameter was 4.0 ± 1.3 cm at baseline, and 2.4 ± 1.2 cm after 6 months of treatment (p < .0001), for a reduction in diameter of 40% and a reduction in volume of 79%. Mean visual analog scale score at enrollment was 6.3 ± 2.0, with a significant improvement at 6 months (0.9 ± 1.0, p < .0001). AFC for the affected ovary improved from 4.2 ± 2.8 at baseline, to 8.6 ± 4.2 cm after 6 months (+105%; p < .0001). AMH did not change significantly from baseline (3.40 ± 2.32 ng/mL) to end of treatment (2.80 ± 1.90 ng/mL, -18%, p = .27). Medical treatment with dienogest significantly reduces endometrioma diameter and associated pain, whereas the ovarian reserve appears to be preserved, with a significant improvement of AFC and no significant change in AMH.

RESUMO

Ovarian endometriomas are common manifestations of endometriosis. Surgical excision has been shown to potentially decrease ovarian reserves. In this prospective study, we included 81 patients with ovarian endometriosis. 40 were treated with 2 mg of dienogest daily (DNG) and 41 were treated with cyclic oral estro-progestins (ethinyl estradiol 30 mcg [EE] plus dienogest 2 mg) (DNG + EE). Aim of the study was the effect of the treatment on the size of the endometriotic cysts. Further, in the symptomatic patients, follow-up included an evaluation of chronic pain before and during treatment. Both treatments were able to significantly decrease the pain in symptomatic patients with no statistical differences. The mean visual analog scale score at enrollment was 65 ± 14 and 70 ± 18, and there was significant improvement (19 ± 15, p < .001, DNG; 18 ± 12, p < .001, DNG + EE). The size of the endometrioma cysts were significantly reduced in the DNG group. The mean cyst diameter was 52 ± 22 mm at baseline and 32 ± 12 mm after six months of treatment (p < .001), yielding a 75% volume reduction in DNG group. The decrease in the size of endometrioma cysts observed in the women treated with only progestin could be noteworthy, as it may reduce the negative impacts on the affected ovary and avoid surgery.

RESUMO

AIM: Ovarian torsion is a common gynecological emergency of reproductive ages, occurring at rates of 2.7-7.4%. This study aimed to evaluate the antioxidant effects of Nebivolol (NEB) and histopathological changes in experimental ischemic (I) and ischemic-reperfusion (I/R) injury in rat ovaries. METHODS: Forty-eight adult female rats were randomly separated into six groups as group 1 (control) receiving an oral saline solution for 3 days; group 2 (I) that underwent ischemia for 3 h with the application of atraumatic vascular clips; group 3 (I/R); group 4 (I + NEB) receiving 10 mg/kg NEB by oral gavage 30 min prior to the ischemia induction; group 5 (I/R + NEB) receiving 10 mg/kg NEB, and group 6 (control + NEB) receiving oral 10 mg/kg NEB for 3 days before ischemia induction followed by consequent reperfusion. Ovarian tissue damage was scored by histopathological analysis. Ovarian tissue malondialdehyde (MDA) and glutathione (GSH) levels were measured biochemically. RESULTS: The levels of MDA and tumor necrosis factor-alpha (TNF-α), and TUNEL assay positivity scores increased in the I and I/R groups. GSH levels decreased in all case groups (P < 0.05). The oral administration of NEB (10 mg/kg) to the I- and I/R-groups reduced the levels of MDA and TNF-α and TUNEL assay immunopositivity scores (P < 0.05). GSH levels increased in the treatment groups. CONCLUSION: The current experimental ovarian torsion study suggests a protective role for NEB against I and I/R injury in rat ovaries. NEB may be a novel agent for decreasing ovarian I/R injury.
