RESUMEN

ABSTRACT Objective: The aim of this study is to investigate the molecular genetic causes of non-syndromic primary ovarian insufficiency (POI) cases with the gene panel based on next generation sequencing analysis and to establish the relationship between genotype and phenotype. Subjects and methods: Twenty three cases aged 14-40 years followed up with POI were included. Patients with a karyotype of 46, XX, primary or secondary amenorrhea before the age of 40, with elevated FSH (>40 IU/mL) and low AMH levels (<0.03 ng/mL) were included in the study. Molecular genetic analyzes were performed by the next generation sequencing analysis method targeted with the TruSightTM Exome panel. Results: Median age of the cases was 17.8 (14.0-24.3) years, and 12 (52%) cases admitted before the age of 18. Fifteen (65%) patients had consanguineous parents. In 2 (8.6%) cases, variants detected were in genes that have been previously proven to cause POI. One was homozygous variant in FIGLA gene and the other was homozygous variant in PSMC3IP gene. Heterozygous variants were detected in PROK2, WDR11 and CHD7 associated with hypogonadotropic hypogonadism, but these variants are insufficient to contribute to the POI phenotype. Conclusion: Genetic panels based on next generation sequencing analysis technologies can be used to determine the molecular genetic diagnosis of POI, which has a highly heterogeneous genetic basis.

RESUMEN

ObjectiveTo investigate the effects of Xinjia Congrong Tusizi decoction (XJCTD) on ovarian functions in the rat model of premature ovarian insufficiency (POI) and decipher the mechanism of regulating the tumor suppressor protein (p53)/nuclear factor E2-related factor 2 (Nrf2) pathway to attenuate granulosa cell ferroptosis. MethodForty-eight SPF-grade female SD rats were randomized into control, model, low-, medium-, and high-dose (1.1, 2.2, 4.4 g·kg-1) XJCTD, and Western medicine (coenzyme Q10, 0.002 7 g·kg-1) groups, with eight rats in each group. The rat model of POI was established by gavage of triptolide (TP), and after successful modeling, each group was administrated with the corresponding drugs by gavage for 14 d. The body weight and ovarian weight of each rat were weighed and the ovarian index was calculated. The morphology of the ovarian tissue was observed by hematoxylin-eosin staining, and the proportions of growing follicles and atretic follicles were calculated. The serum levels of anti-Müllerian hormone (AMM), estradiol (E2), and follicle-stimulating hormone (FSH) were measured by enzyme-linked immunosorbent assay (ELISA). The DCFH-DA fluorescent probe was used to measure the reactive oxygen species (ROS) content in granulosa cells. The content of cellular Ferrous ion (Fe2+), lipid peroxide (LPO), malondialdehyde (MDA), glutathione (GSH), and superoxide dismutase (SOD) was detected by colorimetry. The expression of the tumor suppressor protein p53,Nrf2, solute carrier family 7 member 11 (SLC7A11), and glutathione peroxidase 4 (GPX4) was determined by immunohistochemistry and Western blot. ResultCompared with the control group, the model group showed decreased ovarian weight, body weight, and ovarian index (P<0.01), reduced ovarian tissue volume and proportion of growing follicles (P<0.01), increased proportion of atretic follicles (P<0.01), lowered AMH and E2 levels and elevated FSH level in the serum (P<0.01), and elevated levels of Fe2+, ROS, LPO, and MDA (P<0.01) and lowered levels of GSH and SOD in granulosa cells (P<0.01). Moreover, the modeling up-regulated the expression of p53 (P<0.01) and down-regulated the expression of Nrf2, SLC7A11, and GPX4 (P<0.05, P<0.01) in the ovarian tissue. Compared with the model group, XJCTD increased the body weight, ovarian weight, and ovarian index (P<0.01), alleviated the pathological changes in the ovarian tissue, increased the proportion of growing follicles (P<0.01), decreased the proportion of atretic follicles (P<0.01), and reduced the content of ROS in granulosa cells (P<0.05, P<0.01). In addition, medium- and high-dose XJCTD lowered the FSH level (P<0.01) and raised E2 and AMH levels (P<0.01) in the serum, reduced the Fe2+ content (P<0.05, P<0.01), and increased the SOD content (P<0.01) in granulosa cells. High-dose XJCTD reduced the LPO and MDA content (P<0.01) and increased the SOD content (P<0.01) in the granulosa cells, down-regulated the expression of p53 (P<0.05), and up-regulated the expression of Nrf2, SLC7A11, and GPX4 in the ovarian tissue (P<0.05, P<0.01). ConclusionXJCTD may protect the ovarian function in the rat model of POI by regulating the p53/Nrf2 signaling pathway to attenuate the ferroptosis of ovarian granulosa cells.

RESUMEN

Abstract Objective Premature ovarian insufficiency (POI) is characterized by early hypoestrogenism. An increased risk of cardiovascular (CV) disease is a long-term consequence of POI. A challenge of hormone therapy (HT) is to reduce the CV risk. Methods Cross-sectional study with lipid profile analysis (total cholesterol, LDL-C, HDL-C, VLDL-C and triglycerides), blood glucose levels and arterial blood pressure of women with POI using HT, compared with age and BMI-matched women with normal ovarian function (controls). Results The mean age and BMI of 102 POI patients using HT and 102 controls were 37.2 ± 6.0 and 37.3 ± 5.9 years, respectively; 27.0 ± 5.2 and 27.1 ± 5.4 kg/m2. There wasn't difference between groups in arterial systolic and diastolic blood pressure, blood glucose levels, total cholesterol, LDL-C, VLDL-C and triglycerides. HDL-C levels were significantly higher in the POI group (56.3 ± 14.6 and 52 ± 13.9mg/dL; p = 0.03). Arterial hypertension was the most prevalent chronic disease (12% in the POI group, 19% in the control group, p = ns), followed by dyslipidemia (6 and 5%, in POI and control women). Conclusion Women with POI using HT have blood pressure levels, lipid and glycemic profile and prevalence of hypertension and dyslipidemia similar to women of the same age and BMI with preserved gonadal function, in addition to better HDL levels.

RESUMEN

Background: Premature ovarian insufficiency (POI) is the preferred term for the condition that was previously referred to as premature menopause or premature ovarian failure. The condition differs from menopause in that there are varying and residual ovarian functions. This study aimed to analyze the clinical characteristics of infertile women with premature ovarian insufficiency. Material & Methods: This prospective study was conducted at the OPD of Impulse Fertility Center, Impulse Hospital, Dhaka, Bangladesh. The study was conducted for a period from January 2022 to December 2022. A total of 23 patients who received outdoor treatment during the study period were purposively selected as sample size. A purposive sampling technique was followed in this study. After approval by the Ethics committee of the Hospital, informed consent from the respondents was obtained after explaining the purpose of the study to them. To be included in the study, respondents should have met the classical definition of infertility defined by the WHO as the inability of a sexually active non-contraceptive using woman to have a live birth after 12 or more months of regular sexual intercourse without a malefactor. Women who had male-factor infertility were excluded. In this study live birth was used as a measure of proven fertility (Because couples desire children, not simply pregnancies, infertility affects couples regardless of whether the etiology lies in conception or the progression of the pregnancy). All the necessary laboratory investigations were done. A questionnaire was developed and data were collected by interviewing the patients and some data were collected from the laboratory results. Data were processed and analyzed by SPSS 19 version. Results: All patients had normal puberty, and menarche occurred at ages 11–15, followed by a regular menstrual cycle. Women who presented with oligomenorrhea were younger than patients with infertility. The mean period of oligomenorrhea before diagnosis was 0.9 years in the oligomenorrhea group and 1.8 years in the infertility group. The mean age when the infrequent periods started was 28 years in the group with oligomenorrhea and 29 years in the group with infertility, and their anthropometric characteristics were not different. In most patients, the FSH levels on day 3 of their menstrual cycle were less than 25?mU/ml. FSH levels >25?mU/ml were confirmed in two patients with oligomenorrhea and five patients in the infertility group. AMH levels were low than 1.0?ng/ml (considered to be in poor ovarian reserve ranges: from 0.13 to 1.0?ng/ml in patients with oligomenorrhea and from 0.13 to 0.9?ng/ml in the infertility group. Transvaginal ultrasound-determined AFC on menstrual cycle days 4–8 was accessed in all patients. We consider AFC?<?6 small follicles (diameters 3–9?mm) as a low ovarian reserve indicator. The lowest AFC (one small follicle) was noted in one infertile patient with oligomenorrhea. Conclusion: This study concluded that the subjects usually present with menstrual irregularity (oligomenorrhea) or infertility, and after proper evaluation, their poor ovarian reserve can be confirmed and an occult form of POI established. women who presented with only oligomenorrhea were younger than infertile patients; therefore, menstrual irregularity may be the earliest clinical symptom of occult POI.

RESUMEN

Objectives: To assess the status of the pelvic floor muscle (PFM) of premature ovarian insufficiency women (POI women) and the incidence of fecal incontinence (FI) and pelvic organ prolapse (POP). Methods: A secondary analysis of a cross-sectional study with 150 women with POI was performed. Pelvic floor muscle assessment was performed with the PERFECT scale. The subscales POPDI-6 and CRADI-8 of the questionnaire Pelvic Floor Distress Inventory-20 (PFDI-20) were used for pelvic floor symptoms focused on FI and POP. Moreover, FI and POP were also assessed as dichotomous variables (yes/no). Results: Women with FI and POP did not present differences in the PFM assessment across P (p = 0.61), E (p = 0.78), R (p = 0.22), and F (p = 0.79) variables when compared with women with POI; no differences were also seen between women with and without POP according the pelvic muscles: P (p = 0.91), E (p = 0.99), R (p = 0.62), and F (p = 0.10). Women with FI and POP presented higher scores in all PFDI-20 subscales and total score when compared with the control group (p < 0.05). Conclusions Pelvic floor muscle assessment within POI women with or without FI or POP did not differ. However, PF symptoms are more severe in the FI or POP groups. (AU)

RESUMEN

ABSTRACT BACKGROUND: Chromosomal abnormalities (CAs) have been described in patients with secondary amenorrhea (SA). However, studies on this association are scarce. OBJECTIVES: To evaluate the frequency and types of CAs detected by karyotyping in patients with SA. DESIGN AND SETTING: This retrospective study was performed in a reference clinical genetic service in South Brazil. METHODS: Data were obtained from the medical records of patients with SA who were evaluated between 1975 and 2022. Fisher's bicaudate exact test and Student's t-test were used, and P < 0.05 was considered significant. RESULTS: Among 43 patients with SA, 14 (32.6%) had CAs, namely del (Xq) (n = 3), 45,X (n = 2), 46,X,r(X)/45,X (n = 2), 46,XX/45,X (n = 1), 46,X,i(q10)/45,X (n = 1), 47,XXX (n = 1), 46,XX/47,XXX (n = 1), 46,XX/47,XX,+mar (n = 1), 45,XX,trob(13;14)(q10;q10)/46,XXX,trob(13;14)(q10;q10) (n = 1), and 46,XX,t(2;21)(q23;q11.2) (n = 1). Additional findings were observed mostly among patients with CA compared with those without CA (P = 0.0021). No difference in the mean age was observed between the patients with SA with or without CAs (P = 0.268025). CONCLUSIONS: CAs are common among patients with SA, especially those with short stature and additional findings. They are predominantly structural, involve the X chromosome in a mosaic, and are compatible with the Turner syndrome. Patients with SA, even if isolated, may have CAs, particularly del (Xq) and triple X.

RESUMEN

The survival rate of cancer patients was improved due to the development of cancer treatment techniques, and thus the fertility protection for young female cancer patients has attracted increasing attention. Radiotherapy, as one of the comprehensive cancer treatment, could cause ovarian damage in adolescent and child-bearing women, which leads to fertility decline and a series of side effects. Radiation can cause ovarian damage not only by acting on biological macromolecules directly, but also by increasing oxidative stress between oocytes and ovarian granulosa cells indirectly. At present, the fertility preservation of female cancer patients undergoing radiotherapy mainly includes physical protection, drug protection and biological protection. Recently, the development of new technologies for the preservation of fertility in female cancer patients has also brought new hope, including factors such as protective effects, patient age, and the selection of specific cancer treatment measures, which are the main considerations in the selection process of fertility preservation measures. This article reviews the research progress on radiation-induced ovarian damage, with a focus on the introduction of the fertility preservation measures and new technologies for young female tumor patients receiving radiotherapy.

RESUMEN

ObjectiveTo investigate the effect and mechanism of Nongsuo Dangguiwan in improving ovarian oxidative stress in rats with ovarian dysfunction. MethodThirty-six adult female SD rats were randomly divided into normal group, model group, positive drug group (Femoston, 0.3 mg·kg-1), and high-, medium-, and low-dose groups of concentrated Nongsuo Dangguiwan (2.08, 4.16, 8.32 g·kg-1), with six rats in each group. Rats, except for those in the normal group, were injected with 80 mg·kg-1 vinyl cyclohexene dioxide (VCD) per day for 14 consecutive days to induce ovarian dysfunction. From the 15th day, rats were treated with corresponding drugs by gavage, while those in the model group received 2 mL·kg-1 saline, once daily for 28 consecutive days. The ovarian index, levels of related hormones including estradiol (E2), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and anti-mullerian hormone (AMH) in serum, as well as superoxide dismutase (SOD) activity and glutathione (GSH) content in serum were measured by enzyme-linked immunosorbent assay (ELISA). The malondialdehyde (MDA) content in serum was detected by the thiobarbituric acid (TAB) method. Ovarian morphology was observed by hematoxylin-eosin (HE) staining. The expression of nuclear factor E2-related factor 2 (Nrf2), heme oxygenase-1 (HO-1), SOD2, and SOD1 in ovarian tissues was detected by immunohistochemistry (IHC) and Western blot. ResultCompared with the normal group, the model group showed a significant reduction in growing follicles in the ovary, loose arrangement of granulosa cells in the follicle, decreased body weight, ovarian index, and serum AMH and E2 levels, increased LH and FSH levels (P<0.01), reduced levels of SOD and GSH in serum (P<0.01), and increased MDA level (P<0.01). Compared with the model group, the groups with drug intervention showed increased ovarian index (P<0.05, P<0.01), increased serum E2 level (P<0.05, P<0.01), decreased FSH, AMH, and LH levels (P<0.05, P<0.01), increased number of growing follicles in the ovary, potentiated SOD activity in serum, increased GSH content, decreased MDA content (P<0.05, P<0.01), and up-regulated expression levels of Nrf2, HO-1, SOD2, and SOD1 proteins in ovarian tissues (P<0.05, P<0.01). ConclusionNongsuo Dangguiwan can regulate serum hormone levels, increase the expression of Nrf2, HO-1, SOD2, and SOD1 in ovarian tissues, and improve ovarian antioxidant capacity to resist oxidative stress injury, thereby improving ovarian reserve function.

RESUMEN

OBJECTIVE@#To explore the effect of "Zhibian" (BL 54)-to-"Shuidao" (ST 28) needle insertion on the ovarian function in the rats with primary ovarian insufficiency (POI) and the potential effect mechanism based on the Fas/FADD/Caspase-8 of death receptor pathway.@*METHODS@#Forty-eight female SD rats were randomly divided into a blank group, a model group, a medication group and an acupuncture group, with 12 rats in each group. Except in the blank group, the rats in the other groups were intraperitoneally injected with cyclophosphamide to establish the POI model. In the acupuncture group, after successful modeling, the intervention was given with "Zhibian" (BL 54)-to- "Shuidao" (ST 28) needle insertion, once daily, 30 min in each intervention; and the duration of intervention was 4 weeks. In the medication group, estradiol valerate tablets were administered intragastrically, 0.09 mg•kg-1•d-1, for 4 weeks. The general situation and the estrous cycle of the rats were compared among groups. Using ELISA, the levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2) in the serum were detected. HE staining was adopted to observe the morphological changes of ovarian tissue of rats. The protein expression of Fas, FADD and Caspase-8 in ovarian tissue was detected with immunohistochemistry and Western blot.@*RESULTS@#After modeling, except the rats of the blank group, the rats of the other groups had dry fur, lost hair, low spirits, reduced food intake, increased urination and loose stool. After intervention, the stool became regular gradually in the acupuncture group and the medication group. The percentage of estrous cycle disturbance was increased in the rats of the model group when compared with the blank group (P<0.01); in comparison with the model group, the percentages of estrous cycle disturbance were reduced in the acupuncture group and the medication group after intervention (P<0.01). When compared with the blank group, the body mass and E2 content in the serum were lower (P<0.01), the levels of FSH and LH in the serum and the protein expression levels of Fas, FADD and Caspase-8 were increased (P<0.01) in the model group. Compared with the model group, the body mass and E2 contents in the serum were higher (P<0.01), the levels of FSH and LH in the serum and the protein expression levels of Fas, FADD and Caspase-8 were reduced (P<0.01) in the acupuncture group and the medication group.@*CONCLUSION@#"Zhibian" (BL 54)-to-"Shuidao" (ST 28) needle insertion can effectively improve the ovarian function of POI rats, and its effect mechanism may be related to regulating the serum sex hormone levels, reducing the expression of Fas, FADD and Caspase-8 in ovarian tissue and retarding apoptosis of ovarian cells.

RESUMEN

OBJECTIVE@#To explore the possible mechanism of acupuncture at "Zhibian" (BL 54) through "Shuidao" (ST 28) on premature ovarian insufficiency (POI) from the perspective of oxidative stress.@*METHODS@#Sixty female SD rats were randomly divided into a blank group, a model group, a sham acupuncture group, a medication group, and an acupuncture group, 12 rats in each group. Except the blank group, the rats in the remaining groups were intraperitoneally injected with cyclophosphamide to establish the POI model. After the model was successfully established, the rats in the acupuncture group were treated with acupuncture at "Zhibian" (BL 54) through "Shuidao" (ST 28), with a depth of about 12 mm, and the needle was retained for 30 min; the acupuncture was given once a day, for a total of 4 weeks. The rats in the sham acupuncture group were treated with blunt-head needle to tap the skin surface of "Zhibian" (BL 54), without penetrating the skin, once a day for 4 weeks. The rats in the medication group were treated with estradiol valerate by gastric gavage for 4 weeks. After the intervention, the level of reactive oxygen species (ROS) in the ovarian tissue was detected by fluorescence probe; the expression of c-Jun N-terminal kinase (JNK), forkhead box O1 (FoxO1), tumor suppressor gene protein 53 (p53) and p53 up-regulated modulator of apoptosis (Puma) mRNA and protein in ovarian tissue were detected by real-time fluorescence quantitative PCR and Western blot.@*RESULTS@#Compared with the blank group, the level of ROS and the expression of JNK mRNA, p-JNK protein, FoxO1, p53, Puma mRNA and protein in the ovarian tissue in the model group were increased (P<0.01). Compared with the model group, the level of ROS and the expression of p-JNK protein, FoxO1, p53, Puma mRNA and protein in the ovarian tissue in the sham acupuncture group were slightly reduced, but the difference was not statistically significant (P>0.05). The level of ROS and the expression of JNK mRNA, p-JNK protein, FoxO1, p53, Puma mRNA and protein in the ovarian tissue in the acupuncture group and the medication group were reduced (P<0.01).@*CONCLUSION@#Acupuncture at "Zhibian" (BL 54) through "Shuidao" (ST 28) could improve the level of oxidative stress, down-regulate the expression of apoptosis-related factors JNK, FoxO1, p53 and Puma induced by oxidative stress, and inhibit the premature failure of ovarian reserve function caused by apoptosis of ovarian granulosa cells in POI rats.

RESUMEN

This study aims to observe the effect and explore the mechanism of Qirong Tablets in the treatment of premature ovarian insufficiency(POI) in mice via the phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt)/hypoxia inducible factor 1(HIF-1) signaling pathway. Sixty SPF female BALB/c mice were randomly divided into normal group, model group, positive control group, Qirong Tablets low-, medium-and high-dose group. The normal group was intraperitoneally injected with the same amount of normal saline, and the other groups were intraperitoneally injected with cyclophosphamide 120 mg·kg~(-1)·d~(-1) once to establish a POI animal model. After the model was successfully established, the low-, medium-and high-dose groups of Qirong Tablets were administered orally with 0.6, 1.2, 2.4 mg·kg~(-1)·d~(-1) respectively. The positive control group was given 0.22 mg·kg~(-1)·d~(-1) Clementine Tablets by intragastric administration, and the normal group and model group were given intragastric administration with the same amount of normal saline, and the treatment was 28 d as a course of treatment. After drug intervention, enzyme-linked immunosorbent assay(ELISA) was employed to measure the levels of estradiol(E_2), follicle-stimulating hormone(FSH), luteinizing hormone(LH), and anti-mullerian hormone(AMH) in peripheral blood, and hematoxylin-eosin(HE) staining to observe the ovarian tissue. Terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling(TUNEL) assay was used to detect the apoptosis of granulosa cells, and Western blot to determine the expression levels of B-cell lymphoma-2(Bcl-2), Bcl-2-associated X protein(Bax), caspase-3, PI3K, Akt, and HIF-1. Compared with the normal group, the modeling of POI caused loose or destroyed ovarian tissue with vacuolar structures, edema and fibrosis in the ovarian interstitium, disordered or loose arrangement of granulosa cells, and reduced normal follicles. Compared with the model group, drug interventions restored the ovarian tissue and follicles at all the development stages and reduced atretic follicles. Compared with the normal group, the modeling of POI lowered the serum level of E_2 and AMH(P<0.01), and elevated the level of FSH and LH(P<0.01). Compared with the model group, high-dose Qirong Tablets elevated the levels of E_2 and AMH(P<0.05), and lowered the levels of FSH and LH(P<0.05). Compared with the normal group, the modeling of POI up-regulated the protein levels of PI3K, Akt, HIF-1, Bax, and caspase-3 and down-regulated the protein level of Bcl-2 in the ovarian tissue(P<0.01). Compared with the model group, low-, medium-, and high-dose Qirong Tablets down-regulated the protein levels of PI3K, Akt, HIF-1, Bax, and caspase-3 proteins and up-regulated the protein level of Bcl-2 in the ovarian tissue(P<0.05). In conclusion, Qirong Tablets can up-regulate the expression Bcl-2, down-regulate the expression of Bax and caspase-3 in POI mice. Qirong Tablets may inhibit the apoptosis of follicular granulosa cells in mice, thereby delaying ovarian aging, improving reproductive axis function, and strengthening ovarian reserve capacity, which may be associated with the inhibition of PI3K/Akt/HIF-1 pathway.

RESUMEN

ObjectiveTo observe the effect of Zhuluan decoction on the ovarian reserve function of rats with cyclophosphamide-induced premature ovarian insufficiency, and explore the protective mechanism of Zhuluan decoction in the rat model of premature ovarian insufficiency based on the phosphatidylinositol-3-kinases/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR) signaling pathway. MethodSixty female SD rats were randomly divided into normal group (n=10) and model group (n=50). The model group was given intraperitoneal injection of cyclophosphamide (50 mg·kg-1 loading dose on the 1st day+8 mg·kg-1 low-dose maintenance on the 2nd–15th days). After successfully modeling, the rats were randomly divided into model group, positive drug (progynova) group (0.1 mg·kg-1·d-1), and low-, medium-, and high-dose Zhuluan decoction groups (14, 28, 56 g·kg-1·d-1 ), with 10 rats in each group. The model group and the normal group were given equal volume of distilled water by gavage, once a day, continuous administration for 21 d. The estrous cycle and body weight of rats in each group were detected, and the ovarian organ index and uterine organ index were calculated. The ovarian tissue pathology and ovarian follicle counts at all levels were determined by hematoxylin-eosin (HE) staining. The content of the serum antimullerian hormone (AMH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and inhibin-B (INH-B) of rats was determined by enzyme-linked immunosorbent assay (ELISA), and the protein expression levels of PI3K, Akt, mTOR in the rat ovarian tissue were determined by Western blot. The microtubule-associated protein 1 light chain 3B (LC3B) protein expression in the rat ovarian tissue was determined by immunohistochemistry. ResultAs compared with the blank group, the estrous cycle of rats in the model group was disordered, the body weight, ovarian organ index, and uterine organ index decreased, the number of primordial follicles decreased, and the number of secondary follicles and atretic follicles increased. In the model group, FSH increased (P<0.01), LH increased (P<0.05), AMH level decreased (P<0.05), the protein expression levels of PI3K, Akt, and mTOR in the ovarian tissue decreased (P<0.01), and the protein expression level of LC3B increased significantly (P<0.01). As compared with the model group, the above indexes were improved in the progynova group and different doses of Zhuluan decoction groups, the content of AMH increased (P<0.05), and FSH decreased (P<0.05). In the progynova group and different doses of Zhuluan decoction groups, the protein expression level of LC3B decreased obviously (P<0.01), and the protein expression levels of PI3K, Akt, and mTOR all showed an increasing trend. Moreover, there was a statistically significant difference in the progynova group and low- and medium-dose Zhuluan decoction groups (P<0.05). ConclusionZhuluan decoction may inhibit the occurrence of excessive autophagy in ovarian granulosa cells by activating the PI3K/Akt/mTOR pathway, thereby reversing the effect of modeling on ovarian reserve in rats.

RESUMEN

ObjectiveTo study the modeling characteristics of the animal model of premature ovarian insufficiency and provide references for the standardization of the animal model of premature ovarian insufficiency, thus offering a better research basis to the pathogenesis, diagnosis, and treatment of the disease. MethodThe animal experimental literature of premature ovarian insufficiency in the past decade was obtained by searching China National Knowledge Infrastructure (CNKI), Wanfang, VIP Chinese Technology Periodical Database, China Biology Medicine (CBM), and PubMed. The types of experimental animals, modeling methods, dosage, administration scheme, modeling standards, and detection indicators were summarized. The frequency analysis was performed with Excel, the association rule analysis was performed with SPSS Modeler 18.0, and the results were visually upgraded with Cytascape 3.6.1. ResultA total of 281 articles were included, and most animal experiments on premature ovarian insufficiency were performed on SD rats or BALB/c mice. Most modeling methods were iatrogenic induction, and the main modeling drug was cyclophosphamide. Erestrous cycle disorder was selected as the modeling standard. Ovarian histomorphology, estradiol, follicle stimulating hormone, and estrous cycle were selected as the detection indicators to comprehensively evaluate the model from multiple aspects. ConclusionSD rats are mostly used to induce modeling in animal experiments on premature ovarian insufficiency through first intraperitoneal injection of cyclophosphamide 50 mg·kg-1 and 8 mg·kg-1·d-1 from the next day for 14 d, which has the advantages of easy operation, high modeling rate, and consistency with the disease pathogenesis. This paper can provide references for basic animal experimental research of premature ovarian insufficiency.

RESUMEN

A 13-year and 6-month-old girl attended the Hunan Children's Hospital due to delayed menarche. The laboratory test results indicated increased follicle-stimulating hormone and luteinizing hormone, decreased anti-Mullerian hormone, and pelvic ultrasound showed a cord-like uterus and absence of bilateral ovaries. Her 11-year and 5-month-old younger sister had the same laboratory and imaging findings, and both girls were diagnosed with primary ovarian insufficiency. Whole exome sequencing and Sanger sequencing confirmed that the proband and her sister carried heterozygous variants of HROB gene c.718C>T (p.Arg240*) and c.1351C>T (p.Arg451*), which were inherited from their parents respectively and consistent with autosomal recessive inheritance. Oral estradiol valerate at an initial dose of 0.125 mg/d was given to the proband, and the secondary sexual characteristics began to develop after 6 months.

RESUMEN

Abstract Objective The present study aimed to develop a useful mathematical model that predicts the age at which premature ovarian insufficiency might occur after teletherapy radiation. A diagnosis of premature or early menopause has physical and psychological consequences, so women may need support and long-term medical follow-up. Methods To correlate ovarian radiation dose with ovarian function, we used the formula described by Wallace et al.: √g(z) = 10(2-0,15z), where "g(z)" and "z" represent oocyte survival rate and the radiation dose (in Gray), respectively. By simulating different ages and doses, we observed a pattern that could be used to simplify the relationship between radiation dose and remaining time of ovarian function. Results We obtained a linear function between ovarian radiation dose and loss of ovarian function (LOF) that is the percentage of decrease in the time to the ovarian failure compared with the time expected for a woman at the same age without irradiation exposition. For patients <40 years old and with ovarian radiation doses < 5 Gy, the equation LOF = 2.70 + (11.08 × Dose) can be applied to estimate the decrease in time to premature ovarian insufficiency. Conclusion The present study reports a practicable theoretical method to estimate the loss of ovarian function. These findings can potentially improve the management and counseling of young women patients submitted to radiotherapy during their reproductive years.


Resumo Objetivo O presente estudo teve como objetivo desenvolver um modelo matemático útil que prediz a idade na qual a insuficiência ovariana prematura pode ocorrer após a radioterapia externa (teleterapia). O diagnóstico de menopausa prematura ou precoce tem consequências físicas e psicológicas; portanto, as mulheres podem precisar de apoio e acompanhamento médico de longo prazo. Métodos Para correlacionar a dose de radiação ovariana com a função ovariana, foi usada a fórmula descrita por Wallace et al.: √g(z) = 10(2-0,15z), na qual "g(z)" e "z" representam a taxa de sobrevivência do oócito e a dose de radiação (em Gray), respectivamente. Ao simular diferentes idades e doses, observamos um padrão que poderia ser usado para simplificar a relação entre a dose de radiação e o tempo restante da função ovariana. Resultados Obtivemos uma função linear entre a dose de radiação ovariana e a perda da função ovariana (LOF, na sigla em inglês) que é a porcentagem de diminuição no tempo até a falência ovariana em relação ao tempo esperado para uma mulher da mesma idade sem exposição à radiação. Para pacientes<40 anos de idade e com doses de radiação ovariana < 5 Gy, a equação LOF = 2,70 + (11,08 × Dose) pode ser aplicada para estimar a redução no tempo até a insuficiência ovariana. Conclusão O presente estudo relata um método teórico viável para estimar a perda da função ovariana. Estes achados podem melhorar potencialmente o manejo e o aconselhamento de pacientes jovens submetidas à radioterapia durante seus anos reprodutivos.

RESUMEN

INTRODUCTION: The frequency of the premutation alleles of the FMR1 gene varies from 1:100 to 1:260 Israeli, Canadian, Finnish and American women, but it is unknown in Brazil. Premutation carriers may have reduced reproductive age and are at risk of transmitting the expanded allele to their offspring, and consequently fragile X syndrome. OBJECTIVE: To observe the distribution range of the FMR1 gene alleles in a population of women with idiopathic infertility, without symptoms of premature ovarian insufficiency. METHODS: The presence of premutation in FMR1 was assessed by conventional PCR, agarose, and acrylamide gel and analysis of fragments in capillary electrophoresis. Lymphocyte DNA obtained from 283 women undergoing infertility treatment was analyzed. RESULTS: 169 patients had the normal heterozygous allele (59.7%), 114 had the normal homozygous allele (40.6%) and no patient had the premutation. Premature ovarian insufficiency is seen in 20 to 30% of women with the permutated allele. Thus, the condition can be asymptomatic in a large part of the premutation carriers. Brazil has a diverse population and, therefore, the allele frequencies of many gene variants are unknown. Previous Brazilian studies have shown a low frequency of the premutation allele in different patient cohorts. Corroborating these articles, the results demonstrated that the frequency of the premutation allele is low in the infertile women population studied. CONCLUSION: Tracking the size of the FMR1 gene alleles allows the expansion of knowledge about the frequency of risk alleles associated with genetic diseases in the Brazilian population.


INTRODUÇÃO: A frequência dos alelos pré-mutados do gene FMR1 varia de 1:100 e 1:260 mulheres israelenses, canadenses, finlandesas e americanas, mas é desconhecida no Brasil. Portadoras da pré-mutação podem apresentar redução da idade reprodutiva e possuem risco de transmissão do alelo expandido para a prole, e consequentemente a Síndrome do X frágil. OBJETIVO: Observar a faixa de distribuição dos alelos do gene FMR1 em uma população de mulheres com infertilidade idiopática, sem sintomas de insuficiência ovariana prematura. MÉTODOS: A presença da pré-mutação em FMR1 foi avaliada por PCR convencional, gel de agarose e acrilamida e análise de fragmentos em eletroforese capilar. Analisou-se DNA de linfócitos obtidos de 283 mulheres em tratamento de infertilidade. RESULTADOS: Foi observado que 169 pacientes apresentam o alelo heterozigoto normal (59,7%), 114 apresentam o alelo homozigoto normal (40,6%) e nenhuma paciente apresentou a pré-mutação. A insuficiência ovariana prematura é observada em 20 a 30% das mulheres portadoras do alelo pré-mutado. Assim, a presença de um alelo pré-mutado pode ser assintomática em grande parte dos casos. O Brasil possui uma população diversificada e, portanto, as frequências alélicas de muitas variantes gênicas são desconhecidas. Estudos brasileiros anteriores mostraram uma baixa frequência do alelo pré-mutado em diferentes coortes de pacientes. Corroborando estes autores, os resultados demonstram que frequência do alelo pré-mutado é baixa na população de mulheres inférteis estudada. CONCLUSÃO: O rastreamento do tamanho dos alelos do gene FMR1 permite ampliar o conhecimento sobre a frequência dos alelos de risco para doenças genética na população brasileira.

RESUMEN

RESUMEN Objetivos: describir un caso de falla ovárica secundaria a una variante patogénica homocigota en el gen STAG3 no reportada previamente. Materiales y métodos: paciente de 16 años con amenorrea primaria y ausencia de características sexuales secundarias, en quien se documentó hipotiroidismo autoinmune, pobre desarrollo genital y cintilla gonadal, por lo cual se realizó secuenciación de exorna clínico. Se identificó una variante homocigota patogénica previamente no reportada en el gen STAG3, el cual ha sido relacionado con insuficiencia ovárica prematura (IOP). Conclusiones: en este caso, la realización de exorna clínico fue determinante para identificar una alteración del gen STAG, probablemente asociada a la IOP y el pronóstico a largo plazo de la paciente. Se establece una nueva variante patogénica c.2773delT; p.Ser925Profs*6 del gen STAG3 asociada a la IOP.


ABSTRACT Objectives: To describe a case of ovarian failure secondary to a homozygous pathogenic variant in the STAG3 gene not previously reported. Material and methods: A 16-year-old patient with primary amenorrhea and absence of secondary sexual characteristics, with documented autoimmune hypothyroidism, poor genital and gonadal streak development which prompted the performance of clinical exorne sequencing. A homozygous pathogenic variant not previously reported in the STAG3 gene, which has been associated with premature ovarian insufficiency (POI), was identified. Conclusions: In this case, clinical exorne sequencing was key for identifying a STAG gene abnormality, probably associated with POI and long term prognosis for the patient. A new pathogenic variant c.2773delT; p.Ser925Profs*6 of the STAG3 gene associated with POI was established.

RESUMEN

El objetivo de este manuscrito es realizar una revisión y actualización de la literatura de la insuficiencia ovárica primaria (IOP) en población adolescente, a partir del diagnóstico, manejo y seguimiento de un caso clínico. La insuficiencia ovárica primaria se define como la menopausia en una mujer antes de los 40 años, acompañada de amenorrea, hipogonadismo hipergonadotrópico e infertilidad. Su prevalencia varía entre 1 a 2%, y en mujeres menores de 20 años su prevalencia es un caso de cada 10,000. Aunque se sabe que muchas afecciones pueden llevar a una IOP, la más común es la causa idiopática. La presentación clínica es diversa, y varios trastornos diferentes pueden también, llevar a esta condición. CASO CLÍNICO: Se presenta el caso de una adolescente de 17 años, previamente sana, con historia de amenorrea secundaria, no embarazada, con examen físico general y ginecológico normal. Se solicita estudio analítico complementario resultando con niveles de hormona folículo estimulante (FHS), estradiol (E2) y hormona antimülleriana (AMH) compatibles con una insuficiencia ovárica como la observada en la posmenopausia. Se inicia terapia hormonal (TH) clásica con estradiol y progesterona, siendo posteriormente reemplazada por anticoncepción hormonal combinada (AHC) oral, coincidente con el inicio de vida sexual, con respuesta favorable y sangrados regulares. La IOP tiene graves consecuencias para la salud incluyendo trastornos psicológicos como angustia, síntomas depresivos o depresión, infertilidad, osteoporosis, trastornos autoinmunes, cardiopatía isquémica, y un mayor riesgo de mortalidad. La enfermedad de Hashimoto es el trastorno autoinmune más frecuente asociado a la IOP. Su tratamiento y diagnóstico deben establecerse de forma precoz para evitar consecuencias a largo plazo. La terapia con estrógenos es la base del tratamiento para eliminar los síntomas de la deficiencia de estrógenos, además de evitar las consecuencias futuras del hipogonadismo no tratado. También el manejo debe incluir los siguientes dominios: fertilidad y anticoncepción, salud ósea, problemas cardiovasculares, función psicosexual, psicológica y neurológica, informando a los familiares y a la paciente sobre la dimensión real de la IOP y la necesidad de tratamiento multidisciplinario en muchos casos. CONCLUSIÓN: El caso presentado, pese a ser infrecuente, permite abordar de manera sistematizada el diagnostico de IOP y evaluar alternativas de manejo plausibles para evitar graves consecuencias en la salud, así como conocer respuesta clínica y de satisfacción de la adolescente.


The objective of this manuscript is to review and update the literature on primary ovarian insufficiency (POI) in an adolescent population, based on the diagnosis, management and follow-up of a clinical case. Primary ovarian insufficiency is defined as menopause in a woman before the age of 40, accompanied by amenorrhea, hypergonadotropic hypogonadism, and infertility. Its prevalence varies between 1 to 2%, and in women under 20 years of age its prevalence is one case in every 10,000. Although it is known that many conditions can lead to POI, the most common is the idiopathic cause. The clinical presentation is diverse, and several different disorders can also lead to this condition. CLINICAL CASE: The case of a 17-year-old adolescent, previously healthy, with a history of secondary amenorrhea, not pregnant, with a normal general physical and gynecological examination is presented. A complementary analytical study is requested, resulting in levels of follicle stimulating hormone (FHS), estradiol (E2) and anti-müllerian hormone (AMH) compatible with ovarian insufficiency such as that observed in postmenopause. Classic hormonal therapy (HT) with estradiol and progesterone was started, later being replaced by combined hormonal contraception (CHC), coinciding with the beginning of sexual life, with a favorable response and regular bleeding. POI has serious health consequences including psychological disorders such as distress, depressive symptoms or depression, infertility, osteoporosis, autoimmune disorders, ischemic heart disease, and an increased risk of mortality. Hashimoto's disease is the most common autoimmune disorder associated with POI. Its treatment and diagnosis must be established early to avoid long-term consequences. Estrogen therapy is the mainstay of treatment to eliminate the symptoms of estrogen deficiency, in addition to avoiding the future consequences of untreated hypogonadism. Management should also include the following domains: fertility and contraception, bone health, cardiovascular problems, psychosexual, psychological and neurological function, informing family members and the patient about the real dimension of POI and the need for multidisciplinary treatment in many cases. CONCLUSION: The case, although infrequent, allows a systematic approach to the diagnosis of POI and evaluate plausible management alternatives to avoid serious health consequences, as well as to know the clinical response and satisfaction of the adolescent.

RESUMEN

O transplante de medula óssea (TMO) é um procedimento indicado para o tratamento de doenças hematológicas, que afetam muitas mulheres jovens. O aperfeiçoamento dos cuidados durante o TMO proporciona altos índices de cura e de sobrevida. No entanto, pode deixar sequelas em vários órgãos e sistemas, entre eles o sistema reprodutor e os órgãos genitais, impactando negativamente a qualidade de vida das receptoras do TMO. O objetivo desta publicação foi realizar uma revisão narrativa sobre o tema e propor um protocolo assistencial que torne acessível os cuidados relacionados à saúde sexual e reprodutiva a esse grupo especial de mulheres, baseado em dados clínicos de um ambulatório de assistência ginecológica às mulheres transplantadas no Hospital Amaral Carvalho, em Jaú, no interior de São Paulo.(AU)


Bone marrow transplantation (BMT) is indicated for the treatment of hematological diseases which affect many young women. The improvement of care during BMT procedures provides higher cure and survival rates. however, it can cause sequelae in various organs and systems, including the reproductive system and genitals, negatively impacting quality of life. The purpose of this publication is to present a narrative review related to this theme and to propose a healthcare protocol that allows sexual and reproductive care in this special group of patients, based on the clinical experience of a gynecological outpatient clinic at the Amaral Carvalho Hospital, in Jaú (SP) which specifically care for these women.(AU)
