RESUMO

Acute genital ulcers can affect females of all ages. In children, they often appear as an emergency and remain a diagnostic challenge for pediatricians, gynecologists and dermatologists. Prompt diagnosis and identification of disease- related factors help to implement appropriate treatment. Firstly, it is crucial to properly compile the past medical history of the patient. Past infectious, autoimmune, malignant or traumatic conditions, as well as vaccinations may contribute to the occurrence of acute genital ulcers. Moreover, new infectious agents, such as severe acute respiratory syndrome coronavirus 2 and vaccinations against Coronavirus disease of 2019, may play a significant role in the development of atypical clinical symptoms. Here we present a case of a 12-year-old girl with acute genital ulcers. Additional symptoms accompanying the ulcer included: abdominal pain, nausea, vomiting, dysuria, vulvar pain and fever. Blood test showed leukocytosis, especially neutrophilia and monocytosis and increased levels of c-reactive protein and procalcitonin. Serological tests for the most common infections were negative. Moreover, the patient had a history of autoimmune diseases. She had periodic fever, aphthous stomatitis, pharyngitis, and adenitis syndrome, and IgA vasculitis, also known as Henoch-Schönlein purpura in her past medical history. Additionally, she was vaccinated against SARS-CoV-2 shortly before the lesions appeared.

RESUMO

BACKGROUND & AIMS: Fatty liver disease (FLD) is common in women with polycystic ovary syndrome (PCOS). Here, we use non-invasive tests to quantify liver injury in women with PCOS and analyse whether FLD-associated genetic variants contribute to liver phenotypes in PCOS. METHODS: Prospectively, we recruited women with PCOS and controls at two university centres in Germany and Poland. Alcohol abuse was regarded as an exclusion criterion. Genotyping of variants associated with FLD was performed using TaqMan assays. Liver stiffness measurements (LSM), controlled attenuation parameters (CAP) and non-invasive HSI, FLI, FIB-4 scores were determined to assess hepatic steatosis and fibrosis. RESULTS: A total of 42 German (age range 18-53 years) and 143 Polish (age range 18-40 years) women with PCOS, as well as 245 German and 289 Polish controls were recruited. In contrast to Polish patients, Germans were older, presented with more severe metabolic profiles and had significantly higher LSM (median 5.9 kPa vs. 3.8 kPa). In the German cohort, carriers of the PNPLA3 p.I148M risk variant had an increased LSM (p = .01). In the Polish cohort, the minor MTARC1 allele was linked with significantly lower serum aminotransferases activities, whereas the HSD17B13 polymorphism was associated with lower concentrations of 17-OH progesterone, total testosterone, and androstenedione (all p < .05). CONCLUSIONS: FLD is common in women with PCOS. Its extent is modulated by both genetic and metabolic risk factors. Genotyping of variants associated with FLD might help to stratify the risk of liver disease progression in women suffering from PCOS.

RESUMO

The coexistence of polycystic ovary syndrome (PCOS) and liver steatosis has been studied for years. The gold standards for the diagnosis of liver steatosis are liver biopsy and magnetic resonance imaging (MRI), which are invasive and expensive methods. The main aim of this study is to check the usefulness of lipid accumulation product (LAP) and free androgen index (FAI) in the diagnosis of liver steatosis. The Ideal IQ MRI was performed in 49 women with PCOS phenotype A to assess the degree of liver steatosis, which was expressed with the proton density fat fraction (PDFF). Anthropometric examination and laboratory tests were performed, and the LAP and FAI were calculated. The correlation between MRI results and LAP, FAI, and one of the FAI components, sex hormone binding globulin (SHBG), was checked using statistical tests. There is a statistically significant correlation between PDFF and LAP and also between PDFF and FAI. LAP = 70.25 and FAI = 5.05 were established as cut-offs to diagnose liver steatosis. The SHBG is not a statistically significant parameter to predict liver steatosis. The study showed that especially LAP, but also FAI, can be used to predict liver steatosis with high specificity and sensitivity.

RESUMO

Pure gonadal dysgenesis is a situation when the karyotype is 46, XY, but for various reasons there is a disorder of differentiation of Wolffian and Mullerian structures and in consequence the phenotype is female. It is known that abdominal gonads and the presence of Y chromosome allow to qualify this condition as a high risk of tumor. In most cases breast development is limited because of lack or low level of estrogen. A 27-year-old patient with differences of sexual development (DSD), was admitted to the Department of Endocrinological Gynecology for a control examination. In the history: dysgerminoma, primary amenorrhea and ambiguous karyotype. The patient has not taken hormonal replacement therapy. The breast development is Tanner stage V.

RESUMO

Insulin resistance is documented in clamp studies in 75% of women with polycystic ovary syndrome (PCOS). Although it is not included in the diagnostic criteria of PCOS, there is a crucial role of this metabolic impairment, which along with hormonal abnormalities, increase each other in a vicious circle of PCOS pathogenesis. Insulin resistance in this group of patients results from defects at the molecular level, including impaired insulin receptor-related signaling pathways enhanced by obesity and its features: Excess visceral fat, chronic inflammation, and reactive oxygen species. While lifestyle intervention has a first-line role in the prevention and management of excess weight in PCOS, the role of anti-obesity pharmacological agents in achieving and maintaining weight loss is being increasingly recognized. Glucagon-like peptide-1 receptor agonists (GLP1-RAs) not only act by reducing body weight but also can affect the mechanisms involved in insulin resistance, like an increasing expression of glucose transporters in insulin-dependent tissues, decreasing inflammation, reducing oxidative stress, and modulating lipid metabolism. They also tend to improve fertility either by increasing LH surge in hypothalamus-pituitary inhibition due to estrogen excess connected with obesity or decreasing too high LH levels accompanying hyperinsulinemia. GLP1-RAs seem promising for effective treatment of obese PCOS patients, acting on one of the primary causes of PCOS at the molecular level.

RESUMO

We investigated the relationship between selected body composition (BC) parameters and included 55 women diagnosed with PCOS and 29 women in which PCOS was excluded. Hormone concentration and BC parameters were assessed during hospitalization. Women with PCOS had higher concentration of luteinizing hormones, total testosterone, androstenedione, and Anti-Müllerian hormones compared to women that were not diagnosed with PCOS. We did not observe any significant differences in the BC parameters between both groups as well as between four PCOS phenotype subgroups. Only in the group of women with PCOS was the concentration of sex hormone binding globulin and free testosterone correlated with all investigated BC parameters. Correspondence analysis did not confirm unambiguously associations between phenotypes of PCOS and the value of BC parameters, while logistic regression revealed that increased Anti-Müllerian hormone concentration and the value of body mass index could be useful parameters in differentiating women with PCOS and women with other disorders. The ROC analysis performed on the entire group of women also confirmed that the concentration of Anti-Müllerian hormones could be a powerful parameter to categorize women as suffering from PCOS.

RESUMO

This study aimed to evaluate the concentration of proprotein convertase subtilisin/kexin type-9 (PCSK9) and the activities of paraoxonase 1 in women with and without polycystic ovary syndrome (PCOS). We found significant higher PCSK9, whereas lower high-density lipoprotein concentration in the serum of women with PCOS when compared to the group without PCOS. Also paraoxonase 1 activities were significantly different between women with PCOS than without PCOS. In addition, the women with PCOS and insulin resistance had higher concentrations of PCSK9 than women with PCOS and insulin sensitivity. Higher PCSK9 concentration in the group with PCOS could be also associated with hormones concentrations. Changes in paraoxonase 1 activities and lipid profile parameters as well as higher concentration of PCSK9 in the group of women with PCOS could be associated with metabolism disorders, but due to the small clinical sample size, the study should be continued.

RESUMO

In a healthy female reproductive system, a subtle hormonal and metabolic dance leads to repetitive cyclic changes in the ovaries and uterus, which make an effective ovulation and potential implantation of an embryo possible. However, that is not so in the case of polycystic ovary syndrome (PCOS), in which case the central mechanism responsible for entraining hormonal and metabolic rhythms during the menstrual cycle is notably disrupted. In this review we provide a detailed description of the possible scenario of PCOS pathogenesis. We begin from the analysis of how a set of genetic disorders related to PCOS leads to particular malfunctions at a molecular level (e.g., increased enzyme activities of cytochrome P450 (CYP) type 17A1 (17α-hydroxylase), 3ß-HSD type II and CYP type 11A1 (side-chain cleavage enzyme) in theca cells, or changes in the expression of aquaporins in granulosa cells) and discuss further cellular- and tissue-level consequences (e.g., anovulation, elevated levels of the advanced glycation end products in ovaries), which in turn lead to the observed subsequent systemic symptoms. Since gene-editing therapy is currently out of reach, herein special emphasis is placed on discussing what kinds of drug targets and which potentially active substances seem promising for an effective medication, acting on the primary causes of PCOS on a molecular level.

RESUMO

OBJECTIVE: The aim of the study was to assess PTX3 levels in PCOS and non-PCOS women in relation to nutritional status and circulating markers of inflammation. METHODS: The study enrolled 99 stable body mass PCOS women (17 normal weight, 21 overweight, and 61 obese) and 61 non-PCOS women (24 normal weight, 19 overweight, and 18 obese). Body composition was assessed by bioimpedance, and plasma levels of pentraxin 3 (PTX3), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and monocyte chemoattractant protein 1 (MCP-1) were measured. Homeostatic model assessment of insulin resistance (HOMA-IR) was made. RESULTS: Plasma PTX3, TNF-α, and IL-6 levels and HOMA-IR were higher in PCOS than in non-PCOS group (p < 0.001). There were positive correlations between log10 (PTX3) and log10 (BMI), waist circumference and fat percentage, as well as log10 (HOMA-IR) and free androgen index but negative between log10 (estradiol) levels in PCOS. While in the non-PCOS group, the correlations between log10 (PTX3) and log10 (BMI), waist circumference and fat percentage, as well as log10 (HOMA-IR) were negative. The positive correlations between PTX3 and MPC-1 and log10 (IL-6) were shown in the PCOS group only. In multivariate regression analyses, variability in PTX3 levels in the PCOS group was proportional to log10 (BMI), waist circumference, and fat percentage, but inversely proportional to log10 (estradiol) levels. While in the non-PCOS group, PTX3 levels were inversely proportional to all anthropometric parameters. CONCLUSIONS: Our results show that the decrease in PTX3 levels observed in obese is distorted in PCOS by microinflammation, and possibly, dysfunction of stroma adipose tissue and liver steatosis is reflected by enhanced insulin resistance.

RESUMO

OBJECTIVES: The aim of the study was to analyze interrelation between plasma omentin-1 levels and nutritional status and inflammation in PCOS. MATERIAL AND METHODS: A cross-sectional study involving 86 PCOS (47 obese) and 72 Non-PCOS women (41 obese) determined anthropometric parameters and body composition. Serum glucose, insulin and omentin-1, TNF-α, sTNFRs, IL-6 and sR-IL6 were measured in the fasting state. RESULTS: Plasma omentin-1 levels were significantly lower in the PCOS than in the Non-PCOS group and both corresponding normal weight and obese subgroups. In three analyzed least-angle regression (LARS) models the lower plasma omentin- 1 levels was associated with PCOS occurrence, higher circulating TNF-α and lower IL-6 levels. CONCLUSIONS: Suppressed omentin-1 levels in PCOS are characteristic for this disturbance and proinflammatory cytokines are factors modifying secretion of this adipokine.

RESUMO

OBJECTIVE: The aim of this study was to evaluate the circulating sclerostin levels with nutritional status, insulin resistance and hormonal disturbances in women with polycystic ovary syndrome (PCOS). PATIENTS AND METHODS: The cross-sectional study involved 98 PCOS inpatients (20 normal weight, 17 overweight and 61 obese) with stable body mass. Body composition was assessed by bioimpedance method in addition to anthropometric measurements (body mass and height). Serum/plasma concentrations of glucose, insulin (with the calculation of homeostatic model assessment insulin resistance-HOMA-IR), estradiol, total testosterone, sex hormone-binding globulin (SHBG) and sclerostin were measured. Free androgen index (FAI) and estradiol/testosterone index were calculated. RESULTS: Plasma sclerostin levels were significantly higher in obese [0.61 (interquartile range 0.53-0.77) ng/mL] than in overweight [0.53 (0.49-0.57) ng/mL] and normal weight [0.49 (0.42-0.54) ng/mL] groups. Plasma sclerostin levels were significantly higher in the subgroup with insulin resistance [0.65 (interquartile range 0.53-0.77) vs. 0.52 (0.46-0.58) ng/mL; p < 0.001], while similar concentrations were observed in subgroups with FAI below and above median. Plasma sclerostin levels variability were explained by BMI (r = 0.40), the percentage of body fat (r = 0.40) and HOMA-IR values (r = 0.34) in multivariable models. CONCLUSIONS: Circulating sclerostin levels in women with PCOS are related to nutritional status and insulin resistance, but not to sex hormone disturbances.

RESUMO

OBJECTIVES: The study aimed to assess the associations between circulating vaspin levels and nutritional status (assessed on tha basis of BMI) as well as insulin resistance in PCOS. MATERIAL AND METHODS: Eighty-seven PCOS women, 48 obese and 39 normal weight, were enrolled in the cross-sectional study. Seventy-two Non-PCOS women, 41 obese and 31 normal weight, constituted a control group. Body mass, height and waist circumference as well as body composition by bioimpedance were measured. In the morning (16h after the last meal) we determined: serum glucose, insulin, androgens, gonadotropin (LH, FSH) and sex hormone-binding globulin (SHBG) as well as plasma vaspin levels. Standard HOMA-IR formula was used to assess insulin resistance (IR). RESULTS: Plasma vaspin levels were significantly lower in PCOS, both normal weight and obese, than in Non-PCOS groups. Vaspin levels were similar in normal weight and obese PCOS subgroups. There was no association between plasma vaspin levels and anthropometric parameters in PCOS group. While in Non-PCOS group a negative correlation between plasma vaspin levels and body mass (r = -0.26; p < 0.05) was found. We did not observe correlations between plasma vaspin levels and serum glucose and insulin concentrations as well as HOMA-IR values, however, in multivariable, stepwise backward regression waist circumference and HOMA-IR values explained 18.0% of plasma vaspin levels variability in the study subjects. CONCLUSIONS: PCOS occurrence is associated with decreased vaspin levels. The influence of nutritional status on vaspin level observed in Non-PCOS is abolished in PCOS women, possibly by more severe insulin resistance.

RESUMO

The aim of this study was to assess concentration of zinc (Zn), copper (Cu), and sirtuin 1 (SIRT1) in serum of women with polycystic ovary syndrome (PCOS) and their relationships with glucose metabolism parameters. The study included 76 women with PCOS aged between 17 and 39 years old. The blood was collected according to the routine procedure during the follicular phase. Zn and Cu concentrations were performed by flame atomic absorption spectrometry (FAAS). Glucose concentration was estimated by colorimetric methods. Insulin (INs) concentration was determined by enzyme-linked immunosorbent assay. SIRT1 concentration was determined using commercial test. We found higher Cu concentration and Cu/Zn value in the serum of women with PCOS with overweight/obesity. Early stage of insulin resistance (IR) in the group of women with PCOS affected on higher Cu concentration and Cu/Zn value. However, increased value of body mass index, waist-hip ratio and homeostatic model assessment of insulin resistance (HOMA-IR) was not associated with changes in Zn and SIRT1 concentration. Further disturbances in glucose metabolic parameters in the blood of women with PCOS were intensified by overweight/obesity and IR. Overweight/obesity and IR in the women with PCOS increase disorders in Cu homeostasis and glucose metabolism parameters.

RESUMO

OBJECTIVE: The aim of the study was to analyze interrelations between estradiol/testosterone (E2/T) and estradiol/androstenedione (E2/A) indexes and nutritional status, insulin resistance in PCOS. STUDY DESIGN: A cross-sectional study involved 76 PCOS (41 obese) and 67 Non-PCOS (40 obese) women. Anthropometric parameters and body composition were assessed. In fasting state of serum glucose, androgens, estradiol, FSH, LH, SHBG and insulin were measured. E2/T and E2/A indexes and the homeostasis model assessment of insulin resistance (HOMA-IR) were calculated. RESULTS: The values of E2/T and E2/A indexes were significantly lower in the PCOS than Non-PCOS subjects, but did not differ significantly between the obese and normal weight groups. The lowest E2/T and E2/A values were observed in the normal weight PCOS group. Multivariable regression analyses revealed that the presence of PCOS was the major factor affecting both the log10 E2/T (ß = -0.16) and log10 E2/A (ß = -0.15) indexes. In addition, log10 E2/A index variability was explained by percentage of body fat (ß = 0.57). HOMA-IR was not among the explanatory factors in all above models. COMMENT: The E2/A index is more affected by nutritional status than E2/T index. The lower value of both indices in PCOS women with normal body mass suggest that aromatase activity in PCOS are related to nutritional status.

RESUMO

One of the consequences of polycystic ovary syndrome (PCOS) is an increased risk of early development of cardiovascular diseases. Pentraxin-3 (PTX-3) is a new potential marker of endothelial dysfunction. The aim of the study was to assess PTX3 and other markers of endothelial dysfunction in PCOS women. The study enrolled 99 stable body mass PCOS women (17 normal weight, 21 overweight and 61 obese). Anthropometric measurements and serum/plasma levels of glucose, insulin, lipids, estradiol, testosterone, sex hormone binding globulin, 17-OH progesterone, free androgen index, pentraxin-3 (PTX3), soluble intercellular (sICAM-1) and vascular cell adhesion molecule 1 (sVCAM-1), endothelin-1 and total nitric oxide metabolites (tNO) concentrations were assessed. Groups were divided into tercile-subgroups according to PTX3 serum levels. Serum PTX3 tercile-subgroups significantly differed in respect to tNO, endothelin-1 and sVCAM-1, but not sICAM-1. The levels of tNO, endothelin-1 and sVCAM-1 were significantly decreased in the subgroup with the lowest PTX3 levels compared to both middle (tNO and endothelin 1) and upper tercile subgroups (all of them). There were significant positive correlations between log10(PTX3) and log10(tNO) (r = 0.34, p < .001), log10(endothelin-1) (r = 0.41, p < .001) as well as sVCAM-1 levels (r = 0.22, p < .05). Circulating PTX-3 levels seem to be a marker of endothelial dysfunction in PCOS women.

RESUMO

The aim of the study was to analyze associations between cognitive deficits and such factors like hormone levels and metabolic risk factors in PCOS women. Fifty-five PCOS patients aged 17-30 underwent analyses for FSH, LH, 17-beta-estradiol, DHEAS, androstenedione, SHBG, lipid profile during the follicular phase. Fasting glucose and insulin concentrations were also measured, as well as their levels after oral-glucose administration. All participants underwent an assessment with: Trail Making Test A and B, Stroop Test, Verbal and Categorical Fluency Test. The intensity of depressive symptoms was measured by the Beck Depression Inventory (BDI). We observed a positive correlation of the depression scores with the OGTT 120' and triglycerides, and a negative correlation of the depression scores with serum HDL. The higher were the insulin levels at 120 min; the more pronounced were the deficits of the verbal psychomotor speed. Higher free testosterone correlated with better verbal psychomotor speed. Androstenedione level was associated with worse scores in executive functions assessment. 17-OH-P levels positively correlated with phonology verbal fluency scores and higher plasma cortisol level at 10 p.m. correlated with worse verbal processing speed. Endocrine and metabolic parameters seem to be important factors mediating cognitive deficits in PCOS.

RESUMO

Our aims were to evaluate N-acetyl-beta-D-glucosaminidase (NAG) activity in an experimental rat model of chronic exposure to cadmium and its response to ozone therapy. Forty male Wistar rats were divided into five groups: control, cadmium only, cadmium and oxygen, cadmium and ozone, and ozone only. Cadmium concentration (ASA method) and NAG activity (by the Maruhn method) were determined in the supernatants of the kidneys, liver, and pancreas. The histopathological alterations were evaluated in tissue sections.The highest concentration of cadmium and NAG activity was observed in rats intoxicated with cadmium. Ozone therapy led to a decrease in cadmium accumulation in the kidneys and liver. An examination of renal, hepatic and pancreatic tissues revealed severe histopathological lesions in Cadmium group (Cd) treated animals. The histopathological changes in animals treated with ozone were similar, but with slightly decreased intensity. Positive correlations between histochemical lesions, NAG activity and cadmium concentration in the study groups were observed. It has been shown that chronic cadmium intoxication has cytotoxic activity in the kidneys, liver, and pancreas, causing an increase in NAG activity. Ozone therapy significantly reduces NAG activity and the severity of histopathological lesions in the kidneys and liver, confirming its beneficial effects.

RESUMO

Aquaporins (AQPs) are transmembrane proteins, able to transport water (and in some cases also small solutes, e. g. glycerol) through the cell membrane. There are twelve types of aquaporins (AQP1-AQP12) expressed in mammalian reproductive systems. According to literature, many diseases of the reproductive organs are correlated with changes of AQPs expression and their malfunction. That is the case in the polycystic ovary syndrome (PCOS), where dysfunctions of AQPs 7-9 and alterations in its levels occur. In this work, we postulate how AQPs are involved in PCOS-related disorders, in order to emphasize their potential therapeutic meaning as a drug target. Our research allows for a surprising inference, that genetic mutation causing malfunction and/or decreased expression of aquaporins, may be incorporated in the popular insulin-dependent hypothesis of PCOS pathogenesis. What is more, changes in AQP's expression may affect the folliculogenesis and follicular atresia in PCOS.

RESUMO

OBJECTIVE: The aim of the study is to analyze daytime changes of prolactin level depending on nutritional status and polycystic ovary syndrome (PCOS). STUDY DESIGN: One hundred and fifteen (69 normal weight, 21 overweight and 25 obese) diagnosed with PCOS and 77 (37 normal weight, 18 overweight and 22 obese) women - Non-PCOS without concomitant diseases were enrolled. Body mass and height were measured and BMI was calculated. Serum concentrations of FSH, LH, E2, testosterone, TSH and PRL were determined morning 6.00 a.m. after wake. Second measurement of PRL was performed at 4 p.m. RESULTS: The daytime decrease of prolactin level was higher in PCOS than in Non-PCOS group regardless of nutritional status (normal weight 35.8 ± 26.0 vs. 24.3 ± 15.3 ng/mL; overweight 28.5 ± 25.4 vs. 17.5 ± 8.8 ng/mL and obese 23.2 ± 21.1 vs. 18.4 ± 11.6 ng/ml, respectively). However, in both PCOS and Non-PCOS daytime changes of prolactin level were higher in normal weight than overweight and obese women (35.8 ± 26.0 vs. 28.5 ± 25.4 vs. 23.2 ± 21.1 ng/mL and 24.3 ± 15.3 vs. 17.5 ± 8.8 vs. 18.4 ± 11.6 ng/mL, respectively). The multivariate regression analysis revealed that the daytime changes of prolactin level are proportional to TSH concentration and coexistence of PCOS as well as inversely relative to BMI. CONCLUSIONS: In conclusions, our results suggest that overweight and obesity decreased morning PRL level and impaired its daytime decrease, but coexistence of PCOS enlarged its.

RESUMO

BACKGROUND/AIMS: In women with chronic kidney disease (CKD) fertility abnormalities occur frequently. Anti-Müllerian hormone (AMH) inhibits excessive recruitment of primordial follicles. The aim of the study was to evaluate the serum AMH concentration in women on hemodialysis and after kidney transplantation (KTx). METHODS: 46 hemodialysed women and 14 with CKD about to undergo kidney transplantation were enrolled into the study. The control group consisted of 40 healthy women. In all subjects serum concentration of AMH was determined (in chronic hemodialysis women and in control group once, and in women after KTx immediately before surgery, and 3 times after the transplantation). RESULTS: Serum AMH concentration in hemodialysed women and in the control group did not differ significantly, while in hemodialysed women with regular menstrual cycles it was significantly lower than in the control group: 2.20 (1.08-3.55ng/ml) and 3.30 (1.80-6.10ng/ml) respectively, (p=0.02). In the KTx group, a significant decrease in serum AMH concentration was found from 3.30ng/ml (2.20-6.50ng/ml) at baseline to 1.90ng/ml (1.30-2.40ng/ml) at 6 months after KTx (p=0.007). CONCLUSIONS: 1. Significantly lower serum AMH concentration was found in the regularly menstruating CKD women on hemodialysis in comparison with the healthy controls. 2. Serum AMH decreased significantly after successful KTx.
