RESUMO
The aim of present study was to investigate the association between serum calcium, iron, magnesium, copper levels and insulin resistance in women with full blown phenotype of polycystic ovary syndrome (PCOS) compared to women with not-full blown phenotype. 104 women, aged 18-39, in the first phase of menstrual cycle, diagnosed with PCOS based on the Rotterdam Criteria, were qualified for the study. Patients were divided into two groups: group I contained women with full blown PCOS (phenotype A) and group II contained women with not-full blown PCOS (phenotypes B, C and D). Whole study population was divided on group X containing women with proper insulin sensitivity and group Y containing women with insulin resistance. The study found that women with full blown PCOS had lower level of magnesium compared with not-full blown phenotypes. Also, the level of copper was lower in group with proper insulin sensitivity compared to group with insulin resistance. Serum cooper content showed a negative correlation with Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) in group with full blown phenotype. Magnesium level showed positive correlation with level of calcium and cooper in group with proper insulin sensitivity. Level of iron content showed a negative correlation with sex hormone binding globulin (SHBG) and HOMA-IR showed a positive correlation with age and body mass index (BMI) in group with insulin resistance. Either level of calcium showed positive correlation with iron and cooper in group with insulin resistance.
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.

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.

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.
