Abstract
Inappropriate sinus tachycardia (IST) is one of the manifestations of the post-COVID-19 syndrome (PCS), which pathogenesis remains largely unknown. This study aimed to identify potential risk factors for IST in individuals with PCS. The 1349 patients with PCS were included into the study. Clinical examination, 24H Holter ECG, 24H ambulatory blood pressure monitoring and biochemical tests were performed 12-16 weeks after the COVID-19 in all participants. IST was found in 69 (3.5%) individuals. In the clinical assessment IST patients were characterized by a higher age (p < 0.001) and lower prevalence of the diagnosed hypertension (p = 0.012), compared to remaining patients. Biochemical testing showed higher serum triglycerides (1.66 vs. 1.31 pmol/L, p = 0.007) and higher prevalence of a low high-density lipoprotein (HDL) cholesterol (24.6% vs. 15.2%, p = 0.035) in the IST group. Subsequently, the triglicerydes (TG)/HDL ratio, an indicator of insulin resistance, was significantly higher in the IST individuals (3.2 vs. 2.4, p = 0.005). 24H monitoring revealed a significantly higher minimum diastolic, maximum systolic and mean arterial blood pressure values in the IST group (p < 0.001 for all), suggesting a high prevalence of undiagnosed hypertension. A multivariate analysis confirmed the predictive value TG/HDL ratio >3 (OR 2.67, p < 0.001) as predictors of IST development. A receiver operating characteristic curve analysis of the relationship between the TG/HDL ratio and the IST risk showed that the predictive cut-off point for this parameter was 2.46 (area under the ROC curve = 0.600, p = 0.004). Based on these findings, one can conclude that insulin resistance seems to be a risk factor of IST, a common component of PCS.

Abstract
The advanced glycosylation end-product receptor (AGER) is involved in the development of metabolic inflammation and related complications in type 2 diabetes mellitus (T2DM). Tissue expression of the AGER gene (AGER) is regulated by epigenetic mediators, including a long non-coding RNA AGER-1 (lncAGER-1). This study aimed to investigate whether human obesity and T2DM are associated with an altered expression of AGER and lncAGER-1 in adipose tissue and, if so, whether these changes affect the local inflammatory milieu. The expression of genes encoding AGER, selected adipokines, and lncAGER-1 was assessed using real-time PCR in visceral (VAT) and subcutaneous (SAT) adipose tissue. VAT and SAT samples were obtained from 62 obese (BMI > 40 kg/m2; N = 24 diabetic) and 20 normal weight (BMI = 20-24.9 kg/m2) women, while a further 15 SAT samples were obtained from patients who were 18 to 24 months post-bariatric surgery. Tissue concentrations of adipokines were measured at the protein level using an ELISA-based method. Obesity was associated with increased AGER mRNA levels in SAT compared to normal weight status (p = 0.04) and surgical weight loss led to their significant decrease compared to pre-surgery levels (p = 0.01). Stratification by diabetic status revealed that AGER mRNA levels in VAT were higher in diabetic compared to non-diabetic women (p = 0.018). Elevated AGER mRNA levels in VAT of obese diabetic patients correlated with lncAGER-1 (p = 0.04, rs = 0.487) and with interleukin 1β (p = 0.008, rs = 0.525) and resistin (p = 0.004, rs = 0.6) mRNA concentrations. In conclusion, obesity in women is associated with increased expression of AGER in SAT, while T2DM is associated with increased AGER mRNA levels and pro-inflammatory adipokines in VAT.

Abstract
Advanced glycation end products (AGEs) are mediators in the process of cellular dysfunction in response to hyperglycemia. Numerous data indicate that the accumulation of AGEs in the extracellular matrix plays a key role in the development of obesity-related adipose tissue dysfunction. Through binding of their membrane receptor (RAGE), AGEs affect numerous intracellular pathways and impair adipocyte differentiation, metabolism, and secretory activity. Therefore, inhibiting the production and accumulation of AGEs, as well as interfering with the metabolic pathways they activate, may be a promising therapeutic strategy for restoring normal adipose tissue function and, thus, combating obesity-related comorbidities. This narrative review summarizes data on the involvement of the RAGE pathway in adipose tissue dysfunction in obesity and the development of its metabolic complications. The paper begins with a brief review of AGE synthesis and the RAGE signaling pathway. The effect of the RAGE pathway on adipose tissue development and activity is then presented. Next, data from animal and human studies on the involvement of the RAGE pathway in obesity, diabetes, and cardiovascular diseases are summarized. Finally, therapeutic perspectives based on interference with the RAGE pathway are discussed.

Abstract
Menopause-related decline in estrogen levels is accompanied by a change in adipose tissue distribution from a gynoid to an android and an increased prevalence of obesity in women. These unfavorable phenomena can be partially restored by hormone replacement therapy, suggesting a significant role for estrogen in the regulation of adipocytes' function. Indeed, preclinical studies proved the involvement of these hormones in adipose tissue development, metabolism, and inflammatory activity. However, the relationship between estrogen and obesity is bidirectional. On the one hand-their deficiency leads to excessive fat accumulation and impairs adipocyte function, on the other-adipose tissue of obese individuals is characterized by altered expression of estrogen receptors and key enzymes involved in their synthesis. This narrative review aims to summarize the role of estrogen in adipose tissue development, physiology, and in obesity-related dysfunction. Firstly, the estrogen classification, synthesis, and modes of action are presented. Next, their role in regulating adipogenesis and adipose tissue activity in health and the course of obesity is described. Finally, the potential therapeutic applications of estrogen and its derivates in obesity treatment are discussed.

Abstract
While low body mass index (BMI) is a risk factor for fractures, the association between obesity and fracture risk is inconsistent and puzzling. Several studies reported higher fracture risk (FR), and others reported lower FR in obese populations. Our narrative review presents the overall incidence of fractures by anatomic locations in adult patients, geriatric populations, and in those after bariatric surgery. In conclusion, obesity should be considered as a fracture risk in adults, as well as falls and fractures in geriatric patients, in particular in those with sarcopenic obesity, and after bariatric surgery. The specific characteristics of fractures risk associated with obesity should be considered by physicians in the diagnostic and therapeutic work-up of obese patients. This review outlines the current literature on this topic and aims to guide physicians regarding proper decisions to prevent fractures in patients with obesity.

Abstract
Skin aging is associated with the accumulation of senescent cells and is related to many pathological changes, including decreased protection against pathogens, increased susceptibility to irritation, delayed wound healing, and increased cancer susceptibility. Senescent cells secrete a specific set of pro-inflammatory mediators, referred to as a senescence-associated secretory phenotype (SASP), which can cause profound changes in tissue structure and function. Thus, drugs that selectively eliminate senescent cells (senolytics) or neutralize SASP (senostatics) represent an attractive therapeutic strategy for age-associated skin deterioration. There is growing evidence that plant-derived compounds (flavonoids) can slow down or even prevent aging-associated deterioration of skin appearance and function by targeting cellular pathways crucial for regulating cellular senescence and SASP. This review summarizes the senostatic and senolytic potential of flavonoids in the context of preventing skin aging.

Abstract
PURPOSE We compared the sexual function in women with classic forms of congenital adrenal hyperplasia (CAH) and polycystic ovary syndrome (PCOS) to find if the cause of androgen excess determines sexual functioning. METHODS Hundred and four women (21 with CAH, 63 with PCOS and 20 healthy controls) aged 18-40 years were included into the study. All participants completed a questionnaire regarding their sociodemographic background and underwent anthropometric and basic biochemical measurements. Plasma levels of total testosterone, androstenedione, and 17-hydroxyprogesterone were measured with immunoassay. To assess the sexual functions, the Female Sexual Function Index (FSFI) questionnaire was applied. RESULTS Apart from the higher physical activity in PCOS patients (P = 0.017), we found no significant sociodemographic differences between the studied groups. In clinical assessment, women with CAH had a lower incidence of acne (P = 0.006). Their plasma levels of 17OHP (P = 0.005) and insulin resistance index (P = 0.0248) were higher, while total testosterone (P = 0.0495) and glucose (P = 0.0061) was lower compared to the PCOS group. Significantly more women with CAH were homosexual (P = 0.003) and bisexual (P = 0.006). CAH group showed a lower total FSFI score (P = 0.0043) and lower scores in three domains: lubrication (P = 0.0131), sexual satisfaction (P = 0.0006), and dyspareunia (P < 0.0001). Higher physical activity was associated in all women with higher total FSFI score (P = 0.009) and scores in the domain of desire (P = 0.034) and sexual satisfaction (P = 0.01), while in CAH women apart from the total score (P = 0.03) and sexual satisfaction (P = 0.002) also in the domains of orgasm (P = 0.005), and pain (P = 0.03). CONCLUSIONS CAH women present more often homosexual and bisexual orientation, while their sexual functions are impaired compared to PCOS patients.

Abstract
The ongoing obesity pandemic generates a constant need to develop new therapeutic strategies to restore the energy balance. Therefore, the concept of activating brown adipose tissue (BAT) in order to increase energy expenditure has been revived. In mammals, two developmentally distinct types of brown adipocytes exist; the classical or constitutive BAT that arises during embryogenesis, and the beige adipose tissue that is recruited postnatally within white adipose tissue (WAT) in the process called browning. Research of recent years has significantly increased our understanding of the mechanisms involved in BAT activation and WAT browning. They also allowed for the identification of critical molecules and critical steps of both processes and, therefore, many new therapeutic targets. Several non-pharmacological approaches, as well as chemical compounds aiming at the induction of WAT browning and BAT activation, have been tested in vitro as well as in animal models of genetically determined and/or diet-induced obesity. The therapeutic potential of some of these strategies has also been tested in humans. In this review, we summarize present concepts regarding potential therapeutic targets in the process of BAT activation and WAT browning and available strategies aiming at them.

Abstract
Sirtuin 6 (SIRT6) exerts a protective effect on health and extends the lives of model organisms. We, therefore, aimed to clarify whether age-related epigenetic drift is responsible for differences in SIRT6 expression in peripheral blood mononuclear cells (PBMCs) of healthy young (n = 55, mean age 27.5 ± 4.4 years), middle-aged (n = 51, 65.4 ± 3.3 years), and long-lived (n = 51, 93.9 ± 3.6 years) humans. In silico analysis was performed using the STRING network. No age-related differences were observed in the percentage of SIRT6 CpG island methylation. However, the age affected the expression of miR-34a-5p, miR-125a-5p, miR-186-5p, miR-342-5p and miR-766-3p (all p < 0.0001), miR-181-2-3p and Let-7c (both p = 0.0003), and miR-103a-3p (p = 0.0069). A negative association was observed between SIRT6 mRNA and miR-186-5p (rs = -0.25, p = 0.026), and a positive association was observed with miR-34a-5p (rs = 0.31, p = 0.0055) and miR-181a-2-3p (rs = 0.39, p = 0.0002). SIRT6 mRNA also negatively correlated with the expression of TP53 (rs = -0.41, p = 0.0126) and MYC (rs = -0.35, p = 0.0448). Notably, the expression of several miRNAs and genes was similar in young and long-lived groups but different from the middle-aged group. We conclude that age-related epigenetic changes can affect the expression of SIRT6 in PBMCs and, in this way, possibly influence immunosenescence. Moreover, molecular events could differentiate 'normal' ageing from that of long-lived individuals.

Abstract
In the assessment of the health risk of an obese individual, both the amount of adipose tissue and its distribution and metabolic activity are essential. In adults, the distribution of adipose tissue differs in a gender-dependent manner and is regulated by sex steroids, especially estrogens. Estrogens affect adipocyte differentiation but are also involved in the regulation of the lipid metabolism, insulin resistance, and inflammatory activity of the adipose tissue. Their deficiency results in unfavorable changes in body composition and increases the risk of metabolic complications, which can be partially reversed by hormone replacement therapy. Therefore, the idea of the supplementation of estrogen-like compounds to counteract obesity and related complications is compelling. Phytoestrogens are natural plant-derived dietary compounds that resemble human estrogens in their chemical structure and biological activity. Supplementation with phytoestrogens may confer a range of beneficial effects. However, results of studies on the influence of phytoestrogens on body composition and prevalence of obesity are inconsistent. In this review, we present data from in vitro, animal, and human studies regarding the role of phytoestrogens in adipose tissue development and function in the context of their potential application in the prevention of visceral obesity and related complications.

Abstract
Purpose/Aim: So far no research concerning the omentin-1 (ITLN1) rs2274907 and vaspin (SERPINA12) rs2236242 polymorphisms has been carried out in a healthy pediatric population. We analyzed associations of these polymorphisms with anthropometric parameters, lipid profile, as well as adiponectin, leptin and soluble leptin receptor (sOB-R) levels in prepubertal healthy children, to search for their possible role in the risk of obesity and obesity-related disorders.Materials and Methods: Frequencies of these polymorphisms were analyzed by the restriction fragment length polymorphism in 89 normal-weight children. The body composition was measured by dual-energy X-ray absorptiometry. Serum levels of adipokines were measured using ELISA methods.Results: We observed differences in values of HDL-cholesterol (p = 0.002) and triglycerides (p = 0.039) in children carrying different genotypes of the ITLN1 rs2274907 polymorphism. In children carrying different genotypes of the SERPINA12 rs2236242 polymorphism differences in BMI (p =0.025) and BMI Z-score (p = 0.01) values were found. Significant relations between anthropometric parameters and levels of HDL-cholesterol and triglycerides were associated with minor alleles of the studied polymorphisms. In addition, leptin/sOB-R ratio was related to HDL-cholesterol (p = 0.004) and triglycerides (p = 0.03) levels in children carrying minor allele of the SERPINA12 rs2236242 SNP.Conclusions: We suggest that both ITLN1 rs2274907 and SERPINA12 rs2236242 polymorphisms influence body composition and lipid profile in prepubertal healthy children. Relations between anthropometric parameters, lipid and adipokine levels may be associated with minor alleles of the studied polymorphisms. The possible role of these polymorphisms in the modulation of the risk of obesity and obesity-related disorders in the later life might be considered.

Abstract
Obesity-related changes in the composition of the body interfere with the proper functioning of the thyrotropic axis, leading to its disturbances and changes in the structure of the thyroid gland. Distinguishing what is related to obesity and what constitutes pathological changes is crucial for the proper treatment of patients. In this paper authors present a case of a patient with a diet-induced obesity, whose only abnormalities in thyroid assessment included an elevated level of thyroid stimulating hormone (TSH) and hypoechoic thyroid gland on ultrasound. Based on this clinical situation, we reviewed literature in order to establish rules regarding management of thyroid disorders in obese individuals. The most common obesity-related thyroid abnormality is an isolated increase of TSH, without clinical symptoms of hypothyroidism, defined as hyperthyrotropinaemia. In obese adults, autoimmune thyroid disease is found equally often as in the normal-weight population. Thyroid enlargement, increased risk of nodules, and decreased echogenicity, not related to autoimmunity, is frequent among obese individuals. Weight loss leads to the normalisation of TSH levels and thyroid echogenicity. Excessive weight can influence both the TSH level and ultrasound image of the thyroid gland; however, these findings can be reversed by weight reduction. Therefore, in asymptomatic obese patients elevated TSH should not be treated with thyroid hormone replacement.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in the developed world. Simple hepatic steatosis is mild, but the coexistence of steatohepatitis (NASH) and fibrosis increases the risk of hepatocellular carcinoma. Proper dietary and pharmacological treatment is essential for preventing NAFLD progression. The first-line treatment should include dietary intervention and increased physical activity. The diet should be based on the food pyramid, with a choice of products with low glycemic index, complex carbohydrates in the form of low-processed cereal products, vegetables, and protein-rich products. Usage of insulin-sensitizing substances, pro- and prebiotics, and vitamins should also be considered. Such a therapeutic process is intended to support both liver disease and obesity-related pathologies, including insulin resistance, diabetes, dyslipidemia, and blood hypertension. In the pharmacological treatment of NAFLD, apart from pioglitazone, there are new classes of antidiabetic drugs that are of value, such as glucagon-like peptide 1 analogs and sodium/glucose cotransporter 2 antagonists, while several other compounds that target different pathogenic pathways are currently being tested in clinical trials. Liver biopsies should only be considered when there is a lack of decline in liver enzymes after 6 months of the abovementioned treatment. Dietary intervention is recommended in all patients with NAFLD, while pharmacological treatment is recommended especially for those with NASH and showing significant fibrosis in a biopsy.

Abstract
OBJECTIVES To investigate the influence of overweight and obesity on general performance and mortality in seniors. DESIGN Cross-sectional multidisciplinary study on ageing of the Polish population. SETTING Community-dwelling individuals aged 65 years or older, selected using three-stage stratified, proportional draw. PARTICIPANTS 4944 Polish Caucasian seniors, aged 65 years or older recruited between October 2007 and October 2010. MEASUREMENTS All study subjects underwent measurement of body mass index (BMI), waist circumference (WC), and arm circumference (AC). The physical and cognitive performance was evaluated using the Katz Activities of Daily Living (ADL) score and Mini-Mental State Examination (MMSE), respectively. Morbidity data were obtained from a medical questionnaire. Mortality data were obtained from the Population Register of Poland between October 2015 and October 2018. RESULTS Increasing age was associated with a decreased prevalence of obesity (all p<0.001). Higher BMI, WC and AC values were associated with higher ADL and MMSE scores (all p<0.001). On multivariate analysis, all three body measurements in women remained independent predictors of the ADL score (BMI p=0.002, WC p=0.005, AC p<0.001) and MMSE score (p<0.001, p=0.003, p<0.001). In men, physical functioning was associated with AC (p=0.003), and cognitive status was associated with AC (p<0.001) and BMI (p=0.013). There was no association between general obesity, abdominal obesity, or AC with several aging-related adverse conditions. Kaplan-Meier survival curves showed that overweight and obesity were associated with the lowest mortality. On multivariate analysis, BMI and AC values remained independent predictors of mortality. In successfully aging individuals, neither BMI, WC, nor AC remained such predictors. CONCLUSIONS Overweight and obesity in Caucasian seniors are not associated with deterioration of physical and cognitive function or with increased mortality.

Abstract
INTRODUCTION Polymorphism of the glucocorticoid receptor gene (NR3C1) may modify protein abundance or function and therefore disturb human homeostasis. METHODS Variant frequencies of the three NR3C1 polymorphisms, rs2963154, rs10515522 and rs2918418, selected in silico as associated with longevity, was analyzed in 552 DNA samples from 95 to 106-year-old individuals and in 284 samples of cord blood DNA from newborns. RESULTS Frequencies of the TT genotypes of rs2963154 and rs10515522, and of the rs291841 CC genotype, were higher in the long-lived study subjects (p = 0.002, p = 0.016 and p = 0.028, respectively). In the long-lived cohort, the rs2963154 CC genotype was associated with higher concentrations of total (p = 0.007) and high-density cholesterol (p = 0.039). The rs10515522 CC genotype was associated with a higher concentration of total cholesterol (p = 0.049). The rs2918418 GG genotype was associated with higher concentrations of total (p = 0.03) and low-density cholesterol (p = 0.03). None of the polymorphisms was associated with fasting glucose, C-reactive protein levels and white blood count, prevalence of diabetes, stroke, myocardial infarction, or cognitive function. However, carriers of the rs10515522 minor allele had significantly better survival rates than carriers of other genotypes. CONCLUSION NR3C1 polymorphisms modify cholesterol levels, and may affect the survival rates of individuals in their tenth and eleventh decades of life.

Abstract
OBJECTIVES The aim of the study was to investigate the role of estrogen receptor type 2 gene (ESR2) variant G1730A in myocardial infarction (MI) in young age. METHODS Genotyping was performed with restriction fragments length polymorphism method in 158 patients (79.1% men) with MI aged <50 years (studied group) and in control groups: 150 healthy individuals aged <50 years (63.3% men) and 202 patients (64.3% men) with MI aged ≥50 years. RESULTS The AA genotype of ESR2 G1730A variant was significantly more frequent in men with MI aged <50 comparing to men with MI aged ≥50 (21.6% vs. 8.4%, P = 0.004) and to healthy young men (21.6% vs. 11.6%, P = 0.048). There was statistically significant difference between AA genotype and GA + GG genotypes male carriers with MI aged <50 in median triglyceride (TG) level (2.0 vs. 1.7 mmol/l respectively, p = 0.023). CONCLUSIONS Our findings suggest a possible role of ESR2 G1730A variant as the risk factor of MI in a young age not as an independent but a potential risk factor associated with TG level in men but not in women.

Abstract
OBJECTIVES Total testosterone/dihydrotestosterone ratio (TT/DHT) was found to determine metabolic risk in polycystic ovary syndrome (PCOS). The aim of this study was to analyze whether (TT/DHT) may be helpful in predicting metabolic risk not only in PCOS patients but also in healthy women. MATERIAL AND METHODS Total testosterone (TT), dihydrotestosterone (DHT), androstendione and dehydroepiandrosterone sulphate (DHEA-S) were measured by LC-MS/MS in 36 women with PCOS and in 29 age-matched controls without clinical hyperandrogenism. In all participants, anthropometric data, lipids, adipose tissue percent (%fat), HOMA-IR were also assessed. RESULTS The studied groups were not different in terms of age, BMI, waist circumference, %fat and HOMA-IR. In the patients group, mean TT and androstendione levels were significantly higher as compared to controls (1.4 nmol/L vs. 1.0 nmol/L, P < 0.001) and (6.6 nmol/L vs. 4.9 nmol/L, P < 0.01), respectively. In the patients group, mean TT/DHT ratio was significantly higher compared to controls (3.6 vs. 2.7, P < 0.01) and correlated with BMI (r = 0.37, P < 0.05), waist circumference (r = 0.44, P < 0.01), %fat (r = 0.30, P < 0.05), as well as with insulin levels (r = 0.38, P < 0.05) and HOMA-IR (r = 0.44, P < 0.05). The association between TT/DHT ratio and unfavorable metabolic parameters was also seen in controls. CONCLUSION Total testosterone/dihydrotestosterone ratio assessed by LC-MS/MS correlates with a worse metabolic profile not only in PCOS patients, but also in healthy women.

Abstract
In obese individuals, weight loss might be affected by variants of the adipokine-encoding genes. We verified whether selected functional single nucleotide polymorphisms in LEP, LEPR and ADIPOQ are associated with changes in serum levels of the respective adipokines and weight loss in 100 prepubertal obese (SDS-BMI > 2) Caucasian children undergoing lifestyle intervention. Frequencies of the -2548G > A LEP, Q223R LEPR, K656N LEPR, -11377C > G and -11426A > G ADIPOQ polymorphisms were analyzed by restriction fragment length polymorphism. Serum adipokine and soluble leptin receptor (sOB-R) concentrations were measured using the ELISA method. Among the analyzed polymorphisms, only LEPR polymorphisms were associated with changes of SDS-BMI or sOB-R concentrations in children after therapy. Carriers of the wild-type K665N and at least one minor Q223R allele had the greatest likelihood of losing weight (OR = 5.09, p = 0.006), an increase in sOB-R (ptrend = 0.022) and decrease in SDS-BMI correlated with the decrease of fat mass (p < 0.001). In contrast, carrying of the wild-type Q223R and at least one minor K665N allele were associated with a decrease in sOB-R concentrations and a decrease in SDS-BMI correlated with a decrease in fat-free mass (p = 0.002). We suggest that the combination of different LEPR variants, not a single variant, might determine predisposition to weight loss in the prepubertal period.

Abstract
OBJECTIVE As nonclassic congenital adrenal hyperplasia (NCCAH) needs to be taken into account in women with hyperandrogenism, we aimed to assess whether the recommended level of poststimulated 17OHP ≥30 nmol/l confirms NCCAH. PATIENTS AND METHODS Forty, consecutive women with biochemical and/or clinical hyperandrogenism (aged 25·4, 18-38) suspected of having NCCAH were recruited to the study. In patients with 17OHP level between 5·1 and 29·9 nmol/l an ACTH stimulation test was performed. In patients with basal or poststimulated 17OHP ≥30 nmol/l, twenty-four-hour urinary steroid profile (USP) analysis was performed and CYP21A2 mutation was assessed. In selected patients with poststimulated 17OHP <30 nmol/l USP was also performed. RESULTS The group was divided into two subgroups with basal or poststimulated 17OHP ≥30 nmol/l (group A) and with poststimulated 17OHP <30 nmol/l (group B). Among 40 patients, basal or poststimulated 17OHP ≥30 nmol/l was found in 21, but NCCAH was confirmed by USP followed by genetic testing only in 5 (24%). Four patients were diagnosed as heterozygotes, and in twelve, no CYP21A2 mutation was detected. CONCLUSION The diagnosis of NCCAH based only on serum 17OHP measurements (basal or poststimulated) may lead to false-positive diagnosis when performed by immunoassay with a cut-off value of ≥30 nmol/l. The definitive diagnosis can be established based on USP and/or genetic testing.

Abstract
Basal serum 17OHP measurement remains the first screening step for nonclassic congenital adrenal hyperplasia (NCCAH) and the accuracy of the test is of high value. The aim of this study was to compare the accuracy of immunoassays to LC-MS/MS in the assessment of serum 17OHP and androgens concentration in women with hyperandrogenism and controls. 17OHP, total testosterone, androstendione and DHEA-S were measured in 39 women with clinically and/or biochemically evident hyperandrogenism and in 29 age-matched controls without clinical hyperandrogenism. 17OHP and androgens were measured by immunoassays and by LC-MS/MS. In patients group median 17OHP level measured by immunoassays was significantly higher compared to LC-MS/MS (5.49 nmol/l-ELISA NovaTec® and 3.57 nmol/l-ELISA DRG® versus 1.56 nmol/l-LC-MS/MS p < 0.0001) as well as in the control group (2.58 nmol/l-ELISA DRG® versus 1.14 nmol/l-LC-MS/MS p < 0.0001). Additional, unnecessary diagnostic procedures explaining elevated 17OHP level were undertaken in 85% of patients when NovaTec® test was used, in 50% when ELISA DRG® and in none when LC-MS/MS method was applied. Total testosterone, androstendione and DHEA-S concentrations in the patients and the controls assessed by the immunoassays were also significantly higher compared to LC-MS/MS. LC-MS/MS is more reliable diagnostic tool in the measurement of serum 17OHP and androgens concentrations compared to immunoassays in women with hyperandrogenism.

Abstract
Interleukin-6 (IL-6) may play an important role in the pathogenesis of Graves' ophthalmopathy (GO). The aim of this study was to analyze the association of IL-6 gene promoter polymorphism, at position - 174 (G --> C, termed as G-174C), which may affect IL-6 production, with the development of GO. The G-174C polymorphism was determined in 279 Polish-Caucasian patients with Graves' disease (GD), of which 108 had clinically evident ophthalmopathy (NOSPECS class III or higher) and 186 healthy Polish adults. In patients with GD, the frequencies of the C allele (45 vs 42%; P = 0.35) and C/C genotype (20 vs 15%; P = 0.13) were not significantly different compared to controls. Subdividing patients with GD for the presence of eye disease revealed that the C allele (44 vs 45%; P = 0.76) and C/C genotype (20 vs 20%; P = 0.92) were equally distributed in patients with or without ophthalmopathy. There was also no association between the G-174C polymorphism and the severity of eye changes. Finally, IL-6 genotypes were not associated with laboratory findings (thyroid volume, serum IL-6 and thyroid autoantibodies levels) in patients with GD at diagnosis. Our results suggest that G-174C polymorphism of the IL-6 gene does not contribute to the development and severity of GO.

Abstract
Although autoimmune diseases are relatively common, mechanisms that lead to their development remain largely unknown. Nuclear factor-kappaB (NF-kappaB), as a key transcription factor involved in the regulation of immune responses and apoptosis, appears to be a good candidate for studies on the pathogenesis of autoimmunity. This review presents how perturbations of the NF-kappaB signaling pathway may contribute to self-tolerance failure, initiation of autoimmune inflammatory response as well as its persistent maintenance and therefore to the development of common autoimmune diseases including rheumatoid arthritis, multiple sclerosis, type 1 diabetes mellitus, thyroid autoimmune diseases, systemic lupus erythematosus as well as inflammatory bowel diseases and psoriasis. A special emphasis is put on the genetic variations in the NF-kappaB related genes and their possible association with susceptibility to autoimmune diseases, as well as on the therapeutic potential of the NF-kappaB targeted strategies in the treatment of autoimmunity.

Abstract
There is a growing number of diseases which prevalence can be associated with vitamin D deficiency. The link between low cholecalciferol concentration and bone diseases is well established, however there is also data suggesting that it may influence development and progression of different cancers and autoimmune diseases. The in vitro studies proved that the active vitamin D metabolite--1,25(OH)(2)D(3) may arrest the cell cycle progression, induce apoptosis as well as regulate T cells and antigen presenting cells function. Results of the in vivo experiments suggest that vitamin D deficiency accelerates development of autoimmune diseases and cancers in animals. Epidemiological studies imply that the vitamin D deficiency is also associated with the increased incidence of autoimmune diseases and cancers in people. The main determinant of vitamin D serum concentration in a human body is skin synthesis. The changes in the lifestyle, air pollution as well as a common use of sun screens caused that the contemporary European receives little sunlight compared to his ancestors. According to the recent epidemiological studies, the vitamin D concentrations in serum of people who live in high latitudes (above 34 degrees N/S), including Poland, is far from being sufficient. This paper reviews results of the recent studies concerning the potential role of the vitamin D in the development of cancers and autoimmune diseases, as well as provides guidelines for vitamin D supplementation.

Abstract
Tumor necrosis factor (TNF)-alpha plays a central role in the development of ophthalmopathy in patients with Graves' disease (GD). The aim of this study was to investigate the association of TNF promoter polymorphisms at positions -1031 (T-1031C), -863 (C-863A), -857 (C-857T), -308 (G-308A), and -238 (G-238A) with Graves' ophthalmopathy (GO). We studied the distribution of TNF and human leukocyte antigen (HLA) DRB1 alleles in 228 Polish white patients with GD, 106 of whom had ophthalmopathy (NOSPECS class > or = III) and 248 healthy subjects. TNF -308A and HLA-DRB1*03 alleles were significantly increased in patients with GD compared with healthy subjects. Stratification analysis revealed no independent association of -308A with GD when the DRB1*03 status was considered. Subdividing GD according to eye involvement revealed that the distribution of TNF promoter haplotypes differed significantly in patients with or without ophthalmopathy. The haplotype containing the -238A allele was absent in GO. The association of G-238A with GO was independent of DRB1 alleles. These results indicate that TNF G-308A is associated with susceptibility to GD (however, this association is not independent of HLA-DRB1*03) and that TNF G-238A is associated with the development of ophthalmopathy, suggesting that G-238A or a gene in linkage disequilibrium may be disease modifying in GD.
