The article highlights the current data on the prevalence and pathogenesis of osteoarthritis (OA), presents a new definition of the disease, research results on the heterogeneity of OA, its relationship with obesity and metabolic syndrome. Obesity is one of the main factors in the development and more rapid progression of OA, and the presence of metabolic syndrome not only increases the risk of developing the disease, but also determines its severity. It is noted that with an increase of the components of the metabolic syndrome, the severity of OA increases. Therefore, hyperuricemia is associated with the presence of osteophytes and the progression of osteoarthritis, hyperglycemia - with the severity of the clinical manifestations and radiological progression. Much attention is given to the treatment of patients with OA and The European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (ESCEO) recommendations for the treatment of knee joints OA updated in 2019. In which for the first time a symptomatic slow-acting drugs for osteoarthritis (SYSADOAs) are assigned as the basis in the treatment of OA. The data on the effectiveness of some drugs from this group are presented. The glycosaminoglycan-peptide complex, which contains pharmacologically high-quality chondroitin sulfate when administered intramuscularly, has a significant effect on the symptoms, and in case of continued use, slows the progression of OA. The multicenter open-label prospective study of diacerein in patients with knee-joint OA combined with metabolic syndrome showed that during therapy pain syndrome and stiffness are reduced, and functional condition of the joints and quality of life of patients improves quickly and significantly. In addition, the positive effect of the drug on some components of the metabolic syndrome was demonstrated: a significant decrease in body mass index, low density lipoproteins, triglycerides, glucose and uric acid.

ObjectiveHigh as well as low levels of IGF1 have been associated with cardiovascular diseases (CVD). The relationship of IGF1 with (components of) the metabolic syndrome could help to clarify this controversy. The aims of this study were: i) to investigate the association of IGF1 concentration with prevalent (components of) the metabolic syndrome; and ii) to examine the role of (components of) the metabolic syndrome in the relationship between IGF1 and incident CVD during 11 years of follow-up.MethodsData were used from the Longitudinal Aging Study Amsterdam, a cohort study in a representative sample of the Dutch older population (≥65 years). Data were available in 1258 subjects. Metabolic syndrome was determined using the definition of the US National Cholesterol Education Program Adult Treatment Panel III. CVD were ascertained by self-reports and mortality data.ResultsLevels of IGF1 in the fourth quintile were associated with prevalent metabolic syndrome compared with the lowest quintile (odds ratio: 1.59, 95% confidence interval (CI) 1.09–2.33). The middle up to the highest quintile of IGF1 was positively associated with high triglycerides in women. Metabolic syndrome was not a mediator in the U-shaped relationship of IGF1 with CVD. Both subjects without the metabolic syndrome and low IGF1 levels (hazard ratio (HR) 1.75, 95% CI 1.12–2.71) and subjects with the metabolic syndrome and high IGF1 levels (HR 2.28, 95% CI 1.21–4.28) demonstrated increased risks of CVD.ConclusionsIn older people, high-normal IGF1 levels are associated with prevalent metabolic syndrome and high triglycerides. Furthermore, this study suggests the presence of different pathomechanisms for both low and high IGF1 levels and incident CVD.

Introduction. Fasting glucose (FG) is part of the Adult Treatment Panel III (ATP III) criteria for defining the metabolic syndrome (MetS). Glycated hemoglobin (HbA1c) is a measure of 2-3 month endogenous glucose exposure and is now recommended for diabetes diagnosis and screening for high-risk individuals. The aim of this study was to evaluate if replacing FG with HbA1c to define MetS improves prediction of incident coronary heart disease (CHD) in the Atherosclerosis Risk in Communities (ARIC) cohort. Methods. We included 11,194 ARIC participants without diabetes (based on diagnosis, medication use, FG ≥126 mg/dL, or HbA1c ≥6.5%) or prevalent CHD at baseline (1990-92). Cox proportional hazards models (adjusted for age, race, and study center) were used to compare the association between MetS defined using HbA1c (5.7-6.4%) or FG (100-125 mg/dL, based on ATP III guidelines) and risk of CHD (defined by myocardial infarction or fatal CHD, event data available through 2009). Results. Study participants had a mean age at baseline of 57 years, 43% were male, and 79% were white; median follow-up time was 16 years. Thirty-four percent of the study population had both normal FG (<100 mg/dL) and HbA1c (<5.7%), 37% had elevated FG and normal HbA1c, 4% had normal FG and elevated HbA1c, and 25% had both elevated FG (100-125 mg/dL) and HbA1c (5.7-6.4%). The association of combined FG and HbA1c categories with incident CHD are shown in the Figure. The adjusted hazard ratio predicting for incident CHD from MetS status was 1.43 (95% CI: 1.25-1.63, c-statistic: 0.61) using FG in the definition of MetS and 1.69 (95% CI: 1.48-1.93, c-statistic: 0.62) in the model replacing FG with HbA1c. Conclusions. Incorporating HbA1c into the definition of the MetS may help in identifying individuals who should be targeted for aggressive CHD risk factor reduction. Additionally, HbA1c may be useful clinically and in research settings for identifying individuals with MetS in cases where FG measures are not available.

Abstract Metabolic syndrome is a term linking the clinical profiles of some of the world's major health problems today: obesity, heart disease, and diabetes. It is predicated on dietary patterns, and particularly on the delivery of fuel. The effects may be seen first in the development of abdominal obesity and insulin resistance leading to Type 2 diabetes mellitus and coronary heart disease. This review examines the role resistant starch might play in the prevention and management of these conditions. Beginning with a definition of resistant starch, a critical review of the scientific literature is presented. Current knowledge suggests that resistant starch in the diet may assist in the prevention and management of conditions associated with the metabolic syndrome via its potential effects on delaying the delivery of glucose as fuel with subsequent fat utilization and appetite control benefits. There is still a great deal of research to be undertaken in this area, but it is clearly warranted, given the position of starches in the global food supply and the potential impact on population health.

Conclusion: The definition of metabolic syndrome needs further refinement and it requires long-term outcome studies to evaluate the various criteria definitively. In general, however, differences of opinion surrounding the syndrome are minor.

Recent reports suggest that IGF (insulin-like growth factor)-I and IGFBP-3 (IGF-binding protein-3) have independent and opposing mechanistic effects on insulin. The aim of the present study was to assess the relationship between the IGF-I/IGFBP-3 ratio and the metabolic syndrome. We examined 3281 subjects (1463 men and 1818 women, aged 20–49 years), otherwise healthy adults, who participated in NHANES III (Third National Health and Nutrition Examination Survey), which has released measurements of IGF-I and IGFBP-3. Insulin resistance was estimated using the computer HOMA2 (homoeostatic model assessment 2) model. The updated ATP-III (Adult Treatment Panel III) definition of the metabolic syndrome was used. We applied adjusted logistic and linear regression models. After adjusting for age and race, men and women in the lowest quartile of the IGF-I/IGFBP-3 ratio were 3-fold more likely to meet the ATP-III definition of the metabolic syndrome and twice as likely to be insulin-resistant. Mean values of the IGF-I/IGFBP-3 ratio decreased significantly as the number of metabolic syndrome components increased (P<0.0001, as determined by ANOVA). The area under the ROC (receiver operating characteristic) curve for detecting insulin resistance using the IGF-I/IGFBP-3 ratio was 0.760, significantly improving upon either protein alone (P=0.01). In conclusion, the IGF-I/IGFBP-3 ratio is significantly associated with the metabolic syndrome. Calculating the ratio of these two proteins may provide insight into the metabolic syndrome clustering phenomenon.

Background. Metabolic and genetic factors induce plasminogen activator inhibitor type-1 (PAI-1) overexpression; higher PAI-1 levels decrease fibrinolysis and promote atherothrombosis.Aim. To assess PAI-1 antigen levels among subjects with type 2 diabetes mellitus (T2DM) plus Metabolic Syndrome (MetS) before clinical manifestations of atherothrombosis and the contribution of metabolic factors and 4G/5G polymorphism of PAI-1 gene on the variability of PAI-1.Methods. We conducted an observational, cross-sectional assay in a hospital in Mexico City from May 2010 to September 2011. MetS was defined by the International Diabetes Federation criteria. PAI-1 levels and 4G/5G polymorphism were determined by ELISA and PCR-RFLP analysis.Results. We enrolled 215 subjects with T2DM plus MetS and 307 controls. Subjects with T2DM plus MetS had higher PAI-1 levels than the reference group (58.4 ± 21 versus 49.9 ± 16 ng/mL,p=0.026). A model with components of MetS explained only 12% of variability on PAI-1 levels (R2= 0.12;p=0.001), withβ=0.18(p=0.03) for hypertension,β=-0.16(p=0.05) for NL HDL-c, andβ=0.15(p=0.05) for NL triglycerides.Conclusion. Subjects with T2DM plus MetS have elevated PAI-1 levels before clinical manifestations of atherothrombotic disease. Metabolic factors have a more important contribution than 4G/5G polymorphism on PAI-1 plasma variability.

Objective Craniopharyngioma patients often have poor metabolic profiles due to hypothalamic–pituitary damage. Previously, using BMI as obesity marker, the occurrence of the metabolic syndrome in these patients was estimated at 46%. Our aim was to determine if dual X-ray absorptiometry (DXA) scan in evaluation of obesity and metabolic syndrome would be superior. Design Retrospective study of craniopharyngioma patients for whom DXA scan results were available. Methods BMI, fat percentage and fat mass index were used to evaluate obesity and as components for obesity in metabolic syndrome. Results Ninety-five craniopharyngioma patients were included (51% female, 49% childhood-onset disease). Metabolic syndrome occurred in 34–53 (45–51%) subjects (depending on the definition of obesity, although all definitions occurred in higher frequency than in the general population). Metabolic syndrome frequency was higher if obesity was defined by fat percentage (52 vs 42%) or fat mass index (51 vs 43%) compared to BMI. Misclassification appeared in 9% (fat percentage vs BMI) and 7% (fat mass index vs BMI) for metabolic syndrome and 29 and 13% for obesity itself, respectively. For metabolic syndrome, almost perfect agreement was found for BMI compared with fat percentage or fat mass index. For obesity, agreement was fair to moderate (BMI vs fat percentage). Conclusion Using BMI to evaluate obesity underestimates the true prevalence of metabolic syndrome in patients with craniopharyngioma. Furthermore, fat percentage contributes to a better evaluation of obesity than BMI. The contribution of DXA scan might be limited for identification of the metabolic syndrome.

Abstract Background and Aims: Comparative estimation of metabolic syndrome (MS) mediated changes of blood, cardio-vascular system, liver, pancreas and kidneys morphologic structure in adult and pubertal rats. Materials and Methods: Wistar albino male rats of two age categories (young animals of 21 days age (50-70g) and adults (160-180g)) were divided into 4 groups (8 animals in each): 1 - Control 1 (intact young rats); 2 - Control 2 (intact adult rats); 3 - MS3 (young rats with MS) and 4 - MS4 (adult rats with MS). The metabolic syndrome model was induced by full replacement of drinking water with 20% fructose solution (200g/l). After 60 days of MS modeling, determination of rat hematological and serum biochemical parameters, glucose tolerance, blood pressure, liver rates of lipid peroxydation and chromatin DNA fragmentation, as well as morphological macroscopic and microscopic studies were carried out. Results: In pubertal rats, glucose tolerance, hypertension, blood clotting disturbances, DNAfragmentation and lipid peroxydation rates were affected more profoundly, while mature rats showed greater Pseudo Pelger-Huet anomaly development, serum cholesterol and lipoproteins increases, liver and kidney morphology changes. Conclusions: Our current data combined with previous results of other authors allow us to conclude that an animal model (Wistar rats) of MS is quite easily obtained in a full age range, from juvenile to mature rats.
