There has been an increasing prevalence of kidney stones over the last 2 decades worldwide. Many studies have indicated a possible association between metabolic syndrome and kidney stone disease, particularly in overweight and obese patients. Many different definitions of metabolic syndrome have been suggested by various organizations, although the definition by the International Diabetes Federation (IDF) is universally considered as the most acceptable definition. The IDF definition revolves around 4 core components: obesity, dyslipidemia, hypertension, and diabetes mellitus. Several hypotheses have been proposed to explain the pathophysiology of urolithiasis resulting from metabolic syndrome, amongst which are the insulin resistance and Randall’s plaque hypothesis. Similarly the pathophysiology of calcium and uric acid stone formation has been investigated to determine a connection between the two conditions. Studies have found many factors contributing to urolithiasis in patients suffering from metabolic syndrome, out of which obesity, overweight, and sedentary lifestyles have been identified as major etiological factors. Primary and secondary prevention methods therefore tend to revolve mainly around lifestyle improvements, including dietary and other preventive measures.

Objective: To evaluate the relationship among urolithiasis, metabolic syndrome (MetS) and serum testosterone (T) level in men. Material and Methods: 513 men older than 18 years were enrolled in this study: 313 of the subjects had a history of stones (group 1) and 200 had no history of stones (controls, group 2). Early morning T levels were recorded and anthropometric measurements were invastigated to evaluate MetS. Analyses were completed using chi-square tests. Result: Serum T level was lower in stone forming patients than coltrol subjects and 161 (%51.4) men in group 1 and 92 (%46) men in group 2 were diagnosed with metabolic syndrome. T level was found lower limit (< 285 ng/dl) in the MetS and urolithiasis group (p 0.002, OR 2.71). Conclusions: We found low testosterone levels in the patients with stone disease and prevalance of the MetS in men with urolithiasis was higher than in men without stone disease. Our findings show that levels of testosterone had no effect on stone formation, but the factors that cause stone formation can have an effect on the level of testosterone.

Objective: Spexin (SPX) is a novel peptide implicated in food intake and satiety. Spexin levels are reduced in obese patients. Aim: To compare serum SPX levels in obese adolescents versus healthy controls and to assess the associations of metabolic syndrome (metS) antecedents with serum SPX levels. Methods: Eighty consecutive obese adolescents aged 10-18 years and 80 healthy peers were enrolled. Anthropometric measurements, pubertal examinations and clinical blood pressure measurements were performed. Fasting blood samples were drawn for glucose, insulin, lipids, uric acid, alanine aminotransferase (ALT) and SPX. Metabolic syndrome (metS) was diagnosed using International Diabetes Federation criteria. Associations of serum SPX with clinical and laboratory variables were assessed. Results: Obese adolescents had lower serum SPX levels than healthy peers (50 pg/mL [25%-75% IQR: 25-98 pg/mL] and 67.0 pg/mL [25%-75% IQR:32.5-126.0 pg/mL; respectively], p =0.035). Twenty (25 %) obese adolescents were diagnosed as having metS. Obese adolescents with metS had lower SPX than those without metS (24.5 pg/mL [25%-75% IQR: 15.3-49.5 pg/mL] and 69.0 pg/mL [25%-75% IQR: 42.0-142.0 pg/mL]; respectively p<0.0001). The frequencies of hyperuricemia, IR and elevated ALT were similar in obese adolescents with metS and those without metS (p > 0.05 for all). Serum uric acid levels were correlated significantly with serum SPX after correcting for BMI and HOMA-IR (r =-0.41, p<0.05). A serum SPX level at a cut -off level of 49.5 pg/mL predicted the presence of metS in obese adolecents with 75 % sensitivity and 71 % specifity. Conclusions: Obese adolescents have reduced SPX levels, and this reduction is more pronounced in those with metS. Further research is needed to verify the utility of SPX as a biomarker in the diagnosis of metS in obese adolescents.

Nephrolithiasis has been increasing over the last millennium. Although early epidemiologic studies have shown that kidney stones were two to three times more frequent in males than in females, recent reports have suggested that this rate is decreasing. In parallel a dramatic increase of nephrolithiasis has also been observed among children and adolescents. Furthermore, epidemiologic studies have shown a strong association between metabolic syndrome (Mets) traits and kidney stone disease. Patients with hypertension have a higher risk of stone formation and stone formers are predisposed to develop hypertension compared to the general population. An incidence of nephrolithiasis greater than 75% has been shown in overweight and obese patients compared to those of normal weight. It has also been reported that a previous diagnosis of diabetes mellitus increases the risk of future nephrolithiasis. Additionally, an association between metabolic syndrome and uric acid stone formation has been clearly recognized. Furthermore, 24-h urinary metabolic abnormalities have been decreasing among patients with nephrolithiasis over the last decades. Finally, nephrolithiasis could cause chronic kidney disease (CKD) and end stage renal disease (ESRD), especially in women and overweight patients. According to these observations, a better understanding of these new features among stone former patients may be required. Hence, the recognition and the correction of metabolic disorders could help not only to reduce the primary disease, but also stone recurrence.

Introduction: The global prevalence of metabolic syndrome (MS) among people living with HIV/AIDS varies from 20% to 33%. Objective: to estimate the prevalence of metabolic syndrome and associated factors in a group of HIV-infected patients on antiretroviral therapy. Methods: This is a cross-sectional study with HIV-infected patients from a reference center in Bahia, Brazil. We evaluated clinical, socio-demographic and anthropometric data. MS was defined according to the guidelines of International Diabetes Federation. Results: We evaluated 152 patients with mean age of 47.3±11.6 years, 59.2% male. The main comorbidities detected were diabetes (3.3%) hypertriglyceridemia (9.3%) and metabolic syndrome (MS,38.2%). Patients with MS were predominantly women (55.2% vs 31.9%; p=0.005), older [52.1 (10.4) vs 44.3 (11.3); p<0.001], and had overweight (74.1% vs 23.4%; p<0.001). After multivariate analysis MS remained associated with age (OR = 1.076; 95% CI: 1.030 – 1.125), female sex (OR = 2.452; 95% CI: 1.114 – 5.374) and family history of hypertension (OR = 3.678; 95% CI: 1.431 – 9.395). Conclusion: Almost half of the HIV-infected patients in Bahia presents with MS which seems to be driven by classical risk factors.

Abstract Background Understanding the causes and risk factors of metabolic syndrome is important for promoting population health. Oxidative stress has been associated with metabolic syndrome, and also obstructive sleep apnea. These are two diseases which have common prognostic characteristics for heart disease. The aim of this study was to examine the role of oxidative stress in the concurrent presence of metabolic syndrome and obstructive sleep apnea in a working population. Methods Participants were 163 artisan bakers in Shahroud, Iran, routinely exposed to significant heat stress and other oxidative stress indicators on a daily basis as part of their work. Using a cross-sectional design, data relevant to determining metabolic syndrome status according to International Diabetes Federation criteria, and the presence of obstructive sleep apnea according to the STOP-Bang score, was collected. Analyses included hierarchical binary logistic regression to yield predictors of the two diseases. Results Hierarchical binary logistic regression showed that oxidative stress – alongside obesity, no regular exercise, and smoking – was an independent predictor of metabolic syndrome, but not obstructive sleep apnea. Participants who were obese were 28 times more likely to have metabolic syndrome (OR 28.59, 95% CI 4.91–63.02) and 44 times more likely to have obstructive sleep apnea (OR 44.48, 95% CI 4.91–403.28). Participants meeting metabolic syndrome criteria had significantly higher levels of malondialdehyde (p <  0.05) than those who did not. No difference in oxidative stress index levels were found according to obstructive sleep apnea status. Conclusions Our findings suggest that oxidative stress contributes to the onset of metabolic syndrome, and that obstructive sleep apnea is involved in oxidative stress. Whilst obesity, exercise, and smoking remain important targets for reducing the incidence of metabolic syndrome and obstructive sleep apnea, policies to control risks of prolonged exposure to oxidative stress are also relevant in occupations where such environmental conditions exist.

The Metabolic Syndrome

Abstract Context Bardet-Biedl syndrome (BBS) is a rare autosomal recessive disorder in which previous reports have described obesity and a metabolic syndrome. Objective We describe the endocrine and metabolic characteristics of a large BBS population compared with matched control subjects. Design We performed a case-control study. Setting This study was performed at a hospital clinic. Patients Study patients had a clinical or genetic diagnosis of BBS. Main Outcome Measurements Our study determined the prevalence of a metabolic syndrome in our cohort. Results A total of 152 subjects were studied. Eighty-four (55.3%) were male. Mean (± standard deviation) age was 33.2 ± 1.0 years. Compared with age-, sex-, and body mass index–matched control subjects, fasting glucose and insulin levels were significantly higher in subjects with BBS (glucose: BBS, 5.2 ± 1.2 mmol/L vs control, 4.9 ± 0.9 mmol/L, P = 0.04; insulin: BBS, 24.2 ± 17.0 pmol/L vs control, 14.2 ± 14.8 pmol/L, P &lt; 0.001). Serum triglycerides were significantly higher in subjects with BBS (2.0 ± 1.2 mmol/L) compared with control subjects (1.3 ± 0.8 mmol/L; P &lt; 0.001), but total cholesterol, high-density lipoprotein, and low-density lipoprotein were similar in both groups. Systolic blood pressure was higher in the BBS group (BBS, 135 ± 18 mm Hg vs control subjects, 129 ± 16 mm Hg; P = 0.02). Alanine transaminase was raised in 34 (26.8%) subjects with BBS, compared with five (8.9%) control subjects (P = 0.01). The rate of metabolic syndrome, determined using International Diabetes Federation criteria, was significantly higher in the BBS group (54.3%) compared with control subjects (26% P &lt; 0.001). Twenty-six (19.5%) of male subjects with BBS were hypogonadal (serum testosterone, 9.9 ± 5.3 mmol/L), but significant pituitary abnormalities were uncommon. Subclinical hypothyroidism was present in 24 of 125 (19.4%) patients with BBS, compared with 3 of 65 (4.6%) control subjects (P = 0.01). Conclusions Insulin resistance and the metabolic syndrome are increased in adult patients with BBS compared with matched control subjects. Increased subclinical hypothyroidism in the BBS cohort needs further investigation.
