AI Article Synopsis

  • PCOS is a common endocrine disorder in women of childbearing age, with a significant number (28% to 46%) also experiencing metabolic syndrome, which is linked to non-alcoholic fatty liver disease (NAFLD).
  • A study involving 131 women (101 with PCOS and 30 controls) aimed to determine the prevalence of NAFLD and metabolic syndrome in PCOS patients and explore any correlations between the two.
  • Results showed that NAFLD was present in 23.8% of the PCOS group compared to 3.3% in controls, and metabolic syndrome was diagnosed in about one-third of the PCOS patients, indicating a notable association between PCOS and these metabolic conditions.

Article Abstract

Background: The polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders in women at childbearing age. Metabolic syndrome is present from 28% to 46% of patients with PCOS. Non-alcoholic fatty liver disease (NAFLD) is considered the hepatic expression of metabolic syndrome. There are few published studies that correlate PCOS and NAFLD.

Objective: To determine the prevalence of NAFLD and metabolic syndrome in patients with PCOS, and to verify if there is a correlation between NAFLD and metabolic syndrome in this population.

Methods: Study developed at Gynecology Department of Clinical Hospital of Federal University of Parana (UFPR). The sessions were conducted from April 2008 to January 2009. One hundred and thirty-one patients joined the analysis; 101 were diagnosed with PCOS and 30 formed the control group. We subdivided the PCOS patients into two subgroups: PCOS+NAFLD and PCOS. All the patients were submitted to hepatic sonography. For hepatoestheatosis screening, hepatic ecotexture was compared do spleen's. For diagnosis of metabolic syndrome, we adopted the National Cholesterol Education Program/Adult Treatment Panel III (NCEP/ATP III) criteria, as well as the criteria proposed by International Diabetes Federation. Statistical analysis were performed with t of student and U of Mann-Whitney test for means and chi square for proportions.

Results: At PCOS group, NAFLD was present in 23.8% of the population. At control group, it represented 3.3%, with statistical significance (P=0.01). Metabolic syndrome, by NCEP/ATP III criteria, was diagnosed in 32.7% of the women with PCOS and in 26.6% of the women at control group (no statistical difference, P=0.5). At PCOS+DHGNA subgroup, age, weight, BMI, abdominal circumference and glucose tolerance test results were higher when compared to PCOS group (P<0.01). Metabolic syndrome by NCEP/ATPIII criteria was present in 75% and by International Diabetes Federation criteria in 95.8% of women with PCOS+NAFLD with P<0.01. Insulin levels at SOP+DHGNA were higher than at PCOS group with P<0.01.

Conclusion: Almost 25% of the patients with PCOS were diagnosed for NAFLD. Metabolic syndrome was present between 32.7% and 44.6% of patients with PCOS. At subgroup PCOS+NAFLD, metabolic syndrome is highly prevalent. These patients are more obese, with higher BMI and higher glucose levels.

Cancer survivors have an increased risk of developing Type 2 diabetes compared to the general population. Patients treated with cisplatin, a common chemotherapeutic agent, are more likely to develop metabolic syndrome and Type 2 diabetes than age- and sex-matched controls. Surprisingly, the impact of cisplatin on pancreatic islets has not been reported.

Background: Obesity and metabolic syndrome (MS) accelerate arterial stiffening, increasing cardiovascular (CV) risk after transplant. BMI is limited by inability to differentiate muscle, fat mass, and fat distribution patterns. The aim of this study was to identify the best anthropometric measure to detect arterial stiffness as assessed by pulse wave velocity (PWV) in a racially diverse pediatric transplant population.

The present investigation evaluated the potential impacts of morin, a natural flavonoid, against cardiovascular disorders. Since inception until September 2024, PubMed, Scopus, and Web of Science have been searched extensively. The process involved eliminating duplicate entries and conducting a systematic review of the remaining studies post-full-text screening.

Alagille syndrome (ALGS) is a rare, cholestatic multiorgan disease associated with bile duct paucity, leading to cholestasis. Clinical symptoms of cholestasis include debilitating pruritus, xanthomas, fat-soluble vitamin deficiencies, growth failure, renal disease and impaired health-related quality of life (HRQoL). The main objective was to review the current literature on the epidemiological, clinical, psychosocial and economic burden of ALGS in view of the development of ileal bile acid transporter (IBAT) inhibitors.

Background: We aimed to evaluate how the parameters used in the diagnosis of metabolic syndrome (MetS) and parameters such as epicardial adipose tissue (EAT) thickness, insulin resistance (IR), and serum uric acid (SUA) are affected according to the severity of obesity.

Methods: A total of 120 obese patients aged 10-18 years were classified as class 1-2-3 according to their body mass index (BMI) score. SUA was measured and oral glucose tolerance tests were performed on all patients.
