ABSTRACT
Background: Metabolic syndrome is one of the most common public health concerns in the 21st century. Several previous studies have shown an association between increased serum ferritin levels and other components of metabolic syndrome and the risk of metabolic syndrome. They conclude that ferritin can be viewed as a predictor of metabolic syndrome risk. This study investigates some main features of metabolic syndrome and the serum ferritin levels in a Vietnamese adult cohort with metabolic syndrome. Methods: A descriptive cross-sectional study was conducted on 207 patients who were treated at the General Internal Medicine-Geriatric Department, Hue Central Hospital, from May 2018 to August 2020. Patients were divided into two groups: the study group (104 patients with metabolic syndrome) and the control group (103 patients without metabolic syndrome and no serum ferritin-mediated disease). The metabolic syndrome was diagnosed by a joint interim statement of the International Diabetes Federation/American Heart Association/National Heart, Lung, and Blood Institute/World Heart Federation/International Atherosclerosis Society/International Association for the Study of Obesity in 2009. Results: Hypertriglyceridemia-hypertension-hyperglycemia (50.9%) is the most common combination of metabolic syndrome components. The mean serum ferritin concentration was 391.62±181.97ng/mL and 124.55±63.95ng/mL in the metabolic syndrome and control groups, respectively. In the metabolic syndrome group, increased ferritin concentration accounted for 86.54% for men, the mean serum ferritin concentration was 453.064 ± 161.75ng/mL (increased ferritin concentration accounted for 96.15%) for women; the mean serum ferritin concentration was 330.17 ± 181.71 ng/mL (increased ferritin concentration accounted for 86.54%). Conclusion: The serum ferritin level is significantly increased in Vietnamese patients with metabolic syndrome.
ABSTRACT
INTRODUCTION: Clarifying the prevalence of vitamin D deficiency in diabetic patients, and the relationship between vitamin D concentration and insulin resistance, fasting plasma glucose, and HbA1C in patients in Hue City, Vietnam. METHODS: A cross-sectional study on 110 diabetic patients examined at Hue Central Hospital and Hue University of Medicine and Pharmacy Hospital. These patients were collected venous blood sampling, and the 25(OH)D test, fasting plasma glucose test, fasting insulin test, HOMA-IR and QUICKI calculation. RESULTS: Vitamin D deficiency and insufficiency prevalence were 51.8%. The average concentration of 25(OH)D (ng/mL) was 30.67 ± 8.55; this concentration in fasting glucose level ≤8 mmol/l group and >8 mmol/l group was 32.08 ± 9.26 and 28.55±6.91 (p = 0.033); it was 32.95 ± 8.58 and 28.97 ± 8.17 in HOMA-IR ≤3.5 and HOMA-IR >3.5 group, (p = 0.015); in QUICKI ≤0.32 group, it was 29.16 ± 8.12; in QUICKI >0.32 group, it was 32.85 ± 8.76 (p = 0.025). Patients with an ideal exercise level have higher average levels of 25(OH)D (32.11±8.62 vs 26.83±7.16, p=0.003). The average levels of 25(OH)D in male patients are higher than in female patients (33.47±0.08 vs 29.01±8.43, p=0.008). Vitamin D deficiency and insufficiency prevalence in patients with HOMA-IR ≤3.5 and QUICKI >0.32 were 36.2% and 37.8%, whereas in those with HOMA-IR >3.5 and QUICKI ≤0.32 they were 63.5% and 61.5% (p = 0.007 and 0.02, respectively). 25(OH)D is negative correlation with fasting glucose level and HOMA-IR, with r = -0.229 and -0.192, respectively (p = 0.016 and 0.045); 25(OH)D was positively correlated with QUICKI, with r = 0.235, p = 0.008. CONCLUSION: Patients who have better glucose-related parameters, such as fasting blood sugar, HOMA-IR and QUICKI, have a better vitamin D status. Some blood sugar-related factors, such as exercise level and sex, are related to vitamin D status.
