25-Hydroxy-vitamin D level may predict presence of coronary collaterals in patients with chronic coronary total occlusion

Correlational study on the levels of 25-hydroxyvitamin D and non-alcoholic fatty liver disease in type 2 diabetic patients

BACKGROUND

It is widely acknowledged that nonalcoholic fatty liver disease (NAFLD) and type 2 diabetes mellitus(T2DM) are all chronic metabolic diseases. The objective of this study is to retrospectively probe the association between the 25-hydroxyvitamin D (25-(OH)D) and NAFLD in type 2 diabetic patients.

METHODS

Three hundred thirty-nine T2DM patients participated in this research and from November 2018 to September 2019 and were divided into simple T2DM group (108 cases) and T2DM with NAFLD group (231 cases) in conformity with abdominal ultrasound diagnosis. The NAFLD fibrosis score (NFS) ≥0.676 was defined as progressive liver fibrosis.231 T2DM with NAFLD patients were categorized into two subgroups: progressive liver fibrosis subgroup (48 cases) and without progressive liver fibrosis subgroup (183 cases).

RESULTS

The prevalence of NAFLD by Abdominal ultrasonography was 68%.The results indicated that the levels of 25-(OH) D were significantly lower in T2DM with NAFLD group than that in simple T2DM group(P < 0.01). The levels of 25-(OH) D were significantly lower in progressive liver fibrosis subgroup than that in patients without progressive liver fibrosis and simple T2DM,and 25-(OH) D levels were lower in without progressive liver fibrosis subgroup than that in simple T2DM group(p < 0.01 or p < 0.05). Multivariate logistic regression analysis showed that levels of 25-(OH) D were negative correlation with risk of NAFLD and progressive liver fibrosis(p = 0.011、p = 0.044,respectively).

CONCLUSIONS

we could come to a conclusion that low levels of 25-(OH) D was a risk factor for NAFLD and progressive liver fibrosis in T2DM patients.

Impact of vitamin D level on glycemic control in diabetes mellitus type 2 in Duhok

Background

Vitamin D deficiency is prevalent in most parts of the world. Its insufficiency or deficiency is implicated in bone diseases, some cancers, infectious diseases, heart disease, autoimmune and metabolic diseases including type 2 diabetes mellitus.

Results

The mean age of patients was 49.94 ± 9.36, while the mean age the controls was 48.95 ± 10.56. Females constituted 56.1% and males 43.9% in the cases group, while for the control group females were 54.8% and males were 43.9%. Low vitamin D levels were detected in 110 (71%) of cases and 63 (40.6%) of controls. There was a significant difference in vitamin D levels among cases and controls (p < 0.001), vitamin D level was lower among females compared to males, p < 0.001 and those living in urban areas compared to rural areas, p < 0.001, BMI and dyslipidemia had a significant effect on vitamin D levels among diabetics, p values 0.002 and < 0.001 respectively. The serum 25(OH)-D level was significantly lower in patients with poor glycemic control compared to those with good glycemic control and in patients with a diabetes duration greater than 5 years, p values < 0.001 and 0.002 respectively. No significant correlation was detected with age and smoking, p values 0.181 and 0.260 respectively.

Conclusion

There is a high prevalence of hypo-vitaminosis D among patients with type-2 diabetes, particularly among patients with poor glycemic control and in those with longer diabetes durations. Vitamin-D deficiency is more prevalence in females, and those living in urban areas, those with obesity and patients with dyslipidemia.

•

Vitamin D deficiency is prevalent in most parts of the world.

•

There is a high prevalence of hypovitaminosis D among patients with type 2 diabetes.

•

Vitamin D deficiency is implicated many diseases including type 2 diabetes mellitus.

Association between ischemic heart disease and systemic lupus erythematosus-a large case-control study

Ischemic heart disease (IHD) is a well identified cause of mortality in systemic lupus erythematosus (SLE) patients due to an accelerated premature atherosclerosis. We investigated the proportion of comorbid IHD among SLE patients derived from a large, national real-life database. Using data from the largest HMO in Israel, the Clalit Health Services, we selected for patients with SLE. These patients were compared with age and sex matched controls with regards to the proportion of IHD in a case-control study. Chi-square and t tests were used for univariate analysis, and a logistic regression model was used for multivariate analysis. The study included 5018 patients with SLE and 25090 age and sex-frequency matched controls. The prevalence of IHD in patients with SLE was increased in comparison to controls (11.3 and 3.1%, P < 0.001). In a multivariate analysis, SLE was associated with IHD (OR 3.77, 95% confidence interval 3.34-4.26). We have confirmed that SLE patients suffer a high prevalence of IHD. Our data supports that SLE is an independent risk factor for IHD. When evaluating by gender, the risk seems even more substantial in females. No significant difference was found in the risk of IHD in SLE among the difference socioeconomic strata.

Role of Vitamin D in Cardiovascular Diseases

Vitamin D is critical in mineral homeostasis and skeletal health and plays a regulatory role in nonskeletal tissues. Vitamin D deficiency is associated with chronic inflammatory diseases, including diabetes and obesity, both strong risk factors for cardiovascular diseases (CVDs). CVDs, including coronary artery disease, myocardial infarction, hypertrophy, cardiomyopathy, cardiac fibrosis, heart failure, aneurysm, peripheral arterial disease, hypertension, and atherosclerosis, are major causes of morbidity and mortality. The association of these diseases with vitamin D deficiency and improvement with vitamin D supplementation suggest its therapeutic benefit. The authors review the findings on the association of vitamin D deficiency and CVDs.
