Vitamin D deficiency is common in patients with type 2 diabetes mellitus (T2DM). Vitamin D status may have a causal role in the onset of T2DM and may influence glycaemic control in these patients. However, data on vitamin D status among Bangladeshi T2DM patients are scarce. The present cross-sectional study was done among newly diagnosed 50 T2DM patients attending outpatient department of Comilla Diabetic Hospital, Bangladesh to address this lacuna. Serum 25(OH)D was measured in all and classified as normal (≥30ng/mL), insufficient (>20 to 29...

BACKGROUND AND AIMS: Low serum 25-OH D levels are associated with increased cardiovascular morbidity and mortality. Recent studies have linked 25-OH D deficiency with the presence of CAD. Women, especially post-menopausal, tend to suffer from accelerated atherosclerosis, along with vitamin D deficiency. In the present study we sought to investigate whether there is a direct association of coronary artery luminal stenosis with 25-OH D deficiency in women. PATIENTS AND METHODS: We enrolled women aged >40 who were scheduled to undergo elective coronary angiography between 3/2011 and 10/2016 in a prospective observational study...

BACKGROUND: Osteoporosis is associated with a poor quality of life and mortality. Proteinuria contributes to vitamin D deficiency and osteoblast dysfunction. The correlation between estimated glomerular filtration rate (eGFR) and bone density still remains elusive. Therefore, we sought to investigate whether reduced eGFR or proteinuria are independently associated with the osteoporotic risk. METHODS: We conducted a cross-sectional study using community-based health survey data from January 2004 to December 2008 in southern Taiwan...

BACKGROUND: Hypertension is a major global public health issue. Uncontrolled hypertension leads to organ damage, especially renal damage. Calcitriol is used to treat osteoporosis, promote bone formation, and increase bone mass. Previous studies have demonstrated that 1,25(OH)2D3, in addition to its classic role, also has multiple immune regulation and renoprotective functions and inhibits the activity of the renin-angiotensin-aldosterone system (RASS). The aim of the current study was to investigate the renoprotective effects of calcitriol in a spontaneously hypertensive rat (SHR) model...

25-Hydroxyvitamin D (25(OH)D) deficiency is a frequent condition in patients who suffer acute ischemic stroke (AIS), and several studies suggested that it may be associated with a poorer prognosis. Whether this association is affected by hypertension is unclear. Our aim was to investigate the association between 25(OH)D levels and both clinical severity and outcome after 3 months in AIS patients stratified by the history of hypertension. Consecutive first-ever AIS patients admitted to the Third Affiliated Hospital of Sun Yat-sen University, China were identified...

Background: African Americans (AA) are at high risk for hypertension (HTN) and poor blood pressure (BP) control. Persistently elevated BP contributes to cardiovascular morbidity. White matter hyperintensities (WMH) are a definable magnetic resonance imaging (MRI) marker of cerebrovascular injury linked to impairments in higher level thinking (i.e., executive functions), memory formation and speed of perceptual-motor processing. Methods: This sub-investigation evaluated neuropsychological functioning in association with WMH on brain MRIs in 23 otherwise healthy hypertensive AAs participating in an NIH-funded study of the effects of Vitamin D on BP and cardiac remodeling in AA patients 30-74 years of age with HTN and left ventricular hypertrophy...

Reactive oxygen species (ROS) and reactive nitrogen species (RNS) play a key role in the regulation of the physiological and pathological signaling within the vasculature. In physiological conditions, a delicate balance between oxidants and antioxidants protects cells from the detrimental effects of ROS/RNS. Indeed, the imbalance between ROS/RNS production and antioxidant defense mechanisms leads to oxidative and nitrosative stress within the cell. These processes promote the vascular damage observed in chronic conditions, such as hypertension...

The role of vitamin D in the human body is not limited only to the regulation of calcium metabolism and secondary to the impact on bones. Recent studies have shown the influence of vitamin D level on muscles, on the risk of cancer, diabetes, hypertension and pulmonary diseases, including granulomatous diseases. Sarcoidosis is a granulomatous disease of unknown etiology. Hypercalcemia in the course of the disease occurs in up to 10% of cases in the consequence of autonomous overproduction of 1,25-dihydroxyvitamin D by macrophages of sarcoid granulomas...
