BACKGROUND: There is little information about circannual rhythm of vitamin D level in kidney transplantation (KTx) patients. MATERIAL AND METHODS: In 71 patients (27 females; 44 males) in the long term after KTx (5.5 ± 2.6 years) during the winter and summer months plasma concentration of 25-hydroxyvitamin D (25(OH)D), 1,25-hydroxyvitamin D, parathormone (PTH), fibroblast growth factor 23 (FGF-23), calcium, and phosphorus were assessed. Vitamin D status was classified according to 25(OH)D level (ie, insufficiency, ≤30 ng/mL; deficiency, <15 ng/mL)...

BACKGROUND: Low back pain (LBP) is the highest contributor to disability worldwide, with current intervention strategies only providing small to moderate analgesic effects. The use of vitamin D supplementation for LBP has gained interest due to its proposed anti-inflammatory and neuromodulatory properties. However, it is still unclear whether vitamin D levels differ between those with and without LBP or if vitamin D levels are associated with pain intensity. OBJECTIVES: We aim to investigate the association between vitamin D levels and LBP and to determine if vitamin D levels correlate with pain intensity in individuals with LBP...

OBJECTIVES: It is unclear whether seasonal variations in vitamin D concentrations affect the hypothalamo-pituitary-thyroid (HPT) axis. We investigated the seasonal variability of vitamin D and serum thyrotropin (TSH) levels and their inter-relationship. METHODS: Analysis of 401 patients referred with non-specific symptoms of tiredness who had simultaneous measurements of 25(OH)D3 and thyroid function. Patients were categorised according to the season of blood sampling and their vitamin D status...

OBJECTIVE: Primary hyperoxaluria type 1 (PH1) is a rare metabolic disorder of oxalate overproduction. It is associated with urolithiasis and nephrocalcinosis which progress to ESRD and systemic oxalosis. As oxalate deposits in tissues, non-parathyroid hormone (nonPTH) mediated hypercalcemia, oxalate osteopathy, primary hypothyroidism and primary hypogonadism develop. In this review, we will present a case of PH1 and provide an overview of this clinical entity and its endocrine manifestations...

BACKGROUND: Psoriasis is a common, inflammatory, chronic, relapsing skin disease. The pathogenesis is multifactorial and it is involved both innate and acquired immunity. Several studies have shown the important role of vitamin D in the pathogenesis of this disorder. In this study we have evaluated a possible correlation between vitamin D and clinical severity of psoriasis calculated with PASI score. METHODS: In this case control study we included 141 Caucasian subjects affected by moderate to severe psoriasis and 62 healthy controls...

BACKGROUND: High plasma 25-hydroxyvitamin D (25 (OH)D) concentration has been associated observationally with high risk of non-melanoma skin cancer, while many studies suggest that vitamin D could have a protective effect on cancer. The true association between vitamin D and risk of skin cancer remains unclear. OBJECTIVES: In this Mendelian randomisation study we tested the hypothesis that genetically high plasma 25(OH)D protects against non-melanoma skin cancer...

Introduction: Autosomal dominant polycystic kidney disease (ADPKD) is a genetic disease originating from a mutation in genes encoding polycystin 1 and 2. Recent evidence suggests that these polycystins mediate mechanosensation not only in the primary cilium of kidney cells but also in bone cells. The Wnt/β-catenin signaling pathway plays a central role in mechanotransduction in osteocytes. Mechanical unloading causes the upregulation of the Wnt inhibitor sclerostin. We tested the hypothesis that ADPKD associates with higher circulating sclerostin levels...

There is substantial evidence that the prevalence of vitamin D deficiency is unacceptably high in the population, and this requires action from a public health perspective. Circulating 25-hydroxyvitamin D [25(OH)D] is a robust and reliable marker of vitamin D status and has been used by numerous agencies in the establishment of vitamin D dietary requirements and for population surveillance of vitamin D deficiency or inadequacy. In a wider context, modeling of serum 25(OH)D data and its contributory sources, namely dietary vitamin D supply and UVB availability, can inform our understanding of population vitamin D status...

BACKGROUND: Vitamin D deficiency is implicated in some diseases, including cardiovascular. Few studies have assessed the correlation between 25-hydroxyvitamin D3 [25(OH) D3] and serum lipids. In this study, we explored the correlation between serum 25(OH) D3 concentrations and serum lipids with a typical sample of the rural population in China. METHODS: Face-to-face research was used to gather some basic information. Fasting serum concentrations of 25-(OH) D3, total cholesterol (TC), triglyceride (TG), HDL cholesterol (HDL-C) and, LDL cholesterol (LDL-C) tested in the laboratory...

Vitamin D has an important role in early life; however, the optimal vitamin D status during pregnancy is currently unclear. There have been recent calls for pregnant women to maintain circulating 25-hydroxyvitamin D (25(OH)D) concentrations >100 nmol/L for health, yet little is known about the long-term potential benefits or safety of achieving such high maternal 25(OH)D concentrations for infant or child health outcomes. We examined maternal vitamin D status and its associations with infant anthropometric and later childhood neurocognitive outcomes in a mother-child cohort in a sun-rich country near the equator (4...

BACKGROUND/AIMS: Vitamin D deficiency has become endemic globally and its etiology is complex. Few studies have investigated the determinants of serum 25-hydroxy vitamin D (25-OH D). The aim of this study was to investigate the association between lifestyle patterns, liver functional tests (LFTs), and the presence of irritable bowel syndrome (IBS) with serum 25-OH D in apparently healthy girls. METHODS: This cross-sectional study was undertaken in 965 adolescent girls aged 12-18 years...

There is a high prevalence of vitamin D insufficiency and deficiency worldwide likely because of both limited sun-exposure and inadequate dietary intake. Meat, including pork, is not typically considered a dietary source of vitamin D, possibly because of management practices that raise pigs in confinement. This experiment determined the vitamin D content of loin and subcutaneous adipose tissue in sun-exposed finisher pigs. Two separate groups of pigs were used. The first group (28 white Landrace-Duroc) was assigned at random to either sunlight exposure (SUN) in spring and summer or confinement per standard practice (Control)...

BACKGROUND: Vitamin D deficiency is a risk factor for hypertension. METHODS: We assessed 8155 participants in a community-based program to investigate the association between serum 25-hydroxyvitamin D (25(OH)D) status and blood pressure (BP) and the influence of vitamin D supplementation on hypertension. Participants were provided vitamin D supplements to reach a target serum 25(OH)D > 100 nmol/L. A nested case-control study was conducted to examine the effect of achieving physiological vitamin D status in those who were hypertensive and not taking BP-lowering medication, and hypertensive participants that initiated BP-lowering medication after program entry...

INTRODUCTION: Vascular calcification (VC) in hemodialysis (HD) patients is a sign of severe cardiovascular disease and can predict cardiovascular outcomes. Fetuin-A and osteopontin (OPN) inhibit VC. Serum fetuin-A levels are lower in patients with end-stage kidney disease (ESKD) and in those who are on chronic HD therapy. However, there are limited data concerning OPN in patients who are on dialysis. The aim of our study was to determine VC in HD patients, the relationship between VC and 25-OH-vitamin D, fetuin-A, and OPN levels, and independent predictors of VC...

Serum parathyroid hormone (PTH) was associated with increased bone turnover markers and cortical porosity of the inner transitional zone at the proximal femur. These results suggest that PTH through increased intracortical bone turnover leads to trabecularisation of inner cortical bone in postmenopausal women. INTRODUCTION: Vitamin D deficiency leads to secondary hyperparathyroidism and increased risk for fractures, whereas its association with cortical porosity is less clear. We tested (i) whether serum 25-hydroxyvitamin D (25(OH)D) and PTH were associated with cortical porosity and (ii) whether the associations of 25(OH)D) and PTH with fracture risk are dependent on cortical porosity...
