Is calcifediol better than cholecalciferol for vitamin D supplementation?

AbstractModest and even severe vitamin D deficiency is widely prevalent around the world. There is consensus that a good vitamin D status is necessary for bone and general health. Similarly, a better vitamin D status is essential for optimal efficacy of antiresorptive treatments. Supplementation of food with vitamin D or using vitamin D supplements is the most widely used strategy to improve the vitamin status. Cholecalciferol (vitamin D3) and ergocalciferol (vitamin D2) are the most widely used compounds and the relative use of both products depends on historical or practical reasons. Oral intake of calcifediol (25OHD3) rather than vitamin D itself should also be considered for oral supplementation. We reviewed all publications dealing with a comparison of oral cholecalciferol with oral calcifediol as to define the relative efficacy of both compounds for improving the vitamin D status. First, oral calcifediol results in a more rapid increase in serum 25OHD compared to oral cholecalciferol. Second, oral calcifediol is more potent than cholecalciferol, so that lower dosages are needed. Based on the results of nine RCTs comparing physiologic doses of oral cholecalciferol with oral calcifediol, calcifediol was 3.2-fold more potent than oral cholecalciferol. Indeed, when using dosages ≤ 25 μg/day, serum 25OHD increased by 1.5 ± 0.9 nmol/l for each 1 μg cholecalciferol, whereas this was 4.8 ± 1.2 nmol/l ...

Authors: Manavi KR, Alston-Mills BP, Thompson MP Abstract Tobacco usage kills more than 8 million people a year. Approximately 7 million of those deaths are the result of direct tobacco use, while approximately 1.2 million are the result of non-smokers being exposed to second-hand smoke. About 200 million of the world's one billion smokers are women and usage among women is increasing in some countries. Nicotine from smoking tobacco, specifically its metabolite cotinine, has negative effects on human health causing lung cancer, COPD and non-respiratory problems. Over a billion people worldwide are Vitamin D defici...

(The North American Menopause Society (NAMS)) Lumbar disc degeneration and resulting lower back pain become greater concerns with age and disproportionately affect women more than men, likely as a result of decreasing estrogen levels during menopause. A new study demonstrates that vitamin D deficiency, smoking, high body mass index (BMI), and osteoporosis are risk factors for greater back pain. Study results are published online today in Menopause, the journal of The North American Menopause Society (NAMS).

In this study, we aimed to investigate the effect of propionate on the expression of the vitamin D receptor (VDR) in the small intestine of rats with SBS. Firstly, IEC-6 (intestinal epithelioid cell line No. 6) cells were incubated in vitro with 1 mM sodium propionate for 24 h. This resulted in a significant increase in the expression of VDR and yes-associated protein (YAP) compared with that in the control group. Transfection of IEC-6 cells with YAP siRNA significantly down-regulated the expression of VDR. By contrast, after incubating IEC-6 cells with lysophosphatidic acid, an agonist of YAP, upr...

Authors: Gatti D, Fassio A Abstract Osteoporosis is a common disease that increases fracture risk. Fragility fractures bring heavy consequences in terms of mortality and disability, with burdensome health and social costs. In subjects with clinical bone fragility, the first goal is to identify the secondary forms of osteoporosis, especially in young subjects, in males and in patients who recently experienced a fragility fracture. In addition, before considering any sort of treatment, it is fundamental to check for adequate calcium and vitamin D intake, since their deficiency is the most common reason for drug failu...

This study aimed to present a rare case of pathological fracture of femur in Alagille syndrome patient and its management in our hospital.Six-year-old male with pain on his right thigh came to our ER after fell down while putting on his pants. He had been diagnosed with biliary atresia at the age of 3 months and underwent surgical bile duct reconstruction. In addition, he also suffered from congenital hypothyroidism and consequently, stunted growth. The pathological fracture of the femur was treated conservatively with hemispica cast. At 2 months follow up, there is already radiographic evidence of fracture healing occurre...

Authors: Zelenka L, Knížková I, Lukešová D, Kunc P Abstract PURPOSE OF THE STUDY The pilot study deals with the current situation in proximal femoral fractures in culturally diverse regions, namely in Afghanistan (AFG) and in the Czech Republic (CZ). The study aimed to find out whether there are any differences in proximal femoral fractures in dependence on the selected criteria between the two culturally diverse areas. The study used the data of patients who underwent surgery for proximal femoral fracture at the Department of Orthopaedics of the 1 s t Medical Faculty of the Charles Uni...

Neuromuscular diseases (NMDs) are inherited or acquired conditions affecting skeletal muscles, motor nerves, or neuromuscular junctions. Most of them are characterized by a progressive damage of muscle fibers with reduced muscle strength, disability, and poor health-related quality of life of affected patients. In this scenario, skeletal health is usually compromised as a consequence of modified bone–muscle cross-talk including biomechanical and bio-humoral issues, resulting in increased risk of bone fragility and fractures. In addition, NMD patients frequently face nutritional issues, including malnutrition due to f...

Background: Osteoporosis is an important extra-pulmonary manifestation of chronic obstructive pulmonary disease (COPD).Aim: To evaluate the prevalence of osteoporosis, osteopenia and vitamin D deficiency in patients with moderate to very severe COPD, and to explore the association between bone mineral density (BMD) and exercise capacity / gait speed.Methods: BMD and T-score were measured by the dual energy X-ray absorptiometry, and serum level of 25-hydroxyvitamin D was determined. Severity of COPD was evaluated by the pulmonary functions tests, COPD Assessment Test, and modified Medical Research dyspnoea scale. Six-minute...

AbstractAthletes should pay more attention to their bone health, whether this relates to their longer-term bone health (e.g. risk of osteopenia and osteoporosis) or their shorter-term risk of bony injuries. Perhaps the easiest way to do this would be to modify their training loads, although this advice rarely seems popular with coaches and athletes for obvious reasons. As such, other possibilities to support the athletes ’ bone health need to be explored. Given that bone is a nutritionally modified tissue and diet has a significant influence on bone health across the lifespan, diet and nutritional composition seem li...
