(Reuters Health)—Vitamin D supplementation may not improve bone density or prevent fractures and falls in adults, a large new analysis suggests. After combining data from 81 randomized controlled trials, researchers found no bone benefits from supplementing the vitamin, according to the report in The Lancet Diabetes & Endocrinology, online October 4. “Our results show that… [Read More]

Vitamin D, Calcium Supplements May Not Lower Fracture Risk
(Reuters Health)—Older adults who take vitamin D and calcium are no less likely to break their hips or other bones than peers who don’t use these supplements, a research review suggests. Researchers examined data from 33 previous trials with a total of more than 51,000 people aged 50 or older who were living in the… [Read More]
Vitamin D-Metabolite Ratio Predicts Fracture Risk Better than 25(OH)D
NEW YORK (Reuters Health)—Vitamin D-metabolite ratio (VMR) may be a better marker of bone health than 25(OH)D (25-hydroxyvitamin D), a new study suggests. “The parameter that’s currently used to assess vitamin D status, 25(OH)D, is a flawed measure because it doesn’t consistently associate with important bone outcomes like hip fractures,” Dr. Charles Ginsberg of Veterans… [Read More]
Vitamin D May Improve Outcomes for Patients with Early RA
A recent study examined the differences in T helper cell subtypes and osteoclast precursors between patients with early RA and healthy controls. Researchers found that standard treatment combined with a single dose of cholecalcipherol may better improve the general health of patients…... [Read More]
Low Levels of Vitamin D3 May Increase OA Pain
In a study of patients with knee osteoarthritis (OA), researchers found that the cytokine IL-17A may play a role in the pain associated with the disease. Specifically, decreased serum levels of vitamin D3 may contribute to OA pain via the regulation of immune responses…... [Read More]
Vitamin D May Improve Heart Health in Patients with Lupus
A new study has found that treating patients who have systemic lupus erythematosus (SLE) with vitamin D decreases cardiovascular risk in these patients—specifically by modifying the body’s endothelial repair mechanisms. Researchers found myeloid angiogenic cells in this patient population presented with a global impairment, including decreased migration and angiogenic capacity…... [Read More]
Improve RA Care with Vitamin D
Background Autoimmune diseases, such as rheumatoid arthritis (RA) and systemic lupus erythematous, occur when the body attacks its own tissue because it cannot differentiate between self and non-self. This is mainly through deregulation of the immune system. Vitamin D has been known to play a critical role in bone mineralization and bone health. Activated vitamin… [Read More]
Vitamin D in Rheumatology: Cause and Effect Unclear
The controversy over vitamin D is hearty enough to confuse even seasoned rheumatologists, says Nathan Wei, MD, The Arthritis Treatment Center, Frederick, Md. “It’s like what you hear with coffee. One week, [a study finds] coffee is … good for you; the next week, there’s a study saying it’s bad for you,” he says. Vitamin… [Read More]
Vitamin C Derivative Promising Option for OA
New research in mice has found that treatment with a vitamin C derivative can effectively suppress the generation of mitochondrial superoxide, which plays a role in cartilage degeneration and the progression of osteoarthritis…... [Read More]
Measuring Quality of Care Is Here to Stay—and the ACR Can Help
Imagine a patient comes into your office with active RA or lupus. You diagnose her and prescribe medications for her active disease—rash, arthritis, and so forth—but you do nothing to address possible long-term complications. You don’t prescribe calcium or vitamin D to prevent osteoporosis, you don’t get a bone density scan, and you don’t order labs to check risk factors for heart disease.... [Read More]
