Vitamin D has gotten a lot of press over the years. But is it actually worth the hype, especially when it comes to autoimmunity? Does it prevent the onset of autoimmune disease? Does it have a role in treatment? Experts in this ACR Convergence 2024 session helped decipher the role of vitamin D in bone health, immune regulation and infection reduction.
Supplemental vitamin D may not significantly lower the risk of fractures in generally healthy adults compared with placebo, according to a large study by LeBoff et al.
(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…
(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…
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…
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…
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…
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…
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…
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…
