McAlindon Summary There are numerous mechanisms by which micronutrients might be expected to influence the development or progression of osteoarthritis, but there has been insufficient research to draw definitive conclusions One observational study suggested a protective effect of vitamin C for progression of osteoarthritis of the knee. Intake of vitamin E and -carotene bore no relationship to osteoarthritis incidence or progression in that study, suggesting that the mechanism of benefit of vitamin C may be mediated through nonantioxidant properties Clinical trials of vitamins E, C, and A and selenium have produced negative or inconsistent results Epidemiological data for vitamin D in the treatment of symptoms and structural progression of osteoarthritis are conflicting. A randomized controlled trial is currently underway to address the efficacy of vitamin D in both the treatment of symptoms and structural progression in osteoarthritis. Randomized controlled trials are currently underway to address the efficacy of vitamin K in both the treatment of symptoms and structural progression in osteoarthritis. Key Words: Antioxidant micronutrients; glucosamine and chondroitin products; nutritional supplements; osteoarthritis; vitamins 1. Speculative lay publications on this subject proliferate, and health food stores offer an excess of nutritional supplements represented as therapies for arthritis (1). The over-the-counter consumption of such nutritional remedies is significant, with From: Nutrition and Health: Nutrition and Rheumatic Disease Edited by: L. Surveys suggest that 5 to 8% of adults in the United States have used at least one of these products at some time (3). Thus, there is a need for safe and effective alternative therapies as well as preventive strategies. Such processes include oxidative damage, cartilage matrix degradation and repair, and chondrocyte function and response in adjacent bone. With more advanced disease, pain may be noted with progressively less activity, eventually occurring at rest and at night. Morning stiffness typically resolves less than 30 minutes after a patient awakens, but may recur following periods of inactivity, a phenomenon termed gelling. Crepitus is a common finding and is probably caused by the disruption of the normally smooth articulating surfaces of the joints. Osteophytes may be palpable as bony enlargements along the periphery of the joint. About 1 to 2% of electrons leak from the mitochondrial respiratory chain-forming superoxide anions (5). Other endogenous sources include release by phagocytes during the oxidative burst, generated by mixed function oxidase enzymes, and in hypoxia- reperfusion events (6). Intracellular defense is provided primarily by antioxidant enzymes including super- oxide dismutase, catalase, and peroxidases. Additionally, antioxidants may have an important function in the extracellular space where antioxidant enzymes are rare (22). These include ascorbate (vitamin C), -tocopherol (vitamin E), -carotene (a vitamin A precursor), and other carotenoids. The serum concentrations of these antioxidants are primarily determined by dietary intake. In such instances, micronutrient antioxidants might provide further defense against tissue injury.
