In reports that showed benefit purchase amitriptyline 25mg on line depression test for 14 year old, the results became apparent after 3 to 4 months of supplementation. The study size was small with 19 subjects in the treatment group and 18 subjects in the placebo control group. Although no patients withdrew from the study because of adverse effects, a 28% withdrawal rate was observed in each group, perhaps because of the large number of capsules administered. There was no statistically significant improvement in the primary end point of fatigue. Consumption of borage seeds is not recom- mended during pregnancy and lactation due to potential contamination with liver-toxic pyrrolizidine alkaloids (45). Vitamins Vitamins are organic compounds that are required in small amounts for normal metabolism. The human body does not synthesize vitamins, except for vitamin D; therefore, vitamins must be ingested in the diet. Therefore, vitamin supplementation has been promoted for good health and as a preventive measure against certain ailments. The evidence for vitamin supplemen- tation in rheumatic conditions is reviewed in the following section. Vitamin C is important for the growth, development, and enzymatic reactions of bone and cartilage. Vitamin C acts as an antioxidant in facili- tating the hydroxylation of proline and lysine to hydroxyproline and hydroxylysine in procollagen. These products are essential to the maturation of collagen molecules and, thus, to the construction of the extracellular matrix of cartilage. This may be related to alterations in enzymatic activity or reduc- tions in proline hydroxylation or both (52). It was hypothesized, because animals receiving higher doses had higher cartilages weights, that vitamin C protected against cartilage loss by stimulating collagen synthesis (53). However, more recent work has suggested that long-term exposure to vitamin C supplementation might have deleterious effects (54). Guinea pigs were supplemented with low, medium, and high doses of vitamin C for 8 months. On subsequent histological evaluation, the animals that had received the medium and high doses had more severe histological changes, including the formation of osteo- phytes. The investigators hypothesized that the process of chondrophyte formation, with evolution into osteophytes, may have been facilitated by the enhanced collagen synthesis afforded by higher doses of ascorbic acid. On the basis of the most recent guinea pig data, it has been suggested that vitamin C supplementation above the currently recommended daily doses of 75 to 90 mg not be advised (54). The only human data comes from an epidemiological investigation using the Framingham population (55). This relationship was statistically significant in men and African Americans, but not for women or other ethnic groups among 400 participants studied. There was no difference in medial or lateral tibial cartilage volume loss between the vitamin E-supplemented group and those who got placebo at the end of the trial. Furthermore, there was no relationship between dietary levels of antioxidants and cartilage volume loss. It is an essential cofactor in the formation of skeletal matrix proteins containing the -carboxyglutamic acid residue. These proteins have high affinity for calcium and phosphate allowing for mineralization of skeletal tissue. Insufficient vitamin K can lead to abnormal chondrocyte differentiation and endochondral bone formation (58,59). The vitamin-K dependent bone and cartilage proteins can inhibit excessive extracellular matrix calcifications believed to be responsible for abnormal osteophyte formation in osteoarthritis. This statistically significant effect was seen in the radiographs of the hands and knees of a cohort of 672 subjects (59). Glucosamine is an aminomonosac- charide that is a component of glycoproteins, proteoglycans, and glycosaminoglycans. Glucosamine and chondroitin levels are reduced or altered in osteoarthritic cartilage and synovial fluid (61,62). Therefore, the notion of replenishing these agents through dietary intake in order to reduce joint symptoms has been proposed. Orally administered glucosamine is detectable at low levels in the sera of human subjects, but there has been no direct demonstration that glucosamine is incorporated into cartilage (63). In the subjects who took 1,500 mg of glucosamine sulfate mixed with water, the serum glucosamine levels reached a maximum of 4. Based on the low serum levels achieved, the investigators concluded that it was unlikely that glucosamine contributed to proteoglycan synthesis in vivo. In addition to simply serving as building blocks of cartilage, glucosamine and chondrointin might affect the metabolism of cartilage constituents. It was shown in in vitro studies that glucosamine could stimulate proteoglycan synthesis by human chondrocytes and become incorporated into glycosaminoglycans (62,64). In animal studies, glucosamine reduced cellular production of inflammatory mediators and inflammation (65). Although the majority of earlier trials seem to suggest modest benefit in terms of pain relief as well as objective improvements, more recent meta- analyses of the studies indicated that the benefits might not be as great. One of the most widely cited clinical trials that showed benefits of glucosamine was carried out in Europe. At the end of the trial, the subjects who were treated with glucosamine had an average of 11. Overall, when compared with placebo, glucosamine showed a 28% improvement in pain and 21% improvement in function using the Lequesne Index.
