The Use of Glucosamine, Devil’s Claw (Harpagophytum procumbens), and Acupuncture as Complementary and Alternative Treatments for Osteoarthritis
Alternative Medicine Review 2011 (Sep); 16 (3): 228–238 ~ FULL TEXT
Osteoarthritis is one of the most common chronic inflammatory conditions seen in the general population. Current pharmacological treatments focus on reduction of pain and increased mobility to improve overall quality of life. However, the relief a"orded by current standard care is often insu#cient and can be associated with significant side effects. Many patients, therefore, seek the option of non-standard therapies, such as nutritional and herbal supplements, acupuncture, and exercise regimens. Glucosamine, Harpagophytum procumbens, and acupuncture are among the most commonly used complementary and alternative medicine approaches utilized by patients su"ering from osteoarthritis. Their clinical relevance, safety, and potential mechanisms of action are discussed in this review.
The Effect of Nutritional Supplements on Osteoarthritis
Alternative Medicine Review 2004 (Sep); 9 (3): 275–296 ~ FULL TEXT
Osteoarthritis (OA) is the most common form of joint disease and cause of musculoskeletal disability in the elderly. Conventional management of OA primarily focuses on the relief of symptoms, using agents such as analgesics and non-steroidal anti-inflammatory drugs (NSAIDs). These drugs, however, are associated with significant side effects and fail to slow the progression of OA. Several nutritional supplements have been shown to be at least as effective as NSAIDs at relieving the symptoms of OA, and preliminary evidence suggests several of these supplements may have a role in influencing the course of OA. The purpose of this article is to review the available literature on the effectiveness and safety of nutritional supplements for the treatment of OA.
Glucosamine Prevents in Vitro Collagen Degradation in Chondrocytes by Inhibiting Advanced Lipoxidation Reactions and Protein Oxidation
Arthritis Res Ther 2007 (Aug 8); 9 (4): R76
Glucosamine hydrochloride, in a dose-dependent manner, inhibited malondialdehyde (TBARS) formation by oxidized lipoproteins. Moreover, we show that glucosamine hydrochloride prevents lipoprotein protein oxidation and inhibits malondialdehyde adduct formation in chondrocyte cell matrix, suggesting that it inhibits advanced lipoxidation reactions. Together, the data suggest that the mechanism of decreasing collagen degradation in this in vitro model system by glucosamine may be mediated by the inhibition of advanced lipoxidation reaction, preventing the oxidation and loss of collagen matrix from labeled chondrocyte matrix. Further studies are needed to relate these in vitro findings to the retardation of cartilage degradation reported in OA trials investigating glucosamine.
Efficacy of Glucosamine Sulfate Treatment in Patients with Osteoarthritis
Pol Merkur Lekarski 2007 (Mar); 22 (129): 204–207
We found the significant improvement during treatment in 38 (80.85%) pts. as measured by WOMAC scale and in 36 (70.60%) as measured by Lequesne'a scale. Self assessed pain improved in 35 (74%) of patients. The efficacy of the treatment was characterized as "good" by 60% of patients, and it was similar to physician assessment (Cohen's kappa coefficient of agreement = 0.9359). No clinically significant adverse events were observed.
Structural and Symptomatic Efficacy of Glucosamine and Chondroitin in Knee Osteoarthritis: A Comprehensive Meta-analysis
Arch Intern Med 2003 (Jul 14); 163 (13): 1514–1522
Our results demonstrated a highly significant efficacy of glucosamine on all outcomes, including joint space narrowing and WOMAC. Chondroitin was found to be effective on Lequesne Index, visual analog scale pain, mobility, and responding status. Safety was excellent for both compounds.
Glucosamine and Chondroitin Sulfate Supplementation to Treat Symptomatic Disc Degeneration: Biochemical Rationale and Case Report
BMC Complement Altern Med 2003 (Jun 10); 3 (1): 2 ~ FULL TEXT
During the two years time period, improvement of the structural quality of the disc cartilage (associated with increased water content) was clearly visible by brightening of the T2-weighted MRI signal, as shown in Figure I. The L3-4 disc showed an initial protrusion, which decreased in time, while the MRI signal normalized in time. During the two years, L3-4 disc height restored slightly (5–10%). Disc L4-5 showed signs of an advanced state of degeneration, and no improvement but also no worsening of this disc (endplates morphologically unchanged) over the 2 years period. Contrary to NSAIDs, no significant adverse clinical, hematological, hemostatic or other side effects were found in any clinical study using glucosamine and/or CS supplementation.
Evaluation of Glucosamine Sulfate Compared to Ibuprofen for the Treatment of Temporomandibular Joint Osteoarthritis: A Randomized Double Blind Controlled 3 Month Clinical Trial
J Rheumatol 2001 (Jun); 28 (6): 1347–1355
Glucosamine Sulfate (GS) and ibuprofen reduce pain levels in patients with TMJ degenerative joint disease. In the subgroup that met the initial efficacy criteria, GS had a significantly greater influence in reducing pain produced during function and effect of pain with daily activities. GS has a carryover effect.
Long-term Effects of Glucosamine Sulphate on Osteoarthritis Progression: A Randomised, Placebo-controlled Clinical Trial
Lancet 2001 (Jan 27); 357 (9252): 251–256 ~ FULL TEXT
In this recent study published in Lancet, researchers evaluated 1,500 mg/day glucosamine sulfate on the progression of osteoarthritic joint-structure changes and symptoms in 212 participants. The researchers found glucosamine sulfate improved both the symptoms and structural changes associated with OA.
Glucosamine and Chondroitin for Treatment of Osteoarthritis:
A Systematic Quality Assessment and Meta–analysis
JAMA 2000 (Mar 15); 283 (11):1469-1475
Trials of glucosamine and chondroitin preparations for OA symptoms demonstrate moderate to large effects, but quality issues and likely publication bias suggest that these effects are exaggerated. Nevertheless, some degree of efficacy appears probable for these preparations.
Natural Treatments for Osteoarthritis
Alternative Medicine Review 1999 (Oct); 4 (5): 330–341 ~ FULL TEXT
Osteoarthritis (OA) is the most common form of joint disease. Although OA was previously thought to be a progressive, degenerative disorder, it is now known that spontaneous arrest or reversal of the disease can occur. Conventional medications are often effective for symptom relief, but they can also cause significant side effects and do not slow the progression of the disease. Several natural substances have been shown to be at least as effective as nonsteroidal anti-inflammatory drugs at relieving the symptoms of OA, and preliminary evidence suggests some of these compounds may exert a favorable influence on the course of the disease.
Glucosamine Sulfate Monograph
Alternative Medicine Review 1999 (Jun); 4 (3): 193–195 ~ FULL TEXT
Glucosamine sulfate's role in halting or reversing joint degeneration appears to be directly due to its ability to act as an essential substrate for, and to stimulate the biosynthesis of, the glycosaminoglycans and the hyaluronic acid backbone needed for the formation of the proteoglycans found in the structural matrix of joints. Successful treatment of osteoarthritis must effectively control pain and should slow down or reverse the progression of the degeneration. Biochemical and pharmacological data combined with animal and human studies demonstrate that glucosamine sulfate is capable of satisfying both of these criteria.
Efficacy and Safety of Glucosamine Sulfate versus Ibuprofen in Patients with Knee Osteoarthritis
Arzneimittelforschung 1998 (May); 48 (5): 469–474
GS was significantly better tolerated than IBU, as shown by the adverse drug reactions (6% in the patients of the GS group and 16% in the IBU group--p = 0.02) and by the drug-related drop-outs (0% of the patients in the GS group and 10% in the IBU group--p = 0.0017). The better tolerability of GS is explained by its mode of action, because GS specifically curbs the pathogenic mechanisms of osteoarthritis and does not inhibit the cyclo-oxygenases as the non-steroidal anti-inflammatory drugs (NSAIDs) do, with the consequent anti-inflammatory analgesic activities but also with the several adverse reactions due to this not targeted effect.
The Role of Glucosamine Sulfate and Chondroitin Sulfates in the Treatment of Degenerative Joint Disease
Alternative Medicine Review 1998 (Feb); 3 (1): 27–39
Successful treatment of osteoarthritis must effectively control pain, and should slow down or reverse progression of the disease. Biochemical and pharmacological data combined with animal and human studies demonstrate glucosamine sulfate is capable of satisfying these criteria. Glucosamine sulfate's primary biological role in halting or reversing joint degeneration appears to be directly due to its ability to act as an essential substrate for, and to stimulate the biosynthesis of, the glycosaminoglycans and the hyaluronic acid backbone needed for the formation of proteoglycans found in the structural matrix of joints.
Chiropractic Use of Glucosamine Sulfate in the Treatment of Osteoarthritis
J Manip Physiol Ther 1997 (Jul-Aug); 20 (6): 400–414
The rationales for using NSAIDs in the treatment of osteoarthritis is controversial and openly contested. Given the detrimental effects of NSAIDs on joints and other organs, their use should be discouraged and their classification as a first choice conservative treatment should be abolished. (emphasis added) A truly effective and conservative approach to the treatment of osteoarthritis should include chiropractic manipulation, essential nutrient supplementation, exogenous administration of glucosamine sulfate and rehabilitative stretches and exercises to maintain joint function.
Longer–term Treatment of Mild–to–moderate Osteoarthritis of the Knee with Glucosamine Sulfate – A Randomized, Controlled, Double–Blind Clinical Study
European Jrnl of Clin Pharmacology 1996; 50 (6): 542
In conclusion, GS, is safe as but significantly more effective than placebo in controlling the OA symptoms over a 3-month treatment course and at least as effective as Pir, maintains its symptomatic-therapeutic benefit for at least 2 months while Pir loses its effect after withdrawal.
A Large, Randomized, Placebo Controlled, Double–Blind Study of
Glucosamine Sulfate vs Piroxicam and vs Their Association, on the Kinetics of the Symptomatic Effect in Knee Osteoarthritis
Osteoarthritis and Cartilage 1994; 2 (Sup 1) Dec
GS was confirmed an effective and well tolerated Symptomatic Slow Acting Drug in OA, with a steadily increasing effect, persisting after drug withdrawal. Pir was less tolerated, had a similar efficacy at the beginning of treatment, but that wore off at withdrawal.
Glucosamine Sulfate Compared to Ibuprofen in Osteoarthritis of the Knee
Osteoarthritis and Cartilage 1994: 2: 61–69
Glucosamine sulfate was therefore as effective as ibuprofen on symptoms of knee OA. These data confirm glucosamine sulfate as a safe symptomatic Slow Acting Drug for OA.
Efficacy and Safety of Intramuscular Glucosamine Sulfate in Osteoarthritis of the Knee: A Randomised, Placebo–controlled, Double–blind Study
Arzneimittel–Forschung 1994 (Jan); 44 (1): 75–80
Glucosamine sulfate (Dona, CAS 29031-19-4) is a drug used in the treatment of osteoarthritis. When orally given, it is more effective than placebo and at least as effective as non-steroidal anti-inflammatory drugs in relieving osteoarthritis symptoms. The aim of this multicentre, randomised, placebo-controlled, double-blind, parallel-group study was to assess the efficacy and safety of glucosamine sulfate intramuscularly given on the same parameters.
Antiarthritic Effects of Glucosamine Sulfate Studied in Animal Models
Arzneimittel–Forschung/Drug Research 1991 (May); 41 (5): 542–545
Since, however, the toxicity of indometacin in chronic toxicity experiments is 1000-4000 times larger, the therapeutic margin with regard to prolonged treatments of inflammatory disorders results 10-30 times more favourable for GS than for indometacin. GS can therefore be considered as a drug of choice for prolonged oral treatment of rheumatic disorders.
Reversal of Osteoarthritis by Nutritional Intervention
ACA Journal of Chiropractic November 1990 ~ FULL TEXT
Research from rheumatology and orthopedic clinics from Europe on the ability to reverse osteoarthritis has been accumulating for the last 25 years. Based on these results, this article will describe a nutritional program, that in conjunction with standard therapies used for osteoarthritis, can actually reverse the course of osteoarthritis.
Effect of Non–steroidal Anti–inflammatory Drugs on the Course of Osteoarthritis
Lancet 1989 (Sep 2); 2 (8662): 519–522
This paper explores the hypothesis that non–steroidal anti–inflammatory drugs (NSAIDs) accelerate the progression of osteoarthritis, by reducing synthesis of vasodilator prostaglandins, thereby diminishing joint perfusion of blood. They recommend that "potent inhibitors of prostaglandin synthesis may be inappropriate in the management of osteoarthritis of the hip" since that is the only joint they study. This paper explores the hypothesis that non–steroidal anti–inflammatory drugs (NSAIDs) accelerate the progression of osteoarthritis, by reducing synthesis of vasodilator prostaglandins, thereby diminishing joint perfusion of blood.
It is reasonable to extrapolate that this same inhibition takes place in all joint complexes.
Absorption, Distribution and Excretion of Radioactivity After a Single Intravenous or Oral Administration of [14C] Glucosamine to the Rat
Pharmatherapeutica 1984; 3 (8): 538–550
Blood levels, tissue distribution and excretion patterns of radioactivity were studied in the rat after administration of [14C] glucosamine sulphate by the intravenous or oral route. After intravenous administration, plasma radioactivity declined in the first 30 min, then increased, reaching a peak at the 2nd hour, and disappeared, with a half-disappearance time of 28 hours.
Oral Glucosamine Sulfate in the Management of Arthrosis: Report on a Multi–Centre Open Investigation in Portugal
Pharmatherapeutica 1982; 3 (3): 157–168
Oral glucosamine was fully tolerated by 86% of patients, a significantly larger proportion than that reported with other previous treatments and approached only by injectable glucosamine. The onset of possible side-effects was significantly related to pre-existing gastro-intestinal disorders and related treatments, and to concomitant diuretic treatment.
Double–blind Clinical Evaluation of Oral Glucosamine Sulphate in the Basic Treatment of Osteoarthrosis
Curr Med Res Opin 1980; 7 (2): 110–114
Significant alleviation of symptoms was associated with the use of the active drug at the prescribed dose. Similarly, patients given glucosamine sulphate experienced earlier alleviation of symptoms compared with those who had placebo. The use of glucosamine sulphate also resulted in a significantly larger proportion of patients who experienced lessening or disappearance of symptoms within the trial period.
Conservative Treatment of Spinal Arthroses with Glucosamine Sulfate and Phenylbutazone – A Controlled Study
Therapiewoche 1980; 30: 5922–5928
The use of several objectifiable parameters (Schober test, Lasegue test, distance from finger tips to floor when bending over) showed that combined oral and intramuscular administration of glucosamine sulfate for vertebral syndromes was as effective as a standard therapy with phenylbutazone. However, the average time of treatment required to achieve a clinically relevant result was signifcantly shorter. No side effects were observed.
Therapeutic Activity of Oral Glucosamine Sulfate in Osteoarthrosis: A Placebo-Controlled Double-Blind Investigation
Clinical Therapeutics 1980; 3 (4): 260–272
The patients who had placebo showed a typical picture of established osteoarthrosis. Those who had glucosamine sulfate showed a picture more similar to healthy cartilage. It is concluded that glucosamine sulfate tends to rebuild the damaged cartilage, thus restoring articular function in most chronic arthrosic patients.
Glucosamine Sulphate for the Management of Arthrosis: A Controlled Clinical Investigation
Curr Med Res Opin 1980; 7 (2): 104–109
During the maintenance period, a further significant improvement was recorded in the group receiving glucosamine, whereas with placebo the symptom scores rose to almost the pre-treatment levels. A similar pattern was shown in the measurement of walking speed. Clinical and biological tolerance were excellent with both treatments. No drug-related complaints were recorded, nor signs of interference in other illnesses or interactions with other drug treatments. It is suggested that injectable and/or oral treatment with pure glucosamine sulphate should be considered for the basic therapy of primary or secondary osteoarthrosis, mainly because it restores articular function to a certain extent.
