Therapeutic efficacy of undenatured type-II collagen (UC-II) in comparison to glucosamine and chondroitin in arthritic horses.

Abstract: The present investigation evaluated arthritic pain in horses receiving daily placebo, undenatured type II collagen (UC-II) at 320, 480, or 640 mg (providing 80, 120, and 160 mg active UC-II, respectively), and glucosamine and chondroitin (5.4 and 1.8 g, respectively, bid for the first month, and thereafter once daily) for 150 days. Horses were evaluated for overall pain, pain upon limb manipulation, physical examination, and liver and kidney functions. Evaluation of overall pain was based upon a consistent observation of all subjects during a walk and a trot in the same pattern on the same surface. Pain upon limb manipulation was conducted after the walk and trot. It consisted of placing the affected joint in severe flexion for a period of 60 sec. The limb was then placed to the ground and the animal trotted off. The response to the flexion test was then noted with the first couple of strides the animal took. Flexion test was consistent with determining clinically the degree of osteoarthritis in a joint. Horses receiving placebo showed no change in arthritic condition, while those receiving 320 or 480 or 640 mg UC-II exhibited significant reduction in arthritic pain (P < 0.05). UC-II at 480 or 640 mg dose provided equal effects, and therefore, 480 mg dose was considered optimal. With this dose, reduction in overall pain was from 5.7 +/- 0.42 (100%) to 0.7 +/- 0.42 (12%); and in pain upon limb manipulation from 2.35 +/- 0.37 (100%) to 0.52 +/- 0.18 (22%). Although glucosamine and chondroitin treated group showed significant (P < 0.05) reduction in pain compared with pretreated values, the efficacy was less compared with that observed with UC-II. In fact, UC-II at 480 or 640 mg dose was found to be more effective than glucosamine and chondroitin in arthritic horses. Clinical condition (body weight, body temperature, respiration rate, and pulse rate), and liver (bilirubin, GGT, and ALP) and kidney (BUN and creatinine) functions remained unchanged, suggesting that these supplements were well tolerated.

This article presents research showing that undenatured type II collagen, or UC-II, was more effective than glucosamine and chondroitin in reducing arthritic pain in horses, with dosages of 480 mg being optimal.

Study Overview

  • The research centered around evaluating the efficacy of undenatured type II collagen (UC-II). The researchers compared it to glucosamine and chondroitin, treatments traditionally used to mitigate the effects of arthritis in horses.
  • Horses were given daily doses of either a placebo, UC-II (at three different levels: 320 mg, 480 mg, and 640 mg), or a combined dose of glucosamine and chondroitin for 150 days.
  • The horses’ responses to these treatments were assessed through measurements of overall pain, pain upon limb manipulation, and via thorough physical examinations. In addition, liver and kidney functions were evaluated to assess tolerance and potential side-effects of the treatments.

Method of Evaluation

  • The horses’ overall pain levels were consistently evaluated during their walking and trotting routines. This took place on the same surface to maintain consistency in results.
  • A method called “pain upon limb manipulation” was also used. This involves placing the affected joint in a severely flexed position for 60 seconds, and then assessing the animal’s response when it starts to walk or trot again. This method is widely used to clinically determine the degree of osteoarthritis in a joint.

Results

  • It was found that 320 mg, 480 mg, or 640 mg doses of UC-II resulted in a significant reduction in arthritic pain amongst horses (P < 0.05), while the placebo group showed no statistical change in condition.
  • The 480 mg and 640 mg doses of UC-II were found to achieve relatively equal effects, so researchers designated the 480 mg dosage as the optimal one.
  • With the 480 mg dose, overall pain reduction was 88%, and pain upon limb manipulation was reduced by 78% in the horses.
  • Additionally, glucosamine and chondroitin treatments did result in a significant reduction in arthritic pain. However, the effectiveness of these treatments paled when compared to that of UC-II at doses of 480 mg or 640 mg.
  • Important factors such as body weight, body temperature, respiration rate, and pulse rate, as well as liver and kidney functions, remained constant, suggesting that the horses tolerated the supplements well.

Conclusion

  • The research concluded that UC-II is more effective than glucosamine and chondroitin at reducing arthritic pain in horses, making it a superior treatment option.
