Study Overview
Brief Summary
Osteoarthritis (OA) is the most common kind of arthritis and primarily affects the large, weight bearing joints (including the knees, lower back, hips, neck and the feet) and the joints in the hands. OA results from the breakdown of cartilage in joints, leading to joint pain and damage. It affects about 8 million people in the United Kingdom and nearly 27 million people in the United States, most of whom are over the age of 45.
This study aim to determine if Aquamin (as AquaCal and AquaPT) affects molecules of inflammation in the blood of osteoarthritis and healthy subjects.
Detailed Description
Aquamin is a seaweed-derived mineral source, which is rich in calcium, magnesium and 74 other trace minerals including zinc, iron and selenium. It is produced from the red algae, Lithothamnion Calcareum, which is found in just three locations in the world, including the south-west coast of Ireland and Iceland. During a five-year life span, these algae absorb essential minerals from the sea - this gives Aquamin its unique multimineral content. The algae then break down naturally and settle on the sea bed. These calcified skeletal remains are harvested, washed, dried and milled and provided in a capsule formulation. AquaCal is the capsule form of Aquamin. AquaPT contains green tea and pine bark extract.
Osteoarthritis (OA) is the most common kind of arthritis. OA is called degenerative arthritis, is a disease that results from the breakdown of cartilage in joints, leading to joint pain and damage. OA is very variable and there are lots of different types affecting different joints. This degenerative disease primarily affects the large, weight bearing joints (including the knees, lower back, hips, neck and the feet) and the joints in the hands. In OA, the disease begins with the degeneration of the cushion of cartilage between the joints. As it degrades, the synovium and the ends of the bones thicken, resulting in the pain and stiffness associated with arthritis. The progressive cartilage deterioration is followed by "hardening of the joints" due to calcification and bone spur formation. Treatment generally involves a combination of exercise, lifestyle modification and analgesics. If pain becomes debilitating joint replacement surgery may be used to improve the quality of life.
Symptoms of Osteoarthritis include early morning joint stiffness and pain, loss or restriction of joint mobility, pain that is worse after use, stiffness after periods of rest, creaking/cracking of joints after movement (also known as crepitus), tenderness and swelling in certain areas, restricted mobility, pain in the joint before or during changes in the weather and deformity of the joints.
Osteoarthritis is the leading cause of chronic disability in the United States.[1] It affects about 8 million people in the United Kingdom and nearly 27 million people in the United States, most of whom are over the age of 45. A number of studies have shown that there is a greater prevalence of the disease between siblings and especially identical twins, indicating a hereditary basis [2]. Up to 60% of OA cases are thought to result from genetic factors. Other factors causing OA are congenital disorders of joints, diabetes, inflammatory diseases and all chronic forms of arthritis. In addition, injury to joints as a result of an accident, septic arthritis, Marfan syndrome, obesity, ligamentous deterioration or instability may also be factors.
Current anti-inflammatory treatments for OA while providing some relief from symptoms are suboptimal and the side effects associated with these treatments; in particular the COX-2 specific NSAID's are becoming increasingly recognized [3,4]. As a result of this, use of alternative treatments and complementary medicines are gaining popularity among OA sufferers.
