Osteoarthritis (OA) Specimens for Research

Bay Biosciences provides high-quality, matched fresh frozen sera (serum),  plasma, and peripheral blood mononuclear cells (PBMC) bio-fluids from patients diagnosed with osteoarthritis (OA).

Moreover, the sera (serum), plasma and PBMC bio-fluids are processed from osteoarthritis (OA) patient’s peripheral whole-blood using customized collection and processing protocols.

In addition, the matched bio-fluids are collected from unique patients with osteoarthritis (OA) and are provided to a valued pharmaceutical customer for research, development and drug discovery.

Osteoarthritis (OA) Overview

Osteoarthritis is the most common form of arthritis, affecting millions of people worldwide. It is among the most prevalent and disabling chronic conditions in the United States. The prevalence increases with age, and by the age of 65. Moreover, approximately 80 percent of the U.S. population is affected with osteoarthritis.

Osteoarthritis occurs when the smooth cushion between bones (cartilage) at the end of the bones breaks down over time. Moreover, joints can get painful, swollen and hard to move. Although osteoarthritis can damage any joint. This disorder most commonly affects joints in the hands, knees, hips, lower back, neck and the spine.

Furthermore, osteoarthritis can develop at any age, but it commonly starts in the 50’s. In addition, it affects women more than men. This disease starts gradually and worsens over time. 

Osteoarthritis (OA) Causes

In fact, osteoarthritis occurs when the cartilage that cushions the ends of bones in the joints gradually deteriorates. Moreover, cartilage is a firm, slippery tissue that enables nearly frictionless joint motion.

Eventually, if the cartilage wears down completely, bone will rub on bone.  OA can cause pain, stiffness, and swelling.

Osteoarthritis has often been referred to as a “wear and tear” disease. But besides the breakdown of cartilage, osteoarthritis affects the entire joint. Moreover, it causes changes in the bone and deterioration of the connective tissues. Which, hold the joint together and attach muscle to bone. It also causes inflammation of the joint lining. Osteoarthritis was believed to be caused by the wearing down of joints over time. In addition, researchers and scientists now see it as a disease of the joint. 

Factors

Following are some of the factors that may contribute to Osteoarthritis (OA): 

  • Age: The risk of developing Osteoarthritis increases with age as individuals gets older because bones, muscles and joints are also aging.
  • Joint Injury: A break or tear in the joints, can lead to Osteoarthritis after years. Injuries, such as those that occur when playing sports or from an accident, can increase the risk of osteoarthritis. Even injuries that occurred many years ago and seemingly healed can increase your risk of osteoarthritis.
  • Overuse, repeated stress on the Joints: If your job or a sport you play places repetitive stress on a joints, that joint might eventually develop osteoarthritis.
  • Obesity: Carrying extra body weight contributes to osteoarthritis in several ways, and the more you weigh, the greater the risk of developing Osteoarthritis. Increased weight adds stress to weight-bearing joints, such as your hips and knees. Extra weight also puts more stress on a joint and fats cells promote inflammation, fat tissue produces proteins that can cause harmful inflammation in and around the joints.
  • Weak Muscles: Joints can get out of the right position when there’s not enough support.
  • Genetics: Some people inherit a tendency to develop osteoarthritis, people with family members who have Osteoarthritis are more likely to develop Osteoarthritis.
  • Sex: Women are more likely to develop Osteoarthritis than men.
  • Bone Deformities: Some people are born with malformed joints or defective cartilage.
  • Certain metabolic diseases: These include diabetes and a condition in which your body has too much iron (hemochromatosis) can cause Osteoarthritis.

Osteoarthritis (OA) Signs & Symptoms

Osteoarthritis signs and symptoms often develop slowly and worsen over time, which include:

  • Pain and Aches: Pain or aching in the joint during of after movement or activity.
  • Stiffness: Joint stiffness usually occurs first thing in the morning or after resting.
  • Swelling around a joint: This might be caused by soft tissue inflammation around the joint.
  • Muscle Weakness: Osteoarthritis patients may feel muscle weakness around the joint.
  • Joint Instability: Joint instability or buckling  (knee gives out).
  • Tenderness: The joint might feel tender when light pressure is applied to or near it.
  • Loss of flexibility: Osteoarthritis patients might have a limited range of motion and not be able to move their joint through its full range of motion.
  • Grating Sensation: You might feel a grating sensation when you use the joint, and you might hear popping, clicking or crackling sound when a joint bends.
  • Bone Spurs: Extra bits of bone, which feel like hard lumps, can form around the affected joint.

Here are ways that Osteoarthritis (OA) may affect different parts of the body:

  • Hips: Pain is felt in the groin area or buttocks and sometimes on the inside of the knee or thigh.
  • Knees: A “grating” or “scraping” feeling when moving the knee.
  • Fingers: Bony growths (spurs) at the edge of joints can cause fingers to become swollen, tender and red. There may be pain at the base of the thumb.
  • Feet- The big toe feels painful and tender. Ankles or toes may swell.

As Osteoarthritis disease gets worse, cartilage may get uneven edges and cracks. Bones may harden, change shape and get bumpy. Once cartilage breaks down, it doesn’t grow back on its own.

Osteoarthritis (OA) Genetics

Osteoarthritis (OA) is a multifactorial disease which means that there are many different influences acting together to cause the appearance of the Osteoarthritis (OA) disease. Genetic factors have been found to be strong determinants of the Osteoarthritis (OA )disease. Evidence of a genetic influence of Osteoarthritis (OA) comes from a number of sources, including epidemiological studies of family history and family clustering and exploration of rare genetic disorders. Several studies have shown that the influence of genetic factors is between 39% and 65% in radiographic Osteoarthritis (OA) of the hand and knee in women, about 60% in Osteoarthritis (OA) of the hip, and about 70% in Osteoarthritis (OA) of the spine. Combined together, these estimates suggest a heritability of Osteoarthritis (OA) of 50% or more, indicating that half the variation in susceptibility to disease in the population is explained by genetic factors.

Studies have implicated linkages to Osteoarthritis (OA) on chromosome 2q, 9q, 11q, and 16p, among others. Genes implicated in association studies include VDR, AGC1, IGF-1, ER alpha, TGF beta, CRTM (cartilage matrix protein), CRTL (cartilage link protein), and collagen II, IX, and XI. Genes may operate differently in the two sexes, at different body sites, and on different disease features within body sites. Osteoarthritis (OA) is a complex disease, and understanding its complexity should help us find the genes and new pathways and drug targets.
