Prevalence of Osteoarthritis

Arthritis is considered the most common joint disorders in the world.

Osteoarthritis is by far the most common form of arthritis occurring in practice and is a leading cause for chronic disability in elderly patients

The annual prevalence of knee pain associated with OA is 46% in those over age 50.

In those with knee pain, around 1 in 5 patients indicate problems at work.

PGE2 has important pro-inflammatory properties and contributes to vasodilation and pain in patients with OA 2

Chondrocytes isolated from patients with OA produce 50-fold more PGE2 than chondrocytes from patients without OA

Arthritis Flare-Ups

Definition of Arthritis Flare Ups

Some forms of arthritis go through cycles of getting better and worse1

A flare-up means the disease is more active1

• Increased morning stiffness1

• More pain and swelling in the joints,1 (the pain becomes more severe and responds less to rest, tending to become continuous)2

• Involvement of other joint1

• Increased tiredness and fatigue1

Impact of Arthritis flare-ups & considerations Disability & sleep disorders are key symptoms associated with flare ups, proper management of flare-ups are crucial to avoid further damage

In patients with symptoms of OA flare-ups the following conditions are reported Significant work disability Reduced ability to deal with household duties Sleep disorders

It's important to address arthritic flare-ups as soon as possible, because of the damage ,the increased inflammation can do to already compromised joints

Diagnostic score for knee OA:KOFUS ( Knee Osteoarthritis Flare-Ups Score)

Diagnostic score for knee OAKOFUS ( Knee Osteoarthritis Flare-Ups Score)

Is to identify & validate a criteria for defining knee osteoarthritis flare-up, based on data from two large cross-sectional studies based on clinical features ,NO blood tests or joint fluid studies were performed

M. Marty et al. / Joint Bone Spine 76 (2009) 268e272

Objectives

Clinical features associated with a flare-up were Morning stiffness for longer than 20 min Nocturnal awakenings due to knee pain Limping Swelling Warmth Joint effusion

Diagnostic score for knee OA:KOFUS ( Knee Osteoarthritis Flare-Ups Score)Patients with a score of 7 & above are diagnosed as flare-ups patients

M. Marty et al. / Joint Bone Spine 76 (2009) 268e272

A score equal to or greater than 7 points indicates diagnosis of flare-up

Osteoarthritis Management

NSAIDs in Guidelines

To fully treat inflammation, a higher dose of NSAIDs must be taken on a regular basis for 2-4 weeks

Diclofenac in Arthritis Flare-Ups

• The recommended dose for arthritis flare-ups is, the full dose of Diclofenac which is 150 mg / day for 2 weeks.
