Managing Arthritis Flare-Ups
Prof.Hisham Hamoud
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.

Pathophysiology
50 folds more PGE2 in osteoarthritis patients’ chondrocytes
 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
worse
1
 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

Objectives

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
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
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
http://www.uptodate.com
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.
