23
Q

What is psoriatic arthritis?

A

A chronic inflammatory joint disease which develops in patients with psoriasis

24
Q

What group of conditions does psoriatic arthritis fit into?

A

Seronegative spondyloarthropathies

25
Q

What are the 5 types of psoriatic arthritis?

A
  1. Symmetrical seronegative polyarthritis
  2. Asymmetrical oligoarthritis
  3. Sacroilitis
  4. DIP joint disease
  5. Arthritis mutilans
26
Q

What is the most common form of psoriatic arthritis and what does it resemble?

A

Symmetrical seronegative and its like rheumatoid arthritis

27
Q

What signs are seen in DIP joint disease?

A
  • DIP joint involvement only

  • Dactylitis
28
Q

What signs are seen in arthritis mutilans?

A
  • Telescoping fingers

29
Q

Does all psoriatic arthritis present with psoriasis?

A

No, can present with or without skin changes

30
Q

How does the psoriatic plaque form in psoriatic arthritis?

A

Inflammation leads to cytokine production which leads to proliferation of keratinocytes and fibroblasts leading to formation of the psoriatic plaque

31
Q

How do the bone deformities in psoriatic arthritis form?

A

T cells activate OB and OC in joint spaces

32
Q

Where does psoriasis mainly occur?

A

Over extensor surfaces

33
Q

What is the presentation of psoriatic arthritis?

A
  • Inflammatory pain - red, warm, painful, stiffness and swelling
  • Psoriatic Arthritis Mutilans - marked bony resorption and the consequent collapse of soft tissue, can cause a phenomenon sometimes referred to as “telescoping fingers”.
  • Associated nail changes in 80% - Nail pitting and
  • Onycholysis
  • Psoriatic rash
  • Dactylitis
34
Q

What investigations would you do in psoriatic arthritis?

A
  • Bloods

- X-ray

35
Q

What would you see on the blood test in psoriatic arthritis?

A

RF negative and ESR often normal

36
Q

What would you see on the X-ray in psoriatic arthritis?

A
  • DIPs are predominantly affected
  • Central erosions
  • Pencil in cup changes
37
Q

What are the 4 treatment options for psoriatic arthritis?

A
  1. NSAIDs
  2. DMARDs
  3. INtra articular steroid injections
  4. Anti-TNF
38

Q

What are the three main GI infection causes for reactive arthritis?

A
