  3. Late AS: loss of lumbar kyphosis with pronounced cervical lordosis
32
Q

What is Schober’s Test used for in AS?

A

Schober’s test measures lumbar spine flexion.

= A normal result should show an increase of more than 5 cm in the measured distance when the patient bends forward

Q

What is the hallmark X-ray finding in Ankylosing Spondylitis?

A

Bamboo spine

34
Q

What is the first-line pharmacological treatment for Ankylosing Spondylitis?

A

NSAIDS

35
Q

What are the ASAS classification criteria for diagnosing axial spondyloarthritis?

A

Criteria require ≥3 months of back pain and onset before age 45

+ either sacroiliitis on imaging and

(1) ≥1 SpA feature
(2) HLA-B27 positivity and ≥2 SpA features

36
Q

What are the surgical options in Ankylosing Spondylitis?

A

Mainly for hip and knee arthritis and is reserved for severe cases.

Kyphoplasty for spinal issues is controversial and carries significant risk.

37
Q

What is Enteropathic Arthritis?

A

IBD associated arthritis -

Inflammatory arthritis, involving the peripheral joints and sometimes the spine, occurs in patients with inflammatory bowel disease

38
Q

What gastrointestinal symptoms are common in IBD-associated arthritis?

A

Loose, watery stool with mucus and blood

weight loss

39
Q

What is the diagnostic finding in joint aspiration for IBD-associated arthritis?

A

No organisms or crystals

40
Q

What imaging modalities are used to diagnose sacroiliitis in IBD-associated arthritis?

A

X-ray or MRI

41
Q

What treatment leads to improvement in enteropathic arthritis?

A

Treating the underlying inflammatory bowel disease (IBD)

42
Q

A 21-year-old female presents to the rheumatology clinic with a 6-week history of joint pain, swelling and early morning stiffness affecting her left ankle and right knee. The pain is improved with movement. On further questioning, over the past few years, she has also been experiencing recurrent episodes of crampy central abdominal pain and diarrhoea, sometimes with blood in the stool and this has been especially bad during the last few weeks too.

What is the most likely cause of her joint pain?

A

Enteropathic arthritis

43
Q

Signs and symptoms of Enteropathic arthritis are what?

A

(1) Lower back pain

(2) Stiffness

(3) Localised pain in specific tendon insertion areas

(4) Transient joint inflammation

44
Q

Seronegative spondyloarthropathies should all be what?

A

RF and ANA negative

p-ANCA is seen in 55–70% of patients with ulcerative colitis

45
Q

When should coxibs be considered in place of NSAIDs?

A

When NSAIDs are needed, but there is a high risk of GI ulceration

46
Q

Enteropathic arthritis is a feature of which GI diseases?

A

Inflammatory bowel disease (either Crohn’s or UC)

47
Q

What are the differences between the clinical features of inflammatory and mechanical joint pain?

A

Inflammatory:
- Improves movement.
- Prolonged (>30 min) early morning stiffness.

Mechanical:
- Exacerbated by movement.
- Short early morning stiffness (<30 min).

48
Q

Which features would you expect to see on lumbar XR in a patient with ankylosing spondylitis?

A
  1. Squaring of the vertebrae
  2. Syndesmophytes
  3. A bamboo sign (late)
49
Q

What is reactive arthritis?

A

An infection-induced systemic illness characterised by inflammatory synovitis, where microorganisms cannot be cultured.

50
Q

What are the most common preceding infections for reactive arthritis?

A

Urogenital infections (e.g., chlamydia, Neisseria)

Entheogenic infections (e.g., salmonella, campylobacter)

51

What gene is associated with reactive arthritis?

A

HLA B27

52
Q

What age group is most commonly affected by reactive arthritis?

A

Young adults, aged 20-40

53
Q

What are the main triggers of reactive arthritis?

A

Sexually transmitted infections (STI) or gastroenteritis

54
Q

When do symptoms of reactive arthritis typically appear?

A

1-4 weeks after the initial infection

55
Q

What type of arthritis is most common in reactive arthritis?

A

Asymmetrical monoarthritis or oligoarthritis

Q

What is Reiter’s syndrome?

A

A triad of urethritis, conjunctivitis/uveitis/iritis, and arthritis

57
Q

What investigations are used to diagnose reactive arthritis?

A

Increased inflammatory markers
Blood cultures
Urine/stool cultures
Joint fluid analysis
X-ray
Ophthalmology opinion

58
Q

What is the typical outcome of reactive arthritis?

A

Most cases are self-limiting, with 90% resolving spontaneously within 6 months

59
Q

What is the management for reactive arthritis?

A

Symptomatic relief → (IA/IM steroid injections)

Chronic cases → DMARDs may be needed

60
Q

A

M: F 9:1

(Compared to 3:1 for ankylosing spondylitis and 1:9 for SLE)

61
Q

What is the most common route of infection in Septic Arthritis?

A

The most common is haematological which means that the source of infection is coming from somewhere else in the body

62
Q

What is the management of patients with ankylosing spondylitis who have ongoing back pain despite using NSAIDs and following a regular exercise routine?

A

TNF-a inhibitors such as Infliximab

63
Q

Why is a joint aspiration done in a suspected diagnosis of Septic Arthritis?

A

Joint aspiration is done for two reasons;

(1) to remove all the infected fluid and to send the fluid for urgent Gram stain

(2) culture to determine the sensitivities and confirm the diagnosis

64
