A

Butterfly rash, photosensitivity, dry mouth, raynauds phenomenon, nephritis, pleural effusion, protein and hematuria

30
Q

What is lupus

A

Autoimmune multisystem connective tissue disease characterised by auto antibodies attacking cell nuclei. ANA then form antigen-antibody complexes that travel around the body depositing in vessels and organs leading to type 3 hypersensitivity reaction

31
Q

What is management of lupus ?

A

Focus on preventing flares and reducing their severity
Lifestyle advice to avoid sunlight and other triggers
Limit severity with corticosteroids and immunosuppressants

32
Q

What is sjögren’s syndrome?

A

Autoimmune connective tissue disease that is rheumatoid factor positive. Dry mouth and eyes most common

33
Q

What is systemic sclerosis?

A

Unknown aetiology, hardened, sclerotic skin. Can be limited, diffuse or without internal organ involvrment

34
Q

What are the types of arthritis?

A

Inflammatory, non inflammatory (osteoarthritis), septic, crystal (gout/pseudogout)

35
Q

Early morning stiffness of >30 minutes suggests what?

A

Inflammatory arthritis

36
Q

What does a ‘boggy’ swelling of the joint indicate?

A

Suggestive of synovitis which occurs in inflammatory arthritis

37
Q

What joints does rheumatoid arthritis normally effect?

A

Wrists, metacarpal phalanges, and proximal interphalangeal joint (not distal). Involve the is usually symmetrical

38
Q

Describe swan neck deformities and in what condition they are found

A

Hyper extension of proximal interphalangeal joint and flexion of the distal interphalangeal joint. Rheumatoid arthritis

39
Q

Describe Boutonniere deformity and what condition causes it

A

Flexion of the proximal interphalangeal joint and hyperextension of the distal interphalangeal joint. Rheumatoid arthritis

40
Q

Define guttering

A

Muscle wasting seen over the dorsum of the hand

41
Q

If you’re a GP and you think someone has rheumatoid arthritis what do you do?

A

Prescribe analgesia for symptomatic relief and refer urgently to rheumatology. Rapid treatment improves long term outcomes, by maintaining function and quality of life

42
Q

What blood tests would you complete to confirm rheumatoid diagnosis?

A

Rheumatoid factor and anti-CCP antibody. Antinuclear antibody may ) di Cate connective tissue disease
Baseline blood tests (FBC, U&E, LFTs), TFTs, plain radiographs of the hands and feet

43
Q

How is rheumatoid arthritis diagnosed

A

By a rheumatologist and according to ACR classification criteria
Basically duration, number and type of joints involved, antibody tests and CRP and ESR

44
Q

How’s is disease activity in rheumatoid arthritis monitored?

A

Using the disease activity score - DAS28

45
Q

What is the treatment for active rheumatoid arthritis?

A

Combination of DMARDs (disease monitoring anti-rheumatic drug), normally methotrexate and hydroxychloroquine, AND with a corticosteroid

46
Q

Names some DMARDs

A

Methotrexate and hydroxychloroquine are the most common

Others include leflunomide and sulphasalazine

47
Q

What are some of the known complication of rheumatoid arthritis?

A

Carpal tunnel syndrome, haemolytic anaemia

Felty’s syndrome (combination of RA, splenomegaly and neutropenia)

48
Q

What is the onset for psoriatic arthritis?

A

Mono arthritis that gradually gets worse

49
Q

What are the crystals found in gout?

A

Monosodium urate that are needle shaped and strongly negatively birefringent- yellow under polarized light

50
Q

Describe the crystals found in pseudo gout I

A

CPPD crystals positively birefringent rhomboid crystals - blue under polarized light

51
Q

What tests do you need to do if you suspect gout?

A

FBC, U&E, LFTs, CRP AND ESR (helps monitor response to treatment esp in septic arthritis), serum urate (low/normal does not rule out gout). Joint aspiration and synovial fluid analysis microscopy-GOLD STANDARD!

52
Q

Is warfarin a contraindication for joint aspiration?

A

No

53
Q

How is an acute attack of gout treated?

A

Naproxen - but not in renal impairment, and may need gastroprotectors
Colchicine, start asap when NSAIDs don’t work. Start at low dose to avoid diarrhoea
Prednisolone intra-articular v effective if not responding to other treatment - but not in diabetics!

54
Q

What are the conditions necessary to begin patient on prophylactic treatment for gout?

A
Established diagnosis of gout AND one of:
Two or more gout attacks per year
Tophus by clinical imaging study
CKD Stage 2 or worse
Urolithiasis
55
Q

What is the aim of prophylactic gout therapy?

A

To maintain a lower serum uric acid (sUA)<300 micromoles/L

Lower the sUA greater chance of dissolution of tophi

56
Q

When should urate lowering therapy be introduced following. An acute attack of gout?

A

2-4 weeks after attack has subsided

57
Q

What is the prophylactic treatment for gout?

A
