Fibromyalgia

Nicolas Milhavy

GP ST1 VTS

16

Not well understood despite widespread research in the USA,

Canada and Europe……

Can have a definite trigger or can come on gradually out of the blue

17

Diagnosis

• A history of chronic and widespread pain (CWP)

• ‘Pain and fatiguability with multiple hyperalgesic tender sites

(11/18)’

18

American College of

Rheumatology – Classification

(1990)

1.

Pain in the left and right side of the body, pain above and below the waist and axial skeletal pain (shoulder and buttock included on each side and lower back pain considered lower segment pain) for at least 3 months

19

American College of

Rheumatology – Classification

2. Pain (not tenderness) with digital palpation in 11/18 sites

(1990)

» Occiput – bilaterally

» Low cervical C5-C7

» Trapezius – bilateral

» Supraspinatous – above scapula

» Second rib – bilateral

» Lateral epicondyle – bilateral

» Gluteal – bilateral

» Greater trochanter – bilateral

» Knee - bilateral

20

‘Manchester’ Definition

Pain must be present in 2 separate sections of a body quadrant to be positive

21

Epidemiology

• CWP prevalence is above 10% if American College of Rheumatology definition is used

• CWP prevalence is 5% with ‘Manchester’ definition

• Twice as high in females

• Fibromyalgia

» 0.7-4.8% in comparable studies using ACR criteria

» 90% female, peaks aged 40-50

22

Clinical picture

• Pain – axial and diffuse, felt all over

• Pain worsened by stress, cold and activity, association with

EM stiffness

• Parasthesiae in hands and feet common

• Analgesics and NSAIDs ineffective and may worsen symptoms

• Poor sleep pattern – wake exhausted and poor concentration

• Anxiety and depression scores are high

• Unexplained headaches, urinary frequency and abdominal symptoms are common

• Clinical findings unremarkable

23

Pathogenesis

• A poor, unrefreshing sleep pattern – unable to enter the 4 th phase of sleep (deep refreshing sleep)

• Muscles do not relax and resting muscle tension is raised – this causes aching all over that means the person cannot sleep well the following night – a vicious circle that is difficult to get out of

• Napping in the day worsens symptoms as it means the body cannot enter the restorative phase

• Low levels of NTs in the brain and abnormal processing of sensory stimuli – light touch and movements can cause significant pain that is real with no structural explanation

• Reduced aerobic fitness

• Behavioural affective symptoms

24

• Hypothyroidism

• SLE

• Sjorgren’s

• Psoriatic arthritis

• Inflammatory myopathy

• Hyperparathyroidism

• Osteomalacia

Differential Diagnosis

25

Diagnosis

• Exclude differential

• FBC, ESR, TFTs, U and Es, Calcium, CK, phosphate, ANA, RhF and immunoglobulins

26

Management

• Good explanation

» To patient and the family

» Relieve concerns of sinister causes for pain

» Rationalise with lack of sleep and fitness

• Avoid unnecessary investigation

• Regulate a better and more refreshing sleep pattern

• Increase aerobic exercise or physiotherapy (a graded and sustainable exercise regime)

• Low dose amitriptylline, dothiepin or fluoxetine

• Consider CBT or counselling

• MDT approach with rheumatology and pain clinic

27

• Poor

• 20% are symptom free at 5 years

• Treatment may help with coping strategies

• De Qervain’s tenosynovitis not responding to rest and a wrist support

• Early morning stiffness and pain in shoulders with raised ESR

• Acutely swollen first MTP joint

• Acute onset lumbar backakce when lifting with right sided sciatica

• Pt with fibromyalgia complains of multiple tender points in her shoulders; examination reveals normal range of movement but numerous trigger points within the muscles.

79

Case

• 42 year old male police officer

• Acutely swollen, hot right knee

• Feels tight, limping slightly

• No history injury

• PMH: prev ACL repair, previous patellar dislocation, high cholesterol, gout (toe and thumb – once a year for 8 years)

• SH: drinks 15 pints per week.

80

Examination

• Moderate effusion to knee

• Warm to touch

• No erythema

• Ligaments stable

• Recent exacerbation gout in right thumb – improved with indometacin. Been taking last 3d for knee – no improvement.

81

Differentials

• Infection

– cellulitis

– septic bursitis

– aseptic arthritis

• Rheumatoid arthritis

– polyarticular gout that affects the fingers may be mistaken for rheumatoid arthritis

– if there are elbow tophi these may be mistaken for rheumatoid nodules

• Bunion

• Chondrocalcinosis - pseudogout

• Seronegative arthritis

82

Investigations

• Serum urate (optimal time 2w after attack)

• Leucocytosis and raised ESR/CRP during attack

• Assess other CV risk factors – fasting lipid, BP, glucose

• Aspiration and polarised light microscopy of synovial fluid

• Radiology

83

• Correct exacerbating factors

– Consider stopping or reducing diuretics

– Reconsider aspirin

– Reduce alcohol intake

– Reduce intake of purine rich foods

• NSAIDs –

– 1 st line = indometacin, diclofenac, naproxen

– Azapropazone

– Etoricoxib 120mg daily

Treatment

84

Treatment alternatives

• Colchicine

– in patients with peptic ulcer disease / heart failure / CIs to NSAIDs /

HTN

– can be combined with anticoagulation

– does not cause fluid retention

– Dose is 1 mg, then 500 mcg every 2-3 hours until the pain resolves, or the patient develops diarrhoea, or a total dose of 6mg has been taken. Treatment with colchicine should not be repeated within 3 days.

– Common side effects are diarrhoea and gastric irritation.

• Steroids – tapering oral dose / IM injection / intra-articular

(large joint)

85

If not subsiding in 12-24h, reconsider diagnosis

86

Gout

• Disorder of purine metabolism

• Characterized by acute, recurrent attacks of synovitis due to urate crystal deposition

• Leads to cartilage degeneration

• Most common in men (20:1) and in post-menopausal women

87

• Primary (95%) – inherited discorder that causes overproduction/underexcretion. Underlying biochem defect unknown

• Secondary

– Increased formation uric acid

– Reduced excretion

– Drugs/toxins

– Misc

88

The great toe demonstrates extensive juxta-articular erosions with soft tissue swelling and little osteoporosis

89

Chronic gout

• Frequent recurrence of acute attacks of gout, the presence of tophi, or signs of chronic gouty arthritis may call for the initiation of longterm (‘interval’) treatment

• 2 choices:

– xanthine-oxidase inhibitors

– uricosuric drug – sulfinpyrazone, probenecid, benzbromarone

90

Allopurinol

• Xanthane oxidase inhibitor

• Reduces synthesis of uric acid

• Can precipitate an attack - give NSAID/colchicine concomitantly for first 3 months

• Do not commence during acute attack – can prolong. Start 1-2 weeks later.

• Can cause rashes

91

Febuxostat

• Licensed for the treatment of chronic hyperuricaemia where urate deposition has already occurred

• 80mg once daily

• for patients who are intolerant of allopurinol or for whom allopurinol is contra-indicated

Raynauds

Pathogenesis : Exaggerated vasoconstriction of arteries and arterioles [usually hand and feet]

• Causes : Mostly idiopathic, cold, emotions

97

• Symptoms:-

– Pain within the affected extremities

– Discolouration [white, blue, red]

– Sensation of cold and numbness

• Prevalence

– More common in women than men

Raynauds cont.

98

Primary Raynauds

• Primary Raynauds disease:-

– Reflects exaggeration of central and local vasomotor responses to cold or emotional stresses.

– Course of Raynauds is usually benign, however when long-standing can result in:-

• Atrophy of the skin, subcutaneous tissue and muscles

• Ulceration and ischaemic gangrene [rare]

99

Secondary Raynauds

• Secondary Raynauds

– Refers to a vascular insufficiency of the extremitites secondary to arterial disease:-

• Connective tissue disorders: SLE, sceleroderma [Specificsystemic sclerosis- CREST]

• Obstructive disorders: Atherosclerosis, Buerger disease

• Drugs: b-blockers, sulfasalazine

• Occupation: jobs involving vibration

• Raynauds may be the first manifestation of such conditions so be ready to consider.

100

Treatment

• General care:-

– Avoid triggers e.g. cold, vibration, emotional stress

– Keep hands and feet warm- mittens, insulated foot wear.

– Quit smoking

– Avoid caffeine

• Drug therapy

– Medicines that dilate blood vessels

– Calcium channel antagonists [Nifedipine or diltizem] – headache, flushing, ankle oedema

– Fluoxetine [SSRI] reduce frequency if associated with emotional trigger.

• Surgical – may require sympathectomy; botox

101

• The most common cause of Raynaud's Phenomenon is?

A. Idiopathic

B. Rheumatoid arthritis

103

Case 2

• A 45yr old woman presents with bilateral painful and deformed

DIP joints. She also states that over the past few weeks that her eyes appear red. Further examination reveals discolourisation and onycholysis of the nails.

104

Psoriatic arthritis

• Is a type of inflammatory arthritis

• Affects around 10-30% of people suffering from the skin condition psoriasis

• Seronegative spondyloarthropathy

• App 80% of patients with psoriatic arthritis will have psoriatic nail lesions

• Can occur at any age

• Occurs app 10yrs after the first signs of psoriasis

• Men and women equally affected

105

Psoriatic arthritis cont.

• Presentation:-

– Causes joint, ligament inflammation

106

Types of psoriatic arthritis

• Asymmetric : 70% of cases.

• Symmetric : 25% of cases. Affects joints on the same side of the body simultaneously.

• Arthritis mutilans : <5% of cases. Severe deforming and destructive artritis

• Spondylitis : Characterised by stiffness of the neck or spine.

• DIP predominant : 5% of cases. Inflammation and stiffness in the DIP joints.

107

Treatment

• Underlying process of psoriatic arthritis is inflammation  control inflammation

– First line: NSAIDs [ibuprofen, diclofenac]

– Joint injections [corticosteroids]

– Second line: If NSAID and/or steroids not working need immunosupressants:-

• Methotrexate, Leflunomide

Adv: immunosupressant treatment [covers arthropathy and psoriasis].

Severe cases: a-TNF agents e.g. inflixamab [reserved for the most severe cases.

108

• Psoriatic arthropathy is associated with which ONE of the following features:-

• A. A preceding history of skin lesion in the majority of patients

• B. Non involvement of the DIP joints

• C. Subcutaneous nodules

• D. Gallstone in the majority of patients

• E. The development of some evidence of joint involvement in the majority of patients with psoriasis

109

• In psoriatic arthropathy:-

• A. HLA B27 is associated with spondylitis.

• B. Arthritis mutilans is the most common pattern

• C. Onychopathy (nail pitting, ridging or onycholysis) is frequently associated with disease of the adjacent DIP joint.

• D. The severity and extent of synovitis is proportional to the extent of the psoriasis.

• E. Sulfasalazine might improve both psoriasis and arthritis.
