Presentation of SLE (7)
Joint pain and stiffness Extreme tiredness Skin rashes (butterfly) Weight loss Swollen glands Sensitivity to light Raynaud's

- Malar rash
- Discoid rash
- Photosensitivity
- Oral ulcers
- Arthritis (>2)
- Serositis
- Proteinuria / cellular casts in urine
- Seizures or psychosis

what is the characteristic sign of scleroderma
Thickening and reddening of skin (morphea)
Types of scleroderma
- Localised - just affects skin (morphea or linear skin changes)
- Systemic - limited cutaneous systemic sclerosis and diffuse cutaneous systemic sclerosis
What is morphea
Discoloured oval patches on skin
Usually itchy
Can appear anywhere on body
Hairless and shiny
What is linear localised scleroderma
Thickened skin in lines along face, scalp, legs or arms
What is limited cutaneous systemic sclerosis
Milder form which only affects skin on the hands, lower arms, feet, lower legs and face - can eventually affect lungs and GIT
CREST Syndrome
What does CREST stand for
Calcium deposits Raynaud's Esophageal reflux Sclerodactyly Telangiectasia
What is diffuse cutaneous systemic sclerosis
Scleroderma more likely to affect internal organs, skin changes can affect whole body
Involves other symptoms which come on suddenly - weight loss, fatigue, joint pain and stiffness
Complications of limited scleroderma
Pulmonary HTN (small blood vessels in lungs become fibrosed)
Complications of diffuse scleroderma
Pulmonary fibrosis
Renal crisis
Small bowel bacterial overgrowth
What age group does scleroderma occur in
30-50
Peak onset of Sjögrens
40-50
Symptoms of Sjögrens
Dry mouth and lacrimal glands Fatigue Fever Myalgia Arthralgia
Complications of Sjögrens
Lymphoma Neuropathy Purpura Interstitial lung disease Renal tubular acidosis
