Connective Tissue Disorders Flashcards
Sjogrens
Autoimmune condition characterised by lymphocytic infiltrates in exocrine organs.
Sjogrens Symptoms
Dry mouth, eyes and vagina. Poor dental health. Myalgia and Arthralgia. Raynauds Parotid gland swelling
Sjogrens associated conditions
Peripheral neuropathy and interstitial lung disease
Increased risk of lymphoma
Immunology in Sjogrens
Anti Ro and Anti La
Raised IgG and plasma viscosity.
Diagnosis of Sjogrens
Ocular dryness
+ve anti-Ro and anti-LA antibodies
Lip gland biopsy
What test is used to determine ocular dryness?
Schirmers test
Sjogrens treatment
Largely symptomatic e.g lubricating eye drops etc
Regular dental care
If the patient with Sjogrens has arthralgia what can be used?
Hydroxychloroquine
Systemic sclerosis
Multisystemic autoimmune disease characterised by vasculopathy autoimmunity + fibrosis.
Systemic sclerosis
Cutaneous Presentation
Raynauds Skin becomes thickened and tight leading to Beaking of the nose, Atrophy of the fingertips Telangiectasia Calcinosis Sclerodactyly
Systemic sclerosis
GI Presentation
Dysphagia, malabsorption, fluctuating diarrhoea/constipation, faecal incontinence
Systemic sclerosis
Pulmonary presentation
Pulmonary hypertension
Pulmonary fibrosis
Systemic sclerosis
Renal Presentation
Accelerated hypertension
Proteinuria
Worsening renal function
How can systemic sclerosis be divided?
Limited- Skin involvement in hand feet and face.
- Linked to anti centromere
- Organ involvement is later
Diffuse- skin involvement includes trunk.
- linked to Anti Scl-70 antibody
- early significant organ involvement.
Systemic Sclerosis treatment
No overall treatment instead tailor to specific systemic involvement.
Systemic sclerosis treatment - Raynauds
Primary Raynauds - Calcium Channel Blockers
- ARB’s Nitrates
Recurrent Digital Ulcers - PDE- 5 Inhibitor Sildenafil
- Bosentan endothelia receptor agonist.
Systemic Sclerosis treatment - Pulmonary hypertension
PDE 5 inhibitor Sildenafil
Bosentan
oOxygen
Systemic Sclerosis treatment - Pulmonary Fibrosis
Mycophenolate Mofetil
Cyclophosphamide ( for aggressive fibrosis)
Rituximab
Nintedanib (anti-fibrotic)
Systemic sclerosis renal presentation and treatment
Associated with Anti RNA polymerase III antibody
Uncontrolled hypertension and renal failure.
ACE or ARB +/- dialysis
