Emphysema
how does interstitial lung disease present?
Progressive SOB on exertion
Dry cough
Malaise, fatigue
Weight loss
What might you see on examination of a patient with interstitial lung disease?
Clubbing
Scars
Reduced chest expansion
Fine late end-inspiratory crepitations that do not clear with coughing but do quieten/disappear on leaning forwards
What are the underlying causes of interstitial lung disease (and their signs)
Rheumatoid arthritis: peripheral symmetrical deforming polyarthropathy (swan neck deformity, Z thumb, ulnar deviation at wrist, may have nodules) NB: the cause of the pulmonary fibrosis may be RA itself or methotrexate use in an RA patient
Amiodarone: slate grey appearance, pacemaker, may be in AF, photosensitivity
Connective tissue disease: cutaneous signs of systemic sclerosis, lupus, dermatomyositis
Ankylosing spondylitis: question mark posture, protuberant abdomen
Radiation: may have radiation tattoo on chest wall, lymphadenopathy
Sarcoidosis: cutaneous signs of sarcoidosis
What causes upper zone fibrosis
BREAST
Berylliosis
Radiation e.g. for breast cancer
Extringic allergic alveolitis, pneumoconiosis e.g. coal workers
Ankylosing spondylitis, ABPA (Allergic bronchopulmonary aspergillosis)
Silicosis, sarcoidosis psoriasis
Tuberculosis (and histoplasmosis and histiocytosis-X)
What causes lower lobe fibrosis?
RASIO
Rheumatoid arthritis
Asbestosis
Scleroderma, SLE, Sjogrens (and poly/dermatomyositis)
Idiopathic pulmonary fibrosis
Others: Drugs- methotrexate, bleomycin, busulphan, cyclophosphamide, nitrofurantoin, isoniazid, amiodarone, phenytoin, carbamazepine, gold, sulphasalasine.
How would you investigate lung fibrosis?
Bedside: ECG, ABG
Bloods: FBC (eosinophilia, anaemia, polycythaemia), CRP, ESR, Autoimmune screen including antibodies, serum ACE
Imaging: CXR, High resolution CT
Special tests: Lung function tests, Biopsy, Echo (Pulmonary HTN)
What signs might you see on CXR of someone with pulmonary fibrosis?
Bilateral reticulonodular interstitial infiltrates (parenchymal shadowing)
Ground-glass/honeycombing if advanced
Volume loss
Which signs might you see on HRCT of a patient with pulmonary fibrosis?
Reticulation
Ground glass (usually good response to steroid treatment)
Volume loss
Honeycombing
How would you manage Pulmonary Fibrosis?
Conservative: Stop smoking, remove triggers, vaccines, pulmonary physio
Medical: Treat cause. Manage infections. Steroids. Immunosuppressants (Azathioprine)
Surgical: Lung Transplant
How would bronchiectasis present?
Shortness of breath
Chronic productive cough: thick, smelly, purulent sputum
Haemoptysis
Recurrent infections
Pleuritic chest pain
Weight loss
History of childhood infections, sinusitis, subfertility
Which signs might you see in a patient with bronchiectasis?
Clubbing
May have scars
Reduced chest expansion
Early coarse inspiratory crepitations that alter with coughing but do not quieten/disappear on leaning forwards
Wheeze, inspiratory clicks
Which complications of bronchiectasis might you be able to pick up on on examination?
respiratory failure (oxygen, cyanosis, CO2 retention flap)
cor pulmonale (RV heave, loud P2, raised JVP, peripheral oedema)
infection (bronchial breathing, antibiotics at bedside, fever)
What might cause bronchiectasis?
Cystic Fibrosis: young, thin, short, PEG, portacath/Hickmann, signs of chronic liver disease
Kartagener’s Syndrome: Dextrocardia
Connective tissue disease: peripheral symmetrical deforming polyarthropathy, cutaneous signs of lupus
Yellow Nail Syndrome: yellow nails, lymphoedema
COPD, HIV, Post-infective (TB, pertussis, measles)
How might you investigate bronchiectasis?
Bedside: ABG (Resp Failure), ECG (R.Heart Strain)
Bloods: FBC (anaemia, eosinophilia), CRP, Autoimmune screen, HIV test, Aspergiluus percipitins and IgE
Sputum MC&S
Imaging: CXR, HRCT
Lung Function tests, Biopsy, Sweat test
What might you see on CXR of a patient with bronchiectasis?
Tramlines (diseased bronchi side on)
Ring shadows (diseased bronchi end on)
Gloved finger: mucoid impactions in large air ways
Hyperinflation
7% normal CXR
What might you see on HRCT of a patient with bronchiectasis?
Signet ring sign- thickened end-on dilated bronchus >1.5 times larger than adjacent pulmonary artery
Tram tracking
Ring shadows
Volume loss
Flame and blob sign: mucus plugging
How would you manage bronchiectasis?
Conservative: Stop smoking, vaccines, physiotherapy
Medical: Treat cause, steroids, bronchodilators, ABx
Surgical: Lobectomy, Transplant
What are the main complications of bronchiectasis?
infection (Pseudomonas, Haemophilus influenzae), Empyema, Cor Pulmonale, Anaemia, Secondary amyloidosis
