  10. Aberdeen & Norwich Surrounded by castles

  11. Differential diagnosis of Obstructive Lung Disease • How do we decide what’s going on? • What features in history are going to help? • Smoking • Age • Family history atopy • Personal history of atopy • Timing of symptoms/attacks • What caused this • Birth weight • SE class • Occupation

  12. Asthma defined as: Chronic inflammatory condition of the airways causing Hyper-responsive airways that narrow easily to a wide number of stimuli Narrowing is easily reversible In some patients inflammation may lead to irreversible airflow obstruction COPD defined as: Chronic, slowly progressive disorder Airways obstruction: Which does not change markedly over months Impairment largely fixed But partially reversible by bronchodilator therapy How do we start to differentiate between COPD & asthma

  13. Need spirometry to formally make the diagnosis • Asthma • Lung function may be normal when stable • Classically should see obstruction (FEV1/FVC ratio <70%) • Should see >400mls bronchodilation with salbutamol • Should see PEFR variability • COPD • Little variability • PEFR usually unhelpful but can EXCLUDE • Spiro- see obstruction (FEV1/FVC ratio <70%) • FEV1 (post BD values) predict severity

  14. NICE UK 2010 values

  15. Classification of COPD Severity by Spirometry Stage I: Mild FEV1/FVC < 0.70 FEV1> 80% predicted Stage II: Moderate FEV1/FVC < 0.70 50% < FEV1 < 80% predicted Stage III: Severe FEV1/FVC < 0.70 30% < FEV1 < 50% predicted Stage IV: Very Severe FEV1/FVC < 0.70 FEV1 < 30% predicted or FEV1 < 50% predicted plus chronic respiratory failure

  16. Global Strategy for Diagnosis, Management and Prevention of COPDCombinedAssessment of COPD When assessing risk, choose the highest risk according to GOLD grade or exacerbation history

  17. Not always Respiratory Cause BREATHLESSNESS

  18. Breathlessness • Anaemia • Heart Failure • Restrictive lung disease • Pleural effusions • Lung cancer • Pulmonary Embolisms

  19. Breathlessness • Anaemia • Heart Failure • Restrictive lung disease • Pleural effusions • Lung cancer • Pulmonary Embolisms

  20. Breathlessness • Anaemia • Common in (vegetarian) women • May be dietary in elderly • Often presentation of GI problems • Patient often pale • Syx may be similar to heart failure in susceptible individuals • Investigation • FBC

  21. Breathlessness • Anaemia • Heart Failure • Restrictive lung disease • Pleural effusions • Lung cancer • Pulmonary Embolisms

  22. Breathlessness • Heart failure • Very common • History • Breathless on exertion • Orthopnoea/paroxysmal nocturnal dyspnoea • Ankle oedema • Previous cardiac history- MI, hypertension, diabetes • Drugs-NSAIDS • Examination findings • Raised JVP • Gallop rhythm • Fine creps in lungs • Investigations • CXR • ECG • BNP • FBC • Echocardiogram

  29. Breathlessness • Anaemia • Heart Failure • Restrictive lung disease • Pleural effusions • Lung cancer • Pulmonary Embolisms

  30. Breathlessness • Common • Incredibly difficult to diagnose-often done as process of elimination • Symptoms • Chest pain • Haemoptysis • Unexplained breathlessness • Examination findings • May have pleural effusion • May have signs right heart strain • May have nothing! • Investigations • CXR • ECG • D-dimer • VQ scan • CT scan • CONSIDER • Patients with DVT • Malignancy • Recent surgery (esp pelvic) • Pelvic masses

  31. How do we assess and diagnose? OBSTRUCTIVE LUNG DISEASE

  32. RISK FACTORS for Obstructive Lung disease • ASTHMA • Family history • Atopy • Onset at young age • Exposure to allergens • Obesity • Smoking ( & maternal smoking) • Occupational triggers • Exhaust fumes & outdoor pollution • Low Birth Weight • COPD • Family History • Exposure to particles • Smoking • Occupational dust • Indoor pollution • Outdoor pollution • Small birth weight • Socio-economic status • Age • Respiratory infections • Inc Chronic Bronchitis • Asthma or Bronchial Hyper-reactivity

  33. Screening the pros and cons How Hard SHOULD WE LOOK FOR COPD?

  34. Diagnostic iceberg • Among smokers with no prior history of obstructive lung disease, 18.7% have COPD1 • Amongst patients currently treated with asthma therapy and no diagnosis of COPD, 24.5% have COPD Tinkelman DG, Price DB, Nordyke RJ, Halbert RJ. Misdiagnosis of COPD and Asthma in Primary Care Patients 40 Years of Age and Over. J Asthma. 2006;43:75-80.

  35. The unknown and undiagnosed COPD population: the UK An estimated 3.5 million people have COPD, but only 835,000 are diagnosed. This undiagnosed population represents a significant future healthcare and economic burden for England (Graph based on DH unpublished estimate, 2009). What is your prevalence in your practice population?

  36. ERS Sept 2011 P4138 Prevalence of chronic bronchitis in the Middle-East and North Africa: Interim results of the BREATHE study A. Khattab, A. Sayiner, J. Ahmed Khan, G. Iraqi, S. Nafti, A. Benkheder, B. Mahboub, M. L. Konisky, C. Nejjari, N. Rashid, The BREATHE Study Group (Cairo, Egypt; Izmir, Turkey; Karachi, Pakistan; Rabat, Fez, Morocco; Algiers, Algeria; Tunis, Tunisia; Dubai, United Arab Emirates; Beirut, Lebanon) Background: Few data are available on the epidemiology of COPD outside developed countries. Objectives: The objective of this epidemiological study was to assess the prevalence and burden of COPD, chronic bronchitis and smoking in eleven countries (Algeria, Morocco, Tunisia, Egypt, Jordan, Lebanon, Saudi Arabia, Syria, UAE, Pakistan and Turkey). Methods: A general population sample of 10 000 subjects ≥ 40yrs in each country was generated from random phone numbers. A structured interview was proposed to all subjects by telephone. Screening questions, including history of cough and sputum production, was used to identify subjects with chronic bronchitis. Individuals who smoked ≥ 10 pack-yrs and who had either chronic bronchitis or a previous diagnosis of COPD were considered to have possible COPD. In a subset of the study sample, assignment of COPD was confirmed by spirometry. This interim analysis assesses the prevalence of chronic bronchitis. Results: Of 118 039 subjects contacted, 44 892 were interviewed. 978 subjects reported having symptoms of chronic bronchitis.This corresponds to a prevalence of chronic bronchitis of 2.2% [95% CI: 2.0-2.3%], ranging from 0.6% [95% CI: 0.4-1.0%] in UAE to 2.9% [95% CI: 2.1-3.7%] in Algeria. The prevalence of chronic bronchitis was higher in women (2.4%; 95% CI: 2.2-2.6%) than in men (1.8%; 95% CI: 1.6-2.0%). Prevalence increased with age: 1.6% in subjects aged 40-49 yrs, 2.2% in those aged 50 to 59 yrs and 3.0% in those aged ≥ 60 yrs. Conclusion: The prevalence of chronic bronchitis in the Middle East and North Africa seems to be lower compared to other regions of the world.

  37. Can we identify risk factors? • Environmental risk factors • Cigarette smoking • Occupational exposure to dust chemicals et • Indoor fuel biomass • Indigenous • Ageing lung • Sex • Co-morbidities • Genetics- α1 antitrypsin defiency

  38. CIGARETTES • Pack Years • Helpful in assessing risk & exposure to cigarette smoke • Number of cigs per day x years smoked / 20 = pack years

  39. Effects of smoking on FEV1 100 Never smoked or not susceptible to smoke 75 Susceptiblesmoker FEV1 (% of value at age 25) 50 Disability 25 Death Predicted lifetime if patient stops smoking 25 50 75 Age (years)

  40. Current COPD severity in primary care: data from the Optimum Patient Care Research Database n = 19,425 Data on file, Optimum Patient Care: Price D. 2012

  41. Respiratory resource use prior to COPD diagnosis Years prior to COPD diagnosis Price et al. Presented IPCRG 2012

  42. Why diagnose?-data from Lung Health Group 2000 Lancet vol374 aug 2009

  43. Why Don’t we screen for COPD? • Hypertension • Hyperlipidaemia/CVS risk factors • Diabetes All have active and easily available screening programmes

  44. WHY SCREEN? • Recent estimates suggest COPD may exist in 40-50% of smokers & clinical consequences of mild disease has been under-estimated 1 • COPD is not just a disease of the lungs • Elevated levels of CRP/fibrinogen/leucocytes/TN alpha seen in patients with COPD2 1 2

  45. Diagnosis after spirometry:Glenfield Practice of 12,000 patients n=260 (prescribed bronchodilator therapy) Pre-study Post-study 70 60 60 50 44 Patients (%) 40 34 30 17 20 13 10 11 7 10 4 0 0 0 0 None COPD Mixed Other NRD Asthma Freeman D et al. Am J Respir Crit Care Med 1999

  46. Accuracy of GP Diagnosis in UK in patients over 40 receiving respiratory medication Freeman D, Price D et al ERS 2002

  47. So we can’t assume the patients are going to run into see us • Spirometry • Essential for diagnosis • How to start screening

  48. GOLD stage 1 therapy- stop smoking – prn SABA Does early therapy help?
