12 Definition of asthma Diagnosis and natural history. Thorax 2003; 58 (Suppl I): i1-i92 “A chronic inflammatory disorder of the airways … in susceptible individuals, inflammatory symptoms are usually associated with widespread but variable airflow obstruction and an increase in airway response to a variety of stimuli. Obstruction is often reversible, either spontaneously or with treatment.”

13 Diagnosis  The diagnosis of asthma is a clinical one  There is no standardised definition, therefore, it is not possible to make clear evidence based recommendations on how to make a diagnosis  Central to all definitions is the presence of symptoms and of variable airflow obstruction

14 Diagnosis  Base initial diagnosis on a careful assessment of symptoms and a measure of airflow obstruction  Spirometry is the preferred initial test to assess the presence and severity of airflow obstruction (use PEF if spirometry not available) PEFR – spirometry unavailable occupational monitoring

15 Following clinical assessment in adults

16 Features that increase the probability of asthma in adults  >1 of the following: wheeze, breathlessness, chest tightness, cough, particularly if:  worse at night and early morning  in response to exercise, allergen exposure and cold air  after taking aspirin or beta blockers  Personal/family history of asthma/atopy  Widespread wheeze heard on auscultation of the chest  Unexplained low FEV 1 or PEF  Unexplained peripheral blood eosinophilia

17 Features that lower the probability of asthma  Prominent dizziness, light-headedness, peripheral tingling  Chronic productive cough in the absence of wheeze or breathlessness  Repeatedly normal physical examination of chest when symptomatic  Voice disturbance  Symptoms with colds only  Significant smoking history (>20 pack-years)  Cardiac disease  Normal PEF or spirometry when symptomatic

18 Following clinical assessment in adults

21  Start treatment at the step most appropriate to the initial severity of their asthma  Aim is to achieve early control  Step up or down with therapy  Minimal therapy Before initiating new drug therapy:  Compliance  Inhaler technique  Eliminate trigger factors

22 Control of asthma, defined as:  No daytime symptoms  No night time awakening due to asthma  No need for rescue medications  No exacerbations  No limitations on activity including exercise  Normal lung function (FEV 1 and/or PEF >80% predicted or best) with minimal side effects.

23 Factors that should be monitored and recorded:  Symptomatic asthma control using RCP ‘3 questions’, Asthma Control Questionnaire or Asthma Control Test (ACT)  Lung function (spirometry/PEF)  Exacerbations  Inhaler technique  Compliance (prescription refill frequency)  Bronchodilator reliance (prescription refill frequency)  Possession of and use of self management plan/personal action plan

24 Factors that should be monitored and recorded:  Symptomatic asthma control using RCP ‘3 questions’, Asthma Control Questionnaire or Asthma Control Test (ACT)  Lung function (spirometry/PEF)  Exacerbations  Inhaler technique  Compliance (prescription refill frequency)  Bronchodilator reliance (prescription refill frequency)  Possession of and use of self management plan/personal action plan

27 Inhaler devices

28  Prescribe inhaled short acting β 2 agonist (SABA) as short term reliever therapy for all patients with symptomatic asthma  Good asthma control is associated with little or no need for short-acting β 2 agonist  Using two or more canisters of β 2 agonists per month or > puffs per day is a marker or poorly controlled asthma that puts individuals at risk of fatal or near-fatal asthma  Patients with high usage of inhaled short-acting β 2 agonists should have their asthma management reviewed

29

30  Inhaled steroids are the recommended preventer drugs for adults for achieving overall treatment goals  Consider inhaled steroids if any of the following:  Using inhaled β 2 agonist three times a week or more  Symptomatic three times a week or more  Waking one night a week  Exacerbation of asthma in the last two years (adults and 5-12 only)

31  Adults:  mcg/day BDP*(reasonable starting dose 400mcg per day for many adults)  Start patients at a dose appropriate to the severity of the disease  Titrate the dose to the lowest dose at which effective control of asthma is maintained

32 SteroidEquivalent dose (mcg) Beclomethasone CFC 400 Beclomethasone Clenil400 Qvar Fostair200 Budesonide Symbicort400 Fluticasone Seretide200 Mometasone 200 Ciclesonide

33

34  A proportion of patients may not be adequately controlled at step 2  Check and Eliminate  Adults and Children 5-12:  First choice as add-on therapy is an inhaled long-acting β 2 agonist (LABA), which should be considered before going above a dose of 400mcg BDP* and certainly before going above 800mcg

35

36  Can’t miss their ICS  More convenient  Increased compliance  Pathophysiology?  Different inhalers – different deposition  Interaction occurs at single cell level  Deposition varies from one inhalation to the next

37

38  If control remains inadequate…

39

40  Still uncontrolled..  Monitor - Blood pressure DiabetesHyperlipidaemiaBMD

41  Steroid sparing medication -Methotrexate -Ciclosporin -Oral Gold ColchicineIVIG Subcutaneous Terbutaline Anti- TNF

42  Stepping down therapy once asthma is controlled is recommended  Regular review of patients as treatment is stepped down is important  Patients should be maintained at the lowest possible dose of inhaled steroid  Reductions should be slow, decreasing dose by ~25- 50% every three months

43

44  Miss BL1984  Admission Sep 2006  Exacerbation asthma, PEFR 200 l/min (normal 450)  Recent LRTI  1 Admission to hospital this year, usual control adequate  Known panic attacks – this different

45 ?? Regular meds – becotide AAt university, smokes!..moderate alcohol! AAcute management? SSteroids, ICS, ventolin, RNS, OPD

46  Clinic October 2006  Good recovery, still some SOBOE, started attending gym.  Nocturnal symptoms – none  Ventolin – three times per week.  What to do?

47  Lifestyle advice  Compliance  RNS - Management Plan, Education  Pre-dose with ventolin  LABA - Combination inhaler

48

49 Patient preferences:  Treatment as simple as possible  Few inhalers  Lowest dose of steroid to control symptoms  Avoid hospitals when possible  Minimise symptoms Haughney J et al ERS 2006 UK qualitative and quantitative study to evaluate patient understanding of their asthma and determine patient preferences regarding the delivery of asthma care and treatment.

51 Desfougeres JL et al. Eur Respir J 2007:30 (supple 51):249s 40% of Not Well- Controlled patients consider themselves “Well” or “Completely Controlled” Self-reported level of control by Not Well-Controlled patients % Patients

52  Mrs TL24/10/1984  Clinic Jul 2006  Asthma age 12  2 x pregnancies – deteriorated during, brittle++ (Newcastle)  BIH  Night waking, morning dipping, wheeze, SOB – 10/40

53  Guinea pig and rabbit, shop assistant.  Bec puffs bd, SV 4 puffs bd, ventolin and combivent prn.  SaO 2 98%, 2.69/3.58 (3.21/3.68).  What to do?

54  Write to chest consultant  RNS review – management plan, education  QVAR - Thrush  Combination inhaler - tried  ?LTRA  ?Nebuliser  Standby steroids

55  Clinic Aug 2006  Stable  2.84/3.67 litres  Plan – no change  DNA…

56  23-year old woman with history of childhood asthma  Started fitness campaign but suffers from breathlessness on exertion  At clinic, PEF normal

57 What advice would you give Laura? What therapy would you recommend if a peak flow diary showed a stable baseline but short lived dips after running?

58 Remember to make an assessment of the probability of asthma. Diagnose before treating – try to confirm diagnosis with objective tests before long term therapy is started.

59  Increasing symptoms – some help from blue inhaler  Interested in complementary therapy - Buteyko  Husband noticed night time coughing – keeping him awake! What would you advise Laura about complementary treatments for asthma?  Becomes pregnant.

60 What would you do now if she was: (a)not distressed, slightly wheezy with respiratory rate of 20 breaths/minute, pulse 100 beats/minute and PEF of 390 L/minute? (b) looks dreadful, cannot complete sentences, with very quiet breath sounds on auscultation, respiratory rate 30 breaths/minute, pulse 120 beats/minute and PEF of 120 L/minute?

61  No consistent evidence to support use of complementary or alternative treatments in asthma  Continue usual asthma therapy in pregnancy  Monitor pregnant women with asthma closely to ensure therapy is appropriate for symptoms.
