Q

How do you diagnose asthma in adults with spirometry?

A

If pre BD spirometry shows obstruction (FEV1/FVC ratio <0.7) perform reversibility with SABA
12% (and >200mls) increase in FEV1

Q

How do you diagnose asthma in adults with peak flow diary?

A

Complete 2-4 week peak flow diary
Evidence of 20% peak flow variability supports asthma diagnosis.
Once on treatment with ICS expect peak flow to increase and variability reduce

20
Q

Diagnosis asthma in children

A

Peak flow diary (1-2 week) age 5-17
Skin prick test, Allergen-specific IgE, Blood eosinophils age 3-17
Spirometry with reversibly testing age ≥ 12
Fractional exhaled Nitric Oxide (FeNO) age ≥ 12

21
Q

If no objective evidence but strong clinical suspicion asthma in children?

A

Perform treatment trial
Including in children age 3-5 years
with “episodic wheeze”:
* Commence ICS for 8 weeks: Clenil
modulite 200mcg BD
* Review response at 8 weeks

No response
- Discontinue treatment
- Consider alternative diagnosis
Positive response
- Discontinue treatment
- If symptoms recur, restart low dose
ICS as maintenance therapy

22
Q

How to differentiate asthma from COPD

A

Asthma: response to SABA>200 mL and >12% improvement of FEV1.

Completely reversible airway obstruction do not have COPD

If a patient with a high clinical suspicion of asthma, consider a trial of 40 mg of prednisolone OD for 2 weeks, then repeat spirometry.

23
Q

Features bronchiectasis

A

Permanent abnormal dilatation of the airways
Impaired mucociliary clearance
Excessive inflammation of airways, mucus production, and bacterial colonisation.

chronic productive cough.
unexplained haemoptysis
Exertional dyspnoea
Recurrent chest infections
Signs of over-inflation of chest
Finger clubbing (now rare)
Pseudomonas on sputum culture

24
Q

Underlying causes bronchiectasis

A

Post TB, Measles, pertussis, pneumonia
Cystic fibrosis
COPD
IBD, RA

25
Diagnosis of bronchiectasis
CXR to exclude other causes Spirometry Sputum High resolution CT when well
26
Referral criteria bronchiectasis
first isolate of Pseudomonas aeruginosa, or atypical mycobacteria. persistent haemoptysis. spirometry shows moderate to severe airflow obstruction or declining lung function over time. recurrent exacerbations (>3 per year) known immune deficiency, IBD, RA, or allergic bronchopulmonary aspergillosis (ABPA). considering long‑term antibiotic therapy.
27
CRB-65
Confusion RR>30 BP: Systolic <90 or Diastolic <60 Aged 65 years or older If >1 then admit
28
Ix for LRTI
Treat empirically/based on prev sputum for 72 hrs If no improvement: CXR, bloods, sputum culture, consider admission
29
Features COPD
airflow obstruction on spirometry, and a history of smoking, or exposure to other noxious agents. cough up phlegm or mucus most days. lose breath more easily than others their age. suffer recurrent episodes of winter chest infections.
30
COPD findings on spirometry
Reduced FEV1 (<80% predicted) Reduced FVC (but to a lesser extent than FEV1) FEV1/FVC ratio reduced (<0.7) Mild – FEV1 more than 80% predicted Moderate – FEV1 50 to 80% predicted Severe – FEV1 30 to 50% predicted Very severe – FEV1 less than 30% predicted
31
Non inhaler management COPD
Vaccination (flu, COVID, pnuemococcal) Exercise + pulmonary rehab Smoking cessation Referral for oxygen assessment if SpO2 is <93% and not smoking Mucolytic – carbocisteine 750 mg twice a day.
32
COPD management
Phenotype 1- Dyspnoea with less than 2 exacerbations per year LABA + LAMA (Anoro Ellipta 55/22 T OD) Phenotype 2- Two or more exacerbations per year Prescribe Triple therapy (trelegy OD, trimbow BD) Phenotype 3- asthma overlap Significant symptomatic or lung function response to steroids. Blood eosinophil counts >0.3 MART plus LAMA (symbicort turbohaler 200/6 TT BD + spiriva respimat TT OD)
33
COPD exacerbation management
SABA PRN Prednisolone (30mg OD 5 days) Abx if increased sputum purulence, volume + breathlessness
34
Referral criteria COPD
diagnostic uncertainty. patient younger than 40 years, or younger than 55 years with severe disease. >2 exacerbations a year. considering pulmonary rehabilitation. considering nebulised therapy
35
Differential diagnoses for cough
Asthma Gastro‑oesophageal reflux –worse lying down to sleep, after meals, dysphonia. Postnasal drip Malignancy – weight loss, dysphonia, dysphagia ACEi Cardiac – dyspnoea, palpitations, ankle swelling.
36
Cough>8 weeks
USC referral if unexplained haemoptysis or weight loss/hoarseness CXR Consider sputum culture x3 (MC+S, acid‑fast bacilli, and fungi) Consider spirometry Treat underlying cause (eg trial nasal steroid, asthma treatment, PPI)

Causes haemoptysis
lung cancer. TB bronchiectasis pulmonary abscess. Minor haemoptysis: LRTI PE anticoagulant or antiplatelet treatment. CCF/ mitral stenosis – pink frothy
