Q

Describe genes and asthma in children

A

Genes contribute to 30-80% of causation
10 variants that can make contribution
Genes can include ADAM33 and ORMDL3 but people can have these and not have asthma
These genes interact with the environment
Epigenetics can be the reason for this

Q

Explain allergy and asthma

A

Allergy probably does not cause asthma but a primary epithelial abnormality in skin/gut/airway can result in -eczema/asthma etc. and allergy.
The allergy then fuels eczema/asthma etc.

Q

What is a exhaled nitric oxide test?

A

Is unproven to diagnose asthma in children
It measures the amount of nitric oxide that is exhaled from a breath. Increased levels of nitric oxide are associated with swelling of lung airways

Q

What does treatment for asthma look like in children?

Q

What are some benefits of asthma treatment?

A

Helps diagnosis
If symptoms are responding
Improves QoL
Reduces risk of attacks

24
Q

What is the approach to a reported wheeze?

A

Is it genuine - whistle, sleep disturbance
Can watch and see if continues or trail with treatment
If treatment helps then asthma - remember Easter holiday

25
Q

What can be a differential diagnosis for asthma in under 5s?

A

Congenital
Cystic Fibrosis
Primary ciliary dyskinesia
Bronchitis
Foreign body

26
Q

What can be a differential diagnosis for asthma in over 5s?

A

Dysfunctional breathing
Vocal cord dysfunction
Habitual cough - chronic cough with no underlying cause or diagnosis
Pertussis - highly infectious airway infection

27
Q

What is the difference between asthma and VIW?

A

They are the same condition
99% of VIW is preschool children
These is no intervals of wheezing in VIW
Both treated with bronchodilators

28
Q

What is the approach to preschool cough?

A

Is it an associated wheeze - yes then wheeze algorithm
no then is it moist/dry
Dry - watch and see
Moist - if shows red flags then might be bronchiectasis
no then bacterial bronchitis or other related diseases

29
Q

What is treatment to mild asthma in children?

A

SABA via spacer
SABA via spacer + prednisone

30
Q

What is treatment to moderate asthma in children?

A

SABA via nebulizer + prednisone
SABA + ipratropium via nebulizer + prednisone

31
Q

What is the treatment to severe asthma in children?

A

IV salbutamol
IV aminophylline
IV magnesium
IV hydrocortisone
Intubate and ventilate

32
Q

What do you do in acute asthma?

A

Start treatment and reassess in 1 hour
Step up or down where appropriate

33
Q

What type of steroids are used in chronic/maintenance treatment?

A

Inhaled steroids

34
Q

What type of steroids are used in acute treatment?

A

Oral steroids

35
Q

What are the steps for treating acute asthma in children?

A

The level of treatment is determined by symptoms and sats
Treat and reassess
Be guided by sats/O2 requirement

36
Q

What are the goals to treating non acute asthma?

A

Minimal symptoms during the day and night
Minimal need for reliever medication
No attacks/ exacerbations
No limitation for physical activity

37
Q

How do we measure control?

A

Closed questions
Use SANE
Short acting beta agonist/week
Absence from school or nursery
Nocturnal symptoms/week
Exertional symptoms

38
Q

When would you reduce treatment?

A

Reduce treatment if symptom free for 3 months and watch to see result

39
Q

What is the step up step down approach?

A

Started on low dose ICS - severe may respond to minimal treatment
Review after 2 months - need an inhaler holiday

40
Q

What are the classes of medication used in non acute asthma?

A

SABA - blue relieving inhaler
Inhaled corticosteroids (ICS)
Oral steroids
LABA, Leukotriene receptor antagonists and theophylline are add ons

41
Q

What is the contrast with adults for treatment in non acute asthma?

A

Max dose ICS 800 micrograms in under 12s
No oral B2 tablet
LTRA first line preventer in under 5s
No LAMAs
Only two biologicals

42
Q

What treatment would you give to a child taking a B2 agonist more than 2 days a week and being symptomatic for 3 days or waking one night a week?

A

Start with very low dose of inhaled corticosteroids or LTRA in under 5s

43
Q

What are benefits of ICS?

A

Useful for diagnosis
Very effective when taken
Very safe when correctly prescribed

44
Q

What are the dose response for ICS on a graph?

A

If increased from 200 to 400 the positive effects increase, but doubling after will not change positive effects

45
Q

What are the dose response for ICS on a graph?

A

If increased from 200 to 400 the positive effects increase, but doubling after will not change positive effects
Also there is not much increase in adverse effects if you increase drug

46
Q

Adverse effects of ICS?

A

Height suppression
Maybe oral candidiasis
Adrenocortical suppression
No hypertension or cataracts

47
Q

What are two thing to remember with LABA?

A

Do not use without ICS
Used as fix dose inhaler
Is an add on preventer

48
Q

What is leukotriene receptor antagonist?

A

Montelukast only in children
Rule of thirds - 1/3 benefits, no benefits or no change
Better adherence to oral
Granules for reluctant toddlers

49
Q

What happens if symptoms continue into step 3 of BTS/SIGN guidlines?

A

Add on LABA but keep open mind
Additional add on therapies include increasing ICS and LTRA

50
Q

Describe severe asthma in children?

A

Experimental medicine
50% psychological issues
Less than 50% compliance issues
Question the diagnosis
Minority with genuine severe disease
Role of biologics unproven

51
Q

What are the two types of delivery systems for non acute asthma?

A

MDI (metred dose inhaler) with spacer
Dry powder device

52
Q

What 3 things make taking an MDI more effective?

A

Taking MDI with a spacer - 4x more lung deposition
Shake inhaler between puffs
Wash spacer monthly to reduce static

53
Q

Explain dry powder devices?

A

Licensed in over 5s, under 8s cannot use them
Achieve 20% lung deposition

54
Q

What is the advantages of MDIs over nebulisers?

A

Quieter, quicker, valve mechanism. don’t break down, portable and cheaper

55
Q

What are some non-medical interventions that can help non acute asthma?

A

Stop tobacco smoke exposure
Remove environmental triggers - pets, HDM had to eliminate
