What is new and topical in asthma?What is new and topical in asthma?
Inflammometry in asthma
Symptoms of asthma may be non-specific and may cross over with other syndromes
It can be difficult to treat for a number of reasons
Poor adherence to treatment regimeImprovement over time may be mistaken for
response to treatment
Corticosteroids should be used judiciously It makes sense to target asthma therapy to
underlying inflammation
InflammometryInflammometry
Eosinophilic airway inflammation reliably responds Eosinophilic airway inflammation reliably responds to corticosteroid therapyto corticosteroid therapy
Identifying and treating eosinophilic inflammation Identifying and treating eosinophilic inflammation can allow targeted use of corticosteroidscan allow targeted use of corticosteroids
Induced sputum is the investigation of choice for Induced sputum is the investigation of choice for identifying eosinophilic inflammation but its identifying eosinophilic inflammation but its availability is limitedavailability is limited

Vitamin D

illness)?enhanced steroid responsivenessDown regulation of atopy
Vitamin DVitamin D
Currently there is insufficient evidence of a causal Currently there is insufficient evidence of a causal association between vitamin D status and asthma to association between vitamin D status and asthma to recommend for or against vitamin D supplementationrecommend for or against vitamin D supplementation
But there is consistent evidence from observational But there is consistent evidence from observational studies that vitamin D protects against asthma studies that vitamin D protects against asthma exacerbations. exacerbations.
There is no evidence to support screening for vitamin D There is no evidence to support screening for vitamin D deficiencydeficiency

Chronic Obstructive Pulmonary Chronic Obstructive Pulmonary Disease (COPD)Disease (COPD)
The Asthma Foundation estimates that 1 in 7 New The Asthma Foundation estimates that 1 in 7 New Zealanders aged 45 and over has COPD - more than Zealanders aged 45 and over has COPD - more than 200 000 people, or the population of greater Hamilton (in 200 000 people, or the population of greater Hamilton (in Auckland 90 000)Auckland 90 000)

By 2030 chronic obstructive pulmonary disease is By 2030 chronic obstructive pulmonary disease is estimated to be the third most common cause of death estimated to be the third most common cause of death worldwide, a leading cause of hospitalizations, as well as worldwide, a leading cause of hospitalizations, as well as being one of the most expensive chronic diseases. being one of the most expensive chronic diseases.

COPD and heart diseaseCOPD and heart disease
According to a new investigation, individuals who suffer According to a new investigation, individuals who suffer with chronic obstructive pulmonary disease (COPD) or with chronic obstructive pulmonary disease (COPD) or those with reduced lung function have a serious risk of those with reduced lung function have a serious risk of developing cardiovascular disease.developing cardiovascular disease.
Presented at the European Respiratory Society's Annual Presented at the European Respiratory Society's Annual Congress in Amsterdam 2011, the discoveries indicate Congress in Amsterdam 2011, the discoveries indicate that because individuals with COPD and reduced lung that because individuals with COPD and reduced lung function appear to be at a significantly higher risk of function appear to be at a significantly higher risk of developing cardiovascular disease, they should be developing cardiovascular disease, they should be routinely screened for it. routinely screened for it.
