Oasys and Occupational Asthma

This website contains information on Occupational Asthma and a free multi award winning computer program called OASYS, which is used to help diagnose Occupational Asthma from serial peak flow records. Oasys shows further information and downloads for the Oasys program. References is a searchable database of more than 4,500 published papers in the field of occupational asthma. Causes shows some of the causes of occupational asthma. The Shield scheme reports some statistics for occupational asthma, mainly in the West midlands region, UK. BOHRF shows the evidence based occupational asthma guidelines for the UK. The interactive Case Histories are a learning resource for interested health professionals. There are also Medics, Specialists, Employers and Worker sections.

Comments for the page titled: "Normal non-specific reactivity excluded occupational asthma?"
This study reports a a very high sensitivity for non-specific reactivity in predicting a positive specific challenge test to an occupational agent. Most of those with negative NSBR were away from exposure at the time of the test, something generally found by others. The high sensitivity is partly explained by using a higher cut-off for normality (16mg/ml) than the usual 8mg/ml, but this is still unlikely to explain the very high sensitivity found. We need assurance that NSBR was not used to decide who should have a specific challenge (this is recommended in some guidelines). Another possible explanation is the high prevalence of the eosinophilic phenotype, something associated with NSBR. Others have found much lower sensitivities for NSBR in predicting the response to specific challenges, particular in those without sputum eosinophilia. The specificities quoted depend on the controls selected (or in this case those with negative specific challenges) as NSBR cannot separate occupational from non-occupational asthma.

Comments for the paper: "Prevalence and risk factors for COPD in farmers: a cross-sectional controlled study", 2016, Eur Respir J
Farmers working with pigs and cattle have more COPD than crop farmers or non-farming controls. This is the opposite effect for asthma for which exposure to cattle in the first year of life is protective

The Website

This website is run by the Oasys research group, part of the Midland Thoracic Society, UK. We are an independent group of clinicians and researchers, and run a clinical service for workers with occupational lung disease as part of the British National Health Service. We have developed the Oasys program to help ourselves and others in the diagnosis of occupational asthma. We have no specific funding, relying on research grants and the enthusiasm of our group. The website is written by Cedd Burge, who receives some funding from the group. The group meets about every 6 weeks on a Wednesday evening, as shown below.
