Moulds increase severity of asthma
August 21, 2002Severe asthma in adults may be associated with sensitivity to airborne moulds rather than pollens, finds a study in this week's BMJ.
Researchers used data from 1,132 people with asthma from the European Community respiratory health survey to access whether the severity of asthma is associated with sensitisation to airborne moulds rather than to other allergens, such as pollens and cats.
Sensitisation to moulds was significantly associated with severity of asthma, but the team found no association between severity of asthma and sensitisation to pollens or cats.
The small size of fungal spores may allow them to reach the lower airways, suggest the authors. Unlike pollens, moulds are also present through the year with increase in the spore counts during the autumn months. Furthermore, the level of mould exposure is probably greater because the exposure occurs indoors rather than outdoors and people spend most of their time indoors.
Those people with asthma who are sensitised to airborne moulds should be educated to pay careful attention to symptoms and comply with treatment, particularly during the seasonal increase in mould spore counts, say the authors.
Patients should also be encouraged to decrease exposure by avoiding indoor conditions that facilitate the growth of moulds - for example, by better ventilation and by decreasing dampness, they conclude.

Asthma in boys may be just a phase, but for girls it may be there to stay
Boys may be more apt than girls to have childhood asthma, but, when compared to girls, they are also more likely to grow out of it in adolescence and have a decreased incidence of asthma in the post-pubertal years. This indicates that there may be a buried mechanism in asthma development, according to a prospective study that analyzed airway responsiveness (AR) in more than 1,000 children with mild to moderate asthma over a period of about nine years.

Students with food allergies often not prepared
College students with food allergies aren't avoiding the foods they know they shouldn't eat. Students of all ages are not treated with potentially life-saving epinephrine as often as they should be.
