Different products vary greatly in efficacy and absorbability. If the steroids are not absorbed into the system, they can be safe and effective. Newer drugs – the leukotriene inhibitors are useful for some patients and less toxic. These inhalers work, but they are often addictive, since the bronchial tubes are likely to become constricted again when one dose wears off (the same pattern occurs when these drugs are sprayed into the nose to relieve nasal congestion). ![]() Other drugs of this class can be inhaled to relieve and prevent attacks. It can cause dramatic personality changes. Theophylline, derived from tea, has a long history of use, but may not be as safe as doctors used to think. Most bronchodilating drugs are stimulants that increase sympathetic tone and anxiety. Conventional treatments are sometimes the best choices for acute attacks, where immediate relief can be a life-and-death matter.įor allergic asthma, one of the safest and best drugs is inhaled cromolyn sodium. What are the conventional asthma treatments?Īsthma treatment has two aspects: management of acute attacks and long-term control or prevention. Children who breathe secondhand smoke are more likely to develop asthma, and among all youngsters with asthma, those who breathe secondhand smoke have more frequent attacks). The research was written up in the August, 2006, Scandinavian Journal of Immunology.ĭespite this intriguing evidence, we need a lot more proof from human studies before the hygiene hypothesis makes the leap from theory to fact, and I wouldn’t worry about a home being “too clean.” In fact, random pollution of the home environment has its own drawbacks. Instead, the wild rodents’ antibodies efficiently and effectively attacked invading organisms. All of the wild rodents had higher levels of IgG and IgE, classes of antibodies associated with immune and allergic diseases, but the wild rodents’ antibodies did not tend to bind to the rat’s own cells, as did the antibodies produced by the hygienically raised rodents. ![]() Researchers at Duke University Medical Center compared the antibodies in the blood of laboratory rats and mice, which grow in a virtually germ-free environment, with those of wild rats and mice. The hypothesis recently got a big boost in credibility. The idea is that the developing immune systems of less privileged kids are exposed to lots of germs from an early age and so become stronger and more protective of health. The hypothesis holds that children who grow up in crowded and dirtier environments are less likely to develop these ailments than youngsters raised in cleaner, more protected environments. The “hygiene hypothesis” is a proposed explanation for why allergies and asthma are now epidemic, especially in developed countries. ![]() It is now being considered an inflammatory disorder. The triggers for asthma can be primarily allergic or primarily emotional or induced by exercise or respiratory infection, or it can occur with no obvious causes. These muscles are controlled by nerves, but what triggers the nerves to make airways constrict inappropriately is not clear. The immediate cause of an asthmatic attack is tightening of the muscular bands that regulate the size of the bronchial tubes. If an attack is severe enough, it can kill. Asthma can appear and disappear without warning. Asthma symptoms can include wheezing (especially on expiration), coughing, and difficulty in breathing.
