HEALTH AND LIFESTYLE 1. Can we talk nowadays about a global allergy epidemic? Is the modern obsession with hygiene responsible for it? Read the text below and explore the causes responsible for this condition: An epidemic is sweeping the Western world. The symptoms vary: sneezing, rashes, swollen eyes and breathlessness. An inexorable rise in allergies is emerging as a serious threat to the health of future generations. If this continues, allergy experts warn that it could become one of the biggest medical challenges of the next century. It has long been suspected that our hygiene-obsessed modern lifestyle is to blame. But immunologists are now revealing precisely how reduced exposure to bacteria and parasitic worms is damaging the immune system’s ability to regulate itself. Immune responses that evolved in the presence of certain microbes have been thrown wildly out of kilter in their absence. As a result, the body’s defences have become dangerously over-sensitive to things like dust, pets and foods. Several explanations have already been proposed, from increased exposure to allergy triggers in carpeted homes and polluted cities to changes in diet, obesity and breastfeeding patterns. The theory that gained most credence, however, was the ‘hygiene hypothesis’, first proposed in 1989. Observing that allergies were less frequent among people who had serious illnesses during childhood, David Strachan, an epidemiologist at St George’s Hospital Medical School, London, argued that modern immune systems were ill-prepared due to the reduction in serious childhood infection. In other words, in the confines of our antiseptic modern lifestyle, the immune system falls idle, fails to mature properly and attacks harmless foreign molecules, creating all sorts of self-destructive reactions. Then, in 1995, the discovery of regulatory T-cells, specialist cells that function exclusively as a brake on the attack cells, revolutionised the way we view the body’s defences. Studies have shown that mice with respiratory allergies get better when treated with dead Mycobacterium vaccae, a harmless bacterium found in mud. Such studies also suggest that the shift to an antibacterial lifestyle may have caused this disruption of immune development, isolating the body from those friendly microbes. The next step is to identify which microbes are responsible for this all-important schooling of the immune system. To that end, immunologists are focusing on the microbes that humans encountered on a daily basis back when we drank from streams and toiled among soil and farm animals. It was in their company that our defence mechanisms evolved, after all. Immuno-biologists are exploring the effect of helminths on allergic responses in humans, and the early clinical trials are providing encouraging results. Meanwhile, a recent German study – in which mice exposed to barnyard microbes gave birth to allergy-resistant offspring – indicates that exposing pregnant women to such microbes may protect their children. Elsewhere, allergy experts recommend probiotics as a way of smuggling the good bacteria into the body. And most agree that hygiene needn’t be so absolute. Experts are optimistic about the discovery of the immunological elixir that lurks on the farms and in the guts of allergy-resistant people across the developing world. It should then be possible to find ways to re-educate our frontline troops in the complex art of immunological warfare. (Adapted from http://www.sciencefocus.com/) 2.
