Allergic diseases may come in a series called the ‘allergic march’. A proportion of adults and children with one type of allergy will progress to other allergy types or even asthma later in life. Thus, the development of allergic diseases can be a life-long struggle.
The co-existence of asthma and rhinitis in allergic patients is common: 75-80% of asthma patients also have rhinitis, and an estimated 19-38% of patients with rhinitis have asthma.
Several studies have shown that allergy vaccination reduces the risk of developing additional allergies and asthma. Allergy vaccination is the only treatment that holds a potential to stop the allergic march.
