The prevalence of allergic diseases such as allergic rhinitis (AR) and asthma is markedly increasing worldwide as societies adopt western life styles. Allergic sensitization is an important risk factor for asthma and AR, and asthma often co-exists with AR. An estimated 300 million people worldwide have asthma, about 50% of whom live in developing countries and about 400 million people suffer fr...

Background: Asthma is a growing problem worldwide and the limitations of the current therapy for allergic asthma highlight the need for novel therapeutics. We conducted a systematic review and meta-analysis to find out the role of probiotics in the treatment of Asthma. <stron...

allergic asthma is a multifactorial disease, influenced by genetic and environmental factors. recent family-based studies have revealed evidence for linkage of human chromosomes 5q31-33, 12q15-24, 11q13 and 15q23.6 as regions likely to contain genes related to asthma. among the candidate genes in these regions are the genes encoding for human interleukin-4, interleukin-13 and interleukin-16. to...

INTRODUCTION The clinical efficacy of sublingual immunotherapy (SLIT) has already been proven and is known to be high. Its influence on the immunological system of patients suffering from bronchial asthma was also examined. However, it is still unclear how the polysensitisation, coexistence of other atopic disease and asthma treatment step influence the response to treatment with specific immun...

There is increasing evidence that inflammatory mechanisms other than eosinophilic inflammation may be involved in producing the final common pathway of enhanced bronchial reactivity and reversible airflow obstruction that characterises asthma. A review of the literature has shown that, at most, only 50% of asthma cases are attributable to eosinophilic airway inflammation. It is hypothesised tha...

Work-related asthma accounts for at least 10 percent of all cases of adult asthma. Work-related asthma includes work aggravation of preexisting asthma and new-onset asthma induced by occupational exposure. Occupational exposure to very high concentrations of an irritant substance can produce reactive airway dysfunction syndrome, while exposure to allergenic substances can result in allergic occ...

Asthma is a hereditary disease associated with IgE-mediated reaction. Whether maternal atopy and paternal atopy have different impacts on perinatal IgE production and asthma development remains unclear. This paper reviews and summarizes the effects of maternal and paternal atopy on the developmental aspects of IgE production and asthma. Maternal atopy affects both pre- and postnatal IgE product...

Alternaria alternata (AA) is an important mould in respiratory allergic diseases. The objective is to determine the prevalence of AA sensitization in respiratory allergic patients and to examine the annual variation of Alternaria spores. 824 patients between 5 and 65 years old with allergic rhinitis and /or asthma were enrolled. Prick tests were performed with two different standardized AA extr...

background: it has been suggested that helicobacter pylori infection might reduce the risk of atopic conditions, such as asthma, in childhood. this risk reduction could relate to the “hygiene hypothesis” which proposes an association between childhood exposure to microbes and risk of atopy. objectives: to examine the association between hp infection and childhood acquired asthma in sardinia. pa...
