The relationship between atopy and wheeze was examined in children, together with the possible influence on these conditions of parental atopy and family size. Children with a repeated history of wheezing were selected from an urban general practice population. The children, their first degree relatives, and a control group were examined for atopic status, atopy being defined as more than one p...

INTRODUCTION There are few studies investigating the association between BCG vaccination and atopy or asthma in adults. OBJECTIVE We investigated the association between BCG scar and the occurrence of atopy and asthma in Korean adults. METHODS We carried out a retrospective study of Korean adults who underwent skin prick testing, and, in some cases, spirometry and bronchial provocation test...

atopy can be defined as the genetically determined risk to develop allergic disease. avoidance of one specific allergen may decrease the risk for sensitization against this allergen, but it will not affect atopy. our aim was to investigate if exclusive breast-feeding is associated with atopic dermatitis during the first 5 years of life. data on 200 children were taken from parental-administered...

It is well known that the house dust and the scabies mites are related phylogenetically. We therefore performed atopy patch tests with house dust mite antigens (Dermatophagoides pteronyssinus (Dp) and/or Dermatophagoides farinae (Df)) in scabies patients without atopy and healthy controls. We studied 25 men with active scabies and 25 healthy controls. Skin prick tests with standardized house du...

Several hypotheses have been proposed to explain the etiopathogenesis of chronic fatigue syndrome (CFS), including immune dysregulation. However, few population-based prospective cohort studies have been conducted on CFS and atopy. We investigated the relationship between atopy and CFS by using a population-based cohort study. In this prospective, population-based cohort study of the National H...

BACKGROUND Family size and high birth order were related to the prevalence of hayfever and positive skin prick test. However, this association may be explained by maternal atopy. We examined the relationship between maternal atopy and the number of offspring in three European cohorts of pregnant women. METHODS The mothers and their children (n = 1487) were recruited for the Asthma Multi-centr...

METHODS. Aquestionnairewas used for assessment of patient demographic characteristics, familial atopy predisposition, and environmental exposures. In this case, familial atopy predisposition was determined on the basis of 2 factors: (1) a mother with self-reported atopy or allergen sensitization; or (2) atopy in a first-degree relative of the infant. Medical records were reviewed. Hospital leng...

Twenty six infants with a congenital immunodeficiency, characterised by failure of their sera to opsonise heat killed bakers' yeast for phagocytosis by normal polymorphonuclear leucocytes, were studied during infancy to determine the frequency of infection and development of atopy. They were compared with controls, matched prospectively for birth date, sex, parental smoking, and atopy and in wh...

the prevalence of atopic disease in recent decades has been dramatically increased. it has been suggested that bcg vaccination may protect against development of allergic diseases. the purpose of this study was to identifying relation between scar of bcg vaccine and atopy. this cross-sectional study was done in 1000 children, 10-15 years of age, in zanjan city. one thousand children (501 girls ...
