INTRODUCTION Although the efficacy and safety of high dose hypoallergenic mite subcutaneous immunotherapy (SCIT) using a conventional administration schedule has already been demonstrated, there is no reported experience on the safety of these extracts with cluster schedules. We wanted to determine whether the use of a cluster schedule of a hypoallergenic allergen with a high concentration of h...

BACKGROUND The purpose of the study was to investigate the influence of environmental allergen exposure on allergic sensitization in infancy and early childhood. METHODS A cohort of 1314 newborns was recruited and followed up prospectively at the ages 12, 24, and 36 months. The levels of major mite (Der p 1 and Der f 1) and cat (Fel d 1) allergens were determined from domestic carpet dust sam...

The group chiefly consisting of mite fauna inhabiting house dust (floor dust and bed dust), stored product, house hold storages and granaries, bird's nest, cattle sheds and tho...

Typical symptoms nasal obstruction, sneezing, irritation, more often than pollen allergy, asthma also develops.

Scabies, a parasitic skin infestation by the burrowing "itch" mite Sarcoptes scabiei, causes significant health problems for children and adults worldwide. Crusted scabies is a particularly severe form of scabies in which mites multiply into the millions, causing extensive skin crusting. The symptoms and signs of scabies suggest host immunity to the scabies mite, but the specific resistant resp...

House dust mite allergy is present in up to 90% of Asian atopic patients, with increasing incidence and prevalence of sensitization and clinical allergy from childhood through to adulthood. This far exceeds the reported prevalence of 50%–70% in Western populations [1]. House dust mite allergy is particularly common in the tropical areas of Southeast Asia due to the warm, humid climate [2]. In c...

The aim of this study is to analyze the distribution characteristics specific allergens based on immunoglobulin E (IgE) test, performed using sera patients with allergic diseases in Shanxi region China. Sera from 3141 were analyzed immunoblotting for IgE antibodies inhaled and ingested allergens. association factors such as disease profile, sex, age, cosensitization who tested positive analyzed...

Life histories of "wild" house dust mites, Dermatophagoides pteronyssinus (Trouessart) (Acari: Pyroglyphidae), were compared with laboratory cultures by using a diet consisting of skin and dust or a laboratory diet consisting of dried liver and yeast. Under constant conditions of 25 degrees C and 75% RH, fecundity and rate of reproduction were higher in laboratory cultures on both diets compare...
