parietaria pensylvanica/hypersensitivity

The wide geographical distribution of parietaria in southern and western Europe is responsible for the high incidence of pollinic hypersensitivity. Our centre detected the existence of hypersensitivity to parietaria judaica in 250 patients (12.15%) out of a group of 2.057 patients. Exclusive

BACKGROUND Sublingual-swallow immunotherapy was recently recognized in the World Health Organization Position Paper (Allergen immunotherapy: therapeutic vaccines for allergic diseases) "as a viable alternative to parenteral injection therapy to treat allergic diseases" in adults. More controlled

Parietaria judaica and P. officinalis are the two most common subspecies of the Parietaria genus. P. judaica and P. officinalis have exhibited cross-reactivity in previous studies. P. judaica pollen is the main cause of allergy in the Mediterranean area. It

BACKGROUND Par j 1 represents the major allergenic component of Parietaria judaica pollen. Its three-dimensional structure is stabilized by four disulphide bridges. A family of three-dimensional mutants of the recombinant Par j 1 (rPar j 1) allergen, showing reduced allergenicity and retained T cell

We have evaluated the efficacy of azelastine, a new long acting antihistamine, in the topic treatment of seasonal allergic rhinitis to Parietaria officinalis. Forty five patients have been considered, 20 males and 25 females, mean age 28.5 years, suffering from seasonal rhinitis to Parietaria

We have evaluated the effect of formoterol in 28 patients (20 males and 8 females, mean age 25.4 years) affected by mild or moderate bronchial asthma due to Parietaria allergy. Inhaled formoterol was given at the dosage of 24 mg twice a day for 10 weeks during the pollen season. Patients had to

IgG antibody response to the inhalant allergen Parietaria judaica (Pj) and IgG subclass distribution were studied in 82 normal subjects, divided into three groups according to age (0-1, 1-20, and 20-60 years) and in 32 allergic subjects aged 20-60 years. Both normal and allergic subjects showed an

Forty patients, monosensitized to Parietaria judaica with a clinical history of at least two years of rhinoconjunctivitis with or without asthma, were selected and randomly allocated in two groups. According to an open controlled experimental plan, twenty patients were submitted to sublingual

In the Allergo-Immunological Centre of Rome University we selected 120 patients of both sexes, ranging from 5-65 years of age, affected by asthma and/or conjunctivitis without past or present history of nasal impairment (itching, sneezing, hydrorrhea). As a result of the allergometric tests carried

OBJECTIVE To define the prevalence of asthma and rhinitis in primary school children in the Polichni Municipality of the city of Thessaloniki. RESULTS The parents of 2005 students living in the area of Polichni completed a questionnaire for the detection of pulmonary disease in childhood. Of 493

The allergic rhinitis (AR) is an important risk factor for the development of asthma. In significant number of patients with AR, the non-specific bronchial hyperresponsiveness (BHR) could be demonstrated. It has been anticipated that these patients were at the greater risk for asthma. This study was

BACKGROUND Flow cytometry of the immune system so far has been limited to the analysis of subpopulations according to lineage markers. The cells involved in a particular immune response could not be assayed due to their low frequency. Here we show the potential of antigen-specific high gradient

Cova da Beira is an interior central region of Portugal, with a population of 93,000 inhabitants. The first pollen counts performed in Portugal revealed the highest values of the country in this area. The aim of this study was to assess the aeroallergens sensitization in an allergic population,

BACKGROUND Ocular allergies affect a great part of the general population and often co exist with other allergic manifestations. In the present study, the prevalence of allergic conjunctivitis and the commonest allergens in allergic patients at an outpatient unit in Thessaloniki, Greece were

Our patients with seasonal allergic rhinoconjunctivitis usually present severe clinical symptoms. A single daily dose of cetirizine 10 mg might be insufficient for these patients. To investigate this hypothesis we compared clinical efficacy and adverse side effects between two daily doses of
