Filter by:Background: Studies have noted a correlation between food sensitivities and health disorders. Various commonly seen health problems may be caused by cane sugar since it is lavishly and frequently used by people worldwide. Objective: This study evaluated the efficacy of NAET testing instruments in detecting hypersensitivities to cane sugar. Materials and Methods: Seventy-four subjects volunteered for this study. They were asked to write down one of their major health problems, the amount of sugar consumed on a daily basis and any known health problem(s) related to sugar consumption. The following testing modalities were used in the study: (1). Allergy Symptom-Rating Scale (ASRS); (2). NST Rating Scale (NSTRS); (3). Pulse Difference Rating Scale (PDRS). Test-1 was done twice. Tests 2 and 3 were done three times each: once without contacting sugar and then contacting sugar at one minute and ten minutes.
The trial is performed to assess efficacy and safety of a purified standardised wasp venom preparation in wasp venom allergy
There has been considerable debate over the last 30 years about the interaction between asthma and parasitic infection. It has been suggested that at least part of the reason for the increasing prevalence of asthma in the developed world is a decrease in parasite infections resulting from improved living conditions with economic development. Our previous studies in Ethiopia suggest that hookworm infection may be particularly important in this process. To establish definitively whether parasites can protect against allergic disease, and specifically asthma, ultimately requires a randomised clinical trial of parasite infection in patients with asthma. We, the researchers at the University of Nottingham, have completed a study in normal volunteers to establish the dose of hookworms necessary to generate infection at the level shown to be protective in population surveys, and shown that infection is well tolerated. We now propose two randomised placebo-controlled double blind clinical trials. The first will test the effectiveness of hookworm infection in reducing symptoms in allergic patients with rhinitis, and will also serve to allow us to check the likely safety of hookworm infection in asthma. Assuming that the results of this study are favourable, we will then carry out a trial of hookworm infection in asthma. We will also take the opportunity during both of these studies to investigate the cellular mechanisms of the effect of hookworm infection on the immune system.
This trial is performed to assess the efficacy and safety of the ALK Grass tablet for treatment of grass pollen induced rhinoconjunctivitis (hayfever).
The purpose is to find out if Icleen IQAir, HEPA-filter air cleaners with high capacity and pre-set speed functions, have a beneficial effect on patients with asthma and allergy to dogs. Air cleaners will be installed in the bedrooms and living rooms in the homes of children and adolescents aged 8-17 years at the study entry, with allergy to dogs, but not to house dust mites. The investigators will look upon the significance of this study, and of a previous study with a similar design and the same main parameters to find out if this trial supports the results of the first trial by the same project leader, or makes it likely that the seemingly beneficial effects of the first study occurred by chance. Main parameters: - hyperventilation cold air challenge test Supportive parameters: - serum ECP - symptom scores The trial will be a parallel, double blind placebo controlled one.
Although asthma is likely to be a heterogeneous disease or syndrome, three factors and/or events repetitively emerge for their ability to significantly influence asthma inception in the first decade of life: immune response aberrations, which appear to be defined best by the concept of cytokine dysregulation; lower respiratory tract infections (in particular RSV); and some form of gene by environment interaction that needs to occur at a critical time period in the development of the immune system or the lung. It remains to be firmly established, however, how any one or all of these factors, either independently or interactively, influence the development of childhood asthma. Thus, our efforts to determine and define the importance of these three factors to asthma pathogenesis are the focus and goal of this current grant application.
Seasonal/perennial allergic rhinitis (SAR/PAR) is a common childhood illness. One of the leading therapies for the treatment of SAR/PAR is intranasally inhaled corticosteroids (ICS). One of the major long-term safety concerns is whether ICS interferes with normal growth in allergic rhinitis children. Recent evidence suggests that nasal ICS may cause decreased growth. However, the effect of nasal ICS on long-term growth and the attainment of final adult height is unknown. Another potential systemic adverse effect of ICS use is suppression of the hypothalamic-pituitary-adrenal axis function. The primary hypothesis of this study is that triamcinolone acetonide aqueous nasal spray (TAA) will have no effect on measured adult height in relation to target adult height in children with allergic rhinitis.
A series of allergy shots may reduce symptoms of seasonal ragweed allergies. This study will determine whether taking a drug called omalizumab (also known as Xolair) before getting the allergy shots is more effective than allergy shots alone or other treatments, such as prescription antihistamines.
Controlled trial of an intervention to reduce indoor exposures to cockroach allergens among asthmatic children in NYC.
This study is designed to investigate whether exposure to particulate air pollution increases the allergic response to allergens. Research studies suggest that symptoms in individuals with allergies may be aggravated by exposure to particulate air pollution. We sought to experimental determine this by exposing human volunteers to combustion particles, a component of air pollution, and then challenge them with an allergen such as ragweed or oak tree pollen. Using biological tests we can measure whether the allergen response is magnified by prior particulate exposure.
