Active clinical trials for "Hypersensitivity"

Iodinated contrast agents (ICA) are widely used in medical imaging. They provide however a risk of immediate hypersensitivity reactions (IHS). The risk of anaphylactic shock is estimated at 1/100 000 injections. Nevertheless, for safety reasons and to limit undesirable effects, the reintroduction tests are not conducted along similar lines to throughout scan or arteriography. Moreover, reintroduction protocols are actually not standardized, in terms of injected volume and doses progression. It should be evaluated the relevance of the reintroduction tests with injection of a low volume and ensure the absence of reaction during the ICA injections Under real conditions. The investigators are assuming that the realization of a provocation test by intravenous reintroduction with a reduced dose of ICA improves the predictive value of IHS in comparison with only cutaneous tests.

The aim of this study is to assess the dermatological and ophthalmological tolerance of the investigational product Baume visage / Face balm RV4942A - RY1985 after 21 days of twice daily use on the study areas, under normal conditions of use. The aim of this study is also to: evaluate the cutaneous sensitivity by a stinging test at D1 T0 and D22. evaluate the cutaneous sensitivity by a sensitive scale at D1 T0, D1 Timm*, D8 and D22. evaluate the soothing efficacy by an efficacy questionnaire at D1 Timm*, D8 and D22. evaluate the cosmetic acceptability by a questionnaire at D22. This study is conducted as a national, monocentric, non-randomized open trial. The 33 subjects in this study (31 subjects on D22) present hypersensitive, reactive and intolerant skin on face. They are stinger subjects, with a dry to very dry skin. Timm*: 10 to 30 minutes after first application

The popularity of marathons and endurance events has increased over the last few decades and, interestingly, the demographics of participants have also changed. From 1980 to 2002 the average race time to complete the marathon lengthened from ~3.5 hours to ~4.5 hours. Likewise, many endurance races include "Clydesdale" and "Athena" divisions for heavier weight male and female runners, respectively. As such, there has been an increase of overweight and obese participants in these races. For example, one study consisting of 250 runners determined, according to BMI, that approximately 15% and 31% of the female and male participants, respectively, were classified as overweight, with 31% and 33% classified as obese. Therefore, many recreational endurance athletes are overweight despite their high level of activity. On one hand, these data are positive as regular exercise reduces cardiovascular disease and all-cause mortality in overweight and obese populations. Yet, it is well documented in sedentary obese individuals that excess adiposity can lead to disturbances in adipocyte lipolysis and altered substrate utilization at rest and during exercise, and can decrease muscle quality. However, it is unknown if overweight individuals that exercise regularly have disrupted fat metabolism, circulating hormones, or muscle quality. No study has directly determined if differences exist in fat metabolism, circulating hormones, and muscle quality between overweight recreational female athletes and their lean counterparts when training status is equivalent. Therefore, the purpose of this investigation is to determine if differences in pre and post-exercise fat metabolism, circulating insulin and growth hormone, and muscle quality exist between active overweight individuals compared to active lean individuals with similar training history and who have regularly trained for and participated in endurance events within the last few years.

The research aims to elucidate a specially-designed personalized diet that will increase gut colonization of Prevotella sp. and butyrate levels in pregnant mothers and the benefits in reducing infant's food allergy development.

Aluminium allergy is predominantly seen in children with small itchy nodules in the skin after vaccinations, so-called granulomas. We want to do an exposure study where aluminium allergic children have to eat aluminium pancakes for a short period of time. The purpose is to investigate whether a worsening of the children's symptoms can be detected, both itching of the granuloma, allergic rash on the skin and also the symptoms that are not measurable, such as headache, stomach ache and general agitation. We also want to examine the concentration of aluminium in the urine, which reflects the absorption of aluminum from the gastrointestinal tract.

Identification of biological markers able to better stratify cardiovascular risks in systemic lupus erythematosus patients is needed. We aimed to determine whether serum cardiac troponin T levels measured with a highly sensitive assay (HS-cTnT) may predict cardiovascular events in systemic lupus erythematosus.

Single-center, monadic, one day study utilizing the skin prick method to assess the allergy potential of Omeza Collagen Matrix in Human Subjects

The aim of this trial is to evaluate the effects of dairy product consumption on insulin sensitivity and pancreatic β-cell function in men and women at risk for the development of type 2 diabetes mellitus (T2DM) who habitually consume beverages high in sugar (non-diet sodas and fruit juice cocktails).

Grass pollen allergens are recognised as a major cause of allergic diseases in humans and animals. Worldwide, at least 40% of allergic patients are sensitised to grass pollen allergens and between 50-90% of hayfever or seasonal allergy sufferers are allergic to grass pollen. ToleroMune Grass is a novel, synthetic, allergen-derived peptide desensitising vaccine, currently being developed for the treatment of grass allergy. The purpose of this optional observational follow-on study is to further evaluate rhinoconjunctivitis symptoms on exposure to Grass in the EEU among subjects who completed all dosing visits in study TG002 approximately one year after the start of treatment.

Infants with protein sensitive colitis fed a nutritionally complete free amino acid-based medical food will be evaluated for 42 days.
