Chronic urticaria (CU) is a disease that usually affects a large visible amount of surface of the skin. It is accompanied by severe itch and feeling of burned skin. Therefore the disease has a big impact on the quality of life of patients. Unfortunately, to date CU is not easily controlled by its few existing treatment options (i.e. antihistamines, omalizumab, cyclosporine). This research's main perspective is to improve quality of life for CU patients by first of all focusing on a good clinical diagnosis of (different subtypes of) CU in a CU reference center, and secondly by gaining more insight on the pathogenesis of the disease to expand knowledge on potential new targeted treatments for the patients.
Blood samples from urticaria patients will be analyzed for viral particles
Chronic spontaneous urticaria is an inflammatory disease which is characterized with intermittent or daily urticaria. This diseases lasts for more than 6 weeks. Several recent studies have suggested a role for vitamin D in modulation of immune system and pathogenesis of chronic urticaria.
This Study is to evaluate the utility of prospective HLA-B*1301 screening on the incidence of dapsone hypersensitivity syndrome (DHS) in 3130 previously Dapsone(DDS)-naive patients. Those patients include allergic cutaneous vasculitis, urticaria, psoriasis, acne, bullous skin diseases, sterile pustulosis, leprosy, pneumocystis pneumonia and any other patients who need dapsone administration. The study has two (co-primary) objectives: i) to determine if screening for HLA-B*1301 prior to DDS-containing treatment results in a lower incidence of clinically-suspected DHS versus current standard of care (no genetic screening) and ii) to determine if screening for HLA-B*1301 prior to DDS-containing treatment results in a significantly lower incidence of immunologically-confirmed DHS versus current standard of care (no genetic screening or patch testing). The study consists of up to a 5-day screening period, a randomised observation period (Day 1 through Week 6) and, for subjects experiencing a suspected DHS and a subset of DDS-tolerant subjects, an epicutaneous patch test (EPT) assessment period. Eligible subjects will be randomised to one of two study arms: a Current Standard of Care Arm (no prospective genetic screening: Control) and a Genetic Screening Arm (prospective genetic screening: Case). Subjects identified as HLA-B*1301 positive in the prospective Genetic Screening Arm will not receive dapsone and will be excluded from further study. Subjects who experience suspected DHS during the 6-week observation would be withdrawn from dapsone and undergo EPT patch testing 6 weeks later.
We are recruiting for a chronic hives study. This research is being done to test whether an investigational drug called AZD1981 may be helpful for treating people with Chronic Idiopathic Urticaria who continue to have symptoms despite taking antihistamines. The word "investigational" means that AZD1981 is not approved for marketing by the Food and Drug Administration (FDA). The FDA is allowing the use of AZD1981 in this study. People with chronic hives lasting for at least 6 months and without a known cause may join. The study involves 6 visits over 8 weeks. Approximately 48 participants expected to take part in this study at the Johns Hopkins Asthma and Allergy Clinic. All participants will be treated with the study medication and/or placebo for 8 weeks. The results of this trial may have a benefit others with Chronic Idiopathic Urticaria who don't respond well to antihistamines by generating experience and data to support the design of a larger, multicenter trial investigating the efficacy of AZD1981 in treating antihistamine refractory CIU.
This study investigates the genetic architecture of Neutrophil-Mediated Inflammatory Skin Diseases. After collecting informed consent, all patients' clinical phenotype is graded at inclusion with a detailed case report form and a discovery cohort formed based on the certainty of diagnosis. The DNA of patients in the discovery cohort is analyzed by whole exome sequencing which identifies all protein-coding genetic variants. Subsequently, statistical burden tests are going to identify enrichment of rare coding genetic variants in patients affected by Neutrophil-Mediated Inflammatory Skin Diseases. The ultimate goal is to reveal the responsible gene(s) that may then be targets for clinical intervention.
The aim of this study is to assess the influence of kind of allergic disease, allergic profile, allergen exposure, treatment method on lung function parameters, fractional exhaled nitric oxide level in children suspected and being diagnosed due to allergic diseases.
Evaluation whether canakinumab leads to improvement of urticaria
Chronic idiopathic urticaria (CIU) is a common form of chronic urticaria in which the cause is not detected after intensive clinical and laboratory investigation.In view of the current data, it was suggested that at least part of the patients with CIU have an autoimmune process.This study is designed to investigate the mechanisms involved in the regulation and activation of the immune cells in patients with CIU and corelate them with disease activity
