The standard treatment for early-stage breast cancer is breast-conserving surgery followed by adjuvant radiation therapy to the whole breast. This approach leads to low recurrence rates with a good cosmesis and provides an effective alternative to mastectomy. However, in most women receiving radiotherapy radiation dermatitis occur to some degree. Radiation dermatitis generally manifests within a few weeks after the start of radiation therapy. Its onset varies depending on the radiation dose intensity and the normal tissue sensitivity of individuals. As the cumulative dose of radiation increases the transient erythema occurring during the first weeks of radiotherapy may evolve into the more persistent erythema and to dry or even moist desquamation that reflects the damage to the basal cell layer and the sweat and sebaceous glands. There is currently no evidence that prophylactic treatments, beyond keeping the irradiated area clean and dry, are effective in reducing the incidence or severity of radiation dermatitis (Bolderston et al. 2006). However, together with other enzymes of the peroxidase pathway, SOD scavenges the superoxide, hydroxyl, and other oxygenated free radicals (Klug et al. 1972; Tainer at al. 1983). In physiological conditions, the production of free radicals (Monte & Sacerdote 1994) and the action of antiradicals' enzymes is balanced. Following tissue injuries, either pathological or caused by agents such as radiation therapy, an excess production of free radicals is observed (Petkau 1986; Lorette & Machet 2001). Furthermore, basal SOD is increased in breast cancer patients before radiation therapy as compared to controls (Seth et al. 2003), and decreases after radiotherapy (Ray at al. 2000). Hence, liposomal rhSOD applied during radiotherapy could be used to prevent the effects of free radicals and thus might protect the patient's skin from radiation-induced skin reactions. TREATMENT PLAN All patients receive APN201 and placebo at the same time. The irradiated region is divided vertically into two symmetric areas (left and right). One area is treated with APN201, the other area is treated with placebo in a double-blind fashion. Study treatment (APN201 and placebo) starts on the day of initiation of radiation therapy and continues until the end of radiation therapy to the whole breast (25 or 28 daily fractions to a total dose of 50.0 Gy or 50.4 Gy, respectively) (see schedule of assessments, section 5.1). Study treatment is stopped if radiation dermatitis of ≥ grade 2 occurs in one or both treated areas for ≥ 3 days AND a difference in the severity of radiation dermatitis of ≥ 1 grade is seen between the two treated areas. From that point in time the patient only receives the treatment that appeared to be beneficial and this treatment is applied to the whole irradiated region until completion of the 25th, respectively 28th, fraction. Treatment stops earlier in case of progressive disease or unacceptable toxicity or intolerability.
Probiotics are suggested to have beneficial effects in atopic dermatitis (AD) treatment and prevention but their precise role is not yet clear. The aim of this randomized double blinded active treatment vs placebo study was to evaluate clinical efficacy of intake of a combination of two probiotics (Lactobacillus salivarius LS01 and Bifidobacterium breve BR03) for the treatment of adult AD patients. The rationale for the use of probiotics in the treatment of atopic dermatitis would be due to some experimental hypotheses: 1. The use of these microbial agents at an early age seems to play an important role in inducing immunity T type 1 (Th1) and inhibit the development of a Th2 response IgE mediated 2. the normal intestinal flora (including probiotics) would play an important role in inducing immunological tolerance 3. the hygiene hypothesis that the reduced bacterial environment would favour a type 2 response T and the development of allergic diseases
The purpose of this study is to evaluate the safety, tolerability, and efficacy of JNJ-39758979 in adult Japanese patients with moderate, active atopic dermatitis.
The purpose of this multi-center, clinical registry study is to determine genetic markers associated with susceptibility of AD patients to infections and to also serve as a potential participant database for future studies.
The purpose of this study is to analyze the expression and activity of inhibitory molecules on eosinophils obtained from allergic subjects.
Hand eczema is a common disease which often gives a chronic course thus affecting many functions in daily life. The body of evidence related to self-management of chronic hand eczema is poor. Better methods to support self-management of patients with chronic hand eczema may potentially improve the prognosis of a disease which is both a tremendous burden to the individual and to the society. The purpose of this trial is to evaluate the effect of a newly designed guidance programme offering individual counselling compared to conventional information with written information sheets.
Radiodermatitis and radiation mucositis were the most frequent side-effect during the course of radiotherapy, especially when concurrent chemoradiotherapy applied. Since reactive oxygen species formed upon radiation therapy play a central role in initiating and driving the detrimental signaling events, antioxidant supplementation is thought to provide a photoprotective effect against radiation. Green tea extract has been shown to have antioxidant and anti-inflammatory effects on various types of cells. To evaluate the safety and efficiency of green tea extract in the treatment of radio dermatitis and radiation mucositis, the investigators conducted this phase Ⅰ,II study using topical EGCG in cancer patients receiving radiotherapy or concurrent chemoradiotherapy .
This is a mono-center, randomized, double-blind, placebo-controlled, parallel-group study to assess the effect of challenges with dactylis glomerata pollen in an environmental challenge chamber on dermal symptoms in patients suffering from atopic dermatitis. After each challenge session and on Day 3, Day 4, and Day 5 blood samples will be taken for biomarker assessments. The severity of atopic dermatitis will be rated with the "SCORing Atopic Dermatitis" (SCORAD), with the objective SCORAD and with the assessment of itch and sleeplessness referring to the past 24 hours by a blinded observer (trained dermatologist) on each day including baseline assessments.
Although some causal factors in allergy development such as allergen exposure and environmental pollution have decreased during recent years, the incidence of the allergic diseases has increased in the Western world. Since the genetic predisposition to develop allergies cannot change in such a short time it is conceivable that, instead of the emerging of some new and unknown risk factors, some protective factors seem to have disappeared in the Western world. Allergic disease is a tendency to develop allergies to allergens in the surrounding environment. The most common symptoms are eczema and food allergy in the early life, bronchial asthma (AB) later in childhood and allergic rhino conjunctivitis (ARC) during school age and adolescence, the so-called allergic march. Some person may develop only one, but others some or all of the symptoms. Inheritance, environment and allergen exposure are important factors affecting this march but there are important factors that predict later development of diseases. Sensitization to egg (positive skin prick test or specific IgE to egg in the serum) combined with skin problems in infancy predispose strongly to the development of allergic asthma in later life. The purpose of this work is to supply children with early development of IgE associated eczema and food allergy with omega-3 LCPUFA before the age of 12 months and assess the effect of the supplementation on the future development of skin symptoms, food allergy, sensitisation against inhalant allergens and asthma in these children. We will also assess immunological markers of Th2-skewed immunity in relation to clinical effect of the supplementation. Families with children younger than 12 months referred to the paediatric department at Linköping University Hospital, Motala, Norrköping and Jönköping Hospitals in the South East of Sweden, with the diagnosis IgE associated eczema and sensitised against food allergens (egg, milk, wheat and/or soya) will be invited to participate in this study. Clinical examination by a paediatrician and assessment of disease severity with SCORAD will be performed by a research nurse at inclusion. The children will be assessed every six months by a nurse until 2.5 years of age and by a paediatrician at 3 years of age. Later clinical assessment will be performed yearly until age 7.
