An abnormal diurnal variation in arginine vasopressin secretion is highly prevalent in nocturnal polyuria. Moreover, it is relevant to mean blood pressure or sympathetic tone, such that the effects of nonosmotic control seem clinically implicated. Particular emphasis has been applied to the importance of considering comprehensive assessments not only of arginine vasopressin secretion function, but also of the possible underlying cardiovascular condition or hypertension in the treatment modality of nocturnal polyuria.
BackgroundAtopic dermatitis is the first clinical manifestation of the atopic march, with the highest incidence in the first year of life. Those affected often go on to develop other allergic diseases including food allergy, asthma, and allergic rhinitis. Recent evidence suggests that sensitization to foods may occur through a defective skin barrier which is common in atopic dermatitis in early life. We hypothesize that therapeutic aggressive intervention to treat new onset atopic dermatitis may prevent the development of later allergen sensitization, and associated food allergy, asthma, and allergic rhinitis.MethodsThis study is a multi-center, pragmatic, two-parallel group, assessor-blind, superiority, individually randomized controlled trial. Atopic dermatitis infants (N = 650) 7–13 weeks old who develop an itchy rash within the previous 28 days are randomly assigned to the aggressive treatment or the conventional treatment in a 1:1 ratio. The primary outcome is oral food challenge-proven IgE-mediated hen’s egg allergy at the age of 28 weeks.DiscussionThis is a novel pragmatic RCT study to examine the efficacy of early aggressive treatment for atopic dermatitis to prevent later food allergy. If our hypothesis is correct, we hope that such a strategy might impact on disease prevention in countries where food allergy is common, and that our results might reduce the frequency and associated costs of all food allergies as well as hens egg food allergy. Long-term follow and other similar studies will help to determine whether such a strategy will reduce the burden of other allergic diseases such as asthma and allergic rhinitis.Trial registration UMIN-CTR: UMIN000028043Electronic supplementary materialThe online version of this article (10.1186/s13601-018-0233-8) contains supplementary material, which is available to authorized users.
