A structure-activity relationship (QSAR) analysis of 19 thiazole derivatives with H1-antihistamine activity was carried out. The semi-empirical method AMI was employed to calculate a set of physicochemical parameters for investigated compounds. The principal component analysis (PCA), discriminant function analysis (DFA) and regression analysis (RA) were employed to reduce dimensionality and inv...

There is a lack of large, randomized, double-blind studies that address antihistamine updosing for chronic spontaneous urticaria (CSU). The objective of this systematic review is to explore and analyse available data to provide clinical evidence for the efficacy of antihistamine updosing.

The treatment of antihistamine and steroid resistant Chronic Idiopathic Urticaria (CIU) during pregnancy poses a challenge due to teratogenicity of immunosuppressants. Omalizumab is a recently FDA approved therapy for CIU and is classified as pregnancy category B. We present an initial series of subjects treated at a tertiary care center for antihistamine and steroid resistant CIU with omalizum...

BACKGROUND Allergies have been associated with decreased risk of glioma; but, associations between duration and timing of allergies, and antihistamine use and glioma risk have been less consistent. The objective was to investigate this association by analyzing types, number, years since diagnosis, and age at diagnosis of allergies, and information on antihistamine usage, including type, duratio...
