Comparative Study
Pholcodine stimulates a dramatic increase of IgE in IgE-sensitized individuals. A pilot study.
A previous study showed a relation between pholcodine (PHO) consumption, prevalence of IgE-sensitization to PHO, morphine (MOR) and suxamethonium (SUX) and anaphylaxis to neuromuscular blocking agents (NMBA). The purpose of this pilot study was to explore the effect on IgE production, in IgE-sensitized and nonsensitized individuals, of exposure to cough syrup and environmental chemicals containing PHO, MOR and SUX related allergenic structures. ⋯ It seems as cough syrups containing PHO have a most remarkable IgE boostering effect in persons IgE-sensitized to PHO, MOR and SUX related allergens. Household chemicals containing such allergenic epitopes seem capable of some, minor, stimulation.

Randomized Controlled Trial Multicenter Study Comparative Study
Comparison of roflumilast, an oral anti-inflammatory, with beclomethasone dipropionate in the treatment of persistent asthma.
Roflumilast is an oral, once-daily phosphodiesterase 4 inhibitor with anti-inflammatory activity in development for the treatment of asthma. Roflumilast was compared with inhaled beclomethasone dipropionate (BDP) in patients with asthma. ⋯ Once daily, oral roflumilast 500 microg was comparable with inhaled twice-daily BDP (400 microg/day) in improving pulmonary function and asthma symptoms, and reducing rescue medication use in patients with asthma.

Comparative Study
Sensitization to blackgram in patients with bronchial asthma and rhinitis: clinical evaluation and characterization of allergens.
Legumes are important causative agents of type I hypersensitivity in south Asia and Europe but such studies are lacking in Indian population. The present study investigates blackgram sensitization in asthma and rhinitis patients and identifies immunoglobulin E (IgE)-binding proteins. ⋯ Blackgram induces IgE-mediated reactions in 1.7% of asthma and rhinitis patients and contains eight major IgE-binding components, of which six retained IgE reactivity after roasting. Blackgram shares allergenicity with lentil and limabean.
