A Component-resolved Diagnostic Approach for a Study on Grass Pollen Allergens in Chinese Southerners with Allergic Rhinitis and/or Asthma
Published on: June 4, 2017
Abstract:
A double-blind clinical trial was undertaken to evaluate the efficacy of orally given cromolyn sodium vs that of pacebo in the management of food allergy. Fourteen children, aged 2 to 15 years, with milk allergy and concomitant allergies to one or more foods were given cromolyn or placebo. Eleven had positive intradermal skin reactions or coproantibodies to offending antigens. Treatment was begun while the children were receiving elimination diets; they were challenged with specific antigen only after 48 hours of drug administration. Crossover took place if the initial agent was ineffective. Cromolyn afforded protection in 11 of 13 trials, whereas placebo was effective in only three of nine trials. By chi 2 analysis, the drug's effect was statistically significant.

Antiasthma Drugs: Methylxanthines
Theophylline is thought to inhibit phosphodiesterase enzymes, increasing intracellular levels of cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP). This rise in cAMP and cGMP concentrations stimulates cardiac function,...

Antiasthma Drugs: Muscarinic Receptor Antagonists
Antimuscarinic agents compete with ACh for the same binding site on the muscarinic receptors. By binding to these receptors, they inhibit the downstream effects of ACh and block the parasympathetic...
Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids
ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...
Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
