55 participants

Abstract

This is a randomized, double-blind, placebo-controlled, crossover study comparing asthma control post treatment in African American/Black and Caucasian/White children in both hyper and hypo responsive HILD (Histamine Lontophoresis with Laser Doppler monitoring) phenotypes with uncontrolled persistent allergic asthma using Levocetirizine (LTZ) vs placebo.

Conditions: Allergic Asthma.

Primary outcome: Therapeutic response to antihistamine.

Enrollment: 55 participants.

How strong is the evidence?
