Summary

This is a single-center prospective single arm study. The purpose of this study is to assess the usefulness of skin test as a diagnostic tool to predict the hypersensitivity to rituximab in Chinese population, evaluate the rate of hypersensitivity reactions (HSRs) after the application of active desensitization therapy in the case of a positive skin test result, and investigate the mechanism of HSRs to rituximab.

Conditions

  • Drug Hypersensitivity Reaction

Interventions

DIAGNOSTIC_TEST

skin test

For skin prick tests (SPT), rituximab solution of 1mg/ml was applied on the volar aspect of the forearm. For intradermal tests (IDT), 0.02 mL of a 1:100 dilution (0.1mg/ml) of full-strength solution (10mg/ml) was injected first. If the result was negative, a 1:10 dilution（1mg/ml）was then used. As to the desensitization protocol, three solutions with different concentrations are delivered in 12 consecutive steps, each step increasing the rate of drug administration by 2- to 2.5-fold. Solution 1 is a 100-fold dilution (0.01mg/ml) of the final target concentration, solution 2 is a 10-fold dilution (0.1mg/ml) of the final target concentration, and the concentration of solution 3 is the target concentration (1mg/ml). Each step takes 15 minutes until the target rate of 200ml/h is reached, and the final step is prolonged to complete the target dose. The whole procedure takes about 5.5 hours.
