Brief Summary

The investigators are conducting a prospective study to determine the safety and outcomes of placebo-controlled graded drug challenges without prior skin testing in patients with a low-risk history of antibiotic hypersensitivity reaction based on history alone. The investigators hypothesize that the rate of reaction to graded drug challenges without prior skin testing in patients with a low-risk history of drug hypersensitivity reaction based on history alone will not be meaningfully more than the rate of reaction to placebo. The investigators hypothesize that the rate of adverse reactions to drug challenges without prior skin testing will not be meaningfully more than the rate of adverse reactions with prior skin testing as was observed in the investigators' historical clinic cohort.

Outcome Measures

Primary Outcomes (1)

  • Rate of unexpected reaction to graded drug challenges without prior skin testing compared to rate of unexpected reaction to graded drug challenges with prior skin testing.

    Determine the rate of unexpected reaction to a graded drug challenge without prior skin testing versus the rate of reaction to a graded drug challenge with prior skin testing in the investigators' historical cohort (data on this cohort has already been published: Iammatteo M, Ferastraoaru D, Koransky R, Alvarez-Arango S, Thota N, Akenroye A, Jerschow E. Identifying Allergic Drug Reactions Through Placebo-Controlled Graded Challenges. J Allergy Clin Immunol Pract. 2017 May - Jun;5(3):711-717.e2.).

    It is anticipated the study will take 2 years to enroll 200 patients with subsequent data comparison.

Secondary Outcomes (2)

  • Rate of unexpected reaction to graded drug challenges versus placebos

    Patients are monitored for 1 hour after completion of their drug challenge.

  • Rate of unexpected delayed reaction to graded drug challenges

    Patients are called within 1 month of their challenge to determine if they had any delayed reactions.

Study Arms (1)

Placebo-Controlled Graded Drug Challenge

OTHER

This is a single arm study. All patients will receive a placebo prior to a graded drug challenge. Each patient serves as his/her own control.

Drug: Placebo-Controlled Graded Drug Challenge

Interventions

All patients receive a placebo followed by 30 minutes of observation. Patients then receive 1/10 of the treatment dose of the challenge drug followed by 30 minutes of observation. If no reaction, they will then receive a full dose of their challenge drug followed by 1 hour of observation. If they do not experience any reactions, they are deemed not to be allergic. All patients are asked to monitor for delayed reactions after the challenge. Patients are also called within 1 month of the challenge to determine if any delayed reactions occurred. Patients are called again within 1 year of the challenge to determine if they have subsequently taken the challenge drug and experienced any reactions.

Eligibility Criteria

Age7 Years+
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • All patients seven years of age or older who have a low-risk, non-life-threatening history of adverse reaction to an antibiotic.

You may not qualify if:

  • Patients under the age of seven.
  • Pregnant patients.
  • Patients with a history of a drug reaction that is high-risk and life-threatening including life-threatening angioedema, bronchospasm, or anaphylactic shock or a history of severe non-IgE-mediated reactions including serum sickness, Stevens-Johnson syndrome, toxic epidermal necrolysis, interstitial nephritis, hepatitis, hemolytic anemia, DRESS, skin and/or oral blisters, hypersensitivity vasculitis, pneumonitis, or pulmonary fibrosis.
  • Patients who have taken antihistamines within 3 days of the drug challenge.
