Abstract:
Increasing pressure to cut the length of hospital stay has resulted in a large number of patients receiving home parenteral antibiotic therapy. We present a case of an immediate allergic reaction in a penicillin-sensitive spouse of a patient receiving parenteral mezlocillin sodium therapy. A seminal level of 42 micrograms/mL of mezlocillin was documented by bioassay.
Insights
Home parenteral antibiotic therapy is increasing. A penicillin-allergic spouse experienced an immediate allergic reaction to mezlocillin, highlighting potential risks of antibiotic exposure in household contacts.
Area of Science:
- Allergy and Immunology
- Pharmacology
- Infectious Diseases
Background:
- Hospital stay length is decreasing, leading to more home parenteral antibiotic therapy.
- Parenteral antibiotics administered at home pose potential risks to non-patient household members.
- Penicillin allergy is a common concern in clinical practice.
Observation:
- An immediate allergic reaction occurred in a spouse sensitive to penicillin.
- The patient was receiving parenteral mezlocillin sodium therapy at home.
- The spouse had no direct exposure to the antibiotic medication.
Findings:
- A significant level of mezlocillin (42 micrograms/mL) was detected in the spouse via bioassay.
- This finding suggests passive transfer or environmental exposure to the antibiotic.
- The allergic reaction was directly linked to mezlocillin exposure.
Implications:
- Healthcare providers must consider the risk of allergic reactions in household contacts of patients on home parenteral antibiotics.
- Environmental monitoring and patient/family education are crucial to prevent accidental exposures.
- Further research is needed to understand the mechanisms and prevalence of such reactions.
