|October 1, 1978
Summary
Corneal transplants using penicillin G-preserved donor corneas are safe for patients with penicillin allergy. This study found no increased risk of complications or graft failure in allergic recipients, indicating penicillin allergy does not impact transplant outcomes.
Area of Science:
- Ophthalmology
- Transplantation Immunology
- Allergy and Immunology
Background:
- Corneal transplantation is a common procedure to restore vision.
- Donor cornea preservation media often contain antibiotics, including penicillin G.
- Patients with a history of penicillin allergy may pose a challenge for organ transplantation due to potential hypersensitivity reactions.
Purpose of the Study:
- To evaluate the safety and efficacy of corneal transplantation in recipients with a history of penicillin allergy.
- To determine if donor corneas preserved in McCarey-Kaufman medium containing penicillin G pose a risk to allergic recipients.
Main Methods:
- Retrospective analysis of 34 corneal transplants performed on 32 recipients with a documented penicillin allergy.
- Donor corneas were preserved in McCarey-Kaufman medium supplemented with 100 units/ml of penicillin G.
- Postoperative outcomes, including ocular and systemic complications, graft clarity, and graft survival, were monitored long-term.
Main Results:
- No ocular or systemic postoperative complications were attributed to the penicillin allergy history in any recipient.
- Thirty-two out of 34 corneal grafts remained clear during long-term follow-up.
- Penicillin allergy did not appear to influence the success or failure rate of the corneal grafts.
Conclusions:
- Corneal transplantation using donor corneas preserved with penicillin G is a safe procedure for patients with a history of penicillin allergy.
- The presence of penicillin in the preservation medium does not seem to increase the risk of adverse events or affect graft outcomes in sensitized individuals.
- Clinicians can proceed with corneal transplantation in penicillin-allergic patients without increased concern regarding the use of standard penicillin-containing preservation media.
