Abstract

Insights

Donor tissue transmitted Candida albicans to a recipient after corneal transplant surgery. Routine donor rim cultures are crucial for preventing fungal keratitis post-keratoplasty.

Area of Science:

  • Ophthalmology
  • Infectious Diseases
  • Microbiology

Background:

  • Corneal transplantation, or penetrating keratoplasty, is a common procedure to restore vision.
  • Fungal keratitis is a serious complication that can lead to vision loss.
  • Donor tissue screening is critical to prevent infectious disease transmission.

Observation:

  • A 15-year-old male developed keratitis and a lenticular abscess 26 days after penetrating keratoplasty.
  • The donor tissue originated from a drowning victim.
  • Candida albicans was identified in both the donor rim and the recipient cornea.

Findings:

  • Antifungal sensitivity and DNA profiles of the isolates from the donor rim and recipient cornea were identical.
  • This confirmed donor-to-host transmission of Candida albicans.
  • The source of the infection was definitively traced to the donor tissue.

Implications:

  • Routine culture of corneal donor rims is essential for early detection of fungal contamination.
  • Close patient follow-up post-keratoplasty is vital, especially when donor rims test positive for fungus.
  • Antifungal prophylaxis may be advisable for patients receiving corneas from donors with positive fungal cultures.

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
Candidiasis01:20

Candidiasis

Candidiasis is a fungal infection caused by opportunistic species of Candida. It can affect various anatomical sites, including the skin, oral cavity, nails, and genitourinary tract. Among its forms, vaginal candidiasis is the most common type of mucosal infection. It typically results from the overgrowth of Candida albicans in the vaginal mucosa. Under normal conditions, C. albicans exists as a commensal organism within the vaginal microbiota, regulated by the dominance of lactobacilli, which...

Bone Marrow Sampling and Transplants

Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy the...

Tissue Transplantation

Tissue transplantation is a significant medical procedure involving the transfer of cells, tissues, or organs from a donor to a recipient, with the primary aim of restoring lost functions. This procedure is crucial in treating a broad spectrum of diseases, including kidney diseases, liver failure, heart disease, and certain types of cancers.

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living donor...
