Progressive outer retinal necrosis in immunocompromised kidney allograft recipient

Area of Science:

• Ophthalmology
• Virology
• Transplantation Immunology

Background:

• Ocular complications post-renal transplant are often linked to immunosuppression.
• Progressive outer retinal necrosis (PORN) syndrome is a severe necrotizing retinopathy primarily affecting individuals with acquired immunodeficiency syndrome (AIDS).

Observation:

• A case study of a human immunodeficiency virus-negative patient who received a renal transplant.
• The patient later developed bilateral PORN syndrome.
• Viral infections, specifically Varicella zoster virus (VZV) and BK virus, were identified in the patient's vitreous fluid.

Findings:

• The presence of VZV and BK virus in a non-HIV transplant patient with PORN syndrome.
• Uncertainty regarding the specific role or synergistic action of VZV and BK virus in causing PORN and other organ damage.

Implications:

• This case expands the known clinical spectrum of PORN syndrome beyond HIV/AIDS patients.
• Highlights the importance of vigilant immune surveillance in transplant recipients.
• Suggests pre-transplant vaccination against VZV may be crucial in preventing such complications.
