Cytomegalovirus implicated in a case of progressive outer retinal necrosis (PORN)
1University of Miami Miller School of Medicine/Jackson Memorial Hospital, Miami, FL 33136, USA.
Abstract:
Progressive outer retinal necrosis, also known as PORN, has been described as a variant of necrotizing herpetic retinopathy, occurring particularly in patients with acquired immune deficiency syndrome (AIDS). Although the etiologic organism has been reported to be Varicella-zoster virus, cytomegalovirus (CMV) can be an etiologic agent. Our case illustrates the occurrence of two opportunistic infections: PORN associated with CMV and Mycobacterium avium intracellulare duodenitis in a patient with uncontrolled HIV infection.
Insights
Progressive outer retinal necrosis (PORN), a severe eye condition, can be caused by cytomegalovirus (CMV) in patients with acquired immune deficiency syndrome (AIDS). This case highlights CMV-related PORN and Mycobacterium avium intracellulare duodenitis in uncontrolled HIV.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Virology
Background:
- Progressive outer retinal necrosis (PORN) is a necrotizing retinopathy often seen in patients with acquired immune deficiency syndrome (AIDS).
- Varicella-zoster virus is a known cause, but other etiologic agents are possible.
- Opportunistic infections are common in individuals with uncontrolled human immunodeficiency virus (HIV) infection.
Observation:
- A case study of a patient with uncontrolled HIV infection.
- The patient presented with simultaneous opportunistic infections.
- These included PORN and Mycobacterium avium intracellulare duodenitis.
Findings:
- Cytomegalovirus (CMV) was identified as the etiologic agent for PORN in this patient.
- This demonstrates CMV as a cause of PORN, a variant of necrotizing herpetic retinopathy.
- The co-occurrence of CMV-related PORN and Mycobacterium avium intracellulare duodenitis was observed.
Implications:
- Highlights the potential role of CMV in PORN, expanding beyond Varicella-zoster virus.
- Underscores the risk of multiple opportunistic infections in patients with uncontrolled HIV.
- Emphasizes the importance of identifying specific etiologic agents for effective management of PORN and other infections in immunocompromised individuals.
