CMV Retinitis in the Context of SARS-CoV-2 Infection: A Case Study and Comprehensive Review of Viral Interactions. Pathogens 2024; 13:938. [PMID: 39599491 PMCID: PMC11597558 DOI: 10.3390/pathogens13110938] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2024] [Revised: 10/23/2024] [Accepted: 10/25/2024] [Indexed: 11/29/2024] Open
Abstract
PURPOSE Cytomegalovirus (CMV) retinitis is a sight-threatening condition predominantly affecting immunocompromised individuals, such as those with Human Immunodeficiency Virus (HIV)/Acquired Immunodeficiency Syndrome (AIDS). We aimed to present an observational case report on CMV retinitis following Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection and to review the literature on the molecular and cellular changes in CMV and SARS-CoV-2 infections and how they may influence each other. Case Description: A 32-year-old man with a history of AIDS presented with decreased vision and ocular pain exacerbated by movement, beginning a day prior. Ocular examination revealed anterior uveitis, corneal endothelial edema, and retinal necrosis in the left eye. CMV retinitis was diagnosed based on positive serologic testing and a low cluster of differentiation 4 (CD4) count, with concurrent SARS-CoV-2 infection detected. Treatment included valganciclovir and topical agents, with a focus on managing CMV complications. This case highlights the potential role of SARS-CoV-2 in reactivating dormant CMV in severely immunocompromised individuals. We also discuss the implications of this interaction for immunocompromised patients, emphasizing the need for vigilant monitoring and personalized treatment strategies. Conclusions: Our case suggests that SARS-CoV-2 may trigger reactivation of CMV infection, leading to bilateral involvement in patients with low CD4 lymphocyte counts, which can result in severe visual impairment. The review discusses the molecular and cellular interactions between CMV and SARS-CoV-2, as well as risk factors, pathophysiology, and diagnostic methods for CMV retinitis, providing recommendations based on the literature findings.

Abstract
PURPOSE OF REVIEW Occlusive retinal vasculitis (ORV) has a large differential diagnosis and varied therapeutic approaches. This review highlights existing and novel causes and treatment options for ORV. RECENT FINDINGS Mutations in CAPN5, TREX1, and TNFAIP3 have been associated with dominantly inherited forms of ORV. Various intraocular therapeutics have been shown to occasionally cause ORV; the most recent medications associated with ORV are vancomycin and brolucizumab. In cases of ORV linked to Behçet's disease, clinical trials support the use of tumor necrosis factor alpha inhibitors. SUMMARY Identification of the underlying etiology of ORV is critical to help guide treatment. Treatment in ORV involves both treatment any underlying infection or autoimmune condition, cessation of the any offending causative agent and local treatment of neovascular complications.
