However, no standardized treatment protocol exists for managing such cases. This study investigates treatment strategies for persistent COVID-19 in immunosuppressed patients by reviewing existing literature and analyzing a clinical case. Materials and Methods: The study focuses on a 48-year-old woman with follicular lymphoma (FL) who experienced multiple COVID-19 episodes despite prior treatments. The patient was treated with a 10-day intravenous remdesivir regimen, oxygen therapy and trimethoprim/sulfamethoxazole prophylaxis while undergoing genomic monitoring. Clinical evaluation included CT scans, chest X-rays, RT-PCR tests and genomic sequencing to track viral mutations. No statistical tests were applied, but the study provides a detailed clinical assessment of disease progression and treatment response. Results: The combination of remdesivir, oxygen therapy and antibiotics successfully improved the patient’s condition, leading to a non-oxygen-dependent SpO₂ of 94% by discharge. Genomic sequencing identified the B.1.177 variant, carrying multiple spike protein mutations, suggesting immune escape mechanisms. Despite an initial negative antigen test after 16 days, the patient remained SARS-CoV-2 positive in subsequent tests, emphasizing the virus’s adaptability in immunosuppressed hosts. The study highlights the importance of genomic monitoring in optimizing treatment strategies. Conclusion: This case study demonstrates the effectiveness of remdesivir, oxygen therapy and antibiotic prophylaxis in treating persistent COVID-19 in immunosuppressed patients. However, the findings are limited by the single-patient analysis, lack of control groups and absence of long-term follow-up. Future research should focus on larger cohorts and randomized controlled trials to evaluate antiviral and immune-modulatory therapies. Genomic surveillance should also be prioritized to understand viral evolution and its impact on treatment outcomes.]]> https://scialert.net/abstract/?doi=aje.2025.1.7 11 June, 2026
