Abstract:
JC polyomavirus (JCPyV) is a human polyomavirus that can establish lifelong persistent infection in the majority of adults. It is typically asymptomatic in immunocompetent individuals. However, there is a risk of developing progressive multifocal leukoencephalopathy (PML) in immunocompromised or immunosuppressed patients. Though JCPyV commonly resides in the kidney-urinary tract, its involvement in urinary system diseases is extremely rare. Here, we reported a case of a 60-year-old male patient with coronavirus disease 2019 (COVID-19) infection who developed hemorrhagic cystitis after receiving treatment with nirmatrelvir 300 mg/ritonavir 100 mg quaque die (QD). Subsequent metagenomic next-generation sequencing (mNGS) confirmed the infection to be caused by JCPyV type 2. Then, human immunoglobulin (PH4) for intravenous injection at a dose of 25 g QD was administered to the patient. Three days later, the hematuria resolved. This case illustrates that in the setting of compromised host immune function, JCPyV is not limited to causing central nervous system diseases but can also exhibit pathogenicity in the urinary system. Moreover, mNGS technology facilitates rapid diagnosis of infectious etiology by clinical practitioners, contributing to precise treatment for patients.
Insights
JC polyomavirus (JCPyV) can cause urinary tract disease in immunocompromised patients, as seen in a COVID-19 case. Rapid diagnosis via metagenomic sequencing led to effective treatment with immunoglobulin therapy.
Area of Science:
- Virology
- Immunology
- Urology
Background:
- JC polyomavirus (JCPyV) establishes persistent infections, typically asymptomatic in immunocompetent individuals.
- JCPyV is primarily associated with central nervous system diseases like progressive multifocal leukoencephalopathy (PML) in immunosuppressed patients.
- While JCPyV resides in the kidney-urinary tract, its role in urinary system diseases is exceptionally rare.
Observation:
- A 60-year-old male with COVID-19 developed hemorrhagic cystitis after treatment with nirmatrelvir/ritonavir.
- Metagenomic next-generation sequencing (mNGS) identified JCPyV type 2 as the causative agent.
- Intravenous human immunoglobulin (PH4) therapy resulted in the resolution of hematuria within three days.
Findings:
- This case demonstrates JCPyV's potential pathogenicity in the urinary system, beyond its known neurological effects.
- The study highlights the importance of considering JCPyV in urinary tract infections, particularly in immunocompromised hosts.
- Metagenomic next-generation sequencing (mNGS) proved crucial for rapid and accurate diagnosis of the infectious etiology.
Implications:
- The findings suggest that JCPyV should be considered in the differential diagnosis of hemorrhagic cystitis in immunocompromised individuals.
- Rapid diagnostic tools like mNGS can significantly improve patient outcomes by enabling timely and targeted therapies.
- This case expands the understanding of JCPyV's clinical manifestations and the utility of immunoglobulin therapy in managing JCPyV-associated diseases.
