Cytomegalovirus infections of the nervous system in patients with AIDS
1Department of Medicine, UCSD School of Medicine, USA.
Abstract:
Retinitis due to cytomegalovirus (CMV) infection is a widely recognized complication of advanced disease due to human immunodeficiency virus type 1 (HIV-1). Less appreciated are other neurological manifestations of CMV infection in persons with AIDS. Dr. J. Allen McCutchan has comprehensively reviewed the various clinical presentations of CMV neurological disease as well as the methods of diagnosis, the neuropharmacology of available antiviral agents, the results of therapy, and the potential for prevention of these sequela of advanced immunosuppression. As the ability to prevent diseases such as Pneumocystis carinii pneumonia, bacteremia secondary to Mycobacterium avium, tuberculosis, serious fungal infections, and toxoplasma cerebritis is increasing, physicians must now treat more HIV-1-infected persons with CMV disease. This AIDS Commentary provides a timely update of the current state of our knowledge regarding this serious problem.
Insights
Cytomegalovirus (CMV) neurological disease is a serious complication in advanced human immunodeficiency virus (HIV) infection. This review covers CMV neurological disease diagnosis, treatment, and prevention in AIDS patients.
Area of Science:
- Neuroscience
- Infectious Diseases
- Virology
Background:
- Cytomegalovirus (CMV) retinitis is a known complication of advanced human immunodeficiency virus type 1 (HIV-1) infection.
- Other neurological complications of CMV infection in individuals with acquired immunodeficiency syndrome (AIDS) are less recognized.
- Increasing success in preventing other opportunistic infections in HIV-1 patients necessitates greater focus on CMV disease.
Purpose of the Study:
- To provide a comprehensive review of CMV neurological disease in the context of advanced HIV-1 infection.
- To update physicians on the current knowledge of CMV neurological disease, including diagnosis, treatment, and prevention.
- To highlight the growing importance of managing CMV disease as other AIDS-related complications become more preventable.
Main Methods:
- Comprehensive literature review of CMV neurological disease in HIV-1 infected individuals.
- Analysis of clinical presentations, diagnostic methods, and neuropharmacology of antiviral agents.
- Evaluation of therapeutic outcomes and preventive strategies for CMV neurological sequelae.
Main Results:
- CMV can cause various neurological manifestations in individuals with AIDS.
- Effective diagnostic and therapeutic strategies exist for CMV neurological disease.
- Preventive measures are crucial for managing CMV disease in advanced immunosuppression.
Conclusions:
- CMV neurological disease is a significant and often underappreciated complication of advanced HIV-1 infection.
- Physicians must be prepared to diagnose, treat, and prevent CMV neurological disease in the growing population of HIV-1 survivors.
- Further research and clinical attention are needed to fully address the impact of CMV on the central nervous system in AIDS patients.
