Q: Question: Is cytomegalovirus coinfection associated with an increased risk of severe non-AIDS-defining events in a large cohort of HIV-infected patients?
Answer: In our study population, CMV/HIV coinfection was associated with the risk of severe non-AIDS-defining events/non-AIDS-related death, especially with cardiovascular and cerebrovascular events, independently of other prognostic factors. This finding supports a potential independent role of CMV coinfection in vascular/degenerative organ disorders in HIV-infected subjects.
