Abstract
- Background The Centers for Disease Control and Prevention recommends that all patients be tested for HIV while in a healthcare setting. HIV testing is especially important in patients with a central nervous system (CNS) infection because it impacts the differential diagnosis. In this study, we determined the rate of HIV testing in patients who presented with a CNS infection. Methods We performed a multicenter retrospective study of 1,312 patients over the age of 17 years with community or healthcare-acquired meningitis, aseptic meningitis or encephalitis admitted to 18 hospitals in New Orleans, LA and Houston, TX from July 1, 1998 through December 31, 2017. Prospective patients were identified using ICD 9 coding, physical examination findings, and cerebrospinal fluid analysis. The electronic medical records for these patients were reviewed for HIV testing and diagnosis. Aseptic meningitis cases were also reviewed for HIV RNA PCR testing. 100 patients with a known HIV diagnosis were excluded (2 aseptic meningitis, 82 encephalitis, and 16 community-acquired meningitis). Results Out of 1,312 patients presenting with a confirmed CNS infection, 664 (50.6%) had an HIV test done. A total of 81 patients (12.2%) were newly diagnosed with HIV during admission. Patients who underwent HIV testing were more likely to be non-caucasian, have no underlying comorbidities, lower Glasgow coma scale, and more seizures on presentation (P < 0.05). HIV testing also varied by type of CNS infection: community-acquired meningitis (98/142, 69.0%); encephalitis (180/261, 69.0%), aseptic meningitis (300/643, 46.6%), and healthcare-associated meningitis (86/289, 29.7%). In only 35 out of 547 patients (6.4%) presenting with acute aseptic meningitis was an HIV RNA PCR test ordered; 26 out of the 35 (74%) HIV RNA PCRs were positive with 9 patients being diagnosed with acute HIV seroconversion syndrome. Conclusion HIV testing is done in only one-half of patients with CNS infections with only a minority of patients presenting with acute aseptic meningitis being evaluated for acute HIV seroconversion syndrome. Clinicians should order an HIV test on all patients with CNS infections and consider testing for HIV RNA PCR in patients presenting with acute aseptic meningitis especially in those where the etiologic diagnosis remains unknown.
