Long-Term Survival, Morbidity, Social Functioning and Risk of Disability in Patients with a Herpes Simplex Virus Type 1 or Type 2 Central Nervous System Infection, Denmark, 2000–2016
Open accessAbstract
BACKGROUND: The long-term prognosis following herpes simplex virus (HSV) central nervous system (CNS) infection is still debated. PATIENTS AND METHODS: We examined outcomes in all Danish residents who, during 2000-2016, tested PCR positive for HSV-1 (n=208) or HSV-2 (n=283) in the cerebrospinal fluid, compared to comparison cohorts from the general population (n=2080 and n=2830). RESULTS: One-year mortality was increased among HSV-1 patients (difference 19.3%; 95% CI: 13.6% to 25.0%) and HSV-2 patients (difference 5.3%; 95% CI: 2.5% to 8.1%), but thereafter mortality was not increased. After exclusion of persons diagnosed with cancer prior to study inclusion, one-year mortality difference for HSV-2 patients was 1.7% (-0.1% to 3.5%). After five years, HSV-1 patients had lower employment (difference -19.8%; 95% CI: -34.7% to -4.8%) and higher disability pension rates (difference 22.2%; 95% CI: 8.4% to 36.0%) than the comparison cohort, but similar number of inpatient days, outpatient visits, and sick leave. HSV-2 patients had employment and disability pension rates comparable to the comparison cohort, but more inpatient days (difference 1.5/year; 95% CI: -0.2 to 3.2), outpatient visits (difference 1.3/year; 95% CI: 0.3 to 3.2), and sick leave days (difference 9.1/year; 95% CI: 7.9 to 10.4). CONCLUSION: HSV-1 and HSV-2 CNS infections differ substantially with respect to prognosis. HSV-1 CNS infection is followed by increased short-term mortality and long-term risk of disability. HSV-2 CNS infection has no substantial impact on mortality or working capability but is associated with increased morbidity.

Short-term outcome after viral meningitis was frequently unfavourable but improved during extended follow up.
“In agreement with most previous studies, we observed that short-term outcome after viral meningitis was frequently unfavourable but improved during extended follow up.6,21,22”

The Discussion (page not provided) says HSV-2 CNS infection, which mainly presents as meningitis, may cause short-term neurological morbidity but generally has a benign long-term prognosis. It does not establish that short-term outcomes were frequently unfavourable, demonstrate improvement in individual patients over follow-up, or extend the finding to viral meningitis generally.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
