Abstract

OBJECTIVE: Bipolar disorder (BD) has been associated with persistent low-grade inflammation and premature cell senescence, as shown by reduced telomere length (TL). The human cytomegalovirus (CMV) has increasingly been implicated in accelerated immunosenescence in aging studies. Here, we compared CMV serology and its relationships with cell senescence markers, including TL and lymphocyte subsets, in patients with type I BD and healthy controls. METHODS: Twenty-two euthymic female patients with BD type I and 17 age-matched healthy controls were selected for the study. A sample of blood was collected and mononuclear cells and DNA were isolated and TL measured. CMV immunoglobulin M (IgM) and IgG titers were measured using chemiluminescent assays. Lymphocyte subsets [T, natural killer (NK) and NKT] were phenotyped by flow cytometry. RESULTS: Individuals with BD had shorter TLs but higher CMV IgG levels than controls (both p < 0.01). CMV IgG level was inversely correlated with TL. None of the subjects showed IgM reactivity for CMV, excluding acute viral infection. CMV IgG level was associated with expansion of senescent CD8+CD28- T cells and NK cells, which are involved in viral control. CONCLUSIONS: These data support the hypothesis of accelerated aging in BD, as shown by shortened telomeres, higher seropositivity for CMV, and expansion of senescent T cells.

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.
