Objective: To investigate pathological conditions that act as sources of pro-inflammatory cytokines and cytotoxic substances to examine TL in patients with either early (DI ≤ 5 years) or chronic (DI > 5 years) psychosis using T lymphocytes. Methods: Based on these factors and the important role that T lymphocytes play in inflammation, the present study measured the TL of T lymphocytes in patients with either early or chronic psychosis. Additionally, smoking, metabolic syndrome, depression, and cognitive functioning were assessed to control for confounding effects. Results: TL was significantly longer in patients with early and chronic psychosis than in healthy control subjects and, moreover, the significance of these findings remained after controlling for various confounding factors.
Conclusion: Possible mechanisms underlying the effects of antipsychotic medications on telomerase are discussed in the present study, but further studies measuring both telomerase activity and TL using a prospective design will be required.
