Sodium nitroprusside as an adjunctive treatment for schizophrenia reduces the Ndel1 oligopeptidase activity.
Objective: Schizophrenia (SCZ) is a disabling disorder that continues to defy clinicians and researchers. We investigated the effects of sodium nitroprusside (sNP) in an animal model of SCZ and as an add-on therapy in patients and the relationship between treatment with sNP and activity of the nDel1 enzyme, whose involvement in the pathophysiology of the disorder has been suggested earlier.
Methods: Ndel1 activity was measured following sNP infusions in spontaneously hypertensive rats (SHR; 2.5 or 5.0 mg/kg) and in a double-blind trial with SCZ patients (0.5 μg/kg/min).
Results: Ndel1 activity was significantly reduced after sNP infusion in blood of SHR compared to controls, and in patients receiving sNP (t = 7.756, df = 97, p < 0.0001, dcohen = 1.44) compared to placebo. Reduced Ndel1 activity between baseline and the end of the infusion was only seen in patients after treatment with sNP.
Conclusion: Our findings suggest that SCZ patients may benefit from adjunctive therapy with sNP and that the Ndel1 enzyme is a candidate biomarker of psychopathology in the disorder. Future research should look into the role of Ndel1 in SCZ and the potential effects of sNP and drugs with similar profiles of action in both animals and patients.
