Abstract

The existence of a restrained inflammatory state in schizophrenic individuals posed the question whether anti-inflammatory drugs may exert antipsychotic effects. Therefore, the effect of ibuprofen (IB) on cytokine production by human peripheral blood mononuclear cells (PBMC) from schizophrenic patients was examined and compared to that of healthy subjects. PBMC from 25 schizophrenic patients and 24 healthy volunteers were incubated for 24 h with lipopolysaccharide (LPS) in the absence or presence of various concentrations of IB. The levels of IL-1β, IL-6, TNF-α, IL-10 and IL-1ra in the supernatants were tested applying ELISA kits. The secretion of TNF-α by cells from schizophrenic patients was significantly lower compared with controls. IB caused stimulation of TNF-α and IL-6 production by cells of the two groups and enhanced IL-1β secretion by cells from schizophrenic patients. IB inhibited IL-1ra and IL-10 generation by cells from the two groups. Without IB, IL-1ra secretion was negatively correlated with the disease severity, while 200 μg/ml of IB positively correlated with the PANSS total score. IL-10 production was positively correlated with the PANSS positive subscale score both in the absence or presence of IB. The findings suggest that the effect of IB on the production of inflammatory cytokines may benefit the health of schizophrenic patients.
