Abstract:
Objective:To investigate the efficacy, safety and possible mechanisms of celecoxib as an adjunctive treatment for schizophrenia.Methods:90 schizophrenic inpatients at the second affiliated hospital of Xinxiang Medical College from April 2019 to October 2020 were recruited and randomly assigned to a placebo group or the celecoxib adjunctive treatment group using a random number table. In the placebo group, 46 patients (29 males, 17 females; aged 21-34, mean age 27.46±6.50 years) completed a 6-week follow-up. In the celecoxib group, 44 patients (32 males, 12 females; aged 21-39, mean age 30.52±8.69 years) completed a 6-week follow-up. The Positive and Negative Syndrome Scale (PANSS) was used to assess psychiatric symptoms in both groups. Changes in PANSS score at the end of the treatment were compared to evaluate the efficacy of celecoxib. Metabolic indicators such as weight, body mass index, waist circumference and plasm glucolipid, as well as cardiovascular indicators like blood pressure, electrocardiogram and routine blood tests, and adverse events were collected for the safety evaluation. Serum tumor necrosis factor-α (TNF-α), Interleukin-4 (IL-4) and interferon-γ (IFN-γ) were also tested. Pearson correlation analysis was used to explore the relationship between cytokine levels, PANSS score, PANSS reduction rate [(pre-treatment score-post-treatment score)/pre-treatment score×100%], and the safety measurements in the two groups, analyzing the role of inflammation in celecoxib adjunctive therapy.Results:The change of PANSS positive score at the end of the 6th week was significantly higher in the celecoxib adjuvant treatment group than in the placebo group (-8.00±6.12 vs -4.78±5.19, H=-0.55, P=0.009). The weight changes, body mass index, total cholesterol, and triglycerides over 6 weeks were significantly lower in the celecoxib group compared to the placebo group ( F=-7.37, -7.30, 2.56, -2.54; all P<0.05). No serious adverse events were found in celecoxib adjuvant therapy. In the placebo group, baseline TNF-α levels were positively correlated with baseline negative symptoms and PANSS reduction rate ( r=0.260 and 0.330, both P<0.05), and negatively correlated with the 6-week weight ( r=-0.311, P<0.05); baseline IL-4 levels were positively correlated with the 6-week PANSS total score and the 6-week PANSS negative score ( r=0.320 and 0.397, both P<0.05), and negatively correlated with PANSS reduction rate and 6-week blood glucose ( r=-0.316 and -0.331, both P<0.05); Six-week IFN-γ levels were negatively correlated with low-density lipoprotein levels ( r=-0.306, P<0.05). And no such correlation was found in celecoxib adjuvant group. Conclusion:Celecoxib adjunctive therapy can improve positive symptoms of schizophrenia without causing adverse reactions. Inflammatory state is related to schizophrenia symptoms, treatment efficacy and metabolic abnormalities.
