Efficacy of quetiapine fumarate combined with lithium carbonate in the treatment of bipolar disorder in 30 patients / 中国基层医药

ABSTRACT

Objective:To investigate the efficacy of quetiapine fumarate combined with lithium carbonate in the treatment of bipolar disorder and its effect on cognitive function.Methods:Sixty patients with bipolar disorder, who received treatment in Zhuji Fifth People's Hospital from January 2017 to December 2019, were included in this study. They were randomly assigned to receive either lithium carbonate (control group, n = 30) or quetiapine fumarate combined with lithium carbonate treatment (combined treatment group, n = 30). All patients received 4 weeks of treatment. Manic and depressive symptoms pre- and post-treatment, clinical efficacy, cognitive function, and adverse reactions were compared between the two groups. Fasting venous blood was taken before and 4 weeks after treatment to measure superoxide dismutase (SOD), malondialdehyde (MDA), catalase (CAT), and glutathione peroxidase (GSH-Px) levels. Results:The scores of the Bech-Rafaelsdn Mania Rating Scale (BRMS) and the Hamilton Rating Scale for Depression (HAMD) in each group were significantly decreased after treatment compared with before treatment ( t = 10.39, 12.47, both P < 0.001). The score of the Mini-Mental State Examination in each group significantly increased after treatment compared with before treatment ( t = 8.36, 14.52, both P < 0.001). The scores of BRMS and HAMD post-treatment were significantly lower in the combined treatment group than in the control group ( t = 5.86, 5.54, both P < 0.001). The score of MMSE post-treatment was significantly higher in the combined treatment group than in the control group ( t = 2.40, P = 0.020). The response rate was significantly higher in the combined treatment group than in the control group ( Z = 2.16, P = 0.030). After treatment, serum MDA level significantly decreased in each group compared with before treatment ( t = 8.72, 15.47, both P < 0.001). After treatment, SOD, CAT and GSH-Px levels were significantly increased in each group compared with before treatment (SOD tcontrol group = 2.84, P = 0.006, tcombined treatment group = 4.05, P < 0.001; CAT tcontrol group = 5.20, P < 0.001, tcombined treatment group = 9.86, P < 0.001; GSH-Px tcontrol group = 2.67, P = 0.010, tcombined treatment group = 3.71, P = 0.001). Serum MDA level post-treatment was significantly lower in the combined treatment group than in the control group ( t = 12.38, P < 0.001). Serum SOD and CAT levels post-treatment were significantly higher in the combined treatment group than in the control group ( tSOD = 2.24, P = 0.029; tCAT = 2.72, P = 0.009). There was no significant difference in the incidence of adverse reactions between the combined treatment and control groups [20.00% (6/30) vs. 16.67% (5/30), χ2 = 1.02, P = 0.907). Conclusion:Quetiapine fumarate combined with lithium carbonate can greatly improve clinical symptoms and cognitive function and reduce the over-activation of oxidative stress in patients with bipolar disorder. The combined therapy is of certain clinical application value.
