Abstract

ObjectiveTo observe the efficacy and safety of sertraline combined with low-dose olanzapine in the treatment of depression and anxiety comorbidity and its effect on sleep quality， so as to provide references for the related clinical treatment.MethodsA total of 121 patients who met the diagnostic criteria of International Classification of Diseases， tenth edition （ICD-10） for depressive episode and generalized anxiety disorder in The Third People's Hospital of Tianshui and the Sanatorium for Mental Illness of Veterans in Tianshui from October 2019 to August 2020 were enrolled， and they were divided into two groups according to the random number table method. Study group （n=61） received sertraline combined with low-dose olanzapine， while control group （n=60） received sertraline only. Then the disease severity degree， sleep quality and adverse reactions were assessed using Hamilton Depression Scale - 17 item （HAMD-17）， Hamilton Anxiety Scale （HAMA）， Pittsburgh Sleep Quality Index （PSQI） and Treatment Emergent Symptom Scale （TESS） at the baseline， 1st， 2nd， 4th， 6th and 8th weekend， respectively.ResultsPost-treatment HAMD-17， HAMA and PSQI scores in both groups were lower than those before treatment （P<0.05）. At each time point after treatment， HAMD-17， HAMA and PSQI scores of study group were lower than those of control group， with statistical significance （P<0.05）.ConclusionSertraline alone and its combination with low-dose olanzapine are both effective in the treatment of depression and anxiety comorbidity， while the combination therapy achieves better efficacy and higher safety in alleviating anxiety and insomnia symptoms.
