Sertraline plus deanxit to treat patients with depression and anxiety in chronic somatic diseases: a randomized controlled trial

BACKGROUND: Patients in chronic somatic diseases are often accompanied with depression and anxiety, remission of which may be observed in the third or fourth week after applying common antidepressant medications. We investigate the efficacy and safety of sertraline plus deanxit on patients with depression and anxiety in chronic somatic diseases. METHODS: 75 Patients who met the criteria were randomly assigned to deanxit group or placebo group: sertraline (75 mg/day) plus deanxit (one piece/day) (N = 38), or sertraline (75 mg/day) plus placebo (one piece/day) (N = 37) for 2 weeks, both groups received sertraline (75 mg/day) in the following 2 weeks. Changes from baseline to day 4, day 8, day 15, and day 29 in Hamilton Rating Scale for Depression (HAM-D) and Hamilton Rating Scale for Anxiety (HAM-A) total scores were the efficacy measures. Adverse events were monitored and registered systematically during the trial. RESULTS: Response rates for HAM-D scores in deanxit group and placebo group were significantly different on day 8(55.26% ± 2.56% VS 24.32% ± 2.19%, p = 0.006) and day 15(78.95% ± 3.89% VS 40.54% ± 4.18%, p = 0.001), while no statistical differences were observed on day 4 and day 29. Respectively, response rates for HAM-A scores on day 4 (34.21% ± 2.21% VS 8.11% ± 1.37%, p = 0.006), day 8 (57.89% ± 3.56% VS 18.92% ± 2.68%, p = 0.001) and day 15 (78.95% ± 4.37% VS 43.24% ± 4.68%, p = 0.002), favoring the deanxit group. However, HAM-A scores were not remarkably different at the end point. The overall safety profile of both groups was favorable with no distinct differences. CONCLUSIONS: The efficacy was exhibited in the deanxit group, with evidence for similar safety. The rapid onset of sertraline plus short-term deanxit indicated that it might be an inspiring strategy to manage depression and anxiety within the first two weeks in chronic somatic diseases.
