摘　　要：目的探讨中老年抑郁症患者血清皮质醇、硫化脱氢表雄酮(dehydroepiandrosterone sulfate,DHEAS)及二者比率在治疗前后的变化。方法对40例中老年期首发抑郁症患者在治疗前及西酞普兰20mg/d治疗6周后进行血清皮质醇、DHEAS的浓度测定,并和40名正常对照进行比较。采用24项汉密尔顿抑郁量表(HAMD)评定患者症状。结果治疗前患者组血清皮质醇和皮质醇/DHEAS比率明显高于正常对照组(P<0.01),而DHEAS明显低于对照组(P<0.01),治疗6周后上述指标均明显改善(P<0.01和P<0.05),但均仍与对照组有差异(P<0.05)。治疗前,轻度抑郁组和重度抑郁组与对照组的血清皮质醇、DHEAS、皮质醇/DHEAS比率的差异均有统计学意义(P<0.05),重度组3个指标的异常均较轻度组更明显(P<0.05或P<0.01),治疗后两组差异无统计学意义(P>0.05)。治疗前,患者组的DHEAS含量、皮质醇/DHEAS比率均与HAMD分值有线性回归关系;而治疗前后皮质醇/DHEAS比率变化与HAMD减分率明显相关(r=0.42,P<0.01)。结论中老年期抑郁症患者血清皮质醇、DHEAS、皮质醇/DHEAS比率存在异常,均与抑郁程度相关,比率的变化与抑郁症状的改善有关。Objective To analyze the changes of the eortisol,dehydroepiandrosterone sulfate （DHEAS） and the ratio of corfisol/DHEAS in middle-aged patients with depression before and after treatment. Methods Forty middle-age people with depression and 40 health middle-aged people were recruited in the study. Serum cortisol and DHEAS levels were measured before and six months after treatment with citalopram hydrobromide 20 mg/d using ELISA. Depression symp- toms were evaluated using Hamilton depression scale（HAMD）. Results Before treatment, serum cortisol levels, the ratio of cortisol/DHEAS were significantly higher and serum DHEAS levels were significantly lower in patient group than in con- trol group （P 〈0. O1 ）. Six weeks after treatment, serum cortisol levels, the ratio of cortisol/DHEAS and serum DHEAS levels were significantly improved in patient group although still abnormal. Before treatment, there was a significant differ- ence in serum cortisol, DHEAS levels and the ratio of cortisol/DHEAS among moderate patient group, severe patient group and control group（P 〈0. 05, P 〈0. 01）and the abnormality of these parameters were more obvious in severe group than in moderate group（P 〈0. 05, P 〈0. 01 ）. After treatment, there was no significant difference in these three parameters between moderate group and severe group. The serum DHEAS levels and the ratio of cortisol/DHEAS have a linear regression relation with the value of HAMD in patient group before treatment. The change of the ratio of cortisol/DHEAS before and after treat- ment is associated with the reduced value of HAMD （ r = 0. 42,P 〈 0. 01 ）. Conclusions Elderly patients with depression have abnormality in serum cortisol, DHEAS levels and the ratio of cortisol/DHEAS and the abnormality is associated with the de- gree of depression. The change of the rate of cortisol/DHEAS is associated with the improvements in depressive symptoms.
