首发精神分裂症病人的抑郁症状

目的探讨首发精神分裂症病人抑郁症状的发生率、特征及相关因素。方法于入院、治疗3、6、9、12月时用汉密尔顿抑郁量表(HAMD)、简明精神病评定量表(BPRS)、阴性症状量表中文版(SANS-CV)、临床总体印象量表(CGI)及功能总体评定量表(GAF)对164例首发精神分裂症患者进行评定。结果急性期首发精神分裂症病人轻度或以上程度抑郁症状的发生率为71%，但在缓解期降至12%。急性期突出的抑郁表现为认知障碍与迟缓(因子分各占HAMD总分的35%和29%)。抑郁症状随着精神病性症状的缓解而减轻，与性别、发病年龄、受教育时间、病程及前驱期长短无关。HAMD总分在急性期仅与BPRS的焦虑抑郁因子分有关，但在缓解期与阴阳性症状、临床总体印象以及总体功能均有密切的相关性；急性期以及治疗3个月时的抑郁症状与随后的阴阳性症状、总体功能的变化无关。结论首发精神分裂症急性期的抑郁症状可能是一个独立的症状群，抑郁程度不能作为预测首发精神分裂症病人预后的指标。

Depressive symptoms in first episode schizophrenic patients.

Objective 　To investigate the prevalence, characteristics and correlates of depressive symptoms in first episode schizophrenic patients. Methods　To examine 164 first episode schizophrenic patients at the time of admission and at 3,6,9, and 12 months after starting treatment using the HAMD, BPRS, the Chinese version of SANS, CGI and GAF. Results　71% of the patients had depressive symptoms (mild or more) at damission, but the prevalence of depressive symptoms dropped to a mean of 12% during the recovery period. The most prominent depressive symptoms during the acute phase of schizophrenia were ‘cognitive disturbance’ and ‘retardation’ (the respective subscales constituted 35% and 29% of the total HAMD score on admission). Depressive symptoms improved in parallel with the schizophrenic illness. The severity of depressive symptoms was not related to gender, age of onset, educational level, duration of prodromal period or duration of illness. At admission the severity of depressive symptoms was only related to the BPRS anxiety and depression subscale score, but during the recovery period the HAMD total score was significantly correlated with all of the other clinical scales. The level of depressive symptoms at admission and at three months after starting treatment was not related to the subsequent course of positive or negative symptoms. Conclusions　Depressive symptoms appeared to be a separate symptom cluster during the acute phase of first episode schizophrenia. The severity of depressive symptoms did not predict the clinical outcome of first episode schizophrenic patients.
