Abstract:
BACKGROUND: Neurasthenia is commonly believed attributing to the complex influence of psychological, social and biological factors.OBJECTIVE: To probe the correlation of neurasthenia with personality,life events and the positive rate of serum Epstein-Barr (EB) virus.DESIGN: Case-controlled observation and prospective paired analysis.SETTING: Mental Health Institute of Second Xiangya Hospital Affiliated to Central South University.PARTICIPANTS: From May to October 2000, patients with neurasthenia,selected from the Clinical Ward of Mental Health Institute of Second Xiangya Hospital Affiliated to Central South University for medical treatment,19 males and 11 females, with mean age of (27±8), the course of disease ranged from 0.5 to 20 years with the average of 4.0 years, enrolled in this study. According to 1:1 paired principle, 30 matched volenteers, their relatives, or students of Xiangya Hospital were randomly selected as controls.Two groups were matched in age, sex and education, patients with psychological and physical disease were excluded. All participants were given written informed consent.METHODS: The level of serum EB virus IgG and IgM of two groups were determined by using ELISA methods. Blood samples were colleted before and after treatment in experimental group, while blood samples were only collected once in control group. Patients in experimental group were given routine medication and integrative psychotherapy according to their state of illness, and Eysenck personality questionnaire (EPQ) were filled in before and after treatment (including four dimensionalities: neuroticism, psychoticism, extroversion/introvision and lie, amongst which higher scores for extroversion/introvision dimensionality represented extroversion and lower dimensionality represented introvision; higher scores of neuroticism dimensionality suggested anxiety and worry. Higher scores for psychoticism suggested solitude and inadaptability to the outer environment), life events scale (including the total score for life events, positive events value and negative events value), and symptom checklist 90 (SCL-90) (consists of 10 factors scored of 0-4, representing non-symptom to severer symptom) were used to assess the clinical symptom. EPQ and SCL-90 were adopted on patients at four months after treatment for self-comparison. EPQ and life events scale were taken on healthy controls, the scores compared with that of experimental group before treatment.for EPQ, the total scores for SCL-90 and positive rate of EB virus in patients with neurasthenia before and after treatment.RESULTS: Totally 27 patients were followed up at 4 months after treatment, and 3 cases lost due to long distance from hospital, thereby 27 cases in experimental group and 30 cases in control group were remained in the roticism in neurasthenia group was significantly higher than that of control group (57.59±10.79, 40.58±8.68, t=6.536, P ＜ 0.01), scores of extroversion/introvision were obviously lower than that of control group (46.31 ±10.79, 53.50±11.28, t=3.203, P ＜ 0.01). In neurasthenic group, scores for neuroticism was obviously decreased after treatment in contrast to before events scale: The total scores and negative scores in neurasthenia group was significantly higher than that of control group (19.73±17.25, 18.93 tal scores for SCL-90: The total scores for SCL-90 was obviously declined after treatment comparing to that of before treatment in neurasthenia of EB virus IgG and IgM: The positive rate in neurasthenia group was significantly higher than that of control group (76.67% vs 26.67% );and positive rate of serum EB virus were proved to be two important pathogenic factors for neurasthenic patients.CONCLUSION: Patients with neurasthenia possess susceptible personality, such as neuroticism and introvision, and commonly experienced negative life events before illness. Moreover the positive rate of EB virus in neurasthenic patients is higher, which might be associated with the higher glucocorticoidinduced EB virus activation under stress state.
