Detailed Description

OBJECTIVE: This study aimed to evaluate the treatment effect of combination low-dose antipsychotics with low-dose sertraline in 1640 schizophrenia patients

METHODS:

  1. atypical antipsychotics and dose: including four atypical antipsychotics to form eight treatment groups: 1) olanzapine (7.5-10mg/day) combined with sertraline (50-100mg/day) group 2) only olanzapine (12.5-20mg/day) group 3) risperidone (2-3.5mg/day) combined with sertraline (50-100mg/day) group 4) only risperidone (4-6mg/day) group 5) paliperidone (3-4.5mg/day) combined with sertraline (50-100mg/day) group 6) only paliperidone (6-9mg/day) group 7) ziprasidone (60-100mg/day) combined with sertraline (50-100mg/day) group 8) only ziprasidone (120-160mg/day) group
  2. blood biochemical examination: including blood routine examination, liver function, renal function, thyroid function, glucose and lipid level, prolactin, and related hormones and proteins
  3. electrophysiological examination: including electrocardiograph, electroencephalography (EEG), and brain evoked potential
  4. scale assessment: each patient was assessed by four clinical psychiatrists using the following scales: 1) psychopathology: positive and negative symptoms scale (PANSS) and clinical global impression scale (CGI-S) 2) emotional symptoms: Hamilton depression rating scale (HAMD) and Hamilton anxiety rating scale (HAMA) 3) social function: personal and social performance scale (PSP) 4) side-effect: treatment emergent side-effect scale (TESS) and rating sale for extrapyramidal side-effect (RESES)
  5. blood drug concentration assay: including the drug concentration of olanzapine, risperidone, paliperidone, ziprasidone and sertraline, respectively
  6. Weigh gain measurement: to measure height, weight for each patient

The above measurement data were collected at baseline, week4, week8, week 12 and week24.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
changes in psychopathology symptoms on PANSS during antipsychiatric treatment
Time Frame: baseline, week 4, week 8, week 12, and week 24
The Positive and Negative Syndrome Scale (PANSS) is a well-characterized and widely applied dimensional assessment that reflects a balanced representation of positive and negative syndromes, their differential and general severity of illness. The scales not only measures positive and negative syndromes, but also suggests their differential and general severity of the illness. The items on the PANSS are defined with increasing levels from 1 to 7: 1 = absent, 2 = minimal, 3 = mild, 4 = moderate, 5 = moderate-severe, 6 = severe, and 7 = extreme. Then the PANSS score is totaled by sum up the ratings across different items, the potential range for positive and negative scales are from 7 to 49 whereas the General Psychopathology Scale is ranged between 16 to 112.
baseline, week 4, week 8, week 12, and week 24
changes in depressive symptoms on HAMD during antipsychiatric treatment
Time Frame: baseline, week 4, week 8, week 12, and week 24
HAMD stands for Hamilton Rating Scale. It is the assessment that designed for examining the treatment significant of depression severity. The general format contains 17 items, 12 of them are scored from 0 to 4 while the rest of them ranges from 0 to 2. The items represented a variety of aspects: Depression mood, Feeling of guilt, Suicide, Insomnia early, Insomnia middle, Insomnia late, Work and activities, Motor retardation, Agitation, Psychic anxiety, Somatic anxiety, Somatic symptoms(gastrointestinal), somatic symptoms(general), Genital symptoms (sexual interest). Hypochondriasis, Weight loss and Insight. So A cut-off score less than or equal to 7 in the HAMD scale defines the symptomatic remission.
baseline, week 4, week 8, week 12, and week 24

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
changes in electroencephalography examination for brain activity during antipsychiatric treatment
Time Frame: baseline, week 4, week 8, week 12, and week 24
electroencephalography, or EEG is the physiological method of choice to record the electrical activity generated by the brain via electrodes placed on the scalp surface. For faster application, electrodes are mounted in elastic caps similar to bathing caps, ensuring that the data can be collected from identical scalp positions across all respondents. By analysis of frequency and amplitude of five kind of brain waves(delta, theta, alpha, beta, gamma) , we could detect the synchronized activity of neurons within cortical areas even at sub-second timescales
baseline, week 4, week 8, week 12, and week 24
