[Show abstract][Hide abstract] ABSTRACT: The relative effectiveness of the atypical antipsychotic drugs and conventional agents in patients with early-stage schizophrenia has not been comprehensively determined.
The aim of our study was to evaluate the efficacy and safety of seven antipsychotic drugs for the maintenance treatment in patients with early-stage schizophrenia.
In a 12-month open-label, prospective observational, multicenter study, 1,133 subjects with schizophrenia or schizophreniform disorder within 5 years of onset were monotherapy with chlorpromazine, sulpiride, clozapine, risperidone, olanzapine, quetiapine, or aripiprazole. The primary measure was the rate of treatment discontinuation for any reason. Secondary outcomes included measures for clinical and functional outcomes and tolerability.
The percentage of patients discontinued treatment within 12 months was 41.4% for chlorpromazine, 39.5% for sulpiride, 36.7% for clozapine, 40.2% for risperidone, 39.6% for olanzapine, 46.9% for quetiapine, and 40.2% for aripiprazole, a nonsignificant difference (p = 0.717); there were no significant differences among these seven treatments on discontinuation due to relapse, intolerability, patient decision, or nonadherence (all p values ≥ 0.260). Extrapyramidal symptoms were more prominent in chlorpromazine and sulpiride treatment groups. Anticholinergic side effects were most common with clozapine and chlorpromazine. Weight gain was most common with olanzapine and clozapine.
The efficacy of seven antipsychotic medications for the maintenance treatment appeared similar in early-stage schizophrenia. With regard to the high dropout rate and side effects, special programs are needed to keep efficacy and safety of antipsychotics maintenance treatment for schizophrenia with early stage.

[Show abstract][Hide abstract] ABSTRACT: Antipsychotic drugs are limited in their ability to improve the overall outcome of schizophrenia. Adding psychosocial treatment may produce greater improvement in functional outcome than does medication treatment alone.
To evaluate the effectiveness of antipsychotic medication alone vs combined with psychosocial intervention on outcomes of early-stage schizophrenia.
Randomized controlled trial.
Ten clinical sites in China.
Clinical sample of 1268 patients with early-stage schizophrenia treated from January 1, 2005, through October 31, 2007. Intervention Patients were randomly assigned to receive antipsychotic medication treatment only or antipsychotic medication plus 12 months of psychosocial intervention consisting of psychoeducation, family intervention, skills training, and cognitive behavior therapy administered during 48 group sessions.
The rate of treatment discontinuation or change due to any cause, relapse or remission, and assessments of insight, treatment adherence, quality of life, and social functioning.
The rates of treatment discontinuation or change due to any cause were 32.8% in the combined treatment group and 46.8% in the medication-alone group. Comparisons with medication treatment alone showed lower risk of any-cause discontinuation with combined treatment (hazard ratio, 0.62; 95% confidence interval, 0.52-0.74; P < .001) and lower risk of relapse with combined treatment (0.57; 0.44-0.74; P < .001). The combined treatment group exhibited greater improvement in insight (P < .001), social functioning (P = .002), activities of daily living (P < .001), and 4 domains of quality of life as measured by the Medical Outcomes Study 36-Item Short Form Health Survey (all P < or = .02). Furthermore, a significantly higher proportion of patients receiving combined treatment obtained employment or accessed education (P = .001).
Compared with those receiving medication only, patients with early-stage schizophrenia receiving medication and psychosocial intervention have a lower rate of treatment discontinuation or change, a lower risk of relapse, and improved insight, quality of life, and social functioning.

[Show abstract][Hide abstract] ABSTRACT: To compare the effect of 7 antipsychotic drugs on the life quality of schizophrenia patients including chlorpromazine, sulpiride, clozapine, risperidone, olanzapine, quetiapine, and aripiprazole.
A total of 1,227 stable schizophrenic patients within 5 years onset who took 1 of the 7 study medications as maintenance treatment were followed up for 1 year at 10 China sites. Patients were evaluated by the short form-36 health survey (SF-36) at the baseline and at the end of 1 year.
The life quality was improved obviously at the end of the follow-up. There was significant difference in body pain, vitality, and mental health (P<0.05) among these antipsychotic drugs.
All 7 antipsychotic drugs can improve the life quality of schizophrenia patients. Atypical antipsychotic drugs, especially olazapine and quetiapine, are superior to typical antipsychotic drugs in improving life quality.
