Abstract

The International Schizophrenia Outpatient Health Outcomes study, IC-SOHO is a three-year international observational study that investigates clinical and health outcomes of antipsychotic treatments. 7658 outpatients treated for schizophrenia were enrolled in the study, who needed an antipsychotic therapy to initiate or switch. The primary analysis compared the group taking olanzapine with the group taking any other antipsychotics, while the secondary comparison was performed between those treated with olanzapine and those with risperidone. Efficacy analysis was carried out based on changes in Clinical Global Impression of Severity scale (CGI-S), which was performed at a global symptom level, as well as with respect to the patients' positive, negative, cognitive and depressive symptoms. In addition, adverse events were also evaluated. Results of the analysis of the 3- and 6-month data from Hungary are disclosed in this publication. 200 patients were enrolled in the country. Demographics of the treatment groups were not significantly different. At 3 and 6 months after treatment initiation, there were no significant between-group differences in improvement of global symptomatology, however, cognitive symptoms improved more in the Olanzapine-group compared to those taking other antipsychotics (p<0.05). In patients showing Extrapyramidal Symptoms (EPS) at baseline, these symptoms finished to a greater extent among those receiving olanzapine than in those receiving other antipsychotics (after 6 months D<0.0001). Half a year later, significantly less patients showed extrapyramidal adverse events (p=0,0007), and the previous EPS terminated to a greater extent (p=0.0016) in the olanzapine group, as compared to those taking risperidone. No between-group differences were found in changes of sexual functions, as well as of weight and Body Mass Index measures. Switching antipsychotic initiated at study baseline, and adding-on one or more other antipsychotic to the initial one, were significantly less frequent in the Olanzapine-group compared to those initiated other antipsychotics. In the first 3 months, treatment compliance was significantly higher with olanzapine therapy than with other antipsychotic treatments, and with risperidone respectively. Results from the Hungarian sample correspond with results from higher analysis levels of wider patient populations of IC-SOHO study. Olanzapine showed outstanding efficacy in lessening cognitive disturbances and global clinical symptomatology associated with schizophrenia. Extrapyramidal symptoms of patients treated with olanzapine improved significantly better compared with those patients who received other antipsychotics and risperidone respectively.
