Subjective response to antipsychotic treatment and compliance in schizophrenia. A naturalistic study comparing olanzapine, risperidone and haloperidol (EFESO Study)

BACKGROUND: In order to compare the effectiveness of different antipsychotic drugs in the treatment of schizophrenia it is very important to evaluate subjective response and compliance in patient cohorts treated according to routine clinical practice. METHOD: Outpatients with schizophrenia entered this prospective, naturalistic study when they received a new prescription for an antipsychotic drug. Treatment assignment was based on purely clinical criteria, as the study did not include any experimental intervention. Patients treated with olanzapine, risperidone or haloperidol were included in the analysis. Subjective response was measured using the 10-item version of the Drug Attitude Inventory (DAI-10), and treatment compliance was measured using a physician-rated 4 point categorical scale. RESULTS: A total of 2128 patients initiated treatment (as monotherapy) with olanzapine, 417 with risperidone, and 112 with haloperidol. Olanzapine-treated patients had significantly higher DAI-10 scores and significantly better treatment compliance compared to both risperidone- and haloperidol-treated patients. Risperidone-treated patients had a significantly higher DAI-10 score compared to haloperidol-treated patients. CONCLUSION: Subjective response and compliance were superior in olanzapine-treated patients, compared to patients treated with risperidone and haloperidol, in routine clinical practice. Differences in subjective response were explained largely, but not completely, by differences in incidence of EPS

Characterization of Bridging Integrator 1 (BIN1) as a Potential Tumor Suppressor and Prognostic Marker in Hepatocellular Carcinoma

It has been shown that bridging integrator 1 (BIN1) can interact with c-myelocytomatosis (c-Myc) oncoprotein in cancer. However, the role of BIN1 in hepatocellular carcinoma (HCC) is not clear. In the present study, we investigated the expression and prognostic role of BIN1 in primary HCC and evaluated the function of BIN1 in hepatocarcinogenesis. Using real-time polymerase chain reaction and Western blot analysis, we found significantly decreased expression of BIN1 in primary HCC tumor tissues (n = 42) compared with adjacent normal tissues and in HCC cell lines. Immunohistochemistry analysis also found decreased BIN1 expression in HCC tumor tissues (n = 117). In clinicopathological analysis, loss of BIN1 expression correlated significantly (P < 0.05) with differentiation scores and tumor size. Importantly, decreased expression of BIN1 in tumors was found to be closely associated with a poor prognosis, and we conclude that BIN1 was an independent prognostic factor in a multivariate analysis. In mechanistic studies, restoring BIN1 expression in BIN1-null HCC cells significantly inhibited cell proliferation and colony formation and induced apoptosis of HCC cells. Furthermore, we found that BIN1 overexpression could significantly suppress the motility and invasion of HCC cells in vitro. Our results indicate that BIN1 may function as a potential tumor suppressor and serve as a novel prognostic marker in HCC patients. The BIN1 molecule might play an important role in tumor growth, cell motility and invasion. Modulation of BIN1 expression may lead to clinical applications of this critical molecule in the control of hepatocellular carcinoma as well as in early and effective diagnosis of this aggressive tumor
