Rationale: S-citalopram (escitalopram) is the very active moiety of citalopram. It has been shown in many studies to be an effective and safe antidepressant for treating major depressive disorder (MDD). Objective: The aim of our study was to compare the efficacy and safety of escitalopram vs citalopram in Chinese MDD patients. Methods: In the double-blind study, 240 MDD patients were randomly assigned to treatment for 6 weeks either with escitalopram (10-20 mg/d) or citalopram (20-40 mg/d). The primary efficacy measurement was the change of 17-item Hamilton Depression Rating Scale (HAMD-17) total score from baseline to the end of study. The secondary efficacy measurements were response and remission rates. The adverse events (AEs) were recorded by the investigator. Results: Two hundred and three (85%) patients completed the trial. The average dose was 13.9 mg/d in the escitalopram group and 27.6 mg/d in the citalopram group. No significant differences were found between the two groups in the change in HAMD-17 total score, response, and remission rate. These results were similar in severe MDD patients. No significant differences were found between the two groups in AEs. No serious AEs were observed in this study. Conclusions: The study suggests that escitalopram 10-20 mg/d are as effective and safe as citalopram 20-40 mg/d in the short-term treatment for Chinese MDD patients. © 2011 Springer-Verlag.

This study is a pre-registration trial of generic duloxetine that was approved by the China Food and Drug Administration (approval number: 2006L01603).Compare the treatment efficacy and safety of generic duloxetine to that of paroxetine in patients with major depressive disorders (MDD).This was a double-dummy, double-blind, multicenter, positive drug (paroxetine), parallel randomized controlled clinical trial. The 299 patients with MDD recruited for the study were randomly assigned to use duloxetine (n=149; 40-60 mg/d) or paroxetine (n=150; 20 mg/d) for 8 weeks. The Hamilton Depression rating scale (HAMD-17) was administered at baseline and 1, 2, 4, 6, and 8 weeks after starting treatment. Remission was defined as a HAMD-17 score below 8 at the end of the trial, and treatment effectiveness was defined as a decrease in baseline HAMD-17 score of at least 50% by the end of the trial. Safety was assessed based on the reported prevalence and severity of side effects and changes in laboratory and electrocardiographic findings. Three patients in the duloxetine group dropped out before starting medication, so results were analyzed using a modified intention-to-treat (ITT) method with 146 in the experimental group and 150 in the control group.Both groups experienced 29 dropouts during the 8-week trial. HAMD-17 scores decreased significantly from baseline throughout the trial in both groups. Based on the ITT analysis, at the end of the trial there was no significant difference between the duloxetine group and the paroxetine group in effectiveness (67.1% v. 71.3%, X(2)=0.62 p=0.433), remission rate (41.1% v. 51.3%, X(2)=3.12, p=0.077), or in the incidence of side effects (56.8% v. 54.7%, X(2)=0.14, p=0.705).Generic duloxetine is as effective and safe as paroxetine in the acute treatment of patients with MDD who seek care at psychiatric outpatient departments in China.

We carried out a pharmacogenomic study in order to identify susceptible genes for antipsychotics induced weight gain within the Chinese Han population.We enrolled 216 patients with schizophrenia in our study. All of them underwent risperidone monotherapy, and fulfilled 4-week follow-up. Weight gain was measured before treatment and 4 weeks later. Seven hundred and sixty-eight SNPs from 85 genes were calculated for association with weight gain percentage.Fifty-seven SNPs located at 16 genes with a p-value less than 0.05.4 SNPs located on serotonin transporter gene (solute carrier family 6, member 4, SLC6A4) remained significant after multitest correction (rs3813034, p = 0.000357, q = 0.08, rs1042173, rs4325622, rs9303628, p = 0.000451, q = 0.08).SLC6A4 might be susceptible gene for risperidone-induced weight gain within the Chinese Han population.

Antipsychotic-induced weight gain (AIWG) is a serious concern in therapy with antipsychotic medications. To identify single nucleotide polymorphisms (SNPs) associated with AIWG, we conducted a genome-wide association study (GWAS) for antipsychotic treatment.The discovery cohort consisted of 534 patients with schizophrenia, who underwent 8-week treatment with antipsychotics and were genotyped using the Illumina Human 610-Quad BeadChip. The independent replication cohort consisted of 547 patients with schizophrenia, treated with similar antipsychotics, and genotyped using the Sequenom MassARRAY platform. Two hundred and thirty-six drug-naive patients treated with risperidone or quetiapine were analyzed independently. Additionally, we conducted pathway and expression analyses using several public bioinformatics databases.After correction for age and gender, the top 2 genome-wide significant SNPs with AIWG were located in the PTPRD gene (protein tyrosine phosphatase, receptor type D, 9p24-p23; rs10977144, P GWAS = 9.26E-09; rs10977154, P GWAS = 4.53E-08). The third most significant SNP was in the GFPT2 gene (glutamine-fructose-6-phosphate amidotransferase 2, 5q35.3; rs12386481, P GWAS = 1.98E-07). These results were validated in the replication cohort (rs10977144, P Replication = 4.30E-03; rs10977154, P Replication = 6.33E-03; rs12386481, P Replication =7.65E-03). These results were also verified in those patients initially exposed to risperidone and quetiapine (rs10977144, P = 1.97E-05; rs10977154, P = 2.04E-05; rs12386481, P = 1.97E-04). Pathway analyses showed that AIWG may involve in multiple pathways related to metabolic processes. Moreover, PTPRD mRNA might be highly expressed in brain regions, and the SNPs (rs10977144, rs1097154) also showed significant expression quantitative trait locus effects.Our findings indicate that PTPRD polymorphisms might modulate AIWG.

This study examined the use, demographic and clinical correlates of antipsychotic polypharmacy (APP) and its associations with treatment satisfaction and quality of life (QOL) in schizophrenia patients in China.A total of 4239 patients in 45 nationwide Chinese psychiatric hospitals/centers were interviewed in 2012 in the third cross-sectional study, with the first two having been conducted in 2002 and 2006. Patients socio-demographic and clinical characteristics, including psychopathology, side effects, satisfaction with treatment and QOL, were recorded using a standardized protocol and data collection procedure.The proportion of APP prescriptions in 2012 was 34.2%, which was significantly higher than the frequency of APP in 2002 (26.1%) and 2006 (26.4%) (p<0.001). Of patients on APP, 91.1% received two antipsychotics, 8.6% received three and 0.3% received four or more antipsychotics. Multiple logistic regression analyses revealed that compared to those on antipsychotic monotherapy, patients on APP and their families had lower satisfaction with treatment, had higher QOL in the mental domain, younger age of onset, more side effects, higher doses of antipsychotics and were more likely to receive first-generation antipsychotics and less likely to receive benzodiazepines (total R (2)=0.31, p<0.001).APP was found in about one in three schizophrenia patients. The prevalence of APP seems to have been increasing since 2002. Considering the increased frequency of drug-induced side effects and the patients and their relatives dissatisfaction with antipsychotic treatment, further examination of the rationale and appropriateness of APP and its alternatives is warranted.

We examined the time trends and correlates of clozapine use in schizophrenia patients in China.A total of 14,013 patients with schizophrenia treated in 45 psychiatric hospitals/centers nationwide were interviewed in 2002, 2006 and 2012. Patients socio-demographic and clinical characteristics including psychopathology, medication side effects, satisfaction with treatment and quality of life (QOL) were recorded in a standardized fashion.Clozapine was used in 32.9% of the whole sample; with corresponding figures of 39.7%, 32.5% and 26.4% in 2002, 2006 and 2012 (p<0.001). Families of clozapine users had lower satisfaction with treatment than those of the non-clozapine group, without significant differences with respect to patients treatment satisfaction and mental or physical QOL. In multiple logistic regression analyses, compared to the non-clozapine group, patients on clozapine had an earlier age of onset, longer illness duration, more global illness severity and drug-induced central nervous system, gastrointestinal and other side effects, lower antipsychotic doses, less delusions and hallucinations, more negative symptoms, were more likely male, inpatients, to have a family history of psychiatric disorders, receive treatments in regional centers and receive antipsychotic polypharmacy, but less likely to have health insurance and receive first-generation antipsychotics and benzodiazepines (R(2)=0.498, p<0.001).Clozapine was used in one-third of schizophrenia patients in China, with decreasing frequency since 2002. Patients prescribed clozapine had multiple markers of greater global illness severity/chronicity and decreased satisfaction with treatment by the families, but similar QOL and less delusions and hallucinations than patients not prescribed clozapine.

The ataxin-2 binding protein 1 (A2BP1) gene is reported to be one of the susceptibility genes in schizophrenia, autism, and obesity. The aim of this study was to explore the association of A2BP1 gene polymorphisms with antipsychotic induced weight gain (AIWG) in Chinese Han population. Three hundred and twenty-eight patients with schizophrenia were followed-up for an 8-week period of treatment with olanzapine. The fasting weights of 328 patients were measured before and after the 8-week course of treatment. Four single nucleotide polymorphisms (SNPs: rs8048076, rs1478697, rs10500331, and rs4786847) of the A2BP1 gene were genotyped by polymerase chain reaction (PCR). We analyzed putative association of A2BP1 polymorphisms with AIWG of olanzapine using linear regression analysis and found that SNP rs1478697 was significantly associated with AIWG caused by olanzapine (p=0.0012; Bonferroni corrected p=0.0048). The association was replicated in another independent sample including 208 first-episode and drug-nave patients presenting with schizophrenia after a 4-week treatment with olanzapine (p=0.0092; Bonferroni corrected p=0.0368; meta p=5.3310(-5)). To explore the biological plausibility of A2BP1 in the pathogenesis of AIWG, we made expression analyses and eQTL analyses; these analyses showed that A2BP1 was highly expressed in whole brain tissues using the HBT database, and that rs1478697 has an expression quantitative trait locus effect in human cerebellar cortex tissues using the BRAINEAC database (p=2.50E-04). In conclusion, the rs1478697 in A2BP1 may be associated with AIWG induced by 8-week treatment with olanzapine.

This study examined the pattern of adjunctive antidepressant use in schizophrenia patients and its demographic and clinical correlates in a nationwide survey in China.Fourteen thousand and thirteen patients in 45 Chinese psychiatric hospitals or centers were interviewed (4,486 in 2002, 5,288 in 2006, and 4,239 in 2012). Patients sociodemographic and clinical characteristics were recorded using a standardized protocol and data collection procedure. Chi-square test, independent-samples t test, Mann-Whitney U test, and multiple logistic regression analysis were used in data analyses.Antidepressant use was found in 5.2% of the study population with 4.6% in 2002, 4.3% in 2006, and 6.9% in 2012, respectively. A significant increase in use from 2006 to 2012 was found (p<.001). Multiple logistic regression analyses in the whole population revealed that patients receiving adjunctive antidepressants were more likely to be outpatients in tertiary referral centers (level-III hospitals) and who had an earlier age of onset, less severe global illness, but more depressive symptoms. They were less likely to receive first-generation antipsychotics but more likely to receive benzodiazepines (RDespite an increasing trend, the frequency of antidepressant use in schizophrenia in China was considerably lower than in Western countries. The benefits and risks associated with concomitant use of antidepressants in schizophrenia need to be studied further.

Adversity, particularly in early life, can cause illness. Clues to the responsible mechanisms may lie with the discovery of molecular signatures of stress, some of which include alterations to an individuals somatic genome. Here, using genome sequences from 11,670 women, we observed a highly significant association between a stress-related disease, major depression, and the amount of mtDNA (p = 9.00 10(-42), odds ratio 1.33 [95% confidence interval [CI] = 1.29-1.37]) and telomere length (p = 2.84 10(-14), odds ratio 0.85 [95% CI = 0.81-0.89]). While both telomere length and mtDNA amount were associated with adverse life events, conditional regression analyses showed the molecular changes were contingent on the depressed state. We tested this hypothesis with experiments in mice, demonstrating that stress causes both molecular changes, which are partly reversible and can be elicited by the administration of corticosterone. Together, these results demonstrate that changes in the amount of mtDNA and telomere length are consequences of stress and entering a depressed state. These findings identify increased amounts of mtDNA as a molecular marker of MD and have important implications for understanding how stress causes the disease.

This study was designed to examine the validity and reliability of the Chinese version of the Psychotropic-Related Sexual Dysfunction Questionnaire (PRSexDQ-SALSEX) in patients with schizophrenia taking antipsychotics. It was conducted in a sample of 135 patients aged between 18 and 50 years old and diagnosed with schizophrenia. Demographic data and clinical features were assessed with PRSexDQ, the Positive and Negative Syndrome Scale (PANSS), the Clinical Global Impression (CGI), and the Udvalg for Kliniske Undersgelser (UKU) Side Effects Rating Scale. The internal consistency of the Chinese version of PRSexDQ using Cronbachs was 0.902. The test-retest and inter rater reliability was both high with p<0.001. PRSexDQ was correlated with corresponding items in the UKU Side Effects Rating Scale (Items 4.12-4.16), and showed good sensitivity, specificity, positive and negative predictive value. It could also clearly detect differences in SD rates of three monotherapy groups: patients treated with risperidone had the highest scores, followed by patients treated with olanzapine, whereas patients treated with aripiprazole had the lowest scores. The Chinese version of PRSexDQ is a reliable and valid instrument to assess patients with schizophrenia. Assessed by PRSexDQ, 53.2% of total subjects in our study reported symptoms of SD.
