We investigated the influence of somatic symptoms on the severity and clinical outcomes in female Korean patients with major depressive disorder (MDD) in routine practice.Two hundred and seven female patients with MDD were prospectively recruited. Patients with somatic symptoms (PSS) was defined as a total score ≥ 10 on the Patient Health Questionnaire-15 (PHQ-15), others were classified as non PSS (NPSS). The PHQ-9 for de-pression, the Generalized Anxiety Disorder Scale (GAD-7) for anxiety, the Clinical Global Impression-Severity (CGI-S) for clinical status, and the Visual Analogue Scale (VAS) for health status were utilised.Of 207 participants, 126 (60.9%) were PSS and 81 (39.1%) were classified as NPSS. The proportion of patients showing severe symptoms (65.1% vs. 24.7%) and recurrence of depression (74.6% vs. 49.4%), the CGI-S (4.6 vs. 4.1), the PHQ-9 (16.8 vs. 11.1), and the GAD-7 (8.3 vs 6.7) scores were significantly higher in PSS than in NPSS, while the VAS (39.4 vs. 51.2) was significantly lower in PSS than in NPSS. The improvement of depressive symptoms (-1.3 vs. -2.0) measured by the changes in CGI-S was also significantly less in PSS than in NPSS after 6 months treatment.Our findings have shown the significant impact of somatic symptoms on the symptomatology as well as treatment outcomes in Korean female patients with MDD, indicating that clinicians should carefully evaluate somatic symptoms in patients with MDD in routine clinical practice. Due to the methodological shortcomings of the present study, further adequately powered and well-designed investigations are necessary.
Paliperidone, an active metabolite of risperidone, is the most recent second-generation antipsychotic to become available on the market. This article addresses the pharmacology, clinical efficacy and tolerability of paliperidone. A comprehensive review of studies on MEDLINE using terms, such as paliperidone, 9-hydroxy risperidone, efficacy and tolerability, was conducted. Paliperidone, a 9-hydroxy derivative of risperidone is an antagonist at the dopamine and serotonin receptor sites. As paliperidone is an active metabolite of the parent compound risperidone, it is not metabolized hepatically, has minimal drug-drug interactions and is largely excreted unchanged by the kidneys. It follows linear pharmacokinetics. Evidence from short- and long-term trials supports the efficacy and tolerability of paliperidone extended release (ER) in the treatment of schizophrenia. Randomized, double-blind, placebo-controlled, multicenter studies have demonstrated both paliperidone 6 and 12 mg result in symptom improvement, increase in time of first recurrence of psychotic symptoms as well as significant improvements in personal and social performance. Studies demonstrated increases in plasma prolactin levels and extrapyramidal symptoms with paliperidone ER treatment compared with placebo. Changes in blood glucose and lipid levels with paliperidone ER were comparable to placebo. Overall, paliperidone is an efficacious, well-tolerated addition to the treatment armamentarium for schizophrenia.
A hypo-estrogenic status, as that occurring with menopause, has been proposed to negatively affect cognitive function in post-menopause women. Nevertheless, little is known about the improvement of cognitive functions during antidepressant treatment in post-menopausal women with major depressive disorder (MDD) and its relation with hormonal changes. Hence, this study aimed to investigate the role of menopausal status including the level of sex hormones on cognitive function during antidepressant treatment.Thirty-nine female patients (n=17 in pre-menopause; n=22 in post-menopause) with MDD based on DSM-IV criteria and who were not on hormonal replacement therapies participated in a prospective, 6-week, open-label naturalistic study. All patients were recruited in a university-based hospital. The Hamilton rating scale for Depression (HAMD), Montgomery-Asberg Depression Rating Scale (MADRS) and the Cognitive Failure Questionnaire (CFQ) were administered at baseline, week 1, week 3, and week 6. Levels of follicle stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2) were collected at baseline visit.Cognitive functioning improved during antidepressant treatment in the overall sample (P=0.00001). In post-menopausal women, E2 levels were strongly correlated with CFQ scores at each measurement. After controlling for depression severity, E2 levels maintained a significant association with the baseline CFQ scores (regression analysis: beta= -0.55 P=0.010; correlation: R= -0.54). In addition, the reduction of CFQ scores during antidepressant treatment was significantly associated with E2 levels (P=0.021), independently from the improvement of depressive symptoms, which however had a strong effect (P=0.0003). Nevertheless, we failed to find any association of CFQ score with sex hormones in pre-menopausal women.In post-menopausal women, the CFQ scores were correlated with E2 levels and the reduction of CFQ score during antidepressant treatment was also dependent on E2 levels, even controlling for depressive symptoms severity.The present study further supports a crucial role of E2 on the cognitive function in post-menopause women. Moreover, our results suggest that E2 may influence the improvement of cognitive function in post-menopause women with MDD, during treatment with antidepressants.
<i>Objectives:</i> Psychotic agitation of psychiatric patients is a common manifestation that needs emergent management. Traditionally, parenteral or intramuscular injection of antipsychotics was conducted for treatment of psychotic agitation. Considering that the rapidly absorbed form of risperidone (risperidone orodispersible tablet) could be used for the agitated patient, comparison of oral risperidone and intramuscular haloperidol was performed in emergency treatment of psychotic agitation in this study. <i>Methods:</i> 124 patients with psychotic agitation were recruited at the emergency room or inpatient ward. They were randomly assigned to either the group of oral risperidone or intramuscular haloperidol. Efficacy of both treatments was measured and compared using the 5-item acute agitation cluster from the Positive and Negative Syndrome Scale-Excited Component (PANSS-EC) and the Clinical Global Impression-Severity of Illness Scale (CGI-S). Tolerability and safety were also compared between the two groups. <i>Results:</i> The PANSS-EC and CGI-S scores were significantly decreased over time in both treatment groups without any significant group difference and time by group interaction effect (F = 459.7, p < 0.0001). There were no serious adverse events in both groups. <i>Conclusion:</i> For the emergency treatment of psychotic agitation, risperidone orodispersible tablet was as effective and tolerable as intramuscular administration of haloperidol. Therefore, we might choose oral medication instead of intramuscular injection for treatment of patients with acute psychotic agitation.
