Psychometric Properties of the Hypomania Checklist-32 in Korean Patients with Mood Disorders.

OBJECTIVE: The aim of this study was to examine the validity of the Korean version of the Hypomania Checklist-32, second revision (HCL-32-R2) in mood disorder patients. METHODS: A total of 454 patients who diagnosed as mood disorder according to Structured Clinical Interview for DSM-IV Axis I Disorders, clinician version (SCID-CV) (bipolar disorder [BD] I, n=190; BD-II, n=72; and major depressive disorder [MDD], n=192) completed the Korean module of the HCL-32-R2 (KHCL-32-R2). RESULTS: The KHCL-32-R2 showed a three-factorial structure (eigenvalue ＞2) that accounted for 43.26% of the total variance. Factor 1 was labeled "active/elated" and included 16 items; factor 2, "irritable/distractible" and included 9 items; and factor 3 was labeled "risk-taking/indulging" and included 9 items. A score of 16 or more on the KHCL-32-R2 total scale score distinguished between BD and MDD, which yielded a sensitivity of 70% and a specificity of 70%. MDD and BD-II also could be differentiated at a cut-off of 15 with maximized sensitivity (0.67) and specificity (0.66). Cronbach's alpha of KHCL-32-R2 and its subsets (factors 1, 2, and 3) were 0.91, 0.89, 0.81 and 0.79, respectively. Correlations between KHCL-32-R2 and Montgomery- Asberg Depression Rating Scale, Young Mania Rating Scale and Korean version of Mood Disorder Questionnaire were -0.66 (p=0.41), -0.14 (p=0.9), and 0.61 (p＜0.001), respectively. CONCLUSION: The KHCL-32-R2 may be a useful tool in distinguishing between bipolar and depressive patients in clinical settings.

Effects of switching to aripiprazole from current atypical antipsychotics on subsyndromal symptoms and tolerability in patients with bipolar disorder.

We evaluated the effectiveness of aripiprazole among bipolar patients who had switched to this medication as a result of difficulty maintaining on their prestudy atypical antipsychotics (AAPs) because of subsyndromal mood symptoms or intolerance. This study included 77 bipolar patients who were in syndromal remission with an AAP as monotherapy or with an AAP combined with a mood stabilizer(s) who needed to switch from their present AAP because of subsyndromal symptoms or intolerance. At 24 weeks after switching to aripiprazole, the remission rates on the Montgomery-Åsberg Depression Rating Scale (MADRS) and on both the MADRS and the Young Mania Rating Scale were increased significantly in the full sample and in the inefficacy subgroup. In the inefficacy subgroup, the MADRS score change was significant during the 24 weeks of study. Total cholesterol and prolactin decreased significantly after switching to aripiprazole. The proportion of patients who had abnormal values for central obesity and hypercholesterolemia decreased significantly from baseline to week 24. These findings suggest that a change from the current AAP to aripiprazole was associated with improvement in subsyndromal mood symptoms and several lipid/metabolic or safety profile parameters in patients with bipolar disorder with tolerability concerns or subsyndromal mood symptoms.

Current prescription pattern of maintenance treatments for bipolar patients in Korea: A focus on the transition from acute treatments.

AIMS: We examined prescription patterns in maintenance treatment for recovered bipolar patients and compared these with acute treatments. METHODS: Using retrospective methods, the bipolar patients in clinical recovery (Clinical Global Impression Bipolar Version score ≤ 2 for 6 months) after acute episode were selected. We reviewed differences between prescription patterns at remission and after a maintenance period of at least 6 months. RESULTS: A total of 340 bipolar disorder patients were selected. During the maintenance period, more than half of the patients (192, 56.5%) took a mood stabilizer (MS) + antipsychotic (AP) combination. Among the MS, valproate (149, 43.8%) was most prescribed, and lithium (98, 28.8%) was second, but as patients moved into maintenance treatment, lithium use decreased, and the use of lamotrigine (86, 25.3%) increased. Preferred AP were quetiapine (125, 36.8%), aripiprazole (67, 19.7%), risperidone (48, 14.1%), and olanzapine (39, 11.5%). The use of olanzapine in maintenance was greatly decreased compared with that during acute treatment (67, 19.7%). Most patients did not take an antidepressant (AD), but the proportion using one or more AD was increased during maintenance (17.9% to 30.3%), and bupropion (28, 8.2%) was the preferred AD. Doses were decreased in all drugs, but lamotrigine was maintained at a dose of 133.2 ± 68.5 mg/day. CONCLUSIONS: The most common prescription combination for bipolar maintenance treatment was MS + AP. The use of AP was decreased, whereas the use of AD in combination with MS and/or AP was increased. The doses of MS and AP were generally decreased during the maintenance periods, with the exception of lamotrigine.

Association between TLR1 polymorphisms and alopecia areata.

Toll-like receptors (TLRs) may contribute to the process of autoimmune attacks on hair follicles. To investigate whether the TLR1 gene polymorphisms are associated with the development and clinical features of alopecia areata (AA), a case-control comparison of two single nucleotide polymorphisms (SNPs) (rs4833095, Asn248Ser and rs5743557, -414C > T) of TLR1 were studied in 239 AA patients and 248 controls. Using multiple logistic regression model, odds ratios, 95% confidence intervals and corresponding p values were estimated. Clinical features were analyzed based on the age of onset, family history, type of AA, nail involvement and body hair involvement. The missense SNP rs4833095 was significantly associated with the development of AA (codominant2, p = 0.002; recessive, p = 0.001; log-additive, p = 0.0071; and allele frequency, p = 0.0066). The promoter SNP rs5743557 was weakly associated with the development of AA (codominant2, p = 0.019; recessive, p = 0.032; log-additive, p = 0.020; and allele frequency, p = 0.03). In the clinical features, rs4833095 was only weakly associated with age of onset between 15 and 50 years (codominant2, p = 0.043 and recessive, p = 0.022). The results suggest that rs4833095 of TLR1 may be associated with the susceptibility for AA in the Korean population.

Korean medication algorithm for depressive disorder: comparisons with other treatment guidelines.

We aimed to compare the recommendations of the Korean Medication Algorithm Project for Depressive Disorder 2012 (KMAP-DD 2012) with other recently published treatment guidelines for depressive disorder. We reviewed a total of five recently published global treatment guidelines and compared each treatment recommendation of the KMAP-DD 2012 with those in other guidelines. For initial treatment recommendations, there were no significant major differences across guidelines. However, in the case of nonresponse or incomplete response to initial treatment, the second recommended treatment step varied across guidelines. For maintenance therapy, medication dose and duration differed among treatment guidelines. Further, there were several discrepancies in the recommendations for each subtype of depressive disorder across guidelines. For treatment in special populations, there were no significant differences in overall recommendations. This comparison identifies that, by and large, the treatment recommendations of the KMAP-DD 2012 are similar to those of other treatment guidelines and reflect current changes in prescription pattern for depression based on accumulated research data. Further studies will be needed to address several issues identified in our review.

One-year rehospitalization rates of patients with first-episode bipolar mania receiving lithium or valproate and adjunctive atypical antipsychotics.

AIM: We compared the 1-year rehospitalization rates of first-episode bipolar manic patients who were discharged while being treated with lithium or valproate in combination with an atypical antipsychotic. METHODS: We investigated the rehospitalization status of first-episode bipolar manic patients who were discharged between 1 January 2003 and 31 December 2010 while they were taking lithium or valproate in combination with aripiprazole, olanzapine, quetiapine, or risperidone. Rehospitalization rates during a 1-year period after discharge were compared between the group receiving lithium plus an atypical antipsychotic and the group receiving valproate plus an atypical antipsychotic using the Kaplan-Meier method. A Cox regression model was used to analyze covariates hypothesized to affect time to rehospitalization. RESULTS: The rehospitalization rate was 17.3% during the 1-year follow-up period. We found significant differences in the rehospitalization rates of patients in the lithium (23.1%) and the valproate (13.3%) groups using the Kaplan-Meier formula. According to Cox proportional hazards regression analysis, higher Clinical Global Impression-Bipolar Version-Severity score at discharge (P = 0.005) and lithium treatment (P = 0.055) contributed to the risk of rehospitalization. CONCLUSION: Treatment with valproate and an atypical antipsychotic can be more effective than treatment with lithium and an atypical antipsychotic in preventing rehospitalization during the 1 year after hospitalization due to a first manic episode in patients with bipolar I disorder. Higher Clinical Global Impression-Bipolar Version-Severity scores at discharge also negatively affected rehospitalization rates.

The efficacy and safety of switching to ziprasidone from olanzapine in patients with bipolar I disorder: an 8-week, multicenter, open-label study.

BACKGROUND: Switching antipsychotic medication in patients undergoing combination therapy for bipolar I disorder is a common clinical practice because of suboptimal drug efficacy or tolerability. Despite the frequency of switching, little is known about the most appropriate switching options. Ziprasidone may be a good alternative for patients with bipolar disorder experiencing a suboptimal response or intolerance to olanzapine in combination with a mood stabilizer because of its mood-stabilizing effect and minimal propensity for clinically significant body weight gain and metabolic disturbances. However, no study has evaluated the efficacy, safety, and tolerability of switching to ziprasidone from olanzapine in combination with a mood stabilizer for treatment of bipolar disorder. OBJECTIVE: The objective of this study was to evaluate the efficacy and safety of switching to ziprasidone in patients with bipolar I disorder experiencing a suboptimal response or intolerance to olanzapine in combination with lithium or valproate. METHODS: An 8-week, prospective, open-label study was conducted among inpatients and outpatients with bipolar I disorder who were taking olanzapine combined with lithium or valproate to treat recent manic or mixed episodes. In subjects experiencing a suboptimal response [≥16 points on the Young Mania Rating Scale (YMRS) at screening and baseline] or intolerance, olanzapine was switched to ziprasidone while maintaining the same dose of their current combined mood stabilizer during the 8-week trial. The primary efficacy measure was the mean change in the YMRS total score. Metabolic parameters were measured to evaluate the improvement in metabolic syndrome. RESULTS: A total of 56 patients were enrolled, and 46 (82.1 %) completed this study. Switching to ziprasidone was effective and well-tolerated. YMRS total scores were significantly reduced over 8 weeks (mean change, -10.4 ± 10.2). There were significant improvements in metabolic parameters, with mean changes of -0.4 ± 0.8 kg/m(2) in body mass index (BMI), -1.2 ± 2.5 kg in body weight, -21.3 ± 62.7 mg/dL in the fasting triglyceride level, and -13.2 ± 26.6 mg/dL in the total cholesterol level. Greater improvements in BMI, body weight, and dyslipidemia were positively correlated with a higher baseline BMI and abnormal lipid profile. CONCLUSIONS: Ziprasidone appears to be a good switching option for patients with bipolar I disorder experiencing suboptimal response or intolerance with olanzapine in combination with lithium or valproate. In addition, switching to ziprasidone improves metabolic parameters, especially in patients experiencing weight gain or dyslipidemia with olanzapine treatment.

Novelty-seeking among schizophrenia patients with comorbid alcohol abuse.

Since characterological characteristics of patients with schizophrenia and comorbid alcohol abuse are not well established, we compared outpatients with DSM-IV schizophrenia, with (n = 51) and without alcohol-abuse (n = 51), matched for sex, age, IQ, and symptom severity, using the Temperament and Character Inventory. Dual-diagnosis patients showed highly selective greater novelty seeking.
