Objective Serum lipid levels may be associated with the affective severity of bipolar disorder, but data on lipid profiles in Asian patients with bipolar disorder and the lipid alterations in different states of opposite polarities are scant. We investigated the lipid profiles of patients in the acute affective, partial, and full remission state in bipolar mania and depression. Methods The physically healthy patients aged between 18 and 45 years with bipolar I disorder, as well as age-matched healthy normal controls were enrolled. We compared the fasting blood levels of glucose, cholesterol, triglyceride, low-density lipoprotein, and high-density lipoprotein of manic or depressed patients in the acute phase and subsequent partial and full remission with those of their normal controls. Results A total of 32 bipolar manic patients (12 women and 20 men), 32 bipolar depressed participants (18 women and 14 men), and 64 healthy control participants took part in this study. The mean cholesterol level in acute mania was significantly lower than that in acute depression (p < 0.025). The lowest rate of dyslipidemia (hypertriglyceridemia or low high-density lipoprotein cholesterol) was observed in acute bipolar mania. Conclusion Circulating lipid profiles may be easily affected by affective states. The acute manic state may be accompanied by state-dependent lower cholesterol and triglyceride levels relative to that in other mood states. [ABSTRACT FROM AUTHOR]

Patients with major depression have greater suicide mortality, but there is no data on the standardised mortality ratio (SMR) and factors for suicide of major depression for Asian countries. This research estimates the SMR and the risk and protective factors for suicide mortality in patients with major depression in a large-scale Asian cohort. Patients with major depression (N = 1978) admitted to a psychiatric hospital in Taiwan between 1985 and 2008 were enrolled as the study cohort. When the cohort was linked to the national mortality database, 415 deceased patients were identified. Of these 415 deaths, 107 were from suicide. Nested case–control with risk sampling was used, where each case was matched with two controls. Clinical information was collected through a standardised chart review process. The SMR for suicide mortality was estimated, and a conditional logistic regression analysis was performed to determine risk and protective factors for suicide. Patients with major depression had high all-cause and suicide mortality, with SMRs of 3.9 and 35.4, respectively. Agitation (adjusted risk ratio [aRR] = 2.85, P = 0.058), restlessness (aRR = 15.05, P = 0.045) and previous suicide attempts (aRR = 4.48, P = 0.004) were identified as risk factors for suicide mortality. By contrast, those with employment (aRR = 0.15, P = 0.003) or loss of interest (aRR = 0.32, P = 0.04) had lower risk. Patients with depression exhibited higher suicide mortality. Clinical staff should pay close attention to risk and protective factors to reduce suicide risk. • People with major depressive disorder have an excessively high mortality rate, especially from suicide. • Our findings suggest two protective factors against suicide, i.e., employment and loss of energy during depression. • Clinicians should pay attention for risk factors of suicide, i.e., previous suicide attempts, agitation and restlessness.

Objective Coronary heart disease (CHD) remains the principal cause of excessive natural deaths in bipolar patients; however, electrocardiogram analyses and clinical features predicting CHDs in elderly bipolar patients remain limited. We sought to examine the relationship between CHDs, as determined by electrocardiogram, and clinical characteristics. Methods We recruited bipolar I outpatients Diagnostic Statistical Manual of Mental Health (DSM-IV) who were more than 60 years old and had at least one psychiatric admission. Subjects were divided into two groups based on the presence or absence of CHD diagnosed by electrocardiogram analysis at entry of study. Clinical data were obtained by a combination of interviewing patients and family members and retrospectively reviewing medical records of the most recent acute psychiatric hospitalization. Results Eighty patients with bipolar disorder were enrolled. A total of 20 (25%) in the study had CHDs. The mean age at the time of entry into study was 67.6 ± 5.5 years old in group with CHD and 66.8 ± 6.8 years old in that without CHD. Among the clinical characteristics examined, higher mean levels of serum sodium and thyroxine during the acute affective phase as well as more first-degree family history with bipolar disorder were related to having CHD, particularly the serum sodium level. Conclusions About one fourth of old bipolar patients have CHDs in both Asian and Western populations. Aging patients with bipolar disorder may have unique clinical factors (e.g., hypernatremia or elevated thyroxine) related CHDs that could warrant special attention in their psychiatric and medical care to minimize cardiovascular disease and mortality.
