Abstract: This manuscript summarizes specific issues in the disease course and pharmacological treatment of women with bipolar disorders. Gender differences relevant to the female biology manifest in symptoms, outcome, and course. The preponderance of depressive symptoms is typical, and the risk of rapid cycling is estimated to be eight times higher for women than for men. Comorbid anxiety and eating disorders occur more frequently in female patients. In planning treatment it is important to take fertility, contraception, and pregnancy into consideration and adjust the pharmacotherapy to harmonize with the patient's current phase of life. Little is known about potential sexual dysfunctions of bipolar women. Further research should include clinical and observational studies focusing on gender-specific differences in symptomatology, treatment, and long-term outcome of bipolar disorders.

Abstract: For now more than 50 years, lithium has been the gold standard for the pharmacologic treatment of bipolar disorder. However, its utility is not restricted to acute mania and prophylactic treatment of bipolar disorder. A relatively new indication for its use is the addition to an antidepressant in the acute treatment phase of unipolar major depression. To date, this treatment approach called lithium augmentation is the best-documented approach in the treatment of refractory depression. In international treatment guidelines and algorithms, lithium augmentation is considered a first-line treatment strategy for patients with a major depressive episode who do not adequately respond to standard antidepressant treatment. In a recent double-blind, placebo-controlled trial, lithium augmentation has demonstrated to also be effective in the continuation treatment phase to prevent early relapses. From animal studies there is robust evidence that lithium augmentation increases serotonin (5-HT) neurotransmission, possibly by a synergistic action of lithium and the antidepressant on brain 5-HT pathways. In contrast to the established decline of HPA system activity during treatment with tricyclic antidepressants, neuroendocrine studies on the effects of lithium augmentation on the HPA system showed an unexpected and marked increase in the ACTH and cortisol response in the combined DEX/CRH test. Here we review new data on the efficacy and mechanism of action of lithium augmentation.

Abstract: OBJECTIVE: Many researchers have analyzed seasonal variation in hospital admissions for bipolar disorder with inconsistent results. We investigated if a seasonal pattern was present in daily self-reported daily mood ratings from patients living in five climate zones in the northern and southern hemispheres. We also investigated the influence of latitude and seasonal climate variables on mood. METHOD: 360 patients who were receiving treatment as usual recorded mood daily (59,422 total days of data). Both the percentage of days depressed and hypomanic/manic, and the episodes of depression and mania were determined. The observations were provided by patients from different geographic locations in North and South America, Europe and Australia. These data were analyzed for seasonality by climate zone using both a sinusoidal regression and the Gini index. Additionally, the influence of latitude and climate variables on mood was estimated using generalized linear models for each season and month. RESULTS: No seasonality was found in any climate zone by either method. In spite of vastly different weather, neither latitude nor climate variables were associated with mood by season or month. CONCLUSION: Daily self-reported mood ratings of most patients with bipolar disorder did not show a seasonal pattern. Neither climate nor latitude has a primary influence on the daily mood changes of most patients receiving medication for bipolar disorder.

Abstract: OBJECTIVE: This study investigated the frequency of episodes and subsyndromal symptoms based on employment status in patients with bipolar disorder. METHODS: Patients with bipolar disorder (n = 281) provided daily self-reported mood ratings for 5 months, returning 46,292 days of data. Data were analyzed using three employment status groups: disabled (n = 75), full-time employee or full-time student (n = 135), and other (n = 71). Demographic characteristics were compared by employment status. A univariate general linear model with employment status and other demographic variables as fixed factors and covariates was used to analyze the percent of days in episodes and percent of days with subsyndromal symptoms. RESULTS: While there was no significant difference in the percent of days in episodes among the employment groups, disabled patients suffered subsyndromal symptoms of depression twice as frequently as those in the full-time group. Disabled patients spent 15% more days either in episodes or with subsyndromal symptoms than those in the full-time group, equivalent to about 45 extra sick days a year. CONCLUSION: Frequent subsyndromal symptoms, especially depressive, may preclude full-time responsibilities outside the home and contribute to disability in bipolar disorder. Additional treatments to reduce the frequency of subsyndromal symptoms are needed.

Abstract: BACKGROUND: Rapid-cycling bipolar disorder is often characterized by a lack of response to psychopharmacological treatment, and a standard therapy has not been developed yet. The aim of this study was to examine the long-term efficacy and safety of a monotherapy with quetiapine or sodium valproate (VPA) in patients with rapid-cycling bipolar disorder. METHODS: This open-label, randomized, parallel group monotherapy pilot study was conducted at 3 German centers. A sample of 38 remitted or partly remitted patients with bipolar disorder and rapid cycling (quetiapine n = 22; VPA n = 16) were treated with quetiapine or VPA (flexible dose design) for 12 months. RESULTS: Forty-one percent of the patients with quetiapine and 50% with VPA completed the trial. On the basis of ITT-LOCF, Life Chart Method data showed that patients being treated with quetiapine had significantly less moderate to severe depressive days than patients on VPA (mean +/- SD, 11.7 +/- 16.9 days vs 27.7 +/- 24.9 days; P = 0.04) while they did not differ in the number of days with manic or hypomanic symptoms. Furthermore, according to the Clinical Global Impression Scale, bipolar version, the responder rates tended to be higher for quetiapine than for VPA. There were no differences found evaluating the Hamilton Depression Rating Scale, the Montgomery-Asberg Depression Scale, and the Young Mania Rating Scale. The incidence of adverse events, especially of orthostatic dysregulation, sedation, and weight gain, was significantly higher in the quetiapine group. CONCLUSIONS: In this study, quetiapine was more effective than VPA on the number of depressive days and similar to VPA in the treatment of manic symptoms. Quetiapine was associated with a greater incidence of side effects, particularly orthostatic dysregulation, sedation, and weight gain.

Abstract: With the widespread recognition of the value of active patient participation in their care, ChronoRecord software was developed to automate daily self-reporting by patients with bipolar disorder. A prior study demonstrated concurrent validity between self-ratings on ChronoRecord and clinician ratings on the Hamilton Depression Rating Scale (HAMD), but validity with the Young Mania Rating Scale (YMRS) could not be shown due to a lack of data when the outpatients were manic (Bauer et al., Bipolar Disorders 6, 67-74, 2004). This study expanded upon the prior validation study to include inpatients with mania. Self-reported mood ratings on ChronoRecord and clinician ratings on the YMRS were obtained on the same day from 27 inpatients (57 ratings); these data were also combined with the ratings from the 80 outpatients (total 107 patients, 340 ratings). Using Pearson correlation, the self-reported ratings on ChronoRecord were significantly correlated with the YMRS. The accuracy of ChronoRecord to discriminate hypomania and mania was high, as described by the area under the receiver operating characteristic curve. Post-hoc analysis of the level of agreement between ChronoRecord and YMRS ratings was excellent or good in all cases using the kappa statistic. These data demonstrate concurrent validity between ChronoRecord and YMRS.

Abstract: OBJECTIVE: Patients with bipolar disorder often report depressive symptoms that do not meet the DSM-IV criteria for an episode. Using daily self-reported mood ratings, we studied how changing the length requirement to that typical of recurrent brief depression (2-4 days) would impact the number of depressed episodes. METHOD: 203 patients (135 bipolar I and 68 bipolar II by DSM-IV criteria) recorded mood daily using ChronoRecord software on a home computer (30,348 total days; mean 150 days). Episodes of depression and days of depression outside of episodes were determined. Symptom intensity (mild versus moderate or severe) was investigated within and outside of depressive episodes. RESULTS: Decreasing the minimum duration criterion for an episode of depression to 2 days increased the number of patients with a depressed episode two and a half times (52 to 131), and quadrupled both the number of depressed episodes per patient (0.62 to 2.88) and the number of depressed episodes for all patients (125 to 584). With a 2-day episode length, 34% of days of depression remained outside an episode. The ratio of days with severe symptoms within episodes remained consistent (about 25%) in spite of decreasing the episode length to 2 days. Considering only days with severe symptoms, about 25% remained outside of episodes even with a 2-day length. None of the results distinguished bipolar I from bipolar II disorder. LIMITATIONS: Self-reported data, computer access required, relatively short study length, no control group. CONCLUSION: Brief depressive episodes and single days of depression outside of episodes occur frequently in both bipolar I and bipolar II disorder. Moderate or severe symptoms occur during brief episodes at a ratio similar to that for episodes that meet the DSM-IV criteria.

Abstract: Finding predictors of the response to antidepressant therapy is a major goal of molecular psychiatry. The genes encoding the serotonin (SERT) and dopamine (DAT1) transporters are among the possible candidate genes modulating an individual's antidepressant response. In a naturalistic prospective cohort study with a total of 190 fully assessed patients, improvement of depression symptoms during the 3 weeks following initiation of antidepressant therapy was recorded using the 21-item Hamilton Depression Rating Scale (HDRS). The SLC6A3 3' UTR 40-bp variable number of tandem repeats (VNTR) and the SLC6A4 5' 44-bp insertion/deletion polymorphism were analyzed by polymerase chain reaction. There was a significantly smaller number of rapid responders among homozygous carriers of the DAT1 9-repeat allele (9/9) than among heterozygous (9/10) and homozygous (10/10) carriers of the 10-repeat allele (19 versus 37 versus 52%, respectively, P=0.0037). Median decline in HDRS score was 35, 40, and 52% in patients with the 9/9, 9/10, and 10/10 genotypes, respectively (P=0.013). The effect was found in all classes of medications (selective serotonin reuptake inhibitors (SSRIs), tricyclics, mirtazapine, venlafaxine) and statistically significant also within the subgroup of patients having received SSRIs. The serotonin promoter insertion/deletion genotype had no effect in the entire study group, but there was an insignificant trend of better response in the l/l and l/s carriers who received SSRIs or mirtazapine. In conclusion, the dopamine transporter VNTR polymorphism influenced rapid response to antidepressant therapy. Compared with homozygous carriers of the 10-repeat allele, carriers of the 9/10 genotype had an odds ratio (OR) calculated by logistic regression analysis of 1.6 (95% CI 0.8-3.2) and carriers of the 9/9 genotype had an OR of 6.0 (1.5-24.4) for no or poor response. Further studies are required to confirm this clinical association and to elucidate the underlying mechanisms.

Abstract: BACKGROUND: This prospective study was designed to determine whether patients with prophylaxis-resistant affective disorders, receiving adjunctive maintenance therapy with supraphysiological doses of levothyroxine (L-T4), show evidence of accelerated bone loss compared to the reference population database. METHODS: In 21 patients, bone mineral density (BMD) of the spine (lumbar vertebrae L1-L4) and femur (femoral neck, trochanter, and Ward's triangle) was measured by dual energy X-ray absorptiometry (DXA). BMD measurement was performed first after patients had been on thyroid-stimulating hormone (TSH)-suppressive therapy with L-T4 (mean dose=411 mcg/d) for an average of 16.4 months and again after 33.6 months of L-T4 (mean dose=416 mcg/d) therapy. RESULTS: There was no statistically significant difference between the actual percentage decline in bone mineral density and the expected percentage decline in any of the measured bone regions. In a stepwise linear regression analysis, age was identified as a predictor of percentage change in BMD. After controlling for age, the only other variable that showed a consistent trend was the dose of L-T4, with higher doses being positively correlated with the percentage decline of BMD. LIMITATIONS: Relatively small sample size, no bone density assessment prior to treatment with L-T4, no patient control group with mood disorders who did not receive L-T4 treatment, and bone density follow-up intervals were variable. CONCLUSIONS: This study did not demonstrate evidence that long-term treatment of affectively ill patients with supraphysiological doses of L-T4 significantly accelerates loss of bone mineral density compared to the age-matched reference population. However, the decline of BMD in one individual patient underscores that caution is indicated and that regular assessment of BMD during longer-term supraphysiological thyroid hormone treatment is needed.

Abstract: Bipolar disorders are often diagnosed too late with an average of ten years elapsing between the first disease episode and the correct diagnosis and treatment. The most common misdiagnoses are unipolar depression, schizophrenia and ADHD (Attention Deficit Hyperactivity Disorder). The suicide rate associated with bipolar disease is very high. Treatment consists in the administration of mood stabilizers, in the first instance lithium, but also atypical neuroleptics or lamotrigine. In the depressive phase, additional antidepressants or lamotrigine, in the manic phase valproate or an antipsychotic agent may be needed. Medication must be continued unchanged for several months beyond acute treatment. The subsequent relapse prophylaxis depends on effectiveness, tolerability, comorbidity, suicidal risk and compliance. Pharmacotherapy is supplemented by psychotherapy and psycho-education.
