Occurrence of bipolar spectrum disorder and comorbidities in women with eating disorders

Background Eating disorder (ED) patients often have comorbidities with other psychiatric disorders, especially with mood disorders. Although recent studies suggest an intimate relationship between ED and bipolar disorder (BD), the study on a broader bipolar spectrum definition has not been done in this population. We aimed to study the occurrence of bipolar spectrum (BS) and...

Antidepressant dosage taken by patients with bipolar disorder: factors associated with irregularity

Background This study analyzed regularity in the daily dosage of antidepressants taken by patients with bipolar disorder and identified the factors associated with irregularity. Methods Daily self-reported medication dosage taken and mood ratings were available from 144 patients who received treatment as usual. All 144 patients took the same antidepressant for at least 100 days...

Behavioral addictions in euthymic patients with bipolar I disorder: a comparison to controls

Background Bipolar disorder may be associated with a hypersensitive behavioral approach system and therefore to increased reward sensitivity. The objective of this study is to explore the interrelationships between bipolar disorder, behavioral addictions, and personality/temperament traits in a group of euthymic outpatients with bipolar I disorder and in a group of comparison...

Quantitative leukocyte BDNF promoter methylation analysis in bipolar disorder

Background Bipolar disorder (BD) is a complex psychiatric phenotype with a high heritability and a multifactorial etiology. Multisite collaborative efforts using genome-wide association studies (GWAS) have identified only a portion of DNA sequence-based risk factors in BD. In addition to predisposing DNA sequence variants, epigenetic misregulation may play an etiological role in...

Evaluating depressive symptoms in hypomanic and manic episodes using a structured diagnostic tool: validation of a new Mini International Neuropsychiatric Interview (M.I.N.I.) module for the DSM-5 'With Mixed Features’ specifier

BackgroundThe Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5), includes a new 'With Mixed Features’ specifier for mood episodes. In (hypo-)manic episodes, the specifier is given if three or more depressive symptoms are present nearly every day during the episode. A new module of the Mini International Neuropsychiatric Interview (M.I.N.I.) has been...

Hypercalcemia in patients with bipolar disorder treated with lithium: a cross-sectional study

BackgroundLithium-induced hyperparathyroidism (LIH) is a relative underrecognized complication of long-term lithium treatment. Hypercalcemia may be the first, but often overlooked, sign of LIH. Symptoms of LIH can be similar to the underlying psychiatric illness, which may cause a significant doctor’s delay in diagnosing LIH. The aim of this study was to determine the prevalence...

Impulsivity, anxiety, and alcohol misuse in bipolar disorder comorbid with eating disorders

Background Eating disorders (ED) are noted to occur with bipolar disorder (BD), but relationships between additional comorbidities, clinical correlates, and personality factors common to both remain largely unknown. Methods Using data from the Prechter Longitudinal Study of Bipolar Disorder, we measured the prevalence and demographic factors of comorbid ED with BD, presence of...

Stability of lithium treatment in bipolar disorder - long-term follow-up of 346 patients

Background The purpose of this study was to investigate the effectiveness and stability of long-term lithium treatment in a prospective, international, multicenter cohort of bipolar patients in a naturalistic setting. Methods Patients were selected according to DSM IV criteria for bipolar disorder and required long-term treatment. They were prospectively followed and documented...

Quetiapine monotherapy in bipolar II depression: combined data from four large, randomized studies

Background Despite being present in up to 1% of the population, few controlled trials have examined the efficacy of treatments for bipolar II depression. Pooled data are presented from four placebo-controlled studies (BOLDER I [5077US/0049] and II [D1447C00135]; EMBOLDEN I [D1447C00001] and II [D1447C00134]) that evaluated the efficacy of quetiapine monotherapy for depressive...

Bipolar disorder and socioeconomic status: what is the nature of this relationship?

Background In psychiatric literature stretching over a century, there have been glaring discrepancies in the findings describing the relationship between bipolar disorder (BD) and socioeconomic status (SES). Early studies indicated an overall association between manic-depressive illness and higher social class. However, recent epidemiologic studies have failed to find an...

The association of glycogen synthase kinase-3beta (GSK-3β) gene polymorphism with kidney function in long-term lithium-treated bipolar patients

Background Most bipolar patients experience a reduction in urinary concentrating ability within a few weeks of starting lithium treatment. This phenomenon may be connected with the effect of lithium on the glycogen synthase kinase-3beta (GSK-3β) present in the renal tubules. The GSK-3β gene is located on chromosome 3q13 and possesses a functional -50 C/T polymorphism. In the...

Do current screening recommendations allow for early detection of lithium-induced hyperparathyroidism in patients with bipolar disorder?

Background Current screening recommendations for early detection of lithium-associated hyperparathyroidism propose an exclusive measurement of serum albumin-adjusted calcium (Aac) concentration as a single first step. However, longitudinal data in patients with recurrent affective disorders suggest that increases in serum intact parathyroid hormone (iPTH) levels in lithium...

Biological rhythm disturbance in remitted bipolar patients

Background Biological rhythm disturbance is common in bipolar patients and seems to affect the course and prognosis of the illness negatively. The main aim of the current study was to assess biological rhythms in remitted bipolar patients. We also assessed whether there was an association between clinical variables or functioning and biological rhythms in remitted bipolar...

European Network of Bipolar Research Expert Centre (ENBREC): a network to foster research and promote innovative care

Bipolar disorders rank as one of the most disabling illnesses in working age adults worldwide. Despite this, the quality of care offered to patients with this disorder is suboptimal, largely due to limitations in our understanding of the pathology. Improving this scenario requires the development of a critical mass of expertise and multicentre collaborative projects. Within the...

Aripiprazole as augmentation therapy in bipolar patients with current minor or subsyndromal mood symptoms

Background This study aims to evaluate the effectiveness of aripiprazole augmentation of maintenance treatment for bipolar disorder in patients with minor or subsyndromal mood episodes while on a stable dose of a mood stabiliser and/or antidepressant. Methods All subjects had a diagnosis of bipolar I or II disorder (Diagnostic and Statistical Manual of Mental Disorders-4th...

Drug treatment patterns in bipolar disorder: analysis of long-term self-reported data

BackgroundThe objective of this study is to investigate drug treatment patterns in bipolar disorder using daily data from patients who received treatment as usual.MethodsPatients self-reported the drugs taken daily for about 6 months. Daily drug use and drug combinations were determined for each patient, both by the specific drugs and by medication class. The drug load was...

Cortical thinning in young psychosis and bipolar patients correlate with common neurocognitive deficits

BackgroundPeople in midlife with established psychosis or bipolar disorder exhibit patterns of cortical thinning across several brain regions. It is unclear whether these patterns are indicative of a continuously active pathological process, residual effects of an earlier illness phase or pre-illness onset developmental risk factors. Here, we investigated whether cortical...
