The St. Göran project - a multi-pronged strategy for longitudinal studies for bipolar disorders.

Introduction: The St. Göran Bipolar Project (SBP) is a longitudinal outpatient study investigation aimed at identifying predictive factors associated with long-term outcomes in individuals with bipolar disorder. These outcomes include cognitive function, relapse rate, treatment responses, and functional outcomes.

Association between polarity of first episode and solar insolation in bipolar I disorder.

Objective: Circadian rhythm disruption is commonly observed in bipolar disorder (BD). Daylight is the most powerful signal to entrain the human circadian clock system. This exploratory study investigated if solar insolation at the onset location was associated with the polarity of the first episode of BD I.

[Bipolar disorder type 1 was the most stable bipolar subdiagnosis].

DSM-IV subcategorises bipolar disorders into type 1, type 2, and a third not otherwise specified (NOS) category. Although previous works suggest that these subtypes remain reasonably stable over time, it is unclear if subdiagnoses endure over time or if patients are commonly recategorized within the spectrum in a real-world clinical setting. We assessed subdiagnostic stability in 6,374 individuals with bipolar disorder using data from the Swedish national quality assurance register for bipolar disorders (BipoläR).

Regional lithium prescription rates and recurrence in bipolar disorder.

Background: Lithium is the best documented maintenance treatment in bipolar disorder, but its use varies considerably across and within countries. It is not known whether regional differences in lithium prescription rates translate to differing regional outcomes.

Aims: To estimate associations between county specific lithium prescription rates and county specific recurrence odds of bipolar disorder in Sweden.

Patient educational level and management of bipolar disorder.

Background: Socioeconomic factors can affect healthcare management.

Aims: The aim was to investigate if patient educational attainment is associated with management of bipolar disorder.

Method: We included patients with bipolar disorder type 1 (n = 4289), type 2 (n = 4020) and not otherwise specified (n = 1756), from the Swedish National Quality Register for Bipolar Disorder (BipoläR).

Lithium-Associated Hypercalcemia: Pathophysiology, Prevalence, Management.

Background: Lithium-associated hypercalcemia (LAH) is an ill-defined endocrinopathy. The aim of the present study was to determine the prevalence of hypercalcemia in a cohort of bipolar patients (BP) with and without concomitant lithium treatment and to study surgical outcomes for lithium-associated hyperparathyroidism.

Methods: Retrospective data, including laboratory results, surgical outcomes and medications, were collected from 313 BP treated with lithium from two psychiatric outpatient units in central Sweden.

Prevalences of autoimmune diseases in schizophrenia, bipolar I and II disorder, and controls.

Previous studies on the relationship between autoimmune diseases, schizophrenia, and bipolar disorder are mainly based on hospital discharge registers with insufficient coverage of outpatient data. Furthermore, data is scant on the prevalence of autoimmune diseases in bipolar subgroups. Here we estimate the self-reported prevalences of autoimmune diseases in schizophrenia, bipolar disorder type I and II, and controls.

[Prescribed drug use for bipolar disorder type I and II in clinical practice].

Prescribed drug use for bipolar disorder type I and II in clinical practice Practice guidelines based on available evidence and clinical consensus are available for the treatment of bipolar disorder. We surveyed to which extent those guidelines are implemented in clinical practice in Sweden. We analysed pharmacological treatment in patients with bipolar disorder in 2015 using the national quality register for bipolar disorder (BipoläR).

Changes in mood stabilizer prescription patterns in bipolar disorder.

Background: Lithium is a first line treatment option in bipolar disorder, but several alternative treatments have been introduced in recent years, such as antiepileptic and atypical antipsychotic drugs. Little is known about how this has changed the prescription patterns. We investigated possible changes in the use of mood stabilizers and antidepressants in Sweden during 2007-2013.

[Changes in prescription patterns to patients with bipolar syndromes. Increased use of lamotrigine and decreased use of lithium].

Lithium is a first line option in the maintenance treatment of bipolar disorder, but several alternative treatment regimens have been introduced in recent years, among them treatment with antiepileptic compounds and atypical antipsychotic drugs. Little is known about if and how this has changed the prescription patterns of mood stabilizers. We analysed trends in prescription of mood stabilisers in Sweden using the national quality register for bipolar disorder (BipoläR), the Prescribed Drug Register, and the Patient Register during the years 2007-2011.
