Use of antidepressants and benzodiazepine-related hypnotics before and after initiation of TNF-α inhibitors or non-biological systemic treatment in patients with rheumatoid arthritis, psoriatic arthritis or ankylosing spondylitis.

Background: Rheumatoid arthritis (RA), psoriatic arthritis (PsA) and ankylosing spondylitis (AS) are autoimmune disorders associated with an increased risk for depression, anxiety and sleeping problems. The objective of this study was to analyze use of antidepressants and benzodiazepine-related hypnotics (BRH) in Sweden before and after first time treatment with anti-TNF and non-biological systemic (NBS) treatments among patients with the above diagnoses, and to correlate such use with that of randomly selected population controls.

Methods: Patients and dispensed drugs were identified in nationwide Swedish healthcare registers.

Monotherapy vs. combination therapy for post mania maintenance treatment: A population based cohort study.

In recent years, the use of atypical antipsychotics and combination therapy for relapse prevention in bipolar disorder has increased substantially. However, real-world data on the comparative effectiveness of these treatment options are largely non-existent. We conducted a population-based cohort study, using data from Swedish national registers.

Mortality in treatment-resistant unipolar depression: A register-based cohort study in Sweden.

Background: The impact of treatment resistant depression (TRD) on mortality is not established.

Methods: Using Swedish national registers, 118,774 patients between 18-69 years of age who had been prescribed an antidepressant and been diagnosed with depression in specialized care were identified. Patients with at least two additional treatment trials during the same depressive episode were classified as having TRD.
