Immunomodulatory treatment may change functional and structural brain imaging in severe mental disorders.

Neuroinflammation has been implicated in the pathophysiology of schizophrenia and obsessive-compulsive disorder (OCD) and deviations in brain structure and connectivity are seen in these disorders. Here, we explore the effects of a potent immunomodulatory treatment on neuroimaging. In a pilot study of rituximab treatment in schizophrenia and OCD, a subgroup (n = 13) underwent structural and functional magnetic resonance imaging before and 5 months after treatment, to study longitudinal changes in resting-state functional connectivity (rsFC) and voxel-based morphometry (VBM).

Study protocol for a randomized controlled trial with rituximab for psychotic disorder in adults (RCT-Rits).

Background: The role of inflammation in the aetiology of schizophrenia has gained wide attention and research on the association shows an exponential growth in the last 15 years. Autoimmune diseases and severe infections are risk factors for the later development of schizophrenia, elevated inflammatory markers in childhood or adolescence are associated with a greater risk of schizophrenia in adulthood, individuals with schizophrenia have increased levels of pro-inflammatory cytokines compared to healthy controls, and autoimmune diseases are overrepresented in schizophrenia. However, treatments with anti-inflammatory agents are so far of doubtful clinical relevance.

Incidence of Venous Thromboembolism Among Commonly Prescribed Second-Generation Antipsychotics.

Second-generation antipsychotics (SGAs) are commonly prescribed medications used to treat a variety of mental health conditions. Recent data has correlated antipsychotic medications with venous thromboembolism (VTE). SGAs have diverse side effect profiles, which may contribute to differences in incidence of VTE.
