Gluten sensitivity and relationship to psychiatric symptoms in people with schizophrenia.

The relationship between gluten sensitivity and schizophrenia has been of increasing interest and novel mechanisms explaining this relationship continue to be described. Our study in 100 people with schizophrenia compared to 100 matched controls replicates a higher prevalence of gluten sensitivity and higher mean antigliadin IgG antibody levels schizophrenia (2.9 ± 7.

Analytical and clinical comparison of two fully automated immunoassay systems for the diagnosis of celiac disease.

Objective: Here we compared analytical and clinical performance characteristics of two novel automated assay systems for the detection of celiac disease (CD) specific antibodies: QUANTA Flash (INOVA Diagnostics, Inc.) and EliA (Thermo Scientific).

Methods: A total of 74 biopsy-proven CD patients (2 with IgA deficiency) and 138 controls were tested by both methods.

Relationships between serum leptin level and severity of positive symptoms in schizophrenia.

The adipocytokine leptin is a key mediator of energy homeostasis. Recent papers have suggested that leptin may also have roles in the brain however it is unclear whether leptin is connected to symptoms of mental disorders. In this study, we sought to clarify the relationships between serum leptin level and psychopathology in schizophrenia (SZ) patients.

Increased prevalence of transglutaminase 6 antibodies in sera from schizophrenia patients.

Gluten can cause extraintestinal manifestations with or without gastrointestinal symptoms and elevated antitissue transglutaminase 2 (tTG2) autoantibodies. Organ-specific gluten reaction involves immune response toward other transglutaminase (TG) isoforms including tTG3 (expressed in the skin, leading to dermatitis herpetiformis) and tTG6 (expressed in the brain, causing gluten ataxia). This analysis focuses on tTG6 antibodies, which have never been studied before in schizophrenia (SZ) and its relationships to tTG2 and to antigliadin antibodies.
