High Prevalence of aCL-IgA and aβ2GPI-IgA in Drug-Free Schizophrenia Patients: Evidence of a Potential Autoimmune Link.
Article in Antibodies (Basel, Switzerland), 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND/
objectivesSchizophrenia (SZ) is a complex psychiatric disorder with increasing evidence pointing to an autoimmune component, including the presence of antiphospholipid antibodies (aPLs). This study aims to assess the prevalence of anticardiolipin (aCL) and anti-beta-2 glycoprotein I (aβ2GPI) antibodies, particularly the IgG, IgA, and IgM isotypes, in drug-free SZ patients compared to healthy controls, and explore their possible involvement in the disease's pathophysiology.
methodsEighty SZ patients meeting DSM-IV criteria were recruited, along with 80 matched healthy controls. Serum samples were analyzed using enzyme-linked immunosorbent assays (ELISA) to quantify IgG, IgA, and IgM isotypes of aCL and aβ2GPI.
resultsSZ patients exhibited significantly higher levels of aCL-IgM and aCL-IgA (
conclusionsThis study is the first to report a high prevalence of aCL-IgA and aβ2GPI-IgA in SZ patients, highlighting a possible autoimmune involvement in the disease. The presence of multiple aPL isotypes, particularly IgA, suggests a need for further investigation into their role in SZ pathogenesis and their potential association with APS.
