Mendelian randomization analyses support causal relationships between systemic lupus erythematosus and brain imaging-derived phenotypes.

ABSTRACT:

Background

Neuropsychiatric disorders in systemic lupus erythematosus (NPSLE) are often accompanied by alterations in brain structure and function. Subtle changes in brain structure also can be observed in non-NPSLE patients. MRI can be used as a non-invasive tool to determine nervous system involvement in SLE. However, the causal relationship between SLE and brain MRI remains unclear.

Methods

We designed two-sample MR analyses to identify brain IDPs associated with SLE. The GWAS summary data of 3,935 IDPs from the UK Biobank were used as outcomes in MR analyses.

Results

There were 25 statistically significant causal relationships between SLE and brain IDPs, in which the several cortical area, anterior corona radiata, and posterior limb of internal capsule were includ
