Abstract
Background
Growing evidence suggests an association between dyslipidemia and autoimmune diseases. This study aimed to perform a preliminary analysis to investigate the role of lipid profiles in anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis and to preliminarily explore the potential inflammatory effects of lipids on this disease by analyzing the association of lipid profiles with different inflammatory markers.
Methods
This retrospective study consisted of 40 anti-NMDAR encephalitis patients and 74 healthy controls. Serum lipid profiles and different inflammatory markers were analyzed upon admission and at each follow-up. Lipid profiles were compared among subgroups of patients, which were divided according to clinical characteristics. Correlations between lipid profiles and different inflammatory markers were assessed.
Results
The results showed that lipid profiles were abnormal and were correlated with both disease severity and prognosis in patients with anti-NMDAR encephalitis. Correlations between lipid profiles and different inflammatory markers were observed. After 12 months of treatment, inflammatory markers changed with lipid profiles, and these changes were significantly correlated.
Conclusions
Lipid profiles are associated with pathogenesis and progression of anti-NMDAR encephalitis, and they are significantly correlated with different inflammatory markers, suggesting that the association of lipids with the disease might be influenced by the inflammatory response.
