- Background: Low levels of plasma apolipoprotein E (apoE) and presence of the APOE epsilon 4 allele are associated with an increased risk of Alzheimer's disease (AD). Although the increased risk of AD in APOE epsilon 4-carriers is well-established, the protein levels have received limited attention. Methods: We here report the total plasma apoE and apoE isoform levels at baseline from a longitudinally (24 months) followed cohort including controls (n = 3 9), patients with stable amnestic mild cognitive impairment during 24 months follow up (MCI-MCI, n = 3 0) , patients with amnestic MCI (aMCI) that during follow-up were clinically diagnosed with AD with dementia (ADD) (MCI-ADD, n = 28), and patients with AD with dementia (ADD) at baseline (ADD, n = 28). We furthermore assessed associations between plasma apoE levels with cerebrospinal fluid (CSF) AD biomarkers and alpha-synuclein, as well as both CSF and plasma neurofilament light chain (NfL), YKL-40 and kallikrein 6. Results: Irrespective of clinical diagnosis, the highest versus the lowest apoE levels were found in APOE epsilon 2/epsilon 3 versus APOE epsilon 4/epsilon 4 subjects, with the most prominent differences exhibited in females. Total plasma apoE levels were 32% and 21% higher in the controls versus MCI-ADD and ADD patients, respectively. Interestingly, MCI-ADD patients exhibited a 30% reduction in plasma apoE compared to MCI-MCI patients. This decrease appeared to be associated with brain amyloid-beta (A beta(42)) pathology regardless of disease status as assessed using the Amyloid, Tau, and Neurodegeneration (A/T/N) classification. In addition to the association between low plasma apoE and low levels of CSF A beta(42), lower apoE levels were also related to higher levels of CSF total tau (t-tau) and tau phosphorylated at Threonine 181 residue (p-tau) and NfL as well as a worse performance on the mini-mental-state-examination. In MCI-ADD patients, low levels of plasma apoE were associated with higher levels of CSF alpha-synuclein and kallikrein 6. No significant correlations between plasma apoE and the astrocytic inflammatory marker YKL40 were observed. Conclusions: Our results demonstrate important associations between low plasma apoE levels, A beta pathology, and progression from aMCI to a clinical ADD diagnosis.
