Association between peripheral activated naive and double negative 2 B-cell subsets and clinical parameters in lupus nephritis patients.

ABSTRACT: Altered composition of B-cell compartments is a known feature in patients with systemic lupus erythematosus (SLE). However, deep characterisation of B-cell subsets and their relation to clinical manifestations and disease activity in patients is limited. In this study, we analysed peripheral B-cell subsets phenotype in SLE (n = 35) and healthy controls (HCs, n = 15) by spectral flow cytometry. Disease activity was stratified as inactive (SLEDAI-2 K score 0, n = 2), mild (SLEDAI-2 K score 1-5, n = 12), moderate (SLEDAI-2 K score 6-10, n = 6) or high (SLEDAI-2 K > 10, n = 15). An elevated proportion of activated naive (aNAV), double negative 2 (DN2) and plasmablasts (PB) was observed in patients with high disease activity, compared to other groups of patients and HCs.
