This result implies that PBMCs' TNF mRNA expression might be potentially considered as a prognostic biomarker of ocrelizumab effectiveness in MS patients. However, further studies comprising large cohorts and additional immunological parameters are warranted.
This study provides insight into unique biomarker profile in patients on ocrelizumab. Increased BAFF was associated with lower IgG and IgA levels, biomarkers of neuroaxonal damage and inflammation in MS patients without recent acute inflammatory activity on ocrelizumab.
