The aim of this study, therefore, was to compare the immunomodulatory effects of intravenous (IVIg) and subcutaneous immunoglobulin (SCIg) in patients with CIDP and in IVIg\u2010treated common variable immunodeficiency (CVID) patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Serum and peripheral blood mononuclear cell samples were obtained from 30 CIDP patients receiving IVIg, 10 CIDP patients receiving SCIg, and 15 patients with CVID receiving IVIg. Samples and clinical data were obtained prior to IVIg\/SCIg and at 3\u2009days, 7\u2009days, and, in CIDP patients receiving IVIg, 21\u2009days post\u2010administration. Serum cytokines were assessed by Luminex\u2010based multiplex assay and enzyme\u2010linked immunosorbent assay. Immune cells were characterized by flow cytometry.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Immune cell profiles of CIDP and CVID patients differed in frequencies of myeloid dendritic cells and cytotoxic natural killer cells. During treatment with IVIg or SCIg in CIDP patients, cellular immunomarkers were largely similar. CIDP patients receiving IVIg had higher macrophage inflammatory protein (MIP)\u20101\u03b1 (<jats:italic>p<\/jats:italic>\u2009=\u20090.01), interleukin (IL)\u20104 (<jats:italic>p<\/jats:italic>\u2009=\u20090.04), and IL\u201033 (<jats:italic>p<\/jats:italic>\u2009=\u20090.04) levels than SCIg recipients. IVIg treatment more broadly modulated cytokines in CIDP than SCIg treatment.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Our study demonstrates that the modulation of cellular immunomarkers in CIDP is independent of the application route of therapeutic immunoglobulin.
