IL-8 as a potential biomarker in Guillain-Barre Syndrome.
This pilot study was designed to compare the levels of interleukin-8 (IL-8), a pro-inflammatory chemokine, in the cerebrospinal fluid (CSF) of patients with Guillain-Barre syndrome (GBS), chronic inflammatory demyelinating polyneuropathy (CIDP), non-inflammatory polyneuropathy (PNP), and other non-inflammatory neurological diseases (functional syndrome or migraine). The results show elevated CSF IL-8 levels in GBS compared to the other groups (p < 0.05). IL-8 could be considered a potential biomarker to differentiate GBS from CIDP. This distinction could be relevant in terms of therapeutic decisions and functional prognosis.

Serum cytokine patterns in immunoglobulin m monoclonal gammopathy-associated polyneuropathy.
Polyneuropathy with immunoglobulin M monoclonal gammopathy (IgM-PNP) is associated with the presence of IgM antibodies against nerve constituents such as myelin associated glycoprotein (MAG) and gangliosides.. To test whether B-cell-stimulating cytokines are increased in IgM-PNP, we measured serum concentrations of 11 cytokines in 81 patients with IgM-PNP and 113 controls.. Median interleukin (IL)-6 concentrations were higher in patients with IgM-PNP, and median IL-10 concentrations were higher in the subgroup with anti-MAG IgM antibodies. These serum concentrations were not increased in 110 patients with multifocal motor neuropathy.. Median IL-6 and IL-10 serum concentrations differ between patients with anti-MAG neuropathy and other patients with IgM-PNP compared with healthy and neuropathy controls. These differences may indicate differences in immune-mediated disease mechanisms. Muscle Nerve 59:694-698, 2019.

The expression pattern of inflammatory mediators in cerebrospinal fluid differentiates Guillain-Barré syndrome from chronic inflammatory demyelinating polyneuropathy.
Guillain-Barré syndrome (GBS) and chronic inflammatory demyelinating polyneuropathy (CIDP) share histopathological features but display different disease courses; we measured the concentration of 50 inflammatory mediators in the cerebrospinal fluid (CSF) of patients with either of these diseases.. CSF samples were collected during a diagnostic lumbar puncture and stored at -30 degrees C. We analyzed the CSF of nine subjects with GBS; eight with CIDP; eight with diabetic polyneuropathy (DP) and seven with headache (controls). Fifty inflammatory mediators were simultaneously measured with a multiplex bead-based ELISA on a Suspension Array System. After Bonferroni's correction for repeated measures, non-parametric variance and post hoc test were calculated.. Thirty-two inflammatory mediators were expressed. The median concentration of IL-6, IL-9, IL-15, IL-18, CCL4, CXCL1, LIF, MIF, PDGFbb, IFN-gamma2, IL-2ra, IL-12(p40), IL-16, SCGF-b, TRAIL, FGF, G-CSF, GM-CSF, and M-CSF was not different among groups (variance: n.s.). The median concentration of CCL2, CCL7, CCL27, CXCL9, CXCL10, CXCL12, ICAM-1, VCAM1 and VEGF was higher in CIDP and GBS compared with controls (p<0.002). The median concentration of IL-8 and IL-1ra was higher in GBS than CIDP or DP or controls, whereas stem cell factor (SCF) and hepatocyte growth factor (HGF) were higher in CIDP than GBS or DP or controls (p<0.002).. Mediators of the recruitment and activation of lymphocytes and monocytes are expressed in the CSF of CIDP and GBS. IL-8 and IL-1ra are characteristic of GBS, whereas growth factors (SCF, HGF) of CIDP are possibly related to chronicity or to the survival/repair processes of neurons.
