Prognostic biomarkers are highly needed. Objective To assess the prognostic value of intrathecal IgM synthesis, cerebrospinal fluid and serum IL-2, IL-6, IL-10, chitinase 3-like 2 and neurofilament heavy chains obtained early after the onset of the disease. Methods 58 patients after the first manifestation of multiple sclerosis were included. After the initial diagnostic assessment including serum and cerebrospinal fluid biomarkers, all patients initiated therapy with either glatiramer acetate, teriflunomide, or interferon beta. To assess the evolution of the disease, we followed the patients clinically and with MRI for two years. Results The IL-2:IL-6 ratio (both in cerebrospinal fluid) <0.48 (p = 0.0028), IL-2 in cerebrospinal fluid ≥1.23pg/ml (p = 0.026), and chi...

Its immunopathogenesis has been proposed to include early cerebrospinal fluid (CSF) lymphocytosis, subsequent CNS disease restriction and B cell mechanism predominance. There are limited data regarding T cell involvement in the disease. To contribute to the current knowledge, we investigated the complex system of chemokines and cytokines related to B and T cell functions in CSF and sera samples from anti-NMDAR encephalitis patients at different time-points of the disease. One patient in our study group had a long-persisting coma and underwent extraordinary immunosuppressive therapy. Methods Twenty-seven paired CSF/serum samples were collected from nine patients during the follow-up period (median 12 months, range 1–26 months). The patient samples were stratified into three periods after the onset of the first disease symptom and compared with the controls...

V posledni době byly popsany připady, kdy s nalezem těchto protilatek byly sdruženy projevy demyelinizacniho onemocněni, a to i u pa cientů bez klinických projevů NMDAR encefalitidy. Cilem prace je popsat charakteristiky demyelinizacniho onemocněni u pa cientů s pozitivitou anti-NMDAR v nasem souboru. Metodika a soubor: Vysetřeni anti-NMDAR bylo indikovano při klinickem podezřeni na autoimunitni encefalitidu a bylo provedeno v seru a v likvoru nepřimou imunofl urescenci metodou cel l-based as say na fi xovaných buňkach transfekovaných pro daný antigen. Klinický průběh a MR nalez odpovidajici demyelinizacnimu onemocněni byl hodnocen dle přislusných dia gnostických kriterii. Výsledky: V obdobi 2012– 2015 jsme identifi kovali 11 pa cientů s autoimunitni encefalitidou a pozitivitou anti- -NMDAR. Deset z nich splňovalo kriteria NMDAR encefalitidy, u...

Průběh choroby je interindividualně znacně variabilni. I přes významný pokrok v diagnostice roztrousene sklerozy v poslednich desetiletich stale neexistuje spolehlivý test, který by identifikoval pacienty s relativně přiznivým průběhem a pacienty s těžkou agresivni formou nemoci. Prognozu onemocněni je do urcite miry možne predikovat dle klinických projevů ci charakteru postiženi na magneticke rezonanci. V soucasne době se hledaji nove parametry lepe vyjadřujici průběh onemocněni již na jeho zacatku. Přesnějsi stratifikace nemoci ma umožnit volbu terapie přiměřenou formě nemoci. V clanku předkladame aktualni přehled potencialnich biomarkerů průběhu roztrousene sklerozy z periferni krve a likvoru a v bližsim detailu představujeme ty, ktere jsou v soucasne době středem zajmu – neurofilamenta, chitinase 3-like proteiny, vitamin D, mikroRNA.

In this study, we used a proteomic approach in search of novel clinically relevant biomarkers in these types of encephalitides.MethodsSwedish and Czech tertiary neuroimmunology centers collaborated in this retrospective exploratory study. Fifty‐eight cerebrospinal fluid (CSF) samples of 28 patients with AE (14 definite NMDAR, 14 with definite LGI1 encephalitis) and 30 controls were included. CSF samples were analyzed using proximity extension assay technology (Olink Target 96 Inflammation panel). For each CSF sample, 92 proteins were measured. Clinical variables were retrospectively collected, and correlations with protein levels were statistically analyzed.ResultsPatients and controls differed significantly in the following 18 biomarkers: TNFRSF9, TNFRSF12, TNFRSF14, TNFβ, TNFα, ...

The Wilcoxon signed ranked test was used for pairwise analyses of the CSF and sera samples to detect differences between the CNS compartment and the peripheral blood. The interesting differences in the general chemokine and cytokine levels between the CNS compartment and the peripheral blood are depicted. A) The CXCL10 concentration was markedly higher in CSF than in serum, whereas B) the CXCL13 and D) BAFF concentrations showed the opposite trend. Because patient No. 1 provided more than 1 sample per period, the average value for this patient was used for multiple-group analysis; a special sign marks this value. (TIF 79 kb)

The increased resistance against the cytostatic agent PMEDAP during longterm treatment was found to be associated with overexpression of MRP4 and MRP5 genes. The course of both gene activation differs significantly. While the MRP5 function is important in the onset of PMEDAP resistance, the intensity of the relative MRP4 gene expression increases rather continuously. Our data indicate cooperative acting of both MRP4 and MRP5 genes during the PMEDAP resistance development.
