Abstract

Background and purpose: Clinical outcomes of multiple sclerosis (MS) patients affected by coronavirus disease 2019 (COVID-19) have been thoroughly investigated, but a further analysis on main signs and symptoms and their risk factors still needs attention. The objective of this study was to group together and describe based on similarity the most common signs and symptoms of COVID-19 in MS patients and identify all factors associated with their manifestation. Method: Logistic and linear regression models were run to recognize factors associated with each pooled group of symptoms and their total number. Results: From March 2020 to November 2021, data were collected from 1354 MS patients with confirmed infection of COVID-19. Ageusia and anosmia was less frequent in older people (odds ratio [OR] 0.98; p=0.005) and more in smoker patients (OR 1.39; p=0.049). Smoke was also associated with an incremental number of symptoms (OR 1.24; p=0.031), substance abuse (drugs or alcohol), conjunctivitis and rash (OR 5.20; p=0.042) and the presence of at least one comorbidity with shortness of breath, tachycardia or chest pain (OR 1.24; p=0.008). Some disease-modifying therapies were associated with greater frequencies of certain COVID-19 symptoms (association between anti-CD20 therapies and increment in the number of concomitant symptoms: OR 1.29; p=0.05). Differences in frequencies between the three waves were found for flu-like symptoms (G1, p=0.024), joint or muscle pain (G2, p=0.013) and ageusia and anosmia (G5, p < 0.001). All cases should be referred to variants up to Delta. Conclusion: Several factors along with the choice of specific therapeutic approaches might have a different impact on the occurrence of some COVID-19 symptoms.

Abstract

In the last years, change in multiple sclerosis (MS) therapeutic scenario has highlighted the need for an improved doctor-patient communication in advance of treatment initiation in order to allow patient's empowerment in the decision-making process. Aims: The aims of our project were to review the strategies used by Italian MS specialists to inform patients about treatment options and to design a multicentre shared document that homogenizes the information about disease-modifying treatment (DMTs) and the procedure of taking informed consent in clinical practice. Results: The new resource, obtained by consensus among 31 neurologists from 27 MS Centres in Italy with the supervision of a medico-legal advisor, received the aegis of Italian Neurological Society (SIN) and constitutes a step toward a standardized decision process around DMTs in MS.

Abstract

• Neurofilament light chains (NfL) require ultrasensitive techniques to be measured in the serum, and different platforms are available: Ella™, Lumipulse™, and SIMOA™. • In newly diagnosed relapsing-remitting multiple sclerosis (MS) patients cerebrospinal fluid (CSF) and serum NfL absolute levels strongly correlated between assays, although being more elevated with Ella™. • SIMOA™ and Lumipulse™ showed high agreement for serum and CSF values. Neurofilament light chains (NfL) are cytoskeletal biomarkers of axonal damage, about 40-fold higher in cerebrospinal fluid (CSF) compared to serum, and requiring ultrasensitive techniques to be measured in this latter fluid. To compare CSF and serum NfL levels in multiple sclerosis (MS) patients using different platforms. 60 newly diagnosed relapsing-remitting MS patients (38 females; median age: 36.5 years, range: 15–60) were enrolled before steroid or disease-modifying treatments. CSF and serum NfL were measured with: the commercial Ella™ microfluidic platform (Bio-Techne), the Lumipulse™ Chemiluminescent Enzyme ImmunoAssay (Fujirebio), and the SIMOA™ on the SR-X instrument using NF-light assays (Quanterix). CSF and serum NfL absolute levels strongly correlated between assays, although being more elevated with Ella™. Passing-Bablok regression showed high agreement in measuring CSF NfL between assays (with greater proportional difference using Ella™), and very high agreement for serum comparing SIMOA™ and Lumipulse™. Similarly, the Bland-Altman comparison evidenced lower biases for Lumipulse™ for both fluids. CSF and serum NfL in naïve MS patients are reliably measured with all assays. Although not interchangeable, SIMOA™ and Lumipulse™ showed high agreement for serum and CSF values. [ABSTRACT FROM AUTHOR]

Abstract

The article presents a study of the potential of early binding antibody (BAb) titers or different interferon-beta (IFN-b) biomarkers to predict neutralizing antibodies (NAb). The study included patients with multiple sclerosis (MS) or clinically isolated syndrome (CIS) that receive de novo IFN-b treatment. Results showed that BAb titers reliably predict Nabs, with CXCL-10 as a potential sensitive biomarker for IFN-b response and abrogation by anti-IFN-b antibodies.

Abstract

Biological activity of interferon-beta (IFNβ) can be assessed by measuring IFN-stimulated genes (ISGs). Among them, myxovirus resistance protein A (MxA) appears to have the highest specificity, but it has no role in the pathogenesis of multiple sclerosis (MS). To investigate the reliability of MxA as a biomarker, we compared its expression to that of two other ISGs: TNF-related apoptosis-inducing ligand (TRAIL) and X-linked inhibitor of apoptosis factor-1 (XAF-1). Both were shown to be involved in immunoregulatory mechanisms and might play a role in MS. Quantitative-PCR measurements were performed in peripheral blood mononuclear cells from 73 MS patients after short-term and long-term treatment with IFNβ. A time-dependent response for multiple ISGs was observed in all patients after short-term treatment. In contrast, long-term treatment induced concurrent inhibition of ISGs in 12.3% (9/73) of patients, in whom neutralizing antibodies (NAbs) were detectable. Besides, 22% (16/73) of chronically treated patients showed a non-NAbs-related abrogation of TRAIL expression. In summary, 1) MxA expression was significantly higher than both TRAIL and XAF-1, and 2) MxA was the most sensitive gene to detect decreased bioavailability due to NAbs. These findings identify MxA as an appropriate biomarker for IFNβ, although there is no evidence for a functional role of it in MS. [ABSTRACT FROM AUTHOR]

Abstract

Background: MxA gene expression is one of the most appropriate markers of biological activity of exogenous interferon (IFN) beta. Methods: We quantified MxA mRNA for five consecutive days in 62 patients treated with IFN beta (16, Avonex; 10, Betaferon; 24, Rebif 22; 12, Rebif 44), by quantitative-competitive polymerase chain reaction. Every three months, IFN beta induced neutralising antibodies (NAbs) were evaluated in sera using a cytopathic effect assay. Results: Two categories of patients were identified: one group (49/62) hada sharp post-injection increase in MxA expression (defined as "IFN beta biological responder"), whereas the other group (13/62) had no MxA induction after IFN beta administrations (defined as "IFN beta biological non-responder"). In 11 / 13 biological non-responders, the persistent presence of NAbs correlated with abolished biological activity, independently of treatment regimen. The two remain in- IFN beta biological non-responders were NAb-. Among the 49 IFN beta biological responders, biological activity was comparable between the four preparations on day 2 and 3 (+12 and +36 hours post-injection), but it was greater in Betaferon and both Rebif preparations on day 1,4, and 5. In biological responders treated three times a week, only 82% (59/72) of injections were considered effective, compared with 100% (13/13) of Avonex injections. Conclusion: Our results suggest that an optimal IFN beta regimen is not yet available: Avonex, given once a week, shows lower cumulative biological activity. On the other hand, both Betaferon and Rebif, given three times a week, show 18% biologically ineffective injections and higher risk of developing NAbs, which abolish biological activity.

Abstract

Multiple sclerosis (MS) is an autoimmune inflammatory disease of the central nervous system caused by a complex interaction between multiple genes and environmental factors. HLA region is the strongest susceptibility locus, but recent huge genome-wide association studies identified new susceptibility genes. Among these, BACH2, PTGER4, RGS1 and ZFP36L1 were highlighted. Here, a gene expression analysis revealed that three of them, namely BACH2, PTGER4 and ZFP36L1, are down-regulated in MS patients' blood cells compared to healthy subjects. Interestingly, all these genes are involved in the immune system regulation with predominant anti-inflammatory role and their reduction could predispose to MS development. [ABSTRACT FROM AUTHOR]

Abstract

Abstract: We recently found a gene signature for multiple sclerosis (MS) that reverted to normal during pregnancy in MS patients and included NR4A2 and TNFAIP3, key molecules in anti-inflammatory processes. Here we focus on the expression levels of these two genes in monocytes and CD4+ T cells from healthy controls and treatment-naïve RRMS patients. Our findings show that monocytes play a key role in the dysregulated anti-inflammatory response, being the expression of both genes down-regulated in these cells in RRMS patients with respect to healthy individuals. CD4+ T cells seem to have only a marginal part, because we can observe only a slight down-regulation in NR4A2. [Copyright &y& Elsevier]

Abstract

Balance impairment is common in Multiple Sclerosis (MS) patients. We administered the modified Clinical Test of Sensory Interaction on Balance (mCTSIB) to 73 MS patients and 57 healthy controls, with the aim to collect normative data and compare sensitivity of mCTSIB and clinical examination in detecting balance impairment. Subjects were asked to stand quietly upright for 10 s with eyes opened and then eyes closed (EC) (3 times per condition) on a firm surface on a fixed dual forceplate. The centre of gravity (COG) sway was expressed as velocity (deg/s) and path length (mm); MS patients were examined with the Romberg Test (RT), scored according to Neurostatus. mCTSIB-EC clearly allowed to differentiate patients with positive RT (0.38 deg/s, CI 0.32–0.43) from those with negative RT (0.19 deg/s, 95% CI 0.17–0.21, p < 0.001). ROC analysis identified a cut-off value of 0.5 deg/s to define “positivity” to the mCTSIB (sensitivity 100%, specificity 95%, PPV 82%, NPV 100%). mCTSIB detected balance impairment in 19 MS patients (10 with negative RT). Compared to RT, the computerized posturographic test is more sensitive in detecting balance impairment in MS patients. It is easy to perform, fast to administer, not operator-dependent and provides objective data on postural control. [ABSTRACT FROM AUTHOR]

Abstract

We investigated the Intertrial Variability and Relative Intertrial Variation (RIV) of latency and area of motor responses to High Voltage Electric Stimulation (HVES) of lumbo-sacral roots and to Transcranial Magnetic Stimulation (TMS) recorded from several sites of lower limbs. The purpose was to obtain normative variability values to detect significant changes in the individual patient in follow up studies. Maximal CMAPs to HVES of lumbo-sacral roots were obtained from 10 proximal and distal muscle districts of lower limbs; MEPs to TMS using the double cone coil were recorded from the same sites. The procedure was repeated twice, 1–2 days apart, in 30 subjects, including healthy volunteers and clinically stable multiple sclerosis patients. The use of stable recording and stimulation sites with maximal root-CMAPs and adequately stabilized MEPs allowed a significant reduction of ITV for all latency and area parameters. Mean RIV values (5th–95th percentile) for Central Motor Conduction Time and Area Ratio (MEP/CMAP) did not exceeded −14.8 and +16.0 ms and −26.0 and +33.7 mV ms, respectively. The combined monitoring of latency and areas indexes allows assessment of both conduction slowing and conduction failure, i.e the variable association of axonal damage and conduction block, which directly correlates with motor impairment.
