Berillo D. Comparative Toxicity of Interferon Beta-1a Impurities of Heavy Metal Ions. Medicina (B Aires) 2022; 58:medicina58040463. [PMID: 35454302 PMCID: PMC9027684 DOI: 10.3390/medicina58040463] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2022] [Revised: 03/17/2022] [Accepted: 03/19/2022] [Indexed: 11/16/2022] Open
Abstract
Background and Objectives: Providing a proper quality control of drugs is essential for efficient treatment of various diseases minimizing the possible side effects of pharmaceutical active substances and potential impurities. Recent in vitro and in vivo studies have shown that certain heavy metalloids and metals interfere with protein folding of nascent proteins in cells and their biological function can be altered. It is unknown whether the drug impurities including heavy metals may affect the tertiary protein structure. Materials and Methods: ReciGen and Rebif are pharmaceutical interferon beta-1a (IFNβ-1a) contained in preparations that are used for parenteral administration. Heavy metal impurities of these samples have been studied by gel electrophoresis, Fourier-transform infrared spectroscopy (FTIR) and inductively coupled plasma mass spectrometry analysis (ICP MS). The concentration of heavy metals including mercury, arsenic, nickel, chromium, iron, and aluminum did not exceed permitted levels established by International Council for Harmonisation guideline for elemental impurities. Results: The ICP MS analysis revealed the presence of heavy metals, moreover zeta potential was significantly different for IFNβ-1a, which can be an indirect indication of the difference in composition of ReciGen and Rebif samples, respectively. FTIR analysis revealed very similar amide I and II bonds at 1654 and 1560 cm−1 attributed to the peptide absorption peaks of IFNβ-1a in Rebif and ReciGen. Conclusions: It was hypothesized that the IFNβ-1a complex binds heavy metals affecting the tertiary protein structure and may lead to some side effects of drug administration. Further testing of IFNβ-1a bioequivalence for parenteral application is necessary.

Abstract
Background Emerging evidence of antibody-independent functions, as well as the clinical efficacy of anti-CD20 depleting therapies, helped to reassess the contribution of B cells during multiple sclerosis (MS) pathogenesis. Objective To investigate whether CD19+ B cells may share expression of the serine-protease granzyme-B (GzmB), resembling classical cytotoxic CD8+ T lymphocytes, in the peripheral blood from relapsing-remitting MS (RRMS) patients. Methods In this study, 104 RRMS patients during different treatments and 58 healthy donors were included. CD8, CD19, Runx3, and GzmB expression was assessed by flow cytometry analyses. Results RRMS patients during fingolimod (FTY) and natalizumab (NTZ) treatment showed increased percentage of circulating CD8+GzmB+ T lymphocytes when compared to healthy volunteers. An increase in circulating CD19+GzmB+ B cells was observed in RRMS patients during FTY and NTZ therapies when compared to glatiramer (GA), untreated RRMS patients, and healthy donors but not when compared to interferon-β (IFN). Moreover, regarding Runx3, the transcriptional factor classically associated with cytotoxicity in CD8+ T lymphocytes, the expression of GzmB was significantly higher in CD19+Runx3+-expressing B cells when compared to CD19+Runx3- counterparts in RRMS patients. Conclusions CD19+ B cells may exhibit cytotoxic behavior resembling CD8+ T lymphocytes in MS patients during different treatments. In the future, monitoring “cytotoxic” subsets might become an accessible marker for investigating MS pathophysiology and even for the development of new therapeutic interventions.

Abstract
BACKGROUND We aimed to evaluate the therapeutic effects of interferon-beta (IFN-β) on hsa-miR29b-3p and hsa-miR326 in isolated T-helper (Th)1 and Th17 cells expressed by relapsing-remitting multiple sclerosis (RRMS) patients before and after 1 year of treatment with IFN-β. METHODS The study was done on 19 RRMS patients pre- and posttreatment with IFN-β to evaluate the frequency of Th1 and Th17 cells by flow cytometry. The expression level of hsa-miR-29b-3p and hsa-miR-326 in isolated Th1 and Th17 cells was assessed by quantitative polymerase chain reaction. Enzyme-linked immunosorbent assay was also used to measure the plasma levels of I interferon -gamma and interleukin (IL)-17A. RESULTS Th17 cells and plasma levels of IL-17A decreased in RRMS patients after IFN-β therapy but hsa-miR-29b-3p and hsa-miR-326 expression had no significant change in treated RRMS patients versus baseline. MxA gene expression was significantly induced upon IFN-β therapy in patients with RRMS. CONCLUSION IFN-β therapy is more effective on Th17 than Th1, but it does not reform altered expression of hsa-miR-326 and hsa-miR-29b-3p in Th17 and Th1, respectively.

Abstract
Beta interferons (IFN-β) are pleiotropic cytokines with antiviral properties. They play important roles in the pathogenesis of multiple sclerosis (MS), an incurable immune-mediated disorder of the central nervous system. The clinical expression of MS is heterogeneous, with relapses of neuroinflammation and with disability accrual in considerable part unrelated to the attacks. The injectable recombinant IFN-β preparations are the first approved disease-modifying treatments for MS. They have moderate efficacy in reducing the frequency of relapses, but good long-term cost-efficacy and safety profiles, so are still widely used. They have some tolerability and adherence issues, partly mitigated in recent years by the introduction of a PEGylated formulation and use of 'smart' autoinjector devices. Their general impact on long-term disability is modest but could be further improved by developing accurate tools for identifying the patient profile of best responders to IFN-β. Here, we present the IFN-β-based immunomodulatory therapeutic approaches in MS, highlighting their place in the current coronavirus disease (COVID-19) pandemic. The potential role of IFN-β in the treatment of COVID-19 is also briefly discussed.

Soluble Receptor Isoform of IFN-Beta (sIFNAR2) in Multiple Sclerosis Patients and Their Association With the Clinical Response to IFN-Beta Treatment. Front Immunol 2021; 12:778204.

Abstract
Purpose Interferon beta receptor 2 subunit (IFNAR2) can be produced as a transmembrane protein, but also as a soluble form (sIFNAR2) generated by alternative splicing or proteolytic cleavage, which has both agonist and antagonist activities for IFN-β. However, its role regarding the clinical response to IFN-β for relapsing-remitting multiple sclerosis (RRMS) is unknown. We aim to evaluate the in vitro short-term effects and after 6 and 12 months of IFN-β therapy on sIFNAR2 production and their association with the clinical response in MS patients. Methods Ninety-four RRMS patients were included and evaluated at baseline, 6 and 12 months from treatment onset. A subset of 41 patients were classified as responders and non-responders to IFN-β therapy. sIFNAR2 serum levels were measured by ELISA. mRNA expression for IFNAR1, IFNAR2 splice variants, MxA and proteases were assessed by RT-PCR. The short-term effect was evaluated in PBMC from RRMS patients after IFN-β stimulation in vitro. Results Protein and mRNA levels of sIFNAR2 increased after IFN-β treatment. According to the clinical response, only non-responders increased sIFNAR2 significantly at both protein and mRNA levels. sIFNAR2 gene expression correlated with the transmembrane isoform expression and was 2.3-fold higher. While MxA gene expression increased significantly after treatment, IFNAR1 and IFNAR2 only slightly increased. After short-term IFN-β in vitro induction of PBMC, 6/7 patients increased the sIFNAR2 expression. Conclusions IFN-β administration induces the production of sIFNAR2 in RRMS and higher levels might be associated to the reduction of therapeutic response. Thus, levels of sIFNAR2 could be monitored to optimize an effective response to IFN-β therapy.

Abstract
Background We aim to overcome limitations of previous clinical and population-based studies by merging a clinical registry to routinely-collected healthcare data, and to specifically describe differences in clinical outcomes, healthcare resource utilization and costs between interferon beta formulations for multiple sclerosis (MS). Methods We included 850 patients with MS treated with interferon beta formulations, from 2015 to 2019, seen at the MS Clinical Care and Research Centre (Federico II University of Naples, Italy) and with linkage to routinely-collected healthcare data (prescription data, hospital admissions, outpatient services). We extracted and computed clinical outcomes (relapses, 6-month EDSS progression using a roving EDSS as reference), persistence (time spent on a specific interferon beta formulation), adherence (medication possession ratio (MPR)), healthcare resource utilization and costs (annualized hospitalization rate (AHR), costs for hospital admissions and DMTs). To evaluate differences between interferon beta formulations, we used linear regression (adherence), Poisson regression (AHR), mixed-effect regression (costs), and Cox-regression models (time varying variables); covariates were age, sex, treatment duration, baseline EDSS and adherence. Results Looking at clinical outcomes, rates of relapses and EDSS progression were lower than studies run on previous cohorts; there was no differences in relapse risk between interferon beta formulations. Risk of discontinuation was higher for Betaferon®/Extavia® (HR = 3.28; 95%CI = 2.11, 5.12; p<0.01). Adherence was lower for Betaferon®/Extavia® (Coeff = -0.05; 95%CI = -0.10, -0.01; p = 0.02), and Avonex® (Coeff = -0.06; 95%CI = -0.11, -0.02; p<0.01), when compared with Rebif® and Plegridy® (Coeff = 0.08; 95%CI = 0.01, 0.16; p = 0.02). AHR and costs for MS hospital admissions were higher for Betaferon®/Extavia® (IRR = 2.38; 95%CI = 1.01, 5.55; p = 0.04; Coeff = 14.95; 95%CI = 1.39, 28.51; p = 0.03). Conclusions We have showed the feasibility of merging routinely-collected healthcare data to a clinical registry for future MS research, and have confirmed interferon beta formulations play an important role in the management of MS, with positive clinical outcomes. Differences between interferon beta formulations are mostly driven by adherence and healthcare resource utilization.

Dealing With Treatment-Confounder Feedback and Sparse Follow-up in Longitudinal Studies: Application of a Marginal Structural Model in a Multiple Sclerosis Cohort. Am J Epidemiol 2021; 190:908-917.

Abstract
The beta-interferons are widely prescribed platform therapies for patients with multiple sclerosis (MS). We accessed a cohort of patients with relapsing-onset MS from British Columbia, Canada (1995-2013), to examine the potential survival advantage associated with beta-interferon exposure using a marginal structural model. Accounting for potential treatment-confounder feedback between comorbidity, MS disease progression, and beta-interferon exposure, we found an association between beta-interferon exposure of at least 6 contiguous months and improved survival (hazard ratio (HR) = 0.63, 95% confidence interval 0.47, 0.86). We also assessed potential effect modifications by sex, baseline age, or baseline disease duration, and found these factors to be important effect modifiers. Sparse follow-up due to variability in patient contact with the health system is one of the biggest challenges in longitudinal analyses. We considered several single-level and multilevel multiple imputation approaches to deal with sparse follow-up and disease progression information; both types of approach produced similar estimates. Compared to ad hoc imputation approaches, such as linear interpolation (HR = 0.63), and last observation carried forward (HR = 0.65), all multiple imputation approaches produced a smaller hazard ratio (HR = 0.53), although the direction of effect and conclusions drawn concerning the survival advantage remained the same.

Abstract
BACKGROUND Disease-modifying therapies (DMTs) for multiple sclerosis (MS) target immunity and have the potential to increase the risk of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection and alter its clinical course. We assessed these risks in patients with MS (PwMS). OBJECTIVE The objective of this study was to describe the overall risk of coronavirus disease 2019 (COVID-19) infection, severe disease course, and potential population-level predictors of COVID-19 infection in PwMS, and to provide a context using a cohort of patients with systemic lupus erythematosus (SLE). In addition, the association of different MS DMTs with the incidence and clinical course of COVID-19 was evaluated. Safety data from the Biogen Global Safety Database are also presented on reported cases of COVID-19 in patients treated with Biogen MS therapies. METHODS The IBM® Explorys electronic health record database of > 72,000,000 patients from US healthcare networks identified patients with MS or SLE, with and without polymerase chain reaction-confirmed COVID-19. COVID-19 cumulative incidence, hospitalization, and deaths among DMT classes were compared using logistic regression (adjusted for age, sex, body mass index, comorbidities, and race/ethnicity). As a secondary data source to assess safety data, COVID-19 reports for Biogen MS therapies were extracted and described from Biogen's Global Safety Database. RESULTS 30,478 PwMS with an open DMT prescription were identified within Explorys; 344 were COVID-19 positive. The most significant risk factors for acquiring COVID-19 were comorbidity score ≥ 1, body mass index ≥ 30, and Black/African ancestry. Similar risk factors were also identified for patients with SLE. Patients with MS were less likely to develop COVID-19 when treated with interferons (0.61%) and glatiramer acetate (0.51%), vs all other MS DMTs (both p < 0.001); anti-CD20 therapy was associated with the highest risk (3.45%; p < 0.0001). In the Biogen Global Safety Database, we identified 1217 patients who were COVID-19 positive treated with intramuscular interferon beta-1a, peginterferon beta-1a, natalizumab, dimethyl fumarate, diroximel fumarate, or fampridine. CONCLUSIONS Comorbidities, obesity, and Black/African ancestry, but not age, were associated with a higher risk of SARS-CoV-2 infection in PwMS. Interferons and glatiramer acetate were associated with a reduced COVID-19 risk, whereas anti-CD20 therapies were associated with an increased risk, within the treated MS cohort. COVID-19 safety reports for patients receiving Biogen MS therapies were consistent with the Explorys database and MS literature, illustrating the replicability and power of this approach.

Abstract
Infection by the SARS-CoV-2 virus, known as COVID-19 (COronaVIrus Disease-19) was initially detected in China in December 2019, and has subsequently spread rapidly throughout the world, to the point that on March 11 the World Health Organization (WHO) reported that the outbreak could be defined as a pandemic. COVID-19 disease ranges from mild flu-like episodes to other serious and even life-threatening conditions, mainly due to acute respiratory failure. These patients are frequently admitted to our Intensive Care Units in relation to acute respiratory distress syndrome. The lack of a treatment based on scientific evidence has led to the use of different management guidelines, in many cases with rapid changes in the applied protocols. Recent reviews in reputed journals have underscored the lack of proven therapies and the need for clinical trials to establish clear and objective treatment guidelines. The present study provides an update on the currently applied treatment, and intends to offer help in relation to daily care, without seeking to replace the protocols adopted in each individual center.

Abstract
Interferon Beta-1a (IFN-β1-a), an immunomodulatory mediator with antiviral effects, has shown in vivo and in vitro activities especially on coronavirus including SARS-CoV-2. COVID-19 defined as the disease caused by infection with SARS-CoV-2. The virus has been illustrated inhibits the production of IFN-β1-a from inflammatory cells. We conducted a retrospective study of all adult confirmed COVID-19 hospitalized patients who received combination of three doses of 12 million international units of IFN-β1-a and Lopinavir 400 mg and Ritonavir 100 mg every 12 h (case group) for 14 days besides standard care and age- and sex- matched COVID-19 patients with receiving lopinavir/ritonavir (control group) at Masih Daneshvari Hospital as a designated hospital for COVID-19 between Feb 19 and Apr 30, 2020. Multivariate analysis was done to determine the impact of IFN-β1-a on outcome and all-cause mortality. 152 cases in IFN-β1-a group and 304 cases as control group were included. IFN-β1-a group stayed at hospital longer and required noninvasive ventilation more than control group (13 vs. 6 days, p = 0.001) and (34% vs. 24%, p = 0.04), respectively. During treatment, 57 (12.5%) patients died. The death rate in case and control groups was 11% and 13% respectively. In multivariate analysis, not receiving IFN-β1-a (HR 5.12, 95% CI: 2.77-9.45), comorbidity (HR 2.28, 95% CI: 1.13-4.60) and noninvasive ventilation (HR 2.77, 95% CI: 1.56-4.93) remained significantly associated with all-cause mortality. In this study, risk of death decreased by using IFN-β1-a in COVID-19 patients. More clinical study will be necessary to measure efficacy of IFN-β1-a in COVID-19 treatment.

Abstract
BACKGROUND Subcutaneous (sc) interferon (IFN) β-1a reduces relapse rates and delays disability progression in patients with MS. We examined the association of the year 1 Magnetic Resonance Imaging in MS (MAGNIMS) score with long-term clinical disease activity (CDA) -free status and confirmed disability progression in patients treated with sc IFN β-1a in PRISMS. METHODS Patients treated with sc IFN β-1a three-times-weekly (22 or 44 μg; pooled data) were classified by MAGNIMS score (0, n = 129; 1, n = 108; 2, n = 130) at year 1. Hazard ratios (HR; 95% confidence intervals [CI]) for risk of CDA and confirmed Expanded Disability Status Score (EDSS) progression were calculated by MAGNIMS score for up to 15 years of follow-up. RESULTS The risk of CDA was higher with a year 1 MAGNIMS score of 1 versus 0 (HR 1.82 [1.38-2.41]), 2 versus 0 (2.63 [2.01-3.45]) and 2 versus 1 (1.45 [1.11-1.89], all p < 0.0001). The same outcome was observed with the risk of confirmed EDSS progression (1 versus 0: 1.93 [1.23-3.02]; 2 versus 0: 2.95 [1.95-4.46]; 2 versus 1: 1.53 [1.05-2.23]; all p < 0.0001). CONCLUSION In PRISMS, MAGNIMS score at Year 1 predicted risk of CDA and confirmed disability progression in sc IFN β-1a-treated patients over up to 15 years. PRISMS-15 clinicaltrial.gov identifier: NCT01034644.

Type I interferons (IFN-I) were first discovered as an antiviral factor by Isaacs and Lindenmann in 1957, but they are now known to also modulate innate and adaptive immunity and suppress proliferation of cancer cells. While much has been revealed about IFN-I, it remains a mystery as to why there are 16 different IFN-I gene products, including IFNβ, IFNω, and 12 subtypes of IFNα. Here, we discuss shared and unique aspects of these IFN-I in the context of their evolution, expression patterns, and signaling through their shared heterodimeric receptor. We propose that rather than investigating responses to individual IFN-I, these contexts can serve as an alternative approach toward investigating roles for IFNα subtypes. Finally, we review uses of IFNα and IFNβ as therapeutic agents to suppress chronic viral infections or to treat multiple sclerosis.

Abstract
BACKGROUND In recent investigations addressing neurodegenerative diseases, especially multiple sclerosis (MS), the roles of brain-derived neurotrophic factor (BDNF) and interleukin-6 (IL-6) have been examined. METHODS Forty-five relapsing-remitting MS (RRMS) patients, including 32 IFN-β-treated and 13 newly identified untreated cases as well as 45 sex- and age-matched healthy controls, were recruited in the study. Plasma levels of BDNF and IL-6 were assessed using the ELISA method. Data were analyzed by SPSS (ver.21). RESULTS There were significant differences between the case and healthy control groups in terms of the plasma levels of BDNF (p value = 0.044) and IL-6 (p value <0.001). Besides, the treatment with IFN-β had no significant impact on the level of BDNF or IL-6 in RRMS patients as compared to healthy controls (p value = 0.716 and 0.623 for BDNF and IL-6, respectively). Furthermore, the increase in the plasma levels of BDNF and IL-6 indicated a direct correlation in the case group (r = 0.508, p value = 0.008). In detail, following the classification of the case group into 2 subgroups of IFN-β-treated and untreated patients, a direct positive correlation was observed between the plasma levels of BDNF and IL-6 in IFN-β-treated patients (r = 0.495, p value = 0.026). CONCLUSION The IFN-β treatment seems not to be effective for upregulating BDNF and IL-6 in RRMS patients.

Abstract
We present the case of a 39-year-old man with epigastric pain, nausea and vomiting. The patient scored 4 in the Visual Triage Checklist of acute respiratory symptoms; a COVID-19 swab was taken. Prompt review of the peripheral blood smear showed evidence of microangiopathic haemolytic anaemia and thrombocytopenia. Because the patient had a picture of thrombotic thrombocytopenic purpura, plasma exchange and corticosteroids were started immediately. After 3 days, he developed severe ischaemic stroke and his swabs came back positive for COVID-19 by reverse transcription PCR. Therefore, triple therapy was started (lopinavir/ritonavir, ribavirin and interferon beta-1b). White blood cell count reached 50×109/L (normal range, 4.5-11×109/L), mainly neutrophils. All the workup for autoimmune diseases was negative. The patient showed delayed improvement in lactate dehydrogenase, haemoglobin and platelet count until we increased the volume of plasma exchange and subsided the inflammatory response of COVID-19. After that, the patient showed an excellent recovery.

Abstract
Current smoking is associated with increased risk of severe COVID-19, but it is not clear how cigarette smoke (CS) exposure affects SARS-CoV-2 airway cell infection. We directly exposed air-liquid interface (ALI) cultures derived from primary human nonsmoker airway basal stem cells (ABSCs) to short term CS and then infected them with SARS-CoV-2. We found an increase in the number of infected airway cells after CS exposure with a lack of ABSC proliferation. Single-cell profiling of the cultures showed that the normal interferon response was reduced after CS exposure with infection. Treatment of CS-exposed ALI cultures with interferon β-1 abrogated the viral infection, suggesting one potential mechanism for more severe viral infection. Our data show that acute CS exposure allows for more severe airway epithelial disease from SARS-CoV-2 by reducing the innate immune response and ABSC proliferation and has implications for disease spread and severity in people exposed to CS.

Abstract
Multiple sclerosis (MS) is an autoimmune-type inflammatory disorder in human central nervous system. Recombinant interferon beta (IFN-β) decreases the number of relapses and postpones disability progression in MS. However, up to 50% of patients treated with interferon beta continue experiencing relapses and/or worsening disability. Single nucleotide polymorphisms in different genes have been known to show significant associations with response to IFN-β in MS patients. In the present work, we examined the potential role of TRAILR1 and GRIA3 genes polymorphisms on response to IFN-β therapy in Iranian MS patients. The DNA was extracted from blood samples by standard procedures from 73 patients diagnosed with Multiple Sclerosis that were either responded to IFN-β or did not. We carried out RFLP -PCR and tetra-primer ARMS-PCR methods to study of rs20576 and rs12557782, respectively. All results were analyzed using the SPSS software. TRAILR1 rs20576 genotype frequencies in responders and non-responders were similar (χ2 = 0.26, P = 0.87, Fisher, s Exact test). Our results showed that response to IFN-β has not association with sex (p = 0.73). Also, genotypic frequencies of GRIA3 rs12557782 had no significant differences between two groups of female population (χ2 = 3.75, p = 0.15). Furthermore, it had not been any statistical differences between responder and non-responder males (χ2 = 0.7, p = 0.4) related to the SNP. Our results analysis revealed no significant association between the studied SNPs (TRAILR1 rs20576 and GRIA3rs 12,557,782) and response to IFN-β in Iranian MS patients.

Abstract
BACKGROUND Multiple sclerosis (MS) is an immune-mediated disease that damages myelin in the central nervous system (CNS). We investigated the profile of CCN3, a known regulator of immune function and a potential mediator of myelin regeneration, in multiple sclerosis in the context of disease state and disease-modifying treatment. METHODS CCN3 expression was analysed in plasma, immune cells, CSF and brain tissue of MS patient groups and control subjects by ELISA, western blot, qPCR, histology and in situ hybridization. RESULTS Plasma CCN3 levels were comparable between collective MS cohorts and controls but were significantly higher in progressive versus relapsing-remitting MS and between patients on interferon-β versus natalizumab. Higher body mass index was associated with higher CCN3 levels in controls as reported previously, but this correlation was absent in MS patients. A significant positive correlation was found between CCN3 levels in matched plasma and CSF of MS patients which was absent in a comparator group of idiopathic intracranial hypertension patients. PBMCs and CD4+ T cells significantly upregulated CCN3 mRNA in MS patients versus controls. In the CNS, CCN3 was detected in neurons, astrocytes and blood vessels. Although overall levels of area immunoreactivity were comparable between non-affected, demyelinated and remyelinated tissue, the profile of expression varied dramatically. CONCLUSIONS This investigation provides the first comprehensive profile of CCN3 expression in MS and provides rationale to determine if CCN3 contributes to neuroimmunological functions in the CNS.

Abstract
Several predictors of non-response to interferon-β (IFN-β) treatment have been proposed. The aim of the study was to identify metabolite changes in the normal-appearing cortex of the posterior cingulate gyrus (PCG) using MRS (magnetic resonance spectroscopy) and to investigate their usefulness in prognosis of NEDA (no evidence of disease activity) in the 3-year follow-up and in monitoring treatment effects during IFN-β therapy in the parallel period of time in multiple sclerosis (MS) patients. Forty-one relapsing-remitting MS patients and 41 sex- and age-matched healthy subjects underwent routine MRI protocol with MRS sequence with the use of a 1.5 T magnet. A single voxel size of 2x2x2cm was inserted in the cortex of PCG region. Associations between baseline metabolic ratios, conventional MRI findings, demographic and clinical factors, and NEDA status were evaluated using logistic, Cox, and multinomial logistic regression models. MS patients in the initial scan showed a statistically significant decline in NAA/Cr ratio (p < 0.0001) and an increase in Cho/Cr ratio (p = 0.016) compared to the control group. None of the MRS parameters predicted NEDA maintenance or the time to loss of NEDA. In treatment monitoring only an improvement in the combination of NAA/Cr + Cho/Cr ratio between the 1st and 2nd year of treatment was connected with a 6.27-fold chance (p = 0.025) of having simultaneous NEDA maintenance. To conclude, metabolite alterations in the PCG region did not predict NEDA maintenance, but they seem to be useful in treatment monitoring.

Abstract
BACKGROUND Relapsing-remitting multiple sclerosis (RRMM) is a chronic, progressive, inflammatory and immune-mediated disease that affects the central nervous system and is characterized by episodes of neurological dysfunction followed by a period of remission. The pharmacological strategy aims to delay the progression of the disease and prevent relapse. Interferon beta and glatiramer are commonly used in the Brazilian public health system and are available to patients who meet the guideline criteria. The scenario of multiple treatments available and in development brings the need for discussion and evaluation of the technologies already available before the incorporation of new drugs. This study analyses the effectiveness of first-line treatment of RRMS measured by real-world evidence data, from the Brazilian National Health System (SUS). METHODS AND FINDINGS We conducted a non-concurrent national cohort between 2000 and 2015. The study population consisted of 22,722 patients with RRMS using one of the following first-line drugs of interest: glatiramer or one of three presentations of interferon beta. Kaplan-Meier analysis was used to estimate the time to treatment failure. A univariate and multivariate Cox proportional hazard model was used to evaluate factors associated with treatment failure. In addition, patients were propensity score-matched (1:1) in six groups of comparative first-line treatments to evaluate the effectiveness among them. The analysis indicated a higher risk of treatment failure in female patients (HR = 1.08; P = 0,01), those with comorbidities at baseline (HR = 1.20; P<0,0001), in patients who developed comorbidities after starting treatment (i.e., rheumatoid arthritis-HR = 1.65; P<0,0001), those exclusive SUS patients (HR = 1.31; P<0,0001) and among patients using intramuscular interferon beta (IM βINF-1a) (28% to 60% compared to the other three treatments; P<0,0001). Lower risk of treatment failure was found among patients treated with glatiramer. CONCLUSIONS This retrospective cohort suggests that glatiramer is associated with greater effectiveness compared to the three presentations of interferon beta. When evaluating beta interferons, the results suggest that the intramuscular presentation is not effective in the treatment of multiple sclerosis.

Abstract
Multiple Sclerosis (MS) is a chronic inflammatory disease of the central nervous system (CNS) with unpredictable clinical outcome. As such, there is an urgent need to identify biomarkers that can predict the treatment response. Therefore, in an open-label, clinical, paraclinical and molecular prospective study, we assessed 50 interferon (IFN) treated MS patients for Rio Score (RS)/Modified Rio Score (MRS) and densitometric expression of the interferon-induced protein 35 (IFI35), a signal-protein with potential to be clinically relevant in the management of the disease. We found 4.92-fold upregulated IFI35 in IFN-treated MS group respect to healthy controls (p < .0001) and 2.31-fold respect to untreated MS group (p < .0001). Moreover, IFI35 expression profile correlated with RS and MRS rank values (r = -0.6018, p < .0001; r = -0.620, p < .0001), white matter volume (r = -0.5041; p = .0017) and cerebral lesion load (r = -0.5075; p = .0026). Finally, the main proportion of IFN-treated MS patients non-reaching the 65% threshold in IFI35 expression leaved the RS/MRS rank value 0 in a period ranging from 5 to 15 months (p < .0001) from the study entry; instead, all patients that reaching this threshold maintained the RS/MRS value 0 until the study end (p < .0001). In conclusion, the expression level of IFI35 in untreated MS patients highlights a correlation with neuroinflammation. Furthermore, IFI35 expression in IFN-treated MS patients shows a modular correlation between dosing regimes, which is predictive for long-term clinical outcome and drug efficacy.

Abstract
BACKGROUND SARS-CoV-2 viral infection causes COVID-19 that can result in severe acute respiratory distress syndrome (ARDS), which can cause significant mortality, leading to concern that immunosuppressive treatments for multiple sclerosis and other disorders have significant risks for both infection and ARDS. OBJECTIVE To examine the biology that potentially underpins immunity to the SARS-Cov-2 virus and the immunity-induced pathology related to COVID-19 and determine how this impinges on the use of current disease modifying treatments in multiple sclerosis. OBSERVATIONS Although information about the mechanisms of immunity are scant, it appears that monocyte/macrophages and then CD8 T cells are important in eliminating the SARS-CoV-2 virus. This may be facilitated via anti-viral antibody responses that may prevent re-infection. However, viral escape and infection of leucocytes to promote lymphopenia, apparent CD8 T cell exhaustion coupled with a cytokine storm and vascular pathology appears to contribute to the damage in ARDS. IMPLICATIONS In contrast to ablative haematopoietic stem cell therapy, most multiple-sclerosis-related disease modifying therapies do not particularly target the innate immune system and few have any major long-term impact on CD8 T cells to limit protection against COVID-19. In addition, few block the formation of immature B cells within lymphoid tissue that will provide antibody-mediated protection from (re)infection. However, adjustments to dosing schedules may help de-risk the chance of infection further and reduce the concerns of people with MS being treated during the COVID-19 pandemic.

Abstract
In this review, we discuss the latest developments in research pertaining to virus-induced asthma exacerbations and consider recent advances in treatment options. Asthma is a chronic disease of the airways that continues to impose a substantial clinical burden worldwide. Asthma exacerbations, characterised by an acute deterioration in respiratory symptoms and airflow obstruction, are associated with significant morbidity and mortality. These episodes are most commonly triggered by respiratory virus infections. The mechanisms underlying the pathogenesis of virus-induced exacerbations have been the focus of extensive biomedical research. Developing a robust understanding of the interplay between respiratory viruses and the host immune response will be critical for developing more efficacious, targeted therapies for exacerbations. CONCLUSION: There has been significant recent progress in our understanding of the mechanisms underlying virus-induced airway inflammation in asthma and these advances will underpin the development of future clinical therapies.
