RESUMO

BACKGROUND: Neurosarcoidosis occurs symptomatically in 5-10% of patients with sarcoidosis, and hydrocephalus is a rare complication of neurosarcoidosis, with either acute or subacute onset and presenting symptoms related to increased intracranial pressure. It represents a potentially fatal manifestation with a mortality rate of 22% (increased to 75% in case of coexistence of seizures) that requires a prompt initiation of treatment. High-dose intravenous corticosteroid treatment and neurosurgical treatment must be considered in all cases of neurosarcoidosis hydrocephalus. CASE PRESENTATION: Here we present a case of hydrocephalus in neurosarcoidosis, complicated by generalized seizures, in a 29-year-old Caucasian male patient treated with medical treatment only, with optimal response. CONCLUSION: Since neurosurgery treatment can lead to severe complications, this case report underlines the possibility to undergo only medical treatment in selected cases. Further studies are needed to stratify patients and better identify those eligible for only medical approach.

RESUMO

Corticobasal syndrome (CBS) is a clinical syndrome determined by various underlying neurodegenerative disorders requiring a pathological assessment for a definitive diagnosis. A literature review was performed following the methodology described in the Cochrane Handbook for Systematic Reviews to investigate the additional value of traditional and cutting-edge cerebrospinal fluid (CSF) and serum/plasma biomarkers in profiling CBS. Four databases were screened applying predefined inclusion criteria: (1) recruiting patients with CBS; (2) analyzing CSF/plasma biomarkers in CBS. The review highlights the potential role of the association of fluid biomarkers in diagnostic workup of CBS, since they may contribute to a more accurate diagnosis and patient selection for future disease-modifying agent; for example, future trial designs should consider baseline CSF Neurofilament Light Chains (NfL) or progranulin dosage to stratify treatment arms according to neuropathological substrates, and serum NfL dosage might be used to monitor the evolution of CBS. In this scenario, prospective cohort studies, starting with neurological examination and neuropsychological tests, should be considered to assess the correlations of clinical profiles and various biomarkers.

RESUMO

The present study aims to describe the state of the art of fluid biomarkers use in ongoing multiple sclerosis (MS) clinical trials.A review of 608 ongoing protocols in the clinicaltrials.gov and EudraCT databases was performed. The trials enrolled patients with a diagnosis of relapsing remitting MS, secondary progressive MS, and/or primary progressive MS according to Revised McDonald criteria or relapsing MS according to Lublin et al. (2014). The presence of fluid biomarkers among the primary and/or secondary study outcomes was assessed.Overall, 5% of ongoing interventional studies on MS adopted fluid biomarkers. They were mostly used as secondary outcomes in phase 3-4 clinical trials to support the potential disease-modifying properties of the intervention. Most studies evaluated neurofilament light chains (NfLs). A small number considered other novel fluid biomarkers of neuroinflammation and neurodegeneration such as glial fibrillary acid protein (GFAP).Considering the numerous ongoing clinical trials in MS, still a small number adopted fluid biomarkers as outcome measures, thus testifying the distance from clinical practice. In most protocols, fluid biomarkers were used to evaluate the effectiveness of approved second-line therapies, but also, new drugs (particularly Bruton kinase inhibitors). NfLs were also adopted to monitor disease progression after natalizumab suspension in stable patients, cladribine efficacy after anti-CD20 discontinuation, and the efficacy of autologous hematopoietic stem cell transplant (AHSCT) compared to medical treatment. Nevertheless, further validation studies are needed for all considered fluid biomarkers to access clinical practice, and cost-effectiveness in the "real word" remains to be clarified.

RESUMO

BACKGROUND: Clinicians are increasingly recognizing the importance of shared decision-making in complex treatment choices, highlighting the importance of the patient's rationale and motivation for switching therapies. This study aimed to evaluate the association between different modalities of changing multiple sclerosis (MS) treatments, cognitive profile and attitude and preferences of patients concerning treatment choice. METHODS: This multicenter cross-sectional study was conducted at 28 Italian MS centers in the period between June 2016 and June 2017. We screened all MS patients treated with any DMT, with a treatment compliance of at least 80% of therapy administered during the 3 last months who needed to modify MS therapy because of efficacy, safety or other reasons during a follow-up visit. At the time of switching the symbol digit modalities test (SDMT) and the Control Preference Scale (CPS) were evaluated. According to the CPS, patients were classified as "active" (i.e. who prefer making the medical decision themselves), "collaborative" (i.e. who prefer decisions be made jointly with the physician), or "passive" (i.e. who prefer the physician make the decision). RESULTS: Out of 13,657 patients recorded in the log, 409 (3%) changed therapy. Of these, 336 (2.5%) patients, 69.6% were female and with mean age 40.6 ± 10.5 years, were enrolled. According to the CPS score evaluation, a significant high percentage of patients (51.1%) were considered collaborative, 74 patients (22.5%) were passive, and 60 (18.2%) patients were active. Stratifying according to CPS results, we found a higher SDMT score among collaborative patients compared to active and passive ones (45.8 ± 12.3 versus 41.0 ± 13.2 versus 41.7 ± 12.8, p < 0.05). CONCLUSION: In this study, the CPS evaluation showed that more than 50% of patients who needed to change therapy chose a "collaborative" role in making treatment decision. Cognitive profile with SDMT seems to correlate with patients' preference on treatment decision, showing better scores in collaborative patients.

RESUMO

The aim of the present study is to evaluate the composite role of k index in the initial assessment of Multiple Sclerosis (MS) patients and to select useful cut-offs exportable in clinical practice. We analysed CSF/serum samples of 140 patients and followed-up the CIS/MS subgroup for 7 years. Our results suggest κ index as a quantitative diagnostic and prognostic biomarker in MS, significantly associated to baseline lesion load and to successive clinical course. We propose k index ≥106 as a prognostic cut-off to select patients at major risk of relapse, potentially influencing initial therapeutic decisions.

RESUMO

BACKGROUND: clinical factors and frequency of disease-modifying therapy (DMT) changes/interruptions in relapsing-remitting multiple sclerosis (RRMS) patients have not been well defined. The aim of this study was to describe reasons of MS treatment modifications in a large cohort of Italian MS patients. METHODS: this multicenter, cross-sectional non interventional study (SWITCH) conducted at 28 Italian MS centers, screened, by visit/telephone contact between June 2016 and June 2017, all RRMS patients receiving stable DMT treatment and enrolled patients with change in DMT treatment. RESULTS: out of 13,657 recorded in the log, 409 (3%) changed therapy. Of these, 336 (2.5%), met the study criteria and were considered eligible. Among 303 (90.2% of 336) patients switching, the most common reason was "lack of efficacy" (58.4% of 303). Among 30 (8.9%) patients who interrupted treatment temporarily, the most common reason was pregnancy (40.0% of 30). Out of 3 (0.9%) patients who discontinued treatment permanently, 2 (66.7%) had as first reason as "patient decision". Multivariate analysis showed that EDSS was the only variable with statistically significant effect on changing treatments (r = 8.33; p-value of Type III Sum of Squares = 0.016). CONCLUSION: in our study, 303 (90.2% of eligible patients) switched treatment, 30 (8.9%) interrupted treatment temporarily, and 3 (0.9%) discontinued treatment permanently. Efficacy remains the main driving force behind switching behavior, as the primary aim of treatment is to be disease free or reduce disease activity.

RESUMO

INTRODUCTION: Depression and anxiety are common among patients with multiple sclerosis (MS) and are frequently present at the time of MS diagnosis. METHODS: POSIDONIA was a 12-month, observational, prospective study conducted in Italy to evaluate the impact of disease-modifying treatment (DMT) on emotional burden in patients with recently-diagnosed MS. The Hospital Anxiety and Depression Scale (HADS), specifically HADS anxiety (HADS-A) and depression (HADS-D) subscale scores, the Short-Form 36 Health Survey (SF-36) and the Impact of Event Scale - Revised (IES-R) were used to measure patient-reported outcomes. The Hamilton Depression Rating Scale (HDRS), HDRS-17, was used as a measure of healthcare provider-reported outcomes. The primary study outcome was change from baseline in feelings of anxiety and depression over 12months (via HADS). RESULTS: Of 250 enrolled patients, 222 (88.8%) completed the study. At baseline, mean HADS total, HADS-A and HADS-D subscale scores were within the normal range. There were no significant changes over time in mean HADS total and HADS-A and HADS-D subscale scores, although the subgroup of patients with baseline scores indicative of anxiety or depression tended to improve over time. Both the HDRS and IES-R total scores improved over time, but there were no statistically significant changes in SF-36. CONCLUSION: In the patient population of the POSIDONIA study depression and anxiety were present in a minority of patients thus not allowing to detect the impact of starting DMT. However DMT appears to have a positive effect in patients with measurable anxiety or depression at baseline.

RESUMO

The presence of Epstein-Barr Virus (EBV) DNA in cerebrospinal fluid (CSF) and peripheral blood (PB) samples collected from 55 patients with clinical and radiologically-active relapsing-remitting MS (RRMS) and 51 subjects with other neurological diseases was determined using standardized commercially available kits for viral nucleic acid extraction and quantitative EBV DNA detection. Both cell-free and cell-associated CSF and PB fractions were analyzed, to distinguish latent from lytic EBV infection. EBV DNA was detected in 5.5% and 18.2% of cell-free and cell-associated CSF fractions of patients with RRMS as compared to 7.8% and 7.8% of controls; plasma and peripheral blood mononuclear cells (PBMC) positivity rates were 7.3% and 47.3% versus 5.8% and 31.4%, respectively. No significant difference in median EBV viral loads of positive samples was found between RRMS and control patients in all tested samples. Absence of statistically significant differences in EBV positivity rates between RRMS and control patients, despite the use of highly sensitive standardized methods, points to the lack of association between EBV and MS disease activity.

RESUMO

Pixantrone is an immunesuppressor similar to mitoxantrone but with lower cardiotoxicity. We evaluated the effect of pixantrone on B cells and lymphomononuclear cells in the course of acute EAE. Pixantrone reduced the number of B cells and suppressed myelin basic protein (MBP) specific IgG production. In vitro, pixantrone induced apoptosis of rat B lymphocytes in a way similar to mitoxantrone. In addition, pixantrone inhibited antigen specific and mitogen induced lymphomononuclear cell proliferation, as well as IFN-gamma production, during EAE. These findings suggest a similar mechanism of action for pixantrone and mitoxantrone on the effector function of lymphomonocyte B and T cells.
