    CONCLUSION: ^(11)C-PBR28 imaging reveals more active WM lesions than 7T PRL assessment. Although PRL and PET active lesion counts are related, neurological disability is better explained by PET whole active lesion volume.
  • Cervical spondylosis is a risk factor for localized spinal cord lesions in multiple sclerosis

    jueves, octubre 22, 2020
    Author(s): Roberto Bomprezzi,Andrew P Chen,Christopher C Hemond
    Source: Clinical neurology and neurosurgery
    CONCLUSIONS: The data from our cohort of MS patients suggest an indirect contribution of cervical spondylosis to disability by increasing the risk of developing localized cord lesions. While further studies are needed to confirm the findings and clarify disease mechanisms, closer attention should be paid to worsening spondylosis in patients with MS.
  • Are randomized, blind clinical trials enough to guide individualized decisions for patients with neurologic diseases?

    sábado, febrero 24, 2018
    Author(s): Yazan J Alderazi,Roberto Bomprezzi
    Source: Neurology. Clinical practice
    The practice of medicine relies on the patient-physician relationship, knowledge, and clinical judgment. Randomized controlled trials (RCTs) remain the least biased method for studying the effects of interventions in selected populations and are the only method to control adequately for unknown confounders. However, physicians face the limitations of RCTs on a daily basis as they treat relatively unselected populations and individual patients. We explore the benefits and limitations of RCTs for...

    A comprehensive analysis of the effect of lesion in-painting on the estimation of cortical thickness using magnetic resonance imaging was performed on a large cohort of 918 relapsing-remitting multiple sclerosis patients who participated in a phase III multicenter clinical trial. An automatic lesion in-painting algorithm was developed and implemented. Cortical thickness was measured using the FreeSurfer pipeline with and without in-painting. The effect of in-painting was evaluated using...
  • Regional gray matter atrophy in relapsing remitting multiple sclerosis: baseline analysis of multi-center data

    viernes, marzo 20, 2015
    Author(s): Sushmita Datta,Terrell D Staewen,Stacy S Cofield,Gary R Cutter,Fred D Lublin,Jerry S Wolinsky,Ponnada A Narayana,MRI Analysis Center at Houston,CombiRx Investigators Group
    Source: Multiple sclerosis and related disorders
    Regional gray matter (GM) atrophy in multiple sclerosis (MS) at disease onset and its temporal variation can provide objective information regarding disease evolution. An automated pipeline for estimating atrophy of various GM structures was developed using tensor based morphometry (TBM) and implemented on a multi-center sub-cohort of 1008 relapsing remitting MS (RRMS) patients enrolled in a Phase 3 clinical trial. Four hundred age and gender matched healthy controls were used for comparison....
  • Effects of delayed-release dimethyl fumarate on MRI measures in the phase 3 CONFIRM study

    domingo, febrero 15, 2015
    Author(s): David H Miller,Robert J Fox,J Theodore Phillips,Michael Hutchinson,Eva Havrdova,Mariko Kita,Claudia A M Wheeler-Kingshott,Daniel J Tozer,David G MacManus,Tarek A Yousry,Mary Goodsell,Minhua Yang,Ray Zhang,Vissia Viglietta,Katherine T Dawson,CONFIRM study investigators

    CONCLUSIONS: The robust effects on MRI active lesion counts and total lesion volume in patients with RRMS demonstrate the ability of DMF to exert beneficial effects on inflammatory lesion activity in multiple sclerosis, and support DMF therapy as a valuable new treatment option in RRMS.
  • Dimethyl fumarate in the treatment of relapsing-remitting multiple sclerosis: an overview

    miércoles, enero 14, 2015
    Author(s): Roberto Bomprezzi
    Source: Therapeutic advances in neurological disorders
    Multiple sclerosis (MS) shares an immune-mediated origin with psoriasis. Long-term safety and efficacy data generated in Europe from usage of fumaric acid formulations in the latter disease constituted grounds to investigate their effects in MS patients. Dimethyl fumarate (DMF) was found to be the active principle in those formulations and in vitro studies have demonstrated that DMF has immune-modulatory properties exerted through abilities to divert cytokine production toward a Th2 profile,...
  • Extended interval dosing of natalizumab: a two-center, 7-year experience

    sábado, octubre 25, 2014
    Author(s): Roberto Bomprezzi,Siddharama Pawate
    Source: Therapeutic advances in neurological disorders
    CONCLUSION: Natalizumab is effective in controlling MS as very few clinical relapses were observed in our dataset. We found that EID did not compromise the treatment effect as measured by relapse rate and no significant breakthrough disease activity was observed. EID is an optional regimen for maintenance natalizumab therapy, but prospective studies are warranted to determine its efficacy.

    There has been a growing interest in using next-generation sequencing (NGS) to profile extracellular small RNAs from the blood and cerebrospinal fluid (CSF) of patients with neurological diseases, CNS tumors, or traumatic brain injury for biomarker discovery. Small sample volumes and samples with low RNA abundance create challenges for downstream small RNA sequencing assays. Plasma, serum, and CSF contain low amounts of total RNA, of which small RNAs make up a fraction. The purpose of this study...
