Comparative effectiveness research (CER) has been proposed as a framework to provide evidence for optimal care for TBI patients. The first step in CER is to map the existing variation. The aim of current study is to quantify variation in general structural and process characteristics among centers participating in the Collaborative European NeuroTrauma Effectiveness Research in Traumatic Brain Injury (CENTER-TBI) study. Methods: We designed a set of 11 provider profiling questionnaires with 321 questions about various aspects of TBI care, chosen based on literature and expert opinion. After pilot testing, questionnaires were disseminated to 71 centers from 20 countries participating in the CENTER-TBI study. Reliability of questionnaires was estimated by calculating a concordance rate among 5% duplicate questions. Results: All 71 centers completed the questionnaires. Median concordance rate among duplicate questions was 0.85. The majority of centers were academic hospitals (n = 65, 92%), designated as a level I trauma center (n = 48, 68%) and situated in an urban location (n = 70, 99%). The availability of facilities for neuro-trauma care varied across centers; e.g. 40 (57%) had a dedicated neuro-intensive care unit (ICU), 36 (51%) had an in-hospital rehabilitation unit and the organization of the ICU was closed in 64% (n = 45) of the centers. In addition, we found wide variation in processes of care, such as the ICU admission policy and intracranial pressure monitoring policy among centers. Conclusion: Even among high-volume, specialized neurotrauma centers there is substantial variation in structures and processes of TBI care. This variation provides an opportunity to study effectiveness of specific aspects of TBI care and to identify best practices with CER approaches.

Abstract

Source at https://doi.org/10.1186/s13054-018-2241-4. Licensed CC BY-NC-ND 4.0. Background: We aimed to investigate the extent of the agreement on practices around brain death and postmortem organ donation. Methods: Investigators from 67 Collaborative European NeuroTrauma Effectiveness Research in Traumatic Brain Injury (CENTER-TBI) study centers completed several questionnaires (response rate: 99%). Results: Regarding practices around brain death, we found agreement on the clinical evaluation (prerequisites and neurological assessment) for brain death determination (BDD) in 100% of the centers. However, ancillary tests were required for BDD in 64% of the centers. BDD for nondonor patients was deemed mandatory in 18% of the centers before withdrawing life-sustaining measures (LSM). Also, practices around postmortem organ donation varied. Organ donation after circulatory arrest was forbidden in 45% of the centers. When withdrawal of LSM was contemplated, in 67% of centers the patients with a ventricular drain in situ had this removed, either sometimes or all of the time. Conclusions: This study showed both agreement and some regional differences regarding practices around brain death and postmortem organ donation. We hope our results help quantify and understand potential differences, and provide impetus for current dialogs toward further harmonization of practices around brain death and postmortem organ donation.

Abstract

BACKGROUND: The availability of interventions for bereaved parents have increased. However, most are practice based. To enhance the implementation of bereavement care for parents, an overview of interventions which are replicable and evidence-based are needed. The aim of this review is to provide an overview of well-defined bereavement interventions, focused on the parents, and delivered by regular health care professionals. Also, we explore the alignment between the interventions identified and the concepts contained in theories on grief in order to determine their theoretical evidence base. METHOD: A systematic review was conducted using the methods PALETTE and PRISMA. The search was conducted in MEDLINE, Embase, and CINAHL. We included articles containing well-defined, replicable, paediatric bereavement interventions, focused on the parent, and performed by regular health care professionals. We excluded interventions on pathological grief, or interventions performed by healthcare professionals specialised in bereavement care. Quality appraisal was evaluated using the risk of bias, adapted risk of bias, or COREQ. In order to facilitate the evaluation of any theoretical foundation, a synthesis of ten theories about grief and loss was developed showing five key concepts: anticipatory grief, working models or plans, appraisal processes, coping, and continuing bonds. RESULTS: Twenty-one articles were included, describing fifteen interventions. Five overarching components of intervention were identified covering the content of all interventions. These were: the acknowledgement of parenthood and the child's life; establishing keepsakes; follow-up contact; education and information, and; remembrance activities. The studies reported mainly on how to conduct, and experiences with, the interventions, but not on their effectiveness. Since most interventions lacked empirical evidence, they were evaluated against the key theoretical concepts which showed that all the components of intervention had a theoretical base. CONCLUSIONS: In the absence of empirical evidence supporting the effectiveness of most interventions, their alignment with theoretical components shows support for most interventions on a conceptual level. Parents should be presented with a range of interventions, covered by a variety of theoretical components, and aimed at supporting different needs. Bereavement interventions should focus more on the continuous process of the transition parents experience in readjusting to a new reality. TRIAL REGISTRATION: This systematic review was registered in Prospero (registration number: CRD42019119241).

26. Associations with autoimmune disorders and HLA class I and II antigens in inclusion body myositis

Abstract

Whether autoimmune mechanisms play a role in the pathogenesis of inclusion body myositis (IBM) is unknown. Human leukocyte antigen (HLA) analysis in 52 patients, including 17 with autoimmune disorders (AIDs), showed that patients were more likely to have antigens from the autoimmune-prone HLA-B8-DR3 ancestral haplotype than healthy control subjects, irrespective of the presence of AIDs. Patients lacked the apparently protective HLA-DR53 antigen. The results provide further support for an autoimmune basis in IBM.

Abstract

Background No definitive evidence exists on how intracranial hypertension should be treated in patients with traumatic brain injury (TBI). It is therefore likely that centers and practitioners individually balance potential benefits and risks of different intracranial pressure (ICP) management strategies, resulting in practice variation. The aim of this study was to examine variation in monitoring and treatment policies for intracranial hypertension in patients with TBI. Methods A 29-item survey on ICP monitoring and treatment was developed on the basis of literature and expert opinion, and it was pilot-tested in 16 centers. The questionnaire was sent to 68 neurotrauma centers participating in the Collaborative European Neurotrauma Effectiveness Research in Traumatic Brain Injury (CENTER-TBI) study. Results The survey was completed by 66 centers (97% response rate). Centers were mainly academic hospitals (n = 60, 91%) and designated level I trauma centers (n = 44, 67%). The Brain Trauma Foundation guidelines were used in 49 (74%) centers. Approximately 90% of the participants (n = 58) indicated placing an ICP monitor in patients with severe TBI and computed tomographic abnormalities. There was no consensus on other indications or on peri-insertion precautions. We found wide variation in the use of first- and second-tier treatments for elevated ICP. Approximately half of the centers were classified as using a relatively aggressive approach to ICP monitoring and treatment (n = 32, 48%), whereas the others were considered more conservative (n = 34, 52%). Conclusions Substantial variation was found regarding monitoring and treatment policies in patients with TBI and intracranial hypertension. The results of this survey indicate a lack of consensus between European neurotrauma centers and provide an opportunity and necessity for comparative effectiveness research.

Abstract

Objective: Antiseizure medication may have long-term effects on the neurodevelopment of children. We aimed to investigate the association between cumulative antiseizure medication load and intelligence quotient (IQ) in relation to brain volume and cortical thickness., Methods: A retrospective analysis of children with focal epilepsy who underwent neuropsychological assessment and MRI between the ages of 5-12 years in a tertiary epilepsy centre was performed. Cumulative medication load was presented in medication years. We studied the association between total medication load and IQ with multivariable linear regression, corrected for epilepsy-related confounders: age at first treatment, aetiology, maximum seizure frequency, duration of active epilepsy, history of secondary generalized seizures, history of status epilepticus, and the number of antiseizure medications used at time of neuropsychological assessment., Results: We included 59 children. Median medication load was 5.3 medication-years (interquartile range: 2.0 – 11.1) and mean total IQ (± standard deviation) was 77.4±18.9. A significant negative relation between medication load and total IQ was found with a decrease of 1.2 IQ-points per medication-year (95% confidence interval: -2.0 to -0.3) after correcting for confounders. Medication load and IQ were both not significantly associated with brain volume or cortical thickness., Significance: Higher cumulative medication load is associated with lower total IQ after adjusting for epilepsy-related confounders. We found no evidence to support the hypothesis that the medication-related IQ decrease was mediated by volumetric brain changes. However, these results should be interpreted with caution, and prospective, longitudinal confirmation of these findings is required. Lastly, it should be stressed that effective seizure prevention often outweighs the potential negative effects of antiseizure medication.

Abstract

Background: The availability of interventions for bereaved parents have increased. However, most are practice based. To enhance the implementation of bereavement care for parents, an overview of interventions which are replicable and evidence-based are needed. The aim of this review is to provide an overview of well-defined bereavement interventions, focused on the parents, and delivered by regular health care professionals. Also, we explore the alignment between the interventions identified and the concepts contained in theories on grief in order to determine their theoretical evidence base., Method: A systematic review was conducted using the methods PALETTE and PRISMA. The search was conducted in MEDLINE, Embase, and CINAHL. We included articles containing well-defined, replicable, paediatric bereavement interventions, focused on the parent, and performed by regular health care professionals. We excluded interventions on pathological grief, or interventions performed by healthcare professionals specialised in bereavement care. Quality appraisal was evaluated using the risk of bias, adapted risk of bias, or COREQ. In order to facilitate the evaluation of any theoretical foundation, a synthesis of ten theories about grief and loss was developed showing five key concepts: anticipatory grief, working models or plans, appraisal processes, coping, and continuing bonds., Results: Twenty-one articles were included, describing fifteen interventions. Five overarching components of intervention were identified covering the content of all interventions. These were: the acknowledgement of parenthood and the child's life; establishing keepsakes; follow-up contact; education and information, and; remembrance activities. The studies reported mainly on how to conduct, and experiences with, the interventions, but not on their effectiveness. Since most interventions lacked empirical evidence, they were evaluated against the key theoretical concepts which showed that all the components of intervention had a theoretical base., Conclusions: In the absence of empirical evidence supporting the effectiveness of most interventions, their alignment with theoretical components shows support for most interventions on a conceptual level. Parents should be presented with a range of interventions, covered by a variety of theoretical components, and aimed at supporting different needs. Bereavement interventions should focus more on the continuous process of the transition parents experience in readjusting to a new reality., Trial Registration: This systematic review was registered in Prospero (registration number: CRD42019119241).

Abstract

Objective: The study is aimed at widening the clinical and genetic spectrum and at assessing genotype-phenotype associations in QARS encephalopathy., Methods: Through diagnostic gene panel screening in an epilepsy cohort, and recruiting through GeneMatcher and our international network, we collected 10 patients with biallelic QARS variants. In addition, we collected data on 12 patients described in the literature to further delineate the associated phenotype in a total cohort of 22 patients. Computer modeling was used to assess changes on protein folding., Results: Biallelic pathogenic variants in QARS cause a triad of progressive microcephaly, moderate to severe developmental delay, and early-onset epilepsy. Microcephaly was present at birth in 65%, and in all patients at follow-up. Moderate (14%) or severe (73%) developmental delay was characteristic, with no achievement of sitting (85%), walking (86%), or talking (90%). Additional features included irritability (91%), hypertonia/spasticity (75%), hypotonia (83%), stereotypic movements (75%), and short stature (56%). Seventy-nine percent had pharmacoresistant epilepsy with mainly neonatal onset. Characteristic cranial MRI findings include early-onset progressive atrophy of cerebral cortex (89%) and cerebellum (61%), enlargement of ventricles (95%), and age-dependent delayed myelination (88%). A small subset of patients displayed a less severe phenotype., Conclusions: These data revealed first genotype-phenotype associations and may serve for improved interpretation of new QARS variants and well-founded genetic counseling., (Copyright © 2019 The Author(s).

Abstract

Phenotypic and biochemical categorization of humans with detrimental variants can provide valuable information on gene function. We illustrate this with the identification of two different homozygous variants resulting in enzymatic loss-of-function in LDHD, encoding lactate dehydrogenase D, in two unrelated patients with elevated D-lactate urinary excretion and plasma concentrations. We establish the role of LDHD by demonstrating that LDHD loss-of-function in zebrafish results in increased concentrations of D-lactate. D-lactate levels are rescued by wildtype LDHD but not by patients' variant LDHD, confirming these variants' loss-of-function effect. This work provides the first in vivo evidence that LDHD is responsible for human D-lactate metabolism. This broadens the differential diagnosis of D-lactic acidosis, an increasingly recognized complication of short bowel syndrome with unpredictable onset and severity. With the expanding incidence of intestinal resection for disease or obesity, the elucidation of this metabolic pathway may have relevance for those patients with D-lactic acidosis.

Abstract

Following the results of the multicentre European retrospective "TimeToStop" cohort study, we initiated a randomised trial to determine cognitive benefits of early postoperative antiepileptic drug withdrawal. Unfortunately, the trial failed to recruit and was terminated, as almost all parents preferred early drug withdrawal. The objectives of the current survey were to obtain insight into current practices regarding drug withdrawal after paediatric epilepsy surgery among epileptologists, and better understand the reasons for difficulties in recruitment. A survey was sent to three international epilepsy surgery networks, questioning drug withdrawal policies. Forty-seven (19%) surveys were returned. For polytherapy, withdrawal was started at a median of three and six months by the TimeToStop collaborators and other paediatric epileptologists, respectively. Withdrawal was completed at a median of 12 and 20 months, respectively. For monotherapy, tapering was initiated at five and 11 months in these two groups, and ended at a median of seven and 12 months, respectively. Most TimeToStop collaborators believed that it was not justified to wait 12 months after surgery before reducing AEDs, regardless of the number of AEDs taken. Current AED policies in Europe have changed as a consequence of the retrospective TimeToStop results, and this accounts for why recruitment in a randomised trial was not feasible.

Abstract

The objective of this study was to create a clinically useful tool for individualized prediction of seizure outcomes following antiepileptic drug withdrawal after pediatric epilepsy surgery. We used data from the European retrospective TimeToStop study, which included 766 children from 15 centers, to perform a proportional hazard regression analysis. The 2 outcome measures were seizure recurrence and seizure freedom in the last year of follow-up. Prognostic factors were identified through systematic review of the literature. The strongest predictors for each outcome were selected through backward selection, after which nomograms were created. The final models included 3 to 5 factors per model. Discrimination in terms of adjusted concordance statistic was 0.68 (95% confidence interval [CI] 0.67-0.69) for predicting seizure recurrence and 0.73 (95% CI 0.72-0.75) for predicting eventual seizure freedom. An online prediction tool is provided on www.epilepsypredictiontools.info/ttswithdrawal. The presented models can improve counseling of patients and parents regarding postoperative antiepileptic drug policies, by estimating individualized risks of seizure recurrence and eventual outcome., (Wiley Periodicals, Inc. © 2018 International League Against Epilepsy.)

Abstract

Background: People with epilepsy who became seizure-free while taking antiepileptic drugs might consider discontinuing their medication, with the possibility of increased quality of life because of the elimination of adverse events. The risk with this action, however, is seizure recurrence. The objectives of our study were to identify predictors of seizure recurrence and long-term seizure outcomes and to produce nomograms for estimation of individualised outcomes., Methods: We did a systematic review and meta-analysis, and identified eligible articles and candidate predictors, using PubMed and Embase databases with a last update on Nov 6, 2014. Eligible articles had to report on cohorts of patients with epilepsy who were seizure-free and had started withdrawal of antiepileptic drugs; articles also had to contain information regarding seizure recurrences during and after withdrawal. We excluded surgical cohorts, reports with fewer than 30 patients, and reports on acute symptomatic seizures because these topics were beyond the scope of our objective. Risk of bias was assessed using the Quality in Prognosis Studies system. Data analysis was based on individual participant data. Survival curves and proportional hazards were computed. The strongest predictors were selected with backward selection. Models were converted to nomograms and a web-based tool to determine individual risks., Findings: We identified 45 studies with 7082 patients; ten studies (22%) with 1769 patients (25%) were included in the meta-analysis. Median follow-up was 5·3 years (IQR 3·0-10·0, maximum 23 years). Prospective and retrospective studies and randomised controlled trials were included, covering non-selected and selected populations of both children and adults. Relapse occurred in 812 (46%) of 1769 patients; 136 (9%) of 1455 for whom data were available had seizures in their last year of follow-up, suggesting enduring seizure control was not regained by this timepoint. Independent predictors of seizure recurrence were epilepsy duration before remission, seizure-free interval before antiepileptic drug withdrawal, age at onset of epilepsy, history of febrile seizures, number of seizures before remission, absence of a self-limiting epilepsy syndrome, developmental delay, and epileptiform abnormality on electroencephalogram (EEG) before withdrawal. Independent predictors of seizures in the last year of follow-up were epilepsy duration before remission, seizure-free interval before antiepileptic drug withdrawal, number of antiepileptic drugs before withdrawal, female sex, family history of epilepsy, number of seizures before remission, focal seizures, and epileptiform abnormality on EEG before withdrawal. Adjusted concordance statistics were 0·65 (95% CI 0·65-0·66) for predicting seizure recurrence and 0·71 (0·70-0·71) for predicting long-term seizure freedom. Validation was stable across the individual study populations., Interpretation: We present evidence-based nomograms with robust performance across populations of children and adults. The nomograms facilitate prediction of outcomes following drug withdrawal for the individual patient, including both the risk of relapse and the chance of long-term freedom from seizures. The main limitations were the absence of a control group continuing antiepileptic drug treatment and a consistent definition of long-term seizure freedom., Funding: Epilepsiefonds., (Copyright © 2017 Elsevier Ltd.

Abstract

Hashimoto encephalopathy is a rare condition, characterized by the association of encephalopathy with a variety of neurological symptoms and autoantibodies to the thyroid gland. Its etiology is unknown, and symptoms are usually treated with immune suppressive therapy, e.g., high doses of corticosteroids., Methods and Results: Here, we report the long-term outcome in two steroid-refractory adolescents with Hashimoto encephalopathy who were treated with rituximab, a monoclonal antibody directed against CD20. In addition, we reviewed the literature regarding treatment strategies in Hashimoto encephalopathy., Conclusions: Anti-B-cell therapy can be of value in the treatment of Hashimoto encephalopathy, especially in steroid refractory cases, but side effects due to low levels of immunoglobulins warrant careful monitoring., (Copyright © 2016 Elsevier Inc.

Abstract

Background: The goals of intentional curative pediatric epilepsy surgery are to achieve seizure-freedom and antiepileptic drug (AED) freedom. Retrospective cohort studies have indicated that early postoperative AED withdrawal unmasks incomplete surgical success and AED dependency sooner, but not at the cost of long-term seizure outcome. Moreover, AED withdrawal seemed to improve cognitive outcome. A randomized trial is needed to confirm these findings. We hypothesized that early AED withdrawal in children is not only safe, but also beneficial with respect to cognitive functioning., Design: This is a multi-center pragmatic randomized clinical trial to investigate whether early AED withdrawal improves cognitive function, in terms of attention, executive function and intelligence, quality of life and behavior, and to confirm safety in terms of eventual seizure freedom, seizure recurrences and "seizure and AED freedom." Patients will be randomly allocated in parallel groups (1:1) to either early or late AED withdrawal. Randomization will be concealed and stratified for preoperative IQ and medical center. In the early withdrawal arm reduction of AEDs will start 4 months after surgery, while in the late withdrawal arm reduction starts 12 months after surgery, with intended complete cessation of drugs after 12 and 20 months respectively. Cognitive outcome measurements will be performed preoperatively, and at 1 and 2 years following surgery, and consist of assessment of attention and executive functioning using the EpiTrack Junior test and intelligence expressed as IQ (Wechsler Intelligence Scales). Seizure outcomes will be assessed at 24 months after surgery, and at 20 months following start of AED reduction. We aim to randomize 180 patients who underwent anticipated curative epilepsy surgery below 16 years of age, were able to perform the EpiTrack Junior test preoperatively, and have no predictors of poor postoperative seizure prognosis (multifocal magnetic resonance imaging (MRI) abnormalities, incomplete resection of the lesion, epileptic postoperative electroencephalogram (EEG) abnormalities, or more than three AEDs at the time of surgery)., Discussion: Growing experience with epilepsy surgery has changed the view towards postoperative medication policy. In a European collaboration, we designed a multi-center pragmatic randomized clinical trial comparing early with late AED withdrawal to investigate benefits and safety of early AED withdrawal. The TTS trial is supported by the Dutch Epilepsy Fund (NL 08-10) ISRCTN88423240/ 08/05/2013.

Objective: Guillain-Barré syndrome (GBS) is a postinfectious neuropathy most frequently caused by Campylobacter jejuni. Lipo-oligosaccharides (LOS), expressed by C. jejuni induce antibodies that cross-react with self-glycolipids in peripheral nerves, causing neuropathy. Less than 1 in 1,000 persons infected with C. jejuni develop GBS, and the factors that determine GBS susceptibility are poorly understood. We hypothesized that these persons have a high intrinsic dendritic cell (DC) response to C. jejuni LOS through Toll-like receptor 4 (TLR4) activation., Methods: Intrinsic DC responsiveness to C. jejuni LOS was investigated first in 20 healthy controls at three time points with a 3-month interval, and second in patients, who previously developed GBS after a C. jejuni infection (n = 27) and controls (n = 26)., Results: The DC response to C. jejuni LOS was highly variable between, but not within, healthy individuals, suggesting that intrinsic factors determine the magnitude of TLR4-mediated innate response. High responsiveness to C. jejuni LOS by former GBS patients was evidenced by increased expression of CD38 and CD40. Frequency of CD38, CD40 and type I interferon high responders was significantly increased in the GBS group., Interpretation: These results suggest that a strong response to TLR4 stimulation is a critical host condition for the development of GBS after an infection with C. jejuni., (© 2015 American Neurological Association.)

Abstract

Aim: Many seizure-free patients consider withdrawal of antiepileptic drugs, both when seizure control is achieved by medication alone, or once they became seizure-free following epilepsy surgery. The risk of recurrence is consequently of very important prognostic value. However, estimations of recurrence risks are outdated for both populations. In addition, although many publications have reported predictors of seizure relapse, no comprehensive overview of prognostic factors is available., Methods: A systematic review of the databases of PubMed and EMBASE was conducted, identifying articles on antiepileptic drug withdrawal in patient cohorts. Recurrence risk meta-analyses were performed for both populations at one, two, three to four, and five or more years of follow-up. Within the selected articles, studies presenting multivariable analysis of predictors were identified; all studied predictors were listed, as well as all significant independent predictors. The quality of separate analyses of predictors was assessed., Results: There was no significant difference of long-term cumulative recurrence risk between surgical and medication-only populations, with respectively 29% and 34% recurrences. In medication-only treated patients, 25 factors have been reported as significant independent predictors; 12 have been reported in surgical cohorts. The quality of most analyses of predictors was low to moderate. No predictor was consistently found among all analyses, and for most predictors, study results were contradictory., Conclusion: No consistent set of predictors could be identified because a large number of variables have been identified in the literature, many studies reported contradicting results, study populations varied considerably, and the quality of the original studies was often low. Meta-analysis of individual participant data is necessary, because it allows for (1) correction for differences in follow-up duration between subjects and studies, (2) a study of interaction effects, (3) calculation of more accurate estimates valid across several populations, and (4) the assessment of each predictor's effect size.

Abstract

Immune responses to microbial glycolipids that cross-react to neural epitopes may trigger the Guillain-Barré syndrome (GBS). CD1 molecules are involved in antigen presentation of glycolipids and variation in CD1 genes was recently reported to confer susceptibility to develop GBS. This hypothesis was tested by comparing single nucleotide polymorphisms (SNPs) of CD1A and CD1E in 312 well defined GBS patients and 212 healthy controls. SNPs in CD1A and CD1E were not associated with GBS susceptibility, specific clinical subgroups, anti-ganglioside antibodies, antecedent infections and prognosis. Based on this study, CD1 polymorphisms are not a susceptibility or disease modifying factor in GBS.

Abstract

In 176 patients with Guillain-Barré syndrome the subclass and cross-reactivity of serum IgG antibodies to motor gangliosides was related to preceding infections and clinical phenotypes. Two subgroups of patients were identified. Presence of only IgG1 antibodies was related to diarrhea, positive Campylobacter serology, cross-reactive antibodies to C. jejuni lipo-oligosaccharides and poor outcome. In contrast, having both IgG1 and IgG3 antibodies was related to upper respiratory tract infections, cross-reactive antibodies to Haemophilus influenzae lipo-oligosaccharides and better outcome. These findings support a model in which C. jejuni and H. influenzae infections induce two distinct patterns of cross-reactive antibodies with different clinical outcome.

Abstract

Macrophages infiltrate peripheral nerves and may contribute to neural damage in the Guillain-Barré syndrome (GBS). We determined whether single nucleotide polymorphisms (SNP) in genes encoding macrophage-mediators are related to the susceptibility and severity of GBS. The frequencies of SNP in the TNFA, MMP9, IL10, and NOS2a genes did not differ between 263 GBS patients and 210 healthy subjects. The MMP9 C(-1562)T and TNFA C(-863)A SNP were associated with severe weakness and poor outcome, indicating that these SNP may be one of the factors predisposing to a severe form of GBS.

Abstract

In Guillain-Barré syndrome (GBS), complement activation plays a crucial role in the induction and extent of the postinfectious immune-mediated peripheral nerve damage. Mannose-binding lectin (MBL) activates the complement system via the lectin pathway after recognition of repetitive sugar groups on pathogens. We investigated whether the MBL2 genotype, serum MBL level, and MBL complex activity are associated with the development and severity of GBS. Single nucleotide polymorphisms in the promoter region (-550 H/L and -221 X/Y) and exon 1 (A/O) of the MBL2 gene were determined in 271 GBS patients and 212 healthy controls. The frequencies of the H allele, HY promoter haplotype, and HYA haplotype, which are related to high MBL activity, were all increased in GBS patients compared with healthy controls (p < or = 0.03), particularly in severely affected GBS patients (MRC-sum score < 40) (p < or = 0.02). Severe weakness was also associated with high MBL concentrations and MBL complex activity in sera from GBS patients (p < 0.01). The MBL2 B allele was associated with functional deficiency and relatively mild weakness. These results support the hypothesis that complement activation mediated by MBL contributes to the extent of nerve damage in GBS, which is codetermined by the MBL2 haplotype.

Abstract

The Inflammatory Neuropathy and Treatment (INCAT) group developed a standardized ELISA method for the detection of serum anti-GM1 antibodies. The diagnostic value of anti-GM1 antibodies determined by this method has not yet been established in large groups of patients. We assessed the reproducibility, sources of variation, optimal cut-off values and evaluated the diagnostic relevance of the INCAT-ELISA in various groups of patients and controls (N=1232). The coefficient of variance was 11.2% for IgM and 3.8% for IgG. High IgG titers were only found in Guillain-Barré syndrome (GBS) and other inflammatory polyneuropathies. High IgM titers were associated with GBS and multifocal motor neuropathy. Low IgM titers had no additional diagnostic value. The INCAT-ELISA is a reliable test with additional diagnostic value in specific clinical situations.

Abstract

Polymorphisms in genes involved in regulation of immune homeostasis may be a susceptibility factor in the induction of cross-reactive anti-ganglioside antibodies after infection in patients with Guillain-Barre syndrome (GBS). In this study we assessed whether polymorphisms in the promoter region of Fas and FasL and sFas and sFasL are related to GBS or its distinct clinical or serological subgroups. We show that the A(-670)G SNP in the promoter region of Fas and high levels of sFas are associated with the presence of anti-ganglioside antibodies, suggesting that Fas-FasL interaction is involved in the production of cross-reactive antibodies in GBS.

Abstract

It remains unknown if and how the polyethylene bearing in mobile bearing knees moves during dynamic activities with respect to the tibial base plate. Marker Configuration Model-Based Roentgen Fluoroscopic Analysis (MCM-based RFA) uses a marker configuration model of inserted tantalum markers in order to accurately estimate the pose of an implant or bone using single plane Roentgen images or fluoroscopic images. The goal of this study is to assess the accuracy of (MCM-Based RFA) in a standard fluoroscopic set-up using phantom experiments and to determine the error propagation with computer simulations. The experimental set-up of the phantom study was calibrated using a calibration box equipped with 600 tantalum markers, which corrected for image distortion and determined the focus position. In the computer simulation study the influence of image distortion, MC-model accuracy, focus position, the relative distance between MC-models and MC-model configuration on the accuracy of MCM-Based RFA were assessed. The phantom study established that the in-plane accuracy of MCM-Based RFA is 0.1 mm and the out-of-plane accuracy is 0.9 mm. The rotational accuracy is 0.1 degrees. A ninth-order polynomial model was used to correct for image distortion. Marker-Based RFA was estimated to have, in a worst case scenario, an in vivo translational accuracy of 0.14 mm (x-axis), 0.17 mm (y-axis), 1.9 mm (z-axis), respectively, and a rotational accuracy of 0.3 degrees. When using fluoroscopy to study kinematics, image distortion and the accuracy of models are important factors, which influence the accuracy of the measurements. MCM-Based RFA has the potential to be an accurate, clinically useful tool for studying kinematics after total joint replacement using standard equipment.

Abstract

Purpose: To evaluate multi-detector row computed tomographic (CT) depiction of pulmonary veins to provide a road map for radiofrequency catheter ablation., Materials and Methods: For patients, institutional review board (IRB) approval was not required, and consent was obtained for treatment. Control subjects were part of an IRB-approved research protocol at the institution, in which they had consented to participate. Multi-detector row CT was performed in 23 patients (17 men, six women; mean age, 48 years +/- 11 [standard deviation]) with atrial fibrillation who were admitted for isolation of pulmonary veins by means of radiofrequency catheter ablation. Pulmonary vein anatomy was evaluated, and diameters of pulmonary vein ostia were measured. To determine the shape of ostia, a venous ostium index was calculated for all veins by dividing anterior-posterior measurements by superior-inferior measurements. Results were compared with those in a control group of 11 patients (eight men, three women; mean age, 56 years +/- 11) without atrial fibrillation. Images were evaluated by two observers in consensus., Results: Pulmonary veins additional to the four main veins were found in seven (30%) of 23 patients. Common ostia of left and right pulmonary veins were detected in 19 (83%) and nine (39%) patients, respectively. Early branching occurred more often with right than with left veins (19 [83%] vs three [13%] cases, P <.05) in both patients and control subjects. Anterior-posterior diameter of ostia was 12.8 mm +/- 3.3 for left veins, 16.2 mm +/- 3.8 for right veins, and 18.8 mm +/- 7.7 and 28.7 mm +/- 5.1 for left and right common ostia, respectively. Ostia of right pulmonary veins were more round than were ostia of left pulmonary veins (venous ostium index in patients, 0.91 +/- 0.21 vs 0.75 +/- 0.17, P <.05; in control subjects, 0.93 +/- 0.12 vs 0.82 +/- 0.17, P <.05). The CT data were used to determine ablation strategy and guide catheters during radiofrequency ablation., Conclusion: Multi-detector row CT provides a valuable road map for pulmonary vein anatomy prior to radiofrequency catheter ablation. Variations in number and insertion of pulmonary veins were observed in a considerable number of patients and control subjects.
