ObjectiveTo compare the disease course in patients with mild Guillain-Barré syndrome (GBS) who were treated with intravenous immunoglobulin (IVIg) or supportive care only.MethodsWe selected patients from the prospective observational International GBS Outcome Study (IGOS) who were able to walk independently at study entry (mild GBS), treated with one IVIg course or supportive care. The primary endpoint was the GBS disability score four weeks after study entry, assessed by multivariable ordinal regression analysis.ResultsOf 188 eligible patients, 148 (79%) were treated with IVIg and 40 (21%) with supportive care. The IVIg group was more disabled at baseline. IVIg treatment was not associated with lower GBS disability scores at 4 weeks (adjusted OR (aOR) 1.62, 95% CI 0.63 to 4.13). Nearly all secondary endpoints showed no benefit from IVIg, although the time to regain full muscle strength was shorter (28 vs 56 days, p=0.03) and reported pain at 26 weeks was lower (n=26/121, 22% vs n=12/30, 40%, p=0.04) in the IVIg treated patients. In the subanalysis with persistent mild GBS in the first 2 weeks, the aOR for a lower GBS disability score at 4 weeks was 2.32 (95% CI 0.76 to 7.13). At 1 year, 40% of all patients had residual symptoms.ConclusionIn patients with mild GBS, one course of IVIg did not improve the overall disease course. The certainty of this conclusion is limited by confounding factors, selection bias and wide confidence limits. Residual symptoms were often present after one year, indicating the need for better treatments in mild GBS.

ObjectiveTo define the current treatment practice of Guillain-Barré syndrome (GBS).MethodsThe study was based on prospective observational data from the first 1,300 patients included in the International GBS Outcome Study. We described the treatment practice of GBS in general, and for (1) severe forms (unable to walk independently), (2) no recovery after initial treatment, (3) treatment-related fluctuations, (4) mild forms (able to walk independently), and (5) variant forms including Miller Fisher syndrome, taking patient characteristics and hospital type into account.ResultsWe excluded 88 (7%) patients because of missing data, protocol violation, or alternative diagnosis. Patients from Bangladesh (n = 189, 15%) were described separately because 83% were not treated. IV immunoglobulin (IVIg), plasma exchange (PE), or other immunotherapy was provided in 941 (92%) of the remaining 1,023 patients, including patients with severe GBS (724/743, 97%), mild GBS (126/168, 75%), Miller Fisher syndrome (53/70, 76%), and other variants (33/40, 83%). Of 235 (32%) patients who did not improve after their initial treatment, 82 (35%) received a second immune modulatory treatment. A treatment-related fluctuation was observed in 53 (5%) of 1,023 patients, of whom 36 (68%) were re-treated with IVIg or PE.ConclusionsIn current practice, patients with mild and variant forms of GBS, or with treatment-related fluctuations and treatment failures, are frequently treated, even in absence of trial data to support this choice. The variability in treatment practice can be explained in part by the lack of evidence and guidelines for effective treatment in these situations.

ANTIPHOSPHOLIPID syndrome ,AUTOIMMUNITY ,GLYCOPROTEINS ,THROMBIN ,REACTIVITY (Chemistry) - Abstract
The diagnosis of the antiphospholipid syndrome (APS) requires both a typical clinical event plus a persistently positive test in an assay for either anticardiolipin (aCL) antibodies or a lupus anticoagulant (LA). Enzyme linked immunosorbent assays (ELISA) specific for autoantibodies against β
2 -glycoprotein I (β2 GPI) or prothrombin are also used, but none of the tests are adequately sensitive or specific. A chromogenic assay was developed that measures the effect of test antibody or plasma samples on in vitro thrombin formation. It is able to detect both LA and β2 GPI-dependent aCL antibodies and may have greater specificity for APS than currently available tests. Using this method various monoclonal antibodies (MoAbs) were examined, from mice immunized with β2 GPI, mice with a spontaneous animal model of APS, and from three humans with APS. Plasma and affinity purified antibodies from patients with APS and control groups were also examined. Thrombin inhibition was more sensitive to perturbation by MoAbs than a combination of tests for LA (P < 0·05) and at lower antibody concentrations (12·5 µg/ml versus 100 µg/ml). There was a significant correlation between inhibition of thrombin generation and the level of MoAb reactivity to β2 GPI (r = 0·90; P < 0·001) but not to CL (r = 0·06; P = 0·76). Plasma and affinity purified antibodies from patients with APS also inhibited thrombin generation, and significantly more so than patients with aPL from causes other than APS. APS patient samples showed thrombin inhibition in the presence of anti-β2 GPI or antiprothrombin antibodies. All MoAbs binding β2 GPI showed inhibition of thrombin generation, while MoAbs binding domain I of β2 GPI had more LA effect. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Autoimmune antibodies to beta(2)-glycoprotein I (beta2GPI) have been proposed to be clinically relevant because of their strong association with thrombosis, miscarriage, and thrombocytopenia. By using a homologous recombination approach, beta2GPI-null mice were generated to begin to understand the physiologic and pathologic role of this prominent plasma protein in mammals. When beta2GPI heterozygotes on a 129/Sv/C57BL/6 mixed genetic background were intercrossed, only 8.9% of the resulting 336 offspring possessed both disrupted alleles. These data suggest that beta2GPI plays a beneficial role in implantation and/or fetal development in at least some mouse strains. Although those beta2GPI-null mice that were born appeared to be relatively normal anatomically and histologically, subsequent analysis revealed that they possessed an impaired in vitro ability to generate thrombin relative to wild type mice. Thus, beta2GPI also appears to play an important role in thrombin-mediated coagulation.

- Abstract
Autoantibodies binding beta2-glycoprotein I (B2GPI) are an important finding in the antiphospholipid syndrome. While antibodies from mice or rabbits immunized with B2GPI readily bind B2GPI coated on a polystyrene microwell plate, anti-B2GPI autoantibodies only do so when using a modified microwell plate with a negatively charged surface. This study demonstrates that, for the detection of anti-B2GPI autoantibodies in an ELISA using modified plates, an antigen coating concentration threshold exists, such that minimal or no binding occurs below a certain coating concentration of antigen, even though antigen is easily demonstrable on the plate. This is consistent with the hypothesis that autoantibodies require divalent binding to B2GPI for detection, as sufficient antigen density for two protein molecules to be sufficiently close to enable divalent binding would only be expected to occur at higher coating concentrations. Several mutant forms of B2GPI developed for epitope determination experiments are shown to have decreased binding to microtitre plates compared to wild-type. If wild-type and mutants are assayed for antibody binding near the threshold a significant diminution in binding to mutants occurs that is the result of inadequate binding to the plate, but could be misinterpreted as the result of interruption of an epitope by the mutation.

- Abstract
A population of metachromatic cells with mast cell (MC) and basophil features was identified recently in the peripheral blood of patients with several allergic disorders. This study now shows that these metachromatic cells express on their surface the high-affinity IgE receptor (FcepsilonRI), CD4, and the chemokine receptors CCR3, CCR5, and CXCR4, but not the T-cell surface protein CD3 and the monocyte/macrophage surface protein CD68. This population of MCs/basophils can be maintained ex vivo for at least 2 weeks, and a comparable population of cells can be generated in vitro from nongranulated hematopoietic CD3(-)/CD4(+)/CD117(-) progenitors. Both populations of MCs/basophils are susceptible to an M-tropic strain of human immunodeficiency virus 1 (HIV-1). Finally, many patients with acquired immunodeficiency syndrome have HIV-1-infected MCs/basophils in their peripheral blood. Although it is well known that HIV-1 can infect CD4(+) T cells and monocytes, this finding is the first example of a human MC or basophil shown to be susceptible to the retrovirus.

- Abstract
We present serial neuropsychological, magnetic resonance (MR) imaging and EEG changes in a case of widespread CNS myelinopathy due to intravenous heroin overdose complicated by a period of prolonged unconsciousness. Following recovery from the acute overdose, the subject had the delayed onset of akinetic mutism with urinary incontinence. Sequential formal neuro-psychological assessments over 9 months showed evolution from severe global cerebral dysfunction to moderate disturbance of frontal lobe function. Almost complete resolution of diffuse white matter signal changes, accompanied by the development of a degree of volume loss, was evident on serial MR imaging over the same period, and generalized arrhythmic delta-range slowing on the EEG evolved int o a near normal pattern., (Copyright 2001 Harcourt Publishers Ltd.)

- Abstract
This paper examines the methodology of anti-beta(2)-glycoprotein I (beta(2)-GPI) epitope determination and provides further epitope studies using human sera containing anti-beta(2)-GPI autoantibodies. Studies in this field may be misleading as the antigen coating density using mutant forms of beta(2)-GPI may be below the threshold required for monogamous divalent binding by low affinity anti-beta(2)-GPI autoantibodies, while being easily detected by high affinity anti-beta(2)-GPI from immunized animals. The antigen density threshold effect is found in anti-beta(2)-GPI autoantibodies from humans and from monoclonal anti-beta(2)-GPI derived from mice with models of autoimmune disease. Anti-beta(2)-GPI from an autoimmune mouse and from 18/21 human sera did not bind above background levels to a domain-I-deleted mutant. In addition, single point mutations in domain I result in dramatic changes in the binding of many human sera containing anti-beta(2)-GPI. These findings support a conclusion that domain I of beta(2)-GPI contains significant epitopes for the anti-beta(2)-GPI antibodies found in the antiphospholipid syndrome., (Copyright 2000 Academic Press.)

- Abstract
Metachromatic cells in the peripheral blood of patients with asthma, allergy, or an allergic drug reaction were evaluated for their nuclear morphology, surface expression of the mast cell (MC) marker c-kit, surface expression of the basophil marker Bsp-1, and granule expression of MC proteases. Consistent with previous findings by others, Bsp-1+/metachromatic cells represented <1% of the cells in the peripheral blood of normal individuals. These cells generally contained segmented nuclei. Very little, if any, tryptase (Try), chymase (Chy), or carboxypeptidase A (CPA) was found in their granules, and very little, if any, c-kit was observed on their surfaces. The number of metachromatic cells increased in the peripheral blood of the three groups of patients. Like the basophils in normal individuals, most of these metachromatic cells contained segmented nuclei and expressed Bsp-1. However, in contrast to the basophils in normal individuals, many of the metachromatic cells in the three patient groups expressed c-kit, Try, Chy, and/or CPA. That the metachromatic cells in the blood of our patients have some features of MCs and some features of basophils suggests that human basophils and MCs are derived from a common progenitor. As assessed by the chloroacetate esterase cytochemical assay, the immunoreactive Chy in the peripheral blood of these patients is enzymatically active. Because MC proteases regulate numerous immunologic and other biologic systems, the expression of Try, Chy, and/or CPA in a peripheral blood-localized cell in an individual having asthma, allergy, or an allergic drug reaction has important clinical implications.
