Abstract
BACKGROUND Significant changes in the epidemiology and natural history of rheumatoid vasculitis (RV) have occurred with the introduction of biological therapies such as TNF inhibitors (TNFi) and rituximab. PURPOSE This scoping review aims to address the key current challenges and propose updated criteria for RV. This will aid future descriptive observational studies and prospective therapeutic trials. METHODOLOGY The MEDLINE database was searched for eligible articles from inception through December 2022. Articles were selected based on language and publication date after 1998, corresponding to the approval of the first TNFi in rheumatic diseases. RESULTS Sixty articles were included in the review. The mean incidence of RV has decreased since the approval of biologic therapies in RA, from 9.1 (95% CI: 6.8-12.0) per million between 1988 and 2000 to 3.9 (95% CI: 2.3-6.2) between 2001 and 2010, probably due to significant improvement in RA severity and a decrease in smoking habits. Factors associated with an increased risk of RV include smoking at RA diagnosis, longer disease duration, severe RA, immunopositivity, and male gender (regardless of age). Homozygosity for the HLA-DRB104 shared epitope is linked to RV, while the presence of HLA-C3 is a significant predictor of vasculitis in patients without HLA-DRB104. Cutaneous (65-88%), neurologic (35-63%), and cardiac (33%) manifestations are common in RV, often associated with constitutional symptoms (70%). Histologic findings range from small vessel vasculitis to medium-sized necrotizing arteritis, but definite evidence of vasculitis is not required in the 1984 Scott and Bacon diagnostic criteria. Existing data on RV treatment are retrospective, and no formal published guidelines are currently available. CONCLUSION The understanding of RV pathogenesis has improved since its initial diagnostic criteria, with a wider range of clinical manifestations identified. However, a validated and updated criteria that incorporates these advances is currently lacking, impeding the development of descriptive observational studies and prospective therapeutic trials. PRIMARY FUNDING SOURCE This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors.

Abstract
Microvesicles (MVs) are extracellular vesicles released by several cell types upon activation or apoptosis. MVs have the potential to activate complement, which has been suggested to mediate their clearance. However, it is not clear how complement-opsonized MVs are prevented from activating circulating polymorphonuclear leukocytes (PMNs) with release of reactive oxygen species (ROS) and potential damage of endothelium and other bystander cells as consequence. We hypothesized that binding of opsonized MVs to erythrocytes (Es) attenuates MV-induced PMN activation. To test this, normal PMNs were exposed to MVs in the presence and absence of Es from allogenic healthy donors. As analyzed by flow cytometry, the presence of Es restricted the PMN binding of MVs by about 85% (p = 0.002) and mediated a 60-70% inhibition of the PMN production of the ROS H2 O2 , induced by MVs, when lipopolysaccharide was used as a primer (p = 0.002). The competitive binding of MVs to Es was partly dependent on complement, since EDTA inhibited MV binding to Es by 75%. These data suggest that Es, through competitive binding, may restrict MV-induced activation of circulating PMNs and thereby serve a role as a regulator of PMN activation.

Abstract
Autoimmune vasculitis is an endothelial inflammatory disease that results from the deposition of immune-complexes (ICs) in blood vessels. The interaction between Fcgamma receptors (FcγRs) expressed on inflammatory cells with ICs is known to cause blood vessel damage. Hence, blocking the interaction of ICs and inflammatory cells is essential to prevent the IC-mediated blood vessel damage. Thus we tested if uncoupling the interaction of FcγRs and ICs prevents endothelium damage. Herein, we demonstrate that dimeric FcγR-Igs prevented nitric oxide (NO) mediated apoptosis of human umbilical vein endothelial cells (HUVECs) in an in vitro vasculitis model. Dimeric FcγR-Igs significantly inhibited the IC-induced upregulation of inducible nitric oxide synthase (iNOS) and nitric oxide (NO) release by murine monocytic cell line. However, FcγR-Igs did not affect the exogenously added NO-induced upregulation of pro-apoptotic genes such as Bax (15 fold), Bak (35 fold), cytochrome-C (11 fold) and caspase-3 (30 fold) in HUVECs. In conclusion, these data suggest that IC-induced NO could be one of the major inflammatory mediator promoting blood vessel inflammation and endothelial cell death during IC-mediated vasculitis which can be effectively blocked by dimeric decoy FcγRs.

Elevated serum levels of macrophage migration inhibitory factor and their significant correlation with rheumatoid vasculitis disease activity. Mod Rheumatol 2011; 22:59-65. [PMID: 21607712 DOI: 10.1007/s10165-011-0466-z] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2011] [Accepted: 04/27/2011] [Indexed: 10/18/2022]
Abstract
Macrophage migration inhibitory factor (MIF) is recognized to be an important mediator in several inflammatory disorders, including rheumatoid arthritis (RA) and vasculitis. To evaluate the role of MIF in rheumatoid vasculitis (RV), we determined serum levels of MIF by enzyme-linked immunosorbent assay in RA patients with and without vasculitis and assessed their relationship to disease activity. Serum was obtained from 95 RA patients during active disease states [49 without vasculitis, 35 with extra-articular manifestations without histologically proven vasculitis, and 11 with histologically proven vasculitis] and from 22 healthy individuals. Vasculitis disease activity was assessed using the Birmingham Vasculitis Activity Score (BVAS). MIF levels were significantly higher in RA patients than in controls. Moreover, MIF levels were significantly higher in RA patients with vasculitis than in those without vasculitic complications. In all RA patients, a statistically significant positive correlation was observed between serum MIF levels and each of the following: serum levels of C-reactive protein, rheumatoid factor, and thrombomodulin; and the erythrocyte sedimentation rate. In the RV group, the elevation of MIF levels correlated with the BVAS. Our findings suggest that MIF may serve as an additional serologic inflammatory marker of disease activity in RV, and it may be implicated in the pathogenesis of RV.

Abstract
OBJECTIVE To determine levels of soluble fractalkine (sFkn) in rheumatoid arthritis (RA) patients with and without rheumatoid vasculitis (RV), and to assess the relationship of sFkn levels to disease activity. METHODS Serum was obtained from 98 RA patients (54 without vasculitis, 36 with extraarticular manifestations but without histologically proven vasculitis, and 8 with histologically proven vasculitis) and from 38 healthy individuals. Levels of sFkn were measured by enzyme-linked immunosorbent assay. Expression of Fkn and CX(3)CR1 was quantified by real-time polymerase chain reaction. Vasculitis disease activity was assessed using the Birmingham Vasculitis Activity Score and the Vasculitis Activity Index. RESULTS Serum sFkn levels were significantly higher in patients with RA than in controls and were significantly higher in RA patients with RV than in those without vasculitic complications. Statistically significant correlations were observed between serum sFkn levels in RA patients and levels of C-reactive protein, rheumatoid factor, immune complex, and complement. In the RV group, sFkn levels also correlated with disease activity. Immunohistochemical analysis indicated that Fkn levels were associated mainly with endothelial cells in vasculitic arteries. In addition, expression of CX(3)CR1 messenger RNA was significantly greater in peripheral blood mononuclear cells from patients with active RV than in those from other RA patients or controls. Notably, serum sFkn levels were significantly diminished following successful treatment and clinical improvement. CONCLUSION These findings suggest that Fkn and CX(3)CR1 play crucial roles in the pathogenesis of RV and that sFkn may serve as a serologic inflammatory marker of disease activity in RA patients with vasculitis.

Abstract
Vascular injury is considered to be a key finding in the pathogenesis of rheumatoid arthritis (RA). Manifestations are varied depending on the vessel size and the organ system involved. Vasculitis leading to symptomatic inflammatory myositis is a rare complication of RA. We describe a 62-year-old man with seropositive erosive RA of 1-year duration, who presented with severe proximal weakness and mononeuritis multiplex. His joint disease was clinically mild at the time of presentation. Creatine kinase was normal and the electromyogram did not suggest myopathy. However, muscle biopsy revealed extensive small vessel vasculitis and severe inflammatory myositis. This report emphasizes the importance of fully evaluating patients with RA who present with proximal myopathy. The myopathy in our patient was not related to active joint disease, disuse atrophy, or complication of therapy. Rheumatoid vasculitis leading to myositis is a rare and not well-recognized complication of RA for which aggressive immunosuppressive therapy is warranted.

Abstract
BACKGROUND Cutaneous manifestations are the most frequent, and often the initial feature of extra-articular involvement in patients with rheumatoid vasculitis. OBJECTIVES The purpose of the study was to evaluate the clinical and histological spectrum of cutaneous vasculitis and the associated systemic involvement in patients with rheumatoid vasculitis. METHODS Among 525 patients with rheumatoid arthritis, 20 tissue specimens with histologically proven cutaneous necrotizing vasculitis from 11 patients were investigated by studying the types and levels of affected vessels and related clinical features. RESULTS Small-vessel vasculitis identified as dermal necrotizing venulitis was found in 10 patients, clinically characterized by palpable purpura, maculopapular erythema, erythema elevatum diutinum and haemorrhagic blisters. Arteritis histologically resembling cutaneous polyarteritis nodosa, clinically characterized by subcutaneous nodules, livedo reticularis, atrophie blanche and deep ulcers was identified in four patients all with systemic complications. Coexistence of venulitis and arteritis was identified in three patients. Different cutaneous vasculitic manifestations often coexisted and recurred in the same patient. Three patients with systemic complications of mononeuritis multiplex (two of three), interstitial pulmonary fibrosis (two of three) and abdominal microaneurysms (one of three) died within 1 year of onset of the cutaneous vasculitis. Immunofluorescence demonstrated vessel wall deposition of IgM and/or complement in six of the seven patients examined. CONCLUSIONS Features of cutaneous rheumatoid vasculitis overlapping both the characteristics of cutaneous necrotizing venulitis and cutaneous polyarteritis nodosa together with coexistence of these different type of vasculitis in the same or different lesional skin account for the associated diverse cutaneous vasculitic manifestations. Although dermal venulitis (leucocytoclastic vasculitis) was the most common presentation, the presence of leucocytoclastic vasculitis in rheumatoid patients did not necessarily indicate a favourable prognosis. Associations with mononeuritis multiplex and bowel involvement had a fatal prognosis, while patients with superficial dermal venulitis without other extra-articular involvement may follow a favourable prognosis.

Abstract
The influence of HLA DRB1 alleles on B-cell homeostasis was analyzed in 164 patients with rheumatoid arthritis (RA). The percentages of CD19+ B lymphocytes determined in the peripheral circulation of 94 retrospectively recruited RA patients followed a bimodal distribution. Two frequency peaks (B-cell(low) patients and B-cell(high) patients) were separated by the population median of a B-cell frequency of 8.5% of all lymphocytes. Human leucocyte antigen genotyping revealed that the B-cell(low) patients were more frequently positive for the RA-associated HLA DRB1 shared epitope (SE) than were B-cell(high) patients. Accordingly, SE-positive patients had lower CD19 percentages in the rank-sum analysis when compared with SE-negative patients, and were markedly B lymphocytopenic when compared with a healthy control group. To confirm the differential frequencies of CD19+ B cells, absolute numbers in peripheral blood were determined prospectively in a cohort of 70 RA patients with recent onset disease. SE-positive patients were found to have lower absolute numbers of circulating CD19+ B cells. B-cell counts below the mean of the study population were associated with higher acute phase response and with increased levels of rheumatoid factor IgA. No correlation between absolute numbers of circulating B cells and radiographic progression of joint destruction was seen. The influence of immunogenetic parameters on B-cell homeostasis in RA reported here has not been described previously. The clinical relevance of B lymphocytopenia in SE-positive RA will be further investigated in longitudinal studies.

Abstract
The vascular endothelium is a common target of inflammatory joint disease. Autoimmune diseases including rheumatoid arthritis, systemic lupus erythematosus, and Sjögren's syndrome can be responsible for a spectrum of vascular disorders that encompasses vasculitis, thrombosis and/or atheroma associated with the antiphospholipid syndrome, and vascular damage caused by cryoglobulin deposition. These mechanisms can coexist, particularly in lupus patients. Joint disease is sometimes the presenting manifestation in primary vasculitis. Autoantibodies are detectable in most patients with vascular involvement and inflammatory joint disease. They are not merely markers for vascular involvement: in vitro and in vivo data suggest that some autoantibodies may contribute to the genesis of endothelial lesions, together with other factors. For instance, evidence of pathogenic effects has been found for antineutrophil cytoplasmic antibody (ANCA), most notably with antimyeloperoxidase or antiproteinase-3 specificity, in small-vessel vasculitides (Wegener's granulomatosis, Churg-Strauss syndrome, and microscopic polyangiitis); for immune complexes, particularly those containing cryoglobulins, in vasculitides secondary to CTDs; and for circulating anticoagulant and anticardiolipin antibodies, above all anti-beta2-glycoprotein I, in antiphospholipid syndrome. Antibodies to annexin V, modified lipoproteins, and endothelial cells may be of interest; their clinical relevance is unclear, however, and no standardized assays are available, so thatthese antibodies are not looked for in everyday practice. When deciding which antibody tests should be performed in a given patient, the circumstances surrounding the onset of the vasculopathy should be borne in mind. In patients with previous CTD, the tests are selected based on the diagnosis. In contrast, in a patient with no previous diagnosis, a vasculopathy can be either primary or secondary to undiagnosed CTD or to antiphospholipid syndrome: consequently, a broader array of tests is needed in this situation.

Abstract
OBJECTIVE Histological analysis of random quadriceps muscle biopsy specimens can be used to detect vasculitis in patients with rheumatoid arthritis (RA). This study aimed at determining the immunohistological features in patients with clinical suspicion of rheumatoid vasculitis, but without a transmural infiltrate or fibrinoid necrosis of the vessel wall on routine histology. METHODS Three groups of patients with RA were studied: (a) without clinical signs of vasculitis (n=6); (b) with recent onset of extra-articular features and a clinical suspicion of vasculitis but normal routine histology (n=11); and (c) with recent onset of extra-articular features and vasculitis, histologically proved either in muscle or other biopsy specimens (n=14). A control group of patients with osteoarthritis was also included (n=5). Frozen sections from quadriceps muscle biopsy specimens were analysed with monoclonal antibodies to detect CD3, CD4, CD8, CD68, ICAM-1, VCAM-1, and HLA-DR. The slides were evaluated using a semiquantitative scoring system (0-4). RESULTS The mean scores gradually increased from group 1 to 3, leading to significant differences between groups 1 and 2, but not between groups 2 and 3 for most markers (p< 0.05). Thus the pathological changes were similar for the two groups with clinical signs of vasculitis, even when the conventional histological evaluation was negative. Higher immunohistological scores were associated with perivascular infiltrates on routine histology. CONCLUSION The pathophysiological events leading to vasculitis are reflected by the changes in the quadriceps muscle biopsy specimens. The data indicate that the sensitivity of examination of muscle biopsy specimens for the diagnosis of rheumatoid vasculitis can be increased by the use of new criteria.

Abstract
OBJECTIVE To compare the ability of normal erythrocytes and erythrocytes from systemic lupus erythematosus (SLE) patients to bind immune complexes (IC), thereby inhibiting IC deposition on polymorphonuclear leukocytes (PMN) and the consequent induction of a PMN respiratory burst (RB). METHODS The binding of fluorescein isothiocyanate-labeled IC in 75% autologous serum to whole blood cells or isolated leukocytes from 17 SLE patients and 10 controls was assessed by flow cytometry. Reactive oxygen metabolite (ROM) production by PMN was measured as the intracellular oxidation of dihydrorhodamine 123, on stimulation with unlabeled IC. RESULTS Erythrocyte-mediated inhibition of IC uptake by PMN reached a mean +/- SD maximum of 68 +/- 18% in controls and 29 +/- 51% in SLE patients (P < 0.05) and, in the patients, correlated inversely with disease activity. In the presence of erythrocytes from various donors, IC binding to a standard preparation of PMN and their ROM production were inversely proportional to the number of type 1 complement receptors (CR1) per donor erythrocyte. Thus, the ROM production was higher in the presence of SLE patients' erythrocytes (125 +/- 67 CR1/erythrocyte) than with erythrocytes from controls (235 +/- 118 CR1/erythrocyte). CONCLUSION Erythrocytes from SLE patients are defective in protecting their PMN against IC deposition and induction of the RB.

Abstract
The binding of immune complexes (IC) to polymorphonuclear leukocytes (PMN) and the consequent respiratory burst (RB) were investigated in whole blood cell preparations suspended in 75% human serum, using flow cytometry. Blockade of the complement receptor (CR)1 receptor sites for C3b on whole blood cells using the monoclonal antibody (mAb) 3D9 resulted in a 1.9-fold increase in the IC-elicited PMN RB after 5 min of incubation, rising to 3.1-fold after 40 min. This enhancement was not due to increased IC deposition on PMN. Blockade of CR3 abrogated the mAb 3D9-induced rise in RB activity and inhibited the IC binding to PMN in a whole blood cell preparation, with or without mAb 3D9, by approximately 40% from 15-40 min while reducing their RB over 40 min to approximately one third. Blockade of CR1 on either erythrocytes (E) or leukocytes, before mixing the populations, revealed that the potentiation of the RB by mAb 3D9 was associated with abrogation of E-CR1 function, whereas blockade of leukocyte-CR1 had a diminishing effect. Exposure to IC at high concentrations induced release of both specific and azurophilic granule contents from PMN. The latter was CR3 dependent in that blockade of the receptor inhibited the lactoferrin release by one third during 40 min of incubation. In conclusion, CR3 plays a significant role in the IC-mediated generation of an RB and release of specific granules by PMN, while CR1 on whole blood cells, primarily E CR1, restricts the IC-elicited RB in PMN. We propose that CR1 in whole blood promotes the degradation of IC-bound iC3b to C3dg, thereby rendering the IC inaccessible for binding to CR3.

Abstract
Vasculitis, one of the clinical features shared by connective tissue diseases, should be considered when signs and symptoms are observed that may result from tissue ischaemia due to damaged vessels. The lesions seem to result from specific and non-specific immunopathogenic mechanisms targeted at the vascular endothelium. Because of the therapeutic implications it is the physician's responsibility to document its presence and the extent of organ involvement. Prompt institution of immunosuppressive drugs may be lifesaving. On the other hand there are some forms of vasculitis accompanying connective tissue disease which are entirely benign. Patients with infarctions of extremities and progressive functional disturbances of the central nervous system or internal organs because of vasculitis should be treated with high dosages of corticosteroids in combination with cytostatic drugs. Remissions are frequently obtained within three to six months of initiation of treatment and can be maintained with a less aggressive treatment regimen.

Abstract
In some patients suffering from rheumatoid arthritis (RA), vasculitis is a clear clinical manifestation, mentioned as rheumatoid vasculitis (RV). Autoantibodies directed against endothelial cells (AEA) have been implicated in the pathogenesis of this disorder, and it has been suggested in a number of studies that testing for AEA should be included in diagnosing RV. To test this hypothesis, we have evaluated the presence of AEA in sera of patients suffering from various autoimmune diseases, employing an ELISA with fixed cultured endothelial cells (EC). In all the groups of patients ELISA-positive sera were present. A significant difference in percentage of positivity was found between the RA and RV group (P < 0.05). In addition, our results indicated that not only antibodies directed against antigens on the EC membrane were detected, but also antibodies directed against intracellular components like DNA, histones and cytoskeletal components. Therefore, we also tested all these patient sera on unfixed intact EC using indirect immunofluorescence followed by FACS analysis. Whereas in the total patient population 34 out of 65 patients were AEA-positive as determined in the ELISA, only seven patients were weakly positive when examined by flow cytometry. We conclude that: (i) an ELISA on fixed EC does not specifically detect AEA. A positive test result is, however, to some extent correlated with the occurrence of vasculitis, and may therefore be helpful in diagnosing this disease; (ii) FACS analysis is a more suitable method than ELISA to measure the presence of membrane-specific AEA in patient sera; (iii) specific IgG-AEA are less common in patients suffering from autoimmune disorders than was assumed previously.

Abstract
OBJECTIVES (a) To assess plasma fibrinolytic parameters in patients with rheumatoid arthritis (RA) and to determine whether there are differences between patients with RA alone and those with RA complicated by vasculitis. (b) To determine if patients with RA respond differently to venous occlusion compared with normal subjects and to assess whether such a response differs in patients with RA alone and those with rheumatoid vasculitis. (c) To determine the extent of vascular damage in patients with rheumatoid vasculitis and if this correlates with the levels of plasma fibrinolytic parameters. METHODS Sixty three patients with RA (38 had RA only and 25 had evidence of rheumatoid vasculitis) were recruited. Plasma levels of tissue plasminogen activator antigen (t-PA Ag), plasminogen activator inhibitor (PAI) activity, and factor VIII von Willebrand factor (vWF) were measured before and 10 minutes after venous occlusion. RESULTS Patients with RA, with or without rheumatoid vasculitis, had higher baseline PAI levels than control subjects. The difference was statistically significant for patients with RA alone but was not statistically significant for patients with rheumatoid vasculitis. After venous occlusion, t-PA Ag levels increased significantly in normal subjects and patients with RA alone, but not in patients with rheumatoid vasculitis. Plasma levels of vWF were significantly higher in patients with rheumatoid vasculitis than in normal subjects and those with RA alone. In patients with RA alone, baseline vWF correlated positively with t-PA Ag levels, whereas a negative correlation was found between these two parameters in patients with rheumatoid vasculitis. A negative correlation between vWF and t-PA Ag levels after venous occlusion was also found in patients with rheumatoid vasculitis. CONCLUSIONS Patients with rheumatoid vasculitis showed evidence of vascular damage with increased levels of vWF and impaired t-PA Ag release after venous occlusion, a useful measurement of endothelial reserve to remove fibrin. This may be of pathophysiological importance in the development of vasculitis in these patients.

Abstract
Increased capillary permeability is a central feature of the severe forms of haemorrhagic fever with renal syndrome (HFRS) and occurs also, though less frequently, in nephropathia epidemica (NE), one of the milder forms of this syndrome, caused by Puumala virus. We therefore searched for antiendothelial cell antibodies (AECA) in patients with NE and in those with other presumed or serologically proven acute viral illnesses. By enzyme immunoassay, using human umbilical vein endothelial cells (HUVEC) as the substrate, IgG class AECA were detected significantly more frequently in patients with NE and with influenza A than in Red Cross blood donors. A lesser degree of reactivity could be shown with a human alveolar cell carcinoma line and with human and mouse embryonic fibroblasts. Pretreatment of HUVEC with interferon-gamma (IFN-gamma), but not with IL-1 or tumour necrosis factor-alpha (TNF-alpha), increased their ability to bind IgG of sera from patients with NE and acute febrile illnesses. We conclude that, although AECA can be demonstrated in NE, they occur also in other acute viral illnesses and, unless cytopathic by a mechanism not shared by the AECA of these other illnesses, are unlikely to be casually related to the capillary leak in HFRS.

Abstract
We investigated the ability of TNF-alpha to mediate damage of endothelial cells in the presence of neutrophils, by measuring detachment of cultured human umbilical vein endothelial cells (HUVEC). Endothelial cell detachment was increased from 5% to about 75% by the presence of 1-10 ng/ml TNF-alpha during incubation with neutrophils, whereas negligible endothelial cell lysis was observed as measured by 51Cr release. TNF-alpha was compared with the cytokines IL-1 alpha and IFN-gamma and with PMA and LPS. Both TNF-alpha and PMA appeared to be strong triggers for neutrophil-induced endothelial cell detachment, whilst reduced injury was seen after addition of IL-1 alpha and LPS. IFN-gamma did not induce endothelial cell detachment, but potentiated the effect of both TNF-alpha and IL-1 alpha. TNF-alpha-induced endothelial cell detachment was neutrophil dependent, since pre-incubation of neutrophils, but not pre-incubation of endothelial cells with TNF-alpha, caused endothelial cell detachment. Thus, TNF-alpha-induced increase in neutrophil-adhesiveness of HUVEC was found not to be essential for endothelial damage. Pre-incubation of neutrophils in suspension with TNF-alpha induced rapid activation, followed by nearly complete deactivation of neutrophils, as measured by their capacity to induce detachment of endothelial cells after removal of TNF-alpha. These results indicate that local presence of TNF-alpha might be critical in tissue or organ damage during early, neutrophil-mediated inflammatory processes, independent of enhanced adhesiveness of endothelium for neutrophils.

Abstract
In order to obtain a routine simple screening test for the detection of anti-endothelial antibodies (AEA) we developed a highly reproducible and sensitive enzyme-linked immunosorbent assay (ELISA) on fixed endothelial hybridoma cells. Detection of AEA with this type of monolayer appeared to be superior to ELISAs with monolayers of human umbilical vein endothelial cells, unfixed endothelial hybridoma cells or assays with membranes of endothelial cells. Glutaraldehyde treated endothelial hybridoma cells are most appropriate for use in ELISA procedures to detect AEA because the endothelial hybridoma cells are easy to culture, form a constant antigenic source and when plated and fixed to microtitre plates they can be stored without losing their ability to bind AEA.

Abstract
IgG anti-endothelial antibodies (AEA), as measured by ELISA or immunoblotting technique could be detected in serum samples of 56 out of 64 patients with SLE (88%) and mainly occurred in monomeric form. AEA were not cell specific, because the binding reactivity was absorbed partially by both fibroblasts and peripheral blood mononuclear cells. No correlation was found between the presence of AEA and anti-nuclear antibodies. Immunoblotting revealed reactivity of AEA against endothelial antigens ranging in size from 15 to 200 kD. AEA titres were significantly higher in patients with joint or skin abnormalities, compared with patients without these abnormalities. A significant correlation was found between nephritis in SLE and the presence of AEA reactivity against endothelial membrane antigens of 38, 41 and 150 kD. These data show that the pattern of AEA reactivity in serum of SLE patients is heterogeneous, and suggest that AEA against a limited number of antigens may be involved in the pathogenesis of nephritis in SLE.

Abstract
The role of elastase and proteinase inhibitors in polymorphonuclear leukocyte(PMN)-mediated injury to human umbilical cord venous endothelial cells (HUVEC) was investigated. Both purified human neutrophil elastase and PMN that were stimulated with serum-treated zymosan (STZ) induced detachment, but not lysis of HUVEC. PMN-, but not purified elastase-mediated detachment was enhanced by the presence of methionine, which indicates a role for reactive oxygen metabolites in PMN-mediated HUVEC detachment. Detachment of HUVEC could be inhibited by secretory leukocyte proteinase inhibitor or antileukoprotease (ALP), alpha 1-proteinase inhibitor (alpha 1-PI) and N-methoxy-succinyl-ala-ala-pro-val-chloromethyl ketone (CMK). At concentrations at which elastase-mediated detachment was maximally inhibited, ALP and CMK, but not alpha 1-PI, were also able to inhibit maximally PMN-mediated detachment. An explanation for this difference could be that the larger size of alpha 1-PI reduces the access of alpha 1-PI to the interface between the PMN and the HUVEC.

Abstract
We investigated whether a decreased complement receptor expression or function of monocytes isolated from peripheral blood of 52 patients with rheumatoid arthritis (RA) and rheumatoid vasculitis (RV) could account for the previously observed diminished degradation of immune complexes by monocytes of patients with RA and RV. On average, monocytes from all patients expressed significantly less CR1, and degraded significantly less AC3b when compared with monocytes of healthy controls. In addition, monocytes from RV patients degraded significantly less AC3b when compared with monocytes from patients with RA. The expression of both CR1 and CR3 on monocytes of RV patients was lower compared with RA patients but this difference was only significant for CR3. No differences were found between AC3b degradation and the expression of CR1 and CR3 between patients with active and inactive RA. Using linear discriminant analysis on the variables AC3b, CR1 and CR3, 94% of the patients could be classified correctly as healthy controls, RA or RV, suggesting a true multi-variate relationship between these parameters and patients groups. Our results suggest that the diminished capacity of monocytes from RA patients to degrade AC3b is due partly to a decreased expression of CR1 and CR3.
