Abstract
Objective: The aim of this study was to identify any potential genetic overlap between attention deficit hyperactivity disorder (ADHD) and obsessive compulsive disorder (OCD). We hypothesized that since these disorders share a sub-phenotype, they may share common risk alleles. In this manuscript, we report the overlap found between these two disorders. Methods: A meta-analysis was conducted between ADHD and OCD, and polygenic risk scores (PRS) were calculated for both disorders. In addition, a protein-protein analysis was completed in order to examine the interactions between proteins; p-values for the protein-protein interaction analysis was calculated using permutation. Conclusion: None of the single nucleotide polymorphisms (SNPs) reached genome wide significance and there was little evidence of genetic overlap between ADHD and OCD.

Abstract
We report an evaluation of a commercially available kit, the Biomérieux IgE-kit, for determination of total IgE in serum by the EIA double antibody sandwich method. Results by this procedure and PRIST (Pharmacia) show a degree of association (r) of 0·98 and a regression equation of log y = 0·79 log PRIST+log 3·31. Correlation between the IgE kit and RIST shows a degree of association of 1·00 and a regression equation of log y = 1·01 log RIST—log 1·05. Between-laboratory standard deviations are 3%, 3%, and 15% for IgE concentrations of, respectively, 83, 285, and 900 IU/ml. Similarly, intra- and inter-assay correlations were performed on 60 lyophilised serum samples tested in the four centres. No protein interference was found except for cryoprecipitates. The favourable correlation with existing procedures and the feasibility of this kit offer a new way of measuring IgE levels.

Abstract
BACKGROUND Immunonutrition has been reported to improve the immune status of perioperative cancer patients, thereby reducing complications and length of hospital stay. AIM This study aimed to assess whether immunonutrition enriched in arginine, EPA & DHA and nucleotides could impact the immune cells responses in head & neck and esophageal cancer patients treated by radiochemotherapy (RCT). METHODS A double-blind clinical trial was carried out in 28 patients randomized into two groups, receiving either an immunomodulating enteral nutrition formula (IEN, n = 13, Impact(®), Nestlé) or an isoenergetic isonitrogenous standard enteral nutrition formula (SEN, n = 15) throughout RCT (5-7 weeks). After isolation from whole blood, immune cells metabolism and functions were assessed at the beginning (Db) and at the end (De) of RCT. RESULTS Immunonutrition maintained CD4(+)/CD8(+) T-lymphocyte counts ratio and CD3 membrane expression between Db and De. Polymorphonuclear cells CD62L and CD15 densities and ROS production were increased in IEN patients. Peripheral blood mononuclear cells (PBMC) production of pro-inflammatory prostaglandin-E2 was stable in IEN patients and lower than in SEN patients at De. Genes coding for immune receptors, antioxidant enzymes and NADPH oxidase subunits were overexpressed in the PBMC of IEN vs SEN patients at De. CONCLUSION Immunonutrition can enhance immune cell responses through the modulation of their phenotypes and functions. By modulating the gene expression of immune cells, immunonutrition could make it easier for the organism to adapt to the systemic inflammation and oxidative stress induced by RCT. CLINICAL TRIAL REGISTRATION This clinical trial has been registered on ClinicalTrial.gov website: NCT00333099.

Abstract
The egcSEs comprise five genetically linked staphylococcal enterotoxins, SEG, SEI, SElM, SElN, and SElO and two pseudotoxins which constitute an operon present in up to 80% of Staphylococcus aureus isolates. A preparation containing these proteins was recently used to treat advanced lung cancer with pleural effusion. We investigated the hypothesis that egcSEs induce nitrous oxide (NO) and associated cytokine production and that these agents may be involved in tumoricidal effects against a broad panel of clinically relevant human tumor cells. Preliminary studies showed that egcSEs and SEA activated T cells (range: 11-25%) in a concentration dependent manner. Peripheral blood mononuclear cells (PBMCs) stimulated with equimolar quantities of egcSEs expressed NO synthase and generated robust levels of nitrite (range: 200-250 μM), a breakdown product of NO; this reaction was inhibited by NG-monomethyl-L-arginine (L-NMMA) (0.3 mM), an NO synthase antagonist. Cell free supernatants (CSFs) of all egcSE-stimulated PBMCs were also equally effective in inducing concentration dependent tumor cell apoptosis in a broad panel of human tumor cells. The latter effect was due in part to the generation of NO and TNF-α since it was significantly abolished by L-NMMA, anti-TNF-α antibodies, respectively, and a combination thereof. A hierarchy of tumor cell sensitivity to these CFSs was as follows: lung carcinoma > osteogenic sarcoma > melanoma > breast carcinoma >neuroblastoma. Notably, SEG induced robust activation of NO/TNFα-dependent tumor cell apoptosis comparable to the other egcSEs and SEA despite TNF-α and IFN-γ levels that were 2 and 8 fold lower, respectively, than the other egcSEs and SEA. Thus, egcSEs produced by S. aureus induce NO synthase and the increased NO formation together with TNF-α appear to contribute to egcSE-mediated apoptosis against a broad panel of human tumor cells.

Abstract
BACKGROUND Molecular allergens enable the definition of sensitization profiles in allergic patients. AIM To validate the most helpful allergens for the diagnosis of latex allergy in different clinical situations. METHODS 130 patients suspected to be allergic to latex with positive IgE against natural rubber latex (NRL) have been studied: 97 were confirmed as latex allergic (among which 55 professionally exposed to latex and 35 with a peranaesthetic anaphylactic shock) and 33 were only sensitized to latex without clinical allergy. Each serum was tested for IgE against 9 recombinant latex allergens and bromelain using Phadia ImmunoCAP 250. RESULTS rHev b 6.01, 6.02, 2 and 5 were the major allergens in the allergic population. An excellent correlation (94%) was observed between IgE against rHev b 6.01 and latex prick test positivities. IgE against rHev b 1, 3 and 5 were more frequent and their levels significantly higher in patients with peranaesthetic anaphylactic shock. Among the asymptomatic patients (29/33 allergic to pollen), NRL IgE positivity is explained by the presence of anti-rHev b 8 and/or anti-carbohydrate IgE. CONCLUSIONS rHev b 6.01 and rHev b 5 specific IgE are of major interest to confirm latex allergy diagnosis. rHev b 5 is particularly useful in case of monosensitization where clinical symptoms and latex skin prick tests may be discordant, rHev b1 and rHev b 3 are interesting to document multi-operated and peranaesthetic latex allergy. Finally, rHev b 8 is a helpful marker to highlight latex/pollen cross-reactivity which improves the specificity of the serological tests.

Abstract
Aspirin-exacerbated respiratory disease (AERD) refers to the development of bronchoconstriction in individuals with asthma following the ingestion of aspirin. AERD affects up to 20 % of adults with asthma. At present, no reliable in vitro test is available to confirm the diagnosis. The confirmation of the diagnosis of AERD therefore depends on the response to challenge testing with aspirin. The pathogenesis of AERD is linked to abnormalities in arachidonic acid metabolism. Prior to exposure to aspirin, respiratory mucosal inflammation is the result of a cell infiltration, an overproduction of leukotrienes, prostaglandins D2, 5-oxo-eicosatetraenoic acid and an underproduction of lipoxins. After aspirin ingestion, patients with AERD synthesize excessive amounts of cysteinyl leukotrienes and prostaglandin metabolites involved in bronchoconstriction. New hypotheses concerning AERD pathogenesis have been added to the initial cyclooxygenase theory. These propose that AERD may be linked to the complement system, adenosine metabolism or angiotensin converting enzyme gene and IgE receptor gene polymorphisms.

Abstract
The efficacy of anti-TNF-α therapies highlights the role of TNF-α in the pathogenesis of rheumatoid arthritis (RA). However, the mechanism of action of these agents is poorly understood at the molecular level. The aim of this study was to characterize the effects of anti-TNF-α treatment on the global gene expression profile in peripheral blood mononuclear cells (PBMCs) of responder RA patients. Changes in gene expression were determined using oligonucleotide microarrays (25,341 genes) in PBMCs obtained before and after 12 wk of treatment with either etanercept or adalimumab from responder RA patients. Two hundred fifty-one genes displayed significant changes (false discovery rate < 0.1%) in expression level (178 upregulations with mean fold change = 1.5 and 73 downregulations with mean fold change = -1.50) after 12 wk of treatment. Importantly, the expression of several genes, including those coding for the calcium binding proteins S100A12 and A8, CD14 antigen, Selectin P, or ribosomal protein L39, reported to be upregulated in RA patients, were found to be decreased after anti-TNF-α treatment. Globally, inflammation, immune response, apoptosis, protein synthesis, and mitochondrial oxido-reduction were the most affected pathways in response to anti-TNF-α treatment. The obtained gene expression signature in PBMCs provides new information to better understand the mechanisms of action of anti-TNF-α treatment in RA patients.

Abstract
Clinical difficulties in predicting systemic lupus erythematosus (SLE) renal flares are still encountered. Biological markers such as autoantibodies (aAbs) may be of major interest for clinicians in the follow-up of SLE patients. The aim of our study was to investigate the clinical utility of one of these biological markers, anti-C1q aAbs, in predicting renal flares of SLE nephritis in comparison with the 'gold standard' anti-double stranded DNA (anti-dsDNA) aAbs. Anti-C1q aAbs and anti-dsDNA aAbs were analysed through a longitudinal retrospective study of 23 SLE patients presenting with one or more renal flares. Anti-C1q and/or anti-dsDNA aAbs were found in 20 (87%) of 23 patients, of whom 16 (69%) displayed both. Thirty-three renal flares occurred during the course of the study, and anti-C1q aAbs and anti-dsDNA aAbs were positive in 25 (76%) and 24 (73%) of these flares respectively. The sensitivity of anti-C1q and/or anti-dsDNA aAbs in predicting renal flares reached 85%. The specificity of anti-C1q aAbs was 84%, of anti-dsDNA aAbs 77% and of both aAbs 97%. Positive and negative predictive values were as follows: 56% and 70% for anti-C1q aAbs, 53% and 72% for anti-dsDNA aAbs. The combination of both aAbs had the highest positive predictive value (69%), whereas absence of both aAbs was associated with the highest negative predictive value (74%). In conclusion, our results confirm that anti-C1q aAbs are present in a significant percentage of SLE patients with active renal involvement, suggesting that these aAbs could be a useful additional marker. The presence of anti-C1q and anti-dsDNA aAbs was associated with a high risk of renal flare, whereas the absence of both aAbs excluded such an event. These data confirm that systematic detection of anti-C1q and anti-dsDNA aAbs is of interest for the follow-up in SLE patients with renal involvement.

Abstract
BACKGROUND Delayed allergic skin reactions to drugs are common iatrogenic diseases mediated by activation of specific T cells in the skin. METHODS To better understand the role of T cells in these diseases, we developed a mouse model of drug allergy induced by skin sensitization to amoxicillin (amox), a penicillin antibiotic frequently involved in delayed drug allergy. RESULTS Whereas wild-type mice could not be sensitized to amox, CD4+ T-cell-deficient mice developed an amox-specific allergic skin response, mediated by IFN-gamma-producing CD8+ T cells. Amox-specific CD8+ T cells, induced in lymphoid organs at a high frequency during sensitization, were recruited in the skin upon challenge. CD8+ T cells were effectors of the allergic skin reaction to amox as in vivo treatment with depleting anti-CD8 mAbs abrogated the skin inflammatory reaction and as purified CD8+ T cells could adoptively transfer the allergic response to naive recipients. CONCLUSION CD8+ T cells mediate penicillin skin allergy.

Abstract
Drug allergic reactions presenting as maculo-papular exanthema (MPE) are mediated by drug-specific T cells. In this study, the frequency of circulating specific T cells was analyzed by interferon-gamma (IFN-gamma) enzyme-linked immunospot assay in 22 patients with an allergic MPE to amoxicillin (amox). Amox-specific circulating T cells were detected in 20/22 patients with frequencies ranging from 1 : 8000 to 1 : 30 000 circulating leucocytes. No reactivity was observed in 46 control patients, including 15 patients with immunoglobulin E-mediated allergy to amoxicillin, 11 patients with a history of drug-induced MPE but tolerant to amoxicillin and 20 healthy individuals. Furthermore, amox-specific T cells were still detectable several years after the occurrence of the allergic reaction even after strict drug avoidance. Finally, analysis of drug-specific T cells in one patient allergic to ticarcillin (a penicillin antibiotic distinct from amox) revealed the presence of IFN-gamma-producing T cells reactive to ticarcillin and several other betalactam antibiotics, suggesting that the IFN-gamma ELISPOT assay is able to detect T cell cross-reactivity against chemically related drugs. These findings confirm that drug-induced MPE is associated with the presence of specific T cells in blood and further suggest that the IFN-gamma ELISPOT is a sensitive assay which could improve the diagnosis of betalactam allergy.

Abstract
OBJECTIVE The efficacy of anti-tumour necrosis factor-alpha (TNF-alpha) therapies in rheumatoid arthritis (RA) has been mainly attributed to TNF-alpha neutralisation. Other mechanism as immune cell apoptosis, which is impaired in RA, may also be induced by anti-TNF-alpha therapies. The aim of our study was to investigate whether TNF-alpha inhibitors could induce apoptosis in vitro of the peripheral blood lymphocytes of RA patients. METHODS Peripheral blood mononuclear cells (PBMC) isolated from 24 patients with RA and 18 healthy donors were incubated with anti-TNF-alpha agents, infliximab or etanercept, in comparison with no agent and including an isotypic control, for 48 hours. Apoptosis was detected and quantified by annexin V labelling of phosphatidylserine externalization using cytofluorometric analysis and compared with PBMC production TNF-alpha in vitro. RESULTS In healthy donors, induced apoptosis was observed in 0.3% to 3.8% of lymphocytes with both therapies. In RA patients the treatment induced lymphocyte apoptosis in 17 of 24 patients with a percentage of annexin V-positive lymphocytes ranging from 0.1% to 25%. Among these 17 RA patients, a significant in vitro lymphocyte apoptosis (> 4%) was observed in 11 patients (46%) compared with healthy donors (p < 0.01). The variability of the response to anti-TNF-alpha within the RA population was not dependent on TNF-alpha synthesis or disease activity. CONCLUSION In vitro induction of lymphocyte apoptosis by anti-TNF-alpha was observed in a subgroup of RA patients. Based on these data, it would be of interest to further study the interindividual variations of sensitivity to apoptosis induced by TNF alpha inhibitors in relation to treatment efficacy or resistance observed in RA patients.

Abstract
Cellular basophil activation tests (BAT) such as histamine or sulfidoleukotriene-release tests for allergy diagnosis have been available for some time, but expression of basophil-activation markers such as CD63 and CD203c detected by flow cytometry has attracted particular attention in recent years. Not only the potential but also the possible pitfalls of flow-cytometric BAT have been stressed recently. Some authors have suggested that the technical problems are still such that BAT should only be performed in specialist laboratories. In an earlier review based on our clinical experience obtained over several years, we showed that, even using different protocols, reproducible and meaningful clinical results can be obtained. In this paper, we review the current knowledge in relation to several technical issues and show that flow-cytometric BAT already represents a major advance in the field of in vitro allergy diagnosis. We conclude that there are no serious technical justifications for depriving allergic patients of clinically indicated BAT tests, which can be performed reliably by any laboratory with the appropriate experience in allergy diagnosis and flow cytometry.

Abstract
OBJECTIVE Diabetes is clinically classified into two types: type 1 (T1D) and type 2 diabetes (T2D). Nevertheless, intermediate forms of diabetes are frequent and difficult to recognize and manage appropriately. In this study, we investigated whether patients with intermediate form of diabetes, here called unclassified diabetes (UD), have beta-cell autoimmune markers. RESEARCH DESIGN AND METHODS beta-cell autoimmune markers (beta-cell autoantibodies (aAb), peripheral blood mononuclear cells (PBMC) responsive to five islet proteins, cytokine secretion, and human leukocyte antigen (HLA)-DQB1 genotypes) were analyzed in 50 UD patients, 23 age- and HLA-matched normal control subjects, and 23 classic T2D patients. RESULTS We observed that 16 out of 50 (32%) UD patients demonstrated responsive PBMCs, as opposed to 1 out of 23 (5%) age- and HLA-matched normal control subjects, and 0 out of 23 classic T2D patients. Overall, 29 (58%) UD patients had at least one marker of beta-cell autoimmunity (beta-cell aAb and/or PBMC autoreactivity), in association with high-risk HLA genotypes DQB1*0201 and/or DQB1*0302. Moreover, the 13 (26%) UD patients who had beta-cell aAb were not the same as those with PBMC autoreactivity, except for one patient. Patients with PBMC autoreactivity were older at the onset of the disease and had a better residual beta-cell function than those with beta-cell aAb. CONCLUSIONS Our data confirm that T-cell autoimmunity can be detected in latent autoimmune diabetes in adults patients. We show an inverse correlation between humoral and cellular beta-cell autoimmunities. Possible protective cellular responses in the patients with beta-cell PBMC autoreactivity could have potential therapeutic implications.

Abstract
We have previously reported that alloreaction can lead to activation of dendritic cells through secretion of inflammatory cytokines. Here, we addressed whether alloreaction-derived cytokines may also lead to acute myelogenous leukemia (AML) blast differentiation. With this aim, supernatant (sn) harvested from major or minor histocompatibility antigen-mismatched mixed lymphocyte reaction (MLR) were used to culture French American Bristish (FAB) type M4 or M5 AML blasts. Our results showed that the secreted factors induced upregulation of CD40, CD54, and/or HLA molecules in AML blasts. Protein fractionation, blockade experiments and exogenous cytokine reconstitution demonstrated the involvement of TNF in the upregulation of CD54, CD40 and HLA-class II molecules, and of IFNgamma in the increase of HLA-class I and class II molecule expression. But, in line of its much higher levels of secretion, TNFbeta, rather than TNFalpha, was likely to play a preponderant role in AML blast differentiation. Moreover TNFbeta and IFNgamma were also likely to be involved in the AML blast differentiation-mediated by HLA-identical donor T-cell alloresponse against recipient AML blasts. In conclusion, we show herein that upon allogeneic reaction, TNFbeta secretion contributes, in concert with IFNgamma, to increase or restore surface molecules involved in AML blast interaction with T cells.

Abstract
This work aims to define the interest and the limits of free light chain (FLC) determination in serum and urine for the investigation of monoclonal gammopathies. Based on the study of nine typical cases extracted from laboratory practice, the authors demonstrate the interest of this determination for the diagnosis and the monitoring of FLC and non secretory myelomas. This test is also useful for the evaluation of response to chemotherapy and the early detection of relapses in intact immunoglobulin multiple myelomas. These results are discussed in the light of the literature with a special emphasis on AL amyloidosis and monoclonal gammapathy of undetermined significance (MGUS). Finally the authors underline some limitations leading to an overestimation of the results in certain patients together with the difficulty to interpret data when a renal damage is associated.

Abstract
OBJECTIVE Tumour necrosis factor receptor-associated periodic syndrome (TRAPS) has been associated with several mutations in the TNF receptor super family 1A (TNFRSF1A), including most cysteine substitutions. However, the nature of two substitutions, P46L and R92Q, remains a topic of discussion. The aim of this study was to assess the actual role of these two sequence variations in a series of patients with TRAPS. METHODS The main clinical data of 89 patients with TRAPS have been prospectively registered on a standard form. 84 patients or members of families with recurrent episodes of inflammatory symptoms spanning a period of more than 6 months and harbouring a TNFRSF1A mutation were studied. Clinical data have been analysed according to the nature of the mutation-P46L, R92Q or others. RESULTS P46L is often seen in patients from Maghreb and is associated with a mild phenotype. P46L appears as a polymorphism with a non-specific role in inflammation. R92Q is associated with a variable phenotype and presents as a low-penetrance mutation. Interpreting these results will require a comparison with clinical signs and genetic background.

Abstract
In septic shock, the diminished HLA-DR expression on monocytes has been proposed as a marker of immunoparalysis that correlates with an increased risk for fatal outcome. The present study was designed to determine whether some differences in protocol procedures could lead to discrepant results in HLA-DR measurement. After establishing a reliable protocol, the second objective was to illustrate the immunoparalysis in patients with septic shock. HLA-DR measurement on monocytes was determined by means of flow cytometry in 54 healthy donors and 16 patients with septic shock. We demonstrated that storage temperature, storage duration before staining and red cells lysis constitute crucial steps in HLA-DR measurement. The precision results with coefficients of variation below 5%, were quite convincing for a manual immunoassay. At 48 hours after diagnosis of septic shock, we found severely decreased percentages of monocytes expressing HLA-DR in septic patients (24 +/- 4%, mean +/- SEM) in comparison with healthy donors (90 +/- 1%), p < 0.001). Furthermore, the persistence of a low level of monocytic HLA-DR (less than 50 %) at day 9 after admittance was associated with patients who died. This study illustrates the state of immunoparalysis in patients with septic shock and supports the potential interest in measuring HLA-DR expression on monocytes. However, multicenter studies are now needed to validate this parameter. Based on our analytical results, we conclude that a critical issue in such studies will be the capacity in each center to perform standardized measurement of HLA-DR. It should be remembered that this determination requires the definition of a common analytical procedure between laboratories participating in the trial.

Abstract
BACKGROUND The flow cytometric basophil activation test by detection of CD63 expression has been developed as an alternative method for in vitro diagnosis of IgE-mediated reactions to various allergens. Despite promising initial studies, the test remains disappointing in terms of sensitivity. CD203c has recently been demonstrated as a specific activation marker of basophils that is rapidly up-regulated after allergen challenge in sensitized patients. OBJECTIVE The goal of the present study was to compare basophil activation tests by using either CD203c or CD63 in the diagnosis of immediate-type allergy to latex. METHODS Twenty-seven patients (health care workers of our institution) who developed clinical features evocative of allergy after contact with latex were included and classified into two groups. Group 1 (n = 16) comprised true allergic patients who presented with typical signs of immediate allergic reaction associated with a positive skin test (prick test). Group 2 (n = 11) consisted of patients whose clinical history was not typical and had negative skin test. Twelve healthy subjects were also studied as controls. We compared the sensitivity of two triple-staining flow cytometric protocols measuring basophil activation after latex stimulation: CD45-IgE-CD63 and CD45-IgE-CD203c. RESULTS The CD203c protocol showed a higher sensitivity than the CD63 protocol (75% vs. 50%). In comparison, latex-specific IgE sensitivity was found to be 69%. Furthermore, the magnitude of the basophil response was significantly higher with CD203c in comparison with CD63. Specificity was 100% for both protocols. CONCLUSION Due to superior gating of basophils and a higher range of activation in response to allergen, the basophil activation test is markedly improved by use of CD203c instead of CD63.

Abstract
Here, we investigated the influence of cyclosporin A (CsA) on dendritic cell (DC) generation. With this aim, human DC were propagated from monocytes in serum-free medium with granulocyte macrophage-colony stimulating factor and interleukin-4. DC were then exposed to tumor necrosis factor alpha (TNF-alpha) for maturation. Our results show that CsA does not impair commitment of monocytes into DC, as assessed by loss of CD14 and increase of CD40 and CD1a. However, TNF-alpha-induced DC maturation was affected, as CsA-treated DC expressed lower levels of human leukocyte antigen and costimulatory molecules but sustained levels of CD1a, and less DC expressed DC-lysosomal-associated-membrane-protein (LAMP) and CD83. Accordingly, CsA inhibited the allostimulatory and accessory cell functions of DC. Surprisingly, when other maturation stimuli were used, we observed that CsA significantly inhibited maturation induced by lipopolysaccharides but not by polyribocytidylic acid or CD40 ligand, as assessed by DC phenotype and functions. Therefore, our results indicate that CsA may differentially affect DC maturation.

Abstract
To assess the specificity of autoantibodies (aAbs) directed against the ribosomal P-proteins (RPPaAbs) in patients with systemic lupus erythematosus (SLE) and to investigate aAbs directed to other ribosomal proteins, 100 SLE, 100 rheumatoid arthritis (RA), 25 thyroiditis and 20 blood-donors were analyzed in a comparative study using an immunoblotting technique. Forty-eight percent of SLB sera contained aAbs directed against the ribosomal proteins of the 60 S subunit compared to 9% for RA, 5% for blood donors and 0% for thyroiditis. RPPaAbs were only found in SLE (25%) and aAbs directed to a 31 kDa and/or a 28 kDa protein of the 60 S subunit were found with a statistically higher frequency for SLE compared to RA (p < 0.0001). aAbs directed to proteins of the 40 S subunit were present in 63% of the SLE sera compared to 42% for RA, 4% for thyroiditis and 5% for blood donors. The number of positive sera was not statistically different between SLE and RA but a much more intense reactivity was observed for SLE sera. These data shows that the aAbs against the ribosomal proteins, especially the P-proteins along with the 28 and 31 kDa proteins of the 60 S subunit proteins, can be considered as useful biological markers for t he diagnosis of SLE inclinical practice.

Abstract
INTRODUCTION In patients with low-grade non-Hodgkin's lymphoma, rituximab (MabThera) produces infusion-related toxicity, including fever, rigors, and chills in greater than 50% of those treated. The majority of these reactions are grade 1 or 2. MATERIALS AND METHODS In the GELA study LNH98-5, a total of 400 elderly patients with previously untreated diffuse large B-cell lymphoma were randomized to treatment with CHOP or with rituximab plus CHOP (R-CHOP). In a detailed investigation of biological events which may be associated with adverse reactions specific to rituximab infusion, a subgroup of 55 patients (26 in the CHOP group and 29 in the R-CHOP group) were selected for measurement of several biological parameters at baseline and at 1, 4 and 8 h (H1, H4 and H8, respectively) after commencing therapy. For 27 patients, measurements included cytokine and complement levels. RESULTS Baseline demographic and disease characteristics were similar for patients in both treatment groups. Compared with the CHOP treatment group, patients in the R-CHOP group had significantly higher post-treatment changes in neutrophil, lymphocyte, and monocyte counts, LDH levels, C3a levels, and TNF-alpha levels. In the R-CHOP group, neutrophil levels increased at H4 (P<0.05), lymphocyte levels decreased at H1 (P<0.05), H4 (P<0.001) and H8 (P<0.05), monocytes levels decreased at H1 (P<0.01), LDH levels increased at H4 (P<0.05) and H8 (P<0.01), and C3a decreased at H1 (P<0.01). The most statistically significant changes were observed for TNF-alpha levels: Mean values of TNF-alpha increased more than 250% at H1 and H4 and were still increased by 170% at H8 (P<0.001 at all timepoints). Since only six of the 55 evaluated patients had severe adverse events, it was not possible to correlate severe toxicity with these biological variations. CONCLUSION This analysis demonstrates that rituximab infusion was rapidly followed by activation of complement, B-lymphocyte cytolysis, and TNF-alpha release.

Abstract
The parasite Toxoplasma gondii can infect most mammals and birds, sometimes causing severe pathology. Primary infection during pregnancy can result in abortion or fetal defects. Host immunity, particularly cellular immunity towards antigenic peptides, can control infection, but an efficient vaccine is not yet available. We have evaluated T-cell responses to a crude soluble toxoplasma antigen (ST-Ag) and to five recombinant peptide antigens of cells in whole-blood cultures from 22 pregnant women with preexisting infections and from 7 pregnant negative controls. Cells from all infected patients but from none of the controls responded specifically to ST-Ag by expressing surface CD25 on culture. Responses to the recombinant antigens showed considerable variation between individuals. rGRA1 elicited a response in 16 of the 22 samples (73%), rSAG1 in 13, rGRA7 in 9, rGRA6-CT in 4, and rGRA6-NT in only 1. Most responding cells were CD4(+). Cells from infected subjects cultured with ST-Ag all released high levels of gamma interferon (IFN-gamma) into the culture supernatant (4,343 +/- 2,536 pg/ml). Cells from 12 patients released IFN-gamma after culture with rGRA1 (130 +/- 98 pg/ml), those from 10 patients released it after culture with rSAG1 (183 +/- 128 pg/ml), and those from 4 patients released it after culture with rGRA7 (324 +/- 374 pg/ml). Intensity of IFN-gamma production in response to the latter two recombinant antigens correlated with responses to ST-Ag (r = 0.61 and 0.53, respectively; P < 0.01). Interleukin-4 was always absent from supernatants of cells stimulated with toxoplasma antigens. The heterogeneity of human responses to individual recombinant toxoplasma antigens should be considered in the design of potential vaccines.

Abstract
Procalcitonin is a 14-kDa protein encoded by the Calc-1 gene along with calcitonin and katacalcin. The function and regulation of this protein are quite different from those of the other gene products. Blood concentrations of procalcitonin are increased in systemic inflammation, especially when this is caused by bacterial infection. Studies of its behaviour in patients with bacterial sepsis have led to the proposal that it may be a useful marker of systemic bacterial infection, with greater specificity and sensitivity than acute phase proteins such as C-reactive protein.

Abstract
COBAS INTEGRA 400 is a random-access analytical system consolidating assays for clinical chemistry analytes, electrolytes, serum proteins, drugs of abuse and therapeutic drugs. Analytical performance and practicability of the instrument were evaluated in seven laboratories over a 2-year period in parallel with system development. Good within-run and total imprecision for all assays was observed with a few exceptions for specimen pools with low concentration or activity. The coefficients of variation for total imprecision were well below 3.0% for clinical chemistry analytes and electrolytes, and below 5.0% for serum proteins and therapeutic drugs. Method comparisons demonstrated a good agreement with the various systems used for comparison, with slopes varying typically from 0.94 to 1.05, and Spearman correlation coefficient generally > 0.975. Accuracy was verified by recovery of controls and certified reference materials within 90 to 110% of target values. Assay ranges were linear within +/- 5%. No carry-over on reagent or sample pipetting systems was observed. Manufacturer-specified interference limits and onboard stabilities of reagents were confirmed. A time study for calculating direct personnel times and total processing time was carried out in three laboratories under different conditions including consolidated, STAT and dedicated use. On a scenario-independent basis, the total working time was shorter on the COBAS INTEGRA 400 than on routine systems in all three laboratories. Personnel time, in particular, was significantly reduced when compared to routine instruments. In general, system practicability was judged very positively in all laboratories. Owing to its versatility, the instrument is best placed as a consolidated workstation in small- to medium-sized laboratories or as an instrument for special determinations such as serum proteins, drugs, urinalysis or emergency analyses in large laboratories.

Abstract
The occurrence of acute urticaria during treatment with drugs is a frequent event which poses two problems: 1) is the urticaria connected with the drug administration or with the underlying pathology which led to the prescription of the drug; 2) is the urticaria allergic in origin, i.e. due to specific immunity triggers, in particular IgE directed against the drug, or is the urticaria pseudo-allergic in origin, i.e. due to non-specific activation of mastocytes [1]? This question is of major importance because allergic events caused by IgE are potentially fatal while pseudo-allergic events are only rarely life-threatening. In this article we will not deal with contact urticaria where the cause is easily identifiable [2].

Abstract
The aim of our study was to compare CD3 expression on gammadelta T cells and alphabeta T cells in human patients. The antigen density of TCR and CD3 on both subsets was assessed by a quantitative method in eight patients. In parallel, we developed and validated a reliable direct tricolor staining protocol that we tested on samples from hospitalized and healthy individuals (n = 60). Our results demonstrate that human gammadelta T cells constitutively express approximately twofold more of the TCR/CD3 complex than alphabeta T cells. We suggest that this enhanced expression of the TCR/CD3 complex could contribute to the higher reactivity of gammadelta T cells compared to alphabeta T cells. These clinical laboratory results confirm the fundamental data described elsewhere. gammadelta T cells deserve further clinical investigations to understand their precise role in human immunity.

Abstract
OBJECTIVE The aim of the present study was to investigate the capacity of normal immune blood cells from non-Hodgkin's lymphoma patients to produce tumor necrosis factor (TNF) after lipopolysaccharide (LPS) stimulation and the influence of the TNF (-308) polymorphism in this production. MATERIALS AND METHODS A whole peripheral blood cell assay was utilized following LPS stimulation. At selected incubation times, supernatants were harvested for protein dosage, while mRNA was extracted and reverse-transcribed. The amount of TNF mRNA was quantified using real-time quantitative polymerase chain reaction (PCR) and genomic DNA was typed for TNF (-308) polymorphism. RESULTS Upon LPS stimulation, TNF-secreted protein was slightly but not significantly increased in lymphoma patients when compared to controls. In contrast, the relative TNF mRNA amounts were significantly higher in lymphoma patients at 30 minutes (median 27.75 vs. 16.00; Mann-Whitney U-test p < 0.05), at 4 hours (52.00 vs. 31.00; p < 0.05), and at 24 hours (19.50 vs. 9.00; p < 0.05). In addition, patients carrying the variant TNF2 allele had higher relative TNF mRNA levels than TNF1 homozygotes (p = 0.02). CONCLUSION The LPS-induced TNF mRNA levels are higher in peripheral blood cells (PBC) from lymphoma patients than from controls, while TNF protein secretion is not strikingly different. Altered regulation of TNF mRNA translation or TNF protein secretion may contribute to these observations. Taken together, an increased susceptibility for TNF gene transcription after LPS stimulation was observed in PBC (mainly in monocytes) from lymphoma patients, and especially those carrying the TNF2 allele.

Abstract
BACKGROUND YKL-40 is a 40 kDa glycoprotein secreted by chondrocytes and synoviocytes. It has been suggested that it is a surrogate marker of synovial inflammation and joint destruction in rheumatoid arthritis (RA) and osteoarthritis (OA) and related to C reactive protein (CRP) serum levels in RA. OBJECTIVE To study serum levels of YKL-40 in patients with hip OA and its relation with CRP. METHODS YKL-40 and CRP were assayed in serum samples from 45 patients (24 women, 21 men, mean age 65) with symptomatic OA of the hip and 33 healthy controls. YKL-40 was assayed by immunoassay and CRP by ultrasensitive immunonephelometry. OA severity was assessed by the measurement of joint space width with a computer analysis system of digitised hip radiographs. Statistical analysis was performed to determine correlations between serum markers and radiological joint space width. RESULTS The mean (standard error) YKL-40 level was 90.3 (8.2) ng/ml in patients with hip OA and 66.9 (8.2) ng/ml in controls (p=0.03). The mean CRP level was 2.93 (3.03) mg/l in OA and 1.40 (1.61) mg/l in controls (p=0.006). The serum levels of YKL-40 and CRP increased with age and were significantly correlated (Spearman test: r(s)=0.42, p=0.005) in patients but not in controls. Neither YKL-40 nor CRP correlated with radiographic joint space width. CONCLUSIONS Serum YKL-40 was significantly increased in patients with hip OA. The correlation between YKL-40 and CRP suggests that YKL-40 may be a marker of joint inflammation in OA. Longitudinal studies are required to assess the usefulness of YKL-40 in the monitoring of patients with hip OA.

Abstract
BACKGROUND Most patients with peritoneal carcinomatosis of digestive tract origin die within 6 months. Intraperitoneal chemohyperthermia (IPCH) associated with surgery has been reported as a possible new therapeutic approach. METHODS A prospective Phase II trial was carried out with 83 patients who had digestive tract cancer and peritoneal carcinomatosis to evaluate the tolerance and efficacy of IPCH with mitomycin C (MMC) associated with surgery. Eighty-six IPCH treatments with MMC were given as complementary therapy after surgery (peritoneal perfusate with a 10 mg/L dose of MMC; inflow temperature, 46-49 degrees C; use of a closed circuit; duration, 90 minutes). Primary tumors were mainly gastric (in 42 cases) or colorectal (in 27 cases). RESULTS Mortality and morbidity occurred in 3 of 83 cases and 8 of 83 cases, respectively. For patients with resectable tumors, the median survival time was 16 months when carcinomatosis was Stage I and II (malignant granulations less than 5 mm in greatest dimension), whereas it was 6 months when carcinomatosis was Stage III and IV (malignant granulations more than 5 mm in greatest dimension). For patients with resectable gastric cancer and Stage I and II carcinomatosis, 1-, 2-, and 3-year actuarial survival rates were 80%, 61%, and 41%, respectively, whereas the rate was 10% at 1 year for patients with bulky disease (Stage III and IV). CONCLUSIONS IPCH appears to be a promising new approach to treating patients with digestive tract cancers and peritoneal carcinomatosis with small, malignant granulations (Stage I and II).

Abstract
OBJECTIVE To characterize both phenotypic (clinical features and magnetic resonance imaging [MRI] findings) and genotypic aspects of autosomal-dominant recurrent fever, also known as tumor necrosis factor receptor (TNFR)-associated periodic syndrome (TRAPS), in a French family and to investigate the role of the mutated 55-kd tumor necrosis factor alpha (TNFalpha) receptor (TNFR1) in the pathogenesis of the disease. METHODS The coding region of TNFR1 was sequenced in 2 individuals with TRAPS (the propositus and her grandfather) and in 3 clinically unaffected relatives. Expression of soluble TNFR1 (sTNFR1) was investigated in 3 of the family members carrying a C30S mutation in TNFR1, and was compared with the levels of soluble TNFR2 (sTNFR2) by enzyme-linked immunosorbent assay. The membrane TNFR1 expression was then compared with membrane TNFR2 levels at the surface of peripheral blood mononuclear cells by flow cytometric analysis. The clinical heterogeneity in this French family was investigated by searching polymorphic variants in the TNFalpha promoter by DNA sequencing. RESULTS Both the disease course and the clinical presentation in the propositus were highly indicative of TRAPS. MRI study of the segmental inflammatory process in the limbs showed abnormal signals in the muscle and subcutaneous tissue without involvement of adjacent joints or fascia. A novel missense mutation, C30S, in the first extracellular N-terminal cysteine-rich domain (CRD1) of TNFR1 was characterized in the propositus, her affected grandfather, and her clinically unaffected father. Expression of membrane TNFR1 at the surface of monocytes and polymorphonuclear leukocytes, as well as the levels of sTNFR1 in serum when the disease was not active were not modified in the 3 individuals carrying the TNFR1 C30S mutation. In contrast, during attacks, sTNFR1 levels remained abnormally low, as compared with the levels in unrelated patients with active adult-onset systemic Still's disease. The clinical heterogeneity could not be explained by a polymorphic variant in the TNFalpha promoter. CONCLUSION TRAPS is a distinct clinical and radiologic disease entity that is responsible for recurrent fever and migratory cellulitis-like processes with localized myositis. We have identified a novel TNFR1 mutation, C30S, that is located in the CRD1 domain in a French family affected by the disease. This mutation seems to affect the level of sTNFR1, which did not increase in the propositus during inflammatory attacks.

Abstract
One of the strongest known association between human leukocyte antigen (HLA) phenotype and disease is that of ankylosing spondylitis and HLA-B27. Thus, the determination of HLA-B27 status is an useful tool in the diagnosis of ankylosing spondylitis. To date, the 2 reference methods for HLA typing (microlymphocytotoxicity and molecular biology techniques), are costly in terms of both technician time and materials, and require a great deal of experience. In total, these techniques are not well-suited for routine application in clinical immunology laboratories. Use of flow cytometry has recently been applied for HLA-B27 typing. Nevertheless, it requires an extensive validation protocol. We developed a flow cytometry technique as standardized as possible (whole blood, automated lysing system, automated photomultiplier voltage calibration, definition of thresholds stable with time) and validated our results by comparison with microlymphocytotoxicity. In total, 326 samples were analyzed. We found 99% of concordant results between the 2 techniques, and neither false positive results nor false negative results with flow cytometry could be observed. These results illustrate the reliability of the protocol. It should be remembered that reference technique remains necessary to confirm the few results (< 1%) found in "grey zone" by flow cytometry. Standardization of flow cytometry techniques, as described in this work for HLA B27, seems to be a reasonable goal for the next decade in clinical immunology laboratories.

Abstract
BACKGROUND Most patients with peritoneal carcinomatosis of digestive tract origin die within 6 months. Intraperitoneal chemohyperthermia (IPCH) associated with surgery has been reported as a possible new therapeutic approach. METHODS A prospective Phase II trial was carried out with 83 patients who had digestive tract cancer and peritoneal carcinomatosis to evaluate the tolerance and efficacy of IPCH with mitomycin C (MMC) associated with surgery. Eighty-six IPCH treatments with MMC were given as complementary therapy after surgery (peritoneal perfusate with a 10 mg/L dose of MMC; inflow temperature, 46-49 degrees C; use of a closed circuit; duration, 90 minutes). Primary tumors were mainly gastric (in 42 cases) or colorectal (in 27 cases). RESULTS Mortality and morbidity occurred in 3 of 83 cases and 8 of 83 cases, respectively. For patients with resectable tumors, the median survival time was 16 months when carcinomatosis was Stage I and II (malignant granulations less than 5 mm in greatest dimension), whereas it was 6 months when carcinomatosis was Stage III and IV (malignant granulations more than 5 mm in greatest dimension). For patients with resectable gastric cancer and Stage I and II carcinomatosis, 1-, 2-, and 3-year actuarial survival rates were 80%, 61%, and 41%, respectively, whereas the rate was 10% at 1 year for patients with bulky disease (Stage III and IV). CONCLUSIONS IPCH appears to be a promising new approach to treating patients with digestive tract cancers and peritoneal carcinomatosis with small, malignant granulations (Stage I and II).
