Abstract
We report one case of pregnancy-onset severe diffuse proliferative nephritis in a patient with systemic lupus erythematosus (SLE), who was successfully treated with a combination of anti-tumour necrosis factor (TNF)-alpha, plasmapheresis and high-dose intravenous gammaglobulin. No flares were observed either in clinical symptoms or in laboratory examinations during pregnancy or after delivery. Her autoantibodies except fluorescent anti-nuclear antibodies were negative. We suggest that a combination of anti-TNF-alpha, plasmapheresis and high-dose intravenous gammaglobulin may be a safe and effective therapy for pregnant patients suffering severe lupus nephritis.

Abstract
Hepatitis C virus (HCV) infection is associated with insulin resistance (IR), although mechanisms leading to IR in these patients are not completely understood. The aim of this study was to evaluate the association of interleukin 28B (IL28B) and interleukin 28 receptor alpha (IL28RA) polymorphisms with IR among human immunodeficiency virus (HIV)/HCV-coinfected patients. We carried out a cross-sectional study on 203 patients. IL28B (rs8099917) and IL28RA (rs10903035) polymorphisms were genotyped by GoldenGate(®) assay. IR was defined as homeostatic model assessment (HOMA) values ≥3.00. Univariate and multivariate generalized linear models (GLM) were used to compare HOMA values and the percentage of patients with IR according to IL28B and IL28RA genotypes. In total, 32% (n = 65/203) of the patients had IR. IL28B rs8099917 TT was not significantly associated with HOMA values and IR. In contrast, rs10903035 AA was significantly associated with high HOMA values taking into account all patients (P = 0.024), as well as the subgroups of patients with significant fibrosis (P = 0.047) and infected with HCV genotype 3 (P = 0.024). Additionally, rs10903035 AA was significantly associated with IR (HOMA ≥3.00) in all patients (adjusted odds ratio (aOR) = 2.02; P = 0.034), in patients with significant fibrosis (aOR = 2.86; P = 0.039) and HCV genotype 3 patients (aOR = 4.89; P = 0.031). In conclusions, IL28RA polymorphism (rs10903035) seems to be implicated in the glucose homeostasis because AA genotype increases the likelihood of IR, but this association was different depending on hepatic fibrosis and HCV genotype.

Abstract
Torque teno virus (TTV) and torque teno mini virus (TTMV) have been potentially related to liver diseases. The aim of the study was to quantify TTV and TTMV in human immunodeficiency virus (HIV)/hepatitis C virus (HCV)-coinfected patients to study the relationship between the TTV and TTMV viral loads and the severity of liver disease. We carried out a cross-sectional study in 245 patients coinfected with HIV and HCV (HIV/HCV-group), 114 patients monoinfected with HIV (HIV-group), and 100 healthy blood donors (Control-group). Plasma samples were tested for TTV and TTMV by quantitative real-time polymerase chain reaction (PCR). The prevalences of TTV and TTMV infections in the HIV/HCV-group and the HIV-group were significantly higher than the Control-group (p < 0.05). Furthermore, TTV and TTMV coinfections were found in 92.2 % (226/245) in the HIV/HCV-group, 84.2 % (96/114) in the HIV-group, and 63 % (63/100 %) in the Control-group (p ≤ 0.05). HIV/HCV-coinfected patients with HIV viral load ≥50 copies/mL and patients with severe activity grade had the highest viral loads of TTV and TTMV (p ≤ 0.05). HIV/HCV-coinfected patients with high TTV load (>2.78 log copies/μL) had increased odds of having advanced fibrosis or severe necroinflammatory activity grade in the liver biopsy. Moreover, HIV/HCV-coinfected patients with high TTMV load (>1.88 log copies/μL) had decreased odds of having no/minimal fibrosis and no/mild activity grade, and increased odds of having a high fibrosis progression rate. In conclusion, TTV and TTMV might play a role in the development of liver disease in immunodeficiency patients, such as the patients coinfected with HIV and HCV.

Abstract
OBJECTIVE The aim of the study was to evaluate the evolution of plasma adipokines and lipodystrophy in protease inhibitor-naıve vertically HIV-infected children on highly active antiretroviral therapy(HAART). PATIENTS AND METHODS We carried out a multicentre retrospective study of 27 children during 48 months on HAART. Every 3 months, CD4+ T-cells, CD8+ T-cells, viral load (VL), cholesterol, triglycerides, lipoproteins and adipokines were measured. Diagnoses of lipodystrophy were based on clinical examinations. RESULTS We found hypercholesterolaemia (4200 mg/dL) in 9.5, 30.4, 21.7, 14.3 and 13.3% of the subjects at months 0, 12, 24, 36 and 48, respectively, and hypertriglyceridaemia (4170 mg/dL) in 14.3, 8.3, 13,4.5 and 0% at the same time-points. During follow-up, and especially at the end of the study, we found an increase in plasma resistin levels and significant increases in total plasminogen activator inhibitor type 1, adiponectin, and leptin levels (Po0.05). We also observed slight increases in the leptin/adiponectin ratio, homeostatic model assessment, and C-peptide values during the first months of treatment followed by a moderate decrease or stabilization after 24 months on HAART.At the end of the study, 12 of the 27 children (44.4%) had lipodystrophy, 10 (37%) had lipoatrophy,and 11 (40.7%) had lipohypertrophy; and only three of the 27 children (11.1%) were diagnosed with lipoatrophy and lipohypertrophy with scores 2. CONCLUSIONS HIV-infected children showed an increase in serum adipokine levels, but this was not associated with the emergence of lipodystrophy during 48 months on HAART.

Abstract
This prospective study analyzed the relationship between several biological markers related to liver fibrosis at 3 months and 1 year post liver transplantation in 37 patients (19 with hepatitis C virus [HCV], 18 with alcoholic liver disease). Severe HCV recurrence (HCV-SR) was defined as fibrosis stage > or =F1 (METAVIR score) at 1 year and/or a value of hepatic venous pressure gradient > or=6 mmHg. We found HCV-SR patients had higher values of monocyte chemotactic protein-1 (MCP-1), soluble vascular cell adhesion molecule-1 (sVCAM-1), and hyaluronic acid (HA) than non-severe HCV recurrence patients (P<0.05). Moreover, receiver operating characteristic curve analysis showed that interferon-inducible protein 10 (IP-10) (area under the curve [AUC]: 0.74; confidence interval [CI] 95%: 0.49-0.91; P=0.043), MCP-1 (AUC: 0.78; CI 95%: 0.54-0.94; P=0.007), sVCAM-1 (AUC: 0.89; CI 95%: 0.67-0.98; P=0.005), and HA (AUC: 0.80; CI 95%: 0.55-0.94; P=0.035) have good predictive capacity for identifying severe HCV infection. The evaluation of these biomarkers may be useful in the early identification of patients in whom a more aggressive therapeutic approach could be necessary.

Abstract
Orthotopic liver transplantation (OLT) is a successful therapy for patients with end-stage liver disease, and infection remains a significant cause of morbidity and mortality for patients undergoing this procedure. To assess humoral and cellular immunity markers as potential risk factors for development of infection, 46 consecutive liver transplant recipients (hepatitis C virus cirrhosis [n=17], alcoholic liver disease [n=15], hepatocellular carcinoma [n=9], autoimmune hepatitis [n=2], and other [n=3]) performed at a single center were prospectively studied. Maintenance therapy included tacrolimus (n=37) or cyclosporine (n=9) and prednisone. During follow-up, 27 patients had at least 1 episode of infection (58.7%). Pre-OLT immunoglobulin G (IgG) hypergammaglobulinemia (relative risk [RR] 2.78; 95% confidence interval [CI], 1.17-6.60, P=0.02), pre-OLT IgA hypergammaglobulinemia (RR 2.77, CI=1.24-6.19, P=0.012), and pre-OLT C3 hypocomplementemia (RR 3.02, CI=1.21-7.55, P=0.018) were associated with an increased risk for development of infection. Monitoring of Ig and complement levels might help to identify the risk of developing infection in OLT.

Abstract
BACKGROUND Accumulating data suggest an immunopathogenic role for the complement system as a causative element in pregnancy loss (PL). Formation of pathogenic antibodies with activation of the classical pathway may have a role, but this mechanism fails to characterize the majority of cases with recurrent PL. We established the prevalence of hypocomplementemia without circulating autoantibodies in women with recurrent PL. METHODS In a retrospective case control study, 201 women with recurrent PL (two or more PL) and 30 healthy women who had normal pregnancies but no PL were studied. Serum levels of C3, C4, and factor B were determined by nephelometry. Total hemolytic activity of the complement system (CH100) was investigated by radial immunodiffusion test. RESULTS The prevalence of hypocomplementemia [low levels of C3, C4, FB or CH100 (with normal concentrations of C3, C4 and FB)] was significantly higher in women with recurrent PL (22.4%) in comparison with controls (6.6%; p = 0.019). C3, C4, FB hypocomplementemia or low CH100 were observed in 13 (6.5%), 19 (9.4%), 13 (6.5%) and 7 (3.5%) women with recurrent PL, respectively. Among patients with C3, C4, FB or CH100 hypocomplementemia, 10, 18, 12 and 5 patients had no circulating autoantibodies [antinuclear antibodies, anticardiolipin antibodies or antithyroid antibodies], respectively. In all, hypocomplementemia, in the absence of autoantibodies, was observed in 38 (18.9%) women with recurrent PL in a significantly higher frequency than controls (n = 2, p = 0.049). CONCLUSIONS Hypocomplementemia, in the absence of autoantibodies was observed in a group of women with recurrent PL which might suggest a role of the complement system in the pathogenesis of PL in these patients.

Abstract
BACKGROUND Common variable immunodeficiency (CVID) is a very heterogeneous syndrome defined by impaired immunoglobulin production. The primary defect remains unknown, but many reports describe peripheral blood T and B lymphocyte dysfunctions in a substantial proportion of CVID patients. Immunophenotypic alterations on memory B lymphocytes correlate with clinical findings. A B-cell-oriented classification principle of the patients has been proposed. METHODS AND RESULTS We investigated the expression of activation surface molecules on CD4 and CD8 T-cells from 14 patients with CVID, 6 non-CVID hypogammaglobulinemic patients with recurrent infections, 47 asymptomatic HIV-positive patients without AIDS defining conditions and 23 healthy subjects. Lymphocyte subsets were analysed by three-colour flow cytometry. Monoclonal panel: CD38-FITC/HLADR-PE/CD4 or CD8-PerCP. In CVID patients serum levels of CD4 T-cells co-expressing the activation marker HLA-DR [CD4+DR+ (34 %), CD4+CD38+DR+ (18 %)] were significantly elevated compared with controls. Significant increases in CD8+DR+ (54%), CD8+ CD38+ (43%) and CD8+CD38+DR+ (29%) T-cells were observed in comparison with healthy controls. CVID patients with splenomegaly, lower pre-infusion IgG levels (< 600 mg/dl), autoimmune or lymphoproliferative conditions demonstrated even higher levels of CD4+CD38+DR+T cells (22, 22, 21 and 21% respectively) compared with other CVID patients (13, 13, 15 and 15% respectively). CONCLUSION These findings indicate a state of ongoing T lymphocyte activation which is associated with clinical findings frequently observed in CVID.

Abstract
Immune thrombocytopenic purpura (ITP), alone or in combination with autoimmune hemolytic anemia (Evans syndrome) and/or autoimmune neutropenia, is frequent in patients with common variable immunodeficiency (CVID). A 34-year-old man with CVID had long-standing unresponsive ITP. The patient had a 9-year history of CVID on substitutive therapy with intravenous immunoglobulin (IVIG). The clinical course of CVID was complicated with refractory fistulizing inflammatory bowel disease, nodular regenerative hyperplasia of the liver, splenomegaly, severe portal hypertension, and hypercatabolism of IgG. ITP was refractory to medical therapy, including different combinations of corticosteroids, high-dose IVIG, azathioprine, and vincristine. Splenectomy was not performed because of severe portal hypertension. He received a total five doses of rituximab, a monoclonal antibody directed against CD20 antigen, at a dose of 375 mg/m(2). After an initially slow response, his platelet count increased to more than 50,000/microL by the fourth week of infusion. Therapy was well tolerated, and B lymphocytes were effectively depleted from the peripheral blood. The patient was completely tapered off glucocorticoids and maintained platelets at above 40,000/microL. The patient has not taken immunosuppressive agents for 11 months. Early treatment with rituximab might be an option for patients with CVID and ITP that do not respond to other treatments or for patients for whom a splenectomy is contraindicated.

Abstract
OBJECTIVE A descriptive study was conducted on patients with uveitis to determine the frequency of associated autoimmune systemic diseases. METHODS 64 patients with uveitis were studied. The patients were not known to have an underlying autoimmune systemic disease prior to the diagnosis of uveitis. All patients had the following immunological tests performed: serum immunoglobulins, complement components, circulating immune complexes (CIC), antinuclear antibodies (ANA), anti-neutrophil cytoplasmic antibodies (ANCA), anti-cardiolipin antibodies (ACA) and major histocompatibilty complex antigens. RESULTS A relationship with a sub-clinical autoimmune systemic disorder could be presumed in eleven cases (17.2%). This was defined by positive autoantibodies (ANA, ANCA or ACA) in the presence of complement consumption, hyper-gammaglobulinemia or increased CIC without clinical criteria of a defined autoimmune disease. A definite association with systemic autoimmune disease was defined in four patients (6.25%). The observed autoimmune systemic diseases were Sjögren's syndrome (n=2, 3.13%), anti-phospholipid syndrome associated with lupus-like disease (n=1, 1.6%), and systemic vasculitis (n=1, 1.6%). Lupus-like disease (n=4, 6.25%) was also observed. CONCLUSION In a significant proportion of patients with uveitis an autoimmune systemic disorder may be present and should be looked for.

Abstract
OBJECTIVES Clinical and immunological features of patients with clinical manifestations of the antiphospholipid syndrome (APS) with anti-beta2-glycoprotein-I antibodies (anti-beta2-GP-I) but without anticardiolipin antibodies (aCL) or any other autoimmune condition are not well documented. We sought to determine the clinical significance of positive anti-beta2-GP-I with negative aCL. METHODS From July 2002 through July 2003, 1,179 serum samples obtained in our hospital from the Community of Madrid were tested for anti-beta2-GP-I and aCL by enzyme-linked immunosorbent assay. Clinical records of patients with discordant anti-beta2-GP-I and aCL were retrospectively analysed. RESULTS A total of 56 patients with discordant anti-beta2-GP-I and aCL were identified. By logistic regression analysis, after adjusting for age, sex and risk factors of thrombosis, the risk for developing APS criteria associated with anti-beta2-GP-I was significant [odds ratio 3.88; 95% confidence interval (CI): 1.05-14.27; p = 0.04). 15 out of 56 patients (26.8%) had positive anti-beta2-GP-I and negative aCL. 5 out of 15 anti-beta2-GP-I-positive patients had clinical APS without serological nor clinical evidence of any autoimmune disease. CONCLUSION Determination of anti-beta2-GP-I should be considered in individual cases with clinical manifestations of primary APS and repeated negative results on conventional antiphospholipid antibody test.
