Abstract
OBJECTIVES To analyse the safety and efficacy of the off-label use of rituximab in patients with severe, refractory systemic autoimmune diseases. METHODS In 2006, the Study Group on Autoimmune Diseases of the Spanish Society of Internal Medicine created the BIOGEAS project, a multicenter study devoted to collecting data on the use of biological agents in adult patients with systemic autoimmune diseases refractory to standard therapies (failure of at least two immunosuppressive agents). RESULTS One hundred and ninety-six patients with systemic autoimmune diseases treated with rituximab have been included in the Registry (158 women and 38 men, mean age 43 years). Systemic autoimmune diseases included systemic lupus erythematosus (107 cases), inflammatory myopathies (20 cases), ANCA-related vasculitides (19 cases), Sjögren's syndrome (15 cases) and other diseases (35 cases). A therapeutic response was evaluable in 194 cases: 99 (51%) achieved a complete response, 51 (26%) a partial response and 44 (23%) were classified as non-responders. After a mean follow-up of 27.56+/-1.32 months, 44 (29%) out of the 150 responders patients relapsed. There were 40 adverse events reported in 33 (16%) of the 196 patients. The most frequent adverse events were infections, with 24 episodes being described in 19 patients. Thirteen (7%) patients died, mainly due to disease progression (7 cases) and infection (3 cases). CONCLUSIONS Although not yet licensed for this use, rituximab is currently used to treat severe, refractory systemic autoimmune diseases, with the most favourable results being observed in Sjögren's syndrome, inflammatory myopathies, systemic lupus erythematosus and cryoglobulinemia.

Abstract
We evaluated the prevalence and clinical significance of cardiovascular risk factors in a large series of patients with primary Sjögren’s syndrome (SS), focusing on the possible association with clinical and immunological SS features, the therapies administered, and the impact on cardiovascular disease. The study cohort included 312 patients fulfilling the 2002 classification criteria for primary SS, consecutively evaluated and followed in our department between 1984 and 2009. The control group consisted of 312 age- and sex-matched patients without systemic autoimmune diseases followed during the study period in a primary care centre. In comparison with the age- and sex-matched control group, patients with primary SS showed a higher frequency of diabetes mellitus (27% versus 13%, p < 0.001) and hypertriglyceridaemia (22% versus 15%, p = 0.023), and a lower frequency of hypertension (30% versus 46%, p < 0.001) and smoking (19% versus 31%, p < 0.001). The adjusted, multivariate analysis showed that SS patients with at least three cardiovascular risk factors had a higher mean age at SS diagnosis (p < 0.001), a higher frequency of liver involvement (p = 0.01) and central nervous system involvement (p = 0.001), higher mean levels of C-reactive protein (CRP, p = 0.001), a lower percentage of circulating gamma globulins (p = 0.001), and had received corticosteroids more frequently (p = 0.003) in comparison with patients without cardiovascular risk factors. Patients who had received corticosteroids showed a higher frequency of hypertension (37% versus 25%, p = 0.032), diabetes mellitus (37% versus 21%, p = 0.002), and hypertriglyceridaemia (33% versus 15%, p < 0.001). Patients with primary SS showed a twofold higher prevalence of diabetes mellitus and a 1.5-fold higher prevalence of hypertriglyceridaemia in comparison with primary care patients. Corticosteroid use was closely associated with cardiovascular risk factors. These results suggest that cardiovascular risk factors should be taken into account in the management of patients with primary SS and show the importance of recognizing and controlling both traditional and SS-related modifiable risk factors.

Abstract
OBJECTIVES To determine the frequency, accrual, attribution and outcome of neuropsychiatric (NP) events and impact on quality of life over 3 years in a large inception cohort of patients with systemic lupus erythematosus (SLE). METHODS The study was conducted by the Systemic Lupus International Collaborating Clinics. Patients were enrolled within 15 months of SLE diagnosis. NP events were identified using the American College of Rheumatology case definitions, and decision rules were derived to determine the proportion of NP disease attributable to SLE. The outcome of NP events was recorded and patient-perceived impact determined by the SF-36. RESULTS 1206 patients (89.6% female) with a mean (+/-SD) age of 34.5+/-13.2 years were included in the study. The mean disease duration at enrollment was 5.4+/-4.2 months. Over a mean follow-up of 1.9+/-1.2 years, 486/1206 (40.3%) patients had > or =1 NP events, which were attributed to SLE in 13.0-23.6% of patients using two a priori decision rules. The frequency of individual NP events varied from 47.1% (headache) to 0% (myasthenia gravis). The outcome was significantly better for those NP events attributed to SLE, especially if they occurred within 1.5 years of the diagnosis of SLE. Patients with NP events, regardless of attribution, had significantly lower summary scores for both mental and physical health over the study. CONCLUSIONS NP events in patients with SLE are of variable frequency, most commonly present early in the disease course and adversely impact patients' quality of life over time. Events attributed to non-SLE causes are more common than those due to SLE, although the latter have a more favourable outcome.

Abstract
BACKGROUND Antimalarial drugs (AMs), chloroquine (CQ) and hydroxychloroquine (HCQ), are frequently withdrawn in patients with lupus with either severe or remitting disease. However, additional effects beyond immunomodulation have been recently described. The aim of the present work was to analyse all the published evidence of the beneficial and adverse effects of AM therapy in systemic lupus erythematosus (SLE). METHODS A systematic review of the English literature between 1982 and 2007 was conducted using the MEDLINE and EMBASE databases. Randomised controlled trials (RCTs) and observational studies were selected. Case reports were excluded except for toxicity reports. The GRADE system was used to analyse the quality of the evidence. RESULTS A total of 95 articles were included in the systematic review. High levels of evidence were found that AMs prevent lupus flares and increase long-term survival of patients with SLE; moderate evidence of protection against irreversible organ damage, thrombosis and bone mass loss. Toxicity related to AMs is infrequent, mild and usually reversible, with HCQ having a safer profile. In pregnant women, high levels of evidence were found that AMs, particularly HCQ, decrease lupus activity without harming the baby. By contrast, evidence supporting an effect on severe lupus activity, lipid levels and subclinical atherosclerosis was weak. Individual papers suggest effects in preventing the evolution from SLE-like to full-blown SLE, influencing vitamin D levels and protecting patients with lupus against cancer. CONCLUSIONS Given the broad spectrum of beneficial effects and the safety profile, HCQ should be given to most patients with SLE during the whole course of the disease, irrespective of its severity, and be continued during pregnancy.

Abstract
In recent decades, many research groups have focused on the role of viral infections in the etiopathogenesis of systemic lupus erythematosus (SLE), the so-called "viral hypothesis". The main candidates are herpes viruses such as Epstein-Barr virus (EBV) and cytomegalovirus (CMV), which have a high seroprevalence in the general population. However, a viral causal agent of SLE has not yet been discovered, although many interesting clinical findings on the complex interactions between viruses and SLE have been made. This review analyzes 88 cases of acute viral infections in adult patients with SLE and identifies situations in which viral infections influenced the diagnosis, prognosis or treatment of SLE. We also propose clinical guidelines for the management of these infections in patients with SLE.

Abstract
The complexity of the therapeutic approach in systemic lupus erythematosus (SLE) is increased by the large number of patients who do not respond to the first-line therapies and by relapses after initial clinical remission. In these patients, second-line drugs are often prescribed according to individual clinical decisions. The emergence of biological therapies has increased the therapeutic armamentarium available in these complex situations, but their use is limited by the lack of licensing. Available data on the use of rituximab in SLE rely on a large number of case reports and some observational studies. We analyzed current evidence on the therapeutic use of rituximab in adult SLE patients by a systematic review of reports included in the PubMed database between 2002 and 2007. A total of 188 SLE patients treated with rituximab were identified; 171 (91%) patients showed a significant improvement in one or more of the systemic SLE manifestations. There were 103 patients with lupus nephritis, with an overall rate of therapeutic response of renal involvement of 91%. Adverse events were reported in 44 (23%) patients; the most frequent were infections (19%). Although it is not yet possible to make definite recommendations, the global analysis of all cases reported to date support the off-label use of rituximab in severe, refractory SLE cases, whereas its use as a first-line therapy or in patients with a predominantly mild form of the disease is not advised.

Abstract
The aim of this study was to analyze the effect of exposure to antimalarial drugs at diagnosis of lupus nephritis on the outcome of the disease, especially renal failure, comorbid processes, and survival. We analyzed a cohort of 206 consecutive patients with biopsy-proven lupus nephritis. Renal biopsies were categorized according to the classification proposed by the ISN/RPS in 2003. Exposure to antimalarial drugs (chloroquine and hydroxychloroquine) was defined as the use of these drugs before the diagnosis of lupus nephritis independent of dose and duration. Fifty-six (27%) patients had received antimalarials before the diagnosis of lupus nephritis. During the follow-up, these patients had a lower frequency of creatinine values >4 mg/dL (2% vs 11%, P = 0.029) and end-stage renal failure (2% vs 11%, P = 0.044) in comparison with those never treated with antimalarials. Patients exposed to antimalarials also had a lower frequency of hypertension (32% vs 50%, P = 0.027), infections (11% vs 29%, P = 0.006), and thrombotic events (5% vs 17%, P = 0.039). Twenty patients (10%) died during the study period. Patients exposed to antimalarials had a lower mortality rate at the end of the follow-up (2% vs 13% for those not exposed to antimalarials, P = 0.029). Multivariate analysis identified thrombosis and infections as statistically significant independent variables. Kaplan-Meier plots showed a lower rate of end-stage renal failure (log rank = 0.04) in patients exposed to antimalarials. In conclusion, exposure to antimalarials before the diagnosis of lupus nephritis was negatively associated with the development of renal failure, hypertension, thrombosis and infection, and with a better survival rate at the end of the follow-up. This, together with other published data, suggests that antimalarials should be considered a mandatory therapeutic option in all patients diagnosed with systemic lupus erythematosus.

Abstract
To determine whether the clinical and immunological expression of patients with cryoglobulinaemia associated with chronic hepatitis C virus (HCV) infection varied according to HCV-RNA load, HCV genotype or human immunodeficiency virus (HIV) coinfection. We studied 340 HCV patients (188 women and 152 men, with a mean age of 49 years) consecutively diagnosed with cryoglobulinaemia between 1993 and 2003 in our hospital. HCV infection was confirmed by serum HCV-RNA determination in all patients. Two hundred and forty-eight (73%) patients had asymptomatic cryoglobulinaemia and 92 (27%) presented cryoglobulinaemic symptoms. Patients with genotype 1 had a higher mean age at diagnosis of cryoglobulinaemia (48.2 vs 40.2 yrs, P < 0.001) and a higher prevalence of cryoglobulinaemic symptoms (25%vs 10%, P = 0.02), especially of vasculitic features (19%vs 5%, P = 0.014). In comparison with monoinfected HCV patients, those with HIV coinfection had a lower mean age at diagnosis of cryoglobulinaemia (40.4 vs 52.8 years, P < 0.001), a lower prevalence of cryoglobulinaemic symptoms (15%vs 34%, P < 0.001), vasculitis (10%vs 28%, P < 0.001), associated systemic autoimmune disease (3%vs 14%, P = 0.001), rheumatoid factor (30%vs 70%, P = 0.001) and hypocomplementaemia (50%vs 78%, P = 0.01). In HCV-HIV patients, a high viral load was associated with a high frequency of symptomatic cryoglobulinaemia, especially in patients with a high viral load of the two viruses (50%vs 7%, P = 0.001) A higher frequency of cryoglobulinaemic symptoms (especially vasculitis) was found in patients with HCV monoinfection and in those carrying HCV genotype 1. In contrast, patients with HIV coinfection presented a threefold lower prevalence of vasculitis. Associated HIV infection significantly attenuated the clinical and immunological expression of cryoglobulinaemia, except in coinfected patients with high viral loads for the two viruses.

Abstract
Sjögren's syndrome (SS) is a systemic autoimmune disease that mainly affects the exocrine glands and usually presents as persistent dryness of the mouth and eyes. SS primarily affects white perimenopausal women, with an incidence of 4-5 cases per 100 000. Recent studies have analysed new therapeutic approaches, focusing mainly on the use of biological agents. B-cell targeted therapies seem to be the most promising agents in primary SS, especially rituximab, which has been used in more than 50 reported cases. Other promising B-cell targeted therapies include epratuzumab and belimumab, while T-cell targeted agents (efalizumab, abatacept, alefacept) should currently be considered as possible future options. In the near future, biological agents will play key roles in the treatment of severe involvement, broadening the therapeutic options in primary SS and offering a more optimistic point of view of the treatment of this disease, which, at present, is often considered to lack adequate specific therapy. However, the possible risks and benefits of using these agents should be carefully balanced, and a reasonable assessment of the risk of serious adverse events versus the benefits of treatment should be made. The use of biological agents targeting molecules and receptors involved in the aetiopathogenesis of primary SS opens a new era in the therapeutic management of patients with primary SS.

Abstract
OBJECTIVE To identify features present at diagnosis that were prospectively associated with adverse outcomes in a large cohort of patients with primary Sjögren's syndrome (SS). METHODS Two hundred and sixty-six patients diagnosed with primary SS in our department between 1984 and 2002 were consecutively included and followed up. Outcomes measured were vasculitis, B-cell lymphoma and death. Cox regression analysis was used to evaluate the effect of variables at diagnosis on outcomes. RESULTS Twenty-five (9%) patients developed vasculitis. Multivariate analysis identified parotid scintigraphy grades III or IV (HR 3.55, P = 0.05) and C4 levels <0.11 g/l (HR 8.26, P < 0.001) as variables predicting the development of vasculitis. Nine (3%) patients developed B-cell lymphoma. Multivariate analysis identified C3 levels <0.82 g/l (HR 7.54, P = 0.016) as a predictive factor of lymphoma development. Twenty-five (9%) patients died during follow-up. Systemic involvement (HR 4.51, P = 0.022), vasculitis (HR 4.58, P = 0.042), C4 levels <0.11 g/l (HR 5.47, P = 0.027) and cryoglobulins (HR 4.58, P = 0.013) were independently associated with death. The presence of at least two of the above-mentioned predictive factors (parotid scintigraphy, vasculitis, hypocomplementaemia and cryoglobulinaemia) was associated with a lower survival in comparison with patients with no factor (log rank and Breslow tests <0.001). CONCLUSION The main prognostic factors for an adverse outcome identified in our cohort of patients with primary SS were vasculitis, severe involvement in parotid scintigraphy, hypocomplementaemia and/or cryoglobulins at diagnosis. Patients with at least two of these factors need a closer follow-up.

Abstract
We decided to analyse the incidence and characteristics of infection in systemic lupus erythematosus (SLE) and determine the related risks factors. One-hundred and ten SLE patients and 220 controls were prospectively followed up over three years and all the infectious episodes were recorded. A case-control design was established to identify risk factors of infection. Thirty-nine SLE patients suffered at least one infection (36%) versus 53 controls (22%), RR = 1.63 (P < 0.05). The incidence of urinary infections, pneumonia and bacteraemia without known focus was significantly greater in SLE. E. coli was the chief isolated microorganism (21.3%). In the univariate analysis, nephritis, SLE activity, leucopenia, anti-dsDNA levels above 20 IU/mL, CH50 levels under 300 IU/mL, ever use of steroids, daily dose of prednisone higher than 10 mg and ever use of cyclophosphamide were significantly associated with infection. In the multivariate analysis, total serum complement levels below 300 UU/mL and a daily dose of prednisone above 20 mg during at least one month plus ever use of cyclophosphamide were found to be significant (P < 0.0001). We conclude that patients with SLE have an increased overall risk for infection and they are especially prone to develop urinary infection, pneumonia and bacteraemia without focus. Hypocomplementaemia represents an independent predictive factor for infection. It seems mandatory to closely follow up SLE patients with low complement levels and instruct them to report any suspicious sign of infection, especially in those receiving more than 20 mg/day of prednisone who have also been administered cyclophosphamide.

Abstract
OBJECTIVE To investigate the association of mannose-binding lectin (MBL)-deficient genotypes with cardiovascular disease in a large series of patients with systemic lupus erythematosus (SLE). METHODS A total of 114 patients diagnosed with SLE were included in the study. MBL polymorphisms were investigated by sequencing-based DNA typing of the promoter and exon 1 of the MBL2 gene. The genotypes 0/0, 0/XA and XA/XA were considered as MBL-low genotypes. RESULTS A higher prevalence of cardiovascular disease was observed in patients carrying MBL-low genotypes compared with those carrying MBL-high genotypes [30 vs 9%, P = 0.012, odds ratio (OR) 4.54, 95% confidence interval (CI) 1.20-16.46]. Patients with MBL-low genotypes also presented higher mean values for total cholesterol (228.6 vs 202.3 mg/dl, P = 0.017) and low-density lipoprotein (LDL) cholesterol (139.9 vs 121.9 mg/dl, P = 0.045), a higher frequency of chronic renal failure (30 vs 4%, P = 0.001), vasculitis (30 vs 11%, P = 0.043), heart valve lesions (71 vs 32%, P = 0.026), cardiac valve dysfunction (57 vs 7%, P = 0.0004) and associated APS (39 vs 12%, P = 0.005), a higher mean Systemic Lupus International Collaborating Clinics score (2.09 vs 1.26, P = 0.029) and a lower prevalence of low C4 levels (43 vs 71%, P = 0.015). Multivariate analysis of genetic, clinical and immunological variables showed that only antiphospholipid syndrome (APS) was independently associated with cardiovascular events (P = 0.001). CONCLUSION Although the prevalence of cardiovascular disease in our SLE patients carrying MBL-deficient genotypes was 3.3 times higher than in patients with non-deficient genotypes, only APS was independently associated with cardiovascular events. This suggests that the higher frequency of thrombotic events in SLE patients carrying MBL-deficient genotypes might be related to coexisting APS.

Abstract
BACKGROUND The acute respiratory distress syndrome (ARDS) is a non-cardiogenic form of pulmonary oedema characterised by severe hypoxaemia refractory to oxygen therapy, with diffuse pulmonary infiltrates on chest radiographs. It can be precipitated by various serious medical and surgical conditions, including systemic autoimmune diseases. The "catastrophic" variant of the antiphospholipid syndrome (APS) is an accelerated form of this systemic autoimmune condition which results in multiorgan failure because of multiple small vessel occlusions. OBJECTIVE To analyse the clinical and laboratory characteristics of patients with catastrophic APS who develop ARDS. METHODS Cases with ARDS were selected from the web site based international registry of patients with catastrophic APS (CAPS registry) (http://www.med.ub.es/MIMMUN/FORUM/CAPS.HTM) and their characteristics examined. RESULTS Pulmonary involvement was reported in 150 of 220 patients with catastrophic APS (68%) and 47 patients (21%) were diagnosed as having ARDS. Nineteen (40%) of these patients died. Pathological studies were undertaken in 10 patients and thrombotic microangiopathy was present in seven. There were no differences in age, sex, precipitating factors, clinical manifestations, or mortality between catastrophic APS patients with and without ARDS. CONCLUSIONS ARDS is the dominant pulmonary manifestation of catastrophic APS. Thus the existence of ARDS in the context of an APS makes it necessary to rule out the presence of the catastrophic variant of this syndrome.

Abstract
To describe the clinical and immunologic patterns of disease expression of patients with chronic hepatitis C virus (HCV) infection and positive antimitochondrial antibodies (AMA). We investigated the presence of AMA in 237 consecutive HCV patients with extrahepatic manifestations from an International Registry. AMA were detected by indirect immunofluorescence in triple rat tissue (liver, stomach and kidney), aceton-fixed criosections and FITC-conjugated rabbit anti-human immunoglobulins. We found positive AMA in 18 (8%) out of 237 HCV patients. All patients were female with a mean age at protocol inclusion of 65.8 years (ranging from 37 to 87 years). Twelve (67%) patients fulfilled classification criteria for systemic autoimmune diseases (SAD), including Sjögren's syndrome (n = 7), systemic sclerosis (n = 3) and systemic lupus erythematosus (n = 2). Fourteen (78%) of the HCV-AMA patients presented at least one of the highly suggestive characteristics of primary biliary cirrhosis (PBC): 9 (50%) had a specific M2 pattern, 6 (33%) had more than twice normal levels of alkaline phosphatase, 5 (28%) had raised IgM levels and 4 (22%) a histological pattern compatible with PBC. Five (28%) patients developed neoplasia after detection of AMA. Seven (39%) patients died, due to neoplasia (n = 4), cirrhotic complications (n = 2) and hepatopulmonary syndrome (n = 1). We describe a subset of HCV patients with positive AMA who presented a broad spectrum of clinical features, including liver, autoimmune and neoplasic manifestations. Two-thirds of these patients presented an associated SAD, mainly Sjögren's syndrome or systemic sclerosis, together with a high frequency of multiple autoantibodies and an increased prevalence of cirrhosis and neoplasia.

Abstract
The "Euro-Lupus Cohort" is composed by 1000 patients with systemic lupus erythematosus (SLE) that have been followed prospectively since 1991. These patients have been gathered by a European consortium--the "Euro-Lupus Project Group". This consortium was originated as part of the network promoted by the "European Working Party on SLE", a working group created in 1990 in order to promote research in Europe on the different problems related to this disease. The "Euro-Lupus Cohort" provides an updated information on the SLE morbidity and mortality characteristics in the present decade as well as defines several clinical and immunological prognostic factors.
