Abstract
OBJECTIVES To describe the clinical and immunologic characteristics of a large series of patients with systemic autoimmune diseases (SAD) associated with chronic hepatitis C virus (HCV) infection. METHODS We analysed 180 patients diagnosed with SAD and chronic HCV infection seen consecutively at our centres during the last 10 years. The clinical and immunological patterns of disease expression were compared with 180 SAD-matched patients without chronic HCV infection. RESULTS A total of 180 HCV patients fulfilled the classification criteria for the following SAD: Sjogren's syndrome (n = 77), systemic lupus erythematosus (n = 43), rheumatoid arthritis (n = 14), antiphospholipid syndrome (n = 14), polyarteritis nodosa (n = 8) and other SAD (n = 24). One hundred and thirty (72%) patients were female and 50 (28%) male, with a mean age at SAD diagnosis of 50 years. The main immunologic features were antinuclear antibodies in 69% of patients, cryoglobulinaemia in 62%, hypocomplementaemia in 56% and rheumatoid factor (RF) in 56%. Compared with the SAD-matched HCV-negative group, SAD-HCV patients presented a lower prevalence of females (P = 0.016), an older age at SAD diagnosis (P = 0.039) and a higher prevalence of vasculitis (P < 0.001) and neoplasia (P < 0.001). Immunologically, SAD-HCV patients presented a lower prevalence of antinuclear (P = 0.036), anti-extractable nuclear antigen (P = 0.038) and anti-DNA (P = 0.005) antibodies, and a higher frequency of RF (P = 0.003), hypocomplementaemia (P < 0.001) and cryoglobulins (P < 0.001). CONCLUSIONS In comparison with an SAD-matched HCV-negative population, SAD-HCV patients were older and more likely to be male, with a higher frequency of vasculitis, cryoglobulinaemia and neoplasia. This complex pattern of disease expression is generated by a chronic viral infection that induces both liver and autoimmune disease.

Abstract
OBJECTIVE To evaluate health-related quality of life (HR-QoL) in patients with primary SS patients using the SF-36 questionnaire and to analyse the association between the main clinical features and the SF-36 scales. METHODS We studied 110 patients (105 women and 5 men, mean age of 56 years) with primary SS seen consecutively in the outpatient clinic of our Department. We used the population-based reference values for the Spanish version of the SF-36 health survey as control values for a healthy population. RESULTS Comparison between patients with primary SS and the control population showed lower scores in all SF-36 scales (p < 0.001). Analysis of the SF-36 scales by gender showed a significant correlation between age and the values for physical functioning (p = 0.013) and bodily pain (p = 0.016) scores. No significant differences in SF-36 scores were found when comparing patients according to the presence or absence of sicca features. Women with vaginal dryness had lower scores for social functioning (61.9 vs. 74.4) and general health (37.2 vs. 44.7) than those without, although the differences were not statistically significant (p > 0.05). Patients with extraglandular involvement had lower scores for the vitality scale (40.8 vs. 54.5 p = 0.007), social functioning (67.0 vs. 79.8, p = 0.010), bodily pain (49.5 vs. 62.5, p = 0.018) and general health (38.6 vs. 49.4 p = 0.001) than those without. CONCLUSION Patients with primary SS had clearly lower HR-QoL scores than the healthy population; with significantly lower scores in all SF-36 scales and in both summary measures. We identified several epidemiological and clinical SS features related to these lower SF-36 scores. Age at protocol correlated with physical functioning and bodily pain. Vaginal dryness was the sicca feature that most affected the HR-QoL of female SS patients, and a poor HR-QoL was also observed in those patients with a systemic expression of the disease, with pulmonary involvement being the extraglandular manifestation that most contributed to a poor HR-QoL. Our results highlight the importance of earlier diagnostic and therapeutic management of patients with primary SS, which, together with a close follow-up, may contribute to a significant improvement in their HR-QoL.

Abstract
The objective of the study was to analyse the prevalence and clinical significance of hypocomplementemia in a large series of patients diagnosed either with systemic lupus erythematosus (SLE) or with primary antiphospholipid syndrome (APS) and its association with the main clinical, hematological and immunological features of these diseases. Between 1992 and 2003, complement determinations (C3 and C4 levels, CH50 activity) were performed in 597 consecutive patients diagnosed with SLE (530 women and 67 men, mean age 32.6 years) and 70 with primary APS (57 women and 13 men, mean age 38.7) visited in our department. Complement determinations are routinely made at the first visit of patients and yearly during the follow-up. SLE and primary APS were diagnosed according to current classification criteria. Hypocomplementemia was detected in 371 (62%) of SLE patients. Compared with patients with normal complement values, those with hypocomplementemia showed a higher prevalence of female gender (P < 0.001), fever (P = 0.021), nephropathy (P < 0.001), cutaneous vasculitis (P = 0.023), positive anti-dsDNA antibodies (P = 0.012) and cryoglobulinemia (P < 0.001). In addition, patients with hypocomplementemia showed a higher prevalence of APS-related features such as hemolytic anemia (P = 0.001) and antiphospholipid antibodies (P < 0.001). Hypocomplementemia was prospectively related to accumulated hospitalization in SLE patients but not with the accumulated number of lupus flares or with the survival after follow-up of five years. In contrast, 33 (47%) patients with primary APS presented low complement values, which were associated with a higher prevalence of livedo reticularis (P = 0.022), thrombocytopenia (P = 0.004), lupus anticoagulant (P = 0.013), positive IgM-aCL (P = 0.039), positive ANA (P = 0.002) and anti-dsDNA (P = 0.046). The diagnostic value of hypocomplementemia in patients with SLE is based on the association with disease activity, immune-complex mediated manifestations (glomerulonephritis, cryoglobulinemia) and APS-related features (livedo reticularis, hemolytic anemia and aPL). Hypocomplementemia was found in nearly half of patients with primary APS, and was associated with some APS features (livedo reticularis, thrombocytopenia, aPL) but also with SLE-related immunological markers (ANA and anti-dsDNA), identifying a subset of patients with primary APS with a higher risk of evolving to SLE. These results clearly support the routine determination of complement factors in the clinical follow-up of patients with SLE and primary APS.

Abstract
OBJECTIVE To describe the characteristics of patients with catastrophic antiphospholipid syndrome (APS) included in the International Registry of patients with this condition (CAPS registry) and to analyse the value of the recently proposed preliminary criteria for the classification of catastrophic APS. METHODS A review of the first 220 patients included in the website based CAPS registry was undertaken and the preliminary criteria for their classification were tested; 175 unselected patients with systemic lupus erythematosus or APS, or both, acted as controls. RESULTS The mean age of the patients was 38 (14) years (range 7 to 74), with a female preponderance (F/M, 153/67). The main clinical manifestations included renal involvement in 154 (70%), pulmonary in 146 (66%), cerebral in 133 (60%), cardiac in 115 (52%), and cutaneous in 104 (47%); 114 patients (52%) recovered after the catastrophic APS event (mortality 48%). Patients who received the combination of anticoagulation plus steroids plus plasma exchange or intravenous immunoglobulins had the best survival rate (63%, p = 0.09). Sufficient data could be analysed for application of the classification criteria in 176 patients. According to the preliminary criteria, 89 patients (51%) could be classified as having "definite" and 70 (40%) as having "probable" catastrophic APS, thus given a sensitivity of 90.3% with a specificity of 99.4%. Positive and negative predictive values were 99.4% and 91.1%, respectively. CONCLUSIONS The preliminary criteria for the classification of catastrophic APS and the CAPS registry are useful tools for epidemiological studies.

Abstract
BASIS A significant proportion of our patients has described to have problems from tolerance to Dolquine, a new presentation of hydroxychloroquine recently marketed in Spain, compared to Plaquenil. The objective was to know the tolerability and the adverse effects of this new presentation. PATIENTS AND METHOD A cross-sectional multicenter study on 133 patients treated with Dolquine was conducted. RESULTS Of the 133 patients (87% women; average age [AA]: 32.9 [15.4] years) who received Dolquine during an average period of 6.7 (1.4) months, 32 patients (24%) described to have more problems with this drug in comparison with other antimalarial. The adverse effects experienced were: bitter taste (62.4%), difficulty in swallowing the tablet (13.5%), dyspepsia (9.8%), nausea (7.5%), vomiting (1.5%), pruritus (1.5%), diarrhea (0.7%), and instability feeling (0.7%). The presence of gastrointestinal adverse effects was not related to the consumption of gastroerosive drugs, gastric protectors, or a high number of drugs. The attrition rate was 9.8%. Conclusions. Dolquine induces lower tolerance and more gastrointestinal adverse effects than Plaquenil, pointing out its bitter taste and the difficulty in swallowing it. Despite this higher intolerance there was not an increase in the attition rate from the antimalarial treatment in comparison to other series.

Abstract
Multiple cartilaginous exostosis was diagnosed in a six-month-old Golden Retriever cross-bred male with a history of forelimb lameness and isolated, but very painful, acute episodes. Physical examination revealed a right forelimb lameness with a firm, painful palpable mass on the cranial aspect of the forearm. The radiological examination showed the presence of bony masses at the humerus and radius as well as several masses in the ribs and spinous processes of the thoracic vertebrae. Based on the history and radiographic findings, multiple cartilaginous exostosis was diagnosed. Treatment with non-steroidal anti-inflammatory drugs was commenced for two weeks without any effect. Due to the lack of a response to the treatment as well as to the progressive physical deterioration of the animal, the owners requested euthanasia of the dog. Histology of the different exostoses demonstrated the presence of a hyaline cartilage cup surrounding a central area, formed mainly by bone and cartilage trabecullae. Signs of malignancy were not observed. Back-scattered scanning electron microscopy (BEI-SEM) study revealed well ordered and progressively calcified cartilage trabecullae present underneath the non-calcified cartilage cap. At a greater depth, those cartilage trabecullae became osteochondral trabecullae, and the innermost were formed exclusively by woven and lamellar bone. The histological and back-scattered electron scanning microscopy results conclude that it was a well-arranged normal endochondral ossification process that followed a centripetal pattern inside the bony mass, confirming the diagnoses of multiple cartilaginous exostoses.

Abstract
OBJECTIVE To analyse the clinical and radiological characteristics of patients with dementia associated with the antiphospholipid syndrome (APS). METHODS Twenty-five patients were identified by a computer-assisted (MEDLINE, National Library of Medicine, Bethesda, MD) search of the literature to locate all cases of dementia associated with APS published in English, Spanish and French from 1983 to 2003. Additionally, we included five patients from our clinics. RESULTS There were 21 (70%) females and 9 (30%) males. The mean age of patients was 49+/-15 yr (range 16-79 yr). Fourteen (47%) of the patients suffered from primary APS, 9 (30%) had systemic lupus erythematosus and 7 (23%) had 'lupus-like' syndrome. Ten (33%) patients had Sneddon's syndrome and 2 (7%) had cerebral lesions described as Binswanger's disease. Other APS-related manifestations included thrombocytopenia in 12 (40%) patients, cerebrovascular accidents in 11 (37%), heart valve lesions in 8 (27%), deep vein thrombosis in 7 (28%), migraine in 7 (23%), seizures in 4 (13%); five of the 21 (24%) female patients had nine spontaneous abortions. Lupus anticoagulant was present in 21/29 (72%) patients and anticardiolipin antibodies were present in 24/29 (83%) patients. Cortical infarcts were found in 19 (63%) patients, subcortical infarcts in 9 (30%), basal ganglia infarcts in 7 (23%) and signs of cerebral atrophy in 11 (37%). Anticoagulation was used in 14/25 (56%) patients, steroids in 12/25 (48%), aspirin in 6/25 (24%) and dypiridamole in 5/25 (20%). CONCLUSIONS Dementia is an unusual manifestation of APS but one which has a high disability impact in a patient's daily life. In order to prevent these consequences, an echocardiographic and cerebral CT or MRI evaluation are recommended in all patients with APS. Furthermore, ruling out APS should be recommended in the clinical approach to dementia, especially in young patients.

Abstract
OBJECTIVE To analyse the prevalence and clinical significance of hypocomplementaemia in a large series of patients with primary Sjogren's syndrome (SS), focusing on the association of low complement levels with clinical manifestations, immunological features, lymphoproliferative disorders and mortality. METHODS Complement determinations (C3 and C4 levels, CH50 activity) were made in 336 consecutive patients with primary SS (313 women and 23 men, mean age 58.5 yr). We also analysed complement levels in 46 patients with SS associated with hepatitis C virus (HCV) infection and 184 with HCV-related cryoglobulinaemia as control groups. RESULTS Hypocomplementaemia was detected in 81 (24%) of patients with primary SS, low CH50 being detected in 51 (15%), low C3 values in 42 (12%) and low C4 values in 39 (12%). In the multivariate analysis, patients with low C4 levels showed a higher prevalence of peripheral neuropathy, cutaneous vasculitis, RF, cryoglobulins and lymphoma compared with those with normal C4 levels. The analysis of the 218 SS patients followed prospectively since 1994 showed a lower probability of survival in patients with hypocomplementaemia (with low C3, C4 or CH50 levels) at protocol entry. SS-HCV patients presented a higher frequency of hypocomplementaemia than patients with primary SS (76 vs 24%, P<0.001); nine (20%) of these patients had persistent, unquantifiable complement levels. CONCLUSION Hypocomplementaemia is closely associated with systemic expression and adverse outcomes (lymphoma development and death) in patients with primary SS. Our results support the inclusion of complement determination at diagnosis as a predictor of the outcome of patients with primary SS and its routine determination in the clinical follow-up.

Abstract
Susac's syndrome is a microangiopathic disorder of unknown pathogenesis presenting with encephalopathy, hearing loss and branch retinal artery occlusions. The term 'catastrophic' antiphospholipid syndrome (APS) is used to define a subset of the APS characterized by thrombotic microangiopathy with clinical evidence of three or more organ involvement developed in a short period of time. We describe a patient with typical features of Susac's syndrome, that appeared in less than a week, in whom aPL were detected, thus fulfilling criteria for 'probable' catastrophic APS.

Abstract
OBJECTIVE To describe and analyse the clinical characteristics of 100 patients with antiphospholipid syndrome (APS) associated with infections. METHODS Patients were identified by a computer assisted search (Medline) of published reports to locate all cases of APS published in English, Spanish, and French from 1983 to 2003. The bilateral Fisher exact test was used for statistics. RESULTS 59 female and 41 male patients were identified (mean (SD) age, 32 (18) years (range 1 to 78)): 68 had primary APS, 27 had systemic lupus erythematosus, two had "lupus-like" syndrome, two had inflammatory bowel disease, and one had rheumatoid arthritis. APS presented as a catastrophic syndrome in 40% of cases. The main clinical manifestations of APS included: pulmonary involvement (39%), skin involvement (36%), and renal involvement (35%; nine with renal thrombotic microangiopathy, RTMA). The main associated infections and agents included skin infection (18%), HIV (17%), pneumonia (14%), hepatitis C (13%), and urinary tract infection (10%). Anticoagulation was used in 74%, steroids in 53%, intravenous immunoglobulins in 20%, cyclophosphamide in 12%, plasma exchange in 12%, and dialysis in 9.6%. Twenty three patients died following infections and thrombotic episodes (16 with catastrophic APS). Patients given steroids had a better prognosis (p = 0.024). The presence of RTMA and requirement for dialysis carried a worse prognosis (p = 0.001 and p = 0.035, respectively). CONCLUSIONS Various different infections can be associated with thrombotic events in patients with APS, including the potentially lethal subset termed catastrophic APS. Aggressive treatment with anticoagulation, steroids, and appropriate antibiotic cover is necessary to improve the prognosis.

Abstract
Sicca features are the central clinical manifestations of Sjögren's syndrome (SS), but recent studies have confirmed that primary SS has a systemic expression, including extraglandular manifestations. Patients with a predominantly extraepithelial expression should be managed differently from patients with predominantly periepithelial or sicca limited disease. In coming years treatment will be based on muscarinic agonists for sicca features and immunosuppressive/biological agents for extraglandular features.

Abstract
Two-hundred ninety five patients with the antiphospholipid syndrome (APS) were studied for the presence of antibodies against six anti-beta2GPI-related peptides Abs. The prevalence of a wide spectrum of clinical and laboratory parameters of APS was evaluated in all patients, and correlated with the presence of each anti-beta2GPI peptide antibody. The rates of the various antipeptides Abs ranged from 18.0 to 63.7%. Altogether, 87.1% of the patients had antibody reactivity against at least one of the six beta2GPI-related peptides. A high degree of simultaneous reactivity against several beta2GPI-peptides was found. Positive and negative correlations were found between several antipeptides Abs and the rates of thrombosis and fetal loss. Our results point to a heterogeneous activity of antiphospholipid Abs in APS patients, directed, often concurrently, against various epitopes of the beta2GPI molecule. Evaluation of APS patients for the presence of specific antipeptides Abs may be of a value in predicting the risk for future thrombotic and obstetrical complication, as well as for specific therapeutic purposes.

Abstract
OBJECTIVE To analyse the clinical and laboratory features of patients with thrombotic microangiopathic haemolytic anaemia (TMHA) associated with antiphospholipid antibodies (aPL). METHODS A computer assisted (PubMed) search of the literature was performed to identify all cases of TMHA associated with aPL from 1983 to December 2002. RESULTS 46 patients (36 female) with a mean (SD) age at presentation of TMHA of 34 (15) years were reviewed. Twenty eight (61%) patients had primary antiphospholipid syndrome (APS). TMHA was the first clinical manifestation of APS in 26 (57%) patients. The clinical presentations were haemolytic-uraemic syndrome (26%), catastrophic APS (23%), acute renal failure (15%), malignant hypertension (13%), thrombotic thrombocytopenic purpura (13%), and HELLP (haemolysis, elevated liver enzymes, and low platelet count in association with eclampsia) syndrome (4%). Lupus anticoagulant was detected in 86% of the episodes of TMHA, and positive anticardiolipin antibodies titres in 89%. Steroids were the most common treatment (69% of episodes), followed by plasma exchange (PE) (62%), anticoagulant or antithrombotic agents (48%), immunosuppressive agents (29%), and immunoglobulins (12%). Recovery occurred in only 10/29 (34%) episodes treated with steroids, and in 19/27 (70%) episodes treated with PE. Death occurred in 10/46 (22%) patients. CONCLUSIONS The results emphasise the need for systematic screening for aPL in all patients with clinical and laboratory features of TMHA. The existence of TMHA in association with an APS forces one to rule out the presence of the catastrophic variant of this syndrome. PE is indicated as a first line of treatment for all patients with TMHA associated with aPL.

Abstract
The immune system undergoes continuous morphologic and functional changes throughout the years, and it is now believed that the immune response has its peak function in puberty and gradually decreases with age (immunosenescence). Recent studies in healthy octogenarian patients suggest that the immune system, instead of suffering a generalized deterioration, undergoes a remodelling/readjustment of its major functions. Increase in two contrasting phenomena coexist in immunosenescence: on the one hand, a decrease in the capacity of the immune response and, on the other hand autoantibody production. The possible consequences of this progressive 'ageing' of the immune system are the increase in autoimmune phenomena, incidence of neoplasia and predisposition to infections. The study of autoimmune manifestations in elderly populations should be considered a priority for future medical research because of increasing life expectancy, especially in developed countries. This review analyses the main immune disorders associated with immunosenescence, the prevalence and clinical significance of autoantibodies in the elderly and the clinical expression of the main autoimmune diseases in older patients.

Abstract
Although Addison disease and hypoadrenalism are rare in patients with systemic lupus erythematosus (SLE), early reports of the association suggested the presence of antiphospholipid antibodies (aPL) in these patients. Data from literature reveal that adrenal failure was present in between 10 and 26% of patients with catastrophic APS and that one-third of patients presented with adrenal involvement during the course of catastrophic APS. Adrenal involvement may be the first clinical manifestation of this syndrome, whereas a few patients may have a history of Addison's disease in the past. The pathological mechanisms involved in the production of adrenal insufficiency in APS are still not clearly understood, but the hypercoagulable state in these patients supports the concept that adrenal haemorrhagic infarction may possibly be related to adrenal vein thrombosis. In the present article,we review the pathogenic mechanisms and main clinical, laboratory and treatment features of patients suffering adrenal involvement with aPL to support the idea that APS leads to the development of adrenal insufficiency.

Abstract
BACKGROUND Catastrophic antiphospholipid syndrome (APS) is defined as life threatening multiple organ thromboses developing simultaneously or over a short period. The survival rate of catastrophic APS is about 50%, but the long term outcome of patients who survive is unknown. OBJECTIVE To determine the long term outcome of patients with catastrophic APS and provide further information on patients who survived. PATIENTS AND METHODS The clinical characteristics and outcomes of 130 patients with catastrophic APS have been reported previously. Six new cases were recently added to this series. Based on these publications, the authors who reported patients who had survived were contacted. Each author was asked (a) what treatment they gave their patients after the catastrophic APS; (b) if their patients had any further thrombosis. RESULTS 63/136 (46%) patients died at the initial event. Of the remaining 73 patients, information was available for 58 (79%). Thirty eight (66%) patients did not develop further APS related events during an average follow up of 67.2 months. Eleven (19%) patients developed further APS related events but were still alive. No patients developed further catastrophic APS. Nine (16%) patients died: due to multiple organ failure (three patients); myelofibrosis (one); pneumonia (one); and APS related events (four). CONCLUSION Sixty six per cent of patients who survive an initial catastrophic APS event remained symptom free with anticoagulation during an average follow up of 67.2 months. Twenty six per cent of the survivors developed further APS related events and the mortality rate of these patients was about 25%.

Abstract
Antiphospholipid antibodies (aPL) may induce acquired activated protein C resistance (acquired APCR). The role of acquired APCR in patients with systemic lupus erythematosus (SLE) is not well known. To evaluate the prevalence of acquired APCR and its association with clinical manifestations we studied 103 consecutive SLE patients and 103 matched controls. APCR in the undiluted test and after dilution in factor V deficient plasma, factor V Leiden, protein C and S, lupus anticoagulant, and anti-cardiolipin, anti-beta2-glycoprotein I and anti-prothrombin antibodies were determined. Factor V Leiden was found in 4% in both patients and controls. The prevalence of acquired APCR was 22% for the undiluted assay and 17% in the diluted test. In SLE patients, acquired APCR was associated with aPL (39 vs 13% in undiluted assay, P = 0.007; and 33 vs 7% in the diluted test, P = 0.001). Arterial thromboses were found in 24% of patients with acquired APCR and in 6% of patients without (P = 0.04). However, no relationship was found with venous thrombosis. Acquired APCR was also associated with pregnancy losses: miscarriages in 70% of women with acquired APCR vs 32% in those without (P=0.03). Thus, in SLE patients acquired APCR seems to be associated with increased prevalence of arterial thrombosis and pregnancy losses.
