In the literature, there are descriptions of single cases of ulcerative colitis (UC) and systemic lupus erythematosus (SLE) coincidence in the same patient. The association of these two autoimmune diseases might be explained by etiopathogenetic factors that they have in common. Recently there have been two patients observed (48 and 31-year old) in whom two and three years (respectively) after diagnosing ulcerative colitis, symptoms of chronic nephropathy showed up (i.e. chronic glomerulonephritis and mild renal failure, respectively). Both of them fulfilled the ACR criteria for SLE. Clinical features and results of laboratory tests allowed the authors to recognize SLE with renal involvement (lupus nephritis in one and nephropathy in the course of secondary antyphospholipid syndrome in the other patient). In both cases drug-induced lupus like syndrome was taken into consideration in differential diagnosis (as both of the patients were previously treated with sulphasalazine) but clinical features and long lasting follow-up after sulphasalazine withdrawal allowed the authors to recognize association of SLE with concomitant nephropathy and UC. In the presented article the problems of differential diagnosis of drug-induced lupus-like syndromes from SLE coexisting with UC are discussed.

Systemic lupus erythematosus (SLE) is an autoimmune disease characterised by excess autoantibody production. It typically affects women of childbearing age. Antiphospholipid antibody syndrome (APLAs) is associated with serious co-morbidity to mother and child characterized by recurrent vascular thrombosis and/or pregnancy associated morbidity. We reviewed SLE patients attending a specialist connective tissue disease clinic both to assess the occurrence of APLAs and its clinical presentations and to audit the effectiveness of screening for APL antibodies in a specialist clinic. 204 patients attended the newly established connective tissue disease outpatient clinic over a twenty-seven month period; 42 (34 female, 8 male) with a diagnosis of SLE. Ten patients (24%), eight female and 2 male with a median age of 38.5 years (range 20 to 64 years) fulfilled the ACR criteria for secondary APLAs (Table 2). The commonest clinical presentation was pulmonary embolus (five patients). Overall 37 patients (88%) with SLE were screened for APLAs during the study period: 94% of females and 62.5% of males were screened (for anticardiolipin antibodies, lupus anticoagulant or both), 27% had evidence of APLAs, 24% had positive antibodies but were asymptomatic. There is a significant occurrence of APLAs among SLE patients. Given the important clinical implications of this disorder including substantial risk of fetal loss and patient morbidity or mortality, routine screening of all SLE patients for APL antibodies is recommended.

The aim of this study was to describe the clinical manifestations and outcomes of a national cohort of childhood systemic lupus erythematosus (cSLE). All cases of cSLE registered in the Israeli national registry of children with rheumatic diseases between 1987-2003 were examined for disease activity and damage by the SLE disease activity index (SLEDAI) and SLE collaborating clinics/American College of Rheumatology (SLICC/ACR) damage index. Demographic, clinical, laboratory and treatment factors were analysed for their effect on the outcome. One-hundred and two patients were identified, 81% females, with a mean age at diagnosis of 13.3 +/- 2.6 years. The mean SLEDAI score was 17.2 +/- 9.0 (range 2-60). Fifty four patients were followed for at least five years. The mean SLEDAI decreased to 7.6 +/- 6.3 (0-29) and the mean SLICC/ACR damage index was 0.7 +/- 1.6 (0-8). Five patients developed chronic renal failure. No patients died. No factors were found to be significantly associated with the outcome except the initial SLEDAI score. The five-year outcome of our national cSLE cohort was good; with relatively low activity and minimal damage in most patients. The initial SLEDAI predicted the development of late damage.

The goals of this study were to ascertain damage in patients with systemic lupus erythematosus (SLE) from five rheumatologic centres in Argentina and to examine overall damage, damage by domain and damage by item within each domain. We performed a retrospective observational study including patients with SLE (ACR 1997 revised and modified criteria) from five rheumatology centres in Argentina. Organ damage was scored using the SLICC/ACR DI (SDI), ascertained at years 1, 2, 5 and 10. Three centres provided information up to the fifth year. Of the 197 patients, 88.3% were women and their mean age was 33.2 years. The mean disease duration and follow-up were 7.6 and 5.3 years, respectively. Damage accrued gradually over time with SDI ranging from 0.52 (+/-1.1) at year 1 up to 2.46 (+/-2.1) at year 10. The renal system was the most involved system, followed by the neuropsychiatric, the cardiovascular and the musculoskeletal systems. Proteinuria, cognitive impairment, pericarditis, avascular necrosis, cataract and alopecia were the predominant items in their respective systems. Systems such as peripheral vascular, pulmonary, gastrointestinal, diabetes, malignancy and premature gonadal failure were not frequent. Overall SDI had a gradual increase over time. Damage in each domain of SDI, except for diabetes, had a similar behaviour. Behaviour of items in each domain varied.

Deficiency of mannan-binding lectin (MBL) has been reported to impact susceptibility to severe infections and atherosclerosis in systemic lupus erythematosus (SLE). In this study, MBL gene polymorphisms were analysed in 143 SLE patients and the frequency of severe infections and organ damage according to SLICC/ACR Damage Index regarding cerebrovascular accidents, angina pectoris, coronary by-pass surgery, myocardial infarction and peripheral arterial disease leading to significant tissue loss, were recorded during a mean follow-up time of 15 years from diagnosis. In a multiple logistic regression model, smoking (P = 0.001), hypertension (P = 0.030), alcohol intake (P = 0.027) and higher triglyceride concentration (P = 0.026) were associated with cerebrovascular, cardiovascular and peripheral arterial organ damage (CPAD), while the association with MBL deficiency did not reach significance (P = 0.098). Alcohol intake (>15 g/month) was inversely correlated with CPAD (OR = 0.29, 95%CI 0.096-0.87). MBL deficiency was not significantly more common in SLE patients with severe infections in a multivariate analysis (P > 0.3). In conclusion, classical risk factors such as smoking, hypertension, low alcohol intake and elevated triglyceride concentration were relatively more important for development of CPAD than MBL deficiency in SLE. Furthermore, MBL deficiency did not contribute to development of major infections in SLE.

Thirteen patients with systemic lupus erythematosus and depression (Depressed-SLE), 10 Depressed-Control subjects, and 25 Healthy Control subjects completed cognitive testing and self-report questionnaires of pain, depression, and fatigue. The Depressed-SLE group scored higher on the American College of Rheumatology Neuropsychological Battery for systemic lupus erythematosus cognitive impairment index compared to Depressed-Control and Healthy Control subjects (p < 0.05 and p < 0.02, respectively). No correlations between cognitive impairment and pain, fatigue, or perceived cognitive failures were observed in the Depressed-SLE participants. Moderate agreement (86.4%) was found between a comprehensive neuropsychology battery cognitive impairment index and the ACR-SLE impairment index in the Depressed-SLE patients. Overall, the magnitude and pattern of cognitive impairment in Depressed-SLE patients cannot be explained by depression alone.

Antinucleosome antibodies (AnuA) are increasingly recognized as an important biomarker in the diagnosis and subset stratification of patients with systemic lupus erythematosus (SLE). The aim of the study was to determine the sensitivity, specificity, and clinico-serological correlates of AnuA in black South Africans with SLE. We performed a cross-sectional study of 86 SLE patients attending a tertiary center and 87 control subjects. AnuA were tested using a second-generation enzyme-linked immunosorbent assay (ELISA). The sensitivity, specificity, positive predictive value, and negative predictive value of AnuA were 45.3, 94.3, 88.6, and 63.6%, respectively. The presence of AnuA were strongly associated with the co-presence of anti-dsDNA antibodies (OR = 3.4, p < 0.0005) and antihistone antibodies (OR = 15.7, p < 0.00001). Patients who were seropositive for AnuA were more likely to have skin involvement (discoid lupus and/or malar rash) and had higher SLE disease activity index (SLEDAI) scores and Systemic Lupus International Collaborative Clinics/American College of Rheumatology (SLICC/ACR) damage scores (p < 0.05). IgG anticardiolipin antibody (aCL) levels showed a significant correlation with AnuA ratios (p < 0.01). Our findings provide further evidence that AnuA are a sensitive and specific diagnostic biomarker in SLE. Moreover, our finding that the presence of AnuA, but not anti-dsDNA antibodies, are associated with worse SLICC/ACR damage scores suggest that AnuA may have a role in predicting disease outcome. The correlation between IgG aCL and AnuA is a novel finding that merits further studies to determine possible common peptide specificities of the antibodies.

The LE cell has been one of the first immunological signs of active systemic lupus erythematosus, included into the ACR criteria. LE cells consist of a phagocyte engulfing material of disputed origin, which was interpreted as either cellular remnants from necrotic cells or as early apoptotic cells. It is well established that LE cell formation is dependent on autoantibodies against the linker histone H1. In view of this fact, we investigated whether anti-histone H1 antibodies and LE cell positive sera bound to cells where apoptosis had been induced by gliotoxin or actinomycin D or which were necrotic after heating. Necrotic cell remnants, but not (early) apoptotic cells were bound by anti-histone H1 antibodies and LE cell positive sera, establishing that the process of LE cell formation, which is dependent on anti-H1 binding, leads to engulfment of necrotic (or late apoptotic) material, but not of early apoptotic cells.

Psychiatric abnormalities are common in systemic lupus erythematosus (SLE) with a prevalence of 17% to 75%, reflecting different methods of patient selection and assessment, the different professional orientation of clinicians, and lack of an accepted consensus for diagnosing active neuropsychiatric lupus (NPSLE). The psychiatric syndromes included in the ACR Neuropsychiatric Lupus Nomenclature Committee criteria are cognitive dysfunction, acute confusional state (delirium), anxiety disorder, mood disorder, and psychosis. In SLE patients, identification of psychiatric phenomena and the generation of a differential diagnosis are crucial. Possible mechanisms include vascular injury and pathogenic antibodies. Treatment strategies are based on small case studies. The purpose of this review is to discuss clinical manifestations, pathogenesis and the present therapeutic options in psychiatric lupus.

Systemic lupus erythematosus (SLE) is a clinically diverse, complex autoimmune disease which may present with coincident onset of many criteria or slow, gradual symptom accrual. Early intervention has been postulated to delay or prevent the development of more serious sequelae. One option for treatment in this setting is hydroxychloroquine. Using 130 US military personnel who later met ACR SLE criteria, a retrospective study of onset, development and progression of SLE with and without pre-classification hydroxychloroquine (n = 26) use was performed. Patients treated with hydroxychloroquine prior to diagnosis had a longer (Wilcoxon signed rank test, P = 0.018) time between the onset of the first clinical symptom and SLE classification (median: 1.08 versus 0.29 years). Patients treated with prednisone before diagnosis also more slowly satisfied the classification criteria (Wilcoxon signed rank test, P = 0.011). The difference in median times between patients who received NSAIDs before diagnosis, as opposed to those who did not, was not different (P = 0.19). Patients treated with hydroxychloroquine also had a lower rate of autoantibody accumulation and a decreased number of autoantibody specificities at and after diagnosis. These findings are consistent with early hydroxychloroquine use being associated with delayed SLE onset. A prospective, blinded trial testing the capacity of hydroxychloroquine to delay or prevent SLE in high risk populations is warranted.
