[Revision of the recommendations of the Commission on Pharmacotherapy of the German Society for Rheumatology. Comment on the use of mycophenolic acid for systemic lupus erythematosus].

According to the NIH scheme, the "evidence based medicine" standard in the treatment of severe proliferative lupus-nephritis is cyclophosphamide in combination with steroids. Undesired effects, therapy resistance, and deficient long-term effects underscore the necessity for the development of alternative therapies for the treatment of organ involvement. Mycophenolate mofetil (MMF) possesses the potential to decisively improve the therapeutic possibilities for systemic lupus erythematosus (SLE). On the basis of the available data, MMF represents an alternative to the current standard therapies for severe lupus-nephritises and shows less toxicity. MMF is also effective in patients with other manifestations refractory to conventional therapy. Questions remain unanswered on the optimal dosage and possible reduction in cases of remission. In addition, the duration of maintenance therapy is unclear. Therefore, large, prospective, randomized clinical studies in the treatment of lupus-nephritis with a sufficiently long follow-up phase are underway.

[Disability in lupus erythematosus].

Morbidity and co-morbidities in patients with lupus erythematosus (LE) result in an impairment, limiting activities of daily living. We compared the handicap, appraised by the German welfare system in patients with LE and their diagnosis, morbidities and co-morbidities, therapy, functional capacity, psychological status and general health. The data were obtained in an anonymous self-administered questionnaire conducted by the lupus patient association. 892 data sets were available for the trial. The mean age was 46.9y, disease duration was 10.3y. The patients had 3.8 concomitant diseases on average. 39.7% were still working and 35.4% drew a pension. 59.2% made an application for disability, which wasn't assigned in only 2.5% of cases. 82.6% had an average grade of disability of more than 50%. It demonstrated a good correlation to age, disease duration, type of LE and therapy. Predictors for a worse assessment were disease duration, osteoarthritis, cerebral insults and functional capacity. In conclusion the data demonstrate a fair appraisal of disability by the German welfare system in patients with LE. Self-administered questionaires can yield credible results.

Connective tissue diseases: evaluation of clinical response.

Systemic connective tissue diseases (CTDs) are disease entities characterized by a systemic and heterogeneous spectrum of clinical symptoms. The treatment of CDTs has improved substantially, but with the developments of new and probably more expensive targeted therapies, there will be a need of rigorous evaluation in patient-oriented research. Proposed domains for outcome measurement of CTDs are activity, damage by disease and/or medications and quality of life. To evaluate the overall disease activity in CTDs, scores are developed that include typical signs and symptoms. For example, in systemic lupus erythematosus (SLE), various activity instruments have been developed and validated. Recently, a definition for significant reduction in activity based on these scores was proposed and has now to be validated in clinical trials. In addition, the American College of Rheumatology has framed recommendations for response criteria of major target organs. Besides, the rarity of CTDs other than SLE and the rare therapeutic options, especially the heterogeneous disease expression, has prevented development of instruments scoring the disease activity. In individual patients, there is need for a more organ-specific evaluation, and non-disease-specific and/or global health instruments may be used in evaluating the response of individual treatment regimen.

Improvement of coping abilities in patients with systemic lupus erythematosus: a prospective study.

OBJECTIVE: To evaluate a novel specific psychological intervention aimed at improving coping in patients with systemic lupus erythematosus (SLE). METHODS: 34 community living SLE patients were recruited for the study. Intervention was undertaken in groups of up to eight patients and in two blocks over six months each. Eight patients were enrolled as a waiting list group. The 18 group sessions focused on information about the disease and specific problems of SLE patients, combining psychoeducative and psychotherapeutic elements. Psychological and medical evaluations were conducted at baseline and after three, six, and 12 months, using validated instruments. RESULTS: The 34 SLE patients (91% female, mean age 42 years) improved significantly over a six month period on most of the psychological measuring instruments applied, such as depression, anxiety, and overall mental burden. The waiting list group showed no significant changes. CONCLUSIONS: Conceptualised psychoeducational support may produce a significant and sustained improvement in coping skills of SLE patients and hence in their quality of life.

[Lupus in Germany: analysis within the German lupus self-help organization (LULA)].

During the last few decades, the prognosis for patients with systemic lupus erythematosus (LE) has changed from high early mortality to a more chronic longterm course. Although the prevalence of LE has been estimated at 20-50/100,000, data concerning the situation of LE patients in Germany are sparse. Since 2001, a documentation within the German Lupus Self-Help Organisation scheduled for a period of 10 years (LULA) has been recording at the patient level the actual status and the long-term course of a large group of LE patients. A questionnaire adapted from the German rheumatological database is updated once a year and sent to all members.In 2001, 1033 members participated in the documentation. Of these, 92.2% were women (mean age 45.8 years) with a mean disease duration of 9.9 years. 37.6% were employed, and 24.5% were on early retirement. 50.2% rated their overall health status as "not so good" or "poor". Most were receiving treatment with [hydroxy-]chloroquine (35.2%) or azathioprine (21.9%), while 67.9% were receiving corticosteroids. The most frequent comorbidities reported were hypertension (33%), scarring skin disease (24.4%), osteoarthritis (25.2%), osteoporosis (24%), psychiatric disorders/depression (22.9%) and chronic renal disease (22%). Thromboembolic events were reported in 18.5%, myocardial infarction in 2.3% and stroke in 4.8% of cases. Concerning their main contact person for health care, 63.6% specified the rheumatologist. In comparison with other cohort studies and in particular with the German rheumatological database, the data provided exclusively by patients are feasible. Concerning the severity of their disease, their treatment and their global assessment of health status, LULA participants are comparable with other LE patients and can be seen as representative of LE patients in Germany. Further assessment especially of long-term data are needed to obtain additional insights into the burden of the disease and the need for special medical care.

[Accelerated atherosclerosis in rheumatic systemic diseases as an example of systemic lupus erythematosus--what is the consequence?].

Large increases in mortality related to premature atherosclerosis with coronary artery disease and stroke have been reported during the last few years in patients with systemic lupus erythematosus (SLE). Studies found relative risks of 5 to 7 for myocardial infarction in SLE patients. The traditional risk factors fail to fully account for accelerated atherosclerosis in SLE and APS, in addition prolonged glucocorticoid therapy and long duration of SLE seem to be of importance. The disease SLE per se is an independent risk factor. The current pathogenic hypothesis for atherosclerosis involves an inflammatory response, autoantibodies, immune complexes (containing antibodies to phospholipids, to oxidized LDLs, and to endothelial cells), CD40/CD40 ligand interactions, and bacterial or viral infections responsible for an immune response. The determination of classic and new risk factors, together with specific autoantibody titers and the use of Doppler carotid ultrasound, are useful methods to detect early atherosclerosis. Therapeutic strategies, including early risk factor intervention and effective control of inflammation, are essential to reduce morbidity and mortality and should be incorporated into the management of connective tissue disease with the goal of protecting patients against atherosclerosis.

First clinical trials of a new heteropolymer technology agent in normal healthy volunteers and patients with systemic lupus erythematosus: safety and proof of principle of the antigen-heteropolymer ETI-104.

BACKGROUND: The heteropolymer technology was developed to remove pathogens from the circulation. OBJECTIVES: To evaluate the safety and tolerability of a single administration and to establish proof of principle for ETI-104 in normal healthy volunteers (NHV) and patients with systemic lupus erythematosus (SLE) METHODS: The drug was given intravenously to 11 NHV and six patients with SLE. Over 28 days, vital signs were noted, a haematological and chemical analysis of blood and urine was carried out, and adverse events were recorded. CR1 receptor numbers, the ability of antigen based heteropolymers to bind to red blood cells (RBCs), and the clearance of high avidity and total anti-dsDNA antibodies were measured by Farr assays and FACS analysis. RESULTS: No safety measure differed significantly from normal in both groups; no drug related serious adverse events occurred. ETI-104 rapidly bound to RBCs in NHV and patients with SLE. Binding of the drug to RBCs of patients with SLE also caused a rapid reduction of circulating anti-dsDNA antibodies in the plasma 15 minutes after administration, with a maximum reduction of 55% (range 43-62). At 28 days statistically significant decreases were maintained in three patients, while in the other three the values had returned to baseline levels. CONCLUSION: These clinical trials established the safety and the proof of principle of the new immunoconjugate ETI-104. This provides the basis for further development of this technology for numerous indications-for example, therapeutic options for autoimmune diseases or viral and bacterial infections.

Health care and burden of illness in systemic lupus erythematosus compared to rheumatoid arthritis: results from the National Database of the German Collaborative Arthritis Centres.

During the past 20 years, outcome studies in the rheumatic diseases have, on the one hand, given increasing evidence of the unfavourable long-term prognosis of rheumatoid arthritis (RA) and on the other hand determined continuous improvement of prognosis in systemic lupus erythematosus (SLE). The aim of the study was to investigate how this translates into the current spectrum of patients with rheumatoid arthritis (RA) or systemic lupus erythematosus (SLE) seen by rheumatologists in Germany and to compare aspects of the burden of disease, disease outcomes and treatment between these two important rheumatic diseases using a large clinical database. Current health care was analysed with data from the German rheumatological database of 10 068 patients with RA and 1248 patients with SLE seen by rheumatologists in 2001. In addition, of a total of 3546 patients with SLE and 24 969 patients with RA seen at the German Collaborative Arthritis Centres between 1994 and 2001, 3465 cases of SLE were matched by age, sex, disease duration and referral status with a corresponding RA case. There were considerable differences in treatment of patients before referral to a rheumatologist and in rheumatologic care. In 2001, patients with SLE were treated by their rheumatologists mainly with antimalarials (AM, 37%), azathioprine (29%) and nonselective NSAIDs (16%). Of them, 61% received at least one immunosuppressive drug (including AM) plus glucocorticoids. In RA, methotrexate was the predominant medication (63%), and 56% received at least one immunosuppressive drug plus glucocorticoids. Matched pairs analysis showed that SLE patients with a short disease duration were almost equally burdened by pain, functional limitations and reduced health status as RA patients. After a disease duration of >10 years, however, patients with RA showed poorer outcomes than those with SLE: RA patients reported significantly more often severe pain (30% in RA versus 17% in SLE) and poor global health status (52 versus 38%), and their disease activity as well as severity was rated higher by the rheumatologists. In conclusion, comparing large groups of RA and SLE patients we found a similar burden in early but not in late disease. Taking into account limitations as to the generalizability of the results (recruitment in rheumatologic care, cross-sectional data, underestimation of SLE-specific outcomes), the discrepancy between the high increase in disease-related negative outcomes with longer disease duration in RA but not in SLE indicates a better long-term prognosis in SLE concerning the items observed. The great disparity in treatment intensity between rheumatologists and nonrheumatologists shows that the involvement of a specialist is needed equally in both diseases.
