The long-term prognosis for SLE has improved markedly in recent decades because of earlier diagnosis and optimized treatment. Further research and randomized controlled trials are needed for the development of specifically targeted therapies.

To investigate the safety and efficacy of oral methylprednisolone combined with azathioprine sodium or mycophenolate mofetil for the treatment of bullous pemphigoid.Design: A prospective, multicenter, randomized, nonblinded clinical trial to compare 2 parallel groups of patients with bullous pemphigoid undergoing different treatments.Setting: Thirteen departments of dermatology in Germany.Patients: Patients with bullous pemphigoid (n=73) as evidenced by clinical lesions suggestive of bullous pemphigoid, signs of subepidermal blistering on histologic analysis of skin biopsy specimens, linear deposition of IgG and C3 along the dermoepidermal junction, and deposition of autoantibodies at the blister roof in split-skin analysis.Interventions: Treatment with oral methylprednisolone plus azathioprine (azathioprine group) or oral methylprednisolone plus mycophenolate mofetil (mycophenolate mofetil group). Main Outcome Measures:The cumulative total methylprednisolone doses and rates of remission. Secondary outcome measures were safety profiles and duration of remission.

The therapeutic effect of thalidomide in chronic discoid lupus erythematosus (CDLE) was studied in sixty patients who were followed up for 2 years. In fifty-four patients (90%) a complete or marked regression of the disease was observed, but when the thalidomide was stopped, thirty out of forty-one (71%) patients relapsed. Patients undergoing a second course of thalidomide treatment again responded well. Nine of the patients in whom the disease recurred after successful treatment with thalidomide and who had been unresponsive to intermittent treatment with antimalarials, showed a good response to a second or third course with thalidomide. Mild side-effects were common and 25% of patients complained of slight to moderate polyneuritic symptoms. Since electroneurological examinations had not been performed before the thalidomide therapy, the frequency of neurological side-effects cannot be accurately calculated but we recommend neurological examinations before and periodically during thalidomide treatment. Thalidomide is a very effective drug in CDLE, but in most cases it exerts its effect only whilst treatment is continued. Its use should be restricted to patients resistant to topical steroids and systemic antimalarials.

Background Lupus erythematosus tumidus (LET) is a rare disease which was first described in 1909 but has not always been considered as a separate entity of cutaneous lupus erythematosus (CLE) in the international literature. Objectives To compare characteristic features of different subtypes of CLE and to analyse whether LET can be distinguished as a separate entity in the classification system of the disease. Methods The study involved 44 patients with CLE, including 24 patients with LET, 12 with discoid lupus erythematosus (DLE) and eight with subacute CLE (SCLE), from two centres in Germany. A core set questionnaire and an SPSS database were designed to enable a consistent statistical analysis. Results Location of skin lesions did not differ significantly between the CLE subtypes; however, the activity score was significantly lower in LET than in DLE (P < 0.01), and the damage score was significantly lower in LET than in SCLE (P < 0.01) and DLE (P < 0.01). Photosensitivity and antinuclear antibodies were confirmed to be different in LET compared with SCLE and DLE but without statistical significance. Moreover, histological analysis of skin biopsy specimens showed that abundant mucin deposition is significantly more present in LET compared with SCLE (P < 0.01) and DLE (P < 0.01) while prominent interface dermatitis and alteration of hair follicles were absent in LET. Conclusions Several significant differences were found between LET and other subtypes of CLE with regard to clinical, histological and laboratory parameters. These data strongly indicate that LET should be defined as a separate entity in the classification of CLE.
