This study describes the clinical and laboratory features and the natural history of 31 patients with late onset (in the sixth decade or later) systemic lupus erythematosus (SLE). Patients with late onset SLE constitute a distinct subset of the general lupus population that accounts for approximately 12 per cent of the cases. Advanced age modifies the expression of SLE in terms of clinical presentation (pleuritis and/or pericarditis are the most common presenting manifestations) and pattern of organ involvement (pulmonary abnormalities are more common, whereas lymphadenopathy, Raynaud's phenomenon, neuropsychiatric disease, alopecia and skin rash are less common). Because SLE is not usually considered to be a disease that affects the elderly, and because the pattern of SLE in the older age group may differ substantially from the seen in younger patients, there is often a delay in diagnosis (median of 10 months, with a delay of over one year in 32 per cent of patients). In light of the high incidence of steroid complications in older patients (40 per cent in our series), and because these patients with SLE have a relatively good prognosis (five year survival of 92.3 per cent; nine year survival of 83.1 per cent), therapy should be more conservative in late onset SLE.

The mixed connective tissue disease syndrome has been described in the medical literature. The clinical and serological characteristics of the syndrome are defined in this paper. The hands of these patients differ from the hands of patients with systemic lupus, rheumatoid arthritis, or systemic sclerosis. In 10 patients there were no erosive changes on radiological examination and all 10 patients had Raynaud's phenomenon. The most striking finding was tightness in the flexors. Mild cases of flexor tightness improved with systemic steroids. One patient with severe flexor tightness required surgical release of adhesions from a chronic inflammatory process of fascia, muscle, and tenosynovium. Biochemical studies showed an abnormal collagen pattern that may be distinct for mixed connective tissue disease.

Clinical and laboratory findings were correlated from 46 patients with IgG localization in epidermal nuclei in a speckled (particulate) pattern on direct immunofluorescence of normal skin. Cutaneous manifestations included lupus erythematosus (LE), swollen hands or sclerodactyly, alopecia, vasculitis, and dyspigmentation. Systemic manifestations included arthritis or arthralgia, Raynaud's phenomenon, serositis, vascular headaches, mild renal disease, myositis, and sicca syndrome. High titer (mean = 1:142, 800) serum antibody to extractable nuclear antigen (ENA) was found in 81%. Eighty-six percent had antibody to an RNase-sensitive antigenic component of ENA (ribonucleoprotein or RNP); 14% had antibody to an RNase-resistant ENA termed Sm. Deposition of IgG in a speckled pattern in epidermal nuclei is an immunopathologic marker for a subset of connective tissue disease characterized by antibody to ENA. Those with Sm specificity had systemic LE (SLE); Those with RNP specificity had Raynaud's phenomenon usually associated with overlapping features of SLE, scleroderma, and/or dermatomyositis.

Antibodies to histones were investigated in the serum of forty-five patients with spontaneously occurring systemic lupus erythematosus (SLE) who were not receiving any form of treatment. Twenty-three had active and twenty-two had inactive disease. Thos with active disease were also studied after the initiation of corticosteroid treatment to determine the effect of treatment on anti-histone antibodies. Both a complement fixation method and indirect immunofluorescence of acid-eluted histone-reconstituted tissue sections were used, with excellent correlation between these two methods. Eleven of the forty-five SLE patients, but none of forty-five normal controls had antibodies to histone. Untreated patients with active and inactive disease had a similar incidence of antibodies to histone. They disappeared, however, soon after the initiation of treatment in the patients with active disease. Patients with antibodies to histones had a higher prevalence of cutaneous vasculitis, anaemia, lupus nephropathy and Raynaud's phenomenon, but a lower prevalence of lupus brain involvement than those without such antibodies. Only the latter, however, reached statistical significance.

The coexistence of organ-specific and nonorgan-specific autoimmune diseases is an interesting phenomenon. A 52-year-old woman was admitted with fever, general discomfort, polyarthritis, and Raynaud's phenomenon. Physical examination revealed a goiter of stony consistency, hardening, paleness, and atrophy of the skin on the face and upper limbs, and blood hypertension (180/110 mmHg). The biological data included leukopenia, moderate anemia, and a very high sedimentation rate. The latex test was positive (+++); LE cells positive (+); hypergammaglobulinemia (3.5 g); antinuclear antibodies, 1/1280 with an immunofluorescence granular pattern; antithyroid antibodies, 1/160. There was pulmonary, renal, and gastrointestinal involvement compatible with scleroderma, which was confirmed by skin biopsy. A thyroidectomy revealed the existence of a papillary carcinoma with thyroiditis. Responde to treatment with immunosuppressive agents, hypotensive drugs, and thyroid substitution therapy was initially good. The patient was readmitted 8 months later with general discomfort and a severe hyperproteinemia (10 g/100 ml), including 65 percent gammaglobulin and requiring various sessions of plasmapheresis. The patient was discharged, but died suddenly 4 months later. The association of lupus and scleroderma in this patient is discussed and the possibility of its being a mixed connective tissue disease is discarded. The association of this condition with Hashimoto's thyroiditis, and the latter with papillary carcinoma of the thyroid are analyzed. The peculiar features of this case are pointed out. The authors postulate that the cause of the sudden death was a vascular cerebral complication induced by the extreme hyperproteinemia.

The changing pattern of clinical features of and prognosis for 206 patients with SLE were studied. SLE patients with Raynaud's phenomenon and minimal change and focal proliferative glomerulonephritis observed by means of renal biopsy tended to increase in C (1972--76) group compared with A (1955--68) and B (1969--71) groups. SLE patients with lupus nephritis and central nervous system lupus treated with large doses of steroids or combined therapy of steroids and immunosuppressive agents also increased in the order C, B, and A group. The prognosis for group C patients was better than that for A and B group patients. However, there appeared to be an increasing incidence of complications unrelated to SLE, namely infection and perforated peptic ulcer.

A computer analysis was made of the data from a prospective study of the clinical course of systemic lupus erythematosus (SLE) in 234 patients followed for an average of 46 months. All fulfilled four ARA criteria for the diagnosis of SLE. Sixteen of the 234 patients were aged 51 or older. They were compared with the 218 younger SLE patients to determine the influence of age on the signs and symptoms of the disease, the organ systems involved, the laboratory data, amount and duration of corticosteroid or azathioprine therapy, and the prognosis. The older group showed more discoid lupus, photosensitivity and pulmonary fibrosis than did the younger group, but a similar incidence of malar rash, alopecia, arthritis, arthralgia, myalgia and serositis, and a lower incidence of oral ulcers, Raynaud's phenomenon, cutaneous vasculitis, neuropsychiatric manifestations, leukopenia, hypocomplementemia and profus proteinuria. The older patients needed a lower dosage of corticosteroids, and a shorter course of azathioprine therapy. These findings suggest a milder form of SLE with better response to therapy in the older group.

Two sisters had autoimmune responses to the U1RNP particle that were quantitatively similar and/or identical in molecular characteristics. No other autoantibodies were demonstrable. Both sisters immunoprecipitated only U1RNA, had a reaction of identity in gel diffusion, bound the 68-kDa band in HeLa cell extract in Western blot, and reacted almost equally to a rabbit anti-idiotypic reagent made against either sister's isolated anti-U1RNP Fab fragments. They both carried a DR4 allele, which has been associated with anti-U1RNP production in several studies. While the sisters both had Raynaud's phenomenon, their clinical pictures were otherwise dissimilar. One had a seizure disorder (Ju); the other had polymyositis and features of scleroderma (Je). In sister Ju, Raynaud's phenomenon was manifest for the first time in association with the appearance of precipitating anti-U1RNP.

A 38 year old woman with systemic lupus erythematosus (SLE) was admitted because of epigastralgia and fever. The diagnosis of SLE was made 22 years ago based on Raynaud's phenomenon, butterfly rash, hair loss, photosensitivity and positive antinuclear antibody. She had episodes of consciousness disturbance, transient visual disturbance of the left eye, and a necrosis of the left big toe. She underwent artificial arthroplasty of bilateral femoral heads 11 years ago, when multiple aseptic necroses of thirteen bones were found, and when anti-cardiolipin (CL) antibody was found to be positive. An echogram of abdomen suggested an obstruction of superior mesenteric artery (SMA) when she was admitted. Selective angiography revealed a complete obstruction of SMA and splenic artery, and incomplete obstruction of celiac artery. Conservative treatment with urokinase infusion and prednisolone 50 mg/day was not effective, and small intestine and right colon were resected on the 23rd hospital day. The pathological examination showed thrombosis of SMA. There was no evidence of arteritis or atherosclerosis. Anti-CL antibody and lupus anticoagulant were positive on admission, but the level of both anti-DNA antibody and complement was normal. Therefore, it was suggested that the thrombosis was related with anti-phospholipid antibody. The characteristic clinical feature were multiple aseptic bone necroses and thromboses of several arteries. We discussed the relationship of thrombosis and the etiology of multiple bone necrosis in this case with anti-phospholipid antibody.

Using a detailed questionnaire, the cumulative historical and current demographic, clinical and serological data on 704 SLE patients from 29 European centres and 14 countries have been assessed. Ninety-three percent of the patients were Caucasian and the female/male ratio was 10:1. Analysis of the cumulative incidence showed that arthralgia/arthritis (94%), rash (69%), Raynaud's phenomenon (49%), serositis (44%) and renal disease (38%) were the most frequent clinical manifestations. Virtually all the patients (98%) were antinuclear antibody positive, while anti-ds-DNA antibodies (76%), hypocomplementaemia (71%) and anti-Ro(SSA) antibodies (35%) were frequent serological abnormalities. Whilst much of this data is in line with previous reports, it is notable that renal, lung, and central nervous system involvement and the frequency of rheumatoid factor, anti-Sm and anti-RNP antibodies were much lower than in most comparable series in the United States. We assume that ethnic differences and the greater present awareness of lupus could explain this variations. Low dose corticosteroids, non-steroidal anti-inflammatory drugs and anti-malarials were used to treat over half of the patients, 75% of whom were between 15 and 55 years of age. This report offers a useful overview of lupus both clinically and serologically in Europe in the 1990's.
