Systemic lupus erythematosus (SLE) is not a rare disease. There are several common clinical signs which should alert the physician to a possible diagnosis of SLE and which should condition him to look for specific clinical and laboratory findings. In addition to simple screening tests, useful procedures include a search for antinuclear antibodies, lupus erythematosus (LE) cells, anti-DNA antibodies and low serum complement. Management is determined by the type of course encountered but most patients will do well under the care of their family physician.

The levels of C3, C4 and CH50 in patients with lupus erythematosus disseminatus (LED) were lower than in the controls. However, although in many patients these levels were below the normal values, there was no statistically significant difference between the two group. The levels are reduced during the acute phases and in some patients they remain high. On the whole, C3 was lower in patients with nephropathy (p less than 0,025) than in patients presenting with clinical activity (p less than 0,02). The positive relationship existing between C3 and C4 (r = 0,641, p less than 0,01) suggests activation of the complement system in LED via the classic route. In cases with concurrent lupus nephropathy a relationship between C3 and C3PA was seen, suggesting that in this case the alternative route is involved.

In 47 patients with systemic lupus erythematosus seen during fifty-one clinical episodes, oxygen-15, a short-lived gamma-emitting isotope, has been employed in a scannng technique to study cerebral oxygen utilisation and blood-flow. Abnormalities in regional distribution of oxygen utilisation and blood-flow were seen in twenty-three out of twenty-four instances of definite central-nervous-system disease, in fourteen out of fifteen instances of suspected C.N.S. lupus, and in ten out of twelve instances in which C.N.S. disease was not clinically apparent. The technique reflected remissions and relapses. It may prove valuable in diagnosis of subclinical cerebral disease, in monitoring of responses to therapy, and in study of the pathophysiology of cerebral lupus.

In the course of a prospective study of 165 patients with SLE a subgroup of eight patients with active SLE yet with persistently negative tests for ANF and LE cells was identified. These patients were characterized by a photosensitive skin rash with a negative lupus band test, a high incidence of arthritis, mild form of renal disease, and a positive family history for connective tissue disease. Antibodies to DNA and cytoplasmic antigens were detected in a few.

Isolation of type C oncornavirus was attempted from 20 tissues and cell cultures of patients with systemic lupus erythematosus. Chemical inducers, cocultivation and fusion with cells from multiple other species, prolonged subculturing, and the RNA-dependent DNA polymerase assay for virus detection were used. A type C virus was isolated, but was shown to be the endogenous rat virus. Thus the methods, although generally appropriate, were not specifically permissive for replication of a human type C virus. This agrees with the failure of other investigators to isolate a virus of undisputed human origin. Combining available evidence, a fundamental role for type C viruses in lupus erythematosus remains an attractive hypothesis.

A putative retravirus was isolated from a cell culture derived by fusion of mink and dog cell lines with cultured placental cells from a patient with systemic lupus erythematosus. The virus was detected by reverse transcriptase assay of supernatant medium after prolonged subculturing. Its characterisation, including species of origin, is in progress, but it is probably a new type C virus. Its role, if any, in lupus erythematosus in unknown.

In 4 women lymphomas developed 2 months to 12 years after the onset of systemic lupus erythematosus. An association between the two diseases had previously been reported in 14 cases, in 6 of which the lymphoma either preceded or was diagnosed at the same time as the autoimmune disease. In systemic lupus erythematous early biopsy of suspect lymph-nodes is recommended.

A 44-year-old white man presented with an erythemato-squamous rash in the supra-orbital and preauricular regions of the face. The diagnosis systemic lupus erythematosus was confirmed by histopathology, immunofluorescence (circulating antinuclear antibodies and a positive lupus band test), and by immunoelectron microscopy. Further examinations disclosed a multiple myeloma of the IgG type without cutaneous involvement. The coexistence of these two disorders has not been reported previously.

163 patients with diffuse lupus glomerulonephritis, proven by renal biopsy, were divided into four therapeutic trial groups: 67 were put on corticosteroids alone, 11 on corticosteroids and azathioprine, 32 on corticosteroids and cyclophosphamide, and 53 on corticosteroids and chlorambucil and were followed up for several years. The addition of azathioprine to corticosteroids did not increase the survival rate, improve the renal function or alter the grim prognosis of the patients. Cyclophosphamide appeared to influence favourably the pathological lesion and the renal function when added to corticosteroids, and the disease progressed at a slower rate. The fatal side effects nearly balanced the therapeutic value of cyclophosphamide. Patients on corticosteroids and chlorambucil had an excellent course. This therapeutic regimen resulted in resolution or regression of the renal pathology, marked improvement of the renal function and marked improvement of the survival rate. The authors believe that this therapeutic regimen holds the best chance of becoming the standard treatment for lupus nephritis, particularly since the side effects of chlorambucil were minimal.

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.
