Eight attacks of transient global amnesia were observed in a female patient who suffered from livedo reticularis and a series of other neurological symptoms, which were transient in most stances. The neurological deficits include focal epileptic attacks, unilateral loss of vision, paresis of left arm and/or leg and dysarthria. The first amnestic attack was seen at the age of 19. The episodes lasted from a few to 3 days. The intervals between the amnestic episodes varied between a few days and 11 years. The livedo reticularis became more obvious during each neurological episode and was less pronounced during the time of remission. A benign type of essential hypertension and parproteinemia (gamma-M) was found. The investigations failed to show any evidence of essential thrombocythemia, polyarteriitis nodosa, lupus erythematodes and other immune complex diseases. The underlaying disease remained unclear.

The pathogenesis of the lupus erythematosus results from co-operation of three principles: (1) genetical disposition, (2) increased reactivity of the immune system, (3) different exogenic influences. The genetical disposition is confirmed by family investigations, metabolic disorders and immune anomalies as well as by parallels to animal models. The reaction manner of the immune system is genetically determined. Exogenic factors influence the immune system (behaviour) either as starter or by modifying the genetical material. The most striking humoral immune phenomenon is an immense number of (auto-)antibodies. Investigations of xeroderma pigmentosum as well as with DNA of different antigenity have shown that an increase of the antigenicity is unlikely for this phenomenon. In the serum of patients there were established and partially characterized factors (mitogens, granulocytic adherence-factor) for increasing the immune reactivity. The increase of such factors may be the sequence of a T-suppressor cell-defect. Like-wise no interdigitating cells in systemic lupus erythematosus have been found, cells which may be responsible for the terminal differentiation of T-lymphocytes. The mode of action of exogenic factors is represented and discussed with the example of the UV provocation.

The diagnosis of systemic lupus erythematosus (SLE) often depens on positive tests for antinuclear antibody, LE cells, and antibody to DNA. In fact, the presence of such serological markers is virtually required for the diagnosis of active disease. This report describes 5 well-studied patients with SLE who initially presented with negative serology despite active multisystemic disease. When followed from 10 months to 7 yr, negative serologic markers, including the ANA, LE cell test, and anti-DNA were seen to change from negative to positive, analogous to the seronegative rheumatoid patient who may become seropositive. In a few cases of lupus, therefore, negative serologic tests do not always exclude SLE, and serial testing at periodic intervals may be indicated.

Circulating immune complexes (CIC) were measured by three different methods in serum from 17 patients with systemic lupus erythematosus (SLE), 3 patients with "hydralazine-induced" SLE-like syndromes, 14 patients with discoid lupus (DLE), 8 patients with systemic sclerosis and 5 patients with dermatomyositis. Immune complexes were detected in 13 of the 17 patients with SLE. All patients with lupus nephritis and typical exanthema had circulating immune complexes. The concentration of immune complexes was inversely correlated to serum complements C4 and C3. All 3 patients with "hydralazine-induced" SLE-like syndromes had circulating immune complexes that disappeared after withdrawal of the drug. Immune complexes were detected in 3 of the 14 patients with DLE; all 3 patients with CIC had wide-spread DLE. In systemic sclerosis, CIC were detected in only 1 of the 8 patients. Four of the 5 patients with dermatomyositis demonstrated CIC in serum. No complement consumption was detected in dermatomyositis and the immune complexes may have been secondary to tissue destruction.

Anti-nucleus antibodies were detected in the blood sera of 232 patients of different pathologies by three diverse methods: a morphological method, and indirect immunofluorescent method and a radioimmunologic method. The results demonstrated the importance of the radioimmunologic method since this method displays anti-DNA antibodies which are specific in the active stage of lupus erythematosus (LE). Forthermore, the immunofluorescent method proved to be highly sensitive; and the morphological method can reveal different aspects of the LE phenomenon (such as nucleus phagocytosis) which can be indicative of an auto-aggressive process. Our survey indicates that simultaneous use of the three methods is advisable.

A 61-year-old man developed clinical lupus syndrome with positive antinuclear antibody, positive lupus erythematosus (LE) cell preparation, and diffuse proliferative glomerulonephritis following 26 months of procainamide therapy. He was treated sequentially with prednisone and azathioprine (2 weeks), decreasing doses of prednisone alone (21 months), and no immunosuppressive drugs (10 months). Coincidental with this treatment, the immunopathology of the glomerulonephritis improved dramatically, dramatically, renal function returned almost to normal, and both antinuclear antibody and LE cell preparation became negative. The course of this patient's renal disease contrasts sharply with diffuse proliferative glomerulonephritis of idiopathic systemic lupus, and suggests that this rare complication of procainamide therapy may have a favorable course.

Myocardial involvement in lupus erythematosis takes the form of an interstitial myocarditis with cellular infiltration and fibrinoid necrosis. The most lesions are perivascular, and involve the arterioles. The myocardial fibres are involved secondarily to the vascular lesions, or by grossly, damaging sclerosis. The clinical features are variable:--no clinical features, but haemodynamic evidence of abnormal ventricular function, and perhaps sudden death;--arrhythmias and disorders of atrio-ventricular conduction;--cardiac failure, which may be due to a genuine cardiomyopathy (a part may be played by hypertension, pulmonary hypertension, renal failure, constrictive pericarditis or haemodynamically major valve disorders);--abnormalities of the coronary trunk in a certain number of cases. If anti-nuclear antibodies are present in a cardiomyopathy, the presence of DLE or of a drug-induced lupus syndrome must be suspected. There remain some awkward cases which defy classification, and which systematic use of echocardiography and pericardial and myocardial biopsy may be able to define more accurately.

There appears to be an association between deficiencies of a number of complement components, particularly of the second component (C2), and rheumatic diseases, especially lupus. The meaning of this association is not clear, but the linkage of deficiency of C2 with HLA, especially HLA-A10, B18, Dw2, as well as with BfS, suggests a possible linkage to immune response genes.

Serum C-reactive protein (CRP) concentration was determined by a radial immunodiffusion method in serum samples collected over a mean period of 19 months from a group of 17 patients with systemic lupus erythematosus (SLE). Thirty-two episodes of CRP elevation were detected. Twenty of these were associated with active SLE, and 9 with proven or possible infection or bone fracture. In 3 cases no explanation for CRP elevation was readily apparent. There were 8 instances of onset or exacerbation of lupus activity without accompanying CRP elevation. These data indicate that CRP elevation in the course of SLE is frequently associated with activation of lupus, and that detection of such elevation does not differentiate between lupus activity and infection.

Synovial fluid C3 was measured by electroimmunoassay. When C3 was expressed as mg/ml, the amounts found in Reiter's disease, psoriatic arthritis, gout, and systemic lupus erythematosus were significantly different from degenerative arthritis. When C3 was corrected for total protein, the levels for rheumatoid arthritis, Reiter's disease, psoriatic arthritis, and systemic lupus were significantly different from degenerative arthritis. When C3 was corrected for synovial fluid globulin, only rheumatoid arthritis and systemic lupus were significantly different from degenerative arthritis. Correction of C3 for globulin increases the difference between rheumatoid arthritis and degenerative arthritis. A proportion of gouty fluids with a relative decrease in C3 is demonstrated. It is argued that correction of C3 for globulin is more meaningful than correction for total protein. While many nonrheumatoid inflammatory effusions demonstrate split products of C3, the majority of fluids from patients with systemic lupus have none.
