Haematological studies were carried out in hydralazine-induced collagen-like syndrome in guinea pigs. 37.5 per cent of animals were found to be LE-positive. It was found that long-term administration of hydralazine caused a decrease of erythrocyte count, a decrease of haemoglobin concentration and a decrease of haemoglobin content in individual red blood cell as well as a decrease of a single erythrocyte volume. A significant leukopenia was shown in LE-positive subgroup of hydralazine-treated guinea pigs. The obtained results confirmed the similarity of hydralazine syndrome to systemic lupus erythematosus.

Two patients with locally advanced carcinoma of the breast had radiation therapy as primary treatment. Within one year, a lupus-like syndrome developed characterized by pneumonitis, pleural effusion, and positive fluorescent antinuclear antibody (FANA) reaction and lupus erythematosus (LE) preparation. Pericarditis developed in one patient and leukopenia in the other. The bilateral pulmonary disease, serological abnormalities, and rapid and sustained response to administration of prednisone made the diagnosis of systemic lupus erythematosus more likely than radiation-induced disease or metastic carcinoma. Radiation to normal and/or malignant tissue may have initiated an immunological response leading to a lupus-like syndrome.

The present prospective study was designed to examine the diagnostic and prognostic value of lymphocytotoxins in 20 patients with Systemic Lupus Erythematosus both in active stage and in remission. Lymphocytotoxic antibodies were present in 79% of all the sera examined, in 100% of the sera of patients with active disease and in 52% of those in remission. The different frequency in the two groups is significant as well as the correlation of these antibodies with anti-DNA antibodies, hypocomplementaemia and leukopenia. In spite of their diagnostic value, lymphocytotoxins do not appear as sensible parameter as complementaemia and anti-DNA antibodies in monitoring the disease, since they are still detectable in the sera for several months after the disappearance of clinical signs of activity.

Investigation of 92 patients with discoid lupus erythematosus, manifested initially by localized cutaneous lesions only, showed abnormal laboratory test results for 57 patients (62%) on admission and for 62 patients (67.4%) on review 16 to 20 years later. Patients with discoid lesions confined to the head and neck (DLE) showed fewer laboratory abnormalities than those patients with disseminated lesions involving trunk and limbs (disseminated discoid lupus erythematosus [DDLE]). Systemic lupus erythematosus (SLE) eventually developed in six (6.5%) of the patients, and all had shown persistent multiple abnormal laboratory findings from the beginning. Complete remission occurred in 46.7%. A persistent positive antinuclear factor of either speckled or homogeneous pattern with a titer greater than 1:50, leukopenia, thrombocytopenia, or a false-positive Wassermann reaction indicated those patients who may progress to DDLE or SLE.

A white female infant who developed a sudden onset of gross hematuria and proteinuria at 3 months of age was referred for evaluation of nephrotic syndrome at 6 months. Laboratory investigations revealed severe Coomb's negative hemolytic anemia, leukopenia, thrombocytopenia, hypocomplementemia and elevated anti-nuclear antibody titer and DNA antibodies. Renal biopsy showed a membranous type of morphology. She was also found to have chromosome abnormalities. She had an eventual favorable response to steroid therapy. Systemic lupus erythematosus (SLE) is rarely seen in young infants and the renal expression of the disease found in our case has never been reported.

Results of a Double Blind Study: In a randomized double blind study, 22 patients were treated with levamisole. The intention was to find out whether immunostimulation would have a favorable influence on rheumatic complaints in patients with rheumatoid arthritis and whether an objectifiable improvement of the synovial reaction can be obtained. The course was monitored with an extensive laboratory diagnostic program in 13 patients treated with levamisole and 9 patients with placebo. The medicament did not cause a pseudo-LE syndrome. In the overall result, 84.6% of the patients were significantly improved compared to 33.3% of the placebo group. Gastric complaints were occasionally seen as side effects. In one patient, the treatment had to be interrupted several times because of recurrent leukopenia and was prematurely ended in the 21st week.

Data from a prospective study of the clinical course in 223 patients with systemic lupus erythematosus followed for 655 patient-years were analyzed by computer to determine the influence on frequency of infection of 1) corticosteroid dose; 2) azathioprine; 3) active disease, measured by new disease exacerbations, elevated ESR, hypocomplementemia, active urinary sediment, and proteinuria; 4) uremia; and 5) leukopenia. The frequency of all infections, and of bacterial and opportunistic infections specifically, increased progressively with increasing steroid dose. Azathioprine use, independent of steroid dose, did not account for an increased risk of bacterial, opportunistic, or nonspecific viral infections. Leukopenia did not predispose to infection, except possibly when associated with azathioprine-induced bone marrow suppression. Active renal disease, especially when manifested by abnormal urine sediment, was associated with an increase in infection frequency.

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.

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.

Although many examples of familial SLE have been reported, the relative importance of genetic and environmental factors remains unclear. In an effort to better understand these factors, eight such families were studied. These families, plus one deceased pair and 31 described in the literature consisted of 8 pairs of identical twins, one pair of non-identical twins, and 16 sibling and 15 parent-offspring combinations. Fifty-three cases in 25 families provided sufficient documentation for detailed analysis. Each familial case was compared to his affected relative utilizing 23 clinical and laboratory features of SLE. A control group of non-related SLE patients, each matched to a familial case for age, sex, race and disease duration, was similarly analyzed. Impressive concordance for disease expression was found between pairs of identical twins and between parent and offspring. No such concordance was found between siblings and controls. These findings support genetic influences in the expression of SLE in identical twins and parents and offspring pairs. Comparison of the frequencies of clinical and laboratory attributes in the familial group as opposed to non-familial groups showed no real differences. Thus, familial SLE is probably not a different disease entity from non-familial SLE. The finding of four father-offspring pairs lessens the possibility that SLE is transmitted during the perinatal period. The onset of SLE in each of identical twins occurred within an average of 2 years. In siblings, however, while the average difference in age at onset was 9 years, the average difference in time of onset (actual date) was only 3 years. Comparable figures for parents and offspring were 20 and 8 years, respectively. These data suggest environmental influences in the initiation of SLE, especially in siblings. Studies of 27 unaffected first-degree relatives in our eight families revealed two sisters with thyroid disease, persistent leukopenia and sedimentation rate elevation. They were daughters of a patient with SLE and Hashimoto's thyroiditis and sisters of a patient with SLE. The remaining 25 relatives were clinically, hematologically, biochemically, and serologically normal. While these studies suggest both genetic and environmental influences in the pathogenesis of SLE, further studies are necessary to elucidate the mechanisms.
