A 39 years old black woman with systemic lupus erythematosus developed tense bullae on erythematous bases on the flexor surfaces of the forearms and oral cavity. Some blisters healed with atrophy and pruritus was a striking feature. The diagnosis of systemic lupus erythematosus was based upon the following criteria: the typical blush in the butterfly area, alopecia, a painful macular papular eruption on the palms and fingers, fever, arthralgia, anemia, leukopenia, elevation of erythrocyte sedimentation rate and positive ANA. Histologic examination showed a subepidermal bulla formation and perivascular inflammatory infiltrate containing lymphocytes and eosinophils. By indirect immunofluorescence no autoantibodies were detected. Direct immunofluorescence showed deposition of linear IgG. High doses of prednisone brought about clinical remission but there was no response to sulfone. The patient is on maintenance dose. The authors discuss the differences between the three diseases and conclude that the bullous eruption cannot be classified.

Concurrent systemic lupus erythematosus (SLE) and amyloidosis (renal and splenic) are reported in a 7-year-old female miniature Schnauzer. Treatment of tissue sections with potassium permanganate and dilute sulphuric acid prior to staining with Congo red indicated that the amyloid in this case is composed of AA protein (i.e. reactive systemic amyloid or so-called secondary amyloid). The rare association of amyloidosis and SLE, in both man and the dog, and the association with granulomatous pneumonia and leukopenia in this case are discussed.

Sera from patients with systemic lupus erythematosus (SLE) directly stimulate polymorphonuclear leukocyte (PMNL) oxygenation activity as measured by luminol dependent chemiluminescence (CL). The stimulatory capacity of a serum, expressed as percent PMNL chemiluminescence (%CL), was calculated by dividing the integral CL response to the serum by the integral CL response to a standard stimulus, opsonified zymosan. Testing was performed on 50 sera obtained serially from 8 SLE patients and on 14 sera from 11 controls. Sera from SLE patients in remission and controls were nonstimulatory with mean %CL +/- SE values of 3.1 +/- 0.7 and 3.5 +/- 0.9, respectively. Sera obtained from the SLE patients during active disease yielded a mean %CL value of 26.6 +/- 9.0. The stimulatory capacity of SLE serum was concentration dependent and enhanced by adding normal serum complement. The CL response correlated with serological measures of SLE activity such as antibodies to double stranded DNA (p less than .0001) and Clq binding immune complexes (p less than .001). Thus, during active SLE, PMNL may become metabolically activated by exposure to serum containing immune complexes and possibly other factors. PMNL activation may contribute to the development of vasculitis, leukopenia, and susceptibility to infection. Our CL approach allows sensitive in vitro assessment of the phlogistic properties of serum to monitor SLE disease activity.

We have characterized 52 consecutive patients fulfilling 4 or more of the American Rheumatism Association criteria for systemic lupus erythematosus in order to provide, for the first time, a homogeneous sample for statistical comparison of antinuclear antibody (ANA)-positive and ANA-negative groups. Ten patients (19%) were seronegative. There was no significant difference in age, disease activity, organ system involvement, erythrocyte sedimentation rate, immune complex levels, or C3 levels. The ANA-negative group showed a higher incidence of involvement for whites and men. Leukopenia, lower levels of antibody to DNA, and higher C4 levels were also characteristic of the ANA-negative group.

The clinical and serologic features of 7 patients whose sera contained antibodies directed against proliferating cell nuclear antigen (anti-PCNA) were studied. Five of the patients had systemic lupus erythematosus (SLE), 1 had idiopathic diffuse proliferative glomerulonephritis, and 1 had seronegative arthritis. In a study of various rheumatic diseases, anti-PCNA was found in 2% of SLE sera but was not found in the sera of 100 rheumatoid arthritis patients, 20 mixed connective tissue disease patients, or 50 diffuse scleroderma patients. Patients with anti-PCNA had no history of hemolytic anemia, leukopenia, thrombocytopenia, or pleuro-pericarditis. Evidence that the production of anti-PCNA antibodies is sensitive to corticosteroid therapy is also presented.

Hematological abnormalities in scleroderma indicate a specific complication of the disease itself, or an associated illness. Among 180 patients with scleroderma, anemia was detected in 25% and was attributed to chronic inflammatory disease (usually an overlap syndrome), bleeding mucosal telangiectases as part of the CREST syndrome, intestinal malabsorption, and microangiopathic hemolysis. Leukocytosis, present in 14%, was correlated with active myopathy and/or advanced visceral involvement while leukopenia was suggestive of a crossover with systemic lupus erythematosus. Thrombocytopenia was often a manifestation of microangiopathy, and thrombocytosis was associated with an arteritis or a tumor syndrome.

A patient with Graves' disease who experienced various allergic reactions to both PTU and MMI is reported. She developed fever, skin rash, lymphadenopathy, liver damage and moderate leukopenia during PTU administration. Furthermore, she developed an MMI-induced lupus-like syndrome characterized by generalized lymphadenopathy, migrating, polyarthritis and myalgia, and results of tests for anti-DNA antibody and anti-nuclear antibody, and LE were positive. All these abnormalities reverted to normal upon discontinuation of medication after subtotal thyroidectomy.

Patients with active systemic lupus erythematosus (SLE) often have circulating antibodies to T cells. These patients also often have leukopenia and diminished numbers of T lymphocytes. In addition, certain T lymphocyte functions are frequently impaired in patients with SLE. It has been previously considered that a complement-dependent cytotoxic mechanism was responsible for the above observations. We now demonstrate that antibody-dependent cell-mediated cytotoxicity (ADCC), a cytotoxic reaction mediated by antibody and effector cells in the absence of complement, can also kill T cells from normal individuals as well as from patients with SLE. Moreover, this ADCC could be observed using the plasma, effector cells, and target cells all obtained from the same individual with SLE. Plasma of those patients with active SLE, and in whom anti-T cell antibodies could be demonstrated by the more classical complement-dependent cytotoxicity, was most often able to mediate such an ADCC reaction. The IgG fraction of the plasma was responsible for inducing ADCC, and aggregated IgG could block the reaction. The fact that the IgG fraction was often more effective than the unfractionated plasma suggested that immune complexes present in SLE plasma might partially block the expression of ADCC. Because a single SLE plasma could induce ADCC in T cells from several different unrelated individuals, it is unlikely that antibodies directed against particular human leukocyte antigens (HLA) or blood group antigens are involved.

Thirty patients with systemic lupus erythematosus (SLE) were studied over a 2.5-year period. The group was divided into 14 patients with antibodies to Sm and a control group that failed to exhibit antibodies to Sm over the study period. The titer of antibodies to Sm fluctuated in all 14. A rising titer of antibodies to Sm 1) predicted a flare disease in 50% an 2) correlated with an exacerbation of disease in 60%. Patients with antibodies to Sm had a comparable incidence of severe disease, renal disease, and central nervous system disease. They exhibited significantly more leukopenia and antibodies to non-Sm, non-RNP extractable nuclear antigen. In only 1 patient, a rise in titer of antibodies to Sm did not correlate with or predict a disease flare in contradistinction to other serologic markers of SLE, specifically antibodies to double-stranded DNA and cryoglobulins. Though infrequently detected, antibodies to Sm can help in the management of patients with SLE.

Thirty-four cases of SLE treated during the past seven years (1974-1981) in Taipei Municipal Jen-Ai Hospital are reported and analyzed. Diagnosis of SLE was based on ARA preliminary criteria and Hahn's preliminary criteria. There were 32 females (94.2%) and 2 males (5.8%). The mean age at diagnosis was 28.5 years (range 14-51). Clinical manifestations were as follows: facial erythema 24 cases (70.6%), Raynaud's phenomenon 4 cases (11.4%), oral or nasopharyngeal ulceration 7 cases (20.6%), arthritis without deformity 22 cases (64.7%), proteinuria 21 cases (61.8%), pleural or pericardial effusions 13 cases (38.2%), psychosis or convulsions 9 cases (26.5%), hematological abnormalities 25 cases (73.5%). Laboratory findings were as follows: positive ANA test 33/34 (97.0%), hypocomplementemia 10/13 (76.9%), direct Coombs' test 4/18 (22.2%), indirect Coombs' test 1/13 (7.6%), LE cell 19/34 (55.9%), RA Latex 7/17 (41.7%), polyclonal gammopathy 15/17 (88.2%), anemia 25/34 (73.5%), leukopenia 12/34 (35.3%), thrombocytopenia 10/34 (29.4%). Three cases were complicated by herpes zoster, one by hyperthyroidism, and one by autoimmune thyroiditis. Ten cases died, including 4 renal failure, 2 heart failure, 2 cases of committed suicide and 1 case of CNS involvement.
