NZB/NZW F1 female mice were treated with the immunosuppresive enzyme L-asparaginar antibodies, diminished deposition of gamma-globulins in kidneys, significantly delayed the onset of proteinuria, and reduced deaths from nephritis. These effects were associated with reduction of cellular IgM antibody synthesis to both T-dependent and T-independent antigens, but the graft-versus-host reaction was not affected. After several weeks of therapy, antibodies against Asnase appeared in the circulation, the effect on antibody synthesis was lost, ANA and anti-DNA appeared, followed by proteinuria and deaths from nephritis. Therefore Asnase proved to be an effective therapy in NZB/NZW mice, but its usefulness was limited by the appearance of inactivating antibodies.

Twenty-eight patients with SLE and distinct, well-defined renal morphologic lesions of membranous nephropathy were followed up for 4 years. These patients comprised approximately 8% of the patients evaluated for SLE during a 12-year period. The patients with membranous lupus nephropathy had typical systemic features of SLE, and most of them had positive LE cell tests and ANA, low serum complement concentrations, and mildly elevated serum antinative DNA levels. Proteniuria and microscopic hematuria were usually discovered years after systemic symptoms of SLE had developed, Only two patients had slowly progressive renal failure, and most patients continued to have proteinuria. Prednisone treatment did not influence either proteinuria or renal function. In only one patient, the renal character of the disease changed drastically, demonstrating membranoproliferative glomerulonephritis. Six patients died (21%); most of these died of cardiovascular illnesses. The relatively benign and stable renal course of membranous lupus nephropathy in patients with otherwise typical SLE suggests that the renal pathogenesis is different from that of proliferative lupus nephritis.

A 62-year-old white male suffering from plasmacytosis with monoclonal gammopathy developed gastrointestinal bleeding, microscopic hematuria, proteinuria and progressive azotemia. A renal biopsy demonstrated capillary wall thickening, mesangial hyperplasia, crescent formation and subepithelial humps. Serum immunoglobulin analysis showed IgG of lambda type. Serum complement, ANA, ASO titer and cryoglobulin were normal. It is suggested that proliferative glomerulonephritis with subepithelial humps should be added to forms of renal pathology that can be seen in plasma cell dyscrasias.

Dimethylsulfoxide was given to NZB/W F1 female mice from age 10 weeks to see if proteinuria and glomerular injury could be reduced. Twenty mice were randomly assigned to saline or DMSO treatment groups and the following studies were done: urine protein determination, serum concentrations of creatinine, IgG, C3, and albumin; and ANA titers. Kidney tissue were studied by light, immunofluorescent and electron microscopy. DMSO-treated mice had significant reductions in protein excretion at 5 and 6.5 months of age; in urine protein/creatinine ratio at 6.5, 7, and; 7.5 months; in serum C3 at 7.5 months; and in serum creatinine concentration. There were no significant differences among serum IgG, nor among the ANA titers. Histopathologic studies revealed nearly normal kidneys in 5/6 DMSO-treated mice whereas 4/8 controls had severe mixed membranous and membranoproliferative glomerulonephritis. Ultrastructural studies revealed mesangial, subendothelial, and subepithelial deposits and membranous transformation of the glomerular capillary wall. DMSO therefore appears capable of ameliorating glomerular injury in NZB/W F1 mice.

Nine patients who developed proteinuria while on Tiopronin (a D-Penicillamine-like drug) have been studied. Nephrotic syndrome was observed in six cases. Immunologic analysis revealed a high frequency of ANA positivity and RF seronegativity by the time nephropathy appeared. Six patients were biopsied. Immunofluorescence, electron and light microscopy studies showed: glomerulonephritis with segmental deposits in the mesangium and along the capillary walls in one patient, mesangioprolipherative glomerulonephritis in one case and stage 1 membranous glomerulonephritis in four cases. Immunogenetic typing disclosed a strong association with B35-Cw4 class I antigens.

A case of recurrent lupus nephritis in an 18-year-old girl with a renal transplant is described. Serological titer of ANA and Anti-DNA were low prior to renal transplantation following pulse therapy with methylpredonisolone and high dose oral predonisolone. A living related transplantation was performed after 6 months of hemodialysis. Maintenance immunosuppressive therapy consisted of predonisolone, mizoribine and cyclophosphamide. Graft function remained stable for one and half years after transplantation. Clinical recurrence was heralded by the development of proteinuria. If the serologic activities had been analyzed, the increase in ANA and Anti-DNA titers a few months before the onset of proteinuria might have predicted a possible histopathological recurrence. Fortunately, however, despite the histological and clinical recurrence of systemic lupus erythematosus, her renal allograft has continued to function fairly well.

One hundred sixty-two consecutive patients with rheumatoid arthritis (RA) were studied for possible association between HLA antigens, particularly DR antigens, and disease characteristics and adverse reactions to gold or D-penicillamine treatment. The frequency of HLA-DR4 was significantly increased: 62% in RA compared to 23% in controls. An association of HLA-DR4 with a positive family history for RA was also found. HLA-DR4 was not associated with subcutaneous nodules or keratoconjunctivitis, presence of rheumatoid factor, or ANA positivity. No increased prevalence of HLA-DR3 was found in patients who developed drug related toxicity (e.g., proteinuria for gold or D-penicillamine). Of the 27 patients in whom proteinuria developed, only 5 were DR3 positive. A significant association with D-penicillamine induced proteinuria and HLA-B8 gene was found. Our results obtained in a systematic survey do not confirm previous reports of a significant association between HLA-DR3 and drug toxicity, but confirm the association between HLA-DR4 and the development of RA and HLA-B8 and D-penicillamine induced proteinuria.

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.

The coexistence of systemic lupus erythematosus (SLE) and thymoma is rare. We describe 2 female patients with this combination. A 48-year-old woman presented with dyspnea due to a left pleural effusion. Her past history revealed over the previous 3 years the development of anemia, thrombocytopenia, alopecia, pericardial effusion and proteinuria. Four months prior to this hospitalization, the patient was first admitted due to purpura. At that time, laboratory tests revealed an elevated sedimentation rate, elevated titers of ANA and anti-DNA. Chest X-ray demonstrated a widened mediastinum, and upon operation an encapsulated thymoma was excised. Four months following the thymectomy, the patient is unresponsive despite high dose steroid therapy. Another patient, a 30-year-old woman, presented with SLE (cutaneous, arthritis, anemia, positive ANA and high titers of anti-DNA) and thymoma simultaneously. Six years after thymectomy the patient is in SLE remission. Thymectomy in mice prone to autoimmunity (NZB/W mice) has been shown to accelerate the autoimmune manifestations. Conversely, the opposite effect is seen in MRL/lpr mice. The immunological effect of adult thymectomy on the course of human SLE remains to be established, on a larger series of patients. It seems that the heterogenicity of human patients is exemplified by the contrasting effects of thymectomy for thymoma in SLE patients.

A 15-year-old girl had severe Raynaud's phenomenon and arthralgias. A high ANA-IF titer was found and undifferentiated connective tissue disease was diagnosed. After 7 years of moderately flaring disease the patient deteriorated and presented with congestive heart failure, pleuropericardial effusion, hemolytic uremic syndrome, proteinuria and moderate hypertension. Autoantibodies against DNA, Sm-protein, and very high titers against U1RNP were detected. Therapy with high steroid doses, a cyclophosphamide pulse and 4 weeks of plasmaphresis with plasma exchange improved the heart, but not the renal condition. Symptomatic pancreatitis became the dominant problem of a progressively consuming process that resulted in the death of the patient. Post-mortem examination revealed widespread vasculopathy with intima proliferation and only minimal fibrosis involving the kidneys, heart and other main organs, including the pancreas. Taken together, the clinical picture was of an overlap between scleroderma and systemic lupus erythemathosus; the serologic and histopathologic findings suggest a diagnosis of a severe form of mixed connective tissue disease (MCTD).
