A rare SLE patient with central nervous system involvement (CNS-SLE) who relapsed presenting new symptoms associated with the development of serum anti-Sm antibody and was then successfully treated with cyclophosphamide (CY) pulse therapy is presented here. A 47-years old housewife was admitted to Kushiro City General Hospital because of fever, limb erythema and drowsy consciousness in September 1995. On the basis of convulsion, proteinuria, leukopenia, thrombopenia, serum positive tests for both anti-nuclear antibody and anti-SSA antibody and low complement levels, as well as elevations of IgG index and IL-6 in the cerebrospinal fluid (CSF), she was diagnosed as having CNS-SLE. Serum tests for anti CL-beta 2 GPI antibody and lupus anticoaglant was negative. Serum test for HBs antigen was positive. She was treated successfully with methylprednisolone (mPSL) pulse therapy and plasma exchange (PE). Prednisolone was gradually tapered to the dosage of 17.5 mg per day and she was discharged in April 1996. She was re-admitted because of fever, an exacerbation of skin eruption and arthralgia in October 1996. Serum anti-Sm antibody was found to be positive. mPSL pulse therapy was not effective. On the basis of hallucination and elevations of IgG index and IL-6 in the CSF, a diagnosis of relapsed CNS-SLE was made. However the level of IFN-alpha in the CSF was normal. Although PE was not effective, CY pulse therapy was markedly effective.

Controlled clinical trials in renal transplantation have demonstrated that mycophenolate mofetil is well tolerated and has lower renal transplant rejection rates than azathioprine regimens. This study reports on the clinical experiences at two institutions with mycophenolate mofetil (MMF) for severe lupus nephritis. Twelve patients with relapsing or resistant nephritis previously treated with cyclophosphamide therapy and one patient who refused cyclophosphamide as initial therapy for diffuse proliferative nephritis but accepted MMF were included. During combined MMF/prednisone therapy, serum creatinine values remained normal or declined from elevated values: mean change in serum creatinine was -0.26+/-0.46 microM/L, P = 0.039. Proteinuria significantly decreased: mean change in urine protein-to-creatinine ratios was -2.53+/-3.76, P = 0.039. Decreased serum complement component C3 and elevated anti-double-stranded DNA antibody levels at baseline improved in some, but not all, patients. The mean initial dose of MMF was 0.92 g/d (range, 0.5 to 2 g/d). The mean duration of therapy was 12.9 mo (range, 3 to 24 mo). Adverse events included herpes simplex stomatitis associated with severe leukopenia (n = 1), asymptomatic leukopenia (n = 2), nausea/ diarrhea (n = 2), thinning of scalp hair (n = 1), pancreatitis (n = 1), and pneumonia without leukopenia (n = 1). Recurrence of the pancreatitis led to discontinuation of MMF in this patient; all other adverse events resolved with dose reduction. It is concluded that MMF is well tolerated and has possible efficacy in controlling major renal manifestations of systemic lupus erythematosus. Controlled clinical trials are needed to define the role of MMF in the management of lupus nephritis.

We report a rare case with multiple renal infarction associated with lupus anticoagulant and SLE. A 20-year old woman presented with remitent fever, butterfly rash and, abdominal pain. Laboratory findings showed leukopenia, positive antinuclear and anti-DNA antibodies, and biological false positive for syphilis. Despite a therapy with prednisolone 25 mg/day, the patient showed hypocomplementemia, high titer of anti-DNA antibody and a development of proteinuria and an elevation of serum creatinine. Renal biopsy revealed no abnormalities. She presented abdominal pain with an elevation of serum LDH. Abdominal dynamic computed tomography demonstrated multiple perfusion defects in both kidneys indicating multiple renal infarction. Brain MRI showed multiple micro infarction in the anterior lobes. She was treated with 80 mg of aspirin and have been in remission for two years. Although there have been reported 18 cases with renal infarction associated with antiphospholipid syndrome, this is the first report in Japan. Renal infarction should be differentiated from renal involvement in patients with SLE who have antiphospholipid antibodies.

A 22-year-old woman began to have the symptoms of anorexia, high fever, cough and general fatigue from June of 1997. She was admitted in our hospital on Aug. 8th, 1997 for the further detail examination because of pancytopenia and positive antinuclear antibody (ANA). Her laboratory findings and clinical symptoms were compatible with systemic lupus erythematosus (SLE) such as leukopenia, proteinuria, hypocomplementemia, positive ANA, elevated titer of autoantibodies including anti-DNA, anti-Sm, anti-RNP antibodies, polyarthralgia and photosensitivity. The administration of oral prednisolone (40 mg/day) was started on Aug. 15th, 1997 under the diagnosis of SLE. However, she had severe abdominal pain in epigastrium with elevated serum amylase, ascites and dull shape of pancreas tail by CT scan compatible with acute pancreatitis. On Aug. 18th, her general condition was worsening with fever, epigastralgia, abdominal distension, anemia, weak palpation of radial artery, hypotension, tachycardia, shallow breathing and cold sensation on both extremities as shock. In spite of steroid pulse therapy with nafamostat mesilate intraarterial infusion, her condition was not improved. The dose of 50 mg/day of cyclophosphamide was added to the regimen on Aug. 22nd. Then, gradually her condition started to be restored. Anemia, leukopenia, hypocomplementemia continued. Second steroid pulse therapy was done on Sep. 5th. After then, she became better in her clinical symptoms and laboratory data. The dose of PSL was tapered to 15 mg/day and 7.5 mg/day update of Oct. 1998 without the pseudcysts found after pancreatitis. She is a rare case who recovered from severe acute pancreatitis due to SLE itself.

The present study was undertaken to investigate whether active induction of systemic lupus erythematosus (SLE) in non-obese diabetic (NOD) mice could affect their development of insulin-dependent diabetes mellitus (IDDM). NOD mice were immunized with a human IgM mAb carrying the 16/6 idiotype (MIV-7) or with control human IgM. The mice were bled monthly and tested for SLE-associated autoantibodies in the serum and for the presence of leukopenia, thrombocytopenia, proteinuria and immunoglobulin deposits in the kidneys. The development of diabetes was determined by a blood glucose level exceeding 15 mM on two consecutive weekly determinations and by the presence of insulitis in the pancreas. The NOD mice immunized with MIV-7 developed high and persistent levels of autoantibodies, including anti-DNA, anti-histones and anti-cardiolipin, untreated mice and those immunized with normal human IgM did not produce these autoantibodies. The MIV-7-immunized mice also manifested an elevated erythrocyte sedimentation rate, leukopenia, thrombocytopenia and significant proteinuria, as well as deposits of Ig in their kidney glomeruli. Thus, NOD mice immunized with MIV-7 developed both autoantibodies and clinical features of SLE. The MIV-7-treated mice, however, showed a significantly lower incidence of IDDM (25%vs. 90%, P<0.003), accompanied by amelioration of the insulitis. The present study indicates that the induction of SLE by idiotypic immunization can protect NOD mice from developing IDDM, pointing to the importance of immune dysregulation in shift from one autoimmune disease to another.

Successful maintenance therapy with mycophenolate mofetil (MMF) 2 g/d and low-dose oral corticosteroids (OCS) over a period of 15 mo was given to patients with Wegener's granulomatosis (WG) (n = 9) and microscopic polyangiitis (MPA) (n = 2). All patients had severe generalized disease with pauci-immune necrotizing glomerulonephritis and received standard induction therapy with oral cyclophosphamide and OCS for a mean of 14 wk until remission was achieved. Of 11 patients, only one WG patient relapsed in the 14th month of maintenance therapy. Maintenance therapy with MMF was able to further reduce grumbling disease activity as measured by the Birmingham vasculitis activity score (BVAS2) and proteinuria that were still present by the end of induction therapy. OCS could be reduced to a median daily dose of 5 mg and discontinued in three patients. Possible drug-related adverse effects were transient and included abdominal pain, respiratory infection, diarrhea, leukopenia, and a cytomegalovirus-colitis in one patient that was successfully treated with ganciclovir. It is concluded that MMF in combination with low-dose OCS is well tolerated and effective for maintenance therapy of WG and MPA. Long-term treatment with MMF in these diseases is attractive because of its low toxicity. MMF will have to be studied further and compared with cyclophosphamide or azathioprine maintenance therapy in randomized trials.

The optimal therapy for pure membranous lupus nephritis (MLN) with nephrotic syndrome remains controversial. While the risk of progressive renal deterioration may be small, persistent heavy proteinuria leads to the complications of oedema, hypoalbuminaemia, hyperlipidaemia, hypercoagulability, and venous thrombosis. We examined prospectively the efficacy and tolerability of a sequential immunosuppressive regimen in a cohort of 20 patients with nephrotic syndrome due to pure MLN (WHO Class Va and Vb). Initial therapy comprised prednisolone (0.8 mg/kg/d p.o.) and cyclophosphamide (2-2. 5 mg/kg/d p.o.). Prednisolone dosage was gradually tapered to 10 mg/d at 6 months, when cyclophosphamide was replaced by azathioprine (2 mg/kg/d p.o.) as maintenance therapy. Within 12 months of therapy 11(55%) patients had complete remission (CR), 7(35%) patients achieved partial remission (PR) (proteinuria reduced from 6.2+/-4.0 to 2.0+/-1.7 g/24 h, P<0.01), and 2 patients failed to respond. Improvements in proteinuria and serum albumin level were observed after 3-6 months of treatment. Non-responders had lower baseline serum albumin compared to complete responders. Renal function remained stable during follow-up for 73.5+/-48.9 months. 8 patients had disease relapse at 47+/-15 months. Early complications (</=12 months) included herpes zoster (40%), minor respiratory or urinary tract infections (25%), mild leukopenia (15%), and transient amenorrhea (14.3%). 4 of the 20 patients developed pulmonary tuberculosis during follow-up, at 35+/-24 months after the diagnosis of MLN. 8 patients had hyperlipidaemia. Haemorrhagic cystitis, permanent amenorrhea, vascular complications, and mortality were not observed. We conclude that this sequential immunosuppressive regimen is effective in 90% of patients with MLN and heavy proteinuria. Prudent consideration of the benefits and potential side-effects is required to determine the optimal management for individual patients.

Peptides based on the complementarity-determining region 1 (CDR1) and CDR3 of an anti-DNA monoclonal antibody (mAb) carrying the 16/6 idiotype (Id) were shown to induce experimental systemic lupus erythematosus (SLE) in susceptible mouse strains. In the present study, T-cell lines specific to the pCDR1 and pCDR3 peptides were established in BALB/c and in SJL mice, respectively. The T-cell lines were characterized and analysed for their pathogenicity upon administration to syngeneic mouse strains. Both T-cell lines expressed the alphabeta T-cell receptor (TCR) and the CD4+ CD8- phenotype. Additionally, both cell lines secreted interleukin (IL)-4 and IL-10 upon stimulation with their specific peptide, thus belonged to the T helper 2 (Th2) subset. Upon immunization, the pCDR3-specific T-cell line induced experimental SLE in SJL mice. The animals produced high levels of autoimmune anti-DNA and antinuclear protein antibodies, as well as anti-16/6 Id antibodies (Abs). Furthermore, the mice developed clinical manifestations, including leukopenia, proteinuria and accumulation of immune complex deposits in their kidneys. The pCDR1-specific T-cell line failed to induce SLE when injected into BALB/c mice. It is thus suggested that pCDR3 is an immunodominant epitope in experimental SLE and that pCDR3-specific T cells initiate autoimmunity, leading to SLE, probably via epitope spreading.

The use of intravenous immunoglobulin (IVIg) has been reported as an immunomodulating agent in several autoimmune diseases, including systemic lupus erythematosus (SLE). Herein we report a SLE patient with severe clinical presentation that included pericarditis, pleural effusion, nephrotic range proteinuria, leukopenia, and lymphopenia. The patient received one course of high-dose IVIg (2.8 g/kg body weight), and within a week of post-IVIg therapy, her condition significantly improved. One-month post-IVIg there were decreased proteinuria, elevated leukocytes and lymphocytes count, decrease in antinuclear and anti-dsDNA antibodies, and disappearance of pericarditis and pleuritis. This case demonstrates the efficacy of IVIg in severe SLE with various clinical manifestations.

A peptide based on complementarity-determining region (CDR)-1 of a monoclonal murine anti-DNA Ab that bears the common idiotype, 16/6Id, was synthesized and characterized. The peptide, designated pCDR1, was found to be an immunodominant T-cell epitope in BALB/c mice. The CDR1-based peptide was shown to be capable of inhibiting the in vivo priming of BALB/c mice immunized with the peptide or with the whole anti-DNA 16/6Id(+) mAbs of either mouse or human origin. We show here that administration of pCDR1 (weekly, i.v., 100 microgram/mouse) in aqueous solution for 5 weeks starting at the time of disease induction with the human 16/6Id prevented the development of clinical manifestations of experimental systemic lupus erythematosus (SLE). Further, 10 weekly injections of pCDR1 to BALB/c mice with an established experimental SLE down-regulated clinical manifestations of SLE (e.g., anti-DNA auto-Abs, leukopenia, proteinuria, immune complex deposits in the kidneys) in the treated mice. Prevention of SLE induction was shown to be associated mainly with a decrease in the levels of IL-2, INFgamma, and the proinflammatory cytokine TNFalpha. On the other hand, the secretion of the immunosuppressive cytokine TGFbeta was elevated. Amelioration of the clinical manifestations of an already established experimental SLE correlated with a dramatic decrease in TNFalpha secretion, elevated levels of TGFbeta, and immunomodulation of the Th1 and Th2 type cytokines to levels close to those observed in healthy mice.
