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.

We describe a 58-year old patient with chronic lymphocytic leukemia (CLL) who developed systemic lupus erythematosus (SLE) with severe joint involvement. Dilated myocardiopathy precluded the use of high corticoid doses and a 15 days of prednisone (15mg/d) had no effect on the polyarthritis. Therefore, fludarabine (25mg/m2) was administered for 5 d. One month after the first cycle, fever, muscle stiffness and polyarthritis resolved. A total of 6 cycles were administered. The evolution was complicated by herpes zoster infection and left pneumococcal pneumonia. At this time of writing (July 1999), the patient is symptom free but is profoundly lymphopenic.

Aggressive immunosuppressive therapy with cyclophosphamide has improved the outcome of major organ disease in lupus patients. Controlled trials have shown that pulse cyclophosphamide is the treatment of choice for patients with moderate to severe proliferative nephritis. Long-term follow-up of patients participating in these controlled trials suggests that combining pulse cyclophoshamide with pulse methylprednisolone increases efficacy but not toxicity. Retrospective case series have also shown that pulse cyclophosphamide therapy may be effective for the management of severe or refractory to standard therapy neuropsychiatric, pulmonary, cardiovascular and hematologic disease. Pulse cyclophosphamide is associated with an increased risk for herpes zoster infections in the short term and with sustained amenorrhea in the long-term. Recent studies have also drawn attention to the lack of response (or incomplete response) and flare of lupus after an initial response. In an effort to circumvent these limitations, current investigations explore the therapeutic potential of high-dose, immunoablative cyclophosphamide therapy or low-dose cyclophosphamide in combination with nucleoside analogs or biologic response modifiers.

Cyclophosphamide (CYC) has proven beneficial in preserving renal function in patients with lupus with diffuse proliferative glomerulonephritis (DPGN). However, the optimal route of CYC administration is unknown because direct comparative studies are unavailable. In this open study, we compared the renal outcome of two historical cohorts of patients with diffuse proliferative lupus nephritis (World Health Organization classes IVa and IVb) treated with either intravenous (IV) pulse CYC (group A; n = 22) or sequential oral CYC followed by azathioprine (AZA; group B; n = 21) and followed up prospectively. Both groups of patients had similar clinical, biochemical, and renal parameters at baseline. At 24 months posttreatment, significant improvements in proteinuria, creatinine clearance, serum albumin level, and lupus serological results were evident in both groups. Compared with patients in group A, patients in group B had more complete or partial remission (90% versus 73%) and less risk for treatment failure (5% versus 14%), renal flares (5% versus 14%), and doubling of creatinine levels (5% versus 9%), but the difference was not statistically significant. However, patients treated with oral immunosuppression had an insignificant increase in rates of herpes zoster infection (19% versus 9%) and menstrual disturbance (50% versus 29%). We conclude that sequential oral immunosuppression with CYC and AZA tended to have better efficacy than IV pulse CYC in the treatment of lupus DPGN but was associated with more toxicities. Additional randomized trials involving a larger cohort of patients with a longer period of observation are necessary.

We examined risk factors for systemic lupus erythematosus (SLE) in 265 recently diagnosed patients in North Carolina and South Carolina and 355 control subjects identified through driver's license records and frequency matched to patients by age, sex, and state. Analyses were limited to exposures before diagnosis (cases) or reference year (control subjects). SLE patients were more likely than control subjects to report a history of allergy to medications (odds ratio [OR] 3.1, 95% confidence interval [CI], 2.1-4.5), particularly to antibiotics. SLE risk increased with history of shingles (OR 2.5, 95% CI 1.1-5.9) and with frequent (more than once per year) cold sores in the 3 years before diagnosis (OR 2.8, 95% CI 1.4-5.4). There was little association with history of mononucleosis, a marker of late infection with Epstein-Barr virus, implanted medical devices, or hepatitis B vaccination. History of lupus in parents or siblings was associated with an increased risk (OR 3.3, 95% CI 1.2-8.6). Further research is needed to clarify whether medication allergies and specific infectious agents are involved in the etiology of SLE. Published by Elsevier Science Inc.

Thrombotic thrombocytopenic purpura is a rare but serious condition in childhood. It can be idiopathic or a complication of other diseases or drug therapy. We report on a 12-year-old Chinese girl who presented with fulminant systemic lupus erythematosus with progressive renal failure, pancytopenia, and cerebral dysfunction due to thrombotic thrombocytopenic purpura. The patient also had Pneumocystis carinii pneumonia, Pseudomonas septicaemia, and Herpes zoster infections as a result of immunosuppressive treatment. She responded to combined therapy with pulse methylprednisolone, cyclophosphamide, plasmapheresis, and intensive care support, and completely recovered renal and neurological function. A review of the English-language medical literature since 1968 identified 20 other paediatric cases of systemic lupus erythematosus and thrombotic thrombocytopenic purpura. Clinical features, treatment, and outcome of these cases are presented and discussed. Early recognition is important, and although plasmapheresis is not of proven benefit in severe cases of systemic lupus erythematosus, it is life-saving in lupus-related thrombotic thrombocytopenic purpura and must be instituted early to avoid a poor outcome.

A 61-year-old woman experienced a high fever with anemia and APTT prolongation after suffering a herpes zoster virus infection. Physical examination revealed a large splenomegaly without lymphadenopathy. Laboratory evaluations were positive for lupus anticoagulant (LA) and monoclonal IgM-kappa protein. LA was associated with the presence of anti-beta2GPI antibody, anti-cardiolipin antibody, and anti-prothrombin antibody. Moreover, the results of factors IX, XI, and XII assays and CRP and FDP-E were disturbed. A splenectomy was performed, and a splenic marginal zone lymphoma (SMZL) was diagnosed. All hematological findings rapidly recovered after the splenectomy. No thrombotic events occurred after the splenectomy even though thrombosis prophylaxis was not performed. The clinical course suggested that the SMZL-producing antibody induced immunological abnormalities in the labolatory tests. Since the patient suffered disease progression soon after the splenectomy, an autologous peripheral stem cell transplantation with rituximab administration was performed.

Madarosis may be a presenting feature of a number of vision and life-threatening conditions, including herpes zoster, leprosy, HIV/AIDS, trachoma, malignant eyelid tumors, discoid lupus, scleroderma, and hypothyroidism. It may occur via two broad pathogenic pathways: scarring and non-scarring, which indicates the potential for lash re-growth. Madarosis may occur as an isolated finding or together with loss of other body and scalp hair. The etiology of madarosis can be further divided into dermatological, infection, endocrine, neoplastic, drug-related, congenital, and trauma. This report includes salient points in the clinical history and examination of patients with madarosis, with an emphasis on excluding or diagnosing visual or life threatening disorders associated with madarosis.

Mycophenolate mofetil (MMF) with prednisolone has been associated with high remission rates when used as induction treatment for lupus nephritis. This prospective, multicentre, cohort study investigates the efficacy and safety of this regimen over 24 weeks in 213 Chinese patients with active lupus nephritis (Classes III, IV, V or combination). Baseline activity index (AI) was 6.91+/-3.33 and chronicity index (CI) was 1.9+/-1.2. The remission rate was 82.6% at 24 weeks (complete remission, 34.3%; partial remission, 48.4%). There were significant (P<0.01) improvements in kidney function shown by reductions in proteinuria, serum albumin, serum creatinine and creatinine clearance, as well as in systemic lupus erythematosus disease activity index (SLEDAI) scores. Independent risk factors influencing remission were pathological classification (including Class V and III or Class V and IV nephritis) and elevated serum creatinine at baseline (OR 2.967, 95% CI: 1.479-6.332, P=0.001 and OR 1.007, 95% CI: 1.002-1.011, P=0.001, respectively). Patients with concomitant membranous features on biopsy had a lower remission rate than those with Class III and IV nephritis (66.7% vs 87.3%, P=0.002). Renal biopsy was repeated in 25 patients following treatment. There was a transition to less severe pathological morphologies in majority of subjects. Infections were monitored throughout treatment: eight patients (3.8%) experienced bacterial infections, whereas herpes zoster occurred in seven patients. Nine patients (4.2%) suffered from gastrointestinal upset, which resolved without discontinuation of MMF. One patient became leucopenic, whereas another died from active disease unrelated to kidney symptoms. MMF combined with prednisolone is an effective and well-tolerated induction treatment for patients with active lupus nephritis and for controlling SLE systemic activity.

Patients with lupus membranous nephropathy (LMN) are at substantial long-term risk for morbidity and mortality associated with protracted nephrotic syndrome, including ESRD. The optimal treatment for this condition is controversial. Forty-two patients with LMN participated in a randomized, controlled trial to compare adjunctive immunosuppressive drugs with prednisone alone. Adjunctive regimens included either cyclosporine (CsA) for 11 mo or alternate-month intravenous pulse cyclophosphamide (IVCY) for six doses; the control group received alternate-day prednisone alone. Median proteinuria was 5.4 g/d (range 2.7 to 15.4 g/d). We assessed the primary outcome, time to remission of proteinuria during the 12-mo protocol, by univariate survival analysis. At 1 yr, the cumulative probability of remission was 27% with prednisone, 60% with IVCY, and 83% with CsA. Although both IVCY and CsA were more effective than prednisone in inducing remissions of proteinuria, relapse of nephrotic syndrome occurred significantly more often after completion of CsA than after IVCY. By multivariate survival analysis, treatment with prednisone and high-grade proteinuria (>5 g/d) but not race or ethnicity were independently associated with a decreased probability of remission. Adverse effects during the 12-mo protocol included insulin-requiring diabetes (one with prednisone and two with CsA), pneumonia (one with prednisone and two with CsA), and localized herpes zoster (two with IVCY). In conclusion, regimens containing CsA or IVCY are each more effective than prednisone alone in inducing remission of proteinuria among patients with LMN.
