The objective of the paper was compare the effects and tolerability of combined therapy of multiple intravenous infusions of anti-tumour necrosis factor-alfa (TNF-alfa) monoclonal antibody (Remicade) with methotrexate versus treatment with sodium aurothiomalate and intramuscular depot methylprednisolone in rheumatoid arthritis (RA). We investigate also the interval necessary to obtain the improvement in both treatment groups. 36 patients commencing intramuscular sodium aurothiomalate therapy with intramuscular depot methylprednisolone acetate at weeks 0, 4, 8 and 12 in addition to chrysotherapy were compared in retrospective analysis with 32 patients starting with multiple intravenous infusions of infliximab, anti-TNF-alfa monoclonal antibody (Remicade) and methotrexate at a stable dose. Patients were assessed by composite clinical score (DAS 28) and C-reactive protein during 22 weeks of therapy. At week 2 and 6 a significantly greater percentage of infliximab-treated than gold-treated RA patients achieved improvement in each clinical measurement of disease activity. At 22 week of treatment moderate and good response according to EULAR criteria was achieved in 91% of infliximab-treated patients and 58% gold treated patients (p < 0.001). Adverse events were more frequently observed in infliximab-treated patients, but only gold-treated patients discontinued treatment because adverse events (2 patients due to proteinuria, 2 patients due to mucocutaneous changes and one patient due to leucopenia). The higher percentage of adverse events in infliximab-treated patients was caused mainly by the occurrence of infusion reactions (23 reactions out of 160 infusions); most of them were mild (somnolentia and headache) and transient. Viral infections (including herpes simplex and zoster) were more common in patients treated with infliximab and methotrexate. Combination therapy of infliximab and methotrexate is more effective in reducing clinical and biochemical disease activity than gold with methylprednisolone treatment in RA patients during 22 weeks of treatment, especially in the first 6 weeks.

Wegener's granulomatosis is a systemic necrotising vasculitis of small vessels that leads to severe impairment of affected organ systems. Conventional treatment is based on immunosuppression with a combination of steroids, cyclophosphamide, azathioprine or methotrexate over a prolonged time course. Early recurrence or disease refractory to therapy often results in a fatal outcome. As in other inflammatory disorders, tumor necrosis factor (TNF) plays an early and crucial role in progression of disease activity. We report on a patient with severe orbital Wegener's granulomatosis who developed acute renal failure despite intense conventional immunosuppression with cyclophosphamide and steroids. To stop vasculitic activity, by disrupting the autoimmune inflammatory cascade, a TNF-blocking antibody (Infliximab) was administered six times in a six-month period at 3 mg/kg body weight. Conventional immunosuppressive therapy with steroids and cyclophosphamide was continued, the latter being changed to azathioprine after three months. The first infusion of TNF antibody induced improvement of renal function, which continued throughout the course of therapy. The modification of diet in renal disease-glomerular filtration rate (MDRD-GFR) increased from 15.3 ml/min/1.73 m2 before the start of TNF-blockade to 55.5 ml/min/1.73 m2 after six months of therapy. Serum creatinine levels, proteinuria and cANCA titer decreased concomitantly. Clinical remission of Wegener's granulomatosis was induced without any major adverse events. A slight flare of orbital inflammation was successfully treated with an increased dose of azathioprine. Thus, in this case of refractory Wegener's granulomatosis TNF-blockade by monoclonal chimeric TNF-antibody (Infliximab) served as an effective tool to rescue kidney function and induce clinical remission.

We report a 13-year-old boy with refractory nephrotic syndrome (minimal change with mesangial proliferation) who failed the standard treatment protocols. There was some temporary response to large steroid doses, but even the Mendoza protocol could not induce remission. We show suppression of the proteinuria with Infliximab (Remicade) with tapering of steroids. Serial serum levels of tumor necrosis factor (TNF)-alpha are shown and discussed. We suggest studying the TNF-alpha blocking agents as optional treatment for nephrotic syndrome.

Adult onset Still's Disease (ASD) is a systemic inflammatory disorder of unknown etiology characterized by chronic and fluctuant fever with accompanying rash, polyarthritis and involvement of multiple organs, especially lymphoid tissues. Although kidney involvement may appear in some cases of adult Still's disease, membranous glomerulonephyritis has not been described before. We herein report a 38-year-old man diagnosed with Still's disease with longstanding polyarthritis unresponsive to high-dose steroids and various immunosuppressive drugs for 5 years. He was referred to our clinic with bilateral pretibial edema on his legs. Urine examination revealed 10.5 g/day proteinuria with membranous glomerulonephritis and his renal biopsy came up with it. Infliximab was initiated, and his complaints were totally resolved also with a normal urine test in the following 3 months. To the best of our knowledge, this is the first report that clearly shows the efficacy of infliximab in a patient with refractory ASD with membranous glomerulonephyritis.

Rheumatoid arthritis (RA) is accompanied by a variety of nephropathies. It is often difficult to distinguish between disease-associated and drug-associated renal diseases. Three hundred and seventy-six RA patients with renal involvement were included in our study; they were subjected to full history and clinical examination, kidney function, 24-h urinary protein, and kidney biopsy. All our patients were on methotrexate, low dose steroids, and nonsteroidal anti-inflammatory drugs, in addition to the previous medications. About 79.3%, 20.7%, 6.9%, and 5.9% of our patients were on leflunomide, hydroxychloroquine, etanercept, and infliximab, respectively. Renal presentation was in the form of nephrotic syndrome (33.5%), persistent subnephrotic proteinuria (12.2%), persistent proteinuria and recurrent hematuria (13.3%), acute nephritis (23.9), recurrent hematuria (7.4%), and creatinine >1.5 mg/dL (10.6%). Renal biopsies were glomerular amyloidosis (28.1%), mesangioproliferative (19.1%), membranous (6.1%), crescent (16.8%), focal segmental glomerulosclerosis (18.6%), and minimal changes (11.7%). There was a statistically significant difference in the incidence of membranous nephritis between patients who took leflunomide, and hydroxychloroquine and those did not. Etanercept in our study seems not to be related to any form of renal involvement, while infliximab is related to focal segmental sclerosis and amyloidosis of tubulointerstitial type. Kidney involvement in RA is not a rare complication. Any type of histopathological changes can be present, with amyloidosis on top of the list. Hydroxychloroquine and leflunomide are accused in membranous nephropathy. Infliximab is associated with focal segmental sclerosis and amyloidosis of tubulointerstial type, and etanercept appear to be safe as regards kidney affection.
