Successful management of polyneuropathy associated with IgM gammopathy of undetermined significance with antibody-based immunoadsorption.

Peripheral polyneuropathies associated with monoclonal IgM gammopathy of undetermined significance often have a progressive course and optimal treatment has not been established. We report on a patient diagnosed with polyneuropathy associated with benign IgM gammopathy, who was successfully treated with antibody-based immunoadsorption only. The neurological symptoms of the patient improved continuously over six months of treatment. Controlled trials should be performed to define this indication for antibody-based immunoadsorption therapy.

Extracorporeal antibody elimination in neuroimmunological diseases.

Extracorporeal procedures for the elimination of autoantibodies are an important therapeutic option in various neuroimmunological diseases, especially those with neuromuscular involvement. Recent advances with the development of selective apheresis methods have given extracorporeal therapeutic procedures a new perspective. In this article, we review the therapeutic use of plasma exchange and immunoadsorption therapy in different neuroimmunological diseases.

Dissociation between high anti-PR3 titers (c-ANCA) and the clinical course of disease in a case of Wegener granulomatosis.

In May 1984 a 58-year-old woman presented with a broad spectrum of clinical symptoms including malaise, arthralgia, hemoptysis and dyspnea, proteinuria and hematuria and a vasculitic necrotizing rash. Bronchial biopsies revealed subglottic granulomatous lesions and renal biopsies showed necrosis, extracapillary proliferation and crest formation, confirming the diagnosis of Wegener granulomatosis. Positive c-ANCA and anti-proteinase 3 subfraction (anti-PR3) titers were first analysed in 1991. Clinical remission was achieved by standard immunosuppressive therapy and renal function was stabilised. Several minor relapses were treated with pulsed intravenous cyclophosphamide but the symptoms could not be completely controlled. Eight years after the onset of disease, a dramatic increase in anti-PR3 titers was observed (34438 U/ml, normal range < 10, ELISA), followed 3 months later by a clinically apparent relapse. Immunosuppressive therapy was reinstituted without clinical improvement. At this point plasmapheresis resulted in an amelioration of clinical symptoms as well as a reduction in anti-PR3 titers. Concomitant immunosuppressive therapy was administered with oral corticosteroids. Forty days later anti-PR3 titers increased, reaching 75000 U/ml twelve months later, however this time without associated clinical symptoms. During the following months the patient had a further transient deterioration of pulmonary and renal function due to secondary bacterial infection which was successfully treated with antibiotics. A nephritic sediment was not present during these episodes. Curiously, the anti-PR3 titers have remained excessively elevated for the last three years.

Effects of hemodialysis on circulating adrenomedullin concentrations in patients with end-stage renal disease.

To characterize the determinants of circulating levels of adrenomedullin (AM), the plasma levels of this peptide were measured in 58 patients with end-stage renal disease on hemodialysis. Predialysis plasma levels of AM were more than twice as high in patients on hemodialysis as compared to controls. In hemodialysis patients with heart failure (NYHA classes II-IV) or hypertensive HD patients plasma levels of AM were significantly higher than in patients with end-stage renal disease only. Plasma levels of AM were not altered immediately by hemodialysis but decreased significantly 14-20 h after hemodialysis. AM plasma levels before hemodialysis and 14-20 h after hemodialysis were correlated with the corresponding mean arterial pressure.
