A critical approach to therapeutic apheresis in the management of inflammatory dysimmune polyneuropathies.

Data concerning 37 patients with inflammatory dysimmune polyneuropathy treated by discontinuous flow centrifugation, membrane plasma separation and cascade filtration are presented. Plasmapheresis was combined with immunosuppressants in patients with chronic or relapsing neuropathy (8 patients), cryoglobulinemic (6 patients) and paraneoplastic disease (2 patients), whereas 21 patients with acute Guillain-Barré syndrome (GBS) underwent exclusively plasmapheresis. Most patients were treated during the onset or progression of their disease and excellent or satisfactory clinical results were obtained in 18 patients with GBS, 6 with cryoglobulinemia, 2 with paraneoplastic disease and 4 with chronic relapsing polyneuropathy. Prior to therapy, 34 patients had high levels of immune complexes (CIC); this level was clearly reduced by plasmapheresis and clinical results correlated well with this removal. 3 patients with chronic dysimmune polyneuropathy, without any evidence of CIC, were completely unaffected by treatment. The possible role of CIC in demyelinating polyneuropathies is discussed on the basis of information given by cascade filtration treatment of 7 patients.

Plasmapheresis combined with lymphocytapheresis and cytotoxic drugs as a therapeutic modality in neuroimmunological diseases.

Rebound after plasmapheresis is thought to be due to enhanced antibody and/or immune complex production. To prevent rebound a combination of steroids and immunosuppressive drugs has been used: lymphocytapheresis was employed in most patients, for not more than 10 sessions. 50 patients with myasthenia gravis, inflammatory myopathy, chronic dysimmune polyneuropathy and immune complex polyneuropathy have been treated and long-lasting benefits obtained in 35 patients. Rebound effects were observed only when cytotoxic drugs were not given or discontinued too soon. 8 patients who had been treated by plasmapheresis combined with steroids alone, after some recurrences of their disease, were switched to cytotoxic drugs, steroids and lymphocytapheresis combined with plasma exchange: in this group 7 patients eventually gained long lasting remissions. Our clinical experience strongly supports the hypothesis of a synergy between plasmapheresis and immuno-suppressive measures.

Encephalomyelitis with thyrotoxicosis.

A case of thyrotoxicosis associated with neuropathy and encephalomyelitis is reported which gradually improved as regards the hyperthyroidism and the neurological deficit during treatment with Tapazole. The possible role of the nervous system of an excess of thyroxine or an autoimmune factor as a cause of the involvement is discussed.

Plasma-exchange in neurological diseases.

This paper summarizes experience with plasma-exchange therapy for neurological diseases at the Saronno hospital. Most treatments were performed by discontinuous flow centrifugation, but membrane plasma separation and cascade filtration were also employed. Eighty-five patients with demyelinating diseases of the peripheral nervous system (Guillain-Barré syndrome, immune complex polyneuropathies, paraneoplastic polyneuropathies), demyelinating diseases of the central nervous system (multiple sclerosis, subacute sclerosing panencephalitis), dermatopolymyositis and myasthenia gravis have been treated so far. Particular attention is paid to the combination of plasmapheresis with lymphocytapheresis and immunosuppressive drugs. This therapeutic approach appears to bring about dramatic and sustained improvement in most patients with neurological diseases, thus altering their natural course.
