It is known that in myasthenia gravis(MG) the plasmapheresis therapy removes the acetylcholine receptor (AChR) antibodies and other toxins in the serum to cause clinical improvement temporarily. To know the effects of plasmapheresis on AChR antibody and clinical courses the authors checked serially the AChR antibody titers and clinical stages in myasthenia gravis. The plasmapheresis were performed for the therapeutic purposes in seven and elective purposes in three MG subjects. After two, three or four cycles of plasmapheresis, the myasthenic symptoms have dramatically improved in all subjects. However the AChR antibody titers decreased in only four out of ten and the decremental ratio in each case uas rather smaller than being expected. Thus the effects of plasmapheresis could not be explained solely by the decreasing phenomena of AChR antibody titers in MG subjects. Therefore the authors assumed that the clinical severities of MG could be correlated with other types of AChR antibodies that are not checked by the routine @-bungarotoxin binding technique, or the AChR antibodies are secondarily produced in large amount by the mechanism of rebound enhancing activity.

The present study was designed to evaluate a beneficial effect of plasmapheresis on Guillain-Barre syndrome comparing wth the combined therapy(plasmapheresis and steroid and/or gamma globulin). Exchange fluid used for plasmapheresis was fresh frozen plasma and the amount of exchanged plasma was 40-50ml/kg in each exchange for 3 to 5 times. Plasmapheresis had been of benefit on Guillain-Barre syndrome. Without serious adverse effect. But there was no difference between the effect of plasmapheresis and the combined therapy.

Immune complexes are found in the circulation of 30%-75% of patients with urticarial vasculitis and much evidence supports the role of these immune complexes in the pathogenesis of urticarial vasculitis. Plasmapheresis is effective for removing these immune complexes; however, there are few reports on the use of plasmapheresis in the treatment of urticarial vasculitis. We describe a case of "refractory" urticarial vasculitis in which the symptoms improved after plasmapheresis treatment. We suggest that plasmapheresis be considered as an option in patients with severe or treatment-resistant urticarial vasculitis.

OBJECTIVETo discuss the effectiveness of severe and acute organophosphate poisoning (AOPP) treated with plasma exchange in China.

METHODSResearches about effectiveness of severe AOPP treated with plasma exchange were analyzed by Review Manager 4.2 and fixed effect model of meta-analysis method were used.

RESULTSSix trials including 433 patients were identified. Treatment group including 211 patients adopted traditional physician therapy plus plasma exchange, and control group including 222 patients received physician therapy only. The case-fatality rate of the treatment group was lower than the control one [RR=0.30, 95%CI (0.19-0.49), P<0.01].

CONCLUSIONPlasma exchange can improve the cure rate of severe AOPP.
