    Abstract:
    OBJECTIVE: Therapeutic protocol and indication of immunoadsorption therapy (IA) for lupus nephritis (LN) have not been established, although it has been reported to be effective in resistant cases. Here, we performed IA and double filtration plasmapheresis (DFPP) in combination with high-dose methyprednisolone in patients with LN, and studied possible indications of IA. METHODS: IA and DFPP were performed in 9 patients each with LN. They were immediately followed by intravenous infusion of 500 mg of methylprednisolone for prevention of rebound phenomenon. After these treatments 1-2 times a week, a total of 4-6 times, clinical findings were observed for 6 months. RESULTS: The effects on clinical findings such as erythema, fever and arthralgia, serum complement activity, mean urinary protein and reduction of dose of adrenocorticosteroids were comparable in both treatments. Serum titers of ADNA decreased by IA more than DFPP (16% in IA, 38% in DFPP in 3 months), while serum immunoglobulins decreased by IA less than DFPP. Responses in urinary protein after IA tended to be better in patients with high titer of serum ADNA and without nephrotic syndrome, and not associated with disease activity of SLE. CONCLUSION: Removal of ADNA was more selective in IA than in DFPP, and the effects of IA were comparable with those of DFPP. Since patients with low titers of serum ADNA and nephrotic syndrome showed poor responses to IA, it might be worth trying rather in patients with early phase of lupus nephritis.
