“…Previous studies in a prospective randomized trial have shown that CY is effective as a second-line therapy for many of those who are steroid-resistant [13], and that successful treatment and long-lasting remission was achieved in SLE patients with acquired FVIII inhibitors [8,11]. On the other hand, CsA, alone or with PSL as salvage therapy or as a first-line treatment, has been shown to be effective for acquired hemophilia [23][24][25][26][27][28][29]. It can be administered to patients who do not respond to standard immunosuppressive regimens and is also effective in patients with underlying SLE [3,6,12], such as in our case.…”
