UNLABELLED: Acquired hemophilia refers to the development of a clotting factor deficiency typically, when autoantibodies are produced against coagulation factor and tend to be in the elderly and rare in children.
CASE REPORT: A 12-year-old girl with steroid-resistant nephrosis (SRN) was admitted complaining of pain in her right leg and an ultrasound showed a hematoma in her right calf. The coagulation profile revealed partial thromboplastin time prolongation and high titers (156 BU) of anti-factor VIII inhibitors were observed. Where half of the patients with antifactor VIII inhibitors were associated with underlying disorders, additional tests were performed that rule out secondary causes. This patient with long-standing SRN, who was on a maintenance dose of prednisone for six years, was complicated with acquired hemophilia A (AHA). In different to the last recommendations of AHA treatment, we preferred using cyclosporine; which is considered the initial second-line therapy for children with SRN. Complete remission was achieved of both disorders after a month with no recurrence of nephrosis or bleeding events.
CONCLUSION: To our knowledge, nephrotic syndrome with AHA was reported in only three patients, two cases after remission and one during a relapse but no one were treated with cyclosporine. The authors encountered the first case of cyclosporine treatment for AHA in a patient with SRN. This study supports the use of cyclosporine to treat AHA, especially with nephrosis.
