Multicentric Castleman's Disease (MCD) is an atypical lymphoproliferative disorder, related to human herpesvirus 8 (HHV-8) infection and often associated with autoimmune diseases such as haemolytic anaemia and thrombocytopenia.

Lymph node histology revealed MCD, while the screening for the bleeding disorder showed prolonged activated partial thromboplastin time (APTT) (ratio: 1.89, normal value <1.24), low factor VIII (FVIII:C) levels (6%) with anti-factor VIII antibodies (2.3 Bethesda units), leading to a diagnosis of AH.

Abstract

Multicentric Castleman's Disease (MCD) is an atypical lymphoproliferative disorder, related to human herpesvirus 8 (HHV-8) infection and often associated with autoimmune diseases such as haemolytic anaemia and thrombocytopenia. Acquired haemophilia (AH) is a rare, life-threatening disease, which can occur in association with lymphoproliferative disorders, although only one case of AH in MCD has been described so far. We report the case of a human immuno deficiency virus negative 71-yr-old woman referred to our hospital for prolonged bleeding on surgical site following a lymph node biopsy. Lymph node histology revealed MCD, while the screening for the bleeding disorder showed prolonged activated partial thromboplastin time (APTT) (ratio: 1.89, normal value <1.24), low factor VIII (FVIII:C) levels (6%) with anti-factor VIII antibodies (2.3 Bethesda units), leading to a diagnosis of AH. Virological studies on plasma, lymphocyte and bronchoalveolar wash showed positivity for HHV-8 infection. Treatment with steroids (metilprednisolone 1-1.5 mg/kg/d) and cyclophosphamide (100 mg/d orally) was unsuccessful, and then antiviral therapy with cidofovir (5 mg/kg/wk) was started. A transient normalisation of APTT was seen after two administrations of cidofovir, but then coagulation parameters worsened and a large haematoma of the arm appeared. Bleeding was successfully stopped with two boluses of recombinant activated factor VII (Novoseven 90 microg/kg). Therapy with anti-CD 20 monoclonal antibody rituximab (Mabthera 375 mg/m2 once a week for 4 wk) was started, and following two administrations APTT normalised once again. Cardiological and neurological complications arose before the third dose of rituximab and the patient died shortly afterwards.
