Waldenstrom's macrogloblinaemia: modified plasmapheresis as treatment option in a Nigeria setting.

We describe a case of Waldenströms macroglobulinaemia in a 56 year old Negroid male, to whom modified plasmapheresis/plasma exchange was offered with good control of symptomatic hyperviscosity Amelioration of the clinical status and objective assessment of response was evident by dramatic reduction in monoclonal immunoglobulins M (IgM) from 100g/L to 14.7 g/L and a fall in erythrocyte sedimentation rate from 130 mm/hr to 80 mm/hr with this therapy. This highlights the need to adopt a modification of manual plasmapheresis in the treatment of the hyperviscosity syndrome complicating this B-cell disease in this environment.
