Multiple myeloma with high adenosine deaminase expression

A 50-year-old man with immunoglobulin A type multiple myeloma (MM) was referred to our hospital after bortezomib therapy. He had high alkaline phosphatase and lactate dehydrogenase levels. Computed tomography showed osteolytic and osteoblastic bone lesions. Response to salvage chemotherapy was temporary, and he developed a right pleural effusion with high adenosine deaminase (ADA) levels. He died from bleeding associated with a pelvic bone fracture 9 months later. ADA mRNA expression and ADA secretion of the MM cells from the patient were higher than those from myeloma cell lines tested. Clinical relevance of high ADA expression in MM cells is warranted
