title: [Acid-base disturbances in hematologic diseases].
abstract: In this article, the acid-base disturbances encountered in hematologic diseases are discussed. Occurrence of lactic acidosis (LA) without obvious clinical tissue hypoxia has been reported in patients with leukemia and lymphoma. Most of the patients with LA had liver involvement and clinical evidence of impaired hepatic function, suggesting that both increased production and decreased lactate metabolism are necessary for the development of LA in leukemia and lymphoma. Acute tumor lysis syndrome consists of hyperuricemia, hyperpotassemia, and hyperphosphatemia with hypocalcemia following neoplastic cell lysis, particularly in lymphoproliferative disorders. In patients with multiple myeloma (MM), proximal renal tubular acidosis (Fanconi syndrome) associated with Bence Jones proteinuria has been reported. In addition, MM is one of the first conditions recognized to be associated with lower anion gap.
