Evaluation of methaemalbumin in acute pancreatitis.

Methaemalbumin (MHA) was measured in 62 patients with acute pancreatitis. In 26 MHA-positive patients the occurrence of renal and pulmonary complications was 65% and 58%, respectively, compared with 3% and 6% in 36 MHA-negative patients. Fatality rate was 54% in MHA-positive and 6% in MHA-negative patients. In 17 MHA-positive cases haemorrhagic pancreatitis was proven at laparotomy or postmortem examination. Thus MHA determination proved to be a valuable diagnostic and prognostic parameter in acute pancreatitis.
