摘要
Project: Hepatic encephalopathy is an increasingly common disease. Identification of prognosis risk factors in patients with liver damage may lead to preventive actions, towards decreasing its mortality. Manganese (Mn) levels are increased in basal ganglia of patients with hepatic encephalopathy as well as in cases of cirrhotic and liver failure patients. The present is a clinical, prospective, prolective and observational study developed at the Internal Medicine Service from "Dr. Dario Fernandez Fierro" General Hospital, ISSSTE, Mexico City. The objective of this work was to report whole blood Mn levels and mortality in encephalopathic patients.
Procedure: Consecutive patients over 18 years of age, diagnosed with hepatic encephalopathy were recruited at the emergency room service. An informed consent, signed by their families was collected. Patients' clinical characteristics, biochemical tests of renal function, hemoglobin, glucose, bilirubins and albumin levels were obtained along with a blood sample to analyze Mn. Patients evolution was followed up for 6 months.
Results: Blood Mn in patients [median, (range)] [20.5, (10.5-39.5) mu g/L] were higher than blood levels from a group of healthy volunteers [7.5, (6.1-12.8) mu g/L] (P < 0.001). Among 9 patients studied four died, 2 women and 2 men, those patients showed higher (P = 0.032) Mn levels [28, (17-39.5) mu g/L] than those alive [13.5, (10.5-32) mu g/L] after the follow up period.
Conclusions: In this pilot study, Mn blood levels were higher in hepatic encephalopathy that died as consequence of the disease that those that survived in a 6 month follow up period. Blood Mn could be a potential prognosis factor for death in patients with hepatic encephalopathy.
