  Purpose

Objective:

Report manganese serum levels and mortality in encephalopathic patients.

Patients and participants:

Consecutive patients aged > 18 years, with hepatic encephalopathy and informed consent signed by their families.

Interventions:

Patients' clinical characteristics as well as biochemical tests of renal function, hemoglobin, glucose and albumin levels were obtained as well as a blood sample to analyze manganese levels with a graphite furnace atomic absorption spectrometer.

Hypothesis:

There is a difference in the manganese levels between male and female patients.


Condition
Hepatic Encephalopathy

Study Type: Observational
Study Design: Observational Model: Case-Only
Time Perspective: Prospective
Official Title: Manganese, Possible Factor of Higher Mortality in Women With Encephalopathy

Primary Outcome Measures:
  • Clinical Evolution [ Time Frame: six months ] [ Designated as safety issue: No ]
    Number of participants who died versus those who remained alive after 6 months of follow up since the first entrance at the Emergency Room


Secondary Outcome Measures:
  • Manganese Levels [ Time Frame: Up to six months we followed the recruited patients to determine who were still alive ] [ Designated as safety issue: No ]
    From encephalopathic patients, we took individual blood samples, analyzed in the biochemistry laboratory at the National Institute of Neurology and Neurosurgery, Mexico, City, with a graphite furnace atomic absorption spectrometer, according to the technique reported by Pleban.
