Diminished blood selenium levels in alcoholics

Area of Science:

• Biochemistry
• Clinical Nutrition
• Toxicology

Background:

• Chronic heavy ethanol ingestion is a global health concern.
• Alcoholism is associated with various nutritional deficiencies.
• Selenium is an essential trace element with antioxidant properties.

Purpose of the Study:

• To investigate selenium levels in plasma, whole blood, and red blood cells of patients with chronic heavy ethanol ingestion.
• To compare selenium levels with those in normal controls.
• To explore the relationship between selenium status and nutritional parameters in alcoholics.

Main Methods:

• Spectrofluorometry was used to determine selenium concentrations.
• 30 patients with chronic heavy ethanol ingestion and 20 healthy controls were included.
• Nutritional status was assessed through various clinical and biochemical markers.

Main Results:

• Significantly lower plasma, whole blood, and red blood cell selenium levels were observed in alcoholics compared to controls (p < 0.0001).
• No significant differences in nutritional parameters like body weight, muscle circumference, albumin, or lymphocyte count were found.
• Elevated liver enzymes in some alcoholics did not correlate with selenium levels.

Conclusions:

• Depressed blood selenium levels are common in chronic heavy ethanol users, irrespective of overt malnutrition.
• Selenium deficiency may play a role in the pathogenesis of alcohol-induced organ injury.
• Further research is needed to elucidate the connection between selenium deficiency and alcohol-related organ damage.
