Insights
This study found that individuals dependent on ethanol and also smoking heavily had high blood levels of carbonmonoxyhaemoglobin (COHb) and ethanol. These factors contribute to significant health issues in patients undergoing detoxification.
Area of Science:
- Toxicology
- Clinical Biochemistry
- Addiction Medicine
Background:
- Ethanol dependence is often comorbid with cigarette smoking.
- High levels of ethanol and carbonmonoxyhaemoglobin (COHb) are expected in individuals with substance use disorders.
Purpose of the Study:
- To quantify daily cigarette and ethanol consumption in ethanol-dependent individuals.
- To assess blood COHb, ethanol, and acetate levels upon admission to a detoxification clinic.
- To investigate the relationship between substance use and related pathologies.
Main Methods:
- Self-reported daily consumption of cigarettes and ethanol.
- Measurement of blood COHb, ethanol, and acetate concentrations.
- Biochemical and haematological analysis.
- Review of medical history and physical examination.
Main Results:
- Average consumption: 40 cigarettes/day and 320 g ethanol/day.
- Mean blood COHb: 8.5% (men) and 9.9% (women).
- Mean blood ethanol: 220 mg/100 ml (men) and 280 mg/100 ml (women).
- Elevated blood acetate correlated negatively with oxygenhaemoglobin.
- COHb levels decreased by approximately 35% by 0700 h.
- Significant ethanol and/or cigarette-related pathologies were observed.
Conclusions:
- Simultaneous high cigarette abuse must be considered in studies of lipid and lipoprotein metabolism in ethanol-dependent individuals.
- Combined ethanol and tobacco use leads to significant physiological disturbances and health risks.
- Detoxification clinics encounter patients with substantial levels of toxic substances in their blood.
Abstract:
Self-reported daily consumption of cigarettes and ethanol was recorded from a group of 59 ethanol-dependent persons admitted to a detoxification clinic at 2000-2400 h and averaged 40 cigarettes per day and 320 g ethanol per day, respectively. In consequence, concentrations of blood COHb and ethanol were high. Mean values for COHb were 8.5 and 9.9% in men and women, respectively, while the corresponding levels for ethanol were 220 and 280 mg/100 ml. Blood acetate concentrations were also elevated and correlated negatively with mixed venous oxygenhaemoglobin concentrations. The mean carbonmonoxyhaemoglobin concentration at 0700 h was found to be approximately 65% of that on admission. Biochemical and haematological analysis, past medical history and current physical examination revealed a high degree of ethanol and/or cigarette-related pathology. Studies on lipid and lipoprotein metabolism in ethanol-dependent persons should take into account their simultaneous high cigarette abuse.

Types of Hypoxia
There are four primary types of hypoxia, each resulting from a different cause:
1. Anemic hypoxia: This type occurs due to insufficient oxygen delivery caused by a lack of red blood cells (RBCs) or RBCs with abnormal or...
