Introduction
Although chronic alcohol consumption has progressively decreased in recent years, a third of people over 15 years declare at least one episode of excessive use every month, which ranks Romania on second position, with a rate of 35%, far above the average registered in the EU (20%). Therefore, Romania has one of the highest incidence rates of alcohol-related liver cirrhosis, which has become a major public health problem. This study aimed to investigate the prevalence of liver fibrosis in the asymptomatic alcohol-consuming population.
Aims & Methods
The study aimed to evaluate the relationship between advanced liver fibrosis measured by transient elastography, laboratory parameters, and the amount of alcohol consumed depending on non-modifiable risk factors such as age and gender. Between January 2022 and December 2022, we examined patients with day hospitalization in the Institute of Gastroenterology and Hepatology in Iasi, without liver history, who admitted a moderate or high consumption (women <7 versus >7 drinks/week; men <14 versus >14 drinks/week) for at least one year. The classification of the fibrosis stage by transient elastography was adjusted according to transaminase values. The results were analyzed by univariate analysis and logistic regression to establish models of prediction.
Results
The study included 689 patients with an average age of 49.32±14.31 years, a proportion of 63.7% represented by men. Advanced fibrosis (³ F3) was detected in 19.30% of the examined patients, predominantly in men (14.1%) and patients over 55 years old (12.5%). Excessive alcohol consumption is associated 2 times more with advanced fibrosis in women (OR=5.08; CI 95%: 3.45-9.50, p<0,001) and the group under 40 years old (OR=6.29; CI 95%: 1.67-9.43, p<0,001) compared to men (OR=2.27; CI 95%: 1.76-3.81, p=0,012) respectively patients over 55 years old (OR=3.21; CI 95% : 2.28-4.45 p<0,001). Using logistic regression, it was demonstrated that there was a strong correlation between advanced fibrosis, excessive alcohol consumption, low serum albumin level and the reduction of triglycerides in men (R2 Nagelkerke = 0.854; p<0.001) supplemented with the reduction of cholesterol in the age group 40-55 years (R2 Nagelkerke = 0.785; p<0.001), respectively of ferritin in those over 55 years old (R2 Nagelkerke = 0.804; p<0.001). The association of excessive alcohol consumption, age, low levels of albumin, LDL-cholesterol and C-reactive protein generated a significant predictive model (R2 Nagelkerke = 0.784; p<0.001) for female patients.
Conclusion
Screening using transient elastography represents an approach that could provide early diagnosis of advanced liver fibrosis in an asymptomatic population, with the possibility to prevent the evolution of ALD and the development of complications of cirrhosis.
