Estimation of the prevalence of obstructive sleep apnea in non alcoholic fatty liver disease.

Introduction: The prevalence of non alcoholic fatty liver disease is increasing in parallel with the epidemic of obesity and metabolic syndrome. Recent data have shown frequent association between non alcoholic fatty liver disease (NAFLD) and obstructive sleep apnea.

Aim: To estimate the prevalence of sleep disorders, to search an obstructive sleep apnea syndrome by conducting a ventilator polygraphy and to search the particularities of obstructive sleep apnea when its exists, in patients with NAFLD.

Cardiovascular risk estimation in non alcoholic fatty liver disease.

Background: Nonalcoholic fatty liver disease is rising to the growing epidemic of metabolic syndrome. Recent data suggest that this liver disease may represent a real marker of cardiovascular risk. The aim of our study was to calculate cardiovascular risk and to estimate the frequency of subclinical coronary artery disease by conducting an exercise testing.

Hyponatremia in cirrhosis: Risk factors and prognostic value.

Background Hyponatremia is the most common electrolyte abnormality encountered in cirrhotic patients. Recent studies have shown that hyponatremia was correlated with severity of cirrhosis and associated with increased risk of complications and mortality. However this relationship is still unclear.

Hepatic sarcoidosis: a case series.

Sarcoidosis is a systemic non caseous granulomas disease. Liver is a common location but usually asymptomatic. Evidence based guidelines for this location treatment is lacking and the effect of corticosteroids may be inadequate.

Does protein energy malnutrition affect the outcome in Tunisian cirrhotic patients?

Background: Malnutrition is commonly seen in cirrhotic patients and has been shown to adversely affect outcome. However, it remains associated with the severity of cirrhosis. Therefore, its role as an independent prognostic factor is still under debate.
