Background: Non-alcoholic fatty liver disease (NAFLD) is one of the most
common diseases in the world, as it is associated with bad food habits. While
no specific treatment for NAFLD, coffee takes renewed interest on progression
of disease.
Aim of the work: to study the possible prophylactic effect of Arabic coffee
and its combination with atorvastatin on experimentally induced non-alcoholic
fatty liver disease in adult male albino rats.Material and methods: 56 adult
male albino rats were used and divided into 7 groups (G) each group 8 rats in
number as the following:G1:control on normal diet , G2: NAFLD group
induced by 2% cholesterol, and groups (G 3 –G7) NAFLD treated groups, G3:
received atorvastatin ( 10 mg/kg/ once daily), G4: received coffee extract (100
mg/kg/twice daily), G5: received coffee extract (200 mg/kg/twice daily), G6:
received coffee extract (400 mg/kg/twice daily), G7:received coffee extract
(200 mg/kg/twice daily) + atorvastatin (10 mg/kg/once daily). NAFLD treated
rats received drugs orally by gavage daily for 9 weeks starting at 5th week from
onset of induction of NAFLD, after that blood samples were collected for
biochemical analysis , and liver carefully excised and cut into two specimens;
one for assessment of oxidative stress, the other liver specimen prepared for
histopathological study.
Results: Cholesterol 2% induced typical picture of fatty changes compared
with control, evidenced by steatosis, ballooning and fibrosis in liver tissue
stained by hematoxylin and eosin (H and E), and Mallory trichrome stains. The
serum level of triglycerides (TG) along with liver index and aspartate
aminotransferase (AST) significantly increased, and the serum level of high
density lipoprotein (HDL) significantly decreased, hepatic level of glutathione
peroxidase (GPx), GSH/GSSG ratio significantly reduced, while hepatic
malondialdehyde (MDA), and serum level of pro-inflammatory cytokine a
tumor necrosis factor- α (TNF-α) elevated significantly. In 200, 400mg/kg
coffee extract treated rats, and coffee + atorvastatin treated rats, the hepatic fat
and collagen markedly reduced, the serum level of triglyceride (TG), liver
index, alkaline phosphatase and hepatic MDA also reduced significantly. The
hepatic GSH/GSSG ratio, GPx enzyme activity in liver in the last three
mentioned groups were significantly higher compared to NAFLD induced
group, the TNF-α also decreased, and anti-inflammatory IL-10 increased in the
previously mentioned groups.
Conclusion: Arabic coffee extract has preventive effect on NAFLD and this
effect due to its hypolipidemic, antioxidant, and anti-inflammatory activity,
and its combination with atorvastatin exhibited synergistic effect on
biochemical and histopathological features of NAFLD.
