Summary of "Clinical Predictors of Different Grades of Nonalcoholic Fatty Liver Disease."


BACKGROUND:
Nonalcoholic fatty liver disease (NAFLD) is one of the comorbidities related to obesity. Liver biopsy has been used as the "gold standard" for the diagnosis, grading, and prognosis of obese patients. The objective of the present study was to evaluate clinical predictors of more advanced stages of NAFLD.
METHODS:
In this retrospective study we assessed several physical and laboratorial factors, including some cytokines, in morbidly obese patients submitted to Roux-en-Y gastric bypass that could be related to the diagnosis and staging of NAFLD. Fragments of the livers were obtained from wedge biopsies during operation.
RESULTS:
The medical records of 259 patients were studied. The patients were divided into four groups: normal hepatic biopsy, steatosis, mild nonalcoholic steatohepatitis (NASH), and moderate and severe NASH. There were no differences in cytokine levels among groups. The triglyceride levels were the only variable that could stratify the grades of NAFLD and also differentiate from normal livers in the female patients. Also in this group, the aminotransferases and GGT levels and fasting glucose were predictors of the more advanced stages of NASH, while BMI and weight were predictors of the more advanced stages of NASH in male patients.
CONCLUSIONS:
There are no available markers in clinical practice to detect the initial stages of NAFLD. It is very important to perform a liver biopsy in all patients submitted to bariatric surgery and in obese patients with no indication to be operated in the presence of elevated blood levels of aminotransferases, GGT, and fasting glucose.

Medical and Biotech [MESH] Definitions

Lipid infiltration of the hepatic parenchymal cells resulting in a yellow-colored liver. The abnormal lipid accumulation is usually in the form of TRIGLYCERIDES, either as a single large droplet or multiple small droplets. Fatty liver is caused by an imbalance in the metabolism of FATTY ACIDS.

Lipid infiltration of the hepatic parenchymal cells that is due to ALCOHOL ABUSE. The fatty changes in the alcoholic fatty liver may be reversible, depending on the amounts of TRIGLYCERIDES accumulated.

A syndrome characterized by the clinical triad of advanced chronic liver disease, pulmonary vascular dilatations, and reduced arterial oxygenation (HYPOXEMIA) in the absence of intrinsic cardiopulmonary disease. This syndrome is common in the patients with LIVER CIRRHOSIS or portal hypertension (HYPERTENSION, PORTAL).

Final stage of a liver disease when the liver failure is irreversible and LIVER TRANSPLANTATION is needed.

A distinct and virulent form of DENGUE characterized by thrombocytopenia and hemoconcentration (grades I and II) and distinguished by a positive tourniquet test. When accompanied by circulatory failure and shock (grades III and IV), it is called dengue shock syndrome. (From Dorland, 28th ed)
