Summary
In type 2 diabetes mellitus (T2DM), lean individuals show distinct liver steatosis and fibrosis risk factors compared to nonlean individuals. Management strategies should be tailored based on these differences.
Area of Science:
- Endocrinology
- Hepatology
- Metabolic Diseases
Background:
- Non-alcoholic fatty liver disease (NAFLD) is a growing concern in type 2 diabetes mellitus (T2DM).
- Understanding risk factors for liver steatosis and fibrosis in T2DM patients, particularly differentiating between lean and nonlean individuals, is crucial for effective management.
- Previous studies have primarily focused on overweight or obese populations, potentially overlooking unique aspects in lean T2DM patients.
Purpose of the Study:
- To investigate and compare the prevalence and risk factors of liver steatosis and fibrosis between lean (BMI < 23 kg/m² ) and nonlean (BMI ≥ 23 kg/m² ) patients with type 2 diabetes mellitus.
- To identify specific clinical and metabolic differences associated with liver disease in these two groups.
Main Methods:
- A multicenter study involving 1762 patients with T2DM.
- Transient elastography was used to diagnose liver steatosis and fibrosis.
- Collection of clinical data including diabetes status, serum lipids, inflammatory markers, and body mass index (BMI).
- Analysis of risk factors for liver steatosis and fibrosis in lean versus nonlean groups.
Main Results:
- Prevalence of liver steatosis and fibrosis in the lean group was 44.7% and 23.4%, respectively.
- Lean patients exhibited higher rates of hypertension and cardiovascular disease.
- In lean patients with liver steatosis/fibrosis, older age, longer diabetes duration, lower insulin resistance (HOMA-IR), and lower serum lipids were observed.
- BMI, visceral fat area, and triglycerides correlated with liver steatosis in both groups, but lipid profiles differed.
- Insulin resistance, BMI, and lipid levels were not significantly associated with fibrosis in the lean group.
Conclusions:
- Liver steatosis and fibrosis in lean T2DM patients are less associated with insulin resistance compared to nonlean patients.
- Distinct risk factors for liver steatosis necessitate risk stratification and individualized management approaches for lean and nonlean T2DM individuals.
- Further research into the specific mechanisms driving liver disease in lean T2DM populations is warranted.

1.1K
Lipid metabolism is a crucial process in the human body that involves the synthesis and degradation of lipids. This process is essential for energy production, cell membrane formation, and hormone production, among other functions.
Lipolysis: The Breakdown of Lipids:
Lipolysis is the process of breaking down lipids, particularly triglycerides, into glycerol and fatty acids. This process typically occurs in the adipose tissue and is triggered by various hormones, including glucagon and...

2.2K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

392
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...
