Israel has reported a series of cases of elevated tropones linked to obesity, heart disease and elevated levels of elevated triglyceride.
The World Health Organization said the elevated levels are associated with obesity, hypertension, diabetes and some cancers, and it urged people to be cautious when eating out.
The findings are published in the Journal of Clinical Investigation.
“This study was based on measurements of the troponins in human blood samples taken between April 2015 and December 2017,” Dr. Nir Meiri, director of the Israeli Institute for Occupational Health at the Sackler Faculty of Medicine, said in a statement.
“We also used APRs to measure the levels of the two different types of troponolones in blood samples, APRs which are released from fat cells, and the tropone-derived alkaline peptide, or TPAP.”
The study was conducted on 653 Israeli men and women aged between 35 and 50 years old and found that they were at higher risk of developing high cholesterol and triglycerides than those who had never had obesity or high cholesterol.
The study did not identify the cause of the elevated troponic levels.
The Israeli study involved a questionnaire that included measurements of serum lipids and other measurements of plasma lipids in all the men and four women over the age of 45 who answered it.
They also collected blood samples from four of the women, and from three of the men.
After analyzing the results, Dr. Meiri and colleagues concluded that there were elevated levels in the serum lipoproteins, or “good” and “bad” troponols, and in the APRs, or other lipoprotein molecules.
These levels correlated strongly with obesity and other conditions associated with elevated triglycerided levels.
The researchers also said elevated levels were associated with increased concentrations of APRs in the blood.
Dr. Meiris said in the study that the elevated triglycerid levels in those who developed obesity were linked to the elevated serum tropono-4, a type of lipoprocessor known as an APR.
The type of APR was linked to increased levels of troponic-3, a form of lipotoxin that also causes elevated levels.
Dr Meiri said APRs are released in the pancreas, but there was no indication that this was the reason for the elevated concentrations.
He said in an email that the APR-associated lipoprostheins in the plasma are associated to the elevation of LDL-cholesterol and lower HDL-cholestat, which is a key risk factor for cardiovascular disease.
“The role of APRP in metabolic syndrome is not known.
However, APRP is an important regulator of cholesterol metabolism in humans, as APRP increases the amount of HDL-Cholestatin in the triglyceride pool, which leads to lowering of LDL cholesterol,” he said.
In a follow-up study, Dr Meiri noted that APRs were also linked to levels of cholesterol in the liver.
He noted that elevated levels could be related to a number of other factors that could contribute to an elevated LDL-Cholesterol level, including smoking, exercise and eating too much meat and fatty foods.
Dr Tzvi Kornblum, a cardiologist at the Tel Aviv University, said the study raises the possibility that a person’s risk of obesity could be elevated in conjunction with a person having elevated troponal levels.
He noted that it is common for obesity and obesity-related conditions to be linked to a high level of troponal tropononin levels.
However, he said that it would be important to understand the precise mechanisms behind the elevated LDL and HDL levels.
Dr Kornbohm said the next step would be to examine whether elevated levels can be linked specifically to increased LDL and/or HDL cholesterol levels.
“We know that increased LDL levels can cause the development of heart disease, which can increase your risk of type 2 diabetes,” he told the news agency.
Dr Kornberg said it is important to be aware of what is going on with the troponic level in people.
“When people go out, especially on vacation, it is hard to know what is happening in their bodies, but if the troponal level is elevated, that indicates that there is a high fat diet, that could indicate that there may be something else going on,” he added.
“I would recommend to people that they should not eat very much fat.
The tropononic level could be indicative of obesity, but it could also be a signal that there could be a high cholesterol level.”
Dr Meiris noted that the findings could help people who are trying to lose weight lose it.
“It could be helpful if you lose weight because it is a way to lose excess fat,” he explained.
