A person with Type 2 diabetes is multiple times more prone to injure a bone than a nondiabetic person. Since the number of individuals with diabetes is increasing quickly in the United States, skeletal fragility in patients with Type 2 diabetes is developing. Despite being still little-known, it is a big public health issue.
Bones are living organs that give structure and protection to the body. Platelets are produced in a living space in bones known as bone marrow and give a consistent supply of minerals including phosphorus and calcium.
Whenever bones are injured, they can fix themselves all alone or with medical intervention. Bones are in a continuous condition of repairing through a process known as remodeling. The risk of bone fractures is higher in people with diabetes particularly in those who take insulin.
The body routinely fixes the micro-fractures that are caused by physical activities. In the healing process of bones, the proteins and minerals are broken down in worn-out regions and are replaced with healthy new proteins.
These new proteins are comprised of amino acids, which normally respond with sugars in the body. Consider how a cut apple progressively browns when exposed to air. The synthetic response between amino acids and sugar inside the body is comparable. Called non-enzymatic glycation, this process happens in tissues all through the body, including in bone.
Non-enzymatic glycation has a browning impact on proteins much the same as an apple would turn brown, creates tiny chemical bridges known as crosslinks. Crosslinks develop in everybody because sugars are present in their bodies. These sugars form naturally, the formation of non-enzymatic cross-links are not good for anyone because they weaken bones by making them more brittle.
The body can easily ménage these crosslinks by breaking them and getting rid of them. But in individuals with Type 2 diabetes, two troubling factors are identified.
The first troubling factor is the presence of sugar in excess in their body. Because sugar is the fuel that participates in the formation of crosslinks. And in diabetic people, there are more crosslinks in bone than normal and healthy individuals. The researchers think that might be the accumulation of these crosslinks is a reason behind more fragile bones in people with Type-2 diabetes.
The subsequent factor is that individuals with Type 2 diabetes have a low level of bone remodeling, which implies their capacity to wipe out crosslinks is decreased. Researchers say this contributes further to the high number of crosslinks in the diabetic bone.
In diabetic patients, crosslinks contribute to complications like kidney damage, vascular damage, and poor eye health.
Researchers found that the hard, thick bone that frames the external shell of bones would, in general, have more crosslinks and more vulnerable mechanical properties in diabetics than in nondiabetics.
They are additionally reenacting high sugar levels in cadaver bone. Even though dead body bone is no longer living but the protein structure is still unblemished. When they incubated these bone samples in sugar solutions, the crosslinks produced due to the reaction between the sugars and the amino acids present in the proteins of cadaver bone.
The researchers are currently working to quantify various kinds of crosslinks to know how fractures might occur in patients. Moreover, they are testing various compounds that may break down bone crosslinks and prevent them from forming in any case. Researchers hope that their work will contribute to several treatments in the future and better medical considerations for people with diabetes.
