5 Common Causes Of Septic Arthritis

Common Causes Of Septic Arthritis

Common Causes Of Septic Arthritis

When a micro-organism infects a singular or multiple joints in the body, “septic arthritis” is caused. So a likely question in this case is – How is septic arthritis exactly caused? The human joints contain a lubricating fluid, popularly known as “synovial fluid.” What distinguishes this fluid is its quality of being sterile.

However, for a person with septic arthritis this fluid is infested with microbes. The most common attacking agent is fungi, bacteria and virus. However, there are some more causes of septic arthritis. The following will give a detailed list:

Causes Of Septic Arthritis

Bacteria

Bacteria are the most dominant factors causing septic arthritis propagated either through the bloodstream itself or from adjacent tissues. The most prominent bacteria are Staphylococcus aureus, streptococci and E. coli which is a bacterium mostly found in elderly people and those prone to HIV drugs. The bacterium “Haemophilus influenza” was previously dominant in children but now is seen rarely among children with the advent of vaccination. On the other hand, it is mostly seen in people with unhealthy cells.

Bacteria

Problem In Skin

Problems in human skin such as fragility or unhealthy skin are also the causes of septic arthritis. In some skin diseases, such as eczema as well as psoriasis, or in people who are prone to injecting blood into their bloodstreams, it has been observed that the skin heals slowly and disrupts easily.

Problem In Skin

The open area in the skin is constantly exposed to bacterial access which causes septic arthritis. Problem in the skin is thus one of the reasons for bacterial septic in children who are prone to physical exercises and open wounds.

Body Infection

If there is an infection present in any other part of the body, there are chances that septic arthritis will arise. This infection can be present anywhere, such as the upper parts of the respiratory tract or even in the urinary tract. Through the blood stream this infection can travel all across the body and reach a potentially weaker joint. For instance, a surgery that has occurred near or surrounding a joint, a wound puncture and so on, will likely allow germs to enter the joints.

Body Infection

Lack of Immunity

Like many other diseases, another cause of septic arthritis is the weak immune system. For people suffering from weak immune systems, their body lacks the defense mechanism to protect it from external infections.

Lack of Immunity

These would include people who have been suffering from diabetes and need to inject insulin into their blood, kidney problems and have to undergo dialysis and liver problems. They, in order to protect the essential organ of their body have the immune system suppressed with the help of drugs.

Virus

As stated previously, other than bacteria, virus can also cause septic arthritis. The most prominent virus that is responsible for this is “hepatitis A” as well as “B” and “C.” Hepatitis is known for affecting the liver, though each type has distinguishing characteristics of its own. Fortunately, vaccination has helped in lessening it from becoming a dominant cause of septic arthritis. Some other viruses are HIV and HTLV-1 and even “parvovirus B19”. It can also occur from other viral diseases such as mumps and German measles.

Virus

As such septic arthritis is a joint inflammation that can be caused by internally or externally acquired infections. And it is caused usually in people with openings in the skin or an unstable immune system.
