No, there are not just a couple of garden variety types of arthritis out there. In fact currently, there over well over one hundred different kinds of arthritis. Shocking isn't it? Over 100 different types of arthritis make it one very aggressive disease that invades the lives of millions.

One of the less well-known forms of this disease is known as psoriatic arthritis. What is psoriatic arthritis?

We can learn a lot about this disease just from the name of the disease. Guess what? This joint condition is associated with a skin condition often known as "the heartbreak of psoriasis". I know you've heard of that one! Well,psoriasis is a rather common skin condition in which the skin of the body reacts and shows up as red, raised patches on the skin, alligator-like scaly skin and simply an over all, generalized inflammation of the skin. Right now, psoriasis is known to affect around 2% of Caucasian Americans. But it is important to remember that this skin condition can most definitely appear in others besides just the Caucasian population.

The skin condition psoriasis most often affects the scalp, face, navel, tips of the elbows, knees, and areas surrounding the genitals and anus. Health professionals estimate that 10 per cent of all psoriasis patients concurrently develop some form of inflammation in the affected joints. These patients are thus classified as suffering from psoriatic arthritis.

Obviously, one of the major risk factors for developing psoriatic arthritis is the presence of the skin disorder, particularly if it affects the joints. Psoriatic arthritis usually strikes later in life, with most diagnosed cases occurring in the fourth or fifth decades of the patient's life. It appears that gender is not a risk factor, since men and women are affected equally.

While it can vary, the onset of this condition typically follows a predictable pattern. Nearly 80% of those patients battling psoriatic arthritis were diagnosed with the skin condition, psoriasis, prior to being diagnosed with this particular type of arthritis.

The majority of patients experience onset of the diseases at different times. It is common that patients develop psoriasis before experiencing symptoms of psoriatic arthritis. Approximately 80 per cent of psoriatic arthritis patients develop psoriasis before the arthritis.

Psoriatic arthritis is a systematic disease just like other forms of arthritis. With any systemic disease, other areas of the body can be attacked as well. So this simply means that you best be on the look out for problems with other body parts. For example, psoriatic arthritis patients can also be at risk for other problems with the kidneys and lungs. Patients may also experience problems with the heart, the eyes and the mouth. Systemic ... affecting other areas as well. The whole body is at risk.

Unfortunately, when psoriatic arthritis is severe, other terribly important organs can also be attacked. Just like with other varieties of arthritis, psoriatic arthritis can also attack the spine with an inflammatory reaction. This is really true of spondylitis arthritis and reactive arthritis. Again, this is such an important thing to remember so that you are well aware of the potential of inflammatory spinal involvement if you indeed are battling psoriatic arthritis.

What causes psoriatic arthritis? There are many theories, but the cause remains unknown. Most health professionals agree the disease is probably caused by a combination of various environmental factors. Immunity and genetic factors are probably involved as well. There is a gene marker-HLA-B27-that appears in many patients diagnosed with psoriatic arthritis. However, it is not present in all cases.

With psoriatic arthritis, not only does the genetic marker HLA-B27 often show up with these patients, there are also other genetic alterations that may appear. Of course, this just continues to feed into the researchers belief that this variety of arthritis is based in the genes. Another one of the common denominators in the case of psoriatic arthritis is the changes that are seen in the immune system. While we don't know the exact basis of this, those changes are often seen. Also, remember that simple environmental factors may also be a key component behind the reason why people develop this health condition.

Psoriatic arthritis is a battle that many face each and every day. It really does not matter the reason why you developed this version of arthritis in the first place, what does matter is that you are ready to work cooperatively with your doctor in order to build a treatment plan that you can work with and one that is designed to give you the best level of health that you can enjoy. Psoriatic arthritis does not have to be a harness around your neck, but it certainly will become one if you are passive about it. Get to it and educate yourself about your own health condition.
