Joint involvement is typically, but not always, asymmetric in PsA, while it is predominantly symmetric in RA. Bone erosions, without new bone growth, and cervical spine involvement are distinctive of RA, while axial spine involvement, psoriasis and nail dystrophy are distinctive of PsA.
Even so, the pain and discomfort associated with psoriatic arthritis can be significant. A study published in 2015 in the journal PLoS One found that the overall pain, joint pain, and fatigue reported by psoriatic arthritis patients was significantly greater than that reported by people with rheumatoid arthritis.
“Worsening joint pain and swelling, or new or worsening psoriatic lesions, are the most common red flags that someone is having a PsA flare,” says Yamen Homsi, M.D., the section chief of rheumatology at NYU Langone Hospital in Brooklyn, NY. But there may be other signs that a flare is on the way.
Joint pain, stiffness and swelling are the main signs and symptoms of psoriatic arthritis. They can affect any part of the body, including your fingertips and spine, and can range from relatively mild to severe. In both psoriasis and psoriatic arthritis, disease flares can alternate with periods of remission.
In the absence of a definitive diagnostic test for psoriatic arthritis (PsA), your health care provider will diagnose you by examining your skin, nails, joints and other symptoms. You may have X-rays, an MRI, an ultrasound and blood tests as well.
Psoriatic Arthritis Blood Test: Anti-Cyclic Citrullinated Peptide Test. Blood tests that look for the presence of anti-cylic citrullinated peptide antibodies (anti-CCPs), which are inflammatory, are commonly used to diagnose rheumatoid arthritis, but anti-CCPs can also indicate psoriatic arthritis.
PsA is often undiagnosed and can be misdiagnosed for rheumatoid arthritis (RA) or osteoarthritis (OA), especially in a non-rheumatologic setting [7–9]. RA is a chronic inflammatory arthritis typified by pain, swelling, and stiffness of the joints, particularly symmetric small-joint synovitis of the hands and feet [10].
According to the National Psoriasis Foundation, other PsA symptoms include fatigue, swelling of the fingers and toes, nail changes like pitting, morning stiffness, and uveitis, an inflammatory eye disease. People with psoriatic arthritis may also be predisposed to heart disease, depression, and metabolic disease.
Some people find that psoriatic arthritis leads to another kind of fatigue: brain fog. People have reported problems with concentration, memory and other thinking skills. In part, this fuzzy-headed feeling may be the result of not getting enough sleep at night because of chronic pain.
It happens most often in the fingers and toes.
Diagnosing psoriatic arthritis starts with a physical exam to look for swollen or painful joints, and nail and skin changes. X-rays or scans like ultrasound, MRI or CT can show joint damage. Blood tests may help rule out other diseases, and a skin biopsy can confirm psoriasis.
Answer: It is certainly possible that a person could have both rheumatoid arthritis and psoriatic arthritis. However, doctors, including rheumatologists, generally avoid making multiple diagnoses when a single diagnosis could suffice.
Foods like fatty red meats, dairy, refined sugars, processed foods, and possibly vegetables like potatoes, tomatoes, and eggplants (you might hear them called nightshades) may all cause inflammation. Avoid them and choose fish, like mackerel, tuna, and salmon, which have omega-3 fatty acids.
What does psoriatic arthritis look like on the hands? Common symptoms include pain, swelling, and “sausage” fingers, which may appear shortened. An X-ray may show a “pencil-in-cup” deformity, where the middle of a finger bone becomes narrow while the end of the bone takes on a cup shape.
The Arthritis Foundation lists joint pain, stiffness, skin rashes, fatigue, nail changes, decreased range of motion, and swelling as some of the symptoms of psoriatic arthritis. When you combine these problems, the results can be debilitating. “It's like feeling your bones shatter and crumble.
What does a PsA flare feel like? Early signs of a PsA flare include fatigue together with throbbing pain, swelling, and stiffness in the joints. The tendons may also be painful. In addition, a person may notice swelling in the fingers and toes and worsening skin symptoms.
The most characteristic laboratory abnormalities in patients with psoriatic arthritis are elevations of the erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) level. The results from these laboratory tests help to track the activity of the disease by measuring inflammation.
You'll probably think of skin issues first, but your eyes, heart, lungs, gastrointestinal (GI) tract (stomach and intestines), liver and kidneys may also be affected.
Imaging scans, such as X-rays and MRIs, can help diagnose psoriatic arthritis and show if damage has occurred inside the body. Psoriatic arthritis (PsA) is a chronic form of arthritis, an inflammatory condition that can worsen over time.
If left untreated, psoriatic arthritis (PsA) can cause permanent joint damage, which may be disabling. In addition to preventing irreversible joint damage, treating your PsA may also help reduce inflammation in your body that could lead to other diseases. These other diseases are often referred to as comorbidities.
Generally psoriatic arthritis is a mild condition. With proper treatment and help from others you can relieve joint pain and stiffness and keep skin problems under control. Some people however have a more serious disease and require combinations of medications to control symptoms and prevent joint damage.
Swelling around the ankle is common in psoriatic arthritis affecting the foot. Psoriatic arthritis can lead to shortening or clawing of the toes, hyperextension of the big toe and some in-rolling of the ankle with flattening of the metatarsal arch.
