Early Psoriatic Arthritis: What Are The First Signs
Psoriatic arthritis is a condition that presents differently in different people, so much so that this form of chronic inflammatory arthritis is categorized into five types and has six key domains. The speed at which people develop symptoms and the severity of these can also vary greatly. Some people slowly develop mild symptoms over time, while others have more severe symptoms that develop quickly.
There is currently no diagnostic test for psoriatic arthritis, so rheumatologists and dermatologists rely on screening questionnaires, skin and joint examinations, x-ray findings and other tests to identify people with this disease.
Early symptom recognition and treatment is thought to be associated with better long-term outcomes in people with psoriatic arthritis, which is progressive and destructive. Even a 6-12 month delay in diagnosis can have an impact on the functional disability and joint damage that people experience.
It is estimated that almost 50 percent of cases of psoriatic arthritis go unrecognized and that significant delays occur during the diagnosis process, which highlights the importance of healthcare providers and their patients becoming more aware of the early signs of the disease.
Causes Of Psoriatic Arthritis
Almost 1 in 3 people with psoriasis also have psoriatic arthritis.
It tends to develop 5 to 10 years after psoriasis is diagnosed, although some people may have problems with their joints before they notice any skin-related symptoms.
Like psoriasis, psoriatic arthritis is thought to happen as a result of the immune system mistakenly attacking healthy tissue.
But it’s not clear why some people with psoriasis develop psoriatic arthritis and others do not.
Early Signs Of Psoriatic Arthritis
Some of the symptoms of PsA are similar to those ofosteoarthritis and rheumatoid arthritis.
If you have psoriatic arthritis, you could experience:
- Joint swelling
- Stiffness, especially in the morning or afterlong periods of inactivity
- Swelling of an entire finger or toe in theabsence of trauma
- Lower back pain

Could It Be Something Else
Psoriatic arthritis can mimic osteoarthritis , gout or rheumatoid arthritis, but each of these forms of arthritis calls for a different plan of action.
There are some helpful diagnostic criteria to rule out other conditions. For instance, if the inflammation comes on suddenly and severely affects a single joint, gout may be to blame.
On the other hand, if the joint in painful but there is hardly any swelling, its more likely that the problem is osteoarthritis. The bottom line is that it can take some time, and several diagnostic approaches, to find the right diagnosis. Work with a doctor you trust, and communicate openly and honestly to help move the process along.

The skin condition psoriasis may start before or after the arthritis. Psoriasis causes a scaly, red, itchy rash on the knees, elbows, scalp, face, and the folds of the buttocks. It can also cause pitting of fingernails or toenails.
Each childs symptoms may vary. Symptoms of psoriatic arthritis may include:
Inflamed, swollen, and painful joints, usually in the fingers and toes
Morning stiffness in the joints
Reddened skin over the affected joints
Sausage-like swelling of fingers and toes, plus swollen wrists
Deformed joints from chronic inflammation
Symptoms in the spine or sacroiliac joint

When To Get Medical Advice
See a GP if you have persistent pain, swelling or stiffness in your joints even if you have not been diagnosed with psoriasis.
If you’ve been diagnosed with psoriasis, you should have check-ups at least once a year to monitor your condition. Make sure you let the doctor know if you’re experiencing any problems with your joints.
Crohns Disease And Other Digestive Problems
Symptoms such as abdominal pain and cramping, blood in your stool, and diarrhea could be signs of inflammatory bowel disease. People who have both psoriasis and psoriatic arthritis are at risk for developing Crohns disease in particular, according to the NPF. This is likely because the mutations in the genes of people who have psoriatic arthritis and Crohns disease are similar, or it may be related to side effects from treatment.
If you struggle with digestive issues, be sure to visit your doctor for an evaluation.

Pso At Increased Risk Of Psa Genetic Markers Distinguishing Pso From Psa
To date, many efforts have been made to characterise the genetics of PsA with early work yielding divergent results. The interpretation of results was complicated by the imprecise serologic definition of HLA alleles and the lack of rigorous PsA classification criteria . Two studies from Canada and Ireland were then published that used newer DNA-based methods of typing HLA alleles and the ClASsification of Psoriatic ARthritis Criteria criteria for case ascertainment . These studies similarly showed that PsA was indeed genetically heterogeneous as not only were some PsA patients HLA-B*27 and others HLA-C*06:02, but additional alleles were found at significantly increased frequencies in these well-classified patient cohorts.
Swollen Fingers Or Toes
The small joints of your fingers and toes are often the first places inflammation and swelling start with psoriatic arthritis. This is called dactylitis, and its extremely common. Somewhere between 32 and 48 percent of people with psoriatic arthritis experience dactylitis.
This swelling can be so bad that your fingers and toes might look a little sausage-like because your entire finger or toe will swell, not just the joint.

Musculoskeletal Problems Cause Many People To Seek Treatment In The 5 Years Before They Receive A Psoriatic Arthritis Diagnosis
Canadian researchers have identified non-specific musculoskeletal symptoms as being common during the pre-diagnosis or prodromal phase of psoriatic arthritis.
While many people will seek treatment for such issues, the researchers found that more than one-third of the psoriatic arthritis patients they studied had visited their healthcare provider for issues such as joint pain and stiffness in the five years before they were diagnosed. In addition, these patients were also more likely to have visited a specialist for their musculoskeletal issues, received injections in affected joints, had joints imaging and visited the emergency room.
Progression And The Later Stages
More developed PsA has a serious impact on daily life. Severe symptoms may make it harder to carry out physical activities or maintain an active social life. Without this activity, joints can become stiff and muscles can become weak.2
About 50 percent of people with PsA have moderate-to-severe fatigue, and about 30 percent have severe fatigue. The combination of joint pain, skin symptoms, and fatigue leads to depression for many people with PsA.3
About half of all people with PsA develop additional conditions. High blood pressure, heart disease, gastrointestinal conditions, and respiratory conditions are common among people with PsA. And a small percentage of people with PsA develop arthritis mutilans, which destroys small bones in hands and leads to permanent deformity.2,3

Children with psoriatic arthritis are at risk of having an eye condition called uveitis. This is an inflammation of the eyes middle layer.
With early diagnosis and treatment, children can go into remission. This means that symptoms go away. But when treatment is delayed, remission is less likely. Then the condition may lead to long-term disability.
Swollen Fingers And Toes
One symptom that is specific to PsA is dactylitis, which causes swollen, âsausage-likeâ fingers and toes.
According to one source, psoriasis often appears during childhood or young adulthood, and PsA usually develops between the ages of 30â50 years.
The National Psoriasis Foundation note that PsA often begins around 10 years after skin symptoms appear.
The foundation also indicate that 10â30% of people with psoriasis will develop PsA.
Authors of a 2016 study noted that 85% of cases of PsA start before the age of 40 years.
They added that 70% of people with PsA experience skin changes before the symptoms of PsA appear, while 15% of people develop skin changes after having symptoms of PsA for around 2 years. Other people may develop both at the same time.
However, both can appear at any time of life.
PsA can have a significant impact on a personâs life, with 40% of people describing it as a âlargeâ problem for them.
Genetics Home Reference note that there are five types of PsA:
- distal interphalangeal predominant
If people notice symptoms of these conditions, they should speak to their doctor.
Current guidelines for the treatment of psoriasis recommend regular screening for these conditions, as they can affect the life expectancy and quality of life of a person with PsA.

What To Watch For
- Lower back
Joints are more likely to be stiff first thing in the morning or after you rest for a while.
Joint warmth and swelling. Along with pain, inflammation can make your joints swollen and warm to the touch.
Nail problems. Psoriatic arthritis can make your fingernails and toenails to lift from their nail beds. It’s a symptom unique to psoriatic arthritis.
Lower back pain. For about 20% of people with psoriatic arthritis, inflammation causes problems with the joints between your vertebrae, a condition called spondylitis. In more severe cases, this can cause joints to fuse together.
Dactylitis. This is when entire fingers or toes swell to look like sausages. Signs of dactylitis can help doctors distinguish psoriatic arthritis from rheumatoid arthritis, which may affect more than one joint.
Eye problems. In some cases, people with psoriatic arthritis also experience eye problems. The same inflammatory process that causes joint problems in can also damage other areas of the body such as eyes. Problems can include:
- Conjunctivitis, which is inflammation of the layer that lines the white of your eye and the inside of your eyelid
Treatments Target Markers In The Blood
Generally, dermatologists treat mild psoriasis in patientswithout PsA with a topical cream or phototherapy that only penetrates the topskin layers.
However, for someone who has PsA and/or moderate to severe psoriasis, pills or injected medications often biologics are needed to control systemic inflammation. There are now many treatment options that effectively control psoriasis inflammation in both the skin and joints.
Topical medications have no way to control systemicinflammation, Dr. Fernandez says. Thats why pills and injectables are soimportant. They can access the bloodstream and can reduce inflammation all overthe body.
While glucocorticoids are a help, injecting them can carry asmall risk of serious joint infection, and side effects make long-term useundesirable. Your doctor will likely screen for active infections or a historyof frequent infections when deciding whether to use this therapy.
Some pills may stimulate liver inflammation. They can alsoreduce blood counts or impair kidney function, he says.

What Is Psoriatic Arthritis In Children
Psoriatic arthritis is a rare form of arthritis or joint inflammation that affects both skin and joints. Psoriasis is an ongoing condition that causes a red, scaly, itchy rash. It also causes nails to become thick and pitted with tiny holes.
Psoriatic arthritis causes painful joint pain and swelling, along with skin rashes. It most often affects finger and toe joints. But it can also affect wrists, knees, ankles, and the lower back.
This condition is most common in adults ages 30 to 50. But it can start in childhood. In many cases, the skin disease starts before the arthritis.
Early diagnosis and treatment helps to ease pain and prevent joint damage from getting worse.
Changes In Your Nails
Youll also want to look for any changes happening with your fingernails or toenails. One symptom of psoriatic arthritis is completely different nail behavior your nails might become infected, change in texture, or even come off of your nail beds.
Common nail changes are pitting, which makes nails look bumpy and dented. Your nails can also separate, or fall off your fingers and toes. If your nails are suddenly changing color and texture, notify your doctor.
Changes in your nails like these are important to note because theyre unique signs of psoriasis and psoriatic arthritis. Noticing any pitting, splitting, or infections can be key to helping your doctor determine if psoriatic arthritis is the cause.

Psoriatic Arthritis Signs And Symptoms
Early symptoms with psoriatic arthritis are important. People will complain of pain and swelling in their joints hands, feet, wrists, etc. They may have a small patch of psoriasis or have psoriasis covering many areas of the body. There may be complaints of stiffness and fatigue. For example, studies in Toronto showed the year before they were diagnosed, people had reported joint pain, fatigue, and stiffness. Early in the disease, people will often have episodes of worsening of the psoriatic arthritis and then episodes of improvement.
Who Treats Psoriatic Arthritis
Health care providers who treat psoriatic arthritis include:
- Rheumatologists, who specialize in arthritis, including psoriatic arthritis, and other diseases of the bones, joints, and muscles.
- Dermatologists, who specialize in conditions of the skin, hair, and nails.
- Physiatrists who supervise exercise programs.
- Occupational therapists, who teach ways to protect joints, lessen pain, perform activities of daily living, and conserve energy.
- Physical therapists, who help to improve joint function.
- Primary health care providers, including family doctors, internists, and pediatricians, who treat problems as they arise and coordinate care between the different specialized health care providers.
- Dietitians, who teach about nutrition and maintaining a healthy weight.

What Are The Early Stages Of Psoriatic Arthritis
In most cases, psoriatic arthritis begins years after the initial presentation of psoriasis symptoms. Psoriasis symptoms include flare-ups of itchy, red, scaly skin.
If you have psoriasis, several things can make you more likely to develop psoriatic arthritis. These risk factors include:
- having psoriasis on your fingernails
- having a family history of psoriatic arthritis
- being between the ages of 30 and 50
- having scalp psoriasis
Like other types of arthritis, psoriatic arthritis often starts with pain and swelling in one or more of your joints. It tends to begin in the smaller joints, such as those in the fingers and toes. But you might also first notice it in larger joints, such as your knees or ankles.
You may also notice swelling in your fingers or toes. This swelling can affect the entire toe or finger, not just the joint.
Soluble Markers Differentiating Pso Vs Psa
As previously noted, detecting PsA in clinical practise is time-consuming and requires a blend of physician experience and radiographic imaging a challenging situation compounded by the lack of serum protein diagnostic biomarkers. This lack of well-validated diagnostic tools means PsA can be often misdiagnosed or underdiagnosed.
Based on a growing panel of candidate biomarkers, Rahmati et al., undertook a computational approach to identify nine alternative signatures obtained by combining clinical and protein markers to improve discrimination between PsA and Pso . 192 PsA and 191 Pso patients, where inflammatory MSK involvement had been excluded, had serum samples taken. Serum samples were tested for sixteen protein markers and this data integrated with four clinical features. The most significant factors influencing classifier performance were nail psoriasis and CRP, followed by SPP1. CRP, DEFA1, LEP, SOST, SPP1, TFCP2 CPII, TNFRSF11B, and nail psoriasis offered the most substantial discrimination between PsA and Pso, but it was noted that further research is required to validate these results . Other recent studies have shown that patients with PsA have higher levels of autoantibodies directed against carbamylated LL37 and ADAMTSL5, both of which are suggested auto-antigens in Pso .

Treatment For Psoriatic Arthritis
Treatment for psoriatic arthritis aims to:
- relieve symptoms
- slow the condition’s progression
- improve quality of life
This usually involves trying a number of different medicines, some of which can also treat the psoriasis. If possible, you should take 1 medicine to treat both your psoriasis and psoriatic arthritis.
The main medicines used to treat psoriatic arthritis are:
- non-steroidal anti-inflammatory drugs
- biological therapies
Spotting Early Warning Signs For A Better Prognosis And Easier Treatment
Psoriasis is well-known for thick, scaly patches of red, itchy skin, but the problem can run deeper than that. Around 30 percent of psoriasis sufferers will also see symptoms of the disease under their skin, in their joints .
The symptoms can come on quite suddenly, or build up over a stretch of time. Some people will notice the inflammation in just one knuckle, while others will suffer extreme joint pain and swelling in several sites around their body.
Living with sore, swollen knuckles can be challenging and discouraging, but psoriatic arthritis is more than a discomfort it can also be quite dangerous if left untreated. However, if you know how to spot the first signs of the condition, you stand a much better chance of bringing it under control and sidestepping permanent complications.

When To See A Healthcare Provider
As a general rule, you should suspect psoriatic arthritis if you have symptoms of psoriasis or a family history of autoimmune diseases. At the same time, it is not uncommon to have multiple autoimmune disorders given that the diseases often share the same genetic mutations.
Early diagnosis and treatment are key to bringing the disease under control. Doing so can help slow disease progression, prevent joint damage, and improve your overall quality of life.
If you develop symptoms of psoriatic arthritis, ask your healthcare provider for a referral to a joint specialist known as a rheumatologist.
While many internists are capable of managing mild psoriasis, psoriatic arthritis is a far more complicated disease. It is not only more difficult to diagnose but often requires a combination of drugs, including disease-modifying antirheumatic drugs like methotrexate and newer-generation biologic drugs like Enbrel and Humira .
