Everything about Psoriatic Arthritis
30 percent of Psoriasis patients have psoriasis arthritis. 80 percent of the patients living with psoriasis arthritis have their symptoms on the skin. That is why it is the most easily diagnosable type of psoriasis.
One in five patients living with psoriasis has psoriasis arthritis. The prevalence of psoriasis arthritis ranges from 0.16 to 0.25 percent. However, it may vary in different populations and different ethnicities and locations of the world.
Well, psoriasis is an autoimmune disease. It is a skin disease. To say it is an autoimmune reaction showing its symptoms on the skin. But it also predominantly affects other parts of the body with an increase in severity. One such variant of psoriasis that also affects beyond the skin is Psoriatic Arthritis.
It is common in patients living with psoriasis. It is a kind of oligoarthritis with less intense and characteristic features of its own. Arthritis is an inflammation of joints, stiffened and swollen joints. People with psoriasis catch up with arthritis which is called psoriatic arthritis.
Psoriatic Arthritis starts within no time along with psoriasis. They progress hand in hand with an individual.
In a rarity, say in about 15 to 20 % of patients, arthritis can develop even before psoriasis, signs are noticeable on the skin and other parts of the body. But in general, psoriasis first appears. Occasionally both of them appear together.
This condition is as chronic as psoriasis but has manageable treatments and medications. All those efforts can reduce the impacts and symptoms but cannot cure the disease completely.
These musculoskeletal symptoms are mostly insidious and can not be evident until it is worse. A few may experience only stiffness and pain in the joints. It is indeed easy going, but about one-third of the patients have reported acute onset of the disease.
Rheumatoid arthritis and psoriatic arthritis are both synonymous in signs and symptoms. Both conditions develop sore and painful joints that are swollen. Both the joints or only one of them can be affected in this situation.
Psoriasis itself is an autoimmune disorder, which means parts of the body are attacked by unwanted immunity responses created by our immune system.
Beyond this, the joints and bones also get utterly damaged and in some cases get disabled to a complete extent. This causes inflammation in the joints and bones making them painful, sore, stiffened with swollen appearance.
The tissues and ligaments associated along with those bones and joints at their articulations will be damaged in extreme cases. This can be of two types based on the severity and number of joints affected. Psoriatic arthritis, in general, can affect only one joint or both joints in a person.
Types of Psoriatic Arthritis
There are various patterns in which psoriatic arthritis appears and affects people. They are listed and defined as follows
Asymmetric psoriatic arthritis
- It is a type of psoriatic arthritis, in which both the joints of the same side are affected. It can be told as both left joints or single joints. It is milder in general with almost 35 percent of psoriatic arthritis cases.
- To be precise it is asymmetrical oligoarticular arthritis. It was considered the most prevalent type of psoriasis arthritis for a long time.
- The characteristic sausage-like appearance of the fingers and toes as in dactylitis happens in these patients but asymmetrically. The inflammation starts at the digits of the fingers of both hands and feet, alongside the tendons.
- The knee joint is also seen being affected. The flexions get affected too. Lesser than 5 joints are affected in this type of psoriasis arthritis.
Symmetric psoriatic arthritis
- This is a condition in which the same joints are symmetrically attacked from both sides. This looks like rheumatoid arthritis. Bone deformity and impact on the bones are both low and mild. Almost 50 percent of psoriatic arthritis cases are of this kind.
- This is a severe type of arthritis in which more than four joints are involved and is also the most common.
- The inflammation of distal interphalangeal joints, the symmetrical pattern, the absence of deep lesions, and also testing negative for the rheumatoid factor.
Psoriatic arthritis brings along with it spondylitis, dactylitis, and enthesitis, though they seem individual. They are given the names based on the target attacking sites of psoriatic arthritis in our body.
Spondylitis and Sacroiliitis
- The inflammation can arise anywhere from the neck to the lower back to the least vertebra. The whole spinal column to the tailbone is at risk of being affected in this condition. Inflammation spreads from the neck to the spinal column, vertebra, pelvic areas of the sacroiliac area, and discs and joints on the pelvic floor.
- The tissues, ligaments, and connective tissues associated with the areas also become inflamed. Arms, buttocks, thighs, legs, and feet are affected badly.
- It occurs in 5 percent of the patients with psoriatic arthritis, also men being the main target.
- In this condition, vertebrae are affected asymmetrically unlike the ankylosing spondylitis.
- Paravertebral ossification is seen forming bone structures into the soft tissues around them. Disc calcification results in vertebral fusion and also neurologic complications because of the misalignment of the joints in the spine, and stiffness of the lower backbones. Sacroiliitis pain without stiffness in the lower back can also happen in this type of psoriasis arthritis.
- Sacroiliitis is an inflammation of the sacroiliac joints of the pelvic.
Distal interphalangeal arthritis
- The pain in the distal joints of fingers, their inflammation, and the obvious inflammation of the nail bed, swelling, stiffness, and tuft of the digitals are the characteristics of this type that make it difficult to differentiate it from arthropathy.
- It affects the distal end joints
- Distal interphalangeal arthritis contributes to 10 percent of the psoriasis arthritis cases and is diagnosed in men more than in women.
- Enthesitis is an inflammation in the points of articulation. All the fibrous and fibrocartilaginous, tendons, ligaments, and joint capsules, are inserted into the bones together called entheses.
- An entheses organ consists of fibrocartilage, bursa, fat pad, fascia, and cancellous bone adjacent to it. The inflammation of the entheses is enthesitis.
- Enthesitis is exclusively found in people with psoriatic arthritis. The most affected regions in our body are the ligaments or sole and foot like Achilles’ tendons, pelvic ligaments, ligaments attached to the ribs, and ligaments of the spine.
- Enthesis results in tissue fibrosis and tissue ossification or calcification. Both rheumatoid arthritis and osteoarthritis, enthesitis, and dactylitis cannot be noticed. They are seen only in psoriatic arthritis conditions.
- This is why it is called the hallmark of psoriatic arthritis.
- Dactylitis is a condition of sausages like swollen and deformed fingers and toes.
- The ligaments and tendons around them get inflamed. The feet and also in the second digit of the hands are involved.
- There can be lesions, high chances of injuries, and micro-traumas in dactylitis. The flexor tendons thicken constraining movements. But in severe conditions of dactylitis, the fingers can also be deformed.
- Even though this type has good research and understanding going on, as the study can not harvest human samples, it can be said as underdeveloped. Magnetic resonance imaging and ultrasound are used to test the joints and accumulation of the fluids in the synovial joints.
Psoriatic arthritis mutilans
- It is the most severe yet rarest kind of psoriatic arthritis with 1-5% cases. Its severity can be like rheumatoid arthritis. Psoriatic arthritis mutilans is characterized by the pencil in cup appearance. The digits begin to appear like that with the joints getting dissolved eventually.
- The opera-glass hand is the common symptom of arthritis mutilans in men over women.
- Opera glass hand and pencil in a cup are its key signs.
- Severe arthritis mutilans show involvement of flexion, third, fourth, and fifth digits. Both the distal interphalangeal predominant psoriatic arthritis and psoriatic arthritis mutilans are typical of dactylitis.
- Dactylitis as talked about before is the legit mark of psoriatic arthritis apart from the major symptoms like back pain, swollen toes, feet, etc.
Major Signs and changes in the body:
- Fingers of hands and toes are swollen, painful, and look like sausages as in dactylitis in 35 percent of patients.
- Skin lesions, nodules, erythematous skin and plaques, guttate lesions, nail psoriasis and nail traumas, inverse psoriasis, lakes of pus, and microtraumas happen in psoriatic arthritis alone.
- In some cases, the fingers and nails might develop deformities. The time where the worsening of disease signs in the fingers starts is also the beginning of psoriatic arthritis.
- Enthesitis of the ligaments, tendons, insertions into bone, Achilles he dons, plantar fascia, and cancellous bone are one sign of psoriatic arthritis.
- Cracking of the edges of the nail, pitting of the nails uniformly, ridging on the nails transversely, the appearance of tiny blood dots under the nails, half moon nails, hyperkeratosis, beau lines, etc are the nail changes in the psoriatic arthritis
- Fatigue happens because the body gets drained of energy with the painful joints, inflammation, and also the tiring medications that are taken to get down psoriatic arthritis.
- Exercise, eating, and sleeping well make a person feel better.
- Rib and chest pains, as said because the ligaments of the rib cage and cartilage of the chest bone also get affected in psoriatic arthritis.
- In the rarest instances, the blood vessels of the heart also called aortas can get affected.
- Nails, get separated from the nail bed, get deformed to greater extents, pits, and ridges are formed on the nails.
- Discoloration of the nails, and onycholysis cause yellowish and green nails. Dents in the nails can be noticed.
- Subcutaneous nodules are rare but also present in psoriatic arthritis.
- The conjunctiva of the eyes may get involved by 20 percent, ocular involvement by 30 percent and 43 percent of the sacroiliitis may be involved in psoriatic arthritis
- Psoriasis affects almost 1 percent of the total population. In almost 5 percent of psoriatic Arthritis cases, the joints in the feet and hands get deformed.
Diagnosis of Psoriatic Arthritis:
For diagnosing a psoriatic arthritis case, one should consult a rheumatologist. They deal with such inflammatory diseases both autoimmune and acquired. No blood tests are needed to identify the type of psoriatic arthritis. All of the patterns of psoriatic arthritis mentioned above are scaled on scores based on the physical examination entirely. Each of them has an established analogue scale to assess the range of symptoms.
- The score of current psoriasis, a history of ps, psoriasis in the family, the inheritance pattern, the patient history of psoriasis, the dactylitis examination, examination for new bone formations, testing negative for rheumatoid factor, and nail dystrophy are essential to list to be assessed for psoriatic arthritis.
- On primary examination, a few x Rays or MRIs are prescribed for diagnosis. The new formations around bone and joints, deformities, etc, can be traced through those investigations. The uric acid quantity is taken into consideration as in gout disease to estimate the extent of inflammation. Ultrasounds can also be prescribed by the rheumatologist if needed. Blood tests are rarely asked for, in the case of monitoring therapies.
- All the radiographic findings look for joint space narrowing, fluffy periostitis, soft tissue swell, sacroiliitis, enthesitis, erosion, synovitis, inflammation of small joints, pencil in cup deformity, and also intervertebral bony bridges in the spine.
- Lab findings include serum immunoglobulin tests, rheumatoid factor test, erythrocyte sedimentation rate and c reactive protein levels test, and complete blood count.
Psoriatic arthritis if neglected can attract various other problems with it like deformation of fingers and toes, obesity, high blood pressure and high uric acid, inflammations of the eyes, nerves, blood vessels, cardiac diseases, depression, stress, bone density changes, atherosclerosis and skin diseases becoming chronic and unyielding.
Psoriasis Arthritis Treatment:
The treatments for psoriatic arthritis are more of a regimen to follow. All of them assure a relaxation from the aggravating disease symptoms. However, they are prescribed based on the patient’s health history, budget, disease activity, severity, patient choice, comorbidities, lifestyle, and also mental strength. Whatever the treatment plan is, a consistent regime is necessary for relief from the symptoms.
- DMARDS are indicated for the treatment of inflammation and inflammatory diseases. In psoriasis arthritis, they have been proved well for management. Although there are many options like sulfasalazine, cyclosporine, leflunomide, and other biologic agents belonging to this class, methotrexate is considered the best.
- Methotrexate is the most commonly used DMARDs at the beginning. This specific class of drugs are utilized in the treatment plan for the remission of the disease, to lower the disease activity and severity, and also to halt the further progression of the disease. The treatment for arthritis can either be combination therapy or monotherapy, but uses disease-modifying anti-rheumatic drugs as an agent.
- Secukinumab is an interleukin. It is a fully monoclonal antibody and selectively targets inflammatory cytokines. These targeted biological therapies are replacing immunosuppressants vastly with their efficacy. Biologics like interleukin 1,2 and 23, and interleukin 17 are taken advantage of.
- The treatment strategy begins with non-steroid anti-inflammatory drugs also called NSAIDs along with local glucocorticoid injections as initial therapy. For the patients with joint damage, such as dactylitis, poly or monoarthritis, or oligoarthritis the treatment demands the rapid use of conventional systemic disease-modifying antirheumatic drugs.
- If the desired immune suppression is not achieved by this, biologics come into plan. The biological disease-modifying antirheumatic drugs that target the specific cytokines are opted for. Interleukin 12/23, interleukin 17A if necessary a tumor necrosis factor inhibitor, TNF also should be used as the first line of treatment. If the biologic DMARDs also fail, the Janus kinase inhibitors are introduced primarily.
- For a person with mild disease, phosphodiesterase -4 inhibition is proposed for patients.
The management of psoriasis arthritis is both non-pharmacological and pharmacological. Keeping the musculoskeletal aspects of the disease, severity, and spread recommendations of these drugs vary.
What to expect from Psoriasis Arthritis Treatment
- There is no cure for Psoriatic Arthritis.
- Psoriatic arthritis treatment focuses on reducing joint inflammation, reduces joint pains.
- Treatments depend on the severity of the disease.
- One can have a flare of the symptoms if the treatment is discontinued.
- Patients may experience side effects of the medication and treatment when they are used for a long period.
- Sometimes treatment may not work for all the patients.
As there is no permanent cure for psoriatic arthritis and due to side effects of medicines many patients opt for alternative treatment such as Ayurveda.
Along with medicines lifestyle and diet are important to manage your psoriatic arthritis effectively.
