Early Stages Of Psoriatic Arthritis
Recognizing the signs of psoriatic arthritis can be tricky since symptoms differ from patient to patient. For example, one person can experience psoriasis skin involvement and peripheral arthritis, another may experience axial disease , and someone else could have a combination of all three.
Whats more, especially during early disease, you may confuse your symptoms with other conditions. People can mistake enthesitis, inflammation of the entheses for tennis elbow or dactylitis for an infection, explains Dr. Mikulik.
If you have psoriasis and are having pain in your tendon and musculature and you think maybe Ive been too active lately, that may be the first sign of PsA, says Dr. Haberman. Doctors commonly hear people chalk up their symptoms to overuse, such as getting more exercise than usual or doing work around the house.
If you experience any of the following signs of early psoriatic arthritis its important to see your doctor as soon as possible:
- Back pain
- Changes in your fingernails or toenails, including holes, pitting, discoloration, or softness
- Eye inflammation
- Sausage-like swelling of an entire finger or toe
- Scalp psoriasis
- Skin rash
- Tendon or ligament pain at the Achilles tendon, bottom of the foot , or elbow
Whats The Dosage Of Enbrel For Children
For the dosage used in children with polyarticular JIA, see the section above.
Enbrel can be used in children ages 4 to 17 years with plaque psoriasis. The dosage is based on weight:
- For children who weigh 138 lb* or more, the typical dosage is 50 mg given once per week.
- For children who weigh less than 138 lb* the typical dosage is 0.8 mg per kg of body weight given once per week. Your childs doctor or a pharmacist will calculate the correct dose.
* 138 lb equals 63 kilograms .
How Are Enbrel And Humira Alike And Different
Both Enbrel and Humira are biologic medications. Biologic medications are made from living cells. Enbrel and Humira are also both injections. And they work by lowering the activity of your immune system.
These two drugs target the same part of your immune system. They both block the activity of a protein called tumor necrosis factor .
These drugs also share the same side effects. And both have for serious infections and cancer. Boxed warnings alert people to serious side effects of a drug. These are the most serious warnings about a drugs side effects.
Both Enbrel and Humira can be used to treat:
Doctors can prescribe Enbrel for adults and some children with plaque psoriasis. But Humira can only be used to treat plaque psoriasis in adults.
If youd like to know more about the differences and similarities of these two drugs, talk with your doctor.

This drug comes with several precautions.
Etanercept And Narrowband Ultraviolet Light B
A multicenter, open-label, single-arm prospective study evaluated the efficacy of etanercept 50 mg twice weekly in combination with NB-UVB 3 times weekly in patients with moderate to severe psoriasis . After 12 weeks, the percent of patients achieving a PASI 75 response was 84.4%. The percentage of patients who achieved a PASI 90 or PASI 100 response was 58.1% and 26%, respectively. In this study, the combination of etanercept and NB-UVB was efficacious and generally well tolerated with no increase in photosensitivity noted. The addition of NB-UVB may serve as an option for the subset of patients who experience worsening of psoriasis after stepping-down from the induction dose. Caution should be used when starting etanercept for patients with known or suspected skin cancers due to case reports of squamous cell cancers that grew rapidly from pre-existing suspicious lesions after initiation of etanercept therapy.

How Safe And Effective Is Etanercept
Etanercept, in the form of Enbrel, has been used to treat psoriasis in the UK since 2006. Real-world safety and effectiveness data is being compiled by the British Association of Dermatologists Biologics and Immunomodulators Register and the British Society for Rheumatology Psoriatic Arthritis Register . The National Institute for Health and Care Excellence recommends that all patients receiving biologic therapy, who provide their consent, are entered onto these observational study registers.
Who Can Take Enbrel
Enbrel is approved for treating patients 4 years old and above with moderate-to-severe plaque psoriasis who need treatment with phototherapy or systemic treatments. It is not suitable for women who are pregnant or breastfeeding3.
Before prescribing Enbrel, healthcare providers need to know if the patient4:
- has or has had heart failure
- has a surgery planned
- has or has had a nervous system condition, like multiple sclerosis or Guillain-Barre syndrome
- has been in contact with someone with chicken pox
- is allergic to latex

Dosage For Plaque Psoriasis
If you have moderate to severe plaque psoriasis, you may start off using 50 mg of Enbrel twice a week for the first 3 months. This is called a loading dose.
Loading doses are higher doses at the start of treatment. These higher doses help the medication to start working faster in your body.
After the first 3 months, youll switch to a maintenance dose. The standard maintenance dose is a 50-mg injection once every week.
In some cases, you may start out with 25- or 50-mg injections once per week. In this case, you would not have a loading dose. Depending on factors like how severe your condition is, your age, and other medical conditions, your doctor will determine the best way to start your treatment.
Enbrel For Polyarticular Juvenile Idiopathic Arthritis
Enbrel is also approved to treat moderate to severe polyarticular juvenile idiopathic arthritis in children ages 2 years and older.
Polyarticular JIA is a type of arthritis that occurs in people younger than 18 years old. It causes swelling and pain in five or more joints. Its not known what causes polyarticular JIA.
Although polyarticular JIA may cause pain in any joint, the most commonly affected areas are small joints in the fingers and hands.
Enbrel works by decreasing the swelling in joints. This helps make it easier and less painful for children with polyarticular JIA to move their affected joints.
In clinical trials of children ages 2 to 17 years old with polyarticular JIA, 74% saw a decrease in symptoms after 3 months of taking Enbrel. After 3 months, children were split into two groups: those who continued to take Enbrel and those who started taking a placebo .
In the second part of the trial, about 77% of children taking a placebo had an arthritis flare-up. In comparison, 24% of children taking Enbrel had a flare-up. Children taking Enbrel didnt have their first flare-up of symptoms until at least 116 days after starting treatment. Children taking a placebo had their first flare-up 28 days after starting treatment.

Is Enbrel An Nsaid
No, Enbrel is not an NSAID. Enbrel belongs to a class of medications called tumor necrosis factor blockers. TNF can cause inflammation in your body. Enbrel works by blocking this inflammation, which can help your condition improve. Enbrel can be taken along with NSAIDs for added benefit. Examples of NSAIDs include ibuprofen and naproxen . Talk with your doctor if youre interested in taking an NSAID with Enbrel.
Creating Humira And Enbrelrecombinant Dna Technology
Recombinant DNA technologies are the methods that have been developed to splice two or more individual gene segments together with the intent to design a protein that possesses particular qualities or activities. In a very simplified version of normal gene expression, a gene, made up of a double helix of DNA, is “transcribed” by certain cell components to form a single strand of RNA. The RNA strand can then be “processed” through other cell “machinery” to create specific proteins that the cell then uses to send signals, or messages, to yet other cell components, or that carry out specific functions critical to cell metabolism, such as peptides, cellular membrane portals, or activation factors. Many things can happen along this pathway to modify the protein and its specific functions or activities. Recombinant DNA technology takes advantage of these processes to customize and synthesize a final protein product for use as a drug, as is the case with these biologics.

What If I Miss A Dose
If you miss your doses of medication, take it as soon as you remember. Never take two injections at once, as this can cause very serious side effects. If youre unsure whether to skip a dose or when to take your next dose, talk to your doctor or pharmacist.
To help make sure that you dont miss a dose, try setting a reminder on your phone. A medication timer may be useful, too.
Can Psoriatic Arthritis Affect Other Parts Of The Body
Having psoriatic arthritis can put you at risk of developing other conditions and complications around the body.
The chances of getting one of these are rare. But its worth knowing about them and talking to your doctor if you have any concerns.
Eyes
Seek urgent medical attention if one or both of your eyes are red and painful, particularly if you have a change in your vision. You could go to your GP, an eye hospital, or your local A& E department.
These symptoms could be caused by a condition called uveitis, which is also known as iritis. It involves inflammation at the front of the eye.
This can permanently damage your eyesight if left untreated.
Other symptoms are:
- blurred or cloudy vision
- sensitivity to light
- not being able to see things at the side of your field of vision known as a loss of peripheral vision
- small shapes moving across your field of vision.
These symptoms can come on suddenly, or gradually over a few days. It can affect one or both eyes. It can be treated effectively with steroids.
Heart
Psoriatic arthritis can put you at a slightly higher risk of having a heart condition. You can reduce your risk by:
- not smoking
- staying at a healthy weight
- exercising regularly
- eating a healthy diet, thats low in fat, sugar and salt
- not drinking too much alcohol.
These positive lifestyle choices can help to improve your arthritis and skin symptoms.
Talk to your doctor if you have any concerns about your heart health.

How Does Enbrel Injection Work On Psoriasis
Psoriasis is associated with the immune system and occurs due to the overproduction of T-cells. Enbrel injections inhibit this overproduction of cells. Enbrel reduces the symptoms associated with psoriasis such as red and itchy patches, swelling and hardening of joints, etc. It is also specifically used in the treatment of psoriatic arthritis.
Excess amount of these injections can cause some side effects so using a small dose of these injections in combination with Ayurvedic medicines provides better treatment for Psoriasis. Gradually use of injections can be stopped after restoration of the disease to some extent and after that treat the disease naturally with Ayurvedic herbs.
In Ayurveda, any skin disorder is categorized as khustha-Roga. Psoriasis resembles Ek-Khustha and kitbha khustha. In Ek-Khustha the skin looks like fish skin or there is a lack of sweating. In Kitbha-Khustha the affected part of the skin becomes coarse like a wound and turns into greyish-black color.

Taking Care Of Yourselfthe Choice Is Yours
Strictly approved for those with moderate to severe psoriasis, these and the other biological response modifiers that are on the market have shown some promise in relieving the symptoms and discomfort experienced in psoriasis and psoriatic arthritis. But to date, all come with serious risks of severe infection, disease, and even death. Great care should be taken when considering their use. A good starting point for undertaking such considerations is arguably one that includes making deliberate diet and lifestyle changes that promote systemic good health: Eliminate any dietary, environmental, and emotional factors that trigger or exacerbate psoriasis flares. Ensure any nutritional gaps are covered by taking a high-grade multivitaminmineral complex daily. Avoid unhealthy lifestyle choices that compromise one’s general good health. If one can make deliberate improvements to one’s general state of health, this launching point is optimum for finding lasting, effective relief through any number of psoriasis treatments available.
Dosage For Polyarticular Juvenile Idiopathic Arthritis
Enbrel can be used in children ages 2 years and older for polyarticular juvenile idiopathic arthritis. Children who weigh 138 pounds or more will receive one 50-mg injection each week.
For children who weigh less than 138 pounds , one injection is given each week. The dose is based on weight.
The milligram strength is calculated as 0.8 mg/kg. For example, if a child weighs 42 pounds, that equals about 19 kg. The dose is calculated as 19 kg multiplied by 0.8 mg/kg, resulting in a dose of about 15 mg. Your childs doctor or pharmacist can calculate the correct dosage for you.
Enbrel prefilled syringes and autoinjectors only come in doses of 25 mg or 50 mg. You need to use the powder for a dose other than 25 or 50 mg.
The powder comes as 25 mg/mL and must be mixed before use. Once the powder is mixed, you can draw out the exact amount of medication that you need. So for the example above, you would draw out 0.6 mL of medication for a dose of 15 mg.
Weight-based dosing should never be greater than one 50-mg injection per week.
In juvenile idiopathic arthritis, children may continue taking steroid medications, anti-inflammatory medications, or pain medications that help relieve symptoms.
