Is It Gout Or Arthritis

Specific Us Features In Gout

What is gout arthritis? How does uric acid cause inflammation?

Articular cartilage double contour Sign

DCS is very specific for gout. It is defined as abnormal hyperechoic band over the superficial margin of the articular hyaline cartilage, independent of the angle of insonation and which may be either irregular or regular, continuous or intermittent and can be distinguished from the cartilage interface sign .

DCS is reported in acute flare-up in clinically uninvolved joints, and in patients with asymptomatic hyperuricemia . False-positive results have also been reported , . Threle and Schlesinger demonstrated that DCS can disappear when SUA levels were lowered to 6 mg/dl for 7 months or more .

    A tophus is a circumscribed, inhomogeneous, hyperechoic, and/or hypoechoic aggregation , which may be surrounded by a small anechoic rim. Aggregates are heterogeneous hyperechoic foci that maintain their high degree of reflectivity even when the gain setting is minimized or the insonation angle is changed and which occasionally may generate posterior acoustic shadow.

    Tophi have been also described by US as wet sugar clumps with an oval or irregular shape .

Gout Attack Vs Chronic Gout

It is possible to have a gout flare-up and never experience another. Repeated instances of acute gout are called chronic gout17.

The treatment goals for a gout attack are different than those for chronic gout. When treating a gout attack, the goal is to relieve pain and inflammation. When treating chronic gout, the goal is to prevent future gout attacks and long-term joint damage.

While some people with chronic gout may get frequent gout attacks, others may have years in between attacks. If chronic gout is not treated, attacks may become more frequent and/or last longer.

Left untreated, a gout attack will usually resolve itself within a few days or weeks. Chronic gout can permanently damage a joints tissues and decrease its range of motion. For this reason, it is important to recognize symptoms, understand risk factors, get an accurate diagnosis, and treat and prevent gout.

Clinical Significance And Research

In human , the of uric acid is typically 3.47.2 mg per 100 mLl for men, and 2.46.1 mg per 100 ml for women . Uric acid concentrations in blood plasma above and below the normal range are known as, respectively, and . Likewise, uric acid concentrations in urine above and below normal are known as and . Uric acid levels in saliva may be associated with blood uric acid levels.

The Role Of Diet In Gout Prevention

Dietary control may be sufficient in a patient with mildly elevated uric acid, for example, 7.0 mg/dL

For those with a higher level, for example, 10.0 mg/dL, diet alone will not usually prevent gout. For the latter, even a very strict diet only reduces the blood uric acid by about 1 mg/dL- not enough, in general, to keep uric acid from precipitating in the joints. The cutoff where patients with gout seem to dramatically reduce their number of attacks is when their uric acid level is taken below 6.0 mg/dL.4

Getting Prompt Treatment For Gout Or Ra

Gout Associated With Psoriatic Arthritis, Psoriasis in ...

If youve been experiencing symptoms of either condition, you should see your doctor as soon as possible because both can cause significant joint damage if a diagnosis is delayed. However, Dr. Portnoff notes that the pain gout causes is so intense that patients with gout rarely put off seeing a doctor when theyre having an attack.

Theres no cure for gout or RA, but there are several good treatments available for the two conditions. Some pain relief treatments, including NSAIDs and corticosteroids, are recommended to help manage both RA and gout. Because RA is an autoimmune disease, patients may also take disease-modifying immunosuppressant drugs such as methotrexate or other DMARDS or biologics.

Gout, on the other hand, may be treated with the drug colchicine, which relieves pain and helps prevent future attacks. Rheumatologists may also prescribe drugs called xanthine oxidase inhibitors , and sometimes combine those with medications called uricosuric drugs that improve your kidneys ability to remove uric acid from your body. People with gout are also advised to limit foods that promote high levels of uric acid, including red meat, alcohol, and shellfish. However, diet changes alone cannot usually control gout symptoms, and medications are necessary to help prevent complications.

What Does A Gout Attack Look And Feel Like What Would A Foot Or Toe With Gout Look Like

When gout occurs, the joint tends to be extremely painful and is warm, red and swollen . The inflammation that is part of a gout attack is systemic, so that fever and chills, fatigue and malaise are not uncommonly part of the picture of a gout attack.

Figure 6: Toe with Acute Attack of Gout

Gout attacks can occur in joints that look normal, or in joints that have easily visible deposits of uric acid. These deposits are called tophi and can be in numerous locations, but especially on the feet and elbows. In Figure 9, the little finger of the right hand is bandaged since fluid was just removed from it, which demonstrated innumerable uric acid crystals.

Figure 7a: Tophi on Foot

Figure 7b: Tophus Over Achilles’ Tendon

Figure 8: Tophus on Elbow

Figure 9: Tophi on Hands

Figure 10: Large Tophus of Finger

While some gout attacks will solve quickly by themselves, the majority will go on for a week, several weeks, or even longer if not treated. Since gout attacks are usually quite painful and often make walking difficult, most gout sufferers will request specific treatment for their painful condition.

How To Distinguish Gout From Ra

It can be confusing to tell the difference between RA and gout, so here is some helpful background information to help distinguish between the two:

1. Which joints are involved?

Gout is most common in the big toe, at the joint where the toe meets the foot. Gout is also common at the ankles, midfoot, knees, and elbows. It is usually in later stages of gout when small joints in the hands are involved. RA, however, tends to involve the smaller joints in the hands early on. The pattern of joint involvement is very helpful to physicians in differentiating between gout and RA.

2. What does a gout attack feel like?

If someone thinks they are getting a gout attack, they should look out for the joint’s turning red, which is more common in gout than in RA. While RA is painful, a gout attack is often so intense that the sufferer has great difficulty walking. People with RA can have difficulty walking as well, but the sudden intensity and immediate loss of function is usually more dramatic in gout. The onset of RA pain is more gradual, while the pain from gout generally reaches its peak within 24 hours.

3. What is a uric acid level, and why is it important?

Luckily, gout is an extremely treatable condition, so getting a proper diagnosis and appropriate management is critical. For more information, please visit CreakyJoints.org/goutsurvey.

Medications For Acute Gout

  • Non-steroidal anti-inflammatory agents and COX-2 inhibitors are the mainstay of therapy of acute attacks of gout in patients who have no contra-indication to them. These medications include such agents as naproxen , ibuprofen , celecoxib , indomethacin and many others. These agents reliably decrease the inflammation and pain of gout. However, patients with ulcers, hypertension, coronary disease, and fluid retention must be careful with these agents, even for the short courses needed to resolve a gout attack. The doses of non-steroidal anti-inflammatory agents needed to resolve a gout attack are on the higher side, since full anti-inflammatory effect is needed. See examples of dosage in Table 2. Over-the-counter dosage levels, for example, ibuprofen at 200mg, two tabs three times a day, are often insufficient.
  • Corticosteroids, such as prednisone and methylprednisolone , are anti-inflammatory agents that are quite effective against gout attacks. Anti-inflammatory steroids are very different in action and side-effects as compared to male hormone steroids. Anti-inflammatory steroids have long-term risks, such as bone thinning and infection, but their risk for short-term therapy is relatively low. These agents can raise blood pressure and blood sugar, so can be a problem for those with uncontrolled hypertension or uncontrolled diabetes mellitus.

    Gouty Arthritis Causes | Dr. Sievers discusses what causes gouty arthritis

    Your body doesnt typically excrete enough uric acid on its own to minimize the risk of a gout attack. Lab-grade Chanca Piedra is that extra added push for your body to be able to not only flush out uric acid in the kidney and liver, but to also inhibit the formation of uric acid crystals. Chanca Piedra has also been shown to help with inflammation.

    To dissolve uric acid crystals or to prevent them from forming altogether:

  • Take 400mg of lab grade chanca piedra when you wake.
  • Wait one hour before eating to ensure maximum uptake of the herb.
  • Take 400mg of lab grade chanca piedra at night.
  • Once your gout attacks are under control, scale back to just 400mg per day.
  • Keep in mind that each individual is unique and will respond differently to each treatment type. Always discuss any new treatments that you are considering with your physician prior to starting them so he/she can review with you any potential medication interactions and potential side effect concerns.

    Signs And Symptoms Of Gout

    Any joint can be affected by gout, but it usually affects joints towards the ends of the limbs, such as the toes, ankles, knees and fingers.

    Signs and symptoms of gout include:

    • severe pain in one or more joints
    • the joint feeling hot and very tender
    • swelling in and around the affected joint
    • red, shiny skin over the affected joint

    Symptoms develop rapidly over a few hours and typically last three to 10 days. After this time the pain should pass and the joint should return to normal.

    Almost everyone with gout will experience further attacks at some point, usually within a year.

    When Is Surgery Considered For Gout

    The question of surgery for gout most commonly comes up when a patient has a large clump of urate crystals , which is causing problems. This may be if the tophus is on the bottom of the foot, and the person has difficulty walking on it, or on the side of the foot making it hard to wear shoes. An especially difficult problem is when the urate crystals inside the tophus break out to the skin surface. This then can allow bacteria a point of entry, which can lead to infection, which could even track back to the bone. Whenever possible, however, we try to avoid surgery to remove tophi. The problem is that the crystals are often extensive, and track back to the bone, so there is not a good healing surface once the tophus is removed. In some rare cases, such as when a tophus is infected or when its location is causing major disability, surgical removal may be considered.

    Since it is hard to heal the skin after a tophus is removed, a skin graft may be needed. For this reason, we often try hard to manage the tophus medically. If we give high doses of medication to lower the urate level, such as allopurinol, over time the tophus will gradually reabsorb. In severe cases, we may consider using the intravenous medication pegloticase , since it lowers the urate level the most dramatically, and can lead to the fastest shrinkage of the tophus.

    Gout May Be Your Second Arthritis

    Did you know that it is possible to have more than one form of arthritis? Get more information about gout, the inflammatory condition that can occur with osteoarthritis, rheumatoid arthritis and psoriatic arthritis.

    It is possible to have more than one type of arthritis, and knowing what you have can help in treating your symptoms.Gout, which can occur with OA, rheumatoid arthritis and psoriatic arthritis , results when uric acid crystals are deposited in joint tissue. It causes sudden, severe pain, swelling and tenderness, usually in the big toe, but it also can occur in the feet, ankles, hands, knees, wrists, elbows or other joints. Its typically in only one joint, but chronic gout can affect multiple joints. Differentiating between gout and other forms of arthritis is critical because the treatments are very different. If you think you have gout, see your doctor. The sooner its treated, the sooner youll get pain relief.

    How Gout may Affect Other Arthritis Conditions

    Gout and RA

    For decades, rheumatoid arthritis and gout were thought to be mutually exclusive. But some people with RA also get gout as both conditions share obesity as a common risk factor and may cause kidney problems. Diagnostic tools like synovial fluid analysis and dual-energy CT scans are especially helpful in making the correct diagnosis.

    The Role Of Medication In Prevention Of Gout

    Acute Gouty Arthritis

    Table 3: Medications to pevent attacks of gout

  • Colchicine: to decrease the ability of uric acid crystals to cause inflammation.
  • Allopurinol and febuxostat: to decrease production of uric acid
  • Probenecid and lesinurad: to increase the excretion of uric acid
  • Pegloticase: to increase the breakdown of uric acid
  • Standard medications in preventing gout attacks

    i. Colchicine : using the matches analogy discussed above1, using colchicine can be seen as dampening the uric acid matches. Colchicine does not lower the bodys store of uric acid, but it decreases the intensity of the bodys inflammatory reaction to these crystals. Recent studies have shown that at least one mechanism of colchicines action is by acting to prevent a cascade of reactions that lead to the production of interleukin 1-beta, which is an inflammatory protein , which is important in gouty inflammation.8

    ii. Allopurinol: This agent is presently the most commonly used drug for the prevention of gout. Allopurinol blocks the enzyme xanthine oxidase, which blocks the breakdown of purines, thus decreasing the bodys total amount of uric acid. Allopurinol is effective in preventing gout no matter what the mechanism of the elevated uric acid was. Whether a person is making too much uric acid, or has difficulty excreting it via the kidney, allopurinols decrease in uric acid production leads to the same goal: a decreased total body uric acid.

    What Else Should I Ask My Healthcare Provider About Gout

    Consider asking your healthcare provider:

    • What is causing the gout?
    • Do I have any joint damage?
    • What can I do to prevent future attacks?
    • Can any gout medications help me?
    • How long will I need to take gout medications?

    A note from Cleveland Clinic

    Gout is a painful form of arthritis. Extra uric acid in your body creates sharp crystals in the joints, leading to swelling and extreme tenderness. Gout usually starts in the big toe but can affect other joints. Gout is a treatable condition, and the uric acid level can be decreased by medication and lifestyle changes. Talk to your healthcare provider about medications that can reduce uric acid levels. They can also discuss changes you can make to your diet and lifestyle to prevent and reduce gout attacks.

    The Sharp Pain During A Gout Flare Can Usually Help Distinguish The Two

    At first glance, it might seem like gout and rheumatoid arthritis arent so different. Both cause pain, swelling, and stiffness of the joints that can limit your range of motion. However, the cause differs. RA is an autoimmune disease, which means the bodys own immune system attacks the joints, whereas the pain of gout is due to elevated levels of uric acid in the blood. But despite some similarities in symptoms, rheumatologists usually dont have much trouble telling the two conditions apart.

    Cases of gout are often clear-cut because the flash of pain patients experience during a flare is so dramatic, says Kelly A. Portnoff, MD, a rheumatologist at The Portland Clinic in Portland, Oregon. It feels like a hot poker in their joint. Whereas if you have RA, the pain kind of creeps up on you.

    A patients age also provides clues. While rheumatoid arthritis can affect almost anyone, it most often first appears in women in their reproductive years. Gout tends to arise in one of two life stages: the late twenties/early thirties and the seventies and eighties.

    When gout strikes earlier, its often due to lifestyle factors that promote high levels of uric acid, such as meat-heavy diet and excessive alcohol intake, Dr. Portnoff says. When gout appears later in life, its more likely the result of kidney damage or health conditions that increase the risk of gout, such as high blood pressure, diabetes, and heart disease.

    Treating A Gout Attack

    Treating an attack of gout doesnt lower your urate levels or stop future attacks. The treatment helps you to manage your symptoms when an attack happens.

    The most commonly used drug treatments for attacks of gout are:

    Some people will be better suited to NSAIDS, while others will be suited to colchicine. But your preference is also taken into consideration many people with gout quickly learn what works best for them.

    In cases where one drug doesnt seem to be working on its own, your doctor might suggest a combination of NSAIDs with either colchicine or steroids.

    Non-steroidal anti-inflammatory drugs

    Attacks of gout are often treated with NSAID tablets, which can help with pain and reduce some of your inflammation. Ibuprofen, Naproxen and diclofenac are three NSAIDs you could be given.

    If youve been prescribed NSAIDs to treat an attack, you should start taking them as soon as you notice signs of one coming on. Your doctor may let you keep a supply so you can start taking them at the first signs of an attack.

    The earlier you start treatment, the better.

    NSAIDs arent suitable for everyone, so talk to your doctor about them first if you have any other conditions. They can also interact with other drugs, so make sure you talk to a doctor before starting on any new medication.

    Colchicine

    Colchicine isnt a painkiller, but can be very effective at reducing the inflammation caused by urate crystals.

    Colchicine tablets can cause diarrhoea or stomach aches.

    Steroids
