There is often angst among treating physicians around dose escalation of xanthine oxidase inhibitors in CKD patients, especially allopurinol, due to the risk of hypersensitivity reactions. Indeed, the increased risk for allopurinol hypersensitivity syndrome in CKD patients was first described over three decades ago by faculty at the very VA hospital where I was supervising that clinic. That article in 1984 by Hande et al suggested that urate levels may be controlled in CKD patients with lower doses of allopurinol than those needed among the general population and that use of “standard” dose may associate with increased risk of AHS. That line of inquiry led to changes to the package insert – and to changes in the practice patterns of physicians – that continue to contribute to the undertreatment of hyperuricemia. That recommended dosing strategy has never been shown to reduce the risk of adverse events, and as Vargas-Santos and Neogi point out, leads to chronic undertreatment of hyperuricemia.

Are eggs bad for gout?

Eggs are a good protein source for people with gout, because eggs are naturally low in purines.

Although the treatment of early use of low-dose colchicine is proposed, it is still unclear whether the early use of low-dose colchicine is superior to NSAID. Further, some studies found that more than 90% of patients had at least one contraindication to NSAIDs and that about one-third of patients prescribed colchicine had at least one major contraindication. Therefore, the evidence of the optimal drug therapy for acute episodes of gout is unidentified. Few data is published in the literature regarding refractory gout.

"The guideline is a directive based upon the best evidence," he said. "If there is no strong evidence that answers the clinical question, then maybe the guideline is not the place to find every answer." Dr. Fields agreed and noted that the decisions that physicians must make in their day-to-day practice cannot rely solely on the highest level of evidence from randomized controlled trials, particularly when those trials have not yet been conducted. He added that it's critical for physicians to know the quality of the evidence they are using to make clinical decisions. "However, we need to use all available evidence, along with expert opinion, to achieve optimal patient outcomes," he said.

ACR guidelines recommend that once palpable tophi and all acute and chronic gout symptoms have resolved, urate-lowering therapy should be continued indefinitely, if it is well-tolerated and not burdensome. NSAIDs are the drugs of choice in most patients with acute gout who do not have underlying health problems. Although indomethacin is the NSAID traditionally chosen for acute gout, most of the other NSAIDs can be used as well. Do not use aspirin, because it can alter uric acid levels and potentially prolong and intensify an acute attack.

Diagnosis Of Gout

Once a rheumatologist has diagnosed and effectively treated your gout, a primary care provider can usually track your condition and help you manage your gout. A medical doctor diagnoses gout by assessing your symptoms and the results of your physical examination, X-rays, and lab tests. Gout can only be diagnosed during a flare when a joint is hot, swollen, and painful and when a lab test finds uric acid crystals in the affected joint. Adopting healthy lifestyle habits is a key part of an effective gout treatment plan. Eat a healthy diet, avoid or limit high-purine foods, do regular exercise and lose excess weight to lower your risk of repeated gout attacks.

Once the target uric acid level has been achieved and maintained for 6 months, discontinue colchicine prophylaxis, unless the patient has 1 or more tophi on clinical exam. Urinary excretion amounting to less than 800 mg per 24-hour period on an unrestricted diet is considered underexcretion. Underexcreting patients are candidates for uricosuric therapy with probenecid. The dosage is increased at monthly intervals until the uric acid level is lowered to target.

Late in gout, if untreated, multiple joints can be involved, including the fingers and wrists. The shoulder joint is very rarely involved by gout and the same is true of the hip. In mammals other than man and the great apes, the enzyme uricase breaks uric acid into the more soluble allantoin, which can be more easily excreted in the urine. Humans, lacking this enzyme, run higher levels of uric acid and are thus subject to gout. Uric acid is a produced as part of the body’s metabolism of purines, which are produced as the body breaks down any of the many purine-containing substances, including nucleic acids from our diet or from the breakdown of our own cells. These are periods of time between acute attacks, during which a person feels normal but is at risk for recurrence of acute attacks.

Potential side effects include kidney stones, anemia and joint pain. Gout is a disorder of purine metabolism, and occurs when its final metabolite, uric acid, crystallizes in the form of monosodium urate, precipitating and forming deposits in joints, on tendons, and in the surrounding tissues. Microscopic tophi may be walled off by a ring of proteins, which blocks interaction of the crystals with cells and therefore avoids inflammation. Naked crystals may break out of walled-off tophi due to minor physical damage to the joint, medical or surgical stress, or rapid changes in uric acid levels. When they break through the tophi, they trigger a local immune-mediated inflammatory reaction in macrophages, which is initiated by the NLRP3 inflammasome protein complex.

If your pain isn't too bad, try cold packs or compresses on the joint to lower inflammation and soothe the ache. Wrap ice in a thin towel and apply it to the joint for up to 20 minutes several times a day. Do not apply ice to your hands or feet if you have nerve problems from diabetes or other causes.

As the disease progresses, gout becomes more aggressive in patients who develop symptoms before the age of 30, and whose baseline serum uric acid level is greater than 9.0 milligrams per deciliter (mg/dL). If caught and treated early, people with gout can live a relatively normal life. Some patients do not respond to treatment because they fail to follow protocols, have alcoholism, or are undertreated by physicians. In order to assess the best treatment in the normouricemic and refractory attack, it is necessary to consider the pathophysiology of gout. The initial phase is the formation of MSU crystals in a synovial fluid supersaturated with MSU . Next step is the amplification phase, in which there is activation of adhesion proteins and leukocyte recruitment to the synovial tissue by IL-1, opsonization of MSU crystals by IgG and complement.
