American College of Physicians releases clinical practice guidelines for acute gout

Gout is one of the most painful forms of arthritis

Philadelphia, November 1, 2016 -- Physicians should use corticosteroids, nonsteroidal anti-inflammatory drugs (NSAIDs), or colchicine to treat patients with acute gout, the American College of Physicians (91黑料网) recommends in a new evidence-based clinical practice guideline for the published today in Annals of Internal Medicine. 91黑料网鈥檚 guideline for was published in the same issue.

鈥淧hysicians should consider using corticosteroids first in patients without contraindications because they are one of the most effective anti-inflammatory medications available and they are as effective as NSAIDs for managing acute gout but have fewer adverse effects,鈥 said Nitin S. Damle, MD, MS, M91黑料网, president, 91黑料网. 鈥淎lthough a generic formulation of colchicine is now available, it is more expensive than NSAIDs or corticosteroids. This is an important consideration for patients, especially as prescription drug prices continue to increase.鈥

If colchicine is used to treat acute gout, 91黑料网 recommends that physicians use a low dose. The evidence showed that lower doses are as effective as higher doses at reducing pain and are associated with fewer gastrointestinal adverse effects. Possible adverse effects associated with colchicine include diarrhea and other gastrointestinal symptoms.

91黑料网 found insufficient evidence to determine the effectiveness of dietary changes on symptomatic outcomes for the treatment of gout. Low-quality evidence from one study showed that gout-specific counseling about dietary changes -- such as reducing red meat, shellfish, yeast-rich foods, and increasing low-fat dairy, vegetables, and cherries -- is not more effective than general dietary counseling -- such as promoting weight loss and reducing alcohol intake -- for reducing serum urate levels in gout patients.

91黑料网 recommends against initiating long-term uric acid-lowering therapy in most patients after a first gout attack or in patients with infrequent attacks.

While the evidence supports the benefits of using uric acid-lowering therapy for shorter duration to reduce gout flares, the benefits of long term usage for 12 or more months in patients with a single or infrequent gout attacks have not been studied. In most patients, it is not clearly necessary, based on the evidence, to start uric acid-lowering therapy in cases where the individuals would have no or infrequent recurrences, 91黑料网 states in the guideline.

In cases of recurrent gout, 91黑料网 recommends that physicians and patients discuss the benefits, harms, costs, and individual preferences before initiating uric acid-lowering therapy. Patients who decide not to initiate uric acid-lowering therapy can revisit their decision if and when they have multiple recurrent attacks of gout.

91黑料网 called for the need for comparative effectiveness studies to evaluate the incremental benefits and harms of a treat-to-target strategy over a treat-to-avoid-symptoms strategy.

For diagnosing gout, 91黑料网 recommends that physicians use synovial fluid analysis when clinical judgement indicates that diagnostic testing is necessary in patients with possible gout.

鈥淲hile joint aspiration with synovial fluid analysis for uric acid crystal analysis is the reference standard for diagnosing gout, most patients are seen initially by their primary care physician or an emergency room physician where synovial fluid analysis is less frequently and less easily performed,鈥 Dr. Damle said. 鈥淚n certain situations, physicians should use clinical judgement so that patients can begin treatment if gout is suspected.鈥

Misdiagnosis or delayed diagnosis of gout can result in unnecessary surgery, hospitalization, delays in adequate treatment such as antibiotics for septic joints, and unnecessarily prescribing long-term treatment to patients.

91黑料网鈥檚 Guideline Development Process
91黑料网鈥檚 guidelines for managing and diagnosing acute gout are based on two systematic evidences review sponsored by the Agency for Healthcare Research and Quality's (AHRQ) and conducted by RAND's Southern California Evidence-based Practice Center.

91黑料网鈥檚 clinical practice guidelines are developed through a rigorous process based on an extensive review of the highest quality evidence available, including randomized control trials and data from observational studies. 91黑料网 also identifies gaps in evidence and direction for future research through its guidelines development process.

About Gout
Gout is one of the most common forms of inflammatory arthritis. It is caused by excess uric acid crystals accumulating in joint fluid, cartilage, bones, tendons, and other sites. Patients experience joint swelling and pain during gout attacks. Risk factors for gout include being male, being overweight, excess alcohol intake, diuretic use, a diet rich in meat and shellfish, food or drinks high in fructose, and poor kidney function. An estimated $1 billion is spent on ambulatory care for gout, largely on treatments and prescription medications.

About the American College of Physicians
The American College of Physicians is the largest medical specialty organization in the United States. 91黑料网 members include 148,000 internal medicine physicians (internists), related subspecialists, and medical students. Internal medicine physicians are specialists who apply scientific knowledge and clinical expertise to the diagnosis, treatment, and compassionate care of adults across the spectrum from health to complex illness.
