One hundred male patients who presented with acute gouty arthritis were alternately assigned to 2 treatment groups. Seventy-six patients completed the study protocol, in which each
gout
attack during a 1-year period was treated. For each
gout
episode, 36 patients received a single intramuscular injection of 40 IU of
adrenocorticotropic hormone (ACTH)
, and 40 patients received oral indomethacin, 50 mg 4 times daily with meals, until the pain abated. The time interval until the pain was relieved, as well as any untoward effects, were recorded for each
gout
attack treated. Both groups were of similar age, and had similar values for intercritical serum uric acid, 24-hour urinary uric acid, and creatinine clearance (1 month after entry into the study). The mean interval (+/- SD) to relief of pain was significantly shorter for the ACTH group (3 +/- 1 hours) than for the indomethacin group (24 +/- 10 hours). No side effects were noted in the ACTH group. However, of the 40 patients receiving indomethacin, 22 had abdominal discomfort of dyspepsia, 15 had headaches, and 12 had difficulty with mentation. Single-dose parenteral ACTH appeared to be effective more rapidly and was associated with fewer side effects than oral indomethacin in the treatment of acute
gout
.

Serum
beta-endorphin
levels have been determined in patients with a wide variety of rheumatic disorders as well as a group of healthy men and women controls. Normal levels of endorphin have been found in patients with juvenile rheumatoid arthritis. Patients with rheumatoid arthritis, osteoarthritis, systemic lupus erythematosus,
gout
, ankylosing spondylitis, pseudogout and psoriatic arthritis have diminished levels of endorphins. Speculation is offered to explain these changes. Perturbations in endorphins are postulated to be part of the organism's protective mechanism in inflammatory arthritis.

The adrenal cortical hormone, cortisone, and the pituitary
adrenocorticotropic hormone (ACTH)
possess potent antirheumatic properties. Their administration produces strikingly beneficial effects on a number of rheumatic diseases including rheumatoid arthritis, rheumatoid (ankylosing) spondylitis, acute rheumatic fever, disseminated lupus erythematosus, periarteritis nodosa, psoriatic arthritis, dermatomyositis, and
gout
. In general the effects of these substances are temporary and they cause suppression rather than cure of the disease processes. Improvement is maintained usually only by continuing administration, and on hormonal withdrawal prompt or fairly prompt relapse of the disease manifestations ensues. In addition to their antirheumatic effects cortisone and ACTH influence a wide variety of physiologic functions. Administration of them therefore may produce a number of metabolic and clinical changes, some of which are not advantageous from a therapeutic standpoint. Adverse side-reactions are more liable to occur when large doses of the hormones are given for prolonged periods; such reactions appear to be reversible and disappear when administration of the hormones is stopped. With cortisone, comparatively few untoward signs develop when smaller amounts are administered continuously even for periods of months. Greater clinical experience is needed before optimal doses and schedules of administration are finally determined. It appears that some severe cases, many moderately severe cases, and most moderate and mild cases of rheumatoid arthritis may be adequately controlled with smaller "maintenance" doses of cortisone ranging from 32 to 65 mg. a day, providing larger doses to suppress the disease manifestations are employed initially. Neither cortisone nor ACTH should be considered as a therapeutic agent for general use until more information regarding their physiologic activities and the consequences of prolonged or repeated administration of them are available. Until the potential dangers of these hormones can be determined precisely, the use of them should be considered as an investigative procedure.

There are three stages in the management of
gout
: (i) treating the acute attack; (ii) lowering excess stores of uric acid to prevent flares of gouty arthritis and to prevent tissue deposition of urate; and (iii) providing prophylaxis to prevent acute flares. It is important to distinguish between therapy to reduce acute inflammation in acute
gout
and therapy to manage hyperuricaemia in patients with chronic gouty arthritis. During the acute gouty attack nonpharmacological treatments such as topical ice and rest of the inflamed joint are useful. NSAIDs are the preferred treatment in acute
gout
. The most important determinant of therapeutic success is not which NSAID is chosen, but rather how soon NSAID therapy is initiated. Other treatments include oral and intravenous colchicine, intra-articular and systemic corticosteroids, and intramuscular
corticotropin
. Optimal treatment of chronic
gout
requires long-standing reduction in serum uric acid. The urate-lowering drugs used to treat chronic
gout
are the uricosuric drugs, the uricostatic drugs, which are xanthine oxidase inhibitors, and the uricolytic drugs. Xanthine oxidase inhibitors such as allopurinol, oxipurinol and febuxastat should be used as first-line treatment in patients with renal calculi, renal insufficiency, concomitant diuretic therapy and ciclosporin (cyclosporine) therapy, and urate overproduction. Uricosuric drugs include probenecid, benzbromarone, micronised fenofibrate and losartan. They are the urate-lowering drugs of choice in allopurinol-allergic patients and underexcretors with normal renal function and no history of urolithiasis. The use of recombinant urate oxidase in patients with chronic
gout
is limited by the need for parenteral administration, the potential antigenicity and production of anti-urate oxidase antibodies, and declining efficacy. The effectiveness of colchicine prophylaxis as an isolated therapy is still to be confirmed by placebo-controlled trials. Another issue is prophylaxis with NSAIDs. There are no comparative studies with colchicine.

Gout
, a common inflammatory arthritis, can be diagnosed with absolute certainty.
Gout
results from the body's reaction to urate crystals deposited in tissues, and this pathophysiology is well understood. If used appropriately, available therapies can be entirely effective in not only treating the symptoms of
gout
, but also in eliminating the excess urate from the body, thereby eradicating the disease. Because of these facts, management of patients with
gout
should be successful. However, management of
gout
is particularly challenging in the elderly, even though the principles of management are the same for all age groups. The purpose of this article is to review these principles and discuss them as they pertain to the elderly. The classic
gout
attack is acute in onset, extremely painful and associated with marked swelling, warmth, erythema and tenderness of a single joint. However, the diagnosis of
gout
may be challenging in the elderly because atypical presentations are more common in this group. Treatment of acute
gout
involves the use of NSAIDs, colchicine, corticosteroids or
corticotropin
(adrenocorticotropic hormone). Unfortunately, co-morbid conditions such as chronic kidney disease, peptic ulcer disease and congestive heart failure may make the use of these agents dangerous or contraindicated. Thus, it is important to try to treat an acute flare of
gout
at the earliest sign, because the sooner treatment is initiated, the faster the inflammation will resolve. Urate-lowering agents include allopurinol and uricosuric agents. These also must be used judiciously in the elderly. However, if used at the lowest dose that maintains the serum urate level below 5.0-6.0 mg/dL, the excess urate in the body will be eliminated, acute flares will no longer occur and tophi will resolve.
Gout
is often seen in association with hypertension, excessive alcohol consumption, obesity and hypertriglyceridaemia. These conditions and the medications used to treat them may contribute to the hyperuricaemia. Treating these conditions and using medications that do not promote hyperuricaemia will aid in the management of
gout
. Despite the challenges that often complicate the management of
gout
in the elderly, an understanding of the pathophysiology of the disease and both the indications and limitations of the medications used should allow successful treatment.

Most of the drugs prescribed to treat acute gouty attacks were used before the introduction of modern clinical trials. Thus, there are few well-designed studies available to evaluate these drugs. Nevertheless, worldwide clinical experience supports the use of most nonsteroidal anti-inflammatory drugs (NSAIDs), colchicine and corticosteroids in the treatment of acute
gout
. Colchicine has been widely used but toxicity, especially gastrointestinal adverse effects, are a major concern. Therapeutic regimens involving hourly or 2-hourly administration were based on the short initial half-life of colchicine in plasma. Other therapy schedules, such as early 8-hourly administration, may be equally effective and have fewer adverse effects. Unfortunately, comparative studies to investigate this have not been performed. Colchicine should not be prescribed to patients with either severe renal insufficiency or combined hepatic-renal insufficiency. Doses should be halved in patients with moderate renal function impairment. NSAIDs are the most widely prescribed drugs in the treatment of acute
gout
. Few comparative data are available, but any of the most potent NSAIDs are probably useful in the control of pain and inflammatory signs of acute gouty arthritis. Pharmacokinetic properties should be taken into account when selecting an NSAID for the treatment of
gout
, as rapid absorption and a short half-life may help to avoid accumulation in patients with subclinical renal function impairment. Comorbidities should always be kept in mind when prescribing NSAIDs. Patients with previous or recent gastrointestinal bleeding, those receiving anticoagulant therapy or with haemorrhage diathesis, and those with renal insufficiency are at risk of developing severe adverse effects from NSAID administration. Corticosteroids are probably a reasonable choice for patients in whom colchicine and NSAIDs may be hazardous or for those with a history of previous intolerance to these drugs. Few trials using prednisone, prednisolone or triamcinolone acetonide are available, and dosages are prescribed following empirical data.
Corticotropin
has also been used to treat acute
gout
. Although it has been proven to be as effective as other corticosteroids or indomethacin, the need for multiple doses, parenteral administration and the high cost are major limitations for its use. Currently, the choice of a drug for the treatment of acute
gout
will depend on the balance between its efficacy and the potential adverse effects in a particular patient.

It is important to distinguish between therapy used to reduce acute inflammation in
gout
and therapy used to manage hyperuricaemia in patients with chronic gouty arthritis. This article discusses treatments for acute
gout
, emphasizing the use of corticotrophin (adrenocorticotropic hormone; ACTH) and the evidence on which we base our treatment of acute
gout
. There are no formal guidelines for the treatment of acute
gout
and only a few randomized controlled trials have been conducted to evaluate the efficacy of the various treatments for acute
gout
. The options available for the treatment of acute attacks of
gout
are NSAIDs, colchicine, corticosteroids,
corticotropin
and intra-articular corticosteroids. Most rheumatologists practicing in the US use combination therapy to treat acute
gout
, a practice that merits study. In a patient without complications, NSAIDs are the preferred therapy. The most important determinant of therapeutic success is not which NSAID is chosen, but rather how soon NSAID therapy is initiated. Exciting new research shows that
corticotropin
acts peripherally by activation of the melanocortin type 3 receptor, and this could be responsible, at least in part, for its efficacy in acute
gout
. Hopefully, this will lead to renewed interest in
corticotropin
as a treatment for acute
gout
.

There has been an increase in the incidence and prevalence of
gout
in the past several decades. A distinction needs to be made between the treatment of
gout
as an acute inflammatory disease and the lowering of the serum urate (SU) levels into a normal range. Treating acute
gout
attacks alone is not sufficient to prevent the disease from progressing. When treating
gout
one needs to treat acute attacks, and lower excess stores of uric acid to achieve dissolution of monosodium urate crystals through a long-term reduction of SU concentrations far beyond the threshold for saturation of urate and provide prophylaxis to prevent acute flares. The options available for the treatment of acute
gout
are NSAIDs, colchicine, corticosteroids,
adrenocorticotropic hormone (ACTH)
and intra-articular corticosteroids. The most important determinant of therapeutic success is not which anti-inflammatory agent is chosen, but rather how soon therapy is initiated and that the dose be appropriate. Prophylaxis should be considered an adjunct, rather than an alternative, to long-term urate-lowering therapy. For purposes of maintaining patient adherence to urate-lowering therapy, there is interest in improving prophylaxis of such treatment-induced attacks. The optimal agent, dose and duration for
gout
prophylaxis are unknown and require further investigation. The importance of long-term management of
gout
is the reduction and maintenance of SU in a goal range, usually defined as less than 6.0 mg/dL. Allopurinol and benzbromarone remain the cornerstone drugs for reducing SU levels lower than the saturation threshold to dissolve urate deposits effectively. Febuxostat and pegloticase help to optimize control of SU levels, especially in those patients with the most severe
gout
. Other agents, such as fenofibrate and losartan may be helpful as adjuvant drugs. Treatment for
gout
has advanced little in the last 40 years, until recently. The recent development of new therapeutic options promises to provide much needed alternatives for the many patients with
gout
who are intolerant of or refractory to available therapies. It is important to note that inappropriate use of medications as opposed to an apparent refractoriness to available therapies is not uncommon.
