Some patients with diabetes mellitus are at increased risk for the development of hyperkalemia. Included in this group are patients with glucose-induced hyperkalemia who may have renal insufficiency, hyporeninemic hypoaldosteronism, or other impediments to the release or action of aldosterone. In an unusual demonstration of this abnormality, two patients with diabetes, who form the basis of our report, became markedly hyperglycemic and hyperkalemic after cosyntropin administration. To our knowledge, this complication of adrenocorticotropic hormone (ACTH) stimulation testing has not been previously reported. It should therefore be emphasized that the use of cosyntropin as a diagnostic agent can provoke severe hyperglycemia and hyperkalemia in a susceptible subgroup of patients with diabetes mellitus.

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.

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.
