The hyperglycemia from corticosteroid therapy usually occurs in the first 6 weeks of therapy and is believed to be secondary to insulin resistance and increased hepatic gluconeogenesis24. Patients with type 1 diabetes (or with type 2 diabetes on insulin) who are receiving glucocorticoid therapy and whose fasting plasma glucose is lower than 13 mmol/L can be monitored in the oncology clinic in conjunction with their primary care physician; patients whose fasting plasma glucose is higher than 13 mmol/L should be referred to an endocrinologist or diabetologist, Use the lowest possible dose of dexamethasone.

May enhance secondary fungal or viral infections of the eye, Muscle pain or weakness, muscle wasting, pathologic long bone or vertebral compression fractures, atrophy of protein matrix of bone, aseptic necrosis of femoral or humeral heads. Some publications favour tapering until a physiologic dose equivalent to 20 mg of cortisol daily is achieved, which might be 0.25 mg dexamethasone daily18,19. National Library of Medicine This content is owned by the AAFP. Corticosteroids are used as adjuvant analgesics for pain in cancer patients and patients with neuropathic pain such as herpes zosterrelated neuropathy, spinal cord compression and pain following oral surgery. Pre-irradiation Evaluation and Management of Brain Metastases. Press 'Calculate' to view calculation results. Reduction of uric acid levels is key to avoiding gout flares. MDCalc loves calculator creators researchers who, through intelligent and often complex methods, discover tools that describe scientific facts that can then be applied in practice. Kane SP. Patients receiving urate-lowering medications should be treated concurrently with nonsteroidal anti-inflammatory drugs, colchicine, or low-dose corticosteroids to prevent flares. Patients with nerve compression pain or pain resulting from increased intracranial pressure showed a better response when compared with patients with other pain syndromes.31 Higher intravenous dosages of methylprednisolone, such as 125 mg per day, can be used for palliative therapy in patients with terminal cancer.32, Perioperative use of corticosteroids has been advocated to reduce pain and decrease edema and trismus following oral surgical procedures. The proximal arm muscles and neck may become involved as the myopathy progresses20. During radiation therapy, a tapering dose of dexamethasone, as clinically tolerated (to alleviate symptoms of cerebral edema), is prescribed, and the lowest effective dose is used. Gout is typically diagnosed using clinical criteria from the American College of Rheumatology. Similarly, because dexamethasone is metabolized by the p450 3A4 pathway common to many other drugs, there is potential for interaction with other medications, including rapid catabolism of dexamethasone. The search included expert consensus statements, clinical reviews, and clinical trials. Low-dose tests play major role in screening and initial assessment. Prednisone and methylprednisolone, which are intermediate-acting products, are four to five times more potent than hydrocortisone. Give 1 mg of Dexamethasone USP orally at 11:00 p.m. Potential use. [Available at: NCCN Clinical Practice Guidelines in Oncology: Central Nervous System Tumours. Dexamethasone is available as 0.5mg, 0.75 mg and 4 mg tablets. Patients should be observed during the taper for symptoms of increased intracranial pressure, and if such symptoms occur, the dexamethasone should be increased back to the previous dose in the tapering regimen (recommendation grade: C). Increased susceptibility to infections, masked symptoms of infections. The dose should be adjusted in patients with chronic kidney disease and when used with cytochrome P450 3A4 or P-glycoprotein inhibitors. As there are many changes in daily dosage, it would be advisable to write out the daily dosages on a calendar. All patients given high-dose dexamethasone (24 mg intravenously every 6 hours for 48 hours), then randomized to either 4 mg every 6 hours for 2 weeks radiotherapy tapering regimen (group 1), or no further dexamethasone (group 2), Steroid of choice, usually dexamethasone Dose range: 416 mg daily (mean: 14.6 mg daily).

Dosing is guided by the target serum uric acid level.9,22 In patients with chronic kidney disease, low initial doses are recommended with slow titration to achieve target uric acid levels.33 Dosages higher than 300 mg may be usedeven in those with renal impairmentas long as patients are closely monitored for adverse effects.9 Certain ethnic groups have a higher risk of a severe hypersensitivity skin reaction when starting allopurinol therapy. Use with extreme caution in patients with recent myocardial infarction because of an apparent association with left ventricular free-wall rupture.

The quality of the evidence was classified according to criteria used in other Canadian guidelines (Table ii), and the strength of the resulting recommendations from the Alberta Provincial cns Tumour Team were graded based on the evidence classifications10. Allopurinol, a xanthine oxidase inhibitor, is a first-line agent to prevent recurrent gout.9 In patients with gout and chronic kidney disease or congestive heart failure, allopurinol has the added benefit of preventing chronic disease progression.31,32 The starting dosage is 100 mg per day, and 300 mg per day is a common maintenance dosage. Abstract. A review by Messer et al.41 included 3064 corticosteroid-treated patients evaluated for peptic ulcers. In a study reporting the results of two consecutive randomized trials involving 96 patients with brain metastases, Vecht et al.3 compared 4-, 8-, and 16-mg daily oral doses of dexamethasone. Systemic corticosteroids have been used in the treatment of numerous medical conditions for approximately 50 years. Doses of over 300 mg daily should be taken in divided doses to help minimize any gastrointestinal adverse effects with maximum of 300 mg per dose. These produce inflammatory components such as cytokines, which lead to meningeal inflammation and increased intracranial pressure.46,47 Hence, reducing meningeal inflammation is thought to reduce central nervous system complications.48,49, Studies show that potent corticosteroids, such as dexamethasone, combined with appropriate antibiotics reduce the risk of acquired sensorineural deafness and the incidence of other neurologic sequelae in meningitis caused by Haemophilus influenzae.50 Corticosteroids were found to be more effective when administered simultaneously with antibiotics or 15 to 20 minutes before starting them.

This form of administration enables the patient to experience the therapeutic effects while side effects are minimized.3 This therapeutic alternative is only possible with the intermediate-acting corticosteroid agents (Table 1).1 Whenever possible, the goal of steroid therapy should be to maintain the lowest dosage that results in adequate clinical response and to discontinue therapy by tapering the drug when a patient's disease state allows (Table 3).13,5.
