For proper use of systemic GCS, a basic knowledge of the normal HPA axis, as well as knowledge of the pharmacology, clinical usage guidelines, and adverse reactions of these agents is imperative. Both short-term (acute) and long-term side effects should be well known by the physician. The pros and cons of oral and parenteral therapy for various disorders and in various situations should be recognized. For long-term therapy, an intermediate-acting agent such as prednisone in single, early morning doses is most commonly used to minimize suppression of the HPA axis. Alternate-morning doses produce even less suppression if the disease process will respond. A through patient history, including general medical history and medications the patient is taking, is important to anticipate any potential problems. Weight and blood pressure should be checked initially and every 1 to 3 months thereafter. Blood glucose, electrolytes, and lipid studies, including triglycerides, should be done approximately every 6 months. An ophthalmology examination should be performed every year, and stool examination for occult blood and chest radiography can be obtained as indicated. Bone density studies might be necessary in patients who are at high risk for osteoporosis. Specific acute situations may dictate other studies. The patient on long-term GCS should be kept as active as possible, as mild-to-moderate exercise helps prevent certain side effects, such as osteoporosis. The dose of oral GCS is best given with food to prevent gastrointestinal irritation, and agents to decrease gastric acidity might be needed in certain situations. Exposure to infections should be prevented, where possible, and treatment initiated at the first sign of systemic or cutaneous infection. Pain should be evaluated early, especially abdominal pain or bone pain; MRI is indicated if aseptic necrosis of bone is suspected. Both trauma and severe sun exposure should be avoided. Consultation with other specialists is strongly recommended when the situation dictates. Diet is one of the most important strategies to minimize side effects from long-term GCS therapy. Vegetable protein should be increased in the diet, and fats and carbohydrates limited. Adequate calcium is imperative, and calcium supplementation is recommended for high-risk osteoporosis patients. Small amounts of vitamin D may be necessary to increase absorption of calcium. Restriction of sodium is also important, as is maintainance of dietary potassium. Supplemental potassium may be necessary in some patients, and a thiazide diuretic might be useful in patients with hypertension, edema, or osteoporosis. Vitamin C can be given to promote wound healing. A good doctor-patient relationship is important in managing the patient on long-term GCS. The patient must return for regular visits and be encouraged to promptly report any adverse reactions to the physician. If these criteria are maintained and the strategies noted previously are followed, problems from long-term therapy with GCS will be minimized.

Although dermatology now has the most extensive group of systemic medications available for the treatment of skin diseases at any time, GCSs remain the most important agents for managing inflammatory disorders. It is important that the dermatologist have a broad knowledge of guidelines for clinical use, pharmacology, and adverse effects of these drugs. Acute and chronic side reactions should be well recognized. An understanding of the HPA axis and reasons for administering GCSs in different ways is of great value. A good medical history should be taken on any patient treated with GCSs, including knowledge of conditions that would make GCSs inadvisable and other concomitant systemic medications that might produce drug interactions. During the course of therapy, physical examination should include all systems pertinent to side effects caused by these agents, including frequent evaluations of weight and blood pressure. Blood chemistries should be performed on a regular basis, including glucose, electrolytes, and serum lipids. Osteoporosis is one of the most significant adverse affects to be evaluated, with bone mineral density studies recommended on an annual basis for persons continuing on GCS therapy. If hip or other joint pain develops, MR imaging is the most specific and sensitive radiologic examination for evaluating the possibility of osteonecrosis. An ophthalmology examination should be performed every 6 to 12 months to detect early cataract or glaucoma development. Any early signs of infection should be evaluated by appropriate smears, wet preparations, and cultures. Many other studies, including gastrointestinal and pulmonary examinations, may be dictated by specific acute situations. It is important to begin early prevention of the bone loss that occurs with GCS-induced osteoporosis. The 1996 guidelines of the American College of Rheumatology, including adequate calcium and vitamin D intake, should be followed. Hormonal replacement, a bisphosphonate, calcitonin, or a thiazide diuretic may be indicated. Restriction of sodium in the diet is important, as well as adequate potassium intake. The diet should be low in saturated fat and calories and should be high in vegetable protein. Because osteoporosis is so prevalent with GCSs, keeping the patient as active as possible with mild-to-moderate exercise is important. Whenever possible, exposure to persons with infectious processes should be avoided, and proper treatment should be instituted at the initial signs of systemic or cutaneous infection. Oral doses of GCSs are best taken with food to prevent gastrointestinal irritation, and agents for gastric acidity occasionally may be indicated. Significant trauma should be prevented, as should severe exposure to the sun. Many situations may call for consultation with other medical or surgical subspecialists. The patient must be aware of the importance of regular physician evaluations and reporting of any adverse effects while on long-term GCSs. A good relationship and understanding between the patient and physician are vital in minimizing potential problems from these agents. If the dermatologist maintains the proper guidelines of care, patients on GCSs have the highest benefits and lowest risks possible.
