Systemic corticosteroids can reactivate tuberculosis and should not be used in patients with a history of active tuberculosis, except when chemoprophylaxis is instituted concomitantly. The incidence or course of acute bacterial infection are probably minimally affected by inhaled triamcinolone. Application of topical corticosteroids to areas of infection, including tuberculosis of the skin, should be initiated or continued only if the appropriate antiinfective treatment is instituted. If the infection does not respond to the antimicrobial therapy, the concurrent use of the topical corticosteroid should be discontinued until the infection is controlled.

Most patients with pruritus benefit from several basic measures to lessen drying of skin, which can increase symptoms. Bathing should be limited to short, cool showers with soap applied only to intertriginous or oily skin areas. A mild moisturizing cream should be applied immediately after bathing. The patient's home should be humidified to at least 40 percent, especially during dry, cold winter months. Contact irritants, such as wool, fiberglass, and detergents, irritate most skin and can exacerbate symptoms, particularly in persons with sensitivity to these agents. 2 , 3 , 5 , 41 , 42

1 mg/kg IV every 8 to 12 hours for 1 to 5 days has been studied in premature and term neonates (combined n from 3 studies = 89, gestational age 23 to 40 weeks). An initial loading dose of 2 mg/kg IV was used in 1 retrospective study and another prospective, observational study used a higher maintenance dose of 3 to 6 mg/kg/day IV divided 2 to 4 times daily in a small number of patients (n = 5) with severe capillary leak syndrome and/or previous steroid treatment. In the largest prospective, randomized, placebo controlled study (n = 48, gestational age to weeks), patients receiving hydrocortisone 1 mg/kg IV every 8 hours for 5 days required significantly less vasopressor support (lower doses of dopamine and dobutamine, shorter duration of vasopressor therapy, and fewer patients requiring more than 1 vasopressor) compared to patients receiving placebo. The trend of the average mean arterial blood pressure (MAP) was also significantly higher in patients receiving hydrocortisone compared to patients receiving placebo.

Corticosteroids have been used as drug treatment for some time. Lewis Sarett of Merck & Co. was the first to synthesize cortisone, using a complicated 36-step process that started with deoxycholic acid, which was extracted from ox bile . [43] The low efficiency of converting deoxycholic acid into cortisone led to a cost of US $200 per gram. Russell Marker , at Syntex , discovered a much cheaper and more convenient starting material, diosgenin from wild Mexican yams . His conversion of diosgenin into progesterone by a four-step process now known as Marker degradation was an important step in mass production of all steroidal hormones, including cortisone and chemicals used in hormonal contraception . [44] In 1952, . Peterson and . Murray of Upjohn developed a process that used Rhizopus mold to oxidize progesterone into a compound that was readily converted to cortisone. [45] The ability to cheaply synthesize large quantities of cortisone from the diosgenin in yams resulted in a rapid drop in price to US $6 per gram, falling to $ per gram by 1980. Percy Julian's research also aided progress in the field. [46] The exact nature of cortisone's anti-inflammatory action remained a mystery for years after, however, until the leukocyte adhesion cascade and the role of phospholipase A2 in the production of prostaglandins and leukotrienes was fully understood in the early 1980s.
