Extensions of this concept have utilized enamine hydrolysis (171, X = R N) and the quenching of the enolate anion (171, X = O ) e.g. ref. 353). a,(i-Un-saturated ketones are usually more stable than their p,y counterparts, but there are notable exceptions to this, and in such cases the deconjugated ketone may be isolated from the equilibrated system. For example, retro steroids (9, 10a) have a large proportion of A -3-ketone at equilibrium, and 17-ketones yield the more stable A -system on treatment with acid. ... 

Systemic corticosteroids, administered orally or by depot injection, are considered last-resort options when all other treatments for SAR are inadequate. Systemic steroids may be used to control rhinitis symptoms in patients with severe PAR or nasal polyposis. Data comparing oral and parenteral steroid therapy are lacking however, oral therapy is preferred due to its low cost... 

A first open, uncontrolled study [46], performed in 12 patients with active IBD refractory to standard treatment who all had positive stool culture, suggested that adding rifaximin (800 mg daily) could be beneficial. A further small but controlled investigation performed in our unit [47] evaluated the efficacy and systemic absorption of rifaximin in patients with moderately to severely active UC refractory to steroid treatment. Patients were eligible if they had no response to intravenous corticosteroid therapy (methylprednisolone 1 mg/kg/day) after 7-10 days. Twenty-eight patients were randomized to receive rifaximin 400 mg b.i.d. or placebo for 10 days as an add-on... 

Steroids are frequently used for the treatment of active Crohn s disease, particularly with more severe presentations, or in those patients unresponsive to aminosalicylates. Budesonide is a viable first-line option for patients with mild to moderate ileal or right-sided disease. Systemic steroids induce remission in up to 70% of patients and should be reserved for patients with moderate to severe disease who have failed aminosalicylates or budesonide. 

Stabilize the patient s asthma before treatment is started. Initially, use aerosol concurrently with usual maintenance dose of systemic steroid. After approximately 1 week, start gradual withdrawal of the systemic steroid by reducing the daily or alternate daily dose. Make the next reduction after 1 to 2 weeks, depending on response. Generally, these decrements should not exceed 25% of the prednisone dose or its equivalent. A slow rate of withdrawal cannot be overemphasized. 

Infections Localized fungal infections with Candida albicans or Aspergillus niger have occurred in the mouth, pharynx, and occasionally in the larynx. The incidence of clinically apparent infection is low, and may require treatment with appropriate antifungal therapy or discontinuance of aerosol steroid treatment. Use inhaled corticosteroids with caution, if at all, in patients with active or quiescent tuberculous infection of the respiratory tract, untreated systemic fungal, bacterial, parasitic or... 

Seizures Bupropion is associated with a dose-related risk of seizures. Discontinue bupropion and do not restart in patients who experience a seizure while on treatment. Use extreme caution when bupropion is administered to patients with a history of seizure, cranial trauma, or other predisposition(s) toward seizure, or prescribed with other agents (eg, antipsychotics, other antidepressants, theophylline, systemic steroids) that lower seizure threshold. 

Concomitant medications - Many medications (eg, antipsychotics, antidepressants, theophylline, systemic steroids) and treatment regimens (eg, abrupt discontinuation of benzodiazepines) are known to lower seizure threshold. 

Inhaled glucocorticoid preparations, such as be-clomethasone dipropionate and betamethasone valerate, provide an effective alternative to systemic steroids in the treatment of chronic asthma, with lesser side effects than oral or parenteral glucocorticoids (see Chapter 39). In fact, inhaled glucocorticoids have become a mainstay of asthma therapy. Inhalation delivers the agent directly to the target site in relatively low doses, with the potential for more frequent administration. Moreover, inhaled glucocorticoids are metabolized in the lung before they are absorbed, which reduces their systemic effects. However, even modest doses of... 

The first inhaled glucocorticoid, beclomethasone dipropionate, revolutionized asthma therapy, when it was found that topical delivery to the lung resulted in reduced systemic side-effects (adrenal suppression, oseteoporosis and growth inhibition) typically seen with oral steroid treatments. Interestingly, a further reduction in systemic exposure was achieved with the introduction of fluticasone propionate (1). The evolution of this drug stemmed from observations with the steroid 17-carboxylates that showed that these esters were active topically when esterified, while the parent acids were inactive. Thus it was realized that enzymatic hydrolysis of the ester would lead to systemic deactivation. SAR studies led to a series of carbothioates, which were very active in vivo when topically applied to rodents, but were inactive after oral administration. It was shown that fluticasone propionate (1) underwent first pass metabolism in the liver to the corresponding inactive 173-carboxylic acid (la) (Scheme 1). This observation was... 

In patients allergic to mites, the duration of the treatment seems to be crucial a long-lasting treatment with a high dose of allergen may provide positive results [20] (fig. 1). It is important to notice that SLIT could exert its effects not only on rhinitis but also on asthma symptoms. The results from recent studies showed that there is a clear-cut reduction of the clinical symptom score [20, 23, 24], the days with asthma symptoms [25], as well as the use of (32-agonists [21, 25], and the use of systemic steroids [32],... 

Sulfasalazine is more effective when Crohn s disease involves the colon. Mesalamine derivatives (such as Pentasa or Asacol) that release mesalamine in the small bowel may be more effective than sulfasalazine for deal involvement. Steroids are frequently used for the treatment of active Crohn s disease, particularly with more severe presentations, or in those patients unresponsive to aminosalicylates. Budesonide is a viable first-line option for patients with mdd to moderate deal or right-sided disease. Systemic steroids induce remission in up to 70% of patients and should be reserved for patients with moderate to severe disease who have faded aminosahcylates or budesonide. Metronidazole (given orally up to 20 mg/kg/day) may be useful in some patients with Crohn s disease, particularly in patients with colonic or deocolonic involvement or those with perineal disease. The combination of metronidazole with ciprofloxacin is efficacious in some patients. 

The available steroids vary in their ability to suppress the inflammatory response.Table 12-2 shows the approximate equivalent doses of systemic steroids in current use. Methylprednisolone is commercially available in a package for programmed delivery of oral steroid tapered over 6 days of therapy.This formulation (Medrol DosePak) is highly convenient for short-term treatment and helps to ensure patient compliance in the tapering schedule. 

Cat-scratch disease is caused by Bartonella henselae or B. quintana, which are gram-negative bacteria. It is transmitted through a cat scratch, bite, or lick and may cause a neuroretinitis with variable effect on visual acuity. The Bartonella species organisms are susceptible to a number of antibiotics. Systemic steroids can be used as an adjimctive treatment. 

Therapy for SEE is both complex and, in many instances, disappointing for both patient and practitioner. Management of the systemic signs and symptoms may not improve the ocular manifestations of the disease. The most common therapy for the arthritic and cardiac complications is NSAID use. Hydroxychloroquine and chloroquine are particularly effective in treating the discoid rash associated with the disease. In some cases oral steroids are used either alone or in combination with other immunosuppressive agents. Methotrexate can effectively reduce the need for systemic steroids in the treatment of mild to moderate SEE. Cyclophosphamide and... 

A comprehensive review of systems, physical examination, ocular examination, and laboratory testing with a multidisciplinary approach to determine the etiology of IK is essential. Treatment should be aimed at addressing any underlying systemic disease and may involve the use of systemic steroids or immunosuppressive drug therapy depending on the cause. 

A 62-year-old diabetic man on stable oral medication with glibenclamide, metformin, Zestoretic (lisino-pril + hydrochlorothiazide), gemfibrozil, and aspirin developed febrile generalized pustular eruptions after 44 days of therapy with oral terbinafine 250 mg/day (50). Withdrawal of terbinafine and symptomatic treatment with hydrotherapy and topical and systemic steroids resulted in complete resolution of fever and pustulosis within 4 days. The erythematous component responded more slowly, and mildly pruritic erythematous plaques persisted for more than 40 days. 

Corticosteroids — Beclomethasone dipropionate (17) aerosol has been tested extensively clinically. It is used prophylactically (400 fig per day), not therapeutically, in the treatment of chronic asthma, particularly in children.52 An evaluation of the drug has been published.53 One of the most important clinical advantages is that 1 7 effectively can replace oral corticosteroids in steroid-dependent patients and avoid many of the adverse effects of adrenal suppression.52,54 Most patients with impaired adrenal function due to oral corticosteroids show recovery of adrenal function within 6 months.55 The combination of 17 and disodium cromoglycate (DSCG) showed no additive therapeutic effects.5 Flunisolide (18), when administered as a nasal spray for 4 weeks during the hay fever season in 51 patients, showed significant symptomatic improvement with no systemic steroid effects observed.57...
