Superpotent topical corticosteroids (CS) have been demonstrated to improve bullous pemphigoid (BP) patients' survival. We assessed whether a mild regimen using lower doses of topical CS and a shorter duration could improve the outcome of BP patients even more. Three-hundred and twelve BP patients were included in a multicenter randomized controlled trial and stratified depending on the extent of BP as moderate (n=134) or extensive (n=178). Patients were randomly assigned to the standard regimen (clobetasol propionate cream, 40 g per day initially, with CS tapering over 12 months) or the mild regimen (10-30 g per day), with CS tapering over 4 months. A noninferior rate of BP control was obtained with the mild regimen 156/159 (98%) as compared with the standard regimen 150/150 (100%; P=0.005). Event-free survival, that is, the combined outcome of deaths and life-threatening adverse events did not differ between the two treatment groups (P=0.77). However, upon adjusting through the Cox model for age and Karnofsky score, a strong beneficial effect of the mild regimen was observed in patients with moderate BP, with an almost twofold decrease in the risk of death or life-threatening adverse events relative to the standard regimen (hazard ratio=0.54; 95% confidence interval, 0.30-0.97; P=0.039). This mild regimen allows a 70% reduction of the cumulative doses of CS and improves BP patients' outcome. Nasal polyposis is not a life-threatening disorder but has a great impact on the quality of life. Steroids constitute the first line of treatment of nasal polyps. The aims of this study were to evaluate the quality of life in nasal polyp patients after: (1) a short course of oral steroids; and (2) a long-term treatment with intranasal steroids.
                Patients with severe nasal polyps received either oral prednisone (n = 60) or no steroid treatment (control group, n = 18) for 2 weeks. Patients treated with steroids were also followed-up and evaluated after 12, 24, and 48 additional weeks with intranasal budesonide treatment.
                Patients with nasal polyps showed worse scores on all SF-36 domains, except for physical functioning, compared to the Spanish general population. After two weeks, patients treated with oral prednisone demonstrated a significant improvement (p < 0.05) in all impaired QoL domains compared to both control group and baseline. The mental component summary (51.0 +/- 1.2, p < 0.05) and physical component summary (51.0 +/- 0.9, p < 0.05) were improved compared to both control group and baseline. The improvement of all SF-36 domains was sustained by intranasal budesonida (p < 0.05) after 12, 24, and 48 weeks. Nasal obstruction, sense of smell, and polyp size also improved after both the oral short course and the intranasal long-term steroids treatment (p < 0.05).
                These results suggest that the treatment with a short-course of oral steroids improves the quality of life of patients with severe nasal polyps and that this effect is maintained by a long-term treatment with intranasal steroids. Recent studies suggested that administration of corticosteroids may improve clinical outcomes in patients with severe pneumonia.
                The aim of this study was to assess the effectiveness of corticosteroids as an adjunctive therapy in community-acquired pneumonia (CAP) requiring hospitalization.
                An open label, prospective, randomized control study was conducted from September 2003 to February 2004 in a community general hospital in Japan.
                Thirty-one adult CAP patients who required hospitalization were enrolled.
                Fifteen patients received 40 mg of prednisolone intravenously for 3 days (steroid group). Sixteen patients did not receive prednisolone (control group). Both groups were also evaluated for their adrenal function. The primary endpoint was length of hospital stay. Secondary endpoints were duration of intravenous (IV) antibiotics and time required to stabilize vital signs. Both groups demonstrated similar baseline characteristics and length of hospital stay, and yet a shorter duration of IV antibiotics was observed in the steroid group (p < 0.05). In addition, vital signs were stabilized earlier in the steroid group (p < 0.05). These differences were more prominent in the moderate-severe subgroup but not as significant in the mild-moderate subgroup. The prevalence of relative adrenal insufficiency (RAI) in both groups was high (43%), yet there was no difference in baseline characteristics between patients, with or without RAI. In multiple regression models, RAI seemed to have no influence on clinical courses.
                In moderate-severe CAP, administration of corticosteroids promotes resolution of clinical symptoms and reduces the duration of intravenous antibiotic therapy. It remains unclear whether inhaled corticosteroids can produce the maximum benefits of corticosteroids in patients with chronic obstructive pulmonary disease (COPD). To assess the additive effects of 30 mg/day prednisolone to high-dose, inhaled beclomethasone dipropionate (BDP), we conducted a randomised double-blind, placebo-controlled cross-over trial. The study population consisted of 21 men with stable COPD. The mean age of the patients was 69.1 +/- 6.8 years, and FEV(1)was 0.86 +/- 0.28 l. Seventeen out of the 21 patients (81%) were considered susceptible to steroids in a previous trial (FEV(1)increased at least 15% from baseline after receiving 14 days of 30 mg/day prednisolone). All of the patients had been on 1600 microg/day BDP for more than 3 months. Spirometry was performed before the entry, and at the end of 3-week placebo and prednisolone periods. The peak expiratory flow (PEF), symptoms, and Guyatt's Chronic Respiratory Disease Questionnaire (CRQ) as a disease specific health-related quality of life over the last seven days of each period were also evaluated. Although a marginal increase in PEF was found during the prednisolone period, no significant differences in FEV(1), FVC, symptoms or CRQ scores were observed between the two treatment periods. We conclude that the therapeutic effects of steroid therapy may be achieved by the long-term use of high-dose, inhaled corticosteroid in some patients with stable COPD.
                Copyright 2000 Academic Press. One hundred and twenty four patients with severe asthma requiring maintenance treatment with oral corticosteroids were included in a multicentre, double-blind, randomized study comparing the effects of inhaled beclomethasone dipropionate (BDP) (250 micrograms.puff-1), beginning with 1,000 micrograms daily, vs placebo (P). Pulmonary function was assessed and dosage of prednisone and BDP (or P) were adjusted every 15 days according to a clinical score. Our results showed, after 3 months: 1) A greater drop-out rate in the P group than in the BDP group (36 vs 6%, respectively, p less than 0.01); 2) A total weaning from prednisone in 76% of patients in the BDP group (mean BDP dosage = 1,270 +/- 340 micrograms.day-1, mean +/- SD), vs 34% in the P group (p less than 0.001). The mean daily dosage of prednisone was reduced from 17 +/- 7.5 mg to 3.1 +/- 7.4 mg in the BDP group vs 15.6 +/- 7.7 mg to 9.1 +/- 9.4 mg in the P group (p less than 0.001) without any relationship between the steroid-sparing effect and the initial dosage of prednisone; 3) Mean change in forced expiratory volume in one second (FEV1) was +7 +/- 21% from the initial value in the BDP group vs -6 +/- 20% in the P group; p less than 0.01. Thus, in patients with severe asthma requiring oral corticosteroids, high-dose BDP has an important oral steroid-sparing effect not related to the initial dosage of oral steroids and allows a better control of airway obstruction than oral corticosteroids alone. It is not clear whether high doses of inhaled steroids have a greater sparing effect than low doses on the requirement for systemic steroids. In a randomised, double-blind, multicentre study, we compared the effects of high-dose (1500 micrograms/day) and low-dose (300 micrograms/day) inhaled beclomethasone dipropionate (BDP) in patients with severe asthma requiring a daily oral prednisolone dose of 10-40 mg. During a 3-month run-in period, we tried to achieve optimum asthma control by means of oral steroid and inhaled BDP 300 micrograms/day. The patients were then allocated to high-dose (n = 71) or low-dose (n = 72) treatment by an independent observer who took into account various prognostic factors. BDP was administered by means of an aerosol inhaler with a spacer device. The dose of systemic steroid was reduced as much as possible during the 6-month study period while keeping the peak expiratory flow (PEF) constant and asthma clinically stable. There was no difference between the low-dose and high-dose treatment groups in the mean reduction in oral prednisolone dose achieved by the end of the study (5.2[ SD 7.9] vs 5.0 [9.4] mg/day). The maximum response to inhaled steroid was seen, however, only after several months' therapy in both groups. There were no differences between the groups in use of on-demand beta-agonist inhalations or in asthma symptoms, and PEF values were constant throughout the study. Both doses of BDP were well tolerated. High doses of inhaled steroid offer no further benefit over low doses in the maintenance treatment of severe steroid-dependent asthma when the inhaled steroid is administered with a spacer device. We wanted to evaluate the improvement in efficacy when increasing the daily dose of inhaled steroids and to compare the efficacy, safety, and tolerance of 1.6 mg beclomethasone dipropionate (BDP) with that of 2.0 mg fluticasone propionate (FP). The study was a randomized, double-blind, 3 month, multicentre study. One hundred and thirty four asthmatics currently using inhaled steroids (0.4-1.6 mg BDP or budesonide (BUD)) were stratified according to pretrial daily steroid use. Within each stratum they were randomized to either 1.6 mg BDP or 2.0 mg FP. A significant increase in the primary efficacy variables, i.e. mean morning and evening peak expiratory flow (PEF) (approximately 20 l.min-1) during the treatment period, was found for both treatments. No significant differences between the drugs were revealed for these primary or any other secondary efficacy variables (use of beta 2-agonists, symptom scores, and PEF, forced vital capacity (FVC), forced expiratory volume in one second (FEV1) recorded at the clinical visits). However, significant differences between treatments occurred regarding decrease of serum cortisol and adrenocorticotropic hormone. We conclude that, although both treatments gave statistically significant increases in efficacy parameters when compared with baseline, the increases were so small that they can be regarded as being clinically unimportant. Daily doses of BDP, 1.6 mg, and FP, 2.0 mg, had comparable effects on lung function. A suppression of the hypothalamic pituitary adrenal (HPA) axis was only found with a daily dose of 2 mg FP. In a 26-wk double-blind controlled study of 34 patients whose asthma had been poorly controlled despite oral steroids, valuable clinical and pulmonary function improvement was derived by adding beclomethasone aerosol to the prednisone regimen. The amount of improvement correlated linearly with beclomethasone dosage over the range 200 to 1,600 microng/day. These patients required relatively high dosage. Success in achieving asymptomatic status was only 26% with the conventional 400 microng/day and 60% at 1,600 microng/day. Oropharyngeal candidiasis was also dose-related but did not prohibit the use of high-dosage beclomethasone. Respiratory infections, physical signs, blood glucose, and electrolytes were unaffected by the drug. A dose-related suppression of cortisol secretion was demonstrated, but about 1/4 of the group had normal plasma cortisol even at 1,600 microng/day plus the oral prednisone. An individualized risk-benefit assessment seems a better basis for choosing an optimal beclomethasone regimen for each patient than adherence to a conventionalized fixed dosage of 400 microng/day. This requires definition of: (1) a specific goal of treatment in the individual patient and the beclomethasone dosage required to achieve it; (2) the adrenocortical functional response of that particular patient to the desired dose of beclomethasone; and (3) the presence and degree of any dose-limiting constraints such as preexisting complications of steroid use.
Very potent topical steroids are effective and safe treatments for BP, but their use in extensive disease may be limited by side-effects and practical factors. Milder regimens (using lower doses of steroids) are safe and effective in moderate BP. Starting doses of prednisolone greater than 0.75 mg/kg/day do not give additional benefit, lower doses may be adequate to control disease and reduce the incidence and severity of adverse reactions. The effectiveness of adding plasma exchange, azathioprine or mycophenolate mofetil to corticosteroids, and combination treatment with tetracycline and nicotinamide needs further investigation.
