The addition of abiraterone, a drug that blocks endogenous androgen synthesis, to standard androgen-deprivation therapy in patients with newly diagnosed, metastatic prostate cancer significantly increased overall survival, with a low rate of adverse effects.

Background To assess the food effects and pharmacokinetic profile of oral prednisone (test preparation,5 mg) and prednisolone tablets (reference preparation,5 mg) using a randomized, two-period, two crossover, single-dose, fast and fed trial in 48 (24 in fast, 24 in fed) healthy Chinese adult subjects. Materials and methods In the trial, the plasma concentrations were determined at different time points up to 24 h and the pharmacokinetic parameters were analyzed according to the concentration data by non-compartmental analysis using WinNonlin software. All laboratory parameters, vital signs and adverse events (AEs) were monitored and recorded under the supervision of the clinicians throughout the whole process of the study. Results Prednisone and prednisolone undergo interconversion in liver. On average, the bioavailability of prednisolone after oral prednisone is approximately 80% of that after prednisolone. And about 20% of prednisolone is converted to prednisone after administration of equivalent oral of prednisolone tablet. Food taken with prednisone or prednisolone tablets delays the time reach the peak prednisone or prednisolone concentration (T max ) by approximately 0.5 h but does not affect systemic exposure. Prednisone and prednisolone tablets were well tolerated, and there were no serious adverse events reported in the study. Conclusions For there was no information about the pharmacokinetic profile and food effects of oral prednisone and prednisolone tablets, the result of this research would be a clinical medication for doctors especially dealing patients with varying degrees of liver diseases. Clinical Trial Registration CTR20200093; registered in http://www.chinadrugtrials.org.cn/ at 11 March 2020. Key points • The food effects and pharmacokinetic evaluation of prednisone acetate and prednisolone were investigated in healthy Chinese subjects. • Prednisone and prednisolone undergo interconversion in liver. On average, the bioavailability of prednisolone after oral prednisone is approximately 80% of that after prednisolone. • Food taken with prednisone or prednisolone tablets delays the T max but does not affect AUC.

Objective To assess the current use of glucocorticoids (GCs) in Duchenne muscular dystrophy in the UK, and compare the benefits and the adverse events of daily versus intermittent prednisolone regimens. Design A prospective longitudinal observational study across 17 neuromuscular centres in the UK of 360 boys aged 3–15 years with confirmed Duchenne muscular dystrophy who were treated with daily or intermittent (10 days on/10 days off) prednisolone for a mean duration of treatment of 4 years. Results The median loss of ambulation was 12 years in intermittent and 14.5 years in daily treatment; the HR for intermittent treatment was 1.57 (95% CI 0.87 to 2.82). A fitted multilevel model comparing the intermittent and daily regiments for the NorthStar Ambulatory Assessment demonstrated a divergence after 7 years of age, with boys on an intermittent regimen declining faster (p<0.001). Moderate to severe side effects were more commonly reported and observed in the daily regimen, including Cushingoid features, adverse behavioural events and hypertension. Body mass index mean z score was higher in the daily regimen (1.99, 95% CI 1.79 to 2.19) than in the intermittent regimen (1.51, 95% CI 1.27 to 1.75). Height restriction was more severe in the daily regimen (mean z score −1.77, 95% CI −1.79 to −2.19) than in the intermittent regimen (mean z score −0.70, 95% CI −0.90 to −0.49). Conclusions Our study provides a framework for providing information to patients with Duchenne muscular dystrophy and their families when introducing GC therapy. The study also highlights the importance of collecting longitudinal natural history data on patients treated according to standardised protocols, and clearly identifies the benefits and the side-effect profile of two treatment regimens, which will help with informed choices and implementation of targeted surveillance.

The addition of abiraterone and prednisolone to standard androgen-deprivation therapy as the first treatment for patients with locally advanced or metastatic prostate cancer improved overall and failure-free survival, with a small increase in high-grade toxic effects.

Men with high-risk non-metastatic prostate cancer are treated with androgen-deprivation therapy (ADT) for 3 years, often combined with radiotherapy. We analysed new data from two randomised controlled phase 3 trials done in a multiarm, multistage platform protocol to assess the efficacy of adding abiraterone and prednisolone alone or with enzalutamide to ADT in this patient population. These open-label, phase 3 trials were done at 113 sites in the UK and Switzerland. Eligible patients (no age restrictions) had high-risk (defined as node positive or, if node negative, having at least two of the following: tumour stage T3 or T4, Gleason sum score of 8–10, and prostate-specific antigen [PSA] concentration ≥40 ng/mL) or relapsing with high-risk features (≤12 months of total ADT with an interval of ≥12 months without treatment and PSA concentration ≥4 ng/mL with a doubling time of <6 months, or a PSA concentration ≥20 ng/mL, or nodal relapse) non-metastatic prostate cancer, and a WHO performance status of 0–2. Local radiotherapy (as per local guidelines, 74 Gy in 37 fractions to the prostate and seminal vesicles or the equivalent using hypofractionated schedules) was mandated for node negative and encouraged for node positive disease. In both trials, patients were randomly assigned (1:1), by use of a computerised algorithm, to ADT alone (control group), which could include surgery and luteinising-hormone-releasing hormone agonists and antagonists, or with oral abiraterone acetate (1000 mg daily) and oral prednisolone (5 mg daily; combination-therapy group). In the second trial with no overlapping controls, the combination-therapy group also received enzalutamide (160 mg daily orally). ADT was given for 3 years and combination therapy for 2 years, except if local radiotherapy was omitted when treatment could be delivered until progression. In this primary analysis, we used meta-analysis methods to pool events from both trials. The primary endpoint of this meta-analysis was metastasis-free survival. Secondary endpoints were overall survival, prostate cancer-specific survival, biochemical failure-free survival, progression-free survival, and toxicity and adverse events. For 90% power and a one-sided type 1 error rate set to 1·25% to detect a target hazard ratio for improvement in metastasis-free survival of 0·75, approximately 315 metastasis-free survival events in the control groups was required. Efficacy was assessed in the intention-to-treat population and safety according to the treatment started within randomised allocation. STAMPEDE is registered with ClinicalTrials.gov, NCT00268476, and with the ISRCTN registry, ISRCTN78818544. Between Nov 15, 2011, and March 31, 2016, 1974 patients were randomly assigned to treatment. The first trial allocated 455 to the control group and 459 to combination therapy, and the second trial, which included enzalutamide, allocated 533 to the control group and 527 to combination therapy. Median age across all groups was 68 years (IQR 63–73) and median PSA 34 ng/ml (14·7–47); 774 (39%) of 1974 patients were node positive, and 1684 (85%) were planned to receive radiotherapy. With median follow-up of 72 months (60–84), there were 180 metastasis-free survival events in the combination-therapy groups and 306 in the control groups. Metastasis-free survival was significantly longer in the combination-therapy groups (median not reached, IQR not evaluable [NE]–NE) than in the control groups (not reached, 97–NE; hazard ratio [HR] 0·53, 95% CI 0·44–0·64, p<0·0001). 6-year metastasis-free survival was 82% (95% CI 79–85) in the combination-therapy group and 69% (66–72) in the control group. There was no evidence of a difference in metatasis-free survival when enzalutamide and abiraterone acetate were administered concurrently compared with abiraterone acetate alone (interaction HR 1·02, 0·70–1·50, p=0·91) and no evidence of between-trial heterogeneity (I2 p=0·90). Overall survival (median not reached [IQR NE–NE] in the combination-therapy groups vs not reached [103–NE] in the control groups; HR 0·60, 95% CI 0·48–0·73, p<0·0001), prostate cancer-specific survival (not reached [NE–NE] vs not reached [NE–NE]; 0·49, 0·37–0·65, p<0·0001), biochemical failure-free-survival (not reached [NE–NE] vs 86 months [83–NE]; 0·39, 0·33–0·47, p<0·0001), and progression-free-survival (not reached [NE–NE] vs not reached [103–NE]; 0·44, 0·36–0·54, p<0·0001) were also significantly longer in the combination-therapy groups than in the control groups. Adverse events grade 3 or higher during the first 24 months were, respectively, reported in 169 (37%) of 451 patients and 130 (29%) of 455 patients in the combination-therapy and control groups of the abiraterone trial, respectively, and 298 (58%) of 513 patients and 172 (32%) of 533 patients of the combination-therapy and control groups of the abiraterone and enzalutamide trial, respectively. The two most common events more frequent in the combination-therapy groups were hypertension (abiraterone trial: 23 (5%) in the combination-therapy group and six (1%) in control group; abiraterone and enzalutamide trial: 73 (14%) and eight (2%), respectively) and alanine transaminitis (abiraterone trial: 25 (6%) in the combination-therapy group and one (<1%) in control group; abiraterone and enzalutamide trial: 69 (13%) and four (1%), respectively). Seven grade 5 adverse events were reported: none in the control groups, three in the abiraterone acetate and prednisolone group (one event each of rectal adenocarcinoma, pulmonary haemorrhage, and a respiratory disorder), and four in the abiraterone acetate and prednisolone with enzalutamide group (two events each of septic shock and sudden death). Among men with high-risk non-metastatic prostate cancer, combination therapy is associated with significantly higher rates of metastasis-free survival compared with ADT alone. Abiraterone acetate with prednisolone should be considered a new standard treatment for this population.

High doses of corticosteroids are considered the standard treatment for pemphigus. Because long-term corticosteroid treatment can cause severe and even life-threatening side-effects in patients with this disease, we assessed whether first-line use of rituximab as adjuvant therapy could improve the proportion of patients achieving complete remission off-therapy, compared with corticosteroid treatment alone, while decreasing treatment side-effects of corticosteroids. We did a prospective, multicentre, parallel-group, open-label, randomised trial in 25 dermatology hospital departments in France (Ritux 3). Eligible participants were patients with newly diagnosed pemphigus aged 18–80 years being treated for the first time (not at the time of a relapse). We randomly assigned participants (1:1) to receive either oral prednisone alone, 1·0 or 1·5 mg/kg per day tapered over 12 or 18 months (prednisone alone group), or 1000 mg of intravenous rituximab on days 0 and 14, and 500 mg at months 12 and 18, combined with a short-term prednisone regimen, 0·5 or 1·0 mg/kg per day tapered over 3 or 6 months (rituximab plus short-term prednisone group). Follow-up was for 3 years (study visits were scheduled weekly during the first month of the study, then monthly until month 24, then an additional visit at month 36). Treatment was assigned through central computer-generated randomisation, with stratification according to disease-severity (severe or moderate, based on Harman's criteria). The primary endpoint was the proportion of patients who achieved complete remission off-therapy at month 24 (intention-to-treat analysis). This study is registered with ClinicalTrials.gov, number NCT00784589. Between May 10, 2010, and Dec 7, 2012, we enrolled 91 patients and randomly assigned 90 to treatment (90 were analysed; 1 patient withdrew consent before the random assignment). At month 24, 41 (89%) of 46 patients assigned to rituximab plus short-term prednisone were in complete remission off-therapy versus 15 (34%) of 44 assigned to prednisone alone (absolute difference 55 percentage points, 95% CI 38·4–71·7; p<0·0001. This difference corresponded to a relative risk of success of 2·61 (95% CI 1·71–3·99, p<0·0001), corresponding to 1·82 patients (95% CI 1·39–2·60) who would need to be treated with rituximab plus prednisone (rather than prednisone alone) for one additional success. No patient died during the study. More severe adverse events of grade 3–4 were reported in the prednisone-alone group (53 events in 29 patients; mean 1·20 [SD 1·25]) than in the rituximab plus prednisone group (27 events in 16 patients; mean 0·59 [1·15]; p=0·0021). The most common of these events in both groups were diabetes and endocrine disorder (11 [21%] with prednisone alone vs six [22%] with rituximab plus prednisone), myopathy (ten [19%] vs three [11%]), and bone disorders (five [9%] vs five [19%]). Data from our trial suggest that first-line use of rituximab plus short-term prednisone for patients with pemphigus is more effective than using prednisone alone, with fewer adverse events.

AbstractObjectiveTo determine whether extending initial prednisolone treatment from eight to 16 weeks in children with idiopathic steroid sensitive nephrotic syndrome improves the pattern of disease relapse.DesignDouble blind, parallel group, phase III randomised placebo controlled trial, including a cost effectiveness analysis.Setting125 UK National Health Service district general hospitals and tertiary paediatric nephrology centres.Participants237 children aged 1-14 years with a first episode of steroid sensitive nephrotic syndrome.InterventionsChildren were randomised to receive an extended 16 week course of prednisolone (total dose 3150 mg/m2) or a standard eight week course of prednisolone (total dose 2240 mg/m2). The drug was supplied as 5 mg tablets alongside matching placebo so that participants in both groups received the same number of tablets at any time point in the study. A minimisation algorithm ensured balanced treatment allocation by ethnicity (South Asian, white, or other) and age (5 years or less, 6 years or more).Main outcome measuresThe primary outcome measure was time to first relapse over a minimum follow-up of 24 months. Secondary outcome measures were relapse rate, incidence of frequently relapsing nephrotic syndrome and steroid dependent nephrotic syndrome, use of alternative immunosuppressive treatment, rates of adverse events, behavioural change using the Achenbach child behaviour checklist, quality adjusted life years, and cost effectiveness from a healthcare perspective. Analysis was by intention to treat.ResultsNo significant difference was found in time to first relapse (hazard ratio 0.87, 95% confidence interval 0.65 to 1.17, log rank P=0.28) or in the incidence of frequently relapsing nephrotic syndrome (extended course 60/114 (53%) v standard course 55/109 (50%), P=0.75), steroid dependent nephrotic syndrome (48/114 (42%) v 48/109 (44%), P=0.77), or requirement for alternative immunosuppressive treatment (62/114 (54%) v 61/109 (56%), P=0.81). Total prednisolone dose after completion of the trial drug was 6674 mg for the extended course versus 5475 mg for the standard course (P=0.07). There were no statistically significant differences in serious adverse event rates (extended course 19/114 (17%) v standard course 27/109 (25%), P=0.13) or adverse event rates, with the exception of behaviour, which was poorer in the standard course group. Scores on the Achenbach child behaviour checklist did not, however, differ. Extended course treatment was associated with a mean increase in generic quality of life (0.0162 additional quality adjusted life years, 95% confidence interval −0.005 to 0.037) and cost savings (difference −£1673 ($2160; €1930), 95% confidence interval −£3455 to £109).ConclusionsClinical outcomes did not improve when the initial course of prednisolone treatment was extended from eight to 16 weeks in UK children with steroid sensitive nephrotic syndrome. However, evidence was found of a short term health economic benefit through reduced resource use and increased quality of life.Trial registrationISRCTN16645249; EudraCT 2010-022489-29.

In this randomized trial in patients hospitalized with alcoholic hepatitis, pentoxifylline did not improve survival. The 28-day survival advantage in patients treated with prednisolone did not reach significance and was not sustained at 90 days or 1 year. Alcoholic hepatitis is a distinct manifestation of alcoholic liver disease that is characterized by jaundice and liver failure. This condition develops in persons with a history of prolonged and heavy alcohol use. 1 The severity of alcoholic hepatitis is conventionally defined by Maddrey’s discriminant function, which is calculated as 4.6×(patient’s prothrombin time in seconds−control’s prothrombin time in seconds)+patient’s serum bilirubin level in milligrams per deciliter; a value of 32 or higher indicates severe alcoholic hepatitis that carries an adverse prognosis, with mortality of 20 to 30% within 1 month after presentation and 30 to 40% within 6 months after presentation. 2 A . . .

ObjectiveCorticosteroid has been established as the standard therapy for autoimmune pancreatitis (AIP), but the requirement for maintenance corticosteroid therapy is controversial. We conducted a randomised controlled trial to clarify the efficacy of maintenance corticosteroid therapy in patients with AIP.DesignWe conducted a multicentre, tertiary setting, randomised controlled trial. After the induction of remission with the initial oral prednisolone (PSL) treatment, maintenance therapy with PSL at 5–7.5 mg/day was continued for 3 years or withdrawn at 26 weeks. The primary endpoint was relapse-free survival over 3 years and the secondary endpoint was serious corticosteroid-related complications. All analyses were performed on an intention-to-treat basis.ResultsBetween April 2009 and March 2012, 49 patients with AIP were randomly assigned to the maintenance therapy group (n=30) or the cessation group (n=19). Baseline characteristics were not different between the two groups. Relapses occurred within 3 years in 11 out of 19 (57.9%) patients assigned to the cessation group, and in 7 of 30 (23.3%) patients in the maintenance therapy group. The relapse rate over 3 years was significantly lower in the maintenance therapy group than that in the cessation group (p=0.011). The relapse-free survival was significantly longer in the maintenance therapy group than that in the cessation group (p=0.007). No serious corticosteroid-related complications requiring discontinuation of PSL were observed.ConclusionsMaintenance corticosteroid therapy for 3 years may decrease relapses in patients with AIP compared with those who discontinued the therapy at 26 weeks.Trial registration numberUMIN000001818; Results.

IntroductionThe optimal prednisolone dose for managing acute calcium pyrophosphate (CPP) crystal arthritis remains unclear. We compared the efficacy and safety of 10- and 30-mg daily doses of prednisolone for acute CPP crystal arthritis.MethodThis randomized, controlled, open-label trial included patients with acute CPP crystal arthritis and symptoms that had begun less than 72 h earlier. Patients without CPP crystals, those with septic arthritis, and those with uncontrolled infections were excluded. Participants received either 10 or 30 mg of prednisolone daily for 7 days. The primary outcome was time until complete resolution of symptoms; secondary outcomes included time until clinical resolution, recurrence rates, laboratory profiles, and adverse events, adjusted for confounders.ResultsSeventy-nine patients participated. Baseline characteristics were comparable, except that the 30-mg recipients had more initial inpatient visits (p = 0.03). The median time until complete resolution was 7 days in both groups (p = 0.73). The 30-mg recipients exhibited faster clinical resolution (1 vs. 3 days; p = 0.03), but adjusted analyses revealed no significant differences in time until complete resolution (6.2 vs. 6.5 days; p = 0.68) or clinical resolution (2.4 vs. 2 days; p = 0.27). The overall recurrence rate was 14.3%; the 30-mg recipients experienced slightly more recurrences (p = 0.08). The other secondary outcomes did not differ significantly.ConclusionsThe 10- and 30-mg daily doses of prednisolone were equally effective in treating acute symptoms of CPP crystal arthritis, with no significant differences in resolution time, recurrence rates, or safety outcomes.Key Points• A randomized controlled trial compared 10 mg and 30 mg daily prednisolone doses for acute CPP crystal arthritis.• Both doses resulted in similar times to complete symptom resolution and recurrence rates.• The 30-mg dose led to faster initial symptom relief, but adjusted analyses showed no significant differences.• Both doses were equally safe, with no significant differences in adverse events.
