Efficacy of Inhaled Ciclesonide for Outpatient Treatment of Adolescents and Adults With Symptomatic COVID-19: A Randomized Clinical Trial.

Importance: Systemic corticosteroids are commonly used in treating severe COVID-19. However, the role of inhaled corticosteroids in the treatment of patients with mild to moderate disease is less clear. Objective: To determine the efficacy of the inhaled steroid ciclesonide in reducing the time to alleviation of all COVID-19-related symptoms among nonhospitalized participants with symptomatic COVID-19 infection. Design, Setting, and Participants: This phase 3, multicenter, double-blind, randomized clinical trial was conducted at 10 centers throughout the US and assessed the safety and efficacy of a ciclesonide metered-dose inhaler (MDI) for treating nonhospitalized participants with symptomatic COVID-19 infection who were screened from June 11, 2020, to November 3, 2020. Interventions: Participants were randomly assigned to receive ciclesonide MDI, 160 µg per actuation, for a total of 2 actuations twice a day (total daily dose, 640 µg) or placebo for 30 days. Main Outcomes and Measures: The primary end point was time to alleviation of all COVID-19-related symptoms (cough, dyspnea, chills, feeling feverish, repeated shaking with chills, muscle pain, headache, sore throat, and new loss of taste or smell) by day 30. Secondary end points included subsequent emergency department visits or hospital admissions for reasons attributable to COVID-19. Results: A total of 413 participants were screened and 400 (96.9%) were enrolled and randomized (197 [49.3%] in the ciclesonide arm and 203 [50.7%] in the placebo arm; mean [SD] age, 43.3 [16.9] years; 221 [55.3%] female; 2 [0.5%] Asian, 47 [11.8%] Black or African American, 3 [0.8%] Native Hawaiian or other Pacific Islander, 345 [86.3%] White, and 1 multiracial individuals [0.3%]; 172 Hispanic or Latino individuals [43.0%]). The median time to alleviation of all COVID-19-related symptoms was 19.0 days (95% CI, 14.0-21.0) in the ciclesonide arm and 19.0 days (95% CI, 16.0-23.0) in the placebo arm. There was no difference in resolution of all symptoms by day 30 (odds ratio, 1.28; 95% CI, 0.84-1.97). Participants who were treated with ciclesonide had fewer subsequent emergency department visits or hospital admissions for reasons related to COVID-19 (odds ratio, 0.18; 95% CI, 0.04-0.85). No participants died during the study. Conclusions and Relevance: The results of this randomized clinical trial demonstrated that ciclesonide did not achieve the primary efficacy end point of reduced time to alleviation of all COVID-19-related symptoms.

Guidelines on the management of acute respiratory distress syndrome.

The Faculty of Intensive Care Medicine and Intensive Care Society Guideline Development Group have used GRADE methodology to make the following recommendations for the management of adult patients with acute respiratory distress syndrome (ARDS). The British Thoracic Society supports the recommendations in this guideline. Where mechanical ventilation is required, the use of low tidal volumes (<6 ml/kg ideal body weight) and airway pressures (plateau pressure <30 cmH2O) was recommended. For patients with moderate/severe ARDS (PF ratio<20 kPa), prone positioning was recommended for at least 12 hours per day. By contrast, high frequency oscillation was not recommended and it was suggested that inhaled nitric oxide is not used. The use of a conservative fluid management strategy was suggested for all patients, whereas mechanical ventilation with high positive end-expiratory pressure and the use of the neuromuscular blocking agent cisatracurium for 48 hours was suggested for patients with ARDS with ratio of arterial oxygen partial pressure to fractional inspired oxygen (PF) ratios less than or equal to 27 and 20 kPa, respectively. Extracorporeal membrane oxygenation was suggested as an adjunct to protective mechanical ventilation for patients with very severe ARDS. In the absence of adequate evidence, research recommendations were made for the use of corticosteroids and extracorporeal carbon dioxide removal.

Acute Severe Autoimmune Hepatitis: Corticosteroids or Liver Transplantation?

Acute severe presentations of autoimmune hepatitis (AIH) represent a challenge for the transplant community. As a disease, it is poorly characterized, and there is a weak evidence base to guide diagnosis and treatment. Early identification of acute severe AIH is key because it determines the initiation of corticosteroids, which can be lifesaving. However, their use in this setting remains controversial. The Model for End-Stage Liver Disease score, severity of coagulopathy, and grade of encephalopathy may be predictors of outcome with corticosteroid therapy. The optimal timing of liver transplantation (LT) can be difficult to determine and, as such, the decision to proceed to transplantation should not be delayed by protracted courses of corticosteroids. The aim of this review is to better characterize this subset of patients; to differentiate them clinically, serologically, and histologically from chronic AIH and other causes of acute liver failure; and to present the role, predictors, and optimal timings of corticosteroid therapy and LT. Although this review is specific to adults, many principles hold true for the pediatric population.

Identification and characterization of unknown degradation impurities in beclomethasone dipropionate cream formulation using HPLC, ESI-MS and NMR.

The present study focuses on identifying the degradation profile and pathways of unknown impurities from beclomethasone dipropionate (BDP) topical cream formulation reported under accelerated stability conditions. Six degradation impurities were observed during the accelerated stability testing of BDP topical cream formulation, and these thermally labile degradation impurities were primarily identified using a simple, effective and mass compatible isocratic reversed-phase high-performance liquid chromatography with ultraviolet detection method. The degradation impurities found in this sample were of very low concentration levels, thus the concentration of these impurities in the sample was enriched by mimicking the thermal degradation conditions to structurally elucidate the unknown impurities. These BDP thermal degradation impurities were isolated using preparative liquid chromatography and followed by pre-concentration using rota-vapour. Further, the collected thermal degradation impurities were characterized using ESI-MS, and the major impurity was identified using 1H and C13 NMR spectroscopy, and DEPT technique. Plausible degradation pathway and mechanism of each impurity from BDP has been proposed based on the obtained mass and NMR spectral data. Thus, the present method is simple and suitable to be applied towards BDP assay in various formulations, and also to investigate the thermal stability and degradation kinetics of the final drug product.

2018 update of the EULAR recommendations for the management of hand osteoarthritis.

Since publication of the European League Against Rheumatism (EULAR) recommendations for management of hand osteoarthritis (OA) in 2007 new evidence has emerged. The aim was to update these recommendations. EULAR standardised operating procedures were followed. A systematic literature review was performed, collecting the evidence regarding all non-pharmacological, pharmacological and surgical treatment options for hand OA published to date. Based on the evidence and expert opinion from an international task force of 19 physicians, healthcare professionals and patients from 10 European countries formulated overarching principles and recommendations. Level of evidence, grade of recommendation and level of agreement were allocated to each statement. Five overarching principles and 10 recommendations were agreed on. The overarching principles cover treatment goals, information provision, individualisation of treatment, shared decision-making and the need to consider multidisciplinary and multimodal (non-pharmacological, pharmacological, surgical) treatment approaches. Recommendations 1-3 cover different non-pharmacological treatment options (education, assistive devices, exercises and orthoses). Recommendations 4-8 describe the role of different pharmacological treatments, including topical treatments (preferred over systemic treatments, topical non-steroidal anti-inflammatory drugs (NSAIDs) being first-line choice), oral analgesics (particularly NSAIDs to be considered for symptom relief for a limited duration), chondroitin sulfate (for symptom relief), intra-articular glucocorticoids (generally not recommended, consider for painful interphalangeal OA) and conventional/biological disease-modifying antirheumatic drugs (discouraged). Considerations for surgery are described in recommendation 9. The last recommendation relates to follow-up. The presented EULAR recommendations provide up-to-date guidance on the management of hand OA, based on expert opinion and research evidence.

Seventeen-Year Nationwide Trends in Use of Long-acting Bronchodilators and Inhaled Corticosteroids among Adults - A Danish Drug Utilization Study.

Long-acting bronchodilators and inhaled corticosteroids (ICS) are the cornerstones in treatment of chronic obstructive and inflammatory pulmonary diseases. However, non-adherence to guidelines is widespread. Detailed information on real-life treatment patterns is needed to promote rational use. We aimed to investigate nationwide time trends in individual-level treatment patterns of long-acting bronchodilators and ICS. Using nationwide Danish health registries, we identified all Danish adults with a prescription for long-acting bronchodilators and/or ICS from 2000 to 2016. We investigated the total use of long-acting bronchodilators and ICS, the proportion of current users and the rate of new users over time. Finally, we assessed treatment persistence. We included 23,061,681 prescriptions for long-acting bronchodilators and ICS issued to 805,860 individuals from 2000 to 2016. Over this period, the total annual amount of prescribed long-acting bronchodilators and ICS increased by 39%. Similarly, the proportion of adult users increased from 2.6% to 4.5%, mainly driven by the introduction of combination therapy and long-acting muscarinic antagonist (LAMA). Although the rate of new users of fixed-dose combination drugs increased substantially over time, the overall rate of new users was stable. In general, the proportion of patients on therapy after 1 year was low (25-53%), especially among young individuals and users of ICS. We document a pronounced increase in the total use of long-acting bronchodilators and ICS over time, mainly driven by the introduction of combination drugs and LAMA. Special attention should be paid to the low level of persistence, especially among young individuals and users of ICS.

Gas chromatography tandem mass spectrometry offers advantages for urinary steroids analysis.

Gas chromatography mass spectrometry has been the lynchpin of clinical assessment of steroid profiles for ∼3 decades. The improvements in assay performance offered by tandem mass spectrometry were assessed. Across the spectrum of glucocorticoid and androgen analytes tested, limits of detection and quantitation were ∼20 fold lower with triple than single quadrupole systems, but the more noticeable improvement was that signal to noise was substantially improved and the linear range wider. These benefits allowed more reliable and concomitant measurement of steroids with substantially different abundances and in smaller volumes of urine.

"Official View" on Glucocorticoids in Rheumatoid Arthritis: A Systematic Review of International Guidelines and Consensus Statements.

OBJECTIVE: To describe the perception of the current role of systemic glucocorticoids in the management of rheumatoid arthritis (RA) by examining their importance and the current level of evidence in recent guidelines, and to identify open questions to be addressed in future guidelines and research projects. METHODS: We conducted a systematic literature review using the databases Ovid Embase, PubMed Medline, and Cochrane Library for guidelines on the pharmacologic treatment of RA. Retrieved articles were evaluated regarding their quality using the Appraisal of Guidelines for Research and Evaluation II tool and scrutinized for all relevant information concerning the use of glucocorticoids. RESULTS: All guidelines agree that glucocorticoids, especially if given at low doses and for a short duration, are an appropriate option in the treatment of RA. However, many recommendations remain vague, as reliable and detailed evidence is scarce. Important aspects of glucocorticoid therapy are partially or completely neglected, and the existing nomenclature is not used uniformly. Quality evaluation revealed flaws in many articles, concerning not only glucocorticoid-specific recommendations but also guideline quality in general. CONCLUSION: Current recommendations for use of glucocorticoids in the management of RA are suboptimal. More rigorous evaluation of doses, timing, and duration of their use is needed. Existing nomenclature on glucocorticoid therapy should be used uniformly.

TLC--densitometric method for qualitative analysis of betamethasone and its related compounds in pharmacautical preparations.

A new simple and rapid TLC-densitometric procedure for the separation and identification of betamethasone and its related substances, betamethasone-17,21-dipropionate, betamethasone-17-valerate, betamethasone-21-valerate and also betamethasone disodium phosphate was developed. One of the chromatographic systems proposed in this study, which has been satisfactory applied in separation of four pairs of examined compounds was silica gel 60F254 (E. Merck, Art. 1.05554) and a mixture containing chloroform-methanol-acetic acid (99.5%) in volume composition 28:5:0.5. Densitometric measurements were done using densitometer TLC Scanner 3 at 246 nm. The proposed method was checked in terms of its specificity for the determination of betamethasone-17,21-dipropionate and betamethasone disodium phosphate in commercially available products containing both compounds, separately, as active ingredients. The results showed that the method is suitable for qualitative analysis of betamethasone derivatives in simple and combined pharmaceuticals in various dosage forms e.g., lotion and injection solution. It also can be applied in quality control of pharmaceutical formulations of betamethasone and its related compounds in form of salts and esters.

The use of glucocorticoids in systemic lupus erythematosus. After 60 years still more an art than science.

Systemic Lupus Erythematosus (SLE) is a clinically diverse, chronic autoimmune disease with inflammation in several organ systems. Its pathogenesis is complex, but includes many factors that can be influenced by glucocorticoids (GCs). Indeed, GCs constitute the corner-stone in SLE-treatment. However, guidelines for GC-treatment of the different disease manifestations are lacking and not every patient responds (sufficiently). The focus of this systematic review is to evaluate the differential glucocorticoid treatment of various SLE manifestations. In addition, some relevant mechanisms of glucocorticoid action as well as resistance are discussed.

Comparison of results of adrenocorticotropic hormone stimulation and low-dose dexamethasone suppression tests with necropsy findings in dogs: 81 cases (1985-1995).

OBJECTIVE: Comparison of diagnostic accuracy of results of low-dose dexamethasone suppression (LDDS) and ACTH stimulation tests with necropsy findings in 81 dogs. DESIGN: Retrospective study. ANIMALS: 81 dogs that had undergone screening tests for hyperadrenocorticism and that had a complete necropsy report. PROCEDURE: Medical records were evaluated for results of CBC, serum biochemical analysis, urinalysis, endocrine testing, signalment, treatment, and necropsy findings. Each dog was definitively classified as having true-positive, true-negative, false-positive, or false-negative results. Statistical analyses included determination of prevalence, apparent prevalence, accuracy, number of dogs misclassified, sensitivity, specificity, and positive- and negative-predictive values. RESULTS: Of the 81 dogs that fit the criteria for selection, 40 (49%) were confirmed as having hyperadrenocorticism (30 had pituitary-dependent disease and 10 had adrenal gland tumors). Forty-one dogs had illnesses attributable to a cause other than disease of the adrenal glands. Sensitivity of ACTH stimulation and LDDS tests were 95 and 96%, respectively. Specificity for the ACTH stimulation test was higher (91%) than that of the LDDS test (70%). When prevalence of the disease in the study population was taken into consideration, the positive-predictive value for the ACTH stimulation test was 91%, compared with 76% for the LDDS test. CLINICAL IMPLICATIONS: The ACTH stimulation test was more specific than the LDDS test, although sensitivity was similar for both tests. The ACTH stimulation test also had a significantly higher positive-predictive value than the LDDS test when a prevalence of 25% was taken into consideration.

Glucocorticoid receptor in patients with lupus nephritis: relationship between receptor levels in mononuclear leukocytes and effect of glucocorticoid therapy.

We investigated the clinical significance of glucocorticoid receptor determination in 20 patients with systemic lupus erythematosus (SLE) who afterwards developed nephrotic syndrome. Glucocorticoid receptor concentrations in mononuclear leukocytes (MNL) in these patients were comparable with those in both other patients with SLE and healthy persons. Improvement in urinary protein excretion and in disease activity, which was scored according to the SLE Disease Activity Index system of the University of Toronto, closely related to the glucocorticoid receptor concentrations in MNL isolated from the corresponding patients. In summary, glucocorticoid receptor determination in patients with lupus nephritis may be a predictive clue for assessing responsiveness to glucocorticoid therapy.

A comparison of the potencies of several diluted and undiluted corticosteroid preparations using the vasoconstrictor assay.

10 subjects were assessed using the vasoconstrictor assay technique in a double-blind study in order to evaluate the relative potencies of several diluted and undiluted proprietary corticosteroid preparations. Dermovate ointment achieved a significantly higher score than any other preparation but there was no significant difference between the scores for Betnovate ointment (betamethasone valerate 0.1%), Propaderm Forte cream (beclomethasone dipropionate 0.5%), Propaderm ointment (beclomethasone dipropionate 0.025%), Nerisone Forte ointment (diflucortolone valerate 0.3%), and Nerisone ointment (diflucortolone valerate 0.1%). Furthermore, no significant difference in scores could be demonstrated between Adcortyl ointment (triamcinolone acetonide 0.1%), Ledercort ointment (triamcinolone acetonide 0.1%) and extemporaneous dilutions of these ointments 1 part in 4 in their recommended diluents (triamcinolone acetonide 0.025%). The relevance of these findings to clinical practice is discussed.
