Incidence of serious complications of corticosteroid therapy in respiratory disease. A retrospective survey of patients in the Brompton hospital

A 4-Year Retrospective Claims Analysis of Oral Corticosteroid Use and Health Conditions in Newly Diagnosed Medicare FFS Patients with COPD

Purpose

We analyzed population-level administrative claims data for Medicare fee-for-service (FFS) beneficiaries to provide insights on systemic oral corticosteroid (OCS) use patterns and associated health conditions and acute events among patients newly diagnosed with chronic obstructive pulmonary disease (COPD).

Background

COPD is a progressive inflammatory disease of the lungs, characterized by acute exacerbations that may lead to increased mortality. Short courses of systemic corticosteroids (SCS) are recommended to reduce recovery time from exacerbations, although SCS use has been associated with increased risk of adverse events.

Methods

This study used 2013-2019 Medicare 100% FFS research identifiable files, which contain all Medicare Parts A, B, and D paid claims incurred by 100% of Medicare FFS beneficiaries. Descriptive statistics for patients newly diagnosed with COPD were analyzed, including OCS use, select health conditions and acute events, and COPD exacerbations. Statistical models were used to analyze the relationship between the incidence of select health conditions and events and cumulative OCS dosage.

Results

Of Medicare FFS patients newly diagnosed with COPD, 36% received OCS in the 48 months following diagnosis, and 38% of OCS episodes lasted longer than the recommended 5-7 days. Patients had a variety of health conditions or acute events in the 24-month period prior to new COPD diagnosis, such as hypertension, depression/anxiety, type 2 diabetes, or osteoporosis, that could heighten the risks of OCS use. Patients treated with >1000 mg of prednisolone equivalent OCS in the 48 months following COPD diagnosis had a higher incidence of new conditions or events, including cardiovascular disease, heart failure, hypertension, obesity, dyspepsia, infections, and depression/anxiety, than patients with no OCS use.

Conclusion

These results highlight the potential risks of OCS in COPD treatment, including prolonged use among complex Medicare patients, and reinforce the importance of preventive treatment strategies and therapy optimization early in the disease course.

Nanotechnology based advanced therapeutic strategies for targeting interleukins in chronic respiratory diseases

Both communicable and non-communicable chronic respiratory conditions have accorded for suffering of millions of people of all ages and stated to be leading cause of death, morbidity, economic and social pressures, and disability-adjusted life-years (DALYs) worldwide. These illnesses impair patient's health and negatively impacts families and society, particularly in low and middle-income countries. Chronic respiratory diseases (CRDs) affect different organs of respiratory system, involving airways, parenchyma, and pulmonary vasculature. As the number of respiratory diseases are exponentially escalating but still the stakeholders are not paying attention towards its serious complications. Currently, the treatment being used primarily focusses only on alleviating symptoms of these illness rather delivering the therapeutic agent at target site for optimal care and/or prevention. Lately, extensive research is being conducted on airways and systemic inflammation, oxidative stress, airway, or parenchymal rehabilitation. From which macrophages, neutrophils, and T cells, as well as structural cells as fibroblasts, epithelial, endothelial, and smooth muscle cells have been found to be active participants that are involved in these chronic respiratory diseases. The pathogenesis of all these chronic respiratory diseases gets caused differently via mediators and proteins, including cytokines, chemokines, growth factors and oxidants. Presently, the target of prescription therapies is to reduce the inflammation of airways and relieve the airway contraction. In all studies, cytokines have been found to play an imperative role in fostering chronic airway inflammation and remodelling. Owing to the limitations of conventional treatments, the current review aims to summarize the current knowledge about the chronic respiratory disease and discuss further about the various conventional methods that can be used for treating this ailment. Additionally, it also highlights and discusses about the advanced drug delivery system that are being used for targeting the interleukins for the treatment of CRDs.

Oral corticosteroids stewardship for asthma in adults and adolescents: A position paper from the Thoracic Society of Australia and New Zealand

Oral corticosteroids (OCS) are frequently used for asthma treatment. This medication is highly effective for both acute and chronic diseases, but evidence indicates that indiscriminate OCS use is common, posing a risk of serious side effects and irreversible harm. There is now an urgent need to introduce OCS stewardship approaches, akin to successful initiatives that optimized appropriate antibiotic usage. The aim of this TSANZ (Thoracic Society of Australia and New Zealand) position paper is to review current knowledge pertaining to OCS use in asthma and then delineate principles of OCS stewardship. Recent evidence indicates overuse and over-reliance on OCS for asthma and that doses >1000 mg prednisolone-equivalent cumulatively are likely to have serious side effects and adverse outcomes. Patient perspectives emphasize the detrimental impacts of OCS-related side effects such as weight gain, insomnia, mood disturbances and skin changes. Improvements in asthma control and prevention of exacerbations can be achieved by improved inhaler technique, adherence to therapy, asthma education, smoking cessation, multidisciplinary review, optimized medications and other strategies. Recently, add-on therapies including novel biological agents and macrolide antibiotics have demonstrated reductions in OCS requirements. Harm reduction may also be achieved through identification and mitigation of predictable adverse effects. OCS stewardship should entail greater awareness of appropriate indications for OCS prescription, risk-benefits of OCS medications, side effects, effective add-on therapies and multidisciplinary review. If implemented, OCS stewardship can ensure that clinicians and patients with asthma are aware that OCS should not be used lightly, while providing reassurance that asthma can be controlled in most people without frequent use of OCS.

The use of a standardized order set reduces systemic corticosteroid dose and length of stay for individuals hospitalized with acute exacerbations of COPD: a cohort study

Background

Systemic corticosteroids (SC) are an integral part of managing acute exacerbations of COPD (AECOPD). However, the optimal dose and duration vary widely in clinical practice. We hypothesized that the use of a “PowerPlan” order set in the electronic health system (EHS) that includes a 5-day SC order would be associated with a reduced steroid dose and length of stay (LOS) for individuals hospitalized with AECOPD.

Patients and methods

We conducted a retrospective cohort study of Medicare recipients discharged with an AECOPD diagnosis from our University Hospital from 2014 to 2016. Our EHS-based “COPD PowerPlan” order set included admission, laboratory, pharmacy, and radiology orders for managing AECOPD. The default SC option included intravenous methyl-prednisolone for 24 hours followed by oral prednisone for 4 days. The primary endpoint was the difference in cumulative steroid dose between the PowerPlan and the usual care group. Secondary endpoints included hospital LOS and readmission rates.

Results

The 250 patients included for analysis were 62±11 years old, 58% male, with an FEV₁ 55.1%±23.6% predicted. The PowerPlan was used in 72 (29%) patients. Cumulative steroid use was decreased by 31% in the PowerPlan group (420±224 vs 611±462 mg, P<0.001) when compared with usual care. PowerPlan use was independently associated with decreased LOS (3 days; IQR 2–4 days vs 4 days; IQR 3–6 days, P=0.022) without affecting 30- and 90-day readmission rates.

Conclusion

Use of a standardized EHS-based order set to manage AECOPD was associated with a reduction in steroid dose and hospital LOS.

Tuberculosis is a rare and usually fatal complication of renal transplantation. From 82 transplants in seven years, 4 cases of tuberculosis are reported. All have been treated successfully, with no fatalities or deterioration in renal function.

Steroid-induced impairment of glucose tolerance: Prevalence among pediatric patients on long-term steroid use in Nigeria

INTRODUCTION

Glucocorticoid (referred to from here on as simply steroid) is used for effective treatment of various inflammatory disorders since its discovery in 1940s. However, these useful drugs cause important side effects, such as impairment of glucose tolerance. We sought to determine the prevalence of steroid-induced impairment of glucose tolerance in pediatric patients on long-term steroid use.

MATERIALS AND METHODS

A cross-sectional, descriptive and hospital-based study. Consenting subjects who met the inclusion criteria were screened with random glucometer measurements repeated twice. An average of both readings obtained from the initial measurement of their random blood glucose (RBG) and a repeat during the next clinic visit was taken as the RBG.

RESULTS

Hundred patients were studied, 66 males/34 females. Subjects with nephrotic syndrome were 61 while 39 had asthma. Mean age of 10.13 years (range: 0.5-18 years); mean body mass index (BMI): 18.2 kg/m² (range: 6.6 to 26.30 kg/m² ). The subjects with nephrotic syndrome were on oral prednisolone while the asthmatics were on inhaled fluticasone, budesonide and oral methylprednisolone. Mean (range) duration of steroid use was 9.74 (0.5-72) months. Mean (range) RBG was 3.49 (3.3-7.5) mmol/L. None of the subjects showed abnormal RBG. However, the RBG was further categorized into low, moderate and high normal RBG. A positive correlation between longer duration of steroid use as well as high doses of both oral and inhaled steroids, and high normal RBG existed (P = .015). No statistically significant relationship existed between body mass index (BMI) percentile and RBG (P = .437).

CONCLUSION

Low to moderate doses of oral and inhaled steroids should be used when indicated as they are associated with lesser risk of impairment of glucose tolerance in the pediatric population.

Comorbidity in severe asthma requiring systemic corticosteroid therapy: cross-sectional data from the Optimum Patient Care Research Database and the British Thoracic Difficult Asthma Registry

OBJECTIVE

To determine the prevalence of systemic corticosteroid-induced morbidity in severe asthma.

DESIGN

Cross-sectional observational study.

SETTING

The primary care Optimum Patient Care Research Database and the British Thoracic Society Difficult Asthma Registry.

PARTICIPANTS

Optimum Patient Care Research Database (7195 subjects in three age- and gender-matched groups)-severe asthma (Global Initiative for Asthma (GINA) treatment step 5 with four or more prescriptions/year of oral corticosteroids, n=808), mild/moderate asthma (GINA treatment step 2/3, n=3975) and non-asthma controls (n=2412). 770 subjects with severe asthma from the British Thoracic Society Difficult Asthma Registry (442 receiving daily oral corticosteroids to maintain disease control).

MAIN OUTCOME MEASURES

Prevalence rates of morbidities associated with systemic steroid exposure were evaluated and reported separately for each group.

RESULTS

748/808 (93%) subjects with severe asthma had one or more condition linked to systemic corticosteroid exposure (mild/moderate asthma 3109/3975 (78%), non-asthma controls 1548/2412 (64%); p<0.001 for severe asthma versus non-asthma controls). Compared with mild/moderate asthma, morbidity rates for severe asthma were significantly higher for conditions associated with systemic steroid exposure (type II diabetes 10% vs 7%, OR=1.46 (95% CI 1.11 to 1.91), p<0.01; osteoporosis 16% vs 4%, OR=5.23, (95% CI 3.97 to 6.89), p<0.001; dyspeptic disorders (including gastric/duodenal ulceration) 65% vs 34%, OR=3.99, (95% CI 3.37 to 4.72), p<0.001; cataracts 9% vs 5%, OR=1.89, (95% CI 1.39 to 2.56), p<0.001). In the British Thoracic Society Difficult Asthma Registry similar prevalence rates were found, although, additionally, high rates of osteopenia (35%) and obstructive sleep apnoea (11%) were identified.

CONCLUSIONS

Oral corticosteroid-related adverse events are common in severe asthma. New treatments which reduce exposure to oral corticosteroids may reduce the prevalence of these conditions and this should be considered in cost-effectiveness analyses of these new treatments.

Increased incidence of invasive bacterial disease in chronic obstructive pulmonary disease compared to the general population--a population based cohort study

BACKGROUND

Innate defence mechanisms of the airways are impaired in chronic obstructive pulmonary disease (COPD), predisposing patients to lower respiratory tract infections, but less is known about the association with other infections. In this population-based cohort study, we investigated the associations between COPD and invasive bacterial disease by comparing incidence rates of bacteraemia in COPD patients and randomly selected reference individuals from the general population.

METHODS

In this population based cohort study all patients with COPD, ≥40 years of age, who were discharged from hospitals in southern Sweden between 1990 and 2003 were identified in the Swedish Inpatient Register (n = 15,403). Age and gender matched reference individuals were randomly selected from the general population. Records were cross-referenced to the microbiological databases covering the region, 1990-2010. The hazard ratios (HR) of bloodstream infections and hospitalisations for infections were estimated by Cox proportional hazards regression.

RESULTS

We found that individuals with COPD had a 2.5-fold increased incidence of bacteraemia compared to the reference individuals from the general population adjusted for other co-morbidity and socio-economic status (hazard ratio: 2.5, 95% confidence interval: 2.2-2.7). The increased incidence of bacteraemia was paralleled by an increased incidence of hospitalisation for non-respiratory infections, i.e., skin infections, pyelonephritis, or septic arthritis. Despite higher absolute rates of bloodstream infections among COPD patients than among the general population, the distribution of different pathogens was similar.

CONCLUSIONS

In summary this population-based study shows COPD is associated with an increased incidence of invasive bacterial infections compared to the general population, indicating a general frailty of acquiring severe infections in addition to the specific susceptibility to infections of respiratory origin. The underlying contributory factors (e.g. smoking, corticosteroid use, co-morbid diseases or a frailty inherent to COPD itself) need to be disentangled in further studies.

Steroid induced rare bipolar mood disorder

A patient with multiple psychosomatic disorder developed a steroid induced rare bipolar mood disorder (both mania and depression). The "unmasking effect" of steroids and a positive family history of psychiatric disorder as a possible risk factor, hitherto undocumented, is suggested in steroid induced psychosis.

Evaluation of weekly-reduction regimen of glucocorticoids in combination with cyclophosphamide for anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis in Japanese patients

The current therapeutic regimen recommended by the European League against Rheumatism (EULAR) for anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV) is continuation of initially administered doses of glucocorticoids (GCs) in combination with cyclophosphamide (CYC) for 1 month followed by gradual tapering. Considering the adverse effects of GCs, another tapering regimen of GCs with CYC, which was characterized by tapering GCs weekly, was reported by the British Society of Rheumatology (weekly-reduction regimen). The aim of the present study is to evaluate the safety and efficacy of this weekly-reduction regimen for Japanese AAV patients in comparison with the monthly-reduction regimen recommended by the EULAR. We retrospectively reviewed medical records of adult patients newly diagnosed with AAV during the period from April 2000 to December 2010. The outcome measures were rates of remission, relapse, infection, and GC-induced diabetes mellitus during the first 12 months. Clinical data in the two groups and categorial variables with a possible relation to the outcomes were compared by using the t test and chi-square test, respectively. Twenty-four patients were enrolled in our study. All of the patients achieved remission, and the rates of relapse during the first 12 months were not statistically different between the two groups (P = 0.16). Patients treated with the weekly-reduction regimen were less liable to have infection (P = 0.03) and impaired glucose tolerance (P = 0.017), compared with those treated with the monthly-reduction regimen. A therapeutic strategy using the weekly-reduction regimen of GCs would be effective and would have fewer side effects than the monthly-reduction regimen.

The effect of steroid use in hospitalized adults with respiratory syncytial virus-related illness

Rationale

Systemic glucocorticosteroids (steroids) are commonly prescribed for patients with exacerbations of COPD during acute viral infections such as respiratory syncytial virus (RSV). The effects of short-term high-dose steroid treatment on viral load and adaptive immunity to RSV have not been examined in adults.

Objectives

The objectives of this study were to measure peak viral load and duration of viral shedding, serum and nasal cytokines, RSV-specific antibody response, and lymphocyte subsets in patients admitted to the hospital with RSV infection and to compare patients treated with steroids to patients untreated with steroids.

Methods

Hospitalized adults who tested positive for RSV by reverse transcription-polymerase chain reaction (RT-PCR) on admission had respiratory samples collected for quantitative RT-PCR and cytokine analysis. Serum and nasal secretions were tested for RSV antibody and lymphocyte subsets were analyzed by flow cytometry at 2 days, 2 weeks, and 1 month.

Main Results

Thirty-three of 50 (66%) patients hospitalized with RSV received systemic steroids for a mean duration of 11 days. Those who received steroids more frequently wheezed and were less often febrile. There were no serious adverse events related to steroids and no significant differences in peak viral load, duration of RSV shedding, nasal cytokines, or lymphocyte subsets in patients treated with steroids and patients untreated with steroids. Antibody responses to RSV were slightly blunted in the steroid-treated group.

Conclusions

Short courses of systemic steroids in patients hospitalized with RSV infection did not affect viral load or shedding. Humoral immunity may be mildly diminished, and thus potential benefits of systemic steroids must be balanced against potential risks.

Incidence and risk factors of steroid-induced diabetes in patients with respiratory disease

Glucocorticoids are effective for treating several respiratory diseases. However, they can cause hyperglycemia. This study determined the incidence and risk factors of steroid-induced diabetes mellitus (S-DM) in patients treated with glucocorticoid for respiratory diseases. A retrospective study examined patients with respiratory diseases treated with a prednisolone-equivalent glucocorticoid dose exceeding 20 mg/day for at least 4 weeks between January 2003 and December 2008. Patients whose initial random glucose level exceeded 200 mg/dL or who had pre-existing diabetes were excluded. S-DM was defined as a fasting glucose concentration exceeding 126 mg/dL or a random glucose concentration exceeding 200 mg/dL at least twice after beginning steroid treatment. A total of 231 patients with respiratory diseases met the inclusion criteria. Their median age was 55 yr, and 139 were female. The median cumulative prednisolone-equivalent glucocorticoid dose was 4,965 mg, and the median duration of steroid treatment was 193 days. S-DM was diagnosed in 34 (14.7%) of 231 patients. Multivariate logistic regression identified older age (odds ratio 1.05, 95% confidence interval 1.02-1.09) as a risk factor for S-DM. S-DM is frequent among patients with respiratory diseases treated with glucocorticoid. Clinicians should be aware of the possibility of S-DM, especially among elderly patients.

Therapeutic management of allergic diseases

Allergic diseases are characterized by the activation of inflammatory cells and by a massive release of mediators. The aim of this chapter was to describe succinctly the modes of action, indications, and side effects of the major antiallergic and antiasthmatic drugs. When considering the ideal pharmacokinetic characteristics of a drug, a poorly metabolized drug may confer a lower variability in plasma concentrations and metabolism-based drug interactions, although poorly metabolized drugs may be prone to transporter-based disposition and interactions. The ideal pharmacological properties of a drug include high binding affinity, high selectivity, and appropriate association and dissociation rates. Finally, from a patient perspective, the frequency and route of administration are important considerations for ease of use.

Corticosteroid-induced adverse events in adults: frequency, screening and prevention

Corticosteroids represent the most important and frequently used class of anti-inflammatory drugs and are the reference therapy for numerous neoplastic, immunological and allergic diseases. However, their substantial efficacy is often counter-balanced by multiple adverse events. These corticosteroid-induced adverse events represent a broad clinical and biological spectrum from mild irritability to severe and life-threatening adrenal insufficiency or cardiovascular events. The purpose of this article is to provide an overview of the available data regarding the frequency, screening and prevention of the adverse events observed in adults during systemic corticosteroid therapy (topically administered corticosteroids are outside the remit of this review). These include clinical (i.e. adipose tissue redistribution, hypertension, cardiovascular risk, osteoporosis, myopathy, peptic ulcer, adrenal insufficiency, infections, mood disorders, ophthalmological disorders, skin disorders, menstrual disorders, aseptic necrosis, pancreatitis) and biological (i.e. electrolytes homeostasis, diabetogenesis, dyslipidaemia) events. Lastly, data about the prescription of corticosteroids during pregnancy are provided. This review underscores the absence of data on many of these adverse events (e.g. lipodystrophy, dyslipidaemia). Our intent is to present to practitioners data that can be used in a practical way to both screen and prevent most of the adverse events observed during systemic corticosteroid therapy.

Corticosteroid- and Anabolic Steroid—Induced Mental Status Disturbances

Corticosteroids and anabolic steroids can induce remarkably similar presentations in the mental status changes that they precipitate. Most individuals demonstrate affect and mood changes consistent with patients diagnosed with either bipolar or unipolar affective disorder. In addition, affective changes can be accompanied by delusions in the minority of subjects. Presentation of the drug-induced disorder is dose dependent. Patients experiencing corticosteroid-induced mental status changes are commonly ingesting the equivalent of approximately 60 mg/d of prednisone orally with the symptoms appearing in most patients within a week of starting the drug. In addition, women are more likely to experience these mental status changes. Subjects abusing anabolic steroids generally do not exhibit any mental status changes until a dose equivalent to intramuscular testosterone 600 mg/wk has been reached. Unlike corticosteroids, high-dose exposure of anabolic steroids is accompanied by increased aggressive behavior that is problematic from not only a medical but also a legal standpoint.

Corticosteroid-induced clinical adverse events: frequency, risk factors and patient's opinion

BACKGROUND

More than 50 years after the introduction of corticosteroids, few studies have focused on corticosteroid-induced adverse events after long-term systemic therapy.

OBJECTIVES

To assess the frequency, risk factors and patient's opinion regarding clinical adverse events occurring early during prednisone therapy.

PATIENTS AND METHODS

We conducted a cohort study in two French centres. All consecutive patients starting long-term (> oir = 3 months), high dosage (> or = 20 mg day(-1)) prednisone therapy were enrolled. The main clinical adverse events attributable to corticosteroids were assessed after 3 months of therapy, by comparison with baseline status. The patient's opinion regarding the disability induced by these adverse events was recorded. Risk factors of frequently observed adverse effects were identified by using logistic regression.

RESULTS

Eighty-eight patients were enrolled and 80 were monitored for at least 3 months (women 76%; mean age 59.1 +/- 18.7 years; giant cell arteritis 39%; mean baseline prednisone dosage 54 +/- 17 mg day(-1)). Lipodystrophy was the most frequent adverse event [63.0% (51.0-73.1)], was considered the most distressing by the patients and was most frequent in women and young patients. Neuropsychiatric disorders occurred in 42 patients [52.5% (41.0-63.8)], necessitating hospitalization in five cases. Skin disorders were noted by 37 patients [46.2% (35.0-57.7)] and were more frequent in women. Muscle cramp and proximal muscle weakness were reported by 32.5% (22.5-43.9) and 15% (8.0-24.7) of patients, respectively. Newly developed hypertension occurred in 8.7% (2.9-20.3) of patients. Lastly, 39% (19.7-61.4) of the premenopausal women reported menstrual disorders.

CONCLUSIONS

Lipodystrophy and neuropsychiatric disorders are common adverse events of long-term prednisone therapy and are particularly distressing for the patients concerned. The impact of these adverse events on adherence to corticosteroid therapy is not known.

Psychiatric adverse effects of corticosteroids

Psychiatric adverse effects during systemic corticosteroid therapy are common. Two large meta-analyses found that severe reactions occurred in nearly 6% of patients, and mild to moderate reactions occurred in about 28%. Although disturbances of mood, cognition, sleep, and behavior as well as frank delirium or even psychosis are possible, the most common adverse effects of short-term corticosteroid therapy are euphoria and hypomania. Conversely, long-term therapy tends to induce depressive symptoms. Dosage is directly related to the incidence of adverse effects but is not related to the timing, severity, or duration of these effects. Neither the presence nor the absence of previous reactions predicts adverse responses to subsequent courses of corticosteroids. Corticosteroid-induced symptoms frequently present early in a treatment cycle and typically resolve with dosage reduction or discontinuation of corticosterolds. In severe cases or situations in which the dose cannot be reduced, antipsychotics or mood stabilizers may be required. This review offers an approach to identifying and managing corticosteroid-induced psychiatric syndromes based on the type of symptoms and anticipated duration of corticosteroid treatment.

Safety of low dose glucocorticoid treatment in rheumatoid arthritis: published evidence and prospective trial data

Adverse effects of glucocorticoids have been abundantly reported. Published reports on low dose glucocorticoid treatment show that few of the commonly held beliefs about their incidence, prevalence, and impact are supported by clear scientific evidence. Safety data from recent randomised controlled clinical trials of low dose glucocorticoid treatment in RA suggest that adverse effects associated with this drug are modest, and often not statistically different from those of placebo.

Methods to avoid infections in patients with inflammatory bowel disease

Infections have been reported in patients with inflammatory bowel disease (IBD), especially in association with anti-inflammatory and immunomodulatory medications used to treat IBD. Unfortunately, there is a dearth of information on infectious complication risk in patients with IBD. This review describes infectious complications reported in patients with IBD and provides a framework for future studies to assess potential risk factors and incidence for infection. Recommendations are also provided for prevention of infection.

Asthma severity, psychiatric morbidity, and quality of life: correlation with inhaled corticosteroid dose

OBJECTIVES

Psychiatric phenomena in asthma has been debated for some time. Inhaled corticosteroids (ICS) are a significant part of treatment. We attempted to quantify the prevalence of psychiatric morbidity relative to asthma severity, quality of life (QOL), and ICS dose.

DATA SOURCES

Fifty asthmatic patients (18 > or = X < or =75 years) on ICS, attending an urban clinic had asthma and ICS dose stratified by symptom severity and preparation potency. Peak flow and forced expiratory volume in 1 second (FEV1) were measured. Patients completed general QOL and disease-specific QOL questionnaires, along with psychiatric rating scales.

RESULTS

Patients (n = 50) clustered in the 40-59 year range (n = 27, 54%) and were predominantly female (n = 44, 88%) Hispanics (n = 30, 60%), with mild-moderate asthma (n = 18, 36%) and on low-dose ICS (n = 22, 44%). FEV1 ranged from 32 to 123 (mean 76.98, SE 3.01). Peak flow ranged from 210 to 590 (mean 407.83, SE 13.24). Prevalence of anxiety and depressive symptoms were higher than expected (Kendall's tau-c, n = 50, P < .01). Independently, high ICS dose and asthma severity correlated directly with all measures of psychiatric morbidity (Pearson's r0.781, P < .01). High ICS dose correlated inversely with SF-36 Mental Component Scale (Pearson's r0.681, P < .01) and directly with FEV1 and peak flow when age/sex adjusted (Spearman's rho: 0.660, P < .001).

CONCLUSIONS

Psychiatric morbidity is more prevalent in this population and impacts negatively on QOL. Use of high-dose ICS benefited pulmonary function and "physical" QOL, yet may have negatively affected patients' mental well-being. Longitudinal follow-up, extension of sample size, and better study control would allow closer approximation of possible negative associations with ICS.

Steroid psychosis: a review

This review is built upon a time-framed perspective to unfold the growth of evidence and the shifting of focus from primary affective short-term reactions to later findings of cognitive deficits and possible permanent impairment linked to steroid treatment. An incidence related to dosage has been documented and delirium and withdrawal symptoms have been reported in later studies. A hypothesis of sensitization process with multiple course of steroids has been proposed with the reporting of recurrent cases. The issue of individual risk appears unsettled while management of psychiatric reactions to steroids has shifted toward prophylactic use of lithium.

Quantification of the Risk of Corticosteroid-induced Diabetes Mellitus Among the Elderly

We conducted a population-based cohort study using administrative databases to quantify the association between oral and inhaled corticosteroid use and onset of diabetes mellitus in the elderly. Proton pump inhibitor (PPI) users were used as a control group. Relative to PPI users (N = 53,845), oral corticosteroid users (N = 31,864) were more likely to develop diabetes (adjusted rate ratio [aRR], 2.31; 95% confidence interval [95% CI], 2.11 to 2.54); however, inhaled corticosteroid users (N = 38,441) were not (aRR, 1.03; 95% CI, 0.93 to 1.14). The estimated number needed to harm for continuous use of oral corticosteroids relative to PPIs over 1, 2, and 3 years of use were 41, 23, and 16, respectively.

Corticosteroids in chronic obstructive pulmonary disease. Clinical benefits and risks

The use of systemic and inhaled corticosteroids for COPD has increased appreciably over the past 20 years. Clearer indications for corticosteroid therapy in COPD are beginning to emerge as the results from large clinical trials become available. Systemic corticosteroids are only modestly effective for acute COPD exacerbations, increase the risk for hyperglycemia, and should be given for no more than 2 weeks. The efficacy of long-term systemic corticosteroid therapy has not been adequately evaluated in this patient population. If longer term use of systemic steroids in COPD should be found to be useful, this conclusion would have to be weighed against the risk for serious adverse effects. High doses of inhaled corticosteroids cause a small sustained increase of the FEV1 in patients with mild and moderately severe COPD, but they do not slow the rate of FEV1 decline. Based on analyses of secondary outcome, inhaled corticosteroids may improve the respiratory symptoms and decrease the number and severity of COPD exacerbations in patients with more advanced disease. Low doses of inhaled corticosteroids appear to be safe, but there is growing awareness that higher doses may not be so benign.

Inhaled corticosteroid therapy is safe in tuberculin-positive asthmatic children

BACKGROUND

Although treatment with oral corticosteroids can cause reactivation of latent Mycobacterium tuberculosis (TB) infection in purified protein derivative (PPD)-positive individuals with no evidence of clinical disease, little is known about the effects of inhaled corticosteroids in this respect.

OBJECTIVE

This study was undertaken to assess whether inhaled corticosteroid (CS) therapy reactivates latent TB infection in PPD-positive asthmatic children.

METHOD

We studied 32 PPD skin test-positive (> or =10 mm) children [age (mean +/- SD), 7.9 +/- 4.1 years] with no family history and no evidence of TB infection on chest radiograms who were receiving inhaled budesonide for the treatment of asthma. They were further evaluated with thorax computed tomography (CT) and erythrocyte sedimentation rate and closely observed for an additional 9 months.

RESULTS

At enrollment the mean diameter of PPD reaction was 12.8 +/- 2.7 mm. The mean duration of inhaled CS treatment and the mean cumulative CS dose were 9.8 +/- 7.6 months and 275 +/-199 mg, respectively. Thorax CT studies revealed mediastinal lymph nodes in 7 of the 32 patients. There was no significant difference between children with and without mediastinal lymph nodes according to age, gender, size of PPD skin testing, erythrocyte sedimentation rate and duration and cumulative CS dose of inhaled budesonide therapy before study. A second thorax CT was obtained 9 months later in those 7 patients with lymphadenopathy (additional mean cumulative CS dose, 222.57 mg). There was no change in the size of their lymph nodes.

CONCLUSION

Long term inhaled budesonide therapy appears to be safe in PPD-positive asthmatic children.

Inhaled vs oral steroids for adults with chronic asthma

OBJECTIVES

To determine therapeutically equivalent doses of inhaled versus oral steroids for adults with chronic asthma.

SEARCH STRATEGY

The Cochrane Airways Group trials register was searched using the terms: (drug delivery systems OR ((nebuli* OR inhal* OR MDI) AND oral*)) AND ( steroid* OR corticosteroid* OR glucocorticoid* OR beclomethasone OR betamethasone OR fluticasone OR cortisone OR dexamethasone OR hydrocortisone OR prednisolone OR prednisone OR triamcinolone).

SELECTION CRITERIA

Randomised controlled trials were selected of at least 4 weeks duration and included patients over the age of 15 years with chronic asthma. Trials compared inhaled steroids and oral prednisolone or prednisone; where the maximum dose for inhaled steroids was 2000 mcg/day and prednisolone 60 mg (on alternate days).

DATA COLLECTION AND ANALYSIS

Two independent reviewers screened 1285 titles and abstracts from the electronic search, bibliography searches and other contacts. Of these, 10 trials met previously defined inclusion criteria. Two reviewers independently extracted study characteristics, and outcome measures.

MAIN RESULTS

All trials were small and no data could be pooled. Carry-over effects were present in at least one cross-over trial. Data from six trials produced the same pattern, in which prednisolone 7.5-12 mg/day appeared to be as effective as inhaled steroid 300-2000 mcg/day. In two trials, inhaled steroid 300-400 mcg/day was more effective than prednisolone 5 mg/day. All doses of inhaled steroid appeared to be more effective than alternate day doses of prednisolone up to 60 mg on alternate days. Side-effect data were reported too variably to permit comparisons. A 30% incidence was reported in one study in patients receiving prednisolone 5 mg/day, none were reported in patients on inhaled steroids.

REVIEWER'S CONCLUSIONS

A daily dose of prednisolone 7.5-10 mg/day appears to be equivalent to moderate-high dose inhaled corticosteroids. Side-effects may be present on low doses, so if there is no alternative to oral steroids, the lowest effective dose should be prescribed.

The psychiatric side effects of corticosteroids

LEARNING OBJECTIVES

Readers will learn the importance of psychiatric symptomatology with corticosteroid drug therapy, especially when combined with other medications.

DATA SOURCES

A brief history of corticosteroid use over the last five decades was complied utilizing MEDLINE and PSYCHOINFO as sources of information which include peer-reviewed research articles, case studies, and relevant reviews in English.

CONCLUSION

Corticosteroids are routinely prescribed for a variety of allergic and immunologic illnesses. Psychiatric side effects from corticosteroids include mania, depression and mood disturbances. Psychiatric symptoms usually occur within the first two weeks of corticosteroid therapy and seem to be dose related. Treatment with lithium or antipsychotics may be helpful. Physicians should carefully monitor patients for psychiatric and cognitive side effects of corticosteroid use.

Effect of systemic glucocorticoids on exacerbations of chronic obstructive pulmonary disease. Department of Veterans Affairs Cooperative Study Group

BACKGROUND AND METHODS

Although their clinical efficacy is unclear and they may cause serious adverse effects, systemic glucocorticoids are a standard treatment for patients hospitalized with exacerbations of chronic obstructive pulmonary disease (COPD). We conducted a double-blind, randomized trial of systemic glucocorticoids (given for two or eight weeks) or placebo in addition to other therapies, for exacerbations of COPD. Most other care was standardized over the six-month period of follow-up. The primary end point was treatment failure, defined as death from any cause or the need for intubation and mechanical ventilation, readmission to the hospital for COPD, or intensification of drug therapy.

RESULTS

Of 1840 potential study participants at 25 Veterans Affairs medical centers, 271 were eligible for participation and were enrolled; 80 received an eight-week course of glucocorticoid therapy, 80 received a two-week course, and 111 received placebo. About half the potential participants were ineligible because they had received systemic glucocorticoids in the previous 30 days. Rates of treatment failure were significantly higher in the placebo group than in the two glucocorticoid groups combined at 30 days (33 percent vs. 23 percent, P=0.04) and at 90 days (48 percent vs. 37 percent, P=0.04). Systemic glucocorticoids (in both groups combined) were associated with a shorter initial hospital stay (8.5 days, vs. 9.7 days for placebo, P=0.03) and with a forced expiratory volume in one second that was about 0.10 liter higher than that in the placebo group by the first day after enrollment. Significant treatment benefits were no longer evident at six months. The eight-week regimen of therapy was not superior to the two-week regimen. The patients who received glucocorticoid therapy were more likely to have hyperglycemia requiring therapy than those who received placebo (15 percent vs. 4 percent, P=0.002).

CONCLUSIONS

Treatment with systemic glucocorticoids results in moderate improvement in clinical outcomes among patients hospitalized for exacerbations of COPD. The maximal benefit is obtained during the first two weeks of therapy. Hyperglycemia of sufficient severity to warrant treatment is the most frequent complication.

Systemic Corticosteroids in Chronic Obstructive Pulmonary Disease Exacerbations (SCCOPE): rationale and design of an equivalence trial. Veterans Administration Cooperative Trials SCCOPE Study Group

The Systemic Corticosteroids in Chronic Obstructive Pulmonary Disease Exacerbations Trial (SCCOPE) was a randomized, double-blind, placebo-controlled, multicenter trial sponsored by the U.S. Department of Veterans Affairs Cooperative Studies Program. Its principal purpose was to determine whether withholding systemic corticosteroids in patients hospitalized for exacerbations of chronic obstructive pulmonary disease (COPD) who were treated with other usual therapy resulted in a clinically significant increase in the rate of treatment failure. Because placebo was compared to a standard therapy, the study was designed as an equivalence trial. If corticosteroids proved effective, the study would also determine whether a short course was as effective as a long one. SCCOPE was to enroll up to 1100 subjects from more than 20 Veterans Administration Medical Centers over 3 years. Patients were screened shortly after hospital admission for acute exacerbation of COPD. Principal criteria for eligibility were age of 50 years or older, smoking history of 30 pack-years or more, clinical diagnosis of COPD as opposed to asthma, nonuse of systemic corticosteroids in the previous 30 days, and forced expiratory volume in 1 sec (FEV1) of 1500 ml or less. Eligible subjects were randomized to one of three treatment arms: (1) short course (2 weeks) of systemic corticosteroids, (2) long course (8 weeks) of systemic corticosteroids, or (3) placebo. We standardized most other aspects of care. We followed patients for 6 months. The primary endpoint of the study was treatment failure, defined as death, intubation with mechanical ventilation, hospital readmission for COPD, or intensification of pharmacologic therapy. Secondary endpoints included length of hospital stay, changes in FEV1, and changes in dyspnea score. We also evaluated possible adverse effects from systemic corticosteroids.

The risks of systemic corticosteroid use

Because of their potent antiinflammatory and immunosuppressive properties, systemic corticosteroids are used to modify a vast array of diseases. This class of drugs, however, has the potential to produce multiple adverse effects presenting the dermatologist with difficult decisions in the management of patients with potentially steroid responsive disorders. This article reviews the side effects of systemic corticosteroids, comments on strategies to minimize these side effects, as well as, outlining suggested mechanisms by which physicians may minimize the risks of medical legal consequences owing to adverse reactions to these drugs.

Glucocorticoid medication, memory and steroid psychosis in medical illness

Steroid psychosis, including associated cognitive changes, is infrequent with short-term low-dose GC treatment, especially if only major objectively discernible effects are assessed. With long-term or high-dose treatment, however, or if milder subjectively discernible symptoms are also assessed, the incidence may be quite high. In lupus cerebritis, the differentiation between cognitive difficulties secondary to the underlying illness, which might warrant more aggressive GC treatment, versus those secondary to GC treatment itself, which might warrant dosage reduction, may be problematic, but certain guidelines have been proposed. Although GCs are widely prescribed and represent a clinically important class of medication, their deleterious effects may also be considerable. Glucocorticoids have prominent effects on central nervous system biochemistry and electrophysiology, and recent reports suggest they make certain hippocampal neurons more vulnerable to a variety of metabolic insults. Indeed, the clinical literature reviewed here is consistent with a disruption of hippocampus-dependent memory function (perhaps in conjunction with other areas of dysfunction), although in most cases the disruption is relatively mild and, in the vast majority, if not all cases, is reversible. From a clinical prospective, it is important to discuss potential neuropsychiatric side effects with patients before prescribing GC treatment. A greater understanding of the risk factors for experiencing SP and of its underlying mechanisms will lead to more informed clinical decision making and to a greater understanding of the role exogenous, and perhaps endogenous, GCs play in human cognition and behavior.

Adverse effects of corticosteroid therapy for COPD. A critical review

Inhaled and systemic corticosteroids are commonly prescribed for the treatment of COPD. Despite their frequent use, there is insufficient evidence regarding efficacy of steroid therapy in COPD. While awaiting the results of more definitive prospective trials, the clinician must evaluate whether the benefits of such therapy outweigh the potential for adverse events. This is particularly pertinent in the population of patients with COPD who generally are older, less active, and have significant tobacco use histories, all of which may place them at greater risk for adverse effects. In this review, we examine the current scientific evidence supporting the many purported adverse systemic effects associated with the use of corticosteroids in the treatment of COPD.

Corticosteroid-induced delirium and dependency

A case of a patient with chronic lung disease who developed an addiction pattern of corticosteroid dependency is described in which steroid-induced delirium also developed. The rare phenomenon of corticosteroid dependency is discussed as well as the phenomenology and possible mechanisms of steroid-induced delirium.

Corticosteroids: do they damage the cardiovascular system?

Since their introduction for the treatment of rheumatoid arthritis, corticosteroids have become widely used as effective agents in the control of inflammatory diseases. Although there have been undoubted benefits upon mortality in diseases such as systemic lupus erythematosus, many patients survive only to suffer a high incidence of premature atherosclerosis. There is also evidence of increased rates of vascular mortality in other corticosteroid-treated diseases, such as rheumatoid arthritis, reversible airways obstruction and transplant recipients. Possible mechanisms of damage include elevated blood pressure, impaired glucose tolerance, dyslipidaemia, and imbalances in thrombosis and fibrinolysis. This paper reviews the clinical evidence supporting the contention that there is an excess cardiovascular mortality in steroid-treated patients and the underlying mechanisms, and points to further areas of research.

Corticosteroids and tuberculosis

Common for all older studies is the use of less potent anti-tuberculosis chemotherapy as compared with the present. The results of these studies cannot without reservation be used in the present setting. The newer, prospective, randomized placebo-controlled trials include rather few patients and their number is limited. The results must be interpreted carefully. There is no reason to give prophylactic isoniazide treatment to Mantoux-positive patients or patients with earlier tuberculosis who start treatment with corticosteroids. If allergic reactions to one of the antituberculous drugs emerge during therapy, the treatment can, if necessary, be continued if corticosteroids are added. Pericardial tuberculosis and atelectasis in children with endobronchial tuberculosis should be treated with corticosteroids, as can pleural disease with prolonged fever and exudation. Cases of severe pulmonary tuberculosis may be treated with supplementary steroids. The effect seems modest. Patients with tuberculous meningitis, stages II and III seem to benefit from corticosteroid-treatment.

Slight steroid-sparing effect of intravenous immunoglobulin in children and adolescents with moderately severe bronchial asthma

Twenty subjects (aged 6-20 years) with moderately severe bronchial asthma participated in an open controlled trial with intravenous immunoglobulin (IVIG) given as five monthly infusions with a mean dose of 0.8 g/kg body weight. A follow-up was performed 4 and 14 months after the treatment period. Nine of 14 children in the treatment group completed the trial. Two children experienced severe headache after the first infusion, another two patients were taken off the study for reasons unrelated to the IVIG therapy, and one patient dropped out from lack of motivation. In six of the IVIG-treated children, there was a reduction in the daily intake of inhaled steroids at an unchanged or reduced histamine reactivity. Of the remaining three children, two showed a reduction in bronchial hyperreactivity, but their steroid dose was not reduced. Six patients participated in a reference group to determine seasonal variations of symptoms. One of them improved during the study period, and the condition of the other five deteriorated, as indicated by increased medication without reduced histamine reactivity. After 14 months, there were no significant differences in clinical symptoms, nor in sensitivity to histamine between the treated patients and the controls, as the condition had improved also in the latter. We have thus been able to confirm, in a group larger than those in previously published reports, some clinical improvement of asthma by IVIG therapy at a lower dose than previously used and in children with only moderately severe disease. The effect was still present 4 months after the termination of IVIG therapy but not after 14 months.(ABSTRACT TRUNCATED AT 250 WORDS)

Clinical pharmacology of asthma. Implications for treatment

The past 10 years have seen three important changes in the philosophy of managing asthma. First, histological studies using fibreoptic bronchoscopy have led to the recognition that asthma is an inflammatory condition of the bronchial mucosa and is not simply caused by smooth muscle spasm. Secondly, there has been some disenchantment with the long term use of regular beta 2-adrenergic agonists as these agents do not appear to control bronchial inflammation and have been associated with deaths from asthma. Thirdly, there has been a general shift away from physician-centred management towards patient-oriented management plans. These three separate strands have led to the development of regional and international consensus documents that emphasise the use of regular anti-inflammatory treatment to control bronchial inflammation and reduce symptoms. With the emphasis on finding the minimum amount of treatment, several traditional anti-asthma medications have been downgraded in importance. The introduction of self-management plans is to be welcomed, but it is important that these new strategies for treating asthma are properly evaluated so that the benefits they confer can be ascertained and maximised.

Corticosteroids and tuberculosis: risks and use as adjunct therapy

Adjunct therapy with corticosteroids, in conjunction with antituberculous drugs, may be appropriate in particular forms of tuberculosis. Prospective controlled trials have shown a benefit in tuberculous meningitis, pericardial and pleural disease. Although benefit has been shown in pleural disease, adjunct therapy is not routinely required unless there are significant systemic symptoms of fever or a particularly large effusion. It has been recommended in the past that corticosteroids should be used routinely in endobronchial TB, especially pediatric disease, but our recent experience has been that such therapy is not usually required. Although corticosteroid therapy is sometimes recommended in extensive pulmonary disease there are no controlled trials, in the modern drug era, to support such therapy. Where adrenal suppression is a concern supplemental corticosteroids are indicated. Fever, be it drug-related or from systemic disease, sometimes requires suppression with corticosteroids. The usual dose required is 40-60 mg of prednisone orally daily for 4-6 weeks depending on the system involved, with tapering doses of prednisone subsequent to this. Local corticosteroid therapy of BCG-related keloid reactions may also be useful. Anecdotal reports suggest immune suppression with corticosteroids predisposes to tuberculosis but retrospective studies on patients taking, in general, low doses of prednisone have not confirmed this risk. Corticosteroid interaction with the oral birth control pill and rifampin need also to be accounted for in prescribing these agents.

Pulmonary tuberculosis in patients treated with inhaled beclomethasone

Inhaled beclomethasone dipropionate (BDP) has been used with few side-effects in the treatment of bronchial asthma for 2 decades. Until now the manifestation of tuberculosis (TB) in patients on inhaled BDP has not been reported. Eight patients with allergic asthma, of a total of 548 asthmatics (1.46%) seen over a 2-year period, developed active TB following the use of inhaled BDP. All were sputum-positive for acid-fast bacilli (AFB) on smear and/or culture, all responded well to a combination of anti-TB drugs, and none showed evidence of immunological or pituitary-adrenal suppression. Two patients agreed to a repeat administration of BDP; both developed TB again within 2 weeks and are again on anti-TB treatment.

Corticosteroid therapy for rheumatoid arthritis. Benefits and limitations

Oral corticosteroids, despite their potential side effects, have a select role in the treatment of rheumatoid arthritis. For articular disease, these drugs must be targeted to short-term goals, such as symptom relief. Close attention to the indications and potential hazards of steroid therapy may ensure optimal benefit and reduced risk. Intra-articular steroid injections can provide local symptomatic relief when only one or a few joints are swollen. Septic arthritis is most important to exclude before injection of a joint. Complications of intra-articular injection are few, and relief may be long-lasting.

Controlled trial of natamycin in the treatment of allergic bronchopulmonary aspergillosis

Allergic bronchopulmonary aspergillosis often requires treatment with oral corticosteroids to control the host response to Aspergillus fumigatus. In a double blind study 25 patients with allergic bronchopulmonary aspergillosis taking maintenance oral corticosteroids were randomly allocated to receive 5 mg natamycin or placebo by nebuliser twice daily for one year. The primary aim of the study was to assess the steroid sparing potential of natamycin. Standardised reductions in corticosteroid dosage were therefore undertaken every five weeks, unless clinically contraindicated. Five patients were withdrawn in the first four months: two (1 natamycin, 1 placebo) died, two (1 natamycin, 1 placebo) had suspected drug reactions, and one (natamycin) was non-compliant. The pretreatment characteristics of the 20 patients (10 in each group) who completed the study were similar, 17 (9 natamycin, 8 placebo) having evidence of recent disease activity. At the end of the study prednisolone dose had been reduced by a similar amount in each group (median natamycin 2.25 mg, placebo 2.5 mg). Evidence of disease activity during the study year (transient shadowing on the chest radiograph, blood eosinophilia, or increases in antibodies to A fumigatus, or any combination of these) was observed in similar numbers of patients in each group (5 natamycin, 7 placebo). There was no evidence that natamycin conferred benefit on these patients with allergic bronchopulmonary aspergillosis.
