Nonassociation of adrenocorticosteroid therapy and peptic ulcer

Risk factors for gastrointestinal complications during glucocorticoid therapy in internal medicine inpatients: a real-world retrospective analysis

BACKGROUND

The risk factors for gastrointestinal complications during glucocorticoid therapy in internal medicine inpatients are rarely reported. This study aimed to investigate the risk factors for gastrointestinal complications in internal medicine patients using glucocorticoids.

METHODS

Internal medicine inpatients receiving glucocorticoid therapy from February 2023 to September 2023 were included. Gastrointestinal complications were identified by careful review of the electronic medical records of these patients. The risk factors for gastrointestinal complications during glucocorticoid therapy were analyzed by univariable and multivariable logistic regression. Receiver operating characteristic (ROC) curve with Youden's index was used to determine the best cutoff point of the identified continuous variables.

RESULTS

Of the 960 inpatients included, 88 had gastrointestinal complications, with the most common complications including 27 (30.7%) with abdominal discomfort, 26 (29.5%) with acid regurgitation and heartburn, and 14 (15.9%) with asymptomatic positive fecal occult blood. Multiple logistic regression analysis showed that age ≥ 65 years [OR = 2.014, 95% CI (1.096, 3.703), p = 0.024], history of gastroesophageal reflux disease (GERD) [OR = 1.810, 95% CI (1.009, 3.250), p = 0.047], history of peptic ulcer (PU) [OR = 5.636, 95% CI (1.505, 21.102), p = 0.010], maximum dose of glucocorticoids [OR = 1.003, 95% CI (1.001, 1.004), p = 0.001], and nonsteroidal anti-inflammatory drugs (NSAIDs) [OR = 2.788, 95% CI (1.023, 7.597), p = 0.045] were associated with more gastrointestinal complications during glucocorticoid therapy in internal medicine inpatients. ROC curve analysis revealed that when the maximum dose of glucocorticoids was greater than 160 mg, gastrointestinal complications were more likely to occur.

CONCLUSIONS

The study shows that age ≥ 65 years, history of GERD, history of PU, maximum dose of glucocorticoids, and NSAIDs are associated with more gastrointestinal complications during glucocorticoid therapy in internal medicine inpatients. Multidisciplinary teams, including physicians, pharmacists, and nurses, should consider increased monitoring to inpatients with high-risk factors.

Juvenile dermatomyositis complications: navigating gastrointestinal perforations and treatment challenges, a case report

Juvenile dermatomyositis (JDM) is a rare autoimmune disorder with multi-system involvement, often presenting with a heliotrope rash, Gottron's papules, and proximal muscle weakness. JDM patients with anti-nuclear matrix protein 2 (anti-NXP2) positivity tend to have more severe manifestations, including a higher risk of gastrointestinal (GI) complications such as dysphagia, intestinal motility changes, edema, malabsorption, ulcers, and perforations. These complications are associated with poor outcomes and high mortality rates, particularly in patients with anti-NXP2 positivity. A case is presented of a 12-year-old girl with JDM who developed multiple GI perforations after being treated with high-dose methylprednisolone. Despite multiple surgical attempts, the patient experienced continued leakage and new perforations. The treatment approach was shifted to include jejunostomy, plasma exchanges, fresh frozen plasma support, and tofacitinib, leading to gradual improvement in muscle strength and reduction in inflammation. GI involvement in JDM is a significant concern due to its association with poor prognosis and high mortality. The use of high-dose glucocorticoids must be carefully considered in JDM patients with GI involvement, as they may contribute to the development of perforations and complicate treatment. A combination of plasma exchange, fresh frozen plasma support, low-dose glucocorticoids, and Janus kinase inhibitors may offer a safer treatment strategy for managing refractory JDM with GI complications. The case highlights the importance of a multidisciplinary approach to treatment and the need for further research to determine the necessity of high-dose glucocorticoid therapy following GI involvement in JDM.

Glucocorticoid Treatment in Acute Respiratory Distress Syndrome: An Overview on Mechanistic Insights and Clinical Benefit

Acute lung injury/acute respiratory distress syndrome (ALI/ARDS), triggered by various pathogenic factors inside and outside the lungs, leads to diffuse lung injury and can result in respiratory failure and death, which are typical clinical critical emergencies. Severe acute pancreatitis (SAP), which has a poor clinical prognosis, is one of the most common diseases that induces ARDS. When SAP causes the body to produce a storm of inflammatory factors and even causes sepsis, clinicians will face a two-way choice between anti-inflammatory and anti-infection objectives while considering the damaged intestinal barrier and respiratory failure, which undoubtedly increases the difficulty of the diagnosis and treatment of SAP-ALI/ARDS. For a long time, many studies have been devoted to applying glucocorticoids (GCs) to control the inflammatory response and prevent and treat sepsis and ALI/ARDS. However, the specific mechanism is not precise, the clinical efficacy is uneven, and the corresponding side effects are endless. This review discusses the mechanism of action, current clinical application status, effectiveness assessment, and side effects of GCs in the treatment of ALI/ARDS (especially the subtype caused by SAP).

Drug-Associated Gastropathy: Diagnostic Criteria

Drugs are widely used to treat different diseases in modern medicine, but they are often associated with adverse events. Those located in the gastrointestinal tract are common and often mild, but they can be serious or life-threatening and determine the continuation of treatment. The stomach is often affected not only by drugs taken orally but also by those administered parenterally. Here, we review the mechanisms of damage, risk factors and specific endoscopic, histopathological and clinical features of those drugs more often involved in gastric damage, namely NSAIDs, aspirin, anticoagulants, glucocorticosteroids, anticancer drugs, oral iron preparations and proton pump inhibitors. NSAID- and aspirin-associated forms of gastric damage are widely studied and have specific features, although they are often hidden by the coexistence of Helicobacter pylori infection. However, the damaging effect of anticoagulants and corticosteroids or oral iron therapy on the gastric mucosa is controversial. At the same time, the increased use of new antineoplastic drugs, such as checkpoint inhibitors, has opened up a new area of gastrointestinal damage that will be seen more frequently in the near future. We conclude that there is a need to expand and understand drug-induced gastrointestinal damage to prevent and recognize drug-associated gastropathy in a timely manner.

Biases in reporting of adverse effects in clinical trials, and potential impact on safety assessments in systematic reviews and therapy guidelines

BACKGROUND

Clinical trials are an important source of adverse effects data, including analyses in systematic reviews and recommendations in therapy guidelines. Trial publication bias may have profound effects on safety perceptions. This MiniReview presents and discusses biases in reporting of safety data in clinical trials and the implications for systematic reviews and guidelines.

OBJECTIVES

The objectives of this work are to analyse risk of gastrointestinal bleeding in systemic corticosteroid trials and to assess adverse effects reporting in a fluoxetine trial in depression (Treatment for Adolescents With Depression Study [TADS]) and descriptions of adverse effects in adolescent depression therapy guidelines.

METHODS

We performed literature reviews and descriptive analyse of clinical trials with corticosteroids, and publications from the TADS trial. Risk of gastrointestinal bleeding from corticosteroids was analysed by meta-analysis.

FINDINGS

Gastrointestinal bleeding definitions varied considerably between trials. The incidence was significantly increased in hospitalized, but not in ambulant, patients compared to placebo. We identified several biases concerning TADS safety reporting, including severity thresholds and nonpublication of most adverse effects data beyond the initial 12 weeks. Therapy guidelines on adolescent depression mentioned suicidality risk, but many failed to mention other adverse effects.

CONCLUSIONS

We identified several pitfalls in adverse effects reporting in clinical trials. These include heterogeneous disease definitions, reporting thresholds, and incomplete reporting. Trial bias may have great impact on risk assessments in systematic reviews and meta-analyses.

Prevention of Adverse Outcomes and Treatment Side Effects in Patients with Neuromuscular Disorders

In this article, we review prevention of serious adverse clinical outcomes and treatment side effects in patients with neuromuscular disorders including myopathies and myasthenia gravis. While neither of these entities is preventable, their course can often be modified, and severe sequelae may be prevented, with the identification of risk factors and proactive attention toward treatment planning.

Endocrine Disorders in Autoimmune Rheumatological Diseases: A Focus on Thyroid Autoimmune Diseases and on the Effects of Chronic Glucocorticoid Treatment

Autoimmune rheumatological diseases’ incidence and prevalence have risen over the last decades and they are becoming increasingly important worldwide. Thyroid autoimmune diseases share with them an imbalance in the immune system that lead to a pro-inflammatory environment. Usually this is the result of a multi-factorial process. In fact, it includes not only a possible genetic predisposition, but also environmental causes like microbiota dysbiosis, diet rich in processed foods, exposure to toxicants and infections. However, many aspects are currently under study. This paper aims to examine the factors that participate in the developing of rheumatological and thyroid autoimmune diseases. Moreover, as glucocorticoids still represent a leading treatment for systemic autoimmune rheumatological diseases, our secondary aim is to summarize the main effects of glucocorticoids treatment focusing on iatrogenic Cushing’s syndrome and glucocorticoids’ withdrawal syndrome.

The Use of Higher Dose Steroids Increases the Risk of Rebleeding After Endoscopic Hemostasis for Peptic Ulcer Bleeding

BACKGROUND

Previous studies have shown that several factors such as hemodynamic instability at admission are risk factors for rebleeding of peptic ulcer bleeding. However, whether steroid use increases the risk of rebleeding remains elusive.

AIMS

This study aimed to clarify the risk factors for rebleeding after endoscopic hemostasis for peptic ulcer bleeding.

METHODS

A total of 185 patients who underwent endoscopic hemostasis for peptic ulcer bleeding at our institution between 2005 and 2017 were retrospectively analyzed. We evaluated factors, including comorbid conditions, in-hospital onset, and steroid use, associated with rebleeding by logistic regression analysis. In addition, we investigated the association between the dose of steroids and rebleeding.

RESULTS

The rebleeding rate after endoscopic hemostasis for peptic ulcer bleeding was 14.6%. In the multivariate analysis, the independent risk factors for rebleeding were steroid use (odds ratio 4.56, p = 0.015), multiple ulcers (4.43, p = 0.005), number of comorbidities ≥ 3 3.18, p = 0.026), hemodynamic instability (3.06, p = 0.039), and number of comorbidities ≥ 3 (2.93, p = 0.047). Furthermore, the use of higher dose steroids (≥ 20 mg per day in prednisolone; 10.55, p = 0.002), but not lower dose (< 20 mg per day in prednisolone), was an independent risk factor for rebleeding in the multivariate analysis. The relationship between steroid use and rebleeding was observed in a dose-dependent manner (p for trend = 0.002).

CONCLUSIONS

This study first revealed that using higher dose steroids was an independent risk factor for rebleeding after endoscopic hemostasis for peptic ulcer bleeding, with a dose-response relation.

Corticosteroids and risk of gastrointestinal bleeding in critically ill adults: Protocol for a systematic review

BACKGROUND

Corticosteroids are frequently prescribed to critically ill patients. However, their use may increase the risk of gastrointestinal (GI) bleeding, which is associated with morbidity and mortality. Accordingly, we aim to assess whether continued administration of corticosteroids for >24 hours increases the rate of GI bleeding in adult critically ill patients compared to placebo or no treatment.

METHODS/DESIGN

We will conduct a systematic review of randomized clinical trials with meta-analysis and trial sequential analysis. The participants will be adult (as defined in the included trials) critically ill patients. The intervention will be any corticosteroid administered systematically for >24 hours and the comparator will be placebo or no treatment. The primary outcome will be rate of clinically important GI bleeding. We will systematically search EMBASE, MEDLINE, Medline In-Process, Cochrane Library, Epistemonikos and trial registries for relevant literature, as well as perform a hand search. We will follow the recommendations by the Cochrane Collaboration and the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement. The risk of systematic errors (bias) and random errors will be assessed and the overall quality of evidence will be evaluated using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach.

DISCUSSION

The risk of GI bleeding in adult critically ill patients treated with corticosteroids is unknown. Hence, there is need for a robust systematic review to assess this risk and provide clinicians with a clearer understanding of the strength and limitations of existing data.

Critical evaluation of papers reviewing controlled clinical trials in homoeopathy

An analysis was made of papers reviewing controlled clinical trials designed to assess efficacy of homoeopathic treatment strategies, the aim being to demonstrate selective and critical assessment of such papers. The papers were systematically collected and evaluated for content and quality using predefined criteria, finally comparing the results. 9 of 41 papers considered in detail after screening the literature met the criteria for inclusion in the analysis. Each considered between 22 and 107 trials. 7 papers met 2 or less of the predefined quality criteria, one met 6 and one 8 criteria. Only 1 of the papers allowed full representation and reproducible evaluation of treatment strategies for the controlled clinical studies considered in that paper. The analysis has shown that review papers must clearly specify issues, objectives, methods of literature screening and quality assessment.

The Clinical Utility and Safety of a New Strategy for the Treatment of Refractory Kawasaki Disease

OBJECTIVE

To assess the clinical utility and safety of a strategy for refractory Kawasaki disease, defined by Egami score ≥3.

STUDY DESIGN

First-line treatment was with intravenous methylprednisolone (30 mg/kg, 2 hours, 1 dose) plus intravenous immunoglobulin (2 g/kg, 24 hours) treatment. Patients resistant to first-line treatment received additional intravenous immunoglobulin as a second-line treatment. Patients resistant to second-line treatment who had received Bacillus Calmette-Guérin vaccination 6 months earlier were treated with infliximab; otherwise, plasma exchange was performed. A total of 71 refractory patients with Kawasaki disease (median age: 2.4 years) of 365 patients with Kawasaki disease were treated according to our strategy from April 2007 to April 2016. Treatment resistance was defined as a persistent fever at 36 hours after treatment. We evaluated coronary artery lesions at the time of the diagnosis, at 1 month, and at 1 year after the diagnosis in accordance with the American Heart Association guidelines and the criteria of the Japanese Ministry of Health, Labour, and Welfare.

RESULTS

First-line therapy was effective for 58 of 71 patients (81.6%), and second-line therapy was effective for 9 of 13 patients (69.2%). At third line, 3 patients were treated by infliximab, and 1 was treated with plasma exchange. Of the 18 patients with coronary artery abnormalities at diagnosis, 13 patients at 1 month and 6 patients at 1 year had coronary artery dilatation (median z score 3.0, 2.6, and 1.4, respectively). There were no patients with coronary artery aneurysm (CAA).

CONCLUSIONS

Our strategy for refractory Kawasaki disease was safe and effective in preventing CAA.

The palliation of cerebral tumours with high-dose dexamethasone: a review

The historical use of corticosteroids for cerebral oedema due to malignancy is reviewed. The mechanisms for the formation and treatment of cerebral oedema are discussed and advice is given as to the clinical use of dexamethasone, including mention of adverse effects and drug interactions.

Complications Associated With High-dose Corticosteroid Administration in Children With Spinal Cord Injury

BACKGROUND

Complications with high-dose steroid administration for spinal cord injury are documented in adult patients. Our purpose was to determine the incidence of early complications of this therapy in pediatric patients with spinal cord injuries.

METHODS

An IRB-approved retrospective review was performed for patients treated for spinal cord injury at a level 1 pediatric trauma center between 2003 and 2011. Demographic data, injury characteristics, and surgical interventions were documented. Complications were divided into 4 categories: infectious, gastrointestinal (GI), hyperglycemia/endocrine, and wound healing problems. Complication rates were compared using a Student's t test and Fischer's exact test.

RESULTS

Thirty-four spinal cord injury patients were identified. Twenty-three patients (mean age 6.6 y) in the treatment group received high-dose steroid treatment and 11 patients (mean age 8.4 y) did not and comprised the control group. No statistical difference was detected between the 2 groups regarding age, mechanism of injury, rate of surgical intervention, level of injury, and injury severity. Hyperglycemia was the most common complication and was present in all patients in both the treatment and control groups. The overall infection rate was 64% in the control group compared with 26% in the treatment (P<0.05). The control group demonstrated a significantly increased rate of respiratory tract infections [45% control vs. 9% treatment (P<0.05)]. No surgical patients developed a wound infection. One treatment group patient experienced a GI bleed.

CONCLUSIONS

This is the largest study evaluating the complications associated with high-dose steroid administration for spinal trauma in a pediatric population. Hyperglycemia was found in all spinal cord injury patients, regardless of steroid treatment. Paradoxically, infection rates were noted to be higher in the control group. GI and wound problems were not significantly different. Larger, multicenter prospective studies are needed to better understand the risks in pediatric SCI patients.

Outpatient management of inflammatory bowel disease

Inflammatory bowel disease is a conglomeration of disorders of unclear etiology and pathogenesis. Confirming the diagnosis of active disease may be difficult but is critical to judicious therapy. Sulfasalazine (Azulfidine) and its newer derivatives mesalamine (Asacol, Rowasa) and olsalazine sodium (Dipentum) are used for treatment of mild disease and maintenance. Corticosteroid therapy controls moderate disease in most patients, but withdrawal may be difficult. Immunosuppression or surgery may be necessary in severe or refractory cases. The risk of cancer as a complication of inflammatory bowel disease is often exaggerated but cannot be ignored.

Peptic ulcer disease in endogenous hypercortisolism: myth or reality?

Many clinicians believe hypercortisolism is ulcerogenic. However, data from clinical studies show that prophylaxis for peptic ulcer disease is no longer recommended in patients receiving corticosteroid treatment. This has not yet been verified in endogenous hypercortisolism by controlled clinical studies. The purpose of the current study was to evaluate the relationship between endogenous Cushing's syndrome (CS) and peptic ulcer disease and Helicobacter pylori infection. The study group contained 20 cases with CS resulting from ACTH-dependent endogenous hypercortisolism. The control groups consisted of 14 age- and gender-matched cases receiving exogenous corticosteroid therapy and 100 cases of dyspepsia with non-cushingoid features. Upper gastrointestinal endoscopy was performed on all cases. Biopsies were taken from five different points: two samples from the antrum, two samples from the corpus, and one sample from the fundus. A histological diagnosis of Helicobacter pylori infection was also obtained from evaluation of biopsy specimens. The frequency of stomach and duodenal ulcers did not vary between the groups (p = 0.5 and p = 0.7). Antral gastritis was less frequent and pangastritis was more common in cases with CS compared to the healthy controls (p = 0.001 and p < 0.001). The incidence of Candida esophagitis was more frequent in cases with CS compared to cases with corticosteroid treatment and healthy controls (p = 0.03). Histopathological findings and frequency of Helicobacter pylori based on pathology results did not vary between the three groups. It is possible that neither exogenous nor endogenous corticosteroid excess directly causes peptic ulcer or Helicobacter pylori infection. Prophylactic use of proton pump inhibitors is not compulsory for hypercortisolism of any type.

Short-term use of glucocorticoids and risk of peptic ulcer bleeding: a nationwide population-based case-crossover study

BACKGROUND

Controversy exists regarding glucocorticoids therapy and the risk of peptic ulcer bleeding (PUB).

AIM

The present study was undertaken to determine whether short-term use of glucocorticoids is associated with the occurrence of peptic ulcer bleeding.

METHODS

The records of adult patients hospitalised for newly diagnosed peptic ulcer bleeding from 2000 to 2012 were retrieved from the Taiwan National Health Insurance Research Database, a nationwide population-based registry system. The association between systemic glucocorticoids usage and peptic ulcer bleeding was determined with a conditional logistic regression model comparing cases and controls during time windows of 7, 14 and 28 days using a case-crossover design.

RESULTS

Of the 8894 enrolled patients, the adjusted self-matched odds ratios for peptic ulcer bleeding after exposure to the glucocorticoids were 1.37 (95% CI: 1.12-1.68, P = 0.003) for the 7-day window, 1.66 (95% CI: 1.38-2.00, P < 0.001) for the 14-day window and 1.84 (95% CI: 1.57-2.16, P < 0.001) for the 28-day window. Moderate to high, but not low dose glucocorticoids (methylprednisolone <4 mg/day or its equivalence) were associated with an increased risk of peptic ulcer bleeding. Concomitant use of a nonselective nonsteroidal anti-inflammatory drug (NSAID) or aspirin further elevated the risk. However, it does not eliminate the effect of underlying diseases flare-up that may have placed the patients at risk for peptic ulcer bleeding in this kind of study design.

CONCLUSIONS

Short-term (7-28 days) exposure to glucocorticoids is significantly associated with peptic ulcer bleeding; this risk seems dose-dependent and is higher when nonselective NSAIDs or aspirin are used concurrently.

The safety of low-dose glucocorticoids in rheumatic diseases: results from observational studies

Glucocorticoids (GC) remain the most commonly used agents for managing inflammatory rheumatic diseases. The adverse effects (AEs) associated with high-dose GCs are well established, but there is a widespread misconception that AEs of high-dose GC therapy (>30 mg of prednisone or equivalent daily) are similar in low-dose therapy (≤7.5 mg of prednisone equivalent a day). Although high-quality evidence on AEs of low-dose GC therapy is still incomplete, risks and safety of low-dose GC therapy in rheumatic diseases are reviewed based on current evidence by category, including musculoskeletal, cardiovascular, infectious, gastrointestinal, neuropsychiatric, endocrine and metabolic, dermatologic, and ophthalmologic AEs. Recommendations concerning monitoring AEs with low-dose GC therapy are provided for each category of AEs on the basis of our literature review and clinical experience. There is emerging evidence that low-dose GCs are associated with a much lower level of AEs, which would allow their use over long periods in patients with rheumatic disease who gain clinical effectiveness and well-being from their use. Nonetheless, knowledge and understanding of AEs from low-dose GCs is vital to maximize benefits and minimize risks to patients.

Recommendations for bowel obstruction with peritoneal carcinomatosis

This article reports on the clinical practice guidelines developed by a multidisciplinary group working on the indications and uses of the various available treatment options for relieving intestinal obstruction or its symptoms in patients with peritoneal carcinomatosis. These guidelines are based on a literature review and expert opinion. The recommended strategy involves a clinical and radiological evaluation, of which CT of the abdomen is a crucial component. The results, together with an analysis of the prognostic criteria, are used to determine whether surgery or stenting is the best option. In most patients, however, neither option is feasible, and the main emphasis, therefore, is on the role and administration of various symptomatic medications such as glucocorticoids, antiemetic agents, analgesics, and antisecretory agents (anticholinergic drugs, somatostatin analogues, and proton-pump inhibitors). Nasogastric tube feeding is no longer used routinely and should instead be discussed on a case-by-case basis. Recent studies have confirmed the efficacy of somatostatin analogues in relieving obstruction-related symptoms such as nausea, vomiting, and pain. However, the absence of a marketing license and the high cost of these drugs limit their use as the first-line treatment, except in highly selected patients (early recurrence). When these medications fail to alleviate the symptoms of obstruction, venting gastrostomy should be considered promptly. Rehydration is needed for virtually every patient. Parenteral nutrition and pain management should be adjusted according to the patient needs and guidelines.

Corticosteroids and risk of gastrointestinal bleeding: a systematic review and meta-analysis

OBJECTIVE

To assess whether corticosteroids are associated with increased risk of gastrointestinal bleeding or perforation.

DESIGN

Systematic review and meta-analysis of randomised, double-blind, controlled trials comparing a corticosteroid to placebo for any medical condition or in healthy participants. Studies with steroids given either locally, as a single dose, or in crossover studies were excluded.

DATA SOURCES

Literature search using MEDLINE, EMBASE and Cochrane Database of Systematic Reviews between 1983 and 22 May 2013.

OUTCOME MEASURE

Outcome measures were the occurrence of gastrointestinal bleeding or perforation. Predefined subgroup analyses were carried out for disease severity, use of non-steroidal anti-inflammatory drugs (NSAIDs) or gastroprotective drugs, and history of peptic ulcer.

RESULTS

159 studies (N=33 253) were included. In total, 804 (2.4%) patients had a gastrointestinal bleeding or perforation (2.9% and 2.0% for corticosteroids and placebo). Corticosteroids increased the risk of gastrointestinal bleeding or perforation by 40% (OR 1.43, 95% CI 1.22 to 1.66). The risk was increased for hospitalised patients (OR 1.42, 95% CI 1.22 to 1.66). For patients in ambulatory care, the increased risk was not statistically significant (OR 1.63, 95% CI 0.42 to 6.34). Only 11 gastrointestinal bleeds or perforations occurred among 8651 patients in ambulatory care (0.13%). Increased risk was still present in subgroup analyses (studies with NSAID use excluded; OR 1.44, 95% CI 1.20 to 1.71, peptic ulcer as an exclusion criterion excluded; OR 1.47, 95% CI 1.21 to 1.78, and use of gastroprotective drugs excluded; OR 1.42, 95% CI 1.21 to 1.67).

CONCLUSIONS

Corticosteroid use was associated with increased risk of gastrointestinal bleeding and perforation. The increased risk was statistically significant for hospitalised patients only. For patients in ambulatory care, the total occurrence of bleeding or perforation was very low, and the increased risk was not statistically significant.

A practical guide to the monitoring and management of the complications of systemic corticosteroid therapy

Systemic corticosteroids play an integral role in the management of many inflammatory and immunologic conditions, but these agents are also associated with serious risks. Osteoporosis, adrenal suppression, hyperglycemia, dyslipidemia, cardiovascular disease, Cushing’s syndrome, psychiatric disturbances and immunosuppression are among the more serious side effects noted with systemic corticosteroid therapy, particularly when used at high doses for prolonged periods. This comprehensive article reviews these adverse events and provides practical recommendations for their prevention and management based on both current literature and the clinical experience of the authors.

Steroid ulcers: Any news?

Steroid ulcers, although a common feature in experimental studies, seldom develop in clinical practice, as observed by the meta-analyses carried out in the 90s. Corticosteroids alone become ulcerogenic only if treatment lasts longer than one month and the total administered dose exceeds 1000 mg. On the other hand concomitant intake of non-steroidal anti-inflammatory drugs results in a synergistic, highly damaging effect on the gastroduodenal mucosa. Thus, despite the survival of the steroid ulcer myth in the medical culture, pharmacological protection against steroid-induced peptic ulcers is a rare necessity while the best prophylactic strategy still remains to be determined.

Corticosteroids in brain cancer patients: benefits and pitfalls

Glucocorticoids have been used for decades in the treatment of brain tumor patients and belong to the most powerful class of agents in reducing tumor-associated edema and minimizing side effects and the risk of encephalopathy in patients undergoing radiation therapy. Unfortunately, corticosteroids are associated with numerous and well-characterized adverse effects, constituting a major challenge in patients requiring long-term application of corticosteroids. Novel antiangiogenic agents, such as bevacizumab (Avastin®), which have been increasingly used in cancer patients, are associated with significant steroid-sparing effects, allowing neuro-oncologists to reduce the overall use of corticosteroids in patients with progressive malignant brain tumors. Recent experimental studies have revealed novel insights into the mechanisms and effects of corticosteroids in cancer patients, including modulation of tumor biology, angiogenesis and steroid-associated neurotoxicity. This article summarizes current concepts of using corticosteroids in brain cancer patients and highlights potential pitfalls in their effects on both tumor and neural progenitor cells.

Another 'Cushing ulcer'

The authors describe the case of a 39-year-old man who presented to our hospital with easy fatigability and malaise. On physical examination, hypertension was noted without any cushingoid appearance. Laboratory testing revealed normochromic-normocytic anaemia with positive results of occult blood in the stool, hyperglycaemia and hypokalemia. Upper endoscopy revealed active gastric ulcer with Helicobacter pylori infection, likely causing gastrointestinal bleeding. Endocrine examinations showed that both serum adrenocorticotropic hormone and cortisol were elevated with loss of diurnal variation. A diagnosis of Cushing's disease secondary to pituitary adenoma was made as results of brain MRI and blood sampling from inferior petrosal sinus. In a patient with peptic ulcer disease, physician should be alert to the possible endocrine background.

Proton pump inhibitors and rebound acid hypersecretion

Rebound acid hypersecretion is defined as an increase in gastric acid secretion above pre-treatment levels after cessation of antisecretory therapy. Proton pump inhibitors (PPIs) have been proved to be more effective than histamine-2 receptor antagonists in suppressing intragastric acidity and have therefore become the main choice for management of acid-related complaints. Recent studies have shown that PPI therapy-elicited rebound acid hypersecretion could in turn induce acid-related symptoms. This makes it difficult for patients to cease PPI therapy. Hypergastrinemia is an important mechanism that leads to rebound acid hypersecretion. To reduce the occurrence of rebound acid hypersecretion, efforts should be made to restrict indications for using PPIs.

"A surviving myth"--corticosteroids are still considered ulcerogenic by a majority of physicians

OBJECTIVE

Evidence does not support an association between systemic corticosteroid use and the development of peptic ulcer disease (PUD) and prophylactic anti-ulcer therapy is not routinely indicated. The aim was to find out the opinion of physicians in the Czech Republic on corticosteroid-induced ulcers.

MATERIALS AND METHODS

A questionnaire-based study targeting 360 physicians of different specialties (100 from Gastroenterology, 100 from General Practice, 80 from Pneumology/Immunology, and 80 from Neurology/Neurosurgery).

RESULTS

Eighty-two percent of the physicians considered corticosteroids ulcerogenic, 7.5% of the responders considered them ulcerogenic only in patients with a family history of PUD, and 10.3% of the physicians considered corticosteroids non-ulcerogenic. Seventy-five percent of the responders would administer concomitant antisecretory treatment. Sixty-seven percent of the physicians thought that PUD was a frequent complication of corticosteroid therapy. If the ulcerogenic potential of ibuprofen, diclofenac, and prednisone was a subject of the physicians' judgment, a majority (40.5%) considered prednisone to be the most ulcerogenic substance. Thirty percent of gastroenterologists (vs. 1.9% of others; p < 0.001) did not consider corticosteroids to be ulcerogenic; 27.4% (vs. 4.3%; p < 0.01) would not administer an antisecretory prophylaxis routinely.

CONCLUSIONS

Although there is no evidence showing an association between PUD and the use of corticosteroids, a majority of physicians consider corticosteroids gastrotoxic. This applies, to a lesser extent, to gastroenterologists. Action should be taken to explode the myth about the gastrotoxicity of corticosteroids and to minimize useless expenses on concomitant prophylaxis.

Gastric mucosal injury in systemic lupus erythematosus patients receiving pulse methylprednisolone therapy

AIMS

Whether glucocorticoids induce gastric mucosal injury remains uncertain. We investigated whether very high-dose steroids caused gastric mucosal injury in systemic lupus erythematous (SLE) patients and evaluated the possible risk factors for mucosal injury.

METHODS

In this prospective paired study, 67 SLE patients who had received pulse methylprednisolone therapy were enrolled. Each patient underwent endoscopic examination and tissue and blood sampling before and after pulse steroid therapy. Mucosal injury was diagnosed if the follow-up injury scale was higher than the initial scale. Examined parameters included Helicobacter pylori infection, cyclooxygenase (COX)-1 and COX-2 activity, and current nonsteroidal anti-inflammatory drug (NSAID) usage including aspirin.

RESULTS

Eleven (16.4%) of 67 cases who developed gastric mucosal injury after pulse therapy had significantly higher rates of peptic ulcer history, NSAID/aspirin use, lower gastric thromboxane B(2) and prostaglandin E(2) levels when compared with cases without gastric mucosal injury (P < 0.05). Infection by H. pylori was not a risk factor for gastric mucosal injury. Multivariate logistic regression analysis showed that NSAID/aspirin use was the only risk factor for gastric mucosal injury in these patients (odds ratio 26.99, 95% confidence interval 4.91, 148.57, P < 0.0001). Pulse steroid therapy alone did not induce gastric mucosal injury in fifty SLE patients without taking any NSAID/aspirin.

CONCLUSIONS

Use of NSAIDs/aspirin, but not H. pylori infection, increases gastric mucosal injury in SLE patients receiving pulse methylprednisolone therapy. Very high-dose steroids de novo seem not to induce gastric mucosal injury in these patients. A larger case-controlled study enrolling a heterogeneous population is needed to clarify the role of glucocorticoids in gastric mucosal injury.

Risk factors for the development of gastric mucosal lesions in rheumatoid arthritis patients receiving long-term nonsteroidal anti-inflammatory drug therapy and the efficacy of famotidine obtained from the FORCE study

The objective of this study was to investigate the prevalence of gastric mucosal injury induced by nonsteroidal anti-inflammatory drugs (NSAIDs) in patients with rheumatoid arthritis (RA). Upper gastrointestinal endoscopy was performed on 100 RA patients treated with NSAIDs. Patient factors potentially contributing to the development of NSAID-induced gastric mucosal injury were identified by logistic regression analysis; gastric mucosal injury and ulcers were used as objective variables. Gastric mucosal injury was detected in 62 of 100 patients, and eight of these patients had ulcers. Previous history of ulcers, lifestyle, NSAID dosage, and body mass index were associated with the development of gastric mucosal injury,and the use of diclofenac and steroid dose were associated with the development of ulcers. Disease-modifying antirheumatic drugs (DMARDs) did not appear to influence the risk of NSAID-induced gastric mucosal injury. RA patients treated for long periods with NSAIDs for RA symptoms should be controlled with DMARDs, without consideration of increased doses of steroids, in terms of risk for NSAID-induced gastric mucosal injury. Simultaneously, concomitant use of histamine-2 receptor antagonists (H2RA) such as famotidine should be considered.

Stress-related mucosal bleeding in critically ill oncology patients

Objective. To determine the incidence of stress-related mucosal bleeding (SRMB) in a critically ill oncology population receiving stress ulcer prophylaxis (SUP) with either a histamine-2 receptor antagonist (H2RA) or proton pump inhibitor (PPI). Design. Single-center, prospective, observational study.

Setting. Fifty-two bed medical-surgical intensive care unit of an academic oncology institution. Patients. A convenience sample of 100 medical and surgical critically ill oncology patients who received intensive care for more than 24 hours and at least one dose of a H2RA or PPI for prevention of SRMB.

Interventions. None.

Measurements and Main Results. Patients were followed throughout their intensive care unit stay for the development of an overt and/or clinically significant gastrointestinal (GI) bleed. More patients received a PPI (n = 81) in contrast to a H2RA (n = 19) for SUP. Overall, 94 patients (94%) had at least one risk factor for a SRMB with four patients (4%) experiencing an event (overt bleed, n=3; clinically significant bleed, n =1). All cases of GI bleeding occurred in patients receiving a PPI. No ICU deaths were considered directly related to a GI bleed.

Conclusions. The incidence of SRMB among high-risk critically ill oncology patients receiving SUP appears low; further, large-scale trials are needed to confirm this finding. J Oncol Pharm Practice (2009) 15: 9—16.

Prevalence of gastrointestinal symptoms in patients with chronic obstructive pulmonary disease

BACKGROUND

Symptoms of gastro-oesophageal reflux disease (GERD) have previously been shown to be of importance in patients with asthma. Limited data, however, exist on the prevalence of GERD in patients with chronic obstructive pulmonary disease (COPD), and information about the occurrence of the total burden of gastrointestinal (GI) symptoms in these patients is lacking.

METHODS

A total of 113 patients with COPD completed four self-administered questionnaires: the Gastrointestinal Symptom-Rating Scale (GSRS), ROME II modular questionnaires (criteria for irritable bowel syndrome), the Psychological General Well-Being index (PGWB), and the Hospital Anxiety and Depression scale. Eighty-two patients with chronic renal failure (CRF) and 2000 healthy individuals from the general Swedish population served as controls.

RESULTS

The total GSRS score in patients with COPD was 2.12 (1.92-2.28) which was significantly higher than the score from the general population of 1.96 (1.81-2.12). No significant difference between COPD and CRF patients was, however, observed, in any of the GSRS dimensions. Patients in the COPD group had lower total PGWB scores compared both with CRF patients 90 (78-104) vs. 98 (83-113) (P<0.05) and with the general population 103 (102-104) (P<0.001). A negative correlation between the GSRS and PGWB scores (r=-0.49; P<0.001) was observed in patients with COPD. Sixteen (14%) of the patients with COPD fulfilled the Rome II criteria for irritable bowel syndrome.

CONCLUSION

The prevalence of GI symptoms is higher in patients with COPD than in healthy individuals, but not higher than in CRF patients. The GI symptoms are associated with impairments in psychological well-being, and they require diagnostic workups to explore different treatment options in these patients.

Meta-analysis of randomized controlled trials as a method of estimating rare complications of non-steroidal anti-inflammatory drug therapy

The design of randomized controlled trials to assess the efficacy of pharmacological measures for the prevention of the gastrointestinal side-effects of anti-inflammatory drugs requires an accurate estimate of excess risk under controlled conditions. Photocopies of 952 randomized controlled trial publications were obtained after scanning titles and abstracts of a MEDLINE computer search, 427 were excluded for obvious reasons, and 525 were again photocopied after obliterating source and results. Selection criteria were: the presence of a non-anti-inflammatory drug control group; at least 4 days of therapy; at least 3 days without anti-inflammatory drugs before randomization; no complicating background drugs; mention of side-effects; and a clear differentiation of gastrointestinal complications. Observer error, with two independent readings, for inclusion suitability in the study was 19% for Methods and 9% for Results. For the 44 aspirin trials, the mean therapy duration was 357 days; the unweighted rate difference between therapy and control groups ( +/- 1 S.E.M.) for ulcer was 0.006 +/- 0.003, for gross haemorrhage 0.006 +/- 0.002 and for unspecified gastric symptoms 0.03 +/- 0.01. In 123 non-aspirin non-steroidal anti-inflammatory drug (NA-NSAID) trials, the mean duration was 67 days; the unweighted rate difference for ulcer was 0.0005 +/- 0.0003, for gross haemorrhage 0.007 +/- 0.004 and for unspecified gastric symptoms 0.02 +/- 0.005. Risk differences were also pooled using the DerSimonian and Laird method, which weights studies inversely according to variance. Using this method, only the unspecified gastric symptoms for non-aspirin non-steroidal anti-inflammatory drugs (NA-NSAIDs) and the haemorrhage for aspirin were found to be statistically significant. Longer studies have higher risk differences. Randomized control trials to determine prophylactic efficacy against haemorrhage (that is, to demonstrate a reduction of ulcer rate in the therapy group to the rate of controls) would require 190 patients in each group for NA-NSAIDs in studies of 2-6 months; 950 subjects would be needed to detect a 50% reduction. Randomized control trials to determine a reduction in ulcer rate to that of controls in patients on aspirin for more than 6 months would require 700 subjects in each group; 3346 subjects would be needed to detect a 50% reduction. Such studies are feasible.

Supportive Care of Brain Tumor Patients

The supportive care of patients who have brain tumors consists mainly of the treatment of brain edema, seizures, venous thromboembolism, and cognitive dysfunction. Each of these complications may occur in patients who have primary or metastatic brain tumors. The development of any of these complications significantly increases the morbidity and mortality associated with brain tumors. Effective treatment is usually possible, however, and can result in an improved quality of life for these patients.

Medical management of patients with brain tumors

The most common medical problems in brain tumor patients include the management of seizures, peritumoral edema, medication side effects, venous thromboembolism (VTE), fatigue and cognitive dysfunction. Despite their importance, there are relatively few studies specifically addressing these issues. There is increasing evidence that brain tumor patients who have not had a seizure do not benefit from prophylactic antiepileptic medications. Patients on corticosteroids are at greater risk of Pneumocystis jerovecii pneumonia and may benefit from prophylactic therapy. There is also growing evidence suggesting that anticoagulation may be more effective than inferior vena cava IVC) filtration devices for treating VTE in brain tumor patients and the risk of hemorrhage with anticoagulation is relatively small. Low-molecular weight heparin may be more effective than coumadin. Medications such as modafinil and methylphenidate have assumed an increasing role in the treatment of fatigue, while donepezil and memantine may be helpful with memory loss.

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.

Perforated peptic ulcer: use of pre-admission oral glucocorticoids and 30-day mortality

BACKGROUND

Despite evidence that use of glucocorticoids increases the risk of complicated peptic ulcer disease, limited data exist on how use of oral glucocorticoids affects outcome for patients with peptic ulcer perforation.

AIM

To examine 30-day mortality from peptic ulcer perforation among pre-admission oral glucocorticoid users compared with non-users.

METHODS

We identified 2061 patients with a first-time hospital discharge diagnosis of perforated peptic ulcer, using population-based discharge registries in three Danish counties. Data on use of glucocorticoids and other ulcer-related drugs, previous hospitalizations for uncomplicated peptic ulcer disease, and comorbidity were obtained from discharge registries and prescription databases. Follow-up data on mortality were provided by the Danish Civil Registry System.

RESULTS

A total of 228 patients (11.1%) were exposed to glucocorticoids within 60 days of admission. Overall 30-day mortality rate was 25.2%, the corresponding rate among current glucocorticoid users was 39.4%. Compared with 'never users', the adjusted mortality ratio among current users of oral glucocorticoids alone was 2.1 (95% CI: 1.5-3.1). Among current users of oral glucocorticoids in combination with other ulcer-related drugs the mortality ratio was 1.5 (95% CI: 1.1-2.1).

CONCLUSION

Pre-admission use of oral glucocorticoids is associated with up to a twofold increase in 30-day mortality among patients hospitalized with perforated peptic ulcer.

Risk of serious upper gastrointestinal toxicity with over-the-counter nonaspirin nonsteroidal anti-inflammatory drugs

BACKGROUND & AIMS

Use of prescription nonaspirin nonsteroidal anti-inflammatory drugs (NANSAIDs) increases the risk of serious upper gastrointestinal toxicity. Less is known about over-the-counter (OTC) NANSAIDs, which are typically used at lower doses and for shorter durations. This study assessed the risk of toxicity with OTC NANSAIDs.

METHODS

A total of 359 case subjects hospitalized for upper gastrointestinal bleeding, perforation, or benign gastric outlet obstruction were recruited from 28 hospitals. A total of 1889 control subjects were recruited by random digit dialing from the same region. Data on medication use were collected via structured telephone interview.

RESULTS

Use of OTC NANSAIDs on > or = 4 days during the most recent week had an adjusted odds ratio (OR) of 1.83 (95% confidence interval [CI], 1.14-2.95). Use of high-dose OTC NANSAIDs during the index week had an adjusted OR of 5.21 (95% CI, 2.32-11.69). In contrast, use of OTC NANSAIDs <4 times during the index week (adjusted OR, 0.67; 95% CI, 0.43-1.06) and use of very low doses of prescription or OTC NANSAIDs during the index week (adjusted OR, 0.74; 95% CI, 0.49-1.12) were not significantly associated with an increased risk of serious gastrointestinal toxicity. We did not observe a significant difference between the risk of toxicity with OTC naproxen versus OTC ibuprofen (adjusted OR, 0.84; 95% CI, 0.26-2.70).

CONCLUSIONS

Use of OTC NANSAIDs at recommended doses has a relatively good safety profile compared with prescription NANSAIDs. However, use of high-dose OTC NANSAIDs (comparable to a prescription dose) is associated with serious gastrointestinal toxicity.

Inadequate use of acid-suppressive therapy in hospitalized patients and its implications for general practice

Acid-suppressive therapy (AST) is largely prescribed in both hospital and general practice setting but few data are available on appropriateness of AST use in hospitalized patients and its fallout on prescribing in general practice. We assessed AST in patients consecutively admitted to an internal medicine department to determine the type and timing of prescription and indication for use according to widely accepted guidelines. Prescriptions were rated as indicated, acceptable, or not indicated. Overall, 58.7% of 834 admitted patients received AST, mainly proton pump inhibitors. The prescriptions were indicated in 50.1% of patients, not indicated in 41.5%, and acceptable in 6.5%. The main reason for inappropriate use was prophylaxis in low-risk patients (64.8%). On admission, 35.7% of 112 patients already on AST were judged to receive inappropriate prescription; of 348 patients discharged on AST, overuse was identified in 38.5%. No significant difference was observed for inappropriate use at admission, during hospitalization, and at discharge. In 64 inpatients (7.7%) AST, although indicated, mainly for ulcer prophylaxis in high-risk patients, was not prescribed. In conclusion, AST is substantially over-used in both hospital and general practice settings, mainly for ulcer prophylaxis in low-risk patients. On the other hand, AST is underused in a small, but not negligible proportion of high-risk patients.

Current use of glucocorticoids in patients with rheumatoid arthritis in Germany

OBJECTIVE

To describe the current use of glucocorticoids in German patients with rheumatoid arthritis (RA).

METHODS

We analyzed clinical and patient-derived data from 10,068 outpatients with RA from the national database of the German Collaborative Arthritis Centres for the year 2001 collected by more than 80 rheumatologists in hospitals and private practices.

RESULTS

Systemic glucocorticoid therapy was prescribed for 60% of all patients with RA in rheumatologic care. The proportion of patients receiving systemic glucocorticoids in addition to disease-modifying antirheumatic drug (DMARD) therapy ranged from 53% to 81% of the patients for the various DMARDs. Glucocorticoid therapy was administered more often in combination with tumor necrosis factor inhibitors (81%), cyclosporin A (80%), or leflunomide (77%) than with more traditional DMARDs such as methotrexate (63%) or sulfasalazine (55%). Regarding the prevention and treatment of osteoporosis, 63% of patients taking systemic glucocorticoids were also receiving some type of osteoporosis therapy, as opposed to only 26% of those not taking glucocorticoids.

CONCLUSION

Glucocorticoids play a pivotal role in the management of RA. This is reflected in the extensive use of low-dose glucocorticoids by German rheumatologists. Even if highly effective DMARDs are prescribed, they are accompanied by glucocorticoids, at least in the initial phase. High-dose glucocorticoids are prescribed for only a small proportion of the patients. There is increasing awareness of the risk of osteoporosis in long-term glucocorticoid treatment, demonstrated by the fact that osteoporosis medication is prescribed for a large proportion of patients taking glucocorticoids.

Corticosteroid use in the treatment of neuromuscular disorders: empirical and evidence-based data

Corticosteroids have been used to treat neuromuscular disorders for many years. With few randomized, controlled trials, efficacy has been established primarily from empirical data. This has led to a range of treatment regimens varying in terms of initial dosing, dosing schedules, and taper rates. The goals of this review were to examine the literature for data concerning corticosteroid pharmacokinetics and for evidence-based treatment regimens in several prototypic neuromuscular disorders. The results provide a number of sound principles for corticosteroid use, but also indicate that corticosteroid regimens and patient management are largely based on empirical clinical experiences.

NSAIDs: gastroprotection or selective COX-2 inhibitor?

Conventional nonsteroidal anti-inflammatory drugs (NSAIDs) are effective adjuvant analgesics commonly encountered in palliative care. However, these drugs are associated with adverse effects that are primarily due to gastrointestinal toxicity, with resultant serious complications such as gastroduodenal perforations, ulcers and bleeds. This toxicity has been attributed to inhibition of cyclooxygenase-1 (COX-1). Factors known to increase this risk of toxicity include age above 65 years, classification of NSAID in terms of COX-1/COX-2 selectivity, previous history of complications and coadministration of aspirin, anticoagulants and corticosteroids. Selective inhibitors of cyclooxygenase-2 (COX-2) were developed in an attempt to reduce this association; trials to date confirm that these drugs do indeed have reduced incidence of gastroduodenal toxicity. Prior to the introduction of the COX-2 selective inhibitors, patients at high risk were often coprescribed a gastroprotective agent (such as misoprostol or a proton pump inhibitor) with a conventional NSAID. This review discusses the merits of both options and devises a treatment strategy for the safe and cost-effective use of these drugs in the palliative care population.

The role of systemic corticosteroids in acute exacerbation of chronic obstructive pulmonary disease

The administration of systemic corticosteroids for patients with exacerbations of chronic obstructive pulmonary disease (COPD) has become common practice over the past 25 years. This practice remained somewhat controversial because corticosteroids can have serious adverse effects and initial clinical trials provided inconclusive evidence concerning their efficacy. Results from recent clinical trials indicate that systemic corticosteroids are modestly effective in shortening the duration of severe exacerbations of COPD. Systemic corticosteroids administered intravenously or orally to hospitalized patients with exacerbations of COPD reduced the absolute treatment failure rate by about 10%, increased the forced expiratory volume in 1 second (FEV1) by about 100 ml, and shortened the hospital stay by 1 to 2 days. Oral corticosteroids probably confer similar benefits when used for treating moderately severe COPD exacerbations in an out-patient setting. The optimal starting dose of corticosteroids is not known, but the duration of treatment should not extend longer than 2 weeks. Hyperglycemia is the most common adverse event, but secondary infections, mental disturbances, and myopathies may also occur.
