Continuous infusion versus bolus administration of steroids in severe attacks of ulcerative colitis: a randomized, double-blind trial

GADECCU 2022 Guideline for the treatment of Ulcerative Colitis. Adaptation and updating of the GETECCU 2020 Guideline

INTRODUCTION

Ulcerative colitis (UC) is a chronic inflammatory disease that compromises the colon, affecting the quality of life of individuals of any age. In practice, there is a wide spectrum of clinical situations. The advances made in the physio pathogenesis of UC have allowed the development of new, more effective and safer therapeutic agents.

OBJECTIVES

To update and expand the evaluation of the efficacy and safety of relevant treatments for remission induction and maintenance after a mild, moderate or severe flare of UC.

RECIPIENTS

Gastroenterologists, coloproctologists, general practitioners, family physicians and others health professionals, interested in the treatment of UC.

METHODOLOGY

GADECCU authorities obtained authorization from GETECCU to adapt and update the GETECCU 2020 Guide for the treatment of UC. Prepared with GRADE methodology. A team was formed that included authors, a panel of experts, a nurse and a patient, methodological experts, and external reviewers. GRADE methodology was used with the new information.

RESULTS

A 118-page document was prepared with the 44 GADECCU 2022 recommendations, for different clinical situations and therapeutic options, according to levels of evidence. A section was added with the new molecules that are about to be available.

CONCLUSIONS

This guideline has been made in order to facilitate decision-making regarding the treatment of UC, adapting and updating the guide prepared by GETECCU in the year 2020.

Korean clinical practice guidelines on biologics and small molecules for moderate-to-severe ulcerative colitis

Ulcerative colitis (UC), a relapsing-remitting chronic inflammatory bowel disease (IBD), has a variable natural course but potentially severe disease course. Since the development of anti-tumor necrosis factor (TNF) agents has changed the natural disease course of moderate-to-severe UC, therapeutic options for patients who failed conventional treatments are expanding rapidly. IBD clinical trials have demonstrated the potential efficacy and safety of novel biologics such as anti-integrin α4β7 and anti-interleukin-12/23 monoclonal antibodies and small molecules such as a Janus kinase inhibitor. Anti-TNF biosimilars also have been approved and are widely used in IBD patients. Wise drug choices should be made considering evidence-based efficacy and safety. However, the best position of these drugs remains several questions, with limited data from direct comparative trials. In addition, there are still concerns to be elucidated on the effect of therapeutic drug monitoring and combination therapy with immunomodulators. The appropriate treatment regimens in acute severe UC and the risk of perioperative use of biologics are unclear. As novel biologics and small molecules have been approved in Korea, we present the Korean guidelines for medical management of adult outpatients with moderate-to-severe UC and adult hospitalized patients with acute severe UC, focusing on biologics and small molecules.

A comparison of intravenous methylprednisolone and hydrocortisone for the treatment of acute inflammatory bowel disease

BACKGROUND AND AIM

Despite widespread recommendations and use of intravenous corticosteroids (IVCS) for the treatment of acute flares of ulcerative colitis and Crohn's disease, limited evidence exists comparing outcomes of the two most common regimens, intravenous methylprednisolone (IVMP) and intravenous hydrocortisone (IVHC). IVHC has stronger mineralocorticoid effects compared with IVMP and may cause higher rates of hypokalemia. We aimed to determine differences in clinical outcomes including requirement for inpatient rescue therapy, bowel resection, and rates of hypokalemia.

METHODS

We conducted a multicenter cohort study of all adult patients admitted with an acute flare of inflammatory bowel disease (IBD) to the three tertiary hospitals in Auckland, New Zealand, where the protocol at each institution is either IVMP 60 mg daily or IVHC 100 mg four times daily. All patients requiring IVCS between 20 June 2016 and 30 June 2018 were included. The IVCS protocol was then changed at one hospital, where further data were collected for a further 12 months from 30 January 2019 until 30 December 2019.

RESULTS

There were 359 patients, including 129 (35.9%) patients receiving IVMP and 230 (64.1%) patients receiving IVHC. IVMP treatment was associated with a greater requirement for rescue therapy than IVHC (36.4% vs 19.6%, P = 0.001; odds ratio [OR] = 2.79; 95% confidence interval [CI], 1.64-4.75, P < 0.001), but also reduced rates of hypokalemia (55.8% vs 67.0%, P = 0.04; OR = 0.49; 95% CI, 0.30-0.81, P = 0.005). There was no difference between treatment groups for the median length of admission (5 days, interquartile range [IQR] 3-8), median duration of IVCS treatment (3 days, IQR 2-5), or bowel resection within 30 days of admission (12.4% vs 11.7%; OR = 1.04).

CONCLUSION

For the treatment of an acute flare of IBD, treatment with IVMP results in significantly more requirement for inpatient rescue biologic or cyclosporin. In addition, it causes statistically significant less hypokalemia than IVHC, although in practice differences are negligible.

Acute severe ulcerative colitis: management advice for internal medicine and emergency physicians

Acute severe ulcerative colitis is a medical emergency that warrants in-patient management. This is best served within a multidisciplinary team setting in specialised centres or with expert consultation. Intravenous corticosteroids remain the cornerstone in the management of ASUC and should be initiated promptly, along with general management measures and close monitoring of patients. Unfortunately, one-third of patients will fail to respond to steroids. Response to intravenous corticosteroid therapy needs to be assessed on the third day and rescue therapies, including cyclosporine and infliximab, should be offered to patients not responding. Choice of rescue therapy depends on experience, drug availability and factors associated with each individual patient, such as comorbidities, previous medications or contra-indications to therapy. Patients who have not responded within 7 days to rescue therapy must be considered for surgery. Surgery is a treatment option in ASUC and should not be delayed in cases of failure of medical therapy, because such delays increase surgical morbidity and mortality. This review summarises the current management of acute severe ulcerative colitis and discusses potential future developments.

GETECCU 2020 guidelines for the treatment of ulcerative colitis. Developed using the GRADE approach

INTRODUCTION

Since the first edition of the Guidelines was published in 2013, much information has been generated around the treatment of ulcerative colitis, and new drugs and action protocols have been introduced. Clinical practice has changed substantially, warranting new approaches and a comprehensive review and update of the evidence.

MATERIAL AND METHODS

Once again, we used the GRADE approach, supported by an electronic tool (https://gradepro.org). The clinical scenarios are the same as in the previous version (induction and maintenance in severe and mild-moderate flare-ups), as are the variables and their evaluation. However, in the updated guidelines, three questions have been deleted, 14 added and 30 maintained, making a total of 44 clinical questions. After an exhaustive review of the evidence, the recommendations are now updated.

RESULTS

Of the 44 questions analysed, no recommendation could be established in two due to the very low quality of the evidence, while in the other 42, based on different degrees of quality of evidence, recommendations were made according to the GRADE system. In 25 of these questions the final recommendation is strongly in favour, in six strongly against, in seven weakly in favour and in four weakly against. According to the scenarios and recommendations, six algorithms are proposed as a simple guide for practical decision-making.

CONCLUSIONS

The aim of this update of the 2013 guidelines is to provide answers, based on the GRADE approach, to the different questions we ask ourselves daily when deciding the most appropriate treatment for our patients with ulcerative colitis in the different clinical scenarios.

Optimal Management of Acute Severe Ulcerative Colitis (ASUC): Challenges and Solutions

Acute severe colitis is a severe complication of ulcerative colitis, affecting approximately 20% of patients. For physicians, it remains a challenging condition to treat. Current treatment algorithms have diminished the mortality associated with acute severe ulcerative colitis (ASUC), but colectomy rates remain high (approximately 30%) despite advances in therapy. Colectomy in ASUC is particularly associated with important postoperative complications and morbidity. In this review, reasons for the inability to improve care and avoid evolution to colectomy for ASUC are explored and solutions that might lead to a better management of the disease are investigated.

Treatment of Ulcerative Colitis with Steroids (in Whom, How Long, What Dose, What Form)

Corticosteroids are a nonspecific immune modulator used in the treatment of ulcerative colitis. Topical and systemic forms of corticosteroids have been shown to be effective in induction of clinical remission and remain first-line therapy for acute severe ulcerative colitis. A large proportion of patients experience adverse effects, however, including some serious adverse effects, including infection and increased mortality. Newer formulations of gut selective corticosteroids have reduced adverse effects associated with steroids.

The management of the hospitalized ulcerative colitis patient: the medical-surgical conundrum

PURPOSE OF REVIEW

In this review article, we address emerging evidence for the medical and surgical treatment of the hospitalized patient with ulcerative colitis.

RECENT FINDINGS

Ulcerative colitis is a chronic inflammatory disease involving the colon and rectum. About one-fifth of patients will be hospitalized from ulcerative colitis, and about 20-30%, experiencing an acute flare will undergo colectomy. Because of the significant clinical consequences, patients hospitalized need prompt evaluation for potential complications, stratification of disease severity, and a multidisciplinary team approach to therapy, which involves both the gastroenterologist and surgeon. Although corticosteroids remain first-line therapy, second-line medical rescue options, primarily infliximab or cyclosporine, are considered within 3-5 days of presentation. In conjunction, an early surgical consultation to present the possibility of a staged proctocolectomy as one of the therapeutic options is equally important.

SUMMARY

A coordinated multidisciplinary, individualized approach to treatment, involving the patient preferences throughout the process, is optimal in providing patient-centered effective care.

Inpatient Management of Inflammatory Bowel Disease-Related Complications

Despite advances in therapeutic options, a sizeable proportion of patients with inflammatory bowel disease require hospitalization or surgery during their lifetime. While current treatment guidelines for the management of ulcerative colitis and Crohn's disease cover the spectrum of disease severity and behavior, management of acute complications of inflammatory bowel disease can present unique challenges that are not always addressed in these guidelines. In this review, the authors provide a comprehensive summary of the existing literature focused on management of patients hospitalized with complications of inflammatory bowel disease. Proposed management algorithms are provided to guide clinicians through common scenarios to determine the most appropriate interventions - escalation of medical therapies, non-surgical therapeutic interventions (drainage of intra-abdominal abscess or endoscopic balloon dilation) or surgery. Prevention of complications is proposed through a multi-disciplinary approach that involves surgeons, dieticians, radiologists, pathologists and infectious disease consultants.

AGA Technical Review on the Management of Moderate to Severe Ulcerative Colitis

A subset of patients with ulcerative colitis (UC) present with, or progress to, moderate to severe disease activity. These patients are at high risk for colectomy, hospitalization, corticosteroid dependence, and serious infections. The risk of life-threatening complications and emergency colectomy is particularly high among those patients hospitalized with acute severe ulcerative colitis. Optimal management of outpatients or inpatients with moderate to severe UC often requires the use of immunomodulator and/or biologic therapies, including thiopurines, methotrexate, cyclosporine, tacrolimus, TNF-α antagonists, vedolizumab, tofacitnib, or ustekinumab, either as monotherapy or in combination (with immunomodulators), to mitigate these risks. Decisions about optimal drug therapy in moderate to severe UC are complex, with limited guidance on comparative efficacy and safety of different treatments, leading to considerable practice variability. Therefore, the American Gastroenterological Association prioritized development of clinical guidelines on this topic. To inform the clinical guidelines, this technical review was completed in accordance with the Grading of Recommendations Assessment, Development and Evaluation framework. Focused questions in adult outpatients with moderate to severe UC included: (1) overall and comparative efficacy of different medications for induction and maintenance of remission in patients with or without prior exposure to TNF-α antagonists, (2) comparative efficacy and safety of biologic monotherapy vs combination therapy with immunomodulators, (3) comparative efficacy of top-down (upfront use of biologics and/or immunomodulator therapy) vs step-up therapy (acceleration to biologic and/or immunomodulator therapy only after failure of 5-aminosalicylates, and (4) role of continuing vs stopping 5-aminosalicylates in patients being treated with immunomodulator and/or biologic therapy for moderate to severe UC. Focused questions in adults hospitalized with acute severe ulcerative colitis included: (5) overall and comparative efficacy of pharmacologic interventions for inpatients refractory to corticosteroids, in reducing risk of colectomy, (6) optimal dosing regimens for intravenous corticosteroids and infliximab in these patients, and (7) role of adjunctive antibiotics in the absence of confirmed infections.

Systematic review with meta-analysis: mortality in acute severe ulcerative colitis

BACKGROUND

Acute severe ulcerative colitis (ASUC) is a life-threatening condition. Mortality in ASUC decreased in published series but there is uncertainty as to whether this also applies to the real-life setting.

AIM

To perform a systematic review and meta-analysis of mortality in ASUC in studies from referral centres and in population-based studies, separately and combined. A second aim was to identify risk factors of mortality in ASUC.

METHODS

We searched pubmed and embase from 1998 to 2016, to identify studies that reported 3-month or 12-month mortalities of acute UC in adult patients treated in referral centres, and in population-based studies.

RESULTS

Six population-based studies with 741 743 patients and 47 referral centre-based studies with 2556 patients were included. The pooled 3-month and 12-month mortalities were respectively 0.84% and 1.01%. Advanced age was significantly associated with both 3 month and 12 month mortalities (OR = 1.15 per year, 95% CI: 1.10-1.20 and OR = 1.19 per year, 95% CI: 1.15-1.23 respectively). The pooled 3-month and 12-month mortalities were 0.78% and 0.85% in studies with median age of less than 50 and 2.81% and 4.17% in studies with median age of 50 or more, respectively. After adjustment for age, 3-month and 12-month mortalities did not differ between population-based and referral centre-based studies.

CONCLUSIONS

Mortality in acute severe ulcerative colitis is approximately 1%; it is higher in older patients. Efforts should be made to improve the care of elderly patients with severe UC.

British Society of Gastroenterology consensus guidelines on the management of inflammatory bowel disease in adults

Ulcerative colitis and Crohn's disease are the principal forms of inflammatory bowel disease. Both represent chronic inflammation of the gastrointestinal tract, which displays heterogeneity in inflammatory and symptomatic burden between patients and within individuals over time. Optimal management relies on understanding and tailoring evidence-based interventions by clinicians in partnership with patients. This guideline for management of inflammatory bowel disease in adults over 16 years of age was developed by Stakeholders representing UK physicians (British Society of Gastroenterology), surgeons (Association of Coloproctology of Great Britain and Ireland), specialist nurses (Royal College of Nursing), paediatricians (British Society of Paediatric Gastroenterology, Hepatology and Nutrition), dietitians (British Dietetic Association), radiologists (British Society of Gastrointestinal and Abdominal Radiology), general practitioners (Primary Care Society for Gastroenterology) and patients (Crohn's and Colitis UK). A systematic review of 88 247 publications and a Delphi consensus process involving 81 multidisciplinary clinicians and patients was undertaken to develop 168 evidence- and expert opinion-based recommendations for pharmacological, non-pharmacological and surgical interventions, as well as optimal service delivery in the management of both ulcerative colitis and Crohn's disease. Comprehensive up-to-date guidance is provided regarding indications for, initiation and monitoring of immunosuppressive therapies, nutrition interventions, pre-, peri- and postoperative management, as well as structure and function of the multidisciplinary team and integration between primary and secondary care. Twenty research priorities to inform future clinical management are presented, alongside objective measurement of priority importance, determined by 2379 electronic survey responses from individuals living with ulcerative colitis and Crohn's disease, including patients, their families and friends.

A current overview of corticosteroid use in active ulcerative colitis

Ulcerative colitis (UC) is a chronic inflammatory condition that causes continuous mucosal inflammation of the colon. New biological drugs have been developed in order to avoid colectomy, but corticosteroids still play a crucial role in management of active UC. Areas covered: We reviewed the current literature about the importance of corticosteroid use in the treatment of ulcerative colitis. The evidence reviewed in this article is a summation of relevant scientific publications, expert opinion statements, and current practice guidelines. This review is a summary of expert opinion in the field without a formal systematic review of evidence. Expert opinion: Corticosteroids represent the mainstay of treatment in patients with severe UC and are very effective in inducing remission in mild to moderate flares not responding to combined oral and topical mesalazine. A valid alternative to systemic corticosteroids is represented by poorly absorbed steroids, such as Beclomethasone dipropionate and Budesonide MMX. In mild-moderate distal disease topical administration of corticosteroids (both systemic and BDP) is an effective alternative to topical mesalazine. However, corticosteroids do not represent a therapeutic option as a maintenance treatment since they are associated with multiple adverse effects.

ACG Clinical Guideline: Ulcerative Colitis in Adults

Ulcerative colitis (UC) is an idiopathic inflammatory disorder. These guidelines indicate the preferred approach to the management of adults with UC and represent the official practice recommendations of the American College of Gastroenterology. The scientific evidence for these guidelines was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) process. In instances where the evidence was not appropriate for GRADE, but there was consensus of significant clinical merit, "key concept" statements were developed using expert consensus. These guidelines are meant to be broadly applicable and should be viewed as the preferred, but not only, approach to clinical scenarios.

Management of Paediatric Ulcerative Colitis, Part 2: Acute Severe Colitis-An Evidence-based Consensus Guideline From the European Crohn's and Colitis Organization and the European Society of Paediatric Gastroenterology, Hepatology and Nutrition

BACKGROUND AND AIM

Acute severe colitis (ASC) is one of the few emergencies in pediatric gastroenterology. Tight monitoring and timely medical and surgical interventions may improve outcomes and minimize morbidity and mortality. We aimed to standardize daily treatment of ASC in children through detailed recommendations and practice points which are based on a systematic review of the literature and consensus of experts.

METHODS

These guidelines are a joint effort of the European Crohn's and Colitis Organization (ECCO) and the European Society of Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN). Fifteen predefined questions were addressed by working subgroups. An iterative consensus process, including 2 face-to-face meetings, was followed by voting of the national representatives of ECCO and all members of the Paediatric Inflammatory Bowel Disease (IBD) Porto group of ESPGHAN (43 voting experts).

RESULTS

A total of 24 recommendations and 43 practice points were endorsed with a consensus rate of at least 91% regarding diagnosis, monitoring, and management of ASC in children. A summary flowchart is presented based on daily scoring of the Paediatric Ulcerative Colitis Activity Index. Several topics have been altered since the previous 2011 guidelines and from those published in adults.

DISCUSSION

These guidelines standardize the management of ASC in children in an attempt to optimize outcomes of this intensive clinical scenario.

[Acute severe colitis]

Acute severe colitis is a potentially life-threatening medical and surgical emergency requiring hospitalization and intensive monitoring. The diagnosis of severe acute colitis is based on clinical and biological criteria. Colectomy should be discussed at each stage of management and is indicated immediately in case of complications. Thromboembolic prevention with low molecular weight heparin is essential in any patient with severe acute colitis. The first-line medical treatment is intravenous corticosteroid at a dose of 0.8mg/kg/day of prednisone equivalent. In case of failure, a second line of medical treatment can be attempted in the absence of complications. The two possible treatments are infliximab and ciclosporin.

Use of corticosteroids and immunosuppressive drugs in inflammatory bowel disease: Clinical practice guidelines of the Italian Group for the Study of Inflammatory Bowel Disease

The two main forms of intestinal bowel disease, namely ulcerative colitis and Crohn's disease, are not curable but can be controlled by various medical therapies. The Italian Group for the Study of Inflammatory Bowel Disease (IG-IBD) has prepared clinical practice guidelines to help physicians prescribe corticosteroids and immunosuppressive drugs for these patients. The guidelines consider therapies that induce remission in patients with active disease as well as treatment regimens that maintain remission. These guidelines complement already existing guidelines from IG-IBD on the use of biological drugs in patients with inflammatory bowel diseases.

Safety of treatments for inflammatory bowel disease: Clinical practice guidelines of the Italian Group for the Study of Inflammatory Bowel Disease (IG-IBD)

Inflammatory bowel diseases are chronic conditions of unknown etiology, showing a growing incidence and prevalence in several countries, including Italy. Although the etiology of Crohn's disease and ulcerative colitis is unknown, due to the current knowledge regarding their pathogenesis, effective treatment strategies have been developed. Several guidelines are available regarding the efficacy and safety of available drug treatments for inflammatory bowel diseases. Nevertheless, national guidelines provide additional information adapted to local feasibility, costs and legal issues related to the use of the same drugs. These observations prompted the Italian Group for the Study of Inflammatory Bowel Disease (IG-IBD) to establish Italian guidelines on the safety of currently available treatments for Crohn's disease and ulcerative colitis. These guidelines discuss the use of aminosalicylates, systemic and low bioavailability corticosteroids, antibiotics (metronidazole, ciprofloxacin, rifaximin), thiopurines, methotrexate, cyclosporine A, TNFα antagonists, vedolizumab, and combination therapies. These guidelines are based on current knowledge derived from evidence-based medicine coupled with clinical experience of a national working group.

Second Korean guidelines for the management of ulcerative colitis

Ulcerative colitis (UC) is a chronic inflammatory bowel disease characterized by a relapsing and remitting course. The direct and indirect costs of the treatment of UC are high, and the quality of life of patients is reduced, especially during exacerbation of the disease. The incidence and prevalence of UC in Korea are still lower than those of Western countries, but have been rapidly increasing during the past decades. Various medical and surgical therapies, including biologics, are currently used for the management of UC. However, many challenging issues exist, which sometimes lead to differences in practice between clinicians. Therefore, the IBD study group of the Korean Association for the Study of Intestinal Diseases established the first Korean guidelines for the management of UC in 2012. This is an update of the first guidelines. It was generally made by the adaptation of several foreign guidelines as was the first edition, and encompasses treatment of active colitis, maintenance of remission, and indication of surgery for UC. The specific recommendations are presented with the quality of evidence and classification of recommendations.

Acute severe ulcerative colitis: from pathophysiology to clinical management

Ulcerative colitis is a common chronic inflammatory disease of the colon and rectum, resulting from a dysregulated immune response towards intraluminal antigens in a genetically predisposed host. The disease has a varying extent and severity. Approximately 20% of patients with ulcerative colitis experience a severe flare during the course of their disease, requiring hospitalization. Acute severe ulcerative colitis (ASUC) is potentially a life-threatening condition that requires early recognition, hospitalization, correction of body fluids and electrolytes, and nutritional support if needed. Superimposed bacterial or viral infections need to be excluded and thromboprophylaxis should be started. Intravenous corticosteroids are the first-line treatment for this condition. Rescue treatment with ciclosporin or infliximab is indicated in patients who do not sufficiently respond to corticosteroids after 3-5 days, with close monitoring of the patients' symptoms, serum C-reactive protein and albumin levels. If medical therapy fails, timely colectomy should be performed to prevent critical complications. In this article, we review all relevant aspects of ASUC, from its pathophysiological background to modern management in clinical practice.

Corticosteroid Dosing in Pediatric Acute Severe Ulcerative Colitis: A Propensity Score Analysis

OBJECTIVES

We aimed to explore the optimal dosing of intravenous-corticosteroids (IVCS) using a robust statistical method on the largest pediatric cohort of acute severe colitis to date.

METHODS

Two hundred eighty-three children treated with IVCS for ulcerative colitis were included and studied for 1 year (46% boys, age 12.1 ± 3.9 years, disease duration 2 (interquartile range [IQR] 0-14) months, baseline Pediatric Ulcerative Colitis Activity Index 69 ± 13 points). Confounding by indication was addressed by matching high- and low-IVCS dose patients according to the propensity score method, using 3 cutoffs (1 mg · kg · methylprednisolone to 40 mg · day, 1.25 mg · kg to 50 mg · day and 2 mg · kg to 80 mg · day).

RESULTS

The median IVCS dose in the entire cohort was 1.0 mg · kg · day (IQR 0.8-1.4) and 44 mg · kg · day (32-60). Ninety-four of 283 children were matched in the low-dose cutoff (1 mg · kg · day), 218 of 283 were matched in the middle cutoff (1.25 mg · kg · day), and 86/283 in the high dose cutoff (2 mg · kg · day). No differences were found in 25 pretreatment baseline variables in the three cutoffs, implying successful matching. There were no statistical differences in the outcomes of the two lower cutoffs (including need for salvage therapy during admission and by 1 years, admission duration, and day-5 Pediatric Ulcerative Colitis Activity Index<35 points; all P > 0.05). In the high cutoff, the higher doses were somewhat better but this benefit reversed in a sensitivity analysis excluding one center. High doses were not associated with better outcome also in a propensity score-weighted regression model on the entire cohort.

CONCLUSIONS

Our data support present guidelines that doses of IVCS >1 to 1.5 mg · kg · day (maximum 40-60 mg · kg · day) are not justified in acute severe colitis.

Clinical Experience of Use of High-dose Intravenous Methylprednisolone in Children With Acute Moderate to Severe Colitis

OBJECTIVES

Treatment of acute severe colitis (ASC) has been associated with high morbidity and high colectomy rate in children. In the prebiologics era, our centre used short-term high-dose intravenous corticosteroids (IVCS) at 2 to 30 mg · kg · day. We conducted a retrospective review to compare efficacy of different dosing regimes of IVCS.

METHODS

Thirty-four children treated with IVCS for ASC were included over 8 years. Patients were studied as 2 groups with similar pretreatment patient characteristics. Group 1 (standard dose) received IVCS at 2 mg · kg · day and group 2 (high dose) received IVCS at 10 to 30 mg · kg · day. Safety, efficacy, and follow-up of the entire cohort for >1 year were studied. The median IVCS dose in the standard- and high-dose cohort was 1.5 mg · kg · day (maximum 60 mg · kg · day) and 24.8 mg · kg · day (maximum 1000 mg · kg · day), respectively.

RESULTS

Pediatric Ulcerative Colitis Activity Index scores at day 5 were significantly lower in high-dose (15, interquartile range 8.5-20) than in standard-dose IVCS (30, interquartile range 20-30). IVCS side effects were minor and reversible. Overall, medical salvage therapy was required in 5.8% (2 children) before discharge, and in 17% (6 children) at follow-up after 1 year. The colectomy rate of the entire cohort was remarkably low with 0% during admission and 11% (4 children) after 1 year, with a trend of less colectomies in high-dose (4.8%-1 child) than in standard-dose (23%-3 children).

CONCLUSIONS

Our data show that in paediatric ASC, the short-term use of high-dose IVCS is safe and effective. Prospective studies are needed to define the role of IVCS within salvage therapy protocols.

Direct and indirect healthcare resource utilization and costs associated with ulcerative colitis in a privately-insured employed population in the US

OBJECTIVE

To assess direct and indirect healthcare resource utilization and costs of privately insured US employees with ulcerative colitis (UC) from a societal perspective.

RESEARCH DESIGN AND METHODS

Employees aged 18-64 with ≥ 2 UC diagnoses and no more than one diagnosis of Crohn's disease (CD) were identified from a large, de-identified, private insurance US claims database from January 1, 2005 through March 31, 2013. Patients with UC were matched 1:1 to non-IBD controls based on demographics and index date (a randomly selected UC diagnosis). All patients were required to have continuous eligibility for ≥ 1 year before (baseline period) and after (study period) the index date. Descriptive analyses compared baseline characteristics and study period outcomes. Multivariate cost analysis adjusted for baseline comorbidities. Sub-group analyses compared patients with moderate-to-severe UC with matched controls.

MAIN OUTCOME MEASURES

Costs (2013 US dollars) were measured from a societal perspective, which included direct (patient and payer costs) and indirect (lost wages because of time away from work) costs.

RESULTS

Patients with UC (n = 4314; mean age = 45.1 years, 63.6% male) had significantly higher baseline comorbidity rates compared with controls. In the study period, significantly more patients with UC (p < 0.0001) had higher hospitalization rates (16.9% vs 6.2%), emergency department visits (31.1% vs 22.0%), prescription drug use (95.3% vs 72.0%), and work loss (100% vs 81.4%). Patients with UC also had significantly higher adjusted total direct ($15,548 vs $4812) and indirect costs ($4125 vs $1961). Patients with moderate-to-severe UC (n = 1728) had significantly (p < 0.0001) higher hospitalization rates (26.5% vs 6.2%) and adjusted total direct ($23,085 vs $4932) and indirect costs ($5666 vs $1960).

CONCLUSIONS

Patients with UC had higher resource utilization and direct and indirect costs compared with matched controls. The excess burden was greatest in patients with moderate-to-severe UC.

Current Status of the Treatment of Fulminant Colitis

Fulminant colitis is not a well-defined entity, that constitutes a severe complication. It usually occurs in the course of úlcerative colitis and Clostridium difficile colitis. A multidisciplinary management combining gastroenterologist and surgeons is crucial with intensive medical treatment and early surgery in non-responders. It is important to distinguish if we are facing a flare of IBD or, on the contrary, it is an infectious colitis, due to the fact that although general therapeutic measures to adopt will be the same, they will demand opposed specific measures.

Bolus administration of steroid therapy is more favorable than the conventional use in preventing decrease of bone density and the increase of body fat percentage in patients with inflammatory bowel disease

INTRODUCTION

The effects of short course of corticosteroids on the metabolic processes and bone formation has not been well studied. Our aim was to compare the efficacy, the side effects and the bone and lipid metabolisms in IBD patients using bolus or conventional tapering of methylprednisolone for 12 weeks.

PATIENTS AND METHODS

Nineteen IBD patients received intravenous methylprednisolone of 1mg/kg for 5 days tapered by 4 mg per week. Patients were prospectively randomized in two groups. In "conventional" group (I) steroids were given daily. In "pulse" group (II) weekly doses of steroids were given on special days of the week. The body mass index (BMI) was measured before and after the corticosteroid therapy. Blood samples were collected to assess glucose level, electrolytes, cholesterol and triglyceride levels, inflammatory parameters, cortisol, osteocalcin and crosslaps values. Total body composition analysis was performed at the beginning and at the end of the steroid therapy.

RESULTS

In Group I, BMI increased, total body bone density decreased significantly at the end of the steroid therapy. Body fat percent showed a tendency to be higher at the end of steroid therapy in Group I. Cholesterol level increased significantly in Group I patients. The decrease in serum cortisol level was more remarkable in Group I vs. Group II after steroid therapy. Less side-effect occurred in Group II vs. Group I.

DISCUSSION

Our results suggest that bolus tapering of corticosteroids may have more favorable short term outcome than conventional tapering that may revolutionize steroid therapy in IBD.

Fulminant colitis

Fulminant colitis is an ill-defined entity that is usually viewed as the most severe form of uncomplicated acute colitis. It usually occurs in the course of ulcerative colitis and infectious colitis, but can also be seen in other forms of colitis. Every patient with clinical criteria for severe or fulminant colitis should be approached in a systematic way, based on two premises - intense medical treatment and early surgery in non-responders.

Impact and indication of early systemic corticosteroids for very severe community-acquired pneumonia

Background

The efficacy of systemic corticosteroids in community-acquired pneumonia (CAP) has not yet been confirmed. We prospectively investigated the clinical features of patients treated with early adjunctive systemic corticosteroids and its clinical impact in very severe CAP.

Methods

One hundred and one consecutive CAP patients having a pneumonia severity index of >130 points were enrolled from August 2010 through February 2013. Early adjunctive systemic corticosteroids were defined as administration of systemic corticosteroids equivalent to prednisone of ≥20 mg/day added to initial antibiotics. The multivariate analysis was performed to evaluate the independent factors associated with mortality.

Results

Thirty-two patients (31.7%) died within 28 days of admission. Early adjunctive systemic corticosteroids were administered in 30 patients (29.7%), who more frequently had alteration of mental status, serious respiratory failure, or underlying lung diseases and received fluoroquinolones as initial antibiotics. In most patients treated with early adjunctive systemic corticosteroids, the dosage was less than 60 mg/day of an equivalent to prednisone by bolus intravenous infusion for a period shorter than 8 days. The occurrence of adverse events did not differ between the groups. Factors independently associated with mortality were blood urea nitrogen (hazard ratio [HR] 1.02, 95% confidence interval [CI] 1.00–1.04), serum albumin (HR 0.44, 95% CI 0.22–0.86), a requirement for intensive care (HR 4.93, 95% CI 1.75–13.87), and the therapy with early adjunctive systemic corticosteroids (HR 0.29, 95% CI 0.11–0.81).

Conclusion

Early adjunctive systemic corticosteroids may have an effect to reduce the mortality in very severe CAP, although a larger-scale study is necessary.

My treatment approach to the management of ulcerative colitis

Ulcerative colitis diagnosis and management represent a challenge for clinicians. The disguises of ischemia and acute infectious colitis continue to confound the diagnosis. The therapeutic options have remarkably expanded in the way of immunomodulators, biologics, or ileoanal pouch surgery, yet all carry potential considerable risks. These risks can confuse and impair patient acceptance, particularly elderly patients and men younger than 30 years. Predictors of outcome of medical and surgical therapy have improved but are far from complete. Nevertheless, therapies focused on the specific patient's condition continue to offer hope.

[Guidelines for the management of ulcerative colitis]

Ulcerative colitis (UC) is a chronic inflammatory bowel disorder characterized by a relapsing and remitting course. The quality of life can decreases significantly during exacerbations of the disease. The incidence and prevalence of UC in Korea are still lower than those of Western countries, but have been rapidly increasing during the past decades. Various medical and surgical therapies are currently used for the management of UC. However, many challenging issues exist and sometimes these lead to differences in practice between clinicians. Therefore, Inflammatory Bowel Diseases (IBD) Study Group of Korean Association for the Study of Intestinal Diseases (KASID) set out the Korean guidelines for the management of UC. These guidelines are made by the adaptation using several foreign guidelines and encompass treatment of active colitis, maintenance of remission and indication for surgery in UC. The specific recommendations are presented with the quality of evidence. These are the first Korean treatment guidelines for UC and will be revised with new evidences on treatment of UC.

Management of acute colitis and toxic megacolon

Severe colitis is a well-defined condition that can develop in patients afflicted with ulcerative colitis, but typically responds to a variety of medical therapies. Operative intervention is warranted when massive hemorrhage, perforation, or peritonitis complicates the clinical scenario or medical therapy fails to control the disease. Of the operative options, total/subtotal colectomy and end ileostomy is the usual procedure of choice especially if the operation can be performed through a laparoscopic approach.

Treatment of hospitalized adult patients with severe ulcerative colitis: Toronto consensus statements

OBJECTIVES

The objective of this study was to provide updated explicit and relevant consensus statements for clinicians to refer to when managing hospitalized adult patients with acute severe ulcerative colitis (UC).

METHODS

The Canadian Association of Gastroenterology consensus group of 23 voting participants developed a series of recommendation statements that addressed pertinent clinical questions. An iterative voting and feedback process was used to do this in conjunction with systematic literature reviews. These statements were brought to a formal consensus meeting held in Toronto, Ontario (March 2010), when each statement was discussed, reformulated, voted upon, and subsequently revised until group consensus (at least 80% agreement) was obtained. The modified GRADE (Grading of Recommendations Assessment, Development, and Evaluation) criteria were used to rate the strength of recommendations and the quality of evidence.

RESULTS

As a result of the iterative process, consensus was reached on 21 statements addressing four themes (General considerations and nutritional issues, Steroid use and predictors of steroid failure, Cyclosporine and infliximab, and Surgical issues).

CONCLUSIONS

Key recommendations for the treatment of hospitalized patients with severe UC include early escalation to second-line medical therapy with either infliximab or cyclosporine in individuals in whom parenteral steroids have failed after 72 h. These agents should be used in experienced centers where appropriate support is available. Sequential therapy with cyclosporine and infliximab is not recommended. Surgery is an option when first-line steroid therapy fails, and is indicated when second-line medical therapy fails and/or when complications arise during the hospitalization.

Acute and chronic megacolon

Megacolon, defined as dilation of the abdominal colon, may occur acutely or in a chronic form. Acute megacolon that occurs in association with severe inflammation of the colon is known as toxic megacolon, whereas acute megacolon without obvious colonic disease is known as Ogilvie's syndrome. The pathophysiology and management of toxic megacolon, Ogilvie's syndrome, and chronic megacolon in adults differ significantly, and it is critically important to distinguish among these entities. Toxic megacolon is a medical emergency that requires coordinated intensive medical and surgical management. In addition to vigorous resuscitation with fluids, electrolytes, and blood products, medical treatment consists of parenteral corticosteroids, broad-spectrum antibiotics, and close monitoring of the patient. Surgical intervention is required if there is no improvement, or deterioration after 12 to 24 hours of intensive medical management, or if there is evidence of colon perforation. Ogilvie's syndrome usually occurs in hospitalized patients with serious underlying medical or surgical illnesses. Management is directed at preventing ischemia and perforation of the distended colon. Supportive therapy includes nasogastric suction, correction of fluid and electrolyte imbalances, stopping potentially aggravating medications, and decompressing the colon with a rectal tube and positional changes. Intravenous neostigmine is the only pharmacologic agent of proven efficacy; colonoscopic decompression is an alternative in patients who do not respond to neostigmine or who have conditions that contraindicate its use. Daily oral administration of polyethylene glycol electrolyte solutions appears to decrease the relapse rate after initial decompression is achieved. Chronic megacolon in adults represents advanced colon failure that does not respond to pharmacologic stimulation. Goals of therapy are to cleanse the colon, prevent impaction, and minimize stool volume and gas buildup. For patients with disabling symptoms, surgical exclusion of the colon, decompression and antegrade enemas via cecostomy, or subtotal or segmental resection may be palliative.

Ulcerative colitis: current treatment strategies and future prospects

Ulcerative colitis (UC) is a disease of unknown etiology characterized by inflammation of the mucosa and occasionally the submucosa of the colon. Conventional drug therapy for UC involves use of aminosalicylates, corticosteroids, azathioprine/6-mercaptopurine, cyclosporine and anti-tumor necrosis factor therapy. Alternative therapies include probiotics, nicotine and fish oil. Drugs like tacrolimus, rosiglitazone and Trichuris suis ova are being evaluated for use in UC patients. With the new biologic agents, new treatment options for UC continue to evolve. In this article we will discuss the conventional drugs, the alternative therapies and the management strategies according to the severity and extent of UC.

Consensus for managing acute severe ulcerative colitis in children: a systematic review and joint statement from ECCO, ESPGHAN, and the Porto IBD Working Group of ESPGHAN

OBJECTIVES

Acute severe ulcerative colitis (ASC) is a potentially life-threatening disease. We aimed to formulate guidelines for managing ASC in children based on systematic review of the literature and robust consensus process. This manuscript is a product of a joint effort of the ECCO (European Crohn's and Colitis Organization), the Pediatric Porto Inflammatory Bowel Disease (IBD) Working group of ESPGHAN (European Society of Pediatric Gastroenterology, Hepatology, and Nutrition) and ESPGHAN.

METHODS

A group of 19 experts in pediatric IBD participated in an iterative consensus process including two face-to-face meetings. A total of 17 predefined questions were addressed by working subgroups based on a systematic review of the literature.

RESULTS

The recommendations and practice points were eventually endorsed with a consensus rate of at least 95% regarding: definitions, initial evaluation, standard therapy, timing of second-line therapy, the role of endoscopic evaluation and heparin prophylaxis, how to administer second-line medical therapy, how to assess response, surgical considerations, and discharge recommendations. A management flowchart is presented based on daily scoring of the Pediatric Ulcerative Colitis Activity Index (PUCAI), along with 28 formal recommendations and 34 practice points.

CONCLUSIONS

These guidelines provide clinically useful points to guide the management of ASC in children. Taken together, the recommendations offer a standardized protocol that allows effective monitoring of disease progress and timely treatment escalation when needed.

Acute severe ulcerative colitis in children: a systematic review

Pediatric ulcerative colitis (UC) has a more severe phenotype, reflected by more extensive disease and a higher rate of acute severe exacerbations. The pooled steroid-failure rate among 291 children from five studies is 34% (95% confidence interval [CI]: 27%-41%). It is suggested that corticosteroids should be dosed between 1-1.5 mg/kg up to 40-60 mg daily. Food restriction has a limited role in severe UC and should be generally discouraged in children who do not have a surgical abdomen. Appraisal of radiologic findings in children must recognize the variation in colonic width with age and size. Data suggest that the Pediatric UC Activity Index (PUCAI), determined at day 3, should be used to screen for patients likely to fail corticosteroids (>45 points), and at day 5 to dictate the introduction of second-line therapy (>65-70 points). Cyclosporine is successful in children with severe colitis but its use should be restricted to 3-4 months while bridging to thiopurine treatment (pooled short-term success rate 81% [95% CI: 76%-86%]; n = 94 from eight studies). Infliximab may be as effective as cyclosporine (75% pooled short-term response (95% CI: 67%-83%); n = 126, six studies) with a pooled 1-year response of 64% (95% CI: 56%-72%). In toxic megacolon, in patients refractory to one salvage medical therapy, and in chronic severe disease, colectomy may be preferred. Decision-making regarding colectomy in children must consider the toxicity of medication consumed over many future years, the quality of life and self-image associated with either choice, as well as both functional outcomes and, in females, fertility following pouch procedures.
