Lack of increase in postoperative complications with low-dose methotrexate therapy in patients with rheumatoid arthritis undergoing elective orthopedic surgery

Japan College of Rheumatology guidance for the use of methotrexate in patients with rheumatoid arthritis: Secondary publication

Methotrexate (MTX), the anchor drug in the current treatment strategy for rheumatoid arthritis (RA), was first approved for the treatment of RA in Japan in 1999 at a recommended dose of 6-8 mg/week. The approved maximum dose of MTX has been 16 mg/week since February 2011 when MTX was approved as a first-line drug in the treatment of RA. Recent evidence of MTX-polyglutamate concentration in the red blood cells of Japanese patients with RA justifies the current daily use of MTX in Japan. Additionally, after a nationwide clinical trial, a subcutaneous MTX injection formula (7.5-15 mg/week) was approved for RA treatment in September 2022. Therefore, in March 2023, a subcommittee of the Japan College of Rheumatology updated the guidance (formerly 'guidelines') for the use of MTX in Japanese patients with RA. This article, an abridged English translation summarizing the 2023 update of the Japan College of Rheumatology guidance for the use of MTX and management of patients with RA, will be helpful to both Japanese and global rheumatology communities.

Australian recommendations on perioperative use of disease-modifying anti-rheumatic drugs in people with inflammatory arthritis undergoing elective surgery

Disease-modifying anti-rheumatic drugs (DMARDs) are effective treatments for inflammatory arthritis but carry an increased risk of infection. For patients undergoing surgery, there is a need to consider the trade-off between a theoretical increased risk of infection with continuation of DMARDs perioperatively versus an increased risk of disease flare if they are temporarily withheld. We used the Grading of Recommendations Assessment, Development and Evaluation methodology to develop recommendations for perioperative use of DMARDs for people with inflammatory arthritis undergoing elective surgery. The recommendations form part of the National Health and Medical Research Council-endorsed Australian Living Guideline for the Pharmacological Management of Inflammatory Arthritis. Conditional recommendations were made against routinely discontinuing conventional synthetic and biologic (b) DMARDs in the perioperative period but to consider temporary discontinuation of bDMARDs in individuals with a high risk of infection or where the impact of infection would be severe. A conditional recommendation was made in favour of temporary discontinuation of targeted synthetic DMARDs in the perioperative period.

Preoperative Management of Medications for Rheumatologic and HIV Diseases: Society for Perioperative Assessment and Quality Improvement (SPAQI) Consensus Statement

Perioperative medical management is challenging because of the rising complexity of patients presenting for surgical procedures. A key part of preoperative optimization is appropriate management of long-term medications, yet guidelines and consensus statements for perioperative medication management are lacking. Available resources use recommendations derived from individual studies and do not include a multidisciplinary focus on formal consensus. The Society for Perioperative Assessment and Quality Improvement identified a lack of authoritative clinical guidance as an opportunity to use its multidisciplinary membership to improve evidence-based perioperative care. The Society for Perioperative Assessment and Quality Improvement seeks to provide guidance on perioperative medication management that synthesizes available literature with expert consensus. The aim of this consensus statement is to provide practical guidance on the preoperative management of immunosuppressive, biologic, antiretroviral, and anti-inflammatory medications. A panel of experts including hospitalists, anesthesiologists, internal medicine physicians, infectious disease specialists, and rheumatologists was appointed to identify the common medications in each of these categories. The authors then used a modified Delphi process to critically review the literature and to generate consensus recommendations.

Preoperative Optimization and Tips to Avoiding Surgical Complications Before the Incision

In preparation for surgery, it is important for surgeons to have a detailed discussion with patients about the risks, benefits, and alternatives to surgery. Patient optimization, ensuring the patient is in the best medical condition before surgery, is also an important aspect of patient care that the surgeon must consider. Although complications cannot be eliminated, there are often opportunities to optimize patients, so these risks can be minimized based on current evidence-based medicine. To minimize the risk of complications, the surgeon should take an active role in each step of the patient's care beginning with the history and physical examination, obtaining the correct preoperative labs, and continuing through positioning, draping, and prepping before making an incision.

Methotrexate in inflammatory bowel disease: A primer for gastroenterologists

Methotrexate is an antineoplastic agent that is also used at lower doses for anti-inflammatory properties. Along with thiopurines (azathioprine and 6-mercaptopurine), it has historically been an important part of pharmacological treatment for patients with inflammatory bowel disease. Despite an increase in therapeutic options, these immunomodulators continue to play important roles in the management of inflammatory bowel disease, used either as a monotherapy in mild to moderate cases or in combination with monoclonal antibodies to prevent immunogenicity and maintain efficacy. In light of data linking the use of thiopurines with the risk of malignancies, methotrexate has regained attention as a potential alternative. In this article, we review data on the pharmacology, safety, and efficacy of methotrexate and discuss options for the positioning of methotrexate alone, or in combination, in therapeutic algorithms for Crohn's disease and ulcerative colitis.

Perioperative Management of Antirheumatic Medications in Patients with RA and SLE Undergoing Elective Foot and Ankle Surgery: A Critical Analysis Review

»

Recent literature has shown that continued use rather than discontinuation of various antirheumatic agents throughout the perioperative period may present an opportunity to mitigate the risks of elective surgery.

»

For patients with rheumatoid arthritis and systemic lupus erythematosus, perioperative management of medication weighs the risk of infection against the risk of disease flare when immunosuppressive medications are withheld.

»

Broadly speaking, current evidence, although limited in quality, supports perioperative continuation of disease-modifying antirheumatic drugs, whereas biologic drugs should be withheld perioperatively, based on the dosing interval of the specific drug.

»

For any withheld biologic drug, it is generally safe to restart these medications approximately 2 weeks after surgery, once the wound shows evidence of healing, all sutures and staples have been removed, and there is no clinical evidence of infection. The focus of this recommendation applies to the optimization of wound-healing, not bone-healing.

»

In most cases, the usual daily dose of glucocorticoids is administered in the perioperative period rather than administering "stress-dose steroids" on the day of surgery.

[Perioperative management in the treatment of trauma for rheumatics under immunosuppression]

With an almost 3.5% manifestation rate in Germany, rheumatoid arthritis is a relatively frequent disease. Due to the involvement of diverse locations on the skeleton and often multiple comorbidities, treatment of these patients in cases of acute trauma potentially represents a substantial risk. The anti-inflammatory drug treatment harbors dangers, such as delayed wound healing and infections in the perioperative management of these patients. In an emergency a modification of the basic anti-inflammatory medication is hardly possible, so that the postoperative phase after trauma surgery is of special importance. If necessary, orthopedic or internist rheumatologists should be consulted for additional support. Absolute and urgent surgical interventions do not constitute a contraindication with respect to the antirheumatic medication but should be considered in the assessment of the perioperative risk profile. A close cooperation with anesthesia, the meticulous control of intraoperative positioning and postoperative management are of particular importance.

[Surgery for inflammatory rheumatic joint destruction]

Orthopaedic and traumatologic involvement in patients with rheumatic diseases require extensive knowledge of these immunologically impairing illnesses. This concerns both the handling of medication and conservative treatment. The destructive processes of the joints and the spine follow established pathways. Various operating procedures are helpful depending on the stage of articular destruction. The special features of the entire perioperative management of affected persons has to be observed. Soft tissue surgical interventions are followed by arthrodesis or arthroplasty in later courses of destruction. In Germany, the orthopaedic rheumatologist specializes in the conservative and surgical treatment of inflammatory systemic diseases. Audited centres for operative interventions of the German Society for Orthopaedic Rheumatology (DGORh) seem to be the best fit for this purpose.

Perioperative Management of Patients with Inflammatory Rheumatic Diseases Undergoing Major Orthopaedic Surgery: A Practical Overview

Patients with inflammatory rheumatic diseases often need orthopaedic surgery due to joint involvement. Total hip replacement and total knee replacement are frequent surgical procedures in these patients. Due to the complexity of the inflammatory rheumatic diseases, the perioperative management of these patients must envisage a multidisciplinary approach. The frequent association with extraarticular comorbidities must be considered when evaluating perioperative risk of the patient and should guide the clinician in the decision-making process. However, guidelines of different medical societies may vary and are sometimes contradictory. Orthopaedics should collaborate with rheumatologists, anaesthesiologists and, when needed, cardiologists and haematologists with the common aim of minimising perioperative risk in patients with inflammatory rheumatic diseases. The aim of this review is to provide the reader with simple practical recommendations regarding perioperative management of drugs such as disease-modifying anti-rheumatic drugs, corticosteroids, non-steroidal anti-inflammatory drugs and tools for a risk stratification for cardiovascular and thromboembolic risk based on current evidence for patients with inflammatory rheumatic diseases.

Perioperative use of immunosuppressive medications in patients with Crohn's disease in the new "biological era"

Crohn’s disease (CD) is characterized by transmural inflammation of the gastrointestinal tract leading to inflammatory, stricturing and/or and fistulizing disease. Once a patient develops medically refractory disease, mechanical obstruction, fistulizing disease or perforation, surgery is indicated. Unfortunately, surgery is not curative in most cases, underscoring the importance of bowel preservation and adequate perioperative medical management. As many of the medications used to treat CD are immunosuppressive, the concern for postoperative infectious complications and anastomotic healing are particularly concerning; these concerns have to be balanced with preventing and treating residual or recurrent disease. We herein review the available literature and make recommendations regarding the preoperative, perioperative and postoperative administration of immunosuppressive medications in the current era of biological therapy for CD. Standardized algorithms for perioperative medical management would greatly assist future research for optimizing surgical outcomes and preventing disease recurrence in the future.

Effect of methotrexate on bone and wound healing

INTRODUCTION

Methotrexate (MTX) is one of the most commonly used disease modifying drugs administered for wide spectrum of conditions. Through the expansion of the indications of MTX use, an increasing number of patients nowadays attend orthopaedic departments receiving this pharmacological agent. The aim of this manuscript is to present our current understanding on the effect of MTX on bone and wound healing. Areas covered: The authors offer a comprehensive review of the existing literature on the experimental and clinical studies analysing the effect of MTX on bone and wound healing. The authors also analyse the available literature and describe the incidence of complications after elective orthopaedic surgery in patients receiving MTX. Expert opinion: The available experimental data and clinical evidence are rather inadequate to allow any safe scientific conclusions on the effect of MTX on bone healing. Regarding wound healing, in vitro and experimental animal studies suggest that MTX can adversely affect wound healing, whilst the clinical studies show that lose-dose MTX is safe and does not affect the incidence of postoperative wound complications.

Surgical Outcome of Cerebral Aneurysm Clipping Treated with Immunosuppressants: Report of 11 Cases and Review of the Literature

There are no reports on the outcomes of clippings in patients who receive immunosuppressants, for example, due to connective tissue diseases or following organ transplantation. We thoroughly reviewed these cases focusing on the perioperative management phase. The study included 11 patients with intracranial aneurysms who were taking immunosuppressants; between 2007 and 2014. We performed 12 clipping surgeries. Their clinical records were reviewed for age and gender, aneurysms' location and size, perioperative management of the immunosuppressive drugs, and surgical complications. The study included nine females and two males, aged between 52 and 71 years (mean 60.1 ± 8.5 years). The clinical presentation in five cases was subarachnoid hemorrhage (SAH); the aneurysm was incidentally diagnosed in six patients (7 aneurysms). The reasons for taking immunosuppressants were autoimmune disorder in nine patients and liver transplantation in two patients. Daily intake of oral immunosuppressants for the patients with liver transplantation was discontinued for 2-4 days, and no infectious complications were evidenced. The weekly course of immunosuppressive drugs for the patients with autoimmune disorder was continued in eight of nine patients. Caution must be exercised when considering the suitability of clipping for patients taking immunosuppressants, but surgery outcomes are generally favorable; when operative treatment is required, we believe it to be comparatively safe, if the perioperative management is conducted in close collaboration with the relevant departments.

New WHO recommendations on preoperative measures for surgical site infection prevention: an evidence-based global perspective

Surgical site infections (SSIs) are among the most preventable health-care-associated infections and are a substantial burden to health-care systems and service payers worldwide in terms of patient morbidity, mortality, and additional costs. SSI prevention is complex and requires the integration of a range of measures before, during, and after surgery. No international guidelines are available and inconsistencies in the interpretation of evidence and recommendations of national guidelines have been identified. Given the burden of SSIs worldwide, the numerous gaps in evidence-based guidance, and the need for standardisation and a global approach, WHO decided to prioritise the development of evidence-based recommendations for the prevention of SSIs. The guidelines take into account the balance between benefits and harms, the evidence quality, cost and resource use implications, and patient values and preferences. On the basis of systematic literature reviews and expert consensus, we present 13 recommendations on preoperative preventive measures.

Preoperative Use of Methotrexate and the Risk of Early Postoperative Complications in Patients with Inflammatory Bowel Disease

BACKGROUND

Preoperative immunosuppressive use among patients with Crohn's disease or ulcerative colitis may lead to an increased risk of postoperative complications. There is limited information on the preoperative safety profile of methotrexate (MTX) in inflammatory bowel disease (IBD).

METHODS

A retrospective study of patients who underwent abdominal surgery for IBD between 1993 and 2012 was performed and records abstracted, including preoperative use of MTX, azathioprine/6-mercaptopurine, antitumor necrosis factor, and corticosteroids. Early postoperative complications, including death, septic, and nonseptic complications were identified. A meta-analysis was also performed on the use of preoperative MTX in patients with IBD or rheumatoid arthritis.

RESULTS

A total of 180 patients with IBD underwent abdominal surgery. A total of 15 patients received MTX either monotherapy or in combination therapy. Total early postoperative complications were identified in 71 (39%) patients, specifically 5 patients on oral MTX. A total of 51 cases (28%) of septic complications and 20 (11%) nonseptic. No significant association between the use of MTX and early postoperative complications was found. The odds ratio (OR) of complications versus no complications associated with MTX was 0.75 (95% CI, 0.25-2.29) and with azathioprine/6-mercaptopurine, OR 1.48 (95% CI, 0.77-2.84). The odds of a septic complication associated with MTX were 0.58 (95% CI, 0.09-3.73), and higher in azathioprine/6-mercaptopurine, OR 3.97 (95% CI, 1.03-15.3). Our meta-analysis also did not reveal an increased risk of postoperative complications in IBD or rheumatoid arthritis on preoperative MTX (OR 0.62, 95% CI, 0.34-1.15).

CONCLUSIONS

Preoperative MTX use does not seem to be associated with early postoperative complications in IBD.

[Juvenile rheumatoid diseases: Endoprosthetic care of destroyed hip joints]

BACKGROUND

Patients with juvenile idiopathic arthritis (JIA) often suffer from involvement of the hip joints, with joint destruction and related functional limitations, making hip replacement necessary.

OBJECTIVES

To discover what special features are to be expected in patients with JIA and hip arthroplasty and what impact they have on surgical indication, choice of implant, and technique.

METHODS

Selective literature review and evaluation of our patient population.

RESULTS

Compared with osteoarthritis patients, JIA patients are on average much younger at the time of hip replacement. Owing to the onset of the disease in childhood or adolescence and the frequent glucocorticoid therapy, growth disorders or abnormal anatomical findings are common in these patients. Bone density is often reduced at an early age. The perioperative management of medication has to be planned. Special implants for patients with rheumatic diseases do not exist, but the above peculiarities of this group of patients should be considered for surgical procedure and choice of implant and material. Overall, the results of hip arthroplasty in juvenile rheumatic diseases, in terms of pain relief and functional improvement, are good. The limited life of the arthroplasty is problematic.

CONCLUSIONS

By relieving pain, improvement of the range of motion and activity level very high patient satisfaction is usually achieved by hip arthroplasty in JIA patients. In the case of involvement of the contralateral hip or the ipsilateral knee joint it may be useful to perform a simultaneous, single-stage joint replacement of both joints.

Perioperative Treatment of Patients with Rheumatoid Arthritis

Rheumatoid arthritis is an autoimmune disease mediated by a widespread chronic systematic inflammatory process that causes joint deterioration, which leads to pain, disability, and poor quality of life. The increased use of disease-modifying antirheumatic drugs has been shown to markedly slow disease progression, which has translated into a decrease in the need for orthopaedic intervention in this population. However, a substantial percentage of patients with the disease fail optimal pharmacologic treatment and still require surgical intervention. A thorough understanding of medical considerations in these patients and improved knowledge of the medical complications caused by the disease process and the pharmacologic therapy used to treat it may lead to improved preoperative planning and medical clearance, which may ultimately improve the overall postoperative outcome.

[Recommendations of the German Society for Rheumatology on the perioperative approach under therapy with DMARDs and biologicals in inflammatory rheumatic diseases]

BACKGROUND

The perioperative administration of antirheumatic medication can lead to an increased risk of infection and to a malfunction in wound healing up to a manifest infection; however, the termination of antirheumatic therapy can result in a flare up of the disease. Both situations can endanger the success of the operation, particularly in arthroplasty.

METHOD

The recommendations have been developed and approved by the Pharmacotherapy Commission of the German Society for Rheumatology following a systematic literature search (as of 30 April 2013) and a consensus process.

RESULTS

As very little data with sufficiently high evidence are available, the present recommendations should be considered as having an advisory quality and an individual risk assessment should always be carried out. Classical disease-modifying antirheumatic drugs (DMARD), such as methotrexate can be continued in normal cases but whether this is also true for leflunomide is still undecided. For biologicals a break of two half-life periods before the operation is recommended. The therapy can be continued after wound healing has been completed and when there are no signs of infection.

Perioperative care for patients with rheumatic diseases

The perioperative care of patients with rheumatic diseases is hampered by a lack of evidence-based recommendations. Rheumatologists are called upon to 'clear' their patients for surgery, yet the evidence upon which to base decisions is fractionated and inconsistent. We have systematically reviewed the current literature and developed suggestions for three key areas that require particular deliberations in patients with rheumatic diseases scheduled for surgery: the management of cardiovascular risk, use of immunosuppressive drugs, and states of altered coagulation. For patients with rheumatic diseases associated with increased cardiovascular risk, such as rheumatoid arthritis and systemic lupus erythematosus, we suggest following the American College of Cardiology-American Heart Association guidelines using the underlying disease as a risk modifier. Most evidence suggests a neutral effect of conventional DMARDs in the perioperative period, with no need to discontinue them prior to surgery. Conversely, we suggest minimizing perioperative steroid use and unnecessary 'steroid preps'. The potential benefits of discontinuing biologic drugs in the perioperative setting needs to be carefully balanced with the risks associated with a disease flare. We discuss the American College of Chest Physicians guidelines, which classify individuals with antiphospholipid antibody syndrome as high-risk patients for perioperative thrombosis who are likely to require bridging therapy in most perioperative settings.

Risk of postoperative complications in rheumatoid arthritis relevant to treatment with biologic agents: a report from the Committee on Arthritis of the Japanese Orthopaedic Association

PURPOSE

Since biologic agents were introduced to treat rheumatoid arthritis (RA) in 2003, the number of orthopedic surgical procedures under treatment with biologic agents has been increasing in Japan. However, whether biologic agents cause an increase in the prevalence of postoperative complications is as yet unknown. The Committee on Arthritis of the Japanese Orthopedic Association investigated the prevalence of postoperative complications in patients with RA in teaching hospitals in Japan.

METHODS

Between January 2004 and November 2008, surveillance forms about medications and surgical procedures in patients with RA were sent to 2,019 teaching hospitals. Data were analyzed by the Rheumatoid Arthritis Committee.

RESULTS

Biologic agents were administered to RA patients in 632 of 1,245 hospitals (50.8%); 430 of the 1,245 hospitals (34.5%) used surgical intervention under treatment with biologic agents. The number of surgical procedures under treatment with biologic agents was 3,468, and the prevalence of infection was 1.3% (46 cases). The prevalence of infection was 1.0% (567 procedures) in 56,339 procedures under treatment with nonbiologic disease-modifying anti-rheumatic drugs. There were no significant differences between biological and nonbiological treatment groups with respect to the prevalence of infection. In the joint arthroplasty group, the number of procedures under biological and nonbiological treatment was 1,626 and 29,903, and the prevalence of infection was 2.1% (34 procedures) and 1.0% (298 procedures), respectively. There was a significant difference between groups. The odds ratio was 2.12 (95% confidence interval 1.48-3.03, P < 0.0001).

CONCLUSION

The chance of having biological treatment with joint arthroplasty was more than twofold greater in patients with surgical-site infections compared with those treated with nonbiologic agents. Caution is required for surgical procedure, perioperative course, and obtaining consent for joint arthroplasty for patients with RA undergoing surgery under biological agents.
