A double-blind study of perioperative steroid requirements in secondary adrenal insufficiency

Comparison of two strategies of glucocorticoid withdrawal in patients with rheumatoid arthritis in low disease activity (STAR): a randomised, placebo- controlled, double-blind trial

OBJECTIVES

To compare two strategies-a hydrocortisone replacement strategy and a prednisone tapering strategy-for their success in glucocorticoid discontinuation in patients with rheumatoid arthritis (RA) with low disease activity (LDA).

METHODS

The Strategies for glucocorticoid TApering in Rheumatoid arthritis (STAR) study was a double- blind, double-placebo randomised controlled trial including patients with RA receiving a stable dose of glucocorticoid 5 mg/day for ≥3 months and were in LDA for ≥3 months. Patients were randomly assigned in a 1:1 ratio to either replace prednisone with 20 mg/day of hydrocortisone for 3 months, then reduce to 10 mg/day for 3 months before discontinuation or to taper prednisone by 1 mg/day every month until complete discontinuation, contingent on maintaining LDA. The primary outcome was the percentage of patients achieving glucocorticoid discontinuation at 12 months. Other secondary outcomes were proportion of flares, need for additional glucocorticoid use, disease activity, patient-reported outcomes and the results of adrenocorticotropic hormone (ACTH) stimulation tests.

RESULTS

Of the 102 patients randomised in the trial (mean age 62.4 years, 70.6% females), 53 had hydrocortisone replacement and 49 tapered prednisone. At 12 months, 29 patients (55%) in the hydrocortisone replacement group and 23 patients (47%) in the prednisone tapering group achieved glucocorticoid discontinuation (p=0.4). No difference was observed between groups in the secondary outcomes. No cases of acute adrenal insufficiency were observed; however, 17 patients still had an abnormal ACTH stimulation test at 12 months, with no differences between arms.

CONCLUSION

A hydrocortisone replacement strategy was not superior to a prednisone tapering strategy for achieving glucocorticoid discontinuation success in patients with RA in LDA.

Endocrine Care for the Surgical Patient: Diabetes Mellitus, Thyroid and Adrenal Conditions

Patients with hyperglycemia, thyroid dysfunction, and adrenal insufficiency face increased perioperative risk, which may be mitigated by appropriate management. This review addresses preoperative glycemic control, makes evidence-based recommendations for the increasingly complex perioperative management of noninsulin diabetes medications, and provides guideline-supported strategies for the perioperative management of insulin, including suggested indications for continuous intravenous insulin. The authors propose a strategy for determining when surgery should be delayed in patients with thyroid dysfunction and present a matrix for managing perioperative stress dose corticosteroids based on the limited evidence available.

Steroid supplementation before minor oral surgical procedures in patients taking long-term glucocorticoids: A triple-blinded, randomized, placebo-controlled trial

BACKGROUND

Patients undergoing long-term glucocorticoid therapy are administered additional glucocorticoids before minor dental procedures, although this is not supported by evidence. The authors designed this study to validate the hypothesis that routine blanket glucocorticoid supplementation is unnecessary during minor oral surgical procedures under local anesthesia.

METHODS

The authors recruited 270 patients into 3 groups (1:1:1 allocation) from the dental outpatient department. Primary outcomes were changes in hemodynamic parameters and frequency of adverse events among the 3 groups. The secondary outcome was the association of preprocedural stress and procedural pain with periprocedural adverse events in the long-term glucocorticoid therapy group (groups I and II).

RESULTS

No clinically relevant changes in hemodynamic parameters among the 3 groups were found. The authors also found low periprocedural adverse events in all 3 groups combined (n = 1), so they did not explore the secondary outcomes further.

CONCLUSIONS

Among patients undergoing long-term glucocorticoid therapy for indications other than primary adrenal insufficiency, elective minor oral surgical procedures can be performed safely with only their daily dose of glucocorticoid when their medical conditions are optimized. Routine additional glucocorticoid supplementation appears unnecessary. The results of the study also revealed opportunities for value addition by means of integrating oral health care with medical follow-up for patients with multiple co-occurring medical conditions.

PRACTICAL IMPLICATIONS

Routine blanket glucocorticoid supplementation among patients taking a long-term glucocorticoid for indications other than primary adrenal insufficiency appears unnecessary before minor oral surgical procedures under local anesthesia. This clinical trial was registered at Clinical Trial Registry-India. The registration number is CTRI/2017/02/007779.

Is Preoperative Adrenal Insufficiency Screening Necessary for Cardiovascular Thoracic Surgery Patients?

Background: The association between adrenal insufficiency (AI) and the treatment outcomes of cardiothoracic surgery patients has been little reported. The aims of this study were to investigate the incidence of AI and to compare the post-surgical outcomes of patients with perioperatively treated AI and patients with a normal adrenal response. Methods: A 1.5-year prospective study was conducted in 98 patients scheduled for cardiothoracic surgery. Patients were categorized as either AI or normal-adrenal-response patients. Those with AI were treated with stress doses of glucocorticoid perioperatively. The post-surgical outcomes of patients with AI and of those with a normal adrenaline response were analyzed using multivariable analysis. Results: The overall incidence of AI was 34.7%. There were no statistically significant differences in post-surgical outcomes, including prolonged hospital stay, postoperative infection, prolonged inotropic drug use and relative AI, between the two groups. Only the rate of hyperglycemia requiring insulin infusion was significantly higher in the AI group than in the non-AI group (OR = 14.15, 95% CI = 1.44-138.60, p = 0.02). Conclusions: The proper diagnosis and management of AI can result in surgical outcomes in AI patients comparable to those of normal-adrenal-response patients. Non-life-threatening hyperglycemia requiring insulin infusion was found only in the AI group.

Perioperative Evaluation and Management of Patients on Glucocorticoids

Myriad questions regarding perioperative management of patients on glucocorticoids (GCs) continue to be debated including which patients are at risk for adrenal insufficiency (AI), what is the correct dose and duration of supplemental GCs, or are they necessary for everyone? These questions remain partly unanswered due to the heterogeneity and low quality of data, studies with small sample sizes, and the limited number of randomized trials. To date, we know that although all routes of GC administration can result in hypothalamic-pituitary-adrenal (HPA) axis suppression, perioperative adrenal crisis is rare. Correlation between biochemical testing for AI and clinical events is lacking. Some of the current perioperative management recommendations based on daily GC dose and duration of therapy may be difficult to follow in clinical practice. The prospective and retrospective studies consistently report that continuing the daily dose of GCs perioperatively is not associated with a higher risk for adrenal crises in patients with GC-induced AI. Considering that oral GC intake may be unreliable in the early postoperative period, providing the daily GC plus a short course of IV hydrocortisone 25 to 100 mg per day based on the degree of surgical stress seems reasonable. In patients who have stopped GC therapy before surgery, careful assessment of the HPA axis is necessary to avoid an adrenal crisis. In conclusion, our literature review indicates that lower doses and shorter duration of supplemental GCs perioperatively are sufficient to maintain homeostasis. We emphasize the need for well-designed randomized studies on this frequently encountered clinical scenario.

The American Association of Endocrine Surgeons Guidelines for the Definitive Surgical Management of Secondary and Tertiary Renal Hyperparathyroidism

OBJECTIVE

To develop evidence-based recommendations for safe, effective, and appropriate treatment of secondary (SHPT) and tertiary (THPT) renal hyperparathyroidism.

BACKGROUND

Hyperparathyroidism is common among patients with chronic kidney disease, end-stage kidney disease, and kidney transplant. The surgical management of SHPT and THPT is nuanced and requires a multidisciplinary approach. There are currently no clinical practice guidelines that address the surgical treatment of SHPT and THPT.

METHODS

Medical literature was reviewed from January 1, 1985 to present January 1, 2021 by a panel of 10 experts in SHPT and THPT. Recommendations using the best available evidence was constructed. The American College of Physicians grading system was used to determine levels of evidence. Recommendations were discussed to consensus. The American Association of Endocrine Surgeons membership reviewed and commented on preliminary drafts of the content.

RESULTS

These clinical guidelines present the epidemiology and pathophysiology of SHPT and THPT and provide recommendations for work-up and management of SHPT and THPT for all involved clinicians. It outlines the preoperative, intraoperative, and postoperative management of SHPT and THPT, as well as related definitions, operative techniques, morbidity, and outcomes. Specific topics include Pathogenesis and Epidemiology, Initial Evaluation, Imaging, Preoperative and Perioperative Care, Surgical Planning and Parathyroidectomy, Adjuncts and Approaches, Outcomes, and Reoperation.

CONCLUSIONS

Evidence-based guidelines were created to assist clinicians in the optimal management of secondary and tertiary renal hyperparathyroidism.

Systematic review and meta-analysis of risk factors for Mesh infection following Abdominal Wall Hernia Repair Surgery

BACKGROUND

Surgical Mesh Infection (SMI) after Abdominal Wall Hernia Repair (AWHR) represents a catastrophic complication. We performed a systematic review and meta-analysis to analyze the risk factors for SMI in the context of AWHR.

METHODS

PubMed, Embase, Scielo, and LILACS were searched without language or time restrictions from inception until June 2021. Articles evaluating the association between demographic, clinical, laboratory and surgical characteristics with SMI in AWHR were included.

RESULTS

23 studies were evaluated, comprising a total of 118,790 patients (98% males; mean age 56.5 years) with a mesh infection pooled prevalence of 4%. Significant risk factors for SMI were type 2 diabetes mellitus, obesity, smoking history, steroids use, ASA III/IV, laparotomy vs laparoscopy, emergency surgery, duration of surgery and onlay mesh position vs sublay. The quality of evidence was regarded as very low-moderate.

CONCLUSION

Several factors, highlighting sociodemographic characteristics, comorbidities, and the clinical scenario, may increase the risk of developing mesh infections in AWHR. The recognition and mitigation of these may significantly reduce mesh infection rates in this context.

Peri-operative steroid management in the paediatric population

BACKGROUND

Patients with adrenal insufficiency are at risk of adrenal crisis, a potentially life-threatening emergency in the peri-operative period due to their attenuated ability to mount a cortisol response. There is a lack of standardization regarding peri-operative stress-dose glucocorticoids in paediatric clinical practice with the absence of agreed protocols. For the individual patient, the risk of adrenal crisis must be weighed against the potential adverse clinical outcomes associated with unnecessary or supra-physiologic glucocorticoid dosing in susceptible patients. Specific clinical concerns in the paediatric population include osteopenia, growth restriction and increased risk of cardiovascular disease in adulthood. This review aimed to identify and evaluate available literature in the field of peri-operative stress-dose glucocorticoids.

METHODS

A comprehensive literature search was conducted to construct a narrative review.

RESULTS

The outcome of this review identified that paediatric patients, unlike adults, do not show a graded response to surgical stress with implications for glucocorticoid stress dose regimens for general anaesthesia and less invasive surgical procedures. The studies highlight a lack of information on physiological steroid responses to stress situations and differences in the approach to glucocorticoid replacement strategies in the paediatric population.

CONCLUSION

The review identified there is a lack of high-quality paediatric-specific studies evaluating appropriate stress-dose glucocorticoid regimens in paediatric patients with or at risk of adrenal insufficiency. Further research is needed to establish clear evidence-based clinical guidelines for paediatric peri-operative practice regarding steroid stress dosing in adrenal insufficiency. Current knowledge would suggest that a balanced view of risks and benefits should be taken appropriate to the clinical context, to dictate peri-operative stress-dose glucocorticoids use that permits safe perioperative management.

Cortisol in Oral and Maxillofacial Surgery: A Double-Edged Sword

Cortisol is a hormone that is naturally produced by the zona fasciculata of the cortex in the adrenal gland. One of its main functions is to decrease inflammation, particularly in areas where an inflammatory response is not necessary. In the field of oral and maxillofacial surgery, cortisol is used to improve the outcomes of surgical procedures and to make the postoperative period more comfortable for the patient. However, cortisol is considered a double-edged sword because its use is associated with both benefits and adverse effects. It is imperative to use cortisol following an accurate diagnosis, in addition to clarity regarding the desired surgical procedure for treating the acute or chronic condition affecting the patient. When used with caution, cortisol can serve as a valuable agent for reducing the postoperative inflammatory response in patients undergoing moderate as well as moderately severe surgical procedures.

Acute abdomen in the immunocompromised patient: WSES, SIS-E, WSIS, AAST, and GAIS guidelines

Immunocompromised patients are a heterogeneous and diffuse category frequently presenting to the emergency department with acute surgical diseases. Diagnosis and treatment in immunocompromised patients are often complex and must be multidisciplinary. Misdiagnosis of an acute surgical disease may be followed by increased morbidity and mortality. Delayed diagnosis and treatment of surgical disease occur; these patients may seek medical assistance late because their symptoms are often ambiguous. Also, they develop unique surgical problems that do not affect the general population. Management of this population must be multidisciplinary.This paper presents the World Society of Emergency Surgery (WSES), Surgical Infection Society Europe (SIS-E), World Surgical Infection Society (WSIS), American Association for the Surgery of Trauma (AAST), and Global Alliance for Infection in Surgery (GAIS) joined guidelines about the management of acute abdomen in immunocompromised patients.

Perioperative glucocorticoid management based on current evidence

Glucocorticoid preparations, adreno-cortical steroids, with strong anti-inflammatory and immunosuppressive effects, are widely used for treating various diseases. The number of patients exposed to steroid therapy prior to surgery is increasing. When these patients present for surgery, the anesthesiologist must decide whether to administer perioperative steroid supplementation. Stress-dose glucocorticoid administration is required during the perioperative period because of the possibility of failure of cortisol secretion to cope with the increased cortisol requirement due to surgical stress, adrenal insufficiency, hemodynamic instability, and the possibility of adrenal crisis. Therefore, glucocorticoids should be supplemented at the same level as that of normal physiological response to surgical stress by evaluating the invasiveness of surgery and inhibition of the hypothalamus-pituitary-adrenal axis. Various textbooks and research articles recommend the stress-dose of glucocorticoids during perioperative periods. It has been commonly suggested that glucocorticoids should be administered in an amount equivalent to about 100 mg of cortisol for major surgery because it induces approximately 5 times the normal secretion. However, more studies, with appropriate power, regarding the administration of stress-dose glucocorticoids are still required, and evaluation of patients with possible adrenal insufficiency and appropriate glucocorticoid administration based on surgical stress will help improve the prognosis.

Impact of glucocorticoid supplementation on reducing perioperative complications in patients on long-term glucocorticoid medication: A propensity score analysis using a nationwide inpatient database

BACKGROUND

Perioperative glucocorticoid supplementation has been suggested as a potentially effective precaution against perioperative adrenal crisis in patients on long-term glucocorticoid medication.

METHODS

This retrospective cohort study used a national inpatient database in Japan. We included patients who underwent general surgery and those who received long-term glucocorticoid medication before surgery. A one-to-one propensity score-matched analysis was performed to compare patients who received 100 mg hydrocortisone during surgery with those who received no supplementation. The primary outcome was use of vasopressor agents on the day of surgery. The secondary outcomes included bleeding, perioperative infection, wound dehiscence, postoperative length of stay, and in-hospital mortality.

RESULTS

Among the 807 propensity score-matched pairs, there was no significant difference in use of vasopressor agents between patients with and without glucocorticoid supplementation (24.5% vs. 21.9%; P = 0.22) and no significant differences in any secondary outcomes.

CONCLUSIONS

Perioperative glucocorticoid supplementation was not associated with decreased morbidity or mortality.

Perioperative "stress dose" of corticosteroid: Pharmacological and clinical perspective

Various exogenous steroid preparations have been in use for a wide range of indications. We, as an anesthesiologist often encounters a surgical patient receiving chronic steroid therapy. Perioperative use of steroid is associated with major complications such as full-blown adrenal crisis in the perioperative period due to the secondary adrenal insufficiency. Henceforth, comes the role of the perioperative “stress-dose” of steroids to mitigate this rare but potentially fatal complication. There have been opposing views regarding the need and the appropriate dosage of the perioperative steroids. The present review discusses the changing concept of perioperative “stress dose” of corticosteroids, its pharmacokinetics, clinical relevance, and the related controversies such as the need and the appropriate dose.

Perioperative corticosteroid administration: a systematic review and descriptive analysis

Background

Perioperative administration of corticosteroid is common and variable. Guidelines for perioperative corticosteroid administration before non-cardiac non-transplant surgery in patients with current or previous corticosteroid use to reduce the risk of adrenal insufficiency are lacking. Perioperative use of corticosteroid may be associated with serious adverse events, namely hyperglycemia, infection, and poor wound healing.

Objective

To determine whether perioperative administration of corticosteroids, compared to placebo or no intervention, reduces the incidence of adrenal insufficiency in adult patients undergoing non-cardiac surgery who were or are exposed to corticosteroids.

Methods

We searched MEDLINE via Ovid and PubMed, EMBASE via Ovid, and the Cochrane Central Register of Controlled Trials, all from 1995 to January 2017.

Selection criteria

We included randomized controlled trials (RCTs), cohort studies, case-studies, and systematic reviews involving adults undergoing non-cardiac non-transplant surgery and reporting the incidence of postoperative adrenal insufficiency.

Data collection and analysis

Two authors independently assessed studies' quality and extracted data. A descriptive and bias assessment analysis was performed.

Results

Two RCTs (total of 37 patients), five cohort studies (total of 462 patients), and four systematic reviews were included. Neither RCT showed a significant difference in the outcome. This result was like that of the five cohort studies. The quality of the evidence was low.

Conclusion

The current use of perioperative corticosteroid supplementation to prevent adrenal insufficiency is not supported by evidence. Given the significant studies' limitations, it is not possible to conclude that perioperative administration of corticosteroids, compared to placebo, reduces the incidence of adrenal insufficiency.

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.

Stress Dose Steroids: Myths and Perioperative Medicine

Perioperative medication management for patients with systemic autoimmune inflammatory diseases has focused on strategies to improve outcomes and mitigate risks. The emphasis has been to minimize the risk of infection associated with most antirheumatic medications, while attempting to avoid flares of disease precipitated by medication withdrawal. Management of glucocorticoids in the perioperative period has been based on an assumption that supraphysiologic increases in dose were always necessary to avoid hypotension and shock in glucocorticoid treated patients, and alternative strategies were rarely considered despite the known infectious, metabolic, and wound healing risks associated with glucocorticoid administration. This paper will review current recommendations for perioperative glucocorticoid administration for glucocorticoid treated patients with systemic inflammatory autoimmune diseases and discuss glucocorticoid physiology to analyze the basis for these recommendations and consider alternative perioperative management strategies.

Perioperative Steroid Management

Perioperative stress-dose steroid administration remains a controversial topic, with recent studies questioning its necessity. We discuss the current literature, largely published in nonanesthesiology journals, and suggest a practical approach to perioperative steroid management.

Hormonal Replacement in Hypopituitarism in Adults: An Endocrine Society Clinical Practice Guideline

OBJECTIVE

To formulate clinical practice guidelines for hormonal replacement in hypopituitarism in adults.

PARTICIPANTS

The participants include an Endocrine Society-appointed Task Force of six experts, a methodologist, and a medical writer. The American Association for Clinical Chemistry, the Pituitary Society, and the European Society of Endocrinology co-sponsored this guideline.

EVIDENCE

The Task Force developed this evidence-based guideline using the Grading of Recommendations, Assessment, Development, and Evaluation system to describe the strength of recommendations and the quality of evidence. The Task Force commissioned two systematic reviews and used the best available evidence from other published systematic reviews and individual studies.

CONSENSUS PROCESS

One group meeting, several conference calls, and e-mail communications enabled consensus. Committees and members of the Endocrine Society, the American Association for Clinical Chemistry, the Pituitary Society, and the European Society of Endocrinology reviewed and commented on preliminary drafts of these guidelines.

CONCLUSIONS

Using an evidence-based approach, this guideline addresses important clinical issues regarding the evaluation and management of hypopituitarism in adults, including appropriate biochemical assessments, specific therapeutic decisions to decrease the risk of co-morbidities due to hormonal over-replacement or under-replacement, and managing hypopituitarism during pregnancy, pituitary surgery, and other types of surgeries.

Diagnosis and treatment of adrenal insufficiency including adrenal crisis: a Japan Endocrine Society clinical practice guideline [Opinion]

This clinical practice guideline of the diagnosis and treatment of adrenal insufficiency (AI) including adrenal crisis was produced on behalf of the Japan Endocrine Society. This evidence-based guideline was developed by a committee including all authors, and was reviewed by a subcommittee of the Japan Endocrine Society. The Japanese version has already been published, and the essential points have been summarized in this English language version. We recommend diagnostic tests, including measurement of basal cortisol and ACTH levels in combination with a rapid ACTH (250 μg corticotropin) test, the CRH test, and for particular situations the insulin tolerance test. Cut-off values in basal and peak cortisol levels after the rapid ACTH or CRH tests are proposed based on the assumption that a peak cortisol level ≥18 μg/dL in the insulin tolerance test indicates normal adrenal function. In adult AI patients, 15-25 mg hydrocortisone (HC) in 2-3 daily doses, depending on adrenal reserve and body weight, is a basic replacement regime for AI. In special situations such as sickness, operations, pregnancy and drug interactions, cautious HC dosing or the correct choice of glucocorticoids is necessary. From long-term treatment, optimal diurnal rhythm and concentration of serum cortisol are important for the prevention of cardiovascular disease and osteoporosis. In maintenance therapy during the growth period of patients with 21-hydroxylase deficiency, proper doses of HC should be used, and long-acting glucocorticoids should not be used. Education and carrying an emergency card are essential for the prevention and rapid treatment of adrenal crisis.

Abdominal Wound Dehiscence in Patients Receiving Long-term Steroid Treatment

Steroids inhibit primary wound healing and delay the formation of granulation tissue, but it has been controversial whether long-term steroid treatment by itself increases the risk of abdominal wound dehiscence. The aim of this study was to determine whether the pre-operative dose and post-operative total dose of steroids influence abdominal wound dehiscence. Of 28 patients who had surgery while receiving long-term steroid treatment, seven had abdominal wound dehiscence and 21 did not have dehiscence. The two groups differed significantly in the post-operative dose of steroids (404.3 ± 147.1 and 135.6 ± 118.7 mg, respectively) and the duration of wound healing (57.3 ± 18.0 and 12.4 ± 3.8 days), but no other differences were found. Abdominal wound dehiscence may be influenced by the post-operative rather than the pre-operative steroid dose.

Diagnosis and Treatment of Primary Adrenal Insufficiency: An Endocrine Society Clinical Practice Guideline

OBJECTIVE

This clinical practice guideline addresses the diagnosis and treatment of primary adrenal insufficiency.

PARTICIPANTS

The Task Force included a chair, selected by The Clinical Guidelines Subcommittee of the Endocrine Society, eight additional clinicians experienced with the disease, a methodologist, and a medical writer. The co-sponsoring associations (European Society of Endocrinology and the American Association for Clinical Chemistry) had participating members. The Task Force received no corporate funding or remuneration in connection with this review.

EVIDENCE

This evidence-based guideline was developed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system to determine the strength of recommendations and the quality of evidence.

CONSENSUS PROCESS

The evidence used to formulate recommendations was derived from two commissioned systematic reviews as well as other published systematic reviews and studies identified by the Task Force. The guideline was reviewed and approved sequentially by the Endocrine Society's Clinical Guidelines Subcommittee and Clinical Affairs Core Committee, members responding to a web posting, and the Endocrine Society Council. At each stage, the Task Force incorporated changes in response to written comments.

CONCLUSIONS

We recommend diagnostic tests for the exclusion of primary adrenal insufficiency in all patients with indicative clinical symptoms or signs. In particular, we suggest a low diagnostic (and therapeutic) threshold in acutely ill patients, as well as in patients with predisposing factors. This is also recommended for pregnant women with unexplained persistent nausea, fatigue, and hypotension. We recommend a short corticotropin test (250 μg) as the "gold standard" diagnostic tool to establish the diagnosis. If a short corticotropin test is not possible in the first instance, we recommend an initial screening procedure comprising the measurement of morning plasma ACTH and cortisol levels. Diagnosis of the underlying cause should include a validated assay of autoantibodies against 21-hydroxylase. In autoantibody-negative individuals, other causes should be sought. We recommend once-daily fludrocortisone (median, 0.1 mg) and hydrocortisone (15-25 mg/d) or cortisone acetate replacement (20-35 mg/d) applied in two to three daily doses in adults. In children, hydrocortisone (∼8 mg/m(2)/d) is recommended. Patients should be educated about stress dosing and equipped with a steroid card and glucocorticoid preparation for parenteral emergency administration. Follow-up should aim at monitoring appropriate dosing of corticosteroids and associated autoimmune diseases, particularly autoimmune thyroid disease.

Perioperative corticosteroid management for patients with inflammatory bowel disease

Guidelines on the appropriate use of perioperative steroids in patients with inflammatory bowel disease (IBD) are lacking. As a result, corticosteroid supplementation during and after colorectal surgery procedures has been shown to be highly variable. A clearer understanding of the indications for perioperative corticosteroid administration relative to preoperative corticosteroid dosing and duration of therapy is essential. In this review, we outline the basic tenets of the hypothalamic-pituitary-adrenal (HPA) axis and its normal response to stress, describe how corticosteroid use is thought to affect this system, and provide an overview of the currently available data on perioperative corticosteroid supplementation including the limited evidence pertaining to patients with inflammatory bowel disease. Based on currently existing data, we define "adrenal suppression," and propose a patient-based approach to perioperative corticosteroid management in the inflammatory bowel disease population based on an individual's historical use of corticosteroids, the type of surgery they are undergoing, and HPA axis testing when applicable. Patients without adrenal suppression (<5 mg prednisone per day) do not require extra corticosteroid supplementation in the perioperative period; patients with adrenal suppression (>20 mg prednisone per day) should be treated with additional perioperative corticosteroid coverage above their baseline home regimen; and patients with unclear HPA axis function (>5 and <20 mg prednisone per day) should undergo preoperative HPA axis testing to determine the best management practices. The proposed management algorithm attempts to balance the risks of adrenal insufficiency and immunosuppression.

Perioperative stress-dose steroids

Supraphysiologic corticosteroid doses have routinely been considered the perioperative standard of care over the past six decades for patients on long-term steroid therapy. However, the accumulation of data over this period is beginning to suggest that such a practice may not be necessary. The majority of these studies are retrospective reviews or small prospective cohorts, but there are two small prospective, randomized placebo-controlled trials, one prospective primate trial, and several systematic reviews addressing the issue. Based on this developing evidence, patients on long-term exogenous steroids do not require high-dose perioperative corticosteroids and should instead remain on their baseline maintenance dose, with the understanding that secondary adrenal insufficiency should be considered for unexplained perioperative hypotension in these patients.

Adrenocortical function in hypotensive patients with end stage renal disease

BACKGROUND

Sustained hypotension among patients with end stage renal disease on dialysis (ESRDh) varies from 5.0% to 12.0%. Despite their role in the regulation of blood pressure (BP) corticoadrenal hormones have been poorly investigated.

OBJECTIVES

This study aims to detect adrenal insufficiency in ESRDh and follow their clinical outcome.

METHODS

Fifty ESRDh and 30 healthy volunteers were studied. In all cases basal blood and saliva were obtained. Synthetic ACTH (25μg) was injected intramuscularly and at 30min saliva was collected. Circulating ACTH, renin, cortisol and aldosterone were measured and steroids were also assessed in saliva by immunoassay.

RESULTS

Fifteen ESRDh achieved steroid responses not different than healthy volunteers; four had primary adrenal insufficiency; six had secondary adrenal insufficiency; nine had selective hypoaldosteronism and sixteen secondary hyperaldosteronism. The years on dialysis did not differ among subgroups. ROC analysis defined the following cut-offs for basal cortisol to predict adrenal insufficiency: in serum ⩽232.0nM (sensitivity (S) 100.0% and specificity (E) 90.0%); in saliva ⩽4.4nM (100.0% S and E). Basal aldosterone cut-off values to predict hyperaldosteronism were: in serum >500.0pM and saliva >60.0pM (100.0% S and E, for both). For the prediction of hypoaldosteronism the basal serum aldosterone was ⩽260.0pM (100% S; 53% E) and in saliva it was ⩽20.1pM (100% S; 58.5% E). Three patients with primary adrenal insufficiency and six with secondary adrenal insufficiency improved general clinical condition and normalized BP on steroids. One patient died before initiation of steroid therapy.

CONCLUSION

Adrenal function should be assessed in ESRDh in order to unmask adrenal insufficient states.

Perioperative infection in the patient with rheumatic disease

The risk of infection accompanies the benefits of surgery. Immunomodulatory chronic illnesses may increase the risk of surgical infections. Surgical patients with rheumatologic illness need close preoperative assessment regarding their infection risks (fixed and modifiable), which vary on the basis of the proposed procedure, specific rheumatologic illness, and underlying comorbidities. Modification of the medication regimens in the preoperative period may decrease risk and enhance healing. Intraoperative antisepsis and antibiotic prophylaxis remain critical in this patient population. Postoperative fevers within 3 days of surgery are usually noninfectious but require vigilance and attention. The principles of surgical infection reduction are not different in the rheumatologic and general patient populations, but best practice depends on expertise in caring for patients with these illnesses.

Common medical illnesses that affect anesthesia and their anesthetic management

Patients undergoing an office-based anesthetic require a thorough preoperative evaluation to identify medical illnesses and undertake appropriate investigations or studies. This article addresses common medical illnesses seen in oral surgery offices and provides insight into their anesthetic management, concentrating on open-airway office-based anesthesia.

[How to manage the interruption of a treatment with anti-inflammatory corticosteroids?]

A prolonged treatment with anti-inflammatory corticosteroids induces an inhibition of ACTH secretion from pituitary corticotroph cells. An abrupt interruption of such a treatment potentially leads to the risk of an acute adrenal failure, in particular in stressing situations. The inertia in reactivation of the secretion of the stimulating hypothalamic factors (CRH and AVP) and consecutively of ACTH can be responsible for an inability to adapt the secretion of glucocorticoids in response to stress. A short-time treatment (<3 weeks) with anti-inflammatory corticoids does not expose to this risk. On the contrary, a more prolonged treatment, especially with high daily doses, needs to perform an evaluation of the level of corticotroph secretion. This evaluation should be done before to consider that either stopping the treatment is out of risk or if the initiation of a substitutive treatment with hydrocortisone is required. The measurement of morning plasma cortisol level already provides a significant information. As to whether that is needed, a dynamic evaluation can be performed. Among the available tests, the Synacthen(®)test, easy to perform and using at best 1μg of β1-24 ACTH, appears the most finely informative to answer this question and to choose the most adapted follow-up.

Impact of stress dose steroids on the outcomes of restorative proctocolectomy in patients with ulcerative colitis

BACKGROUND

Stress dose steroids are administered during the perioperative period to prevent complications of secondary hypoadrenalism, which can occur after long-term steroid treatment. Steroids also increase postoperative morbidity. Patients with ulcerative colitis often require steroid therapy before definitive surgery and often receive perioperative steroids in a variety of doses.

OBJECTIVE

The aim of this study was to evaluate the impact of stress dose steroid administration on short-term postoperative outcomes after restorative proctocolectomy in patients with ulcerative colitis.

DESIGN

This was a retrospective cohort study.

SETTING

The investigation took place in a high-volume, specialized colorectal surgery department.

PATIENTS

Patients who had been treated with steroids for ulcerative colitis and underwent a restorative proctocolectomy from January 2009 to July 2011 were identified and categorized into 2 groups based on whether they received stress dose steroids.

MAIN OUTCOME MEASURES

Both cohorts were compared for patient demographics, duration of steroid treatment before surgery, and operative and postoperative outcomes.

RESULTS

Eighty-nine patients received stress dose steroids and 146 patients did not. Stress dose steroids were more frequently administered to patients who were under steroid treatment immediately before restorative proctocolectomy (37.1% versus 10.3%; p < 0.001). A sinus tachycardia developed more frequently in patients who received stress dose steroids during surgery (p = 0.03). One patient in the stress dose steroid group died on postoperative day 25 because of anastomotic leak. Although no patients in either group had an adrenal crisis during surgery, 1 patient in the stress dose steroid group was diagnosed with adrenal insufficiency postoperatively.

LIMITATIONS

This study was limited by its retrospective and nonrandomized nature.

CONCLUSIONS

Although administration of stress dose steroids is not related to increased postoperative complications, the steroids do not appear to affect adrenal insufficiency outcomes. Patients who were treated with steroids for ulcerative colitis should be monitored carefully in the perioperative and early postoperative periods for signs of adrenal insufficiency, regardless of the steroid regimen used.

Selective use of peri-operative steroids in pituitary tumor surgery: escape from dogma

OBJECTIVE

Traditional neurosurgical practice calls for administration of peri-operative stress-dose steroids for sellar-suprasellar masses undergoing operative treatment. This practice is considered critical to prevent peri-operative complications associated with hypoadrenalism, such as hypotension and circulatory collapse. However, stress-dose steroids complicate the management of these patients. It has been our routine practice to use stress steroids during surgery only if the patient has clinical or biochemical evidence of hypocortisolism pre-operatively. We wanted to be certain that this practice was safe.

METHODS

We present our retrospective analysis from a consecutive series of 114 operations in 109 patients with sellar and/or suprasellar tumors, the majority of whom were managed without empirical stress-dose steroid coverage. Only patients who were hypoadrenal pre-operatively or who had suffered apoplexy were given stress-dose coverage during surgery. We screened for biochemical evidence of hypoadrenalism as a result of surgery by measuring immediate post-operative AM serum cortisol levels.

RESULTS

There were no adverse events related to the selective use of cortisol replacement in this patient population.

CONCLUSION

Our experience demonstrates that selective use of corticosteroid replacement is safe; it simplifies the management of the patients, and has advantages over empiric "dogmatic" steroid coverage.

Supplemental perioperative steroids for surgical patients with adrenal insufficiency

BACKGROUND

Adrenal crisis is a life threatening condition which can be induced by stress during surgery in patients with adrenal insufficiency. This may be prevented by perioperative administration of high doses of steroids. There is disagreement on whether supplemental perioperative steroids are required and, when administered, on the amount and frequency of doses. The review was originally published in 2009 and was updated in 2012.

OBJECTIVES

To assess whether it is necessary to administer supplemental perioperative steroids in adult patients on maintenance doses of glucocorticoids because of adrenal insufficiency.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 2); MEDLINE (1966 to February 2012); EMBASE (1980 to February 2012); LILACS (1982 to May 2012); and the databases of ongoing trials. We handsearched the Journal of Clinical Endocrinology and Metabolism (1982 to 2008), Clinical Endocrinology (1972 to 2008), Surgery (1948 to 1994), Annals of Surgery (1948 to 1994), and Anaesthesia (1948 to 2001). The original search was performed in January 2009.

SELECTION CRITERIA

We included randomized controlled trials that compared the use of supplemental perioperative steroids to placebo in adult patients on maintenance doses of steroids and who required surgery.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trial quality and extracted data. Study authors were contacted for missing information. We used mean differences and standard deviations to summarize the data for each group.

MAIN RESULTS

Two trials involving 37 patients were included. These studies reported that supplemental perioperative steroids were not required during surgery for patients with adrenal insufficiency. Neither study reported any adverse effects or complications in the intervention and control groups. Both studies were graded as having a high risk of bias.

AUTHORS' CONCLUSIONS

Owing to the small number of patients, the results may not be representative. Based on current available evidence, we are unable to support or refute the use of supplemental perioperative steroids for patients with adrenal insufficiency during surgery.

Transphenoidal surgery without steroid replacement in patients with morning serum cortisol below 9 μg/dl (250 Nmol/l)

BACKGROUND

Adrenal insufficiency is a feared complication in patients undergoing transphenoidal surgery (TSS). Using the insulin tolerance test (ITT) for the preoperative assessment of hypothalamic-pituitary-adrenal (HPA) status is less than ideal, and the morning serum cortisol (MSC) is often used as a proxy for ITT. However, neither the ITT nor the MSC level has been validated to indicate HPA sufficiency compared to a physiological gold standard such as patients' ability to withstand transphenoidal surgery.

OBJECTIVE

To evaluate the intraoperative and postoperative course of nine patients with non-ACTH-secreting pituitary adenomas who did not receive intraoperative cortisol replacement despite having a preoperative MSC below 9 μg/dl (250 nmol/l) and to compare this with a set of patients with a preoperative MSC greater than 14.5 μg/dl (400 nmol/l) and another set of patients with MSC below 9 μg/dl (250 nmol/l) who received intraoperative cortisol administration.

METHODS

Preoperative and day 1 and day 2 postoperative MSC, intraoperative anesthetic record, vital signs, fluid balance, medications, and complications were recorded.

RESULTS

None of the patients experienced the full syndrome of adrenal insufficiency. One patient with a preoperative MSC <9 μg/dl (250 mol/l) had isolated postoperative fatigue and required cortisol replacement. No patient suffered any life-threatening complications. There were no differences among the three groups in their intraoperative or postoperative courses when compared for intraoperative hypotension, acute blood pressure drop, and administration of vasopressors.

CONCLUSION

This study suggests that TSS can be performed safely in patients with preoperative MSC less than 9 μg/dl (250 nmol/l) in closely monitored settings without intraoperative cortisol administration. Further studies are warranted.

Inflammatory bowel disease: perioperative pharmacological considerations

The perioperative management of patients with inflammatory bowel disease is challenging given the altered immune system that results from a variety of biologic and immunomodulator therapies. Clinicians are often faced with challenges and complicated equations when deciding on the type and dose of medication. To understand the effect of these medications and review the evidence regarding the management of these medications in the perioperative setting, a PubMed-based literature search (January 1, 1960, through April 1, 2011) was conducted using the following search terms: perioperative management, risk, outcome, inflammatory bowel disease, ulcerative colitis, Crohn's disease, aminosalicylates, glucocorticoids, purine analogues, cyclosporine, methotrexate, biologic therapy, infliximab, and thromboembolism. The 414 articles identified were manually sorted to exclude those that did not address perioperative risk, outcomes, and medications in the abstracts, yielding 84 articles for review. Additional references were obtained from the citations within the retrieved articles. This review surveys the findings of the selected articles and presents guidelines and resources for perioperative medication management for patients with inflammatory bowel disease undergoing surgery.

Methylprednisolone reduces postoperative nausea in total knee and hip arthroplasty

WHAT IS KNOWN AND OBJECTIVE

Total knee and hip joint replacement has a high risk of postoperative nausea and vomiting (PONV), and steroid cover is used for cases associated with autoimmune diseases. Our aim is to evaluate the antiemetic efficacy of methylprednisolone as steroid cover in patients undergoing the surgery.

METHODS

A prospective cohort study design was used. Sixty-eight patients, aged between 20 and 80 years, were scheduled for a standardized general anaesthetic technique. Patients who were given methylprednisolone were assigned as the steroid cover group, and those who were not given methylprednisolone formed the non-steroid cover group. PONV were assessment by direct questioning or spontaneous complaints by patients 1 week after surgery. Postoperative pain was evaluated using Visual Analog Scale (VAS) 1 and 3 days after surgery.

RESULTS AND DISCUSSION

The incidence of nausea in the steroid cover group was significantly less than that in the non-steroid cover group (adjusted odds ratio, 0·17, P = 0·021), but there was no significant difference in vomiting between the two groups. Postoperative pain VAS score was not significantly different between groups.

WHAT IS NEW AND CONCLUSION

In total knee and hip arthroplasty, methylprednisolone is effective in preventing postoperative nausea; however, higher doses of methylprednisolone may be needed to prevent vomiting.

Perioperative management of patients with connective tissue disease

Diseases of the connective tissue are a varied group of disorders with major musculoskeletal manifestations such as joint pain and loss of function. As a consequence of the accompanying inflammatory joint disease, such patients often require surgery. Due to the protean organ-related consequences of these conditions, patients who suffer from chronic connective tissue disease are a highly challenging population in the perioperative context. This paper reviews the management of such patients in this clinical setting.
