What's new in childhood tuberculosis.

PURPOSE OF REVIEW: The current review identifies recent advances in the prevention, diagnosis, and treatment of childhood tuberculosis (TB) with a focus on the WHO's updated TB management guidelines released in 2022. RECENT FINDINGS: The COVID-19 pandemic negatively affected global TB control due to the diversion of healthcare resources and decreased patient care-seeking behaviour. Despite this, key advances in childhood TB management have continued. The WHO now recommends shorter rifamycin-based regimens for TB preventive treatment as well as shorter regimens for the treatment of both drug-susceptible and drug-resistant TB. The Xpert Ultra assay is now recommended as the initial diagnostic test for TB in children with presumed TB and can also be used on stool samples. Point-of-care urinary lipoarabinomannan assays are promising as 'rule-in' tests for children with presumed TB living with HIV. Treatment decision algorithms can be used to diagnose TB in symptomatic children in settings with and without access to chest X-rays; bacteriological confirmation should always be attempted. SUMMARY: Recent guideline updates are a key milestone in the management of childhood TB, and the paediatric TB community should now prioritize their efficient implementation in high TB burden countries while generating evidence to close current evidence gaps.

Balancing selection at a premature stop mutation in the myostatin gene underlies a recessive leg weakness syndrome in pigs.

Balancing selection provides a plausible explanation for the maintenance of deleterious alleles at moderate frequency in livestock, including lethal recessives exhibiting heterozygous advantage in carriers. In the current study, a leg weakness syndrome causing mortality of piglets in a commercial line showed monogenic recessive inheritance, and a region on chromosome 15 associated with the syndrome was identified by homozygosity mapping. Whole genome resequencing of cases and controls identified a mutation causing a premature stop codon within exon 3 of the porcine Myostatin (MSTN) gene, similar to those causing a double-muscling phenotype observed in several mammalian species. The MSTN mutation was in Hardy-Weinberg equilibrium in the population at birth, but significantly distorted amongst animals still in the herd at 110 kg, due to an absence of homozygous mutant genotypes. In heterozygous form, the MSTN mutation was associated with a major increase in muscle depth and decrease in fat depth, suggesting that the deleterious allele was maintained at moderate frequency due to heterozygous advantage (allele frequency, q = 0.22). Knockout of the porcine MSTN by gene editing has previously been linked to problems of low piglet survival and lameness. This MSTN mutation is an example of putative balancing selection in livestock, providing a plausible explanation for the lack of disrupting MSTN mutations in pigs despite many generations of selection for lean growth.

2022 American College of Rheumatology/American Association of Hip and Knee Surgeons Guideline for the Perioperative Management of Antirheumatic Medication in Patients With Rheumatic Diseases Undergoing Elective Total Hip or Total Knee Arthroplasty.

OBJECTIVE: To develop updated American College of Rheumatology/American Association of Hip and Knee Surgeons guidelines for the perioperative management of disease-modifying medications for patients with rheumatic diseases, specifically those with inflammatory arthritis (IA) and those with systemic lupus erythematosus (SLE), undergoing elective total hip arthroplasty (THA) or elective total knee arthroplasty (TKA). METHODS: We convened a panel of rheumatologists, orthopedic surgeons, and infectious disease specialists, updated the systematic literature review, and included currently available medications for the clinically relevant population, intervention, comparator, and outcomes (PICO) questions. We used the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology to rate the quality of evidence and the strength of recommendations using a group consensus process. RESULTS: This guideline updates the 2017 recommendations for perioperative use of disease-modifying antirheumatic therapy, including traditional disease-modifying antirheumatic drugs, biologic agents, targeted synthetic small-molecule drugs, and glucocorticoids used for adults with rheumatic diseases, specifically for the treatment of patients with IA, including rheumatoid arthritis and spondyloarthritis, those with juvenile idiopathic arthritis, or those with SLE who are undergoing elective THA or TKA. It updates recommendations regarding when to continue, when to withhold, and when to restart these medications and the optimal perioperative dosing of glucocorticoids. CONCLUSION: This updated guideline includes recently introduced immunosuppressive medications to help decision-making by clinicians and patients regarding perioperative disease-modifying medication management for patients with IA and SLE at the time of elective THA or TKA.

Is There an Association Between Ulnar Nerve Hypermobility and Neuropathy at the Elbow?

OBJECTIVE: To systematically review the association between ulnar nerve hypermobility (UNH) at the elbow and ulnar neuropathy (UNE). DATA SOURCES: Cumulative Index to Nursing and Allied Health, MEDLINE, and Embase databases were searched for English language studies published up to July 4, 2020. STUDY SELECTION: We included case-control, cohort, and randomized controlled studies that established the presence or absence of UNH and UNE. Twenty out of 654 studies identified met the inclusion criteria. DATA EXTRACTION: Two reviewers independently extracted data for analysis. Risk of bias and applicability were assessed with the QUADAS-2 tool. DATA SYNTHESIS: We compared rates of UNH between patients diagnosed with and without UNE and found no significant difference. The meta-analysis pooled rate of UNH was 0.37 (95% confidence interval, 0.20-0.57) for those without UNE and 0.33 (95% confidence interval, 0.23-0.45) for those with UNE. CONCLUSIONS: The clinical finding of UNH is unhelpful when assessing for UNE, as the presence of UNH does not make the diagnosis of UNE more likely.

Atrial Fibrillation in Indigenous Australians: A Multisite Screening Study Using a Single-Lead ECG Device in Aboriginal Primary Health Settings.

BACKGROUND: Circulatory diseases continue to be the greatest cause of mortality for Australian Aboriginal and Torres Strait Islander people, and a major cause of persistently lower life expectancy compared with non-Aboriginal Australians. The limited information that exists on atrial fibrillation (AF) prevalence in Aboriginal and Torres Strait Islander communities is mostly based on hospital admission data. This shows AF as principal or additional admission diagnosis was 1.4 times higher compared to non-Aboriginal Australians, a higher incidence of AF across the adult life span after age 20 years and a significantly higher prevalence among younger patients. Our study estimates the first national community prevalence and age distribution of AF (including paroxysmal) in Australian Aboriginal people. A handheld single-lead electrocardiograph (ECG) device (iECG), known to be acceptable in this population, was used to record participant ECGs. METHODS: This co-designed, descriptive cross-sectional study was conducted in partnership with 16 Aboriginal Community Controlled Health organisations at their facilities and/or with their services delivered elsewhere. The study was also conducted at one state community event. Three (3) Australian jurisdictions were involved: New South Wales, Western Australia and the Northern Territory. Study sites were located in remote, regional and urban areas. Opportunistic recruitment occurred between June 2016 and December 2017. People <45 years of age were excluded. RESULTS: Thirty (30) of 619 Aboriginal people received a 'Possible AF' and 81 an 'Unclassified' result from a hand-held smartphone ECG device. A final diagnosis of AF was made in 29 participants (4.7%; 95%CI 3.0-6.4%), 25 with known AF (five paroxysmal), and four with previously unknown AF. Three (3) of the four with unknown AF were aged between 55-64 years, consistent with a younger age of AF onset in Aboriginal people. Estimated AF prevalence increased with age and was higher in those aged >55 years than the general population (7.2% compared with 5.4%). Slightly more men than women were diagnosed with AF. CONCLUSIONS: This study is a significant contribution to the evidence which supports screening for AF in Aboriginal and Torres Strait Islander people commencing at a younger age than as recommended in the Australian guidelines (>65 years). We recommend the age of 55 years. Consideration should be given to the inclusion of AF screening in the Australian Government Department of Health annual 'Aboriginal and Torres Strait Islander Health Assessment'. CLINICAL TRIAL REGISTRATION: ACTRN12616000459426.

Clinical and Cardiac Safety of Long-term Levofloxacin in Children Treated for Multidrug-resistant Tuberculosis.

Safety concerns persist for long-term pediatric fluoroquinolone use. Seventy children (median age, 2.1 years) treated with levofloxacin 10-20 mg/kg once daily for multidrug-resistant tuberculosis (median observation time, 11.8 months) had few musculoskeletal events, no levofloxacin-attributed serious adverse events, and no Fridericia-corrected QT interval >450 ms. Long-term levofloxacin was safe and well tolerated.

A Delphi-Based Consensus Statement on the Management of Anticoagulated Patients With Botulinum Toxin for Limb Spasticity.

OBJECTIVE: To create a consensus statement on the considerations for treatment of anticoagulated patients with botulinum toxin A (BoNTA) intramuscular injections for limb spasticity. DESIGN: We used the Delphi method. SETTING: A multiquestion electronic survey. PARTICIPANTS: Canadian physicians (N=39) who use BoNTA injections for spasticity management in their practice. INTERVENTIONS: After the survey was sent, there were e-mail discussions to facilitate an understanding of the issues underlying the responses. Consensus for each question was reached when agreement level was ≥75%. MAIN OUTCOME MEASURES: Not applicable. RESULTS: When injecting BoNTA in anticoagulated patients: (1) BoNTA injections should not be withheld regardless of muscles injected; (2) a 25G or smaller size needle should be used when injecting into the deep leg compartment muscles; (3) international normalized ratio (INR) level should be ≤3.5 when injecting the deep leg compartment muscles; (4) if there are clinical concerns such as history of a fluctuating INR, recent bleeding, excessive or new bruising, then an INR value on the day of injection with point-of-care testing or within the preceding 2-3 days should be taken into consideration when injecting deep compartment muscles; (5) the concern regarding bleeding when using direct oral anticoagulants (DOACs) should be the same as with warfarin (when INR is in the therapeutic range); (6) the dose and scheduling of DOACs should not be altered for the purpose of minimizing the risk of bleeding prior to BoNTA injections. CONCLUSIONS: These consensus statements provide a framework for physicians to consider when injecting BoNTA for spasticity in anticoagulated patients. These consensus statements are not strict guidelines or decision-making steps, but rather an effort to generate common understanding in the absence of evidence in the literature.

Does the method of botulinum neurotoxin injection for limb spasticity affect outcomes? A systematic review.

OBJECTIVE: To systematically review randomized controlled trials of botulinum neurotoxin for limb spasticity to determine whether different injection techniques affect spasticity outcomes. METHODS: MEDLINE, EMBASE, CINAHL, and Cochrane Central Register of Controlled Trials electronic databases were searched for English language human randomized controlled trials from 1990 to 13 May 2016. Studies were assessed in duplicate for data extraction and risk of bias using the Physiotherapy Evidence Database scale and graded according to Sackett's levels of evidence. RESULTS: Nine of 347 studies screened met selection criteria. Four categories of botulinum neurotoxin injection techniques were identified: (1) injection localization technique; (2) injection site selection; (3) injectate volume; (4) injection volume and site selection. There is level 1 evidence that: ultrasound, electromyography, and electrostimulation are superior to manual needle placement; endplate injections improve outcomes vs. multisite quadrant injections; motor point injections are equivalent to multisite injections; high volume injections are similar to low volume injections; and high volume injections distant from the endplate are more efficacious than low volumes closer to the endplate. CONCLUSION: Level 1 evidence exists for differences in treatment outcomes using specific botulinum neurotoxin injection techniques. Findings are based on single studies that require independent replication and further study.

A randomized controlled trial to evaluate the feasibility of the Wii Fit for improving walking in older adults with lower limb amputation.

OBJECTIVE: To assess the feasibility of Wii.n.Walk for improving walking capacity in older adults with lower limb amputation. DESIGN: A parallel, evaluator-blind randomized controlled feasibility trial. SETTING: Community-living. PARTICIPANTS: Individuals who were ⩾50 years old with a unilateral lower limb amputation. INTERVENTION: Wii.n.Walk consisted of Wii Fit training, 3x/week (40 minute sessions), for 4 weeks. Training started in the clinic in groups of 3 and graduated to unsupervised home training. Control group were trained using cognitive games. MAIN MEASURES: Feasibility indicators: trial process (recruitment, retention, participants' perceived benefit from the Wii.n.Walk intervention measured by exit questionnaire), resources (adherence), management (participant processing, blinding), and treatment (adverse event, and Cohen's d effect size and variance). Primary clinical outcome: walking capacity measured using the 2 Minute Walk Test at baseline, end of treatment, and 3-week retention. RESULTS: Of 28 randomized participants, 24 completed the trial (12/arm). Median (range) age was 62.0 (50-78) years. Mean (SD) score for perceived benefit from the Wii.n.Walk intervention was 38.9/45 (6.8). Adherence was 83.4%. The effect sizes for the 2 Minute Walk Test were 0.5 (end of treatment) and 0.6 (3-week retention) based on intention to treat with imputed data; and 0.9 (end of treatment) and 1.2 (3-week retention) based on per protocol analysis. The required sample size for a future larger RCT was deemed to be 72 (36 per arm). CONCLUSIONS: The results suggested the feasibility of the Wii.n.Walk with a medium effect size for improving walking capacity. Future larger randomized controlled trials investigating efficacy are warranted.

Systematic review of adjunct therapies to improve outcomes following botulinum toxin injection for treatment of limb spasticity.

OBJECTIVE: To determine the quality of evidence from randomized controlled trials on the efficacy of adjunct therapies following botulinum toxin injections for limb spasticity. DATA SOURCES: MEDLINE, EMBASE, CINAHL, and Cochrane Central Register of Controlled Trials electronic databases were searched for English language human studies from 1980 to 21 May 2015. STUDY SELECTION: Randomized controlled trials assessing adjunct therapies postbotulinum toxin injection for treatment of spasticity were included. Of the 268 studies screened, 17 met selection criteria. DATA EXTRACTION: Two reviewers independently assessed risk of bias using the Physiotherapy Evidence Database (PEDro) scale and graded according to Sackett's levels of evidence. DATA SYNTHESIS: Ten adjunct therapies were identified. Evidence suggests that adjunct use of electrical stimulation, modified constraint-induced movement therapy, physiotherapy (all Level 1), casting and dynamic splinting (both Level 2) result in improved Modified Ashworth Scale scores by at least 1 grade. There is Level 1 and 2 evidence that adjunct taping, segmental muscle vibration, cyclic functional electrical stimulation, and motorized arm ergometer may not improve outcomes compared with botulinum toxin injections alone. There is Level 1 evidence that casting is better than taping, taping is better than electrical stimulation and stretching, and extracorporeal shock wave therapy is better than electrical stimulation for outcomes including the Modified Ashworth Scale, range of motion and gait. All results are based on single studies. CONCLUSION: There is high level evidence to suggest that adjunct therapies may improve outcomes following botulinum toxin injection. No results have been confirmed by independent replication. All interventions would benefit from further study.

Increased risk for and mortality from invasive pneumococcal disease in HIV-exposed but uninfected infants aged <1 year in South Africa, 2009-2013.

BACKGROUND: High antenatal human immunodeficiency virus (HIV) seroprevalence rates (∼ 30%) with low perinatal HIV transmission rates (2.5%), due to HIV prevention of mother-to-child transmission program improvements in South Africa, has resulted in increasing numbers of HIV-exposed but uninfected (HEU) children. We aimed to describe the epidemiology of invasive pneumococcal disease (IPD) in HEU infants. METHODS: We conducted a cross-sectional study of infants aged <1 year with IPD enrolled in a national, laboratory-based surveillance program for incidence estimations. Incidence was reported for 2 time points, 2009 and 2013. At enhanced sites we collected additional data including HIV status and in-hospital outcome. RESULTS: We identified 2099 IPD cases in infants from 2009 to 2013 from all sites. In infants from enhanced sites (n = 1015), 92% had known HIV exposure status and 86% had known outcomes. IPD incidence was highest in HIV-infected infants, ranging from 272 to 654 per 100,000 population between time points (2013 and 2009), followed by HEU (33-88 per 100,000) and HIV-unexposed and uninfected (HUU) infants (18-28 per 100,000). The case-fatality rate in HEU infants (29% [74/253]) was intermediate between HUU (25% [94/377]) and HIV-infected infants (34% [81/242]). When restricted to infants <6 months of age, HEU infants (37% [59/175]) were at significantly higher risk of dying than HUU infants (32% [51/228]; adjusted relative risk ratio, 1.76 [95% confidence interval, 1.09-2.85]). DISCUSSION: HEU infants are at increased risk of IPD and mortality from IPD compared with HUU children, especially as young infants. HEU infants, whose numbers will likely continue to increase, should be prioritized for interventions such as pneumococcal vaccination along with HIV-infected infants and children.

Canadian Physicians' Use of Ultrasound in Spasticity Treatment: A National Cross-Sectional Survey.

Objective: To identify potential barriers and obstacles preventing clinicians from adopting ultrasound for spasticity management. Design: A prospective, cross-sectional national survey. Setting: Web-based platform. Participants: Thirty-six physicians and surgeons from across Canada. Interventions: Survey completion. Main Outcome Measures: The use of ultrasound in clinical spasticity practice, perceived barriers, and risks associated with its implementation. Results: In total, 36 Canadian physicians and surgeons responded. A total of 91% reported using the US in their practice. Nearly all of them used ultrasonography (US) to guide injections and reported using more than 1 guidance technique for their injections. Less than half of the survey respondents reported using the US for muscle architecture assessment or longitudinal evaluation of muscle echo intensity. A total of 47% of survey respondents reported that they believe there are disadvantages associated with US use in spasticity practice. Disadvantages included increased time requirements resulting in discomfort for the injector and patient, the risk of infection after the procedure, and the risk of needle-stick injury. The most important barrier identified was the increased time demands of US compared with other guidance techniques. Other barriers included a lack of feedback on identifying a spastic muscle compared with electrical guidance techniques, a lack of additional remuneration to complete injections under ultrasound guidance, and a lack of adequate training. Conclusions: Future educational efforts should address clinicians' lack of familiarity with US purposes outside of injection guidance. This survey has highlighted the need for a curriculum shift in spasticity education to improve physician's scanning and injection technique, to address concerns about increased time requirements for injecting under ultrasound guidance and to address perceived disadvantages from clinicians.

Preventive therapy for child contacts of multidrug-resistant tuberculosis: a prospective cohort study.

BACKGROUND: Evidence is limited to guide the management of children exposed to multidrug-resistant (MDR) tuberculosis. We aimed to study the tolerability and toxicity of a standard preventive therapy regimen given to children exposed to infectious MDR tuberculosis, and explore risk factors for poor outcome. METHODS: In this prospective cohort study in the Western Cape, South Africa, children <5 years of age, or human immunodeficiency virus (HIV)-positive children aged <15 years, were recruited from May 2010 through April 2011 if exposed to an ofloxacin-susceptible, MDR tuberculosis source case. Children were started on preventive therapy as per local guidance: ofloxacin, ethambutol, and high-dose isoniazid for 6 months. Standardized measures of adherence and adverse events were recorded; poor outcome was defined as incident tuberculosis or death from any cause. RESULTS: One hundred eighty-six children were included, with a median age of 34 months (interquartile range, 14-47 months). Of 179 children tested for HIV, 9 (5.0%) were positive. Adherence was good in 141 (75.8%) children. Only 7 (3.7%) children developed grade 3 adverse events. One child (0.5%) died and 6 (3.2%) developed incident tuberculosis during 219 patient-years of observation time. Factors associated with poor outcome were age <1 year (rate ratio [RR], 10.1; 95% confidence interval [CI], 1.65-105.8; P = .009), HIV-positive status (RR, 10.6; 95% CI, 1.01-64.9; P = .049), exposure to multiple source cases (RR, 6.75; 95% CI, 1.11-70.9; P = .036) and poor adherence (RR, 7.50; 95% CI, 1.23-78.7; P = .026). CONCLUSIONS: This 3-drug preventive therapy regimen was well tolerated and few children developed tuberculosis or died if adherent to therapy. The provision of preventive therapy to vulnerable children following exposure to MDR tuberculosis should be considered.

Canadian Physicians' Use of Intramuscular Botulinum Toxin Injections for Shoulder Spasticity: A National Cross-Sectional Survey.

Spasticity of the upper extremity can result in severe pain, along with many complications that can impair a patient's activities of daily living. Failure to treat patients with spasticity of the upper limb can result in a decrease in the range of motion of joints and contracture development, leading to further restriction in daily activities. We aimed to investigate the practice patterns of Canadian physicians who utilize Botulinum toxin type-A (BoNT-A) injections in the management of shoulder spasticity. 50 Canadian Physical Medicine and Rehabilitation (PM&R) physicians completed a survey with an estimated completion rate of (36.23%). The demographics of the survey participants came from a variety of provinces, clinical settings, and patient populations. The most common muscle injected for shoulder adduction and internal rotation spasticity was the pectoralis major, this was followed by latissimus dorsi, pectoralis minor, subscapularis and teres major. Injection of BoNT-A for problematic post-stroke shoulder spasticity was common, with (81.48%) of participants responding that it was always or often used in their management of post-stroke spasticity (PSS). Dosing of BoNT-A demonstrated variability for the muscle injected as well as the type of toxin used. The goals of the patients, caregivers, and practitioners were used to help guide the management of these patients. As a result, the practice patterns of Canadian physicians who treat shoulder spasticity are varied, due to numerous patient factors. Future studies are needed to analyze optimal treatment patterns, and the development of algorithms to standardize care.

Outcomes of a pilot water protocol project in a rehabilitation setting.

There is considerable clinical interest in the risks and benefits of offering oral water intake, in the form of water protocols, to patients with thin-liquid dysphagia. We describe the design and implementation of a water protocol for patients in a rehabilitation setting with videofluoroscopically confirmed thin-liquid aspiration. The GF Strong Water Protocol (GFSWP) is an interdisciplinary initiative, with roles and accountabilities specified for different members of the interprofessional health-care team. Rules of the water protocol specify mode of water access (independent, supervised), the implementation of any safe swallowing strategies recommended on the basis of the patient's videofluoroscopy, and procedures for evaluating and addressing oral care needs. Trial implementation of the water protocol in 15 participants showed that they remained free of adverse events, including pneumonia, over the course of an initial 14-day trial and continuing until discharge from the facility (range = 13-108 days). Seven participants were randomly assigned to a 14-day control phase in which they received standard care (without water access). Fluid intake measures taken after the oral water intake phase were increased (mean = 1,845 cc; 95% confidence interval: 1,520-2,169 cc) compared to those in the control phase (mean = 1,474 cc; 95% CI: 1,113-1,836 cc), with oral water intake measures comprising, on average, 563 cc (range = 238-888 cc) of the total post water trial fluid intake values. Fluid intake increased at least 10% of the calculated fluid requirements in 11/15 participants who received oral water access. These participants reported favorable quality-of-life outcomes, measured using the Swal-QOL. These findings support the implementation of the GFSWP, including its exclusion criteria, rules, and plans of care, for rehabilitation patients who aspirate thin liquids.

"No One Manages It; We Just Sign Them Up and Do It": A Whole System Analysis of Access to Healthcare in One Remote Australian Community.

OBJECTIVE: To assess the accessibility, availability and utilisation of a comprehensive range of community-based healthcare services for Aboriginal people and describe contributing factors to providing effective healthcare services from the provider perspective. SETTING: A remote community in New South Wales, Australia. PARTICIPANTS: Aboriginal and non-Aboriginal health and education professionals performing various roles in healthcare provision in the community. DESIGN: Case study. METHODOLOGY: The study was co-designed with the community. A mixed-methods methodology was utilised. Data were gathered through structured interviews. Descriptive statistics were used to analyse the availability of 40 health services in the community, whilst quotations from the qualitative research were used to provide context for the quantitative findings. RESULTS: Service availability was mapped for 40 primary, specialised, and allied health services. Three key themes emerged from the analysis: (1) there are instances of both underservicing and overservicing which give insight into systemic barriers to interagency cooperation; (2) nurses, community health workers, Aboriginal health workers, teachers, and administration staff have an invaluable role in healthcare and improving patient access to health services and could be better supported through further funding and opportunities for specialised training; and (3) visiting and telehealth services are critical components of the system that must be linked to existing community-led primary care services. CONCLUSION: The study identified factors influencing service availability, accessibility and interagency cooperation in remote healthcare services and systems that can be used to guide future service and system planning and resourcing.

2022 American College of Rheumatology/American Association of Hip and Knee Surgeons Guideline for the Perioperative Management of Antirheumatic Medication in Patients With Rheumatic Diseases Undergoing Elective Total Hip or Total Knee Arthroplasty.

OBJECTIVE: To develop updated guidelines for the perioperative management of disease-modifying medications for patients with rheumatic diseases, specifically those with inflammatory arthritis (IA) and those with systemic lupus erythematosus (SLE), undergoing elective total hip arthroplasty (THA) or elective total knee arthroplasty (TKA). METHODS: We convened a panel of rheumatologists, orthopedic surgeons, and infectious disease specialists, updated the systematic literature review, and included currently available medications for the clinically relevant population, intervention, comparator, and outcomes (PICO) questions. We used the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology to rate the quality of evidence and the strength of recommendations using a group consensus process. RESULTS: This guideline updates the 2017 recommendations for perioperative use of disease-modifying antirheumatic therapy, including traditional disease-modifying antirheumatic drugs, biologic agents, targeted synthetic small-molecule drugs, and glucocorticoids used for adults with rheumatic diseases, specifically for the treatment of patients with IA, including rheumatoid arthritis and spondyloarthritis, those with juvenile idiopathic arthritis, or those with SLE who are undergoing elective THA or TKA. It updates recommendations regarding when to continue, when to withhold, and when to restart these medications and the optimal perioperative dosing of glucocorticoids. CONCLUSION: This updated guideline includes recently introduced immunosuppressive medications to help decision-making by clinicians and patients regarding perioperative disease-modifying medication management for patients with IA and SLE at the time of elective THA or TKA.
