ObjectivesAmerican College of Rheumatology Composite Response Index in Systemic Sclerosis (ACR-CRISS) is a composite endpoint to assess the likelihood of improvement in diffuse systemic sclerosis. ACR-CRISS is a weighted score and includes five core set measures: modified Rodnan skin score, FVC% predicted, health assessment questionnaire–disability index, and patient and clinician global assessments.MethodsWe analysed core set measures from 354 participants who participated in three placebo-controlled trials. We generated 10 development datasets, randomly selected from 2/3 of the participants, stratified by study and treatment group. The remaining participants (1/3 of the participants) formed the validation sets. Risk differences (RDs) between active and placebo treatments were calculated by averaging over the replicate datasets; bootstrap 95% CIs for the RDs to estimate the magnitude of treatment effects.ResultsIn the development sets (n=237), the proportion of participants in the active group had statistically higher improvement in >1 of 5 core set measures versus the placebo group. For example, the proportion who improved by ≥20% in ≥3 core set measures was 49.4% in the active versus338.9% in the placebo; RD: 10.5%, 95% CI4.9 % to 16.1%. In the validation sets (n=117), the proportion who improved by ≥20% in ≥3 core set measures was 50.3% in the active versus35.63% in the placebo (RD:114.8%, 95% CI 3.1% to225.7%). Similar trends were seen with larger percentage cut-offs.ConclusionRevised CRISS, as assessed by the proportion of participants who improved by a certain percentage in ≥3 of 5 core set measures, is a potential new composite outcome measure.

Background
Early diffuse cutaneous systemic sclerosis (dcSSc) has the highest case fatality among rheumatic diseases. We report baseline characteristics, current immunosuppressive therapies, progression of skin and internal organ involvement, and mortality in a multicenter prospective cohort from the United States (US) of America.
Methods
We performed a longitudinal analysis of participants from 12 US centers, from April 2012 to July 2020. All participants had early dcSSc or were at-risk for dcSSc, with ≤2 years since the first non-Raynaud’s phenomenon (RP) symptom.
Results
Three hundred one patients were included with a baseline median disease duration of 1.2 years since RP and a mean modified skin score of 21.1 units. At baseline, 263 (87.3%) had definite dcSSc and 38 (12.7%) were classified as at-risk; 112 (49.6%) patients were positive for anti-RNA polymerase III antibodies. The median follow-up duration was 24.5 months (IQR = 10.3–40.7 months). One hundred ninety (63.1%) participants were treated with an immunosuppressive therapy, of which mycophenolate mofetil was most used at baseline and follow-up. Of 38 who were classified as at-risk at baseline, 27 (71%) went on to develop dcSSc; these patients were characterized by higher baseline mean HAQ-DI (0.8 versus 0.4, p = 0.05) and higher baseline mRSS (8.8 versus 4.4, p < 0.01) in comparison with those who remained as limited cutaneous SSc. In the overall cohort, 48 participants (21.1%) had clinically significant worsening of skin fibrosis, mainly occurring in the first year of follow-up; 41 (23.3%) had an absolute forced vital capacity decline of ≥10%. Twenty participants (6.6%) died, of which 18 died in the first 3 years of follow-up. Cardiac involvement (33.3%), gastrointestinal dysmotility (22.2%), and progressive interstitial lung disease (ILD) (16.7%) were the main causes of death.
Conclusion
This US cohort highlights the management of early SSc in the current era, demonstrating progression of skin and lung involvement despite immunosuppressive therapy and high mortality due to cardiac involvement.

Elevated neutrophil extracellular traps in systemic sclerosis-associated vasculopathy and suppression by a synthetic prostacyclin analog
2024
Objectives
Neutrophils and neutrophil extracellular traps (NETs) contribute to the vascular complications of multiple diseases, but their role in systemic sclerosis (SSc) is understudied. We sought to test the hypothesis that NETs are implicated in SSc vasculopathy and that treatment with prostacyclin analogs may ameliorate SSc vasculopathy not only through vasodilation but also by inhibiting NET release.
Methods
Blood from 125 patients with SSc (87 diffuse cutaneous SSc and 38 limited cutaneous SSc) was collected at a single academic medical center. Vascular complications such as digital ulcers, pulmonary artery hypertension, and scleroderma renal crisis were recorded. The association between circulating NETs and vascular complications was determined using in vitro and ex vivo assays. The impact of the synthetic prostacyclin analog epoprostenol on NET release was determined.
Results
Neutrophil activation and NET release were elevated in patients with SSc-associated vascular complications compared to matched patients without vascular complications. Neutrophil activation and NETs positively correlated with soluble E-selectin and VCAM-1, circulating markers of vascular injury. Treatment of patients with digital ischemia with a synthetic prostacyclin analog boosted neutrophil cyclic AMP, which was associated with the blunting of NET release and reduced NETs in circulation.
Conclusion
Our study demonstrates an association between NETs and vascular complications in SSc. We also identified the potential for an additional therapeutic benefit of synthetic prostacyclin analogs, namely to reduce neutrophil hyperactivity and NET release in SSc patients.
Key message
•
Neutrophils and NETs are understudied in the pathogenesis of SSc.
•
Plasma NETs are associated with SSc vascular complications and may identify patients deserving proactive treatments.
•
Prostacyclin analogs potentially protect against SSc vasculopathy-related NET release by boosting intracellular cyclic AMP.

Trajectories of Recovery after Intravenous propofol versus inhaled VolatilE anaesthesia (THRIVE) randomised controlled trial in the USA: A protocol
2025
IntroductionMillions of patients receive general anaesthesia every year with either propofol total intravenous anaesthesia (TIVA) or inhaled volatile anaesthesia (INVA). It is currently unknown which of these techniques is superior in relation to patient experience, safety and clinical outcomes. The primary aims of this trial are to determine (1) whether patients undergoing (a) major inpatient surgery, (b) minor inpatient surgery or (c) outpatient surgery have a superior quality of recovery after INVA or TIVA and (2) whether TIVA confers no more than a small (0.2%) increased risk of definite intraoperative awareness than INVA.Methods and analysisThis protocol was co-created by a diverse team, including patient partners with personal experience of TIVA or INVA. The design is a 13 000-patient, multicentre, patient-blinded, randomised, comparative effectiveness trial. Patients 18 years of age or older, undergoing elective non-cardiac surgery requiring general anaesthesia with a tracheal tube or laryngeal mask airway will be eligible. Patients will be randomised 1:1 to one of two anaesthetic approaches, TIVA or INVA, using minimisation. The primary effectiveness endpoints are Quality of Recovery-15 (QOR-15) score on postoperative day (POD) 1 in patients undergoing (1) major inpatient surgery, (2) minor inpatient surgery or (3) outpatient surgery, and the primary safety endpoint is the incidence of unintended definite intraoperative awareness with recall in all patients, assessed on POD1 or POD30. Secondary endpoints include QOR-15 score on POD0, POD2 and POD7; incidence of delirium on POD0 and POD1; functional status on POD30 and POD90; health-related quality of life on POD30, POD90, POD180 and POD365; days alive and at home at POD30; patient satisfaction with anaesthesia at POD2; respiratory failure on POD0; kidney injury on POD7; all-cause mortality at POD30 and POD90; intraoperative hypotension; moderate-to-severe intraoperative movement; unplanned hospital admission after outpatient surgery in a free-standing ambulatory surgery centre setting; propofol-related infusion syndrome and malignant hyperthermia.Ethics and disseminationThis study is approved by the ethics board at Washington University, serving as the single Institutional Review Board for all participating sites. Recruitment began in September 2023. Dissemination plans include presentations at scientific conferences, scientific publications, internet-based educational materials and mass media.Trial registration numberNCT05991453.

Tofacitinib blocks IFN-regulated biomarker genes in skin fibroblasts and keratinocytes in a systemic sclerosis trial
2022
BACKGROUNDSystemic sclerosis (SSc) is an autoimmune, connective tissue disease characterized by vasculopathy and fibrosis of the skin and internal organs.METHODSWe randomized 15 participants with early diffuse cutaneous SSc to tofacitinib 5 mg twice a day or matching placebo in a phase I/II double-blind, placebo-controlled trial. The primary outcome measure was safety and tolerability at or before week 24. To understand the changes in gene expression associated with tofacitinib treatment in each skin cell population, we compared single-cell gene expression in punch skin biopsies obtained at baseline and 6 weeks following the initiation of treatment.RESULTSTofacitinib was well tolerated; no participants experienced grade 3 or higher adverse events before or at week 24. Trends in efficacy outcome measures favored tofacitnib. Baseline gene expression in fibroblast and keratinocyte subpopulations indicated IFN-activated gene expression. Tofacitinib inhibited IFN-regulated gene expression in SFRP2/DPP4 fibroblasts (progenitors of myofibroblasts) and in MYOC/CCL19, representing adventitial fibroblasts (P < 0.05), as well as in the basal and keratinized layers of the epidermis. Gene expression in macrophages and DCs indicated inhibition of STAT3 by tofacitinib (P < 0.05). No clinically meaningful inhibition of T cells and endothelial cells in the skin tissue was observed.CONCLUSIONThese results indicate that mesenchymal and epithelial cells of a target organ in SSc, not the infiltrating lymphocytes, may be the primary focus for therapeutic effects of a Janus kinase inhibitor.TRIAL REGISTRATIONClinicalTrials.gov NCT03274076.FUNDINGPfizer, NIH/National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) R01 AR070470, NIH/NIAMS K24 AR063120, Taubman Medical Research Institute and NIH P30 AR075043, and NIH/NIAMS K01 AR072129.

Prevalence and determinants of oral and cervicogenital HPV infection: Baseline analysis of the Michigan HPV and Oropharyngeal Cancer (MHOC) cohort study
2022
We determined baseline oral and cervicogenital human papillomavirus (HPV) prevalence and determinants of infection in the Michigan HPV and Oropharyngeal Cancer (MHOC) study. We enrolled 394 college-age and older participants of both sexes in Ann Arbor, Michigan and the surrounding area. All participants provided an oral sample at baseline, and 130 females provided a cervicogenital sample. Samples were tested for 18 HPV genotypes using polymerase chain reaction (PCR) MassArray. Participants filled out sociodemographic and behavioral questionnaires. Prevalence ratios for HPV oral or cervicogenital prevalence by predictor variables were estimated in univariable log-binomial models. Analysis was conducted 2018–20. In the full cohort, baseline oral HPV prevalence was 10.0% for any detected genotype (among the 338 valid oral tests at baseline) and 6.5% for high-risk types, and cervicogenital prevalence was 20.0% and 10.8%, respectively (among the 130 first valid cervicogenital tests). Oral HPV prevalence did not vary by sex, with 10.5% of women and 9.0% of men having an infection. We found a high prevalence of oral and cervicogenital HPV infection in college-age participants reporting no lifetime sexual partners. Reporting a single recent partner was associated with a lower oral HPV prevalence (PR 0.39, 95% CI: 0.16, 0.96) than reporting no recent (but at least one ever) partner. No similar protective effect was seen for cervicogenital HPV. Both oral and cervicogenital prevalence increased with the number of recent partners for most sexual behaviors. We observed an ecological fallacy masking the direction of impact of vaccination on HPV prevalence in the full cohort compared to the college-aged and the age 23+ populations considered separately. Substance use was not significantly associated with oral or cervicogenital HPV infection. Many studies report substantially higher oral HPV infection prevalence in men than in women. That difference may not be uniform across populations in the US.

Objective Scleroderma‐associated autoantibodies (SSc‐Abs) are specific in participants (pts) with systemic sclerosis and are associated with organ involvement. Our objective was to assess the influence of baseline SSc‐Abs on the trajectories of the clinical outcome assessments (COAs) in a phase III randomized controlled trial. Methods We used data on both the groups who received placebo (Pbo) and tocilizumab from the focuSSced trial. The SSc‐Ab panel was assessed centrally. We analyzed four groups with SSc‐Abs: anti–topoisomerase 1 antibody (ATA), anti–RNA polymerase 3 antibody (RNAP3), anti‐centromere antibody, and negative for all three (triple negative). We assessed the impact of baseline SSc‐Abs on six COAs: modified Rodnan skin score (mRSS), forced vital capacity (FVC%), Health Assessment Questionnaire Disability Index, patient and clinical global assessments, and American College of Rheumatology (ACR) Composite Response Index in Systemic Sclerosis (CRISS). Results We observed that all COAs, except for FVC%, improved for the group who received Pbo during the 48‐week period. For mRSS, pts with RNAP3 showed the largest Pbo effect (7.20 per year, n = 14) and smallest for ATA (3.28 per year, n = 49). This trend was also seen for the ACR CRISS (0.00–1.00 scale), with median improvement at week 48 of 0.94 for RNAP3 versus 0.01 for ATA. ATA enriched for FVC% decline of 7.34% per year versus 2.54% per year for RNAP3. In the group who received tocilizumab, similar changes were seen in the mRSS and ACR CRISS with preservation of lung function, irrespective of SSc‐Ab type. Conclusion Our result shows a differential effect of SSc‐Abs on the trajectories of COAs over 48 weeks in group who received Pbo. These findings highlight the importance of incorporating SSc‐Abs in trial design, either as a stratification factor or limiting the SSc‐Abs that are included in the trials.

There is growing interest in, but limited data about, intestinal bile acid transport inhibitors as treatment for cholestatic liver disease. The current analyses combine two similar randomized placebo‐controlled trials with subsequent extension phases investigating the impact of maralixibat in children with severe cholestasis secondary to Alagille Syndrome (n = 57). The primary outcomes were measures of pruritus (ItchRO[Obs]) and clinician scratch scale (CSS), both increasing in severity from 0 to 4) and quality of life (QoL) (Parent PedsQL and Multidimensional Fatigue Scale module [MFS] scaled 0–100 with increased QoL) at week 48 of the extension phase relative to the baseline of the placebo‐controlled trials (week 13). Secondary assessments included other clinical and biochemical parameters assessed in participants at week 72 or end of treatment (after week 48). At week 48, statistically and clinically significant least square mean (95% CI) improvements in pruritus and QoL were observed (ItchRO[Obs] −1.59 [−1.81, −1.36], CSS −1.36 [−1.67, −1.05], PedsQL +10.17 [4.48, 15.86], and multidimension fatigue [MFS] +13.97 [7.85, 20.08]). At week 48, serum bile acids, platelet count, and cholesterol decreased, whereas alanine aminotransferase (ALT) increased and total bilirubin (TB) and albumin were stable. Changes were durable at week 72 and end of treatment. There were no deaths; 2 participants underwent liver transplantation. Study drug was discontinued in 9 participants after treatment‐emergent adverse events, 6 of which were events of increased ALT or TB. Conclusion: Maralixibat administration was associated with marked improvement in pruritus and QoL. Interpretation of these findings is complicated by the complex natural history of severe cholestasis in Alagille syndrome. Potential attribution of an impact of maralixibat or other IBATi on disease progression in pediatric cholestasis may require continued long‐term follow‐up of individuals receiving IBATi and a relevant contemporaneous natural history cohort. Future investigations of IBATi in cholestatic liver disease may need to delineate the mechanisms of action including effects on bile acid composition, the intestinal microbiome and the gut‐liver axis.

Objective Mycophenolate mofetil (MMF) can stabilize or improve lung function in systemic sclerosis–related interstitial lung disease (SSc‐ILD). We hypothesized that combining MMF with pirfenidone (PFD) would produce a significantly more rapid and/or greater improvement in lung function. Methods A randomized (1:1), double‐blind, placebo (PLA)‐controlled phase 2 trial was conducted in SSc‐ILD in which patients received PFD or PLA (801 mg three times daily) along with MMF (1,500 mg twice daily) for 18 months. The primary outcome was change in percent predicted forced vital capacity (FVC‐%). Linear mixed‐effects models assessed treatment differences in a modified intention‐to‐treat population. Results Only fifty‐one of 150 intended subjects (34%) were randomized (MMF+PLA, n = 24; MMF+PFD, n = 27). The FVC‐% improved from baseline to 18 months by 2.24 ± 1.35 (least‐squares mean [LSM] ± SEM) in the MMF+PLA group and 2.09 ± 1.28 in the MMF+PFD group (LSM treatment difference −0.14; P = 0.93). Median time to achieve a ≥3% improvement in FVC‐% was numerically faster in the MMF+PFD versus MMF+PLA group (12.3 vs 17.8 months, respectively), but the difference was not significant (P = 0.33). For secondary outcomes, only the change over 18 months in the Patient‐Reported Outcomes Measurement Information System 29‐item physical function score, favoring MMF+PFD, reached statistical significance (P = 0.04). Although other related patient‐reported outcomes (PROs) numerically favored the MMF+PFD group, as did quantitative high‐resolution computed tomography measures of ILD, the differences between groups did not reach statistical significance. Early withdrawals from study medication and adverse events of special interest were numerically greater with MMF+PFD (n = 8 vs 2 and n = 20 vs 7, respectively). Conclusion In this underpowered study, there was no statistically significant treatment difference in overall change in FVC‐% between groups. MMF+PFD was not as well tolerated as MMF+PLA.

Methods to identify children with cystic fibrosis (CF) at risk for development of advanced liver disease are lacking. We aim to determine the association between liver stiffness measurement (LSM) by vibration‐controlled transient elastography (VCTE) with research ultrasound (US) patterns and conventional hepatic markers as a potential means to follow liver disease progression in children with CF. ELASTIC (Longitudinal Assessment of Transient Elastography in CF) is a nested cohort of 141 patients, ages 7‐21, enrolled in the Prediction by US of Risk of Hepatic Cirrhosis in CF (PUSH) Study. We studied the association between LSM with research‐grade US patterns (normal [NL], heterogeneous [HTG], homogeneous [HMG], or nodular [NOD]) and conventional hepatic markers. In a subgroup (n = 79), the association between controlled attenuation parameter (CAP) and US pattern was explored. Among 133 subjects undergoing VCTE, NOD participants (n = 26) had a significantly higher median (interquartile range) LSM of 9.1 kPa (6.3, 15.8) versus NL (n = 72, 5.1 kPa [4.2, 7.0]; P < 0.0001), HMG (n = 17, 5.9 kPa [5.2, 7.8]; P = 0.0013), and HTG (n = 18, 6.1 kPa [4.7, 7.0]; P = 0.0008) participants. HMG participants (n = 14) had a significantly higher mean CAP (SD) (270.5 dB/m [61.1]) compared with NL (n = 40, 218.8 dB/m [46.5]; P = 0.0027), HTG (n = 10, 218.1 dB/m [60.7]; P = 0.044), and NOD (n = 15, 222.7 dB/m [56.4]; P = 0.041) participants. LSM had a negative correlation with platelet count (rs = ‐0.28, P = 0.0071) and positive correlation with aspartate aminotransferase–to‐platelet ratio index (rs = 0.38, P = 0.0002), Fibrosis‐4 index (rs = 0.36, P = 0.0007), gamma‐glutamyltransferase (GGT; rs = 0.35, P = 0.0017), GGT‐to‐platelet ratio (rs = 0.35, P = 0.003), and US spleen size z‐score (rs = 0.27, P = 0.0073). Conclusion: VCTE is associated with US patterns and conventional markers in patients with liver disease with CF.
