Pain and Physical and Psychological Symptoms in Ambulatory HIV Patients in the Current Treatment Era

Context HIV infection has become a manageable chronic disease. There are few studies of pain and symptoms in the current treatment era. Objectives The primary objective was to determine the prevalence of and risk factors for pain and physical and psychological symptoms in a population of ambulatory HIV patients. Methods We performed a cross-sectional study using the Brief Pain Inventory and the Memorial Symptom Assessment Scale. Results We evaluated 156 individuals with a median age of 47.5 years (range 21–71), median time since HIV diagnosis of 11 years (range 3(interquartile range [IQR] 308–683). The majority (125, 80.6%) had an undetectable viral load. Seventy-six (48.7%) reported pain, of whom 39 (51.3%) had moderate to severe pain, and 43 (57.3%) had pain that caused moderate to severe interference with their lives. The median number of symptoms was eight (IQR 5–14.5) of 32 queried. In multivariable analyses, patients with psychiatric illness were 39.8% more likely to have pain (P Conclusion Pain and other physical and psychological symptoms were common among ambulatory HIV patients. Pain and symptoms were strongly associated with psychiatric illness and IV drug use. Future investigation should evaluate interventions that include psychiatric and substance abuse components for HIV patients with pain

Disproportionate articular pain is a frequent phenomenon in rheumatoid arthritis and responds to treatment with sarilumab

Objectives In some patients with RA, joint pain is more severe than expected based on the amount of joint swelling [referred to as disproportionate articular pain (DP)]. We assessed DP prevalence and the effects of sarilumab, an IL-6 inhibitor, on DP. Methods Data from RA patients treated with placebo or 200 mg sarilumab in the phase 3 randomized controlled trials (RCTs) MOBILITY and TARGET, adalimumab 40 mg or sarilumab 200 mg in the phase 3 RCT MONARCH and sarilumab 200 mg in open-label extensions (OLEs) were used. DP was defined as an excess tender 28-joint count (TJC28) over swollen 28-joint count (SJC28) of ≥7 (TJC28 − SJC28 ≥ 7). Treatment response and disease activity were determined for patients with and without DP. Results Of 1531 sarilumab 200 mg patients from RCTs, 353 (23%) had baseline DP. On average, patients with DP had higher 28-joint DAS using CRP (DAS28-CRP) and pain scores than patients without DP, whereas CRP levels were similar. After 12 and 24 weeks, patients with baseline DP treated with sarilumab were more likely to be DP-free than those treated with placebo or adalimumab. In RCTs, more sarilumab-treated patients achieved low disease activity vs comparators, regardless of baseline DP status. In OLEs, patients were more likely to lose rather than gain DP status. Conclusion About one-quarter of patients with RA experienced DP, which responded well to sarilumab. These data support the concept that other mechanisms (potentially mediated via IL-6) in addition to inflammation may contribute to DP in RA

Real-world Sarilumab use and rule testing to predict treatment response in patients with rheumatoid arthritis: findings from the rise registry

Introduction: Clinical trial findings may not be generalizable to routine practice. This study evaluated sarilumab effectiveness in patients with rheumatoid arthritis (RA) and tested the real-world applicability of a response prediction rule, derived from trial data using machine learning (based on C-reactive protein [CRP] > 12.3 mg/l and seropositivity [anticyclic citrullinated peptide antibodies, ACPA +]). Methods: Sarilumab initiators from the ACR-RISE Registry, with ≥ 1 prescription on/after its FDA approval (2017–2020), were divided into three cohorts based on progressively restrictive criteria: Cohort A (had active disease), Cohort B (met eligibility criteria of a phase 3 trial in RA patients with inadequate response/intolerance to tumor necrosis factor inhibitors [TNFi]), and Cohort C (characteristics matched to the phase 3 trial baseline). Mean changes in Clinical Disease Activity Index (CDAI) and Routine Assessment of Patient Index Data 3 (RAPID3) were evaluated at 6 and 12 months. In a separate cohort, predictive rule was tested based on CRP levels and seropositive status (ACPA and/or rheumatoid factor); patients were categorized into rule-positive (seropositive with CRP > 12.3 mg/l) and rule-negative groups to compare the odds of achieving CDAI low disease activity (LDA)/remission and minimal clinically important difference (MCID) over 24 weeks. Results: Among sarilumab initiators (N = 2949), treatment effectiveness was noted across cohorts, with greater improvement noted for Cohort C at 6 and 12 months. Among the predictive rule cohort (N = 205), rule-positive (vs. rule-negative) patients were more likely to reach LDA (odds ratio: 1.5 [0.7, 3.2]) and MCID (1.1 [0.5, 2.4]). Sensitivity analyses (CRP > 5 mg/l) showed better response to sarilumab in rule-positive patients. Conclusions: In real-world setting, sarilumab demonstrated treatment effectiveness, with greater improvements in the most selective population, mirroring phase 3 TNFi-refractory and rule-positive RA patients. Seropositivity appeared a stronger driver for treatment response than CRP, although optimization of the rule in routine practice requires further data

Identification of a rule to predict response to sarilumab in patients with rheumatoid arthritis using machine learning and clinical trial data

Introduction In rheumatoid arthritis, time spent using ineffective medications may lead to irreversible disease progression. Despite availability of targeted treatments, only a minority of patients achieve sustained remission, and little evidence exists to direct the choice of biologic disease-modifying antirheumatic drugs in individual patients. Machine learning was used to identify a rule to predict the response to sarilumab and discriminate between responses to sarilumab versus adalimumab, with a focus on clinically feasible blood biomarkers. Methods The decision tree model GUIDE was trained using a data subset from the sarilumab trial with the most biomarker data, MOBILITY, to identify a rule to predict disease activity after sarilumab 200 mg. The training set comprised 18 categorical and 24 continuous baseline variables; some data were omitted from training and used for validation by the algorithm (cross-validation). The rule was tested using full datasets from four trials (MOBILITY, MONARCH, TARGET, and ASCERTAIN), focusing on the recommended sarilumab dose of 200 mg. Results In the training set, the presence of anti-cyclic citrullinated peptide antibodies, combined with C-reactive protein > 12.3 mg/l, was identified as the “rule” that predicts American College of Rheumatology 20% response (ACR20) to sarilumab. In testing, the rule reliably predicted response to sarilumab in MOBILITY, MONARCH, and ASCERTAIN for many efficacy parameters (e.g., ACR70 and the 28-joint disease activity score using CRP [DAS28-CRP] remission). The rule applied less to TARGET, which recruited individuals refractory to tumor necrosis factor inhibitors. The potential clinical benefit of the rule was highlighted in a clinical scenario based on MONARCH data, which found that increased ACR70 rates could be achieved by treating either rule-positive patients with sarilumab or rule-negative patients with adalimumab. Conclusions Well-established and clinically feasible blood biomarkers can guide individual treatment choice. Real-world validation of the rule identified in this post hoc analysis is merited

508 - Dupilumab treatment normalizes intraepidermal nerve fiber density in patients with moderate-to-severe AD

Abstract Introduction Chronic pruritus is a characteristic of atopic dermatitis (AD), contributing to poor quality of life in patients. Alterations in neuroanatomy and neuroarchitecture associated with pruritus secondary to AD are not fully understood. Objectives To explore the role of dupilumab treatment effect on epidermal neuroanatomy by quantifying intraepidermal nerve fiber density (IENFD). Method DIFFERENSTAD (NCT04823130) was an open-label, exploratory study that enrolled patients ≥ 18 years old with moderate-to-severe AD, pruritus lasting > 6 weeks, and Worst Itch Numerical Rating Scale (WI-NRS) ≥ 4, and matched healthy controls. Patients with AD received dupilumab 300 mg every 2 weeks for 16 weeks. Skin biopsies were obtained from patients’ lesional skin at baseline and localization-matched skin at Week 17 (end of treatment, EoT) and from healthy controls. The primary endpoint, IENFD, was defined as number of nerve fibers crossing the basement membrane per millimeter. Results 31 patients with moderate-to-severe AD and 10 matched controls were enrolled. IENFD in patients with AD significantly increased from baseline to EoT (mean [SE]: 7.7 [1.3] at baseline vs 12.1 [2.0] at EoT for patients with AD; P = 0.0017), to levels comparable with the control group (mean [SE]: 12.4 [2.3]; P for control group vs EoT in patients with AD = 0.9374). Mean (SE) Eczema Area and Severity Index (EASI) total score and WI-NRS in dupilumab-treated patients were 22.5 (1.5) and 8.5 (0.3) at baseline, and 5.1 (1.1) and 3.1 (0.5) at EoT (both change from baseline P < 0.0001), respectively. The safety profile was consistent with the known safety profile for dupilumab. Conclusions Dupilumab treatment significantly increased IENFD to levels similar to those of healthy subjects, suggesting restored neuroanatomy in patients with moderate-to-severe AD. Dupilumab also significantly improved clinical signs and pruritus symptoms of AD

Right ventricular morphology and the onset of dyspnea: the MESA-right ventricle study.

BACKGROUND:The association of right ventricular (RV) structure and function with symptoms in individuals without cardiopulmonary disease is unknown. We hypothesized that greater RV mass and RV end-diastolic volume (RVEDV), smaller RV stroke volume (RVSV), and lower RV ejection fraction (RVEF) measured by cardiac magnetic resonance imaging (MRI) in participants free of clinical cardiovascular disease at baseline would be associated with a greater risk of self-reported dyspnea. METHODS:The Multi-Ethnic Study of Atherosclerosis (MESA) performed cardiac MRIs on participants without clinical cardiovascular disease between 2000 and 2002. We excluded subjects who reported "prevalent" dyspnea at the first assessment (24 months). The presence of dyspnea was assessed at 24 months, 42 months, and 60 months from baseline. Cox proportional hazards models were used to examine the relationship between RV measures and incident dyspnea. RESULTS:In the final study sample (N = 2763), there were significant interactions between RV measures and sex in terms of the risk of dyspnea (p<0.05). Among men (N = 1453), lower RV mass (p = 0.003), smaller RVEDV (p<0.001), smaller RV end-systolic volume (RVESV) (p = 0.03) and decreased RVSV (p<0.001) were associated with an increased risk of developing dyspnea after adjusting for covariates. Associations remained after adjusting for left ventricular function and lung function. However, there were no significant associations between RV measures and the risk of dyspnea in women. CONCLUSIONS:Lower RV mass and smaller RV volumes were associated with an increased risk of dyspnea in men, but not in women
