RESUMEN

CD8 T cells are emerging as important mediators in atherosclerosis and cardiovascular disease (CVD). Immune activation may play a particular role in people with HIV (PWH) who are at an increased risk of CVD, even after controlling for known CVD risk factors. Latent CMV infection is associated with increased CVD risk for both PWH and people without HIV, and human CMV-specific CD4 and CD8 T cells are enriched for an immunosenescent phenotype. We previously showed that CMV coinfection in PWH promotes vascular homing and activation of inflammatory CD4 T cells through the CD2-LFA-3 axis. However, the role of CD2/LFA3 costimulation of CD8 T cells in PWH with CMV has yet to be described. In the present study, we demonstrate that CD2 expression on CX3CR1+CD57+CD28- inflammescent CD8 T cells is increased on cells from CMV-seropositive PWH. In vitro CD2/LFA-3 costimulation enhances TCR-mediated activation of these inflammatory CD8 memory T cells. Finally, we show that LFA-3 is highly expressed in aortas of SIV-infected rhesus macaques and in atherosclerotic plaques of people without HIV. Our findings are consistent with a model in which CMV infection enhances CD2 expression on highly proinflammatory CD8 T cells that can then be stimulated by LFA-3 expressed in the vasculature, even in the absence of CD28 costimulation. This model, in which CMV infection exacerbates toxic cytokine and granzyme production by CD8 T cells within the vasculature, highlights a potential therapeutic target in atherosclerosis development and progression, especially for PWH.

RESUMEN

Rheumatology, such as other subspecialties, has both a unique perspective to offer as well as an evolving role to play in the global COVID-19 pandemic. Our field has already contributed meaningfully to the development and repurposing of many of the immune-based therapeutics which are now standard treatments for severe forms of the disease as well as to the understanding of the epidemiology, risk factors and natural history of COVID-19 in immune-mediated inflammatory diseases. Still in evolution is our potential to contribute to burgeoning research efforts in the next phase of the pandemic: the syndrome of postacute sequelae of COVID-19 or Long COVID. While our field brings many assets to the study of Long COVID including our expertise in the investigation of chronic inflammation and autoimmunity, our Viewpoint focuses on the strong similarities between fibromyalgia (FM) and Long COVID. While one can speculate on how embracing and confident practising rheumatologists already are regarding these interrelationships, we assert that in the emerging field of Long COVID the potential lessons from the field of fibromyalgia care and research have been underappreciated and marginalised and most importantly now deserve a critical appraisal.

RESUMEN

Long COVID is a diagnostic label currently given to those suffering from a poorly understood state of incomplete recovery or who have development of a myriad of medically unexplained symptoms occurring in the wake of infection with SARS CoV-2 that is both poorly understood and controversial. Many of the features of one of the most common clinical endotypes of Long COVID are shared by a condition well familiar to all rheumatologists and one with a large body of epidemiologic, clinical and basic research accrued over many decades namely the syndrome of fibromyalgia. Some have recently suggested that Long COVID may merely be a new name for fibromyalgia and that this diagnosis is indeed the condition that many or most may be suffering from as a post infectious sequela. In this Viewpoint we argue that while the parallels between the clinical syndrome experienced by many of those currently labeled as Long COVID and fibromyalgia are strong we should be not too quick to rename the disorder. We further argue that relabeling Long COVID as fibromyalgia is clinically reductionistic and any such relabeling may be attended by harm in both the design and execution of a future research agenda as well to patients who may be inadvertently and unfortunately pejoritised by such labeling. We further explore the parallels and differences between Long COVID and fibromyalgia and outline areas of needed future research and care.

RESUMEN

BACKGROUND: People with human immunodeficiency virus (PWH) are at increased risk for comorbidities, and plasma interleukin 6 (IL-6) levels are among the most robust predictors of these outcomes. Tocilizumab (TCZ) blocks the receptor for IL-6, inhibiting functions of this cytokine. METHODS: This was a 40-week, placebo-controlled, crossover trial (NCT02049437) where PWH on stable antiretroviral therapy (ART) were randomized to receive 3 monthly doses of TCZ or matching placebo intravenously. Following a 10-week treatment period and a 12-week washout, participants were switched to the opposite treatment. The primary endpoints were safety and posttreatment levels of C-reactive protein (CRP) and CD4+ T-cell cycling. Secondary endpoints included changes in inflammatory indices and lipid levels. RESULTS: There were 9 treatment-related toxicities of grade 2 or greater during TCZ administration (mostly neutropenia) and 2 during placebo administration. Thirty-one of 34 participants completed the study and were included in a modified intent-to-treat analysis. TCZ reduced levels of CRP (median decrease, 1819.9 ng/mL, P < .0001; effect size, 0.87) and reduced inflammatory markers in PWH, including D-dimer, soluble CD14, and tumor necrosis factor receptors. T-cell cycling tended to decrease in all maturation subsets after TCZ administration, but was only significant among naive CD4 T cells. Lipid levels, including lipid classes that have been related to cardiovascular disease risk, increased during TCZ treatment. CONCLUSIONS: TCZ is safe and decreases inflammation in PWH; IL-6 is a key driver of the inflammatory environment that predicts morbidity and mortality in ART-treated PWH. The clinical significance of lipid elevations during TCZ treatment requires further study. Clinical Trials Registration. NCT02049437.

RESUMEN

OBJECTIVES: To determine the diagnostic accuracy for high-resolution vessel wall image (HR-VWI) and brain biopsy according to angiographical classification in patients with primary central nervous system vasculitis (PCNSV). METHODS: We extracted the patients with PCNSV who underwent the complete brain MRI protocol and cerebral vascular image from Cleveland Clinic prospective CNS vasculopathy Bioregistry. The large-medium vessel variant (LMVV) was defined as patients with cerebral vasculature indicating vasculitis in proximal or middle arterial segments, whereas vessel involvements in smaller distal branches or normal angiography were considered as the small vessel variant (SVV). We compared clinical demographics, magnetic resonance imaging (MRI) findings, and diagnostic approaches between two variants. RESULTS: In this case-control study that included 34 PCNSV patients, the LMVV group comprised a total of 11 patients (32.4%), and 23 patients (67.6%) were classified as the SVV group. The LMVV had more strong/concentric vessel wall enhancement on HR-VWI (LMVV: 90% (9/10) vs. SVV: 7.1% (1/14), p<0.001). By contrast, meningeal/parenchymal contrast enhancement lesion was more frequently observed in the SVV group (p=0.006). The majority of SVV was diagnosed by brain biopsy (SVV: 78.3% vs. LMVV: 30.8%, p=0.022). The diagnostic accuracy of the brain biopsy was 100% (18/18) in SVV and 57.1% (4/7) in LMVV, respectively (p=0.015). CONCLUSIONS: Diagnostic approach for PCNSV differs concerning the affected vessel size. HR-VWI is a useful imaging modality for the diagnosis of LMVV. Brain biopsy remains the gold standard for proving PCNSV with SVV but is still positive in almost one-third of LMVV.

RESUMEN

OBJECTIVES: Patient centred care is an increasingly important paradigm. Applying a treat-to-target strategy to the impact of the disease in patients' lives seems a very promising tool to serve this purpose. We aimed to evaluate if maximum acceptable impact scores (target-values) defined at the population level provide an appropriate representation for most individual patients. To determine if the individually established target values of impact are consistent enough to be used in a treat-to-target strategy. METHODS: Consecutive patients with rheumatoid arthritis were asked to indicate, in two consecutive visits, the maximum severity of impact they considered acceptable to live with for the rest of their lives, in the seven domains of Rheumatoid Arthritis Impact of Disease score. The individual adequacy of population-based reference values was assessed by measures of dispersion. Stability of individual target-values were evaluated through intraclass correlation coefficient. Socio-demographic, clinical and psychological features were tested as co-factors of stability. RESULTS: 299 patients were included. The dispersion of targets was wide (CV>0.68), thus limiting the use of any population-based single values as targets for the individual patients. Although the mean target values were very similar in both visits for all domains, reliability was poor in all cases (ICCs: 0.37-0.47). Only 25-30% of the patients selected the same target value in the 2 visits. No explanatory factors for (non-)stability were identified. CONCLUSIONS: Quantified impact targets defined at population level are not appropriate for individual patient care. Research on alternative tools to support patient-centred, target-oriented management strategies is warranted.

RESUMEN

OBJECTIVES: High-resolution vessel wall imaging (HR-VWI) often demonstrates strong and concentric vessel wall enhancement (VWE) in patients with central nervous system vasculitis (CNS-V). However, little is known about follow-up VWE characteristics and monitoring the response to treatments. The aim of this study was to investigate serial VWE patterns and its clinical practice through the management of CNS-V. METHODS: We extracted 9 patients with diagnosed of CNS-V who underwent serial HR-VWI (baseline, 1st follow-up, and 2nd follow-up) from Cleveland Clinic CNS vasculopathy registry. VWE were analysed in 17 intracranial artery segments. VWE was graded on a 3-point scale (0; none, 1; mild/eccentric, and 2; strong/concentric). VWE grade for each arterial segment was summed to create a total VWE score. We investigated the relationship between serial VWE patterns and clinical course. RESULTS: In unique 153 intracranial arterial segments, 39 arteries (25.5%) had strong/concentric VWE on baseline HR-VWI. The positive rates of concentric VWE have decreased to 12.4% (19/153) at 1st follow-up and (10/153) 6.5% at 2nd follow-up, respectively (p<0.001). Mean total VWE scores have significantly decreased over time courses (p=0.034). Two patients had relapse at 1st follow-up image. In relapse cases, mean total VWE scores have worsened at 1st follow-up (baseline:2.0 to 1st follow-up: 6.0). After intensive immunosuppressive treatment, mean VWE scores have improved at 2nd follow-up (1st follow-up: 6.0 to 2nd follow-up: 2.0). CONCLUSIONS: Decreasing contrast VWE at follow-up images may indicate good response to treatment in CNS-V. By contrast, relapse patients might have temporal VWE worsening during the clinical course.

RESUMEN

BACKGROUND: Rheumatic and musculoskeletal immune-related adverse events (irAEs) are observed in about 10% of patients with cancer receiving checkpoint inhibitors (CPIs). Given the recent emergence of these events and the lack of guidance for rheumatologists addressing them, a European League Against Rheumatism task force was convened to harmonise expert opinion regarding their identification and management. METHODS: First, the group formulated research questions for a systematic literature review. Then, based on literature and using a consensus procedure, 4 overarching principles and 10 points to consider were developed. RESULTS: The overarching principles defined the role of rheumatologists in the management of irAEs, highlighting the shared decision-making process between patients, oncologists and rheumatologists. The points to consider inform rheumatologists on the wide spectrum of musculoskeletal irAEs, not fulfilling usual classification criteria of rheumatic diseases, and their differential diagnoses. Early referral and facilitated access to rheumatologist are recommended, to document the target organ inflammation. Regarding therapeutic, three treatment escalations were defined: (1) local/systemic glucocorticoids if symptoms are not controlled by symptomatic treatment, then tapered to the lowest efficient dose, (2) conventional synthetic disease-modifying antirheumatic drugs, in case of inadequate response to glucocorticoids or for steroid sparing and (3) biological disease-modifying antirheumatic drugs, for severe or refractory irAEs. A warning has been made on severe myositis, a life-threatening situation, requiring high dose of glucocorticoids and close monitoring. For patients with pre-existing rheumatic disease, baseline immunosuppressive regimen should be kept at the lowest efficient dose before starting immunotherapies. CONCLUSION: These statements provide guidance on diagnosis and management of rheumatic irAEs and aim to support future international collaborations.

RESUMEN

OBJECTIVES: To provide insight into the safety of recombinant zoster vaccine (RZV) in patients with immune-mediated inflammatory diseases (IMID). METHODS: Patients who received RZV in a single-centre rheumatology department were retrospectively included. An IMID flare was defined as (i) a documentation of flare in the office notes or patient portal communication or (ii) new prednisone prescription, in the 12 weeks after each dose. RESULTS: Six-hundred and twenty-two patients were included (67% female, median age 67 years), 8.5% of them experienced adverse events (AEs) and herpes zoster (HZ) incidence was 0.6% after median follow-up of 36 weeks. Of 359 IMID patients: 88 had RA (25%), 50 vasculitis (14%) and 29 PMR (8%). At vaccination, 35% were on glucocorticoids (GC). Fifty-nine patients (16%) experienced a flare, 18 flares occurred in temporal relation to a treatment change (31%). RA patients had the highest flare rate (n = 21, 24%), 25% of patients who flared required adjustment of immunosuppression. In a multivariate analysis, use of GC at time of vaccination was associated with flare after vaccination [odds ratio (OR) 2.31 (1.3-4.1), P =0.004]. A time-to-flare survival analysis (Cox-model) showed that GC was a significant predictor of IMID flare after first RZV dose [hazard ratio (HR) 2.4 (1.3-4.5), P =0.0039] and that a flare after the first dose was associated with flaring after the second RZV dose [HR 3.9 (1.7-9), P =0.0015]. CONCLUSION: RZV administration in patients with IMIDs was generally well-tolerated, though mild flares were not uncommon in the first 12 weeks after vaccination. These data may provide useful information for patient education when considering RZV administration.

RESUMEN

The coronavirus disease 2019 (COVID-19; caused by SARS-CoV-2) pandemic has affected the healthcare system on a global scale, and we utilized the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) 2020 annual meeting to examine how COVID-19 might affect patients with psoriatic disease (PsD) and the clinicians who care for them. Pressing issues and concerns identified included whether having psoriasis increased the risk of acquiring COVID-19, vaccine safety, and the acceptability of telehealth. The general message from rheumatologists, dermatologists, infectious disease specialists, and patient research partners was that data did not suggest that having PsD or its treatment significantly increased risk of infection or more severe disease course, and that the telehealth experience was a success overall.

RESUMEN

PURPOSE OF REVIEW: The introduction of checkpoint inhibitors as well as other allied advances in cancer immunology has made immunotherapy a pillar in the treatment of cancer. At the same time, these therapies have been associated with a remarkable array of immune-mediated toxicities observed in virtually every organ system, a portion of which are rheumatic in nature or multisystem in expression making them of particular relevance for rheumatologists. RECENT FINDINGS: Most of our knowledge of these immune-related adverse events (irAEs) stems from clinical descriptive reports; we lack detailed understanding on immunopathogenesis for most complications. Therapeutic approaches are currently empiric and rely heavily on glucocorticoids and inhibitors of tumor necrosis factor. Serious consideration must now be given to advance our understanding of the immunopathogenesis of this emergent field and to exploit the full depth and breadth of the rich armamentarium of targeted therapies currently available to treat autoimmune and autoinflammatory diseases. SUMMARY: irAEs are and will continue to increase in incidence and pose major hurdles to the continuing success and evolution of cancer immunotherapy. Basic and translational research into pathogenesis of irAEs and clinical trials of targeted therapies for these complications is urgently needed. Rheumatologists are well poised to actively contribute to the care and research of these complications.

RESUMEN

PURPOSE OF REVIEW: The main purpose of this review is to present advances in diagnostics of central nervous system vasculitis (CNS-V). RECENT FINDINGS: Progress in molecular technologies and neuroimaging have added formidably to our knowledge of CNS-V. Next-generation sequencing has the promise to enhance our ability to diagnose, interrogate, and track infectious diseases, making this test attractive and capable of avoiding brain biopsy in cases where CNS infections are suspected. Further the continuum of neuroimaging progress has advanced our ability to diagnose CNS-V. Our capability to visualize the vessel wall have added a great value in differentiating inflammatory from noninflammatory vasculopathies. New genetic variations are being exposed with exome and genome sequences which will aid future diagnosis. SUMMARY: We have witnessed tremendous advances in CNS-V mainly by our ability to rule out mimics. Progress in molecular technologies, neuroimaging and genetic studies will continue to enhance the field further.

RESUMEN

The T-cell response is regulated by the balance between costimulatory and coinhibitory signals. Immune checkpoints are essential for efficient T-cell activation, but also for maintaining self-tolerance and protecting tissues from damage caused by the immune system, and for providing protective immunity. Modulating immune checkpoints can serve diametric goals, such that blocking a coinhibitory molecule can unleash anti-cancer immunity whereas stimulating the same molecule can reduce an over-reaction in autoimmune disease. The purpose of this review is to examine the regulation of T-cell costimulation and coinhibition, which is central to the processes underpinning autoimmunity, transplant rejection and immune evasion in cancer. We will focus on the immunomodulation agents that regulate these unwanted over- and under-reactions. The use of such agents has led to control of symptoms and slowing of progression in patients with rheumatoid arthritis, reduced rejection rates in transplant patients, and prolonged survival in patients with cancer. The management of immune checkpoint inhibitor treatment in certain challenging patient populations, including patients with pre-existing autoimmune conditions or transplant patients who develop cancer, as well as the management of immune-related adverse events in patients receiving antitumor therapy, is examined. Finally, the future of immune checkpoint inhibitors, including examples of emerging targets that are currently in development, as well as recent insights gained using new molecular techniques, is discussed. T-cell costimulation and coinhibition play vital roles in these diverse therapeutic areas. Targeting immune checkpoints continues to be a powerful avenue for the development of agents suitable for treating autoimmune diseases and cancers and for improving transplant outcomes. Enhanced collaboration between therapy area specialists to share learnings across disciplines will improve our understanding of the opposing effects of treatments for autoimmune disease/transplant rejection versus cancer on immune checkpoints, which has the potential to lead to improved patient outcomes.

RESUMEN

OBJECTIVES: Neurosarcoidosis (NS) and primary angiitis of central nervous system (PACNS) are inflammatory diseases affecting central nervous system, with overlapping clinical and pathological characteristics. Distinguishing these diseases is important given distinct therapeutic implications. In this study, we aimed to compare demographic, CSF and MRI characteristics between these two conditions. METHODS: All the clinical, CSF and laboratory characteristics at the time of presentation were retrieved from electronic medical records. Brain and/or spinal cord MRI performed near the time of presentation were blindly evaluated by two neuroradiologists. Data regarding involvement of pachy- and leptomeninges, basal meninges, cranial nerves, cerebral grey and white matter, and spinal cord were recorded for each patient. RESULTS: 78 patients with PACNS and 25 patients with NS were included in the study. Mean age of patients was 43.7 (±16.7) and 43.6 (±12.5) in PACNS and NS, respectively. African-American race was found to be associated with the diagnosis of NS rather than PACNS. Patients with PACNS had higher frequency of cerebral involvement, while patients with NS demonstrated more frequent spinal cord, basal meningeal and cranial nerve involvements. CONCLUSIONS: These findings suggest that MRI can be an efficient tool in distinguishing PACNS from NS. A follow-up study with a larger sample size would be required to validate our results.

RESUMEN

CONTEXT: Research on associations between medical student empathy and demographics, academic background and career interest is limited, lacks representative samples and suffers from single institutional features. This study was designed to fill the gap by examining associations between empathy in patient care, and gender, age, race and ethnicity, academic background and career interest in nationwide, multi-institutional samples of medical students in the United States and to provide more definitive answers regarding the aforementioned associations, with more confidence in the internal and external validity of the findings. METHODS: Four nationwide samples participated in this study (n = 10 751). Samples 1, 2, 3 and 4 included 3616 first-year, 2764 second-year, 2413 third-year and 1958 fourth-year students who completed a web-based survey at the end of the 2017-2018 academic year. The survey included questions on demographics, academic background and career interest, the Jefferson Scale of Empathy, and the Infrequency Scale of the Zuckerman-Kuhlman Personality Questionnaire to control for the effect of 'good impression' response bias. RESULTS: Statistically significant and practically important associations were found between empathy scores and gender (in favour of women), race and ethnicity (in favour of African-American and Hispanic/Latino/Spanish), academic background (in favour of 'Social and Behavioural Sciences' and 'Arts and Humanities' in Samples 1 and 2) and career interest (in favour of 'People-Oriented' and 'Psychiatry' specialties). CONCLUSIONS: Special features of this study (eg, nationwide representative samples, use of a validated instrument for measuring empathy in patient care, statistical control for the effect of 'good impression' response bias, and consistency of findings in different samples from multiple institutions) provide more definitive answers to the issue of correlates of empathy in medical students and increase our confidence in the validity, reliability and generalisability of the results. Findings have implications for career counselling and targeting students who need more guidance to enhance their empathic orientation.

RESUMEN

This American Medical Society for Sports Medicine position statement update is directed towards healthcare providers of patients involved in sport and exercise. There have been significant advances in clinical and scientific research in the understanding of blood-borne pathogens (BBPs), and this update incorporates these advancements. This document is intended as a general guide to clinical practice based on the current state of the evidence, while acknowledging the need for modification as new knowledge becomes available. Confirmed transmission of BBPs during sport is exceedingly rare. There are no well-documented reports of HIV, HCV or HDV transmission during sport. There is also no evidence for universal testing for BBPs as a specific requirement for participation in sports. Competitive athletes and non-athletes should follow appropriate general public health agency recommendations for screening for BBPs, considering their individual risk factors and exposures. Standard (universal) precautions must be followed by those providing care to athletes. Exercise and athletic participation can help promote a healthy lifestyle for persons living with BBPs. Those with acute symptomatic BBP infection should limit exercise intensity based on their current health status. Education is the key tool for preventing BBP transmission. Research gaps include evaluation of the prevalence of BBP infections in competitive athletes, the effects of long-term, intense training on infected athletes and the effects of BBP treatment therapies on performance.

RESUMEN

This AMSSM position statement update is directed toward health care providers of patients involved in sport and exercise. There have been significant advances in clinical and scientific research in the understanding of blood-borne pathogens (BBPs), and this update incorporates these advancements. This document is intended as a general guide to clinical practice based on the current state of evidence, while acknowledging the need for modification as new knowledge becomes available. Confirmed transmission of BBPs during sport is exceedingly rare. There are no well-documented reports of HIV, hepatitis C virus, or hepatitis D virus transmission during sport. There is also no evidence for universal testing for BBPs as a specific requirement for participation in sports. Competitive athletes and nonathletes should follow appropriate general public health agency recommendations for screening for BBPs, considering their individual risk factors and exposures. Standard (universal) precautions must be followed by those providing care to athletes. Exercise and athletic participation can help promote a healthy lifestyle for persons living with BBPs. Those with acute symptomatic BBP infection should limit exercise intensity based on their current health status. Education is the key tool for preventing BBP transmission. Research gaps include evaluation of the prevalence of BBP infections in competitive athletes, the effects of long-term, intense training on infected athletes, and the effects of BBP treatment therapies on performance.

RESUMEN

BACKGROUND: One widely cited study suggested a link between physician empathy and laboratory outcomes in patients with diabetes, but its findings have not been replicated. While empathy has a positive impact on patient experience, its impact on other outcomes remains unclear. OBJECTIVE: To assess associations between physician empathy and glycosylated hemoglobin (HgbA1c) as well as low-density lipoprotein (LDL) levels in patients with diabetes. DESIGN: Retrospective cross-sectional study. PARTICIPANTS: Patients with diabetes who received care at a large integrated health system in the USA between January 1, 2011, and May 31, 2014, and their primary care physicians. MAIN MEASURES: The main independent measure was physician empathy, as measured by the Jefferson Scale of Empathy (JSE). The JSE is scored on a scale of 20-140, with higher scores indicating greater empathy. Dependent measures included patient HgbA1c and LDL. Mixed-effects linear regression models adjusting for patient sociodemographic characteristics, comorbidity index, and physician characteristics were used to assess the association between physician JSE scores and their patients' HgbA1c and LDL. KEY RESULTS: The sample included 4176 primary care patients who received care with one of 51 primary care physicians. Mean physician JSE score was 118.4 (standard deviation (SD) = 12). Median patient HgbA1c was 6.7% (interquartile range (IQR) = 6.2-7.5) and median LDL concentration was 83 (IQR = 66-104). In adjusted analyses, there was no association between JSE scores and HgbA1c (ß = - 0.01, 95%CI = - 0.04, 0.02, p = 0.47) or LDL (ß = 0.41, 95%CI = - 0.47, 1.29, p = 0.35). CONCLUSION: Physician empathy was not associated with HgbA1c or LDL. While interventions to increase physician empathy may result in more patient-centered care, they may not improve clinical outcomes in patients with diabetes.

RESUMEN

OBJECTIVES: Primary angiitis of the central nervous system (PACNS) is a vasculitis confined to the brain and spinal cord, which often presents with severe cognitive and functional deficits. Despite progress in diagnosis, little is still known about long-term outcomes. Our aim was to evaluate long-term functional capabilities, quality of life, and depression, and to determine the effect of treatment duration on patient outcomes. METHODS: We identified patients by ICD-9 codes for cerebral angiitis, and included them if they met two of the three following criteria: inflammatory cerebrospinal fluid (CSF), cerebral angiogram typical of vasculitis, or findings of vasculitis on pathologic examination of brain tissue. Disability was assessed by the Barthel Index, quality of life was assessed by EuroQol, and depression was assessed with Patient Health Questionnaire. RESULTS: Seventy-eight patients met the inclusion criteria, of which 27 responded to the questionnaire (34.6%). Mean follow-up of those who responded was 5.5 years (± 4.7). Nineteen of 27 patients (70.4%) had mild disability; meanwhile, 5 (18.5%) had severe disability. Fourteen of 27 patients (51.9%) had no mobility problem, 18 (66.7%) had no problems with self-care, 15 (55.6%) had no problems with usual activities, 14 (51.9%) had no pain, and 8 (29.6%) had no anxiety. Approximately 70% of patients had minimal or no depression. CONCLUSIONS: This is the longest reported follow-up of patients with PACNS described in the literature to date. Most patients had mild long-term disability and minimal to no depression, which may be reflective of treatment advances.

RESUMEN

OBJECTIVES: To analyse the worldwide occurrence of sicca/Sjögren's (SS) syndrome associated with the use of immune checkpoint inhibitors (ICI) in patients with cancer. METHODS: The ImmunoCancer International Registry (ICIR) is a Big Data-Sharing multidisciplinary network composed by 40 specialists in Rheumatology, Internal Medicine, Immunology and Oncology from 18 countries focused on the clinical and basic research of the immune-related adverse events (irAEs) related to cancer immunotherapies. For this study, patients who were investigated for a clinical suspicion of SS after being exposed to ICI were included. RESULTS: We identified 26 patients (11 women and 15 men, with a mean age at diagnosis of 63.57 years). Underlying cancer included lung (n=12), renal (n=7), melanoma (n=4), and other (n=3) neoplasia. Cancer immunotherapies consisted of monotherapy (77%) and combined regimens (23%). In those patients receiving monotherapy, all patients were treated with PD-1/PD-L1 inhibitors (nivolumab in 9, pembrolizumab in 7 and durvalumab in 4); no cases associated with CTLA-4 inhibitors were identified. The main SS-related features consisted of dry mouth in 25 (96%) patients, dry eye in 17 (65%), abnormal ocular tests in 10/16 (62%) and abnormal oral diagnostic tests in 12/14 (86%) patients. Minor salivary gland biopsy was carried out in 15 patients: histopathological findings consisted of mild chronic sialadenitis in 8 (53%) patients and focal lymphocytic sialadenitis in the remaining 7 (47%); a focus score was measured in 5 of the 6 patients (mean of 1.8, range 1-4). Immunological markers included positive ANA in 13/25 (52%), anti-Ro/ SS-A in 5/25 (20%), RF in 2/22 (9%), anti-La/SS-B in 2/25 (8%), low C3/C4 levels in 1/17 (6%) and positive cryoglobulins in 1/10 (10%). Classification criteria for SS were fulfilled by 10 (62%) out of 16 patients in whom the two key classificatory features were carried out. Among the 26 patients, there were only 3 (11%) who presented exclusively with sicca syndrome without organ-specific autoimmune manifestations. Therapeutic management included measures directed to treat sicca symptoms and therapies against autoimmune-mediated manifestations (glucocorticoids in 42%, second/third-line therapies in 31%); therapeutic response for systemic features was observed in 8/11 (73%). No patient died due to autoimmune involvement. CONCLUSIONS: Patients with Sjögren's syndrome triggered by ICI display a very specific profile different from that reported in idiopathic primary SS, including more frequent occurrence in men, a higher mean age, a predominant immunonegative serological profile, and a notable development of organ-specific autoimmune involvement in spite of the poor immunological profile. The close association found between sicca/Sjögren's syndrome and primarily PD-1 blockade requires further specific investigation.
