Abstract
There are currently limited data on the epidemiology, clinical manifestations, and optimal management of Coronavirus Disease 2019 (COVID-19) in hematopoietic cell transplantation and cellular therapy recipients. Given the experience with other respiratory viruses, we anticipate that patients may develop severe clinical disease and thus provide the following general principles for cancer centers across the nation. These guidelines were developed by members of the American Society for Transplantation and Cellular Therapy Infectious Diseases Special Interest Group. Specific practices may vary depending on local epidemiology and testing capacity, and the guidance provided in this document may change as new information becomes available.

Front Med (Lausanne) 2020; 7:583897. [PMID: 33195334 PMCID: PMC7655919 DOI: 10.3389/fmed.2020.583897] [Citation(s) in RCA: 97] [Impact Index Per Article: 24.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2020] [Accepted: 09/17/2020] [Indexed: 12/14/2022] Open
Abstract
Background: Anti-inflammatory therapies such as IL-6 inhibition have been proposed for COVID-19 in a vacuum of evidence-based treatment. However, abrogating the inflammatory response in infectious diseases may impair a desired host response and pre-dispose to secondary infections. Methods: We retrospectively reviewed the medical record of critically ill COVID-19 patients during an 8-week span and compared the prevalence of secondary infection and outcomes in patients who did and did not receive tocilizumab. Additionally, we included representative histopathologic post-mortem findings from several COVID-19 cases that underwent autopsy at our institution. Results: One hundred eleven patients were identified, of which 54 had received tocilizumab while 57 had not. Receiving tocilizumab was associated with a higher risk of secondary bacterial (48.1 vs. 28.1%; p = 0.029 and fungal (5.6 vs. 0%; p = 0.112) infections. Consistent with higher number of infections, patients who received tocilizumab had higher mortality (35.2 vs. 19.3%; p = 0.020). Seven cases underwent autopsy. In three cases who received tocilizumab, there was evidence of pneumonia on pathology. Of the four cases that had not been given tocilizumab, two showed evidence of aspiration pneumonia and two exhibited diffuse alveolar damage. Conclusions: Experimental therapies are currently being applied to COVID-19 outside of clinical trials. Anti-inflammatory therapies such as anti-IL-6 therapy have the potential to impair viral clearance, pre-dispose to secondary infection, and cause harm. We seek to raise physician awareness of these issues and highlight the need to better understand the immune response in COVID-19.

Abstract
INTRODUCTION Coronavirus disease (COVID-19) can trigger a cytokine response storm (CRS) that is associated with high mortality but for which the underlying pathophysiology and diagnostics are not yet well characterized. This review provides an overview of the underlying immune profile of COVID-19-related CRS as well as laboratory markers for acute diagnosis and chronic follow-up of patients with SARS-CoV-2 and CRS. AREAS COVERED Innate and acquired immune profiles in COVID-19-CRS, RNA-detection methods for SARS-CoV-2 in the setting of CRS including factors that affect assay performance, serology for SARS-CoV-2 in the setting of CRS, and other biomarkers for COVID-19 will be discussed. EXPERT OPINION Studies support the implication of CRS in the pathogenesis, clinical severity and outcome of COVID-19 through the production of multiple inflammatory cytokines and chemokines from activated innate and adaptive immune cells. Although these inflammatory molecules, including IL-6, IL-2 R, IL-10, IP-10 and MCP-1, often correlate with disease severity as possible biomarkers, the pathogenic contributions of individual molecules and the therapeutic benefits of targeting them are yet to be demonstrated. Detection of SARS-CoV-2 RNA is the gold standard method for diagnosis of COVID-19 in the context of CRS but assay performance varies and is susceptible to false-negative results even as patients clinically deteriorate due to decreased viral shedding in the setting of CRS. Biomarkers including CRP, ferritin, D-dimer and procalcitonin may provide early clues about progression to CRS and help identify thrombotic and infectious complications of COVID-19.

Abstract
Intense efforts are underway to evaluate potential therapeutic agents for the treatment of COVID-19. In order to respond quickly to the crisis, the repurposing of existing drugs is the primary pharmacological strategy. Despite the urgent clinical need for these therapies, it is imperative to consider potential safety issues. This is important due to the harm-benefit ratios that may be encountered when treating COVID-19, which can depend on the stage of the disease, when therapy is administered and underlying clinical factors in individual patients. Treatments are currently being trialled for a range of scenarios from prophylaxis (where benefit must greatly exceed risk) to severe life-threatening disease (where a degree of potential risk may be tolerated if it is exceeded by the potential benefit). In this perspective, we have reviewed some of the most widely researched repurposed agents in order to identify potential safety considerations using existing information in the context of COVID-19.

Abstract
BACKGROUND Systemic sclerosis is a connective tissue disease. Skin involvement of the mouth and hand may compromise function and quality of life. Autologous fat grafting has been described as a specific treatment of these clinical features. We report the results of our prospective study designed to treat and prevent skin complications in systemic sclerosis. MATERIALS AND METHODS We treated 25 patients with mouth and/or hand involvement (microstomia, xerostomia, skin sclerosis, Raynaud's phenomenon and long-lasting digital ulcers) with autologous fat grafting, according to the Coleman's technique, around the mouth and/or at the base of each finger. The surgical procedures were repeated in each patient every 6 months for a total of two or three times. Clinical data were collected before the first surgery and again 6 months after each surgical procedure. Pain, skin thickness, saliva production and disability were assessed with validated tests. RESULTS Overall we performed 63 autologous fat grafting sessions (either on the mouth, on the hands or on both anatomical areas). Results at 6 moths after the last session included improvement of xerostomia evaluated with a sialogram, reduction of the skin tension around the mouth and, in the hands, reduction of the Raynaud phenomenon as well as skin thickness. Pain was reduced while the perception of disability improved. Digital ulcers healed completely in 8/9 patients. CONCLUSIONS Our results confirm the efficacy and safety of autologous fat grafting for the treatment of skin complications and digital ulcers due to systemic sclerosis. In addition, the patients' subjective well-being improved. Level of evidence V This journal requires that authors assign a level of evidence to each article.

Abstract
INTRODUCTION COVID-19 is an acute respiratory viral infection that threatens people worldwide, including people with rheumatic disease, although it remains unclear to what extent various antirheumatic disease therapies increase susceptibility to complications of viral respiratory infections. OBJECTIVE The present study undertakes a scoping review of available evidence regarding the frequency and severity of acute respiratory viral adverse events related to antirheumatic disease therapies. METHODS Online databases were used to identify, since database inception, studies reporting primary data on acute respiratory viral infections in patients utilizing antirheumatic disease therapies. Independent reviewer pairs charted data from eligible studies using a standardized data abstraction tool. RESULTS A total of 180 studies were eligible for qualitative analysis. While acknowledging that the extant literature has a lack of specificity in reporting of acute viral infections or complications thereof, the data suggest that use of glucocorticoids, JAK inhibitors (especially high-dose), TNF inhibitors, and anti-IL-17 agents may be associated with an increased frequency of respiratory viral events. Available data suggest no increased frequency or risk of respiratory viral events with NSAIDs, hydroxychloroquine, sulfasalazine, methotrexate, azathioprine, mycophenolate mofetil, cyclophosphamide, or apremilast. One large cohort study demonstrated an association with leflunomide use and increased risk of acute viral respiratory events compared to non-use. CONCLUSION This scoping review identified that some medication classes may confer increased risk of acute respiratory viral infections. However, definitive data are lacking and future studies should address this knowledge gap.

Abstract
This study aimed to describe the utility of the neutrophil-to-lymphocyte ratio (NLR) for predicting bacterial infections in patients with rheumatoid arthritis (RA) treated with Tocilizumab (TCZ). We extracted RA patients treated with TCZ in whom an infection developed between April 2008 and March 2018 from our hospital database. We divided these patients into the bacterial infection and non-bacterial infection groups and compared their background, C-reactive protein (CRP) values, white blood cell count (WBC), the NLR at the time of infection diagnosis, and the ratio of the NLR at the time of infection diagnosis (post-NLR) to the NLR at baseline (pre-NLR). Of the 196 patients who received TCZ, 21 experienced a bacterial infection and 20 had a non-bacterial infection. The median CRP level, WBC count, post-NLR, and post-NLR/pre-NLR ratio in the bacterial infection group were significantly higher than in the non-bacterial infection group. In receiver operating characteristics (ROC) curve analysis for predicting bacterial infection, the area under the curve (AUC) for CRP, WBC, NLR, and the post-NLR/pre-NLR ratio were 0.787, 0.857, 0.887, and 0.975, respectively. The cut-off value of 2.25 for the post-NLR/pre-NLR ratio showed the greatest sensitivity (90.5%) and specificity (100%). The post-NLR/pre-NLR ratio may be a useful surrogate marker for predicting bacterial infections in patients with RA treated with TCZ.

Abstract
Background: Coronavirus disease 2019 (COVID-19) has infected more than 4.4 million people and caused more than 300,000 deaths partly through acute respiratory distress syndrome with propensity to affect African American and Hispanic communities disproportionately. Patients with worse outcomes have exhibited higher blood plasma levels of proinflammatory cytokines. Activation of the vitamin D receptor expressed on immune cells has been shown to directly reduce the secretion of inflammatory cytokines, such as interleukin-6, and indirectly affect C-reactive protein. Areas of Uncertainty: The significance of the vitamin D pathway in patients diagnosed with COVID-19. Therapeutic Innovation: Vitamin D supplementation in patients after diagnosis of COVID-19. Patients and Pharmacological Interventions: We report 4 vitamin D deficient patients diagnosed with COVID-19 in April 2020 who were provided with either cholecalciferol of 1000 IU daily (standard dose) or ergocalciferol 50,000 IU daily for 5 days (high dose) as part of supplementation. Clinical Outcomes: Patients that received a high dose of vitamin D supplementation achieved normalization of vitamin D levels and improved clinical recovery evidenced by shorter lengths of stay, lower oxygen requirements, and a reduction in inflammatory marker status. Conclusions: Vitamin D supplementation may serve as a viable alternative for curtailing acute respiratory distress syndrome in patients in underserved communities where resources to expensive and sought-after medications may be scarce. Randomized clinical trials will serve as an appropriate vessel to validate the efficacy of the therapeutic regimen and dissection of the pathway.

Abstract
The number of old people is rising worldwide, and advancing age is a major risk factor for atherosclerotic cardiovascular disease. However, the mechanisms underlying this phenomenon remain unclear. In this Review, we discuss vascular intrinsic and extrinsic mechanisms of how ageing influences the pathology of atherosclerosis. First, we focus on factors that are extrinsic to the vasculature. We discuss how ageing affects the development of myeloid cells leading to the expansion of certain myeloid cell clones and induces changes in myeloid cell functions that promote atherosclerosis via inflammation, including a potential role for IL-6. Next, we describe vascular intrinsic factors by which ageing promotes atherogenesis - in particular, the effects on mitochondrial function. Studies in mice and humans have shown that ageing leads to a decline in vascular mitochondrial function and impaired mitophagy. In mice, ageing is associated with an elevation in the levels of the inflammatory cytokine IL-6 in the aorta, which participates in a positive feedback loop with the impaired vascular mitochondrial function to accelerate atherogenesis. We speculate that vascular and myeloid cell ageing synergize, via IL-6 signalling, to accelerate atherosclerosis. Finally, we propose future avenues of clinical investigation and potential therapeutic approaches to reduce the burden of atherosclerosis in old people.

Abstract
Background: Evidence on the cost and risk of infection-related hospitalizations associated with targeted disease-modifying anti-rheumatic drugs (tDMARDs) in patients with RA previously treated with a tumor necrosis factor inhibitor (TNFi) is limited. This study compared the risk and cost of infection-related hospitalizations in commercially insured TNFi-experienced RA patients receiving abatacept, TNFi, or another non-TNFi.Methods: A retrospective observational study was conducted using 2 large insurance claims databases (1 January 2009-30 June 2017). Adult TNFi-experienced RA patients initiating a subsequent tDMARD (initiation date of tDMARD = index date) with 12 months of continuous enrollment pre-index date, and who had ≥1 inpatient or ≥2 outpatient medical RA claims on 2 different dates were included. Abatacept was compared to TNFis (adalimumab, certolizumab pegol, etanercept, golimumab, and infliximab) and other non-TNFis (tocilizumab, rituximab, and tofacitinib). Cox proportional hazards models estimated the adjusted risk for infection-related hospitalization; costs were calculated on a per-member-per-month (PMPM) and per-patient-per-month (PPPM) basis using generalized linear models.Results: More patients in the abatacept cohort had an infection-related hospitalization at baseline (4.5%) vs TNFis (2.0%, p < .0001) and other non-TNFis (3.6%, p = .2619). However, during follow-up abatacept patients had fewer infection-related hospitalizations (abatacept: 2.8%, TNFi: 3.7% and other non-TNFis: 5.2%; p < .05). Regression results indicated that compared to patients on abatacept, patients receiving a TNFi [HR: 1.6 (95% CI: 1.1, 2.2)] and other non-TNFis [HR: 1.9 (95% CI: 1.3, 2.8)] had a significantly higher risk of infection-related hospitalization. Abatacept PMPM costs were lowest ($0.25 vs $0.39 and $0.43 for TNFi and other non-TNFi respectively). Mean PPPM (95% CI) cost in the follow-up was lower for abatacept compared to TNFi ($73 vs. $115; p = .042), and other non-TNFi ($73 vs. $125; p = .039).Conclusions: There were significantly lower infection-related hospitalizations and associated costs in TNF-experienced RA patients treated with abatacept than TNFis and other non-TNFis.

Abstract
BACKGROUND The COVID pandemic has had a major impact on healthcare in hospitals, including the diagnosis and treatment of infections. Hospital-acquired infective endocarditis (HAIE) is a severe complication of medical procedures that has shown a progressive increase in recent years. OBJECTIVES To determine whether the incidence of HAIE during the first two months of the epidemic (March-April 2020) was higher than previously observed and to describe the clinical characteristics of these cases. The probability of the studied event (HAIE) during the study period was calculated by Poisson distribution. RESULTS Four cases of HAIE were diagnosed in our institution during the study period. The incidence of HAIE during the study period was 2/patient-month and 0.3/patient-month during the same calender months in the previous 5 years (p=0.033). Two cases presented during admission for COVID-19 with pulmonary involvement treated with methylprednisolone and tocilizumab. The other two cases were admitted to the hospital during the epidemic. All cases underwent central venous and urinary catheterization during admission. The etiology of HAIE was Enterococcus faecalis (2 cases), Staphylococcus aureus and Candida albicans (one case each). A source of infection was identified in three cases (central venous catheter, peripheral venous catheter, sternal wound infection, respectively). One patient was operated on. Two patients died during hospital admission. CONCLUSIONS The incidence of HAIE during COVID-19 pandemic in our institution was higher than usual. In order to reduce the risk of this serious infection, optimal catheter care and early treatment of every local infection should be prioritized during coronavirus outbreaks.

Abstract
Immune-based therapies such as chimeric antigen receptor (CAR)-T-cell therapy have revolutionized the landscape of cancer treatment in recent years. Although this class of therapy has demonstrated impressive clinical efficacy against cancers that were once thought to be incurable, its success is in part limited by unique toxicities which can be severe or even fatal. Cytokine release syndrome (CRS) is the most commonly observed toxicity and occurs as a result of non-antigen specific immune activation. Similar to macrophage activation syndrome (MAS)/hemophagocytic lymphohistiocytosis (HLH), CRS is associated with elevated levels of several cytokines including interleukin-6 (IL-6) that serve as a driver for host immune dysregulation. As a direct anti-cytokine drug, tocilizumab has been a cornerstone in the treatment of CAR-T-associated CRS through its ability to dampen CRS without compromising CAR-T-cell function. However, optimal timing of administration is yet unknown. Here, we review the use of tocilizumab in the management of CAR-T-associated CRS, emphasizing on the clinical efficacy across various CAR constructs and its role in current CRS management algorithms. We also discuss alternative therapies that may be considered for refractory CRS therapy and the use of tocilizumab in the current COVID-19 global pandemic.

Abstract
Severe acute respiratory syndrome coronavirus 2 is associated with higher concentrations of proinflammatory cytokines that lead to lung damage, respiratory failure, and resultant increased mortality. Immunomodulatory therapy has the potential to inhibit cytokines and quell the immune dysregulation. Controversial data found improved oxygenation after treatment with tocilizumab, an interleukin-6 inhibitor, sparking a wave of interest and resultant clinical trials evaluating immunomodulatory therapies. The purpose of this article is to assess potential proinflammatory targets and review the safety and efficacy of immunomodulatory therapies in managing patients with acute respiratory distress syndrome associated with coronavirus disease 2019.

Abstract
Patients with autoimmune rheumatic diseases (ARD) have an increased risk for tuberculosis (TB). The use of tumor necrosis factor inhibitors (TNFi) and glucocorticoids in these patients has been associated with an increased prevalence of latent TB reactivation. Over the last few years, several biologic disease-modifying anti-rheumatic drugs (bDMARDs), other than TNFi (e.g. rituximab, abatacept, tocilizumab, secukinumab) and targeted synthetic DMARDs (tsDMARDs) [e.g. apremilast, Janus kinase (JAK) inhibitors] have been used for the treatment of patients with ARD. For many of these drugs, especially the newer ones like JAK inhibitors or antibodies against interleukin (IL)-23, most data stem from randomized clinical trials and few are available from real life clinical experience. We sought to review the current evidence for TB risk in patients with ARD treated with tsDMARDs or bDMARDs, other than TNFi. It seems that some of these drugs are associated with a lower TB risk, indirectly compared with TNFi treatment. In fact, it appears that rituximab, apremilast and inhibitors of IL-17 and IL-23 might be safer, while more data are needed for JAK inhibitors. As seen in TNFi, risk for TB is more pronounced in TB-endemic areas. Screening for latent TB must precede initiation of any tsDMARDs or bDMARDs. The growing use of non-TNFi agents has raised the need for more real-life studies that would compare the risk for TB between TNFi and other treatment modalities for ARD. Knowledge about the TB-safety profile of these drugs could help in the decision of drug choice in patients with confirmed latent TB infection or in TB endemic areas.

Abstract
The past 2 decades have seen a revolution in our approach to therapeutic immunosuppression. We have moved from relying on broadly active traditional medications, such as prednisolone or methotrexate, toward more specific agents that often target a single receptor, cytokine, or cell type, using monoclonal antibodies, fusion proteins, or targeted small molecules. This change has transformed the treatment of many conditions, including rheumatoid arthritis, cancers, asthma, and inflammatory bowel disease, but along with the benefits have come risks. Contrary to the hope that these more specific agents would have minimal and predictable infectious sequelae, infectious complications have emerged as a major stumbling block for many of these agents. Furthermore, the growing number and complexity of available biologic agents makes it difficult for clinicians to maintain current knowledge, and most review articles focus on a particular target disease or class of agent. In this article, we review the current state of knowledge about infectious complications of biologic and small molecule immunomodulatory agents, aiming to create a single resource relevant to a broad range of clinicians and researchers. For each of 19 classes of agent, we discuss the mechanism of action, the risk and types of infectious complications, and recommendations for prevention of infection.

Abstract
BACKGROUND Tocilizumab (TCZ), a humanized monoclonal antibody targeting the interleukin-6 (IL-6) receptor, has been proposed for the treatment of COVID-19 patients; however, limited data are available on the safety and efficacy. METHODS We performed a retrospective study on severe COVID-19 patients with hyper-inflammatory features admitted outside intensive care units (ICUs). Patients treated with intravenous TCZ in addition to standard of care were compared to patients treated with standard of care alone. Safety and efficacy were assessed over a 28-day follow-up. RESULTS 65 patients were included. Among them, 32 were treated with TCZ. At baseline, all patients were on high-flow supplemental oxygen and most (78% of TCZ patients and 61% of standard treatment patients) were on non-invasive ventilation. During the 28-day follow-up, 69% of TCZ patients experienced a clinical improvement compared to 61% of standard treatment patients (p = 0.61). Mortality was 15% in the tocilizumab group and 33% in standard treatment group (p = 0.15). In TCZ group, at multivariate analysis, older age was a predictor of death, whereas higher baseline PaO2:FiO2 was a predictor of clinical improvement at day 28. The rate of infection and pulmonary thrombosis was similar between the two groups. CONCLUSIONS At day 28, clinical improvement and mortality were not statistically different between tocilizumab and standard treatment patients in our cohort. Bacterial or fungal infections were recorded in 13% of tocilizumab patients and in 12% of standard treatment patients. Confirmation of efficacy and safety will require ongoing controlled trials.

Abstract
BACKGROUND Mortality of patients with coronavirus disease 2019 (COVID-19), acute respiratory distress syndrome (ARDS), and systemic inflammation is high. In areas of pandemic outbreak, the number of patients can exceed maximum capacity of intensive care units (ICUs), and, thus, these individuals often receive non-invasive ventilation outside of the ICU. Effective treatments for this population are needed urgently. Anakinra is a recombinant interleukin-1 receptor antagonist that might be beneficial in this patient population. METHODS We conducted a retrospective cohort study at the San Raffaele Hospital in Milan, Italy. We included consecutive patients (aged ≥18 years) with COVID-19, moderate-to-severe ARDS, and hyperinflammation (defined as serum C-reactive protein ≥100 mg/L, ferritin ≥900 ng/mL, or both) who were managed with non-invasive ventilation outside of the ICU and who received standard treatment of 200 mg hydroxychloroquine twice a day orally and 400 mg lopinavir with 100 mg ritonavir twice a day orally. We compared survival, mechanical ventilation-free survival, changes in C-reactive protein, respiratory function, and clinical status in a cohort of patients who received additional treatment with anakinra (either 5 mg/kg twice a day intravenously [high dose] or 100 mg twice a day subcutaneously [low dose]) with a retrospective cohort of patients who did not receive anakinra (referred to as the standard treatment group). All outcomes were assessed at 21 days. This study is part of the COVID-19 Biobank study, which is registered with ClinicalTrials.gov, NCT04318366. FINDINGS Between March 17 and March 27, 2020, 29 patients received high-dose intravenous anakinra, non-invasive ventilation, and standard treatment. Between March 10 and March 17, 2020, 16 patients received non-invasive ventilation and standard treatment only and comprised the comparison group for this study. A further seven patients received low-dose subcutaneous anakinra in addition to non-invasive ventilation and standard treatment; however, anakinra treatment was interrupted after 7 days because of a paucity of effects on serum C-reactive protein and clinical status. At 21 days, treatment with high-dose anakinra was associated with reductions in serum C-reactive protein and progressive improvements in respiratory function in 21 (72%) of 29 patients; five (17%) patients were on mechanical ventilation and three (10%) died. In the standard treatment group, eight (50%) of 16 patients showed respiratory improvement at 21 days; one (6%) patient was on mechanical ventilation and seven (44%) died. At 21 days, survival was 90% in the high-dose anakinra group and 56% in the standard treatment group (p=0·009). Mechanical ventilation-free survival was 72% in the anakinra group versus 50% in the standard treatment group (p=0·15). Bacteraemia occurred in four (14%) of 29 patients receiving high-dose anakinra and two (13%) of 16 patients receiving standard treatment. Discontinuation of anakinra was not followed by inflammatory relapses. INTERPRETATION In this retrospective cohort study of patients with COVID-19 and ARDS managed with non-invasive ventilation outside of the ICU, treatment with high-dose anakinra was safe and associated with clinical improvement in 72% of patients. Confirmation of efficacy will require controlled trials. FUNDING None.

Abstract
Introduction: Recent research has shown that IL-6 receptor (IL-6 R) inhibitors like tocilizumab and satralizumab are effective in reducing the relapse rate in patients with NMOSD.Areas covered: This review article explores current concepts in NMOSD management and focuses on IL-6 R as a therapeutic target. The authors delve into the biological and immunological role of IL-6 in the pathogenesis of NMOSD. Further, the authors summarize the most recent findings on the use of anti-IL-6 R monoclonal antibodies, tocilizumab and satralizumab, in the treatment of NMOSD.Expert opinion: A better understanding of the role of cytokines in NMOSD may provide the neurologist with novel therapies for this disease. IL-6 R appears to be a central hub to NMOSD pathogenesis and a relevant therapeutic target.

Abstract
Biologic therapies including monoclonal antibodies, tyrosine kinase inhibitors, and other agents represent a notable expansion in the pharmacotherapy armamentarium in treatment of a variety of diseases. Many of these therapies possess direct or indirect immunosuppressive and immunomodulatory effects, which have been associated with bacterial, viral, and fungal opportunistic infections. Careful screening of baseline risk factors before initiation, targeted preventive measures, and vigilant monitoring while on active biologic therapy mitigate these risks as use of biologics becomes more commonplace. This review compiles reported evidence of fungal infections associated with these agents with a focus on the tumor necrosis factor-α inhibitor class.

Risk of admission to hospital for serious infection after initiating tofacitinib versus biologic DMARDs in patients with rheumatoid arthritis: a multidatabase cohort study. THE LANCET. RHEUMATOLOGY 2020; 2:e84-e98. [PMID: 38263664 DOI: 10.1016/s2665-9913(19)30137-7] [Citation(s) in RCA: 40] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/30/2019] [Revised: 11/26/2019] [Accepted: 11/28/2019] [Indexed: 12/30/2022]
Abstract
BACKGROUND The risk of serious infection is a major concern when prescribing a disease-modifying antirheumatic drug (DMARD) for rheumatoid arthritis. Little evidence exists with regard to serious infection risk associated with tofacitinib, a targeted synthetic (ts)DMARD, compared with biologic DMARDs (bDMARDs) among patients with rheumatoid arthritis. We compared the risk of serious infection in patients with rheumatoid arthritis initiating tofacitinib versus one of the seven bDMARDs. METHODS In this multidatabase cohort study, we identified eight mutually exclusive groups of patients with rheumatoid arthritis initiating tofacitinib or one of the seven bDMARDs using US public (Medicare 20012-15) and private (Optum Clinformatics 2012-18 and IBM MarketScan 2012-17) health insurance programmes. Eligible patients were aged 18 years or older, and had one inpatient visit or two or more outpatient visits (7-365 days apart) for rheumatoid arthritis using International Classification of Diseases 9th and 10th revision codes. The primary outcome was a composite endpoint of admission to hospital for serious infection including bacterial, viral, or opportunistic infection based on the inpatient principal diagnosis code. Secondary outcomes were individual types of serious infections and herpes zoster. We adjusted for more than 60 potential confounders through propensity score-based inverse probability treatment weighting in each database. Database-specific adjusted hazard ratios (aHRs) were combined using a fixed-effects meta-analysis. FINDINGS We identified 130 718 patients with rheumatoid arthritis across the three databases. During 100 790 person-years of follow-up, 3140 serious infections occurred (crude incidence rate per 100 person-years 3·12, 95% CI 3·01-3·23). The aHR for serious infection associated with tofacitinib was 1·41 (95% CI 1·15-1·73) versus etanercept, 1·20 (0·97-1·49) versus abatacept, 1·23 (0·94-1·62) versus golimumab, and 1·17 (0·89-1·53) versus tocilizumab. The serious infection risk with tofacitinib was similar to adalimumab (1·06, 0·87-1·30) and certolizumab (1·02, 0·80-1·29), and was lower than infliximab (0·81, 0·65-1·00). Tofacitinib was associated with a 2-fold higher risk of herpes zoster versus all bDMARDs. INTERPRETATION This study found potential differences between tofacitinib and several bDMARDs in the risk of admission to hospital for serious infection, as well as herpes zoster, in patients with rheumatoid arthritis. These results contribute to the evolving understanding of the overall risk-benefit profile of tofacitinib.

Abstract
Rheumatoid arthritis is a chronic autoimmune disease that is a major public health challenge. The disease is characterised by inflammation of synovial joints and cartilage erosion, which lead to chronic pain, poor life quality and, in some cases, mortality. Understanding the biological mechanisms behind the progression of the disease, as well as developing new methods for quantitative predictions of disease progression in the presence/absence of various therapies is important for the success of therapeutic approaches. The aim of this study is to review various quantitative predictive modelling approaches for understanding rheumatoid arthritis. To this end, we start by briefly discussing the biology of this disease and some current treatment approaches, as well as emphasising some of the open problems in the field. Then, we review various mathematical mechanistic models derived to address some of these open problems. We discuss models that investigate the biological mechanisms behind the progression of the disease, as well as pharmacokinetic and pharmacodynamic models for various drug therapies. Furthermore, we highlight models aimed at optimising the costs of the treatments while taking into consideration the evolution of the disease and potential complications.

Abstract
Infectious diseases always have to be considered in the differential diagnosis of new symptoms in patients with immunosuppressive treatment for established inflammatory rheumatic diseases. Knowledge about the specific frequency and type of infections that can be expected under immunosuppressive treatment of inflammatory rheumatic diseases as well as the diagnostic value of laboratory tests and imaging results can facilitate the often difficult differential diagnosis.

Abstract
Background: Interleukin-6 (IL-6) is a pleiotropic cytokine with a multitude of pro-inflammatory effects. Serum C-reactive protein (CRP) is an acute phase protein induced mainly by IL-6 in response to inflammatory conditions, particularly infection. The biological functions of CRP include opsonisation, induction of phagocytosis, complement activation, or chemotaxis enhancement. Factors interfering with IL-6-mediated recruitment of innate immune responses, such as the presence of anti-IL6 antibodies, may therefore compromise the host resistance to microbial pathogens. This has major implications for the use of IL-6-targeting biologics, such as tocilizumab or sarilumab in rheumatologic, immune dysregulation diseases, and cancer. Case presentation: 20-month-old Czech female developed severe septic shock with clinical and laboratory signs of systemic inflammation but no increase of CRP or IL-6. The offending pathogen was most likely Staphylococcus aureus, detected in a throat swab; the response to antibiotic treatment was prompt. A defect in the integrity of IL-6/CRP axis was suspected and verified by the detection of neutralizing IL-6 antibodies in the serum of the child. Conclusion: We report a first case of systemic bacterial infection in a patient with anti-IL6 autoantibodies. Disturbed IL-6 signaling, whether iatrogenic by targeted IL-6 blockade or endogenous due to the presence of autoantibodies against IL-6, represents a risk factor for increased infectious susceptibility. Patients with severe bacterial infection without elevation of CRP should be examined for the presence of anti-IL6 autoantibodies.

Abstract
Objective To estimate and compare the burdens of opportunistic infections and herpes zoster in real-world practice among patients with various systemic rheumatic diseases. Methods This 13-year cohort study used national health insurance data to compare the incidence rates (IRs) of nine opportunistic infections among patients with five rheumatic diseases. The analyses were stratified according to follow-up duration using Poisson regression, and Cox models were used to compare the risk of first opportunistic infection. Results During 2000–2013, we identified 76,966 patients who had polymyositis/dermatomyositis (PM/DM, 2270 cases), systemic lupus erythematosus (SLE, 15,961 cases), systemic sclerosis (SSc, 2071 cases), rheumatoid arthritis (RA, 38,355 cases), or primary Sjögren’s syndrome (pSS, 18,309 cases). The IR of opportunistic infections was highest for PM/DM cases (61.3/1000 person-years, 95% confidence interval [CI] 56.6–66.2), followed by SLE cases (43.1/1000 person-years, 95% CI 41.7–44.5), SSc cases (31.6/1000 person-years, 95% CI 28.3–35.1), RA cases (25.0/1000 person-years, 95% CI 24.4–25.7), and pSS cases (24.1/1000 person-years, 95% CI 23.1–25.2). Multivariable Cox analysis revealed that, relative to SLE, PM/DM was associated with a significantly higher risk of opportunistic infections (hazard ratio 1.18, 95% CI 1.08–1.29). The risk of opportunistic infections was highest during the first year after the diagnosis of all five rheumatic diseases. Conclusions The risk of opportunistic infection was highest for PM/DM, followed by SLE, SSc, RA, and pSS. Careful observation and preventive therapy for opportunistic infections may be warranted in selected PM/DM patients, especially during the first year after the diagnosis.

Abstract
Interleukin-6 (IL-6) is a pleiotropic cytokine with roles in immunity, tissue regeneration, and metabolism. Rapid production of IL-6 contributes to host defense during infection and tissue injury, but excessive synthesis of IL-6 and dysregulation of IL-6 receptor signaling is involved in disease pathology. Therapeutic agents targeting the IL-6 axis are effective in rheumatoid arthritis, and applications are being extended to other settings of acute and chronic inflammation. Recent studies reveal that selective blockade of different modes of IL-6 receptor signaling has different outcomes on disease pathology, suggesting novel strategies for therapeutic intervention. However, some inflammatory diseases do not seem to respond to IL-6 blockade. Here, we review the current state of IL-6-targeting approaches in the clinic and discuss how to apply the growing understanding of the immunobiology of IL-6 to clinical decisions.

Abstract
(1) Background: Treatment of patients with rheumatoid arthritis (RA) with an anti-IL-6 receptor (anti-IL-6R) monoclonal antibody (tocilizumab) has been found to influence iron metabolism. The objective of the present study was to ascertain whether changes in iron metabolism induced by anti-IL-6R biologic therapy were independently associated with an increased infection risk. (2) Methods: A prospective longitudinal study of patients with RA treated with tocilizumab was conducted. RA patients treated with an antitumor necrosis factor α monoclonal antibody were also included as a control group. The primary outcome was occurrence of infection during the first 24 months of biologic therapy. (3) Results: A total of 15 patients were included, with a mean age of 51.0 ± 4,1 and 73.3% (n = 11) female. A multivariate survival regression model, adjusted for confounding factors, was fitted for each of the iron metabolism variables. Hazard ratios for being above the median of each parameter was considered. Transferrin saturation above the median value (>32.1%) was associated with a higher infection risk (HR 4.3; 95%CI 1.0–19.69; p = 0.05). Similarly, although non-significantly, higher serum iron was strongly associated with infection occurrence. (4) Conclusions: This study identified a probable association between infection risk and higher serum iron and transferrin saturation in patients with RA on anti-IL-6R biologic therapy. We suggest that both these parameters should be considered relevant contributing factors for infection occurrence in patients on anti-IL-6R therapy.
