ABSTRACT

Autoimmune rheumatic diseases (ARD) can affect women and men during fertile age, therefore reproductive health is a priority issue in rheumatology. Many topics need to be considered during preconception counselling: fertility, the impact of disease-related factors on pregnancy outcomes, the influence of pregnancy on disease activity, the compatibility of medications with pregnancy and breastfeeding. Risk stratification and individualized treatment approach elaborated by a multidisciplinary team minimize the risk of adverse pregnancy outcomes (APO). Research has been focused on identifying biomarkers that can be predictive of APO. Specifically, preeclampsia and hypertensive disorders of pregnancy tend to develop more frequently in women with ARD. Placental insufficiency can lead to intrauterine growth restriction and small-for-gestational age newborns. Such APO have been shown to be associated with maternal disease activity in different ARD. Therefore, a key message to be addressed to the woman wishing for a pregnancy and to her family is that treatment with compatible drugs is the best way to ensure maternal and fetal wellbeing. An increasing number of medications have entered the management of ARD, but data about their use in pregnancy and lactation are scarce. More information is needed for most biologic drugs and their biosimilars, and for the so-called small molecules, while there is sufficient evidence to recommend the use of TNF inhibitors if needed for keeping maternal disease under control. Other issues related to the reproductive journey have emerged as "unmet needs", such as sexual dysfunction, contraception, medically assisted reproduction techniques, long-term outcome of children, and they will be addressed in this review paper. Collaborative research has been instrumental to reach current knowledge and the future will bring novel insights thanks to pregnancy registries and prospective studies that have been established in several Countries and to their joint efforts in merging data.

ABSTRACT

The rapid technological advancement over the past few decades has profoundly influenced the scientific approaches that shape the therapeutic landscape. Undoubtedly, immunopharmacology is an important player in the modern era of transition toward precision medicine that is largely defined by the identification of patient-specific therapies. According to the Immunopharmacology Section - ImmuPhar of the International Union of Basic and Clinical Pharmacology (IUPHAR), immunopharmacology is considered to be the youngest area of pharmacology dealing with the selective modulation, mostly up- or down-regulation, of specific immune responses that are often accomplished by immune cell subsets with specialized functions. Although the recent biotechnological progress has made available new classes of drugs with improved selectivity and/or specificity, agents possessing immunomodulating activities have been used in clinical practice for more than 70years. A pertinent example from the late 1940s is the counteraction of the inflammatory response upon administration of cortisone in patients with rheumatoid arthritis. © 2022 Elsevier Inc.

ABSTRACT

Objective: Anxiety and depression are associated with the risk of illness, presence of physical symptoms, and poor health in the COVID-19 epidemic. Our aim is to assess the severity of anxiety and depression in rheumatoid arthritis (RA) patients treated with disease-modifying anti-rheumatic drugs during the COVID-19 pandemic. Material and methods: The study is a longitudinal, hospital-based survey study including 102 RA patients receiving disease-modifying anti-rheumatic drugs with a mean of 55,2±11,9 years. Demographic data, educational status, marital status, employment status, economic status, patients with psychiatric disorders (with the use of prescribed medication for treatment), and medications were recorded. The severity of depression and anxiety were evaluated with the Beck Anxiety and Depression Inventory at the first and second visit of the follow-up during the pandemic period. Results: The mean Beck depression inventory score was found to be higher in the conventional synthetic DMARDs group than in biological DMARDs (12,1±8,2 vs 11,6±9,2, p=0,554). 46 (65,7%) had mild to severe anxiety symptoms in RA patients treated with conventional synthetic DMARDs, on the first visit. There was no significant difference in anxiety and depression status between the first and second visits. The difference in anxiety and depression symptoms between RA patients receiving conventional synthetic and biological DMARDs does not attain statistical significance. Also, no significant differences were found in anxiety and depression scores in the comparisons for gender, education, marital, working, and economic status. Conclusions: The severity of depression and anxiety were higher in RA patients receiving conventional synthetic DMARDs and biological DMARDs during the COVID-19 pandemic. Also, RA patients are likely to experience anxiety and depression during the period of the pandemic.

ABSTRACT

Coronavirus infection can have various degrees of severity and outcomes. In some cases, it causes excessive production of pro-inflammatory cytokines, a so-called cytokine storm, leading to acute respiratory distress syndrome. Unfortunately, the exact pathophysiology and treatment, especially for severe cases of COVID-19, are still uncertain. Results of preliminary studies showed that immunosuppressive therapy, such as interleukin (IL)-6, IL-1, and TNF-α antagonists commonly used in rheumatology, can be considered as treatment options for COVID-19, especially in severe cases. The review focused on the most common and currently studied monoclonal antibody drugs, as well as up-to-date data on the pathogenesis of COVID-19, host immune response against SARS-CoV-2 and its association with cytokine storm. It also covered effects of interleukin (IL)-6, IL-1, and TNF-α blockers on the course of coronavirus infection and outcome in patients treated for the main autoimmune disease and subsequently infected with COVID-19.

ABSTRACT

BACKGROUND: Currently, observations are accumulating indicating the negative effect of therapy with a number of biologic disease-modifying anti-rheumatic drugs (bDMARDs) drugs on the course of COVID-19. These facts determine the relevance of studying the factors of severe course and unfavorable outcome in immuno-inflammatory rheumatic diseases (IIRD) patients treated with bDMARDs in order to develop tactics for managing this category of patients in a pandemic. AIM: To evaluate the influence of clinical and demographic factors on the risk of development, severity of the course and clinical outcomes of a new coronavirus infection in patients suffering from IIRD and receiving therapy with genetically engineered biological drugs. MATERIALS AND METHODS: A retrospective analysis of the database of the register of patients with IIRD receiving bDMARDs in the Novosibirsk region was performed, which included 318 patients, 94 of whom had indications of having suffered viral infection/pneumonia for the period from 01.04.2020 to 31.12.2020. RESULTS: According to the data obtained, at the time of the analysis, 94 people out of 318 patients with IIRD had a new coronavirus infection. Most (53%) of the patients had a mild infection. At the same time, the nosological form, the use of anti-rheumatic drugs and glucocorticoids did not increase the risks of severe coronavirus infection. When using bDMARDs, only anti-B-cell therapy (rituximab) associated with statistically significant increase in the risk of severe/extremely severe COVID-19. The mortality rate according to the analysis of the register was 6,38%. CONCLUSION: Patients with IIRD have a high risk of severe coronavirus infection, while the severity of the disease is associated with the type of therapy performed.

ABSTRACT

BACKGROUND: Autoimmune rheumatic diseases (ARDs) are characterized by immune dysfunction and associated with an increased risk of infections, which were of significant concern during the coronavirus disease 2019 (COVID-19) pandemic. Variable rates of COVID-19 incidence have been reported in patients with ARDs; however, the true effect of this infection on this patient population is still unclear. We, therefore, aimed to evaluate the COVID-19 prevalence among a multiethnic cohort of patients with ARDs in Qatar. MATERIAL AND METHODS: We used telephonic surveys to collect demographic and clinical information of patients with ARD in Qatar between April 1 and July 31, 2020, including any close contact with a COVID-19 case at home or work and polymerase chain reaction (PCR)-confirmed COVID-19 diagnosis. An electronic medical records review was conducted to verify pertinent data collected through the surveys. Prevalence with 95% confidence interval (CI), Student's t-tests, and chi-square/Fisher's exact tests were used for univariate analyses, whereas multivariate logistic regression was used to identify factors associated with COVID-19. RESULTS: The study included 700 patients with ARD (mean age, 43.2 ± 12.3 years), and 73% were female. Until July 2020, 75 (11%, 95% CI 9%-13%) patients had COVID-19. Factors associated with COVID-19 included being a man (adjusted odds ratio [aOR] 2.56, 95% CI 1.35-4.88, p = 0.01) and having close contact with a COVID-19 case (aOR 27.89, 95% CI 14.85-52.38, p = 0.01). Disease severity and rheumatic medications had no significant association with the odds of contracting COVID-19. In the 86 patients with ARD having close contact, the frequency of hydroxychloroquine utilization was lower in patients who contracted COVID-19 than in those who did not (35% vs 72.5%, p = 0.01). CONCLUSIONS: In Qatar, patients with ARDs had an overall higher prevalence of COVID-19 than global estimates. Being male and having close contact with a COVID-19 case were strongly associated with COVID-19 as reported globally. The presence of comorbid conditions, disease-specific factors, and rheumatic medications had no significant effect on the risk of COVID-19 in our study suggesting alternative mechanisms to the increased prevalence.

ABSTRACT

PURPOSE: We aimed to assess the characteristics of inflammatory rheumatic disease (IRD) patients in Kuwait diagnosed with COVID-19 and the factors linked with hospitalization, complications, and mortality. METHODS: Data of IRD patients from Kuwait diagnosed with COVID-19 between March 2020 and March 2021, submitted to the COVID-19 Global Rheumatology Alliance physician-reported registry, were included in our analysis. Data on patients' age, gender, smoking, diagnosis, IRD activity, and other comorbidities were collected. Statistical Package for the Social Sciences (SPSS), version 25, was used for statistical analysis. RESULTS: A total of 52 patients were included, with a mean age of 55 years (±14). The majority of patients were ≤65 years (77%), female (77%), non-smokers (80.8%), and diagnosed with rheumatoid arthritis (67.0%). Of the included patients, 19.2%, 9.6%, and 7.7% reported having methotrexate monotherapy, antimalarials monotherapy, and interleukin-6 inhibitors monotherapy immediately before COVID-19, respectively. Most of the included patients (92.3%) were either in remission or had minimal/low disease activity, while others (7.7%) had moderate disease activity. Forty-three patients (82.7%) were hospitalized, while 11 patients (25.6%) required ventilation (invasive or non-invasive). Ten of the ventilated patients (90.9%) received glucocorticoids as part of the local protocol to treat severe COVID symptoms, and 4 patients (7.69%) died. The duration till symptom-free ranged between 0 to 30 days, with a mean value of 10 days (±6.5). CONCLUSION: The current study provides timely real-world evidence regarding characteristics and potential risk factors linked to poor COVID-19-related outcomes in the IRD population in Kuwait.

ABSTRACT

The clinical and immunological spectrum of acute and post-active COVID-19 syndrome overlaps with criteria used to characterize autoimmune diseases such as rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). Indeed, following SARS-Cov2 infection, the innate immune response is altered with an initial delayed production of interferon type I (IFN-I), while the NF-kappa B and inflammasome pathways are activated. In lung and digestive tissues, an alternative and extrafollicular immune response against SARS-Cov2 takes place with, consequently, an altered humoral and memory T cell response leading to breakdown of tolerance with the emergence of autoantibodies. However, the risk of developing severe COVID-19 among SLE and RA patients did not exceed the general population except in those having pre-existing neutralizing autoantibodies against IFN-I. Treatment discontinuation rather than COVID-19 infection or vaccination increases the risk of developing flares. Last but not least, a limited number of case reports of individuals having developed SLE or RA following COVID-19 infection/vaccination have been reported. Altogether, the SARS-Cov2 pandemic represents an unique opportunity to investigate the dangerous interplay between the immune response against infectious agents and autoimmunity, and to better understand the triggering role of infection as a risk factor in autoimmune and chronic inflammatory disease development.

ABSTRACT

Objectives: Given the high occurrence of asymptomatic subsets, the true prevalence of SARS-CoV-2 infection in rheumatic patients is still underestimated. This study aims to evaluate the seroprevalence of SARS-CoV-2 antibodies in rheumatic musculoskeletal diseases (RMD) patients receiving immunomodulatory drugs. Methods: All consecutive patients with rheumatoid arthritis or spondyloarthritis receiving disease-modifying antirheumatic drugs (DMARDs) evaluated between 4th May and 16th June 2020 were included. All participants were tested for anti-SARS-CoV-2 antibodies (IgG, IgM, IgA) by ELISA and were questioned about previous COVID-19 symptoms and clinical course. Results were compared with healthy population from the same region and with a control group of healthy subjects diagnosed with confirmed COVID-19. Results: The study population includes 358 patients. The overall prevalence of anti-SARS-CoV-2 antibodies (18.4%) was higher than prevalence rate based on swab-positivity (1.12%) or clinically suspected cases (10.6%), but consistent with seroprevalence observed in the healthy population. Among seropositive patients 58% were asymptomatic. Mean anti-SARS-CoV-2 titer was comparable with the control group. No differences in seroprevalence were observed according to age, sex, rheumatic disease and treatment with conventional, biologic or targeted synthetic DMARDs, whereas glucocorticoids and comorbidities resulted in higher seroprevalence rate. Conclusions: The results of this study are reassuring about the low impact of RMDs and immunomodulatory therapies on the risk and clinical course of COVID-19 and on humoral immune response to SARS-CoV-2 infection.

ABSTRACT

Hyperactivation of immune responses resulting in excessive release of pro-inflammatory mediators in alveoli/lung structures is the principal pathological feature of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The cytokine hyperactivation in COVID-19 appears to be similar to those seen in rheumatoid arthritis (RA), an autoimmune disease. Emerging evidence conferred the severity and risk of COVID-19 to RA patients. Amid the evidence of musculoskeletal manifestations involving immune-inflammation-dependent mechanisms and cases of arthralgia and/or myalgia in COVID-19, crosstalk between COVID-19 and RA is often debated. The present article sheds light on the pathological crosstalk between COVID-19 and RA, the risk of RA patients in acquiring SARS-CoV-2 infection, and the aspects of SARS-CoV-2 infection in RA development. We also conferred whether RA can exacerbate COVID-19 outcomes based on available clinical readouts. The mechanistic overlapping in immune-inflammatory features in both COVID-19 and RA was discussed. We showed the emerging links of angiotensin-converting enzyme (ACE)-dependent and macrophage-mediated pathways in both diseases. Moreover, a detailed review of immediate challenges and key recommendations for anti-rheumatic drugs in the COVID-19 setting was presented for better clinical monitoring and management of RA patients. Taken together, the present article summarizes available knowledge on the emerging COVID-19 and RA crosstalk and their mechanistic overlaps, challenges, and therapeutic options.

ABSTRACT

The magnitude of the SARS-CoV-2 pandemic found health systems unprepared, not allowing for prompt evaluation, collaboration among specialities and treatment of severely ill patients admitted to intensive care units, with many of them having an unfortunate outcome. Current data demonstrate an acute immune dysregulation in severe forms of the disease. The above is concluded by clinical evolution and laboratory findings, indicating a severe inflammatory response of the innate immune system, initiating predominately with the involvement of the respiratory tract epithelial cells, occasionally progressing to thrombotic diathesis and related complications. Besides the clinical manifestations, the immune response expresses an extremely high acute phase reactants repertoire including hyperferritinemia, hyper-fibrinogenaemia, and a storm of cytokines that require an alternative view and collaboration with rheumatologists. Thrombotic diathesis in some cases may not attribute only to a possible disseminated intravascular coagulation, but also to an additional activation of adaptive immunity and the development of the antiphospholipid syndrome. Unifying speciality evaluation and treatment may improve patient outcomes by recognizing early the evolving syndromes, treating properly, in a stratifying manner, with medications that alleviate the inflammatory reaction. Corticosteroids, colchicine, hydroxychloroquine/chloroquine, and possibly potent immunosuppressants are in the armamentarium. Additionally, biologics that interrupt the innate immune dysfunction, such as IL-1, IL-6 and selective JAK inhibitors, are also used. Convalescent plasma therapy and human immunoglobulin may be restricted for those whom the proposed treatments are found inadequate. The above combined with antiretroviral medications may improve the outcome until the development of safe and effective vaccination.

ABSTRACT

BACKGROUND: Anti-rheumatic drugs can increase the predisposition to infection, and patients may be unaware of continuing their treatment during the COVID-19 pandemic. OBJECTIVE: This study aimed to assess whether patients maintain their treatment for rheumatic conditions during the pandemic period and determine the factors responsible for discontinuation. METHODS: Patients were randomly selected from the prospectively collected database of our tertiary referral center. The patients were interviewed by telephone through a standardized closed-ended questionnaire, which is targeting the continuity of the treatment plan and the considerations related to the individual choice. The patients were asked whether they hesitated to visit the hospital for follow-up or intravenous drug administration. RESULTS: A total of 278 patients completed the questionnaire. While 62 of the patients (22.3%) had reduced or interrupted the treatment, only 11 patients (3.9%) stopped the treatment completely. A significant difference was observed between the duration of illness and the discontinuation of treatment. (p = 0.023) There was a significant difference in disease activity between the group that stopped treatment and continued treatment. (p = 0.001) There was no statistically significant difference in other demographic characteristics. One hundred thirty-five patients (48.6%) made the treatment decision by themselves, and 80% continued the treatment. Reasons for stopping the treatment were anxiety (48.4%), not being able to go to the hospital for intravenous treatment (45.1%), and not being able to find the drug (6.5%). CONCLUSION: Since patients with long-term illnesses were found to be significantly more likely to stop their treatment, this group of patients should be monitored.

ABSTRACT

BACKGROUND AND OBJECTIVE: Patients with rheumatic disease taking long-term disease-modifying anti-rheumatic drugs (DMARDs) are expected to have a higher risk of infection due to the alterations in cellular immunity associated with these medications. However, the potential risks associated with these drugs remain unclear. This study aimed to estimate the risk of COVID-19 infection in patients with rheumatic disease taking disease-modifying anti-rheumatic drugs. METHODS: Patients with autoimmune rheumatic disease taking DMARDs with or without long-term (> 6 months) HCQ treatment prior to the COVID-19 outbreak were selected consecutively. The diagnosis of COVID-19 was made based on the history of symptoms suggestive of the disease and/or serum IgG positivity. During statistical analysis, the risk of COVID-19 infection was calculated in rheumatic patients taking DMARDs versus controls, as well as in patients taking HCQ versus those who are not. The ORs and 95% CIs were also calculated. The participants in the control group were selected from individuals without RD. RESULTS: A total of 800 patients with RD and 449 controls were analyzed. COVID-19 infection was detected in 16.8% of rheumatic patients versus 17.6% of controls (OR 0.95; 95% CI 0.7-1.28). The proportions of COVID-19 infection in HCQ users versus non-users were 15.3% and 18.1%, respectively (OR 0.87; 95% CI 0.61-1.26). These results remained unchanged after adjusting for all covariates using logistic regression analysis. CONCLUSION: These findings indicate that rheumatic patients taking DMARDs are not at a higher risk of COVID-19 infection, and that HCQ therapy has no influence on the risk of COVID-19 infection. Key points • The risk of COVID-19 infection is not higher in patients with RD on DMARD therapy. • The prevalence of COVID-19 infection in HCQ users has not significant difference relative to non-users. • Significant percent of RD patients taking DMARDs had asymptomatic infection. • There was a positive association between leflunamide therapy and the risk of COVID-19 infection.

ABSTRACT

PURPOSE OF REVIEW: Patients on disease-modifying anti-rheumatic drugs (DMARDs) remain concerned about potential risks of severe COVID-19 outcomes. Meanwhile, several DMARDs have been proposed as COVID-19 therapies. RECENT FINDINGS: In patients with autoimmune diseases, baseline glucocorticoid use is associated with severe COVID-19. While classes of DMARDs (e.g., conventional synthetic, targeted synthetic, and biologic) do not appear to be associated with higher risk, specific medications such as rituximab and sulfasalazine may be associated. Randomized clinical trials (RCTs) show that glucocorticoids reduce mortality in severe COVID-19. RCTs suggest other agents, such as baricitinib, may improve COVID-19 outcomes in certain populations. Baseline glucocorticoid use raises the risk of severe COVID-19 in patients with autoimmune diseases, but glucocorticoids are an effective treatment for those with severe COVID-19. Further research is needed to inform DMARD management in autoimmune disease patients during the pandemic and the role of DMARDs in COVID-19 treatment.

ABSTRACT

Introduction: Coronavirus disease 2019 (COVID-19) pandemic raises a great challenge in the management of patients with rheumatoid arthritis (RA), which are generally more susceptible to infection events because of the autoimmune condition itself and the treatment with immunomodulatory drugs. The use of disease-modifying anti-rheumatic drugs (DMARDs), including biologics and targeted-synthetic DMARDs, has aroused particular interest because of both their immunosuppressive effects and their hypothetical potential in COVID-19 treatment.Areas covered: For this narrative review, a literature search was conducted between December 2019 and February 2021 on PubMed including epidemiological studies, gathering the main evidence available to date about the impact of COVID-19 on RA patients and the influence of anti-rheumatic drugs on patients' susceptibility to this infection. We also summarize the recommendations from the international guidelines on the management of rheumatic diseases and treatments in this pandemic context, especially focused on RA.Expert opinion: About a year after the outbreak of the pandemic, we are able to answer some of the most relevant questions regarding patients with RA and their management in this pandemic context. Our efforts must now be directed toward consolidating the currently available data with more rigorous studies and facing new issues and challenges including, foremost, vaccination.

ABSTRACT

As of June 10th 2020 about 7.2 million individuals have tested positive for, and more than 410,000 have died due to COVID-19. In this review we outline the pathophysiology that underpins the potential use of anti-rheumatic therapies for severe COVID-19 infection and summarize the current evidence regarding the risk and outcome of COVID-19 in patients with systemic autoimmune diseases. Thus far there is no convincing evidence that any disease-modifying anti-rheumatic drug (conventional synthetic, biologic or targeted synthetic) including hydroxychloroquine, may protect against severe COVID-19 infection; answers about their possible usefulness in the management of the cytokine storm associated with severe COVID-9 infection will only arise from ongoing randomized controlled trials. Evidence on COVID-19 risk and outcome in patients with systemic autoimmune diseases is extremely limited; thus, any conclusions would be unsafe and should be seen with great caution. At present, the risk and severity (hospitalization, intensive care unit admission and death) of COVID-19 infection in people with autoimmune diseases do not appear particularly dissimilar to the general population, with the possible exception of hospitalization in patients exposed to high glucocorticoid doses. At this stage it is impossible to draw any conclusions for differences in COVID-19 risk and outcome between different autoimmune diseases and between the various immunomodulatory therapies used for them. More research in the field is obviously required, including as a minimum careful and systematic epidemiology and appropriately controlled clinical trials.

ABSTRACT

Contemporary rheumatology is a field dealing with the phenomena of autoimmune states and inflammation. Rheumatic diseases cover a wide spectrum of diseases of the musculoskeletal system, connective tissue and vessels. The occurrence of an immune, autoimmune and autoinflammatory response is often linked to different kinds of infections. Which aspects of the coronavirus infection relate to rheumatological therapy and practice? In order to answer this question one needs to look at the pathogenesis of the SARS-CoV-2 infection. Antimalarial drugs may block antigen presentation of the viral peptides from antigen presenting cells, as they may alter the lysosomal proteases that mediate the viral entry in the cells and have demonstrated efficacy in improving the infection. Anti-IL-6 may interfere with cytokine storm in severe cases and use of tocilizumab has had good results in a small cohort. Baricitinib not only plays a role in inhibiting the synthesis of cytokines but it also has a function in suppressing receptor-mediated endocytosis. The constantly new and tested concepts in the treatment of COVID testify to the growing knowledge about the virus, but also to the need for more targeted therapy. Treatment regimens have been developed for both patients with COVID-19 and those with symptomatic SARS-CoV infection and rheumatic disease. This article is an attempt to discuss the management of COVID-19 and coexisting rheumatic disease.
