SARS-CoV-2 infection provoking autoimmunity
For decades, infections have been recognized as strong stimulators of the immune system and subsequently serve as a trigger for autoimmunity and autoimmune diseases. While infection is a very broad term, infectious agents such as bacteria, viruses and parasites, but particularly viruses present a key player in this regard and have been considered a classical example for this correlation
Autoimmune autonomic dysfunction syndromes: Potential involvement and pathophysiology related to complex regional pain syndrome, fibromyalgia, chronic fatigue syndrome, silicone breast implantârelated symptoms and post-COVID syndrome
The pathophysiological mechanisms involved in chronic disorders such as complex regional pain syndrome, fibromyalgia, chronic fatigue syndrome, silicone breast implantârelated symptoms, and post-COVID syndrome have not been clearly defined. The course of the pain in some of the syndromes, the absence of evident tissue damage, and the predominance of alterations in the autonomic nervous system are shared similarities between them. The production of autoantibodies following a trigger in the syndromes was previously described, for instance, trauma in complex regional pain syndrome, infectious agents in fibromyalgia, chronic fatigue syndrome, and post-COVID syndrome, and the immune stimulation by silicone in women with breast implants. In fact, the autoantibodies produced were shown to be directed against the autonomic nervous system receptors, leading to the amplification of the perception of pain alongside various clinical symptoms seen during the clinical course of the syndromes. Therefore, we viewed autoantibodies targeting the autonomic nervous system resulting in autonomic dysfunction as likely the most comprehensive explanation of the pathophysiology of the disorders mentioned. Based on this, we aimed to introduce a new concept uniting complex regional pain syndrome, fibromyalgia, chronic fatigue syndrome, silicone breast implantârelated symptoms, and post-COVID syndrome, namely âautoimmune autonomic dysfunction syndromesâ. Due to its etiological, pathophysiological, and clinical implications, the suggested term would be more precise in classifying the syndromes under one title. The new title would doubtlessly facilitate both laboratory and clinical studies aimed to improve diagnosis and make treatment options more directed and precise
Herpes simplex virus and SLE: Though uncommon yet with significant implications
To the Editor,The relation between infectious agents, particularly viruses, withautoimmunity and autoimmune diseases, has been extensivelystudied during the last decades. Recently, the association was shownto be even stronger during the pandemic of COVIDâ19, as thecausative virus, severe acute respiratory syndrome corona virus2 (SARSâCoVâ2) has been linked to severe autoimmune sequela ininfected individuals. The concerned consequences in patients withCOVIDâ19 were documented during the acute viral infection,throughout the long recovery phase (soâcalled postâCOVID syn-drome), as well as secondary to the vaccines of COVIDâ19.1Actually,the autoimmune nature of SARSâCoVâ2 has been vastly reported inthe medical literature and it is beyond the scope of our currentpaper.2However, it shows the strong bond between infection andautoimmunity. Subsequently, with a deep interest in the field, weanalyzed the article of Chang et al.3concluding that there is nocorrelation between herpes simplex viral infections and systemiclupus erythematosus (SLE) in terms of causality using Mendelian randomization
Social determinants, ethical issues and future challenge of tuberculosis in a pluralistic society: the example of Israel
Tuberculosis is a very serious respiratory infectious disease, caused by the bacillus Mycobacterium tuberculosis, which generates a relevant societal and clinical burden. It has always represented a permanent concern and a public health challenge over the course of human history, because of its severe epidemiological, and economic-financial implications. The present review aims at over-viewing the impact on tuberculosis on the Israeli healthcare system, its temporal trend and evolution, stratified according to ethnicities and minorities, the need of establishing new facilities and implementing screening techniques, public health strategies and diagnostic tests, following massive immigration waves from countries characterized by a high incidence rate of tuberculosis during the fifties-sixties until the nineties, and the policies implemented by the Israeli government in the control, management and treatment of tuberculosis, as well as the role played by Israeli prominent scientists in discovering new druggable targets and finding bioactive compounds and bio-molecules in the fight against tuberculosis. Israel represents a unique, living laboratory in which features of developed and developing countries mix together. This country as a case-study of immigrant, pluralistic society underlines the importance of adopting a culturally-sensitive community intervention approach. The understanding of the subtle interplay between race/ethnic host and pathogen factors, including the role of gene variations and polymorphisms can pave the way for a personalized treatment and management of tuberculosis patients, contributing to the development of new tools for targeted tuberculosis therapeutics, immunodiagnostics and vaccination products
Vaccines and autoimmunityâFrom side effects to ASIA syndrome
Since vaccines are in fact manufactured chemical compounds such as drugs, the appearance of side effects following their use is not surprising. Similarly, as the main goal of vaccines is to stimulate the immune system bringing out the production of protective antibodies, autoimmune-related side effects as a consequence of increased immune activity do not seem irrational. Fortunately, the rate of such side effects is low; however, the importance of reporting adverse events following vaccinations, understanding the mechanisms behind their appearance, making early diagnosis, and appropriate treatment cannot be overemphasized. In fact, autoimmune-related side effects of vaccines, particularly those based on adjuvants, were reported long before the introduction of the autoimmune/inflammatory syndrome induced by adjuvants (ASIA). Nevertheless, ASIA gathered and united the side effects of vaccines under one title, a step which helped organize the research and call for better immune stimulators than adjuvants. New technologies and methods of making vaccines were clearly noticed during the pandemic of COVID-19 after the introduction of mRNA-based vaccines. In our current paper, we introduce the notion of side effects to vaccines, particularly those of autoimmune nature, the mechanisms of ASIA, and the main vaccines linked with the syndrome including the recent COVID-19 vaccines. The transition from side effects to ASIA is the main idea behind our work
Celebrities and medical awarenessâThe case of celine dion and stiff-person syndrome
The positive role of celebrities in spreading important medical information and contributing to increasing public awareness regarding the diagnosis, treatment, and prevention of various medical conditions cannot be overemphasized. Interestingly and importantly at the same time, this impact is not related to the rarity of the disease, as very rare diseases are looked up by the public due to the fact that a celebrity suffers from this disorder. Therefore, if taken seriously and used to address the public in regard to critical medical conditions, such as screening for cancer or the importance of vaccines in fighting infections, celebrities could have a huge impact in this field. As previously shown in the medical literature, the recent announcement of the famous Canadian singer Celine Dion concerning her newly diagnosed stiff-person syndrome has influenced the public interest regarding the syndrome which manifested as an increased search volume related to the disorder as seen in Google Trends. In brief, in this short communication we aimed to address the phenomenon of celebritiesâ impact on public apprehension, revise the syndrome for the medical community, and emphasize taking advantage of such involvement of celebrities for improving the spread of highly important medical information for the public
The COVID-19 pandemic â How many times were we warned before?
Infectious diseases are known to act in both predictable and unpredictable ways, which leads to the notions of emerging and reemerging infectious diseases. Emerging diseases with their disastrous consequences might be surprising and unpredictable, but they could be foreseen. For instance, some emerging diseases and recently the coronavirus disease 2019 (COVID-19) were the reason for papers published by the World Health Organization (WHO) and other researchers addressing the likely pathogens causing future outbreaks, according to the reports of the WHO in 2016 and 2018. Although it might seem like a wisdom in retrospect, several studies had already indicated possible future outbreaks caused by coronaviruses. Announcements, which may be viewed as âwarnings,â appeared since the emergence of the first coronavirus-related outbreak caused by severe acute respiratory syndrome coronavirus (SARS-CoV) in the winter of 2002â2003 and a later outbreak caused by the Middle East respiratory syndrome coronavirus (MERS-CoV) in 2012â2013. Therefore, we were curious to review the medical literature prior to the COVID-19 pandemic with an aim to enumerate and evaluate studies addressing and warning against future outbreaks, and surprisingly pandemics, of members of coronaviruses. Interestingly, we found numerous studies that correctly predicted the current pandemic of COVID-19. While this part is highly interesting, how authorities reacted and prepared for warnings, if any, and how will they get prepared for the next warnings are our main messages. Taking these points into serious consideration will certainly aid in analyzing reports regarding possible future outbreaks as well as in developing various strategies for prevention and coping with such epidemics
Infectious side effects of baricitinib: A big data analysis based on VigiBase
Dear Editor, Baricitinib (known as âOlumiantâ), is an inhibitor of Janus- associated kinase 1 and 2 (JAK1 and JAK2) initially introduced for the treatment of rheumatoid arthritis (RA), and later for systemic lupus erythematosus (SLE), and atopic dermatitis [1]. The first approval of baricitinib was from the European Medicines Agency (EMA) as a mon- otherapy or combination therapy with methotrexate for patients with RA unresponsive to disease-modifying anti-rheumatic drugs (DMARDs
Autoimmune post-COVID vaccine syndromes: Does the spectrum of autoimmune/inflammatory syndrome expand
To date, around 60% of the world population has been protected by vaccines against SARS-CoV-2, significantly reducing the devastating effect of the pandemic and restoring social economic activity through mass vaccination. Multiple studies have demonstrated the effectiveness and safety of vaccines against COVID-19 in healthy populations, in people with risk factors, in people with or without SARS-CoV-2 infection, and in immunocompromised people. According to the criteria for post-vaccine adverse events established by the World Health Organization, a minority of individuals may develop adverse events, including autoimmune syndromes. The exact mechanisms for the development of these autoimmune syndromes are under study, and to date, a cause-effect relationship has not been established. Many of these autoimmune syndromes meet sufficient criteria for the diagnosis of Adjuvant-Induced Autoimmune Syndrome (ASIA syndrome). The descriptions of these autoimmune syndromes open new perspectives to the knowledge of the complex relationship between the host, its immune system, with the new vaccines and the development of new-onset autoimmune syndromes. Fortunately, most of these autoimmune syndromes are easily controlled with steroids and other immunomodulatory medications and are short-lived. Rheumatologists must be alert to the development of these autoimmune syndromes, and investigate the relationship between autoimmune/inflammatory symptoms and vaccination time, and assess their therapeutic response
In response to comment on "Autoimmune post-COVID vaccine syndromes: Does the spectrum of autoimmune/inflammatory syndrome expand?" by Jara LJ et al
We thank Dr. Kunal Chandwar for their interest in our article âAutoimmune post-COVID vaccine syndromes: does the spectrum of autoimmune/infammatory syndrome expand?â Indeed, we have included all of the COVID-19 vaccines, and we agree with you that they have diferent mechanisms of action but similar capabilities to protect against COVID19 to millions of people. Therefore, they also can induce adverse effects, including autoimmune syndromes, in a minority of people with genetic and environmental risk factors
