ABSTRACT
In 2011, a syndrome entitled ASIA (Autoimmune/inflammatory Syndrome Induced by Adjuvants; Shoenfeld's syndrome) was first described. ASIA aimed to organize under a single umbrella, the existing evidence regarding certain environmental factors which possess immune stimulatory properties, in order to shed light on a common pathway of autoimmune pathogenesis. Such environmental immune stimulators, or adjuvants, include among others: aluminum salts as in vaccines, various medical implants, as well as various infectious agents. After the launch of the ASIA syndrome, the expansion and recognition of this syndrome by different researchers from different countries began. During the past decades, evidence had been accumulating that (auto)immune symptoms can be triggered by exposure to environmental immune stimulatory factors that act as an adjuvant in genetically susceptible individuals. A panoply of unexplained subjective and autonomic-related symptoms has been reported in patients with ASIA syndrome. The current review summarizes and updates accumulated knowledge from the past decades, describing new adjuvants- (e.g. polypropylene meshes) and vaccine- (e.g. HPV and COVID vaccines) induced ASIA. Furthermore, a direct association between inflammatory/autoimmune diseases with ASIA syndrome, will be discussed. Recent cases will strengthen some of the criteria depicted in ASIA syndrome such as clear improvement of symptoms by the removal of adjuvants (e.g. silicone breast implants) from the body of patients. Finally, we will introduce additional factors to be included in the criteria for ASIA syndrome such as: (1) dysregulated non-classical autoantibodies directed against G-protein coupled receptors (GPCRs) of the autonomic nervous system and (2)) small fiber neuropathy (SFN), both of which might explain, at least in part, the development of 'dysautonomia' reported in many ASIA patients.

OBJECTIVE: The aim of this work is to explore patient' unmet needs of rare and complex rheumatic tissue diseases (rCTDs) patients during pregnancy and its planning by means of the narrative-based medicine (NBM) approach. METHODS: A panel of nine rCTDs patients' representatives was identified to codesign a survey aimed at collecting the stories of rCTD patients who had one or more pregnancies/miscarriages. The results of the survey and the stories collected were analysed and discussed with a panel of patients' representatives to identify unmet needs, challenges and possible strategies to improve the care of rCTD patients. RESULTS: 129 replies were collected, and 112 stories were analysed. Several unmet needs in the management of pregnancy in rCTDs were identified, such as fragmentation of care among different centres, lack of education and awareness on rCTD pregnancies among midwifes, obstetricians and gynaecologists. The lack of receiving appropriate information and education on rCTDs pregnancy was also highlighted by patients and their families. The need for a holistic approach and the availability specialised pregnancy clinics with a multidisciplinary organisation as well as the provision of psychological support during all the phases around pregnancy was considered also a priority. CONCLUSION: The adoption of the NBM approach enabled a direct identification of unmet needs, and a list of possible actions was elaborated to improve the care of rCTD patients and their families in future initiatives.

Injections are widely performed in the healthcare practice. Silicone has long been thought to be an inert and harmless material. Although used for decades in medical implants, including heart valves, breast implants, and as a tamponade for retinal detachment surgery, silicone oil might have deleterious effects. Agitation of the syringe to expel air at the moment of drug preparation not only leads to silicone oil release but also to therapeutic protein aggregation. Lab studies have shown that silicone oil microdroplets can act as an adjuvant to promote a break in immunological tolerance and induce antibody response. Similarly, recent studies have suggested a causal link between agitation of siliconized syringes and ocular inflammation after intravitreal injection. Systemically, silicone oil has been reported in association with autoimmune diseases and skin granuloma after either direct injection of dermal fillers or secondary leakage from silicone breast implant. However, it has not been established yet a potential link between the silicone oil released by the syringes and such relevant systemic adverse events. Few professionals are aware that agitation of a siliconized syringe might lead to silicone oil release, which, in turn, acts an adjuvant to an increased immunogenicity. We strongly recommend that every healthcare professional be aware of the use of silicone oil in the syringe manufacturing process, the factors that promote its release and the potential complications to the organism. Ultimately, we recommend that safer syringes be widely available.
ABSTRACT
INTRODUCTION: Apitherapy - applying the Bee venom to treat medical condition is ancient. According to analysis of google searches, over the past decade there was a steady increase in interest regarding apitherapy. There are some controlled studies alluding to its beneficial effects. There are several anti-inflammatory peptides in the venom, i.e. Melittin, Apamin and more. There are efforts to synthesize them and apply them for therapy. Caution is needed to avoid allergy to bee venom as well as to an anaphylactic shock.

Autoimmune/inflammatory syndrome induced by adjuvants (ASIA) was first introduced in 2011 by Shoenfeld et al. and encompasses a cluster of related immune mediated diseases, which develop among genetically prone individuals as a result of adjuvant agent exposure. Since the recognition of ASIA syndrome, more than 4400 documented cases have been reported so far, illustrated by heterogeneous clinical manifestations and severity. In this review, five enigmatic conditions, including sarcoidosis, Sjögren's syndrome, undifferentiated connective tissue disease, silicone implant incompatibility syndrome (SIIS), and immune-related adverse events (irAEs), are defined as classical examples of ASIA. Certainly, these disorders have been described after an adjuvant stimulus (silicone implantation, drugs, infections, metals, vaccines, etc.) among genetically predisposed individuals (mainly the HLA-DRB1 and PTPN22 gene), which induce an hyperstimulation of the immune system resulting in the production of autoantibodies, eventually leading to the development of autoimmune diseases. Circulating autonomic autoantibodies in the sera of patients with silicone breast implants, as well as anatomopathological aspects of small fiber neuropathy in their skin biopsies have been recently described. To our knowledge, these novel insights serve as a common explanation to the non-specific clinical manifestations reported in patients with ASIA, leading to the redefinition of the ASIA syndrome diagnostic criteria.

An adjuvant is an immunological or pharmacological substance or group of substances that can be added to a given agent to enhance its effect in terms of efficacy, effectiveness and potency. Different mechanisms have been hypothesized underlying the action of the adjuvant, including boosting immune (innate and adaptive) response: this generally results in sparing the necessary amount of the agent and can potentially reduce the frequency of the needed number of therapeutic interventions. Adjuvants can be commonly found in vaccines, immunization products, mineral oils, cosmetics, silicone breast implants and other therapeutic/medical devices, being usually safe and effective. However, in a fraction of genetically susceptible and predisposed subjects, the administration of adjuvants may lead to the insurgence of serious side-effects, called "autoimmune/inflammatory syndrome by adjuvants" (ASIA) or Shoenfeld's syndrome. The present review is aimed at focusing on the "endocrine pebbles" of the mosaic of autoimmunity and of the ASIA syndrome, collecting together 54 cases of sub-acute thyroiditis, 2 cases of Hashimoto's thyroiditis, 11 cases of primary ovarian failure/primary ovarian insufficiency, 13 cases of autoimmune diabetes type 1, and 1 case of autoimmune adrenal gland insufficiency occurred after exposure to adjuvants.

BACKGROUND: We investigated the pattern of reported immune diseases in the international ASIA syndrome registry. METHODS: Data from 500 subjects exposed to adjuvants from the ASIA syndrome international registry were analysed. RESULTS: The patient mean age was 43⯱â¯17â¯years and 89% were female. Within the reported immune diseases, 69% were well-defined immune diseases (autoimmune, autoinflammation, and mixed pattern diseases). Among the well-defined immune diseases following the exposure to adjuvants, polygenic autoimmune diseases were significantly higher than autoinflammatory disorders (92.7% vs 5.8%, respectively, pâ¯<â¯0.001). Polygenic autoimmune diseases such as connective tissue diseases were significantly linked to the exposure to HBV vaccine (OR 3.15 [95%CI 1.08-9.23], pâ¯=â¯0.036). Polygenic autoinflammatory diseases were significantly associated with the exposure to influenza vaccination (OR 10.98 [95%CI 3.81-31.67], pâ¯<â¯0.0001). CONCLUSIONS: Immune conditions following vaccination are rare, and among these, polygenic autoimmune diseases represent the vast majority of the well-defined immune diseases reported under the umbrella ASIA syndrome. However, vaccines benefit outweighs their autoimmune side effects.

A novel small molecule named tuftsin-phosphorylcholine (TPC), which is linked to the biological activity of helminths, was constructed. The current study address the effect of TPC treatment in established collagen-induced arthritis (CIA) mice and propose TPC bi-functional activity. TPC treatment was initiated when clinical score was 2 to 4. Arthritis scores in TPC treated mice were lower compared to mice treated with vehicle (P < 0.001). Joint staining showed normal joint structure in TPC-treated mice compared to control groups treated with phosphate buffered saline (PBS), phosphorylcholine, or tuftsin, which exhibited severely inflamed joints. TPC enhanced anti-inflammatory response due to increased IL-10 secretion, and reduced pro-inflammatory cytokine secretion (IL-1-ß, IL-6, TNF-αP < 0.001). Furthermore, TPC therapy increased expansion of CD4+CD25+FOXP3+T regulatory cells and IL-10+CD5+CD1d+B regulatory cells. We propose that the immunomodulatory activity of TPC can be a result of a bi-specific activity of TPC: (a) The tuftsin part of the TPC shifts RAW macrophage cells from pro-inflammatory macrophages M1 to anti-inflammatory M2-secreting IL-10 (P < 0.001) through neuropilin-1 and (b) TPC significantly reduce mouse TLR4 expression via NFkB pathway by HEKTM cells (P < 0.02) via the phosphorylcholine site of the molecule. Our results indicate that TPC, significantly ameliorated established CIA by its immunomodulatory activity. These data could lead to a novel self bi-functional small molecule for treating patients with progressive RA.

As medical use of cannabis is increasingly legalized worldwide, a better understanding of the medical and hazardous effects of this drug is imperative. The pain associated with rheumatic diseases is considered a prevalent indication for medicinal cannabis in various countries. Thus far, preliminary clinical trials have explored the effects of cannabis on rheumatoid arthritis, osteoarthritis and fibromyalgia; preliminary evidence has also found an association between the cannabinoid system and other rheumatic conditions, including systemic sclerosis and juvenile idiopathic arthritis. The potential medicinal effects of cannabis could be attributable to its influence on the immune system, as it exerts an immunomodulatory effect on various immune cells, including T cells, B cells and macrophages. However, the available evidence is not yet sufficient to support the recommendation of cannabinoid treatment for rheumatic diseases.

The autoimmune/inflammatory syndrome induced by adjuvants (ASIA) is a recently identified condition in which the exposure to an adjuvant leads to an aberrant autoimmune response. We aimed to summarize the results obtained from the ASIA syndrome registry up to December 2016, in a descriptive analysis of 300 cases of ASIA syndrome, with a focus on the adjuvants, the clinical manifestations, and the relationship with other autoimmune diseases. A Web-based registry, based on a multicenter international study, collected clinical and laboratory data in a form of a questionnaire applied to patients with ASIA syndrome. Experts in the disease validated all cases independently. A comparison study regarding type of adjuvants and differences in clinical and laboratory findings was performed. Three hundred patients were analyzed. The mean age at disease onset was 37 years, and the mean duration of time latency between adjuvant stimuli and development of autoimmune conditions was 16.8 months, ranging between 3 days to 5 years. Arthralgia, myalgia, and chronic fatigue were the most frequently reported symptoms. Eighty-nine percent of patients were also diagnosed with another defined rheumatic/autoimmune condition. The most frequent autoimmune disease related to ASIA syndrome was undifferentiated connective tissue disease (UCTD). ASIA syndrome is associated with a high incidence of UCTD and positive anti-nuclear antibodies (ANA) test. Clinical and laboratory features differ from the type of adjuvant used. These findings may contribute to an increased awareness of ASIA syndrome and help physicians to identify patients at a greater risk of autoimmune diseases following the exposure to vaccines and other adjuvants. The ASIA syndrome registry provides a useful tool to systematize this rare condition.

PROBLEM: The purpose of this study was to explore whether vitamin D might be a marker of female primary infertility in association with the presence of autoimmune diseases (ADs). METHODS: The study was a cross-sectional descriptive study in consecutive outpatients of the Polymedical Center for Prevention of Recurrent Spontaneous Abortion (RSA), in Rome, Italy. Women were eligible if they received a diagnosis of primary infertility or RSA. Serum vitamin D, calcium, and PTH were analyzed. RESULTS: Women with primary infertility (n=70) or RSA/non-infertile (n=105) were enrolled; controls (n=250) were included. Infertile women presented lower vitamin D (P=0.03) and higher prevalence of AD (P=0.007) than non-infertile women. In the multivariate analysis, the presence of ADs is associated with higher odds of infertility (OR=2.2), while normal vitamin D was a protective factor (OR=0.9). CONCLUSION: We described that having vitamin D deficiency and suffering from an AD are independent risk factors for women primary infertility. Supplementation of vitamin D might be useful for pregnancy outcome.

Coffee is one of the world's most consumed beverage. In the last decades, coffee consumption has attracted a huge body of research due to its impact on health. Recent scientific evidences showed that coffee intake could be associated with decreased mortality from cardiovascular and neurological diseases, diabetes type II, as well as from endometrial and liver cancer, among others. In this review, on the basis of available data in the literature, we aimed to investigate the association between coffee intake and its influence on the immune system and the insurgence of the most relevant autoimmune diseases. While some studies reported conflicting results, general trends have been identified. Coffee consumption seems to increase the risk of developing rheumatoid arthritis (RA) and type 1 diabetes mellitus (T1DM). By contrast, coffee consumption may exert a protective role against multiple sclerosis, primary sclerosing cholangitis, and ulcerative colitis. Concerning other autoimmune diseases such as systemic lupus erythematosus, psoriasis, primary biliary cholangitis and Crohn's disease, no significant association was found. In other studies, coffee consumption was shown to influence disease course and management options. Coffee intake led to a decrease in insulin sensitivity in T1DM, in methotrexate efficacy in RA, and in levothyroxine absorption in Hashimoto's disease. Further, coffee consumption was associated with cross reactivity with gliadin antibodies in celiac patients. Data on certain autoimmune diseases like systemic sclerosis, Sjögren's syndrome, and Behçet's disease, among others, are lacking in the existent literature. As such, further research is warranted.

PURPOSE OF REVIEW: In recent years, there has been a growing interest in the value of vitamin D and its effects on autoimmunity. The aim of this review is to summarize the current knowledge on the association between vitamin D and rheumatoid arthritis (RA) in terms of prevalence, disease activity, clinical expression, serology and gene polymorphisms of vitamin D receptors. RECENT FINDINGS: Studies have shown contrasting findings concerning the association between vitamin D levels and RA. Vitamin D seems to have immunomodulatory properties. Therefore, low vitamin D levels could contribute to increased immune activation. However, the potential role of vitamin D supplementation in preventing RA manifestation and its beneficial role as a component of RA treatment remain controversial. The relationship between RA susceptibility and vitamin D polymorphisms is also unclear. SUMMARY: Despite advancements synthesized by some recent meta-analyses, the relationship between vitamin D and RA requires further evaluation. Further research is needed to confirm the relationship between RA susceptibility and vitamin D polymorphisms and to determine whether vitamin D plays a role in preventing the manifestation of RA. Finally, additional studies are required to determine the impact and optimal amount of vitamin D supplementation in the treatment of RA patients.

Today, we are facing a new era of digitization in the health care system, and with increased access to health care information has come a growing demand for safe, cost-effective and easy to administer therapies. Dietary habits have a crucial influence on human health, affecting an individual's risk for hypertension, heart disease and stroke, as well as influencing the risk of developing of cancer. Moreover, an individual's lifestyle choices can greatly influence the progression and manifestation of chronic autoimmune rheumatic diseases. In light of these effects, it makes sense that the search for additional therapies to attenuate such diseases would include investigations into lifestyle modifications. When considering the complex web of factors that influence autoimmunity, it is not surprising to find that several dietary elements are involved in disease progression or prevention. In this Review, several common nutritional components of the human diet are presented, and the evidence for their effects on rheumatic diseases is discussed.

Psychological effects related to systemic lupus erythematosus (SLE) are tremendous. While a variety of psychological treatments have been applied to assist SLE patients, the effects of mindfulness practice were never documented in SLE. Mindfulness-based psychotherapy includes several techniques, including body-scan, breathing exercises, and full awareness during daily activities. In this case report, we present a first attempt at conducting mindfulness-based group therapy among SLE patients. Six female SLE patients participated in an 8-week program. Improvement was observed in several areas: patients' increased ability to differentiate between themselves and the disease; increased ability to accept, rather than to actively fight the fact that one must live with the disease; and decreased behavioral avoidance. These observations speak to the significant therapeutic potential of mindfulness practice among SLE patients. With its emphasis on acceptance of negative physical and emotional states, mindfulness practice is a promising treatment option, which needs to be further studied.

Human papillomavirus vaccine (HPVv) is used worldwide for prevention of infection. However several reports link this vaccine, with immune-mediated reactions, especially with neurological manifestations. Our previous results showed that HPVv-Gardasil and aluminum-immunized mice developed behavioral impairments. Studies have shown a positive effect of phospholipid supplementation on depression and cognitive functions in mice. Therefore, our goal was to evaluate the effect of a dietary supplement on vaccine-induced depression. Sixty C57BL/6 female mice were immunized with HPVv-Gardasil, aluminum or the vehicle (n = 20 each group), and half of each group were fed 5 times per week with 0.2 ml of a dietary supplement enriched with phosphatidylcholine. The mice were evaluated for depression at 3 months of age, by the forced swimming test. Both the Gardasil and the aluminum-treated mice developed depressive-like behavior when compared to the control group. The HPVv-Gardasil-immunized mice supplemented with phosphatidylcholine significantly reduced their depressive symptoms. This study confirms our previous studies demonstrating depressive-like behavior in mice vaccinated with HPVv-Gardasil. In addition, it demonstrates the ability of phosphatidylcholine-enriched diet to attenuate depressive-like behavior in the HPVv-Gardasil-vaccinated mice. We suggest that phosphatidylcholine supplementation may serve as a treatment for patients suffering vaccine-related neurological manifestations.

OBJECTIVES: Several reports have indicated an association between systemic lupus erythematosus (SLE) and low levels of vitamin D. We examined several blood work parameters in SLE patients and controls and performed an extensive data analysis in order to investigate the links between blood levels of calcium, vitamin D, and SLE disease. METHODS: 4,278 SLE patients and 16,443 age and sex-matched controls were selected from a national health insurer database in Israel. Patients with no blood work results or having renal disease were excluded. Retrospective data from five consecutive years of routine blood work results were then analysed for mean serum calcium, albumin, albumin-corrected calcium, vitamin D levels, and the presence of a hypocalcaemic episode (Corrected Ca <8.5 mg/dL). RESULTS: The mean levels of corrected serum calcium levels were slightly higher among SLE patients than controls (9.23±0.34 vs. 9.19±0.36 mg/dL p≤.001 respectively). In contrast to results of published studies, SLE patients had slightly higher levels of 25(OH)-vitamin D (SLE patients: 22.2±9.06 ng/ml, controls: 20.0±8.76 ng/ml, p≤.001). The most impressive finding entailing SLE patients was that they were twice as likely to experience episodes of hypocalcaemia in comparison to controls (SLE patients: 13.8%, controls: 6.4%, OR 2.34; 95% CI 2.33-2.83). CONCLUSIONS: Calcium levels may play a significant role in the SLE disease process, more than originally thought, since SLE patients are at a higher risk for hypocalcaemic events. Specific changes in vitamin D and calcium homeostasis in SLE patients may be responsible for the severity of symptoms. Further research is required to determine the role of calcium supplementation.

The autoimmune/inflammatory syndrome induced by adjuvants (ASIA), also known as Shoenfeld's syndrome, encompasses several autoimmune conditions/phenomena that are induced following the exposure to substances with adjuvant activity. The disease spectrum is heterogeneous in respect to clinical presentation as well as severity of the clinical manifestations. Adjuvants are included in vaccination formulations for their immunogenic properties. Despite being generally well tolerated, safe and effective, some genetically predisposed individuals can develop generalized non-specific constitutional symptoms, autoantibody production, new onset, or worsening of disease presentation. In this review, we focus on the current knowledge presented in the literature on ASIA syndrome, increasing physician awareness about the basic concepts of ASIA syndrome and highlight the devastating amount of data accumulated in the last few years concerning the relationship between various adjuvants and autoimmunity.
