RESUMO
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.

Autoimmune/inflammatory syndrome induced by adjuvant (ASIA) includes the following conditions: siliconosis, Gulf War syndrome, macrophagic myofasciitis syndrome, and post-vaccination phenomena. Afterward, other syndromes have been recognized, such as in ASIA by mineral oil (ASIA-MO). These conditions are triggered by adjuvants and they are the result of the interplay of genetic and environmental factors. ASIA-MO is defined as the infiltration of oily type modeling substances for cosmetic purposes. It has been reported in many countries and used surreptitiously. Pathogenesis of ASIA-MO is not clear, but is characterized by chronic granulomatous inflammation, like the pristane model in mice, with increase of proinflammatory cytokines: type I interferons (IFNα and IFNß), systemic lupus erythematosus (SLE), and erosive arthritis. In humans, an increase of interleukin 1 (IL-1) has been found. Clinical spectrum of ASIA-MO is heterogeneous, varying from mild to severe and being local and systemic. The systemic manifestations can be non-specific and specific, meeting criteria for any autoimmune disease (AID), i.e., SLE, rheumatoid arthritis, and systemic sclerosis, among others. The areas of the body where the mineral oil is mostly applied include the following: buttocks (38-72%), breasts (12-16%), lower extremities (18-22%), and face (6-10%). The penis augmentation is also common. Treatment is focused on local and systemic manifestations and requires medical and surgical management representing a challenge for the physician.

Hyperammonemia results from hepatic inability to remove nitrogenous products generated by protein metabolism of intestinal microbiota, which leads to hepatic encephalopathy (HE) in chronic liver disease (CLD). In ammonium neurotoxicity, oxidative stress (OxS) plays a pathogenic role. Our objective was to evaluate if intestinal mannitol is as effective and safe as conventional treatment for diminishing hyperammonemia, OxS, and HE in patients with CLD. MATERIAL AND METHODS: We included 30 patients with HE classified by "Haven Criteria for Hepatic Encephalopathy". They were randomized into two groups: 1) Mannitol Group (MG) with mannitol 20% administered into the intestine by an enema, 2) conventional group (CG) with lactulose 40â¯g enema both substances were diluted in 800â¯mL of double distilled solution every 6â¯h; all patients received neomycin. We evaluated ammonia concentration, plasma oxidative stress, HE severity, intestinal discomfort and adverse effects. RESULTS: Hyperammonemia (171⯱â¯104 vs 79⯱â¯49⯵mol ammonia/L, pâ¯<â¯0.01), and oxidative stress (MDA 29 vs 27%, formazan 15 vs 11%, carbonyls 16 vs 9% and dityrosines 10 vs 5%) were reduced in MG and CG respectively. The HE severity decreased by two degrees compared to baseline values in both groups. Intestinal discomfort and electrolyte plasma alterations were less frequent (pâ¯<â¯0.05) in MG than CG. CONCLUSIONS: Intestinal mannitol is as effective and safe as conventional treatment for reducing hyperammonemia, oxidative stress, and hepatic encephalopathy of CLD patients in the emergency room. Likewise, mannitol is better tolerated than conventional treatment.

Calcinosis is a frequent complication of systemic sclerosis (SSc) that is usually located in extremities but may occur across the board. The aim of our study was to identify and quantify the distribution of calcinosis in a cohort of Mexican patients with SSc and its association with clinical features and autoantibodies. A cohort of patients with SSc (2013 ACR/EULAR criteria), classified in diffuse cutaneous (dcSSc) and limited cutaneous (lcSSc) (Le Roy criteria), was studied. For their analysis, patients were allocated into those with and without calcinosis (clinical and/or radiological). The evaluation included the modified Rodnan scale for skin and Medsger disease severity scale (DSS). Calcium, phosphorus, vitamin D, and parathyroid hormone (PTH) and antinuclear antibodies and extractable nuclear antigens were determined in serum. A total of 109 patients were included, 41 (37 %) with and 68 (63 %) without calcinosis. Calcinosis was more frequent in patients with dcSSc (55 vs 27 %). In total, we identified 354 sites with calcinosis and mean per patient of 12.0 ± 9.1; the most common sites affected were the hands (83 %), proximal upper extremity (27 %), and proximal lower extremity (22 %). Patients with calcinosis had a higher score of Rodnan scale, Mesdger DSS, and frequency of anti-nucleolar and anti-Scl-70 antibodies compared to those without calcinosis. Abnormal PTH elevation was found in 35 % of patients with calcinosis and 23 % without it. The prevalence of calcinosis is high in Mexican patients with SSc, especially in diffuse variety, and is associated with increased severity of disease.

Autoimmune/inflammatory syndrome induced by adjuvants (ASIA) encompassing conditions linked to previous exposure to an adjuvant substance. The clinical picture is very heterogeneous, from mild to severe manifestations, including death. However, the systematic analysis of severe ASIA cases has not been performed. The aim of this study was to systematically review the literature on severe ASIA cases. A systematic review of the literature was performed investigating severe ASIA cases. All publications were identified through PubMed, EMBASE, MEDLINE and Cochrane. Articles published from 2011 to 2016 were included. Severe ASIA was arbitrarily defined as follows: major organ involvement, life-threatening conditions, intensive treatment, disability, hospitalization and outcome (survival and death). Cases described before 2011 were excluded. From 2011 to 2016, we identified 4479 ASIA cases, of them 305 fulfilled arbitrary criteria of severe ASIA including our case presentation and 11 deaths. The majority of severe ASIA cases were related to HPV vaccine, silicone, influenza vaccine and mineral oil injections. The interval from exposition to severe manifestation was from 2 days to 23 years. (1) This is the first study that analyzes all cases published on ASIA with severe manifestations. (2) The current HPV vaccine is both effective and generally safe. However, it should be noted that severe autoimmune side effects have been reported in several studies. Severe ASIA may be observed after influenza vaccines, and other vaccines. (3) Efforts should be made to discover the connection between adjuvants, autoimmunity and autoimmune diseases, because there is an increase in cases severe and life-threatening of ASIA.

An adjuvant is a substance that enhances the antigen-specific immune response, induces the release of inflammatory cytokines, and interacts with Toll-like receptors and the NALP3 inflammasome. The immunological consequence of these actions is to stimulate the innate and adaptive immune response. The activation of the immune system by adjuvants, a desirable effect, could trigger manifestations of autoimmunity or autoimmune disease. Recently, a new syndrome was introduced, autoimmune/inflammatory syndrome induced by adjuvants (ASIA), that includes postvaccination phenomena, macrophagic myofasciitis, Gulf War syndrome and siliconosis. This syndrome is characterized by nonspecific and specific manifestations of autoimmune disease. The main substances associated with ASIA are squalene (Gulf War syndrome), aluminum hydroxide (postvaccination phenomena, macrophagic myofasciitis) and silicone with siliconosis. Mineral oil, guaiacol and iodine gadital are also associated with ASIA. The following review describes the wide clinical spectrum and pathogenesis of ASIA including defined autoimmune diseases and nonspecific autoimmune manifestations, as well as the outlook of future research in this field.
