The ASIA syndrome: basic concepts

The Diagnosis and Management of Patients With Findings Consistent With a Breast Implant Associated-Somatic Symptom Disorder (BIA-SSD)

Background

Psychological factors seem to play a significant role in the perception and magnification of somatic symptoms in patients with breast implant illness (BII). Further, recent studies have shown that some patients with self-reported BII have findings consistent with a breast implant-associated somatic symptom disorder (BIA-SSD). The aim of this work was to provide guidelines for the diagnosis and treatment of BIA-SSD.

Methods

Findings from the current literature combined with both surgical and psychological therapeutic principles were used to develop methods for diagnosing and managing patients with BIA-SSD.

Results

Algorithms for the diagnosis of SSD associated with breast implants, as well as treatment options, are presented so that plastic surgeons can identify, counsel, diagnose, and offer treatment to patients with BII and findings consistent with BIA-SSD.

Conclusions

Plastic surgeons are in a unique position to identify self-reported BII patients with signs of BIA-SSD and offer help in navigating treatment options. In addition to providing information to patients about somatic symptoms and breast implants, surgeons should refer patients for a medical workup to rule out medical causes of symptoms. For patients with symptoms and a desire to maintain breast implants, referral to a qualified mental health professional trained in SSD therapy may be beneficial. For patients desiring removal of their implants for BII symptoms, explantation with the most conservative possible procedure is recommended.

Role of NLRP3 inflammasome in nanoparticle adjuvant-mediated immune response

The nucleotide-binding oligomerization domain (NOD)-like receptor (NLR) family pyrin domain-containing 3 (NLRP3) inflammasome is pivotal in orchestrating the immune response induced by nanoparticle adjuvants. Understanding the intricate mechanisms underlying the activation of NLRP3 inflammasome by these adjuvants is crucial for deciphering their immunomodulatory properties. This review explores the involvement of the NLRP3 inflammasome in mediating immune responses triggered by nanoparticle adjuvants. It delves into the signaling pathways and cellular mechanisms involved in NLRP3 activation, highlighting its significance in modulating the efficacy and safety of nanoparticle-based adjuvants. A comprehensive grasp of the interplay between NLRP3 inflammasome and nanoparticle adjuvants holds promise for optimizing vaccine design and advancing immunotherapeutic strategies.

Innate immune training of osteoclastogenesis promotes inflammatory bone loss in mice

We previously demonstrated that long-term trained immunity (TRIM) involves adaptations that imprint innate immune memory in long-lived myelopoiesis precursors and their progeny, monocytes/macrophages and neutrophils, which thereby acquire enhanced responsiveness to future challenges. Here, we show that a distinct component of myeloid biology, osteoclastogenesis, can also undergo innate immune training. Indeed, β-glucan-induced TRIM was associated with an increased osteoclastogenesis bias in the bone marrow and an expansion of monocytes/osteoclast progenitors in the periphery, resulting in aggravated severity of experimental periodontitis and arthritis. In the setting of trained inflammatory osteoclastogenesis, we observed transcriptomic rewiring in synovial myeloid cells of arthritic mice, featuring prominent upregulation of the transcription factor melanogenesis-associated transcription factor (MITF). Adoptive transfer of splenic monocytes from β-glucan-trained mice to naive recipients exacerbated arthritis in the latter in a strictly MITF-dependent manner. Our findings establish trained osteoclastogenesis as a maladaptive component of TRIM and potentially provide therapeutic targets in inflammatory bone loss disorders.

Autoimmune/Inflammatory Syndrome Induced by Adjuvants (ASIA) after Silicone Breast Implants

Autoimmune/inflammatory syndrome is a complex condition characterized by various autoimmune and inflammatory symptoms following the exposure to an adjuvant such as silicone. Autoimmune/inflammatory syndrome induced by adjuvants (ASIA) is challenging to diagnose because it can mimic other autoimmune diseases and requires specific criteria for identification. We report a case of a 35-year-old woman who developed inflammatory joint pain, fatigue and myalgia after receiving silicone breast implants. Symptoms improved significantly after administration of steroids. Based on the fulfilment of the ASIA diagnostic criteria, the diagnosis was made. This case emphasizes the importance of understanding this condition in patients with unexplained systemic symptoms after exposure to adjuvants.

LEARNING POINTS

Autoimmune/inflammatory syndrome induced by adjuvants (ASIA) should be considered in patients with unexplained systemic symptoms following exposure to adjuvants.Steroids can offer significant symptom relief; however, implant removal may be necessary if symptoms persist or recur.Awareness of ASIA can help in early diagnosis, and in improving patient outcomes.

Artificial intelligence meets the world experts; updates and novel therapies in autoimmunity - The 14th international congress on autoimmunity 2024 (AUTO14), Ljubljana

The bi-annual international congress on autoimmunity is a huge opportunity for the medical community to discuss the latest updates in the field. During the 14th congress 2024 (AUTO14) in Ljubljana, artificial intelligence (AI) occupied special attention due to its recent and ongoing unequivocal role in various medical fields including autoimmunity. For instance, through a challenging debate between world-experts and the most popular AI bot used (ChatGPT), several clinical cases including a case of vasculitis were discussed in the plenary sessions. ChatGPT agreed with the clinical decisions made by the experts nevertheless, the bot added additional aspects related to the specific case. In this regard, ChatGPT emphasized the need for osteoporosis prophylaxis in a patient planned to be treated with systemic steroids for a long time. Furthermore, AUTO14 included the newest updates on most autoimmune disorders, distributed among tens of sessions. Among others, infection and autoimmunity, the sequalae of the pandemic of COVID-19, as well as COVID-19 vaccines were discussed as well. Due to the high numbers of the works presented, and for ensuring that important updates are not missed; we divided our paper into sections. The subtitles throughout the paper correspond to different sessions of the congress, all presenting new updates in the field. A figure aiding in navigating throughout the paper was also provided.

Adverse effects of the aesthetic use of botulinum toxin and dermal fillers on the face: a narrative review

OBJECTIVE

To evaluate the adverse effects of facial aesthetic treatments using botulinum toxin and biomaterial implants.

METHODS

The bibliographic research for this narrative review considered articles published in journals from the Medline, Pubmed, Embase and Lilacs databases with the following terms: "dermal fillers AND complications, vascular complications AND dermal fillers, adverse reaction, AND toxin botulinum and adverse reaction AND dermal fillers". Inclusion criteria were articles available in English on adverse events with the aesthetic use of botulinum toxin and dermal fillers/biostimulators.

RESULTS

The demonstration of complications increases simultaneously with the progressive performance of facial aesthetic procedures. Quantitative statistics of the procedures and the countries that use them are skillfully classified, as well as the prosperity trends of these procedures. Complications do not receive the same relevance. There is a deficiency in dissemination of the information by the scientific community, or in other words, there is a publication bias in favor of successful results as opposed to adverse events.

CONCLUSION

The lack of knowledge about complications arising from so widely publicized and performed procedures prevents the development of evidence-based guidelines. Complications in aesthetic procedures have become a public health problem, an epidemic that occurs under the supervision of health authorities. Mandatory reporting of adverse events occurring in aesthetic procedures that require medical care aims to fill this gap. With reliable and technical data, it will be possible to identify the causes and perform interventions capable of minimizing irreversible sequelae and deaths. Complications should be promptly recognized by the dermatologist so that, when possible, they can be reversed or adequately managed.

Autoimmune/inflammatory syndrome induced by adjuvants (ASIA) from 2011 to 2024: A comprehensive bibliometric review

INTRODUCTION

Autoimmune/Inflammatory Syndrome Induced by Adjuvants (ASIA) encompasses a spectrum of autoimmune and inflammatory conditions triggered by various adjuvants, leading to significant health challenges. This study aims to understand the research landscape and future directions of ASIA through a comprehensive bibliometric analysis.

METHODS

Relevant original articles were retrieved from the Scopus database, focusing on publications from 2011 to July 2024. The analysis included evaluating countries/regions, institutions, authors, co-cited references, and keywords using VOSviewer and Biblioshiny software.

RESULTS

The final analysis incorporated 346 documents contributed by numerous researchers from multiple institutions worldwide. Israel emerged as the leading contributor to ASIA research. The study found that while there are significant international collaborations, certain countries like Israel and Italy play central roles in these networks. Key research areas identified include autoimmunity, adjuvants, vaccines, and silicone. Notable keywords include "ASIA syndrome," "Autoimmunity," "Adjuvants," and "Silicone." The citation analysis highlighted the impactful nature of research from Israel, Italy, and Mexico. In addition, the analysis highlights the growing body of evidence that supports the role of adjuvants in triggering autoimmune responses. Over the years, there has been a significant increase in publications investigating the mechanisms by which adjuvants (such as those used in vaccines, silicone implants, and other medical applications) can activate immune responses, leading to conditions associated with ASIA syndrome.

CONCLUSION

The field of ASIA research is experiencing rapid growth, characterized by increasing publication activity and robust international collaborations. Future research is likely to focus on the mechanisms underlying ASIA syndrome and improving patient outcomes.

Pituitary and COVID-19 vaccination: a systematic review

PURPOSE

This systematic review aims to examine the latest research findings and assess the impact of COVID-19 vaccination on the pituitary gland.

METHOD

PubMed and Tripdatabase were searched from January 1st, 2020 to February 12th, 2024. Case reports, case series and reviews related to post COVID-19 vaccination pituitary disease were included. Eligible articles were tabulated and analysed in the attempt to provide an overview on the epidemiology, clinical presentation, imaging, treatment, outcomes and pathophysiological background of post COVID-19 vaccination pituitary disease.

RESULTS

Among the 23 case reports included in this review, post COVID-19 vaccination hypophysitis was reported in 9 patients, pituitary apoplexy (PA) in 6 cases, SIADH in 5 cases and Isolated ACTH deficiency in 2 cases. Additionally, precipitating adrenal crisis was registered in 7 patients and pituitary tumor enlargement in 1 patient after receiving COVID-19 vaccination.

CONCLUSION

Despite the rarity of these events, our research findings suggest an association between COVID-19 vaccination and the subsequent development of pituitary diseases. The most common manifestations include hypophysitis with ADH deficiency, PA and SIADH, with symptoms typically emerging shortly after vaccine administration. Potential pathogenetic mechanisms include molecular mimicry, vaccine adjuvants and vaccine-induced thrombotic thrombocytopenia (VITT), with the presence of ACE2 receptors in the hypothalamus-pituitary system contributing to the process. These findings can aid in diagnostic and treatment decisions for patients presenting with these syndromes. Nevertheless, given the rarity of these events, safety and efficacy of the currently available COVID-19 vaccines remain robust and we strongly advocate continuing pursuing vaccination efforts.

Immune thrombocytopenia (ITP) - could it be part of autoimmune/inflammatory syndrome induced by adjuvants (ASIA)?

Immune thrombocytopenia (ITP) is a complex autoimmune disorder characterized by thrombocytopenia and an increased bleeding risk, arising from autoantibody-mediated platelet destruction and impaired megakaryocyte function. The pathogenesis of ITP involves a multifaceted interplay of genetic predispositions, immune dysregulation, and environmental triggers, though the precise mechanisms remain uncertain. Several infectious agents, mostly viruses, have been implicated in both acute and chronic ITP through mechanisms such as molecular mimicry, direct bone marrow suppression, and immune dysregulation. Vaccinations, particularly those containing adjuvants like aluminum and those capable of inducing molecular mimicry, have also been associated with ITP, either as a new onset or as a relapse in preexisting cases. The role of drugs, particularly quinine, quinidine and certain antibiotics, in inducing ITP through various immunological pathways further illustrates the diverse etiologies of this condition. The multiple triggers of the disease raise the question of whether ITP may be classified as an autoimmune/inflammatory syndrome induced by adjuvants (ASIA). This condition encompasses a range of autoimmune and inflammatory symptoms triggered by adjuvants, such as silicones, polypropylene meshes, metal implants, and mineral oils present in various medical materials and medications. Similar to that observed in some cases of ITP, adjuvants can trigger autoimmune or autoinflammatory responses via molecular mimicry, epitope spreading, and polyclonal activation. This narrative review explores the underlying environmental factors related to ITP and examines ITP triggers that could potentially support an association between ITP and ASIA syndrome.

New Onset of Neuro-Sjögren's Syndrome Nine Months After the Third COVID-19 Vaccine Dose: A Case Report

Sjögren's syndrome (SS) is an autoimmune chronic inflammatory disease causing peripheral nerve system and central nervous system issues. It results from lymphocytic infiltrates in exocrine glands, coexists with rheumatoid arthritis, and manifests independently. The COVID-19 vaccine has been linked to increased autoimmune diseases and rheumatological flare-ups, possibly due to its use of adjuvants and molecular mimicry, particularly those containing aluminum. Additionally, SS-like manifestations have been reported after the infection or vaccination, potentially leading to long-term salivary secretory dysfunction. Multiple studies have suggested the presence of a special relationship between COVID-19 vaccination/infection and the emergence of autoimmune syndromes as a negative side effect of the vaccine or direct complication from infection. The time frame for the appearance of the symptoms after vaccination or disease is not well established. Some studies suggested increased risk shortly after vaccination, while others suggested a long-term association. In this case, report, and review article, we discuss the presence of a possible association with the emergence of neuro-SS in a young lady nine months after she received her third dose of COVID-19 vaccination. Furthermore, we reviewed studies highlighting the special link and relationship between the COVID-19 vaccine/infection and SS.

The Problem of Diagnostic Criteria of Breast Implant Illness in Women After Breast Reconstruction: Review and Discussion of a Case

INTRODUCTION

There has been a rising trend in the use of silicone breast implants for breast reconstructions after breast cancer treatment, as well as in the aesthetic breast procedures. A cluster of non-specific symptoms related to the presence of silicone implant has been called breast implant illness (BII). However, there are no strict criteria of BII which would specifically define this term. The increasing interest in BII among patients and physicians urges verifying own cases of "on-demand" explantations.

MATERIAL AND METHODS

In this paper, we discussed a case of a patient with initial BII diagnosis, after breast reconstruction, and reviewed the literature on the BII symptoms and aetiology. A decision for aesthetic revision, not explantation, was made as the diagnosis of BII was questioned, and somatisation due to dissatisfaction with the aesthetic result of breast reconstruction was diagnosed.

RESULTS

Improving aesthetics by implant exchange and contralateral mastopexy caused a full recovery from patient's symptoms.

CONCLUSION

Based on our case, we point on the fact that BII diagnosis in patients after breast reconstruction is challenging. We suggest that while considering such a diagnosis and further proceedings, e.g. explantation, especially in patients after breast reconstruction, some exclusion criteria should be considered. Dissatisfaction with the result of the surgery can also lead to somatisation and the presence of real clinical symptoms, which should not be confused with the possible autoimmune reaction to silicone particles.

Adjuvant-Induced Autoimmune Syndrome: A Bibliometric Analysis

The autoimmune/inflammatory syndrome induced by adjuvants (ASIA) encompasses various autoimmune conditions triggered by exposure to substances with adjuvant activity. Despite its potential relevance to public health, global scientific production on ASIA syndrome is significantly limited. This knowledge gap underscores the need for a comprehensive bibliometric assessment to understand global research in this field. Therefore, this article aims to conduct a bibliometric analysis to identify and evaluate research trends related to ASIA syndrome worldwide. A Scopus search identified scientific documents published between 2010 and 2022. A total of 2,133 articles meeting inclusion criteria were selected and analyzed for scientific production, authors, and institutions. Two-hundred fifty six documents were analyzed, mostly journal articles with multiple authors. The year with the highest publications was 2023, marking a notable increase since 2021. Italy and Israel had the most documents and citations, correlating with authors Yehuda Shoenfeld (Israel) and Carlo Perricone (Italy). Standout journals are "The Journal of Immunologic Research" and "Lupus." Relevant affiliations include Tel-Aviv University and the National Autonomous University of Mexico. This article identifies and analyzes scientific trends associated with ASIA syndrome. Despite increased publications, this field remains controversial and lacks full acceptance within the medical and scientific community, as evidenced by limited scientific production compared to other pathologies. These findings may motivate researchers to generate impactful publications, contributing to the global knowledge expansion on this syndrome.

Type 1 diabetes mellitus following COVID-19 vaccination: a report of two cases and review of literature

Severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) infection, which led to the coronavirus 2019 (COVID-19) pandemic, has promoted the development of novel therapeutic agents and vaccines to combat the global spread of the virus. While the COVID-19 vaccines approved thus far have proven to be effective in clinical settings, there have been reports of autoimmune diseases occurring following vaccination, including autoimmune/inflammatory syndrome induced by adjuvant syndrome. We herein report two cases of type 1 diabetes mellitus that occurred following COVID-19 vaccination and provide a literature review. Both cases received multiple vaccinations as recommended to ensure optimal antibody titers. Moreover, the HLA associated with susceptibility to type 1 diabetes was prototypic in both cases. This indirect evidence suggests that the COVID-19 vaccines may be implicated in the pathogenesis of type 1 diabetes. Further case reports to establish a clearer understanding of a potential association are warranted.

Foreign substance injection for esthetic purposes associated with delayed unilateral sciatic nerve impairment: A surgical case report

Attempts at body contour modifications have led to the use of different alloplastic materials that can irreversibly damage health and risk patients' lives. These modeling substances can induce a general autoimmune inflammatory response, producing a very heterogeneous clinical spectrum ranging from mild and severe systemic to local symptoms that sometimes affect peripheral nerves. We report a unique case of a tumor-like sciatic nerve impairment produced months after the injection of a modeling substance into the buttocks for esthetic purposes. The patient was treated with a surgical decompression of the sciatic nerve that encompassed the removal of the injected mass. This approach ultimately yielded a complete neurological recovery of the affected nerve. We emphasize the diagnostic approach and surgical management employed in this unique case and review the current literature on this infrequent complication.

The Autoimmune/Inflammatory Syndrome Induced by Adjuvants (ASIA), Associated with Renal Compromise and Cutaneous Calcinosis: A Case Report and Literature Review

The autoimmune/inflammatory syndrome induced by adjuvants (ASIA) was first introduced in 2011 to provide a more precise syndromic characterization of clinical manifestations observed in patients exposed to adjuvant substances such as biopolymers and silicone, among others. The clinical spectrum of this entity is variable, ranging from local involvement to potentially fatal immune-mediated systemic involvement. The interest in ASIA has grown in recent years, reinforcing diagnostic criteria and deepening the understanding of its pathophysiological behavior. This case report highlights a distinct range of clinical symptoms, such as general symptoms, advanced-stage chronic kidney disease, persistent hypercalcemia with suppressed parathyroid hormone (PTH), bilateral nephrocalcinosis, cutaneous calcinosis, and the presence of positive autoantibodies, emphasizing the significance of understanding this condition.

Adjuvants in cutaneous vaccination: A comprehensive analysis

Skin is the body's largest organ and serves as a protective barrier from physical, thermal, and mechanical environmental challenges. Alongside, the skin hosts key immune system players, such as the professional antigen-presenting cells (APCs) like the Langerhans cells in the epidermis and circulating macrophages in the blood. Further, the literature supports that the APCs can be activated by antigen or vaccine delivery via multiple routes of administration through the skin. Once activated, the stimulated APCs drain to the associated lymph nodes and gain access to the lymphatic system. This further allows the APCs to engage with the adaptive immune system and activate cellular and humoral immune responses. Thus, vaccine delivery via skin offers advantages such as reliable antigen delivery, superior immunogenicity, and convenient delivery. Several preclinical and clinical studies have demonstrated the significance of vaccine delivery using various routes of administration via skin. However, such vaccines often employ adjuvant/(s), along with the antigen of interest. Adjuvants augment the immune response to a vaccine antigen and improve the therapeutic efficacy. Due to these reasons, adjuvants have been successfully used with infectious disease vaccines, cancer immunotherapy, and immune-mediated diseases. To capture these developments, this review will summarize preclinical and clinical study results of vaccine delivery via skin in the presence of adjuvants. A focused discussion regarding the FDA-approved adjuvants will address the experiences of using such adjuvant-containing vaccines. In addition, the challenges and regulatory concerns with these adjuvants will be discussed. Finally, the review will share the prospects of adjuvant-containing vaccines delivered via skin.

Subacute thyroiditis after SARS-CoV-2 vaccination: A case report

Key Clinical Message

Subacute thyroiditis which is typically characterized by cervical pain and fever is caused by viral infection and is seen after SARS-CoV-2 vaccination. Here we report a post-vaccination subacute thyroiditis after SARS-CoV-2 vaccination.

Abstract

Subacute thyroiditis (SAT) is possibly caused by a viral infection and is typically characterized by cervical pain and fever. SAT associated with SARS-CoV-2 infection or SARS-CoV-2 vaccination has been reported, albeit in limited numbers. A 34-year-old woman was referred to our clinic with typical SAT symptoms. The diagnosis was confirmed through thyroid scintigraphy after receiving the SARS-CoV-2 vaccination, despite testing negative for COVID-19 via RT-PCR. There is a theoretical correlation between SARS-CoV-2 vaccination and SAT. Vaccination may have a direct or indirect impact on the thyroid, but further studies are required to confirm this relationship. A systematic review of the literature of similar cases was performed for comparison. Ultimately, the overall benefits of SARS-CoV-2 vaccination outweigh the potential adverse effects. Therefore, these types of reports should not divert attention from the actual reality.

Assessment of mesh shrinkage using fibroblast-populated collagen matrices: a proof of concept for in vitro hernia mesh testing

PURPOSE

This study uses free-floating contractile fibroblast-populated collagen matrices (FPCMs) to test the shrinkage of different hernia mesh products. We hope to present this model as a proof of concept for the development of in vitro hernia mesh testing-a novel technology with interesting potential.

METHODS

FPCMs were formed by seeding Human Dermal Fibroblasts into collagen gels. FPCMs were seeded with three different cell densities and cast at a volume of 500 μl into 24-well plates. Five different mesh products were embedded within the collagen constructs. Gels were left to float freely within culture media and contract over 5 days. Photographs were taken daily and the area of the collagen gel and mesh were measured. Media samples were taken at days 2 and 4 for the purposes of measuring MMP-9 release. After 5 days, dehydrated FPCMs were also examined under light and fluorescence microscopy to assess cell morphology.

RESULTS

Two mesh products-the mosquito net and large pore lightweight mesh were found to shrink notably more than others. This pattern persisted across all three cell densities. There were no appreciable differences observed in MMP-9 release between products.

CONCLUSIONS

This study has successfully demonstrated that commercial mesh products can be successfully integrated into free-floating contractile FPCMs. Not only this, but FPCMs are capable of applying a contractile force upon those mesh products-eliciting different levels of contraction between mesh products. Such findings demonstrate this technique as a useful proof of concept for future development of in vitro hernia mesh testing.

Long Vax in the Eye: Long Post-COVID Vaccination Syndrome Presenting with Frosted Branch Angiitis

mRNA COVID-19 vaccines have been reported as protecting against COVID-19 and reducing its severity, and we have recognized post-vaccination symptoms recently. This research investigates the clinical trajectories of ocular disorders in a 51-year-old female who received a second dose of the BNT162b2 (Pfizer-BioNTech) mRNA COVID-19 vaccine. Exhibiting fever and blurred vision within 24 h post-vaccination, with progressive blurry vision over two months, she underwent in-depth ophthalmologic examinations, revealing intraocular cellular infiltration in anterior chamber, vitreous opacity, and frosted branch angiitis in both eyes. Comprehensive evaluations, including systemic workups as well as ocular and blood specimen analyses, excluded autoimmune and infectious etiologies, consolidating the diagnosis of vaccine-induced ocular inflammation. Despite adherence to prevailing therapeutic protocols, her condition showed no significant improvement over 18 months, pointing to a possible long post-COVID vaccination syndrome. Such persistent sequelae underscore the need for detailed studies to discern the interactions between vaccine-induced immune responses and the development of post-vaccination sequelae. Continual documentation of patients with long post-COVID vaccination syndrome is now essential to better understand the vaccine's immunological effects, aiding in improving global vaccination strategies.

Patterns and outcomes of late onset thyroid disturbances after COVID-19 vaccination: A report of 75 cases

Isolated cases of subacute thyroiditis exist in the early period of COVID-19 vaccination, largely after mRNA vaccines. Here we report late onset thyroid disturbances and persistent health issues in patients of thyroid disorders after COVID-19 vaccination. Seventy-five patients with post COVID-19 vaccination thyroid disturbances were identified. Among these, 41 had flare of underlying thyroid illness, majority occurring at a median time lag of 28.4 weeks since 2nd dose. Thirty-one cases of new onset hypothyroidism and three of new onset hyperthyroidism were reported, with a median time lag respectively of 17.2 and 22.6 weeks since 2nd dose. Most cases occurred after ChAdOx1-nCoV-19, which was the commonest vaccine employed in mass roll out in India. Significant improvement was observed in majority, after a median follow up of 22-26 weeks. New onset health issues persisting for ≥4 weeks were reported in 37.3% and were common in individuals with history of COVID-19 before vaccine. New onset metabolic, musculoskeletal, and reproductive disorders were the common health complaints. Active monitoring is warranted for late onset adverse events after COVID-19 vaccines of all types. Larger studies with involvement of unvaccinated individuals are required to understand the incidence and causality of late onset thyroid disturbances after COVID-19 vaccines.

Polyamine Dysregulation and Nucleolar Disruption in Alzheimer's Disease

A hypothesis of Alzheimer's disease etiology is proposed describing how cellular stress induces excessive polyamine synthesis and recycling which can disrupt nucleoli. Polyamines are essential in nucleolar functions, such as RNA folding and ribonucleoprotein assembly. Changes in the nucleolar pool of anionic RNA and cationic polyamines acting as counterions can cause significant nucleolar dynamics. Polyamine synthesis reduces S-adenosylmethionine which, at low levels, triggers tau phosphorylation. Also, polyamine recycling reduces acetyl-CoA needed for acetylcholine, which is low in Alzheimer's disease. Extraordinary nucleolar expansion and/or contraction can disrupt epigenetic control in peri-nucleolar chromatin, such as chromosome 14 with the presenilin-1 gene; chromosome 21 with the amyloid precursor protein gene; chromosome 17 with the tau gene; chromosome 19 with the APOE4 gene; and the inactive X chromosome (Xi; aka "nucleolar satellite") with normally silent spermine synthase (polyamine synthesis) and spermidine/spermine-N1-acetyltransferase (polyamine recycling) alleles. Chromosomes 17, 19 and the Xi have high concentrations of Alu elements which can be transcribed by RNA polymerase III if positioned nucleosomes are displaced from the Alu elements. A sudden flood of Alu RNA transcripts can competitively bind nucleolin which is usually bound to Alu sequences in structural RNAs that stabilize the nucleolar heterochromatic shell. This Alu competition leads to loss of nucleolar integrity with leaking of nucleolar polyamines that cause aggregation of phosphorylated tau. The hypothesis was developed with key word searches (e.g., PubMed) using relevant terms (e.g., Alzheimer's, lupus, nucleolin) based on a systems biology approach and exploring autoimmune disease tautology, gaining synergistic insights from other diseases.

Intraneural ganglion cyst of the peroneal nerve occurring after coronavirus disease-19 vaccination: A case report

Ganglion cysts are relatively common, but intraneural ganglion cysts (INGCs) within peripheral nerves are rare and poorly understood. We present the case of a 58-year-old woman who presented with acute right-foot drop. She experienced acute knee pain radiating from the lateral leg to the dorsal foot two days after the first coronavirus disease-19 (COVID-19) vaccination (BNT162b2, Pfizer-BioNTech). She had no history of trauma or medication use. Two weeks after the onset of symptoms, she developed a dorsiflexor weakness of the right foot (Medical Research Council grade, poor). The weakness worsened to a "trace" grade despite providing conservative management for one month. Ultrasonography revealed a fusiform echolucent structure within the course of the right common peroneal nerve around the fibular head. Magnetic resonance imaging revealed multiple intraneural cysts within the right common peroneal nerve. Nerve conduction and electromyographic studies revealed multiphasic motor unit action potentials accompanied by abnormal spontaneous activities in the innervated muscles, along with axonal degeneration of the deep peroneal nerves. Surgical removal of the cyst was performed, and the patient's symptoms gradually improved. Pathological examination revealed a cystic structure containing mucinous or gelatinous fluid and lined with flattened or cuboidal cells. The clinical course and sequential electromyographic findings relevant to this symptomatic cyst were temporally related to the vaccination date. The present case suggests that INGC-induced peroneal palsy is a possible complication after COVID-19 vaccination.

Ocular manifestations following COVID-19 vaccination

BACKGROUND

Immunologic and inflammatory adverse effects following vaccination against COVID-19 are being reported. While some reactions may develop denovo others concern its immunogenic effect in patients with pre-existing inflammatory conditions.

METHODS

Retrospective consecutive patients diagnosed with ocular inflammatory manifestations within 8 weeks of receiving COVID-19 vaccination who presented to a tertiary eye care centre in South India.

RESULTS

Ninety-eight eyes of 67 patients presenting with ocular inflammatory manifestations within 8 weeks following COVID-19 vaccination were studied. The mean age was 43 years (+/- 14.82; range 19-80 years). The most common presentations were anterior uveitis (n = 31, 31.7%), followed by panuveitis (n = 24, 24.5%). The mean time to onset of symptoms was 25 days (+/- 15.48; range 2-55 days) following a dose of vaccine. Among all patients, 39 (58.2%) had a previous history of ocular inflammation. Mean presenting visual acuity was 0.4 (0-4) logMAR units and mean final visual acuity was 0.2 (0-4) logMAR units. The causes for reduced vision included of cystoid macular edema (n=2, 2%), chorioretinal atrophy (n=2.2%), optic atrophy (n=1.1%), retinal vascular occlusion (n=1.1%) and acute retinal necrosis (n=1.1%).

CONCLUSION

Infective and immunogenic adverse events should be watched out for after COVID-19 vaccination. It is difficult to establish causality for such manifestations, nevertheless, most of them were mild and had good final visual outcomes.

Complications of Silicone Fillers in Gluteal Augmentation: An Unusual Case of Filler Migration and Granuloma Formation

Silicone liquid (polydimethylsiloxane) is an inert material commonly used for cosmetic purposes. A combination of both systematic and local devastating complications can cause end-organ toxicity and multi-organ dysfunction. In this article, we examine the literature and present a case of a patient who presented with lower extremity filler migration and granuloma formation 11 years post gluteal silicone injection. A 31-year-old woman who had received a gluteal silicone injection 11 years ago was experiencing painful erythema, progressive fibrosis, and swelling as the result of the injection. The patient was diagnosed with postfiller autoimmune syndrome. Multiple surgical interventions were conducted to remove the permanent filler from her left knee. As a result of multiple surgical sessions, the patient has been managed successfully with no relapses. This case demonstrated complications of an unusual silicone injection technique for gluteal augmentation. Despite silicone being considered inert, complications can arise years after injection, necessitating extensive medical intervention. This case also raises questions regarding the systemic effects of silicone fillers, warranting further research. Through this report, we aimed to enhance awareness and management of similar future cases.

Autoimmune/inflammatory syndrome induced by adjuvants (ASIA): past, present, and future implications

Adjuvants, as the name indicates, are adjoined material aimed to assist in functioning as when added to vaccines they are meant to boost the effect and strongly stimulate the immune system. The response of the immune system can be unpredictable, and the autoimmune/inflammatory syndrome induced by adjuvants (ASIA) was developed to address possible adverse reactions of an autoimmune and inflammatory type that may be caused by adjuvants. While ASIA, as a syndrome, was coined and defined in 2011; reports describing patients with vague and nonspecific clinical symptoms following vaccinations appeared much earlier. In other words, ASIA came to define, arrange, and unite the variety of symptoms, related to autoimmunity, caused not by the vaccine itself, rather by the adjuvant part of the vaccine such as aluminum, among others. Accordingly, the introduction of ASIA enabled better understanding, proper diagnosis, and early treatment of the disorder. Furthermore, ASIA was shown to be associated with almost all body systems and various rheumatic and autoimmune diseases such as systemic lupus erythematosus, antiphospholipid syndrome, and systemic sclerosis. In addition, the correlation between COVID-19 and ASIA was noticed during the pandemic. In this review, we summarized the reported effects of adjuvants and medical literature before and after ASIA was defined, the several ways ASIA can manifest and impact different systems of the body, and the incidences of ASIA during the COVID-19 pandemic. It is important to clarify, that vaccines are among, if not the, most effective means of fighting infectious diseases however, we believe that vaccines manufacturing is not above criticism, particularly when it comes to added substances possessing a risk of side effects.

Takayasu arteritis associated with autoimmune/inflammatory syndrome induced by adjuvants: a case-based review

Takayasu's arteritis (TA) is a chronic granulomatous vasculitis that predominantly affects the aorta and its major branches. Despite advancements in the understanding of the pathogenic pathways of vascular inflammation, the etiology and predisposing factors of TA remain to be fully understood. In susceptible individuals, exposure to adjuvants may trigger, unlock or unmask an autoimmune disorder, presenting as non-specific constitutional symptoms or a fully developed autoimmune syndrome such as vasculitis. Here, we hypothesize that TA could be triggered by siliconosis, a subtype of the autoimmune/inflammatory syndrome induced by adjuvants (ASIA). ASIA, also known as Shoenfeld syndrome, encompasses a wide range of autoimmune and immune-mediated diseases resulting from dysregulation of the immune response after exposure to agents with adjuvant activity. This case report describes the development of large artery vasculitis, TA, in an individual one year following the placement of silicone breast implants. The patient initially presented with non-specific symptoms, and multiple imaging methods were employed, including ultrasound diagnostics, CT angiography, and 18-fluorodeoxyglucose positron emission tomography/CT. These techniques revealed vasculitic alterations in the carotid arteries and thoracic aorta. Initial treatment with glucocorticosteroids proved ineffective, prompting the addition of steroid-sparing immunosuppressive agents. Due to the distinct clinical symptoms, disease progression, implant-associated fibrosis, and resistance to therapy, the potential involvement of implants in the development of large-vessel vasculitis was considered, and a potential association with ASIA was postulated. Although there is limited evidence to support a direct link between adjuvants and the pathogenesis of TA, similarities in cellular immunity between the two conditions exist. The diagnosis of this complex and potentially debilitating condition requires a comprehensive clinical examination, laboratory evaluation, and instrumental assessment. This will aid in identifying potential contributing factors and ensuring successful treatment.

The Areola study: design and rationale of a cohort study on long-term health outcomes in women with implant-based breast reconstructions

BACKGROUND

Implant-based breast reconstructions contribute considerably to the quality of life of breast cancer patients. A knowledge gap exists concerning the potential role of silicone breast implants in the development of so called 'breast implant illness' and autoimmune diseases in breast cancer survivors with implant-based reconstructions. Breast implant illness (BII) is a constellation of non-specific symptoms reported by a small group of women with silicone breast implants.

METHODS/DESIGN

The Areola study is a multi-centre retrospective cohort study with prospective follow-up aiming to assess the risk of BII and autoimmune diseases in female breast cancer survivors with and without silicone breast implants. In this report, we set out the rationale, study design and methodology of this cohort study. The cohort consists of breast cancer survivors who received surgical treatment with implant-based reconstruction in six major hospitals across the Netherlands in the period between 2000 and 2015. As comparison group, a frequency-matched sample of breast cancer survivors without breast implants will be selected. An additional group of women who received breast augmentation surgery in the same years will be selected to compare their characteristics and health outcomes with those of breast cancer patients with implants. All women still alive will be invited to complete a web-based questionnaire covering health-related topics. The entire cohort including deceased women will be linked to population-based databases of Statistics Netherlands. These include a registry of hospital diagnostic codes, a medicines prescription registry and a cause-of-death registry, through which diagnoses of autoimmune diseases will be identified. Outcomes of interest are the prevalence and incidence of BII and autoimmune diseases. In addition, risk factors for the development of BII and autoimmune disorders will be assessed among women with implants.

DISCUSSION

The Areola study will contribute to the availability of reliable information on the risks of BII and autoimmune diseases in Dutch breast cancer survivors with silicone breast implants. This will inform breast cancer survivors and aid future breast cancer patients and their treating physicians to make informed decisions about reconstructive strategies after mastectomy.

REGISTRATION

This study is registered at ClinicalTrials.gov on June 2^nd 2022 (NCT05400954).

Vaccines and Autoimmunity-From 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.

Development of ANCA-associated vasculitis followed by SARS-CoV-2 vaccination in a patient with HLA-DRB1*09: 01 allele

Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), presents with severe pneumonia and fatal systemic complications. Currently, SARS-CoV-2 vaccines are effective in reducing the risk of new onset and getting worse of the disease. However, autoimmune diseases such as antineutrophil cytoplasmic antibody (ANCA) associated vasculitis (AAV) have been reported to develop after COVID-19 vaccine administration. Case presentation: A 71-year-old woman presented with fever, malaise, urinary abnormalities and renal dysfunction after receiving the COVID-19 vaccine (Pfizer-BioNTech). We clinically diagnosed AAV with her manifestations and serological test (MPO-ANCA positive). Her clinical findings were improved after immunosuppressive therapy. We examined her genetic susceptibility to AAV and we found that her allele was HLA-DRB1*09:01, which is a risk allele of MPO-AAV. Mechanistically, SARS-CoV-2 vaccines would activate immunity, including neutrophils, and trigger AAV onset in this patient with a genetic risk to develop AAV. The pathophysiology of this case would share with that of autoimmune/inflammatory syndrome induced by adjuvants (ASIA) in the absence of external adjuvants.

The effect of explantation on systemic disease symptoms and quality of life in patients with breast implant illness: a prospective cohort study

Silicone breast implants (SBIs) have been subject to scientific scrutiny since the 1960's because of their potential link with systemic disease symptoms. Breast implant illness (BII) is a cluster of over 56 (systemic) symptoms attributed by patients to their SBIs. BII remains an unofficial medical diagnosis, although its symptoms include but are not limited to the clinical manifestations of autoimmune/inflammatory syndrome induced by adjuvants (ASIA). The aim of this study was to prospectively analyse the effect of explantation on clinical manifestations of ASIA/BII symptoms, as well as to compare (breast-surgery specific) QoL in patients pre- and postoperatively while recording relevant perioperative/patient data. A prospective cohort study was conducted on 140 patients consulting a single surgeon for explantation of SBIs at a single clinic from 2019 to 2021 via their general practitioner, a medical specialist or self-referral. Of all patients, medical (implant) history, lifestyle factors and biometric data were obtained. Patients filled out a novel ASIA/BII symptom-survey termed the ASIA-scale, three domains of the SF-36 and the augmentation module of the BREAST-Q before and four months after the operation. A total of 109 patients completed both the pre- and postoperative survey with a mean follow-up duration of 205 days. There was a significant decrease in all individual symptom scores as well as ASIA-scale summary scores after explantation (p < .001). All SF-36 subdomains showed significant improvement postoperatively (p < .001). The BREAST-Q subdomain 'satisfaction with breasts' improved significantly after explantation (p = .036). No statistically significant association was found between any clinical parameters (such as age, capsulectomy, rupture etc.) and the recovery of symptom scores. This is the largest prospective cohort study on SBI explantation to date showing significant improvement of the most common systemic complaints in SBI patients as well as improvement of satisfaction with breasts and overall quality of life.

Pilot Findings on SARS-CoV-2 Vaccine-Induced Pituitary Diseases: A Mini Review from Diagnosis to Pathophysiology

Since the emergence of the COVID-19 pandemic at the end of 2019, a massive vaccination campaign has been undertaken rapidly and worldwide. Like other vaccines, the COVID-19 vaccine is not devoid of side effects. Typically, the adverse side effects of vaccination include transient headache, fever, and myalgia. Endocrine organs are also affected by adverse effects. The major SARS-CoV-2 vaccine-associated endocrinopathies reported since the beginning of the vaccination campaign are thyroid and pancreas disorders. SARS-CoV-2 vaccine-induced pituitary diseases have become more frequently described in the literature. We searched PubMed/MEDLINE for commentaries, case reports, and case series articles reporting pituitary disorders following SARS-CoV-2 vaccination. The search was reiterated until September 2022, in which eight case reports were found. In all the cases, there were no personal or familial history of pituitary disease described. All the patients described had no previous SARS-CoV-2 infection prior to the vaccination episode. Regarding the type of vaccines administered, 50% of the patients received (BNT162b2; Pfizer-BioNTech) and 50% received (ChAdOx1 nCov-19; AstraZeneca). In five cases, the pituitary disorder developed after the first dose of the corresponding vaccine. Regarding the types of pituitary disorder, five were hypophysitis (variable clinical aspects ranging from pituitary lesion to pituitary stalk thickness) and three were pituitary apoplexy. The time period between vaccination and pituitary disorder ranged from one to seven days. Depending on each case's follow-up time, a complete remission was obtained in all the apoplexy cases but in only three patients with hypophysitis (persistence of the central diabetes insipidus). Both quantity and quality of the published data about pituitary inconveniences after COVID-19 vaccination are limited. Pituitary disorders, unlike thyroid disorders, occur very quickly after COVID-19 vaccination (less than seven days for pituitary disorders versus two months for thyroid disease). This is partially explained by the ease of reaching the pituitary, which is a small gland. Therefore, this gland is rapidly overspread, which explains the speed of onset of pituitary symptoms (especially ADH deficiency which is a rapid onset deficit with evocative symptoms). Accordingly, these pilot findings offer clinicians a future direction to be vigilant for possible pituitary adverse effects of vaccination. This will allow them to accurately orient patients for medical assistance when they present with remarkable symptoms, such as asthenia, polyuro-polydipsia, or severe headache, following a COVID-19 vaccination.

Two Cases of Autoimmune Syndrome Induced by Adjuvants (ASIA): A Multifaceted Condition Calling for a Multidisciplinary Approach

Silicone implants have been used for cosmetic enhancement and reconstructive purposes for over 60 years. Despite assiduous efforts to ensure safety, there is continuous evidence that they are not as biologically inert as previously postulated. We present two cases of autoimmune syndrome induced by adjuvants (ASIA) in Hispanic women. The first patient developed biopsy-proven immune-mediated necrotizing myopathy that was successfully treated with the combination of silicone explantation along with immunosuppressive therapy. Findings after implant removal demonstrated rupture and leakage of silicone from gluteal implants. The second patient developed autoimmune hemolytic anemia in the setting of a ruptured silicone breast implant. Similarly, the patient was treated with corticosteroids followed by breast implant removal with complete resolution of symptoms. The successful treatment of these patients was achieved by collaboration between rheumatology and plastic surgery, which emphasizes the need for a multidisciplinary approach in the diagnosis and management of patients with ASIA.

ASIA syndrome with severe lupus - A case report

The autoimmune/inflammatory syndrome induced by adjuvants (ASIA), also known as Shoenfeld's syndrome, encompasses several autoimmune conditions/phenomena that are triggered following the exposure to materials with an adjuvant activity known to augment an antigen-driven immune response. In some inherently vulnerable patients, they act as second hits to trigger or unmask an autoimmune disorder which ranges from generalized non-specific constitutional symptoms, and autoantibody production, to a new onset, of a fully-fledged autoimmune syndrome. In this manuscript, we present a case of a 37-year-old lady who developed systemic lupus erythematosus characterized by mucocutaneous, musculoskeletal, hematological neurological, and renal involvement a few years after silicone breast implants.

A Case Series on the COVID-19 Vaccines and Possible Immune-Related Adverse Events: A New Challenge for the Rheumatologists

The COVID-19 pandemic has been a prime health issue since December 2019. Consequently, there has been an urgent need to prevent severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) infection and its associated morbidity and mortality. The currently available vaccines are designed to prevent infection. Their efficacy and safety have been demonstrated in clinical trials. Yet, given the short duration of the trials and the urgency to start vaccination, adverse events have been reported worldwide in real-life data format. Immune-mediated disease flares or new-onset inflammatory diseases following vaccine administration have recently been reported worldwide. Here, we present three cases of inflammatory arthritis (IA) caused by the BNT162b2 COVID vaccination, including two new-onset cases and one case of a flare of existing disease. The first case is new-onset IA, the second case is new-onset rheumatoid arthritis, and the third case is a flare of existing rheumatoid arthritis. Given the timeline of when our patients developed either a flare of their existing rheumatoid arthritis or new-onset IA or polymyalgia rheumatica (PMR) (a few days after receiving the COVID-19 vaccine), in addition to the currently available evidence of documented similar cases post administration of mRNA vaccines, as well as the link between their mechanism of action and the pathogenesis of those diseases, we can speculate a causal relationship between the vaccine and the triggering of these disease entities. In the future, it is important to consider that autoimmune diseases might be triggered or flared by the administration of vaccines, which appears to be associated with the COVID vaccine as well. Further evaluation of its incidence will provide additional clarity, though the rarity of this occurrence in the setting of more than half of the US population becoming vaccinated indicates that the benefit of the vaccine in terms of protection from COVID morbidity and mortality far outweighs this risk.

A Systematic Review of Reported Cases of Immune Thrombocytopenia after COVID-19 Vaccination

With the recent outbreak of the COVID-19 pandemic and emergency use authorization of anti-SARS-CoV-2 vaccines, reports of post-vaccine immune thrombocytopenia (ITP) have gained attention. With this systematic review, we aim to analyze the clinical characteristics, therapeutic strategies, and outcomes of patients presenting with ITP after receiving COVID-19 vaccination. Medline, Embase, and Ebsco databases were systematically explored from inception until 1 June 2022. Case reports and case series investigating the association between the anti-SARS-CoV-2 vaccine and ITP were included. We found a total of 66 patients. The mean age of presentation was 63 years with a female preponderance (60.6%). Sixteen patients had pre-existing ITP. The mean time from vaccine administration to symptom onset was 8.4 days. More ITP events were triggered by mRNA vaccines (BNT162b2 (n = 29) > mRNA-1273 (n = 13)) than with adenoviral vaccines (ChAdOx1-S AstraZeneca (n = 15) > Ad26.COV2-S (n = 9)). Most of the patients were treated with steroids or IVIG, or both. The overall outcome was promising, with no reported deaths. Our review attempts to increase awareness among physicians while evaluating patients presenting with thrombocytopenia after receiving the vaccine. In our solicited opinion, the rarity of these events and excellent outcomes for patients should not change views regarding the benefits provided by immunization.

SARS-CoV-2 vaccination and uveitis: Are they linked?

In 2019, the discovery of a new strain of Coronavirus, later referred to as SARS-CoV2 took the world by storm, leading to a pandemic and shutting down all global activities. Several measures were taken adequately to combat the viral havoc, including developing numerous vaccines. All the vaccines currently available for the general population went through rigorous screenings and trials to ensure maximum safety and were only approved after that. However, once they were rolled out in the markets and administered to the population, some adverse reactions were reported, one of which included uveitis. It is an ocular inflammatory condition of the uveal tract, choroid, or iris. If untreated, it can lead to severe consequences, including blindness. It is further divided into four categories based on its anatomical location. Despite the rare incidence of uveitis following COVID-19 vaccination, it may contribute to vaccine hesitancy; hence addressing and digging into the pathophysiological cause is crucial. This study evaluates all the pathophysiological and demographical links between COVID-19 vaccination and uveitis, suggesting appropriate management plans.

Recurrent, non-traumatic, non-exertional rhabdomyolysis after immunologic stimuli in a healthy adolescent female: a case report

Background

Dysferlinopathy refers to a heterogenous group of autosomal recessive disorders that affect a skeletal muscle protein called dysferlin. These mutations are associated with limb-girdle muscular dystrophy type 2B, Miyoshi myopathy, asymptomatic hyperCKemia, and distal myopathy with anterior tibial onset.

Case presentation

A 16 year old female presented with myalgia, weakness and dark urine one week after her second BNT162b2 mRNA (Pfizer) vaccine. Initial serum creatine kinase (CK) was measured at 153,000 IU/L, eventually up-trending to over 200,000 IU/L. However, stable renal function precluded hemodialysis allowing discharge after 10 days of intravenous (IV) hydration and alkaline diuresis.

Just two years prior to the current presentation, the patient was hospitalized following Group A Streptococcal pharyngitis infection complicated by rhabdomyolysis. She presented with fatigue, lower extremity weakness, and dark oliguria with CK measuring 984,800 IU/L. IV hydration was attempted however hemodialysis was ultimately required throughout her 24-day hospital stay. Her episode was presumed to be idiopathic and no further work-up was performed at that time.

During the patient’s current hospitalization, she reported similar symptomology (myalgias and weakness) following her first quadrivalent Gardasil vaccine at age 11. No hospitalization was required at that time. A comprehensive workup was now initiated while the patient was being treated for her suspected second or third non-exertional, non-traumatic rhabdomyolysis. Rheumatologic, metabolic, infectious, and endocrinologic workup were all unremarkable. Patient eventually had whole exome sequencing performed which revealed a heterozygous pathogenic variant in the DYSF gene (DYSF c.2643 + 1G > A) encoding dysferlin. No clinically significant sequelae occurred thus far.

Conclusions

While there have been reports of symptomatic heterozygote carriers of dysferlinopathies, to our knowledge none have been associated with recurrent rhabdomyolysis after immunogenic stimuli. This unique case presentation highlights the importance of a multi-disciplinary care team, the utility of modern whole-exome gene sequencing, and the future challenges of balancing vaccine risk vs benefit.

Three's Company: Coexistence of Silicosis, Scleroderma, and Sjogren Syndrome in a Single Patient

We describe a patient who presented with silicosis, scleroderma, and Sjogren syndrome all at the same time. The diagnoses in this case are all associated with continuous exposure to crystalline silica at the patient's workplace. The following report discusses this unique presentation.

An Overview of Vaccine Adjuvants: Current Evidence and Future Perspectives

Vaccinations are one of the most important preventive tools against infectious diseases. Over time, many different types of vaccines have been developed concerning the antigen component. Adjuvants are essential elements that increase the efficacy of vaccination practises through many different actions, especially acting as carriers, depots, and stimulators of immune responses. For many years, few adjuvants have been included in vaccines, with aluminium salts being the most commonly used adjuvant. However, recent research has focused its attention on many different new compounds with effective adjuvant properties and improved safety. Modern technologies such as nanotechnologies and molecular biology have forcefully entered the production processes of both antigen and adjuvant components, thereby improving vaccine efficacy. Microparticles, emulsions, and immune stimulators are currently in the spotlight for their huge potential in vaccine production. Although studies have reported some potential side effects of vaccine adjuvants such as the recently recognised ASIA syndrome, the huge worth of vaccines remains unquestionable. Indeed, the recent COVID-19 pandemic has highlighted the importance of vaccines, especially in regard to managing future potential pandemics. In this field, research into adjuvants could play a leading role in the production of increasingly effective vaccines.

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.

Thyroid as a target of adjuvant autoimmunity/inflammatory syndrome due to mRNA-based SARS-CoV2 vaccination: from Graves' disease to silent thyroiditis

BACKGROUND

As COVID-19 became a pandemic, the urgent need to find an effective treatment vaccine has been a major objective. Vaccines contain adjuvants which are not exempt from adverse effects and can trigger the autoimmune/inflammatory syndrome induced by adjuvants (ASIA). There is very little information about autoimmune endocrine disease and the ASIA after the use of mRNA-based SARS-CoV2 vaccination.

CASE SERIES

We report three cases and also review the literature showing that the thyroid gland can be involved in the ASIA induced by the mRNA-based SARS-CoV2 vaccination. We present the first case to date of silent thyroiditis described in the context of SARS-CoV2 vaccination with Pfizer/BioNTech. Also, we discuss the first subacute thyroiditis in the context of SARS-CoV2 vaccination with the Moderna's vaccine. Finally, we provide another case to be added to existing evidence on Graves' disease occurring post-vaccination with the Pfizer/BioNTech vaccine.

DISCUSSION

Adjuvants play an important role in vaccines. Their ability to increase the immunogenicity of the active ingredient is necessary to achieve the desired immune response. Both the Moderna and the Pfizer/BioNTech vaccines use mRNA coding for the SARS-CoV2 S protein enhanced by adjuvants. In addition, the cross-reactivity between SARS-CoV2 and thyroid antigens has been reported. This would explain, at least, some of the autoimmune/inflammatory reactions produced during and after SARS-CoV2 infection and vaccination.

CONCLUSION

The autoimmune/inflammatory syndrome induced by adjuvants involving the thyroid could be an adverse effect of SARS-CoV2 vaccination and could be underdiagnosed.

Graves' Disease Following COVID-19 Vaccination

Autoimmune endocrine diseases have been reported after influenza and the human papillomavirus vaccine, but there is limited data on autoimmune diseases after coronavirus disease 2019 (COVID-19) vaccination. Our report is about a 42-year-old Caucasian male and a 68-year-old Caucasian female who developed Graves' disease after receiving Moderna (Moderna, Inc., Cambridge, Massachusetts, United States) and Johnson & Johnson (Johnson & Johnson, New Brunswick, New Jersey, United States) vaccines, respectively. Both patients had no previous autoimmune thyroiditis and had normal thyroid function but developed hyperthyroidism characterized by suppressed thyroid-stimulating hormone (TSH), elevated free T4 level, and TSH receptor antibodies after vaccination. COVID-19 vaccines, either mRNA-based (Moderna) or non-mRNA-based (Johnson & Johnson), can cause Graves' disease. The clinical manifestations are similar to Graves' disease but without ocular manifestations.

ASIA syndrome: Adverse reaction or autoimmunity?

Introduction

Adjuvant-Induced Autoimmune / Auto-inflammatory Syndrome (ASIA) is an immune-mediated condition by the exposure of material previously considered inert, such as silicone, aluminum salts, mineral oils, hyaluronic acid and metallic implants. In addition to a genetic component, there is a risk of development of an undifferentiated connective tissue disease, which varies clinically and laboratorially depending on the adjuvant material used.

Patients and methods

This paper addresses two cases reported, in caucasian subjects, born and residents in Madeira Island, Portugal. In this article are described two different histological patterns occurring in ASIA patients, due to mammoplasty with silicone.

Conclusion

Although ASIA does not meet the diagnostic requirements for connective tissue disease, there is a close relationship with the development of autoimmune conditions. These cases aim to alert the medical community to the existence of this entity, encourage the notification of situations arising from exposure to adjuvants and investigate the presence of a genetic predisposition and a suggestive histological pattern in excisional biopsies of satellite adenomegalies.

COVID-19 and the Endocrine System: A Review of the Current Information and Misinformation

Coronavirus disease 2019 (COVID-19) infection primarily involves the respiratory system but has many noteworthy extra pulmonary manifestations as well. We write this review to highlight the basis of some pathophysiological mechanisms of COVID-19 infection-induced endocrine dysfunction. Different scientific databases and institutional websites were searched to collect and consolidate the most up-to-date data relating to COVID-19 infection and endocrine systems. Hypopituitarism, central diabetes insipidus, SIADH, thyroid abnormalities, hyperglycemia, adrenal insufficiency, orchitis and alteration in sperm morphology have been reported in case reports of patients with COVID-19 infection. Data focusing on COVID-19 vaccination was also searched to summarize the effect, if any, on the endocrine system. Endocrinopathies noted post COVID-19 vaccination, including cases of adrenal hemorrhage, new onset Type II Diabetes Mellitus and subacute thyroiditis, are also discussed in this review. This review calls attention to the misinformation relating to COVID-19 vaccination with supposed endocrine effects such as infertility and problems with pregnancy. Rebutting these misconceptions can help increase compliance and maximize COVID-19 vaccination to the public.

Case Report: Associated Ocular Adverse Reactions With Inactivated COVID-19 Vaccine in China

The vaccine is still the best clinical measure for effective prevention and control of coronavirus disease 2019 (COVID-19). The vaccine-associated ocular adverse reactions should be noted in detail among the medical community. We reported twelve eyes of 9 patients presented at the Department of Ophthalmology, Qilu Hospital of Shandong University from March to August 2021 with ocular complaints following COVID-19 vaccination. The main inclusion criterion was the development of ocular symptoms within 14 days after receiving a dose of an inactivated COVID-19 vaccine. The mean (SD) age was 44.7 ± 16.5 years (range, 19–78 years), among which seven (77.8%) cases were women. The mean time of ocular adverse events was 7.1 days (range, 1–14 days) after receiving the inactivated COVID-19 vaccine. One patient was diagnosed with choroiditis, 1 with uveitis, 4 with keratitis, 1 with scleritis, 1 with acute retinal necrosis, and 1 with iridocyclitis. Although the causal relationship between vaccines and ocular adverse events cannot be established from this case series report, physicians should pay attention to the ocular adverse reactions following the COVID-19 vaccine administration.
