Silicone implant incompatibility syndrome (SIIS): A frequent cause of ASIA (Shoenfeld’s syndrome)

The Spectrum of Non-neoplastic Changes Associated With Breast Implants: Histopathology, Imaging, and Clinical Significance

Breast implant-associated anaplastic large cell lymphoma has been recognized as a distinct entity in the World Health Organization classification of hematolymphoid neoplasms. These neoplasms are causally related to textured implants that were used worldwide until recently. Consequently, there is an increased demand for processing periprosthetic capsules, adding new challenges for surgeons, clinicians, and pathologists. In the literature, the focus has been on breast implant-associated anaplastic large cell lymphoma; however, benign complications related to the placement of breast implants occur in up to 20% to 30% of patients. Imaging studies are helpful in assessing patients with breast implants for evidence of implant rupture, changes in tissues surrounding the implants, or regional lymphadenopathy related to breast implants, but pathologic examination is often required. In this review, we couple our experience with a review of the literature to describe a range of benign lesions associated with breast implants that can be associated with different clinical presentations or pathogenesis and that may require different diagnostic approaches. We illustrate the spectrum of the most common of these benign disorders, highlighting their clinical, imaging, gross, and microscopic features. Finally, we propose a systematic approach for the diagnosis and handling of breast implant specimens in general.

Morphea-like discoid lupus erythematosus in a patient with a history of polyacrylamide gel injection: A case report

BACKGROUND

Discoid lupus erythematosus (DLE) is an autoimmune disease with multifactor etiology which develops in genetically susceptible patients. Rarely, DLE lesions can mimic other connective tissue disorders such as morphea. The growing application of soft tissue fillers is associated with increasing complications. Some substances used for soft tissue augmentation such as silicon implants may trigger lupus erythematosus diseases.

CASE REPORT

Here we report a case of morphea-like discoid lupus erythematosus developed several years after polyacrylamide dermal filler (PAAG) injection for facial rejuvenation.

CONCLUSION

As noninvasive procedures like dermal filler injections are increasing worldwide, physicians may consider the long-term probable side effects of these compounds.

Breast implant illness: Is it causally related to breast implants?

Once believed to be completely inert implants, Silicon Breast Implants (SBIs) have been shown to be able to induce a chronic inflammatory response in the body which can lead to a variety of possible manifestations ranging from the most common capsular contraction to rarer conditions such as malignancies and autoimmune diseases. Among the latter, new syndromes have been consistently recognized: Breast Implant Illness (BII) and autoimmunity/autoinflammatory syndrome induced by adjuvants (ASIA syndrome/Shoenfeld's Syndrome). The pathophysiological mechanisms underlying such syndromes are not yet clear and the overlap they show with other common conditions have sparked an important debate in the scientific community regarding their existence and their cause-effect relationship with SBIs. In this article Professor Cohen Tervaert and Professor Bassetto, leading experts in the field, are going to present arguments in favor and against such causal relationship according to the latest scientific evidence. Professor Cohen Tervaert is going to demonstrate how the evidence available is enough to prove a causal relationship as defined by the Bradford Hill's criteria. Professor Bassetto is going to highlight how the many biases that afflict the available evidence prevent us from drawing such conclusions. Professor Shoenfeld is going to moderate the discussion with its insightful conclusions.

Allergic manifestations in women with silicone breast implants

INTRODUCTION

Silicone breast implants (SBI) result in immune dysregulation and are associated with autoimmune diseases. Recently, we reported dysregulated levels of IgG autoantibodies directed against G protein-coupled receptors (GPCRs) of the autonomic nervous system which were linked to the autoimmune dysautonomia in silicone breast implant illness (SBII).

AIMS

We aimed to explore the possible association between allergy with dysregulated IgE autoantibodies directed against GPCRs of the autonomic nervous system in women with SBI.

METHODS

Circulating levels of IgE autoantibodies against GPCRs of the autonomic nervous system (adrenergic, muscarinic, endothelin and angiotensin receptors) have been evaluated in women with SBIs who complained of allergic symptoms, and compared to subjects with SBI without allergic manifestations and to age-matched healthy women without SBI.

RESULTS

We report a significant dysregulation in three circulating autoantibodies: IgE-beta1 adrenergic receptor (B1AR), IgE-alpha 1 adrenergic receptor (A1AR) and IgE-muscarinic acetylcholine receptor type 1 (M1R) autoantibodies in women with SBI who complained of allergic symptoms.

CONCLUSIONS

Allergic reactions associated with SBI are not uncommon. Imbalance of circulating levels of IgE autoantibodies against GPCRs of the autonomic nervous system might play a role not only in allergic reactions, but also in other enigmatic aspects of SBII such as autoimmune dysautonomia.

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.

One-step Glandular Reconstruction after Breast Implant Removal: Technical Refinements and Grafting of the Inferior Dermoglandular Flap

The number of breast implant removal procedures are rising. Among the reasons why patients seek breast implant removal, the autoimmune/inflammatory syndrome induced by adjuvants (ASIA), also named breast implant illness, is increasingly common. ASIA is an entity that incorporates diverse autoimmune conditions induced by the exposure to various adjuvants, including silicone, and it is characterized by systemic symptoms reminiscent of autoimmune disorders. Implant removal has the most effective treatment for ASIA. We describe a technique for glandular cone reconstruction after complete capsulectomy and implant removal. It combines an inverted-T superomedial pedicled mastopexy with fat grafting of the breast quadrants and of the inferior dermoglandular flap in two patients affected by ASIA. Implant removal allowed symptom resolution in both patients at 10 and 12 months follow-up. Both patients were satisfied with the aesthetic outcome after implant removal in terms of breast softness, projection, and volume. Our technique is easy, reproducible, and allowed for restoration of breast contour, volume, and shape after implant removal. Although initially conceived in patients with ASIA, this technique can be used for patients seeking implant removal for any indication.

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.

Autoimmune/inflammatory syndrome induced by adjuvants in a woman with Hashimoto thyroiditis and familial autoimmunity-a case report and literature review

Introduction

Autoimmune/inflammatory syndrome induced by adjuvants (ASIA) consists of a wide spectrum of symptoms and immunological features that are believed to develop in predisposed individuals after exposure to an adjuvant, including a silicone breast implant (SBI). Different autoimmune diseases (AIDs) have been associated with ASIA, but ASIA development after SBI in women with Hashimoto thyroiditis (HT) and familial autoimmunity has rarely been described.

Case report

A 37-year-old woman presented in 2019 with arthralgia, sicca symptoms, fatigue, + antinuclear antibody (ANA), + anti SSA, and + anticardiolipin Immunoglobulin G (IgG) antibodies. She was diagnosed with HT and vitamin D deficiency in 2012. The familial autoimmunity was present: the patient's mother had been diagnosed with systemic lupus erythematosus and secondary Sjogren's syndrome and her grandmother with cutaneous lupus and pernicious anemia. In 2017, the patient had a cosmetic SBI procedure that was complicated by repeated right breast capsulitis. After 2 years of irregular visits due to COVID-19, she presented with + ANA, + anticentromere antibodies both in sera and seroma, sicca syndrome, arthralgias, twinkling in extremities, abnormal capillaroscopic findings, and reduced diffusing capacity of the lungs for carbon monoxide. She was diagnosed with ASIA, and antimalarial and corticosteroid therapy were introduced.

Conclusion

In patients with HT and familial autoimmunity, SBI should be carefully considered due to the possibility of ASIA development. Hashimoto thyroiditis, familial autoimmunity, and ASIA seem to be interconnected in the complex mosaic of autoimmunity in predisposed individuals.

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).

The Prevalence of Hearing Impairments in Women with Silicone Breast Implants

Many women with silicone breast implants (SBIs) report non-specific complaints, including hearing impairments. Hearing impairment appears to be associated with a number of autoimmune conditions. The current study aimed to evaluate the prevalence and severity of hearing impairments among women with SBIs and to explore potential improvements in their hearing capability following implant removal. Symptomatic women with SBIs (n = 160) underwent an initial anamnestic interview, and women who reported hearing impairments were selected for the study. These women completed self-report telephone questionnaires regarding their hearing difficulties. Some of these women underwent subjective and objective hearing tests. Out of 159 (50.3%) symptomatic women with SBIs, 80 reported hearing impairments, including hearing loss (44/80; 55%) and tinnitus (45/80; 56.2%). Five out of seven (71.4%) women who underwent an audiologic evaluation exhibited hearing loss. Of women who underwent silicone implant removal, 27 out of 47 (57.4%) reported the improvement or resolution of their hearing complaints. In conclusion, hearing impairment is a frequent complaint among symptomatic women with SBIs, and tinnitus was found to be the most common complaint. A significant reduction in hearing difficulties was observed following silicone implant removal. Further studies using larger populations are needed to verify the occurrence of hearing impairments in these women.

Autoimmune/inflammatory syndrome induced by adjuvants (ASIA) in 2023

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.

Patients With Systemic Reaction to Their Hernia Mesh: An Introduction to Mesh Implant Illness

In our practice, we have noticed an increased number of patients requiring mesh removal due to a systemic reaction to their implant. We present our experience in diagnosing and treating a subpopulation of patients who require mesh removal due to a possible mesh implant illness (MII). All patients who underwent mesh removal for indication of mesh reaction were captured from a hernia database. Data extraction focused on the patients' predisposing medical conditions, presenting symptoms suggestive of mesh implant illness, types of implants to which reaction occurred, and postoperative outcome after mesh removal. Over almost 7 years, 165 patients had mesh removed. Indication for mesh removal was probable MII in 28 (17%). Most were in females (60%), average age was 46 years, with average pre-operative pain score 5.4/10. All patients underwent complete mesh removal. Sixteen (57%) required tissue repair of their hernia; 4 (14%) had hybrid mesh implanted. Nineteen (68%) had improvement and/or resolution of their MII symptoms within the first month after removal. We present insight into a unique but rising incidence of patients who suffer from systemic reaction following mesh implantation. Predisposing factors include female sex, history of autoimmune disorder, and multiple medical and environmental allergies and sensitivities. Presenting symptoms included spontaneous rashes, erythema and edema over the area of implant, arthralgia, headaches, and chronic fatigue. Long-term follow up after mesh removal confirmed resolution of symptoms after mesh removal. We hope this provides greater attention to patients who present with vague, non-specific but debilitating symptoms after mesh implantation.

Silicone particles in capsules around breast implants: Establishment of a new pathological methodology to assess the number of particles around breast implants

INTRODUCTION

The presence of silicone particles in breast implant capsules has been observed since the 1970s. Since then, little data has been published regarding the amount of silicone that is susceptible to migrate into the capsule. Quantifying the amount of silicone migration from the implant to the capsule could inform on the level of silicone exposure a patient with breast implants may experience in the short- or long-term. The objective of this study is to present a histological quantification methodology of the number of silicone particles present in breast implant capsules.

MATERIALS AND METHODS

A prospective study was performed on capsule samples from patients requiring revision surgery. The slides were digitalized and analyzed with a viewer software. For each sample, we (1) manually counted each silicone particle, (2) measured the average particle size, (3) measured the capsule surface area, and (4) calculated the particle number density in each capsule sample. The average of all capsule samples' particle number densities was then compared to the total volume of the capsule to estimate the total number of silicone particles found within the capsule of each breast implant.

RESULTS

Six capsules from six different patients were analyzed. Two capsules were from saline implants while four capsules were from silicone implants. All four silicone implant capsules contained between 352,928 and 9,002,235 silicone particles. The particle number density ranged from 20.5 to 683.5 particles per mm³ of capsule. The two saline-filled implant capsules were free of silicone particles. The average of all capsule samples' particle number densities was then compared to the total volume of the capsule to estimate the total number of silicone particles found within the capsule of each breast implant.

CONCLUSIONS

We describe a new and reproducible methodology to quantify realistically the silicone particles in the periprosthetic capsule of breast implants.

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.

[The Emerging Interest in Breast Implant Illness and its impact on Patient Behavior]

Breast implant illness (BII) is a loosely defined term for a collection of non-specific systemic symptoms that are hypothesised to be associated with breast implants. BII symptoms include fatigue, hair loss, rashes, chronic pain, and others. However, conclusive evidence for a causal relationship between silicone implants and BII remains lacking. In the light of recent findings that textured implants can, in rare cases, lead to breast implant-associated anaplastic large cell lymphoma (BIA-ALCL), a potential link between breast implants and BII is conceivable and justifies further investigation. We observe a growing number of patients seeking consultation and treatment for systemic symptoms related to breast implants, which is reflected in increasing interest in literature and social media. The aim of this work was to investigate the growing interest in BII. We now describe the clinical features of a patient who suffers from symptoms that are consistent with BII and contextualise clinical presentation in a review of literature and google trend analysis.

Progressive sensory ataxia and breast implant rupture, an uncommon presentation of a debated concept: a case report

Background

Autoimmune Syndrome Induced by Adjuvants (ASIA) is a concept introduced by Shoenfeld to group various disease entities believed to be triggered by an infection, silicone exposure or other external stimuli. A causal link between the use of silicone and the development of autoimmune diseases and lymphoma has been suggested in the past. Sjögren’s Syndrome (SS) is one of the autoimmune diseases that has been postulated as an example of ASIA syndrome. Although typically characterized by sicca, SS can manifest as a ganglionopathy as the primary presenting symptom. To our knowledge, this is the first case report in which a ganglionopathy unveiled an underlying SS in the context of a possible ASIA syndrome.

Case presentation

We describe a case of a 44-year-old woman who developed rapidly progressive sensory loss in the 4 limbs with a walking impairment due to the severe sensory ataxia. After extensive work-up, she was diagnosed with a ganglionopathy as the first symptom of SS, and the concurrent diagnosis of a bilateral breast implant leakage with severe inflammation due to silicone bleeding. After surgical removal of the prostheses and initiation of immunosuppressive therapy, stabilization of symptoms was achieved.

Conclusion

This case report brings to attention the possibility of a sensory ganglionopathy as first and isolated symptom of SS. The occurrence of SS in the setting of ASIA stir up the discussion about the safety of silicone breast implants.

Autoimmune/autoinflammatory syndrome induced by adjuvants: a focus on silicone

Autoimmune/autoinflammatory syndrome induced by adjuvants (ASIA) was first described in 2011 to cover disorders characterized by dysregulation of the immune system after exposure to an adjuvant. In the present review, the authors focus on silicone-induced ASIA. In the last two decades, there has been worldwide increase in the use of silicone breast implant (SBI) as an aesthetic procedure, raising concerns for possible effects on the immune system, especially in people who already have previous immune dysregulation. The authors did a critical review of the most important articles referring to silicone-induced ASIA, including most recent studies regarding physiopathologic mechanism. Despite large-scale epidemiological studies conducted to assess the association between SBI and autoimmune/rheumatic disorders, the results remain inconclusive, and the debate over the safety of SBIs remains heated. The explantation of silicone breast has been indicated for silicone-induced ASIA with improvement of unspecific symptoms in the majority of patients; however, the outcome seems different in patients with definitive autoimmune rheumatic disease (AIRD). There is no prospective study evaluating the risk of flares after SBI in patients who already have an AIRD. Therefore, based on the literature, we cannot contraindicate the procedure; however, we need to advertise about the risk of ASIA to the patients with AIRD. Long-term safety and implant-related outcomes should be discussed with these patients, considering each case individually, assessing genetic and environmental factors, and determining if the autoimmune disease is in remission or not, for shared decision among patient and the physician.

Patient-reported systemic symptoms in women with silicone breast implants: a descriptive cohort study

OBJECTIVE

An unknown portion of women with silicone breast implants (SBI) report development of systemic symptoms, recently named as 'breast implant illness (BII)'. We aim to describe the symptoms and characteristics of women with SBI reporting these systemic symptoms and compare the clinical course of women who chose to keep their implants, to women who had their implants removed.

DESIGN

Observational cohort study.

SETTING

Specialised BII out-patient clinic at Amsterdam UMC, the Netherlands, from 2011 to 2020.

PARTICIPANTS

All women presenting to the BII clinic with SBI and systemic symptoms.

RESULTS

467 women were included for baseline analyses and 398 women for follow-up. Most frequently reported systemic symptoms at baseline included fatigue (88%), arthralgia (71%), morning stiffness (59%), myalgia (48%), cognitive impairment (33%), peripheral neurological symptoms (30%) and lymphadenopathy (22%). Furthermore, 56% reported pre-existing allergies at baseline and positive antinuclear antibodies were observed in 23%. At follow-up with a median of 3.3 years (IQR 2-4), 152 women had their implants removed on clinical grounds. Symptoms improved significantly in 65 women (43%), improved moderately in 37 women (24%), did not change in 37 women (24%) and deteriorated in 13 women (9%). Women who underwent explantation showed more improvement of their systemic symptoms compared with women who did not (OR 2.9, 95% CI 1.3 to 6.2). Additionally, women who underwent explantation within 10 years after implantation improved significantly better than women who got the implants removed after 10 years (p=0.007). Lastly, local symptoms decreased from 75% to 34% after implant removal (p<0.0001).

CONCLUSION

Most women with SBI who developed systemic symptoms experienced improvement after explantation, especially when removed within 10 years after implantation. Early recognition of the pattern of systemic symptoms in women with SBI is important and implant removal should be considered.

Understanding Breast Implant-Associated Illness: A Delphi Survey Defining Most Frequently Associated Symptoms

BACKGROUND

Increased understanding of the constellation of symptoms referred to as breast implant illness is necessary to better address patient concerns, provide evidence-based care, and inform prospective patients about potential risks. The aim of this study was to reach consensus on the symptoms most frequently associated with breast implant illness, which will subsequently inform the development of a symptom severity scale.

METHODS

A literature search of peer-reviewed and gray literature was performed to identify a comprehensive list of symptoms associated with breast implant illness. This was followed by an online, three-round, modified Delphi survey where the list of symptoms was reviewed by an international panel to determine the top 20, 10, and five symptoms associated with breast implant illness. A virtual meeting of panelists was held to reach consensus on the symptoms to be included in a symptom severity scale.

RESULTS

A total of 44 symptoms were identified through the literature search. The modified Delphi survey panel consisted of patient research partners [n = 9 (34.6 percent)], plastic surgeons [n = 10 (38.5 percent)], researchers [n = 6 (23.1 percent)], and a member of the U.S. Food and Drug Administration [n = 1 (3.8 percent)]. The response rates of round 1, 2, and 3 were 85, 96, and 100 percent, respectively. Consensus was reached on the top 19 and top six symptoms to be included in long and short forms of a symptom severity scale.

CONCLUSIONS

There was a high level of agreement on the symptoms to be included in a symptom severity scale. The next steps include conducting in-depth qualitative interviews with women with these symptoms and breast implants to understand the experience and impact of these symptoms and develop the preliminary scale.

Breast Implant Illness: Surgical, Autoimmune, and Breast Reconstruction Associations

Breast implant illness refers to a combination of different symptoms related to breast implant surgery, including fatigue, brain fog, and arthralgias. This malaise occurs after cosmetic and reconstructive breast surgeries, although it has not been proven to be a disease. Even recent studies have reported concluding statements of the etiology, diagnosis, and treatment as unclear and widely unknown. Therefore, this review aimed to determine the associations between the manifestations of breast implant illness in surgery and breast reconstruction, as well as the autoimmune responses involved. Complications associated with breast implants include breast pain, capsular contracture, infections, as well as other manifestations specific to breast reconstruction. Moreover, patients with implants may present with new-onset systemic sclerosis, Sjögren’s syndrome, and connective tissue diseases. However, the incidence of capsular contracture has steadily decreased with each generation of implants, particularly since the development of textured implants, as well as with the use of antibiotics and antiseptic pocket irrigation. However, the incidence of anaplastic large cell lymphoma has increased with the use of textured implants. Remarkably, the autoimmune response to these implants remains unclear. Therefore, close follow-up, careful observation of any symptom presentation, and evidence-based treatment decisions are necessary for patients with breast implants.

Understanding Breast Implant Illness: Etiology is the Key

Because breast augmentation is one of the most popular cosmetic procedures, the issue of implant-related complications has been widely debated ever since the FDA approved the use of implants in 1962. Although decades have passed, breast implant illness (BII) still represents a poorly defined and controversial complication. With ongoing nonscientific discussion in the mainstream media and on social media, revealing the etiology of BII is urgent because knowledge of this subject ultimately influences patients' decisions. Little or no scientific research is currently available on BII and no final conclusions regarding its etiology, clinical manifestations, diagnostic criteria, or treatment have been made. This review aims to give an overview of the hypotheses on the etiology of BII and seeks inspiration to improve the conditions of BII patients.

A Practical Guide to Managing Patients With Systemic Symptoms and Breast Implants

Numerous studies have explored the possibility of an association between breast implants and systemic symptoms potentially linked to exposure to silicone. Some studies show no direct association whereas others provide insufficient scientific evidence to prove or disprove an association. Nonetheless, some patients with breast implants remain concerned about the possible role of their implants in systemic symptoms they may be experiencing. This paper provides a practical approach for plastic surgeons in managing patients with breast implants who present with systemic symptoms, including recommendations for patient counseling, clinical and laboratory assessment of symptoms, and/or referral. Integral components of patient counseling include listening attentively, providing unbiased information, and discussing the risks and benefits of options for evaluation and treatment. A thorough history and assessment of symptoms, including appropriate laboratory tests, may identify underlying conditions to expeditiously address patients’ health issues through a specialist referral. Diagnosing and treating disorders that are causing a patient’s symptoms, if unrelated to their implant, would avoid a potentially unnecessary surgery. Ultimately, better information is needed to reliably guide patients in an evidence-based fashion. Long-term follow-up of patients who are explanted to see what symptoms may or may not improve could be useful in educating patients. Control groups in studies prospectively following women with implants for development of systemic symptoms would also be useful because the symptoms reported are common in women without implants. Cases are presented to illustrate the recommendations for a practical approach toward management of women reporting systemic symptoms with breast implants.

Deciphering Key Foreign Body Reaction-Related Transcription Factors and Genes Through Transcriptome Analysis

Background: Silicone implants are widely used in the field of plastic surgery for wound repair and cosmetic augmentation. However, molecular mechanisms and signaling pathways underlying the foreign body reaction (FBR) of a host tissue to the silicone require further elucidation. The purpose of this study was to identify key FBR-related transcription factors (TFs) and genes through transcriptome analysis.

Methods: We used a rat model with a subcutaneous silicone implant in the scalp and performed high throughput sequencing to determine the transcriptional profiles involved in the FBR. The function was analyzed by Gene Ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway-enrichment analysis. A protein-protein interaction (PPI) network of differentially expressed mRNAs (DEmRNAs) was constructed to identify the hub genes and key modules and to determine the regulatory TF-mRNA relationships. In addition, the hub gene and transcript expression levels were determined by Quantitative Reverse Transcription polymerase Chain Reaction (qRT-PCR). Myofibroblasts differentiation and macrophage recruitment were identified by immunofluorescence. The protein expression of MMP9 was detected by immunohistochemistry and Western blot.

Results: We identified ten hub genes (Fos, Spp1, Fn1, Ctgf, Tlr2, Itgb2, Itgax, Ccl2, Mmp9, and Serpine1) and 3 TFs (FOS, IRF4, and SPI1) that may be crucial (particularly FOS) for the FBR. Furthermore, we identified multiple differentially expressed genes involved in several important biological processes, including leukocyte migration, cytokine‒ cytokine receptor interaction, phagocytosis, extracellular matrix (ECM) organization, and angiogenesis. We also identified potentially significant signaling pathways, including cytokine‒cytokine receptor interaction, phagosome, ECM‒receptor interaction, complement and coagulation cascades, the IL-17 signaling pathway, and the PI3K‒Akt signaling pathway. In addition, qRT-PCR confirmed the expression patterns of the TFs and hub genes, Western blot and immunohistochemistry validated the expression patterns of MMP9.

Conclusion: We generated a comprehensive overview of the gene networks underlying the FBR evoked by silicone implants. Moreover, we identified specific molecular and signaling pathways that may perform key functions in the silicone implant-induced FBR. Our results provide significant insights into the molecular mechanisms underlying silicone-induced FBR and determine novel therapeutic targets to reduce complications related to silicone implantation.

Breast Implant Illness and Cutibacterium acnes: A Case Report

Breast implant illness (BII) is a term to describe a wide range of nonspecific symptoms after breast implant placement. At present, no specific diagnostic criteria for BII exist, and there is limited solid understanding of what causes BII. There is some evidence that biofilm infections such as those caused by Cutibacterium acnes may play a role in the development of BII. We present a case of a 38-year-old White woman who developed BII symptoms (psychological and integumentary). After en bloc explantation, her tissue cultures resulted in C. acnes growth. Plastic surgeons should be aware of this potential complication and discuss it thoroughly with patients before breast implantation. Evidence suggests that biofilm infection with C. acnes may play a role in BII development. En bloc explantation is the typical treatment of choice. Plastic surgeons should be aware of C. acnes as a potential cause of BII and should counsel patients on the potential risks and remedies for BII.

Breast Implant Illness (BII): Real Syndrome or a Social Media Phenomenon? A Narrative Review of the Literature

Breast implant illness (BII) is a condition characterized by elusive diagnostic criteria and self-reported diverse disabling and distressing physical and psychological symptoms. With currently significant increase in public awareness, BII is perhaps becoming the most controversial subject in aesthetic and reconstructive breast surgery, generating heated debates between those who do not believe such a condition exists and those who demand its acceptance as a recognized diagnosis. Silicone incompatibility has been associated with "autoimmune/inflammatory syndrome induced by adjuvants" (ASIA syndrome) or Shoenfeld's syndrome. It is still unclear, however, whether BII symptoms would have occurred if no implants had been placed in the first place. The purpose of this literature review is to analyze critically the current state of scientific evidence related to this condition. Though the psychosomatic theory is most likely, the mechanism of BII symptoms is probably multifactorial. At present, BII being an underlying connective tissue disorder cannot be confirmed; moreover, whether improved aesthetic outcome and patient's overall satisfaction with the profile of their reconstructed or augmented breasts translate into decreased self-reported BII symptoms is still not well elucidated.

Silicone-induced granuloma of breast implant capsule mistaken for breast implant-associated anaplastic large cell lymphoma

For patients with breast implants who present with an isolated seroma, capsular contracture, or peri-implant mass, clinicians must rule out breast implant-associated anaplastic large cell lymphoma (BIA-ALCL). As non-malignant silicone-induced granuloma of breast implant capsule (SIGBIC) may mimic BIA-ALCL, particular care must be exercised to prevent misdiagnosis. In this report, we describe three cases of SIGBIC misdiagnosed as BIA-ALCL. In each of these cases, a preoperative evaluation including breast magnetic resonance imaging and physical examination, as well as the fact that a textured silicone implant was used in the patients, indicated a high probability of malignancy. In all three cases, however, an explorative operation and pathologic results revealed foreign body granulomas without malignant features. While it is critical that potential cases of BIA-ALCL be diagnosed and treated quickly, hasty judgments may lead to misdiagnosis and severe emotional distress in patients. Increased awareness of SIGBIC, specifically its mimicry of BIA-ALCL, may be helpful to avoid these outcomes.

Assessing Long-Term Outcomes in Breast Implant Illness: The Missing Link? A Systematic Review

SUMMARY

The purpose of this special topic article is to explore the current state of outcomes-based literature related to breast implant illness and summarize the key understandings that emerge from the summation of existing studies. While implanted silicone devices are some of the most ubiquitous products in modern medicine, the safety of silicone breast implants has long remained under scientific scrutiny. In the era of social media and with breast implants once again under public scrutiny with the recent connection of texture silicone implants to breast implant-associated anaplastic large-cell lymphoma, the borders between breast implant illness and other implant-related diseases are becoming clouded in the public eye. The surgical management options for breast implant illness range from simple implant explantation alone to complete en bloc capsulectomies, or even secondary exploratory operations for additional capsulectomy in persistently symptomatic patients. In this review of outcomes-based studies related to breast implant illness, the authors found that a subset of patients improves with surgical intervention but limited evidence to inform most current surgical management practices. Further, the nature of this illness renders it difficult to study. A carefully designed, large, prospective, outcomes-based study is still required if an evidence-based and sound treatment approach for this condition is to be established.

Effects of Silicone Breast Implants on Human Cell Types In Vitro: A Closer Look on Host and Implant

BACKGROUND

Silicone (gel) breast implants (SBI) are used world-wide for breast augmentation, and reconstruction or to correct breast deformities. They consist of two compounds: an elastomer silicone shell (envelope) and a silicone gel filler (core). Breast Implant Illness (BII) is a term used for women with SBI, who suffer from various of symptoms including myalgia, arthralgia, fatigue, fever, dry eyes and/or dry mouth (sicca), as well as cognitive disturbances, which are rated by these woman as response to SBI. The pathogenesis of these adverse effects as well as the histocompatibility and the SBI-cell interaction of silicone and its surrounding tissue (implant-host tissue interface) is a subject of current research. The main purpose of this review is to provide an overview of the current knowledge regarding the effects of silicone (gel and elastomer surfaces) of a SBI on different human cell types from experimental - in vitro - models.

METHODS

A comprehensive research was conducted by two independent reviewers in March and July of 2020 in the PubMed, MEDLINE, and Cochrane databases.

RESULTS

A number of 1328 articles on this topic were initially identified, of which 62 could be finally included an analysed in this review.

CONCLUSION

SBI may lead to a physiologic pro-inflammatory and foreign body host response with fibrous encapsulation accompanied by a disturbed Th17/Treg balance and IL-17 production. No causal relationship is known for systemic symptoms and/or autoimmune outcomes in the context of BII.

Self-Reported Health Complaints in Women Undergoing Explantation of Breast Implants

Background

Concerns about the safety of silicone breast implants (SBIs) have existed for years, but a causal relation between systemic complaints and SBIs has not been proven. Nevertheless, some women are worried and even request explantation.

Objectives

This study aimed to review the explantation procedures performed, focusing on patient-reported symptoms preoperatively, the effect of explantation, and the effect of breast reconstruction on these symptoms.

Methods

A retrospective chart review was performed for patients who had undergone explantation between 2010 and 2020 at Maastricht University Medical Center. Patients who had undergone tissue expander removal, tissue expander–implant exchange, or direct implant exchange were excluded.

Results

More than half of the patients undergoing explantation reported complaints, mostly pain. Some 15% reported systemic complaints they believed were implant related. Breast implant illness (BII) was found to be the fifth most common indication for explantation (11.2%). A history of either allergies or implant rupture resulted in higher odds ratios of having BII (odd ratios, 2.1 and 2.1, respectively). Subjective improvement of BII after explantation was reported by about 60% of patients.

Conclusions

A relatively low prevalence of suggested BII exists among women undergoing explantation; 1 in 9 procedures were performed for this reason. Allergy and implant rupture may increase the likelihood of having BII. About 60% of BII patients experienced an improvement in their complaints after implant removal. Autologous breast reconstruction appears a good alternative. Prospective studies into health complaints and quality of life should be performed to confirm the effectiveness of explantation as a therapy for BII.

Level of Evidence: 4

Breast implant illness: scientific evidence of its existence

INTRODUCTION

More than one million breast augmentation procedures using silicone breast implants (SBI) have been performed worldwide. Adverse events of SBI include local complications such as pain, swelling, redness, infections, capsular contracture, implant rupture and gel-bleed. Furthermore, patients experience systemic symptoms such as chronic fatigue, arthralgias, myalgias, pyrexia, sicca, and cognitive dysfunction. These symptoms received different names such as autoimmune/inflammatory syndrome induced by adjuvants (ASIA) due to silicone incompatibility syndrome and breast implant illness (BII). Because of chronic immune activation, BII/ASIA, allergies, autoimmune diseases, immune deficiencies and finally lymphomas may develop in SBI patients.

AREAS COVERED

Causality for SBI-related BII/ASIA is reviewed. To address the role of silicone implants in promoting causality, we utilized the Bradford-Hill criteria, with results highlighted in this article.

EXPERT OPINION

We conclude that there is a causal association between SBIs and BII/ASIA. Using data derived from patients with BII/ASIA and from other medically implanted devices, there appears to be clear pathogenic relationship between SBI and BII/ASIA. Breast implants cause characteristic systemic reactions in certain women, leading to symptoms of sufficient severity to warrant device removal. The morbidity suffered is variable. SBI removal resolves the symptoms in most women and removal is the most effective treatment.

ASIA (Shoenfeld's syndrome) due to hysteroscopic Essure sterilization

Essure (TM, Bayer; Leverkusen, Germany) may act as a potential cause of autoimmune/inflammatory syndrome by adjuvants (ASIA). Essure is a device hysteroscopically inserted into the fallopian tubes to elicit a local inflammatory response for permanent sterilization. Patients with ASIA present with a constellation of symptoms including fatigue, cognitive impairment, and arthralgias. It is well known that ASIA is triggered by implantation of foreign material such as breast implants and mesh for hernia repair. In the current study, we present a retrospective cohort of 33 patients electing to remove Essure due to pelvic pain and systemic symptoms consistent with an ASIA diagnosis, and detail a case report of an Essure patient. Furthermore, we reviewed the existing literature on adverse events associated with Essure and studies assessing outcomes following explantation. The concept that Essure may trigger ASIA is further supported by both in vivo and in vitro studies demonstrating immunostimulatory effects of the material components of the device. We conclude that the existing evidence is sufficient to recommend screening of Essure recipients for ASIA symptoms, and where indicated, discussion of the risks and potential benefits of surgical removal.

Aesthetic breast surgery: putting in context-a narrative review

Objective

This review article summarises the latest evidence for commonly undertaken procedures in aesthetic breast surgery with a focus on key principles of breast augmentation, reduction, and mastopexy. The paper also outlines various approaches and controversies as well as complications such as breast implant associated anaplastic large cell lymphoma (BIA-ALCL) and breast implant illness (BII) which are increasingly being recognised and becoming a challenge to manage.

Background

Changing trends of aesthetic breast surgery over the decades has warranted a continuous evolution of this field. The ability to deliver safe and appropriate care is dependent upon sound reconstructive principles and proper training. The lack of uniformity in either is a cause of concern. The impact of social media and changing perception of body image can also no longer be overlooked in the field of aesthetics and reconstruction.

Methods

Review of literature including recent journals, textbook chapters, online databases like PubMed, and current government and surgical society guidelines.

Conclusions

Breast reconstruction is based on sound surgical principles and it is imperative to follow these for the practice of this speciality. There are two important issues that revolve around this aspect of surgery. First relates to the urgent need to invest time and effort in improving regulations and outcomes in the cosmetic surgery industry. Second, it is crucial to promote and prioritize the development and training in this field as the principles of aesthetic breast surgery underpins oncoplastic breast surgery for management of cancer.

ALK-Negative Anaplastic Large Cell Lymphoma: Current Concepts and Molecular Pathogenesis of a Heterogeneous Group of Large T-Cell Lymphomas

Simple Summary

ALK- anaplastic large cell lymphoma (ALK- ALCL) is a rare subtype of CD30+ large T-cell lymphoma that typically affects older adults and has a poor prognosis. Recognition of its histopathologic spectrum, subtypes, and of other tumors that can resemble ALK- ALCL is crucial to avoid making a wrong diagnosis that could result in inappropriate treatment for a patient. In recent years, several important studies have identified recurrent molecular alterations that have shed light on the pathogenesis of this lymphoma. However, on the other hand, putting all this vast information together into a concise form has become challenging. In this review, we present not only a more detailed view of the histopathologic findings of ALK- ALCL but also, we attempt to provide a more simplified perspective of the relevant genetic and molecular alterations of this type of lymphoma, that in our opinion, is not available to date.

Abstract

Anaplastic large cell lymphoma (ALCL) is a subtype of CD30+ large T-cell lymphoma (TCL) that comprises ~2% of all adult non-Hodgkin lymphomas. Based on the presence/absence of the rearrangement and expression of anaplastic lymphoma kinase (ALK), ALCL is divided into ALK+ and ALK-, and both differ clinically and prognostically. This review focuses on the historical points, clinical features, histopathology, differential diagnosis, and relevant cytogenetic and molecular alterations of ALK- ALCL and its subtypes: systemic, primary cutaneous (pc-ALCL), and breast implant-associated (BIA-ALCL). Recent studies have identified recurrent genetic alterations in this TCL. In systemic ALK- ALCL, rearrangements in DUSP22 and TP63 are detected in 30% and 8% of cases, respectively, while the remaining cases are negative for these rearrangements. A similar distribution of these rearrangements is seen in pc-ALCL, whereas none have been detected in BIA-ALCL. Additionally, systemic ALK- ALCL—apart from DUSP22-rearranged cases—harbors JAK1 and/or STAT3 mutations that result in the activation of the JAK/STAT signaling pathway. The JAK1/3 and STAT3 mutations have also been identified in BIA-ALCL but not in pc-ALCL. Although the pathogenesis of these alterations is not fully understood, most of them have prognostic value and open the door to the use of potential targeted therapies for this subtype of TCL.

A population-based study of breast implant illness

Background

Despite evidence supporting the safety of breast implants, some women associate their implants with adverse health effects and have called this syndrome “breast implant illness.” We sought to characterize breast implant illness symptoms and to report how implant removal affects their symptoms.

Methods

An anonymous 20 question survey was administered to the Facebook group: “UTAH Breast Implant Illness” to characterize the symptoms these women attributed to their breast implants. Several questions allowed us to evaluate how implant removal affected women’s symptoms.

Results

Of the 182 respondents, 97% report that implants negatively affect their health and 95% identify these symptoms with breast implant illness. Ninety-six percent of respondents had implants placed for cosmetic reasons and 51% had silicone implants. The most common symptoms associated with breast implant illness are brain fog (95%), fatigue (92%), joint pain (80%), and hair loss (74%). Sixty percent of respondents learned about breast implant illness from family/friends and/or social media platforms (56%), 40% of respondents had their implants removed, and 97% report relief of their symptoms post-removal (23% complete, 74% partial). Following explantation, there was a significant improvement in all but one reported symptom. An association was found between the number of symptoms reported prior to explantation and the number of symptoms resolving following explantation.

Conclusions

Breast implant illness is a syndrome characterized by fatigue, decreased focus, hair loss, and joint pain after the placement of breast implants. Nearly all patients report improvement of symptoms after implant removal. Significant efforts should be made to better understand breast implant illness and its etiology.

The Prevalence of Self-Reported Health Complaints and Health-Related Quality of Life in Women With Breast Implants

Background

Some of the millions of women with silicone breast implants (SBIs) report a pattern of systemic complaints, known as ASIA syndrome. However, the association between these complaints and breast implants remains uncertain.

Objectives

This study aimed to evaluate the prevalence of complaints in women with breast implants and healthy controls, and to compare their health-related quality of life.

Methods

Four groups of subjects were requested to fill in a general and a diagnostic questionnaire, and the Short Form 36. Group 1 was recruited from the Dutch foundation for breast implant illness (BII). Two groups were recruited from Dutch hospitals, where they had been augmented or reconstructed with SBIs (group 2) or saline-filled and hydrogel implants (group 3). A control group without breast implants was recruited from friends of subjects from group 2.

Results

In total, 238 women completed the questionnaires. ASIA manifestations appeared in the majority of the respondents (72.3%-98.8%), with a latency period of 0 to 35 years. Adjusted for age, smoking, and comorbidities, typical symptoms only occurred significantly more frequently in group 1. The presence of a chronic disease was an independent predictor for ASIA syndrome. The health-related quality of life was lower in women with SBIs than in women without breast implants.

Conclusions

The adjusted prevalence of BII manifestations is not significantly higher in women with SBIs than in women without implants. The findings of this study suggest that results on BII are subject to selection bias. Further studies are needed to prove an association between self-reported complaints and SBIs.

Understanding Breast Implant Illness, Before and After Explantation: A Patient-Reported Outcomes Study

Background

Breast implant illness (BII) after aesthetic breast augmentation remains a poorly defined syndrome encompassing a wide spectrum of symptoms. While previously published series have observed overall symptomatic improvement after breast implant removal,^1–3 there is a lack of studies evaluating changes in specific symptoms over time. The purpose of this study was to gain an understanding of symptoms associated with BII, and to evaluate how these symptoms change after removal of breast implants and total capsulectomy (explantation). We hypothesized that patients presenting with BII would experience both immediate and sustained improvement in constitutional symptoms after explantation.

Methods

A retrospective study of all patients who underwent explantation by a single surgeon over 2 years was conducted. Repeated-measures analysis of variance accounting for dependency was used to compare symptoms before and after surgery. Multivariate analyses and linear regression models were used to examine the impact of patient- and implant-related factors on changes in symptoms.

Results

Seven hundred fifty patients met inclusion criteria. Mean preoperative survey score (26.19 ± 11.24) was significantly different from mean postoperative survey score at less than 30 days (9.49 ± 7.56) and greater than 30 days (9.46 ± 7.82, P < 0.001). Patients with a BMI greater than 30 or those with clinically detectable contracture on examination showed greater improvement on their survey scores (P = 0.039, 0.034, respectively).

Conclusions

Although BII encompasses a large range of symptoms, subjects in this study demonstrated significant and sustained improvement in 11 common symptom domains. This improvement was demonstrable within the first 30 days postoperatively and was maintained beyond 30 days. The study demonstrated a strong association of explantation and specific symptom improvement within the patient population studied. Future investigation will further elucidate possible biologic phenomena to better characterize the pathophysiology and mechanism of BII.

Subjective Cognitive Functioning in Silicone Breast Implant Patients: A Cohort Study

Cognitive impairment is frequently reported by silicone breast implant (SBI) patients. The aim of our study is to investigate whether subjective cognitive failure indeed is more frequent in a cohort of SBI patients compared with healthy controls (HCs). Furthermore, the severity of this cognitive failure and a possible relation to other symptoms as well as the duration of SBI exposure was examined. In addition, we assessed the effect of ruptures and reinterventions on cognitive failure severity.

Methods

A cohort study was performed, including 376 women and consisting of 3 different groups of patients; 143 SBI patients (group 1), 94 age- and sex-matched HC patients (group 2), and 139 women with SBI and health issues who registered themselves at a Dutch foundation for women with illness due to SBI (group 3). All patients filled in the Cognitive Failure Questionnaire (CFQ). The American College of Rheumatology Fibromyalgia Diagnostic Criteria (2010) were used to score other symptoms.

Results

Completed CFQ data from 222 patients were available for analysis: n = 79 for group 1, n = 62 for group 2, and n = 81 for group 3. SBI patients from group 3 had a significantly higher prevalence of subjective cognitive dysfunction (CFQ score ≥ 43) compared with SBI patients from group 1 and HC (60.5% versus 13.9% and 12.9%; P = 0.000). Linear regression showed a statistically significant relation between subjective cognitive functioning scores and other symptoms (P = 0.000). Implant duration as well as rupture rate and reinterventions were not found to significantly influence CFQ scores.

Conclusion

An increased risk of cognitive failure in consecutive SBI patients when compared with HCs could not be found.

ASIA syndrome symptoms induced by gluteal biopolymer injections: Case-series and narrative review

Background

The number of plastic surgery procedures have been rising in the last few years. The morbi-mortality due to illegal use of biopolymers is a public health problem. One of the clinical consequences, foreign body modelling reaction, may be a precursor of ASIA (Autoimmune/Inflammatory disease induced by adjuvants) syndrome.The objective of this article is to present a case-series study of patients who developed ASIA syndrome following gluteal injection with biopolymers and emphasize the importance of toxic exposure in triggering autoimmune responses. A surgical technique used on some of the patients in the study is described.

Methods

A group of thirteen patients, diagnosed with foreign body modelling reaction, who developed ASIA syndrome confirmed by approved criteria was followed between May 2016 and May 2018. The "Butterfly Wings Technique," a new surgical procedure for patients who have medium to severe compromise, was used on five of them.A narrative literature review was done to look for subjects with ASIA syndrome and gluteal biopolymer infiltration.

Results

All the patients in the present case-series with foreign body modelling reaction developed ASIA syndrome. Some of them had a background of familial autoimmunity. Five of the patients were surgically treated and saw a clinical improvement after the extraction of the biopolymer with the proposed technique.The narrative literature review identified 7 articles related to the disease through the database search.

Conclusions

We suggest that foreign body modelling reaction should be considered a precursor to ASIA syndrome. New research projects will be needed in the future to evaluate the factors that determine when ASIA syndrome is triggered in a patient with this reaction.

Autoimmune inflammatory syndrome induced by adjuvants (silicone breast implants and lip fillers)

Introduction: Silicone breast implants (SBI) have been used since 1962 in the reconstruction of post-mastectomy cases, in augmentation of the breast, or for cosmetic purposes, while fillers with biopolymer (FB) have been used since the 1990s. Today, they are considered adjuvants of the immune system. Most complications of SBI and FB are local in nature, but some patients experience systemic symptoms, which are defined as adjuvant-induced autoimmune inflammatory syndrome (ASIA). Aim: The aim of this study is to demonstrate the possible association of silicone breast implants and FB with the development of immune-mediated inflammatory rheumatic diseases (IMIRD). Material and methods: The research represents retrospective study which involved 15 female patients with immune-mediated inflammatory rheumatic diseases, 6 of whom were patients with implanted silicone breast implants for cosmetic reasons, and 9 patients with placement of fillers with biopolymer on the lips. Results: The average time from silicone implantation to the onset of the first symptoms was 6.10 ± 5.3 (range 6 months to 24 years). The following immune-mediated inflammatory rheumatic diseases were recorded: 3 patients with systemic sclerosis (SSc), 3 patients with undifferentiated arthritis, 3 patients with seropositive rheumatoid arthritis, 1 patient with systemic lupus erythematosus, 2 patients with undifferentiated SCTD, 2 patients with mixed connective tissue disease, and one patient with unexplained systemic disease. Seven patients had the Raynaud phenomenon. Spontaneous abortions were reported in 2 patients. Conclusion: Earlier reports that silicone breast implants and biopolymer fillers are safe, today are changing with the description of ASIA syndrome.

Classical Examples of the Concept of the ASIA Syndrome

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.

Breast Prosthesis Syndrome: Pathophysiology and Management Algorithm

The cosmetic use of devices like prostheses to increase breast volume is nothing new. It is calculated that millions of people have been exposed to silicone in several ways, including breast implants, and since 1964 there has been uncertainty regarding their safety. We did not find in the literature any studies that reported the appearance of a specific immunological disease in patients with silicone breast implants. Furthermore, there are also neither case-control studies nor reports of patients proving that symptoms of autoimmune/inflammatory syndrome induced by adjuvants (ASIA) occurred after the placement of silicone implants nor that the patients had pre-existing symptoms. Several studies link silicone to allergic reactions and the development of systemic autoimmune diseases; however, other studies deny this association. There are currently several theories about the effect of silicone on the body. One theory with greater acceptance proposes an adjuvant effect of silicone on the development of autoimmune diseases in genetically predisposed patients. However, the variety of symptoms occurring in patients who develop these pathologies leads to doubts about the relationship between the adjuvant effects of a silicone prosthesis may have with a specific autoimmune disease or a mix of these diseases. The lack of consensus on this topic obliges a full review of what has already been reported in the literature to integrate the knowledge and propose a focus for new research on this matter.

Low molecular weight silicones induce cell death in cultured cells

Women with silicone gel-filled breast implants are exposed to organosilicon compounds, in particular methylsiloxanes, as a result of ‘gel bleed’ and implant rupture. Although these silicones were originally considered to be inert, increasing evidence indicates that they can cause serious health problems. Here, we have analyzed the effects of microdroplets of the methylcyclosiloxanes, in particular D4, on the viability of cultured human cells. The exposure of Jurkat suspension and HeLa monolayer cells to D4 resulted in morphological changes of the cells. The analysis of molecular markers for apoptotic and necrotic processes not only demonstrated that caspases were activated and DNA was fragmented in Jurkat cells exposed to D4, but that also the permeability of the plasma membrane was altered. The induction of apoptotic pathways by D4 was substantiated by the inhibition of caspase activation in cells overexpressing Bcl-2. Cleavage of the caspase-3 substrate U1-70K appeared to be dependent on the D4 content and the efficiency of cleavage decreased with increasing size of the methylcyclosiloxanes (D4, D5 and D6). In addition to Jurkat cells, D4-induced U1-70K cleavage was also observed in HeLa cells, but not in HEp-2 cells. Taken together, these results indicate that D4 and, to a lesser extent, D5 can activate cell-death-related pathways in a cell type-specific fashion and suggest that this phenomenon may contribute to the development of Breast Implant Illness.

Autoimmune syndrome induced by adjuvants after breast enhancement with polyacrylamide hydrogel: a study in Poland

Autoimmune syndrome induced by adjuvants (ASIA) is the spectrum of diseases in which the substances considered inert to the body induce autoimmune reactions and inflammation. Some of the biomaterials recently used in plastic surgery, such as silicone or polyacrylamide hydrogel (PAAG) seem to trigger clinical features of ASIA. The aim of this study was to assess the incidence of these features within a group of women after breast augmentation with PAAG. As many as 30 consecutive patients (26–59 years, mean age 39.5) referred to the Clinic of Plastic Surgery after breast enhancement with PAAG were examined. The validated criteria of ASIA syndrome were employed. Descriptive statistics were chosen based on the distribution of variables. The research was approved by the Bioethical Committee of the Centre of Postgraduate Medical Education in Warsaw, Poland. Within the studied group, 50% of patients (n = 15) fulfilled ASIA diagnostic criteria. Apart from local complications, we encountered various general symptoms, among which fever (n = 13, 43.3%), tingling and numbness of upper extremities (n = 10, 33.3%) and chronic fatigue (n = 9, 30%) were the most common. These symptoms were present on an ambulatory visit, before qualification to the operation of hydrogel removal. All patients undergoing surgical PAAG removal (n = 8) declared alleviation or complete resolution of the symptoms. Polyacrylamide hydrogel breast filling, although limiting the invasiveness of the procedure in relation to silicone breast implants, also carries the risk of developing ASIA symptoms. The removal of PAAG may bring improvement in some cases.

Performing laparoscopic sleeve gastrectomy in an obese patient with systemic lupus erythematosus undergoing long-term steroid therapy: a case report

BACKGROUND

Systemic lupus erythematosus (SLE), an autoimmune disease characterized by systemic inflammatory lesions, is often associated with obesity. Obesity aggravates symptoms of SLE; however, these symptoms can be improved by weight loss through diet therapy and bariatric surgery. However, there are only a few reports regarding the effectiveness of bariatric surgery in obese patients with SLE. Herein, we discuss the laparoscopic sleeve gastrectomy (LSG) performed in an obese patient with SLE while undergoing long-term steroid therapy.

CASE PRESENTATION

A 36-year-old female, suffering from SLE for 10 years with effects on the central nervous system, developed diabetes mellitus (DM) triggered by the steroid therapy for SLE. The patient was undergoing steroid therapy (6 mg/day) for SLE since a long time. For DM management, her HbA1c level was maintained at 7.4%. She was 158 cm tall and 91.6 kg in weight. Her body mass index was 36.7. She could not work and depended on welfare services. To improve her obesity and DM, physicians suggested that she should undergo bariatric surgery in our hospital. Eventually, she underwent LSG, which lasted for 185 min, with minimal blood loss and without complications. Her blood glucose level stabilized immediately after the surgery; hence, her antidiabetic medication was discontinued. She was discharged 8 days after surgery, and her weight decreased steadily. In the first year after surgery, her weight was 54.4 kg, and she had lost approximately 37 kg from her initial weight. Her steroid requirement had also reduced to 4 mg/day. Through weight loss, she could begin to work and became a part of society again.

CONCLUSION

LSG was safely performed in an obese patient with SLE undergoing long-term steroid therapy. We noted substantial weight loss, improved DM condition, and reduced requirement of SLE therapy after surgery. Hence, surgical risks must be carefully examined before patients undergo bariatric surgery.
