Abstract
INTRODUCTION Endoscopy prior to bariatric surgery is not always performed, and in sleeve gastrectomy (SG), the surgical specimen is not always sent for pathological examination. There is limited data on the frequency of clinically significant findings in SG specimens or correlation with preoperative endoscopy. METHODS We reviewed 426 consecutive SG patients to determine the concordance of preoperative endoscopy findings in patients with clinically significant postoperative pathology. RESULTS Preoperative endoscopy was performed on 397 patients (93.2%). Three hundred seventy-three patients had preoperative endoscopy and surgical pathology results available. Then, 20/373 (5.4%) patients had potentially significant postoperative pathology, including intestinal metaplasia, autoimmune metaplastic atrophic gastritis (AMAG), gastrointestinal stromal tumors, and/or gastric cancer. The overall incidence of AMAG in the entire cohort was 2.3%. Preoperative gastric biopsies (to include gastric body) identified AMAG in nearly 1/2 of patients. Patients with clinically significant postoperative pathology results had a median [interquartile range] of 3 [3-5] tissue blocks examined as compared to 3 [1-3] for the remainder of the cohort (p < 0.001). CONCLUSION This is one of the largest studies describing clinically significant postoperative pathology after SG. AMAG, in particular, is of particular importance as it is associated with a 3-fivefold increase in risk for gastric cancer. The incidence of significant postoperative pathology in this population is small but potentially clinically significant and requires validation in larger studies. We recommend wider sampling in preoperative endoscopy (body and antrum), especially in patients being planned for gastric bypass, consideration for routine pathological examination of SG surgical specimens, with careful gross examination and targeted sampling.

Abstract
Inflammatory disorders of the brain and spine have a highly variable MRI appearance, often demonstrating significant overlap in imaging features. The resulting diagnostic dilemma is particularly challenging when considering the more uncommon neuroinflammatory entities. Diligent examination of the salient clinical presentation and signal alteration on imaging examination is necessary when considering neuroinflammation as a diagnostic possibility and may aid in raising suspicion for a particular neuroinflammatory entity. This article reviews a selection of uncommon and miscellaneous inflammatory disorders of the brain and spine to raise awareness of the clinical and imaging features that may assist in this challenging diagnostic task.

Abstract
NLRP inflammasomes are a group of cytosolic multiprotein oligomer pattern recognition receptors (PRRs) involved in the recognition of pathogen-associated molecular patterns (PAMPs) and danger-associated molecular patterns (DAMPs) produced by infected cells. They regulate innate immunity by triggering a protective inflammatory response. However, despite their protective role, aberrant NLPR inflammasome activation and gain-of-function mutations in NLRP sensor proteins are involved in occurrence and enhancement of non-communicating autoimmune, auto-inflammatory, and neurodegenerative diseases. In the last few years, significant advances have been achieved in the understanding of the NLRP inflammasome physiological functions and their molecular mechanisms of activation, as well as therapeutics that target NLRP inflammasome activity in inflammatory diseases. Here, we provide the latest research progress on NLRP inflammasomes, including NLRP1, CARD8, NLRP3, NLRP6, NLRP7, NLRP2, NLRP9, NLRP10, and NLRP12 regarding their structural and assembling features, signaling transduction and molecular activation mechanisms. Importantly, we highlight the mechanisms associated with NLRP inflammasome dysregulation involved in numerous human auto-inflammatory, autoimmune, and neurodegenerative diseases. Overall, we summarize the latest discoveries in NLRP biology, their forming inflammasomes, and their role in health and diseases, and provide therapeutic strategies and perspectives for future studies about NLRP inflammasomes.

Abstract
Background No reports of organ donation have been documented in patients suffering from severe autoimmune glial fibrillary acidic protein (GFAP) astrocytopathy. Case presentation A 27-year-old male patient developed a fever and headache, followed a week later by weakness and unsteadiness in his limbs. He attended his local hospital, but no cause was found. Thirteen days later, he became unconscious and was promptly moved to the intensive care unit for symptomatic support treatment, with no improvement. He was then transferred to our hospital, where he suffered a cardiac arrest on the same day. The family abandoned treatment and opted for organ donation, for financial reasons. Cell-based assays demonstrated GFAP antibodies in the cerebrospinal fluid. Two kidney recipients and one liver recipient showed no abnormal reactions 15 months after receiving organ transplants. Conclusions We report a case of organ donation following brain death in a patient diagnosed with GFAP astrocytopathy, highlighting the need for vigilance regarding the potential occurrence of cardiac arrest in patients with this condition. Considering the potential of GFAP astrocytopathy is crucial when observing deteriorating symptoms, seizures, and consciousness disturbances subsequent to a suspected viral infection. Successful organ donation from patients with GFAP astrocytopathy may be feasible given the exclusion of systemic infection and the absence of peripheral organ involvement.

Abstract
Alopecia areata (AA) is an autoimmune condition that causes non-scarring hair loss on the scalp or other hair-bearing surfaces. Various signalling molecules regulate the hair cycle and hair follicle regeneration. These include genes, growth factors, nuclear receptors, cytokines, and subcellular signalling pathways. Growth factors can cause the vascular endothelium and dermal fibroblasts to proliferate, extend the anagen phase, and delay the initiation of catagen in the hair follicle, thereby promoting hair growth. Microneedling causes the release of growth factors and has been shown to help high-molecular-weight drugs penetrate the stratum corneum and hair follicles. These recent discoveries regarding the pathogenesis of AA have resulted in the development of promising therapies. Herein, this article reviews the use of growth factors and microneedling in the treatment of AA and explores their efficacy and safety. Treatment with growth factors and microneedling appears to be highly effective for AA, with no major adverse effects, and may provide a new option for hair regeneration therapy. To support the efficacy of growth factors and microneedling for AA treatment, additional large-scale studies of patients with AA are needed.

Abstract
Thyroid eye disease (TED) is an autoimmune condition affecting the orbit and the eye with its adnexa, often occurring as an extrathyroidal complication of Graves' disease (GD). Orbital inflammatory infiltration and the stimulation of orbital fibroblasts, triggering de novo adipogenesis, an overproduction of hyaluronan, myofibroblast differentiation, and eventual tissue fibrosis are hallmarks of the disease. Notably, several redox signaling pathways have been shown to intensify inflammation and to promote adipogenesis, myofibroblast differentiation, and fibrogenesis by upregulating potent cytokines, such as interleukin (IL)-1β, IL-6, and transforming growth factor (TGF)-β. While existing treatment options can manage symptoms and potentially halt disease progression, they come with drawbacks such as relapses, side effects, and chronic adverse effects on the optic nerve. Currently, several studies shed light on the pathogenetic contributions of emerging factors within immunological cascades and chronic oxidative stress. This review article provides an overview on the latest advancements in understanding the pathophysiology of TED, with a special focus of the interplay between oxidative stress, immunological mechanisms and environmental factors. Furthermore, cutting-edge therapeutic approaches targeting redox mechanisms will be presented and discussed.

Abstract
PURPOSE We present two cases of autoimmune hypothyroidism converted to Graves' disease (GD) and their medical management. METHODS We tested thyroid function and thyroid antibodies and performed an ophthalmologic examination and neck ultrasound in two patients with autoimmune hypothyroidism converted to GD during a follow-up of several years. CASE REPORTS The first case is a 33 year-old woman with hypothyroidism due to Hashimoto's thyroiditis (HT). She developed signs and symptoms of hyperthyroidism after 7 years of treatment with the same dose of levothyroxine (LT4). Even when LT4 therapy was discontinued, she remained thyrotoxic, with mild Graves' ophthalmopathy (GO) and very high thyroid-stimulating hormone receptor antibodies (TRAb > 40 IU/L, reference range: <1.75 IU/L). Antithyroid medication was started on a titration regimen, without achievement of euthyroidism. She was switched to a block and replace regimen, using 20 mg of methimazole (MMI) and 75 mcg of LT4 daily, with normalization of thyroid hormones and improvement of GO without steroids. The second case is a 57 year-old man with a 2-year positive medical history of HT and 6 months of LT4 treatment. He developed hyperthyroidism and moderate-severe GO. Despite stopping LT4 and initiating antithyroid medication in a titration regimen, he did not achieve euthyroidism and had active GO. Pulse glucocorticoid therapy and switching to a block-replace regimen was required to achieve euthyroidism and reduce ocular proptosis and diplopia. CONCLUSION Spontaneous autoimmune conversion of hypothyroidism to hyperthyroidism can occur at any time: it is important to promptly identify these cases so as to manage them effectively.

Abstract
Autoimmune-mediated obsessive-compulsive disorder (OCD) can occur in multiple sclerosis (MS). Here, a well-studied case study of a patient with OCD and MS-compatible diagnostic findings is presented. The 42-year-old female patient had displayed OCD symptoms for 6 years. Magnetic resonance imaging (MRI) identified several periventricular and one brainstem lesion suggestive of demyelination. Cerebrospinal fluid (CSF) analyses detected an increased white blood cell count, intrathecal immunoglobulin (Ig) G and IgM synthesis, CSF-specific oligoclonal bands, and a positive MRZ reaction. Neopterin was increased, but sarcoidosis was excluded. In the absence of neurological attacks and clues for MRI-based dissemination in time, a radiologically isolated syndrome, the pre-disease stage of MS, was diagnosed. Neurotransmitter measurements of CSF detected reduced serotonin levels. In the absence of visible strategic demyelinating lesions within the cortico-striato-thalamo-cortical circuits, OCD symptoms may relate to reduced intrathecal serotonin levels and mild neuroinflammatory processes. Serotonin abnormalities in MS should be studied further, as they could potentially explain the association between neuroinflammation and mental illnesses.

Abstract
Autoimmune gastrointestinal (GI) disorders comprise a heterogeneous group of diseases with non-specific clinical manifestations. These are divided into primary and secondary. A high index of clinical suspicion complemented with endoscopic and radiological imaging may allow early diagnosis. Due to the relatively low incidence of autoimmune disorder, the imaging literature is sparse. In this review, we outline the pathogenesis, classification, and imaging appearances of autoimmune GI disorders.

Abstract
PURPOSE OF REVIEW This review aims to explore the underlying mechanisms that lead to hypertension in glomerular diseases and the advancements in treatment strategies and to provide clinicians with valuable insights into the pathophysiological mechanisms and evidence-based therapeutic approaches for managing hypertension in patients with glomerular diseases. RECENT FINDINGS In recent years, there have been remarkable advancements in our understanding of the immune and non-immune mechanisms that are involved in the pathogenesis of hypertension in glomerular diseases. Furthermore, this review will encompass the latest data on management strategies, including RAAS inhibition, endothelin receptor blockers, SGLT2 inhibitors, and immune-based therapies. Hypertension (HTN) and cardiovascular diseases are leading causes of mortality in glomerular diseases. The latter are intricately related with hypertension and share common pathophysiological mechanisms. Hypertension in glomerular disease represents a complex and multifaceted interplay between kidney dysfunction, immune-mediated, and non-immune-mediated pathology. Understanding the complex mechanisms involved in this relationship has evolved significantly over the years, shedding light on the pathophysiological processes underlying the development and progression of glomerular disease-associated HTN, and is crucial for developing effective therapeutic strategies and improving patients' outcomes.

Abstract
BACKGROUND Eosinophilic fasciitis (EF) is a rare disease characterized by skin induration and musculoskeletal abnormalities. Diagnostic criteria for EF are based on adult populations. There is a need to expand the literature on EF in children due to limited reported cases and potential differences compared to adults. METHODS We conducted a retrospective review of medical records for six pediatric patients diagnosed with EF at our institution between November 2011 and April 2023. Inclusion criteria required patients to be under 18 years of age at the time of diagnosis and to have confirmed diagnosis through clinical history, imaging, and histology. RESULTS Most of our cohort were female (83%) and non-Hispanic white (50%). Age at diagnosis ranged from 4 to 16 years. Duration of symptoms before diagnosis varied from 1 to 12 months. Follow-up periods ranged from 14 to 123 months. Concurrent medical conditions included localized scleroderma, acquired thrombophilia, and juvenile idiopathic arthritis. Patients presented with progressive painful swelling, severe joint limitations, and positive prayer sign. Initial regimens involved corticosteroids and methotrexate. Hydroxychloroquine, immunoglobulin, mycophenolate mofetil, rituximab, and tocilizumab were also used depending on the patient's disease severity and course. CONCLUSIONS Juvenile EF may manifest as swelling and progressive induration without apparent skin abnormalities. Unlike adult populations, no underlying malignancies or associations with trauma were observed in our cohort. Our cases did not exhibit systemic involvement observed in previous studies on juvenile EF. While non-specific, the prayer sign may aid in early recognition of juvenile EF and help prevent long-term disability.

Abstract
BACKGROUND Diabetes mellitus (DM) is an autoimmune manifestation defined by persistent hyperglycemia and alterations in protein, fatty substances, and carbohydrate metabolism as an effect of problems with the secretion of insulin action or both. Manifestations include thirst, blurred eyesight, weight loss, and ketoacidosis, which can majorly lead to coma. There are different types of diabetes according to class or by cellular level. They are interrelated with hyperlipidemia as they are involved in the metabolism and regulation of physiological factors. Most parameters are seen at cellular or humoral levels, yet the underlying concern remains the same. OBJECTIVE To create a systematic correlation between the disease and locate the exact mechanism and receptors responsible for it. So, this article covers a proper way to resolve the conditions and their manifestation through literacy and diagrammatic. CONCLUSION Hence, this will be an insight for many scholars to understand the exact mechanism involved in the process.

Abstract
Rheumatoid arthritis (RA) is one of over 100 different types of autoimmune conditions. In RA, the cells of the immune system attack the tissue lining the joints, triggering inflammation. A large body of research suggests that the underlying trigger(s) of RA are unique to an individual. For example, increased risk of RA can be driven by smoking tobacco in one individual and mercury exposure in another. Due to the development of next-generation sequencing technology, the critical role of the microbiota in shaping RA risk has been elucidated. Therefore, it is surprising that diet, arguably the most important lever in shaping the gut microbiota, is ineffective in the treatment of RA, even in a sub-set of patients. To attempt to rationalise this apparent paradox, we conducted an umbrella review to address the question as to whether diet can affect outcomes in RA.

Abstract
BACKGROUND Autoimmune hemolytic anemia (AIHA) is a rare, life-threatening disease in pediatrics. This article describes the clinical features, diagnostic workup, treatment and outcome in patients with AIHA. METHOD Medical charts of under 18-year-old patients with AIHA treated at a tertiary Brazilian institution from 2006 to 2021 were retrospectively reviewed. Data analysis was primarily descriptive, using medians, interquartile ranges, and categorical variables presented as absolute frequencies. MAIN RESULTS Twenty-four patients (14 female, 10 male) were evaluated in this study. The median age at diagnosis was 5.99 years (range: 0.25-17.1 years) and the median hemoglobin level was 4.85 g/dL (range: 4.17-5.57 g/dL). Most had warm antibodies (83.3 %). Twelve patients (50 %) had known underlining diseases, four (16.6 %) presented with AIHA concomitant with acute infectious diseases and three (12.5 %) had an undetermined post-vaccine association. Steroids and intravenous immunoglobulin were first-line therapy in 23 cases. Seven patients (29.1 %) required second and third-line treatments (rituximab, cyclophosphamide and splenectomy). The median follow-up period was 4.4 years (range: 1.0-6.7 years). Thirteen patients (54.1 %) were discharged, five cases (20.8 %) were lost to follow-up and no patient died. The median age for the six remaining patients was 11.53 years (8.5-14.7) with all of them having complete responses with no further therapies. CONCLUSION Most cases of AIHA are secondary to an underlying systemic disease or have a possible correlation with infections/vaccines and respond to steroids. The second and third-line therapies for refractory and relapse cases remain a dilemma. A prospective, multicenter study is essential to address the best therapeutic combinations.

Abstract
BACKGROUND Although there are many possible causes for cervical dystonia (CD), a specific etiology cannot be identified in most cases. Prior studies have suggested a relationship between autoimmune disease and some cases of CD, pointing to possible immunological mechanisms. OBJECTIVE The goal was to explore the potential role of multiple different immunological mechanisms in CD. METHODS First, a broad screening test compared neuronal antibodies in controls and CD. Second, unbiased blood plasma proteomics provided a broad screen for potential biologic differences between controls and CD. Third, a multiplex immunoassay compared 37 markers associated with immunological processes in controls and CD. Fourth, relative immune cell frequencies were investigated in blood samples of controls and CD. Finally, sequencing studies investigated the association of HLA DQB1 and DRB1 alleles in controls versus CD. RESULTS Screens for anti-neuronal antibodies did not reveal any obvious abnormalities. Plasma proteomics pointed towards certain abnormalities of immune mechanisms, and the multiplex assay pointed more specifically towards abnormalities in T lymphocytes. Abnormal immune cell frequencies were identified for some CD cases, and these cases clustered together as a potential subgroup. Studies of HLA alleles indicated a possible association between CD and DRB1*15:03, which is reported to mediate the penetrance of autoimmune disorders. CONCLUSIONS Altogether, the association of CD with multiple different blood-based immune measures point to abnormalities in cell-mediated immunity that may play a pathogenic role for a subgroup of individuals with CD.

Abstract
INTRODUCTION Chorea is primarily due to an imbalance of basal ganglia output pathways, often due to dysfunction or degeneration of the caudate nucleus and putamen, and can be due to many causes. METHODS We reviewed the recent literature to identify newly-recognized causes of chorea, including auto-immune, metabolic, and genetic. We also focused upon developments in mechanisms relating to underlying pathophysiology of certain genetic choreas and advances in therapeutics. RESULTS Novel autoantibodies continue to be identified as causes of chorea. Both COVID-19 infection and vaccination are reported to result rarely in chorea, although in some cases causality is not clearly established. Advances in genetic testing continue to find more causes of chorea, and to expand the phenotype of known genetic disorders. Deep brain stimulation can be successful in certain circumstances. CONCLUSION Our understanding of mechanisms underlying this movement disorder continues to advance, however much remains to be elucidated.

Abstract
Adipose-derived stem cells (ASCs) are a critical adult stem cell subpopulation and are widely utilized in the fields of regenerative medicine and stem cell research due to their abundance, ease of harvest, and low immunogenicity. ASCs, which are homologous with skin by nature, can treat immune-related skin diseases by promoting skin regeneration and conferring immunosuppressive effects, with the latter being the most important therapeutic mechanism. ASCs regulate the immune response by direct cell-cell communication with immune cells, such as T cells, macrophages, and B cells. In addition to cell-cell interactions, ASCs modulate the immune response indirectly by secreting cytokines, interleukins, growth factors, and extracellular vesicles. The immunomodulatory effects of ASCs have been exploited to treat many immune-related skin diseases with good therapeutic outcomes. This article reviews the mechanisms underlying the immunomodulatory effects of ASCs, as well as progress in research on immune-related skin diseases.

Abstract
OBJECTIVE To discover the common triggers for AIHA in children, their clinical profile, treatment response, and outcome. METHODS This was an ambispective descriptive study conducted between 2013 and 2020. Children aged 1 mo to 14 y with hemolytic anemia and a positive direct antiglobulin test (DAT) were included. Children with a positive DAT but without any clinicolaboratory evidence of hemolysis were excluded. Data were collected from a structured pro forma with particulars comprising clinicolaboratory profile, treatment administered, and disease outcome. RESULTS A total of 46 children (aged between 1 mo and 14 y) were enrolled in the study. The mean age of onset was 8.7 (± 4.34) y, and 24 (52.8%) were males. Secondary causes were observed in 29 (63%) cases, while the primary cause was found in 17 (37%). Systemic lupus erythematosus (SLE) was the common trigger in 13 (45%) cases, followed by malignancy in 4 (14%) cases. Pallor (98%), hepatomegaly (72%), and splenomegaly (48%) were the most commonly observed clinical signs. The mixed immunophenotype was observed in 27 (59%) cases, followed by warm type in 12 (26%) and cold agglutinin type in 7 (15%) cases. All children received glucocorticoid therapy, and mycophenolate mofetil was commonly used as second-line therapy in 15 (33%) cases. 13 cases (71%) of primary AIHA and only 4 (14%) cases of secondary anemia achieved complete remission. Overall, 7 children (15%) died, all belonging to secondary AIHA. CONCLUSION Secondary AIHA was more common than primary in the present study, and SLE was the standard trigger. Primary AIHA carries a better prognosis than secondary.

Abstract
Studies over the last 2 decades have identified IL-17 and IL-21 as key cytokines in the modulation of a wide range of immune responses. IL-17 serves as a critical defender against bacterial and fungal pathogens, while maintaining symbiotic relationships with commensal microbiota. However, alterations in its levels can lead to chronic inflammation and autoimmunity. IL-21, on the other hand, bridges the adaptive and innate immune responses, and its imbalance is implicated in autoimmune diseases and cancer, highlighting its important role in both health and disease. Delving into the intricacies of these cytokines not only opens new avenues for understanding the immune system, but also promises innovative advances in the development of therapeutic strategies for numerous diseases. In this review, we will discuss an updated view of the immunobiology and therapeutic potential of IL-17 and IL-21.

Abstract
Autoimmune hepatitis (AIH) presents a diagnostic challenge because it is relatively rare and heterogenous in presentation. This article presents the currently adopted approach to AIH diagnosis and explores the challenges with accurately identifying this disease entity. AIH offers no pathognomonic findings, instead relies on clinical presentation, serology, and histology to make the diagnosis. Diagnostic scoring systems support clinical judgment and serve as valuable tools in diagnosis and research. Histological analysis remains the cornerstone of diagnosis and to this day biopsy is essential to make the diagnosis.

Abstract
Autoimmune thyroid disease is a complex and highly frequent disease, where a wide variety of genetic, epigenetic and environmental factors (among others) come together and interact, and is characterized by the presence of two clinical outcomes: hypothyroidism (in Hashimoto's thyroiditis) and hyperthyroidism (in Graves-Basedow disease). For its part, differentiated thyroid carcinoma (mainly papillary carcinoma) is the most common type of cancer affecting the thyroid (and one of the most prevalent worldwide). An important co-occurrence between autoimmune thyroid disease and differentiated thyroid carcinoma has been documented. In this article, studies that have evaluated possible associations and relationships between autoimmune thyroid disease and differentiated thyroid cancer are systematically described and summarized. To date, the underlying mechanism that explains this association is inflammation; however, the characteristics and designs of the studies evaluated do not yet allow a causal relationship between the two entities to be established. These aspects have made it difficult to establish "causality" in the continuum of the pathogenesis between both conditions.

Abstract
BACKGROUND Premature ovarian insufficiency (POI) is a relatively common gynecologic endocrine disorder, which is hypogonadism associated with amenorrhea, increased levels of gonadotropins, and hypoestrogenism. POI resulting from ovarian autoimmunity is a poorly understood clinical condition lacking effective treatments. This study is aimed to investigate the therapeutic effect of mesenchymal stem cells (MSCs) on autoimmune premature ovarian insufficiency. METHODS In this study, in vivo and in vitro experiments were conducted to clarify the therapeutic effects and possible mechanisms of human bone marrow-derived MSCs (hBMSCs) on autoimmune POI, and to provide an experimental evidence for the treatment of autoimmune POI by hBMSCs. Noteworthy, in this study, we used interferon-gamma (IFN-γ) to induce autoimmune inflammation in human granulosa cell line KGN, simulating the pathophysiological changes of granulosa cells in autoimmune POI, and therefore sought to establish an in vitro cell model of autoimmune POI, which is still lacking in experimental methodology. RESULTS And we found that, in vitro, co-culture of hBMSCs could promote granulosa cell proliferation, inhibit apoptosis, improve hormone synthesis capacity, and reduce the occurrence of pyroptosis; and in vivo, hBMSCs resulted in improved estrous cycle disorders in autoimmune POI mice, increased serum estradiol, decreased follicle-stimulating hormone, improved ovarian morphology, increased number of primordial and primary follicles, decreased number of atretic follicles, and decreased ovarian granulosa cell apoptosis. CONCLUSIONS hBMSCs have therapeutic effects on autoimmune POI both in vitro and in vivo.

Abstract
INTRODUCTION AND IMPORTANCE Pemphigus Vulgaris (PV) is a low incidence autoimmune mucocutaneous bullous disease, in which pathogenic antibodies are directed against the keratinocyte cell surface. Although anal involvement is unusual, correlations between its appearance and disease severity have been recently reported. CASE PRESENTATION A 42-year-old male presented with an anal fissure and a year of recurrent oral and pharyngeal aphtha. A chemical sphincterotomy with botulinum toxin plus fissurectomy was performed. 3 years later an upper eyelid injury raised suspicion of pemphigus vulgaris (PV), tested negative for specific antibodies. A couple years later, an anal fissure, and suspected Crohn's disease, led to a second intervention. Surgical analysis unveiled characteristics indicative of a vegetating variant of PV. CLINICAL DISCUSSION Anal involvement in PV varies in prevalence, with studies reporting rates between 2 % and 27.98 %. This manifestation often accompanies late disease stages and may indicate severity, notably in association with oral lesions. Patients might not readily discuss anal symptoms, leading to potential underreporting. Anal PV is linked to other lesions (ocular, nasal, genital) and the severity of oral PV. Even when other sites are in remission, anal recurrence can occur. Early recognition and follow-up are crucial, highlighting the need for routine anal examination and confirmatory diagnostics. CONCLUSION PV lesions can present on the skin or mucosa, although oral lesions are the most common site of initial presentation. Anal PV is a diagnostic challenge, and this case illustrates the importance of a careful evaluation.

Abstract
BACKGROUND Coeliac disease is a chronic autoimmune condition associated with intestinal and extraintestinal symptoms. Coeliac Disease is managed through strict adherence to a gluten-free diet, which, though usually effective, is challenging to maintain. This review synthesised qualitative research on the psychosocial experiences of adults living with coeliac disease. METHODS Keyword searches were conducted of the academic databases CINAHL, EMBASE, MEDLINE, PsychINFO, SCOPUS and Web of Science for articles published (2005-2021), followed by forward and backward searches. Thematic synthesis of included articles was carried out on sections reporting findings or results, discussion, conclusions, and supporting data. The inductive thematic synthesis identified descriptive and analytical themes from the included studies. RESULTS Of 1284 records identified, 17 articles from 15 original studies were included in the thematic synthesis. The majority of studies were from Europe (76%), with the remainder from North America and Australia. Data represented 371 adults with coeliac disease (72% female; 17-85 years old, diagnosed < 1-42 years ago) across eight countries. Findings identified six analytical themes relating to the psychosocial experience of coeliac disease: 'Living with ongoing risk'; 'Losing more than gluten'; 'A changed identity'; 'A changed relationship with food'; 'The gluten-free diet creates a multifaceted burden'; and 'Learning how to live well with Coeliac Disease'. CONCLUSIONS Coeliac disease changes adults' psychosocial experiences. Adaptation involves ongoing learning, and development of psychological acceptance facilitates adjustment. Increased public education about coeliac disease may reduce stigma and risk. Psychosocial assessment and support could improve quality of life post-diagnosis.

Abstract
A number of the well-recognized autoimmune and paraneoplastic neurologic syndromes commonly involve the autonomic nervous system. In some cases, the autonomic nerves or ganglia are primary targets of neurologic autoimmunity, as in immune-mediated autonomic ganglionopathies. In other disorders such as encephalitis, autonomic centers in the brain may be affected. The presence of autonomic dysfunction (especially gastrointestinal dysmotility) is sometimes overlooked even though this may contribute significantly to the symptom burden in these paraneoplastic disorders. Additionally, recognition of autonomic features as part of the clinical syndrome can help point the diagnostic evaluation toward autoimmune and paraneoplastic etiologies. As with other paraneoplastic disorders, the clinical syndrome and the presence and type of neurologic autoantibodies help to secure the diagnosis and direct the most appropriate investigation for malignancy. Optimal management for these conditions typically includes aggressive treatment of the neoplasm, immunomodulatory therapy, and symptomatic treatments for orthostatic hypotension and gastrointestinal dysmotility.

Abstract
Impaired autophagy, due to the dysfunction of lysosomal organelles, contributes to maladaptive responses by pathways central to the immune system. Deciphering the immune-inflammatory ecosystem is essential, but remains a major challenge in terms of understanding the mechanisms responsible for autoimmune diseases. Accumulating evidence implicates a role that is played by a dysfunctional autophagy-lysosomal pathway (ALP) and an immune niche in psoriasis (Ps), one of the most common chronic skin diseases, characterized by the co-existence of autoimmune and autoinflammatory responses. The dysregulated autophagy associated with the defective lysosomal system is only one aspect of Ps pathogenesis. It probably cannot fully explain the pathomechanism involved in Ps, but it is likely important and should be seriously considered in Ps research. This review provides a recent update on discoveries in the field. Also, it sheds light on how the dysregulation of intracellular pathways, coming from modulated autophagy and endolysosomal trafficking, characteristic of key players of the disease, i.e., skin-resident cells, as well as circulating immune cells, may be responsible for immune impairment and the development of Ps.

Abstract
Neuroendocrine neoplasms (NENs) are a heterogeneous group of tumors arising from the transformation of neuroendocrine cells in several organs, most notably the gastro-entero-pancreatic system and respiratory tract. The classification was recently revised in the 5th Edition of the WHO Classification of Endocrine and Neuroendocrine Tumors. NENs can rarely spread to the central or peripheral nervous systems. Neurologic involvement is determined by the rare development of paraneoplastic syndromes, which are remote effects of cancer. Mechanisms depend on immunologic response to a tumor, leading to the immune attack on the nervous system or the production of biologically active ("functioning") substances, which can determine humoral (endocrine) effects with neurologic manifestations. Paraneoplastic neurologic syndromes (PNS) are immunologically mediated and frequently detected in small cell lung cancer but rarely seen in other forms of NEN. PNS and Merkel cell carcinoma is increasingly reported, especially with Lambert Eaton myasthenic syndrome. Endocrine manifestations are found in a wide spectrum of NENs. They can develop at any stage of the diseases and determine neurologic manifestations. Patient outcomes are influenced by tumor prognosis, neurologic complications, and the severity of endocrine effects.

Abstract
Thyroid eye disease (TED) is an inflammatory condition involving the periocular and orbital soft tissues, affecting most commonly patients with hyperthyroid disorders. Traditional treatments used for the active phase of the disease range from conservative lubrication for mild symptoms to systemic immunomodulating drugs for moderate-to-severe symptoms. Teprotumumab (Tepezza) is a monoclonal antibody with an inhibitory effect on insulin-like growth factor 1 and is the first Food and Drug Administration (FDA) approved targeted medical therapy for reducing the inflammatory signs and symptoms associated with TED. Two large multicenter, randomized, double-masked, placebo-controlled trials have confirmed the efficacy and safety of teprotumumab in patients with active, moderate-to-severe TED. Recent reports and publications have also demonstrated the efficacy of teprotumumab in a wider range of patients. In this review, we summarize the clinical features and pathophysiology of TED, disease course, and traditional management methods. We further detail the development of teprotumumab, the founding studies that brought it to its FDA approval, adverse events profile, and ongoing as well as future investigations.

Abstract
Paraneoplastic neurologic syndromes (PNSs) are a group of diseases affecting the central and/or peripheral nervous system caused by immune-mediated processes directed toward antigens with shared expression in tumor and neural tissue. Germ cell tumors (GCTs) are associated with PNSs with varied clinical phenotypes. Early diagnosis of PNS is vital to potentially uncover and treat underlying tumors, improving the chances of recovery, and preventing permanent neurologic complications. In this chapter, we outline the pathophysiology and epidemiology of PNS. We briefly provide a summary of GCTs in males and females. We review the neural-specific autoantibodies and PNSs associated with GCTs and their clinical and radiologic accompaniments. We also provide an overview of the treatment and prognosis of these disorders.

Abstract
Although they are relatively rare, the diagnosis of paraneoplastic neurologic syndromes (PNS) can be aided by the identification of neural autoantibodies in patients' serum and cerebrospinal fluid (CSF). They often clinically manifest as characteristic syndromes, including limbic encephalitis, opsoclonus-myoclonus syndrome, paraneoplastic cerebellar degeneration, and paraneoplastic encephalomyelitis. The antibodies are directed either toward intracellular targets, or epitopes on the cell surface. As compared to cell surface antibodies, intracellular paraneoplastic autoantibodies are more classically associated with cancer, most often lung, breast, thymoma, gynecologic, testicular, and/or neuroendocrine cancers. The malignancies themselves tend to be small and regionally contained, attesting to the strength of the immune system in cancer immunosurveillance. Typically, the intracellular antibodies are not directly pathogenic and tend to be associated with PNS that are poorly responsive to treatment. With some notable exceptions, including patients with PNS associated with testicular cancer, patients with intracellular antibodies are typically older individuals, in their 7th decade of life and beyond. Many of them are current or former smokers. Treatment strategies include tumor removal as well as immunotherapy to treat the concomitant PNS. Newer technologies and the ever-broadening use of cancer immunotherapies are contributing to the continued identification of novel intracellularly targeted autoantibodies.

Abstract
Among patients with paraneoplastic neurologic syndromes (PNS), emphasis has historically been placed on neural antibodies against intracellular proteins that have a strong association with malignancy. Because of the intracellular location of their antigenic targets, these antibodies are typically considered to be non-pathogenic surrogate markers of immune cell-mediated neural injury. Unfortunately, patients with these antibodies often have suboptimal response to immunotherapy and poor prognosis. Over the last two decades, however, dramatic advancements have been made in the discovery and clinical characterization of neural antibodies against extracellular targets. These antibodies are generally considered to be pathogenic, given their potential to directly alter antigen structure or function, and patients with these antibodies often respond favorably to prompt immunotherapy. These antibodies also associate with tumors and may thus occur as PNS, albeit more variably than neural antibodies against intracellular targets. The updated 2021 PNS diagnostic criteria, which classifies antibodies as high-risk, intermediate-risk, or lower-risk for an associated cancer, better clarifies how neural antibodies against extracellular targets relate to PNS. Using this recently created framework, the clinical presentations, ancillary test findings, oncologic associations, and treatment responses of syndromes associated with these antibodies are discussed.

Abstract
Paraneoplastic neurological disorders represent a significant part of the field of autoimmune neurology. Most neural autoantibodies discovered to date are associated with underlying malignancy and in that context are considered paraneoplastic antibody biomarkers. These autoantibodies can be divided into two major categories: those that target intracellular proteins (not pathogenic) and those that target plasma membrane proteins (pathogenic). Disorders accompanied by the former are mediated primarily by neural peptide-specific cytotoxic T-cells, are commonly associated with cancer, and are poorly responsive to immunotherapy. Disorders accompanied by the latter represent antibody-mediated diseases and are generally more responsive to immunotherapy. Areas of significant unmet need in the context of paraneoplastic neurological disorders include novel therapeutic options, as FDA-approved therapies are lacking. This chapter provides a brief overview of immunopathological mechanisms and potential future therapeutic targets. Our contributing authors and their chapters are also introduced.

Abstract
New onset movement disorders are a common clinical problem in pediatric neurology and can be infectious, inflammatory, metabolic, or functional in origin. Encephalitis is one of the more important causes of new onset movement disorders, and movement disorders are a common feature (~25%) of all encephalitis. However, all encephalitides are not the same, and movement disorders are a key diagnostic feature that can help the clinician identify the etiology of the encephalitis, and therefore appropriate treatment is required. Movement disorders are a characteristic feature of autoimmune encephalitis such as anti-NMDAR encephalitis, herpes simplex virus encephalitis-induced autoimmune encephalitis, and basal ganglia encephalitis. Other rarer autoantibody-associated encephalitis syndromes with movement disorder associations include encephalitis associated with glycine receptor, DPPX, and neurexin-3 alpha autoantibodies. In addition, movement disorders can accompany acute disseminated encephalomyelitis with and without myelin oligodendrocyte glycoprotein antibodies. Extremely important infectious encephalitides that have characteristic movement disorder associations include Japanese encephalitis, dengue fever, West Nile virus, subacute sclerosing panencephalitis (SSPE), and SARS-CoV-2 (COVID-19). This chapter discusses how specific movement disorder phenomenology can aid clinician diagnostic suspicion, such as stereotypy, perseveration, and catatonia in anti-NMDAR encephalitis, dystonia-Parkinsonism in basal ganglia encephalitis, and myoclonus in SSPE. In addition, the chapter discusses how the age of the patients can influence the movement disorder phenomenology, such as in anti-NMDAR encephalitis where chorea is typical in young children, even though catatonia and akinesia is more common in adolescents and adults.

Abstract
PURPOSE The role of circular RNAs (circRNAs) in type 1 diabetes (T1D) is largely unknown. We aimed to identify some circRNAs as differential diagnostic biomarkers for T1D to discriminate patients with latent autoimmune diabetes in adults (LADA), and type 2 diabetes (T2D). METHODS The circRNA expression profiles were determined by Arraystar human circRNA microarray in T1D compared to controls (n = 6 each). The differentially expressed circRNAs were validated by RT-qPCR using a validation cohort with 20 T1D and 20 controls. The diagnostic performances of the candidate circRNAs and the clinical parameters were assessed using the logistic least absolute shrinkage and selection operator (LASSO) regression model in a larger cohort with 457 subjects including patients with T1D, T2D and LADA, and controls. RESULTS We identified 110 differentially expressed circular transcripts (53 upregulated and 57 downregulated) in T1D patients compared with controls. Further analysis showed that the levels of hsa_circRNA_405498 and hsa_circRNA_100033 were significantly downregulated in T1D compared to controls (both P < 0.05). Moreover, the expression levels of these two circRNAs showed sequential downregulation from controls, patients with T2D, LADA, to T1D (P < 0.05). The area under the curve (AUC) of receiver operating characteristic (ROC) plots in logistic LASSO regression model showed high diagnostic accuracy for combination model with the two circRNAs and some clinical parameters in discriminating T1D from LADA (AUC = 0.915), T2D (AUC = 0.993), and controls (AUC = 0.992). CONCLUSIONS Our study demonstrated that hsa_circRNA_405498 and hsa_circRNA_100033 are promising novel differential diagnostic biomarkers for T1D.

Abstract
BACKGROUND Chronic rhinosinusitis is a very common condition. Granulomatosis with polyangiitis (GPA) and eosinophilic granulomatosis with polyangiitis (eGPA) are systemic diseases which can contribute to the development of chronic rhinosinusitis in select patients. OBJECTIVE Characterize the presenting features, diagnostic criteria, workup, and management of granulomatosis with polyangiitis and eosinophilic granulomatosis with polyangiitis as they are encountered in otolaryngology clinics. METHODS Full length manuscripts published 2000 or later were reviewed. A separate search was conducted for each disease. Pertinent clinical features related to sinonasal manifestations of GPA and eGPA were collected and reported in this review. RESULTS 467 references were discovered during literature review process. In total, 42 references for GPA and 35 references for eGPA were included in this review. CONCLUSION GPA and eGPA are vasculitis syndromes which commonly present in the context of multisystem disease. For GPA, pulmonary and renal disease are common; for eGPA a history of asthma is nearly ubiquitous. Sinonasal disease is a very common feature for both disease processes and may precede the development of systemic symptoms in many patients. Clinical work up and diagnosis is complex and generally requires multidisciplinary care. Treatment primarily consists of immunosuppressive agents, and a number of steroids, steroid sparing agents, and biologics have been shown to be effective. The role of sinus surgery includes tissue biopsy for diagnosis, functional surgery for symptom management in select cases, and reconstruction of cosmetic and functional defects.

Abstract
Coronavirus disease-2019 (COVID-19) is a novel multisystemic viral disease caused pandemic. The disease impact involves liver and associated systems. Undoubtedly, host genetic background influences the predisposition and prediction of infection. Variants among human populations might increase susceptibility or protect against severe outcomes. In this manner, rs738409 variant of patatin-like phospholipase domain-containing protein 3 gene appears to be protective in some populations in spite of its aggravating effect on non-alcoholic fatty liver diseases (NAFLDs) and steatohepatitis. DRB1*15:01 allele of human leukocyte antigen is associated with protective effect in European and Japanese populations. DRB1*03:01 contrarily increases the susceptibility of severe COVID-19 infection in European populations. rs1260326 in glucokinase regulatory protein gene, rs112875651 in tribbles homolog 1 gene, rs429358 in apolipoprotein 1, and rs58542926 in transmembrane 6 superfamily 2 alleles are found related with NAFLD and obesity; thus, hypercoagulability and severe COVID-19 outcomes. In chronic or acute liver diseases, comorbid syndromes are the key factors to explain increased severity. There might not be a direct association between the variant and severe COVID-19 infection. As it is concluded, there are genes and variants known and unknown yet to be studied to reveal the association with disease severity.

Abstract
BACKGROUND Susac syndrome (SuS) is a rare disease characterized by encephalopathy, hearing impairment and visual disturbances. Immunosuppressive treatments are used based on the hypothesis that an autoimmune endotheliopathy drives the disease. However, a solid evidence-based treatment approach is lacking. The aim of this review is to provide an overview of patient characteristics, disease course and treatment patterns related to successful outcome that have been reported in literature since 2013. METHODS Three reviewers conducted a systematic literature search in February 2022. The primary outcome was treatment used, derived from cases classified as probable or definite SuS, describing successful treatment outcome (i.e. no signs of disease activity for ≥ 1 month). Secondary outcomes were time-to-relapse and follow-up time. Published case reports and case series were included. Various clinical characteristics and treatment(s) were extracted and categorized into different phases of treatment. RESULTS A total of 810 records was identified. 120 articles met inclusion criteria and 161 cases were extracted. Of these, 151 cases were classified as probable or definite SuS and included in the final analysis. Number of combinations of treatments used per treatment phase were: 6 empirically, 35 after confirmed diagnosis, 43 for maintenance treatment, 22 after relapse, 18 during maintenance post-relapse. Median follow-up time was 12.3 months (0.5; 120) and median time to relapse was 4 months (1; 120). CONCLUSION This scoping review summarizes treatment approaches in patients with SuS, highlighting variability. International efforts to collect clinical, imaging and treatment data from patients with SuS in registries are needed, in order to provide less biased and long-term follow-up information on treatment response, predictors of relapse and patient outcomes. This may lead to more evidence-based therapeutic approaches.

Abstract
(IgG4-RD) is an immune-mediated fibrotic disorder characterized by severe resolution of inflammation and dysregulation of wound healing. IgG4-RD has been considered a unique disease since 2003, and significant progress has been achieved in the understanding of its essential features. The central role of B cells in IgG4-RD has been demonstrated by the robust clinical responsiveness of IgG4-RD to B cell depletion and the identification of multiple self-antigens that promote B cell expansion. Studies have increasingly revealed critical roles of these B cells and T cells in the pathogenesis of IgG4-RD, and we and other authors further identified CD4+ cytotoxic T lymphocytes as the main tissue-infiltrating CD4+ T cell subset in IgG4-RD tissues. Additionally, T follicular helper cell subsets that play a role in IgG4 isotype switching have been identified. In this review, we discuss research on IgG4-RD and the roles of B cell and T cell subsets, as well as the functions of CD4+ cytotoxic T cells in IgG4-RD pathogenesis. We highlight our findings from ongoing research using single-cell analysis of infiltrating CD4+ cytotoxic T cells, CD4+ follicular helper T cells, and infiltrating B cells in IgG4-RD and propose a model for the pathogenesis of IgG4-RD.

Abstract
OBJECTIVE To review the safety and efficacy of avacopan for the treatment of anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis. DATA SOURCES A systematic review of the literature was performed using the terms avacopan OR tavneos OR CCX168 OR ANCA-associated vasculitis in PubMed and Google Scholar. Articles between January 2016 and January 2023 were considered for inclusion. Bibliographies and ClinicalTrials.gov were also searched for completion. STUDY SELECTION AND DATA EXTRACTION Relative English language and human studies related to pharmacology, clinical trials, and safety were included. DATA SYNTHESIS The 52-week ADVOCATE and 12-week CLEAR clinical trials evaluated the safety and efficacy of avacopan. The remission rate was 65.7% and 54.9% in the avacopan and placebo group, respectively, in the ADVOCATE trial. The Birmingham Vasculitis Activity Score improved by ≥50% in 86.4% of avacopan treated patients and 70% of prednisone treated patients in the CLEAR trial. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE IN COMPARISON WITH EXISTING DRUGS Glucocorticoids in combination with cyclophosphamide, azathioprine, and/or rituximab have been a mainstay of ANCA-associated vasculitis treatment. However, short- and long-term medication-related adverse effects risk negative outcomes for patients. Avacopan may provide equivalent to better treatment with fewer side effects due to a reduction, if not elimination, of glucocorticoids. CONCLUSIONS Avacopan used in isolation or combination is safe and effective for ANCA-associated vasculitis.

Abstract
Introduction Osteoporosis is a common diagnosis and comorbidity observed in patients with rheumatic diseases. It is frequently associated with conditions such as rheumatoid arthritis, spondyloarthropathy, systemic lupus erythematosus, and other autoimmune rheumatic diseases. Conclusion The incidence of osteoporosis is influenced by factors such as uncontrolled disease, prolonged and higher doses of steroid use, immobility, advanced age, and postmenopausal status. Achieving good control of the underlying disease, minimizing or avoiding the use of steroids for extended periods, and ensuring adequate supplementation of vitamin D and calcium are crucial in reducing the incidence of osteoporosis. Regular screening and appropriate management of osteoporosis can significantly decrease the associated morbidity and mortality.

Abstract
BACKGROUND Retinal migraine is a diagnosis of exclusion and is characterized by repeated episodes of transient monocular blindness associated with migraine. We report a case of systemic lupus erythematosus with acute episodes mimicking retinal migraines. CASE REPORT A 46-year-old woman with a history of migraine with aura since her 20s and Evans syndrome presented with episodic transient monocular blindness. Retinal migraine was considered as the cause, and migraine prophylaxis initially reduced its frequency. After 5 months, the frequency increased, with chilblain-like lupus lesions on her extremities. Laboratory testing revealed lymphopenia and hypocomplementemia, fulfilling the diagnostic criteria for systemic lupus erythematosus, which may have caused Evans syndrome and transient monocular blindness, mimicking retinal migraines. After intravenous methylprednisolone and rituximab therapy, the transient monocular blindness episodes did not recur. CONCLUSION Given the clinical presentation, systemic lupus erythematosus should be considered as a cause of transient monocular blindness and should be distinguished from retinal migraine.

Abstract
The high prevalence and rising incidence of autoimmune diseases have become a prominent public health issue. Autoimmune disorders result from the immune system erroneously attacking the body's own healthy cells and tissues, causing persistent inflammation, tissue injury, and impaired organ function. Existing treatments primarily rely on broad immunosuppression, leaving patients vulnerable to infections and necessitating lifelong treatments. To address these unmet needs, an emerging frontier of vaccine development aims to restore immune equilibrium by inducing immune tolerance to autoantigens, offering a potential avenue for a cure rather than mere symptom management. We discuss this burgeoning field of vaccine development against inflammation and autoimmune diseases, with a focus on common autoimmune disorders, including multiple sclerosis, type 1 diabetes, rheumatoid arthritis, inflammatory bowel disease, and systemic lupus erythematosus. Vaccine-based strategies provide a new pathway for the future of autoimmune disease therapeutics, heralding a new era in the battle against inflammation and autoimmunity.

Abstract
Metabolic and autoimmune disorders have long represented challenging health problems because of their growing prevalence in companion animals. The gut microbiome, made up of trillions of microorganisms, is implicated in multiple physiological and pathological processes. Similar to human beings, the complicated microbiome harbored in the gut of canines and felines emerges as a key factor determining a wide range of normal and disease conditions. Evidence accumulated from recent findings on canine and feline research uncovered that the gut microbiome is actively involved in host metabolism and immunity. Notably, the composition, abundance, activity, and metabolites of the gut microbiome are all elements that shape clinical outcomes concerning metabolism and immune function. This review highlights the implications of the gut microbiome for metabolic disorders (obesity, diabetes, and hepatic lipidosis) and autoimmune diseases (inflammatory bowel disease, osteoarthritis, asthma, and myasthenia gravis) in canine and feline animals, providing novel strategies and therapeutic targets for the prevention and treatment of pet diseases.

Abstract
The pathogenesis of autoimmune demyelinating neuropathies is poorly understood compared to inherited demyelinating forms. We performed whole transcriptome (RNA-Seq) using nerve biopsy tissues of patients with different autoimmune and inherited demyelinating neuropathies (CIDP n = 10, POEMS n = 18, DADS n = 3, CMT1 n = 3) versus healthy controls (n = 6). A limited number of differentially expressed genes compared to healthy controls were identified (POEMS = 125, DADS = 15, CMT = 14, CIDP = 5). Divergent pathogenic pathways including inflammatory, demyelinating and neurite regeneration such as with the triggering receptor expressed on myeloid cells (TREM1) part of the immunoglobulin superfamily and RhoGD1 are found. Shared and discordant pathogenic injury are discovered between autoimmune and inherited forms.

Abstract
BACKGROUND Previous serological studies have indicated an association between viruses and atypical pathogens and Chronic Fatigue Syndrome (CFS). This study aims to investigate the correlation between infections from common pathogens, including typical bacteria, and the subsequent risk of developing CFS. The analysis is based on data from Taiwan's National Health Insurance Research Database. METHODS From 2000 to 2017, we included a total of 395,811 cases aged 20 years or older newly diagnosed with infection. The cases were matched 1:1 with controls using a propensity score and were followed up until diagnoses of CFS were made. RESULTS The Cox proportional hazards regression analysis was used to estimate the relationship between infection and the subsequent risk of CFS. The incidence density rates among non-infection and infection population were 3.67 and 5.40 per 1000 person-years, respectively (adjusted hazard ratio [HR] = 1.5, with a 95% confidence interval [CI] 1.47-1.54). Patients infected with Varicella-zoster virus, Mycobacterium tuberculosis, Escherichia coli, Candida, Salmonella, Staphylococcus aureus and influenza virus had a significantly higher risk of CFS than those without these pathogens (p < 0.05). Patients taking doxycycline, azithromycin, moxifloxacin, levofloxacin, or ciprofloxacin had a significantly lower risk of CFS than patients in the corresponding control group (p < 0.05). CONCLUSION Our population-based retrospective cohort study found that infection with common pathogens, including bacteria, viruses, is associated with an increased risk of developing CFS.

Majdi Abunemer R, Saifuddin Shaheen R, Abudullah Alghamdi R. Correlation of anti-TNF-a biological therapy with periodontal conditions and osteonecrosis in autoimmune patients: A systematic review. Saudi Dent J 2023; 35:785-796. [PMID: 38025596 PMCID: PMC10658390 DOI: 10.1016/j.sdentj.2023.07.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [What about the content of this article?

Abstract
Objectives This systematic review aims to investigate the impact of tumor necrotic factor alpha inhibitors in suppressing bone resorption in periodontitis, and its potential to cause osteonecrosis. Extensive electronic research was conducted following the PRISMA guidelines, which connected various aspects of anti-TNF-a (anti-tumor necrosis factor-a) to periodontitis and osteonecrosis patients. Background TNF-a inhibitors are broadly indicated in the treatment of autoimmune patients with possible joint resorption and increased inflammatory processes such as rheumatoid arthritis and inflammatory bowel disease, where they reduce bone loss and certain mediators. As rheumatoid arthritis and periodontitis share many characteristics, these medications may also be helpful in the treatment of coexisting periodontitis. However, besides medical benefits, anti-TNF-a also exhibits several adverse effects, ranging from dizziness to tuberculosis. Osteonecrosis is considered a recent adverse impact. Methods An extensive electronic systematic review following the PRISMA guidelines was performed for English-language papers using the following databases as sources of information: PubMed, Medline, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), Library Genesis, Worldwide Science, National Rheumatoid Arthritis Society (NRAS), and other related articles. This systematic review is registered on the PROSPERO platform under registration number CRD42022341753. Results Twenty articles were identified after the exclusion criteria were applied. These include systematic reviews, case reports, retrospective cohort studies, case report series, meta-analyses, clinical trials, randomised clinical trials, cross-sectional and longitudinal analyses, longitudinal observational studies, and prospective clinical trials. All these were included in the quantitative and qualitative analyses. Conclusions Anti-TNF-a drugs show promising results in treating patients with rheumatoid arthritis and periodontitis but could be considered a risk factor for osteonecrosis. Hence, patients receiving such medications should be closely monitored by the dentist and physician before, during, and after administration.
