Abstract
Multiple factors have engaged in the progression of thyroid cancer (TC). Recent studies have shown that viral infection can be a critical factor in the pathogenesis of TC. Viruses, such as Epstein-Barr virus (EBV), hepatitis C virus (HCV), human immunodeficiency virus (HIV), and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), may play an essential role in the occurrence, development, and even prognosis in TC. This review mainly explored the potential role of viral infection in the progress of TC. The possible mechanisms could be recognizing the host cell, binding to the receptors, affecting oncogenes levels, releasing viral products to shape a beneficial environment, interacting with immune cells to induce immune evasion, and altering the pituitary-thyroid axis. Thus, comprehensive knowledge may provide insights into finding molecular targets for diagnosing and treating virus-related TC.

Abstract
Objectives The objectives were to characterize the liver kidney microsome (LKM) antibody profile of a 14-month-old girl with autoimmune hepatitis and analyze the laboratory prevalence of LKM positivity. Design and methods This is retrospective analysis of the LKM antibody immunofluorescence tests performed by the Immunology Laboratory of Johns Hopkins Hospital from September 8, 2020 to July 31, 2022. LKM positive sera were also tested by an ELISA for LKM1 antibodies, which recognize the cytochrome P450 2D6 antigen. In silico analysis of 2D6 mRNA expression across anatomical sites was performed using Bgee and GTEx Portal databases. Results Of the total of 1598 patients (893 F, 705 M, ages 0.8-94 years) tested for LKM antibodies, 3 were positive, yielding a 0.2% period prevalence. The clinical diagnosis was autoimmune hepatitis in the index case, acute viral hepatitis in a 3-yo male, and hepatocellular carcinoma in a 54-yo male. LKM antibodies yielded the classical homogenous staining pattern in the liver cytosol and proximal kidney tubular cells. The first two patients were also positive for LKM1 antibodies, whereas the third was negative. 2D6 mRNA was expressed highly in the liver, moderately in the duodenum, and minimally in other tissues. Conclusions Overall, LKM antibodies are rare. They contribute to establish a diagnosis of autoimmune hepatitis, although they are also found in other liver diseases. The cytochrome P450 2D6 is one of the antigens recognized by LKM antibodies, but other antigens are likely targeted considering that 2D6 is minimally expressed in the kidney and yet LKM antibodies bind to kidney tubuli.

Abstract
Previous studies have reported that hepatitis C virus (HCV) infection may increase the risk of thyroid disease (TD) even thyroid cancer (TC), but quantitative assessments of risk were rare and the results were not consistent. The purpose of this study was to evaluate the impact of HCV infection on TD and TC, and provide clues to explore the relationship between HCV infection and TD and TC. The literature retrieval was performed up to August 20th, 2021 in the database of PubMed, Cochrane library, Web of Science, China National Knowledge Infrastructure and Wang Fang. The risk of HCV for TD or TC was expressed with odds ratio (OR) and 95% confidence intervals (CI). Subgroup analysis was used to explore the source of heterogeneity. Six articles (three studies published as article and three studies published as abstract) were included in this meta-analysis, with a total of 5398 controls and 1925 cases of hepatitis C. The results of meta-analysis found that HCV infection were significantly associated with an increased risk of TD (sum OR = 1.80, 95% CI = 1.54-2.10, P < 0.001, I2 = 74.3%) and TC (sum OR = 16.36, 95% CI = 4.65-57.62, P < 0.001, I2 = 0%). HCV infection may increase the risk of TD and TC. More work is needed in the future to establish a causal role, however an awareness of the possibility of increased risk of TD and TC may lead to earlier diagnosis and better outcomes in patients with hepatitis C.

Abstract
Down syndrome (DS) is a unique genetic disease caused by the presence of an extra copy of chromosome 21, which carries four of the six interferon receptor (IFN-R) genes on its long arm. Recent studies reporting higher levels of interferon-stimulated gene (ISG) expression in primary immune cells studied ex vivo have suggested that the additional copies of the IFN-R genes in DS result in mild interferonopathy. In this review, we analyze the potential clinical and immunological impacts of this interferonopathy in DS. We performed a literature review to explore the epidemiology and risks of celiac disease, type 1 diabetes, thyroid dysfunction, mucocutaneous manifestations, infectious diseases (including COVID-19), and Alzheimer’s disease in individuals with DS relative to the general population with or without iatrogenic exposure to interferons. We analyzed immunophenotyping data and the current experimental evidence concerning IFN-R expression, constitutive JAK-STAT activation, and ISG overexpression in DS. Despite the lack of direct evidence that implicating this mild interferonopathy directly in illnesses in individuals with DS, we highlight the challenges ahead and directions that could be taken to determine more clearly the biological impact of interferonopathy on various immune-related conditions in DS.

Abstract
BACKGROUND Autoimmune thyroid disease and thyroid dysfunction are common in adults receiving interferon (IFN)-based treatment for chronic hepatitis C (CHC). Few data are available in children with CHC. This study is aimed to evaluate the appearance and timing of thyroid dysfunction and antithyroid autoimmunity in children with CHC treated with pegylated IFN-α-2b and ribavirin (RBV). METHODS Sixty-one otherwise healthy children with CHC, 3-17 years of age, infected perinatally and treatment naïve, receiving therapy with pegylated IFN-α-2b and RBV and 183 age- and sex-matched controls were included in a multicenter, prospective, case-control study. Thyroid-stimulating hormone, free thyroxine, antithyroglobulin antibodies and antithyroid peroxidase antibodies were assessed before, during and 24 weeks after the end of treatment. RESULTS From baseline to the end of treatment, subclinical hypothyroidism and autoimmune thyroiditis were diagnosed in 17 of 61 (27.94%) and in 4 of 61 (6.6%) of the children treated, respectively, and in 5 of 183 (2.7%) and in none of the controls (P < 0.0001, relative risk: 10.2, 95% confidence interval: 3.9-26.5; P = 0.03, relative risk: 26.8, 95% confidence interval: 1.5-489.1, respectively). Twenty-four weeks after the end of treatment, subclinical hypothyroidism persisted in only 4 of 61 (6.6%). Autoimmune thyroiditis persisted in 3 of 4 (75%) of the cases. CONCLUSIONS Subclinical hypothyroidism is common in children with CHC receiving treatment with pegylated IFN-α-2b and RBV, but in most cases is transient. Autoimmune thyroiditis, which is less common, generally persists after treatment completion. Thyroid function should be carefully monitored in patients presenting with antithyroid autoantibodies and thyroid dysfunction during and after pegylated IFN-α-based treatment.

Abstract
Background/purpose One to three per cent of the world’s population has hepatitis C virus (HCV) infection, which is not only a major cause of liver disease and cancer but also associated with an increased risk of atherosclerosis, despite an ostensibly favourable lipid profile. Autoantibodies are frequent in HCV infection and emerging evidence shows that autoantibodies could be valuable for cardiovascular disease (CVD) risk stratification. This study investigated a novel independent biomarker of CVD, autoantibodies to apolipoprotein A-1 (anti-apoA-1 IgG) and lipids in patients with chronic HCV before, during and after direct-acting anti-viral (DAA) therapy. Methods Eighty-nine blinded serum samples from 27 patients with advanced chronic HCV were assayed for lipids and anti-apoA-1 IgG by ELISA. Results Pre-treatment HCV viral load correlated with high-density lipoprotein cholesterol (HDL-C, r = 0.417; p = 0.042) and negatively with apolipoprotein (apo)B (r = − 0.497; p = 0.013) and markers of CVD risk, the apoB/apoA-1 ratio (r = − 0.490; p = 0.015) and triglyceride level (TG)/HDL-C ratio (r = − 0.450; p = 0.031). Fourteen (52%) of 27 patients had detectable anti-apoA-1 IgG autoantibodies pre-treatment; only two became undetectable with virological cure. Autoantibody-positive sera had lower apoA-1 (p = 0.012), HDL-C (p = 0.009) and total cholesterol (p = 0.006) levels. Conclusions This is the first report of the presence of an emerging biomarker for atherosclerosis, anti-apoA-1 IgG, in some patients with HCV infection. It may be induced by apoA-1 on the surface of HCV lipoviral particles. The autoantibodies inversely correlate with apoA-1 and HDL levels and may render HDL dysfunctional. Whether these hypothesis-generating findings have clinical implications in HCV patients requires further study.

Abstract
OBJECTIVES The purpose of the present study is to estimate autoantibody (auto-AB) frequency, clinical characteristics, and 21-day outcome of participants in the Pediatric Acute Liver Failure Study Group (PALFSG) by antinuclear antibody, smooth muscle antibody, and liver-kidney microsomal (LKM) antibody status. METHODS Auto-ABs were determined at local and/or central laboratories. Subjects were assigned to autoimmune hepatitis (AIH), indeterminate, and other diagnoses groups. RESULTS Between 1999 and 2010, 986 subjects were enrolled in the PALFSG. At least 1 auto-AB result was available for 722 (73.2%). At least 1 auto-AB was positive for 202 (28.0%). Diagnoses for auto-AB+ subjects were AIH (63), indeterminate (75), and other (64). Auto-ABs were more common in Wilson disease (12/32, 37.5%) compared with other known diagnoses (52/253, 20.6%, P = 0.03). LKM+ subjects were younger (median 2.4 vs 9.1 years, P < 0.001) and more likely to undergo liver transplantation (53.3% vs 31.4% P = 0.02) than other auto-AB+/LKM- subjects. Steroid treatment of subjects who were auto-AB+ was not significantly associated with survival and the subgroup with known diagnoses other than AIH had a higher risk of death. CONCLUSIONS Auto-ABs are common in children with acute liver failure, occurring in 28%. Auto-AB+ subjects have similar outcomes to auto-AB negative subjects. LKM+ children are younger and more likely to undergo liver transplantation compared with other auto-AB+ subjects. Although auto-AB may indicate a treatable condition, positivity does not eliminate the need for a complete diagnostic evaluation because auto-ABs are present in other conditions. The significance of auto-AB in pediatric acute liver failure remains uncertain, but LKM+ appears to identify a unique population of children who merit further study.

Abstract
OBJECTIVE To elucidate the association between antiviral therapy and extrahepatic outcomes in individuals infected with HCV. METHODS This nationwide cohort study screened 293,480 Taiwanese residents with HCV infection and excluded those with substantial comorbidity. A total of 12,384 eligible patients who had received pegylated interferon plus ribavirin between 1 October 2003 and 31 December 2010 were enrolled in the treated cohort; they were matched 1 : 2 with 24,768 untreated controls in the propensity score and post-diagnosis treatment-free period. The incidences of end-stage renal disease (ESRD), acute coronary syndrome (ACS), ischaemic stroke and catastrophic autoimmune diseases were calculated after adjustment for competing mortality. RESULTS The treated and untreated cohorts were followed up for a mean (±SD) duration of 3.3 (±2.5) and 3.2 (±2.4) years, respectively, until 31 December 2011. The calculated 8-year cumulative incidences of ESRD, ACS, ischaemic stroke and autoimmune catastrophes between treated and untreated patients were 0.15% vs. 1.32% (p<0.001), 2.21% vs. 2.96% (p=0.027), 1.31% vs. 1.76% (p=0.001) and 0.57% vs. 0.49% (p=0.816), respectively. Multivariate-adjusted Cox regression revealed that antiviral treatment was associated with lower risks of ESRD (HR 0.15; 95% CI 0.07 to 0.31; p<0.001), ACS (HR 0.77; 95% CI 0.62 to 0.97; p=0.026) and ischaemic stroke (HR 0.62; 95% CI 0.46 to 0.83; p=0.001), but unrelated to autoimmune catastrophes. These favourable associations were invalid in incompletely treated patients with duration <16 weeks. CONCLUSIONS Antiviral treatment for HCV is associated with improved renal and circulatory outcomes, but unrelated to catastrophic autoimmune diseases.

Abstract
BACKGROUND Triple therapy with pegylated interferon, ribavirin and a protease inhibitor has proven efficacy in hepatitis C infection and is currently the standard of care. Interferon-based therapies have been, rarely, associated with the development of Type 1 diabetes mellitus, but few cases have yet been reported in triple therapy for hepatitis C. CASE REPORT We describe a case of autoimmune Type 1 diabetes developing in a 23-year-old woman after initiation of triple therapy for chronic hepatitis C virus infection. The patient had the IL-28B gene polymorphism rs12979860 CT genotype, which is associated not only with antiviral therapy response but also with diabetes risk after liver transplantation for hepatitis C. CONCLUSION Further studies are required to determine which individual characteristics may identify patients who are at risk of developing Type 1 diabetes when treated with interferon-based regimens for hepatitis C infection.

Abstract
Diabetes and hepatitis C infection are both prevalent diseases worldwide, and are associated with increased morbidity and mortality. Most studies, but not all, have shown that patients with chronic hepatitis C are more prone to develop type 2 diabetes (T2D) compared to healthy controls, as well as when compared to patients with other liver diseases, including hepatitis B. Furthermore, epidemiological studies have revealed that patients with T2D may also be at higher risk for worse outcomes of their hepatitis C infection, including reduced rate of sustained virological response, progression to fibrosis and cirrhosis, and higher risk for development of hepatocellular carcinoma. Moreover, hepatitis C infection and mainly its treatment, interferon α, can trigger the development of type 1 diabetes. In this review, we discuss the existing data on this two-way association between diabetes and hepatitis C infection with emphasis on possible mechanisms. It remains to be determined whether the new curative therapies for chronic hepatitis C will improve outcomes in diabetic hepatitis C patients, and conversely whether treatment with Metformin will reduce complications from hepatitis C virus infection. We propose an algorithm for diabetes screening and follow-up in hepatitis C patients.

Abstract
Background Associations between breast cancer and thyroid disorders are reported in numerous studies. Relationships between thyroperoxidase antibodies (TPOAb), thyroglobulin antibodies (TgAb) and breast cancer have been previously demonstrated. However, no analysis has been performed concerning an association between thyrotropin (TSH) receptor antibodies (TSHRAb) and breast cancer. The aim of the study was to evaluate the prevalence of breast cancer or benign breast tumors in patients with Graves’ disease and to analyze a possible relationship between Graves’ disease and these two groups of breast diseases with emphasis to epidemiology and laboratory findings. Patients and methods Clinical and laboratory details of 2003 women hospitalized for endocrine disorders were retrospectively analyzed, using an unpaired Student’s t-test, logistic regression analysis, χ2 test of independence or the two-sided ratio comparison test. Results The coexistence of Graves’ disease and breast cancer was statistically significant. We observed TSHRAb and TgAb more frequently in patients with breast cancer. We found that TSHRAb is the only variable possessing predictive value for breast cancer. Conclusions The strong relationship between Graves’ disease and breast cancer is proposed. We suggest that TSHRAb could be described as a positive determinant of breast cancer. The present data call attention to the usefulness of screening for breast cancer in long-term follow-up of patients with autoimmune thyroid disorders, especially of those with Graves’ disease. Similarly, screening for autoimmune thyroid disorders should be performed in patients with nodular breast disease. Additionally, the article draws ideas for further research in order to develop targeted treatment for more successful outcome in patients with breast cancer.
