Dermatomyositis associated with hepatitis B virus-related hepatocellular carcinoma

Paraneoplastic Cutaneous Manifestations of Hepatocellular Carcinoma. A Systematic Review and Meta-analysis

Background: There remains a scarcity of published data on the clinical significance of paraneoplastic cutaneous manifestations in hepatocellular carcinoma (HCC). Method: A systematic search of MEDLINE was performed in December 2022. Inclusion criteria comprised studies reporting on patients with HCC, who had paraneoplastic cutaneous manifestations. Outcomes of interests comprise survival and response to cancer-directed and/or skin directed therapy. Results: A total of 48 studies comprising 60 HCC patients were included in the analysis. The most frequent reported skin abnormalities were dermatomyositis, pityriasis rotunda, and porphyria. Most patients presented with dermatomyositis had underlying viral hepatitis, while all reported porphyria and acanthosis cases were associated with metabolic causes of HCC, such as steatosis. Paraneoplastic skin changes were more common in patients with metastatic disease. Pityriasis Rotunda was associated with the lowest risk of death, (OR: 0.05, 95% CI: 0.003 to 0.89; p = 0.04), while dermatomyositis had a statistically significant higher risk of death (OR: 3.37, 95% CI: 1.01-12.1; p = 0.03). Most patients showed an improvement in their cutaneous abnormalities, following cancer-directed therapy. Conclusion: Paraneoplastic cutaneous manifestations are reported more frequently in patients with a higher burden of disease, especially presence of metastases. Certain cutaneous manifestations have prognostic implication.

Risk prediction for dermatomyositis-associated hepatocellular carcinoma

OBJECTIVE

To explore dermatomyositis signature genes as potential biomarkers of hepatocellular carcinoma and their associated molecular regulatory mechanisms.

METHODS

Based on the mRNA-Seq data of dermatomyositis and hepatocellular carcinoma in public databases, five dermatomyositis signature genes were screened by LASSO regression analysis and support vector machine (SVM) algorithm, and their biological functions in dermatomyositis with hepatocellular carcinoma were investigated, and a nomogram risk prediction model for hepatocellular carcinoma was constructed and its predictive efficiency was initially evaluated. The immune profile in hepatocellular carcinoma was examined based on the CIBERSORT and ssGSEA algorithms, and the correlation between five dermatomyositis signature genes and tumor immune cell infiltration and immune checkpoints in hepatocellular carcinoma was investigated.

RESULTS

The expression levels of five dermatomyositis signature genes were significantly altered in hepatocellular carcinoma and showed good diagnostic efficacy for hepatocellular carcinoma, suggesting that they may be potential predictive targets for hepatocellular carcinoma, and the risk prediction model based on five dermatomyositis signature genes showed good risk prediction efficacy for hepatocellular carcinoma and has good potential for clinical application. In addition, we also found that the upregulation of SPP1 expression may activate the PI3K/ART signaling pathway through integrin-mediated activation, which in turn regulates the development and progression of hepatocellular carcinoma.

CONCLUSION

LY6E, IFITM1, GADD45A, MT1M, and SPP1 are potential predictive targets for new-onset hepatocellular carcinoma in patients with dermatomyositis, and the upregulation of SPP1 expression may activate the PI3K/ART signaling pathway through the mediation of integrins to promote the development and progression of hepatocellular carcinoma.

Paraneoplastic Anti-Tif1-gamma Autoantibody-positive Dermatomyositis as Clinical Presentation of Hepatocellular Carcinoma Recurrence

Hepatocellular carcinoma (HCC) is rarely associated with autoimmune paraneoplastic syndromes. We report a case of anti-transcriptional intermediary factor-1 gamma (TIF1-γ)-positive dermatomyositis (DM) as clinical presentation of HCC recurrence in a 72-year-old male patient admitted to our hospital due to fatigue, myalgia, and typical skin rash. His medical history was notable for hepatitis C-related cirrhosis, successful treatment with direct-acting antiviral agents, and previously efficacious treatment of HCC. Laboratory testing showed significant rhabdomyolysis with anti-TIF1-γ antibodies at high titer, and DM was diagnosed. After a careful diagnostic workup, HCC recurrence was diagnosed. After first-line corticosteroid treatment, azathioprine and intravenous immunoglobulin treatments were administered; unfortunately, he mounted only partial response. Owing to the compromised performance status, no HCC treatment was feasible, and, according to international guidelines, he received only best supportive care. Here, we discuss the diagnostic, prognostic, and pathogenic roles of anti-TIF1-γ antibodies associated with paraneoplastic DM and the scant literature data on its occurrence in HCC patients. Considering the TIF1 gene family's established role in oncogenesis, we also review the role of TIF1-γ as a tumor-related neoantigen, leading to the development of clinically overt anti-TIF1-γ antibodies-positive DM.

Paraneoplastic syndromes in hepatocellular carcinoma: a review

INTRODUCTION

Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide, and a significant proportion (20-40%) of patients with HCC develop paraneoplastic syndromes (PNS). Despite this, there is a paucity of clinical evidence regarding PNS in HCC.

AREAS COVERED

A systematic search was performed to identify relevant case studies regarding PNS in HCC. Another search was conducted to identify studies that evaluated the impact of PNS on survival outcomes in HCC. Since there are currently no international guidelines for PNS in HCC, this review aims to provide comprehensive summaries and recommendations of PNS in HCC, including the pathophysiology, clinical features, diagnostic approach, and management, so that clinicians remain guided in caring for HCC patients with PNS. In general, PNS are associated with poorer survival outcomes and negative prognostic markers of HCC.

EXPERT OPINION

The presence of PNS has a significant influence on survival rates and clinical outcomes of patients with HCC. They contribute to significant morbidity, influencing patients' quality of life and fitness for curative and palliative therapies. Therefore, it is paramount for PNS to be integrated into routine investigations after diagnosing HCC to guide further management and prognostication of the disease.

Elevation in creatine kinase isoenzyme-MM associated with hepatocellular carcinoma: a case report and review of literature

We report the case of a 79-year-old woman with hepatocellular carcinoma (HCC) who presented with creatine kinase (CK)-MM elevation. On admission, her serum CK-MM level exceeded 4000 IU/L (normal, 44-206 IU/L), and computed tomography revealed two HCCs in hepatic segment VIII (23 mm, 86 mm). The patient denied experiencing muscular symptoms such as weakness or pain. Hypothyroidism, ischemic heart disease, muscular dystrophy, autoimmune myopathy, drug-induced rhabdomyolysis, and paraneoplastic inflammatory myositis syndrome (PIMS) were included in the differential diagnosis for high CK-MM, but none were suspected. Although the cause of elevated CK-MM was not elucidated, an HCC-related mechanism was considered and the tumor was resected. The CK-MM levels declined gradually to 300 IU/L postoperatively without any special perioperative management. Nineteen cases of HCC-associated CK-MM elevation have been reported in English thus far, in all of which, inflammatory myositis was concluded as the cause of CK-MM elevation. However, in this case, the elevation of CK-MM was associated with HCC-related mechanisms distinct from PIMS, suggesting HCC-related mechanisms should not be excluded as a cause of high CK-MM, even though PIMS is negative.

Autoimmunity and cancer

In many autoimmune rheumatic diseases, there is an increased risk of cancer compared to the general population. The link between autoimmunity and cancer is dynamic and bidirectional. Recent advances in terms of knowledge of biology, epidemiology, and long-term outcomes for the autoimmune rheumatic diseases have revealed several new connections between these two entities. Data suggest that chronic inflammation from the rheumatic diseases or their therapies may contribute to the onset and promotion of cancer. Conversely, antitumor immune responses may become cross-reactive with self-tissues resulting in the development of autoimmunity. In this review, we discuss about the potential mechanisms that link autoimmune rheumatic diseases and cancer and the association of malignancies with common autoimmune disorders. The increased incidence of malignancy in autoimmune rheumatic diseases has been largely described, although the biology underpinning this relationship should be further investigated. The development of evidence-based cancer screening recommendations in patients with autoimmune rheumatic diseases is complex due to the heterogeneity of clinical rheumatic phenotypes, cancer sites at risk and exposure to anti-neoplastic and anti-rheumatic treatment. In order to lay the foundation of risk stratification and targeted cancer screening, larger longitudinal cohort studies that provide a more detailed framework of the links between cancer and autoimmunity are urgently needed.

Environmental triggers of dermatomyositis: a narrative review

Dermatomyositis (DM) is an autoimmune disease that affects the skin, lungs, and muscle. Although the pathogenesis of DM is not completely understood, several environmental triggers have been linked to DM onset or flare. This article specifically examines the effects of herbal supplements, drugs, infections, ultraviolet (UV) radiation, and environmental pollutants on the onset or exacerbation of DM. Herbal supplements such as Spirulina platensis, Aphanizomenon flos-aquae, Chlorella, Echinacea, and Alfalfa have been implicated and are frequently used in health foods. Medications such as hydroxyurea, TNF-α inhibitors, immune checkpoint inhibitors (ICI), and penicillamine, as well as certain viral infections, such as parvovirus B19, coxsackie virus, polyomavirus, Epstein-Barr virus (EBV), hepatitis, influenza, and human immunodeficiency viruses (HIV) have been associated with DM onset. Bacterial infections and vaccinations have also been linked to the development of DM. Additional environmental factors, including UV radiation and air pollutants, such as silica, biological/mineral dust, and particulate air matter from vehicle and industrial emissions, may also play a role in DM pathogenesis. Overall, there is general agreement that an autoimmune attack of the skin, muscle, and lungs in DM can be triggered by various environmental factors and warrants further investigation.

Value of 18F-FDG PET/CT in the detection of occult malignancy in patients with dermatomyositis

Aim

Dermatomyositis (DM) is an inflammatory myopathy in adults that is strongly associated with malignancy. The aim of this study was to evaluate whether whole-body ¹⁸F-FDG PET/CT imaging can offer a standard option searching for underlying malignancy in DM patients.

Methods

Seventy-five patients diagnosed with DM were referred to our department for whole-body ¹⁸F-FDG PET/CT to determine whether the patients suffered from malignant tumor. All PET images were analyzed by two experienced nuclear medicine physicians separately.

Results

According to the ¹⁸F-FDG PET/CT results, 19 patients were suspected to suffer from malignant tumor, then biopsy was performed. Of the 19 patients, 17 patients were confirmed to have malignant tumor. The pathological types were: nasopharyngeal carcinoma, rectal cancer, lung cancer, colon cancer, gastric cancer, gallbladder cancer, kidney cancer, ovarian cancer, breast cancer, lymphoma and vertebral metastatic adenocarcinoma of unknown origin. No malignancy was found for the 56 PET-negative patients during follow-up. For the age between 17 patients with malignancy and 58 patients without malignancy, no significant difference was observed.

Conclusion

¹⁸F-FDG PET/CT may be a sensitive and effective method in determining whether the patients with DM suffered from malignant tumor.

Polymyositis and dermatomyositis - challenges in diagnosis and management

Polymyositis (PM) and dermatomyositis (DM) are different disease subtypes of idiopathic inflammatory myopathies (IIMs). The main clinical features of PM and DM include progressive symmetric, predominantly proximal muscle weakness. Laboratory findings include elevated creatine kinase (CK), autoantibodies in serum, and inflammatory infiltrates in muscle biopsy. Dermatomyositis can also involve a characteristic skin rash. Both polymyositis and dermatomyositis can present with extramuscular involvement. The causative factor is agnogenic activation of immune system, leading to immunologic attacks on muscle fibers and endomysial capillaries. The treatment of choice is immunosuppression. PM and DM can be distinguished from other IIMs and myopathies by thorough history, physical examinations and laboratory evaluation and adherence to specific and up-to-date diagnosis criteria and classification standards. Treatment is based on correct diagnosis of these conditions.

•

Challenges of diagnosis and management influences the clinical research and practice of Polymyositis and dermatomyositis.

•

Diagnostic criteria have been updated and novel therapies have been developed in PM/DM.

•

Pathogenesis investigation and diagnosis precision improvement may help to guide future treatment strategies.

Hepatitis B virus-related liver cirrhosis complicated with dermatomyositis: A case report

BACKGROUND

Twenty percent of patients infected with hepatitis B virus (HBV) develop extrahepatic manifestations with HBV detected in the lymph nodes, spleen, bone marrow, kidneys, and skin. HBV infection has been associated with some autoimmune disorders. Dermatomyositis (DM) is an idiopathic inflammatory myopathy, which involves a viral infection, and DM has been identified in patients infected with HBV, but there is no direct histological evidence for an association between HBV and DM.

CASE SUMMARY

We describe a familial HBV-infected patient admitted with liver function abnormality, rashes, a movement disorder, and an elevated level of creatine kinase (CK). A computed tomography scan of the lung showed pulmonary fibrosis, and a liver biopsy identified nodular cirrhosis. An electromyogram revealed myogenic damage, and a muscle biopsy showed nuclear migration in local sarcolemma and infiltration of chronic inflammatory cells. Immunohistochemical staining showed negative results for HBsAg and HBcAg. Fluorescence in situ hybridization showed a negative result for HBV DNA. The patient was diagnosed with HBV-related liver cirrhosis complicated with DM and was treated with methylprednisolone, mycophenolate mofetil, and lamivudine. Eight months later, the patient was readmitted for anorexia and fatigue. The blood examination showed elevated levels of aminotransferases and HBV DNA, however, the CK level was within the normal range. The patient developed a virological breakthrough and lamivudine was replaced with tenofovir.

CONCLUSION

DM in chronic HBV-infected patients does not always associate with HBV. Antiviral and immunosuppressive drugs should be taken into consideration.

Expression of the OAS Gene Family Is Highly Modulated in Subjects Affected by Juvenile Dermatomyositis, Resembling an Immune Response to a dsRNA Virus Infection

Background: Juvenile dermatomyositis (JDM) is a systemic, autoimmune, interferon (IFN)-mediated inflammatory muscle disorder that affects children younger than 18 years of age. JDM primarily affects the skin and the skeletal muscles. Interestingly, the role of viral infections has been hypothesized. Mammalian 2′-5′-oligoadenylate synthetase (OAS) genes have been thoroughly characterized as components of the IFN-induced antiviral system, and they are connected to several innate immune-activated diseases. The main purpose of the paper is to define the potential interrelationship between the OAS gene family network and the molecular events that characterize JDM along with double-stranded RNA (dsRNA) molecular pathways. Methods: We analyzed three microarray datasets obtained from the NCBI in order to verify the expression levels of the OAS gene family network in muscle biopsies (MBx) of JDM patients compared to healthy controls. Furthermore, From GSE51392, we decided to select significant gene expression profiles of primary nasal and bronchial epithelial cells isolated from healthy subjects and treated with polyinosinic-polycytidylic acid (poly(I:C)), a synthetic analog of double-stranded RNA (dsRNA), a molecular pattern associated with viral infection. Results: The analysis showed that all OAS genes were modulated in JDM muscle biopsies. Furthermore, 99% of OASs gene family networks were significantly upregulated. Of importance, 39.9% of modulated genes in JDM overlapped with those of primary epithelial cells treated with poly(I:C). Moreover, the microarray analysis showed that the double-stranded dsRNA virus gene network was highly expressed. In addition, we showed that the innate/adaptive immunity markers were significantly expressed in JDM muscles biopsies. and that their levels were positively correlated to OAS gene family expression. Conclusion: OAS gene expression is extremely modulated in JDM as well as in the dsRNA viral gene network. These data lead us to speculate on the potential involvement of a viral infection as a trigger moment for this systemic autoimmune disease. Further in vitro and translational studies are needed to verify this hypothesis in order to strategically plan treatment interventions.

Dermatomyositis as an extrahepatic manifestation of hepatitis B virus-related hepatocellular carcinoma: A case report and literature review

RATIONALE

Dermatomyositis is an idiopathic inflammatory myopathy with specific cutaneous manifestations, which is closely associated with malignancy. However, the exact mechanism remains elusive. Even less is known about dermatomyositis with hepatocellular carcinoma (HCC).

PATIENT CONCERNS

We reported a case of dermatomyositis with hepatitis B virus (HBV) infection. He incidentally found his lower limbs little weakness accompanied with his wrist erythema. He was found HBsAg positive for forty years with slightly positive of α-fetal protein (AFP).

DIAGNOSES

A dermapathology from his hand-wrist lesions demonstrated a scattered inflammatory infiltrate around the capillaries of the dermis. Abdominal enhanced computer tomography (CT) revealed infiltrative HCC affecting the whole liver, accompanied by liver metastasis and liver cirrhosis. Liver tumor needle biopsy pathology showed HCC with moderate differentiation. The left supraclavicular lymph node needle biopsy pathology confirmed metastasic HCC.

INTERVENTIONS

Prednisolone was gradually withdrawn with the introduction of Entecavir 0.5 mg daily. Radiofrequency ablation therapy for liver tumor was performed once in order to decrease the tumor load.

OUTCOMES

His muscle power improved to grade 4+/5 in the lower limb one month after anti-HBV treatment. However, this patient died finally from liver failure due to the development of liver tumor.

LESSONS

In the coming clinic work, we must pay more attention to the extrahepatic disorder induced by HBV. On treating experience, glucocorticoid administration is often contraindicated for HBV infected patients because of its potential promotion of HBV replication. Thus, it is necessary to administrate high-effective anti-HBV drug prior to glucocorticoid treatment in order to prevent liver failure.

Dermatomyositis Induced by Hepatitis B Virus-related Hepatocellular Carcinoma: A Case Report and Review of the Literature

Dermatomyositis or polymyositis as a paraneoplastic syndrome of hepatocellular carcinoma (HCC) is an uncommon event. Few cases have been reported in the literature. We herein report the case of a 55-year-old man with chronic hepatitis B and alcoholism who presented with skin rash. Abdominal computed tomography revealed multiple hypervascular liver tumors consistent with HCC. He subsequently developed dysphagia with proximal limb weakness. Laboratory tests and electromyography demonstrated inflammatory myopathy. We therefore diagnosed the patient with HCC-induced dermatomyositis. Prednisolone and anti-viral therapy were administered; however, the patient died two months later due to the progression of the disease. We review the cases of HCC-induced dermatomyositis and polymyositis in the literature.

Risk of Malignancy in Dermatomyositis and Polymyositis

BACKGROUND

There is variation in the risk of malignancy in dermatomyositis (DM) and polymyositis (PM) in the existing literature.

OBJECTIVE

To conduct a meta-analysis to estimate the risk of malignancy in DM and PM as compared with the general population.

METHODS

Medline and Embase Database abstracts were searched through August 2014 using the search terms myositis, neoplasms, and paraneoplastic syndromes. Population-based, observational studies in English were included. Meta-analyses were conducted using random-effects models.

RESULTS

A total of 5 studies with 4538 DM or PM patients were included in the analysis. The overall relative risk was 4.66 for DM and 1.75 for PM. By gender, the standardized incidence ratio (SIR) of malignancy among DM patients was 5.29 for males and 4.56 for females; the SIR of malignancy among PM patients was 1.62 for males and 2.02 for females. By time since diagnosis, the SIR of malignancy among DM patients was 17.29 in the first year, 2.7 between 1 and 5 years, and 1.37 after 5 years. By age group, the SIR among DM patients was 2.79 for patients between 15 and 44 years and 3.13 beyond 45 years.

CONCLUSIONS

Both DM and PM are associated with increased risk of malignancy, but the risk is higher in DM. The risk of malignancy is present in both genders and all age groups and is highest in the first year after diagnosis but persists beyond the fifth year in DM. Adults should be evaluated for malignancy at diagnosis, followed by long-term surveillance.
