ABSTRACT

Efficient protection against coronavirus disease 2019 (COVID-19) has been achieved by immunization with mRNA-based vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, efficient immune responses against this novel virus by vaccination are accompanied by a wide variety of side effects. Indeed, flares or new-onset of autoimmune disorders have been reported soon after the COVID-19 vaccination. Although pro-inflammatory cytokine responses play pathogenic roles in the development of autoimmunity, cytokines charactering COVID-19 vaccination-related autoimmune responses have been poorly understood. Given that mRNA derived from COVID-19 vaccine is a potent inducer for pro-inflammatory cytokine responses, these cytokines might mediate autoimmune responses after COVID-19 vaccination. Here we report a case with new-onset rheumatoid arthritis (RA) following COVID-19 vaccination. Serum concentrations not only of arthrogenic cytokines, interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α), but also of type I interferon (IFN) were elevated at the active phase in this case. Induction of remission by methotrexate and tocilizumab was accompanied by a marked reduction in serum concentrations of type I IFN, IL-6, and TNF-α. These results suggest that production of type I IFN, IL-6, and TNF-α induced by COVID-19 vaccination might be involved in this case with new-onset RA.

ABSTRACT

PURPOSE: The COVID-19 pandemic has altered healthcare priorities which may adversely impact cancer management. We aimed to evaluate the impact of the pandemic on the diagnosis, treatment, and consultation methods for patients with hepatocellular carcinoma (HCC). PATIENTS AND METHODS: We conducted a survey among 27 hospitals from 14 Asia-Pacific countries, collecting hospital-level information on the number of newly diagnosed HCC cases during a pre-pandemic period (February to May 2019) and for the same period during the pandemic (February to May 2020). Information was also collected on delays in diagnosis and treatment, changes in treatment modalities and complication rates, changes in patient enrollment in clinical trials, and modes of patient consultation. The information was stratified by the Barcelona Clinic Liver Cancer (BCLC) stage. RESULTS: The survey included cohorts of 2789 and 2045 patients newly diagnosed with HCC during the pre- and pandemic period, respectively. A decline of 26.7% in new HCC cases was reported during the pandemic compared to the pre-pandemic. A sizable proportion of institutions reported delays in diagnosis (48.2% in BCLC 0/A/B and 51.9% in BCLC C), delays in treatment (66.7% in BCLC 0/A/B and 63.0% in BCLC C), changes in treatment modality (33.3% in BCLC 0/A/B and 18.5% in BCLC C), an increase in treatment complications (about 15% across all BCLC stages), and no growth in clinical trial enrollments during the pandemic. Furthermore, there was a decline of 27.3% in face-to-face patient consultations and an increase of 18.3% in video/telephonic consultations during the pandemic. A considerable variation in changes in HCC management was observed among countries. CONCLUSION: The COVID-19 pandemic has significantly impacted the management of HCC among Asia-Pacific countries. The impact varies according to the disease stage and country. Well thought-through long-term strategies are required to ameliorate the negative impact of the pandemic on HCC patients.

ABSTRACT

Background: The pandemic of coronavirus disease 2019 (COVID-19) has diverted resources from healthcare services for patients with chronic medical illness such as cancer. COVID-19 also causes organ dysfunction, complicating cancer treatment. In most countries with an outbreak of COVID-19, modifications of cancer management have been adopted to accommodate the crisis and minimize the exposure of cancer patients to the infection. In countries where COVID-19 numbers are subsiding, medical teams should also be prepared to resume normal practices gradually. Here, we aim to review the literature on the impact of COVID-19 on patients with hepatocellular carcinoma (HCC) as well as discuss modifications to the management of HCC during and after recovery from the pandemic. Summary: Based on current data, 10–40% of patients with COVID-19 have hepatic injury characterized by an elevation of transaminases and/or hyperbilirubinemia. Multiple mechanisms contribute to the hepatic injury, including direct viral entry to hepatocytes/cholangiocytes, immune-mediated hepatitis, hypoxia, and drug-related hepatotoxicity. In patients with HCC, COVID-19 may exacerbate existing chronic liver disease and complicate the management of cancer. Cancer patients generally have a higher risk of infection and worse outcome, especially those who have recently undergone cancer treatment. Although HCC is under-represented in COVID-19 series, mitigation measures should be implemented to minimize the exposure of patients to the virus. A decision on the treatment of HCC should be balanced with consideration of the availability of medical resources, the level of infection risk of COVID-19, and the risk-benefit ratio of the individual patient. In areas where the COVID-19 outbreak is subsiding, clinicians should be prepared to manage a surge of HCC patients with higher disease burdens and complications. Key Messages: Mitigation measures to protect at-risk patients, such as those with cancers, from SARS-CoV-2 infection should be exercised and the impact of COVID-19 on this group of patients should be thoroughly studied.

ABSTRACT

This contingency guide was formulated on the premise that delivering standard treatment for hepatocellular carcinoma (HCC) has come under strain due to the coronavirus (COVID-19) pandemic. Measures required are likely to vary largely across regions and individual institutions, depending on the level of the strain imposed by the pandemic (e.g., number of inpatients infected with COVID-19 and the availability of resources, including personal protective equipment and inpatient beds). In addition, models suggest that the second and third waves of COVID-19 will occur before effective vaccines and medicines become widely available in Japan (expected time, 2-3 years). This guide should serve as a good reference for best practices in the management of HCC, which is in light of the possible risk of impending collapse of the healthcare system due to a surge in COVID-19 infections.
