Participation of Interferon-Alpha in Regulation of Apoptosis

Novel therapeutic drug strategies to tackle immune-oncological challenges faced by cancer patients during COVID-19

INTRODUCTION

For the clinical treatment of cancer patients, coronavirus (SARS-CoV-2) can cause serious immune-related problems. Cancer patients, who experience immunosuppression due to the pathogenesis and severity of disease, may become more aggressive due to multiple factors such as age, comorbidities, and immunosuppression. In this pandemic era, COVID-19 causes lymphopenia, cancer cell awakening, inflammatory diseases, and a cytokine storm that worsens disease-related morbidity and prognosis.

AREAS COVERED

We discuss all the risk factors of COVID-19 associated with cancer patients and propose new strategies to use antiviral and anticancer drugs for therapeutic purposes. We bring new drugs, cancers and COVID-19 treatment strategies together to address the immune system challenges faced by oncologists.

EXPERT OPINION

The chronic inflammatory microenvironment caused by COVID-19 awakens dormant cancer cells through inflammation and autoimmune activation. Drug-related strategies to ensure that clinical treatment can reduce the susceptibility of cancer patients to COVID-19, and possible counter-measures to minimize the harm caused by the COVID-19 have been outlined. The response to the pandemic and recovery has been elaborated, which can provide information for long-term cancer treatment and speed up the optimization process.

Hemangioendothelioma of the Bladder: The Youngest Case Report in A Child

Hemangioendothelioma is a vascular tumor that commonly found in soft tissue, lungs, heart, liver, and bones, but it is very rare in bladder. We report a case of pediatric hemangioendothelioma of the bladder in a 2 years 7 months-old boy that treated with total excision of the bladder and bilateral ureterocutaneoustomy. This case is the second case in pediatric patients, and the youngest case that reported in a child. Our patient is doing well post operatively. But unfortunately interferon a-2b is not available in our hospital. At 3 months follow up, there was progressive progression of the tumor. Recurrent Abdominal mass was confirmed by Abdominal CT-Scan. The patient was died one week later. Interferon a-2b is might be an effective regimen on this tumor but further study is needed to confirm this statement.

Human interferon alpha-2b: a therapeutic protein for cancer treatment

Human interferon alpha (hIFNα) is a wide biological activity cytokine that is used in hepatitis and cancer treatments. It regulates many genes that are involved in antiviral and antiproliferative activities. This mini review focuses on human interferon alpha-2b (hIFNα-2b) as therapeutic protein for cancer treatment. The review covers hIFNα-2b molecular characteristic and its molecular mechanism by Janus activated kinase/signal transducer activation of transcription (JAK-STAT) pathway. The JAK-STAT pathway regulates not only proteins involved in inhibition of proliferation but also apoptosis. As additional discussion of clinical applications, the use of recombinant hIFNα-2b (rhIFNα-2b) as therapeutic protein in several types of cancer is also explained.

Clinical utility of serum interleukin-8 and interferon-alpha in thyroid diseases

Serum interleukin-8 (IL-8) and interferon-alpha (IFN-α) levels have been estimated from a total of 88 individuals of which 19 were disease-free healthy individuals, and 69 were patients with thyroid diseases: goitre (N = 21), autoimmune diseases (N = 16), and carcinomas (N = 32). Both IL-8 and IFN-α were significantly higher in all the patients as compared to healthy individuals. Serum IL-8 levels showed significant positive correlation with disease stage in thyroid cancer patients. Higher serum IL-8 levels were associated with advanced disease stage while no significant correlation was observed between serum IFN-α levels and any of the clinicopathological parameters. IL-8 and IFN-α significantly correlated with each other in anaplastic carcinoma patients. Finally concluding, monitoring the serum IL-8 and IFN-α levels can help differentiate patients with thyroid diseases from healthy individuals, and IL-8 seems to have a role in the pathogenesis of thyroid diseases and may represent a target for innovative diagnostic and therapeutic strategies.
