Summary
People with HIV have higher cancer risks, especially with lower CD4 counts. Oncoviruses like HHV-8, HPV, and EBV are linked to increased malignancies in HIV carriers.
Area of Science:
- Oncology
- Virology
- Immunology
Background:
- Individuals with Human Immunodeficiency Virus (HIV) exhibit a higher prevalence of neoplasms compared to HIV-negative populations.
- The risk of malignancies associated with oncoviruses escalates with diminished CD4+ T-cell counts in individuals living with HIV.
Discussion:
- Kaposi sarcoma, Castleman disease, and primary effusion lymphomas are frequently observed in HIV carriers due to Human Herpesvirus 8 (HHV-8) infection.
- Cancers of the anus and cervix are notably linked to Human Papillomavirus (HPV) in the context of HIV.
- Epstein-Barr virus (EBV) is implicated in the pathogenesis of Burkitt lymphoma and large B-cell lymphoma among individuals with HIV.
Key Insights:
- Oncovirus-associated cancers represent a significant clinical challenge in HIV management.
- CD4 count serves as a critical indicator for the risk of developing these specific malignancies.
- Early detection and management of oncoviral infections are crucial for mitigating cancer risk in HIV-positive individuals.
Outlook:
- Further research into targeted therapies against oncoviruses in HIV-positive individuals is warranted.
- Strategies for enhancing immune reconstitution in HIV patients may reduce the incidence of these cancers.
- Long-term surveillance and screening protocols are essential for managing oncovirus-related neoplasms in this population.

01:51Mechanisms of Retrovirus-induced Cancers
7.2K
Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...

6.6K
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

01:10Retrovirus Life Cycles
50.6K
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...
