Non--AIDS-defining malignancies in HIV
1David Geffen School of Medicine at the University of California Los Angeles, Los Angeles, CA, USA.
Summary
The incidence of non-AIDS-defining cancers (NADCs) is rising in HIV-infected individuals, leading to increased cancer mortality. These cancers often present earlier and have a worse prognosis in this population.
Area of Science:
- Oncology
- Infectious Diseases
- Immunology
Background:
- Antiretroviral therapy has reduced AIDS-defining cancers but increased non-AIDS-defining cancers (NADCs) in HIV-infected individuals.
- Increased longevity, immune activation, and direct HIV effects contribute to the rise in NADCs.
- NADCs in HIV patients exhibit earlier onset and poorer prognosis compared to the general population.
Purpose of the Study:
- To review the changing landscape of malignancies in human immunodeficiency virus (HIV) infection.
- To highlight the increasing incidence and mortality associated with non-AIDS-defining cancers (NADCs) in the context of effective antiretroviral therapy.
- To discuss the unique challenges and knowledge gaps in managing cancer in HIV-infected patients.
Main Methods:
- Review of current literature and clinical observations regarding cancer incidence in HIV-infected populations.
- Summary of a presentation by Ronald T. Mitsuyasu, MD, focusing on malignancies in HIV infection.
- Analysis of trends in AIDS-defining cancers versus non-AIDS-defining cancers (NADCs) during the antiretroviral therapy era.
Main Results:
- Incidence of AIDS-defining cancers has decreased, while NADCs have increased in HIV-infected patients.
- Mortality proportion associated with NADCs has risen in this population.
- Lung and skin cancers are among those with increased incidence, linked to factors like tobacco use and immune status.
Conclusions:
- HIV-infected individuals face a growing burden of NADCs with distinct clinical characteristics.
- Further research is crucial for understanding risk, prevention, and optimal treatment strategies for cancers in HIV patients.
- Managing malignancies in HIV requires addressing specific challenges related to immune status, longevity, and potential drug interactions.

01:26Sexually Transmitted Infections
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...
01:25Immunodeficiency Diseases
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.

01:27Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
01:10Retrovirus Life Cycles
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 retrovirus to...
01:51Mechanisms of Retrovirus-induced Cancers
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...
01:29Pulmonary Tuberculosis I
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
