Retrovirus Life Cycles01:10

Retrovirus Life Cycles

48.8K
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

679
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...

Immunodeficiency Diseases

1.8K
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.
There are three main causes of immunodeficiency...

Area of Science:

  • Ophthalmology
  • Infectious Diseases
  • Immunology

Background:

  • Human Immunodeficiency Virus (HIV) infection leads to progressive immunodeficiency.
  • Depletion of CD4-positive T lymphocytes compromises the immune system.
  • Low CD4 counts (<200 cells/μl) increase susceptibility to opportunistic infections.

Purpose of the Study:

  • To review current knowledge on HIV-associated retinopathies.
  • To highlight key diagnostic and management considerations.

Main Methods:

  • Literature search of PubMed.
  • Keywords: "HIV Retinopathy OR Retinitis" and "HIV AND Retinitis".
  • Focus on manuscripts published within the last ten years.

Main Results:

  • Noninfectious HIV retinopathy presents as cotton wool spots.
  • Cytomegalovirus (CMV) retinitis is a significant opportunistic infection requiring differentiation from other causes.
  • Immune recovery uveitis can occur in CMV-affected eyes post-immune restoration.

Conclusions:

  • Prompt antiviral therapy is crucial for managing HIV retinopathy.
  • Secondary prophylaxis prevents recurrence and vision loss.
  • Management focuses on preventing vision loss prior to immune system recovery.
