Summary
Individuals with human immunodeficiency virus (HIV) often have co-infections with hepatitis B (HBV) and hepatitis C (HCV). Managing these viral hepatitis co-infections is crucial for HIV patient health and treatment effectiveness.
Area of Science:
- Infectious Diseases
- Hepatology
- Public Health
Background:
- High-risk populations for human immunodeficiency virus (HIV) are frequently exposed to other bloodborne pathogens like hepatitis B virus (HBV) and hepatitis C virus (HCV).
- Transmission routes for HIV, HBV, and HCV often overlap, including injection drug use, sexual contact, and perinatal transmission.
- Liver disease is a significant cause of illness and death in individuals with HIV, especially with the advent of effective antiretroviral therapy (ART).
Purpose of the Study:
- To review current management strategies for HIV-infected individuals coinfected with HBV or HCV.
- To highlight the impact of viral hepatitis coinfection on ART efficacy and safety.
- To emphasize the importance of screening and appropriate management of HBV and HCV in HIV-positive patients.
Main Methods:
- Review of existing literature and expert guidelines on the management of HIV/HBV and HIV/HCV coinfections.
- Discussion of treatment options for HBV and HCV in the context of HIV infection.
- Analysis of challenges in ART delivery due to coinfection-related hepatotoxicity.
Main Results:
- Coinfection with HBV and/or HCV is prevalent in some populations and complicates HIV management.
- Viral hepatitis can increase the risk of drug-induced liver injury and influence ART regimen selection.
- Guidelines recommend screening all HIV-infected individuals for HBV and HCV.
Conclusions:
- Effective management of HBV and HCV coinfections is essential for improving outcomes in HIV-infected individuals.
- Treatment for HBV involves nucleos(t)ide analogues and/or peginterferon alfa (PegIFN).
- HCV treatment is primarily based on PegIFN and ribavirin (RBV).

Viral Hepatitis I: Introduction
Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
Hepatitis
Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...
Retrovirus 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...
Sexually 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...
Retroviruses
Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...
Inhibitors of Virion Maturation and Assembly
As part of their replication cycle, certain viruses synthesize long precursor proteins called polyproteins within infected host cells. In human immunodeficiency virus (HIV), two major polyproteins are produced: Gag and Gag-Pol. The Gag polyprotein supplies the structural components of the virus, while Gag-Pol includes essential viral enzymes such as reverse transcriptase, integrase, and protease. After synthesis, these polyproteins move to the host cell membrane, where they assemble into an...
