Sexually Transmitted Infections

362
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

995
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...

Pulmonary Tuberculosis I

286
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.

Primary Lymphoid Organs01:16

Primary Lymphoid Organs

1.7K
Primary lymphoid organs are pivotal in the formation, development, and maturation of lymphocytes, the white blood cells that serve as the backbone of our immune system. This crucial function underscores their fundamental role in maintaining our overall health and immunity. The two primary lymphoid organs of prime importance are the red bone marrow and the thymus.
The red bone marrow is a soft, spongy tissue nestled in the interior of long bones such as the humerus and femur. It is the site...

Summary

Diffuse large B-cell lymphoma (DLBCL) in people with HIV (PWH) is a significant health concern. Combined antiretroviral therapy (cART) improves outcomes, necessitating collaboration between HIV specialists and oncologists for optimal treatment.

Area of Science:

  • Oncology
  • Infectious Diseases
  • Hematology

Background:

  • HIV-related lymphomas, particularly diffuse large B-cell lymphoma (DLBCL), remain a major cause of illness and death in people with HIV (PWH), despite advances in combined antiretroviral therapy (cART).
  • DLBCL is a complex disease with diverse morphological and molecular subtypes.
  • Historically, chemotherapy in PWH led to high toxicity and poor outcomes, especially before cART.

Purpose of the Study:

  • To review the current understanding of HIV-related DLBCL management.
  • To emphasize the role of cART in improving treatment outcomes for PWH with DLBCL.
  • To highlight the importance of interdisciplinary collaboration in managing treatment toxicities and drug interactions.

Main Methods:

  • Review of existing literature on HIV-related lymphomas and their treatment.
  • Analysis of the impact of cART on chemotherapy efficacy and toxicity in PWH.
  • Discussion of drug-drug interactions between antiretroviral and antineoplastic agents.

Main Results:

  • The introduction of cART has enabled the use of intensive chemotherapy regimens (e.g., R-CHOP, R-EPOCH) in PWH with DLBCL.
  • Evidence supports that cART improves survival rates in non-Hodgkin lymphoma (NHL) patients.
  • Modern cART regimens have a lower potential for drug interactions compared to older regimens.

Conclusions:

  • Combined antiretroviral therapy (cART) is crucial for improving survival in people with HIV (PWH) diagnosed with diffuse large B-cell lymphoma (DLBCL).
  • Optimal treatment requires careful management of potential drug interactions and overlapping toxicities between antiretroviral and chemotherapy drugs.
  • Close collaboration between HIV specialists and hemato-oncologists is essential for effective and safe management of PWH with NHL.
