Tumor Immunotherapy01:27

Tumor Immunotherapy

2.6K
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Hypersensitivities01:30

Hypersensitivities

7.3K
Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

Drugs Used in Lower Respiratory Disorders: Overview

1.6K
Lower respiratory tract disorders present challenges that often require skilled and nuanced approaches for effective management. Common ailments, such as asthma and chronic obstructive pulmonary disease (COPD), have prompted the development of intricate treatment strategies involving bronchodilators and anti-inflammatory drugs, each tailored to ease breathing and revitalize the lungs.
Bronchodilators, the first step of respiration enhancement, come in various forms, each with its own mechanism...

Drug Toxicity: Allergic Reactions01:30

Drug Toxicity: Allergic Reactions

223
Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial...

Allergic Drug Reactions01:27

Allergic Drug Reactions

1.6K
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing...

Inflammatory Response01:28

Inflammatory Response

12.6K
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

Summary
This summary is machine-generated.

Recent studies suggest allergen immunotherapy (AIT) has declining fatal reactions. Strategies like patient screening and dose adjustments can reduce systemic reactions, with sublingual immunotherapy (SLIT) showing particularly low rates.

Area of Science:

  • Allergy and Immunology
  • Immunotherapy Research

Background:

  • Systemic reactions are a significant concern in allergen immunotherapy (AIT).
  • Accurate risk assessment and management strategies are crucial for patient safety during AIT.

Purpose of the Study:

  • To review and synthesize recent literature on reducing and managing systemic reactions to AIT.
  • To provide an updated perspective on the safety profiles of various AIT approaches.

Main Methods:

  • Systematic review of recent articles on allergen immunotherapy (AIT).
  • Analysis of studies focusing on systemic reaction rates and risk factors.
  • Evaluation of management and prevention strategies for AIT-related adverse events.

Main Results:

  • Fatal reactions to AIT appear to be decreasing.
  • Pre-AIT asthma screening and pollen season dose adjustments may lower systemic reaction rates.
  • Sublingual immunotherapy (SLIT) demonstrates consistently low systemic reaction rates, even with rapid protocols, while multiallergen subcutaneous immunotherapy (SCIT) may carry higher risks compared to single-allergen SCIT.

Conclusions:

  • Recent research enhances confidence in estimating systemic reaction risks associated with AIT.
  • Effective strategies for predicting and preventing systemic reactions to AIT are emerging.
  • The safety of AIT is improving with better patient selection and protocol adjustments.
