Update on peanut allergy: Prevention and immunotherapy.
Allergy and Asthma Proceedings
|December 25, 2018
Summary
Advances in food immunotherapy, including oral, sublingual, and epicutaneous immunotherapy (OIT, SLIT, EPIT), show promise for treating food allergies, particularly peanut allergy. Recent studies indicate potential for sustained unresponsiveness, with ongoing trials advancing the field.
Area of Science:
- Immunology
- Allergy Research
- Pediatric Allergy
Background:
- Rising prevalence and significant burden of food allergies.
- Current food allergy treatments remain largely experimental.
- Need for effective prevention and treatment strategies.
Purpose of the Study:
- Review recent advances (past 18 months) in food allergy prevention and treatment.
- Focus on peanut allergy interventions.
- Evaluate immunotherapy approaches and guideline updates.
Main Methods:
- Literature review of recently published trials.
- Analysis of oral immunotherapy (OIT), sublingual immunotherapy (SLIT), and epicutaneous immunotherapy (EPIT) studies.
- Examination of updates to early peanut introduction guidelines.
Main Results:
- Addendum guidelines enhance early peanut introduction implementation.
- OIT demonstrates efficacy, with sustained unresponsiveness (SU) in up to 50% post-treatment, higher in toddlers.
- SLIT shows desensitization potential with longer durations; EPIT maintains safety and efficacy in children.
- Protocol adjustments improve OIT practicality and safety.
Conclusions:
- Significant progress in food immunotherapy (OIT, SLIT, EPIT) regarding safety and efficacy.
- Understanding of immunotherapy mechanisms continues to evolve.
- While experimental, ongoing phase III studies suggest future clinical applications.

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.

02:59Cancer Prevention
8.1K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

01:14Prevention of Further Absorption of Poison
1.3K
In cases of acute poisoning, the primary objective is to prevent further absorption of the toxic substance into the body. Immediate interventions using various decontamination techniques targeting the gastrointestinal (GI) tract can achieve this. Decontamination is crucial to prevent poison from entering the systemic circulation, which involves washing affected areas with water and mild soap and removing contaminated clothing. Once external decontamination is done, attention must be turned to...

Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

Nursing management of pneumonia involves promoting airway patency, facilitating rest and conserving energy, encouraging fluid intake, maintaining nutrition, and educating patients.
The nurse must practice strict medical asepsis and adhere to infection control guidelines to minimize healthcare-associated infections.
Enhance airway patency
Position the patient correctly to facilitate drainage of the affected lung segments. Manual or mechanical percussion and vibration can also be employed....

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
