About This Presentation

Description : Check out this medical PowerPoint presentation titled "Bee Venom Immunotherapy" by Dr Aarn Huissoon.

This medical PowerPoint presentation talks about Bee venom immunotherapy (BVIT). BVIT is a type of allergy treatment that involves administering increasing doses of bee venom to an allergic individual in order to desensitize them to the venom. The goal of BVIT is to reduce the severity of future allergic reactions to bee stings.

Slide 1-

Bee Venom Immunotherapy Dr Aarn Huissoon Consultant Immunologist Birmingham Heartlands Hospital
Slide 2-

I reacted to a sting – do I need VIT? Large Local reaction Swelling at the sting Develops over ~24 hours Settles over several days Antihistamines and steroids Not usually a reason for VIT Systemic reaction Symptoms in minutes May include any of: Itch, rash, flushing Swelling (e.g. skin, throat) Tight chest / wheeze / can’t breathe Dizzy, faint, collapse “Feeling of impending doom” Stomach cramps / diarrhoea Antihistamines and adrenaline YES - assessment for VIT
Slide 3-

What does VIT assessment involve? Detailed history of the reaction Timings, treatments, blood tests etc.. Allergy testing Skin prick test Intradermal test Blood test; bee venom IgE Breathing tests and ECG (some people) Blood test; Tryptase
Slide 4-

Immunotherapy Clinic Hospital-based Run by doctors / nurses Facilities for treating reactions Well on the day Pre-injection check Wait for 1 hour after injection Another check before home
Slide 5-

What happens in VIT? Build-up 12 weekly injections Increasing from 0.01 to 100 mg / injn Top-ups every 4-6 weeks for 3 yrs 100 mg is ~3 stings May be 5 yrs or more
Slide 6-

Risks of VIT Local or large local reactions in 50% Systemic reactions (SR) 2 to 20 % of patients have SR Risks for SRs: Female Bee allergy 14% (wasp 3%) Raised baseline tryptase
Slide 7-

Outcomes of VIT Protection 80% prevention of severe reactions Quality of life improved May also reduce large local reaction Boyle RJ Cochrane Database of Systematic Reviews 2012, Issue 10. Art. No.: CD008838

Slide 9-

How does VIT work? Type of immune response depends on how antigen is presented Dose Route (mouth, IV, ID SC…) Subcutaneous injections steer the immune response away from allergy
Slide 10-

VIT for Bee sting allergy You should be able to have VIT if: you have had a severe reaction to a bee sting or you have had a moderate reaction to a bee sting and you have a high risk of stings anxiety about stings high levels of a protein called ‘tryptase’ Adapted from: www.nice.org.uk/guidance/ta246
Slide 11-

Can anyone have VIT? Exclusions: Severe asthma Pregnancy Not able to consent / attend reliably Certain medications: b-blocker (e.g propranolol) ACE inhibitor (e.g. ramapril) Some antidepressants Some immune system disorders and cancers
