Background Cow’s milk protein allergy (CMPA) is one of the most common food allergies in infancy. Most infants with CMPA tolerate baked milk from diagnosis and gradually acquire increased tolerance. Nevertheless, parents often display significant anxiety about this condition and a corresponding reluctance to progress with home introduction of dairy due to concerns about possible allergic reactions. Objective: To evaluate the impact on gradual home introduction of foods containing cows milk after a supervised, single low dose exposure to whole milk at time of diagnosis. Methods Infants less than 12 months old, referred with suspected IgE-mediated cow’s milk allergy were recruited to an open-label randomised, controlled trial of intervention - a single dose of fresh cow’s milk, using the validated dose of milk that would elicit reactions in 5% of CMPA subjects - the ED 05 – vs routine care. Both groups implemented graded exposure to CM (using the 12 step MAP Milk Tolerance Induction Ladder), at Home. Parents completed food allergy quality of life and State and Trait Anxiety Inventories (STAI). Main outcome measures were milk ladder position at 6 months and 12 months post randomisation. Results: Sixty patients were recruited, 57 (95%) were followed to 6 months. By 6 months 27/37 (73%) intervention subjects had reached step 6 or above on the milk ladder compared to 10/20 (50%) control subjects (p=0.048). By 6 months 11/37 (30%) intervention subjects had reached step 12 (ie drinking unheated cow’s milk) compared to 2/20 (10%) of the controls (p=0.049). Twelve months post randomisation 31/36(86%) of the intervention group and 15/19(79%) of the control group were on step 6 or above. However, 24/37 (65%) of the intervention group were at step 12 compared to 7/20 (35%) of the control group (p=0.03). Maternal STAIs were significantly associated with their infants’ progress on the milk ladder and with changes in skin prick test and spIgE levels at 6 and 12 months. Conclusion This study demonstrates the safety and effectiveness of introduction of baked milk implemented immediately after diagnosis of cows milk allergy in a very young cohort. A supervised single dose of milk at the ED 05 significantly accelerates this further, probably by giving parents the confidence to proceed. Maternal anxiety generally reflects infants’ progress towards completion of the milk ladder, but pre-existing high levels of maternal anxiety are associated with poorer progress.

Background: Internationally, the COVID-19 pandemic severely curtailed access to hospital facilities for those awaiting elective/semi elective procedures. For allergic children in Ireland, already waiting up to 4yr for an elective oral food challenge (OFC), the restrictions signified indefinite delay. At the time of the initiative there were approx 900 children on the Chidren’s Health Ireland(CHI) waiting list. In July 2020, a project was facilitated by short term(6wk) access to an empty COVID stepdown facility built, in a hotel conference centre, commandeered by the Health Service Executive Ireland(HSE). The aim was to the achieve rapid rollout of an off-site OFC service, delivering high throughput of long waiting patients, while aligning with hospital existing policies and quality standards, international allergy guidelines and national social distancing standards. Methods: The working group engaged key stakeholders to rapidly develop an offsite OFC facility. Consultant Paediatric Allergists, Consultant Paediatricians, trainees and Allergy Clinical Nurse Specialists were seconded from other duties. The facility was already equipped with hospital beds, bedside monitors(BP, Pulse, Oxygen saturation) bedside oxygen. All medication and supplies had to be brought from the base hospital. Daily onsite consultant anaesthetic cover was resourced and a resuscitation room equipped. Standardised food challenge protocols were created. Access to onsite hotel chef facilitated food preparation. A risk register was established. Results: After 6wks planning, the remote centre became operational on 7/9/20, with the capacity of 27 OFC/day. 474 challenges were commenced, 465 (98%) were completed, 9(2%) were inconclusive. 135(29.03%) OFC were positive, 25(5%) causing anaphylaxis. No child required advanced airway intervention. 8 children were transferred to the base hospital. The CHI allergy waiting list was reduced by almost 60% in only 24 days. Conclusions: OFCs remain a vital tool in the care of allergic children, with their cost saving and quality of life benefits negatively affected by delay in their delivery. This project has shown it is possible to have huge impacts on a waiting list efficiently, effectively and safely with good planning and staff buy in – even in a pandemic. Adoption of new, flexible and efficient models of service delivery will be important for healthcare delivery in the post-COVID-19 era.
