Food allergy: Update on prevention and tolerance

The rate of food allergies in the United States keeps on rising, but nobody really knows the exact reasons why.  In this month’s issue of the Journal of Allergy and Clinical Immunology, Du Toit and colleagues review the literature and focus on the ‘dual allergen’ hypothesis (J Allergy Clin Immunol 2018; 141(1): 30-40).  Briefly, they explain that allergic sensitization may occur when there is low-level skin exposure to food allergens, while tolerance is more likely to develop in children to have early exposures to food proteins.  The data are mounting from both animal and human observational studies as well as randomized control studies.  The most notable has been the LEAP study, which showed that infants aged 4 to 11 months who consumed peanut products at least three times per week until age 60 months were far less likely to develop peanut allergies than infants who had complete avoidance.  Only 3.2% in the peanut-eating group developed peanut allergy, compared to 17.2% in the complete avoidance group.  The follow-up study, LEAP-On, demonstrated persistence of this tolerance for at least 12 months, even with strict avoidance in non-peanut allergic children.  Similarly, the EAT study suggested that lower rates of food allergies with early introduction of allergenic foods in breastfed infants, although conclusions were less clear-cut than in the LEAP study.  The results of other studies have been more variable.  Regardless, the LEAP and EAT studies show that early introduction of allergenic foods into infant diet is achievable and safe, and does not affect breastfeeding rates as well as later nutrition and growth.  However, there are a lot of challenges.  Ensuring adherence to dietary recommendations, determining the dosages of food proteins, and powering studies sufficiently to show meaningful differences are challenges that researchers and clinicians face.  This has led to the National Institutes of Health’s recommendation for early peanut introduction to prevent peanut allergy.  Other countries have also recommended inclusion of potential common food allergens in complementary feeding regimens at around 6 months.  With more research, it is possible that we may find more effective ways to help prevent food allergies.

  1. Irrespective of receiving daily oral or future injectable depot therapies, these require health care visits for medication and monitoring of safety and response. If patients are treated early enough, before a lot of immune system damage has occurred, life expectancy is close to normal, as long as they remain on successful treatment. However, when patients stop therapy, virus rebounds to high levels in most patients, sometimes associated with severe illness because i have gone through this and even an increased risk of death. The aim of “cure”is ongoing but i still do believe my government made millions of ARV drugs instead of finding a cure. for ongoing therapy and monitoring. ARV alone cannot cure HIV as among the cells that are infected are very long-living CD4 memory cells and possibly other cells that act as long-term reservoirs. HIV can hide in these cells without being detected by the body’s immune system. Therefore even when ART completely blocks subsequent rounds of infection of cells, reservoirs that have been infected before therapy initiation persist and from these reservoirs HIV rebounds if therapy is stopped. “Cure” could either mean an eradication cure, which means to completely rid the body of reservoir virus or a functional HIV cure, where HIV may remain in reservoir cells but rebound to high levels is prevented after therapy interruption.Dr Itua Herbal Medicine makes me believes there is a hope for people suffering from,Cancer,Hiv_ Aids,Herpes,Copd,Diabetes,Hepatitis,I read about him online how he cure Tasha and Tara so i contacted him on drituaherbalcenter@gmail.com even talked on whatsapps +2348149277967 believe me it was easy i drank his herbal medicine for two weeks and i was cured just like that isn't Dr Itua a wonder man?
