Growth Patterns of Indonesian Infants with Cow's Milk Allergy and Fed with Soy-Based Infant Formula

Effect of oral food challenge on quality of life and family activities in children with IgE-mediated food allergies

BACKGROUND

Oral food challenge (OFC) is an integral part of confirming and evaluating the diagnosis of food allergy (FA), and most incidents of FA occur in children. FA significantly impairs the quality of life (QoL) and causes limited activities outside the home for children and their parents.

AIM

To evaluate the effect of OFC on QoL and family activities in children with FA.

METHODS

This prospective study identified children suspected of FA using a skin prick test (SPT) between January 2022 and December 2024. These children conduct an elimination diet for 4 wk, followed by OFC under protocol. Rating scales evaluated QoL using pediatric QoL inventory and family activities using family activities impact scale (FAIS), in which data are collected before and after an elimination diet and OFC. Statistical analysis utilized χ², Spearman , paired t, Wilcoxon, independent t, and Mann–Whitney tests, with P < 0.05 considered significant.

RESULTS

Most participants were boys (137; 65.55%); 102 (64.56%) had a positive OFC and 35 (68.63%) a negative OFC. The average QoL before OFC was 69.13 ± 5.78, and 92.40 ± 4.22 after OFC (Z = 12.537; P < 0.001). In the FAIS score, the average result before OFC was 5.36 ± 0.68 and 4.10 ± 0.38 after OFC, which was a significant difference (Z = 12.162; P < 0.001). Although the difference in QoL before and after increased, and FAIS reduced, there was no significant difference. Additionally, most results of positive SPT are higher than positive OFC in each specific food allergen.

CONCLUSION

OFC may improve QoL and FAIS in children with FA and their families as it increases activities outside the home and reduces worry about allergen exposure.

Difference in Cow's Milk-Related Symptom Score (CoMiSSTM) Among Presumed Healthy Infants in Indonesia and Brazil

Purpose

The Cow's Milk-related Symptom Score (CoMiSS) improves the recognition of cow milk allergy (CMA) symptoms. A score of ≥10 should raise awareness of CMA. The median CoMiSS in healthy European infants aged <6 months is 3. This study aimed to determine the impact of different regions on CoMiSS in healthy infants aged <12 months to evaluate regional and age-related differences.

Methods

A prospective cross-sectional study was conducted at one hospital each in Indonesia (Jakarta) and Brazil (Sergipe). CoMiSS was assessed in healthy infants aged -12 months old.

Results

In Jakarta, a total of 286 infants (50.7% boys) were included. The median (interquartile range) CoMiSS was 1.5 (0-4); the 95th percentile was 7. In Sergipe, 101 infants (60.4% boys) were included. The median (interquartile range) CoMiSS was 4 (4-6); the 95th centile was 10.9. Age (odds ratio [OR], 0.96; 95% confidence interval [CI], 0.94-0.99; p<0.001) and country (OR, 2.40; 95% CI, 2.06-2.79; p<0.001) were significant independent predictors of changes in mean CoMiSS in a linear regression model (r2=0.27).

Conclusion

Median CoMiSS in healthy infants differed between Jakarta and Sergipe (1.5 vs. 4.0). These findings highlight that the perceived normality of parents may be region-dependent.

Characteristic features of food allergy to legumes: From epidemiology to prevention

INTRODUCTION

The study aims to investigate the main characteristics of food allergies to legumes (peanuts, chickpeas, soybeans, lentils, beans, and peas).

MATERIALS AND METHODS

A search was conducted for relevant information in the ResearchGate, PubMed, Scopus, Google Scholar, and Web of Science databases, presented for 2011-2024.

RESULTS

The study determined that about 30 % of the world's population has allergic diseases. Of them, 10 % were diagnosed with food allergies. In Poland, the prevalence of this pathology is about 5 %. The epidemiology of food allergies to peanuts is 2-5 %. The prevalence of sensitisation to lentils is 5-7 %; to beans - 7.5 %; to soybeans - 9-10.4 %; to peas - 9.5 % and to chickpeas - 8.5 %. At the same time, no food allergies to soy have been detected in adults in Poland. Peanuts are the most allergenic food among those described in this study, as they have a high risk of sensitisation to nuts and legumes (soybeans, lupins, peas, chickpeas, lentils). The clinical picture of a legume allergy is characterised by hives, itching, sneezing, redness, lacrimation, nausea, vomiting, wheezing, angioedema, and anaphylactic shock. For the diagnosis of food allergy to legumes, an oral test, prick test, determination of the level of allergen-specific immunoglobulin E (IgE), and basophil activation test are used. Emergency care is provided using an epinephrine solution at a dosage of 1 mg/ml intramuscularly. Immunotherapy with allergens is used to treat delayed-type hypersensitivity reactions. To prevent legume allergy, physical, chemical, and biological methods of treatment and individual nutrition are used.

CONCLUSIONS

The study concluded that food allergy to legumes is a common pathology that contributes to the development of severe complications and requires detailed study.

Growth and Nutritional Biomarkers in Brazilian Infants with Cow's Milk Allergy at Diagnosis and 18-Month Follow-Up: A Prospective Cohort Study

Purpose

This study aimed to describe the growth, body protein status, and micronutrient biomarkers of Brazilian infants with cow's milk allergy (CMPA) at baseline and at 18 months of follow-up in comparison with their healthy peers.

Methods

Thirty infants with CMPA younger than six months of age were included in this longitudinal study, and their nutritional status was compared with that of 24 non-allergic age-matched children. Anthropometric measurements were used to assess growth, and blood and urine samples were analyzed for protein and micronutrient status. Mixed linear models adjusted for birth weight, socioeconomic status, infant feeding at baseline, weight-for-age, C-reactive protein, serum albumin, micronutrient dietary supplementation, and salt consumption were employed to evaluate the evolution of nutritional parameters throughout the follow-up period.

Results

Overall, the mean age of the children at enrolment was 2.9 (standard deviation 1.7) months, and 29 children (53.7%) were male. Infants with CMPA showed a higher prevalence of functional iron depletion (transferrin saturation <20) (p=0.027), lower serum ferritin (p=0.009), and lower urinary iodine (p=0.034) levels than non-allergic children at baseline. Patients with CMPA showed a higher increment in weight-for-age and length-for-age over time than those in the control group (p<0.01). Mixed linear analyses showed a significantly lower increase in serum vitamin B12 (s-B12) (p=0.001) and urinary iodine (p<0.001) concentrations over time compared to the control group.

Conclusion

Infants with CMPA on a cow's milk elimination diet had a higher weight and length at 18 months of follow-up but showed signs of inadequate iron, iodine, and B-12 vitamin status.

An Updated Review of Soy-Derived Beverages: Nutrition, Processing, and Bioactivity

The global market for plant-based drinks is experiencing rapid growth driven by consumer demand for more sustainable diets, including vegetarian and vegan options. Soy beverages in particular are gaining popularity among individuals with lactose intolerance and milk protein allergies. They are considered an excellent source of high-quality protein, vitamin B, unsaturated fatty acids, and beneficial phytochemicals such as phytosterols, soy lecithins, and isoflavones. This review presents a comprehensive market survey of fifty-two soy beverages available in Spain and other European countries. The predominant category among those evaluated was calcium and vitamin-fortified drinks, accounting for 60% of the market. This reflects the need to address the nutritional gap compared to cow's milk and meet essential dietary requirements. The review covers the technological aspects of industrial soy milk production, including both traditional methods and innovative processing techniques. Additionally, it analyzes multiple studies and meta-analyses, presenting compelling evidence for the positive effects of soy beverages on various aspects of health. The review specifically examines the contributions of different components found in soy beverages, such as isoflavones, proteins, fiber, and oligosaccharides. Moreover, it explores controversial aspects of soy consumption, including its potential implications for growth, puberty, fertility, feminization, and the thyroid gland.

Effects of regular soy formula intake between 1 and 2 months of age on food sensitization in infancy

BACKGROUND

The effects of regular soy formula (SF) intake on the development of food sensitization in infancy remain unclear. This study aimed to assess the effects of regular SF intake between 1 and 2 months of age on food sensitization development by 6 months of age.

METHODS

Using data from a randomized controlled trial of a birth cohort from four Japanese hospitals that assessed cow's milk allergy development, we performed a retrospective cohort study of 235 infants who avoided cow's milk formula and supplemented breastfeeding with SF as required between 1 and 2 months of age. Regular SF intake was defined as SF consumption of ≥14 days per month and ≥1350 ml per month. Food sensitization was defined as positive skin prick test reactions to hen's egg, cow's milk, wheat, and/or soy. Using multivariable logistic regression models that adjusted for parental, perinatal, and environmental factors, we calculated the adjusted odds ratios of regular SF intake for food, hen's egg, and cow's milk sensitization by 6 months of age.

RESULTS

From the 235 participants, 114 (48.5%) had regular SF intake. The adjusted odds ratios of regular SF intake for food, hen's egg, and cow's milk sensitization were 0.32 (95% confidence interval: 0.16-0.62, p = .0007), 0.42 (0.20-0.88, p = .02), and 0.33 (0.14-0.81, p = .02), respectively.

CONCLUSION

Regular SF intake between 1 and 2 months of age in infants avoiding cow's milk formula was significantly associated with a reduced risk of food sensitization in infancy.

Managing Cow's Milk Protein Allergy in Indonesia: A Cost-effectiveness Analysis of Hypoallergenic Milk Formulas from the Private Payers' Perspective

Background: Cow's milk protein allergy is very common in early childhood. Extensively hydrolyzed formulas are recommended in the first-line management of cow's milk protein allergy in non-breastfed children. Choice of formulas should be informed by efficacy and cost data. Objectives: This study aims to compare the cost-effectiveness of extensively hydrolyzed casein formula with Lacticaseibacillus rhamnosus Gorbach Goldin (EHCF+LGG), extensively hydrolyzed whey formula (EHWF), amino acid formula, and soy formula in the first-line management of cow's milk protein allergy in non-breastfed children in Indonesia. Methods: A trial-based decision analytic cohort model was adapted to simulate the occurrence of cow's milk protein allergy symptoms or being symptom free. The model was based on a prospective nonrandomized study that followed up children for 36 months. Costs and health consequences were discounted at 3% annually. Resources required to manage cow's milk protein allergy and unit costs for clinical appointments and exams were based on a panel of 15 clinicians, from a private payers' perspective. Other unit costs were based on publicly available national data. Results were reported as cost per additional child free from allergic manifestations or per additional immunotolerant child at 3 years, and per life-years under the same conditions. Uncertainty was assessed using deterministic and probabilistic sensitivity analysis. Results: Children receiving EHCF+LGG were associated with more symptom-free time, a higher probability of cow's milk tolerance at 3 years, and lower healthcare resources and transportation use when compared with children receiving other formulas (with 38%-49% lower costs). Formula costs were lower for soy, but EHCF+LGG was predicted to save 9% and 54% of overall costs compared with extensively hydrolyzed whey formula and amino acid formula, respectively. Results were robust to sensitivity analyses. Conclusion: Use of EHCF+LGG resulted in more symptom-free time and the highest 3-year probability of cow's milk tolerance. It also led to healthcare resource and transportation savings when compared with other hypoallergenic milk formulas. Soy formula remained an alternative if formula price represents a major constraint.

Correlation between nutritional status and children's activity with food allergy: A cross-sectional study

Background

Food allergy in children affects nutritional status that limits their daily activities to prevent eating various foods to avoid allergic reactions.

Objective

Analyzing the relationship between nutritional status and daily activities in children with food allergies.

Methods

This study used a cross-sectional design that was carried out on children diagnosed with food allergies who underwent outpatient management of food allergies. The data were collected from January to May 2021 that included participant characteristics, nutritional status, and daily activities. Data analysis used Chi-Square and spearman rho test with p < 0.05.

Results

There was a significant relationship between age and FAIS (CI 1.83-4.24; p = 0.025). In addition, there was no significant relationship between the affected organs and FAIS (OR = 0.174; p = 0.052). Meanwhile, the relationship between nutritional status and FAIS was significant (OR = 0.161; p = 0.007). There was no significant relationship between parental education and FAIS (OR = 0.817; p = 0.776) as well as sex of the child and FAIS (OR = 0.982; p = 0.977).

Conclusion

Daily activities of children with food allergies are influenced by the nutritional status of children and children's age in choosing food.
