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.

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, weightfor-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.
