How mothers interact with children with suspected cow's milk allergy symptoms

Gastrointestinal Symptoms of Food Challenge-proven Non-IgE Cow's Milk Allergy Are Dissipated by Early School Age

OBJECTIVES

The aim of this study was to evaluate the current well-being and dietary restrictions in children 6 years after food challenge-confirmed diagnosis of non-IgE cow's milk protein allergy, compared to peers with gastrointestinal symptoms but negative food challenge. This study aimed to evaluate the diagnostic process retrospectively.

METHODS

This is an Internet-based survey for mothers whose children underwent 6 years ago the double-blind, placebo-controlled food challenge for cow's milk (CM) because of gastrointestinal symptoms causing suspicion of non-IgE CM protein allergy. Concurrent dietary restrictions, overall well-being, medical history, and retrospective views on the food challenge were queried using a study-specific questionnaire, the Quality of life using PedsQL general score and parental stress with the Parenting Stress Index questionnaire.

RESULT

Mothers of 42 children (23 girls), median age of 6.7 years (range 5.7-8.6), participated in the survey, the response rate was 70%. All children now consumed cow's milk protein. The only food restrictions reported were empirical lactose-free diets in 7 children (17%). One-third of the children in both groups were presently reported to have eating-related issues such as picky eating. Quality of life was good and present parenting stress was average in both groups. The majority of the mothers (87%) felt positive or neutral about the food challenge performed in infancy.

CONCLUSIONS

The non-IgE CM allergy with gastrointestinal symptoms diagnosed in infancy was a transient condition with good outcome. At an early school age, nearly all children have a good quality of life and a regular diet. The use of the double-blind, placebo-controlled food challenge was well-endorsed.

Attention to Faces Expressing Negative Emotion at 7 Months Predicts Attachment Security at 14 Months

To investigate potential infant-related antecedents characterizing later attachment security, this study tested whether attention to facial expressions, assessed with an eye-tracking paradigm at 7 months of age (N = 73), predicted infant-mother attachment in the Strange Situation Procedure at 14 months. Attention to fearful faces at 7 months predicted attachment security, with a smaller attentional bias to fearful expressions associated with insecure attachment. Attachment disorganization in particular was linked to an absence of the age-typical attentional bias to fear. These data provide the first evidence linking infants' attentional bias to negative facial expressions with attachment formation and suggest reduced sensitivity to facial expressions of negative emotion as a testable trait that could link attachment disorganization with later behavioral outcomes.

How mothers perceive infants with unspecific gastrointestinal symptoms suggestive of cow's milk allergy?

AIM

To determine whether specific infant behavioural characteristics are present in children suspected of cow's milk allergy because of gastrointestinal symptoms.

METHODS

We prospectively recruited 57 children (median age 8.7 months) with a suspicion of gastrointestinally manifested cow's milk protein allergy (GI-CMPA). None had detectable cow's milk-specific IgE. Mothers were asked to complete the Parenting Stress Index (PSI) Child Domain, and those with children below 18 months of age (n = 49) also the Infant Temperament Questionnaire (ITQ). GI-CMPA was diagnosed with the double-blind, placebo-controlled food challenge. Control group (n = 22) consisted of patients (age range 4-26 months), attending the Pediatric Allergy Unit, who did not have diagnosed or suspected food allergies.

RESULTS

The scores were significantly higher for the PSI (n = 48) Child Domain (p < 0.0001) and for the ITQ (n = 44) subscale Difficultness (p = 0.0045) compared with the control patients without suspected/diagnosed food allergy. The difference between the challenge positive (n = 18) and negative (n = 39) patients remained statistically insignificant. After 6 months, in both groups, the scores (PSI Child Domain p = 0.0004, ITQ Difficultness p = 0.0393) were lower, but the ITQ Difficultness score still remained higher than in the controls (p = 0.0453).

CONCLUSION

The mothers often perceive infants with unspecific symptoms suggestive of GI-CMPA as demanding and temperamentally difficult.
