Epidemic of gastro-oesophageal reflux in young infants

The paper on Managing gastro-oesophageal reflux in infants highlights
the importance of its recognition and the rationale for the treatment in
the symptomatic case (1).

Gastro-oesophageal reflux (passage of gastric contents into distal
oesophagus) is considered as physiological in majority of the infants;
however symptomatic reflux, often associated with regurgitation extending
above the distal oesophagus accounts for over 7 % of infants to seek
medical attention (2). The symptoms pose a management dilemma for the
practitioner to differentiate between a simple reflux and the ones that
need treatment. We have observed that an increasing number of infants are
referred to our Feeding Clinic with the symptoms of feed regurgitation and
gastro-oesophageal reflux disease (GORD).

The main symptoms of GORD, feed regurgitation and crying, are also
common in normal infants and sometimes make it difficult to differentiate
between physiological reflux and pathological GORD (3). However, infant
Gastroesophageal Reflux Questionnaire Revised (i-GERQ-R) has been
validated as reliable and clinically responsive measure of infant GORD
symptoms in an international observational study (4, 5).

There has been steady decline in the rate of Sudden Infant Death
Syndrome (SIDS) and Unascertained Deaths in the last two decades. This has
been partly attributed to the increasing public awareness about the safety
of infants sleeping in supine position (6). Previous studies have shown
that prone and left lateral position reduces GOR in preterm infant and it
has been postulated that this may be due to the delayed gastric emptying
in supine position and that gastric delaying is the starting phenomenon in
half of the cases of GORD (7). Relationship of nursing in supine position
and the pathogenesis of GORD in young infants is not known and its causal-
effect needs to be excluded.

Impact of baby's reflux on parents

a) Feeding problems

A persistently crying baby who is refusing feeds is a source of great
distress to the parents and causes considerable loss of parental sleep;
many parents feel that the magnitude and severity of the reflux symptoms
and its impact on the family are not fully appreciated by the health
professionals. It has been clearly shown that feeding problems,
characterised by oral motor dysfunction, episodes of dysphagia, food
aversion and negative feeding practices for the mother and baby, are
common in
infants with GORD (8). In our Feeding Clinic, we see a significant
proportion of mothers of refluxing babies, experiencing low self esteem
and mood low levels related to negative feeding practice experience;
studies have also demonstrated adverse psychological effects of the
refluxing as anxiety and depression in mothers of infants with GORD (9).

b) Apparent life threatening event (ALTE)

ALTE refers to a constellation of unexpected patho-physiologic events
in an otherwise infant that is witnessed by and always very distressing to
the caregiver. The most typical symptoms of ALTE syndrome are: breathing
disorders with or without apnoea, changes in skin colour as pallor or
cyanosis, disorder of muscle tension as hypo/hyper-tonia and/or frank
anoxic seizure, gagging, choking, salivation, loss of consciousness,
cardiac arrhythmia and bradycardia (10). While these symptoms are non-
specific and can occur in a variety of disorders, GORD has been observed
to be one of the leading causes (10, 11).

Occurrence of ALTE symptoms is a frightful experience for the
parents/carer. As many babies seem to make a full recovery by the time
they are seen by a health professional, the true nature of the symptoms
and its impact on the family may be underestimated. While most paediatric
units have access to clear guidelines for the management of ALTE in young
infants, there is inconsistency of approach among the health professionals
(12). In our region, we consider severe or recurrent ALTE symptoms as
potential SIDS and following a period of in-patient observations, with
appropriate investigations, we offer extended home care with health
visitor and paediatrician input and use of apnoea alarm monitoring,
through the national CONI (Care Of Next Infant) programme.

Conclusion

(a) While physiological feed regurgitation and reflux are common in
infants, symptomatic reflux with vomiting, feed refusal, persistent
crying, arching and failure to thrive suggests a pathological reflux and
merits thorough review by an experienced clinician.

(b) Medical professionals should be aware of the psycho-social impact
of the condition on the family.

(c) Further studies are indicated to see if sleeping the infant in
supine position contributes to or aggravates what would otherwise have
been a physiological gastro-esophageal reflux.
