Case report: Congenital central hypoventilation syndrome (CCHS)
M Ranjan
Hull Royal Infirmary, UK
Introduction:
CCHS is a rare disorder found in less than one per 100,000 new-borns. It affects the central and autonomous
nervous system which controls many of the autonomic function in the body. The underlying cause is dominant mutation in
the PHOX2B gene. The mutations are stable in transmission from generation to generation but penetrance and phenotype can
still vary significantly.
Case Report:
A new-born was born in good condition following induction of labour for polyhydramnios at term. She developed
respiratory distress at 4 hours of age needing intubation and ventilation at local hospital. She failed extubation once at local
hospital and twice at tertiary care with marked CO2 retention during sleep. Her elder sibling of 4 years is being investigated
for obstructive sleep apnoea and awaiting adenotonsillectomy. Rest of the history and examination were normal except poor
antigravity movements during first few days of life. CCHS was confirmed by genetic testing for PHOX2B gene mutation
after excluding metabolic disorders and spinal muscular atrophy (SMA). She was switched to non-invasive ventilation and
transferred to long term ventilation (LTV) center specialized for tracheostomy and long-term home ventilation. We avoided
suxamethonium during intubation. Family was referred for genetic counseling and professionals involved in the care of elder
sibling were made aware of this diagnosis after parental consent.
Conclusion:
This case illustrates undiagnosed mild cases may be still at large and the importance of avoiding drugs causing
prolonged neuromuscular blockade such as suxamethonium, atracurium, gentamicin etc. in hypotonia until spinal muscular
disorders are excluded, to prevent unwarranted hyperkalemia; maintaining high index of suspicion in mildly symptomatic
cases to avoid associated long-term morbidity and mortality and to permit early genetic testing and counseling for families;
and referring to the local LTV specialist before a final decision to progress down the LTV pathway.
