The article describes a clinical case of pseudo-Bartter's syndrome (PBS) in a 5-month-old child with cystic fibrosis. Pseudo-Bartter's syndrome is one of the major complications of cystic fibrosis with potential lethal outcome, which develops in patients in consequence of salt losing in the excessive sweating in hot climate conditions, in infants with an imperfect thermal control system associated with febrile states, alongside non-compliance with recommendations for additional sodium and chlorine salt supply and correction of water load, and can be enhanced by electrolyte spillage in vomiting and diarrhoea. PBS manifests predominantly during the first year of life and is characterised by hypokalaemia, hypochloraemia, metabolic alkalosis, dehydration, plasma renin overactivity, increased high blood aldosterone concentration. The clinical picture is so much non-specific that with no diagnosis of cystic fibrosis, the identification of hypochloremic alkalosis is significantly complicated, and untimely emergency medical treatment quickly leads to death. Awareness of physicians, electrolyte level control, training of parents to recognize the first alarm signs, to carry out preventive measures in situations that boost the metabolic disorders, allows providing adequate correction in due time and prevent the development of life-threatening conditions.
Key words: cystic fibrosis, metabolic alkalosis, pseudo-Bartter's syndrome.
