Unlabelled: We describe a case of iatrogenic pseudo-Bartter syndrome caused by administration of prostaglandin E1 (PGE1 alprostadil). Although the use of i.v. PGE1 is a well-established pharmacological therapy in neonates with a ductus-dependent congenital cardiopathy to ensure ductus-dependent flow, we could only find one other report on pseudo-Bartter syndrome related to PGE1 infusion.
Conclusion: Primary Bartter syndrome is associated with endogenous increased levels of prostaglandins. Therefore, we postulate that the dose of prostaglandin E1 administered, immaturity and the genetic background are all relevant factors involved in the phenotypic presentation of iatrogenic pseudo-Bartter syndrome in this preterm infant.

Pseudo-Bartter syndrome: A CFTR-related disorder?

This case report presents a 14-month-old boy with a history of cystic fibrosis (CF) carrier status, diagnosed following a positive newborn screening for CF (CF-NBS), who developed symptoms suggestive of Pseudo-Bartter syndrome (PBS). Despite initial evaluations not meeting CF diagnostic criteria, subsequent investigations revealed an intermediate sweat chloride concentration, a second CFTR mutation, and CFTR dysfunction through rectal organoid morphology analysis (ROMA) consistent with CFTR-related disorder (CFTR-RD). This case raises important considerations regarding the diagnosis and management of CFTR-RD.

Cystic fibrosis is a multisystem disease with extremely variable onset, symptoms and course. One of the onset modality but also a complication of the disease is the pseudo-Bartter syndrome, characterized by hyponatremia, hypochloremic dehydration and metabolic alkalosis in absence of any renal disease. This syndrome occurs more frequently in the first year of life and has a peak in the summer.

Article Synopsis
- The study focuses on children with cystic fibrosis presenting symptoms similar to pseudo-Bartter syndrome, aiming to improve understanding of this condition.
- Three children from Hunan Children's Hospital showed critical electrolyte imbalances and genetic mutations characteristic of cystic fibrosis, with a literature review identifying further cases and common complications.
- Early symptoms of cystic fibrosis may not include classic respiratory issues; therefore, medical professionals should consider CF-PBS in infants presenting with significant metabolic disturbances and delay genetic testing for timely diagnosis.
A case of pseudo-Bartter/Gitelman syndrome caused by long-term laxative abuse, leading to end-stage kidney disease.

Pseudo-Bartter/Gitelman syndrome (PBS/PGS) is a disorder that presents with hypokalemia and metabolic alkalosis resembling Gitelman syndrome (GS) due to secondary factors, such as lifestyle and /or medicines. Notably, PBS/PGS is more likely to cause renal dysfunction than GS. We report the first case of PBS/PGS due to long-term laxative abuse leading to end-stage kidney disease (ESKD).
