Insights
Congenital chloride diarrhea (CCD) management improved with spironolactone, reducing the need for high electrolyte doses. This treatment supported normal development in a pediatric case, though hormonal monitoring remains crucial.
Area of Science:
- Pediatric Gastroenterology
- Medical Genetics
- Endocrinology
Background:
- Congenital chloride diarrhea (CCD) is a rare inherited disorder affecting intestinal ion transport.
- Early diagnosis and management are critical for preventing severe electrolyte imbalances and complications.
Observation:
- A case of CCD diagnosed in infancy presented with severe diarrhea, abdominal distension, and electrolyte abnormalities.
- Prenatal ultrasound revealed fetal hydrops and hydramnios, suggesting intrauterine complications.
Findings:
- Spironolactone administration facilitated electrolyte correction (hypochloremia, hyponatremia) with reduced potassium chloride (KCl) and sodium chloride (NaCl) requirements.
- The patient achieved normal growth and development by 7.5 years of age despite persistent chloriduria and secondary hyperaldosteronism.
Implications:
- Spironolactone may be a valuable adjunct in managing neonatal CCD, potentially simplifying electrolyte replacement therapy.
- Long-term monitoring of the renin-angiotensin-aldosterone system is recommended for optimal management of CCD patients.
- This case highlights the importance of multidisciplinary care in rare genetic disorders.
Abstract:
We report on a girl having congenital chloride diarrhea (CCD) who has been followed for 7 years and 6 months sequentially. Dilated intestinal loops, marked enlargement of the abdominal circumference of the fetus and hydramnios were noted by ultrasound examination at 31 weeks of gestation. After delivery by cesarean section for hydramnios, she excreted profuse watery yellow green stools with marked abdominal distension. At 4 months of age, hypochloremia, hyponatremia and a high concentration of chloride in the stool were identified. She was diagnosed as having CCD. Because it was difficult to administer a large volume of potassium chloride (KCl), and sodium chloride (NaCl), we decided to administer spironolactone. After administration of spironolactone, we could generate correct serum electrolytes using less amounts of KCl. At 7 years and 6 months of age, her body size was within normal limits and her intellectual, mental and physical development had been normal. In spite of normal serum electrolytes, blood pH and the presence of chloriduria, secondary hyperaldosteronism was noted. We consider that spironolactone may be useful to decrease the amount of KCl administration in the neonatal period, but frequent measurements of renin, angiotensin and aldosterone would be necessary for adequate control in CCD cases.
