Dysarthria in a patient with probable acquired chloridorrhea

Acute pre-renal failure: acquired chloride diarrhea after bowel resection

A 58-year old male with a history of small bowel resection and ileostomy presented with severe dehydration and high ostomy output. Laboratory investigation indicated hypochloremia, hypokalemia, hyponatremia, metabolic alkalosis, chloride-rich diarrhea, acute renal failure, and low urinary chloride excretion. Due to striking similarities to congenital chloridorrhea (CCD) reported in neonates, we empirically diagnosed acquired chloridorrhea (ACD, chloride diarrhea). This is a rare disorder resulting in profuse chloride-rich diarrhea and classic metabolic derangements affecting adults with chronic intestinal inflammation, often in association with bowel surgery. In this report, we review the relevant literature and discuss the genetic defects likely contributing to both the congenital and acquired forms of chloridorrhea.

Severe metabolic alkalosis and recurrent acute on chronic kidney injury in a patient with Crohn's disease

Background

Diarrhea is common in patients with Crohn's disease and may be accompanied by acid base disorders, most commonly metabolic acidosis due to intestinal loss of bicarbonate.

Case Presentation

Here, we present a case of severe metabolic alkalosis in a young patient suffering from M. Crohn. The patient had undergone multiple resections of the intestine and suffered from chronic kidney disease. He was now referred to our clinic for recurrent acute kidney injury, the nature of which was pre-renal due to profound volume depletion. Renal failure was associated with marked hypochloremic metabolic alkalosis which only responded to high volume repletion and high dose blockade of gastric hypersecretion. Intestinal failure with stomal fluid losses of up to 5.7 litres per day required port implantation to commence parenteral nutrition. Fluid and electrolyte replacement rapidly improved renal function and acid base homeostasis.

Conclusions

This case highlights the important role of gastrointestinal function to maintain acid base status in patients with Crohn's disease.
