Randomized trial demonstrates relationship between chronic diarrhea and tricuspid regurgitation in a woman, highlighting the need for carcinoid syndrome evaluation.
Key Points
To explore the presentation of carcinoid syndrome in a patient with chronic diarrhea and heart issues.
Clinical evaluation of symptoms and vital signs, including serum sodium assessment,
Imaging through computed tomography (CT) for tumor identification,
Biochemical analysis of serum chromogranin A and urinary 5-HIAA for carcinoid diagnosis.
The patient presented with a serum sodium concentration of 114 mmol/L (reference range 135-145) indicating severe hyponatremia.
Transthoracic echocardiography revealed severe tricuspid regurgitation consistent with carcinoid heart disease (CHD).
Treatment with isotonic saline, octreotide, and furosemide improved the patient's hyponatremia and associated symptoms.
