This translation by the NDI Foundation is to assist the lay reader. To provide a clear, accessible interpretation of the original article, we eliminated or simplified some technical detail and complicated scientific language. We concentrated our translation on those aspects of the article dealing directly with NDI. The NDI Foundation thanks the researchers for their work toward understanding and more effectively treating this disorder.

After release from the hospital, the patient did not return for follow-up. He returned to the hospital two months later complaining of muscle weakness, increasing thirst and urine output, and bouts of alcohol abuse. The authors noted the patient's polyuria (chronic, excessive urination), polydipsia (chronic, excessive thirst), serum hyperosmolality, extreme potassium depletion, and elevated blood levels of the antidiuretic hormone, arginine vasopressin (AVP). They concluded that their patient also had nephrogenic diabetes insipidus (NDI).
The authors proposed the patient's NDI was caused by the elevated levels of blood calcium brought on by the patient's primary hyperparathyroidism. Polyuria, in combination with the tubular acidosis of the patient's kidneys, produced a severe potassium depletion, and this exacerbated the patient's NDI.
To correct the patient's hyperparathyroidism, the authors performed surgery on him, removing three and one-half of his parathyroid glands. After the surgery, the patient's NDI disappeared, confirming it was caused by the metabolic conditions created by his primary hyperparathyroidism.
