OBJECTIVE
Some H7N9 patients presented with hyponatremia. But whether SIAD could be the etiology of hyponatremia in H7N9 pneumonia is still not known.
METHODS
A H7N9 patient was enrolled. Clinical sign were evaluated. Effective osmolality, urinary osmolality, urinary sodium, thyroid function, adrenal function, 25(OH) Vitamin D and cellular immune function were measured.
RESULTS
(1) The results showed low serum osmolality, inappropriately elevated urine osmolality, elevated urine sodium concentration, low serum uric acid concentration, relatively normal serum creatinine concentration, normal acid-base and potassium balance, normal adrenal and thyroid function in our patient. (2) Our patient showed vitamin D deficiency and decline of cellular immune function.
CONCLUSIONS
Some H7N9 pneumonia could cause SIAD. Early detection and appropriate treatment of SIAD in H7N9 pneumonia might be important. Our patient showed vitamin D deficiency and decline of cellular immune function.
