Objective: Some H7N9 patients presented with hyponatremia. But whether SIAD could be the etiology of hyponatremia in H7N9 pneumonia is still not known. Design, setting, and participants: 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. © 2014 The Authors.
