e experienced a case of severe hyponatremia (serum Na
level, 104 mEq/L) while treating with a thiazide diuretic
for hypertension. Then, we surveyed the frequency of patients
with profound hyponatremia (<125 mEq/L) at the admission
to Matsumoto Medical Center Matsumoto Hospital from
May 2016 to April 2017 during one year prior to the hospital
admission of the index patient. The patients with profound
hyponatremia were 127 in 4,223 newly admitted patients. Out
of 127 patients, 118 patients were aged 65 years or older.
Ten patients with severe hyponatremia (<115 mEq/L) were all
older than 65 years, in which two patients including the index
patient were prescribed a thiazide diuretic. Table 1 shows the
frequency of patients with profound hyponatremia each month
during the surveillance period. It is of interest that seasonal
variation was found in the number of the patients with profound
hyponatremia. The frequency was significantly (p=0.013,
unpaired t-test) low during the relatively cold period around
Matsumoto City in Japan from November to March compared
to the other period in the year. Such seasonal variation suggests
that the occurrence of profound hyponatremia is to no small
extent attibutable to elderly patients’ living environment.
This finding is also expected to help healthcare providers in
Preventive Medicine and Public Health.
