“…Many studies have reported that drugs especially thiazide diuretics are a major cause of hyponatremia in elderly. [15][16][17][18] Analysis of the causes of hyponatremia in the present study patients revealed that most of the patients had multiple etiological factors in elderly patients with hyponatremia. Other factors found to reduce dietary salt intake were intake of only liquid feeds and patients put on Ryle's tube feeds.…”

INTRODUCTIONElectrolyte imbalance is one of the leading causes of metabolic encephalopathy as studied and discussed among various literatures previously. Sodium is generally the most important element causing metabolic encephalopathy in critically ill patients as found out by previous researches done. 1,2 The normal value of sodium is 135 mmol/l. Both hyponatremia and hypernatremia can cause metabolic encephalopathy. Hyponatremia is defined as serum sodium of less than 135meq/L. [3][4][5][6][7] Hyponatremia is the ABSTRACT Background: Hyponatremia is the most common electrolyte disturbance encountered in clinical practice. Hyponatremia frequently develops in hospitalized patients, especially in metabolic encephalopathy patients, their causes are multiple. Symptomatology depends more on the rate of development of the electrolyte abnormality than on its severity. We undertook this study to determine etiological, clinico-lab profile and differential diagnosis in a group of hyponatremic patients. Methods: We included retrospectively 50 patients of hyponatremia admitted in medical intensive care unit between June 2013 and May 2014. We excluded all patients who presented with chronic hyponatremia, chronic use of diuretics and recent cases undergoing surgery and chronic cases of malnutrition and those with age below 18 years. Data were analyzed by univariate methods, followed by multivariate analysis. Results: Among the 50 patients with hyponatremia, 42% of encephalopathy patients had metabolic encephalopathy. Majority who developed hyponatremia had age between 61 to 80 years. Clinical profile of patients with hyponatremia was revealed that most of the patients with hyponatremia were observed having confusion followed by nausea/vomiting, delirium, seizure. The most common etiology of metabolic encephalopathy with hyponatremia is diuretic induced, followed by diabetic ketoacidosis, chronic liver disease, chronic kidney disease, SIADH and hypothyroidism. The common co-morbid conditions for hyponatremia were hypertension 55.93%, diabetes mellitus 43.85%, and chronic renal failure 35.29%. In the patients with hyponatremia high urine sodium level suggests that most of the patients had hyponatremia due to renal loss of sodium other than extra renal cause. Conclusions:In the present study, hypertension was found a major risk factor for hyponatremia. Common causes of hyponatremia found are intake of diuretics and excessive renal loss. Most of the hypertensive patients in the present study group were on thiazide or potassium sparing diuretics. Diabetes mellitus and dyslipidemia were important comorbidities of hyponatremia.

BACKGROUND Hyponatraemia is one of the commonest electrolyte abnormalities among admitted patients. It is also the commonest electrolyte abnormality associated with morbidity and mortality. Hence, we aimed to study the clinical and aetiological profile of patients admitted with severe hyponatraemia in Pondicherry Institute of Medical Sciences, Pondicherry. MATERIALS AND METHODS A prospective observational study conducted at tertiary care hospital in South India during last 18 months. All patients above age of 18 presenting with serum sodium less than or equal to 125 mEq/L were included in the study. Detailed medical and surgical history was recorded. Routine investigation like complete haemogram, renal function test, serum electrolytes, thyroid function test, serum cortisol and urine spot sodium and osmolality were done. Descriptive variables were expressed in mean and standard deviations. They were compared using Mann-Whitney U test and x 2 test.
