Association of Hyponatremia and Encephalopathy in Patients with Chronic Liver Disease
Keywords:CLD, hyponatremia, hepatic encephalopathy
Objective: To determine the association of hyponatremia in chronic liver disease patients with presentation of hepatic encephalopathy (HE) at Isra university Hospital Hyderabad.
Methods: This study was cross sectional and carried out at medicine and gastroenterology department of Isra university Hospital Hyderabad and MMC Mirpurkhas. Study duration was from September 2015 to March 2016. All the cases with age more than 25 years, both genders after diagnosis of chronic liver disease with sign and symptoms of Hepatic Encephalopathy were selected in this study. Blood sample for serum sodium level, was send to diagnostic laboratory of the hospital. Hyponatremia was classified as: 130–135 mEqL (mild), 125–130 mEq/L (moderate) and < 125 mEq/L (severe). Hepatic encephalopathy was categorized according to the West Haven classification (4 grades).
Results: Total number of cases was 80. Mean age was 48 + 8.5 years. 55 (68.5%) patients were male. Majority of cases, 55 (68.5%) patients were infected with HCV. 40% patients had normal level of sodium, 25% had mild, 20% had moderate while 15% patients had severe hyponatremia. On the grading of encephalopathy, 30 (37.5%) patients had grade 1 encephalopathy while 25/(31.2%) patients had grade 2, 15/(18.8%) had grade 3 while 10 (12.5%) patients hade grade 4. The serum sodium levels significantly decreased with increasing severity of hepatic encephalopathy (P = 0.001).
Conclusion: We concluded that the hyponatremia is significantly linked with Hepatic Encephalopathy (HE) in patients having chronic liver disease (CLD).
