title: Factors related to quality of life in patients with cirrhosis and ascites: relevance of serum sodium concentration and leg edema.
abstract: OBJECTIVE
  Hyponatremia is common in patients with cirrhosis and ascites and is associated with significant neurological disturbances. However, its potential effect on health-related quality of life (HRQL) in cirrhosis has not been investigated. We aimed at assessing the relationship between serum sodium concentration and other clinical and analytical parameters on HRQL in cirrhosis with ascites.
  
  
  METHODS
  A total of 523 patients with cirrhosis and ascites were prospectively investigated. Assessment of HRQL was done with the Medical Outcomes Study Short-Form 36 (SF-36) questionnaire, which is divided into 8 domains, summarized in two components: physical component score (PCS) and mental component score (MCS). Demographic, clinical, and analytical data at baseline were analyzed for their relationship with HRQL.
  
  
  RESULTS
  In multivariate analysis, independent predictive factors associated with an impaired PCS were non-alcoholic etiology of cirrhosis, severe ascites, history of previous episodes of hepatic encephalopathy and falls, presence of leg edema, and low serum sodium concentration. With respect to MCS, only two factors were associated with the independent predictive value: low serum sodium concentration and treatment with lactulose or lactitol. In both components, the scores decreased in parallel with the reduction in serum sodium concentration. Variables more commonly associated with the independent predictive value in the individual 8 domains of PCS and MCS were presence of leg edema and serum sodium concentration, 7 and 6 domains, respectively.
  
  
  CONCLUSIONS
  Serum sodium concentration and presence of leg edema are major factors of the impaired HRQL in patients with cirrhosis and ascites.
