Role of admission serum albumin levels in patients with intracerebral hemorrhage.

Low serum albumin levels have been reported to be an independent predictor of increased morbidity and mortality in multiple disease conditions. The aim of our study was to identify the impact of low serum albumin levels on mortality and outcomes at discharge in patients with intracerebral hemorrhage. We retrospectively reviewed our prospective database of patients with intracerebral hemorrhage from January 2010 to December 2011. Patients were dichotomized into two groups based on their serum albumin levels upon admission. Hypoalbuminemia was defined as serum albumin levels ≤3.4 g/dl. The two groups were compared using Fisher's exact test for categorical variables and t test for continuous variables. Poor outcome was defined as death or discharge to a long-term nursing facility (modified Rankin Score 4-6). Out of 97 patients admitted with intracerebral hemorrhage, 90 met our inclusion criteria (42 had normal levels and 48 had hypoalbuminemia). The baseline characteristics, risk factors, etiology, location and volume of intracerebral hemorrhage, admission blood glucose, white cell count, length of hospital stay, length of intensive care unit stay, and complications were similar between both groups. Although admission hypoalbuminemia did not impact in-hospital mortality (28 vs 24 %, p = 0.635), there was a significant increase in poor outcomes at discharge (59 vs 31 %, p = 0.009) (OR 1.8; 95 % CI; 1.2-2.8). Similar to other diseases, hypoalbuminemia was associated with poor functional outcomes in patients with intracerebral hemorrhage. This will need to be confirmed in larger prospective studies before adopting therapeutic and preventive strategies in future.
