Salicylate hepatotoxicity: the potential role of hypoalbuminemia.
Seventeen patients suffering from an initial attack of acute rheumatic fever were studied during treatment with phenoxymethyl penicillin and salicylates (600 mg orally every 4 or 6 hours). Elevated transaminase (SGOT) levels occurred in nine patients. The SGOT levels were directly related to serum salicylate levels (r = 0.668) and inversely to the serum albumin level (r = -0.418). SGOT response was greater in patients with a serum albumin of less than 3.5 g/dl (P < 0.001). In hypoalbuminemia, the ratio of free salicylate to bound salicylate rises and the free salicylate might be more active and thus more hepatotoxic even at relatively low total serum salicylate levels. In all patients with hypoalbuminemia of less than 3.5 g/dl, close monitoring the SGOT is advisable, especially if the level of total serum salicylate is 15 mg/dl or higher.
